Laparoscopic radical cystectomy with orthotopic ileal neobladder(report of 15 cases) / 中华泌尿外科杂志

ABSTRACT

Objective To present the initial experience and results of the laparoscopic radical cystectomy (LRC) with orthotopic ileal neobladder. Methods Fifteen patients (14 men and 1 women) with invasive bladder carcinoma underwent LRC with orthotopic ileal neobladder.The mean age was 59.5 years(range,39 to 71 years).The LRC with orthotopic ileal neobladder consists of 3 major steps,namely laparoscopic cystectomy,extracorporeal formation of ileal pouch and laparoscopic urethra-pouch anastomosis.With 5 trocars,the surgeon conducted the procedure through the 2 ports on the left side,and the assistants did so on the right side and hold the laparoscope.The bilateral pelvic lymphadenectomy were performed first.The ureters were dissected just outside the bladder.The radical cystoprostatectomy was performed for the male patients.The total bladder, uterus and appendage were removed for the female patient.A 4 to 5 cm median incision in lower abdomen was made to remove the surgical specimens and construct the ileal pouch.A 50 cm ileal loop was taken from the abdominal cavity,isolated,detubularized and reconfigured into “M” shaped pouch with running suture.The anti-refluxing ureter implantation was performed by inserting the 1 cm of ureter into the pouch and suturing them.For the first 4 cases,the urethra-neobaldder anastomosis was completed through the abdominal incision;while for the other 11 cases,the anastomosis was done under the laparoscope. Results The mean duration of surgery was 5 to 10 h with a mean of 6.5 h;the blood loss was 200 to 1000 ml with a mean of 387 ml.During a follow-up of 1 to 11 months,all patients were alive and asymptomatic with normal upper tracts and had no evidence of local recurrence or metastasis.4 to 6 weeks after surgery,all the patients with orthotopic ileal bladder had complete daytime continence,and nocturnal continence was achieved with 2 to 3 times voiding at night. Conclusions This procedure combines the advantages of minimally invasive laparoscopy with the speediness of open surgery.The laparoscopic cystoprostactomy has a magnified clear vision,which makes meticulous manipulation possible,and reduces bleeding,sphincter injury and nerve bundle injury.Shorter time of intestine exposure during the procedure is good for recovery of intestinal function and for reducing postoperative intestinal adhesion.External construction of ileal pouch shortens operation time remarkably.Ileal segment has long and mobile mesentery,thereby can be easily taken out through a small abdomen incision and anastomosed with urethra stump without tension,so it is more suitable for construction of a pouch.
