Umbilical Pilonidal Sinus Disease: Predisposing Factors and Treatment

Abstract

Pilonidal sinus disease is a common problem of sacrococcygeal region. However, it is also observed in the periumbilical area. There are only a few reports about umbilical pilonidal sinus in the literature. In this study, 26 patients (24 men (92 %), 2 women (8 %) with a mean age of 22 years) with umbilical pilonidal sinus disease were included. Predisposing factors, patient characteristics, treatment modalities, and their results have been studied. Male sex, young age, hairiness, deep navel, and poor personal hygiene were found to be predisposing factors. Twenty-five patients were treated conservatively. However, two patients failed to respond to conservative treatment. Those patients underwent surgery where umbilectomy was carried out without reconstruction. One patient was also operated on for the preoperative misdiagnosis of irreducible umbilical hernia. Patients were followed for 14-96 months. We recommend conservative treatment in patients with umbilical pilonidal sinus. Surgery should be performed in recurrent cases resistant to conservative treatment. The importance of differential diagnosis of umbilical pilonidal sinus from other umbilical pathologies is also emphasized.

Excision without Primary Closure Treatment of Pilonidal Sinus and its Gender Incidence

“…Incidence of pilonidal sinus is 26 cases per 100,000 people and affecting young adult men more than women. [8][9][10] The pathogenesis of pilonidal disease is not known but There are two theories they are acquired and congenital theories. Majority of author support the acquired theory.…”

Umbilical Pilonidal Sinus: A Case Report

“…Umbilical pilonidal sinus is a quite uncommon disease. Even though there is no particular agreement about the treatment of this disease, various and different treatment methods (from conservative modalities to umbilectomy) exist in literature [1,[3][4][5][6][7][8]. We present a patient with umbilical pilonidal sinus who was successfully treated by sinus excision with conserving umbilicus.…”

“…Pilonidal sinus is a disease which is characterized by a granulomatous reaction to a hair shaft penetrating epidermis from the cutaneous surface [1]. Although commonly seen in sacrococygeal region, it is also observed in the periumbilical area [2].…”

Preauricular pilonidal sinus: The first reported case

“…Pilonidal sinus occurs mainly in the sacrococcygeal area [4]. However, it may also occasionally occur in other areas like axilla, groin, interdigital web, umbilicus, nose, suprapubic area, clitoris, prepuce, penis, or occiput [5].…”
