Purpose/Background: Anastomotic leakage is a severe complication in colorectal surgery. New strategies have been explored to reduce its incidence, and the usefulness of intraoperative colonoscopy in preventing it has been debated. This technique has been shown to detect anastomotic defects before they result in clinical consequences for the patient.

Objectives: To evaluate the clinical impact of intraoperative colonoscopy in assessing anastomoses in patients undergoing colectomies with rectal anastomoses.

Methods/Interventions: A retrospective study was conducted at ABC Medical Center with patients who underwent colectomy between January 1, 2020, and April 30, 2024. The use of intraoperative colonoscopy was compared to other methods for evaluating rectal anastomoses. Data were analyzed using logistic regression with Chi-square for categorical variables and t-test for continuous variables.

Results/Outcomes: A total of 128 patients were included: 45 with intraoperative colonoscopy and 83 with other methods. A statistically significant difference was observed in the incidence of postoperative leakage: 18 patients without intraoperative colonoscopy experienced leakage compared to 1 patient in the intraoperative colonoscopy group (p: 0.003, OR 0.79, 95% CI 0.010-0.613). Additionally, clinical outcomes were reflected in the length of hospital stay, which was shorter in patients without postoperative leakage: 22 ± 8.5 vs. 8.5 ± 3.2 days (p: 0.001).

Conclusion/Discussion: Intraoperative colonoscopy is a safe method for evaluating colorectal anastomoses and may reduce the incidence of postoperative leakage.
