The Reduction of Anastomosis-Related Morbidity Using the Kono-S Anastomosis in Patients with Crohn's Disease: A Meta-Analysis.

(1) Background: we conducted this study to evaluate the effect of Kono-S anastomosis on postoperative morbidity after bowel resection for Crohn's disease. (2) Methods: This study adhered to the PRISMA guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. The primary endpoint was the overall complications rate. Secondary outcomes included specific complications analyses, disease recurrence and efficiency endpoints. A systematic literature screening was performed in major electronic scholar databases (Medline, Scopus, Web of Science), from inception to 17 January 2024. Both Random (RE) and Fixed Effects (FE) models were estimated; the reported analysis was based on the Cochran Q test results. (3) Results: Overall, eight studies and 913 patients were included in this meta-analysis. Pooled analyses confirmed that Kono-S was not superior in terms of overall morbidity (OR: 0.69 [0.42, 1.15], p = 0.16). Kono-S displayed a reduced risk for anastomotic leakage (OR: 0.34 [0.16, 0.71], p = 0.004) and reoperation (OR: 0.12 [0.05, 0.27], p < 0.001), and a shortened length of hospital stay (WMD: -0.54 [-0.73, -0.34], p < 0.001). On the contrary, Kono-S results in higher rates of postoperative SSIs (OR: 1.85 [1.02, 3.35], p = 0.04). (4) Conclusions: This study confirms a comparable morbidity, but a lower risk of anastomotic leak and reoperation of Kono-S over conventional anastomoses. Further high quality studies are required to validate these findings.

Is magnetic anal sphincter augmentation still an option in fecal incontinence treatment: a systematic review and meta-analysis.

PURPOSE: Magnetic anal sphincter (MAS) augmentation is a novel surgical option for the treatment of fecal incontinence. Current clinical evidence is conflicting. The purpose of this meta-analysis was to report the safety profile, potential benefits, and the functional efficacy of this device. METHODS: The study followed the PRISMA guidelines. Literature databases (Medline, Scopus, Web of Science, CENTRAL) were screened for eligible articles. The primary endpoint was the pooled effect of MAS in the Cleveland Clinic Incontinence Score (CCIS) score. Quality evaluation was based on the ROBINS-I and Risk of Bias 2 tool. RESULTS: Overall, 8 studies with 205 patients were included. MAS resulted in a significant reduction of CCIS values (p = 0.019), and improvement only in the embarrassment domain of FIQoL scores (p = 0.034). The overall morbidity rate was 61.8%. Postoperative adverse events included MAS explantation in 12%, infection in 5.1%, pain in 10% and obstructed defecation in 5.8% of patients. CONCLUSION: The application of MAS in patients with fecal incontinence results in the improvement of some clinical parameters with a notable morbidity rate. Due to several study limitations, further, high-quality RCTs are required to delineate the efficacy and safety of MAS.

Microvessel Density (MVD) in Patients with Osteosarcoma: A Systematic Review and Meta-Analysis.

A meta-analysis was designed and conducted to estimate the effect of tumoral microvessel density (MVD) on the survival of patients with osteosarcoma. There was no difference between high and low MVD regarding the overall (OS) and disease-free (DFS) survival. Low MVD tumors displayed a lower DFS at the third year of follow-up. Although primary metastases did not affect the mean MVD measurements, tumors with a good chemotherapy response had a higher MVD value. Although no significant differences between tumoral MVD, OS and DFS were found, good adjuvant therapy responders had a significant higher vascularization pattern.

Comparison of intracorporeal and extracorporeal anastomosis in laparoscopic right colectomy: an updated meta-analysis and trial sequential analysis.

