Abstract
Background
Notable improvements in pancreatic cancer surgery have been due to utilization of the superior mesenteric artery (SMA)-first approach1 and triangle operation (clearance of triangle tissue between origin of SMA and celiac artery).2 The SMA-first approach was originally defined to assess resectability before taking the irreversible surgical steps. However, in the present era, resectability is judged by the preoperative radiology, and the benefit of the SMA-first approach is by improving the R0 resection rate and reducing blood loss. The basic principle is to identify the SMA at its origin and in the distal part, to guide the plane of uncinate dissection. This video demonstrates the combination of the posterior and right medial SMA-first approach along with triangle clearance during robotic pancreaticoduodenectomy (RPD).
Methods
The technique consisted of early dissection of SMA from the posterior aspect, by performing a Kocher maneuver using the ‘posterior SMA-first approach’. The origin of the celiac artery, along with the SMA, was defined early in the surgery. During uncinate process dissection, the ‘right/medial uncinate approach’ was used to approach the SMA. ‘Level 3 systematic mesopancreatic dissection’ was performed along the SMA,3 culminating in the ‘triangle operation’.2
Results
The procedure was performed within 600 min, with a blood loss of 150 mL and no intraoperative or postoperative complications. The final histopathology report showed a moderately differentiated adenocarcinoma (pT2, pN2), with all resection margins free.
Conclusion
The standardized technique of the SMA-first approach and triangle clearance during RPD is demonstrated in the video. Prospective studies should further evaluate the benefits of this procedure.
