BACKGROUND: Limited data exists regarding the impact of anesthesia residents on operating room efficiency and patient safety outcomes. This investigation hypothesized that supervised anesthesiology residents do not increase anesthesia-controlled or prolonged extubation times compared to supervised certified registered nurse anesthetists (CRNA)/certified anesthesiologist assistants (CAA) or anesthesiologists working independently. Secondary objectives included differences in critical outcomes such as intraoperative hypotension, cardiac and pulmonary complications, acute kidney injury, and mortality...

INTRODUCTION: Early after its adoption, minimally invasive surgery had limited usefulness in emergent cases. However, with improvements in equipment, techniques, and skills, laparoscopy in complex and emergency operations expanded substantially. This study aimed to examine the trend of laparoscopy in incarcerated or strangulated ventral hernia repair (VHR) over time. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for laparoscopic repair of incarcerated and strangulated hernias (LIS-VHR) and compared over 2 time periods, 2014-2016 and 2017-2019...

BACKGROUND: The benefits of prophylactic ureteral stent placement during colorectal surgery remain controversial. The aims of the present study were to determine the incidence of ureteral injury in colorectal operations, assess the complications associated with stent usage, and determine if their use leads to earlier identification and treatment of injury. METHODS: Retrospective study of patients undergoing colorectal abdominal operations between 2015 and 2021. Variables were examined for possible association with ureteral stent placement...

BACKGROUND: In most cases, a combination of paracetamol and ibuprofen are the optimal treatment for postoperative pain in third molar surgery. If stronger analgesia is required, opioids are traditionally administered. In day-case, surgery; however, opioids should be avoided. Thus, the anaesthetic agent S-ketamine in analgesic doses might be preferred. METHODS: The study was designed as a randomized placebo-controlled double-blind clinical trial. The study enrolled healthy subjects according to the American Society of Anaesthesiologists classification; I or II (ASA), aged 18 to 44 years, with a body weight between 50 and 100 kg...

(1) Background: Either pre-operative physical status or unstable hemodynamic changes has been reported to play a potential role in causing vital organ dysfunction. Therefore, we intended to investigate the impact of the American Society of Anesthesiologist (ASA) classification and intraoperative hemodynamic instability on non-surgical complications following orthopedic surgery. (2) Methods: We collected data on 6478 patients, with a mean age of 57.3 ± 16, who underwent orthopedic surgeries between 2018 and 2020...

BACKGROUND: The value of splenectomy for body localization (≥ 5 cm from spleen hilum) of pancreatic ductal adenocarcinoma (B-PDAC) is uncertain. This study assessed spleen-preserving distal pancreatectomy (SPDP) results for B-PDAC. PATIENTS AND METHODS: This single-center study included patients who underwent SPDP (Warshaw's technique) or distal splenopancreactomy (DSP) for B-PDAC from 2008 to 2019. Propensity score matching was performed to balance SPDP and DSP patients regarding sex, age, American Society of Anesthesiologists (ASA), body mass index (BMI), laparoscopy, pathological features [American Joint Committee on Cancer (AJCC)/tumor node metastasis classification (TNM)], margins, and neoadjuvant/adjuvant therapies...

OBJECTIVE: The study aimed at explore the correlation between the CT-based Peritoneal Carcinomatosis Index (PCI) and pathological parameters of rectal cancer, as well as the correlation with short-term postoperative prognosis. METHODS: A retrospective analysis was performed on 198 rectal cancer patients treated in our institution from January 2017 to December 2022. Based on preoperative CT-PCI, patients were classified into a normal and low CT-PCI groups. Baseline characteristics and short-term postoperative outcomes were compared between the two groups...

BACKGROUND: Treatment outcomes of incidental gallbladder cancer generally stem from tertiary referral centres, while many patients are initially diagnosed and managed in secondary care centres. Referral patterns of patients with incidental gallbladder cancer are poorly reported. This study aimed to evaluate incidental gallbladder cancer treatment in secondary centres, rates of referral to tertiary centres and its impact on survival. METHODS: Medical records of patients with incidental gallbladder cancer diagnosed between 2000 and 2019 in 27 Dutch secondary centres were retrospectively reviewed...

Background: Emergence delirium in children following strabismus surgery is a distressing and potentially dangerous condition and is likely attributable to visual disturbances, pain, and anesthetic gases. We explored whether a single intraoperative dose of methadone could reduce emergence delirium. Methods: Our study was an institutional review board-approved prospective, controlled, before-and-after investigation. Inclusion criteria were age <18 years and American Society of Anesthesiologists (ASA) classification 1 or 2...

BACKGROUND: Increasing life expectancy affects all aspects of healthcare. During surgery elderly patients are prone to complications and have higher risk of death. We aimed to investigate if adult patients undergoing surgery at a large Swedish university hospital were getting older and sicker over time, and if this potential shift in age and illness severity was associated with higher patient mortality rates. MATERIALS AND METHODS: This was a 16-year cohort study on all surgical procedures performed in adult patients 2006-2021 at two sites of X University Hospital...

