Intracolonic Migration of an Abdominal Drain through an Appendiceal Fistula: A Rare Post-Appendectomy Complication Managed Conservatively

In patients with appendiceal fistula undergoing conservative management, the main complication is inadequate or incomplete drainage of the fistula, which often leads to the consideration of more aggressive measures. We describe an extremely rare complication with an abdominal drain: intracolonic migration through appendiceal fistula. No such cases have been described in the literature. Our aim is to describe our experience and the therapeutic approach adopted to offer a less invasive treatment alternative, avoiding major surgeries, with good results.
