Brief Summary

Perianal condyloma are skin- colored and fleshy lesions caused by various variants of Human Papilloma Virus (HPV), most commonly 6 and 11. The treatment modalities available include topical options like podophyllin, imiquimod cream, trichloroacetic acid and cryotherapy, injectable options like interferon and 5-fluoroucil, and surgical options like excision, fulguration, cryotherapy, and laser removal. However, the treatment is usually short-lived, and the patients are subjected to multiple repeat procedures because of high recurrence and low clearance rates. Surgical management has the highest clearance rate. There are several surgical modalities including excision, electrosurgical fulguration (ESF), and LASER vaporization. LASER techniques work directly to destroy/transect the lesion, cause necrosis of infected keratinocytes and induce local inflammation. LASER treatment is also reported to have minimal local surrounding tissue injury and sphincter injury, and less pain and discomfort. For this reason, LASER therapy has been increasingly used to remove anogenital warts, and is a standard of care treatment of condyloma. We hypothesize that LASER vaporization is effective to treat perianal condyloma and may have clinical benefits over ESF. We will compare postoperative outcomes such as pain, healing, cosmesis and recurrence following either treatment method.

Study Groups

CO2 LASER Vaporization Group

Group Type: EXPERIMENTAL

CO2 LASER Vaporisation

Intervention Type: PROCEDURE

The CO2 LASER vaporization procedure is described as follows. Patient positioning will be done, and patient will be anesthetized. Local infiltration with 2% lidocaine, nerve block or general anesthesia will be given. The surgical field will be disinfected and draped. The perianal and anal area will be investigated for lesion. CO2 LASER from 20 cm distance in a continuous wave mode and 20 W power will be applied. After warts melts, necrotic tissue will be removed. After the operation was completed, residual debris will be wiped away with a piece of moist gauze. Bacitracin cream applied over the treated areas. Upon discharge acetaminophen 1-gram q8 and Ibuprofen 600 q8 for pain.

Electrosurgical Fulguration Group

Group Type: ACTIVE_COMPARATOR

Electrosurgical Fulguration

Intervention Type: PROCEDURE

The procedure is described as follows. Patient will be administered regional or general anesthesia, placed in prone jack-knife position. Prepping and draping will be done. The perianal and anal area will be investigated for lesion. The lesions will be excised, and the bases will be fulgurated. Electrosurgery device will be used in monopolar setting (30 Cut mode, 30 Coag mode). After procedure local analgesics total MERCAINE/EPI 0.25% 20 ml on both sides of the lesion. Bacitracin cream applied over the treated areas. Upon discharge 1000 mg of Tylenol every 8 hours along with 600 mg of ibuprofen every 8 hours.
