Abstract
BACKGROUND
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).
CASE SUMMARY
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.
CONCLUSION
Ileocecal LSTs with appendiceal tubular adenomas are traditionally treated with LA. endoscopic submucosal dissection can also yield favorable outcomes.
Core Tip: Ileocecal laterally spreading tumors with appendiceal tubular adenoma are rare and hard to diagnose due to nonspecific symptoms. Traditionally treated by laparoscopic appendectomy, new research shows endoscopic submucosal dissection can be effective. This case innovatively applied sequential endoscopic submucosal dissection for high-grade dysplastic lesions at the appendiceal orifice, followed by appendectomy preserving the ileocecal valve. This approach improved postoperative quality of life and presents a novel strategy for deep-seated appendiceal lesions, addressing visualization challenges in deep lumen extension.
