Periprocedural Care


Equipment required for laparoscopic gastric bypass (GBP) includes the following:

  • Laparoscopic tray with full set of instruments, including graspers, dissectors, endoscopic gastrointestinal anastomosis (GIA) staplers, and silk and polyglactin sutures
  • Energy source
  • Staple-line reinforcers (eg, Seamguard)
  • Trocars, 5 mm and 10-12 mm
  • Orogastric tube
  • Nathanson liver retractor

Patient Preparation

General anesthesia is required for a laparoscopic GBP procedure.

The patient is positioned either supine with the arms extended outward or in the lithotomy position, depending on the placement of the trocars. The surgeon should be standing comfortably with the arms and elbows in an abducted position.
