  • adult Intussusception caused by cystic lymphangioma of the Colon a rare case report
    World Journal of Gastroenterology, 2006
    Co-Authors: Tae Oh Kim, Junghyun Lee, Gwang Ha Kim, Jeong Heo, Dae Hwan Kang, Geun Am Song, Mong Cho
    Abstract:

    We experienced a case of Intussusception caused by cystic lymphangioma of the Colon in a 32 years old female who was admitted to our hospital for the chief complaint of bloody stool. In the Colonoscopic examination, cystic mass with stalk which had smooth mucosal surface was noted at the descending Colon. Abdominal ultrasonography and computed tomography revealed left Colon Intussusception with a multilocular cystic tumor as a leading point. Emergent operation was performed. On the histopathologic examination, the cystically dilated spaces lined by endothelium and septated by fibrous septa were present. The pathological diagnosis was cystic lymphangioma of the Colon. Although Intussusception due to lymphangioma in an adult are rare, it should be taken into consideration that it is possible diagnosis.

  • tu1756 laparoscopic treatment of a giant Colonic lipoma presenting as transverse Colon Intussusception and lower intestinal bleeding a case report
    Gastroenterology, 2015
    Co-Authors: Beatriz De Rienzo, Horacio Montanezramirez, Fernando Quijanoorvananos
    Abstract:

    Introduction: Intussusception in adults accounts for 5% of bowel Intussusceptions and of 1% of bowel obstructions. Most adult Intussusceptions have a demonstrable lead point. Colonic lipomas are a rare cause of Intussusception. They are usually small and asymptomatic, with only 30% reaching more than 2 cm at which point they develop symptoms which include anemia, abdominal pain, constipation, diarrhea, bleeding and Intussusception. Giant lipoma has been defined as >5 cm in diameter. We present a case of a 6 cm lipoma in the transverse Colon causing gastrointestinal bleeding and colo-Colonic Intussusception. Case: A 31 year-old male patient presented to the emergency room with a one month history of melena and hematochezia, colicky abdominal pain and in the previous 24 hours nausea, vomiting and abdominal distention. Contrast-enhanced CT scan showed a colo-Colonic invagination of transverse Colon telescoping into the descending Colon (Fig. 1). An enema with hidrosoluble contrast was performed with resolution of the Intussusception, and an intraluminal oval pediculated mass of 65x41x37 mm with a density of -21 HU was observed at the splenic angle. Colonoscopy reported a submucosal mass with a blood clot causing obstruction of the bowel lumen 55 cm from the anal verge; its proximal and distal margins were marked with blue dye. The patient was taken to surgery and a laparoscopic segmental transverse colectomy was performed. The histopathological report revealed a 6x5x4 cm submucosal lipoma (Fig. 2). The postoperative evolution was uneventful and the patient was discharged on the fifth postoperative day. Discussion: Colonic lipomas are benign nonepithelial tumors which present most commonly in females within the fifth and sixth decades of life. They are most commonly located in the ascending Colon (61%), followed by the descending Colon (20%), transverse Colon (15%) and rectum (3.4%). Symptoms appear in lipomas >2 cm: anemia, colicky abdominal pain, constipation, bleeding and Intussusception. Diagnostic methods include CT scan, contrast-enhanced enema, and Colonoscopy. CT scan will reveal a regular, well-delimited spherical or ovoid mass of adipose density (-40 to -120 HU). If associated with Intussusception it will show a target lesion, a sausage-shaped mass with layers or a mass caused by edema, mural thickening and vascular compromise. Contrast enhanced enema may aid in the reduction of an Intussusception and additionally demonstrate a filling defect. Colonoscopy will reveal a submucosal lesion with three characteristic signs: "cushion sign," "tenting effect," and "naked fat sign." Treatment for symptomatic lipomas includes endoscopic excision or surgical resection, with size being the delimiting factor. Segmental colectomy is the gold standard and may be performed laparoscopically.

  • giant Colonic lipoma arising from the ileocecal valve and causing cecal transverse Colonic Intussusception
    Advances in Digestive Medicine, 2016
    Co-Authors: Rongnan Chien, Chihlang Lin, Chingjung Liu
    Abstract:

    Summary Intussusception is rare in adults, representing only 1% of bowel obstruction and 5% of all Intussusceptions. Previous reports have shown that > 90% of adults diagnosed with Intussusception had an identifiable pathological leading point—a malignant tumor in 43–63% of the cases. Colonic lipomas are rare nonepithelial neoplasms, but represent the most common benign tumors in the large intestine. Most Colonic lipomas present as submucosal, sessile polypoid masses with intact mucosa, and they rarely produce symptoms when 4 cm in diameter. As the clinical presentations of adult Intussusception are not pathognomonic and the image study may not provide a typical presentation, a precise preoperative diagnosis of whether a benign or malignant tumor is causing the Colon Intussusception can be difficult. Here, we report the case of a 50-year-old man who presented with abdominal pain and lower gastrointestinal bleeding and was diagnosed postoperatively with ileocecal valve lipoma with cecal-transverse Colon Intussusception. This report emphasizes Colonic lipomas > 4 cm in diameter should receive surgical resection before Intussusception develops. However, if the nature of the tumor causing Colon Intussusception cannot be identified before the operation, en bloc resection is recommended as there is a high risk of malignancy spreading.
