摘要
目的:探讨胰腺良性肿瘤定位方法与术式选择。方法:对手术治疗的12例病例进行分析。结果:全组术前B超、CT阳性率分别为50%(6/12)、67%(8/12);其中胰岛β细胞瘤分别是14%(1/7)、43%(3/7),术中B超阳性率75%(3/4),而选择性动脉造影(SAG)阳性率是100%(4/4);胰腺囊腺瘤和胃泌素瘤术前B超、CT阳性率均是100%(5/5)。行瘤体剜除术4例,胰体尾切除术5例,胰头十二指肠切除术2例和胰腺契形切除术1例。结论:B超、CT是胰腺良性肿瘤较为实用的术前定位方法;SAG是胰岛β细胞瘤B超阴性患者的首选;术中B超对胰腺实质内微小肿瘤的定位很有价值。准确的定位诊断是胰腺良性肿瘤术式选择及手术成功的关键。
Objective:Studying the methods of localization of pancreatic benign tumour and selecting the surgical procedures.Methods:Analyzing the 12 case of patients who were treated surgically.Results The positive rates of the tumour with preoperative ultrasonography,computed tomography were 50%(6/12)、67(8/12)and among that,insulinomas were 14%(1/7)、43(3/7)respectively.The intraoperative sensitivity of ultrasonography was 75%(3/4),and that of selective arteriography sensitivity of ultra-sonography was 75(3/4),and that of selective arteriography was 100%(4/4).The preoperative sensi-tivities of pancreatic cystadenoma and gastrinoma were all 100%(5/5).Among our patients the following surgieal procedures were performed:enucleation of the tumour in 4,distal panereatectomy in 5,Whipple procedure in 2,and cuniform resection in 1.Conclusion:Ultrasonography and computed tomography were relatively useful localization methods for pancreatic benign tumour,and selective arteriography was the first choice for insulinomas which ultrasonography was negative;intraopertive ultrasonography was a valuable method for detectíng the small sites in pancreatic parenchyma.Accurate localization of pancreatic benign tumour was the key step for choosing the surgical procedures and performing the operation suc-cessfully.
