Introduction: Rates of subtotal cholecystectomy (STC) are increasing in response to challenging cases of laparoscopic cholecystectomy (LC) to avoid bile duct injury, yet are associated with significant morbidity. The present study identifies risk factors for STC and both derives and validates a risk model for STC., Methods: LC performed for all biliary pathology across three general surgical units were included (2015-2020). Clinicopathological, intraoperative and post-operative details were reported. Backward stepwise multivariable regression was performed to derive the most parsimonious predictive model for STC. Bootstrapping was performed for internal validation and patients were categorised into risk groups., Results: Overall, 2768 patients underwent LC (median age, 53 years; median ASA, 2; median BMI, 29.7 kg/m 2 ), including 99 cases (3.6%) of STC. Post-operatively following STC, there were bile leaks in 29.3%, collections in 19.2% and retained stones in 10.1% of patients. Post-operative intervention was performed in 29.3%, including ERCP (22.2%), laparoscopy (5.0%) and laparotomy (3.0%). The following variables were positive predictors of STC and were included in the final model: age >  60 years, male sex, diabetes mellitus, acute cholecystitis (AC), increased severity of AC (CRP > 90 mg/L), ≥ 3 biliary admissions, pre-operative ERCP with/without stent, pre-operative cholecystostomy and emergency LC (AUC = 0.84). Low, medium and high-risk groups had a STC rate of 0.8%, 3.9% and 24.5%, respectively., Discussion: The present study determines the morbidity of STC and identifies high-risk features associated with STC. A risk model for STC is derived and internally validated to help surgeons identify high-risk patients and both improve pre-operative decision-making and patient counselling., (© 2024. Crown.)

Aim: This study aimed to investigate the impact of preoperative gallbladder drainage and the specific drainage method used on surgical outcomes in patients undergoing surgery for acute cholecystitis., Methods: This single-center retrospective cohort study included 221 patients who underwent early cholecystectomy between January 2016 and December 2020. Clinical data and outcomes of 140 patients who did not undergo drainage, 22 patients who underwent preoperative percutaneous transhepatic gallbladder drainage (PTGBD), and 59 patients who underwent preoperative endoscopic naso-gallbladder drainage (ENGBD) were compared., Results: There was no difference in the operation time, blood loss, postoperative complications, or length of postoperative hospital stay between patients who did and did not undergo drainage. Among patients who underwent drainage, there was no difference between the ENGBD and PTGBD groups in operation time, blood loss, or postoperative complications; however, more patients in the PTGBD group underwent laparotomy and had a significantly longer postoperative hospital stay. The presence and type of drainage were not risk factors for postoperative complications., Conclusion: The presence or absence of preoperative gallbladder drainage for acute cholecystitis and the type of drainage may not significantly affect surgical outcomes., (Copyright © 2024 Asian Surgical Association and Taiwan Society of Coloproctology.

Objectives: Some patients undergo both computed tomography (CT) and ultrasound (US) sequentially as part of the same evaluation for acute cholecystitis (AC). Our goal was to perform a systematic review and meta-analysis comparing the diagnostic performance of US and CT in the diagnosis of AC., Materials and Methods: Databases were searched for relevant published studies through November 2023. The primary objective was to compare the head-to-head performance of US and CT using surgical intervention or clinical follow-up as the reference standard. For the secondary analysis, all individual US and CT studies were analyzed. The pooled sensitivities, specificities, and areas under the curve (AUCs) were determined along with 95% confidence intervals (CIs). The prevalence of imaging findings was also evaluated., Results: Sixty-four studies met the inclusion criteria. In the primary analysis of head-to-head studies (n = 5), CT had a pooled sensitivity of 83.9% (95% CI, 78.4-88.2%) versus 79.0% (95% CI, 68.8-86.6%) of US (p = 0.44). The pooled specificity of CT was 94% (95% CI, 82.0-98.0%) versus 93.6% (95% CI, 79.4-98.2%) of US (p = 0.85). The concordance of positive or negative test between both modalities was 82.3% (95% CI, 72.1-89.4%). US and CT led to a positive change in management in only 4 to 8% of cases, respectively, when ordered sequentially after the other test., Conclusion: The diagnostic performance of CT is comparable to US for the diagnosis of acute cholecystitis, with a high rate of concordance between the two modalities., Clinical Relevance Statement: A subsequent US after a positive or negative CT for suspected acute cholecystitis may be unnecessary in most cases., Key Points: When there is clinical suspicion of acute cholecystitis, patients will often undergo both CT and US. CT has similar sensitivity and specificity compared to US for the diagnosis of acute cholecystitis. The concordance rate between CT and US for the diagnosis of acute cholecystitis is 82.3%., (© 2024.

Purpose: After the Tokyo 2018 guidelines (TG2018) were published, evidence from the 2018 CHOCOLATE RCT supported early cholecystectomy for acute cholecystitis (AC), even in high-risk patients. This study aims to investigate AC management at our tertiary care center in the years following these publications., Methods: A retrospective cohort study was performed on patients admitted from 2018 to 2023. AC severity was graded using TG2018 definitions. Comorbidities were summarized using Charlson Comorbidity Index (CCI) and frailty using the 5-item modified Frailty Index (5mFI). Compliance with TG2018 recommendations for management strategy was investigated. Outcomes were compared between patients who underwent surgery versus non-operative management (NOM). Subset analysis based on patients' age, frailty, and comorbidities was performed., Results: Among 642 AC patients, 57% underwent cholecystectomy and 43% NOM (22% percutaneous cholecystostomy, 21% antibiotics only). NOM patients had greater length of stay (LOS), complications, deaths, readmissions, and discharge to nursing/rehab versus surgery patients. In 70% of patients managed non-operatively, TG2018 were not followed. Patients managed non-operatively despite TG2018 were more likely to undergo delayed cholecystectomy compared to those in whom guidelines were followed (17% vs. 4%). In subset analysis, healthy octogenarians were significantly less likely to be managed according to TG2018 (9.4%); patients undergoing surgery had a trend towards shorter LOS (3.1 vs. 4.8 days) than those managed non-operatively but no difference in other outcomes., Conclusion: Most patients undergoing NOM could potentially undergo cholecystectomy if guidelines are considered. A more objective approach to risk assessment may optimize patient selection and outcomes., (© 2024. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Background: Heart failure is a clinical syndrome characterized by decreased cardiac output, leading to systemic organ hypoxia and resulting in dyspnea, pulmonary edema, organ congestion, and pleural effusion. Owing to the diverse clinical manifestations of heart failure, early diagnosis can be challenging, and misdiagnosis may occur occasionally. The use of echocardiography and blood brain natriuretic peptide can aid in obtaining a more accurate diagnosis., Case Presentation: This article presents two case reports of patients who were misdiagnosed with acute cholecystitis. Both patients were young Mongolia males (age 26 and 39 years) who presented to the emergency department with acute upper abdominal pain, abdominal ultrasound revealed gallbladder enlargement, and blood tests suggested mild elevation of bilirubin levels. However, despite the absence of procalcitonin and C-reactive protein elevation, the patients were admitted to the general surgical department with a diagnosis of "acute cholecystitis." Both patients were given treatment for cholecystitis, but their vital signs did not improve, while later examinations confirmed heart failure. After treatment with diuretics and cardiac glycosides, both patients' symptoms were relieved., Conclusion: We aim to highlight the clinical manifestations of heart failure and differentiate it from rare conditions such as acute cholecystitis. Physicians should make accurate diagnoses on the basis of physical examinations, laboratory testing and imaging, and surveys while avoiding diagnostic heuristics or mindsets. By sharing these two case reports, we hope to increase awareness to prevent potential complications and improve patient outcomes., (© 2024. The Author(s).)

