Purpose: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) surgical risk calculator is a risk stratification tool to help predict risks of postoperative complications, which is important for informed decision-making. The purpose of this study was to evaluate the accuracy of the calculator in predicting postoperative complications in patients undergoing common bile duct (CBD) exploration.
Methods: A retrospective chart review was completed for 305 patients that underwent open and laparoscopic CBD exploration at a single institution from 2010 to 2018.
Background: The aim of this study was to assess the utility of laparoscopic ultrasound (LUS) during minimally invasive liver procedures in patients with malignant liver tumors who underwent preoperative magnetic resonance imaging (MRI).
Methods: Medical records of patients with malignant liver lesions who underwent laparoscopic liver surgery between October 2005 and January 2018 and who underwent an MRI examination at our institution within a month before surgery were collected from a prospectively maintained database. The size and location of tumors detected on LUS, as well as whether they were seen on preoperative imaging, were recorded.
Background: Fine needle aspiration (FNA) biopsy is an essential procedure for thyroid nodules. Although, the efficacy of surgeon-performed thyroid FNA biopsies has been demonstrated in the literature, there are insufficient data regarding how to establish an efficient program with a low insufficiency rate within a group practice.
Methods: An endocrine surgery thyroid FNA biopsy program was established in 2000 by one surgeon, with training of additional partners during fellowship and upon recruitment.
Background: Recent studies have reported the feasibility of indocyanine green fluorescence imaging of adrenal tumors to guide dissection. Although the adrenal has been reported to concentrate the dye more than surrounding tissues, the amount of tissue distinction and how this compares with conventional vision has not been quantified before. The aim of this study is to quantify this distinction using color analysis.

Materials And Methods: 32 rats were randomly divided into four groups: control group (L): laparotomy, sham group: splenectomy (S), splenectomy group treated with curcumin (SC) and splenectomy group treated with corn oil (SCO) for 28 days. The primary outcomes; total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), oxidized LDL (ox-LDL) very-low-density lipoprotein (VLDL) and lectin-type oxidized LDL receptor 1 (LOX-1), secondary outcomes: nuclear factor kappa B (NF-кB), malondialdehyde (MDA), glutathione peroxidase (GPx), superoxide dismutase (SOD) were measured.
Aim: The aim was to investigate the RAS discordance between initial and recurrent metastasectomy specimens in metastatic colorectal cancer (mCRC) patients treated with chemotherapy (CT) plus biological agents in a first-line setting.
Methods: Patients who had been treated with CT plus bevacizumab or cetuximab or panitumumab followed by R0 resection for potentially resectable colorectal cancer liver metastases were scanned. Among these, patients who developed resectable new metastases after a disease-free interval longer than 6 months were included in the study.
Objective: The aim of this study was to analyze the incidence of and risk factors for adrenocortical carcinoma (ACC) in adrenal incidentaloma (AI).
Summary Of Background Data: AI guidelines are based on data obtained with old-generation imaging and predominantly use tumor size to stratify risk for ACC. There is a need to analyze the incidence and risk factors from a contemporary series.
New imaging techniques using near-infrared (NIR) fluorescence in combination with remote access thyroidectomy have been studied in endocrine surgery to determine their utility, with the goal of reducing potential complications. Indocyanine green (ICG) imaging is a safe adjunct to remote access thyroid surgery. Nevertheless, experience with ICG is limited, and the caveats surrounding the use of ICG imaging in conventional thyroid surgery exist in remote access surgery as well.

Methods: This is an IRB-approved prospective study.
Background: The aim of this study was to determine both the accuracy of near infrared fluorescence imaging to detect parathyroid glands and the potential indications of near infrared fluorescence imaging in thyroid and parathyroid surgery by correlating the autofluorescence signature with the pathologic specimen.
Methods: This was an institutional review board-approved, prospective study of patients undergoing thyroidectomy and parathyroidectomy with near infrared fluorescence imaging. Each specimen sent to pathology was inspected with near infrared fluorescence imaging and predicted to be either parathyroid or non-parathyroid tissue by its autofluorescence signature and then correlated with the pathologic findings.
Introduction: Although frequently used as an adjunct to cytology in patients with differentiated thyroid cancers, interpretation of thyroglobulin washout remains unclear. We aim to compare the utility of different analytic tools to develop recommendations for use in post-total thyroidectomy follow-up.
Methods: This is an institutional review board-approved retrospective study of patients who underwent lymph node fine needle aspiration biopsy with thyroglobulin washout between 2012 and 2018, during the post-total thyroidectomy follow-up of differentiated thyroid cancer.
Background: Laparoscopic liver resection (LLR) of posterosuperior (PS) segment liver tumors is technically challenging with confusion about optimal patient positioning and trocar placement (i.e., transabdominal vs.

Over the years, we have been treating selected patients with neuroendocrine liver metastases (NELM) with laparoscopic ablation (LA) and reported favorable local tumor control. The aim of this study is to see whether this local efficacy translates into long-term oncologic outcomes.

Background: Clinical scoring systems have been used to reduce negative appendectomy rate for several decades. However, the use of these systems has been questioned due to differences in their diagnostic accuracies. The aim of this prospective study was to develop a new clinical scoring system using a combination of all previously described variables for the diagnosis of acute appendicitis (AA).
View Article and Find Full Text PDFBackground: Although parathyroid glands have been found to exhibit autofluorescence with near-infrared fluorescence imaging, it is unknown if autofluorescence characteristics vary between hyperfunctioning and normofunctioning glands. The hypothesis was that pattern of autofluorescence exhibited by hyperfunctioning versus normofunctioning parathyroid glands would be different.
Methods: This is an Institutional Review Board-approved, prospective clinical study.
Introduction: The aim of this report was to perform a cost-comparison between liver resection (LR) and radiofrequency ablation (RFA).
