[A case of nonocclusive mesenteric ischemia (NOMI) which occurred in a patient with torsion of gallbladder].

We report a case of nonocclusive mesenteric ischemia (NOMI) which occurred in a patient with torsion of gallbladder. A 91-year-old woman was admitted to the hospital and was diagnosed of acute cholecystitis. The next day, she went into shock. Then, we diagnosed her illness as torsion of gallbladder by computed tomography and ultrasonography, and performed an emergency operation. After cholecystectomy, it was recognized that the wide range of the small intestine had become necrotic sporadically. We diagnosed it as NOMI, and performed the wide resection of the small intestine followed by making double stomas. There is no previous report of NOMI associated with torsion of gallbladder. We guess the cause of NOMI in this case would be dehydration because of gallbladder torsion. NOMI has high mortality. Early diagnosis and early treatment are of great importance in NOMI.
