As I was looking over old archives, I came across the following pictures that were taken years ago. These were photographs taken to demonstrate the technique for the construction of the anastomosis of the biliopancreatic channel and alimentary channel of the Duodenal Switch.
The steps of doing the stapled anastomosis of the Duodenal Switch is generally unchanged during the laparoscopic approach to the procedure.
The stitches are placed to secure the bowel together. Two small openings are made in each limb of the bowel to be stapled together (the biliopancreatic limb on the bottom and the alimentary on the top of the image).
It is important to also align the bowel in the same peristalsis direction. This means that the contraction and the relaxation motion of the bowel should all point in the same direction. This should reduce the risk of complications such as intussusception.
When the stapler is fired in opposite direction, a very wide anastomosis is created.
Once the anastomosis is created, then the last staple is used to close the opening that was made. This staple line is perpendicular to the direction of the anastomosis to avoid making the opening narrow.
