Comparison of two different suture techniques in laparoscopic partial nephrectomy

Objective: To comparatively evaluate the traditional interrupted knot-tying and running suture renorrhaphy with Monocryl (R) in laparoscopic partial nephrectomy (LPN). Materials and Methods: A retrospective analysis of 62 consecutive patients undergoing LPN using traditional interrupted knot-tying suture renorrhaphy (Group 1; n= 31) or running suture technique renorrhaphy with 2-0 monofilament polyglecaprone (Monocryl (R), Ethicon) (Group 2; n= 31) from December 2011 to October 2015 at the University. All patients underwent LPN performed by an experienced laparoscopic surgeon. The demographic, perioperative and postoperative parameters were compared between the groups, and the effect of both suture techniques on the warm ischemic time (WIT) and trifecta were evaluated. Results: The running suture renorrhaphy with Monocryl (R) reduced WIT, estimated blood lost and length of hospitalization stay significantly without increasing postoperative complication rate during LPN in comparison with interrupted knot-tying suture. Conclusion: The renorrhaphy using the running suture with Monocryl (R) is an effective and safe technique with the advantage of shortening WIT even in more challenging and larger tumors during LPN.
