ABSTRACT
BACKGROUND: The ideal technical pancreatic reconstruction following pancreaticoduodenectomy (PD) is still debated. The aim of the study was to assess the surgical outcomes of duct to mucosa pancreaticojejunostomy (PJ) (G1) and invagination PJ (G2) after PD. METHODS: Consecutive patients treated by PD at our center were randomized into either group. The primary outcome measure was the rate of postoperative pancreatic fistula (POPF); secondary outcomes included; operative time, day to resume oral feeding, postoperative morbidity and mortality, exocrine and endocrine pancreatic functions. RESULTS: One hundred and seven patients treated by PD were randomized. The median operative time for reconstruction was significantly longer in G1 (34 vs. 30 min, P=0.002). POPF developed in 11/53 patients in G1 and 8/54 patients in G 2, P=0.46 (6 vs. 2 patients had a POPF type B or C, P=0.4). Steatorrhea after one year was 21/50 in G1 and 11/50 in G2, respectively (P=0.04). Serum albumin level after one year was 3.4 gm% in G1 and 3.6 gm in G2 (P=0.03). There was no statistically significant difference regarding the incidence of DM preoperatively and one year postoperatively. CONCLUSION: Invagination PJ is easier to perform than duct to mucosa especially in small pancreatic duct. The soft friable pancreatic tissue can be problematic for invagination PJ due to parenchymal laceration. Invagination PJ was not associated with a lower rate of POPF, but it was associated with decreased severity of POPF and incidence of postoperative steatorrhea. CLINICAL TRIALS. GOV ID: NCT02142517.

OBJECTIVES: The optimal strategy for the reconstruction of the pancreas following pancreaticoduodenectomy (PD) is still debated. The aim of this study was to compare the outcomes of isolated Roux loop pancreaticojejunostomy (IRPJ) with those of pancreaticogastrostomy (PG) after PD. METHODS: Consecutive patients submitted to PD were randomized to either method of reconstruction. The primary outcome measure was the rate of postoperative pancreatic fistula (POPF). Secondary outcomes included operative time, day to resumption of oral feeding, postoperative morbidity and mortality, and exocrine and endocrine pancreatic functions. RESULTS: Ninety patients treated by PD were included in the study. The median total operative time was significantly longer in the IRPJ group (320 min versus 300 min; P = 0.047). Postoperative pancreatic fistula developed in nine of 45 patients in the IRPJ group and 10 of 45 patients in the PG group (P = 0.796). Seven IRPJ patients and four PG patients had POPF of type B or C (P = 0.710). Time to resumption of oral feeding was shorter in the IRPJ group (P = 0.03). Steatorrhea at 1 year was reported in nine of 42 IRPJ patients and 18 of 41 PG patients (P = 0.029). Albumin levels at 1 year were 3.6 g/dl in the IRPJ group and 3.3 g/dl in the PG group (P = 0.001). CONCLUSIONS: Isolated Roux loop PJ was not associated with a lower rate of POPF, but was associated with a decrease in the incidence of postoperative steatorrhea. The technique allowed for early oral feeding and the maintenance of oral feeding even if POPF developed.
