Hepatocellular carcinoma is a common malignancy in this locality due to the high prevalence of hepatitis B carriers. Radiofrequency ablation is frequently used for treatment of hepatocellular carcinoma. Thermal injury to the diaphragm during radiofrequency ablation for liver tumour is a rare complication. Thermal injury may lead to a defect in the diaphragm and hernia formation. Intestinal obstruction can result from incarceration of the diaphragmatic hernia. We present a patient with intestinal obstruction due to incarcerated diaphragmatic hernia after radiofrequency ablation. The causes, presentation, and imaging findings of this condition are reviewed.

右側嵌頓性膈疝：開放式射頻消融治療肝細胞癌後的一種罕見後遺症
李騰飛、朱志揚、鄭志成、邱麗珊
本港有不少乙型肝炎病毒攜帶者，這也令肝癌的發病變得普遍。射頻消融術經常用於治療肝癌。射頻消融的過程中產生的熱量導致橫隔膜損傷相當罕見。熱損傷可能會導致橫隔膜受損及膈疝的形成。而膈疝如果嵌頓後也可導致腸梗阻。本文報告一名肝癌患者在接受射頻消融術後併發嵌頓性膈疝而導致腸梗阻的病例，以此討論這種併發症的原因、表現和影像學檢查結果。
