Transvaginal repair of rectocele for obstructed defecation syndrome: a case report.

Rectocele (RC), defined as the protrusion of the anterior rectal wall into the vaginal lumen, is a significant cause of obstructed defecation syndrome (ODS). This case report describes a 60-year-old female patient with chronic constipation diagnosed with Grade III RC-induced ODS after excluding organic bowel diseases and slow-transit constipation. The patient underwent transvaginal repair of the RC, resulting in significant clinical improvement. Combined with a review of the literature, this article discusses the diagnostic criteria, surgical indications, and treatment strategies for RC, providing valuable insights for clinical practice.
