Q

T/F: Treatment for achalasia relieves the obsturction and corrects the peristaltic deficiency of the esophagus.

A

False - all treatments are palliative. They relieve the obstruction but cannot correct the peristaltic deficiency of the esophagus

Q

What are invasive treatments for Achalasia?

Study These Flashcards
A

Endoscopic botulinum toxin injection, pneumatic dilation, lap Heller myotomy, per oral endoscopic myotomy

23
Q

Are those with achalasia considered full stomachs?

24
Q

In what disease does the dilated esophagus retain food for many days?

Study These Flashcards
A

Achalasia - therefore the duration of fasting is meaningless

25
In what patient population does distal esophageal spasm typically occur?
eldelry patients
26
What causes distal esophageal spasm?
ANS dysfunction
27
What does an esophagram show in a patient with distal esophageal spasm?
Corkscrew or rosary bead esophagus
28
pain produced by distal esophageal spasm can sometimes mimic _____
angina pectoris
29
What medications reduce pain associated with distal esophageal spasm?
Nitroglycerin, Traxodone and Imipramine (both antidepressants), and Sildenafil (phosphodiesterase inhibitor)
30
What are esophgeal diverticular?
Outpouching of the wall of hte esophagus
31
What location does Zenker's diverticulum occur? pharyngoesophageal, mideosphageal, or epiphrenic?
Pharyngoesophageal
32
What S/S occur with small-medium sized Zenker's diverticula?
asymptomatic
33
_____ appears in a natural zone of weakness in the posterior hypopharyngeal wall and can cause significant bad breath from retention of food.
Zenker's diverticulum
34
T/F: Zenker's diverticular can comrpess the esophagus.
True - if they become large and filled with fluid... this leads to dysphagia
35
How is anesthesia induced in esophageal diverticula?
Head-up position WITHOUT cricoid pressure (b/c cricoiod pressure reducing the risk of aspiration during RSI is doubtful in this case)
36
T/F: An NGT is used to decompress esophagus and abomdne after induction in esophageal diverticula?
False - insertion of a NGT is avoided b/c it can perf the diverticulum
37
A _____ is a herniation of part of the stomach into the thoracic cvity through the _______ in the diaphragm.
hiatal hernia; esophageal hiatus
38
How does esophageal cancer present?
With progressive dysphagis to solid food and weight loss
39
What are post-op complications of esophagectomy
ARDS, anastomotic leaks, dumping syndrome, esophageal stricture
40
What risk persists for life after esophagectomy?
Significant risk of aspiration
41
What are the most common S/S of GERD?
heratburn and regurgitaiton
42
What are natural antireflux mechanisms? (3)
1. LES 2. crural diaphragm 3. anatomic location of the GE junction below the diaphgramatic hiatus
43
At rest, the ___ exerts a high pressure that prevents gastric contents from entering esophagus.
LES
44
What is the average resting tone of the LES in patients wtihout GERD?
29 mmHg
45
What is the average resting tone of the LES in patients with GERD?
13 mmHg
46
What are 3 common physiologic causes of GERD?
1. transient LES relaxation 2. LES hypotension 3. anatomic distortion of the GE junction
47
What is therapy for GERD?
lifestyle modificaiton
48
What foods should be avoided with GERD?
Ones that reduce LES tone (fatty & fried, alcohol, peppermint, chocolate) and acidic foods (citrus and tomato)
49
Which is more effective for GERD to inhibit gastric acid secretion: PPI or H2 blockers?
PPI
50
What is a surgical option for severe GERD?
Nissen fundoplication
51
Cimetidine effect begins in _____
1-1.5 hours
52
What are the MOA of cimetidine and ranitidine?
decrease gastric acid secretion and increase gastric pH
53
What isthe DOA of cimetidine?
3 hour
54
Is ranitidine or cimetidine more potent?
Ranitdine
