Abstract
OBJECTIVE
To evaluate the long term oncological and functional outcomes after readaptation of the dorsolateral peritoneal layer following pelvic lymph node dissection (PLND) and cystectomy .
PATIENTS AND METHODS
A randomised, single-center, single-blinded, two-arm trial was conducted on 200 consecutive cystectomy patients who underwent PLND and cystectomy for bladder cancer (<cT4, cN0, cM0) between April 2006 and September 2009. Patients were randomised into two groups: group A with readaptation of the dorsolateral peritoneal layer (n=100; 73 male, 27 female; median age 68 yrs, range 35-86 yrs) and group B without readapation (n=100; 66 male, 34 female; median age 65 yrs, range 30-86 yrs). Regular postoperative follow-up was performed at our outpatient clinic. Median follow-up was 59 months (range 3-100 months), five patients were lost to follow-up in group A, seven in group B. Bowel function was evaluated using the validated Gastrointestinal Quality of Life Index questionnaire and an institutional questionnaire regarding post-cystectomy outcome. Local recurrences and distal metastases were evaluated using computed tomography and bone scan at the regular follow-up visits.
RESULTS
There was no significant difference between the two groups in terms of the rate of local (pelvic) recurrence (5/95 [5.3%] in group A; 7/93 [7.5%] in group B; p = 0.53), the rate of distant metastases (21/95 [22.1%] in group A; 23/93 [24.7%] in group B; p = 0.67), cancer-specific survival (p = 0.37), and overall survival (p = 0.59). Group A had significantly better bowel function at 3 (p < 0.001), 6 (p < 0.006), 12 (p <0.006) and 24 months (p = 0.04), and significantly less postoperative abdominal pain and bloating at 3 (p = 0.002) and 6 months (p = 0.01).
CONCLUSION
Readaptation of the dorsolateral peritoneal layer following PLND and cystectomy has a beneficial long-term impact on bowel function and postoperative pain without compromising oncological radicality. This article is protected by copyright. All rights reserved.
