A clinical efficacy study of interventional catheter drainage combined with ozone therapy for the management of postoperative enterocutaneous fistula / 实用医学杂志

ABSTRACT

Objective To evaluate the efficacy of interventional catheter drainage combined with ozone therapy for the management of postoperative enterocutaneous fistula. Method A total of 70 patients with postoperative enterocutaneous fistula were enrolled and divided into group A (35, conventional surgical treatment) and group B (35, interventional catheter drainage and ozone therapy). Clinical efficiency, hospital stays, hospital expenses and complications were compared. Follow-up observations of the infection score in 2 groups before and after treatment (3 days, 1 week, 2 weeks and 1 month) were also compared. Results 30 cases in group A recovered (85.7%), and 28 cases in group B recovered (80.0%), the result of which shows no statistic significance. The hospital stays and expense in group B were significantly lower than those in group A. 4 cases of group A suffered from incision complications , 2 intra-abdominal hemorrhage , 1 severe pneumonia and 1 septic shock. 2 cases in group B suffered from stomachache. The differences can be shown significantly. The infection score between the two groups shows no significant difference, but the score was found to be obviously lower after treatment than before. The infection score decreased by an average of 19.9 in group A and 23.5 in group B,indicating a better anti-infective effect in group B. Conclusion Interventional catheter drainage combined with ozone therapy for the management of postoperative enterocutaneous fistula is safe and effective, with lower hospital stays and expense.
