  • Title: [Stomach emptying after stomach resection with and without retention of duodenal passage].
    Author: Walgenbach S, Junginger T, Eissner D, Hahn K, Schicketanz KH, Schrezenmeir J.

    Abstract:
    On domestic pigs 2/3 gastrectomies with retention and elimination of the duodenal passage were carried out. Postprandial gastric emptying was measured scintigraphically for 4 h and compared with a control group (laparotomy only). For the semi-solid, 99mTc-labeled test meal delayed gastric emptying after elimination of the duodenal passage by Roux reconstruction could not be shown. There was no difference in gastric emptying between B-I and Roux-en-Y partial gastrectomy. Also alteration of the length of the jejunum loop from 40 to 20 cm after Roux-en-Y reconstruction had no influence on gastric emptying. Roux reconstruction (40 cm loop) in combination with truncal vagotomy led to a non-uniform gastric emptying, but there was a statistically proven acceleration compared with B-I resection. After 240 min the mean residual intragastric activity of the control group (n = 5) was 47.8%, 78.9% after B-I resection (n = 5), 59% after Roux reconstruction with 40 cm jejunal loop (n = 5), 38.1% after Roux reconstruction with 20 cm jejunal loop (n = 5) and 20.9% after Roux-en-Y (40 cm loop) with truncal vagotomy (n = 4).
