Sleeve Gastrectomy Failure
May 07, 2019 12:53 pm
Sleeve gastrectomy (SG) is the most commons performed weight loss surgery in the US. There is a subset of patients for which Sleeve Gastrectomy will be inefficient/ineffective. Sleeve Gastrectomy failure may be defined as inadequate weight loss or weight regain. However, in some cases this may also include non resolution of some of the co-morbidities of obesity, and/or recurrence of others.
Biertho, et. al, (Surgery for Obesity and Related Diseases 14 (2018) 1570–1580) Published a study titled “Second-stage duodenal switch for sleeve gastrectomy failure: A matched controlled trial” where 118 patients were decided in two groups. One group had the duodenal switch as a singe procedure, and the second group had the sleeve gastrectomy followup by the second stage duodenal switch. They concluded that “Second-stage DS is an effective option for the management of suboptimal outcomes of SG, with an additional 41% excess weight loss and 35% remission rate for type 2 diabetes. At 3 years, the global outcomes of staged approach did not significantly differ from single-stage BPD-DS; however, longer-term outcomes are still needed.”
They showed that the remission rate of the obesity related co-morbidities were improved.
The weight loss rate that had stopped, or in some cases where weight gain had been noted, were both reversed where by at at average of 24 months after addition of the DS to the SG patients would experience additional 39% Mean excess weight loss.
With regards to alternative approaches they indicate “ Other forms of revisions have been described, (i.e., adjustable or nonadjustable gastric band, plication, endoscopic balloon), with limited scientific evidence on their efficacy or safety. These procedures are mostly considered investigational and should be performed under Ethical Review Board approved protocols.”
In summary, patients may be offered a number of alternative if they are experiencing weight regain, inadequate weight loss, or return of co-morbidities after sleeve gastrectomy failure. We have seen a variety of them in our office. Patients who have had band placed on the sleeve, or are scheduled to have gastric balloons placed. As I have always said, buyers beware and know your outcomes and resolution of co-morbities.
Duodenal switch operation, (not the single anastomosis look alike) results in sustained weight loss and resolution of the co-morbidities. A second stage Duodenal Switch can mean adding the intestinal procedure to an existing Sleeve Gastrectomy. Some patients have required an adjustment to their Sleeve Gastrectomy in addition to adding the Duodenal Switch intestinal portion. Finding the right balance for each patient is a crucial part of our practice.

There are differing opinions, based on a broad set of scientific publication, wether or not gallbladder should be removed at the time of weight loss surgery. Obviously, Cholecystectomy is a stand alone general surgical procedure that is often performed due to gallstones and/or gallbladder disease with a variety of symptoms. However, the focus of this blog will deal with Bariatric Surgery and Cholecystectomy.
Rapid weight loss can increase a patients chance of forming gallstones. This rapid weight loss can be as little as 3-5 pounds per week. Weight loss surgery can increase your risk for gallstone formation. Several of the common thought processes the mechanism of this is, obesity may be linked to higher cholesterol in the bile, larger gallbladders, high fat diet and larger abdominal girth.
When a patient is having the Duodenal Switch (DS) Bariatric operation, or having a revision of a failed gastric bypass to the DS, I always remove the gallbladder. This is because there isn’t an anatomical route to utilize endoscopic procedure for an ERCP should the need rise.
In the case of a patient undergoing Vertical Sleeve Gastrectomy, if there are any indications or complaints of abdominal pain then an ultrasound is done. If there are findings of gallstones or other disease of the gallbladder, then a cholecystectomy is performed at the same time as the Sleeve Gastrectomy.
In my opinion, every patient having the Gastric Bypass (RNY) should also have the gallbladder removed because of the anatomical limitations after surgery that prevents the use of ERCP if needed. Some clinicians will place the patient on a long term medications to reduce the chance of gladstone formation after surgery, which themselves have side effects limiting the compliance in most patients.

PolyCystic Ovarian Syndrome PCOS
September 04, 2018 9:58 am
PolyCystic Ovarian Syndrome PCOS is a complex condition. The exact cause of PCOS is unknown however, it involves hormones imbalance and multiple ovarian cysts, irregular menses, and infertility. In some cases, PCOS can be compounded by diabetes, hypertension and other metabolic conditions. PCOS has been shown to effect approximately 10% of women of childbearing age with symptoms of menstrual abnormalities, poly cystic ovaries, and excess androgen (male sex hormone). PCOS should be diagnosed by ensuring there are no other underlying endocrine issues. There are several associated disease processes that seem to be related to PCOS. These related disease processes are Type 2 Diabetes, higher depression and anxiety, increased cardiovascular risks, stroke, hyperlipidemia, sleep apnea, overall inflammation, and endometrial cancer.
Anatomically, numerous cysts are found on the ovaries. These are usually diagnosed by ultrasound, blood levels of hormones, and symptoms described above.

Revision from failed AGB to Duodenal Switch
January 10, 2018 2:10 pm
A few times a month during consultation for weight loss surgery , I’m ask as to why I do not offer the adjustable gastric banding as an alternative to the patients. As I have said over the years when a patient considers an weight loss surgery the totality of the risk should be considered. This includes the operative, immediate postoperative course, the maintenance and the follow-ups needed. The potential complications of the procedure in addition to the long-term success off each operation should also be taken into account.
Unfortunately, some patients are led to believe that any perceived benefit in the short operative time and the ease of the adjustable gastric banding also translates to a better outcome. This is in fact the opposite of what the published data have shown, a recent study published in April 2017 by Vinzes et.al, shows that 71% of patient lost their band by 10 years out.
What is also interesting that more patients underwent revision from failed AGB to the duodenal switch than the sleeve gastrectomy (Fig 1.). This is what I also recommend.
More importantly, The patients who underwent a revision from failed AGB to the duodenal switch operation had the best long term results of all patients (Fig 2.) note the “rBPD” line that is the highest of %EBMIL.
Complication’s were broad and frequent (Table 3.)

