Background and study aims: Endoscopic therapy of upper gastrointestinal bleeding remains challenging with conventional endoscopic devices. Use Hemospray, where a nanopowder clotting abilities is sprayed onto the site, had been highly effective for management arterial in heparizined animal model. The safety effectiveness Hemospray hemostasis active peptic ulcer humans was evaluated.

Cholangiocarcinoma (CCA) presents significant diagnostic challenges, resulting in late patient diagnosis and poor survival rates. Primary sclerosing cholangitis (PSC) patients pose a particularly difficult clinical dilemma because they harbor chronic biliary strictures that are to distinguish from CCA. MicroRNAs (miRs) have recently emerged as valuable class of markers; however, thus far, neither extracellular vesicles (EVs) nor miRs within EVs been investigated human bile. We aimed...

Endoscopic therapy of brisk upper gastrointestinal bleeding remains challenging. A proprietary nanopowder (TC-325) has been proven to be effective in high pressure from external wounds. The efficacy and safety TC-325 were assessed a survival animal model.10 animals randomized treatment or sham. All received intravenous antibiotics, H2-blockers heparin (activated clotting time 2 × normal). In sterile laparotomy the gastroepiploic vessels dissected, inserted through 1-cm gastrotomy, freely...

<b>Background and study aims: </b>Fully covered self-expandable metal stents (FCSEMSs) have increasingly been used in benign upper gastrointestinal (UGI) conditions; however, stent migration remains a major limitation. Endoscopic suture fixation (ESF) may prevent migration. The aims of this were to compare the frequency patients who received endoscopic suturing for (ESF group) compared with those did not (NSF assess impact ESF on clinical outcome. <b>Patients methods:</b> This was...

<b>Background and study aims: </b>Endoscopic cryotherapy has been used successfully for the ablation of Barrett’s esophagus but outcome data are limited. The aim this was to assess long-term safety efficacy carbon dioxide (CO<sub>2</sub>) as primary or rescue treatment with high grade dysplasia (HGD) neoplasia. <b>Patients methods:</b> This a retrospective, single-center, nonrandomized carried out in an academic, tertiary care center affiliated community hospital.

The medical literature states that solid radionuclide gastric emptying studies are more sensitive than liquid for detection of gastroparesis and thus rarely indicated. At our institution, patients often referred both studies. Our initial purpose was to review the results in those patients. surprising led us initiate a prospective investigation directly determine relative value versus studies.The retrospective included 21 who had performed on separate days. subsequent initiated so were...

AIM:To determine which patients might benefit most from retrograde viewing during colonoscopy through subset analysis of randomized, controlled trial data. METHODS:The Third Eye ® Retroscope Randomized Clinical Evaluation (TERRACE) was a controlled, multicenter designed to evaluate the efficacy retrograde-viewing auxiliary imaging device that is used provide second video image allows areas on proximal aspect haustral folds and flexures are difficult see with colonoscope's forward view.We...
