While sarcopenia is typically defined using total psoas area (TPA), characterizing sarcopenia using only a single axial cross-sectional image may be inadequate. We sought to evaluate total psoas volume (TPV) as a new tool to define sarcopenia and compare patient outcomes relative to TPA and TPV. Sarcopenia was assessed in 763 patients who underwent(More)
The use of minimally invasive surgery (MIS) for choledochal cyst (CC) has not been well documented. We sought to define the overall utilization and outcomes associated with the use of the open versus MIS approach for CC. We examined the factors associated with receipt of MIS for CC, as well as characterized perioperative and long-term outcomes following(More)
This study was conducted to evaluate recurrence and survival among patients who underwent intraoperative margin re-resection for colorectal cancer liver metastases (CRLM). Among patients who receive intraoperative margin re-resection, the relation between final margin status, pattern of recurrence, and survival is largely unknown. Three hundred thirty-two(More)
Surgical experience with minimally invasive surgery (MIS) has increased; however, published reports on MIS resection of gastric adenocarcinoma are limited. Between 2000 and 2012, 880 patients who underwent surgical resection of gastric adenocarcinoma were identified from a multi-institutional database. Clinicopathological characteristics, operative details,(More)
BACKGROUND Endoscopic ultrasound (EUS) can be used to guide the therapeutic plan for patients with gastric adenocarcinoma (GAC), but data on its use and accuracy remain poorly defined. We sought to define the use of EUS, as well as characterize the diagnostic accuracy of EUS among patients with GAC. STUDY DESIGN We identified 960 patients who underwent(More)
IMPORTANCE Whereas conventional actuarial overall survival (OS) estimates rely exclusively on static factors determined around the time of surgery, conditional survival (CS) estimates take into account the years that a patient has already survived. OBJECTIVE To define the CS of patients following liver resection for intrahepatic cholangiocarcinoma (ICC).(More)
The incidence of venous thromboembolism (VTE) among patients undergoing hepatic surgery is poorly defined, leading to varied use of VTE prophylaxis among surgeons. We sought to define the incidence of VTE after liver surgery and identify risk factors associated with VTE. Incidence of VTE and associated risk factors within 90 days of hepatic resection(More)
The significance of indeterminate pulmonary nodules (IPNs) in patients undergoing resection of pancreatic ductal adenocarcinoma (PDAC) is unknown. We sought to define the prevalence and impact of IPN in such patients. We studied all patients who underwent surgical resection of PDAC between 1980 and 2013. IPN was defined as ≥1 well-defined lung nodule(s)(More)
Owing to striking features of numerous multinucleated cells and bone destruction, giant cell tumor (GCT) of bone, often called as osteoclastoma, has drawn major attractions from orthopaedic surgeons, pathologists, and radiologists. The name GCT or osteoclastoma gives a false impression of a tumor comprising of proliferating osteoclasts or osteoclast(More)
BACKGROUND While traditional survival analyses focus on factors determined at the time of surgery, conditional survival (CS) estimates prognosis relative to time following treatment. We sought to compare actuarial and CS among patients undergoing curative intent surgery for hilar cholangiocarcinoma. METHODS 242 patients undergoing surgery between 2000 and(More)
