Abstract

BACKGROUND: Almost all cholecystectomies these days are performed using laparoscopic equipment. Recently, this has been applied in all possible pathologies of the gallbladder by many surgeons. However, we occasionally have had bitter experiences, difficult operations and long operative times, when doing laparoscopic cholecystectomies. The aim of this study was to detect the factors causing long operative times, conversions to open surgery, and higher postoperative complication rates, when difficult laparoscopic cholecystectomies are encountered.
METHODS
From among the 250 patients who had undergone laparoscopic cholecystectomies during the recent 5 years (from November 1992 to January 1998), the clinical data of the 58 patients who had undergone laparoscopic cholecystectomies with operative times over 120 minutes (a long operative time) were compared with those of 45 patients with operative times of 60 minutes or less (short operative time).
RESULTS
Clinical data for the patients with long operative times showed a higher incidence of steady pain (29.3 versus 0%), fever (36.2 versus 4.4%), previous history of upper abdominal surgery (6.9 versus 4.4%), tenderness (48.3 versus 4.4%), rebound tenderness (20.0 versus 0%), palpable tender mass (12.1 versus 0%), thick abdominal wall (13.8 versus 4.4%), leukocytosis (36.2 versus 8.9%), elevated bilirubin level (10.3 versus 0%), wall thickening of the gallbladder (34.5 versus 6.7%), fibrous adhesion after gastric surgery (5.1 versus 0%), inflammatory adhesion (39.7 versus 2.2%), and contracted gallbladder (1.2 versus 0%), as well as a higher required level of surgical experience (5.2 versus 2.2%). The surgical complication rate was 13.8% in the long-operation group and 0% in the short-operation group. Laparoscopic cholecystectomy was completed successfully in 250 of the 258 patients and the overall conversion rate to open surgery was 3.1%; that of the long-operation group was 7.9%.
CONCLUSIONS
A laparoscopic cholecystectomy with a long operative time is inevitable in patients with acute severe inflammation of the gallbladder, previous history of gastric surgery, and a contracted gall-bladder. Also, the surgeon needs a learning period to be able to overcome the long operation. In spite of the higher rates complications and conversions to open surgery in the long-operation group, a difficult laparoscopic cholecystectomy with a long operative time is a clinically acceptable procedure in patients who need a cholecystectomy.
