[Digestive endometriosis of the caecum and intussusception: about one case]

Ileocolonic intussusception due to severe endometriosis

Endometriosis is the presence of normal endometrial tissue outside the uterus, which may appear in up to 15% of fertile female population. Bowel endometriosis is uncommon, and obstruction due to endometrial ileocolic intussusception is extremely rare. Herein, we report a case of a 27-year-old female who presented with bowel obstruction due to ileocolic intussusception secondary to endometriosis. A 27-year-old female, without pregnancies, and with a 1 year history of endometriosis presented to the emergency department referring severe abdominal pain in right lower quadrant, nausea and vomiting, she had medical history of prior episodes of mild abdominal pain due to endometriosis with OB/GYN follow-up. Physical examination revealed abdominal distension with decreased bowel movements to auscultation. A CT scan reported suspicion of intussusception. Colonoscopy was ordered, where an ileocolic intussusception was found. Diagnostic laparoscopy was performed, and the initial diagnosis was confirmed. A right hemicolectomy with extracorporeal anastomosis was achieved without any surgical complications. The patient was discharge on postoperative day 4 and continues doing well on a 12 month follow-up. Ileocolic intussusception due to endometriosis is a very rare condition, and it must be considered a differential diagnosis in female patients in reproductive age, when presenting with intestinal obstruction.

Ileocolic intussusception due to a cecal endometriosis: case report and review of literature

Abstract

Cecal endometriosis and ileocolic intussusception due to a cecal endometriosis is extremely rare. We report a case of a woman who presented an ileocecal intussusception due to a cecal endometriosis. The patient gave two months history of chronic periombilical pain requiring regular hospital admission and analgesia. The symptoms were not related to menses. A laparotomy was performed and revealed an ileocolic intussusception. The abdominal exploration did not find any endometriosis lesion. Ileocaecal resection was performed. Microscopic examination showed a cystic component, lined by a regular cylindric epithelium. Foci of endometrial tissu were oberved in the cecal subserosa and muscularis mucosal, with irregular endometrial glands lined by cylindric epithelium without atypia immunostained with CK7, and characteristic endometrial stroma immunostained with CD10. Cecal endometriosis and ileocolic intussusception due to a cecal endometriosis is extremely rare. Diagnose of etiology remains challenging due to the absence of clinical and radiological specific characteristics.

Cecal endometriosis as a cause of ileocolic intussusception

Discussed in this report is the use of imaging modalities to aid in the preoperative diagnosis and localization of pathology in this rare condition treated with laparoscopic hemicolectomy.

Endometriosis is a disease that can affect various organs, has an unclear symptomatology, and in extreme cases, can result in intestinal obstruction. This particular case illustrates the synchronous localization of endometriosis, both genital and intestinal, resulting in ileo-colic and colonic intussusception. The relative diagnostic and therapeutic approach for such a rare occurrence is discussed.
