Abstract

PURPOSE: Pancreatic fistulas are a leading cause of mortality and morbidity following pancreaticoduodenectomy. The objective of this study was to evaluate the possibility of controlling pancreatic fistula formation by binding pancreaticojejunostomy into the operative procedure, as proposed by Peng, which results in a 3 cm invagination of the pancreatic remnant by the jejunal segment bearing electrically-destroyed mucosa reinforced by inner and outer sutures.
METHODS
Prospectively collected data of patients undergoing pancreaticoduodenectomy in the Department of Surgery of Daejeon St. Mary's hospital between April 2007 and May 2009 were analyzed retrospectively. Thirty-one patients were included in the study; 16 patients underwent dunking pancreaticojejunostomy and 15 patients underwent binding pancreaticojejunostomy.
RESULTS
The two groups were comparable with respect to demographic data, pre-operative characteristics, underlying pathologies, pancreatic textures, and duct diameters. The mean operative time did not differ between the two groups (388+/-29 min vs. 459+/-21 min, p=0.060). No difference existed in the post-operative course except for the degree of complications. In contrast to the dunking group, in which 2 cases of grade III/V pancreatic fistulas occurred, the binding group had no severe complications. In addition, transformation of amylase data measured from Jackson-Pratt drains into a natural logarithm demonstrated significant differences on post-operative (POD) days 1, 3, and 7 between the dunking and binding groups (POD1, 6.97+/-0.41 vs. 6.10+/-0.44 [p=0.037]; POD3, 6.97+/-0.41 vs. 6.10+/-0.44 [p=0.032]; POD7, 4.69+/-0.35 vs. 3.88+/-0.25 [p=0.034], respectively).
CONCLUSION
Bindning pancreaticojejunostomy is equivalent to dunking pancreaticojejunostomy with respect to operative difficulties, and more effective in preventing complications related to pancreatic fistulas.
