A laparoscopic odyssey: Managing giant colonic lipoma-induced colo-colonic intussusception - A case report

Introduction: Colonic lipomas (CL) are rare non -epithelial benign tumors. Giant Colonic lipomas ( >4 cm) can cause serious complications such as bowel obstruction, massive bleeding, perforation, and intussusception. Early diagnosis is difficult and preoperative discrimination between malignant lesions and large cl is challenging. Surgical resection is the cornerstone of the treatment. Case presentation: A 57 -year -old woman presented to our surgical department complaining about intermittent crampy abdominal pain with an alternation of diarrhea and constipation for the last 7 months. After radiological and endoscopic investigations, the diagnosis of colo-colonic intussusception caused by colonic lipoma was confirmed. The patient underwent laparoscopic enucleation and a histopathological examination of the specimen confirmed the diagnosis of colonic lipoma. Discussion: Colonic lipomas (CL), though rare (0.2 to 4 %), are the third most common benign colon tumors. Typically affecting adult women (57 %), these non -epithelial growths can vary in size from 2 mm to 30 cm, often remaining asymptomatic until complications arise. Colonic lipomas may lead to intussusception or bowel obstruction, with clinical presentation depending on size and location. Diagnosis relies on abdominal CT scans or MRI, while treatment options include surveillance, endoscopic, or surgical resection. Laparoscopic approaches offer favorable postoperative outcomes, although precise localization remains a challenge. Endoscopic techniques are limited, particularly for larger or difficult -to -access lipomas, necessitating expert care. Conclusion: Giant colonic lipoma can cause colonic intussusception leading to emergency operation. We think that laparoscopic enucleation seems to be the ideal treatment choice, especially when the malignancy cannot be excluded.
