Early colectomy is more cost-effective than interval colectomy for managing complicated diverticulitis with abscesses, leading to better outcomes for patients.

• Early colectomy costs $8,852 less per patient and yields an incremental increase of 0.57 quality-adjusted life years (QALYs).
• This approach was deemed cost-effective in 96% of scenarios analyzed.

Surgeons should consider early colectomy more often, but weigh patient preferences and quality of life when advising on management options.

• Interval colectomy remains viable if drainage does not significantly impact a patient’s well-being.
