Background and purpose: Laparoscopic endoscopic single-site surgery (LESS) has recently emerged as an attempt to enhance cosmetic benefits and reduce morbidity; however, LESS for radical cystectomy is still not well established. Here we describe the technique of hybrid LESS for radical cystoprostatectomy and orthotopic ileal neobladder (RC-OIN), and evaluate its feasibility and safety.
Patients and methods: Between November 2008 and October 2009, 12 men with bladder cancer underwent hybrid LESS for RC-OIN. A homemade multichannel port, made from two stretchable rings and a surgical glove with trocars and valves attached to its fingers, was placed into a 4- to 5-cm midline incision in the lower abdomen and was used for laparoscopic instruments. Another subumbilical port was placed for the laparoscope. Extended bilateral pelvic lymphadenectomy was performed by the lateral view; radical cystoprostatectomy was completed laparoscopically; construction of the ileal neobladder was performed extracorporeally; and the neobladder was anastomosed to the urethral stump laparoscopically, with a slipknot running suture technique. Perioperative, functional, oncologic data and complications were collected and analyzed.
Results: All operations were performed successfully without conversion to conventional laparoscopic radical cystectomy or open surgery. There was no perioperative mortality or port-related complications. The median operative time was 383 minutes. Median blood loss was 150 mL. A median of 25 lymph nodes were removed. Surgical margins were tumor free in all cases.
Conclusions: Hybrid LESS for RC-OIN is technically feasible with effects similar to those of conventional laparoscopic procedures. Further instrument and technique improvement are necessary to shorten operative time and reduce intraoperative difficulties.
