Hi and thanks for the query,
The spincter has important physioloic roles in the body, and is subject to to respond to nervous and hormonal
signals. It s response to these stimuli are key in maintaining to a large extent a balanced functional state.
Removal it completely, considering the fact that it is still very much performant is not very much justified. I do suggest you stick to the recommendations of your physician. Many people do go through this procedure and lead normal and productive lives. I suggest you stay positive and not so worried. Do not however fail to give timely feedback to your treating physician in case new signs or aggravation f the health is noticed.
Thanks and kind regards.
