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.

Are Health Insurances working against you? Especially in people who have the disease of obesity? Insurance companies continue to lengthen the pre-operative period. The time that is required to lapse has now in some cases been extended between 6-12 months for some commercial health plans. There are yet again studies that have shown no benefit to the patient with this mandated waiting periods imposed on the patients. Unfortunately, the patients need to challenge the health care insurance companies by the means of all options that may be available to them. This may include internal appeal to external evaluation by some state agency. There are numerous studies that show pre-operative dieting does not equal better weight loss or compliance.
A Parathyroid scan or Sestamibi scan may be needed if the typical weight loss surgical reasons for elevated PTH levels have been addressed. Sestamibi is a small protein which is labeled with the radio-pharmaceutical technetium-99. This very mild and safe radioactive agent is injected into the veins of a patient with overactive parathyroid and is absorbed by the overactive parathyroid gland. If the parathyroid is normal it will not absorb the agent. The scan below shows the uptake of the agent.
Calcium, Vitamin D and Parathyroid hormone are routinely measured on yearly follow up for most post weight loss surgical (WLS) patients. Elevated parathyroid hormone (PTH) may be caused by Vitamin D deficiency or calcium deficiency (most common in post WLS) or by over active parathyroid gland(s). In the latter case, if one of the four glands is overactive then this is knows as a parathyroid Adenoma. If all 4 are over active and are secreting too much PTH, this is known as hyperplasia. Ultrasound of the neck, may identify an enraged parathyroid gland (adenoma) which is located behind the thyroid gland. Given the large area where the parathyroid gland may be located, additional tests are needed to not only identify the location of the gland(s) but also to distinguish between single gland (adenoma) or multiple glands (hyperplasia) cause for the elevated PTH. It is important to investigate all avenues and testing in parathyroid hormone elevation and in some cases, not to rely on one test for your diagnosis. It is also imperative that weight loss surgical patients take their supplements routinely and consistently and have their laboratory studies followed at least yearly.
One of the findings following Gastric Bypass is a Candy Cane Gastric Bypass. Nausea and vomiting , upper abdominal pain is a common complaint of patient who have had the Gastric Bypass RNY operation. This is in addition to the high incidence of patients who experience the complications of weight regain and or dumping syndrome.
Quite frequently the symptoms of nausea, vomiting and upper abdominal pain of a patient with history of gastric bypass is evaluated by a primary care, referred to a gastroenterologist. The “routine” work up recommended is X-ray of the abdomen, maybe contrast study (Ct scan or upper GI) and for sure and upper endoscopy. The result quite frequently reported as “…nothing wrong”.
A typical upper GI in a Candy Cane Gastric Bypass situation may look like this:
A common and underreported problem may be a Candy Cane finding. The “blind” end of the small bowel anastomosis is too long and this results in food settling in the hook of the candy cane. The symptoms of the nausea, vomiting and upper abdominal pain may be from the residual food and liquids that do not drain from this area.
Candy Cane Gastric Bypass finding
Candy Cane Gastric Bypass cases will require surgical intervention to shorten the length of the blind segment of the small bowel to improve symptoms.
It is my recommendations that any patient with history of weight loss surgery who is having any persistent gastrointestinal symptoms be evaluated by weight loss surgeon.
Liver is a vital organ. It has many roles in the physiologic pathways including protein productions, clotting function, iron metabolism, production of bile and cholesterol, etc. as well as metabolism and filtering of waste products. We should think of it as a refinery, for conversion of raw material from food to energy used by our body, in addition to a processing and distribution center for mineral, and nutrients. Liver injury can have devistating effects and long term ramifications if unchecked.
Liver is also very resilient and forgiving to stressors and injury. The liver will tolerate repeated insults caused by Medication (both prescription and over the counter) , obesity, Diabetes, alcohol, and herbal supplements, to name a few, but only if care is taken and the offending stressor is removed. During the injury phase, however, the liver may have a difficult time keeping up with bodily function needs due to loss of fully function cells.
The anatomy of liver can change from normal (both visually to the naked eye and under microscope) to mild inflammation and reverse back to normal if the underlying causes of injury are removed. IF, however, the anatomy of the liver changes with fibrosis, it crosses to an irreversible range where it can only be prevented from progressing rather than reversing.
In the obese population, Non-alcoholic Fatty Liver Disease (NAFLD) causes inflammation and a slow diminishing functionality of the liver. NAFLD is the leading cause of liver disease in the U.S. Unchecked or untreated NAFLD can progress to NASH (Non-Alcoholic Steatohepatitis. NAFLD or “fatty” liver disease is an accumulation of fat within the liver. NASH is a progression that can lead to inflammation of the liver cells or advance to fibrosis and cirrhosis. In addition to liver injury, there is some evidence that NAFLD also correlates with cardiovascular disease.
