Hemorrhoids are one of the most common anorectal disorders with a reported prevalence of 4.4% up to 36.4% of general population. The peak prevalence occurs between 45 and 65 years of age. The most common conventional surgical treatment are Milligan-Morgan (open) and Fergusons with electro-cautery hemorrhoidectomy (closed).
Compared with the scissors excision- ligation technique in Milligan-Morgan operation, diathermy and LigaSure™ were reported to have faster recovery and less pain.
The LigaSure™ Vessel Sealing System has been recently introduced as an instrument conceived to upgrade the conventional treatment of haemorrhoids: it consists of a bipolar electrothermal device which offers an optimised combination of pressure and radiofrequency, sealing blood vessels up to 7 mm in diameter and generating an energy tailored to the tissue impedance, with a thermal injury confined to 2 mm over the surgical site. This limited spread reduces anal spasm and allows to perform a bloodless haemorrhoidectomy with reduced postoperative pain and fast healing. Thus this operation can be recommended as the ideal technique because of the potential reduction in tissue trauma.