Background: There has been a progressive increase in the use of percutaneous cholecystostomy (PC) in acute cholecystitis (AC) over the last decades due to population aging, and the support of guidelines (Tokyo Guidelines (TG), World Society of Emergency Surgery (WSES) Guidelines) as a valid therapeutical option. However, there are many unanswered questions about the management of PCs. An international consensus on indications and PC management using Delphi methodology with contributions from experts from three surgical societies (EAHPBA, ANS, WSES) have been performed., Methods: A two-round Delphi consensus, which included 27 questions, was sent to key opinion leaders in AC. Participants were asked to indicate their 'agreement/disagreement' using a 5-point Likert scale. Survey items with less than 70% consensus were excluded from the second round. For inclusion in the final recommendations, each survey item had to have reached a group consensus (≥ 70% agreement) by the end of the two survey rounds., Results: 54 completed both rounds (82% of invitees). Six questions got > 70% and are included in consensus recommendations: In patients with acute cholecystitis, when there is a clear indication of PC, it is not necessary to wait 48 h to be carried out; Surgery is the first therapeutic option for the TG grade II acute cholecystitis in a patient suitable for surgery; Before PC removal a cholangiography should be done; There is no indication for PC in Tokyo Guidelines (TG) grade I patients; Transhepatic approach is the route of choice for PC; and after PC, laparoscopic cholecystectomy is the preferred approach (93.1%)., Conclusions: Only six statements about PC management after AC got an international consensus. An international guideline about the management of PCs are necessary., (© 2024. The Author(s).)

Background: We aim to investigate the impact of routine cholangiography on asymptomatic patients with percutaneous cholecystostomy (PCC) for acute cholecystitis (AC)., Methods: The study included all patients treated with PCC for AC from 2017 to 2020 ​at a single academic center. Patients who underwent routine cholangiography within 30 days post-discharge while asymptomatic were compared to patients who were only followed clinically., Results: The groups (cholangiography group, n ​= ​44, and control group, n ​= ​145) were similar in terms of age, comorbidities, and clinical presentation. The readmission rate for biliary disease in the cholangiography group was nearly half that of the control group (22.7 ​% vs. 40.7 ​%, p ​= ​0.05) over an average follow-up of 10.4 months. The time to drain removal, cholecystectomy rate, and time to operation were comparable between the groups (42 vs. 40 days, p ​= ​0.47, 52.3 ​% vs 53.1 ​%, p ​= ​NS and 69 vs. 82 days, p ​= ​0.17, respectively)., Conclusions: Routine cholangiography can help reduce biliary disease readmissions among asymptomatic patients with PCC for AC without delaying further treatment., Competing Interests: Declaration of competing interest The authors have no related conflicts of interest to declare., (Copyright © 2024 Elsevier Inc.

Introduction: Acute cholecystitis occurs frequently in the elderly. According to the current recommendations specific to the characteristics of each case, these patients are most often treated by delayed cholecystectomy after medical treatment. Our study aimed to compare the success rate of this strategy in patients over and under 75years of age., Patients and Methods: This was a retrospective single-center analytic observational study that included patients who were hospitalized for acute cholecystitis in a geriatric postoperative unit (unité postopératoire gériatrique [UPOG]) and gastrointestinal surgery unit between 2021 and 2022. The main endpoint was the failure rate of deferred cholecystectomy. Secondary endpoints included: respect for the recommended operative delay, loss of the patient's functional independence during hospitalization, and the reason for surgical abstention., Results: In total, 290 patients were included. The strategy of delayed elective cholecystectomy was not achieved in 31 (44%) patients 75years old or older vs. eight (18%) patients younger than 75years old (P=0.005). The main reason was the decision not to operate after medical treatment. In both groups, the recommended operative interval was equitably respected and the loss of autonomy during hospitalization was minor. More than one-third of the elderly patients scheduled for elective surgery finally refused to undergo surgery., Conclusion: The strategy of routine elective cholecystectomy should not be strict in the elderly with acute cholecystitis; the indication for this procedure should take into account the wishes as well as the physiological status of the patient., (Copyright © 2024 Elsevier Masson SAS.

Background: Bile duct injury (BDI) is one of the most severe complications during cholecystectomy. Early identification of risk factors for BDI may permit risk reduction strategies and inform patient consent. Objective: This study aimed to define patient, provider, and systemic factors associated with BDI; BDI incidence; and short-term outcomes of BDI after urgent cholecystectomy. Methods: Patients who underwent urgent cholecystectomy for acute cholecystitis were retrospectively screened (2020-2022). All patients who sustained BDI were included without exclusions. Demographics, clinical data, and outcomes were collected and compared with descriptive statistics. Results: During the study period, BDI occurred in 4 (0.5%) of 728 patients who underwent urgent cholecystectomy for acute cholecystitis. Most BDI cases (75%) took place overnight or during the weekend. The attending surgeon was almost exclusively (75%) in their first year of practice. BDI was recognized during index operation in 2 cases (50%). Hepatobiliary surgery performed the bile duct repair in all 4 cases. Two complications occurred (50%). All patients were followed by hepatobiliary surgery in the outpatient setting and returned to their baseline level of function within 2 months of hospital discharge. Conclusion: Most BDI occurred in procedures attended by first-year faculty during after hours cholecystectomies, suggesting a role for increased proctorship in early career attendings in addition to in-hours cholecystectomy for acute cholecystitis. The timely return to baseline function experienced by these patients emphasizes the favorable outcomes associated with early recognition of BDI and involvement of hepatobiliary surgery. Further examination with multicenter evaluation would be beneficial to validate these study findings., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Patients with acute cholecystitis (AC) presenting with unfavorable systemic or local conditions are often managed with percutaneous cholecystostomy (PC) as a temporary measure. The clinical outcomes of interval cholecystectomy following PC remain unclear. The aim of the study was to identify the association between the timing of cholecystectomy following PC for AC and perioperative complication rates at interval cholecystectomy. We hypothesized that there would be a specific time interval to cholecystectomy associated with lower risk for adverse events., Methods: This was a retrospective (2018-2020) multicenter study at 8 participating hospital systems of adult patients with AC, managed with PC and interval cholecystectomy. Demographics, comorbidities, treatment details, and outcomes were examined. Patients were grouped based on quartiles for timing of surgery after PC (< 7, 7-9, 10-13, > 13 weeks). The primary outcome was a composite endpoint of bile duct injury, reoperation, readmission, image-guided intervention, endoscopic intervention, conversion to open surgery, or death., Results: There were 188 patients with a median age of 66 years with AC classified as mild (41%), moderate (47%), and severe (12%). Median days from PC to surgery were 65 (Q1 = 48, Q3 = 91). Laparoscopic cholecystectomy (89.9%) was the most commonly planned approach (robotic 6.4%, 3.7% open) and 28 (14.9%) were converted to open. The composite endpoint was reported in 51 patients (27.1%). A biliary injury occurred in 7 (3.7%) patients. Time to surgery and intraoperative drain placement were independently associated with the composite outcome. Cholecystectomy within 7 weeks of PC was associated with decreased risk (OR = 0.36, 95% CI 0.13-0.97) of the composite endpoint, compared to patients undergoing surgery > 13 weeks after PC., Conclusion: Timing of surgery following PC was associated with procedural outcomes. Patients undergoing surgery before 7 weeks experienced significantly less morbidity than patients having delayed cholecystectomy. These results should be considered in patient selection and management after PC., (© 2024. The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.)

