Background And Study Aims: Diffuse infiltrative gastric cancer can be difficult to diagnose owing to a lack of endoscopic features in the superficial mucosa. Moreover, a forceps biopsy may not reveal a pathological diagnosis. We aimed to evaluate the diagnostic yield and safety of endoscopic mucosal resection (EMR) and 'open-lid submucosal biopsy', a technique wherein EMR followed by biopsy of the ulcer floor is performed for a pathological diagnosis.

We aimed to assess the effect of prophylactic clip closure in preventing DB after colorectal ESD among patients on anticoagulants.
Patients And Methods: We used the ABCD-J study database, a large-scale multicenter study analyzing DB among 34,455 colorectal ESD cases from 47 Japanese institutions.
Background: Patients with esophageal squamous cell carcinoma (ESCC) frequently develop synchronous head and neck squamous cell carcinoma (HNSCC). With advances in endoscopic technology and widespread screening of synchronous cancers, the detection of synchronous HNSCC and superficial ESCC (SESCC) is increasing. We aimed to evaluate the impact of preceding HNSCC treatment on synchronous SESCC.

- * Key factors linked to bleeding included the use of antithrombotic agents, the size of the resection wound, and specimen size.
- * Direct oral anticoagulants (DOACs) were significantly associated with higher bleeding rates, indicating a need for caution in patients on these medications during postoperative recovery.
Background And Aims: Local recurrence is a significant concern in endoscopic resection of superficial nonampullary duodenal tumors (SNADTs). Our objective was to elucidate the clinical outcomes of salvage endoscopic treatment.
Methods: This retrospective study included consecutive patients who underwent endoscopic resection of SNADTs between January 2013 and December 2021.
