Umbilical pilonidal sinus with the urachal tract: A case managed with umbilicus-preserving laparoscopic urachal cyst and tract excision

Abstract

Abstract The umbilical pilonidal sinus (UPS) is a rare clinical entity and is not easily diagnosed unless there is a high suspicion. Pilonidal sinuses are most frequently seen around the gluteal cleft, but occasionally can be observed on other areas of the body, including the breast, webs of fingers, axilla and umbilicus. UPS is one of the rarest subtypes. Risk factors for UPS are similar to those for gluteal cleft pilonidal cysts and include young age, male gender, obesity, hairy body and poor personal hygiene. The traditional approach of treatment is usually conservative or surgical excision of the sinus with or without umbilectomy through the open technique. We discuss a case of UPS in an adult male having a concurrent urachal cyst with the urachal tract. We report our experience in laparoscopic management of this case after the failure of a conservative approach, with favourable outcomes at 1-year follow-up.
