Manometric studies in rectal prolapse.

Diseases of the Colon and Rectum

|August 1, 1984

Summary

This summary is machine-generated.

Manometric studies reveal absent or reduced internal sphincter inhibitory reflexes in patients with rectal prolapse. Surgery can restore these reflexes in some cases, but persistent absence may indicate a risk of prolapse recurrence.

Background:

Rectal prolapse is a condition affecting the rectum.
Internal sphincter reflexes play a role in rectal function.

Purpose of the Study:

To investigate internal sphincter reflexes in patients with rectal prolapse.
To assess the impact of surgery on these reflexes.

Main Methods:

Manometric studies were performed on 15 patients (14 with rectal prolapse, 1 with mucosal prolapse).
Preoperative and postoperative manometry were conducted on three patients who underwent anterior resection.

Main Results:

Preoperatively, 12 patients showed absent or obtunded internal sphincter inhibitory reflexes.

Related Experiment Videos

Postoperatively, one patient regained normal reflexes after surgery.

One patient had persistent absent reflexes and recurrent rectal prolapse.

Conclusions:

Internal sphincter inhibitory reflexes are often impaired in rectal prolapse.
Surgical correction may restore reflex function in some patients.
Persistent reflex dysfunction may be associated with recurrent rectal prolapse.
