[Jejuno-ileal latero-lateral bypass. Defects of mechanical sutures].

In 6 of our patients operated upon for pathological obesity, complete recanalization of the jejunum closed by a mechanical suture upstreams of the jejuno-ileal latero-lateral anastomosis resulted in failure of the intestinal bypass. We have modified our technique and instead of closing the jejunum with a mechanical stapler we now divide it, then bury and attach together its two ends to avoid torsion and invagination. The operation is completed by creating an anti-reflux system at the terminal end of the excluded ileum.
