Mochi, or rice cake, is a highly adhesive food, and it is known to cause small bowel obstruction and gastric ulcers. However, reports of duodenal involvement due to mochi are rare. We report a case of duodenal obstruction and ulcers caused by mochi. A 64-year-old man with a history of diabetes mellitus presented with abdominal pain and vomiting after consuming mochi. Computed tomography (CT) of the abdomen revealed multiple high-density materials in the duodenum and stomach. Endoscopy identified multiple ulcers in the duodenum and stomach, along with mochi impaction in the duodenum. The obstruction was successfully relieved by endoscopic fragmentation. In patients with diabetes mellitus, impaired gastrointestinal motility may contribute to duodenal obstruction by mochi. When high-intensity material is observed in the stomach or duodenum on CT, confirming dietary intake is crucial for an accurate diagnosis.
年糕，又称米糕，是一种粘性很强的食物，已知会导致小肠梗阻和胃溃疡。然而，因年糕导致十二指肠受累的报道很少。我们报告一例由年糕引起的十二指肠梗阻和溃疡病例。一名有糖尿病史的64岁男性在食用年糕后出现腹痛和呕吐。腹部计算机断层扫描（CT）显示十二指肠和胃内有多个高密度物质。内镜检查发现十二指肠和胃内有多处溃疡，同时十二指肠内有年糕嵌塞。通过内镜破碎成功解除了梗阻。在糖尿病患者中，胃肠动力受损可能导致年糕引起十二指肠梗阻。当CT上在胃或十二指肠中观察到高密度物质时，确认饮食摄入情况对于准确诊断至关重要。
