| Summary: | Patients with preservation of the transitional zone of the anal
canal have less leakage and less need to wear pads than patients who have had
mucosectomy. There is a significant difference in mean maximum resting pressure
between patients that have had anal transitional zone preservation and
mucosectomy. With preservation of the anal transitional zone, a mean maximum
resting pressure of 57.6±3.8 mmHg was obtained compared with 47.3±4 mmHg
in the mucosectomy group. Preservation of the resting pressure is dependent on
preservation of internal anal sphincter integrity. The integrity of the sphincter
is injured during mucosectomy due to anal dilation. Other factors affecting
continence and stool frequency, such as diet, antidiarrheal medications, stool
consistency and compliance, when examined were found to be unrelated factors. |
