Abstract
In recent years, fluorescent cholangiography using Indocyanine green (ICG) dye has been used to aid identification of structures during robotic cholecystectomy. We sought to compare cholecystectomy with ICG dye versus laparoscopic cholecystectomy at an inner-city academic medical center. Between January 2013 and July 2016, we identified 287 patients of which 191 patients underwent laparoscopic cholecystectomy and 96 patients underwent robotic cholecystectomy with ICG dye. Preoperative risk variables of interest included age, sex, race, body mass index (BMI), and acute cholecystitis. Primary outcome of interest was conversion to open procedures while secondary outcome was length of stay. The two groups were similar in their BMI (31.98 vs. 31.10 kg/m2 for the laparoscopic and robotic, respectively, p = 0.32). The laparoscopic group had a greater mean age compared to the robotic group (47.77 vs. 43.61 years, p = 0.04). There was no significant difference in sex and emergency surgery between the two groups. Fewer open conversions were found in the robotic than the laparoscopic group [2 (2.1%) vs. 17 (8.9%), p = 0.03]. In multiple logistic regression, robotic cholecystectomy with ICG also showed a lower risk of conversion compared to laparoscopic cholecystectomy, but the difference did not reach statistical significance (OR 0.42, 95% CI 0.11–1.65, p = 0.22). ICG fluorescent cholangiography during robotic cholecystectomy may contribute to proper identification of biliary structures and may reduce the rates of open conversion. The preliminary results of fewer open conversions are promising. Further studies with a large randomized prospective controlled study should be taken for further evaluation.