Causes of NAFLD:
- Type 2 Diabetes Mellitus
- High cholesterol
- Sedentary lifestyle
Symptoms may include fatigue, right upper quadrant pain, liver enzyme elevation
During bariatric or weight loss surgery we visualize and occasionally biopsy the liver to define the degree of injury, if identified. Following weight loss surgical procedure a rise in liver function enzymes may be expected due to the processing of waste products following fat mass loss. However, long term bariatric procedures can significantly improve NAFLD and NASH. Bariatric procedure require the adherence to protein and supplement requirements as well as regular physician visits.

Join our 2018 Back on Track challenge and let’s get back on track for 2018! The holidays were wonderful but if you find yourself with a few extra souvenirs don’t feel alone. The average American gains between 1-8 pounds during the holiday season and I am no exception. Let’s get back on track 2018 together.
Time to clear out the kitchen! Disposing of temptations and high trigger foods is the first step to getting back on track. Throw it all away and don’t allow them back in. If foods are difficult to acquired then they are less likely to be consumed.
Stock up on high protein and whole, unprocessed foods that are low carbohydrate and nutrient dense. When quality foods are easily available we are more likely to stay on track with the types of foods we should be eating. Simple sugars/carbohydrates are the biggest culprit of holiday weight gain. We need to go back to the basics of hydration, high protein, low carbohydrate/sugar, vitamin/mineral supplements and exercise. Simple sugars and carbohydrates are easy for our bodies to use and absorb. Cutting them out can jump start your weight loss. Each individual needs to identify the daily carbohydrate intake that works for them. Some people stay under 50 grams of carbohydrates daily and some can tolerate more daily grams. You may also need to look at your protein and fat intake. All excess nutrients absorbed have the potential to turn into fat mass and inhibit weight loss. Metabolism video.
Hydration is an important ways to start getting back on track. Water is essential to life functions. The brain is 85% water, blood is 80% and muscle is about 70% water. Hydration aids in digestion, eliminating waste, byproducts and toxins. It also can decrease the feeling of hunger. Lack of hydration can increase fatigue which can lead to craving high carbohydrate foods to increase energy.
Protein’s importance in almost every bodily function and muscle mass can not be ignored. High quality complete Protein sustains muscle mass during weight loss, aids immunity, antioxidant function, and enhances leptin and insulin function. Filling up on protein first will help with carbohydrate carvings and give a sustained satisfied feeling. A prior blog post gives additional information on the importance of protein and the effects of protein malnutrition. WLS makes daily protein intake important but especially after Duodenal Switch, protein is a necessity of daily life.
Vitamins, minerals and supplements will ensure the body has the nutrients it needs to function adequately and can keep cravings at bay. Deficiencies in vitamins and minerals can cause cravings for foods. Vitamin and minerals are essential to muscle function, red blood cell production, bone health, and numerous other physiologic functions. We may all slack off on our supplements occasionally but now is the time to get back into the habit of daily vitamins and mineral supplements. A daily vitamin, mineral, and supplement routine is a lifetime commitment after Duodenal Switch or any WLS. Here is a list of commonly used supplements. If you haven’t kept up with your minimum yearly laboratory studies, now is the time to be seen and have your labs done.
Exercise can increase weight loss, overall well being, mental well being, mood, alertness, improve digestion, improve sleep, and increases energy levels. Exercise does not have to be a daunting task. Simply adding 15-30 minutes of activity can give added benefits. Yoga, walking, dancing, lifting weights, hiking, and sports activities can be included or added to more traditional forms of exercise. There are many free online videos for all types of exercise available. This year we are teamed up with The Kinesis Centre to offer a 4 week training program that can be accessed from anywhere. A 4 week training program will be included in our 2018 Back On Track Grand prize.
Finding a new hobby can keep both your hands and mind busy, curbing the unconscious eating of foods that are high in sugar and carbohydrates. Adult coloring books, drawing, painting, knitting, crocheting, sewing, dance lessons, gardening, learning to play an instrument and many others are great ways to use your time and expand your quality of life and brain function. New hobbies can also help establish new coping skills. Our previous post on Coping Skills After Bariatric Surgery can be found here. There are a whole host of online videos for “how to” on new hobbies.
Teaming up with others can also help increase weight loss and compliance. Support from friends, family and other groups will assist you. There is a whole gamut of support group online and in person. If you have fallen out of the habit of attending our support group or webinars get back to them. You can find our schedule and announcements regarding webinars here. Our Central Valley Bariatric Facebook page also gives daily inspirational messages, protein recipes and articles and any new information or research available. There is also our Duodenal Switch Facebook Group. Anything that increases accountability is a benefit and motivates us to stay on track.
