Introduction: Cutting diathermy is a more recent alternative to scalpel for surgical incisions. Its use was limited due to fear of increased risk of infection, impair healing and decrease cosmesis. However, recent studies suggest otherwise, claiming that diathermy may offer potential advantages with respect to blood loss, incision time and post-operative pain. The aim of this study was thus to evaluate the outcome of diathermic incision in terms of healing, post-op pain and scar characteristics in operations with incisions more than 5 cm in size.

Materials & Methods: A hospital based observational study included 182 cases scheduled to undergo surgery requiring more than approximately 5 cm of incision. Cases were operated by surgeons who have a minimum of 3 years of experience. Incision time, wound healing, post-op pain and scar characteristics were noted at discharge and follow up at 7th and 30th day.

Results: Mean incision time was 24.5 seconds with almost half of the cases (48.9%) had incision time between 20-30 seconds. A significant improvement was observed in all cases regarding mean Southampton wound score and pain score from day of discharge till day 30th of follow up. A significant improvement was also observed in patient and observer scar assessment scale in all the sub categories from day of discharge till day 30th of follow up None of the cases complaint of any surgical site infections or scar related complications.

Conclusion: Electrocautery can be considered as effective and safe in making large skin incision. It is associated with less incision time, faster healing, low post-operative pain and good scar characteristics.
