What is GERD
GERD states it is a condition that occurs
when the refluxed stomach contents lead
to trouble.
Disorder in lower esophagus sphincter
GERD affects all ages especially after 40
years
![Page 7: Gerd presentation ( Case study )](https://reader034.vdocuments.us/reader034/viewer/2022052117/5a669aa27f8b9ac5128b5a27/html5/thumbnails/7.jpg)
The gender doesn't play a role in the
disease .
The mortality of GERD is rare .
Death occur in Barrett’s esophagus that
lead to esophagus adenocarcinoma

Diagnosis
Symptoms (Heartburn , Regurgitation)
Barium Swallow

Barium Swallow
Barium sulfate is a metallic
compound that shows up on X-
rays
![Page 10: Gerd presentation ( Case study )](https://reader034.vdocuments.us/reader034/viewer/2022052117/5a669aa27f8b9ac5128b5a27/html5/thumbnails/10.jpg)
The X-rays track its path
through patient digestive
system .

containing this solution

An upper endoscopy
visually examine upper
digestive system with a tiny
camera on the end of a long,
flexible tube.
![Page 12: Gerd presentation ( Case study )](https://reader034.vdocuments.us/reader034/viewer/2022052117/5a669aa27f8b9ac5128b5a27/html5/thumbnails/12.jpg)
Esophageal manometry
Esophageal manometry is a test to measure how
well the esophagus is working.
A thin, pressure-sensitive tube is passed through
patient nose, down the esophagus, and into patient
stomach.
![Page 13: Gerd presentation ( Case study )](https://reader034.vdocuments.us/reader034/viewer/2022052117/5a669aa27f8b9ac5128b5a27/html5/thumbnails/13.jpg)
What is GERD ?
GERD states it is a condition that occurs when the refluxed stomach contents lead to trouble symptoms and/or complications.
GERD affects all ages espacially after 40 years.
The gender doesn't play a role in the disease
The mortality of GERD is rare .
![Page 14: Gerd presentation ( Case study )](https://reader034.vdocuments.us/reader034/viewer/2022052117/5a669aa27f8b9ac5128b5a27/html5/thumbnails/14.jpg)
Phathophysiology
The main problem in the
development of GERD is the
abnormal reflux of gastric
contents from the stomach into
the esophagus.
![Page 15: Gerd presentation ( Case study )](https://reader034.vdocuments.us/reader034/viewer/2022052117/5a669aa27f8b9ac5128b5a27/html5/thumbnails/15.jpg)
This is due to :
1- Lower Esophageal Sphincter Pressure
2- anatomical causes
![Page 16: Gerd presentation ( Case study )](https://reader034.vdocuments.us/reader034/viewer/2022052117/5a669aa27f8b9ac5128b5a27/html5/thumbnails/16.jpg)
![Page 17: Gerd presentation ( Case study )](https://reader034.vdocuments.us/reader034/viewer/2022052117/5a669aa27f8b9ac5128b5a27/html5/thumbnails/17.jpg)
GERD Causes
*Lower Esophageal Sphincter Pressure
Different mechanisms by which defective
LES pressure lead gastroesophageal
reflux.
![Page 18: Gerd presentation ( Case study )](https://reader034.vdocuments.us/reader034/viewer/2022052117/5a669aa27f8b9ac5128b5a27/html5/thumbnails/18.jpg)
1- LES relaxations that are not
associated with swallowing. Although
the exact mechanism is unknown.
2- postprandially, may play an important
role in symptom-based esophageal
reflux syndromes.
3- intraabdominal pressure (stress
reflux)
![Page 19: Gerd presentation ( Case study )](https://reader034.vdocuments.us/reader034/viewer/2022052117/5a669aa27f8b9ac5128b5a27/html5/thumbnails/19.jpg)
Anatomical factor
Disruption of the normal anatomic barriers
by a hiatal hernia (when a portion of the
stomach
protrudes through the diaphragm into the
chest) was once thought to be a primary
etiology of
gastroesophageal reflux
![Page 20: Gerd presentation ( Case study )](https://reader034.vdocuments.us/reader034/viewer/2022052117/5a669aa27f8b9ac5128b5a27/html5/thumbnails/20.jpg)

