Figure 4: The gastric wall defect is shown in Figure 4A. The closure of the defect by a multiblock copolymer in the implantation group is presented in Figure 4B.
A standardized gastrotomy with a diameter of 10 mm was performed at the ventral side of the stomach between the smaller and the greater curvatures. The defect of the gastric wall is marked by an arrow (Figure 4A). In the implantation group the defect was closed with a copolymer patch (diameter 10 mm; thickness 200 µm). The defect closure by a copolymer patch is marked by an arrow (Figure 4B). The copolymer patch was sutured into the gastric wall defect with a monofil, non-resorbable 8/0 thread in a non-interrupted sero-muscular technique.