Acute cholecystitis (AC) is a prevalent surgical emergency, particularly among elderly individuals who present with high perioperative risks. While early cholecystectomy (CCY) is the standard treatment, percutaneous cholecystostomy (PC) is proposed as an alternative for high-risk patients. This systematic review aims to evaluate the comparative safety and efficacy of CCY versus PC in managing AC among elderly and high-risk surgical patients. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive search was conducted across multiple electronic databases, including PubMed/Medline, Cochrane Central Register of Controlled Trials (CENTRAL), ScienceDirect, Europe PMC, ClinicalTrials.gov, and EBSCO Open Dissertations, from July 1 to 15, 2024. Studies published from January 2019 to July 15, 2024, were included if they focused on patients aged 65 and older or those classified as high-risk surgical candidates. The review encompassed 72,366 participants across 22 studies, predominantly observational. Key outcomes assessed included postoperative complications, readmission rates, recurrence of cholecystitis, and mortality rates. This study highlights the need for individualized treatment strategies for managing AC in elderly populations. While CCY remains the preferred approach when feasible, PC offers a critical alternative for high-risk patients. Future research is necessary to optimize outcomes for this vulnerable population., Competing Interests: Conflicts of interest: In compliance with the ICMJE uniform disclosure form, all authors declare the following: Payment/services info: All authors have declared that no financial support was received from any organization for the submitted work.

Background: The 2018 Tokyo Guidelines (TG18) are used to classify the severity of acute cholecystitis (AC) but insufficient to predict the length of hospital stay (LOS). Methods: For patients with AC, clinical factors and computed tomography features, including our proposed grading system of pericholecystic fat stranding were used for predicting an LOS of ≥7 days in the logistic regression models. Results: Our multivariable model showed age ≥ 65 years (OR: 2.56, p < 0.001), C-reactive protein (CRP) ≥ 2 mg/dL (OR: 1.97, p = 0.013), gamma-glutamyltransferase levels (OR: 2.460, p = 0.001), TG18 grade (OR: 2.89 per grade, p < 0.001), and moderate to severe pericholecystic fat stranding (OR: 2.14, p = 0.012) exhibited prolonged LOS ≥ 7 days. Conclusions: We developed a scoring model, including TG18 grades (score of 1-3 per grade), our grading system of fat stranding (score of 1), CRP (score of 1), and gamma-glutamyltransferase (score of 1), and a cutoff of >3 had highest diagnostic performance.

Rationale and Objectives: In this preliminary study, we aimed to develop a deep learning model using ultrasound single view cines that distinguishes between imaging of normal gallbladder, non-urgent cholelithiasis, and acute calculous cholecystitis requiring urgent intervention., Methods: Adult patients presenting to the emergency department between 2017-2022 with right-upper-quadrant pain were screened, and ultrasound single view cines of normal imaging, non-urgent cholelithiasis, and acute cholecystitis were included based on final clinical diagnosis. Longitudinal-view cines were de-identified and gallbladder pathology was annotated for model training. Cines were randomly sorted into training (70%), validation (10%), and testing (20%) sets and divided into 12-frame segments. The deep learning model classified cines as normal (all segments normal), cholelithiasis (normal and non-urgent cholelithiasis segments), and acute cholecystitis (any cholecystitis segment present)., Results: A total of 186 patients with 266 cines were identified: Normal imaging (52 patients; 104 cines), non-urgent cholelithiasis (73;88), and acute cholecystitis (61;74). The model achieved a 91% accuracy for Normal vs. Abnormal imaging and an 82% accuracy for Urgent (acute cholecystitis) vs. Non-urgent (cholelithiasis or normal imaging). Furthermore, the model identified abnormal from normal imaging with 100% specificity, with no false positive results., Conclusion: Our deep learning model, using only readily obtained single-view cines, exhibited a high degree of accuracy and specificity in discriminating between non-urgent imaging and acute cholecystitis requiring urgent intervention., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Background: Gallbladder cysts are rare diseases with very few reported cases, and no clinical or histological definition has been established. Furthermore, cases of giant cysts outside the gallbladder wall are extremely rare. We report a rare case of giant gallbladder cyst with acute cholecystitis., Case Presentation: An 85-year-old woman with appetite loss and right lower abdominal pain lasting 2 days presented to our hospital. At first, the patient's abdominal pain was mild to moderate with no fever. Blood tests revealed a white blood cell count of 10,950/mm 3 , and the C-reactive protein (CRP) level was 14.35 mg/dl. A contrast-enhanced computed tomography (CT) scan of the abdomen revealed a grossly distended gallbladder (14.5 × 14.5 × 8.7 cm) with an incarcerated stone in the cystic duct. The patient was treated by percutaneous transhepatic gallbladder drainage (PTGBD) with 735 ml of drainage fluid. Oral contrast magnetic resonance cholangiopancreatography (MRCP) revealed that gallbladder swelling remained (14.0 × 6.5 cm) 3 days after PTGBD. We performed laparoscopic cholecystectomy 6 days after PTGBD. Because of the severe adhesion around the junction of the cystic and common bile ducts, we performed open cholecystectomy. The resected specimen was 14 × 11 cm in size and consisted of a gallbladder (6 × 7 cm) with a stone (2.4 × 1.8 cm) in the gallbladder and a large cystic lesion (18 × 18 cm) outside the gallbladder wall. The cystic lesion had a wall thickness of 6 to 12 mm and internal septal structures and contained hemorrhagic and necrotic tissue. Histological examination revealed that the specimens showed a mildly swollen gallbladder and a cystic lesion on the outside of the gallbladder wall, adjacent to the gallbladder wall, with wall thickening and inflammation. The cystic lesion suggested gallbladder duplication, gallbladder diverticulum or extension of the Rokitansky-Aschoff sinus (RAS). There was no malignancy. The patient's postoperative course was uneventful, and she was discharged 5 days after the operation., Conclusion: We present a very rare case of giant gallbladder cyst with acute cholecystitis revealed by cholecystectomy., (© 2024.

We report the isolation of Helicobacter cholecystus from a positive blood culture of a 58-year-old male with bacteremia and acute cholecystitis, in China. The patient's condition improved after symptomatic support treatment and subtotal cholecystectomy. This suggests that H. cholecystus should be considered a potential human pathogen.

Postoperative delirium (POD) is one of the most common complications of surgery. This study aimed to identify the risk factors for POD in patients undergoing cholecystectomy for acute cholecystitis. This retrospective study included 77 patients who underwent cholecystectomy for acute cholecystitis between January 2015, and December 2020. Multiple logistic regression analysis was used to identify the factors associated with the development of delirium as the primary endpoint. Patients were divided into POD (n = 18) and non-POD (n = 59) groups and their demographic features and clinical results were compared. A significant model associated with delirium onset was predicted (Nagelkerke's R 2  = 0.382), and the significantly correlated factors were C-reactive protein/albumin ratio (CAR), Subjective Global Assessment (SGA) score, and history of psychiatric disease. The predictive value of CAR for POD was evaluated using ROC analysis; the area under the curve of CAR was 0.731, with a cutoff value of 3.69. CAR, SGA score, and a history of psychiatric disease were identified as factors associated with the development of POD in patients with acute cholecystitis. In particular, the new preoperative evaluation of CAR may be beneficial as an assessment measure of the risk factor for the development of POD., (© 2024. The Author(s).)

