Colorectal anastomosis in rectal cancer surgery: methods of anastomotic leakage prevention

Abstract

One of the most serious complications after low anterior resection is the failure of sutures of colorectal anastomosis, which is the most common surgical complication that results in patient’s death. Promptly diagnosed anastomotic leakage in postoperative period is challenging. Nevertheless, elimination of risk factors in preoperative period can significantly reduce complication rates.The purpose of this review article is to analyze possible risk factors and methods for preventing colorectal anastomosis leakage.An important area of prevention and optimization of treatment options for anastomotic leakage is the development of prognostic measures to eliminate risk factors. We see the prospects for this direction in the introduction of a nomogram, which allows the surgeon to assess the possible outcomes of the operation, to choose the optimal tactics with a minimum risk of complications, as well as the introduction of methods to avoid or prevent the development of complications of colorectal anastomosis.
