Abstract
Background
: Adhesions are amongst the common reasons for open conversion of laparoscopic cholecystectomy. It is not clear whether this problem is more common with single or multiple gallstones.
Patients and Methods
: The clinical records of 110 patients with chronic cholelithiasis harboring multiple stones in the gallbladder (multiple stone group; MSG) and 45 patients with single stones in the gallbladder (SSG) undergoing laparoscopic cholecystectomy were analyzed for differences in the clinical presentation and outcome with special reference to the incidence of pericholecystic adhesions, size of the stones, and their implications for conversion and complications.
Results
: Patients in the SSG had a significantly higher incidence of dense pericholecystic adhesions in the region of the porta hepatis (P = 0.003). Eleven patients in the SSG (24.4%) were converted to open cholecystectomy. Dense pericholecystic adhesions around the porta hepatis alone contributed to nine of these conversions (81.8%). The size of the stones was significantly greater (P < 0.001) in those patients of the SSG who required conversion to open cholecystectomy. Thirteen patients of the MSG (11.8%) required conversion to open cholecystectomy. Dense pericholecystic adhesions alone contributed to conversion in four cases (30.7%), and the size of the gallstones was not significantly different (P = 0.981) in patients with or without conversion to open cholecystectomy. There was no difference in the clinical presentation or complications in the two groups of patients.
Conclusion
: Dense adhesions in the porta hepatis are significantly more common in patients with single stones and are the most common reason for open conversion.
