title: Transperitoneal laparoscopic excision of primary seminal vesicle benign tumors: surgical techniques and follow-up outcomes.
abstract: OBJECTIVE
  To assess the feasibility, safety, and efficacy of transperitoneal laparoscopic excision of primary seminal vesicle benign tumors (SVBTs) and summarize our experience with surgical techniques and follow-up outcomes of this rare condition.
  
  
  METHODS
  This study included 6 patients who underwent transperitoneal laparoscopic excision of primary SVBTs between June 2005 and April 2011. A 5-port transperitoneal approach was used. The ipsilateral vas deferens was identified in the upper bulge of the retrovesical peritoneal reflection through a transverse approach and was dissected inwardly and used as a guide to the seminal vesicle tumor. Endoscopic Hem-o-lok clips (Teleflex Medical) were applied to control the vascular supply to the tumor base. With the contralateral vas deferens and seminal vesicle preserved, the tumor was removed together with the vas deferens and the adjoining ipsilateral seminal vesicle. The surgical procedures were successful in all 6 patients, without conversion to open surgery. The mean duration of surgery was 70 ± 16 minutes (range, 50-100 minutes), with unremarkable blood loss of less than 50 mL. The mean postoperative hospital length of stay was 5.2 ± 1.6 days (range, 4-8 days). No intra- or postoperative complications occurred. During a mean follow-up period of 42 ± 24 months (range, 12-82 months), all patients remained asymptomatic, with preserved function as reported by the patient, and there was no evidence of recurrence.
  
  
  CONCLUSIONS
  Our study demonstrated that transperitoneal laparoscopic excision of primary SVBTs is a viable option for minimally invasive treatment of SVBT.
