RADIOFREQUENCY ELECTROCAUTERY OR BOVIE
Simultaneous cut and coagulation. Requires different modes and adjustments for different applications.
Minimal smoke production. Produces excessive smoke.
Minimal surrounding tissue damage. Tissue damage like 3rd degree burns.
Heats tissues below 10000C. Raises tissue temperature above 50000C.
Sterilizes tissues under application. Can cause postoperative sepsis.
Minimal scarring creates soft supple scar. Gross scarring and fibrosis.
Faster healing. Slow healing.

RADIOFREQUENCY CRYOSURGERY
Tissue interaction can be
predetermined with power
setting selection.
Difficult to achieve precise
tissue destruction.
No tissue adherence
or charring.
Probes often stick to the site of
application and cause detachment
of the tissue with bleeding.
Minimal postoperative edema and discharge. Extensive edema and profuse discharge from the treated area.
Result is immediately visible. Uncertainty of result due to
variable tissue response.
Multiple uses in proctology. Used for the treatment
of hemorrhoids alone.

RADIOFREQUENCY LASER
Adaptable for multiple uses in
proctology.
Limited applications in proctology
surgery.
Equally effective for cutting and coagulation. Good cutting effect but poor coagulation.
Unit cost much less. High instrument cost.
Portable. Limited mobility.
Inexpensive treatment. Costly treatment.
Easy anal canal access due to variable electrodes. Limited access in the anal canal.
Faster healing. Risk of misdirected reflected beam and delayed wound healing.

Other advantages of radiofrequency surgery -
Radiofrequency surgery allows cutting without pressure and consequently, there is little tissue damage and minimal scarring24. The electrode tip is sterile, as is all the tissue being exposed to it25. Healing is by granulation, with a soft and supple scar26. It could be performed with ease even in the depth and in difficult areas like the anal canal. There are minimal incidences of postoperative infection, thereby achieving faster wound healing with negligible use of sutures etc.

The electrodes are reusable and may be kept in cold sterilization solution when not in use.

Conclusion
Use of radiofrequency in performance of various proctology surgeries results in less trauma to the cells, less fibrous scarring and less postoperative discomfort. The procedures are cost effective as no expenses of recurring nature are incurred. The radiofrequency tool having a versatile use in various surgical procedures can prove handy for the practicing surgeons.
