title: A simple pancreaticojejunostomy technique for hard pancreases using only two transpancreatic sutures with buttresses: a comparison with the previous pancreaticogastrostomy and dunking methods.
abstract: OBJECTIVE
  In this study, we introduced a novel technique, the pancreaticojejunostomy (PJ), which uses only two transpancreatic sutures with buttresses (PJt), and compared the surgical outcomes with previously used methods, especially for hard pancreases.
  
  
  METHODS
  A total of 101 patients who underwent pancreaticoduodenectomy with hard pancreases were enrolled and divided into 3 groups according to the method of pancreaticoenteric anastomosis: 30 patients (29.7%) underwent the conventional dunking method (Du), 31 patients (30.7%) underwent pancreaticogastrostomy using transpancreatic sutures (PGt) and 40 patients (39.6%) underwent PJ using transpancreatic sutures (PJt). The surgical outcomes were compared according to the type of anastomosis to analyze the feasibility and ease of each technique.
  
  
  RESULTS
  The overall operative time was shorter in the PJt group (325.1 ± 63.8 minutes) than in the PGt group (367.3 ± 70.5 minutes) or the Du group (412.0 ± 38.2 minutes, P < 0.001). In terms of pancreaticoenteric anastomosis time, it was also shorter in the PJt group (10.3 ± 3.5 minutes) than in the Du group (20.7 ± 0.7 minutes) or the PGt group (16.8 ± 5.4 minutes, P = 0.005). Significant postoperative pancreatic fistula (POPF) developed in 2 cases (6.7%) in the Du group, whereas there were no POPF cases in the PGt or PJt groups (P = 0.086). Overall postoperative morbidities occurred in 31 cases (30.7%), and there were no significant differences among the 3 groups (P = 0.692).
  
  
  CONCLUSIONS
  The novel PJ technique, which uses only two transpancreatic sutures with buttresses, is a very simple, easy and secure method for hard pancreases and can be performed in a shorter amount of time compared with conventional methods.
