New insertion method of transnasal ileus tube for small bowel obstruction: Anterior balloon method.

Background: Small bowel obstruction (SBO) is usually caused by postoperative adhesions and malignant disease, and decompression is effective for SBO. Our previous case report suggested that a new transnasal ileus tube insertion method, the anterior balloon method (ABM), could achieve decompression for adhesive SBO.

Aims: The study aimed to investigate the effectiveness of a new method for inserting transnasal ileus tubes in patients with SBO.

Comparison of sedation between the endoscopy room and operation room during endoscopic submucosal dissection for neoplasms in the upper gastrointestinal tract.

Background: The present study was performed to compare the safety of sedation during endoscopic submucosal dissection (ESD) in the endoscopy room versus operation room.

Methods: In total, 297 patients with gastrointestinal tumors who underwent ESD from January 2011 to December 2016 were retrospectively reviewed. The patients were divided into two groups: those who underwent ESD in the endoscopy room without propofol (Group E) versus operation room with propofol (Group O).
