_Abstract

Adult intussusception is an uncommon cause of intestinal obstruction, accounting for less than 5% of cases. Unlike pediatric cases, adult intussusception is usually associated with an identifiable pathological lead point. Trans-anal protrusion of intussusception (TAPI) is exceptionally rare in adults and may mimic rectal prolapse, leading to delayed diagnosis. Inflammatory fibroid polyp (IFP) is a rare benign gastrointestinal lesion and an unusual cause of small bowel intussusception.     A 50-year-old woman presented with a cyanosed pedunculated mass protruding through the anus for three hours, along with a one-month history of hypogastric pain, nausea, vomiting, and weight loss. She had recently been diagnosed with pulmonary tuberculosis and was receiving anti-tuberculous therapy. Laboratory tests revealed leukocytosis and anemia. Ultrasonography suggested intestinal obstruction, while contrast-enhanced CT showed a target sign in the right lower abdomen consistent with ileoileal intussusception. The patient underwent urgent exploratory laparotomy with reduction of the intussusception followed by right hemicolectomy due to suspected malignancy. Histopathology confirmed a 5.7-cm inflammatory fibroid polyp of the ileum with reactive lymphadenopathy. The postoperative course was uneventful, and the patient recovered well at three-month follow-up.     Transanal protrusion of adult ileoileal intussusception secondary to inflammatory fibroid polyp is an extremely rare surgical emergency. Early recognition, appropriate imaging, and prompt surgical management are essential for favorable outcomes.
