Small Bowel Disease Flashcards
describe the pathology of appendicitis
- lumen may or may not be occluded
- mucosal inflammation
- lymphoid hyperplasia
- obstruction
- build up of mucus and exudate
- venous obstruction
- perforation
describe the clinical diagnosis of appendicitis
- central pain that migrates to RIF
- anorexia
- nausea
- vomiting
- may not have bowel movement
- pelvic/rectal pain
signs of appendicitis
- mild pyrexia
- mild tachycardia
- localised pain in RIF
- guarding
- rebound
specific signs and tests of appendicitis
- Rosvings: pressing on left causes pain to the right
- Psoas: patients keep the right hip flexed as this lifts an inflammed appendix off the psoas
- Obturator: if appendix is touching obtrurator interus, flexing the hip and internally rotating will cause pain
