Background Technical proficiency of the operating surgeons is one of the most important factors in the safe performance of pancreaticoduodenectomy. The objective of the present study was to investigate whether surgical simulation of pancreatico-jejunostomy (PJ) using an inanimate biotissue model could improve the technical proficiency of hepato-biliary pancreatic (HBP) surgical fellows. Methods The biotissue drill consisted of sewing biotissues to simulate PJ. The drill was repeated a total of five times by each of the participant surgical fellows. The improvement of the surgical fellows’ technical proficiency was evaluated by the supervisor surgeons using the Objective Structured Assessment of Technical Skills (OSATS) scale. Results Eight HBP surgical fellows completed all the 5 drills. Both the OSATS 25 score and OSATS summary score, assessed by the two supervisor surgeons, improved steadily with repeated execution of the PJ drill. The average OSATS score, as assessed by both the supervisor surgeons, improved significantly from the first to the final drill, with a P value of 0.003 and 0.014 for the assessment by the two surgeons, respectively. On the other hand, no chronological alteration was observed in time of procedure ( P = 0.788). Conclusion Repeated execution of a biotissue PJ drill improved the HBP surgical fellows’ technical proficiency, as evaluated by OSATS. The present study lends support to the evidence that simulation training can contribute to shortening of the time required to negotiate the learning curve for the technique of PJ in the actual operating room.
