          Patient: Female, 34

          Final Diagnosis: Lipoma of the large intestine

          Symptoms: Abdominal pain • bloating • blood in stool • constipation • lose of appetite • nausea

          Medication: —

          Clinical Procedure: —

          Specialty: Surgery


          Rare disease


          Lipoma of the large intestine is rare, account for only 5% of all gastrointestinal tumors. Lipomas are usually asymptomatic but rarely may cause bleeding, obstruction and intussusception. We present a case of a giant colonic lipoma causing descending-colonic intussusception.

          Case Report:

          34 yo F presented with the intermittent left lower quadrant abdominal pain for 3 weeks. The pain initially was associated with bloating and constipation and for the last several days frank blood in stool, nausea and decreased appetite. CT scan of the abdomen revealed descending colonic obstruction by a 5.3 cm colonic lipomatous mass with resultant intussusception. Patient initially underwent colonoscopy that revealed polypoid lesion at 3–40 similar to lipoma with intussusception that was reduced. Patient subsequently underwent laparoscopic segmental left colectomy for the descending colonic intussusception due to large colonic lipomatous mass. Pathology confirmed the histology of lipoma.


          Adult bowel intussusception is a rare but challenging condition to diagnose in a timely manner. Preoperative diagnosis is usually missed or delayed because of nonspecific and often subacute symptoms. Lipoma is a rare cause of the intussusception. A high index of suspicion and appropriate investigations (abdominal ultrasound, CT scan and colonoscopy) can result in prompt diagnosis. Lipoma of the large intestine is very rare. Submucosal lipomas are usually asymptomatic but may cause bleeding, obstruction, intussusception, or abdominal pain. Accurate preoperative diagnosis is difficult and lipoma is often mistaken for adenomatous polyp or carcinoma. Treatment usually requires formal resection of the involved bowel segment due to high suspicion for malignancy and subsequent complications due to obstruction.

          Adult intussusception: a retrospective review of 41 cases.

          To optimize the preoperative diagnosis and surgical management of adult intussusception (AI). A retrospective review of the clinical features, diagnosis, management and pathology 41 adult patients with postoperative diagnoses of intussusception was conducted. Forty-one patients with 44 intussusceptions were operated on, 24.4% had acute symptoms, 24.4% had subacute symptoms, and 51.2% had chronic symptoms. 70.7% of the patients presented with intestinal obstruction. There were 20 enteric, 15 ileocolic, eight colocolonic and one sigmoidorectal intussusceptions. 65.9% of intussusceptions were diagnosed preoperatively using a computed tomography (CT) scan (90.5% accurate) and ultrasonography (60.0% accurate, rising to 91.7% for patients who had a palpable abdominal mass). Coloscopy located the occupying lesions of the lead point of ileocolic, colocolonic and sigmoidorectal intussusceptions. Four intussusceptions in three patients were simply reduced. Twenty-one patients underwent resection after primary reduction. There was no mortality and anastomosis leakage perioperatively. Except for one patient with multiple small bowel adenomas, which recurred 5 mo after surgery, no patients were recurrent within 6 mo. Pathologically, 54.5% of the intussusceptions had a tumor, of which 27.3% were malignant. 9.1% comprised nontumorous polyps. Four intussusceptions had a gastrojejunostomy with intestinal intubation, and four intussusceptions had no organic lesion. CT is the most effective and accurate diagnostic technique. Colonoscopy can detect most lead point lesions of non-enteric intussusceptions. Intestinal intubation should be avoided.

            Lipoma induced jejunojejunal intussusception.

            Intussusception in adults is rare. The clinical picture of intussusception in adults is subtle and the diagnosis is, therefore, elusive. The presence of a structural abnormality in the great majority of the adult cases mandates high clinical suspicion. Gastrointestinal lipomas are rare benign tumors and intussusception due to a gastrointestinal lipoma constitutes an infrequent clinical entity. The present report describes a case of jejunojejunal intussusception in an adult with a history of severe episodes of hematochezia and colicky upper abdominal pain. The diagnosis was suspected preoperatively but computed tomography scan could not rule out malignancy. Exploratory laparotomy revealed jejunojejunal intussusception secondary to a lipoma which was successfully treated with segmental intestinal resection.

              Intussusception in adults: institutional review.

              The objectives were to review adult intussusception (AI), its diagnosis and treatment. Intussusception is a different entity in adults than it is in children. AI represents 1% of all bowel obstructions, 5% of all intussusceptions. The records of all patients, 18 years and older, with the postoperative diagnosis of intussusception at the B.P.K.I.H.S during the years 2003-2009 were reviewed retrospectively. In six years, there were thirty-eight patients of surgically proven AI. The patients' mean age was 49.6 years, M:F ratio was 1.3:1. Intestinal obstructions of various extents were the commonest presentation in twenty-seven patients (71%). There were 42% enteric, 32% ileocolic and 26% colonic AI. The diagnostic accuracy of the ultrasonography was 78.5%, CT scan was 90% and colonoscopy was 100%. The pathological lesions were found in 94% of AI. Among the pathological lesion, enteric have 62% benign, 38% malignant, ileocolic have 50% benign, 50% malignant, and in colocolic 70% malignant, 30% benign. In enteric AI, 68% were reduced successfully, 25% reduction was not attempted. Of ileocolic AI, 58.3% were reduced successfully, 41.6% had resection without reduction. Of colocolic AI, 30% of them were reduced successfully before resection, 70% had resection without reduction. AI is a rare entity and requires a high index of suspicion. CT scanning proved to be the most useful diagnostic radiologic method. Colonoscopy is most accurate in ileocolic and colonic AI. The treatment of adult intussusception is surgical. Our review supports that small-bowel intussusception should be reduced before resection if the underlying etiology is suspected to be benign or if the resection required without reduction is deemed to be massive. Large bowel should generally be resected without reduction because pathology is mostly malignant. Copyright © 2010 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.
