Reopenable clip over-the-line method in endoscopic full-thickness resection of gastric submucosal tumors: A historical control study.

Objectives: Endoscopic full-thickness resection for gastric submucosal tumors is gradually gaining popularity, and secure and amenable closure is key to its success. This study aimed to compare the reopenable clip over-the-line method with the purse-string method for defect closure after endoscopic full-thickness resection for gastric submucosal tumors.

Methods: This historical control trial included 37 consecutive patients with 37 gastric submucosal tumors, who underwent endoscopic full-thickness resection between January 2021 and July 2024.

Endoscopic mucosal resection and open-lid submucosal biopsy for the diagnosis of diffuse infiltrative gastric cancer: a retrospective observational study.

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.

Impact of preceding treatment for head and neck squamous cell carcinoma on synchronous superficial esophageal squamous cell carcinoma.

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.
