摘要

脂肪瘤是腸胃道少見的腫瘤，最常發生於大腸，其中以升結腸的脂肪瘤較易産生症狀，而有百分之九十的脂肪瘤位於黏膜下層。大多數的大腸脂肪瘤並不會産生症狀，通常是因爲懷疑其他大腸病變而接受檢查時之不預期發現。較常見的症狀有腹痛、排便習慣改變、腸阻塞、腹瀉、腸套疊、或腹部腫塊。在此我們報告一個六十三歲女性病忠因大腸脂肪瘤而併發腸套疊的病例，此病患因間歇性腹部絞痛三日及解血便一次而就醫。大腸鋇劑攝影顯示在橫結腸有腔內腫瘤及腸套疊，腹部電腦斷層顯示疑似大腸脂肪瘤位於腸套疊起點。最後病患接受右大腸切除術，病理檢查顯示該大腸腫瘤為由成熟脂肪細胞所組成的脂肪瘤。手術後，病患病情穩定。

Lipomas, uncommon in the GI tract, occur most often in the colon. The commonest site for symptomatic lipomas is the ascending colon. 90% of lipomas originate in the submucosa. Histologically, it is a well-differentiated tumor arising from deposites of adipose connective tissue in the bowel wall. Most colonic lipomas cause no symptoms at all. They are usually detected during the investigation of a symptom apparently derived from the large bowel. The most common manifestations are abdominal pain, change in bowel habit, obstruction, diarrhea, intussusception, or rarely a palpable mass. In this report, we describe a 63 year-old female patient with a colonic lipoma that induced intussusception. The patient had one episode of bloody diarrhea and a three-day history of severe intermittent cramping abdominal pain. Barium enema examination demonstrated an intraluminal tumor mass located in the transverse colon with colo-colonic intussusception. Abdominal CT showed colo-colonic intussusception and a suspicious colonic lipoma at leading point of the intussusception. A right hemicolectomy was performed. Microscopic examination showed a submucosal lipoma consisting of mature fit cells. After surgical treatment, the patient was discharged in stable condition.
