Excision and marsupialization versus sinus excision for the treatment of limited chronic pilonidal disease: a prospective, randomized trial

Abstract

The treatment techniques for pilonidal disease are either associated with high recurrence rates or complex procedures. This prospective randomized study compared the outcome of excision and marsupialization technique with sinus excision technique. A total of 40 consecutive patients with limited, chronic pilonidal sinus disease were operated with either excision and marsupialization technique (Group 1, n=20) or sinus excision technique (Group 2, n=20). The demographics, perioperative data, complications and recurrences were recorded. Patient satisfaction was evaluated with a specific questionnaire 16-18 weeks after surgery. Demographic data, preoperative symptoms and the acute disease history were similar between the groups. Operation time, hospital stay and work-off periods were significantly shorter and the number of out-patient procedures was significantly more in Group 2. Although satisfaction scores were similar between the groups, the patients who had no complaint, were "completely satisfied" or would "absolutely recommend the operative technique to other patients" were significantly more in Group 2. In conclusion, the sinus excision technique requires a shorter operation time, hospital stay and work-off period than excision and marsupialization in the treatment of limited, chronic pilonidal disease. The sinus excision technique can be performed as an out-patient procedure in most cases, and seems to be associated with better patient satisfaction.
