The objective of this study was to determine the impact of caudate resection on margin status and outcomes during resection of extrahepatic hilar cholangiocarcinoma.A database of 1,092 patients treated for biliary malignancies at institutions of the Extrahepatic Biliary Malignancy Consortium was queried for individuals undergoing curative-intent resection for extrahepatic hilar cholangiocarcinoma...
Although gastrectomy with adequate regional nodal examination is considered the standard of care for invasive gastric adenocarcinoma, endoscopic resection has been adopted increasingly in select patients with T1 gastric cancer. The objective of this study was to identify preoperative predictors of lymph node metastasis in patients in the United States with T1 gastric cancer.Patients who underwent...
The impact of adjuvant chemotherapy and chemo-radiation therapy in the treatment of resectable gastric cancer remains varied. We sought to define the clinical impact of lymph node ratio on the relative benefit of adjuvant chemotherapy or chemo-radiation therapy among patients having undergone curative-intent resection for gastric cancer.Using the multi-institutional US Gastric Cancer Collaborative...
Most risk adjustment approaches adjust for patient comorbidities and the primary procedure. However, procedures done at the same time as the index case may increase operative risk and merit inclusion in adjustment models for fair hospital comparisons. Our objectives were to evaluate the impact of surgical complexity on postoperative outcomes and hospital comparisons in gastric cancer surgery.Patients...
Two important changes in the past decade have altered the landscape of graduate medical education (GME) in the U.S. The national restrictions on trainee duty hours mandated by the Accreditation Council for Graduate Medical Education (ACGME) were the most visible and generated much controversy. Equally important is the ACGME Outcome Project, which mandates competency-based training. Both of these changes...
Background. Cryosurgical ablation of malignant hepatic tumors is being increasingly used for definitive treatment of metastatic colorectal and primary hepatic tumors. The lack of tumor necrosis near vessels that results from inadequate freezing may contribute to local recurrence and thus limit the applications of this therapy. This study was designed to determine whether single-freeze cryoablation...
