Following propensity matching, there were no differences in baseline characteristics between patients who underwent ESG with a gastroenterologist or bariatric surgeon. There was no difference in AE in ESG performed by either specialty (p .0.05). ESG performed by bariatric surgeons led to a higher rate of reoperations within 30 days (p50.025). ESG performed by gastroenterologists led to more ER visits but did not lead to a higher rate of readmissions or reinterventions. LOS was shorter in ESG performed by gastroenterologists, whereas procedure time was longer. Conclusion: ESG is safely performed by both gastroenterologists and bariatric surgeons. Patients who underwent ESG with a gastroenterologist visited the ER more often, while bariatric surgeons were more likely to re-operate on patients within 30d-perhaps highlighting variations in technique or postprocedural management. Both specialties should continue collaborating to expand access while standardizing procedural technique and competency requirements (Table ).[1081] Figure 1. Sample locations: 1) The elevator tab, 2) instrument channel distal opening, 3) composite duodenoscope tip, and 4) the instrument channel. Samples 1-3 were collected with flocked swabs. The 4th was collected by flushing 25 mL of neutralizing buffer through the instrument channel, then scrubbing the channel with a brush, followed by another 25mL flush. The 50mL eluent was vacuum filtered through a 0.22-micron filter and plated on TSA. Duodenoscope serial numbers were recorded and one duodenoscope grew VRE in Phase 1 and Phase 2.
