BACKGROUND Radical surgery combined with systemic chemotherapy offers the possibility of long-term survival or even cure for patients with pancreatic ductal adenocar-cinoma(PDAC),although tumor recurrence,especially locally,still inhibits the treatment *** TRIANGLE technique was introduced as an extended dissection procedure to improve the R0 resection rate of borderline resectable or locally advanced ***,there was a lack of studies concerning postoperative complications and long-term outcomes of this procedure on patients with resectable *** Patients with resectable PDAC eligible for PD from our hospital between June 2.1. and December 2.2. were enrolled in this retrospective cohort *** the patients were divided into PDstandard and PDTRIANGLE groups according to the surgical *** characteristics,surgical data,and postoperative morbidities were *** of the patients were followed up,and the date and location of tumor recurrence,and death were *** Kaplan-Meier method and log-rank test were used for the survival *** There were 93 patients included in the study and 37 underwent the TRIANGLE *** of operation was longer in the PDTRIANGLE group compared with the PDstandard group[440(410-480)min vs 32.(2.5-42.)min](P=0.001).Intraoperative blood loss[700(500-12.0)mL vs 500(300-800)mL](P=0.009)and blood transfusion[975(0-12.0)mL vs 400(0-800)mL](P=0.009)were higher in the PDTRIANGLE *** was a higher incidence of surgical site infection(43.2.vs 12.5%)(P=0.001)and postoperative diarrhea(54.1%vs 12.5%)(P=0.001)in the PDTRIANGLE *** rates of R0 resection and local recurrence,overall survival,and disease-free survival did not differ significantly between the two *** The TRIANGLE technique is safe,with acceptable postoperative morbidities compared with standardized PD,but it does not improve prognosis for patients with resectable PDAC.
