Process of the implantation and fixation of the “fistula stent”. A: Four double pipes were used to drainage enteric fistula effluent before implantation ; B: The process of implantation; C: After the implantation the stent can still be seen (red arrow); D: The process of fixation by suturing the small protuberance with a latex tube overhanging the abdominal wall; E: After the accomplishment of implantation, only one double pipe was needed for drainage; F: Contrast-mediated fistula angiography was conducted to verify the effectiveness of the stent and the contrast agent flowed past the stent without obstruction.
