The 'do-it-yourself' silastic ring for the silastic ring Roux-en-Y gastric bypass

摘要

A silastic ring can limit gastric pouch distension and weight regain. We manufacture a ring using an 8Fr silastic catheter and a length of 2/0 polypropylene (Fig 1). The catheter is cut to the intended circumference. A small incision is made lcm from one end of the catheter, allowing access to the lumen. The polypropylene is passed behind the gastric pouch and brought extracorporeally. Both ends are introduced into the lumen. The ring is positioned using a knot pusher and the polypropylene knotted. A 2/0 braided polyester suture is placed between the cut ends. The ring is cheap to make and easily removed.
