Abstract

Introduction: Lipomas are the second most common benign tumors of the colon after adenomatous polyps. Their incidence is less than 1% in general population. They are generally located in the submucosa and their distribution tends to favor the right colon. Most cases are asymptomatic and do not require any special treatment. Lipomas larger than 2 cm tend to be symptomatic and are mistaken for cancer.

Clinical series: Sixteen patients of colonic submucosal lipomas operated between 2000 and 2013 were analyzed as regards of age, gender, clinical symptoms, tumor localization, diagnostic tools, size of tumor, complications and treatment modalities.
Six patients were women. The mean age was 51 years (range 35-86). The size of the tumors were measured between 0.8-6 cm. Four patients required urgent abdominal exploration and twelve patients underwent elective surgery with the diagnosis of colonic tumoral lesion. The reason for urgent exploration was colonic obstruction as a result of intussusception caused by colonic lipomas. In two patients, colonic lipomas were diagnosed coincidentally with a colonic carcinoma and a colonic diverticulosis. Surgical pathologic examination confirmed colonic lipomas in all cases. There was no mortality. During postoperative follow-up period, the patients were free of symptoms and there was no recurrence.

Conclusion: Colonic lipoma although rare, should be kept in mind while evaluating the adult patient with colonic submucosal tumor or with colonic intussusceptions to avoid unnecessary wide resections.
