Afraid of Surgery..making decisions

on 5/12/12 3:20 am - Magnola, DE
Hello everyone!
    I am interested in having bypass surgery, but don't know much about it. My sister had the surgery 4 years ago and lost 200+ pounds. My am overweight also but could always lose 50 pounds on my own through diet and exercise. The problem is I always put it back on. I was never really that concerned about it until I was diagnosed with diabetes 2 years ago. Now I have numbing in my fingers quite a bit and I am also on blood pressure meds. I am now considering the surgery because I've read that its the only current "cure" for diabetes and I dont want to live on medication.

     What made you finally decide this decision was the right one? I am afraid of the unknown. This is major surgery but I think the benefits outweigh the risks. How long were you in pain? How long was your hospital stay? I have an 18 yr old senior and 15 year old junior so I will have some help as school is about to end. I also have a 4 yr old daughter and she still under mommy's feet all the time (shopping partner). My sister had some sort of infection in the first month so I her recovery wasn't that wonderful the first 6 weeks. I was interested in your thoughts, I think I have made up my mind, but need some more positive feedback. Also, how often do people die from the procedure?

I had my RNY in 2008. I will let the newer folks go over most of your concerns but I will let you know that I had open rny with a hospital stay of 2 days plus 1 xtra at my request just to alieviate my fears. I did not use any pain meds after surgery (not needed took 2 doses in hospital because nurses pushed the button but none after first 12 hours) I was muscle sore from moving muscles out of way of stomach, for about 2 weeks. I had zero complications, zero bad effects,the only way I knew I had the surgery was the weight loss and a new Lactose intorlerance. No dumping, No diareaha, My labs were always excellent with no changes needed. No new Maladays developed. In short Healthy as a Newborn. I only had help on the weekends but didn't have anyone to take care of either. Remember when you are gathering info on this proceedure that when you come across scary things you must remind yourself of the vast number of people who have had this surgery and do not post on this website because everything is fine. It is my belief that the scary things talked about on here can and do happen but they do not seem to be common in the sheer number of surgerys done. You should have faith and trust in your doctors, be vigilant to follow the guidelines, come here for support, and remember that most all of the things that might happen are managable.

Hello Muzzled!
     Thanks for you reply. Yours is the type of outcome I hope for when I have my surgery. Its amazing that you didn't even have to take pain meds after the first 12 hours! I will take your advise, do more research and have faith in the doctors I have chosen. Thanks so much!!

Keep in mind that Muzzled is looking into having her RNY revised.

Which is why Muzzled stated that the poster will need to follow the program presented by the surgeon.  Every surgery has a program.

True---but sometimes, the program just doesn't work. That's why revisions happen.



Hi, I’m Dr Mitchell Roslin, Chief of Bariatric Surgery at Lenox Hill Hospital in NY and Northern Westchester Hospital in Mt Kisco, NY.  The title of this talk is, “Revisions – Does the Patient Fail the Procedure or Does the Procedure Fail the Patient?"  This is a copy of a talk that I gave at the ASMBS in Orlando in 2011 and I was asked by many of the attendees at the session to see if  I could record the talk and place it online. 

The purpose of the talk is to try to explain some of the physiology behind bariatric procedures and weight regain or inadequate weight loss following bariatric surgery.


When I started doing bariatric surgery 17 years ago I really thought it was simple.  I thought when we did a gastric bypass what we did is that we made the stomach smaller so that people were forced to eat less.  Then we added an intestinal bypass so that some of what was eaten was passed into the fecal stream.  I now know that bariatric surgery is far more complex.  The stomach is far more than just a storage organ, it actually produces certain hormones that regulate hunger and satiety.  As a result I think concepts like restriction (making the stomach small) or malabsorption (bypassing part of the intestine) are rather simplistic and instead we need to think of bariatric surgery as gastric and intestinal.  What I’ve learned is that one of the major aspects of the gastric part of the operation is suppression of hunger, especially through  the reduction of the hormone gherlin.  In addition, instead of a malabsorptive component probably what the intestinal component of the operation does is it increases the work of digestion therefore increasing the metabolic rate.  



Frequently, patients who haven’t done well with the various bariatric procedures have been labeled as non compliant, or not following directions.  One of the things we have to realize is that if it were simple to follow eating directions nobody would have ever required bariatric surgery.  Another thing that we have to realize is that obesity is not a single disease.  Obesity occurs where there is inadequate regulation or inadequate balance between the amount of energy taken in and the amount of energy that is expended.  As a result, the defect can be anywhere in the process, so that any no two patients that we see may have the same defect, yet we all treat them similarly.  So when somebody doesn’t do well with an operation we tend to say that it’s because they haven’t followed the directions, or they’re noncompliant.  An alternative explanation is that the operation doesn’t change or alter the physiology that caused their obesity and is not effective in their particular case.  I think that if we’re going to take credit for bariatric surgery causing weight loss and being the most effective treatment of obesity, when patients regain weight the operation also has to be a part of the burden.  We have to realize that there may be a physiological reason for weight regain, not just behavioral changes and lack of compliance.  The purpose of this talk is to try to explain what we’ve seen in the two most common procedures performed in bariatric surgery – laparoscopic adjustable gastric banding and gastric bypass.


