Introduction: There are still controversies regarding the time of surgical management for acute appendicitis (AA). The main objective of this study was to recognize the surgical deferral time in patients with acute appendicitis and its relationship with the severity of presentation., Materials and Methods: We performed a retrospective review of prospectively collected data of all patients with acute appendicitis undergoing appendectomy from August 2018 to August 2020 in an academic, public hospital. Elapsed time from arrival to the emergency room to skin incision was determined. Patients were divided into three groups based on the elapsed time: less than 6 h, between 6 and 12 h, and more than 12 h., Results: A total of 782 patients were included. Of them, 443 (56.6%) patients had a surgical deferral time of less than 6 h, 238 (30.4%) patients between 6 and 12 h, and 101 (13%) patients of more than 12 h. Patients with more than 12 h of surgical deferral time had a more complicated clinical presentation (P = 0.013), a higher frequency of abscess formation (P = 0.022), higher requirement for the use of surgical drainage (P = 0.018), and longer length of hospital stay (P = <0.001)., Conclusion: Surgical deferral >12 h was associated with a higher incidence of complicated appendicitis, intra-abdominal abscesses, and overall hospital stay. However, in the multivariate analysis, only total evolution time, from the first symptom to surgery, was a significant independent predictor of complicated appendicitis., Competing Interests: Declaration of competing interest The Author(s) declare(s) that there is no conflict of interest., (Copyright © 2023 Asian Surgical Association and Taiwan Robotic Surgery Association.

Introduction: Lipomas are the most common soft tissue tumor. Giant lipomas are defined by measuring at least 10 cm in diameter in one dimension or by a minimum of 1000 g. They often are asymptomatic; however, they can cause compression syndromes due to nerve damage and difficulties in walking., Presentation of Case: We described the case of a 25-year-old female with no significant medical history who began her condition two years before her consultation. The patient referred to the appearance of a non-painful mass on her right thigh with progressive growth that hinders daily activities. A simple CT scan reported a 10.3 × 8.1 × 19.6 cm adipose mass with infiltration towards the semitendinosus muscle and the biceps femoris muscle. A free margin resection of the tumor was performed, and the involved muscles were preserved. The patient had a satisfactory postoperative outcome., Discussion: Lipomas are common benign soft tissue tumors that arise from fatty tissue and may challenge surgical management due to their extension and dimensions; they often require delicate surgical intervention due to their potential risk of malignant transformation. We believe surgical pathologists and radiologists must draw attention to muscle involvement and the infiltrative pattern., Conclusion: Giant lipomas should always raise awareness of malignant transformation. Radiological guidance should provide enough evidence to decide whether to do a biopsy or not; hence, saving the patient an extra invasive procedure. We recommend taking at least 1 cm of border margin while removing these tumors to avoid local recurrence., (Copyright © 2021 The Authors. Published by Elsevier Ltd.. All rights reserved.)

Introduction: Mirizzi syndrome is an infrequent complication of long-standing cholelithiasis. Extrinsic compression of the common hepatic duct is usually caused by an impacted stone in Hartmann's pouch or cystic duct resulting in the development of cholecystobiliary fistula. This syndrome is classified based on the presence and severity of cholecystobiliary fistula. Mirizzi syndrome is challenging to diagnose preoperatively and may require complex biliary surgical procedures for resolution., Results: We present three patients with Mirizzi syndrome with different clinical presentations. All were successfully treated by cholangioscopy with electrohydraulic lithotripsy. Endoscopic treatment is a safe alternative with a high success rate. Single-operator cholangioscopy combined with lithotripsy has been shown to have a 90-100% success rate in the treatment of biliary stones., Conclusion: Herein, we present our experience treating Mirizzi syndrome with single-operator cholangioscopy guided electrohydraulic lithotripsy. Difficult management of Mirizzi syndrome has led to research of new treatment options to minimize the risk of high-rate complications. Single-operator cholangioscopy in combination with laser lithotripsy is an adequate and safe alternative for the treatment of this condition., Competing Interests: None., (© 2021 The Author(s).)

Objectives: The present study describes a cohort of patients diagnosed with Mirizzi syndrome from type I to Vb, over a period of four years. It aimed to identify diagnostic and management pitfalls of Mirizzi syndrome, as well as their concomitant cholecystobiliary or cholecystoenteric fistulas., Material and Methods: We retrospectively reviewed all electronic medical records of patients who underwent surgery for Mirizzi syndrome at a single institution., Results: Twenty-two patients (0.6%) were diagnosed with Mirizzi syndrome. Most of the patients were females (n=19, 86.3%). Mean age was 43.8 years (range: 21-71 years). Ultrasound was performed in all (100%) patients. Six (27.2%) patients had a CT scan and six (27.2%) patients had endoscopic retrograde cholangiopancreatography. Overall preoperative diagnosis was achieved on 36.6% (n=8) of the patients. There were the same total and partial cholecystectomies, accounting for ten (45.5%) cases each, one hepaticojejunostomy with cholecystectomy (4.5%), and one enterolithotomy (4.5%). Laparoscopic cholecystectomy was attempted in 15 (68.1%) patients, with conversion to open surgery in 93.3% (n=14) of the patients. An open approach was made in five (22.7%) cases. Four (18.1%) patients were reported as MS type I, both types II and III each account for 22.7% (n=5) of the cases, there was only one (4.5%) patient with type IV, and seven (31.8%) patients with type V., Conclusion: There are limited studies of patients with Mirizzi syndrome, including type V classification, and when this syndrome is suspected, a preoperative diagnosis should be made to avoid bile duct injuries or lesions to adjacent organs., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors., (Copyright © 2020, Turkish Surgical Society.)

