An end-to-side suspender pancreaticojejunostomy: A new invagination pancreaticojejunostomy.

BACKGROUND: Postoperative pancreatic fistula (POPF) is a severe complication of the pancreaticoduodenectomy (PD). Recently, we introduced a method of suspender pancreaticojejunostomy (PJ) to the PD. In this study, we retrospectively analyzed various risk factors for complications after PD. We also introduced and assessed the suspender PJ to demonstrate its advantages.

METHODS: Data from 335 patients with various periampullary lesions, who underwent the Whipple procedure (classic Whipple procedure or pylorus-preserving) PD by either traditional end-to-side invagination PJ or suspender PJ, were analyzed. The correlation between either perioperative or postoperative complications and corresponding PD approaches was evaluated by univariate analysis.

RESULTS: A total of 147 patients received the traditional end-to-side invagination PJ, and 188 patients were given the suspender PJ. Overall, 51.9% patients had various complications after PD. The mortality rate was 2.4%. The POPF incidence in patients who received the suspender PJ was 5.3%, which was significantly lower than those who received the traditional end-to-side invagination PJ (18.4%) (P < 0.001). Univariate analysis showed that PJ approach and the pancreas texture were significantly associated with the POPF incidence rate (P < 0.01). POPF was a risk factor for both postoperative abdominal cavity infection (OR = 8.34, 95% CI: 3.99-17.42, P < 0.001) and abdominal cavity hemorrhage (OR = 4.86, 95% CI: 1.92-12.33, P = 0.001).

CONCLUSIONS: Our study showed that the impact of the pancreas texture was a major risk factor for pancreatic leakage after a PD. The suspender PJ can be easily accomplished and widely applied and can effectively decrease the impact of the pancreas texture on pancreatic fistula after a PD and leads to a lower POPF incidence rate.
