“…The salient feature of our technique is the placement of an intraluminal Foley catheter with the balloon distended to facilitate dissection. This was reported by Lima et al 11 claiming that this allowed the surgeon to enter the correct plane preventing intestinal regrowth. We entirely agree with their observation and ourselves found that the Foley balloon behaved like a “mucophilic” device attracting the mucosa to it.…”

“…In their first report, they isolated a segment of the colon and injected saline between the layers of the mucosa and the submucosa to achieve demucosalization from the exterior 10 . In subsequent work, they used a Foley catheter inside the lumen to facilitate dissection and then retrieved the mucosa and excised it via the rectum 11 . Hafez et al 12 adapted this technique, but instead used hydrodistension of the colonic segment to facilitate the extraluminal dissection.…”

ObjectiveTo develop a robust sterile, fully demucosalized and vascularized seromuscular patch for use as an adjunct to novel bioengineering techniques aimed at augmenting, reconstructing, or replacing the bladder because of endstage disease. To eliminate deep colonic epithelial crypts to prevent the possibility of colonocyte regrowth. To maintain sterility by excluding the possibility of contamination from the bowel contents.MethodsPilot studies were performed on euthanized pigs to optimize the technique, with tissue samples examined by immunohistochemistry. In vivo, vascularized seromuscular colonic flaps were created from the bowel exterior in 7 large white hybrid pigs. The dissection was facilitated by placing an inflated Foley catheter within the colonic lumen. The seromuscular ends were approximated with 5/0 Vicryl sutures and excess mucosa intussuscepted within the lumen. Demucosalized flaps were used to augment the bladder by composite cystoplasty and were examined immunohistochemically at 3 months.ResultsPilot studies showed that the technique was successful in creating seromuscular segments with no epithelial remnants. When applied surgically, the seromuscular flaps survived and showed no evidence of colonocyte regrowth at 3 months.ConclusionExtraluminal dissection creates robust seromuscular flaps and prevents both regrowth by colonic epithelial cells and contamination of the tissue by exposure to the bowel contents. This technique should find application in a range of bladder reconstruction techniques, including composite cystoplasty and autoaugmentation.

The Evolution of Bladder Augmentation: From Creating a Reservoir to Reconstituting an Organ

Bladder augmentation was first described in 1899. The goal at the time was to establish the ideal method to create a simple capacious reservoir for the safe storage of urine. That simple idea has over the last 100 years grown into one of the most dynamic areas in Pediatric Urology. Creative minds and hands from individuals in multiple disciplines have led us from creating a reservoir to the threshold of recreating a functional organ. In this review, we look at the historical evolution of bladder augmentation and how it exponentially grew in scope from those initial descriptions of intestinocystoplasty to the work being reported today in the field of tissue engineering.

“…Studies using intravesical silicone balloons after autoaugmentation showed an increase of 329% in bladder capacity and a sevenfold increase in compliance. 6 The present study assessed the different surgical techniques for laparoscopic bladder autoaugmentation with and without the use of the intravesical silicone balloon in dogs so that future experiments can better evaluate this promising procedure.…”

Nonsecretory Intestinocystoplasty: A 10-Year Experience

Abstract: Based on our study we conclude that demucosalized intestine is a safe alternative for bladder augmentation and can be used for the same indications as total bowel segments.
