A simplified method for stent placement in the distal duodenum: Enteroscopy overtube

Area of Science:

• Gastroenterology
• Interventional Endoscopy

Background:

• Unresectable neoplastic obstruction of the small intestine is often treated with expandable metal stents.
• Endoscopic stent delivery from the distal duodenum presents technical challenges.

Purpose of the Study:

• To demonstrate the utility and technical benefits of using an overtube and single balloon enteroscopy for treating neoplastic stenosis in the small intestine.

Main Methods:

• Case report detailing the use of an overtube and single balloon enteroscopy.
• Focus on endoscopic stent placement in the small intestine.

Main Results:

• The overtube and single balloon enteroscopy approach proved useful.
• This technique offered distinct technical advantages for stent delivery in a challenging location.

Conclusions:

• Overtube-assisted and single balloon enteroscopy are valuable tools for managing complex cases of neoplastic small intestinal obstruction.
• These techniques can facilitate challenging endoscopic stent placements.
