title: Double-barreled wet colostomy: a safe and simple method after pelvic exenteration.
abstract: The clinical and functional outcome of ureteric division to the distal segment of a loop colostomy: the double-barrelled wet colostomy have been analysed.
  
  
  METHODS
  13 patients (8 female and 5 male, age 37 to 72 years) underwent pelvic exenteration with double-barrelled wet colostomy. The primary tumour included endometrial (n = 6), rectal (n = 1), anal (n = 1), cervical (n = 2), prostatic (n = 1) and bladder (n = 2). Indications for pelvic exenteration were locally advanced disease, recurrence and severe radiation or surgical damage. Six patients had pre-existing colostomy, and three had a Bricker ureteroileal diversion. The double-barrelled-wet colostomy technique consisted in anastomosing both ureters to a colon segment 25 cm distal to the loop colostomy. There was no operative mortality. Complications included one urinary leak which closed with conservative management and one case of recurrent episodes of pyelonephritis which finally required nephrectomy. Intravenous urography in the remaining patients showed good flow through the ureters to the conduit with no reflux. Postoperative plasma electrolytes, urea and creatinine were normal from day seven onwards. Urodynamic studies in four patients showed efficient contraction of the colon conduit with pressure levels similar to those in the colon proximal to the colostomy. In five cases biopsies of the conduit were taken at 3 and 16 months; no dysplasias were found. Four patients died due to disease progression. The overall mean survival was 41.2 months. The remainder are currently disease-free, maximum followup period being 19 months. Double-barrelled wet colostomy is a safe and simple technique with low morbidity. The patient needs to carry only one stoma and functional results are good.
