Central versus posterior approach

PURPOSE: Esophagectomy is the primary surgical treatment for esophageal cancer, although other treatment approaches are often incorporated, including preoperative chemotherapy and chemoradiotherapy. The two major routes of esophageal reconstruction after esophagectomy are the anterior mediastinal (retrosternal, heterotopic) and posterior mediastinal (prevertebral, orthotopic) routes. However, which of these two routes of reconstruction is the most appropriate remains controversial. This systematic review aimed to compare the efficacy and safety of anterior mediastinal reconstruction with those of posterior mediastinal reconstruction after esophagectomy in esophageal cancer...

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: The purpose of this study is to compare the impact of anterior cervical decompression and fusion (ACDF) versus posterior cervical decompression and fusion (PCDF) for the treatment of acute traumatic central cord syndrome (CCS) on hospital episodes of care in terms of (1) cost, (2) length of hospital stay, and (3) discharge destination. SUMMARY OF BACKGROUND DATA: Acute traumatic CCS is the most common form of spinal cord injury in the United States...

PURPOSE: To explore the central and peripheral retinal and choroidal changes in retinal vein occlusion (RVO) and fellow eyes using ultra-widefield swept-source optical coherence tomography angiography (UWF-SS-OCTA). METHODS: Fifteen ischemic central RVO (CRVO), 15 branch RVO (BRVO), and 15 age-matched healthy controls were prospectively recruited. Retinal and choroidal parameters, including retinal vessel flow density (VFD) and vessel linear density (VLD), choroidal vascularity volume (CVV), choroidal vascularity index (CVI), and VFD in the large and medium choroidal vessels (LMCV-VFD), were measured in the central and peripheral regions of the 24 × 20-mm UWF-SS-OCTA images...

BACKGROUND: Triamcinolone acetonide (TA) is administered as an intravitreal or posterior sub-Tenon's capsule injection, as treatment for diabetic macular edema (DME). The intravitreal use of TA is limited because commercially available triamcinolone acetonide contains benzyl alcohol, a neurotoxic preservative. Few studies have compared effects of preservative-free intravitreal TA (IVTA) and posterior sub-Tenon capsule TA (STTA) injections for DME. Thus, herein, we compared the effectiveness of preservative-free IVTA and STTA for treatment of bevacizumab-resistant DME...

BACKGROUND: The aim of this study is to conduct a comparative evaluation of different designs of clear aligners and examine the disparities between clear aligners and fixed appliances. METHODS: 3D digital models were created, consisting of a maxillary dentition without first premolars, maxilla, periodontal ligaments, attachments, micro-implant, 3D printed lingual retractor, brackets, archwire and clear aligner. The study involved the creation of five design models for clear aligner maxillary anterior internal retraction and one design model for fixed appliance maxillary anterior internal retraction, which were subsequently subjected to finite element analysis...

Except when surgery is the only option because of organ damage, the presence of suspicious lesions, or the desire to conceive, women with endometriosis-associated pain often face a choice between medical and surgical treatment. In theory, the description of the potential benefits and potential harms of the two alternatives should be standardized, unbiased, and based on strong evidence, enabling the patient to make an informed decision. However, doctor's opinion, intellectual competing interests, local availability of specific services and (mis)information obtained from social media, and online support groups can influence the type of advice given and affect patients' choices...

Historically, children afflicted with long gap esophageal atresia (LGEA) had few options, either esophageal replacement or a life of gastrostomy feeds. In 1997, John Foker from Minnesota revolutionized the treatment of LGEA. His new procedure focused on "traction-induced growth" when the proximal and distal esophageal segments were too far apart for primary repair. Foker's approach involved placement of pledgeted sutures on both esophageal pouches connected to an externalized traction system which could be serially tightened, allowing for tension-induced esophageal growth and a delayed primary repair...

OBJECTIVE: To gain new insight into the molecular changes of the meniscus by comparing the proteome profiles of healthy controls with mild degeneration and end-stage osteoarthritis (OA). METHOD: We obtained tissue plugs from lateral and medial menisci of 37 individuals (central part of the posterior horn) classified as healthy (n ​= ​12), mild signs of joint damage (n ​= ​13) and end-stage OA (n ​= ​12)...

Knee osteoarthritis (OA), a prevalent joint disease in the U.S., poses challenges in terms of predicting of its early progression. Although high-resolution knee magnetic resonance imaging (MRI) facilitates more precise OA diagnosis, the heterogeneous and multifactorial aspects of OA pathology remain significant obstacles for prognosis. MRI-based scoring systems, while standardizing OA assessment, are both time-consuming and labor-intensive. Current AI technologies facilitate knee OA risk scoring and progression prediction, but these often focus on the symptomatic phase of OA, bypassing initial-stage OA prediction...

