ABSTRACT
Difficulty associated with the insertion of the anvil head into the esophageal stump, caused by narrowing of the cervical esophagus, is a big problem for staple anastomosis during esophageal reconstruction. Postoperative cervical stricture also has been a major complication of esophagogastric anastomosis using a circular stapler. The stricture results from esophageal laceration caused by the anvil insertion. To avoid these complications, we designed a new retractor with triple-flap arms, which spreads out in a concentric circle from 20 mm to 35 mm in diameter. This instrument is useful for gently expanding the cervical esophagus without lacerations, and facilitates an anvil insertion into the stump of esophagus. In the 8 patients in whom this instrument was applied for dilation, none of the patients suffered from any stricture. Our clinical result indicates the usefulness of this new instrument for avoiding esophageal laceration and preventing stricture of esophageal anastomosis performed by circular stapler.
