|
Loss of peristalsis in distal esophagus and failure of LES relaxation with swallowing
Treatment: Meds (nitrates and CCB), botulinum toxin injections, dilation of LES, surgical myotomy (cut fibers of LES) |
|

|
Progressive dysphagia for solids and liquids, vomit undigested food, weight loss, globus sensation
PE: weight loss Diagnosis: barium swallow (suggestive) - dilated esophagus terminates in beak-like narrowing; esophageal manometry (confirmatory) - tube through nose to esophagus that measures peristalsis |
|
What is gastroesophageal reflux disease (GERD)?
|
Abnormal movement of gastric contents from stomach into esophagus leading to troublesome symptoms or mucosal damage from inflammation
Applied to pts with symptoms suggestive of reflux , but not necessarily with esophageal inflammation Very common |
|
What is physiologic and pathologic reflux?
|
Physiologic: contents from stomach come up to esophagus then go back down; episodes occur postprandially, short-lived, asymptomatic, and rarely occur during sleep
Pathologic: associated with symptoms or mucosal injury, often including nocturnal episodes |
|
What is the presentation for GERD?
|
"Heartburn" (pyrosis) - can mimic angina
Precipitated by meals or laying down (can awaken pt from sleep) Odynophagia and/or dysphagia Regurgitation, nausea, globus sensation Water brash (acidic/sour taste in mouth) PE: mostly unremarkable, may have epigastric pain |
|
How is GERD diagnosed?
|
Not necessary or practical to initiate a diagnostic evaluation in every pt with heartburn
Can put them on meds and see if get better; see them back in a few weeks Potential studies: endoscopy, esophageal manometry, ambulatory esophageal pH monitoring |
|
When do you do endoscopy for a case of GERD?
|
Endoscopy with biopsy should be done at presentation for patients with troublesome dysphagia
Should also be done to evaluate pts with suspected GERD who have not responded to empiric trial of twice daily PPI therapy |
|
When is esophageal manometry done in a case of GERD and why?
|
Pts with suspected GERD, not responded to empiric trial of twice daily PPI therapy and have normal findings on endoscopy
Allows for evaluation of LES pressure and muscle contractions of esophagus |
|
When is ambulatory esophageal pH monitoring done for GERD and what does it do?
|
Pts with suspected GERD, not responded to PPI, normal endoscopy, no major abnormality on manometry
Trans-nasally placed catheter or wireless, capsule shaped device affixed to distal esophageal mucosa (trans-nasal 24 hrs, wireless 48-96 hrs) Monitors percentage of time esophageal pH is below 4 |
|
What is the treatment for GERD?
|
Mild symptomatic GERD managed empirically
Lifestyle modifications Antacids Histamine-2 receptor antagonists Proton pump inhibitor (PPI) - treat for 8-12 weeks Surgery (Nissen fundoplication) - tighten LES |
|
What lifestyle modifications can be made for someone with GERD?
|
Avoidance of foods that may precipitate reflux (coffee, alcohol, chocolate, fatty foods)
Avoidance of acidic foods may precipitate heartburn (citrus, carbonated drinks, spicy foods) Adoption of behaviors that may reduce esophageal acid exposure (weight loss, smoking cessation, elevating head of bed, avoid laying down 2-3 hrs after meals) |
|
What is Barrett's esophagus?
|
Complication of GERD
Columnar epithelium replaces stratified squamous epithelium that normally lines distal esophagus (more resistant to acid) Predisposes to development of adenocarcinoma of esophagus |
|
What is the presentation of Barrett's?
|
Most pts seen initially for GERD symptoms (columnar metaplasia causes no symptoms)
Ulceration, stricture formation, bleeding PE: similar to GERD |
|
How is Barrett's diagnosed?
|
EGD with biopsy
Squamocolumnar junction and gastroesophageal junction Columnar epithelium has reddish color and velvet-like texture on endoscopic exam, squamous has pale, glossy appearance |
|
How is Barrett's managed?
|
Treatment of associated GERD - initial therapy with PPI
Endoscopic surveillance to detect dysplasia - suggested in pts with multiple risk factors associated with esophageal adenocarcinoma (50 years or older, male, white, chronic GERD, hiatal hernia, elevated BMI, or intra-abdominal distribution of body fat) |
|
How often should endoscopic surveillance be done to detect dysplasia in Barrett's?
|
No dysplasia: 3-5 years
Low-grade dysplasia: 6-12 months High-grade dysplasia: 3 months |
|
What is peptic ulcer disease?
|
General term for defects in GI mucosa caused by HCl and pepsin in gastric juice (esophagus, stomach, or duodenum)
Associated with H. pylori infection and ingestion of NSAIDS including aspirin Risk factors: alcohol abuse, stress (physical or emotional), smoking, radiation therapy |
|
What is the presentation for peptic ulcer disease?
|
Can be asymptomatic until complications occur
Nausea Early satiety Abdominal pain - burning hunger-like empty feeling; immediately with meals (gastric); 2-5 hrs after meals (duodenal); nocturnal symptoms b/w 11-2 that wake pt; relieved with alkali, food, or antisecretory agent PE: wight loss, epigastric abdominal pain |

Antisecretory therapy for all PUD pts (H2 blockers, PPI)
Eradicate H. pylori (PPI, amoxicillin, clarithromycin for 7-14 days) Avoidance (remove aggravants) Confirm eradication of infection in all pts 4-6 weeks after treatment (urea breath testing, stool antigen, endoscopy) |
|
What is Zollinger-Ellison syndrome?
|
Ulceration of upper jejunum, hypersecretion of gastric acid, and non-beta islet cell tumors of pancreas "gastrinomas"
Gastrin identified as agent responsible for syndrome 90% of pts with ZES develop peptic ulcers - solitary ulcers less than 1cm, frequently recurrent, 1st part of duodenum most common (also distal duodenum and 1st part jejunum) |
