What does anastomotic stricture mean?
After gastric bypass surgery for weight loss, the new connection between the stomach pouch and the small intestine may narrow. This is called an anastomotic stenosis. It’s also known as a stricture.
What is Ileocolonic anastomosis?
An ileocolic or ileocolonlic anastomosis is the joining together of the end of the ileum, or small intestine, to the first part of the large intestine, called the colon. It’s usually performed after a bowel resection in people with Crohn’s disease.
What is Gastrojejunal anastomotic stricture?
A RYGB involves the creation of a gastrojejunostomy (GJ), which connects the distal small bowel to the newly created gastric pouch. Stricture formation or scarring of the GJ following RYGB may lead to narrowing and potential obstruction in these patients.
What do you mean by anastomosing?
An anastomosis is a surgical connection between two structures. It usually means a connection that is created between tubular structures, such as blood vessels or loops of intestine. For example, when part of an intestine is surgically removed, the two remaining ends are sewn or stapled together (anastomosed).
Where is the Gastrojejunal located?
When inspecting the stomach during ERCP, the gastrojejunostomy is usually located along the dependent portion of the stomach. However, it may be slightly off to the anterior or posterior wall along the greater curvature (Figs 24.17A, 24.17B).
How is a gastrojejunostomy performed?
Gastrojejunostomy can be done via either an open or a laparoscopic approach. Percutaneous gastrojejunostomy may be performed, in which a tube is placed through the abdominal wall into the stomach and then through the duodenum into the jejunum.
What are the different types of ileocolonic anastomosis?
There are several configurations of ileocolonic anastomosis, such as functional end-to-end anastomosis (FEEA) and end-to-side anastomosis (ESA) [6]. The end-to-end anastomosis (EEA) is possible only using the handsewn technique.
How is a gastrojejunostomy performed with stomach in situ?
Gastrojejunostomy with stomach in situ. In an antecolic anterior isoperistaltic gastrojejunostomy performed to the native stomach, the jejunal loop is brought anterior to the transverse colon, and the anastomosis is carried out to the anterior wall of the stomach in a side-to-side manner.
How big is an anastomosis after a gastrojejunostomy?
This will create an anastomosis of at least 4 to 5 cm in length. More importantly, it will help guarantee that the emptying from that anastomosis is optimal for its size, because the efferent limb is now situated over the entire anastomotic opening rather than just one end of it with a single-fire stapling.
What causes anastomotic stenosis after gastric bypass?
After gastric bypass surgery for weight loss, the new connection between the stomach pouch and the small intestine may narrow. This is called an anastomotic stenosis. It’s not clear why stenosis occurs after gastric bypass surgery.
