Multicenter Study
Postoperative complications reduce adjuvant chemotherapy use in resectable pancreatic cancer.
To assess the impact of postoperative complications on the receipt of adjuvant chemotherapy. ⋯ Postoperative complications are common following pancreatic surgery and are associated with adjuvant chemotherapy omission and treatment delays.

Randomized Controlled Trial Multicenter Study
Endoscopic harvesting device type and outcomes in patients undergoing coronary artery bypass surgery.
To evaluate angiographic and clinical outcomes associated with open and closed dissection tunnel endoscopic vein harvesting (EVH) devices. ⋯ No differences in angiographic or clinical outcomes were observed among patients who underwent open versus closed tunnel endoscopic harvesting for coronary bypass surgery. These findings suggest that the risks associated with EVH that were reported in a previous PREVENT-IV analysis are not related to a specific EVH device.

To assess the risk of bias in multicenter randomized controlled trials (RCTs) investigating laparoscopic colorectal cancer surgery and review the use of quality assurance mechanisms to reduce performance bias. ⋯ Consideration of risk of performance bias is important when appraising trials investigating an interventional technique. Laparoscopic colorectal surgery RCTs have all employed quality assurance mechanisms to reduce risk of performance bias. Further research is indicated to investigate adopting objective assessment tools for quality assurance within multicenter RCTs.

The objectives of this study were to assess the applicability of patents and publications as metrics of surgical technology and innovation; evaluate the historical relationship between patents and publications; develop a methodology that can be used to determine the rate of innovation growth in any given health care technology. ⋯ This article demonstrates the utility of publically available patent and publication data to quantify innovations within surgical technology and proposes a novel methodology for assessing and forecasting areas of technological innovation.

Multicenter Study
Predicting recurrence of pancreatic solid pseudopapillary tumors after surgical resection: a multicenter analysis in Korea.
Solid pseudopapillary tumors (SPTs) of the pancreas are still considered a surgical enigma. Many clinical research trials have failed to identify prognostic factors that predict the malignant behavior of SPTs. ⋯ More specific pathologic descriptions need to be employed in pathologic report forms to provide proper information to predict SPT recurrence after resection. Future studies emphasizing the standardized pathologic evaluation of pancreatic SPTs may unveil the enigmatic nature of pancreatic SPTs.
