Simplified risk stratification in early cholecystectomy for acute cholecystitis based on age: A report from an institution with zero mortality.

Background/purpose: The existing risk stratification for early cholecystectomy in patients with acute cholecystitis (AC) is complex. This study aims to establish a simpler risk assessment for surgical complications after cholecystectomy based on age group.

Methods: This single-center retrospective observational study enrolled 350 patients diagnosed with AC who underwent early cholecystectomy within 72 h of diagnosis from 2013 to 2021.

Feasibility of a new approach for creating a preperitoneal space in transabdominal preperitoneal repair inguinal hernia repair: using a sandwich approach.

Purpose: In Japan, transabdominal preperitoneal (TAPP) inguinal hernia repair is performed by firmly pulling the peritoneum inwards to lift it from the underlying deep layer of subperitoneal fascia. It decreases the postoperative pain and discomfort in the inguinal area. The aim of this study was to evaluate the feasibility of the sandwich approach, which is a new technique for creating a preperitoneal space.
