Ileocecal laterally spreading tumors (LSTs) complicated by appendiceal tubular adenoma are rare and challenging to diagnose because of the absence of typical symptoms and specific diagnostic signs. Traditionally, the primary treatment has been laparoscopic appendectomy (LA).
A 63-year-old female presented with changes in bowel habits. Colonoscopy revealed an ileocecal LST. The patient underwent endoscopic submucosal dissection. Postoperative follow-up colonoscopy revealed mucosal elevation at the appendiceal orifice, with pathology confirming tubular adenoma. Abdominal computed tomography indicated a suspicious appendiceal tumor, leading to LA with partial cecectomy. The postoperative recovery was uneventful. At the 1-year follow-up, colonoscopy revealed no evidence of tumor recurrence.
Ileocecal LSTs with appendiceal tubular adenomas are traditionally treated with LA. endoscopic submucosal dissection can also yield favorable outcomes.
回盲部侧向发育型肿瘤（LSTs）合并阑尾管状腺瘤较为罕见，由于缺乏典型症状和特异性诊断体征，诊断具有挑战性。传统上，主要治疗方法是腹腔镜阑尾切除术（LA）。
一名63岁女性出现排便习惯改变。结肠镜检查发现回盲部LST。患者接受了内镜下黏膜下剥离术。术后随访结肠镜检查发现阑尾开口处黏膜隆起，病理证实为管状腺瘤。腹部计算机断层扫描显示阑尾肿瘤可疑，遂行LA加部分盲肠切除术。术后恢复顺利。在1年随访时，结肠镜检查未发现肿瘤复发迹象。
传统上，回盲部LSTs合并阑尾管状腺瘤采用LA治疗。内镜下黏膜下剥离术也可取得良好效果。
