The mean age of the patient was 38.5 years, and most of the tumors were stage 0 to 2 at the time of the operation. One breast prosthesis, two tissue expander with breast prosthesis, one latissimus dorsi musculocutaneous flap, eleven transverse rectus abdominis musculocutaneous (TRAM) flaps (conventional TRAM flap, bipedicle TRAM flap, super-charging TRAM flap, turbo-charging TRAM flap, free TRAM flap) were used for reconstruction. There were 5 postoperative complications; partial flap necrosis, hematoma, incisional hernia, seroma, fat necrosis, epigastric fullness. Our experiences of 15 cases of immediate breast reconstruction were presented with relatively short-term follow-up.
