Background and Aims Despite advances in the medical treatment of Crohn's disease [CD], many patients will still need bowel resections and face the subsequent risk of recurrence and re-resection. We describe contemporary re-resection rates and identify disease-modifying factors and risk factors for re-resection. Methods We conducted a retrospective, population-based, individual patient-level data cohort study covering 47.4% of the Danish population, including all CD patients who underwent a primary resection between 2010 and 2020. Results Among 631 primary resected patients, 24.5% underwent a second resection, and 5.3% a third. Re-resection rates after 1, 5, and 10 years were 12.6%, 22.4%, and 32.2%, respectively. Reasons for additional resections were mainly disease activity [57%] and stoma reversal [40%]. Disease activity-driven re-resection rates after 1, 5, and 10 years were 3.6%, 10.1%, and 14.1%, respectively. Most stoma reversals occurred within 1 year [80%]. The median time to recurrence was 11.0 months. Biologics started within 1 year of the first resection revealed protective effect against re-resection for stenotic and penetrating phenotypes. Prophylactic biologic therapy at primary ileocaecal resection reduced disease recurrence and re-resection risk (hazard ratio [HR] 0.58, 95% confidence interval [CI] [0.34-0.99], p  = 0.047). Risk factors for re-resection were location of resected bowel segments at the primary resection, disease location, disease behaviour, smoking, and perianal disease. Conclusion Re-resection rates, categorised by disease activity, are lower than those reported in other studies and are closely associated with disease phenotype and localisation. Biologic therapy may be disease-modifying for certain subgroups when initiated within 1 year of resection. [ABSTRACT FROM AUTHOR]

Background: This report describes the oncologic outcomes for patients with advanced ovarian cancer who had bowel surgery performed by gynecologic oncologists (GOs) and compares the outcomes with those for bowel surgery performed by general surgeons (GSs) during maximal cytoreductive surgery. Methods: Patients from six academic institutions who had FIGO stage III or IV ovarian cancer and underwent any bowel surgeries during maximal cytoreductive surgery were eligible for the study. The patients were divided into two groups according to whether bowel surgery was performed by a GO or a GS. In both groups, the GOs were mainly involved in extra bowel debulking procedures. Perioperative and survival outcomes were compared between the two groups. Results: The 761 patients in this study included 113 patients who underwent bowel surgery by a GO and 648 who had bowel surgery by a GS. No discernible differences were observed in age, American Society of Anesthesiology (ASA) score, FIGO stage, histologic type, timing of cytoreductive surgery (primary or interval debulking surgery), or complications between the two groups. The GO group exhibited a shorter operation time than the GS group. Kaplan–Meier analysis showed no survival differences between the two groups. In the Cox analysis, non-serous cell types and gross residual diseases were associated with adverse effects on overall survival. However, performance of bowel surgery by a GO did not have an impact on survival. Conclusion: Performance of bowel surgery by a GO during maximal cytoreductive surgery is both feasible and safe. These results should be reflected in the training system for GOs regarding bowel surgery, and further research is needed to confirm that GOs can play a more leading role in performing extra-uterine procedures.

Pediatric short bowel syndrome (SBS) is a rare condition characterized by a massive loss of the small intestine, leading to the inability to meet nutritional requirements without the use of parenteral or enteral supplementation. SBS causes profound alterations in the intestinal microbiome and metabolome. The aim of this study was a detailed assessment of the intestinal microbiome and metabolome in a murine model of SBS. We performed a 60% proximal small bowel resection versus a sham operation in C57BL/6 mice. Four weeks postoperatively, the microbial communities of different intestinal segments (jejunum, ileum, colon) and stool were assessed by 16S rRNA gene sequencing. Bile acids in serum and stool and volatile organic compounds (VOCs) in the fecal headspace were assessed using LC-MS and GC-MS techniques. The α-diversity of the different intestinal segments did not significantly differ between the two groups. β-diversity significantly differed between sham and SBS mice. While in the jejunum, Faecalibaculum was significantly increased in SBS animals, a significant reduction in Lactobacillus and Sporosarcina was detected in the ileum of SBS mice. In the colon of SBS mice, a significant decrease in Ruminococcaceae and a significant increase in Proteobacteria such as Faecalibaculum and Escherichia-Shigella were found. Serum levels of deoxycholic, taurocholic and taurochenodeoxycholic acids were significantly higher in the SBS group. Of the 29 VOCs tested, hexane, isoflurane and pentane were significantly higher in the SBS group, and pyrrole was significantly lower. We were able to show that SBS causes shifts in the murine intestinal microbiome and metabolome including serum BAs and fecal VOCs.

Abdominal lipoblastoma is a rare tumor composed of embryonic fat. Mesenteric involvement is rarer, with only five cases reported in infants. We report a case of a 10-month-old infant with a lipomatous tumor arising from the ileal mesentery. Primary resection was done, and histopathology was suggestive of a lipoblastoma. The child is well in follow-up with no evidence of recurrence.

Background: Intestinal intussusception is the most common cause of intestinal obstruction in infants and children under 3 years of age. Any delay in diagnosis or management can lead to intestinal ischaemia and perforation. The aim of this study is to determine the sociodemographic and clinical risk factors associated with bowel resection in infants and children with intussusception. Materials and Methods: This is a retrospective analytical study of 118 patients operated at the Hassan II Hospital and University of Fez between 1 January 2008 and 1 January 2018. A comparison of risk factors between patients with and without bowel resection was performed using multivariate logistic regression. Results: One hundred and eighteen patients met the inclusion criteria. Of these, 44% had undergone bowel resection. Age >2 years (P = 0.006), duration of symptoms progression of more than 2 days (P = 0.002), bilious vomiting (P = 0.04) and palpation of an abdominal mass (P = 0.01) were significantly associated with bowel resection. Multivariate logistic regression showed that age

Aims: The aim is to investigate the effect of alvimopan on postoperative ileus and length of hospital stay in patients undergoing bowel resection. Methods: The PRISMA statement standards were followed to conduct a systematic review and meta-analysis. The available literature was searched to identify all studies comparing alvimopan with no alvimopan in patients undergoing bowel resection. Postoperative ileus and length of hospital stay were the primary outcomes, and time to first bowel motion was the secondary outcome. Random-effects modeling was applied for analyses. Results: Analysis of 94 833 patients from 26 studies showed that alvimopan was associated with lower risk of postoperative ileus (OR:.57, 95% CI.48 to.67, P <.00001; high GRADE certainty), shorter length of hospital stay (MD: −1.08 day, 95% CI −1.36 to −.81, P <.00001; moderate GRADE certainty), and shorter time to first bowel motion (MD: −.43 day, 95% CI −.58 to −.28, P <.00001; moderate GRADE certainty). Separate analyses of randomized controlled trials and observational studies showed similar findings. Subgroup analyses suggested consistent findings in patients undergoing elective bowel resection, emergency bowel resection, and open surgery; however, alvimopan did not improve the outcomes in patients undergoing minimally invasive surgery. Conclusion: Robust evidence supports the routine use of alvimopan in patients undergoing open bowel resection as indicated by lower risk of postoperative ileus and shorter length of hospital stay. We support incorporation of alvimopan into enhanced recovery after surgery programs for the procedures involving open bowel resection. The role of alvimopan in minimally invasive bowel resection needs more research. [ABSTRACT FROM AUTHOR]

