本院1992年1月～1995年12月经手术病理证实6例胰岛素瘤患者,其中男性4例,女性2例,年龄从16～63岁。6例患者均以发作性意识障碍、反复晕厥或抽搐昏迷、出汗心慌等为主诉。术前空腹血糖检测于0.8～4.4 mmol/L间,其中4例低于2.8 mmol/L。DSA提示3例血供丰富或肿瘤染色。超声诊断仪为Aloka-650、EUB-40,探头频率为3.5MHz。检查方法为病人采用仰卧位、半卧位,禁食12小时,胃饮水充盈后,充分暴露胰腺头、体、尾部,及与周围大血管的关系,胰尾部检查可左侧卧位及借脾脏为透声窗。超声检查结果见附表,与病理诊断符合率为83％(5/6),超声定位与手术发现完全相符。
From January 1992 to December 1995, 6 patients with insulinoma were confirmed by surgery and pathology, including 4 males and 2 females, aged from 16 to 63 years. All six patients complained of seizure disorder, repeated syncope or convulsive coma, and sweating and palpitation. Preoperative fasting blood glucose was measured between 0.8 and 4.4 mmol/L, of which 4 were lower than 2.8 mmol/L. DSA prompted 3 cases with abundant blood supply or tumor staining. The ultrasonic diagnostic apparatus is Aloka-650, EUB-40, and the probe frequency is 3.5 MHz. The examination method was to use supine position, semi-recumbent position, fasting for 12 hours, filling of gastric juice, and to fully expose the head, body, tail of the pancreas, and the relationship with the surrounding large vessels. Pancreas tail examination can be left lying position and borrow spleen For the sound window. The results of the ultrasound examination are shown in the attached table. The coincidence rate with the pathological diagnosis was 83% (5/6). Ultrasound positioning was completely consistent with the surgical findings.
