Billroth I or II and Diabetes

March 01, 2016 8:37 am

I have previously discussed the two variations  of anastomosis that can be created between the stomach and the first segment of the small bowel. Historically, Billroth I and II procedures were named after Dr. Theodor Billroth who did the first of this type of operation in the 1881 (BI) and then in 1885 (BII).

The following article  published in Bariatric Times 2016;13(2);8-10.  discusses the resolution of diabetes and its outcomes based on these two types of the anastomosis  between the stomach and the small bowel.

Billroth I VS Billroth II

This study concludes that  “In summary, we concluded that based on our analysis of the literature, BII reconstruction is more effective than BI reconstruction for achieving postoperative diabetes control.”

Lets remind ourselves that Duodenal switch is a BII reconstruction where as the SIPS, SADI and other lookalikes are BI.

This study only reiterates that these unproven operations need to be studies further and that the patients need to be aware of the consequences of their decisions when choosing a particular operation. Be aware and informed to know the differences between Duodenal Switch and the procedures that are promoted as similar one – which they are not.

Hiatal Hernia Treatment

February 13, 2016 4:45 pm

Hiatal Hernia may be one reason for developing symptoms of GERD (Gastroesophageal reflux disease). As we have discussed previously, the treatment for reflux should not be long-term use of the “purple pill”, or all PPI’s, as advertised on TV. There is a large population who are delaying  definitive care and probably increasing their chance of esophageal cancer by taming the  symptoms of the reflux with over the counter or prescription medication.  However, it is important to note that taming the symptoms isn’t necessarily stopping the effects. Be proactive and request to be sent to a surgeon to fix any issues if you are being recommended to “….take the medication and come back again for another endoscopy  again ….”

Types of Hiatal Hernia:

Hiatus Hernia Types

This is an example of a patient who had  been told to take the medication and just keep and eye on it with repetitive endoscopies.  He had to have hiatal hernia repair with  Nissen fundoplication for progressively worsening symptoms even on maximum treatment.

This is another example of a hiatal hernia repair procedure  of a patient with a previous history of sleeve gastrectomy.  In this patient, mesh had to be placed in order to fix the hiatal hernia.

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!

Fluids and Electrolytes After Weight Loss Surgery

January 29, 2016 7:06 am

Fluids and Electrolytes after weight loss surgery are an important part of recovery and lifestyle after undergoing a weight loss surgical procedure. Potassium is an important electrolyte found in higher concentrations within the fluid of the cells. It is important in muscle contraction, heart rhythm, nerve function and co-enzyme function.

Fluids and Electrolytes

The following webinar (link) discusses the balance of fluids and electrolytes with particular attention to post weight loss surgery concerns. Deficiencies can cause heart arrhythmias, muscle weakness and cramping, intestinal paralysis, and neurological deficits.

2015 ASMBS Summary

November 11, 2015 7:31 am

The 2015 ASMBS meeting was held November 2-6, 2015.  It was combined with TOS (The Obesity Society) and had more than 5,600 attendees from all over the world in every aspect of obesity treatment.  There were some interesting additions and deletions from this meeting compared to the past.

The one sentence that comes to my mind is “I told you so”.

One important addition was a DS course for Surgeons and Allied Health.  This was very exciting, except the content and questions seemed to gravitate to  SADI/SIPS/Loop rather than DS.  Dr. Cottam was one of the moderators of the course.  It seems that they have found the value in preserving the pyloric valve. It was clear that the discussion was driven by the need to come legitimize the single anastomosis procedures at this early stage with almost no data to prove long term outcome. With many of the Vertical Sleeve Gastrectomies having re-gain and the they are looking for a surgery that the “masses” can perform. This was actually the term used by one of the presenters, implying that the duodenal switch needed to be simplified so that all surgeons, those who have pushed all other procedures can not offer Duodenal Switch to their patients with less than desirable outcome.   Several surgeons also voiced their concern and dissatisfaction with the issues and complication of the RNY and want an alternative.  There was much discussion regarding SADI/SIPS/Loop being investigational and that it shouldn’t be as it is a Sleeve Gastrectomy with a Billroth II.  Dr. Roslin and Dr. Cottam discussed their SIPS nomenclature saying they wanted to stay away from something that had Ileostomy, suggesting bowel issues, or the word “SAD”i  due to negative connotations. The point to be made is that the SADI and SIPS and the loop are all the same.  I have also noticed other surgeons using SADS (Single Anastomosis Duodenal Switch).  There is a great deal of industry behind these procedures and many surgeons being trained in courses funded by industry. One surgeon stood up and informed the entire course that they need to be clear with their patients about the surgery they are performing, as he had been in Bariatric chat rooms and there is upset within the community about SADI/SIPS/Loop being toted as “the same or similar to Duodenal Switch”.

