Culdoscopy is an endoscopic procedure performed to examine the rectouterine pouch and pelvic viscera by the introduction of a culdoscope through the posterior vaginal wall.

[3] A trocar is first inserted through the vagina into the posterior cul-de-sac, the space behind the cervix, allowing then the entry of the culdoscope.

Conditions diagnosable by culdoscopy include tubal adhesions (causing sterility), ectopic pregnancy, and salpingitis.

[4] Culdoscopy is performed with the patient in a knee chest position under local or general anesthesia.

[citation needed] The procedure was inaugurated by Albert Decker in 1939[3] and became popular after his reported experience in 1944.
