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

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.

Cystic Duct & Common Bile Ductgallbladder duct anatomy

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.

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.

Inadequate Weight loss and Weight Regain

May 24, 2016 7:56 am

There were numerous causes for the inadequate weight loss and or weight regain after weight loss surgery.

These factors may include:
1-Type of the surgery: Duodenal Switch, RNY, Adjustable Gastric Banding, Intragastric Balloon, etc.
2-Patients metabolic state (age, activity level, hormones state etc)
3-Co-morbidities
4-Patient compliance
5-Other

Each and every one of these may be an independent factor or may be a contributing cause.

In our experience, patients non-compliance is not as common as others believe. Frequently, we see patients in our office where they have been told that the poor outcome of the surgery is “their fault”
We see this with RNY, and Band patients as well as some of the duodenal switch patients who are seeking advice for weight regain or inadequate weight loss.

I would like to talk about the issues of inadequate weight loss or regain post Duodenal Switch specifically. Duodenal switch operation as described by Dr. Hess, outlined the division of the small bowel lengths to be proportional to each and every patients own total bowel lengths. This meant that two patients with the same BMI and weight will end up with two different lengths for common and alimentary limbs if there total length of the bowel is different. Unfortunately, too often patients are given a “standard”  or “set” ( not clear what that word means, since there is no established standard in the literature) length for common channels and alimentary  channels regardless of the total small bowel length. In some patients, those lengths may result in acceptable weight loss. However, quite frequently a patient with a preselected length for the common and alimentary limbs will end up either loosing too much weight and have nutritional problems or not loose adequate weight. As with all practices, we have over the years had patients who have had nutritional deficiencies and excessive weight loss or have had inadequate weight loss. Looking at the raw numbers however, we have had more patient from other practices that have come to us for revisions and corrections of lengths of the bowel lengths from other practices that our own patients have required.

Another level of the confusion is the improper interchanging of the “SIPS and SADI” procedures with the duodenal switch operation. As I have said in the past repeatedly, SIPS and SAID are not the same as the duodenal switch- and attempt to call these different procedures the same is misleading to say the least.

The other category of weight regain or inadequate weight loss includes medications and new health issues.  Discussed in a previous blog, there are many medications that can influence weight gain.  It is important to work with your health care provider to find medications that have a positive effect on symptoms without added side effects whenever possible.

In summary, weight re-gain or inadequate weight loss can have many facets.  However, surgical technique can provide an advantage.  Each aspect should be addressed and identified.

Dual Testimonial: Cameron’s Gastroparesis surgery & Scott’s Revision of a Duodenal Switch

February 01, 2016 8:04 am

In 2015, I came into contact with the most unique, passionate, urgently responsive; talented beyond belief and caring surgeon I have ever met. Our oldest son who is a 21-year-old cancer survivor, has had nearly five years of medical nightmare as diagnosed with severe gastroparesis resultant from his vagal nerve being severed during a previous Nissen Fundoplication surgery. We didn’t find out that this had happened until nearly two years later and only after a 4 hour gastric emptying test showed that Cameron’s stomach was only about 30% emptied after four hours (should be empty after an hour) due to gastroparesis.

I had heard about Dr. Keshishian on a Bariatric support group page on which I post and get great advice.   The surgeon back in Central, IL where we live told us that Cameron needed a subtotal gastrectomy to remove 80% of his stomach! This sounded radical and no way in the world was that going to happen. I was given Dr. Keshishian’s email address so I could consult with him for his advice. It was a Saturday morning around 7 AM Central time when I sent off an email to Dr. Keshishian detailing Cameron’s medical history and current issues. I was in hoping that his office would get the email on Monday and hopefully get back to me within a week. I went out to my kitchen to get a cup of coffee and when I returned I had a missed call with a California area code. Yep, it was Dr. Keshishian. I called back and we talked for 45 minutes.   He suggested several things and told me that any good general surgeon in my area could do surgery on Cameron and fix him, well that was the only time he was wrong. We couldn’t find anyone in our area who would do the surgery.

