A Case of Intraparenchymal Insulinoma of the Pancreas Head Enucleated Successfully With Intraoperative Ultrasonography and Cusa

The rule of the surgical treatment of insulinoma is its perfect resection, but the localization of insulinoma is very important to select the operative procedure. We experienced recently an insulinoma that was detected by preoperative procedure and enucleated successfully with intraoperative ultrasonography (US) and CUSA (Cavitron. Ultrasonic Surgical Aspirator). A 28-year-old female had a cold sweat and numbness in the hands sometimes from the summer of 1991. In May, 1993, she was admitted to the hospital because of cold sweat and numbness in the whole body. An intraparenchymal insulinoma of the pancreas head was detected by abdominal US, CT, and angiography. The tumor was enucleated safely by using intraoperative US and CUSA at a low amplitude. There has been no evidence of recurrence in postoperative examinations.
