Q

When is anti-reflux surgery recommended in GERD?

A

Recommended for patients who responded to PPI but are intolerant of PPI or does not want long term PPI mgmt.

Prior to surgery Manometry is performed to rule out impaired peristalsis if that’s positive fundoplication is C/I; If patient does not have erosive esophagitis (EGD not showing any erosions) then prep ambulatory pH monitoring is needed.

Q

What does Manometry show in Esophageal Spasm

What does Manometry show in Nutcracker esophagus

What does Manometry show in Scleroderma

A

=Esophageal Spasm shows Simultaneous contractions with wet swallow along with intermittent normal peristalsis

  • Nutcrackers shows high amplitude contractions
  • Scleroderma you have no peristalsis and hypotension (decrease)LES leading to severe GERD (because of no peristalsis Reglan can be used in these patients)
18
Q

What are the 2 types of esophageal cancer and their location and risk factors?

A
  1. Adenocarcinoma (MC)
    Involves Distal 1/3
    risk Factors: GERD, Barret’s Smoking
  2. SCC
    Involves proximal 2/3
    Risk factors: Smoking, Alcohol, HPV, corrosive injury, zinc and selenium deficiency, Tylesosis (hyperkeratosis of palm and soles)
19
Q

What is the typical presentation of Eosinophilic esophagitis?

WhAT DOES EGD SHOWS?

A

Pt with history of Atopy plus solid Dyshagia requiring disimpaction with EGD

EGD Shows: Esophageal concentric rings, white specks, friable mucosa, linear tears with minimal trauma

Bx: Eosinophilic infiltration >15 sos/her

20
Q

What are 3 conditions in which we see isolated esophageal eosinophilia?

A
  1. Eosinophilic Esophagitis
  2. GERD (usually < 5eos/hpf)
  3. PPI responsive esophageal eosinophilia

So because of these disorders whenever eosinophilia is seen treatment is 8 weeks of BID dose PPI then repeat EGD if symptoms and eosinophilia resolve then the diagnosis is GERD or PPR responsive esophageal eosinophilia. If no improvement then its Eosinophilic esophagitis

21
Q

How is Eosinophilic esophagitis treated?

A

Swallowed steroids or viscous budesonide should show response in <1 week

22
Q

What is the definition of Dyspepsia?

What is the guideline for mgmt of new onset dyspepsia?

A

Predominantly epigastric pain lasting for at least 1 year

Age:
>60 Get EGD
<60 Test and Treat (EGD is not recommended for pure dyspepsia if < 60, pure dyspepsia mean no dysphasia,weight loss, epigastric pain radiating to the back)

  • H.Pylori positive—> treat
  • H.Pylori negative—->or treatment of h.pylori doesn’t relive symptoms treat with PPI for 8 weeks

IF no relief after 8 weeks give Reglan for no more than 12 weeks or Amitriptylene

If still no improvement psychotherapy

23
Q

When is EGD recommended for Patients <60 with dyspepsia

A

> 1 Alarm Symptoms

Or

Severe Alarm symptoms

OR

Family history of gastric cancer

24
Q

Diagnosing H.Pylori

A
  • Stools antigen test can be used for both initial diagnosis and confirming eradication (Patients taking PPI or bisthmuth cant be treated for stool antigen)
  • Urea breath test= same as above plus antibiotic

If patients on PPI, Bistmuth, Antibiotic then initial test is Serology but that should not be used to confirm eradication

25
Q

Treatment of H.Pylori

A
  1. Clarithromycin + Amoxiciliin (Flagyl if allergic)+ PPI
  2. Tetracycline+ Flagyl + PPI + Bistmuth
  3. Clarithromycin + Amox + Flagyl + PPI

14 day treatment is recommended

Choose a different antibiotic if previous macro life exposure or >15% macro life resistance)

Once the treatment regimen is concluded the next step is Ulcer healing Therapy:
For Duodenal ulcers: PPI for 4 weeks or H2 for 8 Weeks
For Gastric Ulcers: PPI for 8 weeks or H2 for 12 weeks

26
Q

What are the reasons for failure to heal of PUD?

A
  1. Noncompliance
  2. Smoking
  3. NSAID use
  4. Acid hypersecretion: ZES, Cancer
27
Q

What is the indication for maintenance (half dose H2 or PPI)for ulcers

A
  1. H. Pylori positive PUD with unsuccessful eradication
  2. H. Pylori negative ulcers with >3 recurrences per year
  3. Complications such as bleeding or perforation
28
Q

How is Gastric MALT lymphoma treated?

A

Stage I disease can have complete remission with antibiotics

Patients with ulcers, mass, submucosal or serosal disease or LN involvement need to be treated with traditional gastric lymphoma chemotherapy.

29
Q

What are the risk factors for NSAID induced Ulcer?

Does Celecoxib plus NSAID GI Protective?

