Abstract

Background: Although endoscopic submucosal dissection (ESD) provides a high rate of curative resection, the remaining gastric mucosa after ESD is at risk for metachronous superficial gastric epithelial neoplasms (MSGENs). It leaves room for risk factors for developing MSGENs after ESD. This study aimed to identify clinicopathological risk factors for the occurrence of MSGENs, and to evaluate the association of Helicobacter pylori (H. pylori) with the MSGENs. Methods: We conducted a retrospective cohort study including 369 patients with 382 lesions that underwent ESD for adenoma/early gastric cancer. Results: Twenty-seven MSGENs occurred. The subjects were divided into MSGEN and not-MSGEN groups. There was a significantly higher frequency of histological intestinal metaplasia (HIM) and initial neoplasm location in the upper or middle parts (INUM) in the MSGEN group. The HIM and INUM groups had a significantly higher cumulative incidence of MSGENs. We compared 27 patients from the MSGEN group and 27 patients from the not-MSGEN group that were matched to the MSGEN group for variables including HIM and INUM. There was a significantly higher frequency of the spontaneous disappearance of H. pylori in the MSGEN group. Conclusions: HIM, INUM, and the spontaneous disappearance of H. pylori may be clinicopathological risk factors for developing MSGENs after ESD. [ABSTRACT FROM AUTHOR]

Subjects
*GASTRIC varices, *ENDOSCOPIC ultrasonography, *PORTAL hypertension, *OPERATIVE ultrasonography, *GASTROINTESTINAL hemorrhage, *PORTAL vein
Abstract

With the recent development of interventional endoscopic ultrasound (EUS), EUS‐guided vascular interventions have seen increased clinical and research focus. This modality can be used to diagnose portal hypertension and treat portal hypertension‐related gastrointestinal varices and refractory gastrointestinal hemorrhage, including pseudoaneurysm. The vascular embolic materials used for treatment include tissue adhesives (cyanoacrylates), sclerosants, thrombin, and vascular embolic coils, all of which are associated with favorable results. The feasibility of EUS‐guided procedures, including portal vein stenting and portosystemic shunt formation conventionally performed percutaneously and transvenously, has also been demonstrated, albeit in animal studies. As EUS‐guided vascular intervention is a technique that may receive significant attention in the future, we provide a thorough review of the current evidence for its use. [ABSTRACT FROM AUTHOR]

Abstract

A new type of sphincterotome released to the market recently has high rotation performance and a freely bendable blade. It is devised to be singly capable of accommodating not only normal anatomy but also cases with surgically altered anatomy. This study was undertaken for clinical evaluation of the usefulness of this new sphincterotome. Eight cases in a reconstructed intestine for which cannulation or endoscopic sphincterotomy (EST) had been performed were extracted from 32 cases for which endoscopic retrograde cholangiopancreatography-related procedures were performed using the sphincterotome developed during November 2023 through February 2024. The cases were investigated retrospectively. Among these, EST was applied to six cases. Cannulation was performed using the developed sphincterotome in the native papilla in four cases. The primary endpoints were the success rate of cannulation in surgically altered anatomy and the success rate of EST. Secondary endpoints were complications and usability for operators. Usability for operators was evaluated by questionnaire for several items on a 5-point scale. EST was conducted successfully in all six cases subjected to EST. Mild hemorrhage was observed in one case (17%) as an adverse event after EST. Deep cannulation to the native papilla with the developed sphincterotome was conducted successfully in three cases (75.0%). Evaluation results by operators were 4.4 ± 0.55 for rotation performance, 4.00 ± 0.63 for incision performance, 4.29 ± 0.49 for deep cannulation performance, and 4.07 ± 0.19 for overall evaluation. In conclusion, this developed sphincterotome might be very useful for EST and cannulation in cases with surgically altered anatomy., Competing Interests: None., (© 2024 The Author(s).

Abstract

Endoscopic ultrasound (EUS)-guided coil deployment (EUS-coiling) has been newly developed for treating isolated gastric varices (iGV). This report describes three cases of EUS-coiling for iGV using a 0.035-inch hydrocoil (Azur; Terumo Corp., Tokyo, Japan). When used for EUS-coiling, this hydrocoil provides the following benefits: Its electrically detachable system allows pull back. It has smooth and dense deployment. Moreover, it has a strong blood-flow blocking effect because of its long length and large diameter with internal swelling functions of the hydrogel. Technical success of coiling was achieved in all cases. After coiling, additional treatments such as cyanoacrylate and sclerosant injection were performed as deemed appropriate. All iGVs were obliterated successfully. No adverse event occurred during the procedure or during the mean follow-up of six months. Our findings indicate that this 0.035-inch hydrocoil can be used to treat iGV safely and effectively., Competing Interests: Rafael Romero‐Castro has been a consultant to Cook Medical since February 28, 2023., (© 2023 The Authors.
