International survey on opinions and use of robot-assisted and laparoscopic minimally invasive pancreatic surgery: 5-year follow up

Abstract

Background: evidence on the value of minimally invasive pancreatic surgery (MIPS) has been increasing but it is unclear how this has influenced the view of pancreatic surgeons on MIPS. 

Methods: an anonymous survey was sent to members of eight international Hepato-Pancreato-Biliary Associations. Outcomes were compared with the 2016 international survey. 

Results: overall, 315 surgeons from 47 countries participated. The median volume of pancreatic resections per center was 70 (IQR 40–120). Most surgeons considered minimally invasive distal pancreatectomy (MIDP) superior to open (ODP) (94.6%) and open pancreatoduodenectomy (OPD) superior to minimally invasive (MIPD) (67.9%). Since 2016, there has been an increase in the number of surgeons performing both MIDP (79%–85.7%, p = 0.024) and MIPD (29%–45.7%, p < 0.001), and an increase in the use of the robot-assisted approach for both MIDP (16%–45.6%, p < 0.001) and MIPD (23%–47.9%, p < 0.001). The use of laparoscopy remained stable for MIDP (91% vs. 88.1%, p = 0.245) and decreased for MIPD (51%–36.8%, p = 0.024). 

Conclusion: this survey showed considerable changes of MIPS since 2016 with most surgeons considering MIDP superior to ODP and an increased use of robot-assisted MIPS. Surgeons prefer OPD and therefore the value of MIPD remains to be determined in randomized trials.
