Background: Acute appendicitis (AA) is the most common surgical emergency in children. Assessment scales improve the timely detection of cases., Objective: To evaluate the association of the Pediatric Appendicitis Scale (PAS) with hospital stay (HS) and postoperative complications of appendectomy., Material and Methods: Observational, analytical, longitudinal and retrolective study. Patients from 2 months to 15 years of age, without comorbidities, who underwent appendectomy for complicated (CAA) and uncomplicated (UCAA) acute appendicitis were included. PAS score prior to an appendectomy was obtained, and the time of HS and postoperative complications were evaluated., Results: 64 patients were evaluated, age 8 (IQR 8-12) years, PAS score 6 (IQR 4-8). The time from the onset of symptoms to the request for care in the emergency department was shorter (p < 0.0001) and the total neutrophil count was higher (p = 0.001) in the CAA group. No difference was shown in the PAS score between patients with CAA and UCAA (6 [4-7] vs. 7 [4-8], p = 0.087]. A PAS score ≥ 7 was associated with an increased risk of prolonged HE (p = 0.007), but was not associated with postoperative complications. The PAS score alongside the time elapsed from the onset of symptoms until the assistance in the Pediatric Emergency Department, were associated with an increased risk of prolonged HE (R2 = 0.2246, p = 0.003)., Conclusions: A PAS score ≥ 7 is associated with prolonged HS, likewise, the PAS score alongside the time elapsed between the onset of symptoms and assistance in emergency care is associated with prolonged HS., (Licencia CC 4.0 (BY-NC-ND) © 2023 Revista Médica del Instituto Mexicano del Seguro Social.)

Background: Appendicitis is the main cause of acute surgical abdomen in pediatrics. Delay in the diagnosis implies serious consequences., Objective: To know the utility of inflammation markers for predicting complicated acute appendicitis (CAA) in children., Material and Methods: Analytical cross-sectional retrolective study. We included patients from 3 to 17 years, with and without acute appendicitis (AA), who had complete blood count (CBC). Presurgical CBC, surgical findings and histopathologic results were recorded; group I, CAA; group II, uncomplicated acute appendicitis (UAA); and group III, without AA, with stratified analysis by age group., Results: 377 patients were included, 9 years of age (IQR 5-12.5), group I (n = 94), group II (n = 94) and group III (n = 189). Group I showed elevation in the values of Neutrophil/lymphocyte ratio (NLR), Platelet/lymphocyte ratio (PLR) and Systemic immune inflammation (SII) index and lower levels for the Lymphocyte/monocyte ratio (LMR). For AA, in preeschoolers, NLR (sensitivity [S]: 0.85; specificity [E]: 0.98), PLR (S: 0.76; E: 0.85), SII (S: 0.92; E: 0.92) was observed; school children, NLR (S: 0.90; E: 0.96), PLR (S: 0.70: E: 0.86), SII (S: 0.91; E: 0.91); adolescents, NLR (S: 0.85; E: 0.97), PLR (S: 0.26; E: 0.95), SII (S: 0.86; E: 0.86); in CAA, S and E decreased. NLR, PLR, LMR and SII were associated with AA in all ages; PLR and SII in preschoolers, LMR in school children were associated with CAA., Conclusion: NLR, PLR, LMR and SII are predictors of AA in pediatric age, and for AAC, PLR and SII in preschoolers and LMR in school children., (Licencia CC 4.0 (BY-NC-ND) © 2023 Revista Médica del Instituto Mexicano del Seguro Social.)

Background: Appendicitis remains a common surgical emergency in children. Empirical antibacterial treatment is indicated to reduce infective complications. We investigate the bacterial pathogens identified intra-operatively during appendectomies in children to guide empirical surgical antimicrobial prophylaxis options., Methods: A retrospective analysis of patients (< 18 years old) undergoing an appendectomy across a multisite London hospital (Nov 2019-March 2022) was undertaken. Patient-related outcomes including length of hospital stay (LOS), days of antibacterial therapy (DOT), intra-operative microbiology and post-operative radiology reports were interrogated., Results: 304 patients underwent an appendectomy during this period; 39.1% of patients had intraoperative samples cultured. Bacterial pathogens were found in 73/119 (61.3%) cases; the most common isolates being Escherichia coli (42.0%), Pseudomonas aeruginosa (21.0%), milleri Streptococcus spp. (14.3%) and Bacteroides fragilis (5.9%). Polymicrobial infection was common (32/73). Isolation of Pseudomonas spp. from intra-operative sampling was associated with a greater LOS (7.0 vs. 5.0 days; p = 0.011) but nil effect on the incidence of postoperative collections. Presence of milleri Streptococcus spp. was associated with longer LOS (7.0 vs. 5.0 day; p = 0.007), DOT (12.0 vs. 8.5 day; p = 0.007) but had no observed outcome on postoperative collections (29.4% vs. 18.6%; p = 0.330). 48% of E. coli positive cultures were co-amoxiclav resistant and prolonged LOS compared to the non-resistant group (7.0 vs. 5.0 days; p = 0.040) but had no difference in post-operative collections (29.2% vs. 17.9%; p = 0.260)., Conclusion: A high proportion of children with appendicitis have Pseudomonas spp. isolated, leading to a prolonged LOS. Evolving Enterobacterales resistance and the presence of Pseudomonas spp. necessitate extended antibacterial coverage for paediatric appendectomies with evidence of peritonitis., (© 2023.

Acute appendicitis is the most common indication for emergency abdominal surgery throughout the world and a common reason for consultation in emergency departments. In recent decades, diagnostic imaging has played a fundamental role in identifying acute appendicitis, helping to reduce the rate of blind laparotomies and hospital costs. Given the results of clinical trials supporting the use of antibiotic therapy over surgical treatment, radiologists need to know the diagnostic criteria for complicated acute appendicitis to be able to recommend the best treatment option. This review aims not only to define the diagnostic criteria for appendicitis in different imaging modalities (ultrasonography, computed tomography, and magnetic resonance imaging), but also to explain the diagnostic protocols, atypical presentations, and other conditions that can mimic appendicitis., (Copyright © 2022 SERAM.

A 40-year-old female with a 24-hour course of abdominal pain suggestive of acute appendicitis. An emergency laparotomy was performed, finding plastron in the cecum and ascending colon, color changes, with purulent liquid and 5 cm in diameter, fixed to Toldt's. It was decided to perform a right hemicolectomy with an ileotransverse end-to-side anastomosis with adequate postsurgical evolution. The histopathological report showed acute purulent diverticulitis of the cecum, which is very low incidence in the Mexican population, that's why this case report is carried out., (Copyright: © 2023 Permanyer.)

