Comparison of Hemospray and Endoclot for the treatment of gastrointestinal bleeding.

Background: Gastrointestinal (GI) bleeding is a common indication for endoscopy. For refractory cases, hemostatic powders (HP) represent "touch-free" agents.

Aim: To analyze short term (ST-within 72 h-) and long-term (LT-within 30 d-) success for achieving hemostasis with HP and to directly compare the two agents Hemospray (HS) and Endoclot (EC).

Endoscopic full-thickness resection with an over-the-scope clip device (FTRD) in the colorectum: results from a university tertiary referral center.

Background And Study Aims:  The full-thickness resection device (FTRD) represents a novel endoscopic treatment method for lesions unresectable with conventional endoscopic techniques. The overall aim of this study was to evaluate technical success and in toto resection rates, recurrence rates, as well as immediate or late complications in patients who underwent polyp removal with the FTRD.

Patients And Methods:  Data from a prospectively collected database of 12 patients who underwent 13 over-the-scope clip-based full-thickness resections between June 2015 and June 2017 were analyzed.

Excretion of urinary histamine and N-tele methylhistamine in patients with gastrointestinal food allergy compared to non-allergic controls during an unrestricted diet and a hypoallergenic diet.

Background: Patients with gastrointestinal food allergy are characterised by increased production of mast cell derived mediators upon allergen contact and present often with unspecific symptoms. The aim of this study was to evaluate urinary histamine and methylhistamine excretion in patients with food allergy and to compare their values with food-tolerant controls.

Methods: In a retrospective case control study the urinary excretion parameters were analysed from 56 patients (40.

Perforation during esophageal dilatation: a 10-year experience.

Background & Aim: Esophageal stenosis can be caused by malignant, postsurgical, benign diseases etc. Endoscopic treatment options consist primarily of balloon dilatation and bougination. Both interventions carry a certain risk of further complications such as perforations.

Over-the-scope clip application yields a high rate of closure in gastrointestinal perforations and may reduce emergency surgery.

Background: Perforation of the gastrointestinal tract may cause various complications and may require emergency surgery, even in patients with significant comorbidities.

Methods: Seventeen consecutive patients with indication for surgery due to a visible gastrointestinal perforation were treated with OTSC application. In this study, cause of perforation, estimated size, location, rate of perforation closure, outcome and complications were reported.

Strategies for training in diagnostic upper endoscopy: a prospective, randomized trial.

Background: Training simulators have been used for decades with success; however, a standardized educational strategy for diagnostic EGD is still lacking.

Objective: Development of a training strategy for diagnostic upper endoscopy.

Study Design: Prospective, randomized trial.

Hemodynamic efficacy of the over-the-scope clip in an established porcine cadaveric model for spurting bleeding.

Background: Clip application has been proven to be effective for endoscopic hemostasis. There are limited bench data on the efficacy of the over-the-scope clip (OTSC) for the treatment of spurting GI hemorrhage. We evaluated the hemodynamic efficacy of the OTSC in an established bleeding model.

Refinement of ERCP by using the Olympus V-scope system with a 0.025 in. compatible and complete fixable Visiglide(®) guidewire.

Aim: Prospective evaluation of the new 0.025 in. Visiglide(®) guidewire to facilitate endoscopic retrograde cholangiopancreaticography using the Olympus V-scope.

Double-balloon-enteroscopy-based endoscopic retrograde cholangiopancreatography in post-surgical patients.

Aim: To evaluate double balloon enteroscopy (DBE) in post-surgical patients to perform endoscopic retrograde cholangiopancreatography (ERCP) and interventions.

Methods: In 37 post-surgical patients, a stepwise approach was performed to reach normal papilla or enteral anastomoses of the biliary tract/pancreas. When conventional endoscopy failed, DBE-based ERCP was performed and standard parameters for DBE, ERCP and interventions were recorded.

Experiences with a long-term treatment of a massive gluteal acne inversa with infliximab in Crohn's disease.

Background: In 40% of all cases of Crohn's disease fistulas emerge during the course of disease. Nevertheless, acne inversa has to be taken into account as an infrequent differential diagnosis. Infliximab as an antibody against the pro-inflammatory mediator TNF-alpha is active in cases of acute Crohn's disease, concomitant fistulas and cutaneous manifestations.
