Q

Dx of esopahgeal carcinoma?

A

Non specific lab findings

Barium swallow to asses dysphagia

EGD establishes dx…

69
Q

Tx of esophageal carcinoma?

A

Depends on staging… usually involves combo of surgery/chemo/rad

(poor prognosis)

70
Q

How do you confirm the Dx of achalasia?

A

Esophageal Manometry

71
Q

Barium esophagography discloses characteristic findings, including esophageal dilation, loss of esophageal peristalsis, poor esophageal emptying, and a smooth, symmetric “bird’s beak” tapering of the distal esophagus.

What do we do next?

A

After esophagography, endoscopy is always performed to evaluate the distal esophagus and GEJ to exclude a distal stricture or a submucosal infiltrating carcinoma. The diagnosis is CONFIRMED by esophageal manometry.

72
Q

what is esophageal manometry? What does it confirm?

A

Manometry will indicate how well the esophagus can perform peristalsis. Manometry also allows the doctor to examine the muscular valve connecting the esophagus with the stomach, called the lower esophageal sphincter, or LES.

Confirms the dx of achalasia

73
Q

which study would I do on the esophagus to measure pH continuously for 24-48 hours?

A

Esophageal pH recording and Impedance Testing

Great for measuring acid reflux, but not nonacid reflux.
