A 73-year-old male with a history of surgery for advanced gastric cancer underwent routine follow-up ２ years and ６ months postoperatively, during which a fecal occult blood test was positive. Colonoscopy revealed a submucosal tumor-like lesion in the transverse colon, which was diagnosed as recurrent gastric cancer with colonic metastasis. The lesion progressively enlarged and caused colonic obstruction, prompting placement of a self-expandable metallic stent. The patient subsequently received chemotherapy and was later transitioned to palliative care. No recurrent colonic obstruction developed, and the patient died from disease progression １ year and ２ months after stent placement. Colonic metastasis from gastric cancer is a rare form of distant metastasis and is generally associated with a poor prognosis. When obstruction occurs, palliative decompression is essential. To date, no reports have described colonic stent placement for colonic stenosis caused by metastatic gastric cancer. In patients with limited life expectancy, colonic stenting may provide a minimally invasive option for symptom relief.
