Aim of study. Investigation of risk factors in development of postoperative pancreatic fi stula (POPF) in patients aft er distal pancreatectomy (DP) involving application of a cutting stapler device (CS) as well as determination of the criteria for selection of the optimal cassette type for such devices making it possible to reduce the POPF development frequency. Material and methods. A two-centre retrospective/prospective controlled study was performed. A total of 46 patients (19 (41.3 %) male and 27 (58.7 %) female) were enrolled. All patients included in the study underwent DP surgery using CS for excision of the pancreas with closure of its stump. In all cases, measurement of the pancreas thickness in the resection area based on the data of preoperative computed tomography and calculation of the difference between the pancreatic parenchymal thickness in the resection area and the staple closure height (SCH). Th e patients were distributed between two groups: 1) without POPF of with biochemical leakage (BL); 2) with clinically relevant POPF (CR-POPF). Results. CR-POPF developed in 15 (32.6 %) cases (type-B POPF: 14 (93.3 %) cases, type-С: 1 (6.7 %) case). Statistically signifi cant diff erence in mean pancreatic parenchymal thickness in the resection area as well as mean SCH between the group without POPF or with BL and the group with CR-POPF (15.4±4.3mm versus 12.3±3.5mm, р=0.01 and 12.8±2.3mm versus 16.4±3.1mm, р<0.01, respectively). Th e frequency of CR-POPF development was reliably lower at the SCH varying from 8 to 14mm (9.5 %) as compared to cases with SCH below 8mm (55.6 %, p<0.01) and above 14mm (50.0 %, p<0.01). Conclusion. Upon analysis of risk factors in POPF development aft er DP, it has been established that a greater pancreatic parenchymal thickness in the resection area as well as SCH are statistically significant risk factors for this complication. Th e optimal SCH making it possible to achieve the minimal frequency of POPF aft er pancreatic stump closure using a CS is within the range of 8-14mm.
