Incomplete Small Bowel Obstruction Due to Isolated Ileal Endometriosis: A Mimic of Tuberculosis.

Endometriosis is an estrogen-dependent disease characterized by the presence of functional endometrial tissue outside the uterus. It can be intraor extraperitoneal. Intraperitoneal disease usually is genital and commonly involves the ovaries, uterine ligaments, fallopian tubes, pelvic peritoneum and pouch of Douglas [1]. The most common site of extragenital endometriosis is the gastrointestinal tract (GIT), the other sites being the omentum, peritoneum and occasionally other intra-abdominal organs. Extraperitoneal disease may be seen in the cervix, vagina, abdominal scars and hernia sacs, and is uncommon. Rarely, endometriosis affects the urinary system, lungs, skin, diaphragm and central nervous system [1, 2]. The GIT is involved in 3–37 % of the females with endometriosis; the most common site being the rectosigmoid colon (72 %) followed by ileum (7 %), cecum (3.6 %) and appendix (3 %) [1–3]. Usually, the disease takes the form of small asymptomatic serosal implants, but these can progress and become symptomatic. The symptoms are usually chronic and cyclical (occurring at the time of menses) [1–3]. Acute presentations such as intestinal obstruction, appendicitis, appendicular intussusception, rectal bleeding and bowel perforation are relatively uncommon.
