Diffuse esophageal spasm: sx/sx | anterior nonexertional CP (unrelated to eating); simultaneous, nonperistaltic contractions of esophagus; usually self-limited |
Diffuse esophageal spasm dx | Barium Esophagography: corkscrew or rosary-bead contraction below aortic arch; manometry: large amplitude intermittent simultaneous contractions |
Most common connective tissue disorder involving the esophagus: | Scleroderma esophagus (atrophy & fibrosis of esophageal smooth mx) |
Scleroderma esophagus: Dx findings: | Barium esophagography: patulous LES with free reflux; manometry: low amplitude/absent LES pressure; upper endoscopy detects Barrett or peptic stricture |
Esophageal ca: presentation | Progressive solid food dysphagia, weight loss |
Esophageal ca eval | CXR (mediastinal widening, lung or bony mets); barium esophagram (polypoid, infiltrative, or ulcerative lesion); EGD w/ bx (gold standard); Chest CT/EUS for staging |
Esoph ca: tx | mainstay: surg resection (complete esophagectomy); unresectable: Rtx, Ctx, endoscopic stenting for palliation |
GERD pathophysiology: | inappropriate relaxation of LES |
Drugs, etc that decrease LES tone -> GERD: | caffeine, nicotine, CCBs, nitrates, theophylline, sedatives |
Optimal study to find pathologic reflux (esp in patients with normal endoscopy result) = | Ambulatory esophageal pH monitoring |
infectious esophagitis workup = | EGD with biopsies |
Endoscopic findings suggesting candidal esophagitis: | linear or diffuse yellow-white plaques |
Endoscopic findings suggesting CMV vs HSV esophagitis: | CMV: single & multiple superficial ulcers; HSV: deep ulcers |
CMV esophagitis tx = | IV ganciclovir (if not tolerated: IV foscarnet) |
Common causes of pill esophagitis: | NSAIDs, iron, Abx, vitamin C, KCl, quinidine, zalcitabine, zidovudine, alendronate |
Achalasia pathophysiology: | Progressive degeneration of ganglion cells in myenteric plexus in esophageal wall & loss of inhibitory (VIP- and nitric oxide-releasing & LES-dilating) neurons. Loss of esophageal smooth mx peristalsis in distal 2/3; increased tonus of LES |
Diffuse esophageal spasm mgmt | Sx reduction. SL NTG, nitrates, CCBs may be effective; dilation w/Maloney bougies vs long myotomy if intractable |
