Gastritis is a general term used for the description of symptoms associated with several very different physical conditions and require different treatments based on their ideology . Gastritis, gastroesophageal reflux, and bile reflux gastritis

Gastritis may be caused by excess acid or bile in the stomach. Some patients may have gastroesophageal reflux due to a hiatal hernia, which needs to be treated surgically with Nissen fundoplication, regardless of the size of the hernia, contrary to what gastroenterologists recommend by prescribing antacids for an extended period. I have seen patients who have had one cm hiatal hernia and have been very symptomatic, and others who have had larger hiatal hernias and have been asymptomatic. Size should not be a determinant of whether the patient has had or will have a hernia repair or not.

 

 

Billiary Diversion is the definitive surgical procedure for Bile Reflux Gastritis.

The FDA had initially approved almost all PPI’s, and antacids with an explicit limit placed on the duration of the therapy, which ranged in days to weeks. At that time there were no long term studies done on the health benefits, or side effects of the long term use of the PPI.

This Summary Letter outlines all the concerns dating back to 2011. I have found the information in this letter a good overview of the supporting medical evidence and lack of any long term data in regards to long term PPI.

The FDA made changes in the Black Box warning of the PPI medications.  This was done with the mounting evidence and the health concerns of long term PPI use.

PPI’s have been shown to have detrimental long term side effects. It is prudent that a patient is continuously monitored and evaluated for identification of the possible underlying causes of the reflux, that may be the reason for the PPI use. There are a whole host of potential causes of reflux and other options for treatment.

There have been numerous studies recently published:

It can lead to increase risk of fractures and in a large study from the VA system it has been associated with the risk of premature death

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

Gastroesophageal reflux Disease (GERD) is a clinical condition caused by long-standing reflux that results in microscopic and visible changes to the inner lining of the esophagus and esophageal mucosa.

GERD is nondescript as to the cause of the condition. It only states that the stomach contents have been irritating the lining of the esophagus on a chronic basis. This can be caused by an anatomical abnormality of the GE junction (hiatal hernia) or may be related to dysfunction of the LES. Other possible causes of 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 refluxed content.

In Acid Reflux, the relative acid overproduction of acidic secretion and the exposure of the esophageal mucosa need to be addressed. This is accomplished by acid suppression medications, anti-histamine (H2 blockers), and Proton pump inhibitors (PPIs).  The physiology and the mechanism involving this condition are well understood. As a surgeon, however, I do 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 a related upper endoscopy. Patients who do not improve or where deterioration of the esophageal mucosa and the presence of precancerous cells are referred for surgical intervention.

Bile Reflux, contrary to acid reflux, may have tiny, if anything, to do with the LES. The symptoms experienced by the patient may be as after related to the excessive bile in the stomach, which is seen frequently

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

The treatment of Bile reflux is Duodenal Switch without the associated sleeve gastrectomy component in addition to repair of hiatal hernia if present. Ann Surg. 2007 Feb; 245(2): 247–253.

Gastrointestinal (GI) Bleed following weight loss surgery is rare but does require knowledge of the particular bariatric surgical procedure the patients has and how to proceed with diagnostics to fully evaluate the situation. Acute or chronic gastrointestinal bleeding can cause anemia in patients. However, Anemia may also be caused by nutritional deficiencies (iron, vitamin , minerals), Kidney disease, bone marrow disease and others. The work-up for anemia following weight loss surgery follows a routine protocol. If there is an evidence of bleeding from intestine (bloody emesis, bloody bowel movement, “tar” like black bowel movements) then the diagnostic work up would include an upper and lower endoscopy.

Endoscopic Procedures:

Upper endoscopy Esophagogastroduodenoscopy (EGD): evaluates the esophagus, stomach and a limited area of the duodenum past pyloric valve.

Lower endoscopy Colonoscopy or coloscopy: evaluates the rectus and the entire colon.

Between these two tests, there is still a considerable amount of the small bowel that is not accessible or visualized with endoscopic procedures. For the small bowel, examination Capsule endoscopy is an option in an intact GI tract. Patients who have had Gastric bypass RNY or the Duodenal Switch, the large segments of the small bowel can not be visualized or examined with capsule endoscopy.

Patients who have had Duodenal Switch, Gastric Bypass and SADI – S would need a tagged red cell scan or CT angiography if GI bleed is suspected in areas of the small intestine that are inaccessible by endoscopic procedures.

Upper Endoscopy (Esophagogastroduodenoscopy- EGD)

Gastrointestinal endoscopic procedures can be done in patients after the duodenal switch operation.
An upper endoscopy in an intact anatomy, involves examination of the esophagus, stomach, pyloric valve, and the duodenum including the ampulla of vater. This is where the biliopancreatic secretions are added into the GI track for absorption of the nutrients.
