Adhesions, Internal Hernia And Bowel Obstruction

December 15, 2018 2:35 pm

Adhesions are fibrous bands of scar tissue that form during the healing process. Following surgery, many people live normally with this scar tissue. However, they are also the cause of bowel obstruction when the adhesions form in such a way that causes a segment of the bowel to either get trapped, or form a “knot”. In both of those cases, the end result is a partial narrowing or a complete blockage of the intestines. This is called bowel obstruction.

Without treatment, the blocked parts of the intestine can die, leading to serious issues. However, with prompt medical care, intestinal obstruction often can be successfully treated.

Other causes of bowel obstruction:

  • In children, the most common cause of intestinal obstruction is telescoping of the intestine (intussusception).
  • Intussusception telescoping of the interstine
  • Hernias — portions of intestine that protrude into another part of your body
  • Inflammatory bowel diseases, such as Crohn’s disease
  • Diverticulitis — a condition in which small, bulging pouches (diverticula) in the digestive tract become inflamed or infected
  • Twisting of the colon (volvulus)
  • Impacted feces
  • Colon Cancer

Internal Hernia

In patients who haven’t Bariatric / weight loss surgery or an untouched GI track, bowel obstruction may manifest itself by symptoms of loss of appetite, constipation, nausea, vomiting, enlarged abdomen, abdominal pain, cramping, with no passage of gas or bowel movements.

However, patients who have had a weight loss surgery (Duodenal Switch, or the Gastric Bypass) because of the parallel limbs of the small bowel, the symptoms outlined above may not present. The diagnosis of a bowel obstruction, when suspected, should be identified with CT scan of the abdomen and pelvis with Oral and IV contrast. A CT scan with no oral contrast or water instead of oral contrast is inadequate and may lead to a delay in diagnosis and surgical intervention. Examples of Bowel Obstruction CT findings were discussed previously.

The treatment for an internal hernia and adhesions causing a bowel obstruction depending on the severity may range from observation to  surgical intervention in order to release the small bowel from the constraints of the adhesions.

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.

Gallbladder, Duct and Duodenum
Gallbladder, Duct and Duodenum

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.

Health Insurances Working Against You

July 09, 2018 12:01 pm

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.

Parathyroid Scan

July 09, 2018 11:48 am

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.

Candy Cane Gastric Bypass – RNY

June 21, 2018 1:05 pm

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:

Anatomy_1
Upper GI

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 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.

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.

Calcium bound to albumin Keshishian

Duodenal Calcium Metabolism

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.

2018 Back on Track

January 28, 2018 11:38 am

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! Don’t be shy, your journey can inspire others and/or motivate yourself. To enter the Back on Track 2018 Giveaway, please submit your weight loss surgical journey with before and after pictures to contact@dssurgery.com or you can also post your before and after pictures on our Facebook page. You will also need to sign a release for the use of your story on our website. We will draw 2 names from those that enter by announcing it on our FaceBook page or by e-mail on February 14, 2018. You must submit your mailing information to contact@dssurgery.com in order to claim the prize. You must be a verifiable patient of Dr. Ara Keshishian.

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.”
