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.

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.
Bile Reflux Gastritis

Bile Reflux
Bile Reflux is primarily a diagnosis of exclusion. All other possible causes must be ruled out, and bile reflux gastritis is made with the pertinent symptoms. The reason for this is that there is no primary test that can prove the diagnosis. When it comes to treatment, the surgical option requires preventing the bile from coming back to the stomach. The procedure we have performed routinely for bile reflux gastritis is the duodenal switch (without a reduction in the stomach size). This allows the food to go through an intact stomach and pyloric valve with normal stomach physiology (to prevent dumping syndrome). The bile is diverted through 100 cm of the small bowel as the biliary and alimentary limbs to prevent backflow of bile to the stomach (if it’s made too short). The procedure referenced (https://www.americanjournalofsurgery.com/article/S0002-9610(03)00213-7/abstract) is nearly 20 years old. It is rarely, if at all, performed due to its very complex and relatively high-risk nature. Its primary role for a surgeon is to reconstruct the biliary track flow. This operation involved transecting the common bile duct and creating a biliary tree to small bowel anastomosis. This is, at times, done when there is injury, obstruction, or tumor of the bile duct. This anastomosis has its complications, including stricture and sump syndrome. Therefore, hepaticojejunostomy or hepato-duodenostomy anastomosis are reserved for cases with no alternatives.

Covid 19:Anesthesia, Weight Loss Surgery and Malnutrition
October 30, 2021 8:52 am
As the COVID-19 pandemic is charting its course into 2022, as health care providers, we have had to adapt and adjust to the transient and shifting environment. Testing for COVID-19 has been in place, and is now part of the standard for preoperative work-up. In addition, covid testing will likely be part of screening any surgical procedure for the foreseeable future.
The challenge of pandemic control is the large pockets of populations in the US and worldwide that do not have protection against the virus and are not vaccinated. Vaccination provides the only proven long-term protection against COVID-19 infection and its long-term persistent health effect. In addition, the complication rate reported in scientific journals is negligible compared to the complication and death rate from the COVID-19 infection.
There are implications of covid infection and general anesthesia published in peer-reviewed journals. The increased risk of general anesthesia after covid infection is related to the severity of the initial infection and the extent of the treatment required, and the persistence of the post covid symptoms, including shortness of breath, fatigue, and laboratory finding elevated inflammatory markers. Long after resolution of the acute COVID-19 symptoms, the most common persistent complaints are fatigue, shortness of breath, Joint and chest pain; and all these increase the risk of post-operative complications (Carfì et al., 2020)
The required delay for surgery may be as short as 2-4 weeks to as long as six months or longer if the persistent symptoms are present. Surgery may not be avoidable in a critical life-threatening situation and may be necessary even with a much-increased risk of complication (Collaborative, 2020). Recovery post-COVID-19 may not be complete with the resolution of the initial symptoms (Dexter et al., 2020)
Recent publications and scientific presentations have also shown the protection that weight loss surgery and maintained weight loss provide in those who come down with the COVID-19 infection (Aminian et al., 2021). However, the rate of weight gain, lack of weight loss is worse for weight loss surgical patients post COVID-19 disorder (Bullard et al., 2021; Conceição et al., 2021). Furthermore, patients with COVID-19 infection post weight loss are at a higher risk of malnutrition (di Filippo et al., 2021; Kikutani et al., 2021). Up to 40% of patients have malnutrition if hospitalized with COVID (Anker et al., 2021).
To summarize, Weight loss and weight loss surgery reduce the severity of the initial COVID-19 infection. However, it increases malnutrition risk, requiring nutritional support and surgical interventions in non-responsive cases.

COVID Vaccines
March 05, 2021 3:50 pm
There are no known contraindications from a weight-loss surgical perspective to prevent a post-surgical patient from getting the COVID vaccines.
A patient who has had a Duodenal Switch, Lap Sleeve Gastrectomy, RNY Gastric Bypass, or revisions to Weight Loss Surgery should have the COVID vaccine. The vaccination should be avoided for a few weeks after surgery. For other possible contraindications, please consult your PCP.
Here is a summary of the vaccines and the details of each one approved as of the publication date.
Physical Activity in US
November 28, 2020 1:41 pm
Physical activity in the U.S. varies based on geographic location, socioeconomic status and in comparison to other countries. It is important to know that physical activity is an important component of our well-being. However, this does not mean that going to the gym is the only way to be physically active.
Strain et al. Shows that different populations in different countries get their activity from different sources.
His research showed that the United States population ranked as a high-income country, ranks in the lower 1/3 of the number of countries surveyed with regards to the meeting minutes of moderate-to-vigorous physical activity (MVPA) per week. This may be a contributing factor to the significant rise in obesity in the United States. Individually we should all aim to increase our moderate to vigorous activity significantly.

Vitamin D and COVID 19
June 13, 2020 4:40 pm
There has been extensive discussion on the importance of Vitamin D published over the last few years in regards to bone health, immune health and Calcium physiology. The importance of vitmain D and bone structure has been discussed extensively. It is also important in the absorption of Calcium. It further plays role in immune modulation.
What is new is the possible correlation of Vitamin D and COVID 19. Recently it is been shown that low vitamin D may increase the risk of a poor outcome with Covid-19 exposure and infection.
There are different standard recommendation for the Vitamin D levels.
In our practice we aim to maintain a Vitamin D level of 0ver 60 in post weight loss surgical patients.
There are a number of theories as to how the Vitamin D deficiency may play a role in this. An emerging observation is that low Vitamin D may cause abnormal and excessive blood clot formation. Mohammad et. al. in 2019 published a study on the association of low vitamin D and “…Pathogenesis of Thrombosis”
This pathologic blood clot formation in COVID-19 patients may explain the extensive lung injury and multi system organ failure in some patient. It is also one of the reason that some COVID-19 patients have loss limbs or appendages.
Please follow all supplement recommendations based on your laboratory studies and all COVID-19 recommendations. We would recommend frequent hand washing, surface cleaning, social distancing, and wearing face masks as the most basic precautions and increase precautions based on your health status.
