Which factor is a risk factor related to surgical technique for fistula formation?

Explanation:
Fistula formation related to surgical technique most directly stems from problems at the join where two ends are connected—the anastomosis. If there are technical difficulties during this step, the suturing may be insecure, there may be undue tension on the connection, or blood supply to the tissue can be compromised. All of these issues undermine healing and can lead to leakage at the anastomosis, which can evolve into a fistula. In contrast, short operative time is not itself a risk factor tied to technique; and good tissue quality and adequate nutrition improve healing, reducing risk rather than increasing it.
