(11) Some authors believe that Brunner gland adenoma is a distinct preneoplastic lesion with gastric phenotype, nuclear atypia, and immunohistochemical profile identical to the
pyloric gland adenoma of the stomach.
Superficial ulcers and erosions around the GAW and erosive gastritis in the
pyloric antrum were detected.
Majority of cases of CA
pyloric antrum was noted in the age group of 51-60 yrs.
All were non-alcoholic patients with a history of GI tract diseases and/or GI surgeries (1 gastric malignancy, 1 gastritis and
pyloric stenosis, 1 mesenteric ischemia followed by hemicolectomy and small bowel resection, 1 fulminant colitis followed by colectomy and 2 bariatric surgery) (Table 1).
Upper GI endoscopy revealed multiple linear ulcers involving lower 1/3rd of esophagus with white slough, stomach was shortened, thick walled with a growth involving
pyloric opening and first part of duodenum causing narrowing of
pyloric opening in duodenum.
She underwent
pyloric stent placement performed by a gastroenterologist after a
pyloric stricture dilatation procedure 3 months ago.
The prevalence (50%; 95% CI: 27.2%-72.8%) of the Gram negative enteric bacteria observed in the stomach was lower compared to 95% (95% CI: 75.1%-98.9%) prevalence observed both in the small intestine and
pyloric caeca.
A similar technique was adapted for use in benign
pyloric stricture by Hasukic et al.
The patient was referred to interventional radiology for exchange of both jejunostomy and gastrostomy tubes and, during preprocedural evaluation, was noted that the
pyloric stent had migrated proximally into the gastric body and had been inadvertently cannulated by the gastrostomy tube during a prior tube exchange (Fig.
The location of tumor was divided into
pyloric antrum (48.5%, 50/103) and nonpyloric antrum (51.5%, 53/103).
The pathogenesis of delayed gastric emptying is associated with fundus abnormalities, antrum and antroduodenal discoordination,
pyloric dysfunction, and abnormal small bowel motility [3].
The plethora of terminology used in scientific literature to describe these lesions includes "
pyloric gland adenoma," "tubulopapillary adenoma," and "biliary adenoma" [3].
