hiatus hernia Flashcards
definition
Hiatus hernia is the protrusion of intra-abdominal contents through an enlarged oesophageal hiatus of the diaphragm. A hiatus hernia most commonly contains a variable portion of the stomach; less commonly, it may contain transverse colon, omentum, small bowel, or spleen, or some combination of these organs. The herniated contents are usually contained within a sac of peritoneum.
risk factors
obesity, increased intra-abdominal pressure from various conditions, and a previous hiatus operation.
symptoms
May be asymptomatic or may present with heartburn, dysphagia, odynophagia, hoarseness, asthma, shortness of breath, chest pain, anaemia or haematemesis, or some combination of these.
investigations
1st investigations:
- CXR
- upper GI series (aka upper GI or as a barium oesophagram) – MAIN INVESTIGATION
complications
obstruction, bleeding, volvulus with and without strangulation or necrosis, and Barrett’s oesophagus.
treatment
Uncomplicated sliding hiatus hernias are treated symptomatically with medical therapy (omeprazole), although some patients may select surgical therapy.
Complicated hiatus hernias (those with bleeding, volvulus, or obstruction) have a stronger indication for surgical repair (laparoscopic or open transabdominal repair +/- anti reflux procedure).
irreversible organ ischaemia/necrosis will involve surgical resection.
