[The radiological study of duodenogastric reflux following surgery for perforated duodenal ulcers].

Radiologic aspiration method (99mTc-bound with EHIDA-148 MBq) was used for quantitation of duodenogastric reflux, 3 months after operations for perforated duodenal ulcers. The patients were divided in three groups of 10 each: gr. II--after simple suturing; gr. III--after truncus vagotomy and Heinecke-Mikulicz pyloroplasty and gr. IV after proximal selective vagotomy and rrhaphy. The results were compared with those in a group of practically healthy patients (gr. I). The radioactivity of the gastric aspirate was measured between the 30. and the 60. min at 15 min interval. It was found that proximal selective vagotomy with rrhaphy had minimal duodenogastric reflux and there was no difference with practically normal subjects. Truncus vagotomy was associated with significant duodenogastric reflux. Similar were the results with simple suturing.
