- esophageal dysmotility disorder caused by DIFFUSE multiple spastic circular M. contractions via excitatory/inhibitory imbalance - Unique features: 1. COMPLETELY uncoordinated contractions 2. NL LES function 3. no high pressure on manometry 4. corkscrew esophagus 5. associated with GERD, diabetes, and stress (SX same as NS) sx: intermittent (nonprogressive) esophageal dysphagia (solids and liquids), atypical Chest pain
26
characteristics of limited scleroderma
CREST syndrome (calcinosis, Raynaulds Phenomenon, esophageal dysmotility, sclerodactyly, telangiectasia) - structural, progressive, esophageal dysphagia * *May have chronic heartburn - Key features: esophageal smooth muscle atrophy, fibrosis-->aperistalsis, microangiopathy - tx: sx control
27
characteristics mallory weiss tear
longitudinal MUCOSAL/SUBMUCOSAL tears of the GEJ due to severe retching, vommitting, vigorous coughing - associated with alcohol intoxication - sx: PAINFUL hematemesis - dx/tx: EGD *can lead to Boerhaves Syndrome
28

29
sx of esophageal varices
asymptomatic until it ruptures then PAINLESS hematemesis | *esophageal variceal bleed is the most common cause of death in cirrhosis patients
30
characteristics if esophageal web
- structural esophageal obstruction caused by protrusion of esophageal MUCOSA - usually in upper (mid/proximal) esophagus and causes oropharngyeal dysphagia, but can arise in distal esophagus and causes esophageal dysphagia * *(Structural (solids), intermittent, non progressive dysphagia )** - can be congenital or acquired via plummer vinson syndrome or eosinophilic esophagitis * *INCREASES RISK OF esophageal SCC dx: barium swallow tx: dilatation

39
risk factors of esophageal SCC
- alcohol/ tabacco - hot beverages (reason why worse in places that drink hot tea) - achalasia - esophageal web - esophageal injury (CAUSTIC ESOPHAGITIS) - tylosis (Howel Evans Syndrome) - HIV/AIDS
40
sx and complications of achalasia
sx: undigested regurgitation, nocturnal choking, substernal discomfort, adaptive food maneuvers, halitosis (if chagas = romana sign) -complications: increased risk of SCC (get EGD to rule out), if untreated it becomes SIGMOID ESOPHAGUS
41
define "pseudoachalasia"
caused by cancer invading GEJ
42
define GVHD esophagitis
- basal epithelial cell apoptosis, mucosal atrophy, submucosal fibrosis WITHOUT acute inflammatory infiltrates sx: rash, vommiting, odynophagia
43
what is Howel Evans Syndrome
tylosis - RHBDF2 mutation caused hyperkeratinosis - risk factor for esophageal SCC
44
esophageal varices two most common causes
cirrhosis of the liver due to 1. alcoholism 2. hepatic schistosomiasis (shistosoma endemic in Egypt)
45
define plummer vinson syndrome
- occurs mainly in middle aged women - iron deficiency anemia (kolionychia) , atrophic glossitis, esophageal webs, angular chelitis (Plummer Vinson is A GEeK who hits on middle aged women )
