SUMMARY BackgroundVonoprazan, a potassium-competitive acid blocker, is expected to improve the healing of endoscopic submucosal dissection (ESD)-induced gastric ulcers compared with proton pump inhibitors (PPIs).

Monitoring with BIS during the ESD procedure did not lead to a reduction in the dose of propofol required, but did lead to higher satisfaction scores from the patients and endoscopists. A complicated and prolonged endoscopic treatment such as ESD can be carried out with optimal safety, control, and comfort by using BIS to monitor propofol sedation.

Background and study aims: Preoperative diagnosis of the pathological grade of intraductal papillary mucinous neoplasms (IPMNs) is difficult. This study aimed to evaluate the accuracy of contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS) with time???intensity curve analysis in differentiating between low or intermediate grade dysplasia (LGD/IGD) and high grade dysplasia or invasive carcinoma (HGD/invasive carcinoma) in IPMNs and to assess correlation between the time???intensity curve parameters and tumor microvessel density. Patients and methods: Data from 30 patients with resected IPMNs (14 LGD/IGD, 16 HGD/invasive carcinoma) who underwent CH-EUS with time???intensity curve analysis were evaluated retrospectively. Time???intensity curve parameters and the microvessel density of the mural nodule were compared between the HGD/invasive carcinoma and LGD/IGD groups; the diagnostic accuracy of the time???intensity curve parameters was evaluated. Results: The echo intensity change and echo intensity reduction rate of the mural nodule, and the nodule/pancreatic parenchyma contrast ratio were significantly higher in the HGD/invasive carcinoma group than in the LGD/IGD group (P?

Dilation of choledochojejunal anastomosis combined with stent deployment using DBE-ERCP seems to be a viable first-line treatment for patients with stenosis of choledochojejunal anastomosis.
