The postoperative pancreatic fistula (POPF) rate for duct‐to‐mucosa and invagination anastomosis after pancreatoduodenectomy is still debated. The aim of this RCT was to investigate the POPF rate for duct‐to‐mucosa
Patients were stratified by pancreatic texture and diameter of the main pancreatic duct and randomized to the duct‐to‐mucosa or invagination group. The primary endpoint was the rate of clinically relevant POPF (defined as grade B or C). Secondary endpoints were suture material cost for pancreaticojejunostomy, drain insertion duration and duration of postoperative hospital stay.
Some 120 patients undergoing pancreatoduodenectomy were included following consent. Clinically relevant POPF developed in six of 59 patients (10 per cent) in the invagination group and in 14 of 61 patients (23 per cent) in the duct‐to‐mucosa group (
This study did not demonstrate a superiority of invagination over duct‐to‐mucosa pancreaticojejunostomy in the risk of POPF. However, in high‐risk patients with a soft pancreas, invagination may reduce the risk of clinically relevant POPF compared with duct‐to‐mucosa. Registration number: UMIN000005890 (
