title: [A Case of Malignant Obstruction of the Colon Due to Peritoneal Dissemination of Gastric Carcinoma Treated with Colon Stenting and Colectomy after Chemotherapy].
abstract: A man in his 60s underwent gastrectomy to treat gastric carcinoma. Approximately 2.5 years after the surgery, he was admitted to the hospital because of abdominal pain. He was diagnosed with obstruction of the transverse colon due to a colon tumor. A stent was placed to treat the obstruction and avoid oncologic emergency. Biopsy results and imaging showed that the patient did not have colon cancer, but his previous gastric cancer had disseminated peritoneally. Chemotherapy was selected as treatment for recurrent gastric cancer. After chemotherapy, the patient underwent colectomy with removal of the stent. His postoperative course was good, and he was discharged from hospital without complications. The patient received additional chemotherapy. We encountered a case of colon obstruction due to peritoneal dissemination of gastric cancer that was successfully treated using a metallic colorectal stent. Colon stenting for malignant bowel obstruction is useful to avoid oncologic emergencies. However, there is no evidence at this time that long-term placement of a stent is safe. The decision to remove or retain the stent should be made upon carefully considering the condition of the patient and progression of the disease.
