In rare cases with multiple gastric polyps in the corpus and fundus, a recently described gastric polyposis syndrome called gastric adenocarcinoma and proximal polyposis of the stomach (GAPPS) has to be considered. We report on the findings in a patient fulfilling the criteria of this disease.A female patient born in 1977 underwent gastroscopy in 2005 due to recurrent abdominal pain. Endoscopy revealed more than 100 fundic gland polyps in the corpus and fundus. An ileocolonoscopy was inconspicuous. The patient did not take proton pump inhibitors...

Neoplastic lesions of gastric adenocarcinoma and proximal polyposis of the stomach (GAPPS) are gastric phenotype. GAPPS was reported in 2011 as a new autosomal dominant gastric polyposis syndrome characterized by involvement of the gastric body/fundus with sparing of the antrum by multiple polyps, reported to be primarily fundic gland polyps (FGPs), with progression to dysplasia and adenocarcinoma of intestinal type. Our series consists of 51 endoscopic biopsies and 5 gastrectomy specimens from 25 patients belonging to a previously defined GAPPS family...

Heterotopic gastric mucosa (HGM) is a rare anomaly in the small bowel and may be the cause of intussusception when it gets a lead point in the jejunum. All cases of intussusception due to intestinal HGM have been treated with surgical resection. A 5-year-old girl presented with chief complaints of vomiting and abdominal pain for 2 weeks. A computed tomography scan of the abdomen showed intussusception at the proximal jejunal loops. Three air reductions and one saline reduction were attempted without success...

A 67-year-old man presented with food impaction and was found to have a gastric polyp obstructing the esophageal outlet. Due to the polyp's location and size, no immediate endoscopic intervention was performed, and the patient returned for intraoperative endoscopy and polypectomy. Cases of gastric polyps causing esophageal obstruction have not been identified in the literature. This case is unique for the location and size of the polyp, necessitating concomitant surgical management.

Purpose of review Benign epithelial gastric polyps, although typically asymptomatic, are identified incidentally on upper endoscopy in up to 23% of patients. These include fundic gland, hyperplastic, and adenomatous polyps. Their appropriate characterization is critical as some have malignant potential, may be indicative of a gastric mucosal field defect, or may be related to an underlying polyposis syndrome. This review will discuss the current management of benign epithelial gastric polyps. Recent findings Association of gastric polyps with proton pump inhibitor use, Helicobacter pylori infection, risk of malignant transformation, and association with polyposis syndromes have been the focus of recent literature...

Gastric precancerous diseases (GPD) may deteriorate into early gastric cancer if misdiagnosed, so it is important to help doctors recognize GPD accurately and quickly. In this paper, we realize the classification of 3-class GPD, namely, polyp, erosion, and ulcer using convolutional neural networks (CNN) with a concise model called the Gastric Precancerous Disease Network (GPDNet). GPDNet introduces fire modules from SqueezeNet to reduce the model size and parameters about 10 times while improving speed for quick classification...

RATIONALE: Cronkhite-Canada Syndrome (CCS) is an idiopathic, nonhereditary syndrome haracterized by gastrointestinal (GI) polyposis and ectodermal changes including alopecia, onychatrophia, and pigmentation. CCS colon polyps were previously considered to be benign neoplasms. However, serrated adenoma was reported to be associated with malignant neoplasms in some cases of gastric and colorectal carcinomas, and esophageal cancers. Although malignant colon and gastric cancer have been reported in CCS, reports of distant metastasis have been rare in CCS...

Proton-pump inhibitors (PPIs) are the most effective therapy for the full spectrum of gastric-acid-related diseases. However, in the past decade, a steadily increasing list of complications following long-term use of PPIs has been reported. Their potent acid-suppressive action induces several structural and functional changes within the gastric mucosa, including fundic gland polyps, enterochromaffin-like cell hyperplasia and hypergastrinaemia, which can be exaggerated in the presence of Helicobacter pylori infection...

Objective The long-term use of proton pump inhibitors (PPIs) may induce adverse events in many organs, including the stomach. The chronic use of PPIs has been associated with the growth of fundic gland polyps (FGPs) and of gastric black spots. This study assessed the incidence of gastric lesions with cobblestone-like appearance in PPI users. Methods The clinical characteristics and endoscopic findings of patients who underwent upper gastrointestinal endoscopy after using PPIs for at least six months were analyzed...

Plexiform fibromyxoma is a very rare mesenchymal tumor of the stomach, found almost exclusively in the antrum/pylorus region. The most common presenting symptoms are anemia, hematemesis, nausea and unintentional weight loss, without sex or age predilection. We describe here two cases of plexiform fibromyxoma, involving a 16-year-old female and a 34-year-old male. Both patients underwent complete resection (R0) by distal gastrectomy and retrocolic gastrojejunostomy (according to Billroth 2); for both, the postoperative course was uneventful...

With the increasing popularity of sleeve gastrectomy, many stomach specimens are being evaluated. Understanding the significance and treatment for unexpected pathology is important. This study examines the incidence of relevant histopathology of sleeve gastrectomy specimens. It evaluates previous data for each histopathology and provides recommendations for treatment. In this study, a retrospective review was performed for 241 patients who underwent sleeve gastrectomy from 2009 to 2014 at a single institution...

We present a rare case of a big oesophageal liposarcoma causing dysphagia and weight loss in a 75-year-old patient. Endoscopically, a pedunculated lesion with subtotal obstruction of the oesophageal lumen had been detected and thoracoabdominal oesophageal resection with gastric sleeve reconstruction was performed. Surprisingly, a liposarcoma of the oesophagus was revealed on histopathological analysis, showing MDM2 overexpression. Oncological follow-up has been uneventful and the patient remains in good clinical shape at 15 months after surgery...

Gastric polyps include a wide spectrum of lesions with different histology and neoplastic potential. They are found in up to 6% of upper gastrointestinal endoscopy and are usually asymptomatic and incidentally diagnosed, being in the vast majority epithelial gastric polyps. Hyperplastic, fundic gland and adenomas are the most common types of gastric polyps and, although each type may have typical endoscopic appearances, they all must be sampled at the initial endoscopy for histological assessment. Also, the normal appearing gastric mucosa should be sampled to stage atrophic changes, rule out endoscopically non-visible dysplasia and to diagnose Helicobacter pylori...

The early Cambrian problematica Xianguangia sinica, Chengjiangopenna wangii, and Galeaplumosus abilus from the Chengjiang biota (Yunnan, China) have caused much controversy in the past and their phylogenetic placements remain unresolved. Here we show, based on exceptionally preserved material (85 new specimens plus type material), that specimens previously assigned to these three species are in fact parts of the same organism and propose that C. wangii and G. abilus are junior synonyms of X. sinica Our reconstruction of the complete animal reveals an extinct body plan that combines the characteristics of the three described species and is distinct from all known fossil and living taxa...

Although gastrointestinal stromal tumors (GISTs) comprise less than 1% of all gastrointestinal (GI) tract tumors, they are the most common mesenchymal tumors of the GI tract. Gastrointestinal stromal tumors can occur anywhere along the GI tract, but the stomach and small intestine are the most frequently involved sites. Gastrointestinal stromal tumors are frequently asymptomatic, and one-third of all cases are found incidentally. Endoscopy, endoscopic ultrasonography, and computed tomography are useful tools in the diagnosis...