Introduction: The neutrophil-to-lymphocyte ratio (NLR) is an inflammatory biomarker that is easily calculated with data from the differential white blood cell count. The aim of our study was to analyse the role of the NLR in the detection of negative appendectomies and to compare its usefulness with other clinical, sonographic and laboratory factors previously described., Methods: We conducted a retrospective study in patients aged less than 16 years who underwent appendectomy in our hospital between 2017 and 2020. We divided patients into 2 groups based on appendiceal histological findings: NA group (negative appendicitis: absence of appendiceal inflammation) and PA group (positive appendicitis: presence of inflammation in any layer of the appendiceal wall). We analysed demographic, clinical, sonographic and laboratory characteristics., Results: We included a total of 1269 patients, 1244 in the PA group and 25 in the NA group, with no differences between groups in demographic characteristics. The proportion of patients that presented with nausea and vomiting was significantly smaller in the NA group compared to the PA group (P < .001), and there were no other differences in symptoms. The appendiceal diameter on ultrasound was significantly smaller in the NA group (8.1 ± 2.1 vs. 9.7 ± 2.8 mm; P < .001). The white blood cell and neutrophil counts and the NLR were significantly higher in the PA group (P < .001), as was the level of C-reactive protein (18.6 vs. 2.6; P = .005). The ROC curve analysis revealed that the NLR was the parameter with the highest AUC (0.879) for the diagnosis of negative appendicitis, with a cut-off point of 2.65 for a maximum sensitivity of 84.2% and specificity of 83.8%., Conclusion: The NLR is the preoperative parameter that best discriminates patients without acute appendicitis. Values of less than 2.65 should make clinicians contemplate diagnoses other than appendicitis., (Copyright © 2022. Published by Elsevier España, S.L.U.)

Clinical presentation of acute appendicitis, the most common cause of acute abdomen, is influenced by its location. The usual clinical signs of appendicitis may be completely changed or even absent in cases of atypical appendicular positions. Incisional hernia is the most common late complication of intra-abdominal operations. Organs most likely to be localized in the hernia sac are the omentum and small and large intestines. Occasionally other organs may also herniate, for example, the appendix. Incarcerations of these organs can lead to infarsation or even to gangrene. We present the case of a 59 years old patient who underwent surgical revision for an incarcerated hernia in the scar from his previous laparoscopic operation for bilateral inguinal hernia. We expected to find an incarcerated small intestinal loop in the hernia, but surprisingly we found an acutely inflamed appendix. Considering the inflammation, special care is needed to ensure thorough treatment of the inflammatory process at the site of the incarcerated hernia. This case report presents a rare form of acute appendicitis with atypical localization in the scar from a laparoscopic port; it is a rare combination of two different causes of acute abdomen.

Background and Objectives: Since the COVID-19 pandemic confinement was established in Spain on March 9, 2020, the number of visits to the pediatric Emergency Department (ED) has decreased dramatically, probably due to the fear of parents becoming infected in the hospital environment. The aim of this work was to analyze the medium-term consequences during the first 9 months after the onset of the COVID-19 pandemic in children with acute appendicitis (AA)., Material and Methods: A retrospective study was performed on children operated on for AA in our institution between 2017 and 2020, who were distributed in two groups according to the date of surgery: COVID-19 group (after March 9, 2020) and control group (before March 9, 2020). Demographic variables, associated symptoms, time from symptoms onset, hospital stay, rate of complicated AA and postoperative complications were analyzed., Results: A total of 1274 patients were included (288 COVID group; 986 control group), without demographic differences. Time from symptom onset was significantly longer in COVID-19 group (34.5 vs. 24.2h; p=0.021), although no differences in associated symptoms were observed between both groups. COVID-19 group presented a higher rate of complicated AA (20.1% vs. 14%; OR: 1.55; CI 95% [1.10-2.18]; p=0.008), a longer hospital stay (3.5 vs. 2.8 days; p=0.042) as well as a higher rate of postoperative complications (21.5% vs. 15.7%; OR: 1.47; CI 95% [(1.06-2.04)]; p=0.008)., Conclusion: In our experience there was a negative medium-term effects of the COVID-19 pandemic on children with acute appendicitis: delayed ED visits, increased rate of complicated AA, increased hospital stay and increased postoperative complications., (Copyright © 2021 FECA.

Introduction: Acute appendicitis is one of the most common acute abdominal conditions. One of its complications is postoperative formation of abscesses in the peritoneal cavity or in the retroperitoneal space. Among other things, appendicoliths left in the peritoneal cavity are responsible for this process. Their release from the lumen occurs preoperatively and during the operation. An appendicolith, with the bacteria present on its surface, provides an environment that supports the onset of an infection., Case Report: The authors present a less common case of a retroperitoneal abscess caused by an incarcerated appendicolith. Unusual is the long period between appendectomy and clinical manifestations of the abscess. The patient underwent surgical treatment with abscess evacuation and extraction of the appendicolith. The postoperative course was adequate; wound healing was supported by negative wound pressure therapy., Conclusion: During appendectomy, it is necessary to keep in mind the risk of releasing appendicoliths and their role in infectious complications. A conscientious revision of the peritoneal cavity is required, as well as a good surgical technique. If necessary, imaging methods can help to locate the appendicolith in the postoperative period.

Objective: Establish the sensibility and specificity of the neutrophil-lymphocyte rate (NLR) in pediatric patients with acute complicated appendicitis., Method: Transversal, observational, descriptive, and retrospective study of pediatric patients between 4 to 16 years old with diagnosis of acute appendicitis, who had appendectomy, from December 2017 to January 2019. We calculated the NLR in every patient. To analyze the variables, we used the test of Mann-Whitney and we value the sensibility and specificity of the NLR., Results: There were 245 patients, 81 with simple appendicitis and 144 with complicated appendicitis. Just 27 of them were laparoscopic appendectomy. The NLR had a media of 10.48 in simple appendicitis, and 13.03 in complicated ones, with a p value of 0.02. the area under the curve was 0.622. There was a rate of 8.2 in complicated appendicitis to the NLR., Conclusions: The NLR has been poorly studied in pediatric patients with acute appendicitis. In this study the NLR had a significant value in the patients with acute complicated appendicitis, with medium sensibility and a relatively low specificity., (Copyright: © 2022 Permanyer.)

Background: This study aimed to evaluate the neutrophil-lymphocyte (NLR) and platelet-lymphocyte (PLR) ratios as markers of perforated appendicitis., Methods: We conducted a cross-sectional analytical study. We performed a secondary analysis of a population of pediatric patients who underwent appendectomy between 2017 and 2019 at the Regional Hospital of Ayacucho, Peru. Logistic regression models were used to analyze markers (NLR and PLR) and perforated appendicitis. Later, ROC (receiver operating characteristic) curves were constructed, and sensitivity, specificity, and likelihood ratios were estimated., Results: We identified 31% of perforated appendicitis in 203 patients. A significant association was observed between perforated appendicitis and NLR values > 10.4 (odds ratio [OR]: 2.53; 95% confidence interval [95% CI]: 1.27-5.05) and PLR > 284 (OR: 2.11; 95% CI: 1.09-4.08) in the adjusted analysis. For these models, the areas under the curve were 0.74 (95% CI: 0.67 - 0.81) for both variables. With a cut-off point of 30% probability of perforated appendicitis, we observed sensitivity of 77.78% for both NLR and PLR (likelihood ratio +2.37 and +2.14, respectively), and specificity of 67.14% and 63.57% for NLR and PLR (likelihood ratio -0.33), respectively., Conclusions: Our study showed a significant association between NLR and PLR and acute perforated appendicitis. Future studies should validate the model and corroborate the performance of these markers., (Copyright: © 2021 Permanyer.)

