Interventional
Description of intervention(s) / exposure
Robotic-assisted middle pancreatectomy
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.Middle Pancreatectomy (MP) is a major surgical operation for borderline or benign tumor of pancreatic neck and body.
Approximate duration required to complete robotic-assisted
MP is about 200minutes.
Intervention code [1] 289899 0
Treatment: Surgery
Comparator / control treatment
Open middle pancreatectomy
Open middle Pancreatectomy (MP) is a major traditional surgical operation for borderline or benign tumor of pancreatic neck and body.
Approximate duration required to complete open MP is about 180minutes.
Control group
Active

Key exclusion criteria
(1) had severe underlying cardiopulmonary disease with poor heart and lung function, (2) could not tolerate anesthesia, (3) had a previous history of abdominal surgery that had resulted in severe abdominal adhesions, (4) scheduled for surgical treatment other than middle pancreatectomy such as distal pancreatectomy, (5) refusal to participate in or withdrawing from this study

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All patients voluntarily gave informed consent prior to participation in this study. Randomization was performed using consecutive sealed opaque envelopes which contained randomized numbers and occurred before surgery.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table from a statistic book
Masking / blinding
Open (masking not used)

Safety/efficacy
Statistical methods / analysis
The primary endpoint was the overall length of hospital stay (LOS), are calculated by subtracting day of admission from day of discharge. For the primary endpoint, estimates for standard deviation (SD) and minimal clinically relevant difference were derived from the existing literature. For the sample size calculation, a postulated time saving of 6 days was considered clinically relevant. The SD for postoperative hospital stay is known to be about 9 days. Calculations were based on a power of 80% and an a error of 5%, a number of at least 40 patients for each group was necessary. Anticipating a dropout rate of 10% and intended using nonparametric statistics, we increased the sample size to 50 patients per arm.The statistical software SPSS 19.0 (SPSS Inc., Chicago, IL, USA) was used for the statistical analysis. Continuous data are expressed as mean +/- standard deviation (SD) or median (interquartile range, IQR). Normally distributed variables were compared using the two independent samples Student t test. The Mann-Whitney U test was used for non-normally distributed variables. Categorical data were expressed as n (%) and compared using the chi-square test or Fisher’s exact test. Multivariate logistic regression analyses were performed for primary endpoint and pancreatic fistula, which were expressed as odd ratios (OR) with corresponding 95% confidence intervals (CI). A P-value less than 0.05 was considered statistically significant.
