Two groups of 16 patients each were studied. All were operated on for prolapsed and thrombosed haemorrhoids. One group was subjected to the typical Milligan-Morgan haemorrhoidectomy, while in the other an internal sphincterotomy was carried out in addition to haemorrhoidectomy. This was done in an effort to determine the effect of internal sphincterotomy on the reduction of postoperative pain. We were pleased to note a definite beneficial effect from the addition of sphincterotomy in patients aged under 40 years, although we found no significant difference in older patients.
