Umbilical pilonidal sinus (UPS) is a rare condition mostly seen in hairy young males and characterized by pain, swelling, bleeding, and seropurulant discharge from the umbilicus. Although it has long been recognized, it is yet little known clinical entity. Furthermore, there are some doubts regarding its best treatment options. Umbilicus is one of the ideal sites for pilonidal sinus formation. It occurs penetration of vulnerable skin of the umbilicus by hair which causing a foreign-body reaction and development of the sinus. Treatment depends on the severity of the disease, ranging from good personal hygiene to surgical excision of umbilical complex. However, most of the cases are administered with chronic intermittent form of the disease; for those patients the best permanent solution is umbilicus-preserving surgery.

Case series Patient: Male, 26 • Female, 21 Final Diagnosis: Umbilical pilonidal sinus Symptoms: Hair tuft in the umbilicus • pain • periumbilical dermatitis • purulent discharge from the umbilicus • skin lesions • pruritis Medication: — Clinical Procedure: Umbilicus preserving surgery Specialty: General Surgery • Dermatology • Plastic Surgery Objective: Rare disease Background: Umbilical pilonidal sinus (UPS) is a rare disease of young, hirsute, dark men with deep navels and poor personal hygiene. UPS could easily be misdiagnosed and mistreated due to its rarity and lack of awareness of the condition by physicians. However, the diagnosis is easy to establish with physical examination and a detailed history. Although it is being diagnosed and reported more frequently, there is still no consensus regarding best treatment options. Case Report: In this report, we present two cases of UPS, one in a man and one in a woman, who had typical symptoms of pain, swelling, and intermittent malodorous discharge from the umbilicus. They had small sinus openings with hair protruding deep in the navel. Because these two patients had previous histories of failed conservative treatments, an umbilicus preserving surgery was performed for both cases. Wounds were healed in 2–3 weeks with acceptable cosmetic results. During a more than 2 year follow-up period, there were no signs of recurrence. Conclusions: In a patient presenting with a history of intermittent discharge, itching, pain, or bleeding from the umbilicus and the presence of granulation tissue with or without protruding hair and periumbilical dermatitis, the diagnosis should consider UPS, even in female patients. Treatment generally depends on the severity of the disease, ranging from good personal hygiene to surgical excision of umbilical complex. The treatment of choice for chronic intermittent cases is surgical removal of the affected portion; paying special attention to cosmetic appearance.

Ozcan, Onder/0000-0001-8252-3339 WOS:000415221700007 PubMed: 28359560 Background: The Limberg flap (LF) procedure is widely performed for the treatment of sacrococcygeal pilonidal sinus (SPS); however, recurrences continues to be observed. The aim of this study was to assess the relationship between LF designs and the risk of SPS recurrence. Methods: Sixty-one cases with recurrent disease (study group) and 194 controls, with a minimum of 5 recurrence-free years following surgery (control group), were included in the study. LF reconstructions performed in each group were classified as off-midline closure (OMC) and non-OMC types. Subsequently, the 2 groups were analyzed. Results: After adjustment for all variables, non-OMC types showed the most prominent correlation with recurrence, followed by interrupted suturing type, family history of SPS, smoking, prolonged healing time, and younger age. The best cut-off value for the critical distance from the midline was found to be 11 mm (with 72% sensitivity and 95% specificity for recurrence). Conclusions: We recommend OMC modifications, with the flap tailored to create a safe margin of at least 2 cm between the flap borders and the midline. (C) 2017 Elsevier Inc. All rights reserved.

Background Umbilical pilonidal sinus (UPS) is one of the most neglected disorders, and there is still no clear consensus regarding optimal treatment of the disease. We therefore present our data from a prospective, randomized, controlled clinical trial comparing conservative vs surgical treatment of UPS. Study Design The study was conducted in Turkey between January 2012 and November 2015. All eligible patients with the diagnosis of UPS (n = 84) were randomized for either conservative treatment (CT, n = 42) or surgical treatment (ST, n = 42). All patients were followed up for at least 2 years; then, the results of both groups were compared. The primary outcomes were initial healing, recurrence, and the cure rate of the disease after each treatment modality. Results Mean (± SD) age of the patients was 20.83 ± 5.73 years old, and the majority were men (94%). Nearly 60% of the patients had a deep navel, and 55% had intense hair status. The main symptoms were drainage and wetness, pain, itching, and malodor. Overall, in 10 (27.8%) patients, relapse of the disease was observed in the CT group; it was observed in only 1 patient in the ST group (p = 0.002). Initial healing time was significantly shorter in the ST group (p = 0.001). Of the 81 patients who completed the 2-year follow-up, a cure could be obtained in only 28 of 41 patients in the CT group; it was achieved in all 40 patients in the ST group (68.3% vs 100%, respectively; p = 0.0001). Conclusions This study provided evidence that surgical treatment is superior to conservative surgery regarding the primary and secondary outcomes of UPS at least 2 years after surgery.
