technetium-tc-99m-lidofenin and Peptic-Ulcer

We quantified duodenogastric reflux with 6-hour continuous intravenous infusion of technetium 99m-labeled hepatoiminodiacetic acid (99mTc-HIDA) and subsequent quantification in gastric juice.. For this purpose, 50 patients were studied who had undergone surgery on the stomach with different surgical techniques: bilateral vagotomy plus Heineke-Mikulicz pyloroplasty, bilateral truncal vagotomy plus anterior pylorectomy, proximal gastric vagotomy, antrectomy and Billroth I reconstruction, and antrectomy and Billroth II reconstruction, comparing them with 10 healthy subjects used as a control group. We also studied the existing correlation between the rates of reflux determined by 99mTc-HIDA and those of total bile acids in gastric juice.. Patients who underwent gastric surgery had significantly greater quantities of duodenogastric reflux (p < 0.001) than had the control group. When the groups undergoing gastric surgery were compared, the patients who underwent resection showed higher reflux rates (p < 0.001) than did the patients who did not undergo resection. We found no differences among the groups of patients who did or did not undergo resection. We also found a highly significant correlation (p < 0.001) between the concentrations of 99mTc-HIDA and bile acids in gastric juice.

Postoperative reflux gastritis in persons who were operated on for peptic ulcer occurs much more frequently after resection of the stomach (68.6%) than after organ-preserving operations on the stomach (39.4%). The incidence of reflux gastritis after gastric resection depends on the type of gastroenteroanastomosis. It is encountered much less frequently after Roux' operation (9.2%). The pronounced character and frequency of reflux gastritis after organ-preserving operations on the stomach are determined by the type of stomach-draining operations, the localization of the ulcer before the operation, whether in the stomach or the duodenum, the existence of duodenogastric reflux (DGR) before the operation. Measures for the prevention of postoperative reflux gastritis in the management of peptic ulcer are as follows: (a) wide introduction of organ-preserving operations, preferably SPV by itself or in combination with duodenoplasty; (b) formation of Roux' gastroenteroanastomosis when resection of the stomach is indicated. Reflux gastritis must be treated by nonoperative methods, including medicinal, dietetic, and spa therapy. Surgery is indicated in reflux gastritis combined with other diseases of a stomach which had been operated on, for which an operation is necessary, and in occasional cases of erosive reflux gastritis.

A study of 118 patients, operated on with Billroth II gastrectomy for peptic disease and affected by postgastrectomy syndromes, was carried out. Fifty patients were investigated by means of technetium-99m HIDA hepatobiliary scanning. In 18 patients, in whom an afferent loop syndrome was clinically suspected, hepatobiliary scanning demonstrated an altered afferent loop emptying in 8 and atonic distension of the gallbladder without afferent loop motility changes in 10. Among the patients in the first group, four were treated with a biliary diversion surgical procedure and in the second group, two patients underwent cholecystectomy. Our findings indicate that biliary vomiting, right upper abdominal pain pyrosis, and biliary diarrhea in Billroth II gastrectomized patients are not always pathognomonic symptoms of afferent loop syndrome. Technetium-99m HIDA hepatobiliary scanning represents the only diagnostic means of afferent loop syndrome definition. A differential diagnosis of abnormal afferent loop emptying and gallbladder dyskinesia is necessary for the management planning of these patients, and furthermore, when a surgical treatment is required, biliary diversion with Roux-Y anastomosis or Braun's biliary diversion seems the treatment of choice for afferent loop syndrome, whereas cholecystectomy represents the best procedure for atonic distension of the gallbladder.
