We report the rare case of postoperative perianal abscess after emergency transanal hemorrhoidal dearterialization (THD) with mucopexy for Grade III hemorrhoidal disease (HD). A 68‐year‐old male presented to our hospital with rectal bleeding due to HD Grade III. He underwent THD with mucopexy with an uneventful postoperative recovery. The patient was evaluated on the 15 th postoperative day due to perianal pain without any abnormal laboratory and imaging findings. One month postoperatively he presented with perianal edema and pus discharge. During the rectal examination, a perianal abscess with a concomitant fistula was identified and was confirmed with an MRI scan. He was submitted to abscess drainage and seton placement. This report aims to raise awareness among colorectal surgeons about the risk for this specific complication during the postoperative period. Further studies, are needed so that the etiopathology of this condition is identified and the risk factors can be controlled and avoided.

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.

Abstract 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.
