Abstract

Bulge and hernia may occur after abdominally based breast reconstruction. The purpose of this study is to provide an estimate of the effects that the type of flap used for breast reconstruction (ie, transverse rectus abdominis muscle [TRAM] vs muscle-sparing [MS]-2 TRAM vs DIEP) has on the postoperative development of both abdominal bulge and abdominal hernia, taking into consideration the method of donor site closure (ie, with mesh vs without mesh), based on the available literature. Twenty-eight studies met the inclusion criteria and were included in the systematic review. From these, 9 studies were comparative and suitable for meta-analysis. The results showed that, for unilateral breast reconstructions, there was no statistically significant difference in hernia/bulge rates in the following techniques: MS-2 TRAM flap without mesh, MS-2 TRAM flap with mesh, and DIEP flap without mesh, and they showed significantly lower hernia/bulge rates compared with TRAM flap without mesh, and TRAM flap with mesh, whereas for bilateral reconstructions, there was no statistically significant difference in hernia/bulge rates in the following techniques: MS-2 TRAM flaps with mesh and DIEP flaps without mesh, and they showed significantly lower hernia/bulge rates compared with TRAM flaps without mesh, TRAM flaps with mesh, and MS-2 TRAM flaps without mesh.
