epigastric pain/disconfort
nasuea and vomiting
dyspepsia- heart burn, reflux, bloating, belching= indigestion

gastric ulcer
what investigfations for peptic ulcer
endoscopy is diagnositic
rapid urease test- CLO = see if h.pylori
biopsy when there to see if cancerous not ulcer as look similar
management of peptic ulcer
like gord
ppi strong one
if got h.pylori then 7 day regime of ppi and amoxicillin and either clarithromycin or metronidazole twice daily
if allergic to pennicillin have metronidazole and clarithromycin
lifestyle adives
risk factrs for deeloping peptic ulcer
h.pylori infection
stress, alcohol, smoking

nsaids
asprin
bisphosphnates
potassium supllements
ssri
recreational drugs
zollinger ellison syndrome
complications of peptic ulcers
bleeding from ulcer- can be life threatening
perforation=> acute abdomen and peritonitits
scarring and stricture= pyloric stenosis = hard for food to empty out of stomach = upper abdo pain, nasuea and vomiting worse after eating and ditention
patient had a peptic ulcer then took ppi for it. they they found they got full quickly and were vomiting and abdo pain worse after eating. what is this complicartion
pyloric stenosis
whats gord
acid from stomach refluxes throgh lower oesopahgeal spincter and irritaes lining of oesopahgus
whats dyspesia
comples of upper gi symtoms thats typically there for at least 4 weeks
= feeling of indegestion
signs and symtpoms of gord/ covers dyspesia
heart burnacid regurgitation
retrosternal/epigastric pain bloating
nasuea and vomiting
noctunral cough
hoarse voice
asthma affected
dental erosions
risk factros for gord
obestiy tight clothing
trigger foods
smoking and alcohol coffee stress
pregnancy
drugs that lower oesphageal spincter pressure= CCB, anticholinergics, theophylline, benzodizapines, nitrates
pt comes with gord symptoms. what do you do
offer h.pylori test
if not wanting test give ppi for 4 weeks
if oesphagitis then 8 weeks
lifestyle advice
when would you refer a patient with gord symptoms for an endoscopy
restiant to treatment
pt doesnt want long term medication which is needed
firsk factors of barrets
dysphagia = red flag 2ww
weight loss
over 55= 2ww
upoer abdo pain and relfux
nasuea and vomitng
low hb
high platelet count
treatment for gord
lifestyle advice= use pillow at night eat smaller lighter meals
weight loss
decrease tea, coffee, alcholol
avoid heay melas before bed
sit up after a meal
avoid triggers
acid neutralising med when needed= gaviscon, rennie

ranitidine= h2 r antagonist - alternative to ppi
surgery= laproscopic fundoplication= wrap fundus around lower pesopageal sphincter
h.pylori test
what h.pylori test are there and how does h.pylori damage stomach
burrows through mucosa to avoid acidic enviroment which exposes wppithelial cells to gastric acid
h.pylori produces urease which converts urea to ammonia to reduce acid envirmoment. ammonia dmaages the epithelial cells
urea breath test with carbon 13
stool antigen test
rapid urease test - done in edocscopy. get biopsy
how to treat gord with h.pylori present
triple therpay fr 7 daysppi + amoxicllin + clarithromycin or metronidazole
what type of bactieria is h.pylori
gram negative aerobic
whats barrets oesopahgus
metaplasia
squamous-> columnar
symtpoms will subside moramlly when this happens
goes from columnar with no dysplasia to low grade dysplasia to high grade dysplasia to adenocarcinoma of oesopahgus
treat barrets
like gord =
ppi or if low grade or high grade dysplasia can do ablation therpay to kill the cells and allow new ones to form= cyrotherpay/ laser therpay/ photodynamic therapy
casues of upper gi bleed
mallory weiss tear
oesopaheal varices
peptic ulcer
stomach/duodenal cancer
pt jaundice
low hb
high urea
oesophgeal varices due to liver disease
s and s of upper gi bleed
haemetemsis
coffee ground vomit
meleana
haemodynamically unstable= low bp, tachycardia
low hb
high urea
syncopy
may hae symptoms of underlying pathologu
jaundice= liver disease causing oesophageal varices
epigastric pain and dyspesisa= peptic ulcer
