In this video we present the laparoscopic technique for appendico- vesicostomy, using trans-umbilical approach, 3 mm instruments, two working ports, and a modified Shanfield anastomosis. MATERIAL AND METHODS A 5-year old boy with large residuals and hematuria was diagnosed as non-neurogenic neurogenic bladder and was suitable for a Mitrofanoff-channel formation. Technique: The procedure is performed using a transperitoneal three-port approach. A 30-degree camera is inserted through a 5 mm trans-umbilical port. Two 3 mm working ports are triangulated to achieve optimal access to the appendix and bladder. The caecum is mobilised adequately.Atransab- dominal 2/0 PDS hitch stitch elevates the bladder. Posterior detrusorotomy and submucosal dissec- tion follows. The appendix is detached from the colon preserving its pedicle. The proximal appendix is spatulated for 5 mm, pulled through a hiatus created in the distal vesical mucosa into the bladder using a U-stitch and fixed. Three additional stitches between the bladder mucosa and the appendix serosa secure the anastomosis. Closing the detrusor muscle, with a 10Fr Jacques catheter in the conduit, creates an anti-refluxing extra-mucosal tunnel. The tip of the appendix is brought out to the right iliac fossa and a VQ-plasty is fashioned. RESULTS The procedure was completed in 4 hours. Postoperative analgesia was provided with Fentanyl- NCA up to post-op day-4, paracetamol and oxybutynin. Oral intake was established on day-1 and the patient was discharged on day-5 without any complications. CONCLUSIONS The laparoscopic appendico-vesicostomy can be facilitated with minimal number of ports and the transumbilical approach utilises a natural scar. The anastomosis is simplified and the catheterisa- tion is reliable as there is no mucosa-mucosa junction to negotiate. 13:24–13:36 Discussion
