We thank Drs Conway and Gagandeep for their comments. We agree that the EBL is less accurate than one might wish, and in our review of the University of California–Los Angeles experience with resection for pancreatic cancer, the recorded EBL value was that of the anesthesiologist’s, taken from the operative record. Because our report is a retrospective case series, the suggestion that EBL values were biased because they were being used as a performance indicator or end point is incorrect. The anesthesiologists (none of whom were coauthors of the article) “called it as they saw it” during the entire study period, and the data speak for themselves.
