BACKGROUND AND AIMS: The Rome IV criteria define functional gastrointestinal (GI) disorders by specific combinations of symptoms. It is possible to empirically evaluate these symptom combinations by factor analysis (a statistical procedure that groups variables that correlate). However, this analysis has not been performed for the Rome IV criteria, and factor analyses based on the previous versions of the Rome criteria did not use population-based data. We therefore investigated symptom grouping by the Rome IV questionnaire using factor analysis of a population-based sample...

GERD has become one of the most frequent pathology of the upper GI tract. It is a spectrum disease and is a progressive disease as well. Serious and severe complications are possible. The mainstream therapy in most of the patients is the medical therapy with PPI's. The most severe cases with an impaired LES (Lower Esophageal Sphincter) function as well as important anatomical disruptions are of surgical indication, the gold standard being laparoscopic fundoplication, an elective therapy with long term follow up outcomes at the expense of de novo symptoms associated with fundoplications in general...

Objectives: A diagnostic need often arises to estimate bone age from X-ray images of the hand of a subject during the growth period. Together with measured physical height, such information may be used as indicators for the height growth prognosis of the subject. We present a way to apply the deep learning technique to medical image analysis using hand bone age estimation as an example. Methods: Age estimation was formulated as a regression problem with hand X-ray images as input and estimated age as output...

BACKGROUND AND AIM: The management of subepithelial tumors with a predominant extraluminal growth pattern or extra-gastrointestinal (GI) tumors can be challenging and traditionally requires a surgical resection that is not only invasive but may carry a significant risk of morbidity and mortality. We aim to assess the feasibility, safety and efficacy of a novel endoscopic technique termed as submucosal tunnel endoscopic resection for Extraluminal Tumors (STER-ET). METHODS: We prospectively enrolled patients who underwent STER-ET for gastrointestinal subepithelial tumors with a predominant extraluminal growth pattern or extra-GI tumors located at the level of cardia or the proximal part of the lesser curvature of the stomach seen on cross-sectional imaging between January 2016 and March 2017...

Background: Bleeding complications especially gastrointestinal bleeding remains a major challenge associated with oral anticoagulation therapy (OAT) and often leads clinicians to withdraw oral anticoagulation therapy (OAT) . This exposes patients to risk of stroke and systemic thromboembolism (STE). Novel oral anticoagulants (NOACs) have proved no better when it comes to bleeding events and in fact studies have shown that overall NOACs are associated with higher incidence of gastrointestinal (GI) bleeding compared to warfarin ...

BACKGROUND: The radiological evaluation of the upper gastrointestinal tract (GI tract) is a diagnostic challenge. Although endoscopy has pushed radiographic methods into the background, these methods continue to play a key role in the diagnosis of dysphagia. In addition, cross-sectional imaging (computed tomography, magnetic resonance imaging) is increasingly used in complex clinical cases to evaluate surrounding tissue changes. METHODS: By combining conventional double-contrast techniques with a video recording, the entire upper GI tract can be assessed both anatomically and functionally in one examination procedure...

Barolith is a mixture of firm feces with barium sulfate, and a frequent cause of obstruction of the appendiceal lumen that can result in appendicitis. Nonetheless, some other complications like aspiration, allergic reaction, and bowel obstruction have also been reported.  We present the case of a 71-year-old man with a history of amyotrophic lateral sclerosis (ALS), who came to the gastroenterology clinic complaining of intermittent loose stools and dysphagia to solids for the past months. The patient underwent a barium swallow study six days prior and was completely normal...

Hepatic portal venous gas (HPVG) is caused by gastrointestinal (GI) mucosal damage alone or in combination with bowel distension, sepsis, and invasion by gas-producing bacteria. The most common cause is mesenteric ischemia associated with bowel necrosis. Iatrogenic HPVG is a rare condition that occurs following various endoscopic procedures 1 . Herein, we present an unusual case of HPVG following balloon endoscopy (BE). This article is protected by copyright. All rights reserved.

BACKGROUND: Patients with heterotaxy syndrome (HS) often have asymptomatic malrotation. There is a lack of consensus regarding the management of these patients, particularly in patients with complex congenital heart disease (CHD). We sought to describe the prevalence of malrotation and incidence of volvulus in a population of patients with complex CHD and to identify the impact of malrotation on morbidity and mortality following cardiac surgery. METHODS: We performed a retrospective review of all patients with HS and complex CHD who required cardiac surgery in the first year of life at a single center between October 1995 and September 2015...

Enhancement of antibody-dependent cellular cytotoxicity (ADCC) with some modalities may be a promising approach to enhance the efficacy of therapeutic monoclonal antibodies (mAbs). It has previously been demonstrated that the removal of fucose from antibody oligosaccharides (defucosylation) leads to augmentation of ADCC activity. To establish clinically relevant evidence of this procedure, the present study evaluated trastuzumab- and cetuximab-mediated ADCC by comparing defucosylated mAbs with conventional mAbs using peripheral blood mononuclear cells (PBMCs)...