As mentioned, obesity occurs when there is any breakdown in the negative feedback system that controls energy balance.  Human energy intake is mainly controlled by hormonal factors   There are several key hormones that control hungry, satiety, as well as early energy and long term energy requirements.  Ghrelin which is produced primarily in the stomach is considered the hunger hormone.  PYY which is produced mainly in the intestine is considered the satiety or fullness hormone.  Insulin is the short term energy hormone and it works along with GLP.  Leptin is the long term energy hormone and is mainly produced in fat cells.  But even this is relatively simplistic and leptin and insulin actually complete sometimes for binding in the hypothalamus of the brain.  As a result a lot of patients who are insulin resistant also have excess leptin but leptin cant tell the brain that you already have too much fat tissue.  So there is a breakdown in that regulation.  As opposed to the input for energy intake which is mainly hormonal, the output is mainly through the nervous system.  When the body wants to conserve energy it increases the tone of the parasympathetic system, reducing the heart rate and the metabolic rate.  And this is what occurs when people try to reduce their caloric intake.  When the body wants to produce more energy it activates the sympathetic system.  The bottom line is that energy balance is a rather complex process and a deficit anywhere either in the input or the output or the afferent or efferent system or as well as in the brain or central nervous system and the hypothalamus can cause obesity because of the energy imbalance.  

**Video clip of Jassira, an OH'er talking about her LapBand and DS revision

After watching the previous video of the patient who struggled with the Lap Adjustable Gastric Band, and has done so well with the Duodenal Switch, it’s obvious that there different physiologic factors that occur following the bariatric surgical procedures  As mentioned the input for human energy intake is mainly hormonal.  Laparoscopic adjustable bands don’t reduce ghrelin or increase PYY thus its not surprising that a number of patients are still hungry following lap adjustible banding.  Thus instead of giving patients labels like noncompliant, or suggesting that the patient failed the operation because they didn’t work hard enough we need to understand the physiologic differences that our operations cause.   And in addition we need to begin to gain insight into why the particular patient is obese and what their particular deficit is in energy imbalance. Unfortunately we’re not able to do that at the present time and we continue to treat patients with these broad operations.  But it’s really important to realize that failing one bariatric procedure  doesn’t mean that you’re going to fail another bariatric procedure, and there is a lot more than just restriction and malabsorption.  The most important thing that we can offer our patients in bariatric surgery is hunger suppression.




While Lap Band appears to be an attractive alternative for many patients it also has many limitations.  The advantage of banding is the fact that the operation is relatively simple.  The complications and the risk of serious early complications are lower than other bariatric or stapling procedures.  The disadvantage of lap adjustable banding is the results are more variable and approximately 20-25% of patients, if not higher, will be dissatisfied with their weight loss.  A major reason is because that while can always increase the work of eating, making you chew more and eat slower, it frequently doesn’t make patients less hungry.  I often say a lapband is a diet with a seatbelt, and what I mean by this is that the band doesn’t affect ghrelin levels, doesn’t increase PYY hormone or PYY levels, and as a result really functions similar to a diet accompanied by a restrictive device.  Many patients do well with the band and patients who are most likely to do well are also those that are most likely to do reasonably well on a diet.  They’re younger, they’re more active, and they have lower BMI’s, or are in the lower part of the morbid obesity scale.  Patients that seem to do less well with LapBands include older patients, patients that have a BMI that approaches or above super morbid obesity, and there is now a suggestion from George Washington University that there may be ethnic differences, and African Americans seem to have lower overall weight loss as well as a higher failure rate.  Thus patients that are determining what bariatric procedure they want to undergo need to understand the probability that they have a higher chance of having inadequate weight loss with a Lapband or a realize band, as well as a higher chance of requiring reoperation and extraction of the band.  This is offset by a lower early serious complication rate.  But people have to understand that not all patients that have a Lapband have hunger suppression and in fact a significant amount never ever have any reduction in hunger, or for that matter, satiety.


