Purpose/Background: Diverticulitis management has shifted towards conservative approaches, yet some cases still require surgery. This study aims to identify risk factors for surgical intervention in diverticulitis patients, facilitating early recognition and appropriate treatment planning.

Methods/Interventions: This retrospective study analyzed medical records of all consecutive patients diagnosed and treated for diverticulitis at a single institution from April 2019 to May 2024. Data collection included baseline clinical characteristics, computed tomographic findings at diagnosis, and detailed treatment information. The primary endpoint was treatment type, categorized as either surgical or non-surgical management. Statistical analysis was performed to identify factors associated with the need for surgical intervention.

Results/Outcomes: The study included 616 patients with a median age of 47 years. The cohort comprised 314 males (51.0%) and 302 females (49.0%). Patients were divided into two groups: 31 (5.0%) in the surgical group (colonic resection) and 585 (95.0%) in the non-surgical group. The median age was significantly higher in the surgical group (70 vs 46, p < 0.001). The surgical group had a significantly higher proportion of patients with one or more previous diverticulitis events (35.5% vs 4.1%, p < 0.001). In the right-sided cases (n=481), there were only 7 patients (1.5%) in the surgical group , whereas in the left side (n=111), there were 23 patients (20.7%) in the surgical group. (p < 0.001). After completing treatment for diverticulitis, 13 patients (41.9%) in the surgical group and 209 patients (35.7%) in the non-surgical group underwent follow-up colonoscopy (p = 0.610). Among the 222 of 616 patients who underwent colonoscopy, a total of 3 (1.4%) were diagnosed with colonic adenocarcinoma and 41 (18.6%) showed no evidence of diverticula. Multivariable regression analysis identified several factors significantly associated with surgical intervention: albumin < 3.0 mg/dL, one or more previous events of diverticulitis, left-sided diverticulitis, and perforation on initial computed tomographic imaging.

Conclusion/Discussion: Several risk factors for surgical intervention in diverticulitis were identified. Early recognition of these factors including low albumin, previous history of diverticulitis, left-sided and complicated diseases can help optimize and consider treatment strategies for surgery. Additionally, due to the 1% incidence of colorectal cancer in diverticulitis patients, follow-up colonoscopy should be considered for high-risk patients with malignancy.