Aim: The aim of the study was to determine the usefulness of known biomarkers as pre-operative predictors of complicated acute appendicitis (CAA) and perforated appendicitis (PA)., Materials and Methods: This was an observational, analytic, cross-sectional, and prospective study at Hospital Teodoro Maldonado Carbo (August 2016-December 2017). Evaluated biomarkers: white blood cells count, neutrophil percentage (N%), neutrophil-to-lymphocyte ratio, glucose, total bilirubin, C-reactive protein, and procalcitonin (PCT). The statistical analysis was performed by means of the area under the receiver operating characteristics (AUROC) curve estimation. Biomarkers' cutoff point was identified using Youden's index. Sensitivity, specificity, positive, and negative predictive value (NPV) (positive predictive value [PPV] and NPV) were estimated., Results: One hundred and twenty-eight cases were included (median age 30 years, 44% female), 70 cases (54%) corresponded to CAA (PA 38/70). N% and PCT obtained an AUROC of 78% and 80% for CAA (PA 76% and 81%), respectively. A N% > 78.1% predicted CAA with a sensitivity, specificity, PPV, and NPV of 82%, 62%, 72%, and 72% (> 74.9%, PA: 94%, 53%, 46%, and 96%), respectively. PCT > 0.14 ng/dL predicted CAA with sensitivity, specificity, PPV, and NPV of 69%, 79%, 80%, and 68% (PA: 84%, 69%, 53%, and 91%)., Conclusion: The N% and PCT represent useful pre-operative biomarkers for discarding PA when an acute appendicitis is suspected., (Copyright: © 2020 Permanyer.)

Background: After appendectomy due to complicated acute appendicitis (CAA), there are some alternatives as antibiotic scheme: ciprofloxacin/metronidazole; as well as monoscheme based on carbapenems: ertapenem, meropenem, and imipenem., Aim: This study aims to prove the efficacy of carbapenems versus ciprofloxacin/metronidazole in CAA post-operative management in terms of preventing complications during post-operative period and decreasing hospital stay., Materials and Methods: This was an observational, analytical, longitudinal, and prospective cohort study (March 2014-November 2016). Patients were classified into two groups, according to the prescribed antibiotic scheme: some carbapenems or ciprofloxacin/metronidazole., Results: Ninety-eight patients were enrolled. There was an requirement for antibiotic therapy rotation only in the ciprofloxacin/metronidazole (7/49, 14.3%; p = 0.004). Carbapenems reached a mean hospital stay of 4.45 days, in contrast with ciprofloxacin/metronidazole, 8.29 days (p = 0.020). In post-surgical follow-up, there were more cases of curative resolution in the group in the carbapenems group (35/49 vs. 15/49 p < 0.001) as well as a greater number of cases with some late infection in the ciprofloxacin/metronidazole group (1/49 vs. 10/49, p = 0.010)., Conclusion: In the post-operative management of CAA, carbapenems represent an important indication to be considered as first-line antibiotic therapy., (Copyright: © 2020 Permanyer.)

Background: Spiegel hernia is a rare type of ventral hernia that occurs when there is a defect in the semilunar line (Spiegel line) through which there is protrusion of preperitoneal fat or a peritoneal sac with or without an intra-abdominal viscus., Clinical Case: A 52-year-old female patient admitted for abdominal pain and tumor in the lower right quadrant of 15 cm. In the operating room, wall plasty was performed and when hernia sac was opened, necrotic appendicitis was identified., Conclusion: The incidence of hernia is Spiegel is very low and is lower when associated with acute appendicitis. Given its low frequency, clinical suspicion is important. The treatment is surgical., (Copyright: © 2020 Permanyer.)

Introduction and Aims: Abdominal ultrasonography is very useful for diagnosing acute appendicitis and has 59-96% sensitivity and 83-98% specificity. The aim of the present study was to determine the diagnostic yield of abdominal ultrasound imaging for acute appendicitis and identify the patient subgroups with the best results., Materials and Methods: Patients at a general hospital that underwent appendectomy due to the clinical suspicion of appendicitis, who also had a diagnostic radiologic study, within the time frame of January 2007 to December 2010, were analyzed. Ultrasound studies were considered positive when there were radiologic signs suggestive of acute appendicitis. The sensitivity, specificity, and predictive values of the diagnostic study were determined through the logistic regression method., Results: A total of 646 patients were operated on due to clinical suspicion of acute appendicitis. A diagnostic abdominal ultrasound study was carried out on 383 (59.3%) of those patients, resulting in 79% sensitivity (74-83, 95% CI), 58% specificity (39-75, 95% CI), 95% positive predictive value (92-97, 95% CI), and 20% negative predictive value (13-30, 95% CI)., Conclusions: Abdominal ultrasound imaging in patients with a high suspicion of appendicitis had a mediocre diagnostic yield, but better results could be achieved in different specific subgroups., (Copyright © 2019 Asociación Mexicana de Gastroenterología.

Aim: Determine the effect of an intervention to reduce the length of stay (LOS) in appendectomies., Methods: A four-quarter quality improvement initiative was developed after approval by the facility Quality Management Department, including educational sessions about the best practices regarding the hospital care for patients with appendicitis and recommendations to limit the LOS for no complicated appendicitis unless associated conditions were present, monitoring of the LOS and feedback to the staff and leaders., Results: 692 appendectomies were performed, 365 (52.7%)) of them during the intervention. The mean LOS was 3.94 days with a decreasing trend during the study period. The complicated appendicitis had a mean LOS of 6.42 days (SD, 3.85) during the baseline and 5.27 days (SD 2.50) during the intervention (p=0.03), representing a 17.9% reduction. The not complicated appendicitis during baseline had LOS of 3.82 days (SD 4.17) with a subsequent reduction to 2.95 days (SD 1.53) in the intervention. The total saving bed days during the intervention were 338.04 days, which 254.04 days (75.2%) were in non complicated appendectomies. One patient required readmission during the intervention because of an organ space surgical site infection, with proper recovery after antibiotic treatment., Conclusion: Our study provides evidence about the possibility to optimize the bed use with a simple educational intervention, and should be considered a step to achieve additional reductions in the hospital stay of patients who undergo laparoscopic appendectomies., (Copyright © 2019 FECA.

Objective: This article stresses an impact of appropriate management work up in the diagnosis of acute apendicitis in puerperium. Atypical clinical symptoms may cause doubts in diagnosis and may delay necessary surgical intervention., Design: Case report., Settings: Department of Gynecology and Obstetrics, 1st Faculty of Medicine, Charles University, and Hospital Na Bulovce, Prague., Methods: We present a case report describing an atypical presentation of acute apendicitis in early puerperium. Due to atypical course of the disease and atypical imaging locality and morphology, there were doubts about the diagnosis of acute apendicitis, patient was treated conservativelly and the disease later resulted in extensive surgical intervention., Conclusion: Acute appendicitis is the most common cause of non-urogenital morbidity in puerperium. Management of work up and timing of surgical intervention have key impact on maternal mortality and morbidity.