Special casePregnancy
1- hormonal effects on esophageal muscle
2- physical factors (increased intraabdominal
pressure)
![Page 22: Gerd presentation ( Case study )](https://reader034.vdocuments.us/reader034/viewer/2022052117/5a669aa27f8b9ac5128b5a27/html5/thumbnails/22.jpg)
Composition of Refluxate
the combination is gastric acid, pancreatic
enzymes pepsin, and/or bile is a potent
refluxate in producing esophageal
damage.
The composition, pH , volume of the
refluxate
are important aggressive factors in
determining the GERD
![Page 23: Gerd presentation ( Case study )](https://reader034.vdocuments.us/reader034/viewer/2022052117/5a669aa27f8b9ac5128b5a27/html5/thumbnails/23.jpg)
Defensive mechanism
Esophageal clearance
Mucosal resitance
Gastric empting

Esophageal manometry
Esophageal manometry is a test to measure how

A thin, pressure-sensitive tube is passed through
patient nose, down the esophagus, and into patient
stomach.
![Page 35: Gerd presentation ( Case study )](https://reader034.vdocuments.us/reader034/viewer/2022052117/5a669aa27f8b9ac5128b5a27/html5/thumbnails/35.jpg)
After the tube is in the stomach, the tube is pulled
slowly back into patient esophagus.
At this time, patient is asked to swallow
The pressure of the muscle contractions is
measured along several sections of the tube.
While the tube is in place, other studies of your
esophagus may be done. The tube is removed after
the tests are completed.
![Page 36: Gerd presentation ( Case study )](https://reader034.vdocuments.us/reader034/viewer/2022052117/5a669aa27f8b9ac5128b5a27/html5/thumbnails/36.jpg)
Ambulatory–pH monitoring
test
Small tube passed through the nose into
the esophagus at the level of the LES.
A pH sensor at the tip of the tube collected
on a portable computer.

Treatment
1) Non-Pharmacologic treatment
Lifestyle changes
2) Pharmacologic treatment therapy with antacids,nonprescription H2-receptor antagonists, and/ornonprescription proton pump inhibitors Providesymptomatic relief, and prescription strengthacid-suppression therapy .
3) Anti-reflux surgery .
![Page 38: Gerd presentation ( Case study )](https://reader034.vdocuments.us/reader034/viewer/2022052117/5a669aa27f8b9ac5128b5a27/html5/thumbnails/38.jpg)
Elevating the head end of the bed by approximately (15
to 20 cm) with a foam wedge under the mattress .
Weight loss
Avoid food that may decrease lower esophageal
sphincter like ( fat, chocolate, cola, spearmint,
alcohol(wine), pepper, Garlic, onion )
Avoid food that have the direct irritant of esophageal
mucosa like (spicy, citrus juice, tomato, coffee,
Tobacco )
Include protein rich meal in diet (augment ( increase )
lower esophageal sphincter )
Always take drugs in the setting upright .
Avoidance of tight-fitting clothes .

The goal of antireflux surgery is to reestablish the antirefluxbarrier, to position the LES within the abdomen where itis under positive ( intraabdominal ) pressure, and to closeany associated defect in the diaphragmatic hiatus byreinforcing the crural muscles .
Antireflux surgery should be considered for patients :
Who fail to respond to pharmacologic treatment.
Who opt for surgery despite successful treatmentbecause of lifestyle considerations, including age, time,or expense of medications.
Who have complications of GERD (e.g., Barrett’sesophagus, strictures).
Who have atypical symptoms and reflux documentedwith ambulatory pH monitoring .
Anti-reflux surgery

A: This patient has high lipid profile ( Total cholesterol, LDL,TG, Low HDL )
Which is additional risk for CV events, and he doesn't takeAnti-hyperlipidemia therapy .
P:
Aim /
• Normal level of lipid profile ( TC=less than 200 mg/dl,LDL=below 100 , TG=below 150 , HDL=40-60 or more
• Decrease risk for CV

Glyburide didn't decrease his blood glucose.
This patient didn't use preferred initial agent which is
has beneficial effect in this pt. (wt. gain, high risk of
CV event )
![Page 67: Gerd presentation ( Case study )](https://reader034.vdocuments.us/reader034/viewer/2022052117/5a669aa27f8b9ac5128b5a27/html5/thumbnails/67.jpg)
★Unsafe drug therapy :S: ____________
O: BMI = 31.2 obese
A:
Obesity in this pt. may results from use Glybruide
(it's is one of adverse effect: wt. gain),
This is risk factor which increase CV events in the
other risk factors present in this pt.

P:Aim
Control blood glucose level

According to :
Cockreft-gault Eq. CrCl = 59.34 ml/min ( in stage 3 -
moderate- )
Dose adjustment of Metformin in renal disease if
CrCl<30 ml/min
Monitoring of Metformin :
Efficacy :
Fasting glucose test
A1C
Toxicity :
Vit B12 level ( it cause vit B12 deficiency ) .
