The effect of proximal gastric vagotomy plus duodenoplasty on duodenogastric reflux.
Alkaline reflux gastritis is a clinical syndrome that results from a mucosal injury by duodenal contents. In this study, the amount of duodenogastric reflux was assessed in patients who previously underwent proximal gastric vagotomy (PGV group; n = 11) and PGV plus duodenoplasty (PGV+D group; n = 10) as a treatment for duodenal ulcer. The control group (A) consisted of 11 healthy volunteers without endoscopic abnormalities. A quantitative index of duodenogastric reflux was obtained in each case by determining the percentage of the injected dose of 99mTechnetium-DISIDA that was recovered by continuous aspiration of gastric juice in fasting subjects. In the PGV group, the percentage of administered 99mTechnetium-DISIDA recovered from the stomach (median: 0.69%; range: 0.09%-3.61%) did not differ significantly (P > 0.05) from that of the PGV+D group (median: 0.49%; range: 0.09%-3.91%) and from that of the A group (median: 1.47%; range: 0.22%-3.01%). The results show that proximal gastric vagotomy plus duodenoplasty did not increase duodenogastric reflux.
