In some patients after Hemorrhoidectomy, sphincter
injury can occur.
Despite success with slings in a select group of patients, i.e., those with low preoperative pad weights, appropriate external sphincter
coaptation on preoperative cystoscopy, and no history of prior radiation or urethral surgery, there are many patients who do not fit these criteria and are better served with AUS.
The magnetic attraction between the beads augments the existing esophageal sphincter
's barrier function to prevent reflux.
When an anatomic defect is present in the anal sphincter
and conservative treatment has not been successful, surgical correction is preferred.
 in their study on twins though found no significant difference in preprandial BLESP in symptomatic versus asymptomatic subjects but found significantly lower postprandial BLESP in symptomatic versus asymptomatic twins with no difference in peristaltic amplitude, LES length, or transient lower esophageal sphincter
Slowly absorbable or nonabsorbable sutures were considered appropriate for sphincter
(31) Therapy generally has 3 components: exercising the external sphincter
complex, training in the discrimination of rectal sensations, and developing synchrony of the internal and external sphincter
responses during rectal distension.
These functions are performed by coordinated actions between the detrusor and the urethral sphincter
under the control of brain and lumbosacral spinal cord (Groat et al., 1993).
Nevertheless they were able to induce regeneration of the mouse's own urethral sphincter
But now, according to Professor Khalil Bitar, one of the lead researchers involved in the work mentioned above, "In essence, we have built a replacement sphincter
that we hope can one day benefit human patients.
Obstetrical anal sphincter
laceration is a known risk factor for AI.
This can be achieved by bypassing the sphincter
, using an indwelling urethral or suprapubic catheter or creating a stoma.
