Delayed gastric emptying after Roux-en-Y due to four types of partial obstruction.
Partial obstruction was the cause of delayed gastric emptying in 12 patients after a Roux-en-Y gastrojejunostomy in a consecutive personal series of 42 patients between 1975 and 1989. Four types of obstruction were identified. Type I was due to a kinked loop of jejunum where it passed through the mesocolon. Type II had the anastomosis too high on the gastric pouch, type III was due to an obstructing marginal ulcer, and type IV had a pouchlike deformity develop in the upper jejunum at the anastomosis that gradually compressed the outflow tract. No patient had stenosis of the anastomosis. The upper gastrointestinal (GI) series plus nuclear studies of the liquid and solid phase gastric emptying provided evidence of the presence and degree of delayed gastric emptying but not the site or cause of the obstruction. Upper GI endoscopy provided precise evidence of the site of the partial obstruction, its anatomic nature, and the presence of a bezoar or marginal ulcer. Of the 42 patients, 4 had surgical correction, and in 6 patients the obstruction was relieved by endoscopic manipulation; all patients have been relieved of their symptoms. Partial obstruction was the only cause of delayed gastric emptying in this series, and contrary to recent reports, no patient required a total or near total gastrectomy.