Background: Minimally invasive (MIS) cholecystectomies have become standard due to patient and hospital advantages; however, this approach is not always achievable. Acute and gangrenous cholecystitis increase the likelihood of conversion from MIS to open cholecystectomy. This study aims to examine patient and hospital factors underlying differential utilization of MIS vs open cholecystectomies indicated for acute cholecystitis., Methods: This is a retrospective, observational cohort study of patients with acute cholecystitis who underwent a cholecystectomy between 2016 and 2018 identified from the California Office of Statewide Health Planning and Development database. Univariate analysis and multivariable logistic regression models were used to analyze patient, geographic, and hospital variables as well as surgical approach., Results: Our total cohort included 53,503 patients of which 98.4% (n = 52,673) underwent an initial minimally invasive approach and with a conversion rate of 3.3% (n = 1,759). On multivariable analysis advancing age increased the likelihood of either primary open (age 40 to < 65 aOR 2.17; ≥ 65 aOR 3.00) or conversion to open cholecystectomy (age 40 to < 65 aOR 2.20; ≥ 65 aOR 3.15). Similarly, male sex had higher odds of either primary open (aOR 1.70) or conversion to open cholecystectomy (aOR 1.84). Hospital characteristics increasing the likelihood of either primary open or conversion to open cholecystectomy included teaching hospitals (aOR 1.37 and 1.28, respectively) and safety-net hospitals (aOR 1.46 and 1.33, respectively)., Conclusions: With respect to cholecystectomy, it is well-established that a minimally invasive surgical approach is associated with superior patient outcomes. Our study focused on the diagnosis of acute cholecystitis and identified increasing age as well as male sex as significant factors associated with open surgery. Teaching and safety-net hospital status were also associated with differential utilization of open, conversion-to-open, and MIS. These findings suggest the potential to create and apply strategies to further minimize open surgery in the setting of acute cholecystitis., (© 2024.

Purpose: The severity of surrounding adhesions, anomalous anatomy, and technical issues are the main factors that complicate cholecystectomy. This study focused on determining the types and frequency of laparoscopic anatomical variations found during laparoscopic cholecystectomy in our limited-resources condition and on defining the safe zone of dissection., Methods: This prospective study was conducted at a single center in Aden, Yemen from 2012 to 2019. A total of 375 patients, comprising 355 females (94.7%) and 20 males (5.3%), presented with symptomatic gallbladders and underwent standard four-port laparoscopic cholecystectomy. The regional laparoscopic variations were evaluated and recorded., Results: Of the 375 patients, 26 (6.9%) had laparoscopic anatomical variations, of whom 19 (73.1%) had vascular variations and seven (26.9%) had ductal variations. The anatomical variations included the following: double cystic artery of separated origin, seven cases (26.9%); Moynihan's hump, six (23.1%); double cystic artery of single origin, four (15.4%); thin long cystic duct, four (15.4%); subvesical duct, three (11.5%); and cystic artery hocking the cystic duct, two (7.7%)., Conclusion: Biliary anatomical variations can be expected in any dissected zone. Most of the detected variants were associated with the cystic artery. An overlooked accessory cysto-biliary communication can cause complicated biliary leakage. A surgeon's skills and knowledge of laparoscopic anatomical variants are essential for performing a safe laparoscopic cholecystectomy.

Background: Laparoscopic cholecystectomy (LC) is the preferred treatment for acute cholecystitis (AC). However, the optimal timing for LC in AC management remains uncertain, with early cholecystectomy (EC) and interval cholecystectomy (IC) being two common approaches influenced by various factors., Methods: This retrospective study, conducted at a tertiary care teaching hospital in Karachi, Pakistan, aimed to compare the outcomes of EC vs. IC for AC management. Patient data from January 2019 to September 2019 were analyzed with a focus on operative complications, duration of surgery, and postoperative hospital stay. The inclusion criteria were based on the Tokyo Guidelines, and patients underwent LC within 3 days of symptom onset in the EC group and after 6 weeks in the IC group., Results: Among 147 eligible patients, 100 underwent LC (50 in each group). No significant differences were observed in the sex distribution or mean age between the two groups. The EC group experienced fewer operative complications (12%) than the IC group (34%), with statistically significant differences observed. Nevertheless, no substantial variations in operative time or postoperative hospital stay were observed between the groups., Conclusion: Reduced complications in the EC group underscore its safety and efficacy. Nonetheless, further validation through multicenter studies is essential to substantiate these findings., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024 Raja, Ali, Kumar, Raja, Samo and Memon.)

Introduction: Biliary hamartomas are rare congenital development anomaly of bile ducts, which are detected incidentally. They often present as multiple lesions on liver surface which resembles metastatic lesions. We report a case of acute calculous cholecystitis ultimately diagnosed to have asymptomatic multiple biliary hamartomas., Case Description: A 42-year-old male with no co-morbidities presented with pain in upper abdomen associated with fever and vomiting. Contrast enhanced computed tomography (CECT) of abdomen showed acute calculous cholecystitis, hepatomegaly with fatty changes in liver. On laparoscopy the liver was found to have grey-white nodular lesions of about 0.5 cm in diameter scattered on the surface of both the lobes. One of the lesion was biopsied along with cholecystectomy., Discussion: Biliary hamartoma commonly referred to as "von Meyenburg complexes" are uncommon lesions found in the liver which are usually asymptomatic. In this case the patient presented with symptoms of acute cholecystitis but the biopsy report from liver lesions proved to be benign biliary hamartoma which on initial impression looked like multiple liver secondaries., Conclusion: We have described a case of an adult with multiple biliary hamartoma which was an incidental finding. Biliary hamartoma is a rare entity which can sometime mimic metastasis in the liver. Thus, histopathological confirmation is essential before planning any further treatment., Competing Interests: Declaration of competing interest Dr. Deepika C.A declares no conflict of interest in this study.

Introduction: Substantial evidence exists for the superiority of emergency over delayed cholecystectomy for gallstone disease during primary admission. Despite this, emergency surgery rates in the UK remain low compared with other developed countries, with great variation in care across the nation. We aimed to describe the local paradigm shift towards emergency surgery and investigate outcomes., Methods: This is a prospective observational study examining patients enrolled onto an emergency cholecystectomy pathway, following the hospital's subscription to the Royal College of Surgeons of England's Cholecystectomy Quality Improvement Collaborative (Chole-QuIC), between 1 December 2021 and 31 January 2023. Multivariate logistical regression models were used to identify patient and hospital factors associated with postoperative outcomes., Results: Of the 307 suitable acute admissions, 261 (85%) had an emergency cholecystectomy, compared with 5% preceding the Chole-QuIC interventions. Waiting time dropped from 67 to 5 days. A total of 208 (79.7%) patients were primary presentations, 92 (35.2%) were classed Tokyo grade 2 and 142 (54.4%) were obese. A total of 23 (8.8%) patients underwent preoperative endoscopic retrograde cholangiopancreatography, and 26 (10%) patients had a subtotal cholecystectomy. Favourable outcomes (Clavien Dindo ≥3) were observed in first presentations (odds ratio (OR) 0.35; p =0.042) and for operation times within 7 days (OR 0.32; p =0.037), with worse outcomes in BMI ≥35 (OR 3.32; p =0.005) and operation time >7 days (OR 3.11; p =0.037)., Conclusion: A paradigm shift towards emergency cholecystectomy benefits both the patient and the service. Positive outcomes are apparent for early operation in patients presenting for the first time and recurrent attendees, with early operation (<7 days) providing the most favourable outcome in a select patient group.

