BACKGROUND Intensive care unit (ICU) use has increased among patients with cancer. We sought to define factors associated with ICU admissions among patients with pancreatic cancer and characterize trends in mortality among hospital survivors. METHODS The Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database was used to identify patients with pancreatic cancer who underwent resection. Multivariable analyses were conducted to identify factors associated with ICU admission and...

Abstract null null Background null Regionalization of hepatopancreatic surgery to high-volume hospitals has been associated with fragmentation of postoperative care and, in turn, inferior outcomes after surgery. The objective of this study was to examine the association of social vulnerability with the likelihood of experiencing fragmentation of postoperative care (FPC) after hepatopancreatic surgery. null null null Methods null Patients who underwent hepatopancreatic surgery and had at least 1 ...

The use of composite measures like “textbook outcome” (TO) may provide a more accurate measure of surgical quality. We sought to determine if TO has improved over time and to characterize the association of achieving a TO with trends in survival among patients undergoing complex gastrointestinal surgery for cancer. Medicare beneficiaries who underwent pancreas, liver, or colon resection for a cancer diagnosis between 2004 and 2016 were identified using the SEER-Medicare database. Rates of TO (no...

OBJECTIVE The objective of the current study was to characterize the role of patient social vulnerability relative to hospital racial/ethnic integration on postoperative outcomes among patients undergoing pancreatectomy. BACKGROUND The interplay between patient- and community-level factors on outcomes after complex surgery has not been well-examined. METHODS Medicare beneficiaries who underwent a pancreatectomy between 2013 and 2017 were identified utilizing 100% Medicare inpatient files. P-SVI ...

Hepatocellular carcinoma (HCC) is the most commonly diagnosed primary liver tumor with an increasing incidence worldwide. Management of patients with HCC is largely dictated by the presence of cirrhosis, disease stage, underlying liver function, and patient performance status. We null provide an update on key aspects of surgical treatment options for patients with HCC. Liver resection and transplantation remain cornerstone treatment options for patients with early-stage disease and constitute th...

BACKGROUND Pancreatectomy is the main curative therapeutic option for pancreatic neuroendocrine tumors (pNETs). Given the indolent behavior of pNETs and the relatively limited lifetime of elderly patients, the impact of primary site surgery (PSS) of pNETs on long-term outcomes among older patients has been a topic of debate. METHODS Patients aged 70 or older with pNETs were identified in the Surveillance, Epidemiology and the End Results (SEER) database from 1998 to 2016. Propensity score matchi...

The effect of varying severity and timing of complications after hepatic resection on 30-day mortality has not been thoroughly examined. National Surgical Quality Improvement Program Patient User Files (NSQIP-PUF) were used to identify patients who underwent elective hepatic resection between 2014 and 2019. The impact of number, timing, and severity of complications on 30-day mortality was examined. Among 25,084 patients who underwent hepatic resection, 7436 (29.9%) patients developed at least o...

BACKGROUND The impact of tumor burden score (TBS) on conditional survival (CS) among patients undergoing curative-intent resection of hepatocellular carcinoma (HCC) has not been examined to date. METHODS Patients who underwent liver resection of HCC between 2000 and 2017 were identified from a multi-institutional database. The impact of TBS and other clinicopathologic factors on 3-year conditional survival (CS3) was examined. RESULTS Among 1,040 patients, 263 (25.3%) patients had low TBS, 668 (6...

Venous thromboembolism (VTE), including deep venous thrombosis (DVT) and pulmonary embolism (PE), represents a common cause of morbidity and mortality following complex gastrointestinal surgery. Whether perioperative VTE also exposes patients to a higher long-term risk of VTE events remains poorly defined. The Medicare 100% Standard Analytic Files were used to identify patients undergoing esophageal, hepatic, pancreatic, and colorectal resection between 2013 and 2017. The impact of perioperative...
