Laparoscopic pancreaticoduodenectomy combined with major vascular resection and reconstruction:an analysis of 7 patients / 中华肝胆外科杂志

ABSTRACT

Objective To review our experience in laparoscopic pancreaticoduodenectomy combined with major vascular resection and reconstruction.Methods Of 183 patients who underwent laparoscopic pancreaticoduodenectomy in our department from November 2013 to January 2017,major vascular resection and reconstruction using the SMA first approach for total mesopancreas excision was performed in 7 patients.The clinical data of these 7 patients were retrospectively analyzed.Results Total 3D laparoscopic surgery was performed in all these 7 patients.The mean operation time,mean blood loss and blood flow occlusion time were (551.4 ± 83.8) min,(671.3 ± 256.3) ml and (45.8 ± 6.7) min,respectively.Six out of 7 patients were pathologically diagnosed to have pancreatic adenocarcinoma with negative surgical margins.Two patients had lymphatic metastasis (the number of metastatic lymph node was 1 in each patient).The mean number of lymph nodes resected was (12.7 ± 5.8).The portal vein-superior mesenteric vein (PV-SMV) was segmentally resected and reconstructed using an end to end anastomosis following the preoperative plan in 4 patients.These included 2 patients who underwent total pancreatectomy.The portal vein was wedge-resected and reconstructed by venorrhaphy in 2 patients.The remaining 1 patient was histopathologically diagnosed to have a mass-type chronic pancreatitis.Only 1 patient was treated in the ICU for 1 day after surgery.Post-operative complications occurred in 2 patients and they were managed with nonsurgical treatment (PV-SMV thrombosis and gastric emptying disorder in 1 and a pancreatic leakage (level A) in 1).The mean length of post-operative hospital stay was (13.7 ± 3.2) days with no in-hospital mortality.Seven patients were alive by April 2017.The mean follow-up for the 6 patients with pancreatic adenocarcinoma was 4.5 (3.5 ～9) months.Conclusions Based on our experience in skillful and masterly major vascular resection and reconstruction in open surgery and on our experience in standard laparoscopic pancreaticoduodenectomy,laparoscopic pancreatieoduodenectomy combined with major vascular resection and reconstruction was feasible and safe.This surgery requires very mature skills in laparoscopic surgery.
