A randomized study between excision and marsupialization and radiofrequency sinus excision in sacro-coccygeal pilonidal disease. Current Surgery, May - June 2004 Gupta PJ. Gupta Nursing Home, Nagpur, India. BACKGROUND: The surgical approach to pilonidal sinus disease is open to debate. This prospective, randomized study was aimed to compare the outcome of the excision and marsupialization and the sinus excision technique by radiofrequency. MATERIALS AND METHODS: Thirty patients of chronic pilonidal sinus disease were randomly assigned to radiofrequency sinus excision (n = 15) and excision and marsupialization (n = 15). The parameters measured included intraoperative and postoperative data, wound-related complications, and recurrence. Patient satisfaction score was assessed at 1-year follow-up. RESULTS: The operation time, postoperative pain, hospital stay, and off work periods were significantly less (p < 0.05) in the technique employing radiofrequency surgery. At 1-year follow-up, there was 1 case of recurrence in each group. The patients from radiofrequency group expressed better satisfaction than the patients operated by marsupialization. CONCLUSION: Radiofrequency sinus excision technique needs a shorter hospital stay with reduced postoperative pain and early resumption to work in comparison with the sinus excision and marsupialization technique.
