About
Zachary E. Stiles is a surgical researcher whose work sits at the intersection of minimally invasive surgery and complex abdominal oncology, with a particular focus on hepatopancreatic and gastrointestinal procedures. His most influential contributions center on understanding the phenomenon of unplanned surgical conversion — the unanticipated shift from minimally invasive to open operative approaches — and its consequences for patient outcomes. Drawing on large national datasets such as the ACS-NSQIP database, Stiles has brought rigorous, population-level evidence to bear on questions that directly inform surgical decision-making and preoperative risk stratification. His 2017 analysis of unplanned conversion during minimally invasive hepatectomy, accumulating 45 citations, established key predictors and clinical implications that have shaped how surgeons approach patient selection. His complementary 2018 study on minimally invasive pancreatectomy, cited 39 times, extended this work to one of the most technically demanding operations in abdominal surgery. More recently, Stiles has expanded his scope to include pancreatic adenocarcinoma and gastroesophageal junction tumors, reflecting a broadening interest in oncologic surgical strategy. Collectively, his research offers surgeons evidence-based guidance for minimizing risk and optimizing outcomes in high-stakes minimally invasive procedures.
