Abstract
PURPOSE: Tumor biopsy is often essential for diagnosis and management of intraabdominal neoplasms found in children. Open surgical biopsy is the traditional approach used to obtain an adequate tissue sample to guide further therapy, but image-guided percutaneous core-needle biopsy is being used more often due to concerns about the morbidity of open biopsy. We used a national database to evaluate the morbidity associated with open intraabdominal tumor biopsy. METHODS: We identified all patients undergoing laparotomy with tumor biopsy in the National Surgical Quality Improvement Project-Pediatric (NSQIP-P) database from 2012 to 2018 and measured the frequency of complications in the 30 days postoperatively. We tested associations between patient characteristics and outcomes to identify risk factors for complications. RESULTS: We identified 454 patients undergoing laparotomy for biopsy of an intraabdominal neoplasm. Median postoperative hospital stay was 7 days (IQR 4-12) and operative time was 117 min (IQR 84-172). The overall complication rate was 12.1%, with post-operative infection (6%) and bleeding (4.2%) being the most common complications. Several patient characteristics were associated with bleeding, but the only significant association on multivariable analysis was underlying hematologic disorder. CONCLUSION: Open abdominal surgery for pediatric intraabdominal tumor biopsy is accompanied by significant morbidity. Postoperative infection was the most common complication, which can delay initiation of further therapy, especially chemotherapy. These findings support the need to prospectively compare percutaneous image-guided core-needle biopsy to open biopsy as a way to minimize risk and optimize outcomes for this vulnerable population.
