| (Background)Endoscopic treatment of colon tumors extend into the appendiceal orifice presents significant technical challenges and raises concerns about inducing appendicitis due to treatment and suturing. Surgical intervention, such as ileo-cecal resection, can be invasive for benign tumors. Here, we report a case of RECS, that was resected a tumor extending into the appendiceal orifice. (Method)A man in his 60s with a 45mm sized cecal tumor was referred to our hospital. The tumor extended into the appendiceal orifice, and the oral side border of the lesion was unrecognizable. We diagnosed as SSL with dysplasia. After a multidisciplinary discussion, local resection using RECS was planned. (Result)First, ESD was performed to dissect the tumor in the cecum, excluding the appendiceal orifice. After the lesion was gathered nearby the appendiceal orifice, surgeons performed full thickness resection that did not involve the ileocecal valve. After surgeons sutured mucosal defect, the suture was checked endoscopically. The pathological finding was SSLD and the tumor extended into the inside of the appendiceal lumen. (Conclusion)RECS can be one treatment option for cecal tumors extend into the appendiceal orifice, offering the advantage of achieving R0 resection while minimizing invasiveness. However, challenges persist regarding an exposure of the tumor to abdominal cavity. Tumor resection may be conducted after closure with linear stapler, suggesting areas for potential refinement in the procedure. |
