Hemorrhoidal (mucosal) prolapse is common (see discussion under Hemorrhoids). Full thickness is uncommon and is usually caused by surgical or traumatic injuries or from chronic, excessive straining at stool in conjunction with weakening of pelvic support structures, especially in patients who are older, psychotic, or paraplegic. Although prolapse initially reduces spontaneously after defecation, with time the rectal mucosa becomes chronically prolapsed, resulting in mucous discharge, bleeding, incontinence, and sphincteric damage. Patients with complete prolapse require surgical correction. SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/03/29 UR - accessmedicine.mhmedical.com/content.aspx?aid=1193152078 ER -
