ARTICLE HIGHLIGHTS
Research background
Robotic pancreaticoduodenectomy (RPD) can achieve similar surgical results to open and PD; however, RPD has a long learning curve and operation time (OT).
Research motivation
To address this issue, we have summarized a surgical path to shorten the surgical learning curve and OT.
Research objectives
This study aimed to investigate the efficacy and learning curve of a “G”-shaped surgical approach in RPD.
Research methods
A total of 60 patients, who received “G”-shaped RPD (GRPD) by a single surgeon in the First Hospital of Shanxi Medical University from May 2017 to April 2020, were included in this study. OT, demographic data, intraoperative blood loss, complications, hospitalization time, and pathological results were recorded, and the cumulative sum (CUSUM) analysis was performed to evaluate the learning curve for GRPD.
Research results
According to the CUSUM analysis, the learning curve for GRPD was grouped into two phases (early and late phases). The OT was 480 ± 81.65 min vs 331 ± 76.54 min, hospitalization time was 22 ± 4.53 d vs 17 ± 6.08 d, and blood loss was 308 ± 54.78 mL vs 169.2 ± 35.33 mL in the respective groups. The complications, including pancreatic fistula, bile leakage, reoperation rate, postoperative death, and delayed gastric emptying, were significantly decreased after this surgical technique.
Research conclusions
GRPD can improve the learning curve and operative time, and this will provide a new method for shortening the RPD learning curve.
Research perspectives
GRPD can improve the learning curve and operative time, and this will provide a new method for shortening the RPD learning curve.
