Cost-Effectiveness Analysis of Early Operation vs Percutaneous Drain Placement with Interval Operation for Complicated Diverticulitis with Abscess Formation

Early operation was the dominant strategy for the surgical management of complicated diverticulitis and should be considered more frequently.

This threshold for strategy variation emphasizes the importance of shared decision-making with patients in cases of acute complicated diverticulitis.
