This 2-center study compares the relative merits of laparoscopic and open surgical internal marsupialization of pelvic lymphoceles. Laparoscopic lymphocelectomy was performed in 12 patients (group 1). The results were compared with open lymphocelectomy performed in 13 contemporary patients (group 2) as well as 13 historical patients (group 3). Operative time was longer in group 1 compared to groups 2 and 3 (194.6 versus 176.9 versus 133.8 minutes, respectively). However, group 1 had a decreased blood loss (23.1 versus 74.6 versus 61.7 ml.), earlier resumption of oral food intake (0.9 versus 2.5 versus 2.1 days), shorter hospital stay (2 versus 6.1 versus 6.3 days) and abbreviated convalescence (2.2 versus 6.9 versus 4.5 weeks) compared to groups 2 and 3. Complications included cystotomy requiring open repair in 1 patient in group 1, prolonged ileus in 1 in group 2, transection of the ureter of a transplant kidney in 1 in group 3 and pneumonitis in 1 in group 3. Lymphocele recurred in no patient in group 1, 4 in group 2 and 3 in group 3. Mean followup in groups 1 to 3 was 12.8, 25 and 54.5 months, respectively. We conclude that laparoscopic lymphocelectomy is effective, results in minimal patient morbidity and allows for a more rapid recovery compared to open surgical lymphocelectomy.
