Aim: Duodenogastric reflux is a common healthy problem and duodenal switch (DS) has been found to be a 
useful operation for treatment of this abnormal primary and pathologic problem.
Objective: Assessment the efficacy of the duodenal switch procedure as a treatment option for primary and 
pathologic duodenogastric reflux (DGR).
Methods: Over a period of 3 years, 6 patients with symptomatic primary DGR and 14 patients with 
pathologic DGR following gastrojejunostomy underwent pancreaticobiliary diversion using duodenal switch 
procedure. Endoscopic evaluation of gastric and duodenal mucosa was done before and after surgery. 
Symptoms were evaluated with a symptom score using a detailed questionnaire. Suprapapillary 
duodenojejunostomy (duodenal switch procedure) was done in all patients.
Results: During a mean follow-up period ranging from 6-34 months with a mean 24 months, most of the 
patients had a good satisfactory outcome as defined by endoscopic evaluation and significant reduction in 
the pre-operative symptoms. There was no reoperation or mortality in our study.
Conclusion: The duodenal switch procedure is an effective surgical therapy in patients with primary or 
pathologic or DGR.
