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.

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

October 17, 2011 5:28 pm

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.

It is not in your best interest for us to receive lab results without first having the opportunity to get an update on your health. Due to medical, legal, and insurance issues, we cannot order yearly laboratory studies without first seeing the patient in our office. Some patients may choose to have their labs ordered by their primary care physicians; in that case, we suggest they review the information on our websiteThis is to ensure that we are not ordering tests for patients who will not follow up with us, and that the PCPs who ordered the labs will be able to review the results and make recommendations. 
Over the years, patients have also requested that medication be prescribed solely based on lab results, even if they have not been seen by our office in years.   We will not prescribe medication to any patient who has not been recently seen by our practice. An exception would be for patients or conditions whose treatment we have firsthand knowledge of, that are not new findings based on a patient’s long-term condition. There are cases when a patient calls our office 8 years after surgery asking for Flagyl to treat gas, which we will not prescribe. 

Obesityhelp.com revision Forum information

November 08, 2009 9:00 am

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]

Get informed

September 26, 2009 6:56 pm

As a surgeon, one of my duties is to discuss Informed Consent. There are two components to this, one of which is the consent part. This is where the discussion of risks, benefits, and complications takes place. It is also where options are discussed. A patient cannot give consent if he or she is not informed, which is the second component. The patient should only grant his or her consent if provided with details and every available option.
In my clinical practice, I routinely discuss all the surgical options with a prospective patient. It is my duty to explain in great detail what the surgical alternatives are, what their relative risks are when compared to each other, and the pros and cons of each procedure. Once this information is presented, I would then discuss the rationale as to why certain procedures are superior in certain clinical conditions. It is ultimately the patient who makes the decision as to which procedure is right for the treatment of morbid obesity. In some cases, however, if I do not believe that the procedure the patient has decided on will serve the patient’s long or short-term health needs, I will ask that the patient seek another surgeon.  One of the most common examples of this situation is when patients are seen in my office for surgical treatment of morbid obesity and inquire about the Lap Band®. They have seen an advertisement on television, radio, or even on a billboard. There are even those patients that are told by the primary care physicians that they should ONLY have the Lap Band® done because it will solve all of their problems. The promotional marketing material is only a small portion of a large body of information that is made available to patients and their primary care physicians. To most patients, Adjustable Gastric Banding (Lap Band®, Realize Band®) are “drive-thru” procedures.  They have been advertised as a procedure in which a patient goes to a surgeon’s office, gets examined, operated on, loses weight, and lives happily ever after. This is untrue on a number of fronts and far from the way it actually works for the overwhelming number of patients that get the Lap Band® done. I am not against the adjustable gastric banding procedures. I only advocate that the expectations be set for the patients on an appropriate level.  First of all, the Lap Band® is not for everyone. The scientific information on this matter is overwhelming. The educational booklet that is available and published by Allergan (the manufacturer of the band) has a list of conditions in which the band should not be used. Then there is the relative efficacy of the banding procedure compared to the Duodenal Switch and the Gastric Bypass operation. The questions a patient and a primary care physician should ask:
Are the treatment options effective in both treating and resolving the specified conditions of each patient? 
What are the chances that a patient suffering from diabetes, high cholesterol, or high blood pressure will be cured of these conditions if they have the Gastric bypass, Duodenal Switch, or the Lap Band done. 
The reality is that, in my opinion, most patients opting for the Lap Band procedure have not been educated and provided with the information necessary to make an informed decision. When you consider how little most patients will lose with the Lap Band, one has to realize that the risks, as little as they may be compared to other procedures, are not worth taking.
