Background:
A stent often is placed across the pancreaticojejunostomy. However, there is no report compared between internal drainage and external drainage.
Methods:
We conducted a prospective randomized trial (NCT00628186 registered at http://ClinicalTrials.gov) with 100 patients who underwent pancreaticoduodenectomy and we compared the effects on postoperative course.
Results:
The incidence of pancreatic fistula according to the International Study Group on Pancreatic Fistula criteria was not different (external, 20%; vs internal, 26%), and the incidence of the other complications was similar between stent types. The median postoperative hospital stay was 21 days (range, 8-163 d) in the internal drainage group, which was shorter than the median stay of 24 days (range, 21-88 d) in the external drainage group (P = .016).
Conclusions:
Both internal drainage and external drainage were safety devices for pancreaticojejunostomy. Internal drainage simplifies postoperative managements and it might shorten postoperative stay for pancreaticoduodenectomy.