This meta-analysis was conducted to provide updated evidence regarding perioperative safety and efficacy, of IC and EC anastomosis in laparoscopic right colectomies. In this study, the Cochrane Handbook for Systematic Reviews of Interventions and the PRISMA guidelines were applied. The study protocol received a PROSPERO registration (CRD42020214596). A systematic literature search of the electronic scholar databases (Medline, Web of Science and Scopus) was performed. To reduce type I error, a trial sequential analysis (TSA) algorithm was introduced. The quality of evidence was evaluated based on the GRADE methodology. In total, 46 studies were included in this meta-analysis, Pooled comparisons and TSA confirmed that IC is superior in terms of incisional hernia (0.29; 95%CI: 0.19, 0.44), open conversion (0.45; 95%CI: 0.30, 0.67), reoperation (0.62; 95%CI: 0.46, 0.84]), LOS (- 0.76; 95%CI: - 1.03, - 0.49), blood loss (- 11.50; 95%CI: - 18.42, - 4.58), and cosmesis (- 1.71; 95%CI: - 2.01, - 1.42). Postoperative pain and return of bowel function were, also, shortened when the anastomosis was fashioned intracorporeally. The grading of most evidence ranged from 'low' to 'high'. Due to the discrepancy in the results of RCTs and non-RCTs, and the proportionally smaller sample size of the former, further randomized trials are required to increase the evidence of this comparison.

Comparison of ointment-based agents after excisional procedures for hemorrhoidal disease: a network meta-analysis of randomized controlled trials.

INTRODUCTION: Efficient postoperative pain control is important after hemorrhoidal surgery. Although several locally applied medications have been used, current evidence regarding the optimal strategy is still conflicting. This network meta-analysis assessed analgesic efficacy and safety of the various topical medications in patients submitted to excisional procedures for hemorrhoids. METHODS: The present study followed the Cochrane Handbook for Systematic Reviews of Interventions and the PRISMA guidelines. The last systematic literature screening was performed at 15 June 2023. Comparisons were based on a random effects multivariate network meta-analysis under a Bayesian framework. RESULTS: Overall, 26 RCTs and 2132 patients were included. Regarding postoperative pain, EMLA cream (surface under the cumulative ranking curve (SUCRA) 80.3%) had the highest ranking at 12-h endpoint, while aloe vera cream (SUCRA 82.36%) scored first at 24 h. Metronidazole ointments had the highest scores at 7 and 14 days postoperatively. Aloe vera had the best analgesic profile (24-h SUCRA 84.8% and 48-h SUCRA 80.6%) during defecation. Lidocaine (SUCRA 87.9%) displayed the best performance regarding overall morbidity rates. CONCLUSIONS: Due to the inconclusive results and several study limitations, further RCTs are required.

Microvessel density in patients with gastrointestinal stromal tumors: A systematic review and meta-analysis.

BACKGROUND: Gastrointestinal stromal tumors (GISTs) are considered the most common mesenchymal tumors of the gastrointestinal tract. Microvessel density (MVD) constitutes a direct method of vascularity quantification and has been associated with survival rates in multiple malignancies. AIM: To appraise the effect of MVD on the survival of patients with GIST. METHODS: This study adhered to Systematic reviews and Meta-Analyses guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. Electronic scholar databases and grey literature repositories were systematically screened. The Fixed Effects or Random Effects models were used according to the Cochran Q test. RESULTS: In total, 6 eligible studies were identified. The pooled hazard ratio (HR) for disease free survival (DFS) was 8.52 (95%CI: 1.69-42.84, P = 0.009). The odds ratios of disease-free survival between high and low MVD groups at 12 and 60 mo did not reach statistical significance. Significant superiority of the low MVD group in terms of DFS was documented at 36 and 120 mo (OR: 8.46, P < 0.0001 and OR: 22.71, P = 0.0003, respectively) as well as at metastases rate (OR: 0.11, P = 0.0003). CONCLUSION: MVD significantly correlates with the HR of DFS and overall survival rates at 36 and 120 mo. Further prospective studies of higher methodological quality are required.

Comparison of Selected Older and Younger Patients Regarding Optimal Surgical Treatment of Colorectal Cancer: A Prospective Cohort Study.

BACKGROUND/AIM: Current evidence regarding the optimal management of older colorectal cancer patients, is conflicting. Functional deficits impact long-term survival prognosis, while frailty often results to optimal treatment postponement. Thus, the characteristics of this subgroup combined with treatment deviations further perplex optimal oncological management. The study aim was to compare survival and optimal surgery rates between older and younger colorectal cancer patients. PATIENTS AND METHODS: This study was designed as a prospective cohort. All adult (³18 years) colorectal cancer patients operated, during the 2016-2020 period, in the Department of Surgery, University Hospital of Larissa, were considered as eligible. The primary endpoint of the study was the difference in terms of the overall survival between older (>70 year) and younger (<70 years) colorectal cancer patients. RESULTS: Overall, 166 patients (60 younger and 106 older) were enrolled. Although the older subgroup displayed a higher rate (p=0.007) of ASA II and ASA III patients, mean CCI scores were comparable (p=0.384). The two subgroups were similar in terms of performed operations (p=0.140). No delay in surgery was noted. Most operations were performed using an open approach (open: 57.8% vs. laparoscopic: 42.2%), under an elective status (elective: 91% vs. emergency: 1.8%). There was no difference in terms of overall complications rate (p=0.859). Overall survival was similar (p=0.227) between the older and younger subgroups (25.68 vs. 28.48 months). CONCLUSION: Older operated patients did not differ from their younger counterparts with regard to their overall survival. Due to several study limitations, further trials are required to confirm these findings.

