AIM: Milligan-Morgan operation is still considered the treatment of choice for IV-degree haemorrhoids: it is frequently associated with significant postoperative pain and prolonged hospital stay. Many instruments were conceived to reduce these complications, such as the LigaSure™ (LS) system, a combination of radiofrequency and pressure that seems mainly effective where a large tissue demolition is required. This randomized study is METHODS:Fifty-two patients with IV-degree hemorrhoids were randomly assigned to two different surgical treatments (conventional diathermy vs. LigaSure™ hemorrhoidectomy). They were evaluated on the basis of the following main outcomes: mean operative time, postoperative pain, day of discharge early and late complications. The time of recovery of work was also assessed. All patients had a minimum follow-up of twelve months (range 12-24). All data were statistically evaluated.
RESULTS:Twenty-seven patients were treated by conventional diathermy, 25 by LigaSure™. The mean operative time was significantly shorter in LS, such as postoperative pain, mainly lower on the third and fourth postoperative day: moreover pain disappeared earlier in LS than CD. The time off-work was shorter in LS, while there was no difference in hospital stay and overall complications rate .
CONCLUSION:This randomized prospective controlled trial confirms, according to other large trials in literature , the benefits of the LigaSure™ hemorrhoidectomy over conventional diathermy when a large tissue demolition is required, supporting the use of this device as treatment of choice in IV degree hemorrhoids, even if the procedure is more expensive than conventional operation.
