The aim of the work: to improve treatment outcomes in patients with rectal cancer by analyzing key risk factors for anastomotic leakage (AL) at the preoperative, intraoperative, and postoperative stages.
Materials and Methods. This retrospective single-center study included 92 patients with stage I–III rectal adenocarcinoma (TNM: cT1–4, N0–2, M0), located within 15 cm from the anal verge and without involvement of the anal sphincter. All patients underwent laparoscopic anterior or low anterior resection with colorectal anastomosis. Based on the presence of clinically significant leakage, patients were divided into two groups: AL (+) – 17 patients (18.5 %) and AL (-) – 75 patients (81.5 %). A range of clinical, morphological, and surgical variables were analyzed and categorized according to treatment stages.
Results. The rate of clinically significant AL was 18.5 %. Statistically significant risk factors included: distal tumor location (5–10 cm from the anal verge) (p=0.001), prolonged operative time (p=0.024), D3 lymph node dissection (p=0.009), use of ≥2 linear stapler firings (p=0.020), absence of splenic flexure mobilization (p=0.012), and ligation of the left colic artery (p=0.001). Elevated C-reactive protein level on postoperative day 3, fever, and tachycardia may serve as early clinical-laboratory markers of AL and indicate the need for prompt diagnostic and therapeutic interventions.
Conclusions. Identifying key risk factors for colorectal anastomotic leakage – particularly those related to tumor location, surgical technique, and early signs of inflammation – enables timely detection of high-risk patients and prevention of postoperative complications.
