N80.55
Endometriosis of other parts of the colon
Clinical Classification Guidelines
Inclusion Terms
- Endometriosis of descending colon
- Endometriosis of transverse colon
Medical Intelligence & Overview
Endometriosis of the colon, specifically the descending and transverse parts, is a condition where tissue similar to the lining inside the uterus (endometrial tissue) grows outside the uterus and affects parts of the large intestine. Classified under ICD-10 code N80.55, this condition can cause various symptoms related to bowel and pelvic health. Although it commonly occurs in reproductive organs, endometrial tissue can also be found on other pelvic and abdominal structures, including sections of the colon. This form of endometriosis can be particularly challenging to diagnose because its symptoms often mimic other gastrointestinal or gynecological issues.
Causes & Symptoms
Clinical Causes: Retrograde menstruation: Endometrial tissue flows backward through the fallopian tubes into the pelvic cavity during menstruation. Genetic predisposition: Family history of endometriosis increases risk. Immune system disorders: Abnormal immune responses may prevent the body from destroying misplaced endometrial tissue. Hormonal factors: Estrogen promotes the growth of endometrial tissue outside the uterus. Lymphatic or vascular spread: Endometrial cells may travel through lymphatic channels or blood vessels to reach the colon.
Key Symptoms: Lower abdominal or pelvic pain, especially during menstruation or bowel movements Pain during or after defecation Bloating or feeling of fullness in the abdomen Nausea or gastrointestinal discomfort Pain during sexual intercourse (dyspareunia) Changes in bowel habits, such as diarrhea or constipation Occasional bleeding or spotting, if the endometrial tissue involves the intestine directly
Diagnostic & Treatment
Diagnosis Path: Medical history assessment: Discussing symptoms and menstrual cycle patterns Pelvic examination: Checking for masses or tenderness Imaging tests: Ultrasound or MRI to identify cysts or masses Colonoscopy: Visualizing the interior of the colon to identify lesions or abnormal tissue Biopsy: Taking tissue samples during endoscopy or laparoscopy for microscopic examination to confirm endometrial tissue Laparoscopy: Minimally invasive surgical procedure to directly observe/retract endometrial implants and perform tissue sampling
Treatment Protocols: Pain management: Use of analgesics to control discomfort Hormonal therapy: Suppressing estrogen production to reduce endometrial tissue growth (e.g., hormonal contraceptives, GnRH agonists) Surgical intervention: Removal or excision of endometrial tissue from the colon and surrounding areas Lifestyle modifications: Dietary adjustments and physical therapy to alleviate symptoms Monitoring and managing symptoms: Regular follow-up to adapt treatment plans as needed
