本文总结31例胰岛细胞肿瘤的治疗经验。过细的病史、必要的化验配合、术前术中的肿瘤定位及全面细致的术中手法探查是手术成功的关键。无功能性胰岛细胞瘤早期诊断较难,B超与CT是诊断的主要手段。它多数位于胰头,是低度恶性肿瘤,应扩大手术范围及长期随访。术中未能找到肿瘤者可作术中胰静脉血IRI测定或门静脉分段采血测定IRI及术中应用B超定位。除非证实为弥漫性胰岛增生者,尽量少作盲目性胰切除术。
This article summarizes the treatment experience of 31 cases of pancreatic islet cell tumors. The history of surgery, the necessary laboratory tests, the positioning of the tumor in the preoperative operation, and comprehensive and detailed intraoperative exploration are the keys to successful operation. The early diagnosis of nonfunctioning islet cell tumors is difficult. B-ultrasonography and CT are the main methods for diagnosis. Most of it is located in the head of the pancreas. It is a low-grade malignancy and should be expanded in scope and long-term follow-up. Those who could not find the tumor during the operation could use IRI for intraoperative pancreatic venous blood or IRI for portal vein blood sampling and B-ultrasound during operation. Unless it is confirmed as diffuse islet hyperplasia, as little as possible blind pancreatic resection.
