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 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.
