Abstract:
Objective To analyze the causes of missed diagnosis and misdiagnosis of abdominal organ le -sions through reviewing preoperative transabdominal ultrasound reports .Methods Data of the patients who re-ceived abdominal operation for abdominal organ lesions ( including liver , gallbladder , biliary tract , pancreas , spleen, kidney, adrenal gland, and appendix) in Peking Union Medical College Hospital within the period from March 1 to August 31 in 2013 were exported from pathological workstation .The preoperative ultrasound reports of these patients were reviewed .The missed diagnosis and misdiagnosis cases were recorded , and causes of the mis-takes were analyzed .Results Altogether 58 cases of missed diagnosis or misdiagnosis were identified from 1081 ultrasound reports (5.37%, 58/1081), including 6 liver lesions (5.77%, 6/104, all misdiagnosed), 6 gall-bladder and biliary tract lesions ( 1.30%, 6/462 , 5 missed and 1 misdiagnosed ) , 14 pancreatic lesions (19.72%, 14/71, all missed), 20 kidney and adrenal lesions (6.47%, 20/309, 11 missed and 9 misdiag-nosed), and 12 appendical lesions (16.00%, 12/75, 11 missed and 1 misdiagnosed).The average maximum diameter of the missed nodular lesions was significantly smaller than that of the misdiagnosed lesions ( P =0.001 ) .Conclusions Missed diagnosis and misdiagnosis of ultrasound are attributable to various causes , inclu-ding the nature , location , and size of abdominal organ lesions and the limitation of transabdominal ultrasound technology .The clinical ultrasound examination should be carried out very carefully and thoroughly .Ultrasound radiologists should have a thorough understanding of characteristics of different organ lesions and the limitation of ultrasound technique , in order to avoid missed diagnosis and misdiagnosis in clinical practice .
