Technology Meets Tradition: CO2 Laser Circumcision versus Conventional Surgical Technique.

Abstract

PurposeWe wished to present the clinical applications and to evaluate the benefits of the use of a carbon dioxide (CO2) laser versus the conventional procedure for circumcision in adults, in terms of duration of surgery, surgical techniques, complications, pain and cosmetic appearance.Patients and MethodsThe medical records of 482 patients who had been circumcised were retrospectively evaluated. The patients were divided into two groups: 168 patients (Group A) were circumcised with traditional techniques; and 314 patients (Group B) were circumcised using a CO2 laser. All the patients were circumcised under local anesthesia. Pain was evaluated using a verbal numerical rating scale for pain assessment. Postoperative wound swelling, bleeding, infection and pain were assessed at 4 hours, 24 hours and 7 days after surgery.ResultsThere were no significant differences between the two groups in terms of bleeding and infections. The difference in operating times between the groups was significant (p<0.001). Wound disruptions occurred in one patient in Group A at 3 days and two patients in Group B at 1 week. Pain scores were low and there was less pain in Group B than in Group A during the first 4 hours (1.8 vs 3.7; p<0.002). Compared with the conventional method, the CO2 laser technique was associated with much less pain at both 1 day (p<0.002) and 7 days (p<0.001) postoperatively. The cosmetic results were superior in Group B; a linear surgical scar developed in 94.9% of patients in Group B versus 61.3% in Group A (p<0.001).ConclusionOur results show that the use of a CO2 laser was associated with a shorter operative time, less wound irritation and better cosmetic appearance compared with standard surgical techniques for circumcision.
