Preoperative anticoagulation increases postoperative morbidity in bariatric patients

A recent analysis of 1,178,090 patients reveals that those undergoing sleeve gastrectomy or Roux-en-Y gastric bypass with preoperative therapeutic anticoagulation face significantly higher risks of postoperative complications. Specifically, these patients exhibited increased rates of anastomotic leaks, deep vein thrombosis, and gastrointestinal bleeding, as well as longer operative times and hospital stays. Moreover, sleeve gastrectomy patients had higher odds of adverse cardiovascular events, while those undergoing Roux-en-Y experienced more readmissions and unplanned ICU admissions.
