Q

Esophageal cancer treatment options (3) and prognosis

A
  • endoscopic mucosal resection (stage T1a)
  • esophagectomy with lymphadenectomy (stage T1b)
  • most of time palliative chemo, stents, brachytherapy, etc.

5 year survival rate only about 50% even without metastasis

Q

Eosinophilic esophagitis and presentation

A

Chronic inflammation due to allergic process resulting in increased eosinophils in esophageal tissue, presents with reflux symptoms, solid food dysphagia, and impactation of food bolus, symptoms do NOT improve with acid suppression**

Q

Eosinophilic esophagitis diagnosis (3)

A
  • EGD with esophageal biopsy with pathology report showing >15 eosinophils per hpf not otherwise explained
  • eosinophilia persists after trial of PPI
  • characteristic tears on endoscopy

Q

Esohpageal rings

A

Concentric ring protruding into lumen that is typically in the distal esophagus and asymptmatic mostly but sometimes causees intermittent dysphagia for solids esp when the tube become <13 mm in diameter***

16
Q

Esophageal webs and rings treatment options (3)

A
  • rupture during EGD
  • bougie dilation
  • PPI daily x6 weeks
17
Q

Zenker diverticulum and gold standard diagnosis (1) and treatment (1)

A
  • Herniation of esophageal mucosa, rare typically in elderly populations who regurgitate undigested food stuffs
  • barium swallow
  • surgical technique if necessary
18
Q

Nutcracker esophagus or hypertensive LES

A

Hypercontractility of the esophagus

19
Q

Ineffective esophageal motility or hypotensive LES

A

Hypocontractility of the esophagus

20
Q

Diffuse esophageal spasm (DES)

A

Discoordinated motility of the esophagus, can cause chest pain

21
Q

Esoophageal motility disorders diagnostic studies (3)

A
  • barium swallow
  • EGD to rule out structural cause
  • esophageal manometry
22
Q

Up to __% of scleroderma patients with have esophageal involvement, resulting in…

A

90%, resulting in atrophy, sclerosis, absent peristalsis

23
Q

Achalasia

A

Inadequate peristalsis in the lower esophagus due to a tight lower esophageal sphincter that leads to progressive dysphagia for solids and liquids***

24
Q

Achalasia diagnostic studies (2)

A
  • bird beak sign on barium esophogram

- EGD

25
Q

Achalasia treatment options (3)

A
  • surgical myotomy
  • pneumatic dilation of LES (risky and loses efficacy over time)
  • botox injections
26
Q

Functional dysphagia

A

Sense of food lodging/sticking in esophagus with no evidence of cause, not many treatment options other than lifestyle change

27
Q

Odynophagia

A

Painful swallowing, often medication induced esophagitis, pill becomes lodged and causes mucosal injury, can also be infectious

28
Q

GERD

A

Reflux with or without mucosal injury, very very common

29
Q

Alarm symptoms with GERD that indicate need for EGD to check for barrett’s esophagus (3)

A
  • GI bleed
  • new onset dyspepsia >60
  • unexplained weight loss
30
Q

GERD treatment options (step up therapy)

A

Step up from bottom

  • Lifestyle mods
  • PRN H2 blockers
  • H2 blocker daily
  • PPI gradual increase

-antacids and sucrlfate should be used prn for mild symptoms and pregnancy but not otherwise

31
Q

Refractory GERD

A

GERD that has no response to once daily PPI therapy

32
Q

Barrett’s esophagus

A

REplacement of stratified squamous epithelium in distal esophagus with metaplastic columnar epithelium, increases risk for esophageal cancer more than 30 fold, with short segment being more prevalent but long segment causing more severe reflux and risk for cancer

33
Q

Barrett’s esophagus diagnosis (1)

A

Endoscopy with biopsy

34
Q

Barrett’s esophagus screening

A
  • no recommendation on screening in females

- only recommended if multiple risk factors exist

35
Q

Barrett’s esophagus treatment options (3)

A
  • indefinite PPI therapy
  • ongoing surveillance
  • radiofrequency ablation
36
Q

Benign lesions of esophagus

A
  • schwannomas (rare, typically present with dysphagia
  • hemangiomas (rare incidental finding)
  • glycogen acanthosis (uniform, celiac dz)
  • esophagitis dissecans superficialis (sloughing entire mucosal epithelium)
37
Q

Caustic esophageal injury common ingestions (4), what 2 things do you always do and what 2 do you NOT do?

A
  • battery liquid
  • drain cleaner
  • hair relaxers
  • bleaches

Preserve the airway and get a chest x ray, Do not induce vomiting this will cause more injury, do not do endoscopy if more than 24 hours to prevent perforation

38
Q

Alkaline vs acidic caustic esophageal injury

A

Liequefactive necrosis with severe injury rapidly vs coagulation necrosis more limiting