Introduction: Pain in the right iliac fossa (RIF) continues to pose diagnostic challenges. The objective of this study is the development of a RIF pain diagnosis model based on classification trees of type CHAID (Chi-Square Automatic Interaction Detection) and on an artificial neural network (ANN)., Methods: Prospective study of 252 patients who visited the hospital due to RIF pain. Demographic, clinical, physical examination and analytical data were registered. Patients were classified into 4 groups: NsP (nonspecific RIFP group), AA (acute appendicitis), NIRIF (RIF pain with no inflammation) and IRIF (RIF pain with inflammation). A CHAID-type classification tree model and an ANN were constructed. The classic models (Alvarado [ALS], Appendicitis Inflammatory Response [AIR] and Fenyö-Linberg [FLS]) were also evaluated. Discrimination was assessed using ROC curves (AUC [95% CI]) and the correct classification rate (CCR)., Results: 53% were men. Mean age 33.3±16 years. The largest group was the NsP (45%), AA (37%), NRIF (12%) and IRIF (6%). The analytical model results were: ALS (0.82 [0.76-0.87]), AIR (0.83 [0.77-0.88]) and FLS (0.88 [0.84-0.92]). CHAID determined 10 decision groups: 3 with high probability for NsP, 3 high for AA and 4 special groups with no predominant diagnosis. CCR of ANN and CHAID were 75% and 74.2%, respectively., Conclusions: The methodology based on CHAID-type classification trees establishes a diagnostic model based on four pain groups in RIF and generates decision rules that can help us in the diagnosis of processes with RIF pain., (Copyright © 2019 AEC.

Objective: To evaluate the accuracy of ultrasonography for the diagnosis of acute appendicitis in adults, to calculate the negative appendicectomy rate in operated patients and the accuracy of pre-defined diagnostic categories and to identify statistically significant signs and symptoms of acute appendicitis in ultrasonography., Material and Methods: Descriptive prospective study in which we collected the findings of the urgent ultrasonographies ordered in a one-year period for adult patients with pain in the right iliac fossa (RIF), along with their symptoms. We classified them in 5 different diagnostic categories presented in the radiological report: normal appendix, non-visible appendix and no secondary signs, non-conclusive, probable appendicitis, certain appendicitis. By mean of the Stata14 software descriptive analysis, T-test and Chi-square were performed and the data were compared with the final pathological report., Results: Population: 139 patients (45% men, 55% women), mean age: 32,68 (15-84). Prevalence of acute appendicitis: 50,35% (70/139). Negative appendicectomy rate: 0%. Negative predictive value for the categories 1,2 and 3 taken together: 90,78%. Positive predictive value for the categories 4 and 5 taken together: 100%. Ultrasound sensibility and specificity 90% and 100%, respectively. Statistically significant signs and symptoms (p<0.05): RIF pain, fever, leukocytosis, left shift, visible appendix, non-compressibility, hyperechogenic fat, appendicolith and free fluid., Conclusion: Ultrasound is very accurate for the diagnosis of acute appendicitis in adults., (Copyright © 2018 SERAM.

Introduction and Objectives: Acute appendicitis is the first cause of surgical emergencies. It is still a difficult diagnosis to make, especially in young persons, the elderly, and in reproductive-age women, in whom a series of inflammatory conditions can have signs and symptoms similar to those of acute appendicitis. Different scoring systems have been created to increase diagnostic accuracy, and they are inexpensive, noninvasive, and easy to use and reproduce. The modified Alvarado score is probably the most widely used and accepted in emergency services worldwide. On the other hand, the RIPASA score was formulated in 2010 and has greater sensitivity and specificity. There are very few studies conducted in Mexico that compare the different scoring systems for appendicitis. The aim of our article was to compare the modified Alvarado score and the RIPASA score in the diagnosis of patients with abdominal pain and suspected acute appendicitis., Material and Methods: An observational, analytic, and prolective study was conducted within the time frame of July 2002 and February 2014 at the Hospital Universitario de Puebla. The questionnaires used for the evaluation process were applied to the patients suspected of having appendicitis., Results: The RIPASA score with 8.5 as the optimal cutoff value: ROC curve (area .595), sensitivity (93.3%), specificity (8.3%), PPV (91.8%), NPV (10.1%). Modified Alvarado score with 6 as the optimal cutoff value: ROC curve (area .719), sensitivity (75%), specificity (41.6%), PPV (93.7%), NPV (12.5%)., Conclusions: The RIPASA score showed no advantages over the modified Alvarado score when applied to patients presenting with suspected acute appendicitis., (Copyright © 2018 Asociación Mexicana de Gastroenterología.

Introduction: In order to avoid delay in the diagnosis of acute appendicitis and reduce the margin of error, the use of scales has been used. The aim of this study was to compare the effectiveness of the Alvarado and RIPASA scores in the clinical diagnosis of acute appendicitis and to correlate with the histopathological results., Methods: Prospective, longitudinal, analytical, comparative and observational study. Patients with abdominal pain syndrome suggestive of acute appendicitis and submitted to surgical intervention were included; the Alvarado and RIPASA scores were simultaneously applied. The pathology report was obtained and the efficacy of both scores for the diagnosis of acute appendicitis was compared., Results: One hundred patients were included. It was shown that the RIPASA score demonstrated greater diagnostic accuracy compared to the Alvarado score, with sensitivity of 98,8% and specificity of 71,4% versus 90,7% and 64,3%, respectively. The RIPASA score showed an area under the curve of 0,88 and the Alvarado scale of 0,80., Conclusions: The RIPASA score is a more specific, convenient and accurate system than the Alvarado score for the Mexican population., (Copyright © 2017 AEC.

Objectives: To analyze the clinical presentation, management, and outcome of acute appendicitis (AA) in pregnant and nonpregnant women of childbearing age., Material and Methods: Descriptive study of 2 cohorts of women (pregnant -P- and nonpregnant -NP-). The women, who were matched according to risk factors, were included when they underwent an emergency appendectomy based on clinical suspicion of AA. We recorded age, medical history, clinical presentation, management, and outcome. Pregnant women were classified according to gestational age of the fetus (trimester)., Results: . We included 153 women (51 P, 102 NP). The mean (SD) age was 28.8 (6.5) years (P women, 29.7 [5.8] years; NP, 28.3 [6.8]; P=.242). The mean Alvarado score was 7.1 (1.6) (P, 6.7 [1.7]; NP, 7.3 [1.5]; P=.016). The rate of complicated AA was higher in P (19.6%) than NP (2.9%) women (P<.001). Pregnancy was also associated with higher rates of surgical wound infection (P, 14.0%; NP, 3.0%; P=.016) and a longer mean hospital stay (P, 5.1 [4.8] days; NP, 1.7 [1.0]; P<.001). In the third trimester of P, poorer outcomes were recorded in relation to these risks (P=.031; P=.003, and P<.001, respectively)., Conclusion: The atypical clinical presentation of AA during pregnancy makes diagnosis difficult and may lead to a higher incidence of complicated AA and surgical wound infection as well as longer hospital stays, particularly when AA presents in the third trimester.

