Short and long term outcome after laparoscopic cholecystectomy.

Background: As an audit of patients undergoing laparoscopic cholecystectomy this study not only reports the short term results, but attempted to assess the long term effect of the operation on the symptom profiles of the patients.

Methods: Three hundred unselected consecutive patients underwent elective laparoscopic cholecystectomy from January 1991 to July 1994. Short term outcome was analysed by reviewing patient files for operation details, postoperative morbidity, complications, and gallbladder histology. Long term (median 2 years) outcome was evaluated by a detailed postal questionnaire. Symptomatic benefit ratios (BR) accruing from the laparoscopic removal of the gallbladder were calculated.

Results: Twelve operations (4.0%) were converted to open surgery and were excluded from long term outcome analyses. Median operation time was 93 (range 40-245) minutes. There were no deaths. Overall morbidity was 13 %. Median postoperative hospital stay was 2 days (range 1-18 days) and median time-off work 15 days (range 2-49 days). The overall response rate to the questionnaire was 87%. Only one of the 261 patients (0.4%) suffered from recurrent common bile duct stones so far. As shown by the benefit ratios the symptoms most effectively relieved by laparoscopic cholecystectomy were biliary pain (0.97), nausea (0.95), vomiting (0.96) and jaundice (0.94). Most patients with diarrhoea (0.70) and heartburn (0.66) felt relief. Constipation (0.39) and food intolerance (0.57) were unaffected. Most patients (90%) felt that the operation-initiating symptom had disappeared and 98 percent of the patients considered that they had obtained overall symptomatic improvement by the operation.

Conclusions: Laparoscopic cholecystectomy appears to be a safe and effective way of treating the most common symptoms related to gallstone disease.
