INTRODUCTION
Lead colic is a rare cause of abdominal pain. The diagnosis of lead poisoning is most often mentioned in at risk populations (children, psychotic patients).
CASE REPORT
We report a 21-year-old man who presented with colicky abdominal pain. Abdominal plain radiograph showed multiple intracolonic metallic bodies. Markedly elevated lead and zinc protoporphyrin serum levels confirmed the diagnosis of lead poisoning. The patient reported that he commonly chewed fishing lead sinker and may sometimes swallow them during the preparation of fishing rod. Clinical outcome was favourable with chelation therapy.
CONCLUSION
Lead poisoning following fishing sinker ingestion is very uncommon. Diagnosis may be discussed in the presence of foreign metallic bodies on plain abdominal radiograph and confirmed by high serum level of lead. A prompt treatment with chelation therapy and digestive emptying is usually effective.
引言
铅绞痛是腹痛的罕见原因。铅中毒的诊断最常出现在高危人群（儿童、精神病患者）中。
病例报告
我们报告一名21岁男性，他出现绞痛性腹痛。腹部平片显示结肠内有多个金属物体。血清铅和锌原卟啉水平显著升高，证实了铅中毒的诊断。患者报告说，他经常咀嚼钓鱼铅坠，在准备鱼竿时有时可能会吞下它们。螯合疗法的临床效果良好。
结论
摄入钓鱼铅坠后发生铅中毒非常罕见。在腹部平片上发现外来金属物体时可考虑诊断，并通过高血清铅水平得以证实。螯合疗法和消化道排空的及时治疗通常是有效的。
