Endoscopic devices and techniques for the management of gastric varices (with videos).

Background And Aims: Gastric variceal bleeding occurs less commonly than bleeding from esophageal varices (EVs), although it is associated with higher morbidity and mortality. Bleeding from gastroesophageal varices type 1 (GOV1) is treated like EVs. In contrast, other forms of gastric variceal bleeding, including gastroesophageal varices type 2 (GOV2) and isolated gastric varices types 1 (IGV1) and 2 (IGV2), are treated with varying endoscopic approaches.

Submucosal injection fluid and tattoo agents.

Background And Aims: EMR and endoscopic submucosal dissection (ESD) are minimally invasive endoscopic techniques, developed for the removal of benign and early malignant lesions throughout the GI tract. Submucosal injection of a marking agent can help to identify lesions during surgery. Endoscopic resection frequently involves "lifting" of the lesions by injection of a substance within the submucosal space to create a cushion for safe resection.

North American Expert Consensus on the Post-procedural Care of Patients After Per-oral Endoscopic Myotomy Using a Delphi Process.

Background & Aims: There is significant variability in the immediate post-operative and long-term management of patients undergoing per-oral endoscopic myotomy (POEM), largely stemming from the lack of high-quality evidence. We aimed to establish a consensus on several important questions on the after care of post-POEM patients through a modified Delphi process.

Methods: A steering committee developed an initial questionnaire consisting of 5 domains (33 statements): post-POEM admission/discharge, indication for immediate post-POEM esophagram, peri-procedural medications and diet resumption, clinic follow-up recommendations, and post-POEM reflux surveillance and management.

Identifying risk factors for anal cancer in people with HIV in Spain: a multicentre retrospective cohort study nested in the PISCIS cohort.

Background: People with HIV have a substantially higher risk of anal cancer than the general population. We aimed to identify risk factors associated with the development of anal cancer among people with HIV to implement more effective and targeted screening strategies.

Methods: We conducted a multicentre retrospective cohort study in 16 hospitals across Catalonia and the Balearic Islands, Spain, between Jan 1, 1998, and Dec 31, 2022.
