Accurate differentiation of pancreatic cystic lesions is important for pancreatic cancer early detection and prevention as well as avoidance of unnecessary surgical intervention. Serous cystic neoplasms (SCN) have no malignant potential, but may mimic premalignant mucinous cystic lesions: mucinous cystic neoplasm (MCN) and intraductal papillary mucinous neoplasm (IPMN). We recently identified vascular endothelial growth factor (VEGF)-A as a novel pancreatic fluid biomarker for SCN. We hypothesize that combining cyst fluid carcinoembryonic antigen (CEA) with VEGF-A will improve the diagnostic accuracy of VEGF-A. ⋯ Although VEGF-A alone is a highly accurate test for SCN, the combination of VEGF-A with CEA approaches the gold-standard of pathologic diagnosis, thus importantly avoiding false positives. Patients with a positive test indicating benign SCN can be spared a high risk surgical pancreatic resection.

Comparative Study
Onlay with Adhesive Use Compared to Sublay Mesh Placement in Ventral Hernia Repair: Was Chevrel Right? An Americas Hernia Society Quality Collaborative Analysis.
The use of mesh during ventral hernia repair (VHR) is a well-accepted concept. However, the ideal location of mesh placement remains strongly debated. Although VHR with onlay mesh placement has historically been associated with a high rate of wound events, this surgical approach is technically less challenging than VHR with sublay mesh placement. The purpose of this study was to compare 30-day wound events after onlay mesh placement with adhesive fixation vs those after sublay mesh placement using the Americas Hernia Society Quality Collaborative database. ⋯ Ventral hernia repair with onlay mesh placement is a safe alternative to VHR with sublay mesh placement in low-risk patients. Additional studies are needed to determine the long-term mesh outcomes and recurrence rates in both of these groups.

With increasing Medicaid coverage, it has become especially important to determine whether racial differences exist within the Medicaid system. We asked whether disparities exist in hospital practice and patient outcomes between matched black and white Medicaid children with chronic conditions undergoing surgery. ⋯ We did not observe disparities in 30-day revisits and readmissions for chronically ill children in Medicaid undergoing surgery, and only slight differences in length of stay, ICU length of stay, and use of the ICU, where blacks displayed somewhat elevated rates compared with white controls.

The incidence of histopathologic organ invasion (HOI) in retroperitoneal sarcoma (RPS) is not well described. We reviewed our experience to investigate the rate and prognostic implications of HOI. ⋯ The likelihood of organ invasion can be predicted by histologic subtype of primary RPS. To the best of our knowledge, this is the first study to demonstrate that HOI is associated with worse overall survival. These data can help guide the minimal extent of surgical resection required for RPS.

Transsphenoidal surgery is a common neurosurgical procedure for accessing the pituitary and anterior skull base, yet few multicenter analyses have evaluated outcomes after this procedure. ⋯ Overall rates of adverse events in patients undergoing transsphenoidal surgery are relatively low, and most occur before discharge from the hospital. Post-discharge complications associated with transsphenoidal surgery include deep vein thrombosis, pulmonary embolism, and urinary tract infection. Delayed postoperative cerebrospinal fluid leak is the major cause of reoperation, and hyponatremia is the major cause of readmission.
