[Dumping syndrome following selective proximal vagotomy].

The dumping syndrome after selective proximal vagotomy associated with plastic operations on the pylorobulbar zone developed in 69.2% of patients, Jabuley's gastroduodenostomy being most frequently followed by it. In patients with duodenal ulcer complicated by stenosis of the gastric pylorus and who are predisposed to dumping syndrome the operation of choice should be selective proximal vagotomy associated with exclusion of the duodenum and formation of "end-to-end" gastroenteroanastomosis and Y-shaped entero-enteroanastomosis after Roux. The dumping syndrome can be prevented by performing the operation (SPV) at early periods of the disease before developing the pylorobulbar stenosis when no additional draining operations are necessary.
