[Radionuclide study of gastric emptying in patients who have undergone Roux-en-Y gastrojejunostomy for postoperative alkaline gastritis].Rev Esp Med Nucl. 1998; 17(5):358-64.RE
Roux-en-Y reconstruction is a widely used surgical procedure to reduce the postoperative gastritis secondary to biliary reflux (POGBR). Some studies have shown that after applying this technique, certain symptoms, called Roux stasis syndrome, ocurred. They seem to be caused by a delayed gastric emptying. The aim of the survey is to evaluate that emptying. Three groups have been studied: Group 1: 15 patients with POGBR after Billroth II and Roux-en-Y diversion. Group 2: 15 patients after Billroth II without POGBR. Group 3: 15 healthy volunteers. The gastric emptying after a 99mTc-DTPA-meal was performed in every patient. The stadistical study from the T1/2 emptying showed no significative differences between group 1 before and after Roux-en-Y procedure, nor between these and group 2 and 3. The gastric emptying study does not demonstrate that Roux-en-Y delays it, so it is not the reason of Roux syndrome.
