Calcium Lab Results

June 05, 2018 3:26 pm

Calcium is measured to evaluate function and adequacy of a physiologic processes. Calcium plays a critical role in several body functions such as, coagulation pathways, bone health, nerve conduction, and other functions. It is important whenever you are evaluating laboratory results that you look at the whole picture of the person, including medications, other laboratory studies and health history. One value is not a stand alone result. There are many factors that effect calcium results.

Factors that effect calcium results: (not an all inclusive list)

pH

Albumin

Lactate

Heparin

Vitamin D deficiency

Magnesium depletion

Anticonvulsants

Renal Disease

Pancreatitis

Parathyroid

Thyroid

The two most common issues following Weight loss Surgery or Duodenal Switch may be albumin level and Vitamin D level. Please see past blogs on Vitamin D. Magnesium may also play a role in a Duodenal Switch patient.

The most common calcium result drawn is the total calcium level. Laboratory results may not explicitly label it as such, however, it measures the calcium that is bound to protein. Ionized calcium is the free calcium that is representative of the true total calcium. Ionized Calcium can be measured by ordering specific lab. Alternatively, the Ionized calcium can be calculated by the following formula: Corrected calcium mg/dL = (0.8 * (Normal Albumin – Pt’s Albumin)) + Serum Ca ) or use the calculator at the bottom of this post.

The low Albumin level accounts for the low calcium level. This may be the reason for a patient with a low albumin/protein level, also having their calcium level reported as low. However, when adjusted for the protein deficiency the corrected calcium comes into normal range. Video of Trouseau’s sign of a patient with calcium deficiency.

The first step in a patient who has low calcium reported, is to make sure their protein and albumin levels are normal, along with Vitamin D.

Calcium levels are managed by two processes major regularly hormones and influencing hormones. Controlling or major regulatory hormones include PTH, calcitonin, and vitamin D. In the kidney, vitamin D and PTH stimulate the activity of the epithelial calcium channel and the calcium-binding protein (ie, calbindin) to increase calcium absorption. Influencing hormones include thyroid hormones, growth hormone, and adrenal and gonadal steroids.

Lymphatic Channels

May 22, 2018 8:21 am

We are all aware of the arterial and venous systems. Arteries take the oxygenated blood from the heart to the organs and the veins take the blood back to the lungs to unload the carbon dioxide and reload oxygen to be taken back to the organs. In addition to the arterial and venous vascular systems, we also have the lymphatic channels that flow into the lymphatic system.

The Lymphatic channels and system may be new to some, however, it is the third vascular network that is much less defined. The Lymphatic system collects fluids that has left the artierial/venous vascular system along their travel outlined above and take it back to the venous system. The lymphatic vessels transport this fluid to the lymph nodes throughout the body where the nodes filter the fluid of bacteria and harmful substances. Eventually, the fluid makes it way back to the venous system via the Superior Vena Cava. Additionally, Lymphatics collect the lipids within the GI tract and transport them to the venous system for metabolism. Most of the time these serosal lymphatic vessels are very small and hard to notice on the bowel.

Example of Lymphatic channels

The following image is in a patient who had small bowel obstruction. The obstruction had resulted in vascular congestion at the base of the mesentery. The congestion had effected the low pressure system of the veins and the lymphatics disproportionately more that the arterial system. The white-milky tubular structures are the lymphatic channels filled with lipids.

Visible white lymphatic channels

There are three layers to the small intestinal lymphatic system, in the villi, submucosal and serosal layers and has the unique ability to transport absorbed intra-lumenal nutrients. There is a need for further research in the areas of health, obesity and disease in regards to the lymphatic system.

Compounding Pharmacies

January 22, 2018 2:38 pm

New FDA regulations for compounding pharmacies has spurred changes in our pricing and ability to provide injectable Vitamin A and Vitamin D.  The compounding pharmacies are no longer compounding injectable Vitamin A and there is a nationwide shortage of the national brand of injectable Vitamin A.  We have a tentative date of February 2018 when we may be able to obtain injectable Vitamin A. We won’t be able to quote pricing on Vitamin A injections until we are able to orders.

We are able to obtain and supply our patients with injectable Vitamin D but with a price increase.

The following is the letter we received from our compounding pharmacy.

“The healthcare industry has continuously undergone changes in regulations and legislation. The compounding industry is no exception and has faced rigorous regulatory requirements this past year such as new testing specifications and compliance standards.

We are set on facing these demanding challenges by meeting and exceeding these new regulatory requirements. We want to assure you we will continue to provide the best products on the market for you and your patients. Quality and safety remain a top priority. We understand that our pharmacy plays a vital role in providing care to your patients. The increase in pricing is a reflection of the additional cost in producing and testing the product based on regulatory specifications.”

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.

Long-term_AGB_outcome-791x1024

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.)

Bile Reflux Gastritis

January 10, 2018 1:45 pm

Bile reflux gastritis has been recognized as a significant cause of dyspepsia in a subset of patients. This patient group set does not respond to the standard treatment (not expected to) and some get improvement with the treatment of H.Pylori infection if one is diagnosed at the time of upper endoscopy and biopsy.

Inflammation and Foveolar hyperplasia are some of the findings that can be seen endoscopically. This and other findings have all been documented in the literature. An article published in 2005, reported over 40% incidence of Foveolar hyperplasia in patient with bile relax.

It is been noted that bile causes the thickening of the mucosa lining of the GI track. This is called Foveolar hyperplasia when the mucosa of the stomach is noted to be thicker with more numerous and deeper folds.

Foveolar Hyperplasia- Bile Reflux Gastritis

The treatment for this is reduction and prevention of bile reflux to the stomach, in some cases this can only achieved by surgical diversion of the bile from the stomach. Additional information on Bile Reflux and the surgical treatment can be found here.

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.

Insurance Appeals And Denials

August 07, 2017 7:08 am

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.
