Introduction: Single incision laparoscopic cholecystectomy (SILC) is a new minimally invasive technique in treatment of benign gallbladder diseases and has been increasingly performed. We compared the clinical outcome following SILC and conventional four-port laparoscopic cholecystectomy (CLC) and evaluated the utility and safety of SILC as routine procedure.

Material and Methods: A total of 131 patients were enrolled in this study between January 2011 and July 2012 and randomized into equal arms of SILC (68 cases) and CLC (63 cases). SILC was in all cases carried out by the same surgeon. We investigated the outcomes associated with conversion rate to open surgery, operative time, blood loss, post-operative pain, postoperative nausea and vomiting (PONV), hospital stay, and adverse events. The severity of pain was compared based on the number of oral intake of NSAIDs between post operative day 1 and 3.

Results: There was no significant difference between SILS and CLC for adverse events, conversion rate, blood loss, operative time and PONV. But, SILC was associated with significantly severe pain (p=0.012).

Conclusion: SILC is useful and safe as a routine procedure, but we need to reduce the postoperative pain.
