Abstract
Laparoscopic Roux-en-Y gastric bypass was recently introduced as an alternative surgical treatment for morbid obesity. The technique involves placement of a 21-mm anvil transorally down to the gastric pouch for creation of the gastroenterostomy anastomosis using an EEA stapler placed transabdominally. Esophageal injury is a theoretical concern with transoral manipulation of the anvil. The authors present a case of hypopharyngeal perforation after an attempted transoral insertion of an EEA anvil. The perforation was treated with neck exploration and drainage. We discuss the mechanism of injury and alternative method for placement of the gastric anvil.
