Abstract

Purpose: We investigated which obesity-associated parameters can better predict the risk of anastomotic leakage (AL) in rectal cancer patients that underwent anterior resection of the rectum.

Method: Patients (n = 589) who underwent anterior resection of the rectum with a primary anastomosis were included in this study, including 44 patients with AL and 545 without AL. Univariate analysis was used to compare demographic characteristics and to select risk factors that were used in one-to-one propensity score matching (PSM). Obesity-associated parameters, including preoperative body mass index (BMI), visceral fat area (VFA), subcutaneous fat area (SFA), total fat area (TFA), VFA/TFA ratio, serum cholesterol, and triglycerides, were compared between the two groups after PSM.

Results: Sex, neoadjuvant chemotherapy, operation time, and anastomosis level from the anal verge were risk factors for AL (p < .05). After the PSM, BMI, VFA, SFA, TFA, VFA/TFA, and serum cholesterol showed no significant difference between the two group (p > .05). However, the level of serum triglycerides was an independent risk factor for AL (p = .024, odds ratio = 2.95).

Conclusions: Serum triglycerides have potential as a predictive indicator for AL, which may improve the treatment and outcomes of patients with AL.
