Purpose: Limited traction has been an obstacle in the advancement of single incision laparoscopic cholecystectomy (SILC). Adequate retraction is necessary for safe performance of a cholecystectomy. In this study, we introduce our method for securing CVS for prevention of bile duct injury during performance of SILC and evaluated the effectiveness of the snake liver retractor.
Methods: A total of 148 patients who underwent needlescopic assisted SILC (nSILC) from February 2011 to February 2012 at Uijeongbu St. Mary’s Hospital, Uijeongbu, Korea were analyzed. Patients were categorized into tw o groups: G roup Ⅰ consisted of patients who underwent nSILC without use of a snake liver retractor from February 2011 to October 2011 (n=51) and group Ⅱ consisted of patients who underwent nSILC using a snake liver retractor from October 2011 to February 2012 (n=97). Patient characteristics and operative outcomes were compared between groups in order to evaluate the effectiveness of use of a snake liver retractor during performance of SILC.
Results: There were no differences in age, sex, BMI, and history of previous abdominal surgery. However, more difficult surgeries for acute cholecystitis were performed in group Ⅱ. Nevertheless, no differences in operative outcomes, such as operative time, rate of bile spillage, open conversion rate, intraoperative complication, and postoperative hospital stay were observed between groups. In addition, CVS identification time was rather shorter in group Ⅱ, compared with group Ⅰ.
Conclusion: Results of this study showed that nSILC using a snake liver retractor can allow for achievement of CVS safely and for expansion of indication for SILC through improvement of exposure and obtaining adequate traction.
