[The Efficacy of 17 Cases of Pancreaticoduodenectomy Combined with Vascular Resection and Reconstruction by Using Robotic Operation System (with Video)].

ABSTRACT

OBJECTIVE: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.