Thus the major issue with Lap Adjustable Banding  is inadequate weight loss.  Another thing that frequently occurs s that we make the band tighter hoping to achieve restriction and force a smaller amount to be eaten and patients to be less hungry.  And what we’re successful in doing is creating a high pressure zone where patients don’t get hunger suppression and they continue to eat and we see dilation in the esophagus and changes in the motility of the esophagus itself.  So when you look at the Xray on the left side of this diagram you see tremendous dilatation of the esophagus above the level of the band.  When fluid is removed you can see that the esophagus becomes smaller and the band wide open but there are still these scalloping figures in the esophagus which is a signal of a motility disservice.   What you realize is that when you make the band tighter you make it harder to eat, you also make the esophagus work harder and you take the risk of having permanent motility disorders to the esophagus, but you don’t necessarily make patients less hungry.  The patient in this picture here actually came to me with the picture on the left because he started to regain weight because he was storing food in that large esophagus.  So it’s very, very important to understand the role of fills in Lap Adjustable Banding.   The role of fills is to create some level of restriction but if that pressure gets greater than what the esophagus can pump, then there can only be harmful side effects to the esophagus.  And just making bands tighter does not make all patients less hungry.  Frequently on the internet we see something called the Green Zone, which is a place where people who have bands eat less and are less hungry.  Unfortunately, on diagrams the Green Zone always exists, but clinically it’s often very, very difficult tot find a therapeutic window where patients eat less,  are less hungry, and where we don’t create a high pressure system that has an adverse effect on the esophagus.    


Whereas inadequate weight loss or extraction are the main problems of Lap Adjustable Banding, gastric bypass is an outstanding weight loss operation.  What I’m not convinced of is that it’s a great operation for the maintenance of weight loss.  An increasing problem in bariatric surgery is the number of gastric bypass patients that have regained weight 3-10 years following the operation.  We’ve done an awful lot of research on this topic and are beginning to form an understanding of why we believe this occurs.  Over the course of time what we see happening is food, or in this case contrast as shown in this diagram, passing immediately from the esophagus into the small gastric pouch, and then going straight into the intestines.  The food doesn’t remain in the pouch long because there is no restriction left between the gastric attachment and the intestinal bypass that was created.  As a result as soon as the patient eats the food goes into the intestine.  With this you get a rise in satiety factors followed by a rapid fall.  Thus what we believe happens following gastric bypass is there’s a return of inter-meal hunger so that when you actually question patients what you find is that while they can still eat less than they did prior to the operation but the problem is that they’re hungry one to two hours after eating.  If they eat foods that are higher in the glycemic index, or simple carbohyrdrates what happens is they have a very rapid insulin response followed by a low sugar, and this makes patients develop a maladaptive eating pattern. So what we are seeing is numerous patients with gastric bypass that have lost a considerable amount of weight, but approximately 30% of our post bypass patients we’re seeing regain a significant amount of the weight that was originally lost.  

Thus we believe the major problem in gastric bypass surgery is weight regain with a return of inter-meal hunger.  As a result it’s been our hypotheses that better bariatric procedures would have a valve at the end of the gastric pouch. And we believe that the best vale is the pyloric valve which is the normal valve of the stomach which controls emptying of food in the normal stomach.  There are two operations that now exist that allow us to preserve the pyloric valve.  They’re the Sleeve gastrectomy and the Duodenal Switch.  In order to test this hypothesis we have designed a prospective trial that we received grant for that examines the weight loss as well as response to glucose challenge in sleeve gastrectomy, gastric bypass, and duodenal switch. This is the first 6 month data from that perspective trial. And you can see that all of the operations cause effective weight loss, with duodenal switch causing the most weigh loss in the first six months.  


The purpose of the study though, was to compare the effects of a glucose challenge on the various operations that we perform.  This shows data when glucose is given both preoperatively, as well as 6 months following from surgery.  And what we do following the glucose challenge is we measure the insulin levels.  What we can see is a vast difference between the different operations.  With gastric bypass what happens at six months is that the insulin level goes down, but when challenged with glucose the insulin level actually goes up so high that it exceeds its preoperative value at six months. We don’t see this in sleeve gastrectomy and duodenal switch.  When you get such a rapid rise in insulin what happens next is a rapid fall in the sugar.  And we believe this rapid rise in insulin followed by the rapid reduction in sugar glucose level leads to inter-meal hunger.  Because we know when people become hypoglycemic in order to relieve the symptoms of the low sugar they become hungry and forced to eat.  So we believe what is happening in gastric bypass is that since there is no valve there’s rapid emptying and when there is rapid emptying there s rapid rise in the factors that determine fullness such as insulin as well as the other gut hormones, followed by a rapid fall. And when that rapid fall occurs patients become hungry.  What is really fascinating is that we don’t see the same response in duodenal switch which also has an intestinal bypass.


This diagram shows the 6 month results for insulin levels.  You can see that all the operations cause a reduction in fasting insulin level, which is very important and demonstrates an improvement in metabolic function.  However, gastric bypass causes a rapid rise when stimulated with glucose, much greater than sleeve gastrectomy or duodenal switch.  We believe that this rapid rise in insulin is a hallmark of a rapid emptying of food as well as the rapid distribution of nutrients to the intestine, and that this rapid emptying then leads to a rapid fall in glucose level and causes the inter-meal hunger that we think is responsible for a significant amount of weight regain following gastric bypass.


