Background: Treatment for diverticular disease has evolved over time. In the United States, there has been a trend towards minimally invasive surgical approaches and fewer postoperative complications, but no study has investigated this subject in the Veterans Health Administration.
Methods: This retrospective review identified patients undergoing elective surgery for diverticular disease from 2004 to 2018. Demographics, comorbidities, operative approach, rates of ostomy creation, and 30-day outcomes were compared. The 15-year time period was divided into 3-year increments to assess changes over time.
Results: 4198 patients were identified. Complication rate decreased significantly over time (28.1%-15.7%, p < 0.001), as did infectious complications (21.5-6.3%, p < 0.001). Median hospital length-of-stay decreased from 7 to 5 days (p < 0.001). Rates of laparoscopic surgery increased over time (17.7%-48.1%, p < 0.001).
Conclusions: Increased utilization of laparoscopy in veterans undergoing elective surgery for diverticular disease coincided with fewer complications and a shorter length-of-stay. These trends mirror outcomes reported in non-veterans.
