Other case reports have documented CT findings such as foreshortening and narrowing of the gastric antrum, converging or telescoping of mucosal folds in the antrum or duodenum, prepyloric
outpouchings, widening of the pylorus and duodenum, or an intragastric filling defect (4, 10).
The common sites of bleeding must be visualised--that is the distal oesophagus, the incisura of the stomach, the prepyloric
region and the first part of the duodenum.
We report a case of prepyloric gastric perforation due to Ascaris.
A 1 cm x 1cm perforation was found in the prepyloric region of stomach and two live Ascaris were seen protruding through the perforation (Figs 1 and 2).
In the first quarter of the 20th century, two thirds of gastric cancers were located in the antrum and the prepyloric
area, and only 10 per cent arose in the cardia or the oesophagogastric junction.
Pancreatic heterotopia is most common in the duodenum, the upper jejunum, and the stomach (typically the prepyloric
region, the greater curvature, and the posterior wall).
Endoscopic studies have demonstrated that NS-NSAIDs classically produce shallow erosions or submucosal hemorrhages that can occur at any site in the alimentary tract, but are observed more commonly in the stomach near the prepyloric
area and the antrum.
Differing patterns of Helicobacter pylori gastritis in patients with duodenal, prepyloric
, and gastric ulcer disease.
The upper gastrointestinal series disclosed polypous masses in the bulb and the prepyloric part of the stomach (Figure 2).
During the laparotomy, a prepyloric intraluminal tumour was found, and a Billroth II resection was performed.
The patient underwent surgery during which 4 subserosal gastric lesions located on the fundus and 1 prepyloric
tumor located along the lesser curvature were noted.
