Purpose: Retained stones (RS) in the common bile duct (CBD) are one of the major problems after laparoscopic cholecystectomy and usually require endoscopic treatment. However, few reports have investigated risk factors for the development of RS in the CBD.
Methods: A total of 325 patients with acute cholecystitis underwent laparoscopic cholecystectomy at our hospital between January 2013 and Jury 2021.
Purpose: Gangrenous cholecystitis (GC) is a severe type of acute cholecystitis that implies higher mortality and morbidity rates than uncomplicated cholecystitis. The characteristics of GC are various for each case. However, preoperative predictors of GC with extensive necrotic change have not been investigated well.

Article Synopsis
- A retrospective study was conducted to assess the safety and feasibility of laparoscopic hernia repair in patients aged 80 and older, including 607 patients who underwent this procedure between 2014 and 2020.
- The study found that octo- and nonagenarian patients had a significantly higher rate of bilateral hernia repairs compared to younger patients, with no significant difference in postoperative complications between the two age groups.
- Laparoscopic repair was shown to have lower complication and readmission rates compared to open hernia repair, suggesting that it is a more effective and suitable option for older patients, particularly for identifying and addressing hernias on both sides simultaneously.

Article Synopsis
- * A library of surgical videos was evaluated by 51 experts to assess various factors affecting surgical difficulty, analyzing their agreement on the difficulty ratings.
- * The findings led to the development of a new surgical difficulty grading system, which aims to provide a standardized and objective way to evaluate the complexity of LC procedures.
Purpose: Nonoperative management (NOM) has been widely accepted as one of the standard treatments for patients with acute appendicitis. However, predictive factors for the failure of NOM have not been thoroughly investigated.
Methods: A total of 196 patients with acute appendicitis underwent NOM between April 2014 and December 2020.
