A 21-year-old woman presented gastrointestinal manifestation showing intermittent abdominal pain, nausea, and vomiting. An upper endoscopic examination showed round, elevated mucosa at the antrum of the stomach anterior wall. After CT scanning, a huge degenerated gastrointestinal stromal tumor was suspected. Subtotal gastrectomy with Billroth II anastomosis was performed. Histologically, pseudo...

A 49-year-old man was referred for management of weight regain 3 years after Roux-en-Y gastric bypass (RYGB) surgery. He had gained 14kg in weight in the previous 6 months. Upper endoscopy revealed a 35-mm gastrojejunal anastomosis. Three sessions of transoral gastric outlet reduction over 7 months using endoscopic suturing (OverStitch; Apollo Endosurgery, Austin, Texas, USA) had not resulted i...

adenosquamous carcinomas of stomach are rare entities comprising 0.5% of stomach carcinomas. here, we report a case of a 50-year-old female, who presented with weakness, pallor, and symptoms of gastric outlet obstruction. a partial gastrectomy was done and histology showed evidence of adenosquamous carcinoma of the antrum with metastasis to the perigastric lymph nodes. the patient condition imp...

bezoars are concretions of foreign materials that impair gastrointestinal motility or cause intestinal obstruction in the stomach, small intestine or bowel of humans or animals. there are many types of them such as phyto, lacto and trichobezoars. although bezoars are not rare, multiple giant bezoars which totally fill the stomach lumen and have extension to the small intestine (rapunzel syndrom...

Amyloidosis is an abnormal extracellular deposition of insoluble proteins, which is associated with an involvement of the gastrointestinal tract in 50 to 70% of cases. In primary amyloïdosis (light chain amyloïdosis), localized gastric involvement is a rare finding which can mimick malignancy. We report the case of a 75-year-old woman, admitted with upper digestive outlet obstruction and genera...

Hypertrophic pyloric stenosis (HPS) is a well-known cause of gastric outlet obstruction in infants. However, its etiology is still controversial. Our experience has let us to consider that transpyloric (TP) tube feeding may be a potential cause of HPS. We report 3 cases of HPS in the context of TP tube feedings. All 3 patients had severe fundamental surgical disease and required enteral nutriti...

Hyperplastic gastric polyps are incidentally diagnosed during upper gastrointestinal endoscopy. They are known to cause gastric outlet obstruction and chronic blood loss leading to iron deficiency anemia. However, hyperplastic gastric polyp presenting as acute severe upper gastrointestinal bleeding is very rare. To the best of our knowledge, there have been two cases of hyperplastic gastric pol...
