Clinical pathological findings in patients with intestinal volvulus tend to be non‐specific. Normal to low packed cell volumes and plasma total solids are typical. White blood cell counts are normal to elevated. Serum chemistries are often normal or have non‐specific changes associated with gastrointestinal disease [6, 9, 18]. Given the similarities in the pathophysiology of the disease process with other conditions causing vascular compromise (such as gastric dilatation and volvulus), hypokalemia with metabolic acidosis and elevated serum lactate level would be anticipated. The only reported blood gas in a case of intestinal volvulus [10] revealed a metabolic alkalosis in a pattern similar to that seen with gastrointestinal foreign bodies [10,24–26]. Coagulation profiles have not been reported in the literature associated with this disease.