This diagram shows results that were determined in the RESTORE trial.  The RESTORE trial was the first multi-center trial to look at endoscopic treatment for weight regain following gastric bypass.  The idea was to try to reduce the anastomatic size so that patients could regain restriction.  Unfortunately to date none of the endoscopic trials have been shown to be effective to provide long term weight loss. There are some suggestions that short term weight loss could be achieved.  When we went back and looked at all of the data from patients that were eligible for the trial, and this means by definition that they have to have normal pouch following gastic bypass, no evidence of fistula, and an anastomatic size that was  >2CM, which we estimated approximately 70% of post bypass patients would have. We found that the most significant factor that would determine weight regain was the time from surgery.. Thus we felt that this was evident that the weight regain was physiologic, and was steady and progressive over time, especially in patients that have an anastomatic size >2CM.  When surgery is first done the anastomosis is made approximately 1.5CM, or slightly less. Unfortunately what we’re finding in time is that in time the anastomosis spreads to a greater size.  What we found looking at the data from the RESTORE trial is that once it got to 2CM, it didn’t make a difference if it was 2CM or 3CM, there was already a loss of restriction and weight gain was steady and progressive.  We believe that means that this is going to be very, very difficult to treat by an endoscopic procedure.  


While weight regain following gastric bypass is becoming a much more common clinical problem, with the average patient regaining approximately 30% of the weight they lost and approximately 20-30% regaining a significant amount more, the options for patients remain limited. 


They include 


1)      obviously dietary adjustments but many patients feel that we’re kind of like Indian Givers, because at one point in time they had no hunger, they had early satiety and now they’re hungry all the time.  


2)      An increasingly investigated option is endoscopic suturing but there is no long term data.


3)      Band over bypass works for certain patients, but has many of the same problems that primary banding has 


4)      the most aggressive option is to convert the operation to a Duodenal Switch but this is a rather large operation, requires multiple anastomosis, and is an option that we reserve to patients that have considerable problems because of their weight regain.  


Thus it’s important to realize that…

  1. Our operations have limitations and that inadequate weight loss and weight regain cant just be blamed on the patient. 
  2. Bands have no effect on Ghrelin, PYY, or GLP.
  3. Gastric bypass has no valve and this can lead to inter-meal hunger.
  4. The fact that the weight gain is steady and progressive over time I think is indicative that it is physiologic
  5. We believe that increased insulin secretions after glucose challenge in bypass is indicative of the rapid emptying that occurs and the cause of inter-meal hunger. 
  6. Additionally, failing one operation should not preclude consideration for another bariatric procedure.
  7. Obesity is a chronic disease and therefore we’re going to have to be prepared to treat our patients on a long term basis and realize that bariatric surgery is not a cure for obesity but merely a control mechanism. 
  8. We need to critically analyze our procedures
  9. My opinion is that pyloric preserving procedures such as the sleeve gastrectomy and especially the duodenal switch, and maybe future varations of these procedures will replace gastric bypass as standard.

 I totally understand your worries! I am Meghann, I had my surgery Mary 1st so just under two weeks ago:) I am doing GREAT! I am young but have battled with weight issues all my life. A year ago my older sister had the Gastric Sleeve surgery performed (she was 33years old) within 7 months she had lost 111lbs. Seeing her be so happy was really an inspiration. She was told she would not be able to have children after battling Thyroid cancer and pre cancerous ovarian cyst. After the Weight loss, she is now 7 months pregnant with her first baby :) I went to the hospital May 1st for surgery and stayed there for that night and the next night. I was sent home on the 3rd and was not in need of pain medicine at all after my first night home! The surgery was the part I feared the most & actually ended up being the easiest! The hardest part is adjusting to the new lifestyle, but, you can do it! It is crazy how much you realize you depended on food when you have the surgery done. I am going to the doc on monday and will find out what I have lost in the last two weeks but even looking at my pic of surgery day compaired to a pic taken yesterday the loss in my face is crazy :) I am so excited to see where my life will go with this change! I have so much to live for and wls gave be the chance to live freely and not have my weight hold me back from anything. My best advice to you is really think about the pros and cons. I made my decission after thinking, if God takes me during surgery then it was my time to go & if I stay like this I can not do Gods work with my full ability and I will have a shorter life staying like this. Research your surgeon. Always check on who is doing your surgery, make sure they are well recommended; No history of leaks or deaths.& if you have access to a clinic that specialises in weight loss surgery rather than a regulare hospital, I recommend having the surgery done there; seeing as they work with wls on a daily basis rather than  focusing on a little of everything. If you have any imparticular questions please feel free to ask, I am new to this but would love to help :)  Good Luck!
