The enhanced-view totally extraperitoneal repair of abdominal bulge after DIEP flap breast reconstruction for breast cancer: a case report

BackgroundThe deep inferior epigastric perforator (DIEP) flap for autologous breast reconstruction is associated with higher patient satisfaction and fewer abdominal morbidities at the donor site than the transverse rectus abdominis myocutaneous flap. However, abdominal bulging occurs at a certain frequency, and there is no established treatment. Here, we present a case of laparoscopic hernia repair using the enhanced-view totally extraperitoneal (eTEP) method in a patient with a lower abdominal bulge after DIEP flap reconstruction.Case presentation.A 53-year-old woman underwent left nipple-sparing mastectomy, left axillary lymph node dissection, and breast reconstruction with a DIEP flap for left breast cancer 3 years previously. We performed an eTEP method for an abdominal bulge. The absence of a hernia sac facilitated dissection of the retrorectal space, and a left-sided transversus abdominis release was performed, followed by mesh placement. No postoperative abdominal bulging was observed.BackgroundThe deep inferior epigastric perforator (DIEP) flap for autologous breast reconstruction is associated with higher patient satisfaction and fewer abdominal morbidities at the donor site than the transverse rectus abdominis myocutaneous flap.

No postoperative abdominal bulging was observed.ConclusionsUsing the eTEP method for repairing an abdominal bulge after DIEP flap reconstruction is advantageous because it facilitates a relatively straightforward dissection of a wide area of the retrorectal space without a hernia sac.
