Importance: Despite improvements in perioperative mortality, the incidence of postoperative surgical site infection (SSI) remains high after pancreatoduodenectomy. The effect of broad-spectrum antimicrobial surgical prophylaxis in reducing SSI is poorly understood.
Objective: To define the effect of broad-spectrum perioperative antimicrobial prophylaxis on postoperative SSI incidence compared with standard care antibiotics.
Objective: To (1) evaluate rates of surgery for clinical stage I-II pancreatic ductal adenocarcinoma (PDAC), (2) identify predictors of not undergoing surgery, (3) quantify the degree to which patient- and hospital-level factors explain differences in hospital surgery rates, and (4) evaluate the association between adjusted hospital-specific surgery rates and overall survival (OS) of patients treated at different hospitals.
Background: Curative-intent surgery for potentially resectable PDAC is underutilized in the United States.
Methods: Retrospective cohort study of patients ≤85 years with clinical stage I-II PDAC in the 2004 to 2014 National Cancer Database.
Objectives/hypothesis: 1) Identify the major expenses for outpatient pediatric tympanostomy tube placement in a multihospital network. 2) Compare differences for variations in costs among hospitals and surgeons.
Methods: An observational cohort study in a multihospital network using a standardized activity-based accounting system to determine hospital costs for tympanostomy tube placement from February 2011 to January 2015.
Background: Enhanced recovery after colon surgery has not been widely adopted in the United States and Europe, despite evidence that postoperative complications and hospital length of stay are decreased.
Objective: We sought to evaluate the introduction of a comprehensive care process for enhanced recovery after colon surgery in 8 community hospitals.
Design: A system-wide, surgeon-directed, multidisciplinary committee developed a comprehensive enhanced-care quality-improvement program.
Background: Soft tissue sarcomas generally have a
Methods: 29 patients with nonmetastatic synovial, epithelioid, and clear cell sarcomas who underwent SLNB were examined.
Background: Optimal management of patients with hepatocellular carcinoma (HCC) is controversial. This study was conducted to evaluate the outcome of tumor resection versus assignment to a liver transplant waiting list (WL) in patients with HCC.
Methods: Prospectively collected patient data from 1970 to 1997 on 313 patients with HCC were retrospectively analyzed by multivariate analysis to determine the effect of liver disease, method of treatment, and tumor-related factors on survival.
Background: Extramammary Paget's disease (EMPD) is a rare clinical entity and can be associated with other malignancies. We analyzed our experience for prognosis and impact of therapy on outcomes.
Study Design: We conducted a retrospective review of all patients (n = 33) with EMPD treated at a tertiary care center from 1971 to 1998.
Background And Objectives: Extremity myxoid liposarcomas have a unique extrapulmonary metastatic potential. We studied the metastatic pattern of extremity liposarcomas to determine what types of posttreatment imaging may be of value in the follow-up these patients.
Methods: Twenty-two patients from a total of 128 patients with primary extremity liposarcoma were treated at a tertiary care institution for subsequent metastases from January 1981 to January 2000.
Background: Anaplastic thyroid carcinoma (ATC) is an aggressive rare tumor. We analyzed our experience for prognosis and the effect of surgery and radiotherapy on patients with ATC.
Methods: We conducted a retrospective review of all patients (n = 67) with ATC treated at a tertiary care center from 1969 to 1999.
