Wow Suavecito! It sounds like you have been through quite the ordeal for that period of time. I know what you mean about getting constipated due to the spasming muscle. I too have had that issue. I have to say that I am surprised and concerned that your surgeon did not try you on an ointment first as this is nearly always standard protocol before surgery. These ointments will relax the internal sphincter as well and increase blood flow to the area. There are never any guarantees with any surgery and there are aways risks. Is this surgeon a colorectal surgeon? You will want to make sure they are very experienced with this surgery. You didn't mention the consistency of your stools. Many on here have had great success with stool softeners to keep the BM damage to a minimum.

Hey M, I was offered nitro cream but decided against it. I can count the number of headaches Ive had in my life on both hands, but when I do get one, its horrible. Also, the surgeon that did the colonoscopy warned against it because of all the side effects. After reading up on the side effects, i decided to tough it out. I havent taken any meds throughout this whole ordeal because my doc said pain meds cause hard stools and can thin the blood. Since there has been blood streaks in my stool, I dont want to use those either. I have used stool softners, fiber chews, metamucil, and probiotic supplements the last week to try and figure out my stomach issues because regularity is not my strong point. Thanks for your help.

There are some other non-nitro creams - for example, nifedipine lidocaine or ditalizm (sp?).
LIS does have a 98% success rate. In terms of it being a permanent, I suppose if it works, and it heals the fissure, then you have a permanent fix to that particular fissure, but I don't think it prevents you from getting another fissure in the future. I suppose it does lessen the spinchter muscle tone for at least a while, so it could also allow future fissures more time to heal...

For what it is worth, I had LIS done and it did not help.
