A randomized controlled trial of laparoscopic versus open cholecystectomy in patients with cirrhotic portal hypertension.

AIM: To evaluate the characters, risks and benefits of laparoscopic cholecystectomy (LC) in cirrhotic portal hypertension (CPH) patients.

METHODS: Altogether 80 patients with symptomatic gallbladder disease and CPH, including 41 Child class A, 32 Child class B and 7 Child class C, were randomly divided into open cholecystectomy (OC) group (38 patients) and LC group (42 patients). The cohorts were well-matched for number, age, sex, Child classification and types of disease. Data of the two groups were collected and analyzed.

RESULTS: In LC group, LC was successfully performed in 36 cases, and 2 patients were converted to OC for difficulty in managing bleeding under laparoscope and dense adhesion of Calot's triangle. The rate of conversion was 5.3%. The surgical duration was 62.6+/-15.2 min. The operative blood loss was 75.5+/-15.5 mL. The time to resume diet was 18.3+/-6.5 h. Seven postoperative complications occurred in five patients (13.2%). All patients were dismissed after an average of 4.6+/-2.4 d. In OC group, the operation time was 60.5+/-17.5 min. The operative blood loss was 112.5+/-23.5 mL. The time to resume diet was 44.2+/-10.5 h. Fifteen postoperative complications occurred in 12 patients (30.0%). All patients were dismissed after an average of 7.5+/-3.5 d. There was no significant difference in operation time between OC and LC group. But LC offered several advantages over OC, including fewer blood loss and lower postoperative complication rate, shorter time to resume diet and shorter length of hospitalization in patients with CPH.

CONCLUSION: Though LC for patients with CPH is difficult, it is feasible, relatively safe, and superior to OC. It is important to know the technical characters of the operation, and pay more attention to the meticulous perioperative managements.