Objetivo: Identificar la concordancia del diagnóstico macroscópico con el diagnóstico histopatológico en pacientes intervenidos -quirúrgicamente por apendicitis aguda (AA) en el Hospital General Naval de Alta Especialidad (HOSGENAES)., Método: De los pacientes con probable AA operados de apendicetomía en el servicio de cirugía general del HOSGENAES se recuperó el reporte histopatológico con apoyo del archivo electrónico HIS-2 del hospital. La concordancia se realizó por el índice kappa de Cohen., Resultados: En este estudio de 200 casos de AA, al categorizar por grupos en relación a la fase de AA fueron diagnosticados por el cirujano 5 (2.5 %) casos como apéndices aparentemente sanos o sin signos inflamatorios, 73 (36.5%) como AA congestiva-catarral, 97 (48.5 %) como flemonosa-supurada, 20 (10 %) como gangrenosa-necrosada y 5 (2.5%) como perforada. El diagnóstico histopatológico arrojó las siguientes cifras: 10 (5%) casos de apéndices sin signos inflamatorios, 61 (30.5%) casos de AA congestiva o catarral, 107 (53.5 %) flemonosa o supurada, 11 (5.5 %) como gangrenosa o necrosada, y 11 (5.5 %) como perforada., Conclusiones: Se obtuvo una baja concordancia (kappa: 0.18) en el diagnóstico de AA entre cirujanos y patólogos al clasificarla por fases., Objective: To identify the concordance of the macroscopic diagnosis with the histopathological diagnosis in patients surgically treated for Acute Appendicitis (AA) in the Naval General Hospital of High Specialty (HOSGENAES)., Methods: All the patients with probable AA operated on appendectomy, in the general surgery service of the HOSGENAES, the histopathological report was recovered with support of the HIS-2 electronic file system of the hospital, the agreement was made by Cohen’s kappa index., Results: In this study of 200 cases of AA, when categorized by groups in relation to the AA phase in the postoperative period, 5 (2.5%) cases were diagnosed by the surgeon as appendages apparently healthy or without inflammatory signs, 73 (36.5%) as congestive AA or catarrhal, 97 (48.5%) as phlegmonous or suppurative, 20 (10%) as gangrenous or necrotic and 5 (2.5%) as perforated. Histopathological diagnosis yielded the following figures: 10 (5%) cases of appendices without inflammatory signs, 61 (30.5%) cases of congestive or catarrhal AA, 107 (53.5%) phlegmonous or suppurative, 11 (5.5%) as gangrenous or necrotic and 11 (5.5%) as perforated., Conclusions: We obtained a low concordance (kappa: 0.18) in the diagnosis of AA among surgeons and pathologists when classifying it by phases., (Copyright: © 2018 Permanyer.)

Objetivo: Comparar la seguridad y la eficacia de la atención fast-track vs. atención convencional en apendicitis no complicada en un hospital pediátrico., Método: Ensayo clínico controlado, aleatorizado, con dos grupos de 30 pacientes cada uno: A) fast-track, apendicitis no complicada que cumplieron el programa; y B) atención convencional, apendicitis no complicada con atención habitual. Variables de seguridad y eficacia: proporción de complicaciones y tiempo de estancia hospitalaria., Resultados: Se incluyeron 60 pacientes, sin diferencia entre grupos: sexo masculino (53 vs. 60%), edad (8 ± 3 vs. 8 ± 2 años), tiempo de evolución (23 ± 21 vs. 24 ± 20 horas), tiempo desde ingreso a urgencias hasta inicio de cirugía (6 ± 4 vs. 8 ± 6 horas), y tipo de apendicitis edematosa (27 vs. 24%) o supurada (73 vs. 76%). La estancia hospitalaria promedio del grupo fast-track fue de 13 ± 5 vs. 72 ± 40 horas del grupo de atención convencional (p = 0.001). Hubo complicaciones en el 3 y el 6%, respectivamente (p = 1.0). La estancia hospitalaria disminuyó 2.45 días por paciente con el protocolo fast-track, lo que representa un ahorro de $ 6,731 pesos/día/paciente/hospitalización (US$ 373), sin un aumento de las complicaciones., Conclusión: El protocolo fast-track en los niños con apendicitis no complicada es seguro y efectivo en un hospital universitario. El programa fast-track aportó beneficios clínicos y económicos, ahorrando en total $ 403,860 en los 30 pacientes., Objective: To compare safety and efficacy of fast-track program vs. conventional attention in non-complicated appendicitis attending a pediatric university hospital., Method: Randomized clinical trial, comparing two groups with 30 patients each: (A) fast-track group, appendicitis agreeing the treatment protocol; and (B) conventional attention group, appendicitis following habitual surgical care. The efficacy and safety measures were length of hospital stay and proportion of complications., Results: We included 60 patients, there were no significant difference between groups with regard: male gender (53 vs. 60%), age (8 ± 3 vs. 8 ± 2 years-old), time of evolution (23 ± 21 vs. 24 ± 20 h), time since admittance to emergency and beginning of surgery (6 ± 4 vs. 8 ± 6 h), and type of appendicitis edematous (27 vs. 24%) or suppurate (73 vs. 76%). Mean length of hospital stay in fast-track group was 13 ± 5 vs. 72 ± 40 h in conventional attention (p = 0.001). The complications were 3 and 6%, respectively (p = 1.0). Fast-track program diminished length of hospital stay in 2.45 days per patient, representing a mean cost saving of 6,731 Mexican pesos per day, per patient hospitalized (US$ 373), without increased complications., Conclusion: Fast-track program in children with non-complicated appendicitis is safe and effective in pediatric university hospital; there was cost-minimization without carelessness of safety. This program support clinical and economic benefits, a total saving of 403,860 Mexican pesos for the 30 patients in the fast-track group., (Copyright: © 2018 Permanyer.)

Introduction: Non-specific acute abdominal pain is the most common process requiring differential diagnosis with appendicitis in clinical practice. The aim of this study was to assess the Paediatric Appendicitis Score in differentiating between these two entities., Material and Methods: All patients admitted due to suspicion of appendicitis were prospectively evaluated in our hospital over a two-year period. Cases of non-specific acute abdominal pain and appendicitis were enrolled in the study. Several variables were collected, including Score variables and C-reactive protein levels. Descriptive, univariate and multivariate analyses and diagnostic accuracy studies (ROC curves) were performed., Results: A total of 275 patients were studied, in which there were 143 cases of non-specific acute abdominal pain and 132 cases of appendicitis. Temperature and right iliac fossa tenderness on palpation were the variables without statistically significant differences, and with no discrimination power between groups. Pain on coughing, hopping, and/or percussion tenderness in the right lower quadrant was the variable with greater association with appendicitis. The Score correctly stratified the patients into risk groups. Substitution of temperature for C-reactive protein in the Score increased diagnostic accuracy, although with no statistically significant differences., Conclusions: The Paediatric Appendicitis Score helps in differential diagnosis between appendicitis and non-specific acute abdominal pain. It would be advisable to replace the temperature in the Score, since it has no discrimination power between these groups. C-reactive protein at a cut-off value of 25.5mg/L value could be used instead., (Copyright © 2016 Asociación Española de Pediatría. Publicado por Elsevier España, S.L.U. All rights reserved.)

