Background: Incarceration of calculi in the cystic duct or gallbladder neck is a significant cause of acute cholecystitis (AC). We evaluated the difference in the clinical outcomes of laparoscopic cholecystectomy (LC) between patients with a cystic duct stone and those with a gallbladder neck stone.
Methods: A total of 36 patients who underwent LC within 7 days of onset of AC between April 2012 and March 2018 were enrolled in this study. The subjects were divided into 2 groups (Group D and Group N) according to their preoperative CT and/or MRI findings; group D comprised 7 patients with a cystic duct stone and group N comprised 20 patients with a gallbladder neck stone. The preoperative characteristics and intra- and postoperative factors were compared between the two groups.
Results: The number of patients with remnant gallbladder mucosa was significantly higher in group D. Intraoperative cholangiography was relatively difficult to perform in group D, and 2 patients developed cholangitis due to a remnant common bile duct stone (CBDS). The rate of difficult LC was not remarkably different between the two groups.
Conclusion: In group D, remnant gallbladder mucosa and remnant CBDS were considered as risk factors for LC.
