OBJECTIVE: To compare the short-term outcomes of pancreaticojejunostomy (PJ) and pancreatic duct occlusion (PDO) in patients at intermediate-high risk of postoperative pancreatic fistula (POPF).
SUMMARY BACKGROUND DATA: Postoperative pancreatic fistula (POPF) is the most fearsome complication of pancreaticoduodenectomy (PD).
METHODS: Patients undergoing PD with intermediate-high fistula risk scores (FRS) at two tertiary centers between 2012 and 2022 were included. To reduce biases between the groups, entropy balance and inverse probability of treatment weighting (EB-IPTW) were used.
RESULTS: A total of 302 patients were included (224, 74.2% PJs and 78, 25.8% PDOs). After EB-IPTW, two weighted pseudo-populations of 224 patients were obtained. Major complications, POPF, reoperations and post-operative mortality were similar. Patients undergoing PDO had lower rates of grade C POPF (3.3% vs. 6.7%), delayed gastric emptying (15.7% vs. 24.6%, P=0.02), intra-abdominal collections (7.3% vs. 20.5%, P<0.001) and 90-day readmissions (2.7% vs. 9.4%, P=0.005). In subgroup analysis, PDO reduced POPF in patients with high FRS and blood loss >400 mL, while PJ was more effective in intermediate FRS class, duct diameter ≥2 mm, blood loss <400 mL, ASA class >II, younger patients and BMI <25 kg/m2. In the unbalanced cohorts, completion pancreatectomy was required in 10 (4.5%) patients after PJ and in 1 (1.2%) after PDO.
CONCLUSION: The main perioperative outcomes of PJ and PDO after PD in intermediate-high risk FRS patients are similar. PDO decreases the rate of POPF in patients with high-risk FRS, and reduces the need of completion pancreatectomy in case of reoperation.
