Abstract:
Objective To explore the images and diagnostic evaluation of X-ray combined with ultrasound in paralytic intestinal obstruction caused by antipsychotic agents. Methods The data of X-ray and ultrasound of 124 cases of clinically diagnosed paralytic intestinal obstruction caused by antipsychotic agents were analyzed retrospectively, as well as their rates of confirmed diagnosis. All the 124 patients were examined by erect abdominal radiography and fluoroscopy,68 of the 124 patients by ultrasound. Results According to their typical images,the rate of X-ray confirmed diagnosis was 87.9%(109/124) with 15 missed diagnosis and the rate of missed diagnosis was 12.1%( 15/124);the rate of ultrasound confirmed diagnosis was 82.4%(56/68) with 12 missed diagnosis and the rate of missed diagnosis was 17.6%(12/68). There was no significant difference between X-ray and ultrasound (P＞ 0.05 ). Compared with X-ray or ultrasound ,X-ray combined with ultrasound in the diagnosis of paralytic intestinal obstruction could increase the rate of confirmed diagnosis (100.0% ,68/68),and decrease the rate of missed diagnosis (0),the difference was statistically significant (P＜ 0.05 ). Conclusions X-ray examination is the first choice to diagnose paralytic intestinal obstruction caused by antipsychotic agents,but ultrasound has the advantage of finding fluid in abdominal cavity. To reduce missed diagnosis, X-ray should be combined with ultrasound.
