Efficacy of traction, using a clip-with-thread, for esophageal endoscopic submucosal dissection for esophageal lesions with fibrosis in an ex vivo pig training model.

Background/aims: Endoscopic submucosal dissection (ESD) of recurrent esophageal carcinoma is technically difficult to perform due to submucosal fibrosis that develops after definitive chemoradiation therapy. Therefore, our aim was to evaluate the usefulness of clip-with-thread traction for ESD of esophageal lesions with submucosal fibrosis.

Materials And Methods: Four endoscopists excised 16 lesions by ESD in an ex vivo pig training model.

Self-Completion Method of Endoscopic Submucosal Dissection Using Endosaber without Any Other Device or Assistance: An ex vivo Porcine Model Study.

Background: Endoscopic submucosal dissection (ESD) is a standard treatment for tumors of the gastrointestinal tract. We developed a self-completion method of ESD using Endosaber to eliminate the need for an additional device or human assistance during the procedure. The aim of this study was to evaluate the technical feasibility and outcomes of this method in an ex vivo porcine training model.

Clutch Cutter knife efficacy in endoscopic submucosal dissection for early gastric neoplasms.

Aim: To compare the outcomes of endoscopic submucosal dissection (ESD) for gastric neoplasms using Clutch Cutter (ESD-C) or other knives (ESD-O).

Methods: This was a single-center retrospective study. Gastric neoplasms treated by ESD between April 2016 and October 2017 at Kitakyushu Municipal Medical Center were reviewed.

Propensity score-matching analysis to compare clinical outcomes of endoscopic submucosal dissection for early gastric cancer in the postoperative and non-operative stomachs.

Background: Endoscopic submucosal dissection (ESD) of the postoperative stomach (ESD-P) for early gastric cancer (EGC) is considered a technically difficult procedure. However, it is difficult to compare the outcomes of ESD-P and ESD of the non-operative stomach (ESD-N) because their baseline characteristics are different. Therefore, we aimed to compare the technical outcomes of ESD-P with those of ESD-N using a propensity score-matching analysis to compensate for the differences.

Early gastric cancer with diffuse heterotopic gastric glands and granular cell tumors mimicking advanced gastric cancer.

Introduction: Heterotopic gastric grands (HGGs) are gastric grands that are observed in the submucosa and are considered to be paracancerous lesions or precursors of gastric cancer (GC). Granular cell tumors (GCTs) are benign neural origin tumors. Gastrointestinal GCTs are rare and gastric GCTs are seldom seen.

Splash M-knife versus Flush Knife BT in the technical outcomes of endoscopic submucosal dissection for early gastric cancer: a propensity score matching analysis.

Background: Endoscopic submucosal dissection (ESD) is a standard treatment for early gastric cancer. A new multi-functional ESD device was developed to achieve complete ESD with a single device. A metal plate attached to its distal sheath achieves better hemostasis during the procedure than the other needle-knife device, Flush Knife BT®, that has been conventionally used.
