Early diagnosis of anastomotic leakage after anterior resection for rectal carcinoma / 中华普通外科杂志

ABSTRACT

Objective:To search for valuable laboratory indexes of early diagnosis of anastomotic leakage after anterior resection for rectal carcinoma.Methods:From Sep 2017 to Jan 2019, 128 patients with colorectal cancer underwent anterior rectal resection at the Department of Colorectal & Anal Surgery, the 940 Hospital of the Joint Logistics Support Force.Results:Anastomotic leakage occurred in 16 of 128 patients (12.5%). Definite diagnosis of anastomotic leakage was made on between 2nd and 9th day, postopera tively averagign (6.13±2.00) days. Tumor location was a risk factor for anastomotic leakage with the incidence significantly lower when the distance from the lower edge of the tumor to the anal margin >7 cm than when the distance ≤7 cm ( χ 2=6.022, P=0.014). The percentage of increase in peripheral blood leukocytes, neutrophils, serum interleukin-6, C-reactive protein and procalcitonin in patients 3-5 days after surgery significantly related to the occurrence of anastomotic leakage (all P<0.05). The area under the working characteristic curve of the subjects with the percentage of C-reactive protein, procalcitonin, interleukin-6, leukocytes and neutrophils from the 3rd to the 5th day after operation was greater than 0.5. Conclusion:C-reactive protein, procalcitonin, interleukin-6, leukocyte and neutrophil percentage are risk factors predicting anastomotic leakage after anterior resection of rectal cancer.