So we talked and agreed that Cameron needed a Roux-en Y drain put in place to physically drain his stomach by way of gravity (not for any weight loss as very little small bowel was bypassed). Dr. Keshishian got us in the next week and we flew out to Glendale where he met with Cameron for an examination on that Monday.   On Tuesday, Dr. Keshishian performed surgery to fix Cameron’s herniated diaphragm, loose Nissen wrap, performed the Roux-n Y limb and anastomosis to the stomach.  Dr. Keshishian also found a Meckel’s diverticulum (a congenital small bowel defect that can cause internal bleeding and serious issues). The following Sunday, Cameron developed severe pain due to chronic pain from his Cancer treatment and 12 subsequent surgeries, many on his abdomen. Dr. Keshishian saw Cameron in the ER and  spent 3 hours fixing Cameron’s pain issue and making sure he was medically sound so we could fly home the next day.

Today, Cameron has very little to no issues  which you wouldn’t have believed possible six months earlier. In the past, he had violent retching, dry heaving and bad nausea daily which had him severely incapacitated and very depressed due to a feeling of hopelessness and pain from the Gastroparesis. He didn’t believe he had a chance at a normal life but Dr. Keshishian gave Cameron his life back. We are eternally grateful for your huge heart and talent Dr. Keshishian. Thank you!

During our time in Glendale in 2015 for Cameron’s surgery Dr. Keshishian and I began discussing my situation. I had been given a virgin Duodenal Switch performed by a surgeon in Illinois in September of 2013. A year later in 2014 and 180 lbs lighter, I ended up in the hospital as I was passing out. I had a resting heart rate of 35 BPM, a blood pressure in the 75/40 range and incredibly bad labs including anemia, low copper, low zinc, and dangerously low albumin and total protein. A full cardiac work up was completed and I spent a week in intermediate care. Why? I was extremely malnourished even though I was consuming 200-250 grams of protein daily!   Why was I malnourished? Because my original surgeon performed a “cookie cutter DS” on me where he didn’t measure my small bowel and arbitrarily gave this 6’2 man a 100 cm common channel and a 150 cm Alimentary limb. Way too short on the AL!  Had the Hess method been followed (the only way the DS should be allowed to be completed) my CC would have been 100 cm (that was okay) but my Alimentary channel should have been 275 cm!   Simply put, my absorbing portion of small bowel was 34% and the Biliopancreatic limb (non-absorbing) was 66%. It should have been a 50/50 ratio with 100 cm CC, 275 cm AL and a 375 cm BPL. In order to combat my severe malnutrition that September of 2014 I went on a pancreatic enzyme (CREON) to assist my nutrient absorption.   I was taking with meals right around 400,000 IU’s of CREON (a boat load) and this was barely keeping my nutrients in range and lab values barely in range. After speaking with Dr. Keshishian, he recommended that I give it until around September of 2015 to see if my absorption increased enough to where a revision wouldn’t be required. Towards the end of July, I all of the sudden lost nearly 20 pounds in two weeks from my already frail and scrawny body. I saw my surgeon in Peoria as I was very alarmed; and I had been having bad cramping and other issues point to a possible bowel obstruction   His exact words to me were “see me in 30 days, you are like the DS poster boy of good nutrition”. As you can imagine I found that completely unacceptable and soon as I was out of that appointment I emailed Dr. Keshishian. He told me that if I couldn’t get a revision ASAP I would need to immediately go on TPN. Two weeks later my wife and I landed at LAX and were in Glendale on Monday morning for an exam with Dr. Keshishian.

The job Dr. Keshishian did describing what he was going to do, and of course this was a visual presentation with Dr. Keshishian drawing (you know Dr K’s love of drawing) out for us what he was going to do. He thoroughly explained for my wife and I so she was comfortable with what was going to happen and we fully understood what he was going to do. Doc also found an umbilical hernia that he was going to repair and I had an anal fissure as well that wouldn’t heal so we discussed what he would do to examine and possibly fix during my revision surgery. The next day Dr. Keshishian performed surgery where he fixed the umbilical hernia, measured my total small bowel length to determine appropriate channel lengths and found an repaired a huge mesenteric defect (intestinal hernia and Dr K has a picture of my guts with the huge hole in the mesentery that he has posted on his blog discussing intestinal hernias and blockages), fixed my fissure (Thank you!) and put in a side by side anastomosis that effectively lengthened my AL by 125 cm and my CC by 25 cm worth of absorption. This put my absorbing intestine to BPL ratio where it should have been in the first place (50/50 ratio).

