IntroductionIntussusception is defined as the invagination of one segment of the gastrointestinal tract and its mesentery (intussusceptum) into the lumen of an adjacent distal segment (intussuscipiens). Intussusception is the most common cause of acute small bowel obstruction in children aged less than three years but comprises only 1-5% of adult bowel obstruction presentations. Additionally, in the adult population, a pathological lead point is often identifiable, whereas a minority of pediatric intussusceptions present with a lead point. Of the 5% adult intussusception, malignancy forms the majority of lead point etiology (65%–70%).1 A lipoma is a rare cause of adult intussusception but has been documented in cases worldwide.2 This report describes a case of a late presentation of an adult intussusception due to a lipoma with classical imaging findings and intraoperative photographs of the lesion. The role of bowel resection in patients with large submucosal lipomas should be considered to prevent future complications.

IntroductionBicycle handle bar injury occurs when the handlebar of the bicycle strikes to cause an impact on the body. This mechanism of injury is responsible for a significant number of thoraco-abdominal injuries in children with more than a third of them requiring surgical intervention.1 The most common among them involves intra-abdominal organ injuries,  traumatic abdominal wall hernias and bladder rupture.2–4 However, retroperitoneal hematoma has rarely been reported in bicycle handle bar injury.5 Bleeding into the space behind the peritoneal cavity, referred to as retroperitoneal hematoma, is an obscure and under diagnosed condition due to the late manifestation of signs and symptoms until significant blood loss has occurred.6 Here, we present a case of 12 years old boy brought to the emergency department with the alleged history of bicycle handle bar injury who underwent emergency exploratory laparotomy that revealed massive retroperitoneal hematoma secondary to mesenteric/ vascular injury with intra-peritoneal extent.
