Colonic lipomas are rare, benign neoplasms, typically asymptomatic, and predominantly found incidentally during autopsy or routine surveillance. Symptomatic lesions are usually those greater than 2 cm in diameter while "giant" lesions are characterized as those over 4 cm. Presentations can vary from asymptomatic to more severe sequelae, including obstruction, gastrointestinal bleeding, or intussusception. Resection of these lesions has historically been restricted to large or symptomatic lesions. However, recent reports suggest lipomas may retain the ability to grow and can become symptomatic over time despite being inconsequential initially. This series provides a review of the clinical manifestations of colonic lipomas, radiographic characteristics, and a treatment recommendation for management of these lesions using minimally invasive surgical techniques whilst advocating for consideration of resection prior to the development of symptoms or more emergent complications.
结肠脂肪瘤是罕见的良性肿瘤，通常无症状，主要在尸检或常规检查时偶然发现。有症状的病变通常是直径大于2厘米的，而“巨大”病变则指直径超过4厘米的。临床表现从无症状到更严重的后遗症不等，包括梗阻、胃肠道出血或肠套叠。过去，这些病变的切除仅限于较大或有症状的病变。然而，最近的报告表明，脂肪瘤可能具有持续生长的能力，并且随着时间的推移可能会出现症状，尽管最初并不严重。本系列文章综述了结肠脂肪瘤的临床表现、影像学特征，并就使用微创外科技术治疗这些病变提出了治疗建议，同时主张在出现症状或更紧急的并发症之前考虑进行切除。
