The safety and efficacy of endoscopic submucosal fenestration in the treatment of completely embedded upper gastrointestinal foreign body.

Background: Upper gastrointestinal foreign body ingestion is a common digestive tract emergency, of which completely embedded ones were challenging for most endoscopists. We aim to evaluate the efficacy and safety of endoscopic submucosal fenestration in the treatment of completely embedded upper gastrointestinal foreign bodies.

Methods: From December 2018 to December 2021, 19 patients with completely embedded upper gastrointestinal foreign bodies who underwent endoscopic submucosal fenestration in Zhongshan Hospital, Fudan University were included.

Comparison of statins with steroids and botulinum toxin A in the prevention of benign strictures after esophageal endoscopic submucosal dissection: a retrospective cohort study.

Background: Preventing benign strictures following esophageal endoscopic submucosal dissection (ESD) remains difficult, and finding a safe, effective, and simple management method is vital. We previously reported that rosuvastatin significantly reduced the incidence and severity of strictures in a rabbit model of esophageal stricture. Accordingly, in this study, we compared the effects of statins, steroids, and botulinum toxin A (BTX-A) on stricture prevention after ESD involving more than three-fourths of the luminal circumference.
