[Lower gastrointestinal bleeding; a case report]

ABSTRACT

A 40-year-old woman was referred to our health center with a bulky rectorrhagia. The patient was treated with meropenem and vancomycin for an enterococcal meningitis one week earlier. A colonoscopy was performed at a different center, which was unsuccessful due to high blood volume in the colon and poor vision. The patient underwent angiography of the superior and inferior mesenteric arteries and the rectum artery, but the origin of the bleeding was not known. A polypoid mass with ulcer and bleeding from the site was seen in repeated colonoscopy of the left colon reagion. Due to the severity of the bleeding, the patient was transferred to the operating room and a large uterine mass that had transmitted to the lobes of the sigmoid colon was observed. Due to the diagnosis of uterine tumor, hysterectomy and oophorectomy were performed, and the descending colon was removed as a colostomy from the abdominal wall. In the pathological examination, diffuse endometriosis was found, which had involved the left ovary, the left fallopian tube, and both parametrium and sigmoid to the submucosal layer. On the 26th day, the patient was discharged with a good general condition and full vigilance