Large Cyst of Skene Gland: A Rare Perineum Mass.

Objective In this report we present a rare case of a large cyst of Skene gland in a female patient with a palpable vaginal mass persisting for at least 2 years. Case Report A 67-year-old female admitted to the department of urology due to the presence of "a vaginal mass" for the past 2 years. A cyst of Skene's duct was suspected based on clinical manifestation and findings of magnetic resonance imaging showing an extensive cyst formation in the upper vaginal area and anterior to the urethra. Based on these findings, a decision for surgical removement of the cyst was made. The cyst was incised, drained, and marsupialized. The postoperative recovery was uneventful, and the patient was discharged on the second postoperative day. Conclusion High clinical suspicion is important to reach this rare diagnosis. Partial excision and marsupialization of the cyst is a simple procedure with low morbidity, without recurrence, and excellent results.

Efficacy of intraoperative intravenous lidocaine infusion on postoperative opioid consumption after laparoscopic cholecystectomy: a randomized controlled trial.

PURPOSE: We designed this study to evaluate the impact of intraoperative intravenous lidocaine infusion on postoperative opioid consumption after laparoscopic cholecystectomy. METHODS: In total, 98 patients scheduled for elective laparoscopic cholecystectomy were included and randomized. In the experimental group, intravenous lidocaine (bolus 1.5 mg/kg and continuous infusion 2 mg/kg/h) was administered intraoperatively additionally to the standard analgesia, whereas the control group received a matching placebo. Blinding existed at the level of both the patient and the investigator. RESULTS: Our study failed to confirm any benefit in opioid consumption, during the postoperative period. Lidocaine resulted to reduced intraoperative systolic, diastolic, and mean arterial pressure. Lidocaine administration did not change postoperative pain scores or the incidence of shoulder pain, at any time endpoint. Moreover, we did not identify any difference in terms of postoperative sedation levels and nausea rates. CONCLUSION: Overall, lidocaine did not have any effect on postoperative analgesia after laparoscopic cholecystectomy.

A giant low-grade appendiceal mucinous neoplasm (LAMN) presenting as ileocecal intussusception: a case report.

We report the rare case of a giant low-grade appendiceal mucinous neoplasm (LAMN), presenting as ileocecal intussusception. An 80-year-old woman presented in the emergency department of our institution with progressively worsening diffuse abdominal pain during the last 24 h. A CT scan revealed a giant abdominal mass (98.7 × 127.3 × 107.6 mm) with air-fluid level and imaging characteristics of ileocecal intussusception. An emergency exploratory laparotomy was performed, and a well-circumscribed cystic mass deriving from the appendix was found. A right hemicolectomy was performed, and the histopathological examination confirmed the diagnosis of LAMN. This report aims to raise awareness among surgeons and radiologists, about LAMNs as a differential diagnosis of right iliac fossa masses presenting as acute abdomen.

The Role of Percutaneous Tibial Nerve Stimulation (PTNS) in Low Anterior Resection Syndrome (LARS): A Systematic Review and Meta-analysis.

