Foreign body ingestion is a scenario occasionally encountered in the emergency room. Pediatric and psychiatric patients are the two most common populations suffering from accidental or in some cases intentional ingestion of foreign bodies. Commonly, majority of cases require no specific treatment and the swallowed objects pass through the digestive tract spontaneously without causing any significant complications. Less than 1% of the cases complicates with gastrointestinal tract perforation, which are often caused by sharp objects, which warrants surgical intervention. The average time from foreign body ingestion to development of perforation was noted at 10.4 days in previous reports. These cases often present in rapidly progressing peritonitis and are subsequently managed by emergent laparotomy. In this case report, we describe an accidental chopstick ingestion of a patient who initially was misdiagnosed and remained asymptomatic for nine months, then presented with acute abdomen. A 27-year-old man accidentally ingested a wooden chopstick and sought consult at a clinic. Negative abdominal plain film misled the physician to believe ingested chopstick was digested into fragments and passed out unnoticed. The patient presented acute abdomen caused by duodenal perforation nine months later and was subsequently treated with emergency laparotomy with primary duodenorrhaphy. Negative plain films are not sufficient to conclude a conservative treatment in foreign body ingestion. Computed tomography scan or endoscopic examinations should be done to rule out retained foreign body within gastrointestinal tract.

意外摄入异物九个月后十二指肠穿孔，一例报告

异物摄入是急诊室中偶尔遇到的一种情况。儿科和精神病患者是两种最常见的人群，患有意外或在某些情况下故意摄入异物。通常，大多数情况不需要特殊治疗，吞入的物体会自发通过消化道而不会引起任何严重的并发症。不到1％的病例并发胃肠道穿孔，这通常是由锋利的物体引起的，因此有必要进行手术干预。在以前的报告中，从摄入异物到出现穿孔的平均时间为10.4天。这些病例通常表现为快速发展的腹膜炎，随后通过紧急剖腹手术进行处理。在这种情况下，我们描述了误食患者的筷子，该患者最初被误诊并在9个月内无症状，然后出现了急腹症。一名27岁的男子不小心误食了一根木筷子，并在诊所寻求咨询。阴性的腹部平片误导了医生，以为吞食的筷子被消化成碎片并散发了出来而没有引起注意。该患者九个月后因十二指肠穿孔而出现急腹症，随后接受了急诊剖腹手术并伴有原发性十二指肠瘘。负性平片不足以得出保守的异物摄取治疗方法。应进行计算机断层扫描或内窥镜检查，以排除胃肠道内残留的异物。