Long Term Complications of Adjustable Gastric Banding
October 17, 2017 6:35 am
It is interesting to encounter patients who are still being recommended for Lap Band placement to treat morbid obesity. There is a vast body of scientific evidence supporting that Lap Band not only does not result in a sustained weight loss for majority of the patients, but that it results in significant long term complications for some.
One of the complications is a significant stricture (narrowing) where the band is located even when it is completely empty. This is cause by:
1- either scarring of the tissue around that band causing a “belt” effect around the stomach, or
There are numerous other complications that are associated with Adjustable Gastric Bands that encompass a wide range of areas that are not discussed in this blog. This recent article (yes another one) outlines the dismal long term outcome of the Adjustable Gastric banding- Buyer Beware.
Gastric Band Complications
June 21, 2017 10:22 am
For years, we have seen patients who have had Adjustable gastric bands placed and continue to suffer from the complications associated with it. Gastric Band complications include erosion, persistent nausea, vomiting abdominal pain, inadequate weight loss and weight regain, etc. . Unfortunately, when seeking help, they are often told that this never happens to others and that complications are a rare occurrence. Let’s remember that the Adjustable Gastric Band was promoted and sold as a procedure with almost no down side, low risk and easily revisable!
There is an unfounded expectation that the band can be deflated and all the Gastric Band complications will resolve. This could not be any further from the truth. The reality is that there are patients whose symptoms may somewhat improve but will continue to have the abdominal pain, the nausea and or vomiting-albreit, not to the same intensity. There are several Gastric Band complications that are considered emergency situations that require immediate attention by a physician.
Our position has always been, and continues to be, that all Adjustable Gastric Bands should be removed by a surgeon who is experienced with the Gastric Band complications and revisions.
Slipped Band Emergency
April 27, 2017 12:35 pm
A slipped Band emergency
This patient had a Adjustable Gastric Band (AGB) or LapBand place approximately 7 years ago. The last time this patients had a follow up with the surgeon who placed the AGB was 5 years ago. The patients has been having reflux, episodes of Nausea and vomiting on and off for about 2 years requiring multiple medical visits and procedures. He/she has had upper endoscopies, not by the surgical team and was diagnosed with esophagitis.
This patient presented in the Emergency Room with projective vomiting for 24 hours, bloody emesis, and significant dehydration. After obtaining the necessary tests and X-ray studies a plan was constructed. At this time, due to the continuous and significant nature of the symptoms this patient was taken to the Operating Room for emergency AGB removal.
The abdominal X ray showed a slipped band. Following a complicated surgical procedure, the band was removed and a segment of the stomach that had eroded into the stomach was removed. The photograph below shows the end result with a portion of the stomach removed due to the band’s erosion into the stomach.

Weight Gain after Gastric Bypass
January 04, 2017 9:12 am
Weight loss surgical procedures have different long term results and some procedures have more dramatic weight loss than others. Some procedures also result in much more sustained and long term weight loss. Unfortunately, what may be not obvious is that the patient has very little control over the outcome of the surgery in most cases. IT is very easy to blame the patient for weight regain after weight loss surgery. However, it is important to remind ourselves that the long term data reporting outcomes of the surgical procedures in most cases, includes all patient population. All these studies include the most compliant and not so compliant patients. Comparison chart of outcomes of weight loss surgical procedures.
A larger percentage of gastric bypass patients will require revision for weight regain, or other problems. There is no evidence that the size of the pouch or the anastomosis between the pouch and the small bowel changes the weight regain outcomes. Yet, quite frequently I will see patient who have had gastric bypass revision for weight regain, by reducing the size of the pouch or the anastomosis. Here are some publications that support the notion that other than extreme dilation, the size of the pouch and the size anastomosis does not predict the outcome of the surgery. There is some correlation with the site of the pouch, anatsmosis and weight loss, but there is no correlation between the size of the pooch, the opening and the failure rate. This means that patient with smaller pouch do not have better long term outcome that the ones with larger pouch, only that the patient with smaller pouch or anatsmaosis will loose more weight.
“Influence of pouch and stoma size on weight loss after gastric bypass”
“Impact of gastrojejunostomy diameter on long-term weight loss following laparoscopic gastric bypass: a follow-up study”
Weight regain after RNY Gastric Bypass may also be caused by a Gastro-gastric fistula, which is a new connection between the pouch and the remnant stomach. Here is further information on Weight Loss Surgery Revisions.
When considering a primary weight loss surgical procedure, be informed. Investigate all your options and consider the long term outcomes. This may mean investigating different weight loss surgical procedures on your own.
Curved Adjustable Gastric Band Discontinued
May 19, 2016 11:19 am
The Curved Adjustable Gastric Band will be discontinued. Johnson and Johnson, the parent company of the Ethicon, is removing the Curved adjustable Gastric Band from its’ product line. This particular band is known as the Realize Band launched by Johnson & Johnson and did not gain much traction. The number of Adjustable gastric band placements have gone down significantly as the data have shown poor outcome over long term and a high complication and re-operative rates.
The following link is a copy of the letter from Ethicon Johnson and Johnson regarding the Curved Adjustable Gastric Bands Discontinuation: Realize Band removed from the Market.
