Avoidance of bile duct injury in laparoscopic cholecystectomy with feasible intraoperative resources: A cohort study.

Laparoscopic cholecystectomy (LC) is one of the most commonly performed surgeries and is considered the standard treatment for cholelithiasis. However, it is associated with a risk of bile duct or hepatic artery injuries. This study evaluated the safety of LCs and the conversion rate (CR) by achieving a critical view of safety (CVS) and identification of Rouviere's sulcus (RS). This was a single-group cohort study that included consecutive patients undergoing LC at Smart Health Tower (Sulaimani, Iraq) from January 2021 to January 2023. The data were prospectively collected from patients' profiles or surgical notes within the hospital's database. A total of 419 patients underwent LC, of which females were the predominant gender (78.5%). The mean and median ages of the cases were 46.3±15.8 and 45 years, with a range of 2-90 years, respectively. The most common indications for surgery were biliary colic (69.5%), followed by acute cholecystitis (23.9%). The duration of the operations was significantly shorter for cases in which the CVS (45.6±17.9 min) or identification of RS (45.6±18.6 min) was achieved compared to those where the CVS (63.7±27.7 min) or RS (50.7±21.7 min) was not observed. Surgeries for patients with both CVS achievement and RS identification were also significantly less time-consuming (44.3±17.6) than counterparts (53.3±22.6). Among the cases without CVS achievement or RS identification (n=97, 23%), eight (8.2%) had adhesions, 12 (12.4%) had a distended gallbladder (GB) and 10 (10.3%) had thick GB walls. In addition, four (4.1%) experienced GB perforation, two (2.1%) had bleeding and one (1%) had stone spillage. There was no conversion. The achievement of CVS and identification of RS are practical landmarks in performing safe LC and decreasing the CR.
