Objective To observe the effect of X-ray-guided placement of intestinal obstruction tube for treating malignant bowel obstruction(MBO)caused by gynecological malignant tumors.Methods Data of 60 patients with intestinal MBO after surgical operations of malignant gynecological tumors,including 30 cases underwent X-ray-guided intestinal obstruction tube placement(group A)and 30 cases underwent traditional nasogastric tube placement(group B),all followed by continuous gastrointestinal decompression were retrospectively analyzed.The remission of MBO symptoms,time of exhaust and defecation,so as diet recovery after treatment were compared between groups.The mean drainage volume within 24 h,tube retention time and treatment-related complications were recorded,and the survival of patients within 1 year after treatment were followed up.Results All 60 patients were successfully catheterized.The time of exhaust and defecation,oral feeding and tube retention time after catheterization in group A were shorter than those in group B(all P＜0.05),while the mean drainage volume within 24 h in group A was larger than that in group B(P＜0.05).No significant difference of relief rate of intestinal obstruction symptoms was found between groups(P=0.472).Minor nasal bleeding occurred in 8 cases,and oropharyngeal discomfort occurred in 4 cases in group A,while each in 5 cases in group B,all relieved without special treatments.No significant difference of treatment-related complication was observed between groups(P=0.361).One year after treatments,28 cases were followed up and 2 cases were lost in both groups,and no significant difference of survival rate was detected between group A(7/28,25.00%)and group B(5/28,17.86%)(P=0.745).Conclusion X-ray-guided placement of intestinal obstruction tube was safe and effective for treating MBO caused by malignant gynecological tumor.

Chylothorax is one of the complications of surgery and lymphatic diseases. The incidence rate of chylothorax has been increasing in recent years. X-ray-guided interventional therapy is a new method for treating chylothorax, and its curative effect is no less than the traditional surgical treatment. Based on discussing the aetiology and diagnosis of chylothorax, this paper briefly summarizes the application progress of X-ray-guided interventional therapy for chylothorax to provide further reference and a basis for clinical practice.