Background: Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) offers a safe and minimally invasive alternative for percutaneous cholecystostomy (PCC) in acute cholecystitis patients with high-surgical risk. Additionally, EUS-GBD serves as a rescue biliary drainage in malignant distal biliary obstruction. Despite its widespread application, data within the Indian context remains sparse. This study aims to report the outcomes of EUS-GBD through the first multi-center study from India., Methods: We retrospectively analyzed patients undergoing EUS-GBD at six tertiary care centers of India from March 2022 to November 2023. EUS-GBD was performed by free hand or over-the-guidewire technique with lumen-apposing metal stent (LAMS) or large caliber metal stent (LCMS). The primary outcome was technical success (defined as successful deployment of stent between gallbladder and stomach/duodenal lumen). The secondary outcomes were clinical success (defined as resolution of symptoms of acute cholecystitis and more than > 50% reduction in bilirubin level within two weeks in distal biliary obstruction), adverse event rate, 30-day mortality rate and 90-day reintervention rate., Results: Total 29 patients (mean age 65.86 ± 12.91, 11 female) underwent EUS-GBD. The indication for EUS-GBD were acute cholecystitis (79.31%) and rescue biliary drainage for malignant distal biliary obstruction (20.69%). LAMS was deployed in 92.86%, predominantly by free-hand technique (78.57%). Technical and clinical success rates were 96.55% and 82.75%, respectively. Adverse events occurred in 27.59% patients, with severe adverse events (bile leak and bleeding) being uncommon (10%). Both 30-day mortality rate and 90-day reintervention rate were 13.79% in patients. Cholecysto-duodenal fistula facilitated cholecystoscopic intervention and stone removal in one patient and transgastric EUS-GBD did not hamper bilio-enteric anastomosis during Whipple surgery in two patients., Conclusion: EUS-GBD is a safe and effective technique for managing acute cholecystitis in high-risk patients and for biliary drainage in cases with malignant distal biliary obstruction., (© 2024.

In patients considered high risk of laparoscopic cholecystectomy, percutaneous gallbladder drainage is traditionally considered first-line treatment option. Recent evidence supports endoscopic gallbladder drainage as a safe and feasible alternate option. We describe a case of Roux-en-Y gastric bypass surgery patient with acute cholecystitis and choledocholithiasis with unsuccessful laparoscopic cholecystectomy because of difficult operative field, underwent successful single-session endoscopic ultrasound-directed transgastric endoscopic retrograde cholangiopancreatography and endoscopic ultrasound-guided transmural gallbladder drainage at our institution., (© 2024 The Author(s).

Background: A critical view of safety (CVS) is important to ensure safe laparoscopic cholecystectomy. When the CVS is not possible, subtotal cholecystectomy is performed. While considering subtotal cholecystectomy, surgeons are often concerned about preventing bile leakage from the cystic ducts. The two main types of subtotal cholecystectomy for acute cholecystitis are fenestrating and reconstituting. Previously, there were no selection criteria for these two; therefore, open conversion was performed. This study aimed to evaluate our goal-oriented approach to choose fenestrating or reconstituting subtotal cholecystectomy for acute cholecystitis., Methods: We introduced our goal-oriented approach in April 2019. Before introducing this approach, laparoscopic cholecystectomy for acute cholecystitis was performed without criteria for subtotal cholecystectomy. After our approach was introduced, laparoscopic cholecystectomy for acute cholecystitis was performed according to the subtotal cholecystectomy criteria. We retrospectively reviewed the medical records of patients who underwent laparoscopic cholecystectomy for acute cholecystitis between 2015 and 2021. Laparoscopic cholecystectomy for acute cholecystitis was performed by surgeons regardless of whether they were novices or veterans., Results: The period from April 2015 to March 2019 was before the introduction (BI) of our approach, the period from April 2019 to December 2021 was after the introduction (AI) of our approach. There were 177 and 186 patients with acute cholecystitis during the BI and AI periods, respectively. There were no significant differences between groups in terms of preoperative characteristics, operative time, and blood loss. No difference in the laparoscopic subtotal cholecystectomy rate between groups (10.2% [BI] vs. 13.9% [AI]; p = 0.266) was obserbed. The open conversion rate during the BI period was significantly higher than that during the AI period (7.4% vs. 1.6%; p = 0.015)., Conclusions: Our goal-oriented approach is feasible, safe, and easy for many surgeons to understand., (© 2024.

Introduction Surgeons-in-training (SIT) perform laparoscopic cholecystectomy (LC); however, it is challenging to complete the procedure safely in difficult cases. We present a surgical technique during difficult LC, which we named the hanging strap method. Methods We retrospectively compared the perioperative outcomes between patients undergoing difficult LC with the hanging strap method (HANGS, n = 34), and patients undergoing difficult LC without the hanging strap method (non-HANGS, n = 56) from 2022 and 2024. Difficult LC was defined as cases classified as more than grade II cholecystitis by the Tokyo Guidelines 18 and cases when LC was undergoing over five days after the onset of cholecystitis. Results The proportion of SIT with post-graduate year (PGY) ≤ 7 was significantly higher in the HANGS group than in the non-HANGS group (82.4% vs. 33.9%, P < 0.001). The overall rate of bile duct injury (BDI), postoperative bile leakage and operative mortality were zero in the whole cohort. There were no significant differences between the HANGS and non-HANGS groups in background characteristics, operative time (122 min vs. 132 min, P = 0.830) and surgical blood loss (14 mL vs. 24 mL, P = 0.533). Conclusions Our findings suggested that the hanging strap method is safe and easy to use for difficult LC. We recommend that the current method be selected as one of the surgical techniques for SIT when performing difficult LC., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Background: Laparoscopic cholecystectomy (LC) is required for acute cholecystitis patient with percutaneous transhepatic gallbladder drainage (PTGBD). However, it's unknown how to distinguishing the surgical difficulty for these patients., Methods: Data of patients who underwent LC after PTGBD between 2016 and 2022 were collected. Patients were categorized into difficult and non-difficult operations based on operative time, blood loss, and surgical conversion. Performance of prediction model was evaluated by ROC, calibration, and decision curves., Results: A total of 127 patients were analyzed, including 91 in non-difficult operation group and 36 in difficult operation group. Elevated CRP ( P  = 0.011), pericholecystic effusion ( P  < 0.001), and contact with stomach or duodenal ( P  = 0.015) were independent risk factors for difficult LC after PTGBD. A nomogram was developed according to these risk factors, and was well-calibrated and good at distinguishing difficult LC after PTGBD., Conclusion: Preoperative elevated systemic and local inflammation indictors are predictors for difficult LC after PTGBD., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

This case presentation involves a 31-year-old pregnant woman (gravida 2, para 1) in her 33rd week of pregnancy, who presented to the Emergency Department of General Hospital of Trikala, in Greece, complaining of 24-hour abdominal pain, vomiting, and diarrheal stools. With a possible initial diagnosis of acute gastroenteritis, it was decided to admit the pregnant woman to the Obstetrics and Gynecology Department. Abdominal ultrasound revealed thickening of the gallbladder wall without the presence of gallstones or distension of the intrahepatic and extrahepatic bile ducts. Clinical examination by a surgical team, combined with ultrasound and laboratory findings, established the diagnosis of acute cholecystitis. After successful conservative antibiotic treatment, the patient was discharged from the department on the fifth day of hospitalization. She underwent laparoscopic cholecystectomy during the puerperal period. In this paper, after describing a case of acute cholecystitis in pregnancy, we highlight the significant diagnostic difficulties and therapeutic dilemmas regarding the management of these patients, including their reluctance to use invasive diagnostic methods and their concerns about the teratogenicity of administered drugs., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Background: Emergency cholecystectomy is the mainstay in treating acute cholecystitis (AC). In actual practice, perioperative prophylactic antibiotics are used to prevent postoperative infectious complications (PIC), but their effectiveness lacks evidence. We aim to investigate the efficacy of prophylactic antibiotics in emergency cholecystectomy., Methods: We searched PubMed, Embase, Cochrane CENTRAL, Web of Science (WOS), and Scopus up to June 14, 2023. We included randomized controlled trials (RCTs) that involved patients diagnosed with mild to moderate AC according to Tokyo guidelines who were undergoing emergency cholecystectomy and were administered preoperative and/or postoperative antibiotics as an intervention group and compared to a placebo group. For dichotomous data, we applied the risk ratio (RR) and the 95% confidence interval (CI), while for continuous data, we used the mean difference (MD) and 95% CI., Results: We included seven RCTs encompassing a collective sample size of 1747 patients. Our analysis showed no significant differences regarding total PIC (RR = 0.84 with 95% CI (0.63, 1.12), P = 0.23), surgical site infection (RR = 0.79 with 95% CI (0.56, 1.12), P = 0.19), distant infections (RR = 1.01 with 95% CI (0.55, 1.88), P = 0.97), non-infectious complications (RR = 0.84 with 95% CI (0.64, 1.11), P = 0.22), mortality (RR = 0.34 with 95% CI (0.04, 3.23), P = 0.35), and readmission (RR = 0.69 with 95% CI (0.43, 1.11), P = 0.13)., Conclusion: Perioperative antibiotics in patients with mild to moderate acute cholecystitis did not show a significant reduction of postoperative infectious complications after emergency cholecystectomy.