Abstract Objectives To determine whether MRI can predict the necessity of rectosigmoid resection (RR) for optimal debulking surgery (ODS) in ovarian cancer (OC) patients and to compare the predictive accuracy of pre- and post-neoadjuvant chemotherapy (NACT) MRI. Methods The MRI of 82 OC were retrospectively analyzed, including six bowel signs (length, transverse axis, thickness, circumference, muscularis involvement, and submucosal edema) and four para-intestinal signs (vaginal, parametrial, ureteral, and sacro-recto-genital septum involvement). The parameters reflecting the degree of muscularis involvement were measured. Patients were divided into non-RR and RR groups based on the operation and postoperative outcomes. The independent predictors of the need for RR were identified by multivariate logistic regression analysis. Results Imaging for 82 patients was evaluated (67 without and 15 with NACT). Submucosal edema and muscularis involvement (OR 13.33 and 8.40, respectively) were independent predictors of the need for RR, with sensitivities of 83.3% and 94.4% and specificities of 93.9% and 81.6%, respectively. Among the parameters reflecting the degree of muscularis involvement, circumference ≥ 3/12 had the highest prediction accuracy, increasing the specificity from 81.6% for muscularis involvement only to 98.0%, with only a slight decrease in sensitivity (from 94.4% to 88.9%). The predictive sensitivities of pre-NACT and post-NACT MRI were 100.0% and 12.5%, respectively, and the specificities were 85.7% and 100.0%, respectively. Conclusions MRI analysis of rectosigmoid muscularis involvement and its circumference can help predict the necessity of RR in OC patients, and pre-NACT MRI may be more suitable for evaluation. Critical relevance statement We analyzed preoperative pelvic MRI in OC patients. Our findings suggest that MRI has predictive potential for identifying patients who require RR to achieve ODS. Key Points The need for RR must be determined to optimize treatment for OC patients. Muscularis involvement circumference ≥ 3/12 could help predict RR. Pre-NACT MRI may be superior to post-NACT MRI in predicting RR. Graphical Abstract

This study investigated the risk profile and the impact of dietary intervention in calcium oxalate stone formers with enteric hyperoxaluria under controlled, standardized conditions. Thirty-seven patients were included in the study. Dietary and 24-h urinary parameters were obtained on the self-selected diet and a balanced, standardized diet. Tests for [13C2]oxalate absorption, calcium- and ammonium chloride-loading were performed. Mean [13C2]oxalate absorption was 18.8%. A significant positive association was observed between urinary oxalate excretion and intestinal oxalate absorption. In addition, urinary oxalate excretion was significantly correlated with dietary oxalate intake. Mean urinary oxalate excretion decreased from 0.841 mmol/24 h on the usual diet to 0.662 mmol/24 h on the balanced diet, corresponding to a reduction of 21.3%. Besides hyperoxaluria, hypocitraturia and hypomagnesuria were the most common urinary abnormalities at baseline, being present in 83.8% and 81.1% of patients, respectively. Urinary citrate increased by 50.9% and magnesium excretion increased by 25.2% on the balanced diet. As a result, the relative supersaturation of calcium oxalate declined significantly (by 36.2%) on the balanced diet. Since 41% of patients on the balanced diet still had a urine volume of less than 2.0 L/24 h, efforts should be made to increase urine volume by increasing fluid intake and reducing intestinal fluid losses. Dietary intervention proved to be effective in reducing urinary oxalate excretion and should be a cornerstone of the treatment of patients with enteric hyperoxaluria. [ABSTRACT FROM AUTHOR]

Purpose: Kono-S anastomosis, an antimesenteric, functional, end-to-end handsewn anastomosis, was introduced in 2011. The aim of this meta-analysis is to evaluate the safety and effectivity of the Kono-S technique. Methods: A comprehensive search of MEDLINE (PubMed), Embase (Elsevier), Scopus (Elsevier), and Cochrane Central (Ovid) from inception to August 24th, 2023, was conducted. Studies reporting outcomes of adults with Crohn's disease undergoing ileocolic resection with subsequent Kono-S anastomosis were included. PRISMA and Cochrane guidelines were used to screen, extract and synthesize data. Primary outcomes assessed were endoscopic, surgical and clinical recurrence rates, as well as complication rates. Data were pooled using random-effects models, and heterogeneity was assessed with I² statistics. ROBINS-I and ROB2 tools were used for quality assessment. Results: 12 studies involving 820 patients met the eligibility criteria. A pooled mean follow-up time of 22.8 months (95% CI: 15.8, 29.9; I2 = 99.8%) was completed in 98.3% of patients. Pooled endoscopic recurrence was reported in 24.1% of patients (95% CI: 9.4, 49.3; I2 = 93.43%), pooled surgical recurrence in 3.9% of patients (95% CI: 2.2, 6.9; I2 = 25.97%), and pooled clinical recurrence in 26.8% of patients (95% CI: 14, 45.1; I2 = 84.87%). The pooled complication rate was 33.7%. The most common complications were infection (11.5%) and ileus (10.9%). Pooled anastomosis leakage rate was 2.9%. Conclusions: Despite limited and heterogenous data, patients undergoing Kono-S anastomosis had low rates of surgical recurrence and anastomotic leakage with moderate rates of endoscopic recurrence, clinical recurrence and complications rate.

