Pili Multigemini Is a Possible Risk Factor for Pilonidal Sinus Disease

Abstract

The aim of this study is to analyze both previously proposed and new risk factors for the development of pilonidal sinus. This is a prospective case-control study consisting of 145 patients with pilonidal sinus disease (n = 45) and a control group (n = 100). All patients were admitted to the department of general surgery between January 2013 and May 2015. The patients' age, family history, medical history, sitting time in a day, sitting posture, body mass index (BMI), Garn hairiness score, and hair type were evaluated. There were significant differences between the groups in the following characteristics: age (P = 0.01); positive family history (P = 0.01); medical history (P = 0.01); sitting time in a day (P = 0.01); sitting posture (P = 0.01); BMI (P = 0.01); Garn score (P = 0.01); and hair type. Multivariate logistic regression analysis indicated that positive family history (P = 0.03); Garn score (P = 0.05); medical history (P = 0.01); and sitting posture (P = 0.02) were independent risk factors for the development of pilonidal sinus disease.
