NCT01662765

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.

Outcome Measures

Primary Outcomes (1)

  • Cure Rate

    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.

    2 year after initial treatment

Secondary Outcomes (2)

  • Healing Time

    two year

  • Visual Analogue Scale for Patient Satisfaction (VAS-PS)

    30 days

Other Outcomes (1)

  • Costs

    two year

Study Arms (2)

Surgery

EXPERIMENTAL

Circular incision 2-3 mm below the skin level in the umbilicus through the subcutaneous fat towards the linea alba. Dissection of the subcutaneous tissue within the umbilicus and its deep connection to preperitoneal fat through the linea alba. Excision of the umbilical complex containing pilonidal cyst 3 mm below the umbilical ostium. Approximation of the subcutaneous tissue with a single purse-string absorbable suture. The specimen, including the umbilical complex (pilonidal cyst, and involved skin and subcutaneous tissue), was transferred to department of pathology for histopathological examination.

Procedure: Surgery

Conservative

ACTIVE COMPARATOR

Conservative treatment described as follow: Under local anesthesia, extracting all protruding hair, and curetting the granulation tissue and pilonidal cyst deep in the umbilicus. postoperative management include antibiotic treatment with ampicilline plus sulbactam and ornidazole, shaving surrounding skin, washing twice daily, and keeping umbilicus dry.

Other: conservative

Interventions
