    Abstract:
    OBJECTIVE: To investigate the technique of radical pancreaticoduodenectomy for malignant tumor in pancreatic head with pressed superior mesenteric blood vessel or portal vein. METHODS: From March 2005 to March 2007, thin slice scan and vessel-reconstruction of 56 patients of malignant tumor in pancreatic head with pressed superior mesenteric blood vessels or portal vein were carried out using multidetector spiral CT to evaluate whether peripheral vessels of pancreatic tumor were invaded and whether the tumor was resectable. During the operation, 3 vascular blocking bands for superior mesenteric vein, portal vein and spleen vein or 4 vascular blocking bands (additional one for inferior mesenteric vein) were preset. Under the cross and traction between superior mesenteric vein and superior mesenteric artery, resected the uncinate process of pancreas thoroughly. Using those methods, radical pancreaticoduodenectomy for 56 patients above-mentioned were successfully accomplished. RESULTS: The accuracy for preoperative judging by using multidetector spiral CT whether the peripheral vessels of pancreatic cancer were invaded and whether the tumor was resectable was 98% and 100% separately. Thirty-seven of 56 patients, whose superior mesenteric blood vessels or portal veins were pressed by the tumor of pancreatic head, were operated using 3 vascular blocking bands and 2 patients using 4 vascular blocking bands, followed by suturing the bleeding points of the superior mesenteric vein with 5-0 vascular suture Proline. One patient's superior mesenteric vein was partially resected and restored. The operations cost 5-8 h each and the blood loss was 200-600 ml. There were no operative or postoperative hemorrhage or pancreatic juice leakage. According to the follow-up up to now, 2 patients died of multiple live tumor metastases 7 and 9 months separately after operation, the other 54 patients were still alive. CONCLUSIONS: Thin slice scan and vessel-reconstruction using multidetector spiral CT can accurately judge whether the blood vessels near the pancreatic tumor were invaded and whether the tumor was resectable, using 3 vascular blocking bands or 4 vascular blocking bands and cross, traction of the superior mesenteric blood vessels, operator can easily accomplish the radical pancreaticoduodenectomy of malignant tumor in pancreatic head with pressed superior mesenteric blood vessels and portal vein, which was not resectable or need combined resection of the blood vessels in the traditional opinion.
