Reasonable decision of anesthesia methods in patients who underwent endoscopic submucosal dissection for superficial esophageal carcinoma: A retrospective analysis in a single Japanese institution.

Background/aims: Despite being a valuable therapeutic option, it has not yet been reported whether endoscopic submucosal dissection (ESD) for superficial esophageal carcinoma should be performed under general or non-general anesthesia (sedation).

Materials And Methods: The clinicopathological factors (age, sex, histology, tumor size, tumor location, tumor macroscopic morphology, and adverse events) of 110 superficial esophageal carcinoma lesions (98 patients) treated by ESD at a single Japanese institution from January 2007 to December 2013 were retrospectively reviewed using medical records.

Results: Among 110 lesions, 94 lesions were resected under general anesthesia, and 16 lesions were resected under non-general anesthesia by an experienced endoscopist.

Clinical Backgrounds and Outcomes of Elderly Japanese Patients with Gastrointestinal Bleeding.

Objective: Elderly gastrointestinal bleeding (GIB) patients sometimes cannot be discharged home. In some cases, they die after hemostasis, even following appropriate treatment. This study investigates the clinical backgrounds and outcomes of elderly Japanese GIB patients.

Usefulness of a traction method using dental floss and a hemoclip for gastric endoscopic submucosal dissection: a propensity score matching analysis (with videos).

Background And Aims: Although endoscopic submucosal dissection (ESD) is a significant advancement in therapeutic endoscopy, it is a complicated technique and requires considerable expertise. In this exploratory study, we evaluated the efficacy of a simple traction method that uses dental floss and a hemoclip (DFC) and was developed to overcome the technical difficulties of ESD.

Methods: In total, 238 early gastric cancers treated by ESD between May 2012 and December 2014 at Tokyo Medical University were retrospectively reviewed.
