(5) Interestingly, experimental bowel obstructions in animal models showed that the necrotic intestinal epithelium of strangulated obstruction releases amylase.
Observations of the blood amylase levels in the dog with experimentally produced simple and strangulated obstructions of the small intestine.
Another study reported that patients with strangulated obstruction have 2 to 10 times higher rates of death than those with nonstrangulated obstruction [5, 6].
In contrast, body temperature [greater than or equal to] 38.0[degrees]C was associated with a 3.8-fold increased risk of strangulated obstruction. Positive peritoneal irritation sign was associated with a 34-fold increased risk of strangulated obstruction.
