Background: Laparoscopic pancreatoduodenectomy (LPD) is a minimally invasive technique widely developed in the last few decades. Although magnetic compression anastomosis (magnamosis) is used during cholangiojejunostomy, its applicability in LPD has not yet been reported. Herein, we evaluated the feasibility and effectiveness of magnamosis in LPD.
Methods: Between January 2018 and December 2019, seven patients who underwent laparoscopic magnetic compression choledochojejunostomy (LMC-CJ) or laparoscopic magnetic compression pancreatojejunostomy (LMC-PJ) in LPD were enrolled. After LPD, a parent magnet with or without a drainage tube was placed in the proximal bile duct and pancreatic duct of each patient. Daughter magnets were introduced to couple with the parent magnets at the desired sites. A close postoperative surveillance of magnet movements was performed. Various relevant data were collected, and all patients were followed up until February 2020.
Results: LPD was successfully completed in all seven patients, of which seven underwent LMC-CJ and two received LMC-PJ. The median time needed for completion of LMC-CJ was 11 min (range, 8-16). The cost time for the two cases of LMC-PJ was 12 and 15 min, respectively. After a median time of 50 d (range, 40-170) postoperation, all magnets were expelled. No leakages of LMC-CJ or LMC-PJ were observed after operation. After a median follow-up period of 11 mo (range, 4-18), there was no incidence of anastomotic stricture.
