Modified Benchekroun technique for continent ileal stoma.

The Guzman continent ileal stoma is constructed by a modification of the Benchekroun technique, which is based on the principle of the inkwell and collapse of the inner tube through retrograde filling of the valve. We used this procedure in 7 patients, all of whom are continent. During a followup of 6 months to 2 years no major complications developed. The stoma is easy to construct, has a low risk of evagination because the inner tube is stabilized with sutures and is easy to catheterize. It does not require staples, which reduces the chance of stone or fistula formation. The terminal ileum in continuity with the cecum or an isolated ileal segment can be used.
