Colonic endometriosis must be differentiated from Crohn’s disease, diverticular disease, adhesions, or neoplasm. Although colonic endometriosis may be asymptomatic, it can also present as large bowel obstruction. Differential diagnosis must be made with irritable bowel syndrome, solitary rectal ulcer syndrome and a rectal tumor. Rectal involvement may result in alterations in bowel habits such as constipation, diarrhea, dyschezia, tenesmus, and, rarely, rectal bleeding. Chronic pelvic pain, often more severe during menstruation or at ovulation, is the most common symptom associated with endometriosis. Moreover, physical examination, especially vaginal examination, may be completely normal, which hampers the diagnosis in young females. Symptoms of endometriosis can be non-specific with considerable overlap with other clinical conditions, delaying a diagnosis and treatment. ![]() Intestinal symptoms due to endometriosis may vary depending on location and menstrual cycle. In women with moderate to severe disease, some degree of intestinal symptoms may be present. For these patients, the clinical course appears to be benign, and surgical resection is probably not indicated, especially when there is no associated infertility. Even women with bowel endometriosis may be asymptomatic. The natural history of the disease has never been well defined due to the asymptomatic nature of the disease in many women. In general, the most common presenting clinical features are pelvic pain and infertility. The term “bowel endometriosis” should be used when endometrial-like glands and stroma infiltrate the bowel wall reaching at least the subserous fat tissue or adjacent subserous plexus. The histopathological diagnosis of endometriosis is usually straightforward. Endometriosis affects the bowel in 3%-37% of all cases, and in 90% of these cases the rectum or sigmoid colon are also involved. About one-third of infertile women suffer from endometriosis. It is estimated that up to 15% of all women of reproductive age have endometriosis. Long-term outcomes, following bowel resection for severe endometriosis, regarding pain and recurrence rate are good with a pregnancy rate of 50%.Įndometriosis occurs during the active reproductive period. Depending on the size of the lesion and site of involvement, full-thickness disc excision or bowel resection needs to be performed by an experienced colorectal surgeon. Multidisciplinary laparoscopic treatment has become the standard of care. A precise diagnosis about the presence, location, and extent of endometriosis is necessary to plan surgical treatment. Differential diagnosis must be made in case of irritable bowel syndrome, solitary rectal ulcer syndrome, and a rectal tumor. ![]() Colorectal involvement results in alterations of bowel habits such as constipation, diarrhea, tenesmus, dyschezia, and, rarely, rectal bleeding. The frequency of bowel endometriosis is unknown, but in cases of bowel infiltration, about 90% are localized on the sigmoid colon or the rectum. This type of endometriosis is mostly found on the uterosacral ligaments, inside the rectovaginal septum or vagina, in the rectosigmoid area, ovarian fossa, pelvic peritoneum, ureters, and bladder, causing a distortion of the pelvic anatomy. Deep endometriosis is defined as endometriosis located more than 5 mm beneath the peritoneal surface. Up to 15% of women in their reproductive period are affected by this condition. Preoperative tumor embolization is an example of this.Endometriosis is a gynecological condition that presents as endometrial-like tissue outside the uterus and induces a chronic inflammatory reaction. ![]() In other cases the endovascular treatment is preoperative prior to open neurosurgery. Many of the treatments are performed entirely endovascularly (inside the vessels), with no other treatment necessary. Also known as endovascular neurosurgery, neurointerventional surgery, endovascular surgical neuroradiology and interventional neuroradiology, neuroendovascular surgery involves advancing small hollow tubes (catheters) and small devices through arteries and veins. Neuroendovascular surgery (NES) is an innovative, minimally-invasive surgical treatment for complex brain and spinal cord vascular diseases that is performed from inside the blood vessels.