Background: Although the beneficial properties of vitamin D in anti-inflammation and immunity-modulation are promising in the management of inflammatory bowel disease (IBD), data were limited for the critical IBD prognosis. The association between serum vitamin D levels and the risk of bowel resection in individuals with IBD remains largely unknown. Materials and Methods: The authors performed a longitudinal cohort study among 5474 individuals with IBD in the UK Biobank. Serum 25-hydroxyvitamin D [25(OH)D] was measured using direct competitive chemiluminescent immunoassay. Bowel resection events were ascertained via national inpatient data. Multivariable-adjusted Cox proportional hazard regression was used to examine the association between serum 25(OH)D and bowel resection risk, presented with hazard ratios (HRs) and 95% CIs. Restricted cubic spline (RCS) was used to evaluate dose-response associations. Results: During a mean follow-up of 13.1 years, the authors documented 513 incident bowel resection cases. Compared to participants with vitamin D deficiency, nondeficient participants showed a significantly reduced bowel resection risk in IBD (HR 0.72, 95% CI: 0.59-0.87, P=0.001), Crohn's disease (CD, HR 0.74, 95% CI: 0.56-0.98, P= 0.038), and ulcerative colitis (UC, HR 0.73, 95% CI: 0.57-0.95, P=0.020). When comparing extreme quintiles of 25(OH)D level, participants with IBD showed a 34% reduced risk of bowel resection (95% CI: 11-51%, P= 0.007) and participants with UC showed a 46% reduced risk (95% CI: 19-64%, P =0.003), while this association was not significant in CD (HR 0.93, 95% CI: 0.59-1.45, P=0.740). Linear dose-response associations were observed using the RCS curve (all P-nonlinearity > 0.05). Conclusion: Increased serum level of 25(OH)D is independently associated with reduced bowel resection risk in IBD. This association was significant in UC but may not be stable in CD. Vitamin D deficiency is a risk factor for bowel resection in individuals with IBD, and may be an effective metric in predicting and risk-screening surgical events. [ABSTRACT FROM AUTHOR]

Background: Anticoagulant therapy with heparin is the first-line treatment for acute mesenteric vein thrombosis and is effective in improving outcomes. Conversely, patients with failed early anticoagulant therapy occasionally develop bowel infarction requiring surgery. The efficacy of long-term anticoagulant therapy on recanalizing mesenteric vein thrombosis in patients with failed early anticoagulant therapy remains unclear. Herein, we report a patient who achieved recanalization of port-superior mesenteric vein thrombosis treated with anticoagulant therapy for 10 years after failed early anticoagulant therapy, followed by bowel resection. Case presentation: A 38-year-old male patient visited an outpatient clinic due to acute exacerbation of abdominal pain that had persisted for a month. He was diagnosed with port-superior mesenteric vein thrombosis on contrast-enhanced computed tomography (CT) scan and was transferred to our institution. Although he presented with abdominal pain, his respiration and circulation were stable upon hospital arrival. Anticoagulant therapy with heparin was started, and the patient was admitted to the intensive care unit. However, the patient’s abdominal pain worsened, and he began to develop signs of peritonitis. Repeat CT scan revealed bowel infarction. Thus, the patient underwent bowel resection 6 h after admission. The initial surgery was completed with open abdomen management. Bowel anastomosis was performed on the second-look surgery on the first postoperative day. Finally, the abdomen was closed on the third postoperative day after confirming the absence of bowel ischemia progression. The patient had prolonged impaired bowel function with paralytic ileus, but was discharged on the 60th postoperative day. He was then diagnosed with protein C and S deficiency based on the tests performed. Anticoagulant therapy with warfarin was initiated. He also received anticoagulant therapy in the outpatient setting. The patient’s port-superior mesenteric vein thrombosis had improved gradually with warfarin during the follow-up period. At 10 years after surgery, total occlusion of the port-superior mesenteric vein was recanalized with improvement of the portal collateral vessels. In addition, no gastric or esophageal varices were observed. Conclusions: Long-term anticoagulation therapy could affect the recanalization of extensive thrombus in multiple segments in patients with mesenteric venous thrombosis. [ABSTRACT FROM AUTHOR]

Purpose: The surgical approach to bowel endometriosis is still unclear. The aim of the study is to compare TICA to conventional specimen extractions and extra-abdominal insertion of the anvil in terms of both complications and functional outcomes. Methods: This is a single-center, observational, retrospective study conducted enrolling symptomatic women underwent laparoscopic excision of deep endometriosis with segmental bowel resection between September 2019 and June 2022. Women who underwent TICA were compared to classical technique (CT) in terms of intra- and postoperative complications, moreover, functional outcomes relating to the pelvic organs were assessed using validated questionnaires [Knowles-Eccersley-Scott-Symptom (KESS) questionnaire and Gastro-Intestinal Quality of Life Index (GIQLI)] for bowel function. Pain symptoms were assessed using Visual Analogue Scale (VAS) scores. Results: The sample included 64 women. TICA was performed on 31.2% (n = 20) of the women, whereas CT was used on 68.8% (n = 44). None of the patients experienced rectovaginal, vesicovaginal, ureteral or vesical fistula, or ureteral stenosis and uroperitoneum, and in no cases was it necessary to reoperate. Regarding the two surgical approaches, no significant difference was observed in terms of complications. As concerns pain symptoms at 6-month follow-up evaluations on stratified data, except for dysuria, all VAS scales reported showed significant reductions between median values, for both surgery interventions. As well, significant improvements were further observed in KESS scores and overall GIQLI. Only the GIQLI evaluation was significantly smaller in the TICA group compared to CT after the 6-month follow-up. Conclusions: We did not find any significant differences in terms of intra- or post-operative complications compared TICA and CT, but only a slight improvement in the Gastro-Intestinal Quality of Life Index in patients who underwent the CT compared to the TICA technique.

Abstract Background Intussusception presents a significant emergency that often necessitates bowel resection, leading to severe complications and management challenges. This study aims to investigate and establish a scoring system to enhance the prediction of bowel resection necessity in pediatric intussusception patients. Methods This retrospective study analyzed 660 hospitalized patients with intussusception who underwent surgical management at a pediatric hospital in Southwest China from April 2008 to December 2020. The necessity of bowel resection was assessed and categorized in this cohort. Variables associated with bowel resection were examined using univariate and multivariate logistic regression analyses. Based on these analyses, a scoring system was developed, grounded on the summation of the coefficients (β). Results Among the 660 patients meeting the inclusion criteria, 218 required bowel resection during surgery. Bowel resection occurrence was linked to an extended duration of symptoms (Odds Ratio [OR] = 2.14; 95% Confidence Interval [CI], 1.03–5.23; P = 0.0015), the presence of gross bloody stool (OR = 8.98; 95% CI, 1.76–48.75, P

Abstract Background Short bowel syndrome (SBS) in adults is defined as having less than 180 to 200 cm of remaining small bowel. Many literature sources do not provide precise epidemiological data, and challenges in estimating the prevalence of SBS include its multifactorial etiology and varying definitions. The most common pathologies leading to SBS include Crohn disease, mesenteric ischemia, radiation enteritis, post-surgical adhesions, and post-operative complications. Case presentation This article presents a clinical case of a 76-year-old Lithuanian patient who underwent parenteral nutrition for four months due to SBS. Before the following diagnosis, the patient had undergone two surgeries. During the hospitalization, life-threatening conditions such as stercoral peritonitis, septic shock, and acute respiratory failure, were observed and treated. As a result of SBS, hypoproteinemia and hypoalbuminemia developed, leading to the prescription of full parenteral nutrition. After correcting the malnutrition, a third surgery was performed, resulting in the discontinuation of parenteral nutrition and the resumption of a regular diet. Conclusions Parenteral nutrition is the sole effective method for preserving the lives of patients with a short segment of the intestine. While on parenteral nutrition, patients can be prepared for reconstructive surgery.

