Laparoscopic sleeve gastrectomy

Position the camera trocar in the left upper quadrant, ensuring it is at least 15 cm away from the xiphoid.

Insert another two 12 mm trocars in the median epigastrium inferior to the rib cage. Place a 5 mm trocar high up in the median epigastrium.

Skeletonize the greater curvature of stomach by transecting the gastrocolic ligament close to the gastric wall, while preserving the gastroepiploic arteries. Start the distad dissection with the Ultracision at the inferior gastric body, ending 3-5 cm proximal of the pylorus. Open the lesser sac and take down any adhesions to the pancreas.

In this way, release the entire greater curvature of stomach. Divide the connection to the spleen, the gastrosplenic ligament, and clip the short gastric vessels. Carry the skeletonizaton through to the angle of His.

Note: Expose the angle of His with the left diaphragmatic crus to rule out any hiatal hernia and parts of the stomach displaced into the mediastinum.
