A prospective randomized controlled trial: single-incision laparoscopic cholecystectomy vs. traditional three-port laparoscopic cholecystectomy

Abstract

Objective To evaluate the clinical efficacy and safety of single-incision laparoscopic cholecystectomy(SILC) compared with conventional three-port laparoscopic cholecystectomy(3PLC). Methods Fifty-four patients diagnosed with biliary deases were included in this study at our institution. The patients were randomized into two groups: 3PLC group(n= 28) and SILC group(n= 26). Data including gender, age, weight, height, body mass index, operative duration, pain scores, percentage of conversion during the operation and vancouver scar scale were prospectively collected and analyzed. Patients were prospectively collected and analyzed. Patients were followed up for 12 months. Results There were no significant differences between the two groups with respect to gender, age, weight, height and body mass index. The operation time in SILC group was significantly longer than that in 3PLC group[(56.9±15.8) min vs.(35.2±8.7) min,P< 0.01]. On the first day after operation, the pain scores were higher for SILC with the application of equal narcotic drugs. There were no statistically signiicnat differences between the two groups in terms of total pain scores. Wound complications were severer in SILC, but there was no significant difference in incidence of incision hernia between the two groups. Cosmetic scores were favored for SILC(11.7±0.8 vs.10.1±1.2,P< 0.05). Conclusion This prospective randomized controlled study showed that SILC is safe and feasible in treating patients with simple biliary diseases compared with 3PLC.
