Endometriose intestinal: análise descritiva das alterações morfológicas em peças cirúrgicas

Abstract

Endometriosis can affect the intestinal tract in 12% of patients with pelvic endometriosis. Clinically, intestinal endometriosis can masquerade many others more common diseases as regional enteritis, ischemic colitis, self acute colitis, diverticulitis, appendicitis and even colonic cancer. The current study analyses morphological features of intestinal endometriosis from patients that were submitted to surgical resection as disease treatment. 16 patients were identified from Pathology files. Patients age ranged from 24 to 65 years (mean age, 37,9 years). Clinical complaints included abdominal or pelvic pain (7/16), tenesmus (6/16), constipation or painful defecation (4/16), abdominal distension (3/16) and low caliber stool (2/16). Endometriosis were located in rectosigmoid (11/16), appendix (2/16), cecum (01/16), ileum, cecum and appendix (1/16), colon, not otherwise specified (01/16). Endometriotic foci were detected in submucosa, muscularis propria and serosa (62,5%); muscularis propria and subserosa (31,25%) and just muscularis propria (6,25%). Histological findings were: smooth muscle hypertrophy, neural hypertrophy, fibrosis, glandular cystic dilation, hemossiderin deposition and perineural infiltration by endometriotic tissue.
