Abstract Objective: To discuss the utilization of intraoperative ultrasound(IOUS) in pancreatic surgery and evaluate the clinical value. Methods: Imaging of CT, trans-abdominal ultrasound and IOUS in 14 cases of pancreatic surgery in our hospital from February 2007 to January 2010 were analyzed retrospectively. Surgical results were compared with pathological findings. Indications were mainly unclear preoperative diagnosis or location, complicated anatomy or contradiction between intraoperative palpation with the image data. Results: Fourteen cases included 4 cases of insulinoma, 4 cases of solid pseudopapillary tumor, 3 cases of pancreatitis, 1 case of adenocarcinoma, 1 case of pancreatic stone after cyst resection, 1 case with normal intraoperative biopsy result which gave up surgery. The detection rate of preoperative CT examination and transabdominal ultrasound was 92.3%(12/13) and 83.3%(10/12) respectively; and diagnostic accuracy was 71.4%(10/14) and 53.8%(7/13), respectively. All the lesions were detected by IOUS, with a better detection rate and better diagnostic accuracy compared with CT, and there was a significant difference between transabdominal ultrasound and IOUS. Laparoscopic surgery was changed to open surgery in 2 cases because of vascular invasion detected by IOUS. Conclusion: IOUS not only can improve detection and diagnostic rates of disease, but also guide surgical plan selection.
