What is closure of mesenteric defect?

What is closure of mesenteric defect?

Closure of mesenteric defects during laparoscopic gastric bypass surgery markedly reduces the risk for small bowel obstruction due to internal hernia. However, this procedure is associated with an increased risk for early small bowel obstruction and pulmonary complication.

What is Petersen’s defect?

Petersen’s space hernia is caused by the herniation of intestinal loops through the defect between the small bowel limbs, the transverse mesocolon and the retroperitoneum, after any type of gastrojejunostomy.

Where is Petersen’s defect?

The mesenteric defect in such cases, called Petersen’s defect, is located between the transverse colon and the mesentery of the alimentary limb (the segment of the jejunum from the jejunojejunostomy until the connection with the proximal segment of the stomach) at the level of the jejunojejunostomy.

What is an internal hernia?

An internal hernia (IH) is defined as the protrusion of abdominal viscera, most commonly small bowel loops, through a peritoneal or mesenteric aperture into a compartment in the abdominal and pelvic cavity (1-3).

What is a mesenteric defect?

Congenital or acquired defects of the mesentery with internal hernia can present as small bowel obstruction and lead to incarceration or strangulation of the bowel. Mesenteric defects are usually 2–3 cm in diameter.

What is contained in the mesentery?

The mesentery is an organ that attaches the intestines to the posterior abdominal wall in humans and is formed by the double fold of peritoneum. It helps in storing fat and allowing blood vessels, lymphatics, and nerves to supply the intestines, among other functions.

What is Petersen’s space?

Petersen space is the defect space that can sometimes occur in the mesentery between the alimentary loop of a gastrojejunostomy and the lower part of transverse colon mesentery after a gastric surgery. 1. One of the complications that can arise following any type of gastrojejunostomy is a Petersen space hernia.

What are the warning signs of a hernia?

Signs and Symptoms of a Hernia

• An obvious swelling beneath the skin of the abdomen or the groin.
• A heavy feeling in the abdomen that sometimes comes with constipation or blood in the stool.
• Discomfort in the abdomen or groin when lifting or bending over.
• A burning or aching sensation at the bulge.

What causes a mesenteric hernia?

Mesenteric defects are usually the consequence of previous surgery and most often revealed by acute intestinal obstruction. Their discovery during diagnostic workup of chronic abdominal pain is less frequent. Other causes are much more rare: trauma, inflammation, or congenital defect.

What are symptoms of internal hernia?

In mild cases, individuals may not have any symptoms at all. In more severe cases, an individual may experience mild abdominal discomfort or severe abdominal pain. Individuals may also experience vomiting, nausea, constipation, and abdominal tenderness.

Can you live without a mesentery?

It is made of a folded-over ribbon of peritoneum, a type of tissue usually found lining the abdominal cavity. “Without it you can’t live,” says J. Calvin Coffey, a Limerick University Hospital researcher and colorectal surgeon. “There are no reported instances of a Homo sapien living without a mesentery.”
