Abstract

Introduction: The prevalence of obesity has a substantial impact on colorectal surgeons, as it is associated with
an increased incidence of conditions that commonly require colorectal resection, such as cancer, diverticulitis, and
inflammatory bowel disease. This study aims to evaluate the impact of body mass index (BMI) on the surgical
outcome of colorectal cancer (CRC).
Patients and methods: This retrospective study included 100 patients aged ≥ 18 years, both sexes undergoing
colorectal carcinoma surgery. Patients were divided into two groups: Group I: Obese patients (BMI ≥ 29 kg/m2)
and Group II: Non-obese patients (BMI<29kg/M2). The preoperative, intraoperative, and postoperative data were
retrieved from the hospital database.
Results: The interval between the operation and ileostomy closure was significantly higher in group I than in
group II (P<0.05). Total postoperative complications were significantly higher in group I than in group II [21
(39.62%) vs 3 (11.11%), P=0.009]. Hospital stay was significantly higher in group I than in group II (8.19 ± 3.2
vs 6.11 ± 2.52; P=0.004).
Conclusions: BMI significantly impacts surgical outcomes in patients with CRC. Awareness of the BMI’s influence
on surgical complications, and the development of personalized clinical strategies are important to optimize
treatment and improve patient outcomes.
