Abstract

Background: Anastomotic leakage (AL) is a common complication after anterior resection of rectal cancer. Few studies have been conducted to determine whether the traditional predictors of AL can be applied to elderly patients (age ≥ 80) undergoing anterior resection (AR) or low anterior resection (LAR) of rectal cancer. This study was designed to explore the predictive factors for AL after anterior resection of rectal cancer in patients over 80 years old.

Methods: From January 2007 to May 2019, consecutive elderly (age ≥ 80) rectal cancer patients undergoing AR or LAR at our institution were systematically reviewed. The general information, perioperative outcomes, and comorbidities were collected.

Results: A total of 288 consecutive patients were included in this study. The average age was 82.8 ± 2.4 years, and 30 (10.4%) patients developed AL. The univariate analyses showed that neoadjuvant therapy (50.0% vs. 27.9%, P = 0.013), the number of stapler firings ≥ 3 (60.0% vs. 36.0%, P = 0.011), and coronary heart disease (CHD) (46.7% vs. 17.8%, P < 0.001) were associated with an increased incidence of AL. The multivariate analysis showed that the number of stapler firings ≥ 3 (OR = 4.77, 95% CI = 1.33-15.21, P = 0.035) and CHD (OR = 8.33, 95% CI = 1.94-13.05, P = 0.003) were independent risk factors for AL.

Conclusion: The number of stapler firings ≥ 3 and CHD were independent risk factors for AL in elderly patients (age ≥ 80) with rectal cancer. A temporary ileostomy or the Hartmann procedure is recommended for patients with CHD, male patients, patients considered to be obese, and patients with a lower tumor location, which may increase the number of stapler firings. Certainly, we recommend that the number of stapler firings should be minimized to alleviate the economic and physical burden of patients.
