Colonic Intussusception occurs more frequently in pediatric age and most often it is idiopathic. In contrast intussusception in adults is rare and accounts to less than 16% of cases [1],[2] . In adults the underlying etiology has been identified in more than 80% of cases, where malignant and benign neoplasm account to 75% [3] . Colonic lipomas may induce intussusception. They are rare, usually small and allocated to the right colon. Larger pedunculated lipomas have been associated with intermittent colonic Intussusception [4].

We report a case intussusception in a young woman induced by a large sigmoid lipoma, which was managed successfully by endoscopic reduction and removal of the lipoma.

   Case Report Top

A 35-years old female, para 6+0, 20 days post normal spontaneous vaginal delivery, who underwent cesarean section three years prior to her admission presented to the emergency department, King Khalid University Hospital, Riyadh with intermittent, colicky left sided abdominal pain of two weeks duration. The pain was associated with occasional nausea, vomiting and loose motion with hematochezia.

Abdominal examination revealed a scar of previous cesarean section. The abdomen was soft and lax. A lOx4cm large, sausage-shaped tender mass was palpated at the left iliac fossa. On digital examination the rectum was empty, no blood or mucus noted. General and systematic examination was unremarkable.

Hematological and biochemical investigations were normal. Erect and supine abdominal radiography showed features of large bowel obstruction. A limited gastrographin enema revealed a well-defined mass occluding the bowel lumen at the mid sigmoid colon highly suggestive of intussusception induced by a colonic polyp [Figure - 1]. Also, abdominal ultrasonography supported the diagnosis and demonstrated a homogenous, oval, well-defined, 5cm large mass within the sigmoid colon along with proximal features of a linear mass [Figure - 2].

Urgent colonoscopy showed a large, oval, polypoid mass with a smooth surface and shiny mucosa at 30 cm above the anal verge obstructing the lumen and forming the lead point of intussusception. A successful endoscopic reduction and removal of the mass using a large polyrectomy. snare was achieved [Figure - 3].

The gross pathological examination revealed a 7.5x4.5cm, large Lipoma with ulcerated hemorrhagic surface. The histopathological section showed lobules of mature lipocytes separated by thin fibrovascular connective tissue septa [Figure - 4]. The post endoscopic treatment period was uneventful. The patient was discharged on the third day after she tolerated normal diet and opened her bowel normally. Barium double contrast and colonoscopy performed two months later were normal. The patient visited regularly the outpatient clinic for one year and she remained asymptomatic over the whole period.

   Discussion Top

Colonic limpoma are rare with a reported autopsy incidence of 0.2% [5] . They are commonly located at the right colon in particular the ceum[4] . Majority occurs in elderly [3] and usually does not produce symptoms unless they exceed 4 diameter [5]. Our patient presented with intermittent colicky, abdominal pain, vomiting, loose motion and hematocheazia due to sigmoid intussusception induced by a large Limpoma. Intussusception in adults has been in the majority of cases due to malignant or benign neoplasm [3] . Limpomas are known to induce intussusception [4],[6],[7],[8],[9],[10] . Imaging techniques have been utilized to diagnose intussusception. While plain abdominal radiography has been non-specific, barium enema has diagnosed intussusception, mass or obstruction in 95% of cases [3] nowadays abdominal ultrasonography and computed tomgraphy have been more commonly utilized for a definitive diagnosis of intussusception. Abdominal ultrasonography reveals a target-like appearance in a cross-section and parallel hypoechoic alternating with hyperchoic lines in the longitudinal axis [8],[11] . Computed tomgraphy reveals thickening of the wall with a mass with fat density [12] . Alteration of fat density may occur as a result of fat necrosis due to intussusception [13] . In our patient and the plain film demonstrated evidence of large bowel obstruction. Water soluble contrast and abdominal ultrasonography were diagnostic for intussusception. Computed tomgraphy was not performed. In a series, primary colonic cancer has contributed to two thirds of colonic intussusception in adults. Therefore, hemicolectomy without reduction has been advocated. In contrast careful endoscopic search for cancer in patients with sigmoidorectal cancer is mandatory [3] . Recently, laparoscopic hemicolectomy has been recommended for intussusception caused by benign colorectal pathology such as lipoma[14].

Our patient was prepared for emergency surgical management immediately after endoscopic evaluation. During endoscopy an agreement between the educated patient, her brother, a consultant pediatrician, the surgeon and the gastroenterologist was made to remove the polypoid mass endoscopically taking the risk of perforation and bleeding in consideration.

The post endoscopic treatment was uneventful. We are not aware of endoscopic removal of Lipoma inducing intussusception. Although, it is not a standard management, hemicolectomy was avoided in this young patient.
