Comparison of single incision laparoscopic cholecystectomy with conventional laparoscopic cholecystectomy using conventional laparoscopic instrument: a prospective observational study

Abstract

Background: Laparoscopic surgery is one of the most significant surgical advances of twentieth century. Laparoscopic cholecystectomy is criterion standard for the treatment of benign gall bladder diseases, and it is the most common laparoscopic surgery worldwide. The aim of the study was to compare the intra-operative and post-operative complication, conversion rate and outcome of single incision laparoscopic cholecystectomy and conventional laparoscopic cholecystectomy on short term follow up.Methods: This prospective analytical observational design study was carried out in Tertiary Health care centre. As per convenience sampling 60 consecutive patients of cholelithiasis. Data obtained was analyzed and inferences were drawn regarding the outcomes of the SILC in terms of cosmesis, post-operative pain and any other complications and compare the outcomes against the conventional four port laparoscopic cholecystectomy.Results: In our study we found the mean operating time for SILC was 90.5±16.37 minutes, whereas the mean operating time for CLC was 74±17.83 (p = 0.0004). Intra-operative blood loss for SILC and CLC was comparable and statistically insignificant. Pain in the SILC group was found to be significantly low than CLC group (p ≤0.0001). The median cosmetic scale score for SILC group was 20 with range 13-21 and in conventional laparoscopic cholecystectomy group it was 16 with range 12-18 (p <0.0001).Conclusions: The major advantage of SILC is cosmetic satisfaction, while the disadvantages of SILS are longer operative time. There was no statistically significant difference in the intra-operative blood loss and conversion rate, and complications in both the techniques. Single incision laparoscopic cholecystectomy (SILC) was developed with the aim of reducing the invasiveness of traditional laparoscopy.
