Sleeve And Weight Regain

July 22, 2019 9:50 am

Sleeve gastrectomy has become the most frequently performed operation in the US. Sleeve as a part of the Duodenal Switch or as a stand alone operation has been offered in our practice for nearly 20 years. As a precondition to this, patients’ choosing to have the sleeve, especially with high BMI (>45) and those with metabolic conditions (diabetes, high cholesterol or triglycerides, PCOS, and others) we have always recommended Duodenal Switch as the procedure of choice instead of the Sleeve Gastrectomy due to improved and lasting co-morbid resolution  and weight loss maintenance with Duodenal Switch. It has been know for years that a sizable number of patients having the sleeve will experience weight regain requiring conversion to the duodenal switch or the RNY Gastric Bypass. Majority of the patients having gained weight after sleeve, or experiencing the return of co-morbidities after a transient resolution during the their weight loss phase, should only be revised to the Duodenal switch operation in my opinion. The alternative procedures of SIPS and SADI or similar single anastomosis operation with confusing nomenclature should be avoided, since as of the publication of this blog they are still considered investigational by the American Society for Metabolic and Bariatric Surgery (ASMBS) with no long term data.  The only plausible reason for revision of the Sleeve to the gastric bypass (RNY) would be those patients who are experiencing reflux. Felsernreich et.al. demonstrated that 10 years after sleeve gastrectomy  33% were requiring revisions of their sleeve due to weight regain or reflux. 66% needed revision for weight loss and only 34% for reflux. Those patients who have revision to gastric bypass (in their practice all being revised with two exception) had resolution of their reflux however had no sustained weight loss after the revisions. This supports our position that we have had for years that the those patient who had the sleeve and are experiencing weight regain, recurrence of comorbidities inadequate weight loss ahould all be revised to the duodenal switch operation.

Gastroesophageal Reflux: Bile Vs. Acid

May 14, 2019 12:52 pm

Gastroesophageal (GE) reflux is the condition when the stomach content are able to “reflux” back thru an incompetent lower esophageal sphincter (LES)  into the esophagus.

Gastroesophageal reflux Disease (GERD) is the clinical condition which is the result of long standing reflux and results in microscopic and visible changes to the inner lining of the esophagus, esophageal mucosa.

GERD is a non descriptive as to the cause of the condition. It only states that the content of the stomach have been irritating the lining of the esophagus on chronic bases. This can be caused by an anatomical abnormality fo the GE junction (Hiatal Hernia), or may be related to disfunction the LES. Other possible causes of the GERD may be infection (H.Pylori) environmental (stress) and dietary (nicotine, alcohol, caffeine, spicy food) in origin.

So far we have not clarified the chemical nature of the the refluxed content.

In Acid Reflux, the relative acid overproduction of acidic secretion and the exposure of the esophageal mucosa is what needs to be addressed. This is accomplished by acid suppression medications, Anti Histamine (H2 blockers) Proton pump inhibitors (PPI) for example.  The physiology, and the mechanism involving this condition is well understood. As a surgeon, we do however see patients who should have had surgical intervention. The initial mode of therapy for a patient with documented acid reflux, and or symptomatic hiatal hernia is placing them on medication. These patients are then recommended to have related upper endoscopy. Patients who do not improve or where deterioration of the esophageal mucosa, presence of precancerous cells, then the patients are referred for surgical intervention.

Bile Reflux, contrary to acid reflux may have very little if anything with the LES. The symptoms experienced by the patient may be as ofter related to the excessive bile in the stomach seen frequently

after cholecystectomy, or in those patients with dysfunctional gallbladder (low EF on HIDA scan).

GERD, Nausea and Vomiting- Don’t ignore it!

April 28, 2015 11:30 am

Gastroesophageal Reflux Disease is a serious matter and should not be left untreated. It is know as heartburn or reflux and if you are experiencing more than twice a week you should be evaluated by a physician to investigate the cause. Listed below are some of the causes and end results of not treating GERD.

Esophagitis – An irritant that can be acid, bile, food and digestive enzymes coming back up the esophagus can cause irritation and swelling in the esophagus. If left untreated, it can damage the lining of the esophagus to the point of erosion and scarring. Bile Reflux may also be a cause of esophagitis and Duodenogastroesphogeal reflux (DGER). Bile Reflux information here.

Esophageal Stricture – Scar tissue can cause the lumen of the esophagus to become smaller and narrow.  This stricture makes it difficult or painful to swallow foods. If a stricture is narrow enough food may become stuck and require intervention for removal and treatment.  This can also put a person at risk for choking. The treatment includes ballon dilation with an endoscope and in cases where it recurs surgery may be required.