Bowel resection occurrence was linked to an extended duration of symptoms (Odds Ratio [OR] = 2.14; 95% Confidence Interval [CI], 1.03–5.23; P = 0.0015), the presence of gross bloody stool (OR = 8.98; 95% CI, 1.76–48.75, P < 0.001), elevated C-reactive protein levels (OR = 4.79; 95% CI, 1.12–28.31, P = 0.0072), lactate clearance rate (LCR) (OR = 17.25; 95% CI, 2.36–80.35; P < 0.001), and the intussusception location (OR = 12.65; 95% CI, 1.46–62.67, P < 0.001), as determined by multivariate logistic regression analysis. A scoring system (totaling 14.02 points) was developed from the cumulative β coefficients, with a threshold of 5.22 effectively differentiating infants requiring surgical intervention from others with necrotizing enterocolitis (NEC), exhibiting a sensitivity of 78.3% and a specificity of 71.9%. Conclusions: This study successfully identified multiple risk factors for bowel resection and effectively used a scoring system to identify patients for optimal clinical management.

Background: Superior mesenteric venous thrombosis (SMVT) is mostly treated with anticoagulation therapy; however, SMVT can lead to irreversible bowel ischemia and require bowel resection in the acute or subacute phase. Case presentation: We report four cases of SMVT that required careful observation and bowel resection. Case 1: A 71-year-old man presented with abdominal pain, diarrhea, and vomiting that showed a completely occluded SMV with thrombus and small bowel ischemia. Case 2: A 47-year-old man presented with abdominal pain, peritoneal irritation symptoms, and a completely occluded SMV with thrombus, ischemia of the small bowel, and massive ascites. Case 3: A 68-year-old man presented with abdominal pain and vomiting for several days and showed a partially occluded SMV with a thrombus, bowel ischemia, and massive ascites. Case 4: A 68-year-old man presented with acute abdominal pain and a partially occluded SMV with thrombus and bowel edema without ischemic changes. Anticoagulation therapy was administered; however, 3 days later, abdominal pain and bowel ischemia worsened. Bowel resection was performed in all cases. Conclusions: Most idiopathic SMVT cases can be treated with anticoagulation therapy or endovascular thrombectomy. However, in cases with peritoneal irritation signs, these treatments may be ineffective, and bowel resection may be required. [ABSTRACT FROM AUTHOR]

Despite limited research, existing studies using generic quality of life (QOL) tools indicate decreased physical health and compromised emotional functioning in children with IF. This study investigates QOL in children with short bowel syndrome (SBS) and its determinants. The study included 57 pediatric patients with SBS treated at Mannheim's University Hospital between 1998 and 2014. To evaluate QOL, the KINDL questionnaire was used. Three age-specific questionnaire variants were employed, and parental proxy reports were collected. Most patients underwent intestinal lengthening procedures, with varying primary diagnoses. A comparison with healthy children from the patient's perspective revealed no difference but from the parent's perspective showed lower QOL in SBS patients, especially regarding physical and mental well-being. QOL varied with age, with 7–10-year-olds reporting the lowest scores. Several factors, including independence from parenteral nutrition and the presence of a complete colon, positively influenced QOL. The independence of parenteral nutrition and the presence of a complete colon positively influenced QOL. The Bianchi technique for intestinal lengthening has also shown promise but needs further research. The observation sample in this study is too small to generalize about the whole population of SBS patients. However, this study shows that many health and treatment factors affect QOL, and a large multicenter study is necessary. Our findings underline the importance of appropriate psychological support for children with SBS and their families. [ABSTRACT FROM AUTHOR]

Fecal calprotectin (FC) is commonly used to assess Crohn's disease (CD) activity. However, standardized cut-off values accounting for bowel resection history and disease location are lacking. In this study, we analyzed data from patients with CD who underwent magnetic resonance enterography, ileocolonoscopy, and FC measurements from January 2017 to December 2018. In 267 cases from 254 patients, the FC levels in the 'operated' patients were higher when the disease was active compared with those who were in the remission group (178 vs. 54.7 μg/g; p < 0.001), and similar findings were obtained for the 'non-operated' patients (449.5 vs. 40.95 μg/g; p < 0.001). The FC levels differed significantly according to the location of inflammation, with lower levels in the small bowel compared to those in the colon. The FC cut-off levels of 70.8 μg/g and 142.0 μg/g were considered optimal for predicting active disease for operated and non-operated patients, respectively. The corresponding FC cut-off levels of 70.8 μg/g and 65.0 μg/g were observed for patients with disease only in the small bowel. In conclusion, different FC cut-off values would be applicable to patients with CD based on their bowel resection history and disease location. Tight control with a lower FC target may benefit those with a history of bowel resection or small-bowel-only disease. [ABSTRACT FROM AUTHOR]

Acute mesenteric ischemia is a surgical emergency with dismal prognosis. Its management consists of prompt diagnosis with expedite surgery. The ischemic bowel segments need to be resected, and a vascular intervention, thrombectomy mostly, is required in appropriate cases. The colon involvement as part of the ischemic process was rarely examined in detail. The purpose of this study was to describe the management, outcomes, and risk factors of patients with acute mesenteric ischemia involving the colon. Case series analysis of computerized historical patient records, who presented with acute mesenteric ischemia between 2010 and 2021 in a single tertiary care center, was performed. Sixty patients met the inclusion criteria and underwent surgery for acute mesenteric ischemia. Peritonitis was present in 16/60 which significantly increased mortality(p = 0.043). Twenty-one patients had intraoperative findings of colon ischemia with 14 who underwent colon resection as part of their surgery. These patients had a high mortality of 71.4%, and colon involvement was found to be a prognostic factor with p = 0.028. Patients with atrial fibrillation had a higher incidence of large bowel ischemia on computed tomography (p = 0.029). Advanced age of over 76 was also found as a risk factor for mortality. Colon involvement as part of acute mesenteric ischemia carries a dismal prognosis with high index of suspicion and prompt surgical treatment required. [ABSTRACT FROM AUTHOR]

