Hemospray® (hemostatic powder TC-325) as monotherapy for acute gastrointestinal bleeding: a multicenter prospective study.

Background: Hemostatic powders are used as second-line treatment in acute gastrointestinal (GI) bleeding (AGIB). Increasing evidence supports the use of TC-325 as monotherapy in specific scenarios. This prospective, multicenter study evaluated the performance of TC-325 as monotherapy for AGIB.

Retrospective comparison of G-EYE balloon-colonoscopy with standard colonoscopy for increased adenoma detection rate and reduced polyp removal time.

The newly introduced G-EYE colonoscope (G-EYE) employs a balloon, installed at the bending section of a standard colonoscope (SC), for increasing adenoma detection and stabilizing the colonoscope tip during intervention. This retrospective work explores the effect of introducing G-EYE into an SC endoscopy room, in terms of adenoma detection and polyp removal time. This was a single-center, retrospective study.

Unmasking lower gastrointestinal bleeding under administration of norepinephrine.

Background: Bleeding in the gastrointestinal tract is common and transarterial embolization enables the clinician to control gastrointestinal bleeding. Contrast extravasation is a prerequisite for successful embolization. Provocative angiography is helpful in the detection of elusive bleeding.

[Parkinson's disease].

Parkinson's disease (PD) is an unparalleled example of a neurodegenerative disorder that can be effectively managed leading to sustained symptom control and quality of life. The cooperation of neurologists with general practitioners, gastroenterologists, and geriatricians is of increasing importance for an optimized management of PD. New diagnostic criteria for PD and for atypical Parkinsonism, which should be considered in the differential diagnostics, include non-motor symptoms and aim to diagnose these disorders as early as possible.

Endoscopic hemostasis makes the difference: Angiographic treatment in patients with lower gastrointestinal bleeding.

Background: The large majority of gastrointestinal bleedings subside on their own or after endoscopic treatment. However, a small number of these may pose a challenge in terms of therapy because the patients develop hemodynamic instability, and endoscopy does not achieve adequate hemostasis. Interventional radiology supplemented with catheter angiography (CA) and transarterial embolization have gained importance in recent times.

Hemostatic powder TC-325 treatment of malignancy-related upper gastrointestinal bleeds: International registry outcomes.

Background And Aim: Upper gastrointestinal tumors account for 5% of upper gastrointestinal bleeds. These patients are challenging to treat due to the diffuse nature of the neoplastic bleeding lesions, high rebleeding rates, and significant transfusion requirements. TC-325 (Cook Medical, North Carolina, USA) is a hemostatic powder for gastrointestinal bleeding.

Outcomes of Hemospray therapy in the treatment of intraprocedural upper gastrointestinal bleeding post-endoscopic therapy.

Introduction: With increasing advances in minimally invasive endoscopic therapies and endoscopic resection techniques for luminal disease, there is an increased risk of post-procedure bleeding. This can contribute to significant burden on patient's quality of life and health resources when reintervention is required. Hemospray (Cook Medical, North Carolina, USA) is a novel haemostatic powder licensed for gastrointestinal bleeding.

Hemostatic spray powder TC-325 in the primary endoscopic treatment of peptic ulcer-related bleeding: multicenter international registry.

Background: Upper gastrointestinal bleeding (UGIB) is a leading cause of morbidity and is associated with a 2 % - 17 % mortality rate in the UK and USA. Bleeding peptic ulcers account for 50 % of UGIB cases. Endoscopic intervention in a timely manner can improve outcomes.

Outcomes from an international multicenter registry of patients with acute gastrointestinal bleeding undergoing endoscopic treatment with Hemospray.

Background And Aim: Acute gastrointestinal bleeding carries poor outcomes unless prompt endoscopic hemostasis is achieved. Mortality in these patients remains significant. Hemospray is a novel intervention that creates a mechanical barrier over bleeding sites.

Terlipressin and albumin combination treatment in patients with hepatorenal syndrome type 2.

Background: Hepatorenal syndrome (HRS) is associated with a poor prognosis. In HRS type 1, loss of renal function is rapidly progressive, while HRS type 2 is characterised by chronic ascites and more moderately elevated renal parameters. While treatment with terlipressin/albumin is well established in type 1, its effectiveness in chronic HRS is less clear.

G-EYE colonoscopy is superior to standard colonoscopy for increasing adenoma detection rate: an international randomized controlled trial (with videos).

Background And Aims: Colorectal cancer (CRC) is largely preventable with routine screening and surveillance colonoscopy; however, interval cancers arising from precancerous lesions missed by standard colonoscopy still occur. An increased adenoma detection rate (ADR) has been found to be inversely associated with interval cancers. The G-EYE device includes a reusable balloon integrated at the distal tip of a standard colonoscope, which flattens haustral folds, centralizes the colonoscope's optics, and reduces bowel slippage.

Endoscopic and angiographic management of lower gastrointestinal bleeding: Review of the published literature.

Lower gastrointestinal bleeding is common and occurs often in elderly patients. In rare cases it is associated with hemorrhagic shock. A large number of such bleedings, which are often caused by colon diverticula, subside spontaneously.

G-EYE advanced colonoscopy for improved polyp detection rates - a randomized tandem pilot study with different endoscopists.

Background And Aims:  The most commonly missed polyps in colonoscopy are those located behind haustral folds. The G-EYE system is a standard colonoscope consisting of re-processable balloon at its distal tip. The G-EYE balloon improves the detection of polyps by straightening the haustral folds.

The Manchester Triage System (MTS): a score for emergency management of patients with acute gastrointestinal bleeding.

