GASTROESOPHAGEAL REFLUX DISEASE (GERD)
1. Definition b. GERD common, affecting 15 – 20%
of adults c. 10% persons experience daily
heartburn and indigestion d. Because of location near other
organs symptoms may mimic other illnesses including heart problems
a. Gastroesophageal reflux is the backward flow of gastric content into the esophagus.
![Page 4: Gerd and post op mgmt. dr. blatchford 1.2014](https://reader037.vdocument.in/reader037/viewer/2022102804/547e9822b47959bb508b4be6/html5/thumbnails/4.jpg)
GASTROESOPHAGEAL REFLUX DISEASE (GERD)
2.Pathophysiology a. Gastroesophageal reflux results from
transient relaxation or incompetence of lower esophageal sphincter, sphincter, or increased pressure within stomach
b. Factors contributing to gastroesophageal reflux
1.Increased gastric volume (post meals) 2.Position pushing gastric contents close
to gastroesophageal juncture (such as bending or lying down)
3.Increased gastric pressure (obesity or tight clothing)
4.Hiatal hernia
![Page 5: Gerd and post op mgmt. dr. blatchford 1.2014](https://reader037.vdocument.in/reader037/viewer/2022102804/547e9822b47959bb508b4be6/html5/thumbnails/5.jpg)
GASTROESOPHAGEAL REFLUX DISEASE (GERD)
c.Normally the peristalsis in esophagus and bicarbonate in salivary secretions neutralize any gastric juices (acidic) that contact the esophagus; during sleep and with gastroesophageal reflux esophageal mucosa is damaged and inflamed; prolonged exposure causes ulceration, friable mucosa, and bleeding; untreated there is scarring and stricture
3.Manifestations a. Heartburn after meals, while bending over, or
recumbent b. May have regurgitation of sour materials in
mouth, pain with swallowing c. Atypical chest pain d. Sore throat with hoarseness e. Bronchospasm and laryngospasm

GASTROESOPHAGEAL REFLUX DISEASE (GERD)
4. Complications a. Esophageal strictures, which can
progress to dysphagia b. Barrett’s esophagus: changes in cells
lining esophagus with increased risk for esophageal cancer
5. Collaborative Care a. Diagnosis may be made from history
of symptoms and risks b. Treatment includes
1.Life style changes2.Diet modifications3.Medications
![Page 10: Gerd and post op mgmt. dr. blatchford 1.2014](https://reader037.vdocument.in/reader037/viewer/2022102804/547e9822b47959bb508b4be6/html5/thumbnails/10.jpg)
GASTROESOPHAGEAL REFLUX DISEASE (GERD)
6. Diagnostic Tests a. Barium swallow (evaluation of
esophagus, stomach, small intestine) b. Upper endoscopy: direct
visualization; biopsies may be done c. 24-hour ambulatory pH monitoring d. Esophageal manometry, which
measure pressures of esophageal sphincter and peristalsis
e. Esophageal motility studies
![Page 11: Gerd and post op mgmt. dr. blatchford 1.2014](https://reader037.vdocument.in/reader037/viewer/2022102804/547e9822b47959bb508b4be6/html5/thumbnails/11.jpg)
GASTROESOPHAGEAL REFLUX DISEASE (GERD)
7. Medications a. Antacids for mild to moderate
symptoms, e.g. Maalox, Mylanta, Gaviscon b. H2-receptor blockers: decrease acid
production; given BID or more often, e.g. cimetidine, ranitidine, famotidine, nizatidine
c. Proton-pump inhibitors: reduce gastric secretions, promote healing of esophageal erosion and relieve symptoms, e.g. omeprazole (prilosec); lansoprazole (Prevacid) initially for 8 weeks; or 3 to 6 months
d. Promotility agent: enhances esophageal clearance and gastric emptying, e.g. metoclopramide (reglan)
![Page 12: Gerd and post op mgmt. dr. blatchford 1.2014](https://reader037.vdocument.in/reader037/viewer/2022102804/547e9822b47959bb508b4be6/html5/thumbnails/12.jpg)
GASTROESOPHAGEAL REFLUX DISEASE
8. Dietary and Lifestyle Management a. Elimination of acid foods (tomatoes, spicy,
citrus foods, coffee) b. Avoiding food which relax esophageal
sphincter or delay gastric emptying (fatty foods, chocolate, peppermint, alcohol)
c. Maintain ideal body weight d. Eat small meals and stay upright 2 hours
post eating; no eating 3 hours prior to going to bed
e. Elevate head of bed on 6 – 8 blocks to decrease reflux
f. No smoking g. Avoiding bending and wear loose fitting
clothing
![Page 13: Gerd and post op mgmt. dr. blatchford 1.2014](https://reader037.vdocument.in/reader037/viewer/2022102804/547e9822b47959bb508b4be6/html5/thumbnails/13.jpg)
GASTROESOPHAGEAL REFLUX DISEASE (GERD)
9. Surgery indicated for persons not improved by diet and life style changes
a. Laparoscopic procedures to tighten lower esophageal sphincter
b. Open surgical procedure: Nissen fundoplication
10. Nursing Care a. Pain usually controlled by treatment b. Assist client to institute home plan
![Page 14: Gerd and post op mgmt. dr. blatchford 1.2014](https://reader037.vdocument.in/reader037/viewer/2022102804/547e9822b47959bb508b4be6/html5/thumbnails/14.jpg)