Most cases of intestinal malrotation appear in neonates with bilious vomiting due to midgut volvulus, whereas in cases that develop beyond infancy, the initial symptoms vary. This study investigated the clinical features of these two populations and identified issues that should be considered in daily practice. A retrospective chart review was conducted from January 1, 2010, to December 31, 2022. Data on patients with intestinal malrotation were collected in an anonymized fashion from five pediatric surgical hub facilities in the Southern Kyushu and Okinawa areas of Japan. Of the 80 subjects, 57 (71.3%) were neonates (Group N) and 23 (28.7%) were infants and schoolchildren (Group I). The frequencies of initial symptoms, such as abdominal distention (Group N: 19.3% vs. Group I: 13.0%), bilious vomiting (59.6% vs. 43.5%), and hematochezia (8.8% vs. 21.7%), were not skewed by the age of onset (p = 0.535, 0.087, and 0.141, respectively). Midgut volvulus was significantly more frequent in Group N (71.9% [41/57] vs. 34.8% [8/23]; p = 0.005), while the degree of torsion was greater in group I (median 360° [interquartile range: 180–360°] vs. 450° [360–540°]; p = 0.029). Although the bowel resection rate was equivalent (7.0% [4/57] vs. 4.3% [1/23]; p = 1.000), half of the patients in Group N presented with 180° torsion. The neonatal intestine has been highlighted as being more susceptible to ischemia than that in older children. The incidence of midgut volvulus is higher in neonates than in older children. Even relatively mild torsion can cause ischemic bowel changes during the neonatal period. LEVEL III. [ABSTRACT FROM AUTHOR]

Background: Short bowel syndrome (SBS) in adults is defined as having less than 180 to 200 cm of remaining small bowel. Many literature sources do not provide precise epidemiological data, and challenges in estimating the prevalence of SBS include its multifactorial etiology and varying definitions. The most common pathologies leading to SBS include Crohn disease, mesenteric ischemia, radiation enteritis, post-surgical adhesions, and post-operative complications. Case presentation: This article presents a clinical case of a 76-year-old Lithuanian patient who underwent parenteral nutrition for four months due to SBS. Before the following diagnosis, the patient had undergone two surgeries. During the hospitalization, life-threatening conditions such as stercoral peritonitis, septic shock, and acute respiratory failure, were observed and treated. As a result of SBS, hypoproteinemia and hypoalbuminemia developed, leading to the prescription of full parenteral nutrition. After correcting the malnutrition, a third surgery was performed, resulting in the discontinuation of parenteral nutrition and the resumption of a regular diet. Conclusions: Parenteral nutrition is the sole effective method for preserving the lives of patients with a short segment of the intestine. While on parenteral nutrition, patients can be prepared for reconstructive surgery. [ABSTRACT FROM AUTHOR]

Objective To develop a nomogram for predicting the risks of early anastomotic recurrence (EAR) after primary bowel resection in patients with Crohn′s disease (CD). Methods The patients with CD undergoing preoperative magnetic resonance enterography (MRE) and primary bowel resection were enrolled in this retrospective study and divided into an EAR group (18 patients) and EAR-free group (12 patients). The EAR group included the patients having an endoscopic Rutgeerts score of ≥ I2 month or the need for anastomotic resection within 12 months after surgery. All the 38 indexes including preoperative demographic characteristics, laboratory examinations, multi-parameter MRE features of the resected intestine and its adjacent mesentery, histological findings, and postoperative pharmacotherapy were analyzed. Least absolute shrinkage and selection operator (LASSO) regression and multivariate binary logistic regression analysis were performed to identify independent risk factors to be incorporated into the nomogram for predicting the risks of early anastomotic recurrence and the prediction performance was evaluated. Results Mesenteric creeping fat index on MRE and comb sign were independent risks of EAR, with a concordance index of 0.882 (95%CI: 0.764~1). The calibration plot revealed a strong relationship between actual observation and predicted probability of EAR. Conclusions The preoperative MRE-based nomogram may be a potential tool for predicting EAR following surgery in patients with CD, which is beneficial to individual management in those patients. It provides reference for the formulation of early postoperative individualized drug adjuvant therapy in patients at high risk of EAR. [ABSTRACT FROM AUTHOR]

Background Acute mesenteric ischemia is rare, and few large‐scale trials have evaluated endovascular therapy (EVT) and open surgical revascularization (OS). This study aimed to assess clinical outcomes after EVT or OS for acute superior mesenteric artery occlusion and identify predictors of mortality and bowel resection. Methods and Results Data from the Japanese Registry of All Cardiac and Vascular Diseases‐Diagnosis Procedure Combination (JROAD‐DPC) database from April 2012 to March 2020 were retrospectively analyzed. Overall, 746 patients with acute superior mesenteric artery occlusion who underwent revascularization were classified into 2 groups: EVT (n=475) or OS (n=271). The primary clinical outcome was in‐hospital mortality. The secondary outcomes were bowel resection, bleeding complications (transfusion or endoscopic hemostasis), major adverse cardiovascular events, hospitalization duration, and cost. The in‐hospital death or bowel resection rate was ≈30%. In‐hospital mortality (22.5% versus 21.4%, P=0.72), bowel resection (8.2% versus 8.5%, P=0.90), and major adverse cardiovascular events (11.6% versus 9.2%, P=0.32) were comparable between the EVT and OS groups. Hospitalization duration in the EVT group was 6 days shorter than that in the OS group, and total hospitalization cost was 0.88 million yen lower. Interaction analyses revealed that EVT and OS had no significant difference in terms of in‐hospital death in patients with thromboembolic and atherothrombotic characteristics. Advanced age, decreased activities of daily living, chronic kidney disease, and old myocardial infarction were significant predictive factors for in‐hospital mortality. Diabetes was a predictor of bowel resection after revascularization. Conclusions EVT was comparable to OS in terms of clinical outcomes in patients with acute superior mesenteric artery occlusion. Some predictive factors for mortality or bowel resection were obtained. Registration URL: www.umin.ac.jp/ctr/; Unique Identifier: UMIN000045240.

Abstract Background It is difficult to definitively determine the degree of ischemia in the bowel in which an incarcerated groin hernia is embedded. Failure to diagnose and intervene promptly and accurately increases the rate of bowel resection and patient mortality. The aim of this study is to investigate the risk factors for incarcerated inguinal hernia complicating bowel necrosis with resection and to establish a predictive model as a reference for clinical work. Methods Patients with incarcerated groin hernia who were admitted to our hospital were retrospectively analyzed. They were divided into bowel resection and non-bowel resection groups based on whether bowel resection was performed in the surgical record and postoperative pathological results. Risk factors for the development of bowel resection in incarcerated groin hernia were analyzed by univariate analysis and multivariate logistic regression, respectively. The screened independent risk factors were used to establish a prediction model, and finally, the predictive ability and accuracy of the model were validated and the clinical benefit was analyzed. Results A total of 345 patients with incarcerated groin hernia were included, of whom 58 underwent bowel resection for bowel necrosis and 287 did not. Multifactorial logistic regression analysis identified bowel obstruction (OR, 7.285 [95% CI, 2.254–23.542], P = 0.001), peritonitis (OR, 16.786 [95% CI, 5.436–51.838], P = 0.000), duration of incarcerated groin hernia (OR, 1.009 [95% CI, 1. 001-1.018], P = 0.034), heart rate (OR, 1.109 [95% CI, 1.021–1.205], P = 0.014), and preoperative total protein (OR, 0.900 [95% CI, 0.836–0.969], P = 0.005) were independent risk factors for bowel resection in incarcerated groin hernia. The predictive value of the established prediction model was basically in agreement with the measured value with a consistency index of 0.938 (0.901–0.974) and had a good clinical benefit. Conclusion Clinical screening and management of independent risk factors for bowel resection in patients with incarcerated groin hernia should be strengthened. The predictive model developed in this study has high diagnostic efficacy for bowel resection associated with incarcerated inguinal hernia, with the aim of reducing the incidence of bowel resection and unplanned secondary surgery.

