What is the Perirectal space?

What is the Perirectal space?

The retroperitoneal space lying lateral to the rectum on either side is known as the pararectal space. Pararectal spaces take the shape of a curve of sacrum bone. 3 The roof of the pararectal space comprises the posterior leaf of the broad ligament.

What is the parametria?

(payr-uh-MEE-tree-um) The fat and connective tissue that surrounds the uterus. The parametrium helps connect the uterus to other tissues in the pelvis.

What is Pararectal dissection?

The pararectal space is the potential space bordered medially by the rectum, superiorly by the sacral hollow, and inferiorly by the cardinal ligament, containing the uterine artery. This space can be utilized to aid in the dissection of the obliterated posterior cul-de-sac and restoration of normal anatomy.

Is the presacral space in the peritoneal cavity?

The presacral space starts from the parietal peritoneal reflection at the rectosigmoid junction to the pelvic bottom, which contains fatty tissue, lymph nodes, nerve plexuses and blood vessels, median sacral vessels (the artery is from the aorta) and superior rectal vessels (the artery is from the inferior mesenteric …

What is the space of retzius?

The Retzius space is a part of the extraperitoneal space, between the pubic symphysis and the urinary bladder, often referred to as retropubic or antero-vessical, paravesical and pararectal, retropubic space, cave of Retzius, space of Retzius, or Retzius cavity.

What is Subperitoneal?

The term subperitoneal refers to tissue that is deep to the peritoneum and includes the extraperitoneal space, the ligaments and the mesenteries and their suspended organs (Fig. 2A). Organs whose surfaces are covered by peritoneum are therefore subperitoneal.

What is the Mesometrium?

The mesometrium is the largest portion and extends laterally from the entire surface of the uterus. The mesosalpinx is the fold of peritoneum draping over both uterine tubes, and the mesovarium is the fold attaching the anterior portion of each ovary to the posterior part of the broad ligament.

What is Douglas pouch?

The pouch of Douglas (cul-de-sac) represents the caudal extension of the peritoneal cavity. It is the rectovaginal pouch in the female and the rectovesical pouch in the male. The cul-de-sac is in a dependent position when either upright or supine; it is, therefore, a frequent location for seeded lesions.

How do you open retroperitoneal space?

The round ligament is the key to exposing the retroperitoneal space. It should be open at the pelvic sidewall, just medial to the external iliac vessels. The umbilical ligament can be used as a landmark. The divided round ligament is retracted ventrally and medially to place the ovarian vessels under traction.

What is a presacral space lesion?

Presacral tumors are a rare group of heterogeneous lesions located in a potential space referred to as the retrorectal or presacral space. Lack of characteristic symptomatology and difficult anatomical localization make the diagnosis and management challenging for a surgeon.

Where is the presacral space located?

The presacral space is an extraperitoneal potential space between the upper two-thirds of the rectum and the sacrum.

What is space of Bogros?

The retroinguinal space (or Bogros’ space) is the extraperitoneal space situated deep to the inguinal ligament. It’s limited by the fascia transversalis anteriorly, the peritoneum posteriorly and the iliac fascia laterally. This preperitoneal space communicates with prevesical space of Retzius.

What is found in the retropubic space?

Retropubic space is a potential avascular space located between the pubic symphysis and the urinary bladder. The retropubic space is a preperitoneal space, located behind the transversalis fascia and in front of peritoneum .
…

What is the Subperitoneal space?

The subperitoneal space is a continuous interconnecting space beneath the peritoneum containing the extraperitoneal space, the ligaments and mesenteries, and their suspended organs. Individual mesenteries and ligaments are identified by the vessels that course through them.

What is the Subhepatic space?

Description. The subhepatic space lies between the liver and transverse colon or left kidney, and the stomach and the lesser omentum. The part of the subhepatic space between the liver and left kidney is called the hepatorenal recess (Morison’s pouch)

What is the mesosalpinx?

The mesosalpinx is the fold of peritoneum draping over both uterine tubes, and the mesovarium is the fold attaching the anterior portion of each ovary to the posterior part of the broad ligament. The mesovarium does not cover the entire surface of each ovary but helps to keep its position within the pelvis.[4][5]

What is rectovesical pouch?

Medical Definition of rectovesical pouch

: a sac between the rectum and the urinary bladder in males that is formed by a folding of the peritoneum — compare rectouterine pouch.

Why is it called pouch of Douglas?

The pouch of Douglas is an anatomical structure named after the Scottish anatomist James Douglas. It is a bag-shaped extension of the peritoneum (a membrane that lines the insides of the abdomen and pelvis) located between the posterior wall of the uterus and the rectum.

What does retroperitoneal mean?

Listen to pronunciation. (REH-troh-PAYR-ih-toh-NEE-ul) Having to do with the area outside or behind the peritoneum (the tissue that lines the abdominal wall and covers most of the organs in the abdomen).

Why is the retroperitoneal space necessary?

The retroperitoneal space provides access to the lumbar plexus, origin and course of peripheral nerves, and the lateral lumbar spine as well as the ventrolateral spinal canal.

Where is the Retrorectal space?

CLINICAL ANATOMY AND PHYSIOLOGY
The retrorectal space lies above the presacral fascia, between the upper two-thirds of the rectum and sacrum. This site contains totipotential cells, and is where fusion of the embryologic hindgut and the neuroectoderm occurs.

Where is a presacral mass?

Presacral tumors are rare tumors that develop in the area between the rectum and the bottom portion of the spine (sacrum). Also described as retrorectal, this area is normally either empty or contains only fat.

What is retropubic space?

The retropubic space is also called the pre-vesical space or the space of Retzius. It can be visualised after opening the fold of peritoneum between the bladder and the anterior abdominal wall. It is bounded anteriorly by the pubic symphysis and the superior pubic ramus laterally.

Where is retropubic space located?

The retropubic space (also known as the prevesical space, cave of Retzius or cavum Retzii) is an extraperitoneal space located posterior to the pubic symphysis and anterior to the urinary bladder. It is separated from the anterior abdominal wall by the transversalis fascia and extends to the level of the umbilicus.

What is the UV fold?

The uterovesical fold is the anterior peritoneal fold which reflects from the junction of the uterine body and cervix onto the bladder. It creates the uterovesical pouch, which occurs anteriorly between the bladder and uterus.
