NOVEL USE OF RIGIDIZING OVERTUBE FOR ENDOSCOPIC ULTRASOUND-DIRECTED SAMPLING OF A CECAL SUBEPITHELIAL LESION

Video Transcription

Video Summary

The video presents an innovative use of a rigidizing overtube for endoscopic ultrasound (EUS)-guided biopsy of a subepithelial lesion proximal to the rectal sigmoid colon, areas typically challenging for tissue sampling. A 71-year-old patient, whose lesion couldn't be diagnosed through conventional methods, underwent EUS with a rigidizing overtube—a technique not previously reported. This method allowed safe, minimally invasive access to the proximal colon, yielding diagnostic tissue samples and avoiding surgical interventions. The procedure proved technically feasible, enhancing diagnostic accuracy and could potentially expand to other therapeutic applications like transluminal fluid drainage.
