Malignant bowel obstruction often causes oral intake difficulties and decreases quality of life. In Japan, gastroduodenal stenting for malignant gastric outlet obstruction has been covered by health insurance since 2010, while colon stenting has been covered since 2012. Both approaches are useful treatments for malignant bowel obstruction. Here we report the case of a woman with gastric outlet obstruction and rectal obstruction due to breast cancer metastases who was able to eat solid food after duodenal and colon stenting. When choosing whether to perform endoscopic stenting or surgical intervention such as gastrojejunostomy, ileostomy, and colostomy for treating malignant bowel obstruction, it is important to assess the patient's general condition and prognosis as well as the obstruction position.
