Upper GI bleeds Flashcards
Causes of upper GI bleeds [7]
Peptic ulcers
Oesophageal varices
Mallory-Weiss tear/ Boerhaave’s
Leiomyoma
Dieulafoy lesion
Gastritis/ Oesophagitis
Rockall score
Scoring tool that calculates risk of adverse events following high
Variables:
- Age
- Co-morbidity
- Diagnosis
- Shock
- Evidence of bleeding
Interpretation
- <3= good prognosis
- > 8= high risk of mortality
Glasgow-blatchford score
Assesses likelihood of medical intervention (blood transfusion/ endoscopic evaluation)
Variables: Blood urea, Hb, systolic BP, HR, melaena, syncope, heaptic disease, cardiac failure
> 6= >50% need for intervention
Acute management of upper GI bleed
- Resuscitation
- Endoscopy
- Haemostasis if active bleeding - IV PPI 72 hours
If re-bleed
- Surgical intervention–>laparotomy
- Endoscopic haemostasis
No rebleed
- H pylori eradication
- Stop NSAIDs
Balloon tamponade
- Indications
- Contraindications
- Complications
Indications
- Massive bleed, in unstable patients
- Endoscopy not available or effective
- Vasoactive agent fails.
Contraindications
- Oesophageal strictures
- Recent oesophageal or gastric surgery
Complications
- Airway obstruction
- Eoesophageal rupture
- Aspiration pneumonitis
- Pain
- Ulceration: lips, mouth, tongue.
- erosions
Surgical intervention of peptic ulcer
Over-sew of bleeding ulcer
IR embolization
- Transcatheter arterial embolisation
Emergency gastrectomy
- RARE
Stress ulcers
Reduction in mucosal blood flow
- Due to physiological stress
- Can happen in those critically ill
Duodenal vs gastric ulcer
Duodenal
Murphy’s sign
USS/ Hand pressing on RUQ and asking Pt to breathe in if painful
- Positive= localised guarding
Causes
- Acute Cholecystitis
Peptic ulcer
- Definition
- Classifications
Mucosal breach due to mucosal breakdown in stomach/ duodenum.
- Ulcer in columnar mucosa of lower oesophagus, stomach, duodenum or small bowel
Classifications
- Gastric (type 1, body and fundal)
- Duodenal and gastric (Type 3, prepyloric)
- Atypical
Gastric ulcer (type 1 ulcer)
- Risk factor
- Associations
- Symptoms
M>F= 3:1
- Age 50
Associations
- H. pylori (45%)
- NSAIDs
- Alcohol
- Smoking
- Low acid secretion
Symptoms
- Epigastric pain worse with food
- weight loss, anorexia
Duodenal/ type 2 gastric ulcer
- Risk factor
- Associations
- Symptoms
M>F= 5:1
- 25-30 years
Associations
- H.pylori (85%)
- NSAIDs
- Smoking
- High acid secretion
Duodenal symptoms
- Epigastric pain relieved by food
- Precipitated by hunger, central back radiation
- Pain is often in early hours of the morning
Atypical ulceration
- Description/ cause
- Associations
Atypical sites of gastric secretion
- Ectopic gastric mucosa in Meckel’s diverticulum
Abnormal high levels of acid secretion (Zollinger-Ellison syndrome)
Associations
- Ulcers that fail to respond to max medical therapy
- Multiple ulcers
- Ulcers in abnormal locations (distal duodenum, small bowel)
Complications of peptic ulcer
Upper GI bleed
Iron deficient anaemia
Perforation
Chronic scarring around pylorus causig gastric outlet obstruction
H. Pylori eradication therapy
Triple therapy
- Metronidazole
- Clarithromycin
- PPI