There was also presenter who said “We are doing something new about every five years.” No,  “we” are not. Some of us have stood by the surgery and techniques with the best long term outcomes and not gone with every “new” thing out there. The process of  Duodenal Switch may have changes, open Vs. Lap, drains, location of incisions, post operative care and stay, but the tested procedure with the best outcome has been the duodenal switch operation and not the shortcut versions. Although, those of us that are standing by long term results seems to be in the minority. Why do I stand by Duodenal Switch?  Because it works, when done correctly by making the length of the bowel proportional to the patient total bowel length, and height, and not just cookie cutter length for all patients,  with the right follow-up, patient education, vitamin and mineral regime and eating habits.

A new addition was the Gastric Balloon, which in the research presented had a 60-70% re-gain rate and a no more than 10-15% weight loss one year only. This data represents more than 70% weight regain when the balloon is taken out.  The Gastric Balloons can be left in between 4-6 months depending on the brand or type of balloon. The Gastric Balloon is not new to the Bariatrics and was first introduced in 1985. After 20 years and 3,608 patients the results were  and average of 17.6% excess weight loss. It seems that we are re-gurgiating old procedures. There are many new medications that were front and center in this meeting.

The Adjustable Gastric Bands were missing from the exhibit hall this year. It is my hope and feeling from the other attendees that we may be seeing the era of the Adjustable Gastric Band being placed in patients come to an end.  Although there are some still holding out that there are some patients that can do well with the Band.

Attending the 2015 ASMBS meeting this year, as it has every year, only reemphasized the importance of avoiding what has become the norm of chasing a simple solution that is fashionable and easy now. We stay convinced that the duodenal switch operation with the common channel and the alimentary length measured as a percentage of the total length is by far the best procedure with the proven track record. The patient should avoid the temptation of settling for an unproven procedure or device, because if history holds true, there will be a need for revision surgeries in the future.

 

 

 

 

Bowel Length in Duodenal Switch

November 09, 2015 6:25 am

Malnutrition is one of the most feared complication of the duodenal switch operation. It may present years after surgery. What is common is a mix of nutritional deficiencies which include fat soluble vitamins, and protein calorie malnutrition. These all point to possible excessive shortening of the common channel. In my practice we have seen patients that have had lengthening of their common channel to improve their metabolic picture. What is very obvious to us, is that we see disproportionately higher number of cases coming to us for revision from practices where the common and alimentary lengths are done as a “standard” numbers with no specific adjustments made for the patient, their anatomy and situation. I have said for years, that the length of the bowel that is measured to be become the common and the alimentary limb should be a percentage of the total length of small bowel, rather than a pre-determined measurement. Here is a visual description of how this works.

If a common channel and the alimentary limb is measured to be a percent of the total length then the chance of protein calorie malnutrition is minimized since this will take into account the bowels absorptive capacity which is being reduced. This decrease in the absorption is done as a fraction of the total length.

Raines et al. published  a study in 2014, that showed how small bowel length is related more closely to a patient’s height and not weight.  And yet, some surgeons totally based the length of the common channel and the alimentary limb arbitrarily based on the patient pre operative BMI and nothing else. Could this be the cause of why I see some patients coming to us for revision of their duodenal switch for malnutrition?
