Objective The clinical application value of contrast-enhanced CT analysis in gastrointestinal bleeding diseases.Methods A total of 160 patients with gastrointestinal bleeding who were selected to visit Songxian People's Hospital from April 2022 to April 2024 were all given enhanced CT scans,and the bleeding site and imaging characteristics were recorded.Compare the CT values of bleeding points in arterial,venous,and delayed phases of contrast-enhanced CT.Results A total of 160 patients were confirmed to have bleeding sites through enhanced CT examination,with 72 cases in the esophagus,accounting for 45.0％;46 cases of stomach,accounting for 28.7％;42 cases in the intestine,accounting for 26.3％.Eight cases showed intestinal vascular malformation,accounting for 5.0％,specifically manifested as local blood vessels thickening,increasing,uneven thickness,and disorder,including 2 cases of gastric vascular malformation,2 cases of duodenal vascular malformation,2 cases of small intestinal vascular malformation,and 2 cases of rectal vascular malformation.Seven-two cases of esophageal varices were diagnosed as cirrhosis,accounting for 45.0％.Fifty-four cases presented as intestinal tumors,accounting for 33.8％.The specific manifestations were soft tissue density masses or irregular thickening of the intestinal wall,accompanied by peripheral lymph node enlargement and intestinal lumen stenosis.Among them,36 cases were gastrointestinal stromal tumors;4 cases of colon cancer;4 cases of duodenal cancer;8 cases of gastric cancer;2 cases of small intestinal lymphoma.Twenty-six cases showed local or segmental intestinal mucosal abnormal enhancement,accounting for 16.5％,of which 4 cases had local mucosal abnormal enhancement in the jejunum;4 cases of abnormal enhancement of local mucosa in the ileum;18 cases of abnormal enhancement of the mucosa in the ileocecal region.The CT values of bleeding points in the venous and delayed phases were higher than those in the arterial phase(P＜0.05).There was no significant difference in CT values between bleeding points in the venous phase and those in the delayed phase(P＞0.05).Conclusion Enhanced CT can clarify the location and cause of gastrointestinal bleeding,assist in accurately evaluating the patient's condition clinically.In addition,venous phase and delayed phase are the best time to display the bleeding point,and clinical practice can choose a reasonable scanning time based on the patient's actual situation.
