PD21-03 COSMETIC IMPACT OF PORT VERSUS PORTLESS NEEEDLESCOPIC SURGERY-A PROSPECTIVE, RANDOMIZED, SINGLE-BLINDED STUDY

2012 during which there was an intraoperative vascular, splenic or liver complication requiring the assistance of a second surgeon (i.e., a surgical crisis). Data was adjusted for clustering and weighting to achieve a nationally representative analysis. RESULTS: We evaluated a sample-weighted cohort of 841,002 procedures, of which 0.3%encountered a surgical crisis (0.4%open, 0.4% laparoscopic, 0.2% robotic). Patients undergoing robotic surgery had higher transfusion rates and lengths of stay when compared to laparoscopy, and similar to open surgery. While there was no difference between robotic and open surgeries in the full cohort (Table 1), a subset analysis of the healthiest patients (Charlson Comorbidity Index 0-1) showed an increased number of major complications for the robotic approach compared to the open approach (odds ratio: 4.59, p < 0.05, Figure 1). CONCLUSIONS: Surgical crises are rare, but our findings suggest that the robot may negatively impact the outcome of these events. Advances in emergency simulation and robotic technology could improve outcomes in robotic surgery when a catastrophic complication is encountered.
