Introduction

Candidate patients for colorectal cancer surgery may present malnutrition due to the tumor pathology itself. This must be corrected preoperatively in order to achieve good surgical results.

Methods and objectives

Objectives

Determine the nutritional status in our population and to know the type of nutritional support necessary.

Methods

Descriptive study including preoperative patients for scheduled surgery for colorectal carcinoma and excluding those who require neoadjuvant treatment or urgent surgery, during a period of 12 months (May 2019 to April 2020). In the month prior to the intervention, they are evaluated in a nutrition consultation, indicating the nutritional support, according to their condition.

Results

123 patients, aged 68.8 ± 10.19 years old, were studied, 59.3% were men. The Global Subjective Assessment was 51.2% type A (well nourished), 39% type B (moderate malnutrition or risk of malnutrition) and 8.9% type C (severe malnutrition). The anthropometric variables analyzed were weight in men (presented at the time of consultation) of 82.40 kg ± 17.14 and BMI of 28.92 ± 5.31 kg/m², in women weight of 69.52 ± 14.71 and BMI of 28.90 ± 5.32 kg/m². Abdominal circumference of 105.8 ± 12.1 cm. Regarding the analytical values, they presented Albumin of 3.66 ± 6.13 g/dl and Transferrin of 270.4 ± 61.7 mg/dl. The results indicated a high prevalence of abdominal obesity and mild protein malnutrition. 4.4% of the patients received complete home enteral nutrition, generally due to intestinal subclusive symptoms (from the consultation assessment until the day of the intervention). In 91.1%, oral nutritional supplements were indicated as presurgical preparation during the 5 days prior to surgery.

Conclusion

The PCCR colorectal cancer patients, preoperatively after scheduled surgery, presented a low prevalence of severe malnutrition, which required total enteral nutrition until the intervention. The prevalence of abdominal obesity was high. Studies are needed to assess the surgical impact of the improvement in nutritional status in these patients.
