Q

Diagnostic testing for Esophageal spasm disorders

A

Video esophogram - first step, r/o anatomic causes
Endoscopy - evaluate for anatomic or mucosal abnormalities, not helpful for spastic disorders
Manometry - gold standard to ID esophageal motor disorders, measure pressures for 24 hours.
24 hour pH Monitoring - differentiate spasm from GERD (both cause chest pain). Differentiate if dysphagia present with adequate acid suppression.

Chest and abdominal CT: staging - assess local invasion, pulmonary, LN, liver, adrenal mets
Bronchoscopy - if upper or middle third of esophagus to deteromine invasion of tracheobronchial invasion contradiction to esophagectomy

Endoscopic ultrasound - assess depth of esophageal wall invasion, regional nodal status

25
Q

29
Q

Diagnosis for stricture?

A

Barium
Endoscopy - biopsy to r/o cancer
Manometry and 24 hour pH study

30
Q

Tx stricture

A

Mechanical: Dilatation
Surgery: Esophagectomy indicated when stricture lasts > 1year or perferation

31
Q

Causes of GERD

A

​-occurs due to loss of lower esophageal sphincter resistance permitting reflux of
gastric contents into the esophagus
​-can be transient (gastric distension, increased intragastric or intraabdominal
pressure, delayed gastric emptying) or persistant.

32
Q

HPI of GERD

A

​HPI: Heartburn, dysphagia, regurgitation, chest pain, cough, hoarseness, asthma, pregnancy

33
Q

How is gastroesophageal reflux disease diagnosed?

A

​-Patients presenting for the first time with symptoms suggesting GERD may be tried on H2 blockers to see if symptoms abate.

-Failure of control of symptoms or immediate return of symptoms with cessation of therapy should prompt further workup to determine the diagnosis and severity of disease.

34
Q

How is GERD diagnosed?

A

Barium swallow: may suggest reflux
Endoscopy: early identification of complications including Barrett’s esophagus
24-hour pH study: confirm abnormal presence of acid in the esophagus
Esophageal manometry: identify features predictive of severe disease such as LES deficiency and duodenogastroesophageal reflux.

35
Q

Treatment for GERD?

A

Medical therapy: H2-blockers, Proton pump inhibitor
Surgical: manometry test to determine if enough power and esophagus to propel food. Barium swallow to exclude scarring
Nissen Fundoplication

36
Q

Name the different types of hiatal hernias

A

​Type I (sliding): leading edge of hernia at EG junction, which is displaced into the thorax, often no true hernia sac
Types II and III: paraesophageal hernias
Type II (rolling): EG junction is in normal intraabdomingal location and a hernia sac with portions of the stomach develops alongside the esophagus.
​Type III: EG junction in thorax, and hernia sac present containing parts of Stomach

37
Q

What is a hiatal hernia?

A

protrusion (or herniation) of the upper part of the stomach into the thorax through a tear or weakness in the diaphragm.

38
Q

Compare and contrast a type one hiatal hernia to a type II hiatal hernia.

A

Type I: Sliding Hiatal Hernia (accounts for 95% of cases)

STOMACH herniation located at or near the diaphragmatic opening for the ESOPHAGUS, esophageal hiatus. When the ESOPHAGOGASTRIC JUNCTION is above the DIAPHRAGM, it is called a SLIDING HIATAL HERNIA. When the ESOPHAGOGASTRIC JUNCTION is below the DIAPHRAGM, it is called a PARAESOPHAGEAL HIATAL HERNIA.

Type II: Paraesophageal Herniation
–Complication of Anti-Reflux Surgery
–Risk of gastric Volvulus (surgical emergency)
–Surgical repair is indicated if symptoms occur

39
Q

How do you diagnose a hiatal hernia?

A

​CXR: large hernia evident posterior to heart +/- air fluid level, NG tube placement prior to study can show it coiled in the intrathoracic portion of the stomach.

​Barium swallow: demonstrates the hernia, and may show poor emptying of intrathoracic portion of stomach

​Endoscopy: identify location of the EG junction, assess presence of esophagitis and evaluate degree of gastritis, assess esophageal length.
​
Esophageal manometry and 24-hr pH study: not indicated unless patient has symptoms of reflux or evidence of a motility disorder on other studies.

40
Q

Treatment for hiatal hernias?

A

Paraesophageal hernias should be repaired due to risk of strangulation or incarceration

reduction of hernia sac and contents back into the abdomen with repair of the diaphragmatic defect (primary or using a patch) and gastropexy to prevent recurrent herniation

41
Q

What are the two categories of esophageal diverticuli?

A

​-two categories: Pulsion or pseudodiverticuli and traction or true diverticuli.

42
Q

What is the most common diverticulum?

Where is it located?

When does it usually present

A

Pharyngoesophageal (Zenker’s) diverticulum

​-located posteriorly, just proximal to the cricopharyngeal muscle.
​-usually presents in the 5th to 8th decades

43
Q

What is the common history for a Zenker’s diverticulum?

A

HPI: Oropharyngeal dysphagia, spontaneous
regurgitation of undigested food and saliva, noisy swallowing, halitosis, interruption of eating and drinking by episodes of regurgitation and aspiration with or without coughing or choking, respiratory complications including hoarseness, bronchospasm, and pneumonia.

44
Q

Treatment for a Zenker’s diverticulum?

A

​Surgical: Cricopharyngial myotomy with

diverticulectomy if the diverticulum is greater than 2cm in diameter.

45
Q

Describe a traction diverticulum?

A

-usually sits in the midesophageal area
-usually secondary to a granulomatous inflammatory reaction (often histoplasmosis or tuberculosis)
​-usually are small and asymptomatic, not requiring
treatment.
​-rare complications such as fistulization to the
tracheobronchial tree or great vessels require thoracotomy, excision of the inflammatory mass, and primary closure of the esophagus and the airway or vessel.
