Surgery (General)

PURPOSE: It is unclear whether the Geriatric-8 (G8) has the accuracy to preselect patients for complete geriatric assessment, and has the ability to predict adverse outcomes in patients with colorectal cancer (CRC). We therefore aimed to determine whether the G8, or other variables present in the medical record, are applicable in predicting 30-day adverse outcomes in older patients undergoing surgery for CRC. METHODS: We performed a retrospective cohort study involving patients ≥70 years who had surgery for CRC between 2018 and 2020 in a general hospital in the Netherlands...

The Centers for Medicare & Medicaid Services is continually working to mitigate unnecessary expenditures, particularly in post-acute care (PAC). Medicare reimburses for orthopaedic surgeon services in varied models, including fee-for-service, bundled payments, and merit-based incentive payment systems. The goal of these models is to improve the quality of care, reduce health-care costs, and encourage providers to adopt innovative and efficient health-care practices. This article delves into the implications of each payment model for the field of orthopaedic surgery, highlighting their unique features, incentives, and potential impact in the PAC setting...

OBJECTIVE: Determine the proportion of contemporary US academic general surgery residency program graduates who pursue academic careers and identify factors associated with pursuing academic careers. SUMMARY BACKGROUND DATA: Many academic residency programs aim to cultivate academic surgeons, yet the proportion of contemporary graduates who choose academic careers is unclear. The potential determinants that affect graduates' decisions to pursue academic careers remain underexplored...

Laparoscopic Roux-en-Y gastric bypass (RYGB) is crucial for significant weight reduction and treating obesity-related issues. However, the impact of gastrojejunostomy (GJ) anastomosis diameter on weight loss remains unclear. We investigate this influence on post-RYGB weight loss outcomes. A systematic search was conducted. Six studies met the inclusion criteria, showing varied GJ diameters and follow-up durations (1-5 years). Smaller GJ diameters generally correlated with greater short-to-medium-term weight loss, with a threshold beyond which complications like stenosis increased...

A retrospective cohort study of patients undergoing laparoscopic inguinal hernia repair compared short- and long-term outcomes between individuals with or without history of previous abdominopelvic surgery, aiming to determine the feasibility of totally extraperitoneal (TEP) repair within this population. All patients who underwent elective TEP inguinal hernia repair by one consultant surgeon across three London hospitals from January 2017 to May 2023 were retrospectively analysed to assess perioperative outcomes...

INTRODUCTION: Prophylactic meshes in high-risk patients prevent incisional hernias, although there are still some concerns about the best layer to place them in, the type of fixation, the mesh material, the significance of the level of contamination, and surgical complications. We aimed to provide answers to these questions and information about how the implanted material behaves based on its visibility under magnetic resonance imaging (MRI). METHOD: This is a prospective multicentre observational cohort study...

BACKGROUND: The objective of this study is to examine the application of AI algorithms in detecting OPMD and oral cancerous lesions, and to evaluate the accuracy variations among different imaging tools employed in these diagnostic processes. MATERIALS AND METHODS: A systematic search was conducted in four databases: Embase, Web of Science, PubMed, and Scopus. The inclusion criteria included studies using machine learning algorithms to provide diagnostic information on specific oral lesions, prospective or retrospective design, and inclusion of OPMD...

PURPOSE: This study investigated the prognostic value of the geriatric nutritional risk index (GNRI) in patients undergoing curative gastrectomy for remnant gastric cancer (RGC). METHODS: This multicenter retrospective study included 105 patients with RGC of ≥ 65 years of age who underwent curative gastrectomy at 10 institutions in Japan between January 2000 and December 2016. Postoperative complications, overall survival (OS), and disease-specific survival (DSS) were analyzed...

PURPOSE: Office-based rhinologic procedures (OBRP) have become widely available in North America due to technological advances and appropriate patient selection. Nevertheless, the literature exploring the safety of these procedures remains limited. The objective of this study was to further evaluate the safety, tolerability and efficacy of these procedures with a more robust sample size to allow for capture of rare events. METHODS: A retrospective chart review of all patients who underwent OBRP from May 2015 to March 2023...

