Abstract

Background

Usage of intraoperative indocyanine green (ICG) to assess skin flaps prior to abdominal wall closure has been shown to decrease postoperative wound-related complications. Primary outcome assessed is the utility of ICG in intraoperative decision making. Secondary outcomes analyzed are the incidence of surgical site occurrence (SSO) and hernia recurrence rates.

Methods

A retrospective study using the MedStar Georgetown University Hospital database was conducted, incorporating all consecutive patients undergoing complex incisional hernia repair from 2008 to 2018. 146 patients underwent perforator-sparing component separation (PSCST), 88 underwent flap assessment using intraoperative ICG angiography; they were then analyzed based on patient comorbidities, Ventral Hernia Working Group grade, operative factors, and complications.

Results

A total of 146 patients were analyzed with no statistical difference in patient characteristics between the SPY and no SPY group except in BMI (30.2 vs. 33.2 kg/m2, p = 0.036). The no SPY group also had higher numbers of patients undergoing concurrent panniculectomy (12 vs. 1, p < 0.001), and extensive lysis of adhesions (30 vs. 31, p = 0.048). Of the 88 patients undergoing intraoperative SPY, 37 (42%) patients had a change of intraoperative management as defined by further subcutaneous skin flap debridement. Despite this change, there was no statistical difference in incidence of SSO between SPY and no SPY (24.3% vs. 11.8%, p = 0.12), and no difference in hernia recurrence rates 5.6% (n = 5) versus 13.7% (n = 8), p = 0.09.

Conclusion

Intraoperative ICG assessment of subcutaneous skin flaps with a perforator-sparing component separation does not result in a decrease in surgical site occurrences.
