Abbasi, H.R., Yazdani, S., Mehrabani, D., Tanideh, N., Vasei, M., Rasehkhi, A.R., Hosseini, S.V. and Amini, M. 2008. Evaluation of mushroom catheter for diverting loop ileostomy: an experimental study in dog. J. Appl. Anim. Res., 33: 25–28.

This experiment was conducted to examine a new surgical method of ileostomy for fecal diversion using mushroom catheter in an animal model. In 10 dogs, a mushroom catheter was inserted in the lumen of terminal ileum and was fixed to the abdominal wall. It was removed after 2 weeks and an enterocutaneous fistula was created. Finally at the end of 4^th week after operation, samples were provided from terminal ileum and the colon anastomosis site and were studied radiologically and pathologically. Two dogs succumbed to complications and the remaining 8 dogs were alive till the end of 4^th week post-operation. In all dogs, catheters were removed by themselves in 8–13^th post-operation day and drainage from the created enterocutaneous fistula (site of mushroom catheter) was stopped after 2 weeks. Radiological studies showed closure of fistula without any stenosis in the site of purse suturing of the lumen of terminal ileum at the end of 4^th week post-operation. We suggest this new method of ileostomy to be able to divert fecal stream for about one month (in order to preserve distal colon anastomosis).
