Complications of laparoscopic cholecystectomy: The experience of a university-affiliated teaching hospital

Background: In most published reports on laparoscopic cholecystectomy, the cases have been accrued from small community hospitals in a multicenter fashion. The purpose of this study was to compare the rate of complication following laparoscopic cholecystectomy performed at a single university-affiliated teaching hospital to those quoted in the literature. Study design: A retrospective review of the first 1300 laparoscopic cholecystectomies performed at the Videoscopic Surgery Center at Pennsylvania Hospital from May 1990 through January 1994 was undertaken. Complications were classified as those related to creation of the initial pneumoperitoneum and those related to cholecystectomy. Results: A 3% conversion rate to open cholecystectomy (n = 40) was noted due to the presence of dense adhesions, gangrenous cholecystitis, or difficult anatomic relationships. There were 18 complications (1.4%) related to creation of the initial pneumoperitoneum and 14 complications (1.1%) related to cholecystectomy. Complications related to laparoscopy included bleeding from the abdominal wall (n = 2), trocar site hernia (n = 11), hollow viscus injury (n = 1), and wound infection (n = 4). Complications related to cholecystectomy included unanticipated retained CBD stone (n = 5), symptomatic bile leak (n = 6), hollow viscus injury (n = 1), intraabdominal abscess (n = 1), and a retained portion of gallbladder (n = 1). There were no perioperative deaths related to laparoscopic cholecystectomy, and the overall morbidity was 2.4 %. Long-term follow-up revealed no cases of benign biliary strictures. Conclusions: With attention to anatomy, technique, and meticulous dissection, laparoscopic cholecystectomy can be safely performed in a university-affiliated teaching hospital setting.
