胰腺内分泌肿瘤以胰岛素瘤和胃泌素瘤最为多见.胰岛素瘤术中触诊不能定位者达20%,借助术中超声检查检出率亦不到10%.胃泌素瘤因可能位于胰腺外组织,术中不能找到者高达40%.术前应用传统的超声、CT和血管造影等影像学方法定位,因其肿瘤往往很小,约10%～30%不能检出,不得不依赖于手术探查及术中超声检查.若术前肿瘤能获定位,则可大大提高手术成功率.作者总结胰腺内分泌肿瘤37例,包括肿瘤灶39个.所有肿瘤均经手术切除和免疫组织学
Insulinomas and gastrinomas are the most common pancreatic endocrine tumors. Insulinomas can not be located in 20% of patients with palpation, and the detection rate by intraoperative ultrasound is less than 10%. Gastrinomaoma may be located in the pancreas. Out-of-tissue, up to 40% can not be found during surgery. Preoperative application of conventional ultrasound, CT and angiography and other imaging methods, because the tumor is often very small, about 10% to 30% can not be detected, had to rely on Surgical exploration and intraoperative ultrasound examination. If the preoperative tumor can be located, it can greatly improve the success rate of surgery. The authors summarized 37 cases of pancreatic endocrine tumors, including 39 tumor foci. All tumors were surgically removed and immunohistochemistry.
