To answer your questions:
1) It would depend on the cause leading to the lack of peristalsis. If it is a treatable cause (i.e. metabolic causes like diabetes or thyroid disorders), then perhaps. However, with some neuromuscular diseases, there is the possibility that it would not improve.
2) With laxative abuse, there is no clear way to determine if the symptoms would improve, and prognosis would vary from patient to patient.
3) Surgery is the most definitive treatment for chronic constipation. If this avenue is considered, then a colostomy bag can be possibility.
These options can be discussed with your personal physician.
Followup with your personal physician is essential.
