This structure, which is designed to replace a tracheal segment, must be sufficiently rigid to support the proximal insertion of a
neosphincter that opens during respiration and closes during the passage of a food bolus and, at best, would include phonatory capabilities.
Basic anatomical investigation of semitendinosus and the long head of biceps femoris muscle for their posible use in electrically stimulated
neosphincter formation.
The gracilis
neosphincter operation is no longer performed in North America, Dr.
American Medical Systems (AMS), Minnetonka, MN, announced an FDA advisory panel has recommended approval of its Acticon
Neosphincter, an implantable device designed to imitate the function of the sphincter muscle and help prevent uncontrolled bowel movements.
When surgical treatment is warranted, options include occlusion, sphincteroplasty,
neosphincter, radio-frequency energy, and fecal diversion.
The Acticon
Neosphincter is another device that is gaining popularity for surgical treatment of fecal incontinence.
Basic anatomical investigation of semitendinosus and the long head of biceps femoris muscle for their possible use in electrically stimulated
neosphincter formation.
Chronic diarrhea or constipation must be corrected before the Acticon
neosphincter goes in, explained Dr.
The Acticon
neosphincter is marketed in Europe and has been approved by the Food and Drug Administration.
Only 11% of participants were able to defer defecation preoperatively, compared with more than 80% postoperatively Perhaps most impressive was the finding that more than 70% of patients rated their quality of life favorably following receipt of the Acticon
neosphincter, compared with just 19% before.
The mean score among
neosphincter users fell from 105 at baseline--indicative of daily incontinence--to 48 at 1 year, which equates to seepage only.
