Road Map fluoroscopy successfully guides endoscopic interventions in the esophagus

Area of Science:

• Radiology
• Gastroenterology
• Endoscopic Interventions

Background:

• Road Map (RM) fluoroscopy, a radiological technique using image subtraction, has not been previously evaluated for endoscopic applications.
• Esophageal strictures often require endoscopic interventions that can benefit from enhanced imaging guidance.

Purpose of the Study:

• To evaluate the utility and safety of RM fluoroscopy in guiding endoscopic interventions within the esophagus.

Main Methods:

• A monocentric observational trial involving 24 patients with esophageal strictures undergoing 27 RM-guided endoscopic procedures.
• Interventions included balloon dilatation, bougie dilatation, diagnostic endoscopy, and the placement of 12 esophageal stents (partially and fully covered).

Main Results:

• RM fluoroscopy successfully guided all endoscopic interventions.
• Endoscopic control confirmed accurate stent placement in all cases where stents were deployed.

Conclusions:

• RM fluoroscopy provides accurate and permanent radiographic imaging of esophageal stenoses and anatomical changes.
• It is a safe and effective method for guiding endoscopic interventions requiring radiological visualization.
