[Morphofunctional evaluation of the results of reconstructive operations of gastroenteroanastomosis in peptic ulcer].
The mucosa of the gastric stump, abducting and adducting loops of small intestine in patients with peptic ulcers of gastrointestinal anastomosis has been examined with scanning, transmission electron and light microscopy, morphometry, and the study of secretion at various periods after reconstructive surgery combined with vagotomy. An increase of the number of chief and parietal cells in the gastric stump fundal glands, increase of the thickness of the mucosa due to the deepening of the crypts of the adducting and abducting loops of the small intestine, and alteration of the mucosal microrelief of the gastric stump and small intestine are noted in peptic ulcers of gastrointestinal anastomosis especially near the site of anastomosis. This is accompanied by an increase of mucosal secretory activity. Reconstructive operations combined with vagotomy cause a reduction in chief and parietal cells number, smoothing of the mucosal microrelief and decrease of gastric secretory activity.