Should patients be tested for h.pylori before starting NSAIDS

A 
Age > 60
Prior Ulcer
High dose NSAIDs
NSAID+steroid
NSAID + anticoagulant

these patients can be placed on prophylactic treatment

Combining Cox 2 inhibitor Celecoxib with NSAID removes its GI protectiveness and confer the same risk

Patients should be tested for h.pylori prior to starting NSAIDS if they have prior history of PUD

30
Q

How do we manage NSAID induced PUD?

What is the gold standard NSAID induced ulcer prophylaxis?

A
  1. Stop NSAID
  2. Test and treat for H. Pylori
  3. Ulcer healing therapy with PPI or H2 blocker
    - if NSAIDS must be continued then only use PPI and not H2 blocker

Prophylaxis gold standard is Misoprostol (but not well tolerated because of diarrhea) and now Esomeprazole and Lansoprazole are approved for prophylaxis

31
Q

What are the recommendations to prevent NSAID induced ulcers?

A

Based on GI and CV risk

Low risk GI and Low risk CV= NSAID only

Low GI/ High CV= Naproxen plus PPI/Misoprostol

Moderate GI/ Low CV=NSAID plus PPI/Misoprostol
Moderate GI/ High CV= Naproxen plus PPI/Misoprostol

High GI risk/Low CV risk= Cox 2 plus PPI/Misoprostol
High and High= Avoid NSAIDs and Cox 2

32
Q

When should we suspect ZES?

A 
PUD + Diarrhea
PUD + Hypercalcemia
PUD unrelated to NSAID or H.Pylori
REcurrent ulcers
Postbulbar duodenal ulcer
Nonhealing ulcers
Multiple ulcers
Fhx of PUD
Fhx MEN1
Enlarged rural fold of stomach with dilated duodenum (acid hypersecretion)
33
Q

How is ZES diagnosed? And Treated?

A

First check Gastrin level (>1000 picograms)plus evidence of acid hypersecretion (define as >15 mEq/hour or low gastric pH)because normally high acid should suppress gastrin

If gastrin is <1000 with evidence of acid hypersecretion the next step is secretin stimulation test

Once diagnosed next thing is imaging with octreotide scan

If surgical candidate then surgery if unresectable then high dose PPI and chemo

34
Q

What are the risk factors for stress ulcer prophylaxis?

A 
Coagulopathy
Mechanical ventilation for 48 hours or more
CNS Trauma
Burn
Organ transplant
Patients with history of PUD

Aim is to keep gastric pH >4

35
Q

What is the Gold standard for diagnosing Gastroparesis?

How is it treated?

A

Solid Phase Gastric Emptying

EGD is performed to rule out obstruction

Note: EGD showing residual food in stomach after overnight fast might suggests gastroparesis.

Treatment is Small, frequent, low residue meals
medical is Reglan

36
Q

GI bleed endoscopic findings?

A
  1. Actively bleeding= 55% chance of rebleed
  2. Non-Bleeding visible vessel= 43% chance or rebleed
  3. Visible clot=22%
  4. Flat pigmented spot=10%
  5. Clean base ulcer=patient can be discharged have <5% chance of rebleed
37
Q

What are the causes of nonvariceal upper GI bleed

A
  • PUD
  • Gastritis/esophagitis
  • Mallory-Weiss
  • Watermelon stomach- gastric vascular ectasia as seen in scleroderma
  • AV malformation
  • Dieulafoy lesion
  • Cancer
  • Aorta-enteric fistula
  • Cameron’s lesions (Linear erosion in patients with hiatal hernia at the diaphragm level, that may be missed on EGD leading to occult GI bleed)
38
Q

What is the antibiotic of choice for variceal bleeding

A

IV Ceftriaxone for 7 days

39
Q

What are the 2 types of GI bleed?

A

Upper (Proximal to ligament of Treitz)

  • Melena
  • Hematemesis
  • Hematochezia IF the bleed is severe and patient presents with shock

(NG tube not needed for UGIB)

Lower GI Bleed (distal to ligament of Treitz)

  • Hematochezia
  • if proximal lower GI bleed it can present as melena
40
Q

What are the causes of Lower GI bleed?

A

Diverticulosis
AV malformation
Hemorrhoid especially in a young patient
Colon Cancer

41
Q

How is GI bleed worked up?

A

Perform EGD (if negative or LGIB is suspected) Perform Colonoscopy

If Bleeding stop and Colonoscopy is negative small bowel bleeding must be ruled out with capsule endoscopy or CT enteropathy (more sensitive)

If Bleeding continues and colonoscopy is negative or cannot control bleeding send patient for RBC scan with arteriogram for embolization and surgical consult
(Note angiography can detect bleeding rate >1 ml/min)

If patient has severe bleed and colonoscopy is not possible then first step is arteriogram for emergent embolization

If patient has ongoing bleed and tagged RBC, Arteriogram are negative then rule out small bowel bleed with capsule endoscopy and consult surgery
