Intestinal Lipomas Inducing Intussuception: Report of 3 Cases

腸道脂肪瘤是不常見的良性瘤。其發生率臨床報告約在0.003至0.83%，而解剖報告則可高達5.8%之好發率。女性約為男性之1.5倍，多發生於50歲至70歲之年齡層，脂肪瘤真正發生之原因尚不清楚。小的腸道脂肪瘤多數無症狀，常在例行大腸鏡檢查時被檢出，腫瘤直徑大於2公分以卜則常有間歇性腹痛、便秘、腹瀉或血便，少部份病人則可發生腸套疊或腸阻塞。胃腸道脂肪瘤以長在大腸者居多（約65~75%）其次為小腸（佔20~25%）小部份長在胃或食道（小於5%）；長在大腸之脂肪瘤則好發於盲腸及升結腸，再則是乙狀結腸，長於左降結腸的較罕見，以Submucosal type佔約90%。本報告提出3例，1男2女，年齡為66、70及82歲，其中1例之脂肪瘤長在迴腸，另外2例之脂肪瘤則長在降結腸靠近脾彎曲部位。三例均接受全身麻醉下之傳統開腹手術，作腫瘤節段局部切除。手術後病人均順利康復。

Intussusception of the intestine usually occurs in infants and children. In adults an intussusception seldom occurs and is mainly caused by polyps or other intraluminal lesions, one of which is the gastrointestinal lipoma. Intestinal lipomas have been detected throughout the gastrointestinal tract from the hypopharynx to the rectum, but the most common site is the cecum. After adenomas, they are the most common benign tumors of the colon. Small lipomas of the intestine are asymptomatic and require no treatment. Tumors larger than 2 cm in diameter may cause symptoms such as intermittent abdominal pain, constipation, diarrhea, and/or rectal bleeding. Incidentally, lipomas may lead to intestinal obstruction or intussusception. A laparotomy will be necessary in such circumstances. We herein report 3 cases of intestinal lipomas with intussuception, 1 male and 2 females, aged 66, 70 and 82 years-old, respectively. One patient had the lipoma located at the ileum and the other 2 patients had them located at the descending colon near the splenic flexure. They all received laparotomy with tumor resection, with good surgical outcomes.