PURPOSE: The aim of the present study was to evaluate the pooled efficacy of percutaneous tibial nerve stimulation (PTNS) in patients with low anterior resection syndrome (LARS). MATERIAL AND METHODS: This study was based on the Cochrane Handbook for Systematic Reviews of Interventions and the PRISMA guidelines. The primary endpoint was the pooled effect size of PTNS in LARS score (LARSS). Secondary endpoints included incontinence (Fecal Incontinence Score-FIC, Obstructive Defecation Syndrome-ODS), sexual functionality and quality of life (QoL) questionnaires, and manometric evaluations. Continuous outcomes were reported as weighted mean difference (WMD), with the corresponding 95% confidence interval (95% CI). Quality evaluation was performed via the National Institutes of Health (NIH) quality assessment tool. RESULTS: Overall, 5 studies were included. PTNS resulted to reduced LARSS values (WMD: - 5.68, 95%CI: - 7.73, - 3.63, p < 0.001). A similar effect was noted in St Mark's FIC (p < 0.001) and ODS (p = 0.02) score. An improvement in several QoL scales was found. There was no effect in sexual functionality and manometric measurements. Compared to sham, PTNS significantly improved LARSS. CONCLUSIONS: The application of PTNS in patients with LARS results in an improvement in multiple clinical parameters, including defecation functionality and quality of life. Due to several study limitations, further high quality RCTs are required to delineate the exact efficacy of PTNS.

Hybrid-type, multicomponent interval training upregulates musculoskeletal fitness of adults with overweight and obesity in a volume-dependent manner: A 1-year dose-response randomised controlled trial.

This study examined the dose-response effects of a 1-year hybrid-type, multicomponent interval training programme (DoIT) on various musculoskeletal fitness parameters in inactive overweight and obese adults in a gym setting. Ninety-seven middle-aged (44.8 ± 5.2 years) individuals with overweight/obesity (31.2 ± 5.7 kg/m2) (66% female) were randomly assigned to the following groups: (i) no-intervention control (CON, n = 29), (ii) DoIT performed once weekly (DoIT-1, n = 24), (iii) DoIT performed twice weekly (DoIT-2, n = 23) and (iv) DoIT performed thrice weekly (DoIT-3, n = 21). DoIT was a time-efficient, intermittent-based, multicomponent exercise protocol using progressive loaded fundamental movement patterns with prescribed work-to-rest intervals (1:3-2:1) in a circuit format (2-3 rounds). Muscular strength, muscular endurance, flexibility, passive range of motion (PRoM), static balance and functional movement screen (FMS®) were assessed at baseline, 6 and 12 months following intervention. At post-training, all exercise groups exhibited superior changes than CON in (i) muscular strength (+13%-38%, p < 0.001); (ii) muscular endurance (+42%-159%, p < 0.001); (iii) flexibility (+12%-42%, p < 0.001); (iv) PRoM (+6%-50%, p = 0.001-0.026); (v) static balance (+61%-163%, p < 0.001); and (vi) FMS (+18%-39%, p < 0.001). Although a single exercise session/week improved musculoskeletal fitness, changes demonstrated a step-wise improvement with two and three sessions/week suggesting a dose-dependent response. The response rate to training was 100% for all exercise groups. These findings suggest that a multicomponent exercise approach incorporating bodyweight drills and resistance-based alternative modes performed under real-world conditions may improve several musculoskeletal fitness indicators in a dose-dependent manner in inactive, middle-aged adults with overweight/obesity.Trial registration: ClinicalTrials.gov identifier: NCT03759951.

Determination of Factors Related to the Reversal and Perioperative Outcomes of Defunctioning Ileostomies in Patients Undergoing Rectal Cancer Surgery: A Regression Analysis Model.

PURPOSE: Defunctioning ileostomies are often performed during rectal cancer surgery. However, stomas are sometimes associated with complications, while 20-30% of them are never reversed. Additionally, ileostomy closure can have associated morbidity, with rates as high as 45%, with the respective literature evidence being scarce and conflicting. Thus, we evaluated the stoma reversal outcomes and the risk factors for non-closure after rectal cancer surgery. METHODS: This is a retrospective analysis of a prospectively collected database of all patients who had a defunctioning ileostomy at the time of resection for rectal cancer. All operations were performed by the same surgical team. A multivariable regression model was implemented. RESULTS: In this study, 129 patients (male: 68.2%, female: 31.8%) were included. Ileostomy formation was associated with a total of 31% complication rate. Eventually 73.6% of the stomas were reversed at a mean time to closure of 26.6 weeks, with a morbidity of 13.7%. Non-reversal of ileostomy was correlated with neoadjuvant CRT (OR: 0.093, 95% CI: 0.012-0.735), anastomotic leakage (OR: 0.107, 95% CI: 0.019-0.610), and lymph node yield (OR: 0.946, 95% CI: 0.897-0.998). Time to reversal was affected by the N status, the LNR, the need for adjuvant chemotherapy, and the histologic grade. CONCLUSION: In patients with rectal cancer resections, defunctioning stoma closure rate and time to closure were associated with several perioperative and pathological outcomes.

