The rectouterine (or recto-uterine) pouch is also called the rectouterine excavation, uterorectal pouch, rectovaginal pouch, pouch of Douglas (after anatomist James Douglas, 1675–1742), Douglas pouch, [6] Douglas cavity, [6] Douglas space, [6] Douglas cul-de-sac, [6] Ehrhardt–Cole recess, Ehrhardt–Cole cul-de-sac, cavum Douglasi, or excavatio rectouterina.
The thecal sac or dural sac is the membranous sheath (theca) or tube of dura mater that surrounds the spinal cord and the cauda equina. The thecal sac contains the cerebrospinal fluid which provides nutrients and buoyancy to the spinal cord. [ 1 ]
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. [1] The word culdoscopy (and culdoscope) is derived from the term cul-de-sac, which means literally in French "bottom of a sac", and refers to the rectouterine pouch (or called the pouch of Douglas).
Cul-de-sac hernias usually only appear on such imagining at the end of the simulated defecation, and require complete or near complete evacuation of the rectum before they are visible. [3] This feature may distinguish cul-de-sac hernia from rectocele. [1] However, a large rectocele that retains contrast medium may hide a cul-de-sac hernia. [3]
The word culdoscope (and culdoscopy) is derived from the phrase cul-de-sac, which in French literally means "bottom of a sac", here referring to a blind pouch or cavity in the female body that is closed at one end, that is the rectouterine pouch. As early as the 13th century, a cul-de-sac was a dead-end street (or a dead-end way), a blind alley ...
However, this space becomes significant in conditions in which fluid collects within the abdomen (most commonly ascites and hemoperitoneum). The intraperitoneal fluid, be it blood, ascites, or dialysate , collects in this space and may be visualized, most commonly via ultrasound or computed tomography (CT) scanning.
In supine patients, infected fluid from the right iliac fossa may ascend in the paracolic gutter to enter the lesser sac. In patients nursed in a sitting position, fluid from the stomach, duodenum, or gallbladder may run down the paracolic gutter to collect in the right iliac fossa or pelvis. This may mimic acute appendicitis or form a pelvic ...
a deep cul-de-sac [3] [5] levator diastasis [3] [5] a patulous, weak anal sphincter [3] [5] Some authors question whether these abnormalities are the cause, or secondary to the prolapse. [3] Other predisposing factors/associated conditions include: pregnancy [3] (although 35% of women who develop rectal prolapse are nulliparous) [3] (have never ...
