INTRODUCTION: Prior studies show promising results of the gastric peroral endoscopic pyloromyotomy (G-POEM) procedure for treatment of refractory gastroparesis. One major technical challenge involved in this procedure is identifying the pyloric muscular ring (PMR). The aim of this study is to establish a reliable method for identification of the PMR during G-POEM. METHODS: Fluoroscopy-guided G-POEM was performed by placing an endoclip at the 9 to 11'o clock position at the pylorus for identification of PMR...

OBJECTIVE: Epithelial tumors less commonly occur in the duodenum than in the stomach or large intestine. The clinicopathological characteristics of duodenal epithelial tumors remain a matter of debate. We therefore studied resected specimens to investigate the clinicopathological characteristics of duodenal epithelial tumors. MATERIALS AND METHODS: Among duodenal epithelial tumors resected endoscopically or surgically in our hospital, we studied the clinicopathological characteristics of 110 adenomas or intramucosal carcinomas...

Intraoperative pyloric procedures are often performed during esophagectomies to reduce the rates of gastric conduit dysfunction. They include pyloroplasty (PP), pyloromyotomy (PM), and pylorus botulinum toxin type-A injections (BI). Despite these procedures, patients frequently warrant further endoscopic interventions. The aim of this study is to compare intraoperative pyloric procedures and the rates of postoperative endoscopic interventions following minimally invasive esophagectomy (MIE). We identified patients who underwent MIE for esophageal carcinoma and grouped them as 'None' (no intervention), 'PP', 'PM', or 'BI' based on intraoperative pyloric procedure type...

BACKGROUND: Infantile hypertrophic pyloric stenosis (IHPS) is the most common surgical cause of nonbilious vomiting in infancy. The etiology of IHPS is not completely understood. Hence, we performed a meta-analysis to investigate the association between perinatal factors and IHPS onset. METHODS: The MEDLINE, EMBASE, PubMed and Cochrane Library databases were searched for studies published in English before December 2016. The combined odd ratios (ORs) and 95% confidence intervals (CIs) were calculated using random-effects models...

The crustacean stomatogastric nervous system is a classic model for understanding the effects of modulating ionic currents and synapses at both the cell and network levels. The stomatogastric ganglion in this system contains two distinct central pattern generators: a slow gastric mill network that generates flexible rhythmic outputs (8-20 s) and is often silent, and a fast pyloric network that generates more consistent rhythmic outputs (0.5-2 s) and is always active in vitro. Different ionic conductances contribute to the properties of individual neurons and therefore to the overall dynamics of the pyloric and gastric mill networks...

We describe a new finding, the "excessive bright echoes" sign, for the diagnosis of hypertrophic pyloric stenosis (HPS). Portal venous gas and gastric wall pneumatosis were noted in 4 vomiting infants proven to have HPS. Portal venous gas can be concerning for ischemic bowel. Gastric wall pneumatosis can be seen in association with necrotizing enterocolitis and has been associated with increased gastric pressure from severe, usually proximal, bowel obstruction. Our HPS cases had prominent bright punctate echoes on sonography of the liver, portal vein lumen, and gastric wall...

Doxycycline induced gastric injury is a rarely recognized side effect of a common medication. Only two cases have previously described the distinctive capillary degeneration identified in gastric mucosa. We expanded on this by describing additional involved sites, endoscopic findings and patient characteristics. Design Gastrointestinal biopsy materials for cases indexed with the word "doxycycline" were retrieved and the histology reviewed. The medical record was used to obtain clinical details. Three cases with biopsy materials were identified from the search and doxycycline ingestion was confirmed...

We report here two cases of gastric adenomas of pyloric type diagnosed during the follow-up of familial adenomatous polyposis (FAP). This rare histological lesion has been only recently described in this particular context and its clinical and pathological spectrum remains to be evaluated. Our two cases were very different in their clinical and endoscopic presentation. In the first patient, the lesion was diagnosed late during the evolution of FAP; it was very large and protruded above the adjacent mucosa; because of its large size, its treatment proved to be difficult...

