Core Tip
Core Tip: Currently, most clinicians prefer endoscopic procedures for the treatment of stenosis after colorectal anastomoses, including dilation, electrocautery incision, or radial incision and cutting (RIC), because they have lower complication rates than surgery and are less invasive. Here, we report the use of endoscopic RIC alone with single session for two patients who presented with treatment-naive anastomotic stenosis (AS) after colorectal anastomosis. The endoscopic RIC procedure may play a role as one of the treatment options for treatment-naive, central-type AS with short stenotic lengths and for AS confined to the mucosa and submucosa.
