Laparoscopic treatment of intussusception in giant submucosal lipoma sigma
Colonic lipomas have very low frequency, are usually asymptomatic and diagnosis is made incidentally. Seventy-five per cent of lipomas larger than 4 cm are symptomatic, causing abdominal pain, rectal bleeding, obstruction and exceptionally invagination. The resection of invaginated segment is mandatory in cases with invagination and can be performed by laparoscopy when colonic dilation is moderate. We present a 73-year-old man who entered the emergency department complaining of intermitent abdominal pain, rectal bleeding, absence of bowel movements and flatulence, during four days. A CT scan showed a generalized colonic dilation until left lower quadrant. A colo-colonic invagination secondary to an endoluminal lipoma was observed in sigmoid colon. A laparoscopic sigmoidectomy was performed with extracorporeal termino-terminal anastomosis. The postoperative period was uneventful and the patient was discharged from the hospital five days later. A sumbmucous colonic lipoma was diagnosed in the pathological study.
