As deep inferior epigastric artery perforator (DIEP) flap surgery is gaining popularity, more patients including
Deep inferior epigastric artery perforator (DIEP) flap surgery is one of the gold standards of immediate breast reconstruction. As DIEP flap gains its popularity, there are cases requiring both DIEP flap and laparoscopic surgery. As laparoscopic surgeries and abdomen-based flap surgeries share the field and put the patient at risk of vascular damage, there is a need to standardize multidisciplinary strategy before the operation. The purpose of this report is to introduce our novel method of placing ports for laparoscopy and to share our experience in such cases.
A 45-year-old female patient, initially complained of a palpable mass in the right side of her breast, was diagnosed malignant spindle cell tumor which needed wide excision of skin on the superolateral side of the nipple. Supported by the patient’s own preference for autologous reconstruction, DIEP flap was selected. The patient underwent preoperative computed tomographic (CT) angiography and hand held Doppler analysis for mapping perforators. During evaluation, multiple uterine myoma with cystic change and secondary degeneration was found (
Elevation of flap was planned to use a left side contralateral perforator which was 6 cm from the umbilicus (
In the lithotomy position, an incision was made along the upper part of DIEP flap design and umbilicus. With adequate beveling of subcutaneous fat, dissection through the external oblique fascia was performed. A sufficient area near the umbilicus was dissected to allow initial trocar puncture, then an incision along the lower border of the flap design was also made, followed by avoiding injury to the superficial inferior epigastric vein (SIEV) (
Hysterectomy with salpingo-oophorectomy was performed without any unexpected events and with proper pneumoperitoneum. Thirty-five minutes of dissection was needed before trocar insertion, and it took 125 minutes to finish laparoscopic surgery. All of posterior fascia was closed, and the skin was sutured with a temporary stapler and Ioban drape (3M Corporate, St. Paul, MN, USA) was applied. The patient was repositioned and redraped. No perforator nor SIEV injury was observed during DIEP flap elevation.
The concurrent breast reconstruction and mastectomy with laparoscopic surgery was successfully completed and the patient discharged from hospital without any wounds or laparoscopy related complication. No additional postoperative care was needed and no other events or complications related to the surgery were noted after 6 months of follow-up in an outpatient clinic (
Some patients encounter the choice of whether to have concurrent laparoscopic surgery with DIEP flap.
As abdomen-based flap surgery directly shares its surgical field with laparoscopic surgeries, the possibility of vascular injury has been outlined by several studies [
There are few reports about concurrent surgery and abdomen-based flap procedures. Spear et al. [
The novel approach presented above has several advantages over the previous one. Because trocars are inserted after direct visualization of perforator vessel of flap above fascia level, the method definitely obviates the possibility of injury to the perforators and protect them from traction injury. Main pedicle, deep inferior epigastric artery, is also preserved easily as its location becomes more apparent. Moreover, there is no additional scarring on the upper abdominoplasty flap or DIEP flap. Otherwise, the injury of upper abdominal flap may lead to donor site dehiscence or necrosis. Also, as the safety of vasculature and the scar issue is guaranteed, it is possible to modify port placement to wherever surgeons feel comfortable for laparoscopic surgery, except a region where rectus muscle and main artery lies under external oblique fascia. If laparoscopic team closes fascia before elevation of flap, there is also a possibility of tearing the site during the elevation of the DIEP flap, which can be prevented in the novel method (
More cases are needed to establish the eligibility of the approach and to compare operation times or complications. Nonetheless, it could be uncomfortable for laparoscopic surgeons performing abdominal surgery because ports on the fascia could be unusual for them. A temporary skin stapler could alleviate this problem. Concerns over structural limitations due to the discomfort caused by involving multiple teams may be voiced in clinical practice but standardizing protocol will help to overcome such impediments.
In conclusion, simultaneous laparoscopic surgery can be successfully performed during DIEP flap elevation through the external oblique fascia. This method carries the advantage of a reduced risk of vascular damage and less surgical incision needed.
