Therapeutic enteroscopy using a new single-balloon enteroscope: a case series.

Area of Science:

• Gastroenterology
• Endoscopy
• Surgical Innovation

Background:

• Single-balloon enteroscopy (SBE) enables small bowel and biliopancreatic interventions in altered anatomy.
• Conventional SBE has limitations due to a small working channel and lack of a water jet.
• A new prototype, XSIF-180JY, was developed to address these limitations.

Purpose of the Study:

• To evaluate the therapeutic utility of the novel XSIF-180JY single-balloon enteroscope prototype.
• To assess the advantages of its larger working channel and additional water jet feature.

Main Methods:

• Sixteen SBE procedures were performed using the XSIF-180JY prototype over two months.
• Fourteen procedures were therapeutic, including deep enteroscopy and ERCP in patients with Roux-en-Y anatomy.

Main Results:

• The XSIF-180JY facilitated deep enteroscopy with balloon dilation and polypectomies.
• Fourteen ERCP procedures were successfully completed in 12 patients with altered anatomy.
• The 3.2-mm working channel supported sphincterotomy, stone extraction, and stent placement; the water jet aided stone and blood clearance.

Conclusions:

• The XSIF-180JY SBE enables therapeutic enteroscopy and ERCP via its 3.2-mm working channel.
• The integrated water jet effectively cleared biliary stones and blood without obstructing the working channel.
• This advanced SBE prototype enhances therapeutic enteroscopy through its improved design.
