[The Efficacy of 17 Cases of Pancreaticoduodenectomy Combined with Vascular Resection and Reconstruction by Using...

To explore the clinical efficacy of pancreaticoduodenectomy (PD) combined with vascular resection and reconstruction under robotic surgery system in the treatment of borderline resectable pancreatic cancer.

The clinical data of 17 patients with borderline resectable pancreatic cancer who underwent PD combined with vascular resection and reconstruction (see the Video 1 in Supplemental Contents, http://ykxb.scu.edu.cn/article/doi/10.12182/20200760202) under robotic surgery system between August 2011 and September 2018 was analyzed retrospectively.

There were 4 cases required conversion because of serious tumor invasion and soft pancreas texture, the other 13 cases were successfully completed. 16 cases (94%) achieved margin-negative resection (R0 resection), 14 cases combined with vein resection, and 3 cases combined with arterial resection. The mean operation time was (401±170) min, the mean blood loss was (647±345) mL, the mean postoperative length of hospital stay was (20±8) d. There was no perioperative death. Postoperative pathology findings and follow-up outcomes were as follows: 1 patient was diagnosed as intraductal papillary mucinous neoplasm (IPMN) and 1 patient was diagnosed as pancreatic neuroendocrine tumors (PNET) (Grade 1), 8 patients with pancreatic ductal adenocarcinoma (PDAC). 1 patient with pancreatic neuroendocrine carcinoma (PNEC) died because of tumor recurrence and metastasis during the follow-up period, the median (Min-Max) survival time was 12 (8-26) months. 5 patients with PDAC and 1 patient with malignant IPMN were currently in the follow-up period.

It is safe and feasible to perform RPD with vascular resection and reconstruction. The patient's condition should be fully evaluated before surgery to select the most appropriate treatment.