Experiment with new recipes and flavors that are bariatric friendly and within your dietary needs. There are so many options for quick and easy meals that are whole foods, high protein, and low carbohydrate. We have several recipes on our page for all stages following weight loss surgery and Duodenal Switch. However, there are endless option on the internet in Paleo, low carb, and high protein type recipes.
In the spirit of new starts and getting back on track 2018, we are having a giveaway with the basics to get back into the swing of things. This year we are looking for before and after weight loss surgical journeys for our Grand Prize. Share your weight loss journey!

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.
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.)
Further information on revision from failed AGB to Duodenal Switch or other failed weight loss surgeries can be found here.
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.
We’ve created a helpful map and parking diagram for our new Pasadena, CA office location. It also has a general layout of the Huntington Memorial Hospital Campus and Pre-operative intake and testing area. We hope that you find it helpful on your next visit to see Dr. Ara Keshishian, General and Bariatric Surgeon.
Dr. Ara Keshishian has performed more than 2,000 Duodenal Switch procedures, thousands of Sleeve Gastrectomies and more than 500 revisions from other Weight Loss Surgeries such as RNY Gastric Bypass, Adjustable Gastric Band, and Sleeve Gastrectomy to Duodenal Switch as well as General Surgical cases over the last 18 years of private practice.
Whenever you are dealing with insurance issues it is important to have a general understanding of insurance ins and outs. The Obesity Action Coalition has a good general guide to the insurance process here. If you are having issues with out of network, out of area, or insurance appeals and denials for Duodenal Switch, there may be some additional assistance from two individuals who have had the Duodenal Switch procedure themselves. We are grateful that they have provided assistance throughout the years to the Duodenal Switch community. The following is their statement on insurance.
The majority of insurance companies are in the business of making money (for profit). They can deny requests for preauthorization with impunity. These denials are often complexly worded and difficult to comply with and overcome, and are definitely overwhelming to the patient, and the busy surgeon’s office. The vast majority of patients faced with demanding if not impossible to achieve prerequisites, or denial of the request for preauthorization simply give up, and the insurance companies pocket the savings.
If you find yourself facing impossible pre-op hurdles, or a denial, we urge you to appeal, and to seek assistance in preparing the appeal. You can hire an attorney, of course, but there is an informal and free resource we suggest that you investigate as well.
If you go to BariatricFacts.org (a non-profit, patient-run site), you will find individuals who are long-term DS postops, and patient advocates. They have been helping patients, pro bono (for free), for over 10 years. They will help you draft your appeal letters, provide supporting medical and legal documentation, and prepare draft letters of medical necessity to be reviewed and signed by your surgeon supporting your appeal. They will not represent you directly, but they will help you best represent yourself. in many cases it is necessary to exhaust all internal appeals (because the insurance companies are unlikely to overrule themselves), and then file for external review, where independent reviewers often overrule improper denials. If you join and then post on BariatricFacts.org asking for help, you will be connected with them and you can decide if you want their help.
Please note that this is just a suggestion. It is neither legal nor medical advice, nor a guaranty regarding their services, and you should always consider getting legal advice and assistance from an attorney who will represent you directly. The members at BariatricsFacts.org will help you draft your own letters, but will not be your legal or medical representatives; you will be required to do a fair amount of your own work on your appeals, and to sign them yourself.
It is suggested that before or at the same time as you contact the resources suggested at the site, you gather as much of the following information as you can:
- A copy of your Evidence of Coverage, which is the usually 100+ page insurance contract between your employer and the insurance company, which you can obtain it from your HR department. If you are self-insured, it will be available directly from your insurance company. Note: it is NOT the Summary of Benefits – it needs to be the contract itself.
- If your insurance is through an employer, you need to determine whether your plan is self-funded or fully-funded. Your rights are significantly different under the two types of plans.
- If your insurance company has a separate bariatric surgery policy, provide a copy of that, too.
- A copy of your surgeon’s request for preauthorization, which provides the ICD-10 and CPT codes submitted.
- A copy of your denial letter, including the section regarding your appeal rights.
* It is strongly recommended that you obtain a copy of your surgeon’s LOMN (letter of medical necessity) before it is submitted to your insurer or for external review, so we can assist your busy surgeon in making the strongest possible case for you.
Don’t be deterred by a denial. It is unfortunately more common than it should be, but it can often be overcome if you meet the requirements for bariatric surgery, if you get help navigating the process.