Purpose: To formulate and evaluate the diagnostic performance and utility of a new CT difficulty score in predicting difficult laparoscopic surgery in cases of gallbladder (GB) perforation., Methods: This prospective single centre study included a total of 48 diagnosed cases of GB perforation on CT between December 2021 and June 2023, out of which 24 patients were operated. A new 6-point CT difficulty scoring system was devised to predict difficult laparoscopic approach, based on patterns of inflammation around the perforated GB that were found to be surgically relevant. The pre-operative imaging findings on CT were studied in detail and correlation coefficients of various imaging findings were calculated to predict difficult surgery., Results: On CECT, the type of perforation, according to the revised Niemeier's classification could be exactly delineated in all 48 patients. A CT difficulty score of ≥ 3 was found to a good predictor difficult laparoscopic approach, with statistical significance (p = 0.001), sensitivity of 94.44%, specificity of 83.33%, PPV of 94.44% and NPV of 83.33%. Inflammatory changes around duodenum showed maximum correlation coefficient of 0.744 (p = 0.0001), around colon showed a correlation coefficient of 0.657 (p = 0.0005), and in the omentum had a correlation coefficient of 0.5 (p = 0.013)). Inter-observer agreement was also calculated for various findings and it was found to have moderate to strong agreement (κ value 0.5-1.0)., Conclusion: The CT difficulty scoring system can be an effective tool in predicting difficult laparoscopic surgery in cases of GB perforation in an emergency setting which can help in decision making and improved patient outcome., (© 2024.

Introduction: Leptospirosis is a bacterium with a worldwide distribution and belongs to the group of zoonoses that can affect both humans and animals. Most cases of leptospirosis present as a mild, anicteric infection. However, a small percentage of cases develop Weil's disease, characterized by bleeding and elevated levels of bilirubin and liver enzymes. It can also cause inflammation of the gallbladder. Acute acalculous cholecystitis has been described as a manifestation of leptospirosis in a small percentage of cases; however, no association between leptospirosis and acute acalculous cholecystitis has been found in the literature., Case Presentation: In this report, we describe the case of a 66-year-old patient who presented to the emergency department with a clinical picture dominated by fever, an altered general condition, abdominal pain in the right hypochondrium, nausea, and repeated vomiting. Acute calculous cholecystitis was diagnosed based on clinical, laboratory, and imaging findings. During preoperative preparation, the patient exhibited signs of liver and renal failure with severe coagulation disorders. Obstructive jaundice was excluded after performing an abdominal ultrasound and computed tomography scan. The suspicion of leptospirosis was then raised, and appropriate treatment for the infection was initiated. The acute cholecystitis symptoms went into remission, and the patient had a favorable outcome. Surgery was postponed until the infection was treated entirely, and a re-evaluation of the patient's condition was conducted six-week later., Conclusions: The icterohemorrhagic form of leptospirosis, Weil's disease, can mimic acute cholecystitis, including the form with gallstones. Therefore, to ensure an accurate diagnosis, leptospirosis should be suspected if the patient has risk factors. However, the order of treatments is not strictly established and will depend on the clinical picture and the patient's prognosis., (© 2024 Renata Moriczi et al., published by Sciendo.)

Abdominal pain in patients with significant alcohol use and smoking history presents diagnostic challenges due to overlapping clinical features of complications like acute cholecystitis and peptic ulcers. The unreliable physical examinations of intoxicated patients often complicate accurate diagnosis. We present a case of a 56-year-old male with a history of alcoholism and smoking, who presented to the emergency department with nonspecific abdominal pain. Initial imaging suggested cholecystitis, but due to the patient's intoxication, his physical examination was unreliable. During a laparoscopic cholecystectomy, a perforated prepyloric ulcer was unexpectedly discovered, sealed by the gallbladder. This case highlights the limitations of relying solely on imaging for diagnosing abdominal conditions in intoxicated patients. The intraoperative discovery of the perforated ulcer necessitated a shift in the surgical approach, emphasizing the need for flexibility in surgical planning and a high index of suspicion for other abdominal pathologies in patients with significant lifestyle risks. The successful management of this patient through adaptive surgical techniques and comprehensive postoperative care, including Helicobacter pylori eradication therapy, underscores the importance of maintaining a broad differential diagnosis and readiness to adapt surgical plans. This approach is essential for managing complex cases effectively, ensuring that both the immediate surgical issues and underlying causes are addressed to optimize recovery and prevent recurrence., (Published by Elsevier Inc. on behalf of University of Washington.)

Small bowel diverticulosis is not a common disease entity; however, it is increasingly diagnosed and linked to various gastrointestinal complaints. Although rare, complications can occur and may sometimes require surgical or endoscopic intervention. Furthermore, suspecting and diagnosing duodenal diverticulosis (DD) can be challenging due to the variety of presenting signs and symptoms. Much of our current knowledge comes from case reports and series. This report aims to document a case of DD presenting with severe right upper quadrant pain mimicking the signs and symptoms of acute cholecystitis. It also reviews and summarizes the available literature on the clinical manifestations of DD, its diagnostic approach, treatment modalities, and possible complications encountered in the ED., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Biliary complications like cholelithiasis and choledocholithiasis are more common in bariatric surgery patients due to obesity and rapid weight loss. Patients with a body mass index > 40 face an eightfold risk of developing cholelithiasis. Post-bariatric surgery, especially after laparoscopic Roux-en-Y gastric bypass (LRYGB), 30% of patients develop biliary disease due to rapid weight loss. The aim of this review is to analyze the main biliary complications that occur after bariatric surgery and its management. A review of the literature was conducted mainly from 2010 up to 2023 with regard to biliary complications associated with bariatric patients in SciELO, PubMed, and MEDLINE. Patients undergoing LRYGB have a higher incidence (14.5%) of symptomatic calculi post-surgery compared to those undergoing laparoscopic sleeve gastrectomy at 4.1%. Key biliary complications within 6 to 12 months post-surgery include: Cholelithiasis: 36%; Biliary colic/dyskinesia: 3.86%; Acute cholecystitis: 0.98%-18.1%; Chronic cholecystitis: 70.2%; Choledocholithiasis: 0.2%-5.7% and Pancreatitis: 0.46%-9.4%. Surgeons need to be aware of these complications and consider surgical treatments based on patient symptoms to enhance their quality of life., Competing Interests: Conflict-of-interest statement: The authors have no conflict of interest to declare., (©The Author(s) 2024.

Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) has emerged as a popular alternative to percutaneous cholecystostomy and endoscopic transpapillary gallbladder drainage for patients suffering from acute calculous cholecystitis who are at high risk for surgery. Multiple cohorts, meta-analyses, and a randomized controlled trial have shown that EUS-GBD has lower rates of recurrent cholecystitis and unplanned reinterventions, while achieving similar technical and clinical success rates than transpapillary cystic duct stenting. The essential steps, precautions in performing EUS-GBD and long-term management will be discussed in this article., Competing Interests: Disclosure Prof. A.Y.B.

