Abstract
AIM: Comparative analysis of post-operative pain between Single Incision Laparoscopic Cholecystectomy and conventional Laparoscopic Cholecystectomy.
 Method: Patients suffering from symptomatic cholelithasis were randomly subjected to Single Incision Laparoscopic Cholecystectomy (SILC) and conventional four ports Laparoscopic Cholecystectomy (cLC). Data analyzed included duration of surgery, post-operative pain, For assessment of post-operative pain numeric pain scale scoring system was used and pain scoring done at four hours, twelve hours and twenty-four hours post-operatively.
 Results: The study included fifty patients operated upon from June, 2014 to May, 2014. Twenty-five patients were subjected to SILC and rest of the twenty-five underwent cLC. Pre-operative characteristics of two groups were similar and there was no significant difference between two groups based on age, sex and Body Mass Index. Post-operative pain score was higher for cLC compared to SILC at four, twelve and twenty-four hours post-operatively. The mean pain score at four hours was 4.64 ± 1.89 for SILC versus 7.72 ± 0.84 for cLC (p-value < 0.0001). While the score at twelve and twenty-four hours were 2.96 ± 1.88 and 1.80 ± 1.44 for SILC compared to 5.08 ± 1.15 and 3.80 ± 1.11 for cLC respectively.
 Conclusion: SILC is superior to cLC compared to post-operative pain as per our study.

Summary
Over the last 20 years, conventional laparoscopic cholecystectomy (cLC) as less invasive method, has replaced open cholecystectomy in the treatment of patients with symptomatic gallstone disease. A search for even more minimally invasive approaches has led to innovative techniques of single incision laparoscopic surgery (SILS) and natural orifice transluminal endoscopic surgery (NOTES). SILS is a rapidly evolving method that is complementing traditional laparoscopy in selected fields and patients[3,4] It has been suggested as a bridge between traditional laparoscopy and natural orifice transluminal endoscopic surgery (NOTES)[5]. SILC is perhaps the most common SILS procedure, used to treat patients with gall stone disease. It is being considered as no-scar surgery because the incision is placed within the umbilical scar that is not visible. SILC has shown to have reduced postoperative pain as compared to four-port cholecystectomy in a recent randomized study, the sample size was small