Purpose: We evaluated the effect of the two-stage laparoscopic transversus abdominis plane block (TS-L-TAPB) in comparison to thoracic epidural anaesthesia (TEA) and a one-stage L-TAPB (OS-L-TAPB) in patients who underwent elective laparoscopic bowel resection. Methods: We compared a TS-L-TAPB (266 mg bupivacaine), which was performed bilaterally at the beginning and end of surgery, with two retrospective cohorts. These were patients who had undergone a TEA (ropivacaine/sufentanil) or an OS-L-TAPB (200 mg ropivacaine) at the beginning of surgery. Oral and i.v. opiate requirements were documented over the first 3 postoperative days (POD). Results: Patients were divided into three groups TEA (n = 23), OS-L-TAPB (n = 75), and TS-L-TAPB (n = 49). By the evening of the third POD, patients with a TEA had a higher cumulative opiate requirement with a median of 45.625 mg [0; 202.5] than patients in the OS-L-TAPB group at 10 mg [0; 245.625] and the TS-L-TAPB group at 5.625 mg [0; 215.625] (p = 0.1438). One hour after arrival in the recovery room, significantly more patients in the TEA group (100%) did not need oral and i.v. opioids than in the TS-L-TAPB (78%) and OS-L-TAPB groups (68%) (p = 0.0067).This was without clinical relevance however as the median in all groups was 0 mg. On the third POD, patients in the TEA group had a significantly higher median oral and i.v. opioid dose at 40 mg [0; 80] than the TS-L-TAPB and OS-L-TAPB groups, both at 0 mg [0; 80] (p = 0.0009). Conclusion: The TS-L-TAP showed statistically significant and clinically meaningful benefits over TEA and OS-L-TAP in reducing postoperative opiate requirements. [ABSTRACT FROM AUTHOR]

Nephrolithiasis is a common urologic manifestation of Crohn's disease. The purpose of this study was to investigate the clinical characteristics, intestinal oxalate absorption, and risk factors for urinary stone formation in these patients. In total, 27 patients with Crohn's disease and 27 healthy subjects were included in the present study. Anthropometric, clinical, and 24 h urinary parameters were determined, and the [13C2]oxalate absorption test was performed. Among all patients, 18 had undergone ileal resection, 9 of whom had a history of urinary stones. Compared to healthy controls, the urinary excretion values of calcium, magnesium, potassium, sulfate, creatinine, and citrate were significantly lower in patients with Crohn's disease. Intestinal oxalate absorption, the fractional and 24 h urinary oxalate excretion, and the risk of calcium oxalate stone formation were significantly higher in patients with urolithiasis than in patients without urolithiasis or in healthy controls. Regardless of the group, between 83% and 96% of the [13C2]oxalate was detected in the urine within the first 12 h after ingestion. The length of ileum resection correlated significantly with the intestinal absorption and urinary excretion of oxalate. These findings suggest that enteric hyperoxaluria can be attributed to the hyperabsorption of oxalate following extensive ileal resection. Oral supplementation of calcium and magnesium, as well as alkali citrate therapy, should be considered as treatment options for urolithiasis. [ABSTRACT FROM AUTHOR]

Objective: Surgical management of bowel endometriosis is still controversial. Recently, many authors have pointed out the potential benefits of preserving the superior rectal artery, thus ensuring better perfusion of the anastomosis. The aim of this study was to evaluate the complication rate and functional outcomes of a bowel resection technique for deep endometriosis (DE) involving a nerve‐ and vascular‐sparing approach. Methods: A single‐center retrospective study was conducted by enrolling patients who underwent segmental resection of the rectus sigmoid for DE in our department between September 2019 and April 2022. Intraoperative and postoperative complications were recorded for each woman, and functional outcomes relating to the pelvic organs were assessed using validated questionnaires (Knowles‐Eccersley‐Scott‐Symptom [KESS] questionnaire and Gastro‐Intestinal Quality of Life Index [GIQLI] for bowel function, Bristol Female Lower Urinary Tract Symptoms [BFLUTS] for urinary function, and Female Sexual Function Index [FSFI] for sexual function). These were evaluated preoperatively and postoperatively after 6 months from surgery. Results: Sixty‐one patients were enrolled. No patients had Clavien‐Dindo grade 3 or 4 complications, there were no rectovaginal fistulas or ureteral lesions, and in no cases was it necessary to reoperate. Temporary bladder voiding deficits were reported in 8.2% of patients, which were treated with self‐catheterizations, always resolving within 45 days of surgery. Gastrointestinal function evaluated by KESS and GIQLI improved significantly after surgery, whereas sexual function appeared to worsen, although without reaching the level of statistically significant validity. Conclusion: Our vascular‐ and nerve‐sparing segmental bowel resection technique for DE had a low intraoperative and postoperative complication rate and produced an improvement in gastrointestinal function after surgery. Synopsis: Our vascular‐ and nerve‐sparing technique for bowel resection for endometriosis is associated with an improvement of gastrointestinal function and a low rate of postoperative complications.

Purpose: Midgut volvulus is an urgent disease often occurring in neonates. This study clarified the clinical features of midgut volvulus and evaluated predictors to avoid bowel resection. Methods: This bi-center retrospective study enrolled 48 patients who underwent surgery for intestinal malrotation between 2010 and 2022. Patients’ background characteristics and preoperative imaging findings were reviewed. Results: Midgut volvulus was recognized in 32 patients (66.7%), and 6 (12.5%) underwent bowel resection. Based on a receiver operating curve analysis of bowel resection, the cut-off value of the body weight at birth and at operation were 1984 g [area under the curve (AUC) 0.75, 95% confidence interval (CI) 0.52–0.99] and 2418 g (AUC 0.70, 95% CI 0.46–0.94), respectively. The cut-off value of intestinal torsion was 540° (AUC 0.76, 95% CI 0.57–0.95), and that of the time from the onset to the diagnosis was 12 h (AUC 0.85, 95% CI 0.72–0.98). For midgut volvulus with an intestinal torsion > 540°, the most sensitive preoperative imaging test was ultrasonography (75%) Patients with bloody stool tended to undergo bowel resection. Conclusions: Patients with a low body weight and bloody stool should be confirmed to have whirlpool sign by ultrasonography and scheduled for surgery as soon as possible. [ABSTRACT FROM AUTHOR]