Purpose: Colonic volvulus constitutes a significant cause of large bowel obstruction in adults. Most studies of colonic volvulus come from high endemic zones and are limited by the small number of patients. In our region, there is a shortage of studies concerning this disorder, and treatment of colonic volvulus remains controversial., Methods: This is a retrospective study of 34 patients who presented with colonic volvulus at a single academic institution in a 4-year period and their respective treatment and outcomes., Results: A total of 34 patients, 17 males (50%) and 17 females (50%), with a mean age of 55 ± 23.9 years underwent treatment for colonic volvulus. Twelve patients (35.3%) underwent initial decompression, followed by a Hartman procedure in 4 patients (11.7%) and sigmoid resection with primary anastomosis in 3 patients (8.8%), with 3 fatalities (8.8%) following initial decompression. Two patients (5.8%) were lost to follow-up. Twenty-two patients (64.7%) underwent emergency surgery, of whom 16 (47%) underwent a Hartman procedure, with colorectal anastomosis in 9 patients (26.4%), with 3 fatalities (8.8%) immediately after the first procedure. Four patients (11.7%) were lost to follow up after the Hartman procedure. Of the 6 remaining patients (17.6%), of the emergency surgical group, 3 patients (8.8%) had an initial sigmoidectomy and primary anastomosis, and the remaining 3 patients (8.8%) had a cecal volvulus with a right hemicolectomy performed with primary anastomosis in 2 patients (5.8%) and with a fatality in the remaining patient, on whom a terminal ileostomy was performed for damage control. The mean hospital stay was 5.7 days, with an overall mortality rate of 23.5%., Conclusion: Acute colonic volvulus in our region is not as uncommon as in other parts of the world. This disorder must be suspected when a patient presents with abdominal pain, abdominal distension, and bean sign on plain X-rays and/or a whirl sign on computed tomography scan.

Background: A cholecystoenteric fistula (CEF) is an uncommon complication of gallstone disease. The aim of this study was to present our experience of a series of patients with CEF, presenting with or without gallstone ileus, along with their surgical outcomes., Methods: From 2015 to 2018, 3245 consecutive patients underwent cholecystectomy for gallbladder disease at our institution, of which 15 were diagnosed with a CEF. All electronic medical records were retrospectively reviewed., Results: Fifteen patients presented with CEF. Ten patients presented cholecystoduodenal fistula, four patients cholecystocolonic, and one patient cholecystogastric counterparts. Twelve patients were female. The median patient age was 61 years (range 33-86 years). Five patients presented with gallstone ileus treated by laparotomy and enterolithotomy. In ten patients, a laparoscopic approach was attempted, but conversion to open surgery was necessary for eight of them. The median operative time was 140 min (range 60-240 min), and the median operative blood loss was 50 mL (range 10-600 mL). The procedure-related morbidity and mortality rates were 13.3% and 6.7%, respectively., Conclusions: There is no consensus on the best treatment modality for a CEF, as the treatment outcome is mostly dependent on the surgeon's expertise and the patient's condition. Not all CEFs are accompanied by gallstone ileus. For such case, the main purpose is to resolve the intestinal obstruction and, unless necessary, avoidance of the gallbladder area., Competing Interests: Competing interest No benefits in any form have been received or will be received from a commercial party related directly or indirectly to the subject of this article., (Copyright © 2019 First Affiliated Hospital, Zhejiang University School of Medicine in China.

Background: Intragastric migration is a late and rare postsurgical complication in patients with gastric band placement. Gastric band erosion rate has previously been described to be 1.46%. In this report, we present the case of a 43-y-old male with gastric band erosion undergoing a laparoendoscopic retrieval of the gastric band, due to intragastric migration., Method: A hybrid procedure was performed to retrieve the gastric band. A laparoscopic approach was initially used to extract the connecting tube. Endoscopy was then performed to cut the gastric band with a specific cutter system and was subsequently extracted transorally., Results: The postoperative course was uneventful. Clear liquids were started on day 1, and the patient was discharged on day 2., Discussion: The purpose of this study was to describe a hybrid technique for the removal of an eroded gastric band, as a safe and feasible option in patients with band erosions., Conclusion: The laparoscopic approach enables safe extraction of the connecting tube, while endoscopy allows extraction of the band without creating a large incision in the stomach.
