Q

Esophageal cancer

-correlation between the damage of esophagus wall and dysphagia

A
  • more than 50% damage = transitory dysphagia
  • less than 10mm damage = stable dysphagia - hard to swallow solid
  • less than 5mm damage = stable dysphagia - hard to swallow liquids

Q

Esophageal cancer

-most common surgical procedures (4)

A
  • Ivor-Lewis - intrathoracic anastomosis –> if the tumor is at the level of the azygous vein
  • Mckeown - anastomosis in the neck –> if the tumor is above the level of the azygous vein
  • Orringer - trans-Hiatal approach –> only incision in the neck, NOT RECOMMENDED if spread to the lymph nodes
  • Esophagectomy through left thoracophrenolaparatomy –> not recommended, trauma is too big

Q

Best organ to replace the esophagus

A

stomach
small intestine
colon

17
Q

Esophageal cancer

-palliative care (3)

A
  • ablation - electrocoagulation, laser
  • dilatation - stenting
  • non-endoscopic procedures - surgery, chemo, radiotherapy
18
Q

Benign tumors of the esophagus

  • Leiomyoma (3)
  • GIST (3)
  • Lipoma (4)
A
  • most common, lower part, usually causes no symptoms
  • biopsy is recommended, wider resection, biological therapy: tyrosine kinase inhibitors
  • rare, upper part, increases with peristalsis (overtime), recommended to be removed because aspiration risk is high if patient is vomiting
19
Q

Benign tumors of the esophagus

  • Schwannoma (2)
  • Hemangioma (3)
  • Squamous cell papilloma (3)
A
  • in all layers of the wall, resection if patient has symptoms
  • blue color during endoscopy, can cause bleeding if traumatized, resection or sclerotherapy
  • small, all parts, can be resected (need to evaluate morphology first)
20
Q

Chemical burns of the esophagus

-degrees

A

I - mucosa - edema, erythema
IIa - mucosa and submucosa - hemorrhage, erosions, blisters, ulcers
IIb - mucosa + submucosa - circumferential lesions
IIIa - + muscle - ulcers
IIIb - all layers - ulcers
IV - all layers - perforation

21
Q

Esophageal strictures

  • where does it occur more often?
  • etiology
  • diagnostics
A
  • most often occurs in the sites of anatomical and physiological narrowing
  • esophagitis, caustic strictures, iatrogenic, Schatzik ring
  • x-ray with barium sulfate, endoscopy, evaluate the cause - pH metry, CT, manometry
22
Q

Esophageal strictures

-treatment (3)

A
  • esophageal dilation
  • surgery - new esophagus
  • stenting
23
Q

Esophageal strictures

-treatment –> esophageal dilation - indications (2) and disadvantages (3)

A

indications: stable dysphagia, gastroscope doesn’t fit in the esophagus
disadvantages: long treatment (procedure needs to be done many times), frequent complications, discomfort

24
Q

Esophageal strictures

-treatment - -> stenting - complications (5)

A
pain 
bleeding 
movement of the stent 
tumor grows in the stent
GERD and hearburn
25
Q

Esophageal perforation

-symptoms

A
pain swallowing 
dysphagia 
swelling of the neck
abdominal pain 
subcutaneous emphysema 

Manifestation of Boerhaave syndrome - Mackler’s triad: vomiting, chest pain that radiates to the back, subcutaneous emphysema

26
Q

Esophageal perforation

  • etiology
  • diagnosis
A

-iatrogenic, spontaneous, trauma

  • x-ray with barium sulfate –> nacler sign
  • CT
  • endoscopy
27
Q

Esophageal perforation

-treatment (5)

A

start from 0 diet, gastric relief, infusion therapy + antibiotics, nutrition, drainage

28
Q

Esophageal diverticulum

  • classification (3)
  • symptoms (2)
A

abnormal pouches that arise from the wall of the esophagus

  • Pharyngoesophageal (Zenker’s), middle esophageal, Epiphrenic (rare, grow a lot, rarely cause symptoms)
  • dysphagia, halitosis
29
Q

Esophageal diverticulum

  • location
  • diagnosis
  • treatment
A
  • between inferior constrictor and cricopharyngeus
  • barium swallow, endoscopy, esophageal manometry
  • PPI, surgery
30
Q

Esophageal achalasia

  • etiology
  • pathogenesis
A
  • unknown
  • increased basal LES pressure, incomplete relaxation of LES upon swallowing, aperistalsis
  • lack of noradrenergic, non-cholinergic, inhibitory ganglion cells –>imbalance in excitatory and inhibitor neurotransmission
  • cardiospasms
31
Q

Esophageal achalasia

  • symptoms (4)
  • diagnosis (3)
  • treatment
A
  • dysphagia, weight loss, chest pain, regurgitation
  • esophageal manometry, endoscopy, x-ray with barium sulfate
  • calcium channel blockers, long-acting nitrates, botulinum toxin
  • Heller myotomy, Dor or Toupet fundoplication esophagectomy