Primary mesenteric neuroendocrine tumors represent a rare clinical entity, challenging to manage, while a combination of imaging is demanded in order to differentiate it from metastatic disease, and set the diagnosis. If the tumor is resectable, surgery is the fundament of the therapeutic approach. The appearance of a second primary mesenteric tumor suggests an unacquainted scenario. The current article presents a case of a 40-year-old woman, who underwent laparoscopic excision of a mesenteric tumor located close to the left pararenal space. Pathology with immunohistochemistry examination reported neuroendocrine tumor grade 2. No further treatment was necessary. Seven months later, 68-Gallium DOTATATE detected another primary neuroendocrine tumor located at the right retroperitoneal space without other lesions. The second tumor was also resected laparoscopically, and the pathology confirmed the diagnosis of another neuroendocrine tumor G2. The postoperative course was uneventful, and six months later the patient is disease-free. The adequacy of 68-Gallium DOTATATE for the preoperative diagnosis of primary mesenteric tumors, the role of the laparoscopic approach, and the extent of lymph node resection are matters addressed in this article.

Meckel's diverticula are one of the most common gastrointestinal anomalies, yet mesodiverticular bands are rare. The treatment of these bands commonly requires surgery. A healthy patient in his 20s presented to the emergency department with a 1 day history of acute onset abdominal pain. Computed tomography imaging was consistent with volvulus of the large intestine. In the operating room, the patient was noted to have a band between the ileal mesentery and tip of a Meckel's diverticulum, consistent with a mesodivertiular band, through which cecum had volvulized. The patient underwent resection. The patient recovered without major complications. Mesodiverticular bands are rare, but may present as hemoperitoneum, small bowel obstruction, or volvulus. Pre-operative diagnosis of a mesodiverticular band is often difficult and they are most commonly diagnosed intraoperatively. Treatment should include surgery and may include simple lysis of the band, bowel resection, or more extensive resection if other pathology is present. [ABSTRACT FROM AUTHOR]

ObjectivesTo evaluate the impact of bowel resection at the time of interval cytoreductive surgery on survival.MethodsWe identified patients with advanced ovarian cancer who underwent neoadjuvant chemotherapy and interval cytoreductive surgery between 2008 and 2018 from a single-institution tumor registry. Kaplan-Meier survival analysis and Cox proportional hazards models were performed comparing patients who underwent bowel resection to those who did not.ResultsOf 158 patients, 43 (27%) underwent bowel resection. Rates of optimal (95%) and sub-optimal (5%) resection did not differ with bowel resection. Patients that required bowel resection had worse three-year survival (43% vs. 63%), even after adjusting for confounding variables of age, stage, number of neoadjuvant cycles, R0 resection, and ASA score (HR 2.27, p

Introduction: To compare the effect of bowel resection vs stripping on the clinical outcomes of patients with FIGO II–IV ovarian cancer. Methods: We retrospectively analyzed patients with FIGO II–IV ovarian cancer who suffered from bowel involvement and underwent cytoreductive surgery between January 2014 and March 2022. Patients' survival was compared by Kaplan–Meier survival analysis and Cox proportional hazards models. Results: Four hundred and twelve patients were included. 48 patients underwent bowel resection (BR), and 364 patients underwent bowel tumor stripping (BTS). The BR group had longer operative duration, hospital stay, time to post-operative chemotherapy, and more intraoperative bleeding. The median PFS was 37 months (95% CI 12–62) in BTS compared to 25 months (95% CI 10–40) in BR among patients who achieved R0 resection (p = 0.590). Among those with R1 resection, the median PFS in BST was 23 months (95% CI 16–30) and that in BR was 15 months (95% CI 12–18, p = 0.136); moreover, a favorable median PFS was observed in BTS with residual bowel lesions (23 months, 95% CI 14–32), compared to BR (15 months, 95% CI 12–18, p = 0.144). Multivariate analysis indicated that FIGO stage, PCI, cytoreduction time and residual lesions were independent prognostic factors of PFS. Conclusion: For patients with FIGO stage II–IV ovarian cancer with bowel implicated, bowel resection is necessary to achieve complete removal to improve the survival. If complete resection was judged unfeasible, cautious decision of bowel resection is required. Neoadjuvant chemotherapy might reduce the ratio of bowel resection for some with mesenteric involvement.

In our country, a large part of patients still neglects inguinal hernia due to the low level of public awareness about the danger of obstruction and strangulation. Even with better pre and postoperative care, improved anesthetic management and advanced surgical techniques, the emergency repair of an obstructed hernia is associated with poor prognosis and a high rate of postoperative complications. This study is to assess various risk factors and therapeutic strategies for better outcome of the patients presented with an obstructed inguinal hernia at our setup. A total of 74 inguinal hernia patients with obstruction were evaluated. Majority of the patients were in the fifth and sixth decade. More than 50% of cases belong to low socio-economic strata, who do heavy work. Right-sided Indirect hernias were more common than others. Chronic cough, constipation, prostatic enlargement are common causes of increased intra-abdominal tension seen in more than 60% of cases. All of the cases were operated as an emergency procedure. Viable bowel was seen 75.46% of cases. Bowel resection and end-to-end anastomosis were done in all cases of nonviable bowel. Patients presented early with the only obstruction, had an excellent prognosis; But the danger group, where symptomatology is vague and associated with strangulation had a higher rate of complications and mortality.

Short bowel syndrome (SBS) is a severe, life-threatening condition and one of the leading causes of intestinal failure in children. Here we were interested in changes in muscle layers and especially in the myenteric plexus of the enteric nervous system (ENS) of the small bowel in the context of intestinal adaptation. Twelve rats underwent a massive resection of the small intestine to induce SBS. Sham laparotomy without small bowel transection was performed in 10 rats. Two weeks after surgery, the remaining jejunum and ileum were harvested and studied. Samples of human small bowel were obtained from patients who underwent resection of small bowel segments due to a medical indication. Morphological changes in the muscle layers and the expression of nestin, a marker for neuronal plasticity, were studied. Following SBS, muscle tissue increases significantly in both parts of the small bowel, i.e., jejunum and ileum. The leading pathophysiological mechanism of these changes is hypertrophy. Additionally, we observed an increased nestin expression in the myenteric plexus in the remaining bowel with SBS. Our human data also showed that in patients with SBS, the proportion of stem cells in the myenteric plexus had risen by more than twofold. Our findings suggest that the ENS is tightly connected to changes in intestinal muscle layers and is critically involved in the process of intestinal adaptation to SBS. [ABSTRACT FROM AUTHOR]