Introduction: Acute appendicitis is the most common surgical disease in emergency surgery, however, it remains a diagnostic problem and represents a challenge despite the experience and the different clinical and paraclinical diagnostic methods., Objective: To evaluate in a comparative way the scale of Alvarado, AIR and RIPASA to determine which one is best as a diagnostic test of acute appendicitis in our population in order to arrive to an accurate diagnosis in the shortest possible time and cost., Method: Observational, prospective, transversal and comparative study of 137 patients to whom the scale of Alvarado, AIR and RIPASA was applied, who entered the emergency service of the Civil Hospital of Culiacán (México) with abdominal pain syndrome suggestive of acute appendicitis., Results: The Alvarado scale presented sensitivity 97.2% and specificity of 27.6%. AIR presented sensitivity of 81.9% and specificity of 89.5%. RIPASA showed the same results as Alvarado. All tests showed diagnostic accuracy above 80., Conclusions: Alvarado and RIPASA presented good sensitivity, however, AIR is more specific, and has better accuracy for the diagnosis of acute appendicitis, making a better screening and thus reducing unnecessary surgeries. Therefore, it is recommended to use more AIR than Alvarado and RIPASA., (Copyright: © 2018 Permanyer.)

Objectives: To develop the INFURG-SEMES scale (based on the emergency infections study of the Spanish Society of Emergency Medicine) using clinical and laboratory data to diagnose acute appendicitis (AA) in patients aged 2 to 20 years who were evaluated in hospital emergency departments and to compare its diagnostic yield to that of the Alvarado score., Material and Methods: Prospective observational cohort study enrolling consecutive patients between the ages of 2 and 20 years who came to 4 hospital emergency departments with abdominal pain suggestive of AA and of less than 72 hours' duration. We collected demographic, clinical, analytic (white blood cell count, differential counts, and C-reactive protein [CRP] levels), and radiographic data (ultrasound and/or computed tomography scans). We also recorded surgical data if pertinent. The main outcome was a diagnosis of AA within 14 days of the index visit., Results: We included 331 patients with a mean (SD) age of 11.8 (3.8) years; 175 (52.9%) were male. The final diagnosis was AA in 116 cases (35.0%). The INFURG-SEMES scale included the following predictors: male sex, right quadrant pain (right iliac fossa) on examination, pain on percussion, pain on walking, and elevated neutrophil count and CRP level. The areas under the receiver operating characteristic curves for the INFURG-SEMES scale and the Alvarado score, respectively, were 0.84 (95% CI, 0.79-0.88) and 0.77 (95% CI, 0.72-0.82). The difference was statistically significant (P=.002)., Conclusion: The INFURG-SEMES scale may prove useful for diagnosing AA in patients aged between 2 and 20 years evaluated for abdominal pain in hospital emergency departments. The INFURG-SEMES score showed greater discrimination than the Alvarado score.

Background: Acute appendicitis and acute cholecystitis are among the most common diagnoses that general surgeons operate on. However, it is rarely described in its synchronous form., Clinical Case: A 43 year-old woman attending the clinic for right upper quadrant pain of 11 days duration. The patient refers to intermittent radiating pain in the right side, with positive Murphy, tachycardia, and fever. The laboratory results showed white cells 16,200/mm(3), glucose 345 mg/dl, abnormal liver function tests. Acute cholecystitis was reported with ultrasound. A Masson-type incision was made, noting an enlarged pyogenic gallbladder with thickened walls, sub-hepatic abscess of approximately 300 ml, greenish-yellow colour, and foetid. An anterograde subtotal cholecystectomy is performed due to difficulty in identifying elements of Calot triangle due to the inflammatory process, opening it and extracting stones. The right iliac fossa is reviewed, finding a plastron and a sub-serous retrocaecal appendix perforated in its middle third with free fecalith and an abscess in the pelvic cavity. An anterograde appendectomy was performed and the patient progressed satisfactorily, later being discharged due to improvement., Discussion: In this patient, with a history of recurrent episodes of gallbladder pain and disseminated acute abdominal pain without peritoneal irritation, clinical suspicion was exacerbated cholecystitis with probable empyema of the gallbladder. Open surgery approach for this patient allowed access to both the appendix and gallbladder in order to perform a complete exploration of the abdominal cavity., Conclusion: The synchronous presentation of cholecystolithiasis and complicated appendicitis has not been reported in the literature., (Copyright © 2015 Academia Mexicana de Cirugía A.C.

Introduction. Amyand’s hernia is a condition in which the cecal appendix is contained within the inguinal hernia sac, its diagnosis and management continue to be a challenge as it is a rare pathology. Case report. A 10-month-old male infant with a history of extreme prematurity presented a right Amyand’s hernia and a normal appendix. The appendix was returned to the cavity and the hernia was repaired. Result. After one year of follow-up, the patient had no complications. Conclusions. Has been reported that the risk of incarceration in full-term children is 12% and in premature babies it is 39%, therefore, surgical repair of an inguinal hernia is always necessary. There is no standard treatment for Amyand hernia in children, therefore the CiX classification could be considered for management. A treatment proposal is presented in the pediatric population, where three types were included, considering the evolutionary stage of the cecal appendix and that almost all inguinal hernias in children are due to persistence of the vaginal process; therefore, surgical treatment only includes herniotomy. By not using prosthetic material, handling is facilitated and the risk of infection is reduced. [ABSTRACT FROM AUTHOR]

Introduction. Organ transposition due to situs inversus (SI) is a rare condition that makes the diagnosis of acute appendicitis difficult. This condition entails that the patient' symptoms and physical examination findings may be atypical, which requires the use of images for diagnostic confirmation in most cases. Clinical cases. Three cases of appendicitis in patients diagnosed with situs inversus are described. Two of them had a known medical history, while the third case was diagnosed intraoperatively. Results. In two patients it was decided to undergo laparoscopic surgery without additional diagnostic images. The patients progressed satisfactorily. Conclusion. Appendicitis should always be considered in the differential diagnoses in patients with pain in the left iliac fossa. It is essential to diagnose and treat appendicitis effectively to minimize associated complications. The importance of the anamnesis and the examiner's clinical suspicion are vital in these cases, which can be confirmed with diagnostic images. There may be cases where the patient's clinical condition does not allow diagnostic imaging studies to be performed, increasingly supports the use of the laparoscopic approach. It is recommended to consider the laparoscopic approach in the first instance, since it allows us to confirm the diagnosis of situs inversus totalis in case the history is unknown and facilitates timely management of the emergency.