Esophageal Ulceration– If GERD is left untreated it can progress to actual ulcerations in the esophagus.  Patients may cough up or vomit blood or see it in their stool as dark tarry or coffee ground type stool.

Gastric Stricture– After weight loss surgery such as sleeve gastrectomy, RNY Gastric Bypass, Duodenal Switch, SADI/Loop,  Adjustable Gastric Banding, or other gastric surgeries a narrowing of the inner opening of the stomach can result from scar tissue forming.  This will require a surgical procedure to rectify.  The symptoms can be food intolerance, full feeling, nausea and/or vomiting. (See pictures below)

Hiatal Hernia– An anatomical weakening or enlargement of the opening of the diaphragm muscle where the esophagus meets the stomach.  This defect can allow a portion of the stomach to slide or roll into the chest cavity. This then causes reflux of gastric juice and content.  Hiatal Hernia’s can also form on weight loss surgical patients.  There are several examples within this blog here.

Breathing Difficulties– The acid aspiration while sleeping can make asthma and other breathing difficulties worst and can cause coughing and other issues.

Dental Issues – The acid, food, digestive enzymes backing up into the esophagus and mouth can cause dental issues such as erosion and tooth decay.  In regards to dental issues after weight loss surgery there are also other vitamin and mineral deficiencies that can cause oral health issues. Dental Issues after WLS here.

Lower Quality of Life– GERD can affect a person’s quality of life.  If you are in discomfort from acid reflux or having food intolerance it can make life difficult.  It can also alter food choices and impact nutrition.

Barrets Esophagus– Pre-cancerous changes in the bottom portion of the esophagus due to long term acid exposure from gastric reflux. Diagnosis requires and endoscopic procedure (EGD) and biopsy.

Esophageal Cancer– There is a significant rise in the western world in esophageal adenocarcinoma. The main risk factors are alcohol use, smoking, untreated GERD, and poor diet.

Reflux and difficulty with swallowing caused by stricture is not normal. These problems are quite frequently encountered as complication of Adjustable gastric banding, with slipped band or a band that is too tight and scarred in placed resulting is belt effect. This results in the esophagus not being able to empty and propel the food down. The end result is significant reflux, with difficulty swallowing, nausea, vomiting etc.  Similar problems are seen with Gastric bypass where the anastomosis between the stomach pouch and the small bowel RNY limb is too narrow. In Gastric Sleeve and Duodenal Switch operations, is the sleeve is made too narrow, or misshaped (hour glass, funnel, cork screw) it will result in the patient having reflux and symptoms of stricture. One specific problem with the new operation of SADI is the concern for  risk of bile reflux, similar to the BillRoth I procedure.

Adjustable Gastric Band Removal & Hiatal Hernia Repair

April 21, 2015 6:30 pm

As it is a recurrent theme, a patient presents with a band that was placed years ago with marginal weight loss over a short period of time. Multiple office visits to the same center for band adjustments, which only results in worsening nausea, vomiting and reflux to the point of having difficulty with taking fluids in. The irony was that the patient was being blamed for the symptoms as to “…eating the wrong food, …eating too much, etc” The patient presented to the Emergency Room and was taken to the Operating Room within few hours for a partially slipped band and a Hiatal Hernia was also identified. The adjustable gastric band was removed and the Hiatal hernia was repaired.

Hiatal Hernia Repair- Reflux and Adjustable Gastric Band Revision

January 14, 2015 3:47 pm

Hiatal Hernia is an anatomical weakening or enlargement of the opening in the diaphragm where the esophagus meets the stomach. The defect can allow a section of stomach to slide or roll into the chest cavity. This causes the reflux of stomach content back to the esophagus. Esophageal Reflux may also be occur without the presences of a Hiatal hernia. It is reported that approximately 60% of people over 50 have a Hiatal hernia with about 9% being symptomatic.

However, over the years we have also noticed a significant increase in reflux disease in patients who have had adjustable gastric band placed.  Quite frequently the reflux symptoms after the band is ” blamed” on the patient’s eating habit. Most of the time all studies are reported as “normal” and the  complaints are discounted. Other symptoms of Hiatal hernia may or may not include shortness of breath, heart palpitations, or a feeling of food being stuck.

It is important to confirm the presence or absence of a hiatal hernia when considering revision from an  adjustable gastric band procedure.   Any hiatal hernia identified either before surgery or at the time of the operation will need to be repaired surgically.

With a hiatal hernia repair, the opening is made smaller, and the esophagus, stomach and the junction between them is returned to the proper location to minimize-eliminate reflux.
