Document Summary

Resection of part of stomach (partial gastrectomy) and pylorus. Alternative to pyloroplasty; gastric remnant anastomosed to small intestine. Anastomosis of proximal end of duodenum to distal end of remnant stomach. Anastomosis of remnant stomach to side of jejunum blind duodenal loop (stapled) to allow for bile and pancreatic secretions to flow into intestine (aid digestion and absorption) Jejunum pulled up and anastamosed at distal end of esophagus or gastric remnant. Duodenum then connected to small bowel to allow bile and pancreatic secretions to flow into the intestine. From effects of anaesthetic or manipulation of organ. Patients remain npo or on fluid diet is gastric emptying slowed. Enteral support can bypass a gastric ileus vi nasoenteric tube. Dumping syndrome: size of stomach, regulatory mechanisms and pyloric sphincter function all altered. Physiological response to presence of larger-than-normal amounts of food and liquid in small intestine. Enters duodenum slowly via pyloric sphincter; acidic chyme is neutralized by pancreatic bicarbonate.
