Abstract:
In 1994, Wittgrove and Clark first described the laparoscopic technique for the Roux-en-Y gastric bypass. Many techniques have been used over the years, mostly based on the use of linear and circular stapling devices for the two anastomoses-the jejeunojejunostomy and the gastrojejunostomy. In 2000, Dr. Kelvin Higa from Fresno described a different technique, with the performance of a hand-sewn gastrojejunostomy. In this article we do review our technique, which is based on Dr. Higa's initial description. The steps of the operation will be illustrated by intraoperative pictures.