Diverticular disease of the appendix is usually an incidental finding. Appendiceal diverticulitis presents with abdominal pain in the right iliac fossa, with symptoms in the acute phase indistinguishable from those of acute appendicitis. Radiological diagnosis of appendiceal diverticulitis is based on the identification of a diverticula arising from the appendix but can be difficult in the setting of inflammatory changes or complication as perforation which can obscure his presence. Its incidence is underestimated due to lack of awareness of its subtle radiological findings and clinical-radiological overlap with appendicitis. The resultant delayed diagnosis is associated with significant complications including a six- fold increase in the risk of perforation. [ABSTRACT FROM AUTHOR]

Objective: to describe the clinical and surgical characteristics of Peruvian patients who have undergone appendectomy. Material and methods: A systematic review of the databases PubMed, Scopus, Web of Science, Virtual Health Library, and Scielo was carried out following the PRISMA guidelines. A protocol registered in the Prospective International Registry of Systematic Reviews (PROSPERO) database under the number CRD4202424517668 was followed. The search ended on January 24, 2024. All published articles have variables on clinical manifestations, stages of appendicitis, operative technique, operative time, postoperative diagnosis, operative site infection, and hospital stay. Results: 217 studies were identified from the database search, and 10 observational studies that met the inclusion criteria were included. A total of 1766 patients undergoing appendectomy were included (53.45% male, mostly aged 25-40 years). Postoperative manifestations included pain, nausea, and vomiting. The most common stages of appendicitis were congestive (10%), phlegmonous (20%), and necrotic (22%). Laparoscopic technique was used in 35%, open in 53%, with a mean duration of 72 minutes. Diagnosis identified complicated appendicitis in 21% and uncomplicated appendicitis in 36%. Operative site infection was recorded in 7%, and the mean hospital stay was 3.67 days. Conclusions: The current study summarizes the clinical and surgical characteristics of patients who have undergone appendectomy. The implementation of preventive strategies with the aim of reducing possible postoperative complications is recommended. [ABSTRACT FROM AUTHOR]

Introduction. Acute appendicitis is a common condition, with a peak incidence between 10 and 20 years of age. Surgery is the preferred treatment and laparotomy appendectomy remains the standard, although the laparoscopic approach has shown fewer complications. The objective of this article was to characterize both the disease and the surgical treatment in Colombia, using data from official databases. Methods. The Integrated Information System for Social Protection (SISPRO) database of the Ministry of Health was accessed in February 2023. Data with diagnosis of apendicitis and with appendectomy between 2017 and 2021 were collected. Analysis was done by age, gender, and geographic location. Results. Between 2017 and 2021, 345,618 cases of appendicitis were diagnosed (51.8% females), with peak incidence at 15-20 years of age. A total of 248,133 appendectomies were performed, 16.7% by laparoscopy. The hospitals with most reported procedures were located in Bogotá, Yopal, Popayán, and Florencia. Mortality was 0.56% in men and 0.51% in women. Conclusion. Appendicitis is common, peaking at ages 10-19. Women are more likely undergo appendectomy due to other gynecological conditions. Access to appendectomy improves mortality. In these patients, 16% were laparoscopic, suggesting that more training and access to this technique is needed. This study contributes to the understanding of the epidemiology of appendicitis and appendectomies in Colombia. [ABSTRACT FROM AUTHOR]

Background: Acute appendicitis is widely recognized as the prevailing abdominal surgical emergency globally, exhibiting an annual incidence ranging from 96.5 to 100 cases per 100,000 adults. Conversely, situs inversus totalis is a rare anatomical anomaly characterized by the complete reversal of the chest and abdominal organs, occurring in approximately 1 out of every 10,000 to 50,000 individuals. Clinical case: 53-year-old female patient who presented to the emergency department with a complaint of diffuse abdominal pain of colic nature that had persisted for 5 days. The patient referred systemic hypertension, pre-diabetes mellitus type 2, and situs inversus as relevant medical history. A laparotomy procedure was conducted, revealing a perforated appendix located in the right hypochondrium. Additionally, the patient exhibited situs inversus totalis, with the colon positioned in its normal anatomical location. Conclusions: Due to the low incidence of situs inversus totalis, in cases similar to the one presented, the utilization of image studies and laboratory studies is imperative for accurate diagnosis. In the face of diagnostic suspicions and inconclusive paraclinical studies, the most effective approach is to pursue surgical examination and intervention, preferably utilizing laparoscopic techniques.

Giant Amyand hernias are exceptional inguinal hernias because they extend below the middle of the thigh in the standing position and contain the cecal appendix. We present a patient with an irreducible giant Amyand hernia, who underwent surgical repair, using a combination of techniques for its resolution. The treatment of giant inguinal hernias is quite a challenge, due to the existing anatomical distortion, and the loss of the right to domicile of the organs that it can cause. We consider that the combination of the Bassini and Lichtenstein techniques associated with the Ombrédanne and Camay maneuvers is an appropriate strategy to successfully repair grade I giant inguinal hernias. Appendectomy in Amyand type I hernia is a treatment alternative when a risk of acute appendicitis exists. [ABSTRACT FROM AUTHOR]

Objective. To analyze the accuracy of cell ratios in the diagnosis of pediatric acute appendicitis while introducing a new one --the derived neutrophil-to-lymphocyte ratio (dNLR). Materials and methods. An observational, retrospective study of patients aged 0-15 years old diagnosed with acute appendicitis (AA) and with non-surgical abdominal pain (AP) treated in our institution from 2021 to 2022 was carried out. The neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet- to-lymphocyte ratio (PLR), and dNLR were compared between groups. Results. 98 AA patients (30% of whom were female; age: 10 ± 3.3 years) and 97 AP patients (53% of whom were male; age: 9.3 ± 3.7 years) were included. NLR, MLR, PLR, and dNLR values were higher in AA patients than in AP patients: 9.6 IQR (interquartile range) 9.5 vs. 3.3 IQR 5.3: p < 0.0001; 0.7 IQR 0.6 vs. 0.46 IQR 0.7: p < 0.023; 199.8 IQR 163.9 vs. 134.0 IQR 129.2: p < 0.0001; and 5.29 IQR 3.9 vs. 2.39 IQR 2.7; p < 0.0001, respectively. Sensitivity, specificity, positive-negative predictive value, area under the ROC curve, and dNLR cut-off point for AA diagnosis were 70%, 78%, 77-72%, 0.811, and 3.98, respectively. Conclusions. Cell ratios are useful and cost-effective inflammatory parameters in the diagnosis of pediatric acute appendicitis. The results of this study suggest dNLR has the greatest clinical accuracy.

Objective. Acute appendicitis (AA) is the most frequent urgent surgical pathology in the pediatric population, but postoperative management is variable, with protocols minimizing variability. We present our results following the optimization of the management protocol in our institution in order to establish its efficacy in terms of number of infectious complications and optimization of resources in our environment. Materials and methods. An observational, retrospective study of patients undergoing AA surgery from January 2018 to August 2022 was carried out. Two cohorts were compared, both before (1) and after (2) the implementation of the new protocol. They were divided according to severity in order to conduct a subgroup-based analysis --phlegmonous (PH), gangrenous (G), and perforated (P) appendicitis. Results. 771 patients (1: 390; 2: 381) were included, with a homogeneous distribution and a median age of 9.3 ± 2.8 years. Blood tests requested prior to discharge experienced a significant reduction (PH: 3.9% vs. 0.5%; p= 0.026; G: 97.6% vs. 13.4%, p< 0.001). Days of hospital stay decreased in the PH (1.2 IQR: 0.7 vs. 1 IQR: 0.36; p< 0.001) and G (4 IQR: 1 vs. 3 IQR: 1 days; p< 0.001) subgroups. No differences in the number of abscesses were found between groups (41 vs. 43; p= 0.73), but they were noted within subgroup G (9 vs. 2; p= 0.029). A reduction in resource expenses was detected in PH and G appendicitis. Conclusions. In our study, the most widely benefited subgroup following protocol optimization was the gangrenous appendicitis subgroup, with a significant reduction in the number of complications and the use of hospital resources.

