Culdoscopy

ALSO KNOWN AS: Flexible culdoscopy

DEFINITION: A culdoscopy is a minimally invasive surgical procedure for visualizing the female pelvic organs through an endoscope (or culdoscope). The endoscope, a rigid viewing tube, is passed through the vagina into the cul-de-sac or rectouterine pouch (the pouch of Douglas), the part of the peritoneal cavity between the rectum and the uterus. The procedure can be used for the diagnosis of diseases such as cancer or the diagnosis of other conditions such as infertility or endometriosis.

Cancers diagnosed: Cancer of the uterus, ovaries, or Fallopian tubes

Why performed: Culdoscopy allows examination of the female pelvic organs and collection of a biopsy (tissue sample) for diagnosing cancer, with minimal discomfort for the patient. Culdoscopy can also be used to assess female fertility and for tubal ligation.

Patient preparation: The procedure is minimally invasive and is usually a hospital procedure with a short stay. Gas distension may be required for visualization, but it may not be necessary if the procedure is done in the knee-to-chest position. Anesthesia required for the procedure may vary from local or regional to general anesthesia, depending on various factors. If a flexible tube is used, the patient may stay awake during the procedure. The patient is informed of the risks involved, as well as the benefits of this type of diagnostic procedure.

Steps of the procedure: The patient can be positioned in the knee-to-chest position or lying down (lithotomy) for this procedure. The endoscope, or culdoscope, is inserted into the female pelvic cavity via a small incision or puncture in the top of the posterior (back) vaginal wall. After the surgeon visualizes the pelvic cavity, a tissue sample may be taken and sent to the laboratory to determine the presence of cancer.

After the procedure: The patient may be positioned on her abdomen to help expel any air used in the procedure. The patient is assessed and monitored for bleeding from the vagina. The patient should abstain from sexual intercourse, tampon use, or douches for at least two weeks or until cleared through her health care provider.

Risks: Bowel injury and sepsis are possible risks of culdoscopy. Complications are estimated at 2 percent of patients and include bleeding at the puncture site, infection or peritonitis, or hypersensitivity or allergic reaction to the anesthetic used in the surgery.

Results: Though culdoscopy is still used as a diagnostic tool, many healthcare providers have replaced it with laparoscopy. Its use in the United States began to fade after the 1970s, although it experienced a resurgence in the twenty-first century. Some medical professionals prefer culdoscopy since no abdominal incision is required, as with laparoscopy. The procedure is still performed because the findings of culdoscopy are often comparable to those of laparoscopy
