Long-term seton drainage for high and fistula in Crohn's disease is efficacious in both treating sepsis and preserving anal sphincter function.

In our experience, sleeve resection for stage I provides comparable survival to that of standard resection at equal stage. However, in patients with pathologically N1 disease, who can tolerate a pneumonectomy, a randomized study is mandatory to confirm that sleeve lobectomy can be performed without the risk of decreasing long-term survival. In our study, patients who required an associated vascular resection demonstrated a poor survival.
