Stomach🥳 Flashcards
HH definition
HERNIA - protrusion of a whole or part of an organ through the wall of the cavity that contains it into an abnormal position
HH - protrusion of an organ from the abdo cavity into the thorax through the oesophageal hiatus. typically stomach.
HH types? pic on TMS
- sliding (?%) - gastro oesophageal junction(GOJ), abdo part of oesophagus and cardia of stomach move through diaphragmatic hiatus into thorax
- rolling (?%) - upward movement of gastric fungus occurs to lie alongside a normally position GOJ creating a bubble of stomach in the thorax
HH risk factors?
- age why? inc intra abdominal pressure eg - pregnancy - obesity - ascites
HH clinical features?
- majority asymptomatic
- may experience GORD symptoms - worse in what position?
other signs & symptoms inc: - vomiting & weight loss (rare but serious - why?)
- bleeding/anaemia (2° to what?)
- hiccups or palpitations (why?)
- swallowing difficulties (why?)
HH on examination?
- typically normal
- those w v large HHs - bowel sounds may be auscultated within the chest
HH differential diagnoses?
- cardiac chest pain
- gastric & pancreatic cancer (particularly if there is evidence of what? x3)
- GORD
HH investigations?
- OGD is gold standard. shows upward displacement of of the GOJ
- incidental diagnosis on CT or MRI
- less common - contrast swallow
HH conservative managment?
- PPIs to reduce acid secretion & aid in symptom control. (when should they be taken? why?)
- lifestyle modification (eg ??)
- smoking cessation & reduced alcohol intake (what do both nicotine & alc do to LOS function?)
HH when is surgical management indicated?
- pt is remaining symptomatic, despite mac medical therapy
- inc risk of strangulation/volvulus (rolling/mixed type HH) (obstruction suspected? what should happen prior to surgery???)
- nutritional failure (why does this happen?)
HH surgical management options?
- cruroplasty - what is this?
- fundoplication - what is this?
HH surgical management complications?
despite good success rate (?%) comps include:
- recurrence of hernia
- abdo bloating (why?)
- dysphagia (why?)
- fundal necrosis (if blood supply from what artery has been disrupted?) surgical emergency!! - requires major gastric resection
HH complications?
- prone to incarceration & strangulation (what type is more prone?)
- gastric volvulus - stomach twists on itself by 180° so gastric passage is obstructed leading to tissue necrosis. presents w Borchardt’s triad (what is this?)
PUD peptic ulcer definition?
a break in the lining of the GI tract extending through the muscularis mucosae of the bowel wall. an endoscopic diagnosis.
- where are they most commonly located?
PUD aetiology?
- Gi mucosas normal defense mechanisms? x2
- PUD occurs when there is an imbalance between factors that protect the mucosa of the stomach & duodenum & factors that cause damage to it
PUD risk factors?
- H pylori - how does it inc risk?
- NSAID use? - how does it inc risk?
- corticosteroid use (in conjuction w what?)
- prev gastric bypass surgery
- physiological stress (eg??? x2)
- zollinger-ellison syndrome
