Non-operative management of umbilical pilonidal sinus: One more step towards ideal therapy

There are controversies regarding the management of umbilical pilonidal sinuses. The current study aims to report on the efficacy of a non-operative, umbilical conserving procedure in the treatment of umbilical pilonidal sinus. This is a prospective, single cohort study. The cases were managed in a single private practice center. Patients were assessed and managed throughout the previous nine years (from January 2013 to June 2022). The required information was obtained from the center's medical database. The current study included 114 patients. There were 82 (71.9%) male patients. The patients' ages varied from 14 to 56 years (mean = 23.24). The umbilicus was retracted under local anesthesia. The sinuses were cleaned with povidone-iodine. Following the drying of the cavity, the mixture was put in the umbilicus, and the area was dressed. The amount of mixture was determined by the size of the cavity. Following treatment, the patients were directly discharged home with instructions to remove all hair from the chest and abdomen and keep the dressing dry for three days. After three days, the patients were advised to use a clean cotton swab to remove the injected mixture. Recurrence was reported in 5 cases (4.4%). The current technique might be used effectively in the treatment of umbilical pilonidal sinus. It is an umbilical preserving technique with a minimal recurrence rate.
