Introduction:Laparoscopic cholecystectomy involves removal of Gall Bladder via laparoscopy.Ambiguity continues even with regards to the possible and appropriate scientific indications regarding use of sub hepatic drainage.This study was conducted to study the indications for the insertion of sub hepatic drainage and its effects of sub hepatic drainage in a case of standard lap cholecystectomy, in terms of post–operative parameters. Material and methods: It was a 2 year study conducted at the Department of General Surgery, T.N. Medical college and B.Y.L. Nair hospital, Mumbai. We included patients who underwent standard laparoscopic cholecystectomy at our hospital from Jan 2017 to December 2018–retrospective prospective. Informed consent was taken before enrolment in the study followed by collection of data. For retrospective arm, operated cases of laparoscopic cholecystectomy performed in the hospital from January 2017 to the date of approval of the study, were studied. SPSS was used for statistical analysis Results:The highest incidence of lap cholecystectomy was in 5th decade (46%). There was increased incidence in women (84%).There was an increased incidence of drain insertion in diabetic patients.The incidence of post–operative pain in abdomen was greater in the group of patients with drain in situ while that of nausea and vomiting was higher in patients without drain in situ, though this was statistically insignificant.The mean hospital stay was greater in patients with drain (3.9 days), the difference was statistically insignificant.There were no significant advantages or obvious disadvantages of drain insertion in cases of laparoscopic cholecystectomy in this study. Conclusion: Although some cases of drain insertion were due to biliary spillage or adhesiolysis, most of cases were due to a protocol followed by the surgeons.There was no significant difference in the post–operative pain or nausea or hospital stay in both groups.