The role of the Rafaelo procedure in the management of hemorrhoidal disease: a systematic review and meta-analysis.

BACKGROUND: The aim of this study was to summarize the current evidence regarding the role of the Rafaelo procedure in the management of hemorrhoidal disease (HD). METHODS: This study was based on the Cochrane Handbook for Systematic Reviews of Interventions and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A literature search was performed (Medline, Scopus, CENTRAL, and Web of Science) from inception to 25/09/2022. Grey literature databases were also reviewed. The primary endpoint was the pooled complications rate of the Rafaelo procedure in patients with HD. Secondary endpoints included short- (bleeding, pain, thrombosis, necrosis, urinary retention, fever, oedema, anal fissure, and readmission) and long-term (stenosis, meteorism, constipation, anal tags, anal hyposensibility, reoperation, and recurrence) postoperative complication rates. Both prospective and retrospective studies were considered. Quality evaluation was performed via the ROBINS-I tool. Certainty of Evidence was based on the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology. RESULTS: Overall, 6 non-randomized studies and 327 patients were included. The overall complication rate was 17.6% (95% CI 8.8-26.3%). Short-term complications were bleeding (7.5%, 95% CI 2.5-12.5%), thrombosis (2.2%, 95% CI 0.4-4.8%), and pain (1.6%, 95% CI 0.2-3.3%). Reoperation and recurrence rates were 1.8% (95% CI 0.3-3.4%) and 4.8% (95% CI 1.2-8.4%), respectively. A significant improvement in the presenting symptoms was noted. Method approval and patient satisfaction rates were 89.1% (95% CI 81.7-96.6%) and 95% (95% CI 89.8-100%), correspondingly. Overall CoE was "Very Low". CONCLUSIONS: Further randomized controlled trials are required to delineate the exact role of the Rafaelo procedure in HD.

Microvessel density in differentiated thyroid carcinoma: A systematic review and meta-analysis.

BACKGROUND: Microvessel density (MVD) has been proposed as a direct quantification method of tumor neovascularization. However, the current literature regarding the role of MVD in differentiated thyroid carcinoma (DTC) remains inconclusive. AIM: To appraise the effect of tumoral MVD on the survival of patients with DTC. METHODS: This meta-analysis was based on the PRISMA guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. The electronic databases Medline, Web of Science, and Scopus were systematically screened. A fixed-effects or random-effects model was used, according to the Cochran Q test. The data were then extracted and assessed on the basis of the Reference Citation Analysis (https://www.referencecitationanalysis.com/). RESULTS: A total of nine studies were included in the present study. Superiority of low MVD tumors in terms of 10-year disease free survival (OR: 0.21, 95%CI: 0.08-0.53) was recorded. Lowly vascularized thyroid cancers had a lower recurrence rate (OR: 13.66, 95%CI: 3.03-61.48). Moreover, relapsing tumors [weighed mean difference (WMD): 11.92, 95%CI: 6.32-17.52] or malignancies with regional lymph node involvement (WMD: 8.53, 95%CI: 0.04-17.02) presented with higher tumoral MVD values. CONCLUSION: MVD significantly correlates with the survival outcomes of thyroid cancer patients. However, considering several study limitations, further prospective studies of higher methodological and quality level are required.

Validation and Scoring of the Greek Version of the Strategic and Clinical Quality Indicators in Postoperative Pain Management (SCQIPP) Questionnaire.

PURPOSE: The aim of this study was to validate the Greek version of the Strategic and Clinical Quality Indicators in Postoperative Pain Management (SCQIPP) questionnaire. DESIGN: The study was designed as a prospective questionnaire survey. METHODS: Overall, 210 elective surgical patients were included . SCQIPP consisted of 14 items that were scored on a five point scale. After the translation and linguistic adjustments, the tool was distributed to the surgical wards. Internal consistency reliability was assessed by Cronbach's alpha. The tool construct was generated by a principal axis factoring model with promax rotation. FINDINGS: Base Cronbach's alpha was 0.814. Due to low inter-item and item-total correlations and the increase of Cronbach's alpha (0.834) when item two was deleted, 13 items were included in the current tool version. Factor analysis identified three district subscales: nursing care, pain management, and support. Subscale and convergent validity were confirmed. The mean score of the validated tool was 55.2 (Range: 44-63). A low level of care was highlighted in most items. CONCLUSIONS: The Greek version of the SCQIPP questionnaire is a valid and efficient tool for the evaluation of the quality of care of postoperative pain management.

