Continent gastric tube: new techniques and long-term followup.
OBJECTIVE
The successful use of stomach for bladder augmentation and substitution is well documented. Gastric tissue has been used more recently to create continent catheterizable tubes. We describe 2 new techniques of gastric tube construction, and report our long-term followup of catheterizable gastric tubes in children and adults undergoing complex urinary tract reconstruction.


METHODS
A retrospective chart review of 6 male and 4 female patients 5 to 43 years old was done. Primary diagnoses included bladder exstrophy, cloacal exstrophy, rhabdomyosarcoma and neurogenic bladder. Five patients underwent gastrocystoplasty with simultaneous creation of a continent gastric tube from the anterior gastric flap. In 2 patients who had undergone previous gastrocystoplasty a continent gastric tube was created from an anterior flap raised from the existing gastric bladder. Isolated gastric tubes were constructed in 3 patients.


RESULTS
Followup ranged from 2 to 9 years (median 3.5). All patients demonstrated easy reliable catheterization. One patient required revision of the proximal end of the tube for incontinence. At followup all tubes were continent. Complications occurred only in flush or protuberant stomas, and resolved after stomal revision with recessed skin flaps.


CONCLUSIONS
Several techniques can be used to create a continent gastric tube. Long-term followup reveals reliable catheterization and good continence rates. Recession of the gastric tube stoma with a skin flap prevents peristomal complications.
