Hi Guys,
As always I have been doing my research and yesterday’s research topic was incontinence following LIS. Now before I continue my CRS assured me that with a good surgeon the risk of permanent incontinence in both men and women is less than 1% (the NHS quote this as 0.5%) so the odds are definitely in your favour.
I did find quite an interesting article about anal resting pressure following LIS, now as you may know a tight sphincter (which causes the spasms) is the main cause of non-healing in anal fissures. Both GTN and Botox perform chemical sphincterotomy’s to relax things however if healing still does not occur then a surgeon will make a small nick in the sphincter (LIS) to permanently relax the sphincter.
So the report I was reading compared anal resting pressures in 50 patients (23 female, 27 male).
The resting pressure was read before LIS surgery, straight after and then at 3, 6 and 12 months.
Resting Pressure 1 month before surgery = 138
Resting Pressure 1 month after surgery = 86
Resting Pressure at 3 months = 95.4
Resting Pressure at 6 months = 102
Resting Pressure at 12 months = 110
What this demonstrates to me is why patients may suffer some mild temporary incontinence immediately following surgery and why CRS’s suggest that full healing occurs in 12 months. It shows that the sphincter is at its weakest immediately following surgery and a constant healing improvement continues over the course of 12 months post surgery.
It is also important to note that during the 1 year follow-up, all the patients were free of symptoms. Only 1 patient (2%) had temporary soiling, which resolved after 3 months. There were no other postoperative complications.
