Intestinal failure (IF) is a condition characterized by the inability to maintain a state of adequate nutrition, or fluid and electrolyte balance due to an anatomical or a physiological disorder of the gastrointestinal system. IF can be an extremely debilitating condition, significantly affecting the quality of life of those affected. The surgical management of patients with acute and chronic IF requires a specialist team who has the expertise in terms of technical challenges and decision-making. Read More

Purpose: A significant feature of pediatric inflammatory bowel diseases (IBD), which include Crohn disease (CD), and ulcerative colitis (UC), is failure to suppress inflammation. The inability to regulate inflammation renders a major challenge toward establishing effective treatments in IBD. Nuclear factor kappa-light-chain-enhancer of activated B-cells-induced inflammation is inhibited by A20 through interactions with TAX1BP1 (Tax1-binding protein 1) and A20-binding inhibitor of NF-κβ activation (ABIN)-1 (A20 binding and inhibitor of NF-κβ) and upon phosphorylation by inhibitor of nuclear factor kappa-β kinase subunit beta (IKKβ), which stabilizes it.

Increased blood ammonia (NH) is an important causative factor in hepatic encephalopathy, and clinical treatment of hepatic encephalopathy is focused on lowering NH. Ammonia is a central element in intraorgan nitrogen (N) transport, and modeling the factors that determine blood-NH concentration is complicated by the need to account for a variety of reactions carried out in multiple organs. This review presents a detailed quantitative analysis of the major factors determining blood-NH homeostasis - the N metabolism of urea, NH, and amino acids by the liver, gastrointestinal system, muscle, kidney, and brain - with the ultimate goal of creating a model that allows for prediction of blood-NH concentration.

Background And Aims: Initial clinical management decision in patients with acute gastrointestinal bleeding (GIB) is often based on identifying high- and low-risk patients. Little is known about the role of lactate measurement in the triage of patients with acute GIB. We intended to assess if lactate on presentation is predictive of need for intervention in patients with acute GIB. Read More

Introduction: The Internet has become an increasingly popular resource for medical information. Fecal microbiota transplantation (FMT) has changed the treatment of with cure rates of 81% following one infusion of FMT, further studies have since validated these findings. The Medicines and Health care Products Regulatory Agency has classified FMT as a medicine and hence should be only utilized in strict clinical settings. Read More

Background: While gastrointestinal (GI) effects of standard ibuprofen and N-acetyl-p-aminophenol (APAP) have been reported, upper GI injury following treatment with fast-dissolving (FD) formulations of these analgesics has not been investigated. We evaluated upper GI effects of over-the-counter doses of 2 FD ibuprofen products and 1 FD-APAP product.
Methods: In a randomized, placebo-controlled, endoscopist-blinded, 4-way crossover study, 28 healthy subjects received FD ibuprofen 2×200 mg liquid capsules 3 times daily (TID), ibuprofen 2×200 mg tablets TID, FD-APAP 2×500 mg tablets 4 times daily (QID), and placebo 2×500 mg tablets QID for 7 days.

Purpose: Variations in the caliber of human large intestinal tract causes changes in pressure and the velocity of its contents, depending on flow volume, gravity, and density, which are all variables of Bernoulli's principle. Therefore, it was hypothesized that constipation and diarrhea can occur due to changes in the colonic transit time (CTT), according to Bernoulli's principle. In addition, it was hypothesized that high amplitude peristaltic contractions (HAPC), which are considered to be involved in defecation in healthy subjects, occur because of cecum pressure based on Bernoulli's principle.

A significant percentage of patients with gastroesophageal reflux disease (GERD) will not respond to proton pump inhibitor (PPI) therapy. The causes of PPI-refractory GERD are numerous and diverse, and include adherence, persistent acid, functional disorders, nonacid reflux, and PPI bioavailability. The evaluation should start with a symptom assessment and may progress to imaging, endoscopy, and monitoring of esophageal pH, impedance, and bilirubin. Read More

Background/aims: As increasing numbers of Crohn's disease (CD) cases are being recognized in India, so the differential diagnosis of CD and gastrointestinal tuberculosis (GITB) is becoming increasingly important. If patients are misdiagnosed with GITB, toxicity may result from unnecessary anti-TB therapy and treatment of the primary disease (ie, CD) gets delayed. We therefore aimed to assess the accuracy of various parameters that can be used to predict GITB diagnosis at index evaluation. Read More

Erosive esophagitis (EE) occurs when the epithelial mucosa is damaged due to gastric acid reflux, and the incidence of this disease is increasing in Japan due to changes in diet and lifestyle. The condition can be treated using proton pump inhibitors (PPIs) that act by irreversibly blocking the H,K-ATPase responsible for acid secretion. Vonoprazan is a K competitive channel inhibitor, which reversibly and potently inhibits gastric acid secretion. Read More

The limited efficacy of the currently available medical therapies in a proportion of patients with Crohn's disease has led to the research and development of molecules that can block new inflammatory pathways. Ustekinumab is a fully human IgG1 monoclonal antibody which targets the common p40 subunit of the cytokines interleukin-12 as well as interleukin-23. Consequently, the Th1 and Th17 inflammatory responses are inhibited. Read More

Endoscopic submucosal dissection (ESD) enables en bloc resection of large complex colorectal superficial neoplastic lesions, resulting in very low rates of local recurrence, high-quality pathologic specimens for accurate histopathologic diagnosis and potentially curative treatment of early adenocarcinoma without resorting to major surgical resection. The safety and efficacy of the technique, which was pioneered in the upper gastrointestinal tract, has been established by the consistently impressive outcomes from expert centers in Japan and some other eastern countries. However, ESD is challenging to perform in the colorectum and there is a significant risk of complications, particularly in the early stages of the learning curve. Read More

Gastric antral vascular ectasia (GAVE), also known as "watermelon stomach", is an uncommon condition, which can cause gastrointestinal bleeding due to rupture of blood vessels that line the stomach. The pathogenesis of GAVE remains unclear; however it is thought that hemodynamic changes, mechanical stress, and autoimmune factors all have a part to play. A range of conditions are also commonly associated with the syndrome, such as portal hypertensive gastropathy, liver cirrhosis, and autoimmune disorders. Read More

Secondary sclerosing cholangitis (SSC) is a term used for a group of chronic cholestatic disease affecting the intra- and/or extrahepatic biliary tree with inflammation and progressive stricture formation, which can lead to biliary cirrhosis. A newly recognized form of SSC is secondary sclerosing cholangitis in critically ill patients (SSC-CIP). Pathogenesis is believed to involve ischemic injury of intrahepatic bile ducts associated with prolonged hypotension, vasopressors administration, and/or mechanical ventilation in patients treated in the intensive care unit (ICU).

Ulcerative colitis (UC) is a chronic relapsing and remitting inflammatory bowel disease, with a characteristic leukocytic infiltration of the mucosa. Immunosuppression including anti-TNF-α therapy is a mainstay of treatment for many; however, systemic immunosuppression is not universally effective and is associated with potential side effects. The gut-tropic integrin α4β7, which is expressed on leukocytes, mediates migration from the circulation to the intestinal mucosa. Read More
