Prevalence of postcholecystectomy symptoms: long-term outcome after open versus laparoscopic cholecystectomy.

After cholecystectomy a certain number of patients continue to suffer from abdominal symptoms or develop such symptoms postoperatively. The aim of this study was to compare the prevalence of postcholecystectomy symptoms with open cholecystectomy during the prelaparoscopic era and those with laparoscopic cholecystectomy 4 years after introduction of the laparoscopic technique. Between July 1988 and June 1989 a total of 163 consecutive patients with elective open cholecystectomy and between September 1994 and August 1995 a total of 234 consecutive patients with elective laparoscopic cholecystectomy were prospectively evaluated using a standard questionnaire about preoperative symptoms, diagnostic modalities, and intraoperative findings. After a minimum of 12 months the patients were interviewed by telephone. Since the introduction of the minimal invasive technique the number of cholecystectomies performed at our institution increased. There was no significant difference in the prevalence of postcholecystectomy symptoms found after the open procedure compared with laparoscopic cholecystectomy: 90% of patients after open and 94% after laparoscopic cholecystectomy had no or only minor symptoms.
