Laparoscopic and endoscopic cooperative surgery to treat superficial neoplastic lesions involving appendiceal orifice: LECS-CR

Abstract Text Case 1: 81-year-old woman. Appendectomy. 40 mm LST-GM lesion involving appendiceal orifice. Case 2: 52-year-old man. 20 mm 0-Is lesion over invaginated appendix. Colorectal laparoscopic and endoscopic cooperative surgery procedure (LECS-CR) step by step. First, surgical release of the cecum from retroperitoneum. Target lesion is identified using colonoscope, while guiding surgeons to complete a limited cecal sleeve resection using electric endo-stappler. Last, water-tightness of the surgical suture and adequate pass to distal ileum is verified using the colonoscope. Final histology: Case 1: 40 mm tubulovillous adenoma with high-grade dysplasia, R0; Case 2: 18 mm tubulovillous adenoma with low-grade dysplasia, R0