Background: The impact of different phases of COVID-19 infection on outcomes from acute calculous cholecystitis (ACC) is not well understood. Therefore, we examined outcomes of acute cholecystitis during the COVID-19 pandemic, comparing the effect of different treatment modalities and COVID-19 infection status. We hypothesized that patients with acute COVID-19 would have worse outcomes than COVID-negative patients, but there would be no difference between COVID-negative and COVID-recovered patients., Methods: We used 2020-2023 National COVID Cohort Collaborative data to identify adults with ACC. Treatment (antibiotics-only, cholecystostomy tube, or cholecystectomy) and COVID-19 status (negative, active, or recovered) were collected. Treatment failure of nonoperative managements was noted. Adjusted analysis using a series of generalized linear models controlled for confounders (age, sex, body mass index, Charlson comorbidity index, severity at presentation, and year) to better assess differences in outcomes among treatment groups, as well as between COVID-19 groups., Results: In total, 32,433 patients (skewed count) were included: 29,749 COVID-negative, 2112 COVID-active, and 572 (skewed count) COVID-recovered. COVID-active had higher rates of sepsis at presentation. COVID-negative more often underwent cholecystectomy. Unadjusted, COVID-active had higher 30-day mortality, 30-day complication, and longer length of stay than COVID-negative and COVID-recovered. Adjusted analysis revealed cholecystectomy carried lower odds of mortality for COVID-active and COVID-negative patients than antibiotics or cholecystostomy. COVID-recovered patients' mortality was unaffected by treatment modality. Treatment failure from antibiotics was more common for COVID-negative patients., Conclusion: Acute cholecystitis outcomes are affected by phase of COVID-19 infection and treatment modality. Cholecystectomy does not lead to worse outcomes for COVID-active and COVID-recovered patients than nonoperative treatments; thus, these patients can be considered for cholecystectomy if their physiology is not prohibitive., (Published by Elsevier Inc.)

Acute cholecystitis is one of the most common surgical diseases, which may progress from mild to severe cases. When combined with bacteremia, the mortality rate of acute cholecystitis reaches up to 10-20%. The standard of care in patients with acute cholecystitis is early laparoscopic cholecystectomy. Percutaneous cholecystostomy or endoscopic procedures are alternative treatments in selective cases. Nevertheless, antibiotic therapy plays a key role in preventing surgical complications and limiting the systemic inflammatory response, especially in patients with moderate to severe cholecystitis. Patients with acute cholecystitis have a bile bacterial colonization rate of 35-60%. The most frequently isolated microorganisms are Escherichia coli , Klebsiella spp., Streptococcus spp., Enterococcus spp., and Clostridium spp. Early empirical antimicrobial therapy along with source control of infection is the cornerstone for a successful treatment. In these cases, the choice of antibiotic must be made considering some factors (e.g., the severity of the clinical manifestations, the onset of the infection if acquired in hospital or in the community, the penetration of the drug into the bile, and any drug resistance). Furthermore, therapy must be modified based on bile cultures in cases of severe cholecystitis. Antibiotic stewardship is the key to the correct management of bile-related infections. It is necessary to be aware of the appropriate therapeutic scheme and its precise duration. The appropriate use of antibiotic agents is crucial and should be integrated into good clinical practice and standards of care.

Shiga toxin-producing Escherichia coli-associated hemolytic uremic syndrome (STEC-HUS) can induce life-threatening complications, including acute kidney injury, encephalopathy, and gastrointestinal complications. On the other hand, there have been few reports of cholecystitis associated with STEC-HUS. In this study, we report the case of an 83-year-old Japanese man who developed recurrent acute cholecystitis associated with STEC-HUS. Prior to establishing a definite diagnosis of STEC-HUS, plasma exchange and hemodialysis were initiated, which resulted in a rapid increase in the platelet count and decrease in lactate dehydrogenase levels. The patient presented an enlarged gallbladder detected by computed tomography during the course of treatment. Due to recurrent flare-ups, the patient had to undergo several rounds of endoscopic retrograde biliary drainage and, ultimately, cholecystectomy to prevent relapse of acute cholecystitis. Since cholecystitis was thought to have been caused by complex mechanisms in this case, we discussed those from multiple perspectives. This case report highlights the need for particular care to be given to the management of pre-existing diseases as well as STEC-HUS, especially in older patients., (© 2023.

Purpose: This study investigates the efficacy of erector spinae plane block (ESPB) for managing perioperative and postoperative pain in patients undergoing percutaneous cholecystostomy (PC) for acute cholecystitis, particularly in high-risk elderly patients with extensive comorbidities and limited functional status., Methods: In a retrospective single-center study, 58 high-risk patients scheduled for PC were assessed. ESPB was administered to 23 patients, while 22 received conscious sedation. Pain intensity was measured using the numeric rating scale before any analgesic or ESPB administration, during the procedure and at 1 and 12 h post-procedure and secondary outcomes included adverse effects and additional analgesic requirements., Results: The ESPB group experienced significant pain reduction during and post-procedure compared to the conscious sedation group (p = 0.002). Procedure times were shorter (p = 0.015), and postoperative tramadol was less frequently needed in the ESPB group (p = 0.007). The incidence of nausea was also lower in the ESPB group (p = 0.001). No ESPB-related complications were reported., Conclusion: ESPB significantly alleviates perioperative and postoperative pain in PC patients, reducing additional analgesic use and side effects. It holds promise as a key component of pain management for high-risk surgical patients., Level of Evidence: Level 3, Non-randomized controlled cohort/follow-up study., (© 2024.

Background: Percutaneous cholecystostomy (PC) is a therapeutic intervention for acute cholecystitis. The benefits of cholecystostomy have been demonstrated in the medical literature, with up to 90% of acute cholecystitis cases shown to resolve postoperatively, and only 40% of patients subsequently undergoing an interval cholecystectomy., Purpose: To compare the survival outcomes between acute complicated and uncomplicated cholecystitis in patients undergoing PC as an initial intervention, as there is a paucity of evidence in the literature on this perspective., Material and Methods: A retrospective search was conducted of all patients who underwent PC for acute cholecystitis between August 2016 and December 2020 at a tertiary institution. A total of 100 patients were included in this study., Results: The outcome, in the form of 30-day mortality, 90-day mortality, being alive after six months, and reintervention, was compared between complicated and uncomplicated cases using the chi-square test or Fisher's exact test. There was no statistically significant difference in any of the compared outcomes. The only variable that showed a statistically significant association with the risk of mortality was acute kidney injury (AKI) at admission. Patients who had stage 1, 2, or 3 AKI had a higher hazard for mortality as compared to patients with no kidney disease., Conclusion: Our results demonstrate that PC is a safe and effective procedure. Mortality is not affected by the presence of complications. The results have, however, highlighted the importance of recognizing and treating AKI, an independent risk factor affecting mortality., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: The aim of this study was to investigate the efficacy of percutaneous cholecystostomy (PC) in the geriatric patients with acute cholecystitis., Materials and Methods: The records of geriatric patients with high surgical risk who underwent percutaneous cholecystostomy for acute cholecystitis were reviewed retrospectively., Results: The median age of 134 patients who underwent percutaneous cholecystostomy was 77 (65-98) years and 63.4% were women. The mean length of hospital stay was 5 (4-18) days, and the follow-up period until the procedure was 2 (1-6) days. Murphy's sign was positive in 79.1% of patients on physical examination, and the remaining patients (20.9%) had only tenderness on examination. As USG findings, 59.0% of the patients had a gall bladder wall thickness (> 4 mm) with pericholecystic fluid. Additional imaging method, abdominal CT, was performed in 29 patients (21.6%), MRCP was performed in three patients (2.2%), and ERCP was performed in one patient (0.7%). Bacterial growth was detected in 27.6% of the bile cultures performed. During the follow-up period, laparoscopic cholecystectomy was performed in 60.4% of the patients and open cholecystectomy was performed in 5.2% of the patients electively. 34.3% of the patients did not undergo any surgery. Bile leakage was detected in two patients (1.5%) as a procedure-related complication, and no mortality was observed., Conclusion: Abdominal ultrasonography-guided PC is a safe and effective method in the management of acute cholecystitis in high-risk patients in the geriatric age group., (© 2023.

