Cap-fitted gastroscopy improves visualization and targeting of lesions

Area of Science:

• Gastroenterology
• Endoscopy
• Medical Devices

Background:

• Conventional esophagogastroduodenoscopy (EGD) faces challenges in lesion visualization and targeting due to tangential approaches, tip instability, and
• red-out
• Cap-fitted EGD (CF-EGD) improves visualization and targeting by enabling an
• en-face
• approach, enhancing tip stability and maintaining close apposition.

Purpose of the Study:

• To evaluate the efficacy of a recycled transparent cap for cap-fitted EGD (CF-EGD).
• To assess improvements in lesion visualization and targeting during EGD procedures.

Main Methods:

• A recycled transparent cap from a multiband variceal ligator was utilized during EGD.
• CF-EGD was performed for lesions with suboptimal visualization or targeting.
• Nineteen patients underwent CF-EGD following conventional EGD.

Main Results:

• Lesions were identified in various locations including the duodenum, stomach, and afferent limb (Billroth II).
• Diagnoses included ulcers, polyps, cancer, and metaplasia.
• Targeted biopsies were obtained in 7 patients, 4 bleeding ulcers were treated, and 1 duodenal polyp was removed.

Conclusions:

• The adaptation of a recycled transparent cap for CF-EGD is simple, safe, and effective.
• CF-EGD significantly improves visualization and targeting of gastrointestinal lesions.
• This technique offers enhanced capabilities for biopsy and endoscopic treatment.
