Appraisal of the Imaizumi modification of the Beger procedure: the TWMU experience.
OBJECTIVE
We developed the Imaizumi modification of the Beger procedure, a duodenum-preserving pancreatic head resection. The Imaizumi modification allows for removal of more of the subtotal pancreatic head than in the conventional Beger procedure, including the intrapancreatic bile duct, for chronic pancreatitis with common bile duct stenosis. A retrospective study was performed to evaluate the efficacy of the Imaizumi modification compared to a pylorus-preserving pancreaticoduodenectomy (PPPD), based on the early and late postoperative results.


METHODS
A group of 14 patients who underwent the Beger procedure with the Imaizumi modification to treat chronic pancreatitis from November 1997 to December 2005 was investigated retrospectively. This group was compared to a group of 21 patients who underwent PPPD from November 1997 to December 2003. The median follow-up period was 3.6 years (range 3.1-5.7 years) for the Imaizumi modification group and 4.0 years (range 3.0-8.3 years) for the PPPD group.


RESULTS
A pancreatic fistula formed in 7% of the Imaizumi modification patients (PPPD 5%), pain relief was achieved in 92% (PPPD 94%), complete professional rehabilitation was achieved in 71% (PPPD 67%), insulin-dependent diabetes mellitus was present in 43 versus 36% before the procedure (PPPD 62 versus 38% before the procedure), and body weight improved in 79% (PPPD 48%). No significant differences were found between the two groups for the early postoperative complications and the late postoperative outcome 3 years after the procedure. However, the Imaizumi modification group exhibited an encouraging tendency to have a lower rate of new-onset exocrine and endocrine insufficiency than the PPPD group.


CONCLUSIONS
Our Imaizumi modification of the Beger procedure, including intrapancreatic bile duct resection, represents a useful alternative for the treatment of chronic pancreatitis with an inflammatory mass and bile duct stenosis in the pancreatic head.
