As deep inferior epigastric artery perforator (DIEP) flap surgery is gaining popularity, more patients including BRCA-positive patients need simultaneous laparoscopic surgery. We share our experience on a patient who underwent concurrent laparoscopic hysterectomy during flap elevation with a novel method. A patient diagnosed with a right breast cancer also required laparoscopic hysterectomy due to multiple uterine myoma. After perforator mapping was performed, flap elevation through external oblique fascia level was carried out first, sparing the periumbilical perforator and superficial inferior epigastric vein. Three ports were inserted for laparoscopy on posterior fascia level in the periumbilical area, left upper quadrant area and suprapubic area. The surgery was completed without any complication, gas leaks or vascular injury with the advantage of reduced risk of vascular damage and less surgical incision.
