Background and Aims: The application of endoscopic suturing has revolutionized defect closures. Conventional over-the-scope necessitates removal the scope, placement device, reinsertion. A single channel, sequence, through-the-scope device been developed to improve this process. This study aims describe efficacy, feasibility, safety a for gastrointestinal closure. Methods: was retrospective multicenter involving 9 centers consecutive adult patients who underwent using X-Tack Endoscopic HeliX...

<h3>ABSTRACT</h3> There is no national NHS tariff to fund services for patients experiencing long-term bowel and nutritional problems after cancer treatment. In this paper, we report the clinical characteristics outcomes of referred our service estimated cost a completed episode care. Patient characteristics, symptom severity, investigations, diagnoses, number clinic visits referrals elsewhere were recorded in prospective cohort study. During 2013–14, 325 assessment The majority original...

Introduction: Acute cholangitis is a consequence of obstruction and infection the biliary tract. Endoscopic retrograde cholangiopancreatography (ERCP) key in management choice as acute stone extraction and/or stent insertion establishes drainage relief infection. Anatomical variation following Roux-en-Y gastric bypass surgery or patients with esophageal obstructions like our case are prone to make early intervention by ERCP challenge . We describe report septic patient whom gastrostomy tube...

Introduction: Proton pump inhibitors (PPI) and H2-receptor blockers reduce the risk of developing peptic ulcer disease (PUD) in high patients. Patients presenting with non-hematemesis gastrointestinal bleeding (NHGIB) present a diagnostic dilemma for clinicians as may originate from anywhere GI tract. We hypothesize that NHGIB patients concurrently on acid suppressive medications are less likely to have than those not medications, its use upon presentation ED (emergency department) narrow...

Case Report: An 80-year-old male with history of abdominal aortic aneurysm repair 19 years ago presented significant hematochezia, preceded by an episode self-resolving bloody stools two weeks prior. Given his AAA repair, aortoenteric fistula was initially suspected. extensive workup, including angiogram the aorta, 2 successive nuclear RBC scans, EGD to jejunum, and colonoscopies failed visualize a source active bleeding, but did show diffuse colonic diverticulosis. unrelenting bleeding...

Introduction: The association of non-steroidal anti-inflammatory drugs (NSAIDs) with gastrointestinal bleeding (GIB) has been a well-studied correlation. mechanism toxicity clearly defined and is known to result from the inhibition cyclo-oxgenase prostaglandin synthesis, as have risk factors that predispose GIB. We retrospectively studied 336 consecutive patients presenting emergency room GIB separated them based on NSAID use. aim study was improve our understanding how use may changing role...

Video capsule endoscopy (VCE) is a non-invasive diagnostic tool standard in the investigation of obscure gastrointestinal (GI) bleed (OGIB). It postulated that yield may be higher if performed closer to bleeding event. We retrospectively investigated VCEs our medical center analyze patients whose procedure was within 3 days (<3d) admission for overt GI (OOGIB) versus after (>3d) and associated with decreased length stay (LoS) improved therapeutic success.
