Case Presentation

(G.E.R.D)

INTRODUCTION

Gastroesophageal reflux disease (GERD), Gastric reflux disease, or Acid reflux disease is defined as chronic symptoms or mucosal damage produced by the abnormal reflux in the esophagus.

This is commonly due to transient or permanent changes in the barrier between the esophagus

and the stomach. This can be due to incompetence of the lower esophageal sphincter, transient

lower esophageal sphincter relaxation, impaired expulsion of gastric reflux from the esophagus,

or a hiatal hernia

CASE ABSTRACT

ANATOMY

The esophagus is a member of the digestive tract whose main responsibility is to transfer food

from the pharynx to the stomach. It measures about 10 inches in length and is tubular and

collapsible. The esophagus can be traced from the originating point of the larynx running behind

the trachea. It traces down the mediastinum of the thorax until it runs into the diaphragm, ending

just above the stomach’s opening. The esophageal hiatus refers to the opening in the diaphragm.

Nonkeratinized stratified squamous epithelium lines the esophagus. The walls themselves are

either created by skeletal muscles or by smooth muscle tissue. Skeletal muscle lines the upper

1/3 of the esophagus, while the middle 1/3 is a combination of the two muscle tissues, leaving

the remaining 1/3 as smooth muscle tissue. Where the stomach and the esophagus meet, there is

a thickening of the circular muscle fibers, creating the gastroesophageal sphincter, or the lower

esophageal sphincter. This sphincter is responsible for maintaining the food and fluids inside the

stomach, preventing regurgitation up into the esophagus. Air in the lungs creates an additional

pressure in the lower thoracic region, encouraging regurgitation of foods and fluids.

The Mechanisms of Swallowing

Deglutition is the term given to the process of swallowing, a highly mechanical and functionally

complex process that allows the initiation of digestion to occur. Deglutition is typically described

in three basic phases, allowing for clarity.

The initial stage of deglutition is preceded by mastication if there is a solid in the process. This is

a voluntary stage, meaning that a human must begin this stage consciously. The oral cavity

closes and the process of breathing is temporarily suspended. The bolus has been formed through

the process of mastication, and the tongue then lifts the bolus firm against the transverse palatine

folds of the hard palate. The mylohyoid muscle and the styloglossus muscle contract to produce

this experience.

The secondary stage takes over from this point, passing the bolus through the pharynx. The

second stage of deglutition is involuntary. Sensory receptors that are positioned at the opening of

the oropharynx stimulate the secondary action. The tongue is pressing the bolus against the

transverse palatine folds of the hard palate, which creates a seal against the nasopharynx. This

not only prevents the bolus from entering the airway, but it also stimulates the pressure senses of

the oropharynx and forces the bolus into the opening. The soft palate along with the uvula close

off the rest of the nasopharynx while the bolus passes into the gullet, and the hyoid bone and the

larynx elevate protectively. The constrictor muscles of the pharynx then contract in a rhythmic

and intentional sequence in order to force the bolus through the pharynx, where it will then enter

the esophagus. This entire stage can be completed in less then a second.

The final stage of deglutition is also involuntary, and it deals specifically with the bolus entering

and passing through the esophagus. Peristalsis kicks in naturally and the bolus in pressured down

the esophagus. Fluids are rushed through this entire process, all three stages, in under a second,

while an average sized bolus takes approximately 5 to 8 seconds to complete the three stages.

Pathophysiology

The development of GE reflux disease depends on a combination of the following four factors: (1) defective anti-reflux mechanism, (2) the presence of caustic gastric contents, (3) poor esophageal clearance, (4) diminished esophageal mucosal resistance.

1) Anti-reflux mechanism

As intra-abdominal pressure is always greater than intrathoracic pressure, if it were not for an anti-reflux barrier, GE reflux would be occurring almost constantly. The role of the esophageal sphincter refers to a segment of specialized circular mucosa at the GE junction approximately 3 cm in length which maintains a pressure 10 mmHg to 40 mmHg higher than the pressure of the stomach thereby preventing GE reflux.

Before the advent of widespread use of esophageal manometry, primary LES hypotonia was felt to account for all cases of GE reflux disease. Using modern manometric techniques, however, it has been demonstrated that only the minority (10-20%) of patients with GE reflux disease do in fact have lower than normal LES pressures. It is now believed by most investigators that the presence of transient LES relaxation explains GE reflux in the majority of patients. Normally the LES relaxes briefly after a peristaltic wave to allow passage of the bolus from the esophagus into the stomach. Transient LES relaxation refers to inappropriate relaxation of the sphincter occurring without a preceding peristaltic wave and lasting up to 30 seconds in duration. These transient sphincter relaxations allow for reflux of caustic gastric contents into the esophageal body.

The presence of a hiatus hernia, originally felt to be central in the pathogenesis of GERD has continued to be the subject of much debate and controversy. Many patients have GERD in the absence of hiatus hernias, and only the minority of patients with hiatus hernias develop GE reflux. Recent studies on cats and human beings have shown that the crural diaphragm does play a role in maintaining basal LES pressure. It is unclear, however, how important a factor this is in most patients for maintaining LES competence.

2) Gastric Contents

In order for gastroesophageal reflux to result in esophageal damage and symptomatic heartburn there must be material in the stomach which is caustic to esophageal mucosa. Clearly acid present in the stomach is the primary caustic agent, underscored

by the dramatic improvement almost all patients feel and endoscopic exam demonstrates in patients with severe esophagitis. The role of other caustic agents such as pepsin, bile salts, pancreatic enzymes and bicarbonate is less clear.

People with GE reflux disease have not been shown to be hypersecreters of gastric acid, however, patients with delayed gastric emptying either on the basis of pyloric stenosis or gastroparesis frequently develop resultant severe GE reflux.

3) Esophageal Clearance

In order for the caustic reflux to cause tissue damage it must be in contact with the mucosa for a sufficient period of time. Normally refluxed material is cleared by a combination of gravity and secondary peristalsis. In patients with disordered esophageal peristalsis, particularly scleroderma, the material refluxed into the esophagus has the opportunity to have prolonged contact with the esophageal mucosa thereby causing severe erosive damage especially when the patient is supine. Additionally important clearance is salivary and esophageal bicarbonate formation which helps neutralize the refluxed acid.

4) Esophageal Mucosal Resistance

A more recently identified and poorly understood component of the defensive mechanism in preventing GERD is esophageal mucosal resistance. The factors involved in esophageal mucosal resistance to acid are much less well understood and much more poorly developed than mucosal resistance factors of the stomach. What is known, however, is that patients can develop erosive esophagitis in the setting of very minimal GE reflux documented by a 24 hour pH probe, and on the other hand there are patients with severe GE reflux as documented on pH probe which do not develop significant esophageal damage.Cheap canadian pharmacy
