Role of tomoelastography in evaluation for pancreatic fistula after pancreaticoenteric anastomosis

This prospective study enrolled the patients who underwent both preoperative tomoelastography and pancreaticoenteric anastomosis. Eighty-two patients were included (median age: 59.5 years, 40 men, 18 patients with POPF). Main pancreatic duct diameter (MPDD) (P=0.012), c (P<0.001) and φ (P=0.001) were relevant factors for POPF. The area under the curve (AUC) of c, φ and MPDD for predicting POPF was 0.880, 0.816 and 0.747. Fibrosis was the relevant factor of POPF (P=0.001). There was positive correlation between fibrosis and stiffness (r=0.681, P<0.001). Tomoelastography is a novel and robust multi-frequency MRE technique that can facilitate the prediction of POPF.
