Complications of Laparoscopic Pelvic Lymph Node Dissection

Abstract

Intraoperative and postoperative complications were assessed in the first 372 patients undergoing laparoscopic pelvic lymph node dissection at 8 medical centers. In 16 patients laparoscopic node dissection could not be completed due to patient body habitus or technical difficulties. Of these aborted procedures 14 occurred during the initial 8 dissections at each institution. A total of 55 complications (15%) occurred: 14 were noted in the intraoperative and 41 in the postoperative period. Of these patients 13 required open surgical intervention for the treatment of a complication. Complications included vascular injury (11 patients), viscus injury (8), genitourinary problems (10), functional/mechanical bowel obstruction (7), lower extremity deep venous thrombosis (5), infection/wound problem (5), lymphedema (5), anesthetic complications (2) and obturator nerve palsy (2). Based on our experience, there is a significant learning curve associated with performing laparoscopic pelvic node dissection. However, with experience and adherence to laparoscopic surgical principles, the risk of complications may be minimized.
