Adult colorectal intussusception caused by giant lipoma-A case report.
Clinical Case Reports 2024 April
KEY CLINICAL MESSAGE: Adult intussusception commonly has a leading point. In the colon, malignancy is a prevalent etiology for the leading point; however, benign tumors should also be considered. We present a case of colorectal intussusception caused by a giant lipoma.
ABSTRACT: Intussusception in adults is comparatively infrequent in contrast to children, and in adult colonic intussusception, malignancy is the predominant cause of the leading point. Lipoma, an uncommon tumor in the gastrointestinal tract, rarely induces colonic intussusception in adults. We present the case of a 55-year-old Cambodian man experiencing cramping abdominal pain. He presented with mild abdominal distension with tenderness in the lower abdomen. On the rectal examination a large palpable mass was detected three to four centimeters from the anal verge. Abdominal computerized tomography revealed a collapsed sigmoid colon with mesenteric fat invaginated into the lumen of the upper rectum. Emergency laparotomy was performed and during the surgery the sigmoid intussusception spontaneously reduced. A mass was identified in the mid-sigmoid colon, leading to the decision for segmental resection of the sigmoid colon with the mass and subsequent end-to-end anastomosis. Histological examination results confirmed the mass as a lipoma. Colorectal intussusception in adults due to a lipoma is a relatively rare, with only a few reported cases in the literature.