Background: The pilephlebitis is the septic thrombophlebitis of the portal venous system ranging from asymptomatic to severe complications. Diagnosed based on imaging tests, and their treatment is based on antibiotics and anticoagulant therapy. Clinic case: 24 years male, appendectomy 12 days before. Readmission for 3 days with fever, jaundice and choluria; hyperbilirrubinemia. Intravenous contrast CT is performed, showed thrombus in portal, splenic and mesenteric vein system. Diagnosis of pylephlebitis is established, initiating managed with antibiotics and anticoagulant, with favorable clinical outcome. The pylephlebitis has an estimated incidence of 2.7 cases per year, with an unspecified clinical picture ranging from asymptomatic to severe cases with septic shock and hepatic failure. There may be accompanying fever and abdominal pain in more than 80% of the cases and presenting in some cases with leukocytosis and hyperbilirrubinemia. Intravenous contrast CT is the gold standard. The treatment is based on 4 points: Septic focus control, antibiotics, early anticoagulant and resolution of complications. Conclusions: The pylephlebitis should be taken into consideration as a possible secondary complication of intraabdominal infections. A timely diagnosis with a imaging tests and apply treatment reduce their morbidity and mortality. [ABSTRACT FROM AUTHOR]

Objective. The objective of this study was to assess the results of a clinical guideline for the treatment and early discharge of patients with complicated acute appendicitis in terms of infectious complications and hospital stay. Materials and methods. A guideline for appendicitis treatment according to severity was created. Complicated appendicitis cases were treated with ceftriaxone-metronidazole for 48h, with discharge being approved if certain clinical and blood test criteria were met. A retrospective analytical study comparing the incidence of postoperative intra-abdominal abscess (IAA) and surgical site infection (SSI) in patients under 14 years of age to whom the new guideline was applied (Group A) vs. the historical cohort (Group B, treated with gentamicin-metronidazole for 5 days) was carried out. A prospective cohort study to assess which antibiotic therapy (amoxicillin-clavulanic acid or cefuroxime-metronidazole) proved more effective in patients meeting early discharge criteria was also conducted. Results. 205 patients under 14 years of age were included in Group A, whereas 109 patients were included in Group B. IAA was present in 14.3% of patients from Group A vs. 13.8% from Group B (p= 0.83), while SSI was present in 1.9% of patients from Group A vs. 8.25% from Group B (p= 0.008). Early discharge criteria were met by 62.7% of patients from Group A. Median hospital stay decreased from 6 to 3 days. At discharge, 57% of patients received amoxicillin-clavulanic acid, whereas 43% received cefuroxime-metronidazole, with no differences being found in terms of SSI (p= 0.24) or IAA (p= 0.12). Conclusions. Early discharge reduces hospital stay without increasing the risk of postoperative infectious complications. Amoxicillin-clavulanic acid is a safe option for at-home oral antibiotic therapy. [ABSTRACT FROM AUTHOR]

Introduction. Acute appendicitis is the most common cause of the acute abdomen. Based on the idea that appendicitis is a progressive disease eventually leading to perforation, removal of the appendix is the gold standard of treatment. Material and Methods. The objective of the study is to determine if there is any difference in the occurrence of postoperative complications, and if hospitalization differs depending on the appendicitis surgery method used with the patients. A retrospective analysis was made using the data from the hospital sample of patients admitted to the University Hospital in Foca in the period from January 2019 to December 2021. Results. In the period that was retrospectively analyzed, 107 patients diagnosed with acute appendicitis were operated on. There was no statistically significant difference between the treated groups in relation to the degree of appendicitis, type and duration of symptoms, diagnostic procedures and the time that had elapsed from admission to surgery. The Alverado Score in the probable appendicitis group was 41.1%. The most common symptoms were palpation sensitivity in the inguinal region (84.1%), and pain in the right lower quadrant (69.1%), intraoperative findings of uncomplicated appendicitis 58%, and 25.2% intraoperative findings inconsistent with the pathohistological ones. Conclusion. Acute appendicitis is one of the most common emergency surgical conditions, which requires surgical intervention if not treated in time, and causes life-threatening consequences. Surgical treatment with selected techniques for faster establishment of the gastrointestinal tract function, shorter stay in the hospital, faster recovery and return to daily activities.

Dropped appendicolith following an appendectomy is a rare complication which may occur as a consequence of appendicolith expulsion from the appendix due to a previous perforation or failure to identify the appendicolith. A fecalith generally becomes symptomatic over time, as a result of abscess formation, intestinal obstruction, fistula tract or inflammation of the appendiceal stump. Two cases of dropped appendicolith following an appendectomy are described hereinbelow. Case 1: A 23-year-old female patient, who underwent an appendectomy the previous day, was admitted to the emergency room due to hypogastric pain. A computed tomography (CT) scan revealed a dropped appendicolith in the right iliac fossa, and a diagnostic laparoscopy showed intra-abdominal abscesses and a dropped appendicolith in the appendicular stump. Case 2: A 77-year-old male patient, who underwent surgery for acute appendicitis caused by appendicoliths, showed abdominal distension on the sixth postoperative day. The CT scan revealed intestinal obstruction and a dropped appendicolith at bowel loops. In the surgical reintervention, erosion of the mesentery caused by the appendicolith was evidenced. Both patients progressed after the reoperations. The incidence of dropped appendicolith following an appendectomy is currently unknown since few data are available in the literature worldwide. Therefore, it is important to present these cases to expand the casuistry, learn more about dropped appendicoliths following an appendectomy, demonstrate their complications if they are not removed early and show how to prevent them. In conclusion, dropped appendicoliths following an appendectomy must be removed early to avoid complications. [ABSTRACT FROM AUTHOR]

Aim: The main objective was to determine whether in our population there was a difference in the rate of right colon cancer diagnosis for patients over 45 years of age in the 36 months following acute appendicitis compared to a control group. Patients and Methods: Retrospective cohort study with an exposed group of 300 patients with histological diagnosis of acute appendicitis and a control group of 300 patients operated on for benign pathology between January 2014 and August 2017. Electronic medical records and the Granada Cancer Registry database were cross-referenced. Results: 2/300 patients (0.7%) presented while 4/300 (1.3%) presented in the control group. Given these findings, there is no increased risk of developing colon carcinoma in patients with appendicitis (p > 0.05). Discussion: Acute appendicitis may be the first manifestation of right colon carcinoma, however, in our review we found no such association in our population. [ABSTRACT FROM AUTHOR]
