What causes fistula after gastric bypass?

Gastro-gastric fistula is a communication between the gastric remnant and gastric pouch. It is a rare complication of Roux-en-Y gastric bypass. It is caused by anastomotic leak, marginal ulcers, distal obstruction or erosion from foreign body.

What is gastro-gastric fistula?

Gastrogastric fistula is a communication between the proximal gastric pouch and the distal gastric remnant. Fistula formation, although a commonly described phenomenon in various gastric operations and disease processus, rarely has been described in the realm of bariatric procedures.

What is a fistula after gastric bypass surgery?

Gastro-Gastric Fistula is a known rare complication after Gastric Bypass surgery, opening an abnormal communication between the excluded gastric remnant and the neo gastric pouch. It can lead to weight regain, marginal ulcers and epigastric pain.

What are the symptoms of a stomach fistula?

What are the signs and symptoms of a GI fistula?

What can cause a gastric leak?

Some leaks are due to technical difficulties during surgery, but others are due to patient-related factors such as poor nutrition, recent or current smoking history, liver cirrhosis, or renal failure [2]. Also, depending on their severity, a leak may be either subclinical or clinical [4].

Can a fistula cause weight gain?

When a fistula is present, it is usually followed by weight gain, abdominal pain or refractory ulcers. Fistulization between gastric segments is a late complication after (RYGBP).

What is cutaneous fistula?

An enterocutaneous fistula (ECF) is an abnormal connection that develops between the intestinal tract or stomach and the skin. As a result, contents of the stomach or intestines leak through to the skin.

Why is Gastrojejunostomy done?

Gastrojejunostomy is a surgical procedure in which an anastomosis is created between the stomach and the proximal loop of the jejunum. This is usually done either for the purpose of draining the contents of the stomach or to provide a bypass for the gastric contents.

What is gastric leakage?

One risk of a gastric bypass is digestive juices and partly digested food leaking through an anastomosis. This is a serious complication after gastric bypass surgery. A leak may happen up to several weeks after surgery. Most occur within a few days after surgery.

This abnormal connection is known as a gastro-gastric fistula. In a patient who may have a gastro-gastric fistula, the food can travel down the gastric bypass path or enter the bypassed stomach and go down the path of a normal anatomy. In these cases, the physiological effect of a gastric bypass procedure becomes ineffective.

What are the risks of gastrogastric fistula surgery?

However, the procedure is not risk-free, especially during the learning curve. Major complications include bowel obstructions, anastomotic leaks and strictures, gastrogastric and gastro-cutaneous fistulas. Gastrogastric fistula is a communication between the proximal gastric pouch and the distal gastric remnant.

What causes fistula formation after gastric bypass?

Fistula Formation. Even after transection of the stomach during gastric bypass, late staple-line failure can occur developing fistulous communication between the proximal pouch and the distal stomach if the pouch remains close to the bypassed stomach.

What percentage of gastrointestinal fistulae are caused by surgery?

About 90 percent of the gastrointestinal fistulae occur as a result of surgical procedure complications. In a research done on 1,148 people who underwent abdominal medical surgery, it was found that about 6 percent of the participants later got fistula.