Background: Small bowel obstruction (SBO) is responsible for 350,000 U.S. hospitalizations and costs ~ $2.3 billion annually. The current standard of care for SBO is to trial 3 to 5 days of non-operative management. This study evaluated the factors associated with operative management. Methods: This retrospective cohort study included adult patients admitted with adhesive SBO. Exclusions were for operative intervention within 24 h or death. Results: At baseline (N = 360), mean age was 65.9 years, 57.8% female, 72.3% white, mean BMI 26.1, 38.7% with history of SBO and 98.1% had history of abdominal surgery. Symptom onset prior to hospitalization was 1–2 days. 55.6% had successful non-operative management at discharge (median length of stay 3 days) vs. 44.4% operative conversion. In univariate analyses, BMI, SBO history, surgical history, days symptom onset, vitals, abdominal pain, obstipation, acute kidney injury, and lack of small bowel feces sign on CT scan were significantly associated with operative management. In a multivariable logistic regression, after controlling all other variables, a lack of small bowel feces sign (adjusted odds ratio, aOR = 2.25, 95% CI 1.06–4.77, p = 0.04) and history of exploratory laparotomy (aOR = 0.44, 95% CI 0.21–0.90, p = 0.03) were significantly associated with operative management. Time from admission to surgery averaged 3.89 days: small bowel resection (55/160) was 4.9 days (median = 4), compared to patients without resection (3.4 days, median = 2; p = 0.00; OR = 1.2, 95% CI 1.07–1.35). Conclusions: A lack of small bowel feces sign can be a potential indicator for operative management and should be further explored. Since the median resolution of symptoms in the non-operative management group was ~ 2 days and a 20% higher odds for bowel resection each day surgery is delayed, the conservative trial period for adhesive SBO should not exceed 3 days.

Despite limited research, existing studies using generic quality of life (QOL) tools indicate decreased physical health and compromised emotional functioning in children with IF. This study investigates QOL in children with short bowel syndrome (SBS) and its determinants. The study included 57 pediatric patients with SBS treated at Mannheim’s University Hospital between 1998 and 2014. To evaluate QOL, the KINDL questionnaire was used. Three age-specific questionnaire variants were employed, and parental proxy reports were collected. Most patients underwent intestinal lengthening procedures, with varying primary diagnoses. A comparison with healthy children from the patient’s perspective revealed no difference but from the parent’s perspective showed lower QOL in SBS patients, especially regarding physical and mental well-being. QOL varied with age, with 7–10-year-olds reporting the lowest scores. Several factors, including independence from parenteral nutrition and the presence of a complete colon, positively influenced QOL. The independence of parenteral nutrition and the presence of a complete colon positively influenced QOL. The Bianchi technique for intestinal lengthening has also shown promise but needs further research. The observation sample in this study is too small to generalize about the whole population of SBS patients. However, this study shows that many health and treatment factors affect QOL, and a large multicenter study is necessary. Our findings underline the importance of appropriate psychological support for children with SBS and their families.

Fecal calprotectin (FC) is commonly used to assess Crohn’s disease (CD) activity. However, standardized cut-off values accounting for bowel resection history and disease location are lacking. In this study, we analyzed data from patients with CD who underwent magnetic resonance enterography, ileocolonoscopy, and FC measurements from January 2017 to December 2018. In 267 cases from 254 patients, the FC levels in the ‘operated’ patients were higher when the disease was active compared with those who were in the remission group (178 vs. 54.7 μg/g; p < 0.001), and similar findings were obtained for the ‘non-operated’ patients (449.5 vs. 40.95 μg/g; p < 0.001). The FC levels differed significantly according to the location of inflammation, with lower levels in the small bowel compared to those in the colon. The FC cut-off levels of 70.8 μg/g and 142.0 μg/g were considered optimal for predicting active disease for operated and non-operated patients, respectively. The corresponding FC cut-off levels of 70.8 μg/g and 65.0 μg/g were observed for patients with disease only in the small bowel. In conclusion, different FC cut-off values would be applicable to patients with CD based on their bowel resection history and disease location. Tight control with a lower FC target may benefit those with a history of bowel resection or small-bowel-only disease.

Gastrointestinal angiodysplasia is an uncommon condition often associated with significant gastrointestinal bleeding that is resistant to medical therapy. We report the clinical outcomes of two patients who successfully underwent simultaneous intraoperative endoscopic and surgical interventions for the treatment of angiodysplasia. Intraoperative endoscopic guidance was found to be useful in managing hemorrhage caused by angiodysplasia in both patients. Additionally, we performed an analysis of cases reported in the literature. Our review focused on the anatomic location of the resected bowel and the clinical outcomes of patients (n = 21) with angiodysplasia managed with intraoperative endoscopy reported in the literature.

We conducted an observational single-center cohort study on patients with recurrent high-grade serous ovarian carcinoma that underwent secondary surgical cytoreduction with extent of partial ileectomy and/or colectomy, followed by adjuvant chemotherapy (Paclitaxel-Carboplatin). All patients performed previously primary debulking surgery without residual disease, followed by three cycles of adjuvant chemotherapy. The aim of this study was to compare survival in patients with ostomy or end-to-end anastomosis that underwent secondary cytoreduction. Furthermore, we investigated the morbidity, the rate, timing and complications of the ostomy or end-to-end anastomosis after secondary cyto-reduction. [ABSTRACT FROM AUTHOR]

Background: Small bowel obstruction (SBO) is a common hospital admission diagnosis. Identification of patients who will require a surgical resection because of a nonviable small bowel remains a challenge. Through a prospective cohort study, the authors aimed to validate risk factors and scores for intestinal resection, and to develop a practical clinical score designed to guide surgical versus conservative management. Patients and Methods: All patients admitted for an acute SBO between 2004 and 2016 in the center were included. Patients were divided in three categories depending on the management: conservative, surgical with bowel resection, and surgical without bowel resection. The outcome variable was small bowel necrosis. Logistic regression models were used to identify the best predictors. Results: Seven hundred and thirteen patients were included in this study, 492 in the development cohort and 221 in the validation cohort. Sixty-seven percent had surgery, of which 21% had small bowel resection. Thirty-three percent were treated conservatively. Eight variables were identified with a strong association with small bowel resection: age 70 years of age and above, first episode of SBO, no bowel movement for greater than or equal to 3 days, abdominal guarding, C-reactive protein greater than or equal to 50, and three abdominal computer tomography scanner signs: small bowel transition point, lack of small bowel contrast enhancement, and the presence of greater than 500 ml of intra-abdominal fluid. Sensitivity and specificity of this score were 65 and 88%, respectively, and the area under the curve was 0.84 (95% CI: 0.80-0.89). Conclusion: The authors developed and validated a practical clinical severity score designed to tailor management of patients presenting with an SBO. [ABSTRACT FROM AUTHOR]
