Feasibility of extraperitoneal laparoscopic para-aortic and common iliac lymphadenectomy

Objective.: The aim of this study is to evaluate the feasibility of extraperitoneal laparoscopic para-aortic and common iliac lymphadenectomy for cervical and endometrial carcinoma. Methods.: Seventy-six patients underwent extraperitoneal laparoscopic para-aortic and common iliac lymphadenectomy between February 1999 and September 2005. The lymph nodes dissected with the laparoscopic procedure included the inframesenteric para-aortic lymph nodes, the sacral lymph nodes, and the bilateral common iliac lymph nodes. The extraperitoneal laparoscopic operation was performed with pelvic open surgery using Lap Disc to ensure the safety of patients. Results.: The number of patients with cervical and endometrial carcinoma was 36 and 40, respectively. The median age of patients was 51 years (range 24-75 years). Conversion to open surgery was necessary in 8 patients. These include 3 patients who encountered blood loss of 400, 136 and 128 ml; 2 extremely obese women; and 3 patients who had peritoneal tears causing CO₂ gas leakage. Among the remaining 68 patients, the median operating time for extraperitoneal laparoscopic para-aortic and common iliac lymphadenectomy was 75 min (range 45-145 min), and the median estimated blood loss was 5 ml (range 5-138 ml). The median total number of resected nodes was 14 (range 2-31), and 4 patients had lymph node metastasis. No patient encountered postoperative complications attributable to extraperitoneal laparoscopic para-aortic and common iliac lymphadenectomy. Conclusions.: Extraperitoneal laparoscopic para-aortic and common iliac lymphadenectomy with pelvic open surgery using Lap Disc is a feasible procedure, particularly in the surgeons learning phase.