Change point analysis validation of the learning curve in laparoscopic colorectal surgery: Experience from a non-structured training setting.

BACKGROUND: The introduction of minimal invasive principles in colorectal surgery was a major breakthrough, resulting in multiple clinical benefits, at the cost, though, of a notably steep learning process. The development of structured nation-wide training programs led to the easier completion of the learning curve; however, these programs are not yet universally available, thus prohibiting the wider adoption of laparoscopic colorectal surgery. AIM: To display our experience in the learning curve status of laparoscopic colorectal surgery under a non-structured training setting. METHODS: We analyzed all laparoscopic colorectal procedures performed in the 2012-2019 period under a non-structured training setting. Cumulative sum analysis and change-point analysis (CPA) were introduced. RESULTS: Overall, 214 patients were included. In terms of operative time, CPA identified the 110th case as the first turning point. A plateau was reached after the 145th case. Subgroup analysis estimated the 58th for colon and 52nd case for rectum operations as the respective turning points. A learning curve pattern was confirmed for pathology outcomes, but not in the conversion to open surgery and morbidity endpoints. CONCLUSION: The learning curves in our setting validate the comparability of the results, despite the absence of National or Surgical Society driven training programs.

Effectiveness of exercise intervention during pregnancy on high-risk women for gestational diabetes mellitus prevention: A meta-analysis of published RCTs.

OBJECTIVE: We aimed at investigating the preventive role of exercise intervention during pregnancy, in high-risk women for gestational diabetes mellitus (GDM). MATERIALS AND METHODS: We searched PubMed, CENTRAL, and Scopus for randomized controlled trials (RCTs) that evaluated exercise interventions during pregnancy on women at high risk for GDM. Data were combined with random effects models. Between study heterogeneity (Cochran's Q statistic) and the extent of study effects variability [I2 with 95% confidence interval (CI)] were estimated. Sensitivity analyses examined the effect of population, intervention, and study characteristics. We also evaluated the potential for publication bias. RESULTS: Among the 1,508 high-risk women who were analyzed in 9 RCTs, 374 (24.8%) [160 (21.4%) in intervention, and 214 (28.1%) in control group] developed GDM. Women who received exercise intervention during pregnancy were less likely to develop GDM compared to those who followed the standard prenatal care (OR 0.70, 95%CI 0.52, 0.93; P-value 0.02) [Q 10.08, P-value 0.26; I2 21% (95%CI 0, 62%]. Studies with low attrition bias also showed a similar result (OR 0.70, 95%CI 0.51, 0.97; P-value 0.03). A protective effect was also supported when analysis was limited to studies including women with low education level (OR 0.55; 95%CI 0.40, 0.74; P-value 0.0001); studies with exercise intervention duration more than 20 weeks (OR 0.54; 95%CI 0.40, 0.74; P-value 0.0007); and studies with a motivation component in the intervention (OR 0.69, 95%CI 0.50, 0.96; P-value 0.03). We could not exclude large variability in study effects because the upper limit of I2 confidence interval was higher than 50% for all analyses. There was no conclusive evidence for small study effects (P-value 0.31). CONCLUSIONS: Our study might support a protective effect of exercise intervention during pregnancy for high-risk women to prevent GDM. The protective result should be corroborated by large, high quality RCTs.

Laparoscopic cholecystectomy for acalculous, gangrenous cholecystitis on an outpatient COVID-19 adult: a case report.

We report the rare case of an acalculous, gangrenous cholecystitis on a, previously healthy, outpatient COVID-19 adult. The 53-year-old patient presented to the emergency department due to epigastric pain and fever and was admitted to the COVID-19 department. Due to clinical and laboratory deterioration, a computed tomography scan was performed that confirmed the diagnosis of acalculous cholecystitis. The patient was submitted to laparoscopic cholecystectomy. Intraoperatively, a gangrenous gallbladder was identified. Immunohistology validated the presence of specimen wall vasculitis and vessel thrombosis.
