postoperative ileus

Q: All of the following may lead to prolonged postoperative ileus except?

A) Hyperkalemia 
B) Hypomagnesemia
C) Uremia 
D) Gallbladder dysfunction
E) Pancreatitis 

Answer: A

Laboratory or radiological workup should be initiated or monitored daily if postoperative ileus lasts more than 48 to 72 hours despite all appropriate measures. Various factors may lead to prolonged postoperative ileus in surgical ICU including hypokalemia, hypomagnesemia, anemia, infection (leucocytosis), ischemia (lactate elevation), renal dysfunction (uremia), gallbladder dysfunction (liver function test or ultrasound of abdomen), and pancreatitis (amylase & lipase elevation).
