Background: Minimally-invasive pancreato-biliary surgery (MIPBS) is increasingly reported worldwide. This study examines the changing trends, safety and outcomes associated with the adoption of MIPBS based on a contemporary experience of an early adopter in Southeast Asia. Methods: Retrospective review of 114 consecutive patients who underwent MIPBS by a single surgeon over 86 months from 2011. The study population was stratified into three equal groups of 38 patients. Comparison was also performed between minimally-invasive pancreato surgery (MIPS) and minimally-invasive biliary surgery (MIBS). Results: There were 70 MIPS and 44 MIBS. Sixty-three cases (55.3%) were performed using robotic assistance and fourteen (12.3%) were hybrid procedures with open reconstruction. Forty-four (38.6%) procedures were performed for malignancy. There were 8 (7.0%) open conversions and median operation time was 335 (range, 60–930) min. There were nine extended pancreatectomies including seven involving vascular reconstructions. Major morbidity (>Grade 2) occurred in 20 (17.5%) patients including 6 (5.3%) reoperations and there was no mortality. Comparison across the three groups demonstrated that with increasing experience, there was a significant trend in a higher proportion of higher ASA score patients, increasing frequency of procedures requiring anastomosis and increasing the use of robotic assistance without significant difference in key perioperative outcomes such as open conversion rate, morbidity and hospital stay. Comparison between MIPS and MIBS demonstrated that MIPS was associated with significantly longer operation time, increased blood loss, increased transfusion rate, longer hospital stay, increased readmission rate and increased morbidity. Conclusion: MIPBS can be safely adopted today with a low open conversion rate.