I am pleased to say that I immediately went off the CREON and my absorption and subsequently my lab values improved tremendously. At surgery on August 18, 2015 I weighed a whopping 170 lbs. Today I am weighing in at 183 pounds and well on my way to Dr. Keshishian’s suggested optimal weight target of 205.

Dr. Keshishian is absolutely amazing and the best in the world when it comes to performing the Duodenal Switch and revision to DS Surgery (Band to DS, RnY to DS, Channel extending revision to DS).   I would recommend Dr. Keshishian to any patient who needs a virgin Duodenal Switch to get their health back and especially to those who were sold a garbage RnY or Crapband procedure that ultimately failed you (it failed you, you did not fail). In fact, I am trying very hard to convince my brother and Step Mother to fly to Glendale and have Dr. Keshishian perform a Duodenal Switch on them. They very much need it for their health and Dr. Keshishian is the best in the world having performed over 2,000 DS procedures.

I don’t say this lightly. Ara, you are one of the finest human beings I have ever had the good fortune of knowing and your surgical skills are second to none.   I really do admire and love this gentleman like a brother and consider him to be a friend. Thank you for using your incredible skill to fix my health issues resultant from the failed cookie cutter Duodenal Switch I was given two years earlier by another surgeon.  Had I met you back then and knew what I know now, you would have performed my virgin DS and I would not have suffered for two plus years. Thank you from the bottom of my heart, Dr. K!

Revision of a Sleeve Gastrectomy or RNY

August 31, 2015 6:32 am

These are examples of two types of patients referred to us for revision surgery. The first example is a  gastric bypass that we revise to the duodenal switch operation. The upper GI series after the revision, shows a “banana shaped” stomach, the pyloric valve and the duodo-ilesotomy anatomosis component of the duodenal switch.

  The second example, images noted below,  is that of a sleeve revised to the duodenal switch – both operations done at different institution. Note how the stomach is not a “banana shaped” and more like a funnel with a narrowing at the bottom of the stomach- a stricture.

Gastro-gastric fistula after gastric bypass operation

May 10, 2013 9:09 pm

One of the complications of gastric bypass is a gastro gastric fistula. This happens when a connection between the gastric bypass pouch develops to the remnant stomach. In a gastric bypass operation, a very small pouch is created from the stomach, and connected to a segment of the small bowel.
 
The purpose of this operation is to decrease over 95% of the volume of the stomach. In theory, the benefits of this is to reduce the volume of food that can be consumed.  Over time, the size of the stomach pouch, and/or size of the gastro-jejunostomy anastomosis  might stretch. This result in weight regain that is very commonly seen in about 3 years after a gastric bypass operation.
Another possible explanation for weight regain may be an abnormal connection that may develop over time between the bypassed stomach and the small pouch that was created. This abnormal connection is known as a gastro-gastric fistula. In a patient who may have a gastro-gastric fistula, the food can travel down the gastric bypass path or enter the bypassed stomach and go down the path of a normal anatomy. 
In these cases, the physiological effect of a gastric bypass procedure becomes  ineffective. The treatment that I favor most for correcting the complication of the gastro-gastric fistula is is to revise the gastric bypass to the duodenal switch operation.

Slipped Band

November 02, 2012 10:40 pm

“Slipped band” is actually a misnomer. It suggests that the band “slips” over part of the stomach, which is actually incorrect. In most cases, the band itself is scarred down to the surrounding tissue, as the stomach above and below the band is what migrates. This results in the stomach being partially trapped above or below the band, which causes nausea, vomiting, and abdominal pain. If it is not urgently treated, it may cause erosion and perforation of the trapped stomach tissue.
The treatment may be as simple as completely removing the fluid in the band, which may allow the stomach to return to its proper place. Though in my experience, the majority of the cases require a surgical intervention and removal of the band.
