Indocyanine green does not decrease the need for bail-out operation in an acute care surgery population.

BACKGROUND

The use of indocyanine green during laparoscopic cholecystectomy has been postulated to help to define anatomy. Studies have not specifically evaluated patients with acute cholecystitis. We sought to assess whether use of indocyanine green can decrease the rate of bail-out operation (subtotal cholecystectomy or conversion to an open operation) in an acute care surgery population where acute cholecystitis is more frequent.

METHODS

Using a retrospective cohort design, we examined all inpatient cholecystectomies performed by the acute care surgery service under urgent or semiurgent (biliary colic as the presentation in the emergency room) conditions at a single institution from 7/1/18 to 6/30/19 during which indocyanine green was available for use at the surgeon's discretion.

RESULTS

A total of 198 patients were included in the analysis. Demographic variables were similar in groups receiving indocyanine green versus not. Pathology confirmed acute cholecystitis was present in 96 of 198 (48.5%) patients; of those, 55 (57.2%) received indocyanine green. Indocyanine green did not change the rate of bail-out operation between patients who received indocyanine green and those who did not (6.7% vs 4.3%, P = .468). No significant differences in complications were observed. Bail-out operation was more likely in cases of acute cholecystitis (9.4%) versus nonacute cholecystitis (2.0%) (odds ratio = 5.172, P = .039). In patients with acute cholecystitis, indocyanine green did not change the rate of bail-out operation (indocyanine green: 12.7% vs no indocyanine green: 4.9%, P = .293).

CONCLUSION

This is the first series looking at the use of indocyanine green specifically in an acute care surgery population. Indocyanine green did not decrease operative time or need for a bail-out operation in acute cholecystitis. Further study is needed to determine whether indocyanine green use is justified in this population.