INTRODUCTION: With the increasing incidence of total knee arthroplasty (TKA), there is an expected rise in rate of periprosthetic fractures in the coming years. It is unclear how the outcomes of patients with distal femur fractures (DFF) and a total knee arthroplasty compare to patients of the same age group with native knees (NK). MATERIALS AND METHODS: A retrospective review was completed for distal femur fractures treated with surgical fixation from January 2019-March 2021...

BACKGROUND: Currently, there is a lack of ideal risk prediction tools in the field of emergency general surgery (EGS). The American Association for the Surgery of Trauma recommends developing risk assessment tools specifically for EGS-related diseases. In this study, we sought to utilize machine learning (ML) algorithms to explore and develop a web-based calculator for predicting five perioperative risk events of eight common operations in EGS. METHOD: This study focused on patients with EGS and utilized electronic medical record systems to obtain data retrospectively from five centers in China...

PURPOSE: To compare dermal regenerative template (DRT), with and without split-thickness skin-grafting (STSG), and urinary bladder matrix (UBM) for coverage of lower extremity wounds. METHODS: A retrospective review of 56 lower extremity wounds treated with either DRT and STSG (DRT-S) (n = 18), DRT only (n = 17), or UBM only (n = 21). Patient characteristics, comorbidities, American Society of Anesthesiology (ASA) classification, injury characteristics, wound characteristics, use of negative pressure wound therapy, surgical details, postoperative care, and failure of primary wound coverage procedure were documented...

BACKGROUND AND AIMS: There is paucity of studies on preoperative risk assessment tools in patients undergoing emergency surgery. The present study evaluated the performance of the Acute Physiology and Chronic Health Evaluation (APACHE) II, American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) surgical risk calculator and American Society of Anesthesiologists (ASA) physical status (PS) classification system in patients undergoing emergency exploratory laparotomy...

BACKGROUND: Machine learning algorithms are finding increasing use in prediction of surgical outcomes in orthopedics. Random forest is one of such algorithms popular for its relative ease of application and high predictability. In the process of sample classification, algorithms also generate a list of variables most crucial in the sorting process. Total shoulder arthroplasty (TSA) is a common orthopedic procedure after which most patients are discharged home. The authors hypothesized that random forest algorithm would be able to determine most important variables in prediction of nonhome discharge...

INTRODUCTION: The Society for Vascular Surgery guidelines recommend annual imaging surveillance following endovascular aneurysm repair (EVAR) and every five years following open surgical repairs (OSR) of abdominal aortic aneurysms (AAA). Adherence to these guidelines is low outside of clinical trials and compliance at Veterans Affairs (VA) hospitals is not yet well established. We examined imaging follow-up compliance and mortality rates after AAA repair at VA hospitals. METHODS: We queried the VA Surgical Quality Improvement Program (VASQIP) database for elective infrarenal AAA repairs, EVAR and OSR, then merged in follow-up imaging and mortality information...

INTRODUCTION: The aging global population presents an increasing challenge for spine surgeons. Advancements in spine surgery, including minimally invasive techniques, have broadened treatment options, potentially benefiting older patients. This study aims to explore the clinical outcomes of spine surgery in septuagenarians and octogenarians. METHODS: This retrospective analysis, conducted at a US tertiary center, included patients aged 70 and older who underwent elective spine surgery for degenerative conditions...

PURPOSE: Rectal cancer and its treatment have a negative impact on health-related quality of life (HRQoL). If risk factors for sustained low HRQoL could be identified early, ideally before the start of treatment, individualised interventions could be identified and implemented to maintain or improve HRQoL. The study aimed to develop a multivariable prediction model for global HRQoL 12 months after rectal cancer treatment. METHODS: Within COLOR II, a randomised, multicentre, international trial of laparoscopic and open surgery for rectal cancer, a sub-study on HRQoL included 385 patients in 12 hospitals and five countries...

OBJECTIVE: Even low quantities of iodine contrast media (ICM) could be responsible for exacerbation of a chronic kidney disease (CKD). Aim of this study was to determine whether it is more reasonable to perform endovascular aneurysm repair (EVAR) procedures in patients with initial CKD using CO2 rather than ICM to prevent further kidney deterioration. METHODS: A retrospective analysis was performed at our institution to identify patients with preoperative CKD at initial stage (class G3a-G3b according to KDOQI-KDIGO classification) who underwent either CO2 -EVAR or ICM-EVAR...

Introduction: Distal radius fractures are a common injury of the hand and wrist that often require intensive rehabilitation. We sought to identify risk factors associated with discharge to a post-acute care facility following distal radius fracture repair. Methods: The 2011 to 2016 National Surgical Quality Improvement Program® (NSQIP) database was queried for all Current Procedural Terminology (CPT) codes that corresponded with open distal radius fracture repair. Patients with concomitant traumatic injuries were excluded...
