EUS-guided rendezvous fistula creation for complete anastomotic stenosis after low anterior resection.

ABSTRACT:

Background and aims

Complete luminal stenosis at the colorectal anastomosis after low anterior resection is a rare adverse event.

Methods

We present a novel case with rendezvous via a diverting ileostomy and a retrograde EUS-guided formation of a new colorectal anastomosis for recanalization.

Results

A 52-year-old previously healthy man presented with rectal bleeding and was found to have locally advanced (T3N1) adenocarcinoma. The patient received neoadjuvant chemoradiation and then underwent an uncomplicated low anterior resection with a diverting loop ileostomy. During surveillance sigmoidoscopy 6 months later, complete stenosis of his anastomosis was seen, and he was referred to advanced endoscopy. He underwent dual-operator colonoscopy and ileoscopy with confirma
