Abstract:
Ten patients with benign gastric or duodenal disorders were consecutively included in the protocol evaluation of gastric emptying after the "uncut" Roux en Y to prevent the Roux en Y syndrome. There were no clinical complications. Its performance was not more complex from a technical viewpoint, and its morbility could be less that in other procedures. There are 2 important objections to the development of this procedure. First, the gastric emptying study shows no difference with the traditional Roux en Y emptying. And second, a definitive closure of the afferent fold is not achieved with the non-cutting linear stapling, the endoscopic control 6 months after surgery showing repermeation of the fold in 80% of the patients. The use of the technique was brought to a halt for its results were outside the standards of the protocol.
