The new JSS is useful and easier to use for the prediction of prognosis compared to the conventional scoring systems. EN was effective in reducing the mortality rate in patients with a new JSS >or= 4.

Background Postoperative pancreatic fistula (POPF) after distal pancreatectomy (DP) remains the most common surgical complication. We have developed a novel stump closure technique after DP using transpancreatic mattress suture with Vicryl mesh (TMV) and reported our initial findings. The purpose of this study is to evaluate the efficacy of TMV compared to the conventional handsewn stump closure technique (CHS). Methods This retrospective single-center study included 165 consecutive patients who underwent open DP from January 2010 to May 2018. Of these, 71 patients underwent DP using TMV after September 2014 and 94 patients underwent DP with CHS. The surgical outcomes were compared between the two groups. Results Clinically relevant POPF rate in the TMV group was significantly lower than that in the CHS group (5.6% vs. 17.2%, P = 0.027). Morbidity rate was higher in the CHS group than that in the TMV group (16.9% vs. 27.7%, P = 0.104). In the multivariate analysis, absence of additional organ resection (OR 3.57; 95% CI 1.18-10.43; P = 0.025) and TMV (OR 0.24; 95% CI 0.07-0.73; P = 0.010) were identified as independent preventing factors for clinically relevant POPF. Conclusion TMV can be an effective stump closure technique for preventing POPF after DP.