INTRODUCTION: Oesophagectomy for oesophageal carcinoma carries a high risk of significant morbidity and mortality. Delayed gastric emptying is a relatively common complication following this procedure. A variety of medical, surgical and endoscopic strategies have been described to manage it. The vast majority of cases are related to post-operative pyloric dysfunction and are amenable to conventional management strategies. PATIENTS AND METHODS: We present a new case of a patient with a duodenal hiatus hernia resulting in extrinsic gastroduodenal compression by the massively distended gastric conduit as a cause of gastric outlet obstruction following laparoscopic-assisted Ivor-Lewis oesophagectomy 2 years previously...

BACKGROUND: Pharyngoesophageal stricture (PES) is an Achilles' heel in the management of corrosive injury. Advances in endoscopic techniques were utilized in its management. We classified the stricture as per its dilatability and then planned their treatment. METHODS: PES was sub-categorized based on endoscopic dilatation and availability of cervical oesophagus: group-1 stricture with available cervical oesophagus; group-2 stricture with some part of upper oesophagus made available after endoscopic dilatation and anastomosis in cervico-pharyngeal area; group-3 stricture not amenable for dilatation, anastomosis done at the pharynx...

Central Pattern Generator (CPG) circuits are neural networks that generate rhythmic motor patterns. These circuits are typically built of half-center oscillator subcircuits with reciprocally inhibitory connections. Another common property in many CPGs is the remarkable rich spiking-bursting dynamics of their constituent cells, which balance robustness and flexibility to generate their joint coordinated rhythms. In this paper, we use conductance-based models and realistic connection topologies inspired by the crustacean pyloric CPG to address the study of asymmetry factors shaping CPG bursting rhythms...

A man in his 70s received Helicobacter pylori eradication therapy after endoscopic submucosal dissection (ESD) of the stomach. A small, yellowish, protuberant lesion was later observed on the anterior wall of the lower body of the stomach on surveillance esophagogastroduodenoscopy. Narrow band imaging-magnified endoscopy showed an irregular pit and net-like vascular pattern, with the background mucosa having a light blue crest pattern. A biopsy was performed, which led to a diagnosis of adenoma with a gastric phenotype, so repeat ESD was performed...

A 73-year-old woman underwent upper endoscopic screening that revealed a 30-mm superficial elevated lesion in the anterior wall of the upper gastric body. The lesion had a whitish color and coarse granular surface in conventional white light endoscopy. Magnifying narrow-band imaging indicated irregular microvascular and microsurface patterns within a demarcation line. The microvessels had a distorted polygonal shape within the area surrounded by the marginal crypt epithelium. The patient underwent endoscopic resection...

BACKGROUND: Changing patterns of referral and management of hypertrophic pyloric stenosis (HPS) in North America have recently been described. Comfort with perioperative management, anesthesia, and corrective surgery have been cited as reasons for these changes. Our primary objective was to assess pyloromyotomy outcomes between different hospital types across Canada. The secondary objective was to geospatially map all pyloromyotomies to identify regions of higher HPS incidence across Canada...

Gastric cancer develops from preneoplastic and early neoplastic precursor lesions. In particular, the intestinal type according to the Lauren classification is driven by chronic inflammation and progresses via a chronic gastritis - atrophy/metaplasia - dysplasia - carcinoma sequence. Staging of the extent of atrophy (OLGA) or intestinal metaplasia (OLGIM) enables risk stratification and determines follow-up investigations according to the management of precancerous conditions and lesions in the stomach (MAPS) international guidelines...

Endoscopy plays an important role in the diagnosis and treatment of postoperative complications of gastric cancer. Endoscopic intervention can avoid the second operation and has attracted wide attention. Early gastric anastomotic bleeding after gastrectomy is the most common. With the development of technology, emergency endoscopy and endoscopic hemostasis provide a new treatment approach. According to the specific circumstances, endoscopists can choose metal clamp to stop bleeding, electrocoagulation hemostasis, local injection of epinephrine or sclerotherapy agents, and spraying specific hemostatic agents...
