Outcomes of robotic surgery for pancreatic ductal adenocarcinoma

Authors introduction： Qian Zhan, female, who was born in Sept, 1979. She studied in the Shanghai Second Medical University during 1998 to 2005. She majored in Clinical Medicine, and earned her master degree in 2005. In 2005, she went to the Beaujon Hospital of Paris 7th Universit3. in France, as a foreign intern. Later, she came to postgraduate work and residencies in the general surgery department of Shanghai Ruijin Hospital. Her clinical work is focused on multidisciplinary especially postoperative management for the patients with pancreatic cancer. In addition, she is a lead researcher in the pancreatic cancer group for nano based drug delivery, systems. Chenghong Peng, male, who was born in Apr, 1957. He worked in the 2nd Affiliated Hospital of Zhejiang University School of Medicine during 1989 to 2002. In 2002, Chenghong Peng came m Shanghai Ruiiin Hospital and began to take charge of general surgery department. As a pioneer in the hepatobifiopancreatic field, Chenghong Peng devoted himself in the basic and clinical research of pancreatic tmnors. He brings forth new ideas by creating ＂Pancreatic multiple treatment collaborating groups＂, which integrate the advantages of gasn＇oenterology, department, endoscopy department, radiology department, pathology deparnnent and SICU. He constantly strives for excellence in pancreatic surgery. In the previous five years, he performed more than 300 cases of pancreatectomy each year, and has accomplished more than 2,000 cases of pancreatectomy altogether, among which the resectable rate is 74%. Besides, he is also committed to laparoscopic surgery and robotic surgeD,. He has achieved more than 200 laparoscopic hepatectomies, 150 laparoscopic pancreatectomies and 500 robotic hepatobiliopancreatic surgeries （350 robotic pancreatic surgeries included）, which keeps leading position in China. In 2011, Chenghong Peng has won the first prize in 3rd international congress of CRSA, which marked that our achievement in robotic surgery was recognized by oversea peers.Background： To explore the effectiveness, safety, and efficacy of the robot-assisted surgery in the radical resection of pancreatic ductal adenocarcinoma （PDAC）. Methods： The clinical data of 72 patients with PDAC who underwent radical resection using the da Vinci Surgical System from April 2010 to December 2014 were retrospectively analyzed. Results： Among these 72 patients, three were converted to conventional laparotomy due to the vascular invasion or due to t
