Conservative Versus Surgical Treatment of Umbilical Pilonidal Disease

Not Applicable

Completed

Brief Summary: The aim of the study was to compare the results of conservative and surgical treatment, to create an algorithm for the management of the disease, and gain more information about the etiology, pathogenesis, and course of the disease. The investigators hypothesise that surgical treatment of UPS will be better than conservative management in terms of recurrence rate, healing time, patient comfort and satisfaction, and cost effectiveness.

Detailed Description: Because of its rarity, umbilical pilonidal sinus (UPS) is still poorly understood in terms of diagnosis, etiology, and the best treatment options.

UPS is thought caused by hair penetrating the skin, leading to a foreign-body reaction and development of a sinus lined with granulation tissue. Most of the patients complain of pain, discharge or bleeding from the umbilicus when symptoms develop. It can be diagnosed with a careful examination, in which hairs can be seen deep in the umbilicus and usually protrude from a small sinus.

Regarding the optimal treatment of the disease, a complete consensus has not yet been achieved. Some publications are recommended conservative treatment, while surgical treatment is recommended in others.

A more meaningful comparison of the two modalities is that of a randomized controlled trial. We, therefore, present our data of prospective randomized controlled clinical trial comparing conservative versus surgical treatment of UPS.

This was a multicenter, prospective balanced randomization, double blind, active-controlled, parallel-group, superiority study conducted in Turkey, under the direction of a principal investigator (MK). Eligible patients with UPS were randomized for either conservative treatment (CT) or surgical treatment (ST), and then the results of both groups were compared.

Recruitment & Eligibility

Inclusion Criteria

all patients willing to participate to the study with the diagnosis of umbilical pilonidal sinus

Exclusion Criteria

no informed consent
serious coagulation abnormalities
known allergy to local anesthetics
pregnancy, or women who refused contraception at the time of treatment
other concomitant umbilical pathologies such as umbilical hernia, granuloma, dermoid cyst
the patients who diagnosed with urachal and omphalomesenteric anomalies through radiological investigation
patients who underwent umbilical operation

Primary Outcome Measures

Name	Time	Method
Cure Rate	2 year after initial treatment	Primary outcome was the cure rate. Absence of recurrence within two year after the first treatment was considered as a cure. Recurrence was defined as the appearance of a new, active discharging sinus or granulation tissue with/without a bit of hairs in the deep of the umbilicus within two years after therapy.

Secondary Outcome Measures

Name	Time	Method
Healing Time	two year	the time form initial treatment to healing the wound and/or sinus and/or granulation tissue and no any sign of drainage with no longer need for dressing and wound care in either treatment arms.
Visual Analogue Scale for Patient Satisfaction (VAS-PS)	30 days	Well-being and satisfaction scales comprised linear metric scales known as "visual analogue scales," with grades from 0 (worst imaginable health state and extremely dissatisfied with the treatment) to 100 (best imaginable health state and extremely satisfied with the treatment).
