Well, my "dear" CRS explained that he did fissurectomy to avoid that...That edges sometimes overlap and leave space under that can form abscess and fistula- I still wish he didn't do that : ((((...
Mine fissure lasted 5 months, healed than opened again after 2-3 weeks and I just had enough of it and decided to have LIS . I am 2 weeks post-op - still recovering. Since I had fissurectomy too, I will need at least 8 weeks to fully recover.
BEST OF LUCK
