I work in an intestinal failure unit and perform approximately 40 ECF repairs per annum. I find it hard to believe that these plugs would work in any of our patients. NICE have recently published guidelines. The surgery is complex but with good success rates. Also what about the abdominal wall? We normally have to reconstruct this with Ramirez type techniques and biological mesh etc. A plug would obviously leave this unattended. Which type of fistulas would be suitable? The evidence seems extremely poor to say the least.