BACKGROUND: The aim of this study was to evaluate the effectiveness of a modified reconstruction technique-anchored straight stomach reconstruction-in reducing the incidence of delayed gastric emptying (DGE) after pancreaticoduodenectomy (PD) and its impact on postoperative nutritional recovery. METHODS: A case series analysis of 125 consecutive PD patients was conducted: 104 of them had undergone anchored straight stomach reconstruction (SSR group) and the remaining 21 without (Non-SSR group)...

PURPOSE: The proximal radio-ulnar joint allows supination and pronation of the forearm and the humeroradial joint allows flexion and extension movements at the elbow joint. Although the proximal end of the radius is less common than other fractures, it is more common nowadays due to the prolongation of life expectancy, increased incidence of osteoporosis. There have been reports in the literature that success has not been achieved due to the lack of anatomical fit of the prosthesis. Knowledge of the morphometric features of the proximal end of the radius is important for the design of anatomically and biomechanically appropriate prostheses...

PURPOSE: By selectively perfusing the first three jejunal arteries (JA), we aim to assess the individual perfusion length of small bowel (SB) and its impact on nodal resection in stage III-up small-intestinal neuroendocrine tumors (SI-NET). METHODS: Our anatomical research protocol implies a midline laparotomy and three measures of the SB length. We then perform a classical anterior approach of the superior mesenteric vessels. We carry on with the complete dissection and checking of the superior mesenteric artery (SMA) in order to identify the first three JA...

The superior thyroid cornu (STC) is a normal anatomic structure that forms part of the thyroid cartilage. Here, we report a patient with unusually elongated and ossified STC that might result in recurrent cerebral embolisms. During a second endovascular therapy for recurrent middle cerebral artery embolism, a segment with an irregular filling defect was noted in the internal carotid artery (ICA), at the C1 level. This defect was unnoticed during the initial endovascular procedure. Three-dimensional computed tomography angiography performed after the second endovascular procedure revealed an ICA segment located between the STC and C1 with a tortuous course and irregular wall of the ICA...

PURPOSE: In the present study, we want to systematize the previous studies on the scapular foramina (SF) and nutrient foramina (NF) with emphasis on the clinical relevance of this topic. Although seemingly not important, radiologists, clinicians and surgeons should be aware of the presence and characteristics of the SF and NF and look out for possible mistakes that may cause harm to the patients during either the diagnostic process or surgery. METHODS: A comprehensive search was conducted in multiple databases, including PubMed, Scopus, Web of Science, Embase, Cochrane Library and Google Scholar...

PURPOSE: This study aimed to investigate the distance and correlation between the anatomy of the anterior side of the hip joint and the femoral nerve. METHODS: Using ten fresh-frozen cadavers with twenty hip joints. We dissected and marked the femoral nerve in the inguinal area. Employing the direct anterior approach, we identified and marked study points, including the superior and inferior points of the anterior rim of the acetabulum, ¼ point, half point, and ¾ point along an imagined line connecting the formers, the inferomedial and mid aspect of the femoral neck, and the soft spot...

PURPOSE: The hamstrings muscles are innervated by sciatic nerve branches. However, previous studies assessing which and how many branches innervate each muscle have yielded discrepant results. This study investigated the innervation patterns of hamstrings. MATERIALS AND METHODS: Thirty-five cadaver limbs were investigated. The average age of subjects was 78.6 ± 17.2 years, with 48.6% male and 51.4% female, while 57.1% were right limbs and 42.9% left...

Anatomical variations are a common feature of the human anatomy. Variation can explain some pathological conditions and is important to keep them in mind during surgical procedures. The relations between nerves and their adjacent arteries have been proposed to play a role in the generation of peripheral trigger migraines. Close opposition between nerves and arteries can lead to vascular compression of the nerve that triggers episodes of pain. We did a routine dissection of the infratemporal fossa and orbital floor by opening the maxillary sinus...
