In 1977, a controlled, prospective trial was initiated to test the hypothesis that excessive enterogastric (EG) reflux was responsible for a unique postgastrectomy syndrome, "alkaline reflux gastritis." Late (42 +/- 3 months) follow-up on all treated patients (N = 14; Rx = 45 cm Roux Y limb) is reported. The following parameters were assessed in symptomatic (N = 11 nonrefluxers, 15 refluxers) and asymptomatic postgastrectomy patients (N = 9): CCK-stimulated scintographically determined EG reflux (EGRI %), intragastric (IG) concentration of bile acids (BA, mM), net bile acid reflux/hr (microM), maximum acid output (mEq/hr), intragastric pH, gastric emptying of 99Tc-labeled solids (T 1/2; minutes), gastritis score (GS = 0-15), and specific symptomotology. A significant linear relationship was noted between intragastric BA concentration and the severity of histologic gastritis in the residual gastric pouch. As a group, excessive refluxers demonstrated significantly greater IG BA concentration, net BA reflux/hour, and EGRI than did either nonrefluxers or controls. Gastritis score in this group was also greater, intragastric pH higher, and maximal acid output (MAO) lower. Gastric emptying was not different between groups. Following Roux (N = 14), reflux was eliminated early and late, pH fell, MAO increased, and gastritis improved. Early marked delays in emptying occurred but normalized late and were rarely a clinical problem. Early symptomatic results were pain eliminated in 14/14, nausea in 8/14, vomiting 11/14, bilious vomiting in 14/14. Complications were one marginal ulcer (no vagotomy), two severe delays in emptying (simultaneous Roux + vagotomy). Late symptomatic results were recurrent or persistent pain in 4/14, nausea in 7/14, vomiting in 5/14. Bilious vomiting remains eliminated.

The authors present the case of a 43-year-old women who underwent a laparoscopic gastric bypass in 2003 for morbid obesity. They report that 2 years later, she had maintained significant weight loss, but had developed acute abdominal pain, followed by nausea and emesis. In the emergency room, she had diffuse tenderness, tachycardia, and leukocytosis. After initial resuscitation, a computed tomography was performed, which showed free air above the liver and thickened small bowel loops. She was brought emergently to the operating room for laparoscopy. At surgery, turbid fluid and inflamed small bowel loops were seen. A perforated marginal ulcer was discovered in the Roux limb, approximately 2 cm distal to the gastrojejunal anastomosis. The perforation was oversewn primarily and patched with omentum. The repair was tested by intraoperative endoscopy. A gastrostomy tube also was placed within the gastric remnant for enteral access. The patient did extremely well postoperatively, and had an uneventful postoperative course. She was discharged on postoperative day 4. The gastrostomy tube was removed at 1 month, and at this writing, she remains well since surgery. An upper endoscopy at 2 months was completely normal, and the Helicobacter pylori test results were negative. The gastric pouch had not significantly enlarged since initial surgery, as indicated by both endoscopy and barium study. Marginal ulcer is reported to be 0.6% to 16% after laparoscopic gastric bypass. Etiologies include gastrogastric fistula, excessively large gastric pouch containing antral mucosa, H. pylori infection, nonsteroidal antiinflammatory use, and smoking. Unfortunately, none of these applied to the reported patient. Because her exact etiology remains unknown, she at this writing continues to receive proton pump inhibitor therapy.
