[Adult intestinal heterotopic gastric mucosa resulting in alimentary tract hemorrhage: a report of 11 cases].

OBJECTIVE
To investigate the clinical characteristics,diagnosis and treatment of intestinal heterotopic gastric mucosa resulting in alimentary tract hemorrhage.


METHODS
Eleven cases of intestinal heterotopic gastric mucosa with alimentary tract hemorrhage during the past 24 years in our hospital were reviewed and the clinical data were analyzed retrospectively.


RESULTS
The median age was 29 years old. Nine cases had abdominal pain, and radionuclide (99m)Tc-pertechnetate scan revealed bleeding lesion in 6 cases preoperatively. Segmental resection of the intestine with bleeding lesion were performed in all patients, postoperative pathology confirmed heterotopic gastric mucosa. The lesion was located in the jejunum in five cases and in the ileum in six cases. All lesions were complicated with diverticulum, or inflammatory mass on the intestinal wall, or abnormity of intestinal duplication.


CONCLUSIONS
Intestinal heterotopic gastric mucosa is difficult to be diagnosed preoperatively, and radionuclide (99m)Tc-pertechnetate scan plays a role in preoperative diagnosis.
