17
Q

What else can you do [2]

A

Barium swallow - used for motility but may pick up

EUS with CT / MRI

18
Q

Staging investigations [4]

A
FBC, LFT
CT CAP (chest, abdo, pelvis)
MRI
Laparoscopy if suspicion of peritoneal spread 
Bone scan
19
Q

What do you do if laparotomy -ve

A

PET

If primary does not light up then no mets will

20
Q

How do you treat dysplasia

A

Endoscopic ablation

21
Q

Management T1a [3]

Can this be applied to T1b? [2]

A

Endoscopic mucosal resection - Can’t do for 1b as Mucosa won’t separate from sub-mucosa

22
Q

Management T1b / T2 [3]

A

Neoadjuvant Chemo
Surgical oesophagostomy
Radical RT / chemo

23
Q

What is only curative for Adenocarcinoma

A

Surgery

24
Q

What are complications of bariatric surgery [5]

A
DVT / PE
Infection
Malnutrition 
Vitamin deficinecy
Hair loss
25
Q

Rationale for neoadjuvant chemo

A

Most upper GI presents with mets

26
Q

What do you do for palliation [6]

A
Stent
Laser
PEG, Nutrition
Intubation
Chemo / RT
27
Q

What do you do if there’s Plummer Vinson [2]

A

Iron supplement

Dilatation of web

28
Q

What are complications of surgery [6]

A
Chronic volume reflux 
Anastomotic leak = mediastinitis
Arrhythmia
Lose LOS - small meals often
Perforation
General risks
29
Q

What do you get after op

A

Feeding jejunostomy to allow time to heal

30
Q

Pathogenesis of gastric cancer [4]

A

Gastritis
Intestinal metaplasia
Dysplasia
Cancer

31
Q

What causes

A

H.ployri

Unknown

32
Q

What are the RF of gastric cancer [9]

A
Male, >55
Smoking
H.pylori  > atrophic gastritis
Gastritis, Reflux, Ulcer
Previous gastric resection
Blood group A
Pernicious anaemia > atrophic gastritis
Low SEC, High nitrate diet
Familial syndromes eg E cadherin abnormality
33

  • Dysphagia
  • N+V, bloating, early satiety
  • Malaena
  • Anemic symptoms

Signs

  • Epigastric mass
  • Jaundice, hepatomegaly
  • Ascites
  • Virchow’s node
  • Acanthosis nigricans
34
Q

How does gastric cancer spread [3]

A

Direct - within stomach, pancreas
Lymphatic - Virchow’s node
Blood to liver
Trans-colemic within peritoneal cavity - ovaries, umbilical

35
Q

What is 1st line investigation [2]

A

Endoscopy + biopsy

+/- Barium swallow

Q

How do you treat [3]

A

Neo-adjuvant chemo
Endoscopic resection if early stage
Gastrectomy with Roux-en-Y to prevent bile reflux

38

Ax [2]
Px [2]
Sxs [4]
Ix [2]
Mx [2]
A

Ax: gastrinoma in small intestine or pancreas, mostly malignant, assoc with MEN1
Px: gastrin increases HCl causing peptic ulceration and chronic diarrhea
Sxs: abdo pain, dyspepsia, steatorrhea, refractory ulcers
Ix: stomach pH <2, MRI/CT
Mx: high dose PPI, surgical resection
