Introduction
Patients undergoing coronary artery bypass graft surgery constitute a large population of patients with anatomically similar incisions created under similar circumstances. Our study aimed at analysing and comparing rates of surgical site infections (SSIs) at the sternotomy sites based on the material used for skin closure of the sternal wound with special emphasis on presence of risk factors such as diabetes (glycated haemoglobin (HbA1c) > 9) and obesity (body mass index (BMI) > 30 kg/m2) in the 2 respective groups.

Material and methods
This is a retrospective observational study. A total of 864 patients were included in the study. The patients were grouped into 2 groups depending on the sternal wound closure strategy used. One group consisted of patients in whom polyamide sutures were used for skin closure, while the other group comprised patients in whom skin staples were used for skin closure. Incidence of sternal wound SSIs in both groups was noted. Co-morbid conditions such as diabetes mellitus (with HbA1c > 9) and obesity (BMI > 30 kg/m2) were noted and analysed as contributory factors for SSIs.

Results
Group A comprised 432 patients out of whom 42 (9.72%) had sternal wound SSIs. Group B comprised the other 432 patients of whom only 20 (4.62%) developed sternal wound SSIs. Co-morbid conditions were analysed in each group. Group A showed SSI in 22/64 (34.3%) diabetic patients, 6/28 (21.8%) obese patients and 16/22 (72.72%) with diabetes and obesity. Group B showed SSIs in 6/56 (10.715) diabetics, 4/26 (6.01%) obese and 4/24 (16.67%) with diabetes and obesity.

Conclusions
By pairing staples and sutures, we observed a significantly lower incidence of total wound complications with suture than with staple closure.
