Clinical Analysis on Endoscopic and Surgical Treatment Outcome of Colonic Lipomas: A 12-year Study in Southern Taiwan

Abstract

Background. Colonic lipomas are relatively uncommon tumors.We aimed to analyze the clinical outcome of colonic lipomas and discuss the controversial issues on surgery or endoscopic treatments. Methods. Over 12 years period, six-teen confirmed diagnoses of colonic lipomas were enrolled. They were analyzed by dividing into surgical (n=9) and endoscopic treated group (n=7). Diagnosis of colonic lipoma was made based on pathological report. Results. More symptomatic patients were observed in the surgical group (p=0.001). Patients in the endoscopic treated group had smaller size lipoma than the surgical group (median (interquartile range, IQR) size of 0.9 (0.6-3.5) cm vs. 3.3 (2.75-4.1) cm, p=0.016). Six patients received laparoscopic surgery and three of them by single-incision laparoscopic surgery. There were no immediate procedure-related morbidity and mortality in current study. Conclusions. Treatment outcome of colonic lipomas are good for both surgical resection and endoscopic treatments with appropriate decisions. Generally, larger colon lipomas without stalk should be treated by surgical resection, especially the sessile or broadly-based ones, malignant appearance on endoscope examination, and in symptomatic patients like intussusception or severe bleeding.
