title: Retroperitoneal drainage after complete Para-aortic lymphadenectomy for gynecologic cancer: a randomized trial.
abstract: OBJECTIVE
  To determine the relationship between retroperitoneal drainage after complete para-aortic lymphadenectomy for gynecologic cancer and subsequent development of lymphocysts.
  
  
  METHODS
  Eighty women undergoing complete para-aortic lymphadenectomy up to the level of the left renal vein for ovarian (n = 43) or cervical carcinoma (n = 37) were randomly assigned to receive drainage or no drainage of the para-aortic area. Most of patients had pelvic drainage. Abdominopelvic ultrasonography was done 8 to 12 days after surgery. Postoperative complications, duration of hospital stay, and characteristics of asymptomatic lymphocysts were studied.
  
  
  RESULTS
  Forty-two women had para-aortic drainage and 38 did not. Complications occurred in 15 patients who had drainage and in 5 patients who did not have drainage (36% versus 13%; P <.02). Three patients (8%) in the undrained group had complications potentially related to drainage (symptomatic lymphocysts or ascites) compared with 11 (26%) in the drained group (chi(2) = 4.6; P <.05). Median duration of the hospital stay was 9 days in the undrained group and 11 days in the drained group (P <.03). The number of asymptomatic para-aortic lymphocysts detected during the ultrasonography was 9 (24%) in the undrained and 2 (5%) in the drained group (chi(2) = 4.6; P <.05).
  
  
  CONCLUSIONS
  The number of asymptomatic para-aortic lymphocysts was higher in patients who did not undergo drainage, but morbidity and the duration of hospitalization were increased in these patients. Routine drainage of the retroperitoneum after para-aortic lymphadenectomy should be abandoned.
