[Gastric emptying after duodenogastric resection]

The gastric emptying has been studied with 99Tc labelled in 35 patients followed for 2-8 years after duodenogastric resection. All patients had been undergone a gastric resection of 2/3 of stomach. In 18 had been performed a Billroth II (BII) and in 17 a gastrojejunostomy with a Roux-en-Y anastomosis. The jejunal loop had been carried out about 25-35 cm from the Treitz, the mesenteric margin isolated for 2-3 cm and the jejunojejunostomy performed about 50 cm from the gastrojejunostomy. Nobody complained symptoms from altered gastric emptying. In all patients with Roux-en-Y anastomosis there was an intense radioactivity in the new stoma till the 150th minute, and peristaltic activity was valid and coordinated. In patients with BII there was no radioactivity in the new stoma before the 150th minute, and peristaltic activity was always convulsive and uncoordinated.
