Lymphocele formation after extraperitoneal pelvic lymphadenectomy: possible predisposing factors.
A retrospective review of 61 patients undergoing pelvic lymphadenectomy was performed to assess possible predisposing factors for lymphocele development. The procedure was done to facilitate staging of prostatic carcinoma in all of the patients. The complication occurred in 9 patients (14.8 per cent). Analysis revealed a statistically significantly higher incidence of lymphoceles in patients without drainage (p less than 0.05) and in patients whose lymph nodes had no metastatic disease (p less than 0.025). Furthermore, 9 patients (without drainage and with nodes that were free of tumor but who received mini-dose heparin therapy) as a subgroup had the highest incidence of lymphocele formation. Although these individual factors have been attributed to this complication after lymphadenectomy they may act synergistically.
