J Surg Pak Jan ;15(3):122-5.

Objective To compare the conventional four port laparoscopic cholecystectomy with the single incision laparoscopic cholecystectomy (SILS). Study design Randomized controlled trial. Place & Duration of study Surgical Ward 3, Jinnah Postgraduate Medical Center Karachi, from October 2009 to March 2010. Methodology This study was carried out on sixty patients, divided into 2 equal groups of 30 patients each. Group I, was offered four port laparoscopic cholecystectomy and in group II, single incision laparoscopic surgery was performed. Mean operative time, duration of hospital stay, pain score and infection rate were compared between two groups. Results Female predominance was found. There were 26 (86.7%) and 28 (93.3%) females in group I and II respectively. Mean age of the patients was 42.67±9.05 years and 44.42±8.59 years in group I and II respectively. The operative time was 38.50±8.92 minutes and 80.17±30.16 minutes in group I and II respectively that showed significantly higher mean operative time in group II than group I (p value 0.0001). Pain was measured as continuous variable using VAS scale (0-10 cm scale). It was 2.93±0.98 in group I and 5.23±1.52 in group II. There was no case of wound infection in group I whereas in group II there were 2 (6.66%) cases. Mean hospital stay was significantly higher in group II as compared to group I. Conclusion SILS should be performed in selected patients who have more concern of cosmesis.
