Intraoperative use of fluorescent imaging with indocyanine green changes management of abdominal wall flaps during open ventral hernia repair

Abstract

Background

Wound complications including infection and necrosis remain common during complex open ventral hernia repair. Advancements or enhancements in imaging technology may abate some of these issues but requires more investigation. Laser-assisted fluorescent imaging with indocyanine green (Spy Elite, LifeCell Corporation, Branchburg, NJ) allows visualization and quantification of perfusion, facilitating management of poorly perfused tissue.

Methods

Ten patients, who underwent large or massive ventral or incisional hernia repair with biologic graft reinforcement and either perforator-sparing components separation or primary open repair, underwent intraoperative laser-assisted fluorescent imaging with indocyanine green from August 2012 to August 2013. The cases were reviewed by an independent data collector with primary outcomes of postoperative skin infection and/or abdominal wall necrosis.

Results

Three (30 %) patients had adequate perfusion, while seven (70 %) patients had inadequate skin perfusion and necessitated excision of additional tissue. Of the patients whose ischemic tissue was removed, four (57 %) patients had an infection and no patients developed necrosis postoperatively. Of the patients who had no removal of additional skin, one (33 %) patient developed an infection and one (33 %) patients developed skin necrosis.

Conclusion

The intraoperative use of laser-assisted fluorescent imaging with indocyanine green may change management of abdominal wall flaps, even in perforator-sparing operations. Our study series is small and cannot suggest statistical significance in the potential benefit of intraoperative imaging, but shows that up to 70 % of patients may require change in management due to poorly perfused tissue flaps.
