Endometriosis -rare cause of small bowel obstruction

Introduction: Endometriosis is a disease where endometrial tissue grows outside the uterus. The endometrial tissue gets deposited over extra-uterine place like ovaries, fallopian tubes, pouch of Douglas, bowel, pelvis and ureter. Younger female patients are more prone to develop this problem andmainly presents with chronic pelvic pain, infertility and non- specific complaints like dysmenorrhea, dyspareunia and change in bowel habits. Diagnosis of endometriosis is based on symptoms and imaging. But tissue biopsy is diagnostic of endometriosis.
Case report: In our case report, 43-year-old female presented in OPD with complaint of features suggestive of intestinal obstruction. CECT abdomen suggested bilateral ovarian endometriosis and inflammatory thickening in distal small bowel possibly endometrial deposits. She underwent laparotomyand resection anastomosis done for dense thick stricture in proximal ileum mimicking malignancy. Histopathology report suggested endometriosis of stricture segment with adhesions.
Conclusion: Small bowel obstruction due to endometriosis is rare and we can make differential diagnosis in younger fertile female with history of chronic pelvic pain.