Background & Aims: Endoscopic transpapillary gallbladder stenting (ETGS) has been proposed as one of the adjunctive treatments, apart from antibiotics, before surgery in patients with acute cholecystitis whose cholecystectomy could not be performed or was deferred. Currently, there are no comparative data on the outcomes of ETGS in those who receive and do not receive ETGS. We aimed to compare the rates of recurrent cholecystitis at 3 and 6 months in these 2 groups., Methods: Between 2020 and 2023, eligible acute calculous cholecystitis patients with a high probability of common bile duct stone, who were surgical candidates but could not have an early cholecystectomy during COVID-19 surgical lockdown, were randomized into groups A (received ETGS) and B (did not receive ETGS). A definitive cholecystectomy was performed at 3 months or later in both groups., Results: A total of 120 eligible patients were randomized into group A (n = 60) and group B (n = 60). In group A, technical and clinical success rates were 90% (54 of 60) and 100% (54 of 54), respectively. Based on intention-to-treat analysis, group A had a significantly lower rate of recurrence than group B at 3 months (0% [0 of 60] vs 18.3% [11 of 60]; P = .001). At 3-6 months, group A showed a nonsignificantly lower rate of recurrent cholecystitis compared to group B (0% [0 of 32] vs 10% [3 of 30]; P = .11)., Conclusions: ETGS could prevent recurrent cholecystitis in acute cholecystitis patients with common bile duct stone whose cholecystectomy was deferred for 3 months. In those who did not receive ETGS, the majority of recurrences occurred within 3 months. (Thaiclinicaltrials.org, Number TCTR20200913001)., (Copyright © 2024 AGA Institute. Published by Elsevier Inc.

Backgrounds/aims: The standard treatment for acute cholecystitis, biliary pancreatitis and intractable biliary colics ("hot gallbladder") is emergency laparoscopic cholecystectomy (LC). This paper aims to identify the prognostic factors and create statistical models to predict the outcomes of emergency LC for "hot gallbladder.", Methods: A prospective observational cohort study was conducted on 466 patients having an emergency LC in 17 months. Primary endpoint was "suboptimal treatment," defined as the use of escape strategies due to the impossibility to complete the LC. Secondary endpoints were postoperative morbidity and length of postoperative stay., Results: About 10% of patients had a "suboptimal treatment" predicted by age and low albumin. Postop morbidity was 17.2%, predicted by age, admission day, and male sex. Postoperative length of stay was correlated to age, low albumin, and delayed surgery., Conclusions: Several predictive prognostic factors were found to be related to poor emergency LC outcomes. These can be useful in the decision-making process and to inform patients of risks and benefits of an emergency vs. delayed LC for hot gallbladder.

Background: Acute cholecystitis (AC) is a common disease in general surgery. Laparoscopic cholecystectomy (LC) is widely recognized as the "gold standard" surgical procedure for treating AC. For low-risk patients without complications, LC is the recommended treatment plan, but there is still controversy regarding the treatment strategy for moderate AC patients, which relies more on the surgeon's experience and the medical platform of the visiting unit. Percutaneous transhepatic gallbladder puncture drainage (PTGBD) can effectively alleviate gallbladder inflammation, reduce gallbladder wall edema and adhesion around the gallbladder, and create a "time window" for elective surgery., Aim: To compare the clinical efficacy and safety of LC or PTGBD combined with LC for treating AC patients, providing a theoretical basis for choosing reasonable surgical methods for AC patients., Methods: In this study, we conducted a clinical investigation regarding the combined use of PTGBD tubes for the treatment of gastric cancer patients with AC. We performed searches in the following databases: PubMed, Web of Science, EMBASE, Cochrane Library, China National Knowledge Infrastructure, and Wanfang Database. The search encompassed literature published from the inception of these databases to the present. Subsequently, relevant data were extracted, and a meta-analysis was conducted using RevMan 5.3 software., Results: A comprehensive analysis was conducted, encompassing 24 studies involving a total of 2564 patients. These patients were categorized into two groups: 1371 in the LC group and 1193 in the PTGBD + LC group. The outcomes of the meta-analysis revealed noteworthy disparities between the PTGBD + LC group and the LC group in multiple dimensions: (1) Operative time: Mean difference (MD) = 17.51, 95%CI: 9.53-25.49, P < 0.01; (2) Conversion to open surgery rate: Odds ratio (OR) = 2.95, 95%CI: 1.90-4.58, P < 0.01; (3) Intraoperative bleeding loss: MD = 32.27, 95%CI: 23.03-41.50, P < 0.01; (4) Postoperative hospital stay: MD = 1.44, 95%CI: 0.14-2.73, P = 0.03; (5) Overall postoperative complication rate: OR = 1.88, 95%CI: 1.45-2.43, P < 0.01; (6) Bile duct injury: OR = 2.17, 95%CI: 1.30-3.64, P = 0.003; (7) Intra-abdominal hemorrhage: OR = 2.45, 95%CI: 1.06-5.64, P = 0.004; and (8) Wound infection: OR = 0. These findings consistently favored the PTGBD + LC group over the LC group. There were no significant differences in the total duration of hospitalization [MD = -1.85, 95%CI: -4.86-1.16, P = 0.23] or bile leakage [OR = 1.33, 95%CI: 0.81-2.18, P = 0.26] between the two groups., Conclusion: The combination of PTGBD tubes with LC for AC treatment demonstrated superior clinical efficacy and enhanced safety, suggesting its broader application value in clinical practice., Competing Interests: Conflict-of-interest statement: All the authors report no relevant conflicts of interest for this article., (©The Author(s) 2024.

Aim: The aim is to evaluate laparoscopic cholecystectomy safety based on American Society of Anesthesiologists score for acute cholecystitis in patients with comorbidities. Patients & methods: This is retrospective study of patients who underwent laparoscopic cholecystectomy for acute cholecystitis between 2003 and 2021. According to their respective ASA-score, patients were divided into group 1: ASA1-2 and group 2: ASA3-4. Results: We collected 578 patients. Even though the gangrenous forms were more frequent and the operative time was longer in group 2, laparoscopic cholecystectomy seems safe and effective. We didn't observe any differences in terms of intraoperative incidents, open conversion rate, or postoperative complications compared with other patients. Conclusion: ASA3-4 patients with acute cholecystitis don't face elevated risks of complications or mortality during laparoscopic cholecystectomy., Competing Interests: The authors have no competing interests or relevant affiliations with any organization or entity with the subject matter or materials discussed in the manuscript.

A rare disorder called situs inversus partialis (SIP) is characterized by the transposition of organs in the abdomen or thoracic cavity from one side of the body to the other (the mirror image of normal). Autosomal dominant, autosomal recessive, rare genetic mutations, and X-linked recessive inheritance patterns have been identified to be involved in this condition. Laparoscopic cholecystectomies have been successfully performed on patients with SIT. Due to challenges in spatial orientation and the identification of anatomical variations brought on by the abdominal organs' mirror image, surgery is more complicated and takes longer. We describe a 40-year-old female case who had acute cholecystitis. Laparoscopic cholecystectomy was used to treat this patient, a highly effective procedure for both the treatment and care of these patients. Post-surgical examination and follow-up revealed improvement in the patient's condition without subsequent complications., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Althunayan et al.)
