A patinet story: Lap Band complication and Wagovy
October 24, 2024 4:30 pm
Not too long ago, I saw an old patient who had seen me years ago after having had a lap band placed for weight loss. At the time, I recommended that the lap band be removed and that alternative plans be made. I suspected a slipped band. We discussed the reality that after the band removal, weight gain is to be expected. Several surgical options were discussed, and the patient dismissed them as “too radical.” The patient decided to “deal” with the ongoing nausea and vomiting since it was a small price to pay for the weight loss. I warned the patient that elective removal of the band is much safer than an emergency procedure in the middle of the night when it is least convenient. The patient did end up with an emergency lap band removal and was started on GLP-1 Agonists (Wagovy) because of the weight gain that followed the band removal. The side effects of the medication were debilitating, with nausea, dizziness, and fainting due to low blood sugar. The drug has all been stopped, and most, not all, of the side effects are resolved. The plan is to get this patient in a better shape and, reevaluate the esophagus and the stomach, and formulate a strategy based on the blood work, upper endoscopy, upper GI study findings and decide if the patient will be a good candidate for the Laparoscopic sleeve or the duodenal switch operation.
Here are my recommendations:
- Patients should avoid lap bands. Those with lap bands, regardless of how they feel and whether they are having issues with them, should have the lap band removed immediately before they end up in the emergency room or have irreversible changes to the cells or function of the stomach and esophagus.
- Patients who have the lap band removed will have less weight loss with the sleeve than those who have the sleeve as the primary procedure (the lesson here is that a less invasive, seemingly easy solution is much worse long term; more on this below). Lap Band patients should be revised to the duodenal switch, SPIS, SADI, or Gastric bypass if they have substantial weight to lose.
- GLP-1 agonist medication should be avoided. It is not a solution to the underlying problem but a band-aid covering the metabolic derangement.
- GLP-1 agonist medication needs to be taken long term, and there is no exit strategy– when the patients stop taking the drug, the weight comes back, in addition to the complication associated with it.
- I have also heard that “if it were bad, then the FDA would not approve it.” well, let’s think about it: the FDA approved the Lap band and Phen-Fen, and we all know how these worked out.
- There are no shortcuts, simple injections, or a pill for the complex, multifaceted condition of obesity. Advocating solutions with no long-term outcome, significant complications, and safety concerns is irresponsible.
- A diabetic patient should take the medication LIFELONG to control their blood sugars, including the GLP-1 agonist class of drugs. The concerns are for these medications being used for the treatment of obesity,
SUMMARY: Buyers beware- those who choose to embark on the dangerous load of GLP-1 agonist medications should be prepared to deal with the short and long-term complications of the medication and its withdrawal. This is like the problems that are being seen with patients who choose to have a lap band because it was advocated as simple, reversible, and the Phen fen medication for weight loss with the associated cardiac complication.

October 06, 2024 9:17 pm
The Lap Band was approved in the US in 2001 (BMI> 40). The following studies used only small samples and examined short-term efficacy and safety. They were then performed to consider the utility of the Laob band for patients with lower BMI (BMI 30-40). 
Noe the frequent complications of nausea, difficulty swallowing, pain, and reflux-which may sound familiar to a lot of patients who have had and still have the Lap Band.
Numerous US and international studies have been published over the years, including short-term and long-term studies. The summary outcome has been the same, with only a few exceptions.
- The Lap Band does not result in long-term sustained weight loss.
- Lap band has significant complications, some of which may not be reversible.
- The lap band can be removed, but eroding the banc to the stomach is not easy.

Medication Absorption After Weight Loss Surgery
March 30, 2020 8:01 am
Weight loss surgical procedures, in one form or another, achieve the desired effect of weight loss by altering absorption of fat, protein, and carbohydrates. This results in decreased total absorption of required calories.
An unintended consequence is the altered absorption of medications. Frequently I am asked about the specific medication. Usually the answer is vague since the information is limited on specific medications. If the desired effect is not achieved, then it is probably not being absorbed well. Specially, if the same dose of the same medication working well before surgery.
There is a summary article about the Theoretical absorption pattern of different weight loss surgical procedures.

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.
SIPS, SADI-S, Loop DS
May 01, 2019 9:03 am
The American Society for Metabolic and Bariatric Surgery (ASMBS) and MBSAQUIP-A on March of 2019, published and updated list of “Endorsed Procedures and Devices”
Endorsed Procedures and Devices | American Society for Metabolic and Bariatric Surgery
Note that any surgical procedures that does not employ two anastomosis, are not endorsed and are only recommended to be performed with an IRB (Institutional Review Board) or an IRB exemption. Duodenal Switch, Sleeve Gastrectomy, Roux en Y Gastric Bypass, Gastric Balloon, Adjustable Gastric Banding, and Nerve Blocking which are endorsed procedures.
SIPS, SADI-S, SIPS, Loop DS are all in the category of the “Non-Endorsed Procedures and Devices”. To see an anatomical comparison of these procedures to the Duodenal Switch procedure.
Patients should request that their consent be clearly defined and should explicitly outline the procedure that is being proposed to them. This is to avoid a patient having a procedure that they assumed, or are led to believe to be a Duodenal Switch operation with two anastomosis. Do your due diligence and know the procedure you want. Investigate if the surgeon you are working with performs the procedure you are interested in. Have them draw a picture of the procedure or give you a diagram of the procedure.
Cholecystectomy-Gallbladder Removal
September 10, 2018 9:44 am
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.
