Objectives: we are aiming to investigate and compare the outcome of early elective surgery for sigmoid diverticulitis directly after improving the acute attacks versus delayed elective interventions. Methods: Our study included 47 patients of sigmoid diverticulosis. Patients were divided into 2 groups; group A (25 patients) who underwent surgery in the same hospital admission of the acute attack after controlling the manifestation of the acute inflammation within one week of admission, and group B (22 patients) who underwent surgery 4-6 weeks after subsidence of the acute attacks during the inflammation-free interval. We had collected and recorded patients’ data during and after a surgical procedure, then data were statistically analyzed. Results: No significant differences between group A and B regarding the mean operative time (p-value 0.067). However, the mean amount of the intra-operative bleeding and the rate of Hartman’s procedure were significantly higher in the early elective group (p-value 0.034 versus 0.021). About the conversion rate and the men postoperative ICU as well as hospital stay days, there were no significant variances between the two groups. Conclusion: Medically and financially, the early elective operations for patients following the clinical recovery of the AD attacks are preferred than the delayed elective surgeries.
