摘要
目的总结胰岛素瘤的诊断方法和外科治疗效果。方法回顾性分析近26年来收治的胰岛素瘤137例患者的临床资料。结果男77例,女60例。137例均具有典型的Whipple三联症。B超,CT,MRI检查的阳性率分别为35.1%,67.9%,58.1%。126例手术治疗患者中,102例(80.9%)行胰岛素瘤摘除术,4例(3.2%)行胰十二指肠切除术,16例(12.7%)行胰体尾切除术,另外4例(3.2%)行开腹探查术。切除的122例肿瘤中,良性占96.7%,恶性3.3%;单发肿瘤98.4%,多发1.6%。86.9%肿瘤直径≤2.0cm。13.1%肿瘤位于胰头;位于胰体和胰尾者分别为46.7%和40.2%。结论Whipple三联症,结合IRI,IGR,C-肽,以及胰岛素原的检测水平,可作为胰岛素瘤的定性诊断依据。胰岛素瘤的定位诊断仍很困难,联合应用多种影像学检查方法有助于提高检出率。治疗首选肿瘤摘除术,如果术中探查未能找到肿瘤,不宜盲目行胰体尾切除术,应排除其他原因所致低血糖症,同时进一步完善影像学检查方法,明确定位后,再考虑二次手术治疗。
Objective To summarize the methods of diagnosis and results of surgical treatment of pancreatic insulinoma. Methods The clinical data of 137 patients with insulinoma treated in our hospital during the past twenty-six years were reviewed retrospectively. Results There were 77 males and 60 females. All of them were characterized by the Whipple＇ s triad. The sensitivity of uhrasonography, CT and MRI for localization was 35. 1% , 67. 9 % and 58. 1% respectively. One hundred and tweenty-six patients underwent operation. Of them, 102 cases had tumor enucleation, 4 cases had pancreaticoduodenectomy, 16 cases had distal panreatectomy, and the other 4 cases had only laparotomy. Of the 122 patients, who underwent resection, the tumor was benign in 118 （ 96.7 % ） and malignant in 4 （ 3.3 % ）. The diameter of the tumor was less than 2 cm in 86. 9 % of cases. In 98.4 % of cases the tumors were single and in 1.6% of cases were multiple. 13. 1% of the tumors located in the head, 46. 7 % in the body, and 40.2% in the tail. Conclusions Whipple＇s triad and the measurement of fasting glucose, IRI, IGR, C-peptide, and proinsulin levels contribute to the diagnosis of insulinoma. However, the preoperative tumor localization is still difficult. Tumor enucleation is the technique of choice when feasible. Patients in whom tumor localization is unsuccessful at operation should be carefully evaluated to be certain of the diagnosis, and in general should not undergo blind resection.
