Robotic Distal Gastrectomy Reduces Drain Amylase Values in Patients with a Small Pancreas-left Gastric Artery Angle

Abstract

Purpose: Pancreatic fistula is a severe complication after laparoscopic distal gastrectomy (LDG). We previously evaluated the pancreas-left gastric artery angle (PLA) as a risk indicator for developing a pancreatic fistula after LDG. This study evaluated the incidence of pancreatic fistula with robotic distal gastrectomy (RDG) in comparison to LDG from the view of the PLA. Materials and Methods: An association between the PLA and the incidence of pancreatic fistula in 165 patients who underwent either RDG (n=45) or LDG (n=120) was investigated retrospectively. Results: RDG patients had significantly lower drain amylase values (postoperative day 2) than LDG patients. As opposed to LDG patients, drain amylase values were similar for patients with small (PLA <62 degrees) and large (PLA ≥62 degrees) PLA in RDG patients. Conclusion: Robotic surgery may reduce the risk of postoperative pancreatic fistula in patients with a small PLA.
