Sigmoidocele

From Wikipedia, the free encyclopedia

Sigmoidocele (also known as Pouch of Douglas descent) refers to a condition where the sigmoid colon descends (prolapses) into the lower pelvic cavity. ^[1] This can obstruct the rectum and cause symptoms of obstructed defecation.

Epidemiology

Sigmoidocele normally occurs in females, and is uncommon. ^[1]

Pathophysiology

The phenomena is caused by a weak section of fascial supports of the vagina (the uterosacral cardinal ligament complex and rectal vaginal septum), which allows a section of peritoneum containing the sigmoid colon to prolapse out of normal position and fall between the rectum and the vagina. ^[2]

Diagnosis

It is not possible to differentiate between a rectocele and a sigmoidocele on vaginal examination. Defecating proctography will demonstrate a sigmoidocele during straining.