HIATAL HERNIA
1. Definition a. Part of stomach protrudes through
the esophageal hiatus of the diaphragm into thoracic cavity
b. Predisposing factors include: Increased intra-abdominal pressure Increased age Trauma Congenital weakness Forced recumbent position
![Page 15: Gerd and post op mgmt. dr. blatchford 1.2014](https://reader037.vdocument.in/reader037/viewer/2022102804/547e9822b47959bb508b4be6/html5/thumbnails/15.jpg)
HIATAL HERNIA
c. Most cases are asymptomatic; incidence increases with age
d. Sliding hiatal hernia: gastroesophageal junction and fundus of stomach slide through the esophageal hiatus
e. Paraesophageal hiatal hernia: the gastroesophageal junction is in normal place but part of stomach herniates through esophageal hiatus; hernia can become strangulated; client may develop gastritis with bleeding
![Page 16: Gerd and post op mgmt. dr. blatchford 1.2014](https://reader037.vdocument.in/reader037/viewer/2022102804/547e9822b47959bb508b4be6/html5/thumbnails/16.jpg)
HIATAL HERNIA
2.Manifestations: Similar to GERD3.Diagnostic Tests a. Barium swallow b. Upper endoscopy4.Treatment a. Similar to GERD: diet and lifestyle
changes, medications b. If medical treatment is not effective or
hernia becomes incarcerated, then surgery; usually Nissen fundoplication by thoracic or abdominal approach Anchoring the lower esophageal sphincter by wrapping a
portion of the stomach around it to anchor it in place
![Page 17: Gerd and post op mgmt. dr. blatchford 1.2014](https://reader037.vdocument.in/reader037/viewer/2022102804/547e9822b47959bb508b4be6/html5/thumbnails/17.jpg)
NISSEN FUNDOPLICATION
Average hospital stay 1-2 days Resolution of symptoms at 1 year 94% Major complications 2% Long term complications 2-62% (gas
bloat and difficulty swallowing) Generally the larger the hiatal hernia,
the greater the crural dissection. Patient may have subcutaneous air present for the 1st 48 hours post-op.

GASTRIC SLEEVE
Part of stomach is removed making a small reservoir for food
Helps you lose weight with restrictive properties and stimulates the feeling of fullness
Excellent safety profile Outpatient or only 24 hour
stay in hospital
![Page 26: Gerd and post op mgmt. dr. blatchford 1.2014](https://reader037.vdocument.in/reader037/viewer/2022102804/547e9822b47959bb508b4be6/html5/thumbnails/26.jpg)
GASTRIC BYPASS
Creates small proximal gastric pouch that is connected to the jejunum bypassing the duodenum
Causes weight loss with restrictive and malabsorbtive properties
Hospital stay 2-3 days
![Page 27: Gerd and post op mgmt. dr. blatchford 1.2014](https://reader037.vdocument.in/reader037/viewer/2022102804/547e9822b47959bb508b4be6/html5/thumbnails/27.jpg)
POST OPERATIVE CARE
Pain Control Diet Protocol I &Os Ambulation Patient stays on antireflux medication
at least 2 weeks post operatively Wound assessment
![Page 28: Gerd and post op mgmt. dr. blatchford 1.2014](https://reader037.vdocument.in/reader037/viewer/2022102804/547e9822b47959bb508b4be6/html5/thumbnails/28.jpg)
MAJOR SURGICAL COMPLICATIONS AND CONCERNS
Pneumonia Myocardial infarction DVT or PE Wound infection Anastamotic leak Band Slippage Esophageal perforation or stomach perforation Pneumothorax Internal hemmorage Slipped nissen Internal hernia Wound dehiscence
![Page 29: Gerd and post op mgmt. dr. blatchford 1.2014](https://reader037.vdocument.in/reader037/viewer/2022102804/547e9822b47959bb508b4be6/html5/thumbnails/29.jpg)
TROUBLESHOOTING
Persistent Tachycardia above baseline may be the earliest sign of a possible anastamotic leak
Patient population at even higher risk for DVT, MI, Post op pneumonia, atelectasis, and wound infection than the general population.
Early ambulation is key For provider calls it is of utmost important to
provide all vitals, trends, as well as wound assessment and I&Os.
![Page 30: Gerd and post op mgmt. dr. blatchford 1.2014](https://reader037.vdocument.in/reader037/viewer/2022102804/547e9822b47959bb508b4be6/html5/thumbnails/30.jpg)
TROUBLESHOOTING
Decreased urine output (less than 30 cc per hour in the average adult)
Persistent pain despite liberal use of narcotics Tachycardia Shortness of breath Sudden onset of subcutaneous air (however may be
normal if extensive crural disection). Mild fever common postop if <101 F. Always assess the whole patient (not one single value),
Including the wounds prior to assuming there is a problem.
If it is a surgical patient, the surgeon should be called
![Page 31: Gerd and post op mgmt. dr. blatchford 1.2014](https://reader037.vdocument.in/reader037/viewer/2022102804/547e9822b47959bb508b4be6/html5/thumbnails/31.jpg)
IN SUMMARY
Be paranoid Be thorough with assessment Be organized Recognize early signs of possible life
