Prevention of Petersen’s hernia using jejunal mesentery fixing (Mefix)

The aim of this study was to compare the 1 year incidence of Petersen’s hernia between individuals who were treated with the jejunal mesentery fixing (Mefix) method and those with the closure of Petersen’s space method. We retrospectively collected clinical data of patients who underwent gastrectomy for gastric cancers with the closure of Petersen’s space defect (<i>N</i> = 49) and Mefix (<i>N</i> = 26). The Mefix method was performed by fixing the jejunal mesentery (jejunojejunostomy below 30 cm) to the transverse mesocolon using nonabsorbable barbed sutures. The procedure time for mesentery fixing (3.7 ± 1.1 mins) was significantly shorter than that for Petersen’s space closure (7.5 ± 1.5 mins) (<i>p</i> We found no occurrence of Petersen’s hernias postoperatively in either group. We also found that the Mefix method was faster and easier to perform than the closure method. The Mefix method is an excellent alternative method to prevent the occurrence of Petersen’s hernia after B-II or Roux-en-Y reconstruction.
