Description of intervention(s) / exposure
Robotic-assisted pancreaticoduodenectomy
Robot-assisted laparoscopy is the most advanced minimally invasive surgery technique characteristic of a magnified three-dimensional visualization and endowrist instruments with greater range of motion.Pancreaticoduodenectomy (PD) is a major surgical operation involving the pancreas, duodenum, and pylorus in most cases.
Approximate duration required to complete robotic-assisted pancreaticoduodenectomy is about 410minutes.
Intervention code [1] 288936 0
Treatment: Surgery
Comparator / control treatment
Open pancreaticoduodenectomy
Pancreaticoduodenectomy (PD), also called Whipple procedure, is a major surgical operation involving the pancreas, duodenum, and pylorus in most cases first described in 1938 for treating borderline or malignant pancreatic head, common bile duct, and duodenal pathologies.
Approximate duration required to complete open pancreaticoduodenectomy is about 315 minutes.

Can healthy volunteers participate?
No
Key exclusion criteria
Having an excessively large lesion (tumor size >10 cm) invading adjacent organs and major vessels; involvement of superior mesenteric vein or portal vein (PV) longer than 3 cm possibly requiring interposed graft reconstruction, for which OPD was determined to be more suitable than RLDP; scheduled for surgical treatment other than PD, such as palliative biliary and gastroenteric anastomoses; presence of complicating serious cardiopulmonary or hepatorenal insufficiency; extensive intraperitoneal or extraperitoneal metastases; and refusal to participate in or withdrawing from this study.

Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The RLPD group was matched with the OPD group at a ratio of 1:2 using a matching patient’s algorithm according to age (within ± 5 years), sex, body mass index (BMI; <18.5 versus 18.5–24.9 versus 25.0–29.9 versus = 30 kg/m2), American Society of Anesthesiologists (ASA) physical status classification (I versus II versus III), and malignancy (malignant vs. non-malignant), location (pancreas versus distal common bile duct versus periampullary region) and size of tumor. The matching process was verified every 2 enrolments in the RLPD group to allow targeted recruitment into the OPD group. All patients included were well informed of the advantages and disadvantages of RLPD and OPD by independent research nurses. All patients voluntarily gave written informed consent for participation in this study.

Statistical methods / analysis
The statistical software SPSS 19.0 (SPSS Inc., Chicago, IL, USA) was used for the statistical analysis. Continuous data were expressed as mean +/- standard deviation (SD), and the means were compared using the two independent samples Student-t test. Categorical data were expressed as n(%) and compared using the Fisher’s exact probability test. The Mann-Whitney U test was used for non-normally distributed variables. The linear regression was used to analyze whether demographic growth exhibited significance. The Spearman rank correlation coefficient was used to determine whether operative time, bleeding volume and morbidity rate exhibited significant ‘‘learning curves’’. Survival analysis was performed using the time between the date of surgery and the date of last follow-up or death. Survival curves were computed using the Kaplan-Meier method and compared between groups by the log-rank test. A P-value less than 0.05 was considered statistically significant.

Summary
Brief summary
Robot-assisted laparoscopic pancreaticoduodenectomy (RLPD) is a novel minimally invasive surgery technique. None of prospective studies of large sample size comparing RLPD and OPD have been presented and long-tern oncologic outcome is lacking.This study aimed to prospectively evaluate the effectiveness and advancement of RLPD versus open PD (OPD).
