Gastro-gastric fistula after gastric bypass operation
May 10, 2013 9:09 pm
One of the complications of gastric bypass is a gastro gastric fistula. This happens when a connection between the gastric bypass pouch develops to the remnant stomach. In a gastric bypass operation, a very small pouch is created from the stomach, and connected to a segment of the small bowel.
The purpose of this operation is to decrease over 95% of the volume of the stomach. In theory, the benefits of this is to reduce the volume of food that can be consumed. Over time, the size of the stomach pouch, and/or size of the gastro-jejunostomy anastomosis might stretch. This result in weight regain that is very commonly seen in about 3 years after a gastric bypass operation.

Another possible explanation for weight regain may be an abnormal connection that may develop over time between the bypassed stomach and the small pouch that was created. 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.
The treatment that I favor most for correcting the complication of the gastro-gastric fistula is is to revise the gastric bypass to the duodenal switch operation.

Yearly lab and medication requests

As the years pass, weight-loss surgery patients, like everyone else, will require routine screening for certain chronic conditions. What is important is ensuring your primary care team is aware of the need for specialty testing to monitor vitamin and mineral levels.
You should also check with one of the labs and your insurance company to make sure they are a contracted facility and that the order is covered under your policy. It is your responsibility to ensure that your insurance company will pay for the ordered labs. We are in no way responsible for verifying the benefits of the laboratory services we order.
It is critical that patients who have undergone weight-loss surgery receive continuous annual follow-up care and monitoring. It is critical that patients continue to receive yearly follow-up care, not only by completing their scheduled laboratory studies but also by attending an in-office follow-up exam. Patients are welcome to contact our office and schedule an in-person or virtual follow-up.
Obesityhelp.com revision Forum information

I am not sure what has happened over the past two weeks or so, but I have received a number of inquiries from patients who have had questions about the revision of RNY or Lap Band® for weight regain, inadequate weight loss, or other complications. I finally had to ask one of the patients where he got his information and heard about our practice. His source of information was the obesityhelp.com website.
I have spent some time looking over and responding to several postings on the forum sites. I have referred to a number of publications in some of my postings on obsityhelp.com.
Nishie et.al. (Obesity Surgery, 17, 2007 1183-1188) reported:
“Pouch size area, measured by routine UGI on the first postoperative day does not influence short term postoperative weight loss. “
Cottam et.al. (Obesity Surgery 2009, 19:13-17) concluded:
“The level of restriction or the presence of stenosis achieved by different stapler sizes does not have a significant role in weight loss.”
O’Connor et.al. (Surgery for Obesity and Related Dis. 4(2008) 399-403) summarizes:
“With construction of divided, vertical, lesser curvature based small-volume (less than or equal to 20 cm gastric pouches, the actual size of the gastric pouch did not correlate with the %EWL at 1 year laparoscopic GB.”
I am a firm believer that the best patient is the most knowledgeable patient. It is always safer to spend as much time as needed to ask questions and investigate all options. If I can provide any information, please contact us at [email protected]
