Introduction:
Robot-assisted surgery is a promising technique for overcoming the limitations of laparoscopic surgery, especially for complex and advanced surgical procedures. We now describe the implementation of our robotic upper GI and HPB surgery program in our centre of excellence for minimally invasive surgery and the results of our first 100 surgical procedures.
Method:
Robot-assisted surgery was performed using the Da Vinci® Xi Surgical System™. Robot-assisted surgical procedures were performed by two surgeons specialising in minimally invasive surgery. Our robotic surgery program for upper GI and HPB surgery was established in three steps. Step 1: firstly, relatively easy surgical procedures were performed robotically, including cholecystectomies, minor gastric resections and fundoplications. Step 2: secondly, pancreatic left sided resections, adrenalectomies and small liver resection were performed, as procedures with moderate degree of difficulty. Step 3: finally, advanced and highly complex procedures were performed, including right hemihepatectomy, complex pancreatic resections, total gastrectomies and oesophagectomies. Data collected from July 2017 till October 2018 were analysed retrospectively with regard to conversion rate, morbidity (Clavien Dindo > 2) and 90-d-mortality.
Results:
The first step of establishing our robotic surgical program included 26 procedures. Here, conversion rate, morbidity and mortality were 0%. In the second step of implementation, 23 procedures were performed. Conversion rate, morbidity and mortality were 28, 8 and 0% respectively. The last step included 51 advanced and highly complex procedures. These procedures had a morbidity of 41%, a mortality of 4% and a conversion rate of 43%.
Conclusion:
Our stepwise approach enables safe implementation of a robotic surgical program for upper GI and HPB surgery with comparable morbidity and mortality even for highly complex procedures. However, highly complex procedures in the learning curve required a high conversion rate.
