BACKGROUND 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. METHOD Sarcopenia was assessed in 763 patients(More)
BACKGROUND 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(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)
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)
BACKGROUND The impact of postoperative complications on the long-term outcomes of patients undergoing surgery for cancer is unclear. The objective of the current study was to define the incidence of complications among patients undergoing surgery for intrahepatic cholangiocarcinoma (ICC) and identify the association between morbidity and long-term outcomes.(More)
BACKGROUND Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract. Overall surgical experience with minimally invasive surgery (MIS) has increased; however, published reports on MIS resection of GIST are limited to small, single-institution experiences. METHODS A total of 397 patients who underwent open(More)
BACKGROUND The American College of Surgeons recently added liver-specific variables to the National Surgical Quality Improvement Program (NSQIP). We sought to use these variables to define patterns of care, as well as characterize perioperative outcomes among patients undergoing hepatic resection. METHODS The American College of Surgeons-NSQIP database(More)
IMPORTANCE Choledochal cysts (CCs) are rare, with risk of infection and cancer. OBJECTIVE To characterize the natural history, management, and long-term implications of CC disease. DESIGN, SETTING, AND PARTICIPANTS A total of 394 patients who underwent resection of a CC between January 1, 1972, and April 11, 2014, were identified from an international(More)
OBJECTIVE To characterize clinical and radiological features associated with biliary cystic tumors (BCTs) of the liver, and to define recurrence-free and overall survival. BACKGROUND Biliary cystadenoma (BCA) and biliary cystadenocarcinoma (BCAC) are rare tumors that arise in the liver. METHODS Between 1984 and 2013, 248 patients who underwent surgical(More)
OBJECTIVE This study was conducted to evaluate recurrence and survival among patients who underwent intraoperative margin re-resection for colorectal cancer liver metastases (CRLM). BACKGROUND Among patients who receive intraoperative margin re-resection, the relation between final margin status, pattern of recurrence, and survival is largely unknown. (More)
