Ileocecal Valve Lesions No Longer Defy Endoscopic Resection

Laterally spreading lesions on the ileocecal valve (ICV) have traditionally been among the most challenging to resect endoscopically, and some centers refer them for surgical resection if they are very large, completely encircling the valve, or penetrating the ileal lumen.
Over a 12-year period ending in October 2020, a consortium of Australian investigators removed 142 laterally spreading ICV lesions 20 mm or larger in size. They divided these lesions into a historical cohort of 76 lesions and a contemporary cohort of 66 lesions.
The resections in the contemporary cohort versus the historical cohort had a higher success rate (94% vs 78%, respectively), were shorter in duration (40 vs 60 minutes, respectively), and had a lower recurrence rate (4.6% vs 21%, respectively). Snare tip soft coagulation treatment of the colonic side of the EMR margin after resection was used for nearly all of the contemporary cohort versus 6% of the historical controls.