OBJECTIVE: To compare the efficacy of rotator interval (RI) versus posterior approach (PA) ultrasound (US) guided corticosteroid injections into the glenohumeral (GH) joint in primary frozen shoulder (PFS). DATA SOURCES: A systematic literature search for all relevant studies on Medline, Scopus, Embase, Web of Science and Cochrane Central, up to January 2023 was conducted. STUDY SELECTION: Randomized clinical trials that directly compared the US-guided corticosteroid injection into the RI and GH joint using PA in patients clinically and radiographically diagnosed with PFS...

The endovascular treatment of posterior circulation aneurysms, although challenging, has been well-established due to various factors that limit the surgical approach in most cases. Flow diversion has also been utilized in the treatment of such aneurysms, although its effectiveness and safety still require evaluation. Numerous studies have examined the outcomes and complication rates in patients treated with FD, resulting in varying findings. This review aimed to summarize the most recent literature concerning the effectiveness of flow diversion devices in posterior circulation aneurysms...

BACKGROUND CONTEXT: Several minimally invasive lumbar interbody fusion techniques may be used as a treatment for spondylolisthesis to alleviate back and leg pain, improve function and provide stability to the spine. Surgeons may choose an anterolateral or posterior approach for the surgery however, there remains a lack of real-world evidence from comparative, prospective studies on effectiveness and safety with relatively large, geographically diverse samples and involving multiple surgical approaches...

BACKGROUND: Controversy exists regarding the optimal methods of employing ultrasound to enhance vascular access. A novel user interface which dynamically displays transverse (short) and longitudinal (long) planes simultaneously was developed to optimize ultrasound-guided vascular access. This study aimed to assess the impact of this novel biplane axis technology on central venous access performance. METHODS: Eighteen volunteer emergency medicine resident physicians and physician assistants were recruited from a single center to participate in this prospective, randomized crossover study...

PURPOSE: To compare radiological and clinical results between the short segment fixation and the long segment fixation in thoracolumbar junction distraction fractures. METHODS: We retrospectively reviewed the prospectively recorded data of patients who underwent posterior approach and pedicle fixation treatment for thoracolumbar distraction fracture (Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association AO/OTA 5-B) with a minimum two years' follow-up...

BACKGROUND: Acute primary angle closure (APAC) is a potentially blinding condition. It is one of the few ophthalmic emergencies and carries high rates of visual morbidity in the absence of timely intervention. Laser peripheral iridotomy (LPI) has been the standard of care thus far. However, LPI does not eliminate the long-term risk of chronic angle closure glaucoma and other associated sequelae. There has been increasing interest in lens extraction as the primary treatment for the spectrum of primary angle closure disease, and it is as yet unclear whether these results can be extrapolated to APAC, and whether lens extraction provides better long-term outcomes...

BACKGROUND: Adult spinal deformity (ASD) is a deformity in the curvature of the adult spine. ASD includes a range of pathology that leads to decreased quality of life for patients as well as debilitating morbidities. Treatment can range from nonoperative management to long-segment surgical corrections and depends greatly on the deformity and patient profiles. If surgical treatment is indicated, circumferential (a combined anterior and posterior approach) fusion is one of the tools in the spine surgeon's armamentarium...

PURPOSE: To report outcomes of pediatric patients with combined hamartoma of the retina and the retina pigment epithelium (CHRRPE) followed up conservatively or after pars plana vitrectomy (PPV). METHODS: This retrospective multicenter study included sixty-two eyes of 59 pediatric patients with CHRRPE from 13 different international centers with an average age of 7.7±4.7 (0.3-17) years at the time of the diagnosis, and having undergone PPV or followed conservatively...

The ultrasound-guided long-axis in-plane approach for central venous catheterization in infants and small children can prevent posterior wall penetration. The combined short-axis out-of-plane and long-axis in-plane approach reportedly prevents such penetration in adults. To test the hypothesis of non-inferiority of the combined approach to the long-axis in-plane approach, we compared the two approaches in infants and small children. Patients were randomized based on whether they underwent ultrasound-guided internal jugular vein catheterization using the combined or long-axis in-plane approach...

INTRODUCTION: The aim of this study was to compare the reduction quality of the anterolateral (AL) and modified posterolateral approach (PL) in lateral tibial plateau fractures involving the posterior column and central segments. METHODS: Matched pairs of pre-fractured cadaveric tibial plateau fractures were treated by either AL approach (supine position) or PL approach (prone position). Reduction was controlled by fluoroscopy and evaluated as satisfying or unacceptable...

Background: Therapeutic decisions for degenerative cervical myelopathy (DCM) are complex and should consider various factors. We aimed to develop machine learning (ML) models for classifying expert-level therapeutic decisions in patients with DCM. Methods: This retrospective cross-sectional study included patients diagnosed with DCM, and the diagnosis of DCM was confirmed clinically and radiologically. The target outcomes were defined as conservative treatment, anterior surgical approaches (ASA), and posterior surgical approaches (PSA)...
