Direct-vision stenting: the way forward for malignant oesophageal obstruction

Area of Science:

• Gastroenterology
• Interventional Endoscopy
• Oncology

Background:

• Self-expanding metallic stents are standard for esophageal cancer dysphagia palliation.
• Current stent insertion relies on fluoroscopic guidance, which can be inaccurate and time-consuming.
• Limited fluoroscopy access can hinder treatment in some centers.

Purpose of the Study:

• To assess the efficacy and safety of direct-vision stent insertion without fluoroscopy.
• To evaluate this technique as an alternative for esophageal cancer palliation.

Main Methods:

• Prospective study of 50 consecutive patients with inoperable esophageal cancer.
• Utilized 7-cm or 11-cm covered Choo stents.
• Stent insertion performed under direct vision.

Main Results:

• 52 stents were successfully inserted under direct vision.
• Procedures averaged under 15 minutes with good palliation and no complications.
• Fluoroscopic assistance was needed in only one case.

Conclusions:

• Direct-vision stent insertion is a simple, safe, and effective method.
• This technique rarely requires fluoroscopic assistance.
• It is particularly beneficial for centers with limited fluoroscopy availability.
