Multiple von Meyenburg complexes mimicking diffuse liver metastases from esophageal squamous cell carcinoma

Von Meyenburg complexes are benign liver lesions consisting of adenomatous bile duct proliferates. We present two patients suffering from esophageal cancer accompanied by the occurrence of yon Meyenburg complexes. Preoperative computerized tomography （CT） of the liver had not shown these lesions. In one of the patients, diffuse nodular manifestation was found in both liver lobes, mimicking diffuse hepatic metastases. Intraoperative frozen section revealed the benign nature of the lesions in both cases. The patients underwent esophageal resection without complications. To the best of our knowledge, the coincidence of von Meyenburg complexes and esophageal cancer has never been reported before. This uncommon entity should be taken into consideration as a differential diagnosis of liver lesions in malignancies. It underlines the importance of intraoperative frozen section for liver lesions of unknown origin.

全胰切除术在原发性胰腺肿瘤治疗中的价值——一个重新被认识的少见术式

目的本文探讨全胰切除术后患者围手术期并发症和长期生存预后。背景胰腺切除术是胰腺癌综合治疗中的重要方法之一,也是唯一可能治愈胰腺癌的方式。目前,胰十二指肠切除术和胰体尾部切除术已成为固定术式,其近期及远期效果得到临床证实。然而,有关全胰切除术在胰腺肿瘤治疗中的价值的研究较少。方法收集2001年10月至2012年9月期间德国海德堡大学医学院行全胰切除术的596患者资料,排除不符合纳入标准的152例,共纳入434例患者：63例术前发现肿瘤位于胰腺中段或胰腺多发性病灶;126例术中探查发现肿瘤巨大而更改手术方案;156例胰腺切缘术中冰冻提示肿瘤残留而行全胰切除术;40例患者行肝动脉、腹腔干、肠系膜上动脉切除或重建;4例因胰腺部分切除术后残留部分胰腺组织病变。
