Abstract: Objective To investigate the diagnostic value and clinical significance of gastrointestinal barium meal retention abdominal radiography in slow transit and outlet obstructive constipation.
Methods The X-ray data of gastrointestinal barium meal retention abdomen in 95 patients with moderate and severe constipation rated by Cleveland constipation scale were analyzed retrospectively.
Results By observing the morphology of the intestine and the retention time of barium,it was found that more than 91.6% of the patients reported that the activity of the right colon was hyperactive or normal,the transverse colon was long,and the transit time of the descending colon and its distant emptying disorder was significantly prolonged.Accompanied by loss or stiffness of colonic bands and mucosal folds.
Conclusion Abdominal radiography of gastrointestinal barium meal retention has important diagnostic value in slow transit and outlet obstructive constipation,and has important guiding significance for clinical treatment of etiology.