Background:  Suspected gastrointestinal (GI) bleeding is a common initial diagnosis in emergency departments. Despite existing endoscopic scores to estimate the risk of GI bleeding, the primary clinical assessment of urgency can remain challenging. The 5-step Manchester Triage System (MTS) is a validated score that is often applied for the initial assessment of patients presenting in emergency departments.

A guide to multimodal endoscopy imaging for gastrointestinal malignancy - an early indicator.

Multimodality imaging is an essential aspect of endoscopic surveillance for the detection of neoplastic lesions, such as dysplasia or intramucosal cancer, because it improves the efficacy of endoscopic surveillance and therapeutic procedures in the gastrointestinal tract. This approach reveals mucosal abnormalities that cannot be detected by standard endoscopy. Currently, these imaging techniques are divided into those for primary detection and those for targeted imaging and characterization, the latter being used to visualize areas of interest in detail and permit histological evaluation.

[Rare gastroenterologic finding as a cause of hypochromic microcytic anemia].

Case History: A 66-year-old woman suffering from skin paleness and weakness presented an increasing hypochromic, microcytic anemia. Diagnostic: In an ambulant setting a capsule endoscopy of the small intestine was carried out because of multiple polyps of the colon (colonoscopy) in addition to non-invasive (Hämoccult-Test) and invasive (gastroscopy) diagnostic. The patient was then admitted to hospital to clarify a suspicious ulcer of the small bowl.

Intraprocedural bowel cleansing with the JetPrep cleansing system improves adenoma detection.

Aim: To investigate the impact of JetPrep cleansing on adenoma detection rates.

Methods: In this prospective, randomized, crossover trial, patients were blindly randomized to an intervention arm or a control arm. In accordance with the risk profile for the development of colorectal carcinoma, the study participants were divided into high-risk and low-risk groups.

Acute gastrointestinal bleeding - a new approach to clinical and endoscopic management.

Overt or occult gastrointestinal bleeding is a frequently observed condition in routine gastroenterological practice. Occult gastrointestinal bleeding is usually a purely incidental finding, based on the discovery of iron deficiency anemia in the laboratory or blood in stool (a positive Hemoccult test). However, overt bleeding accompanied by the clinical features of tarry stool, hematemesis, or hematochezia may be a life-threatening condition, calling for immediate emergency management.

[Response to Terlipressin and albumin is associated with improved outcome in patients with cirrhosis and hepatorenal syndrome].

Background And Aim: Hepatorenal syndrome (HRS) is a severe but potentially reversible complication in patients with cirrhosis. Untreated it is associated with a poor prognosis. Several randomized controlled trials (RCT) demonstrated that treatment with terlipressin and albumin improves renal function.

Proteins of the VEGFR and EGFR pathway as predictive markers for adjuvant treatment in patients with stage II/III colorectal cancer: results of the FOGT-4 trial.

Background: Unlike metastatic colorectal cancer (CRC) there are to date few reports concerning the predictive value of molecular biomarkers on the clinical outcome in stage II/III CRC patients receiving adjuvant chemotherapy. Aim of this study was to assess the predictive value of proteins related with the EGFR- and VEGFR- signalling cascades in these patients.

Methods: The patients' data examined in this study were from the collective of the 5-FU/FA versus 5-FU/FA/irinotecan phase III FOGT-4 trial.

High definition plus colonoscopy combined with i-scan tone enhancement vs. high definition colonoscopy for colorectal neoplasia: A randomized trial.

Background: High definition endoscopy is the accepted standard in colonoscopy. However, an important problem is missed polyps.

Aims: Our objective was to assess the additional adenoma detection rate between high definition colonoscopy with tone enhancement (digital chromoendoscopy) vs.

New aspects of modern endoscopy.

The prognosis for patients with malignancies of the gastrointestinal-tract is strictly dependent on early detection of premalignant and malignant lesions. However, small, flat or depressed neoplastic lesions remain difficult to detect with these technologies thereby limiting their value for polyp and cancer screening. At the same time computer and chip technologies have undergone major technological changes which have greatly improved endoscopic diagnostic investigation.

To biopsy or not to biopsy: evaluation of a large German cohort of patients with abnormal liver tests of unknown etiology.

Background And Aims: Despite increasingly sensitive and accurate blood tests to detect liver disease, liver biopsy remains very useful in patients with atypical clinical features and abnormal liver tests of unknown etiology. The aim was to determine those elevated laboratory liver parameters that cause the clinician to order a biopsy, and whether laboratory tests are associated with pathological findings on histology.

Methods: 504 patients with unclear hepatopathy, admitted to the outpatient clinic of a university hospital between 2007 and 2010, were analyzed with respect to laboratory results, clinical data, and the results of liver biopsies.

Beyond standard image-enhanced endoscopy confocal endomicroscopy.

Endomicroscopy is a new imaging tool for gastrointestinal endoscopy. In vivo histology becomes possible at subcellular resolution during ongoing colonoscopy. Panchromoendoscopy with targeted biopsies has become the method of choice for surveillance of patients with inflammatory bowel disease.

Efficacy of SpyGlass(TM)-directed biopsy compared to brush cytology in obtaining adequate tissue for diagnosis in patients with biliary strictures.

Aim: To evaluate the diagnostic yield (inflammatory activity) and efficiency (size of the biopsy specimen) of SpyGlass(TM)-guided biopsy vs standard brush cytology in patients with and without primary sclerosing cholangitis (PSC).

Methods: At the University Medical Center Mainz, Germany, 35 consecutive patients with unclear biliary lesions (16 patients) or long-standing PSC (19 patients) were screened for the study. All patients underwent a physical examination, lab analyses, and abdominal ultrasound.
