Magnetic anastomosis has been attempted in continuous connection between bowel and bowel, vessels and vessels, biliary and gastrointestinal tracts, as well as in recanalization of the biliary stricture, and bilioenteric anastomotic stricture. During the past 15 years, the investigators have designed different types of magnets, and attempted these magnets in vascular, intestine, and biliary anastomosis in preclinical studies. In recent five years, we have successfully developed different types of magnets and utilized in biliojejunostomy, concomitant biliojejunostomy and pancreaticojejunostomy during Whipple. This study is designed as a prospective study by utilization of the bar-like magnets for pancreaticojejunostomy.
