Postoperative pain is one of the most common and disabling complications following hemorrhoidectomy. This study divided a
total of 90 patients, undergone Milligan and Morgan hemorrhoidectomy, in three groups of 30 patient: Group A, undergone internal
sphincterotomy after hemorrhoidectomy; Group B, treated with Diosmin 500 mg; Group C, treated with Paracetamol 1000 mg when
required. The analysis of the median VAS score (Visual Analogic Scale) of postoperative pain, in every group pointed out a relationship
between postoperative pain reduction and time at the three set checkpoints (1st, 3rd, 9th postoperative day) (R2= 0.9231 for
Group A; R2= 0.9423 for group B; R2= 0.9423 for group C). Mean VAS scores have been worked out for the three checkpoints and
we compared the results between the three groups.
Conclusions: in our study, internal sphincterotomy was the only therapeutic choice able to reduce most of the others the postoperative
pain, both the 1st, the 3rd and the 9th postoperative day
