Bidirectional Jejunojejunal Anastomosis Prevents Early Small Bowel Obstruction Due to the Kinking After Closure of the Mesenteric Defect in the Laparoscopic Roux-en-Y Gastric Bypass.

Enlarging the JJS with a bidirectional linear stapling is associated with a reduced risk of early SBO due to the anastomosis kinking. However, it could be related to an increased risk of digestive bleedings.
