High resolution manometry (HRM) can provide useful functional information for evaluating patients experiencing recurrent symptoms after failed fundoplication surgery. The study evaluated 28 patients with various symptoms using HRM and compared results to healthy controls. HRM revealed high residual lower esophageal sphincter pressures, low rates of LES relaxation, and high intrabolus pressures in the neo-high pressure zone for most patients experiencing post-fundoplication dysphagia. HRM allows detailed analysis of complex esophageal pathology to provide insight for clinical decision making.

This document discusses current methods for treating deep vein thrombosis (DVT) and the impact of post-thrombotic syndrome (PTS). It provides statistics on the prevalence and costs of DVT and PTS in the US. The document reviews changes to DVT treatment guidelines supporting early thrombus removal through pharmacomechanical thrombolysis. Clinical studies demonstrate pharmacomechanical thrombolysis improves outcomes over anticoagulation alone by increasing patency and reducing long-term PTS symptoms. The document concludes that early thrombus removal through pharmacomechanical techniques is the new standard of care for proximal DVT due to decreased complications and improved patient outcomes compared to anticoagulation or catheter-directed thrombolysis alone.TORO.

This document discusses myths and facts regarding thromboprophylaxis in arthroplasty. It notes that while DVT is common following many surgeries and injuries, fatal PE is rare, around 0.06-0.6%. While pharmacological prophylaxis can reduce DVT rates, it does not consistently reduce fatal PE. Pharmacological options like heparin also have risks of bleeding and wound complications. Guidelines increasingly recommend initial mechanical prophylaxis which has fewer risks and provides immediate protection during the highest risk period within 24 hours of surgery. Overall, the optimal prophylaxis strategy remains unclear but a multimodal approach balancing thrombosis and bleeding risks is considered closest to ideal.trombectomy

Catheter-based therapy for acute pulmonary embolism involves the use of devices in the pulmonary artery with or without low-dose thrombolysis. Recent literature does not prove that ultrasound-accelerated thrombolysis is superior to other catheter-directed methods. Guidelines recommend catheter-directed thrombolysis for massive pulmonary embolism or intermediate-high risk patients who cannot receive systemic thrombolysis due to bleeding risk. The procedure involves placing infusion catheters in the pulmonary arteries to deliver low-dose thrombolytics over several hours.Acs0617 Infrainguinal Arterial Procedures

DEB vs. DES for treating critical limb ischemia in below-the-knee arteries
The document discusses studies comparing drug-eluting balloons (DEBs) and drug-eluting stents (DESs) for treating critical limb ischemia (CLI) in below-the-knee (BTK) arteries. One randomized controlled trial found DEBs reduced restenosis and target lesion revascularization rates compared to plain balloon angioplasty but did not improve biological or clinical outcomes compared to DESs. Further studies are still needed to determine the effectiveness of DEBs in long BTK lesions and whether newer coating technologies can achieve similar results to DESs. For lesions up to 10cm, DESs are currently preferredAsymptomatic Carotid Stenosis

An intramural hematoma (IMH) is a thickening of the aortic wall due to bleeding within the media in the absence of an intimal tear. It is considered a precursor to aortic dissection and is classified as a class 2 aortic dissection. A penetrating atherosclerotic ulcer (PAU) is caused by the erosion of an atherosclerotic plaque through the internal elastic lamina into the media. It is classified as a class 4 aortic dissection. Both IMH and PAU can lead to complications like intramural hematoma expansion, pseudoaneurysm formation, aortic dissection, and rupture.

Recent symptomatic patients with carotid artery stenosis can be treated with either urgent carotid endarterectomy (CEA) or carotid artery stenting (CAS). While early studies found CEA to have better outcomes, more recent trials like CREST showed comparable rates of stroke and death between CEA and CAS. For recently symptomatic patients specifically, CEA may still be preferred to CAS due to concerns about stabilizing carotid plaque after stenting. Operator experience also impacts outcomes, so treatment should be individualized based on each patient's clinical situation.Acs0609 Surgical Treatment Of Carotid Artery Disease

Transradial balloon aortic valvuloplasty (BAV) is a feasible and safe procedure for selected high-risk patients as a bridge to surgical aortic valve replacement or transcatheter aortic valve implantation. A study of 17 patients undergoing transradial BAV found it can be performed safely with proper patient selection using ultrasound to access the radial artery. The procedure resulted in significant reductions in aortic valve gradients and increases in aortic valve area with no major vascular complications within 30 days. Transradial BAV is a viable option for bridging high-risk patients with aortic stenosis to other interventions when transfemoral access is not possible or preferred.Anticoagulation

It states that surgical aortic valve replacement (AVR) improves symptoms and quality of life for AS patients, even in those over 80 years old. However, surgery is denied in 33% of elderly patients with severe AS, often due to older age and left ventricular dysfunction rather than comorbidities alone. Balloon valvuloplasty provides only temporary relief for AS and increased risk of restenosis. Transcatheter aortic valve implantation (TAVI) has been shown to have better 1-year survival rates than surgery for high-risk AS patients.

This document summarizes a seminar on assessing esophageal disorders. It discusses various diagnostic tests that can be used:
1) Tests to detect structural abnormalities like endoscopy and barium swallow x-rays.
2) Tests to detect functional abnormalities like manometry to measure muscle contractions.
3) Tests to detect increased esophageal exposure to stomach acid like 24-hour pH monitoring.
4) Tests of stomach and duodenal function that may relate to esophageal issues like gastric emptying studies.
It then reviews different esophageal disorders like esophagitis, Barrett's esophagus, gastroesophageal flap valve abnormalities, diffuse esophageal spasm, and nutcracker esophagus.De Bortoli N. La Manometria del Tratto Superiore. ASMaD 2016

This document provides an overview of dysphagia (difficulty swallowing) including its causes, presentations, investigations, and management approaches. Dysphagia can result from problems in the oral, pharyngeal, or esophageal phases of swallowing. Common causes include strokes, neurological diseases, head and neck cancers. Investigations may include barium swallows, endoscopy, biopsy, and esophageal manometry. Newer techniques like high-resolution manometry and functional luminal imaging probe allow more detailed assessment of esophageal motility and function. Management is tailored to the underlying cause but may include dietary modifications, swallowing exercises, or medical/surgical interventions in severe cases.Ad

The document discusses several studies by Dubecz et al. on trends in adenocarcinoma (adeno-CA) incidence and esophageal cancer (EC) cure and resection rates in the modern era. It notes increasing adeno-CA incidence rates over time, higher rates in white men, stage-by-stage incidence data, and modern cure rates for localized and regional EC from resection. Resection rates for non-metastatic EC in the US are presented from several data sources, along with median lymph nodes removed and percentage of patients with adequate lymph node dissection.Stent Presentation at STS 2009 San francisco

This study evaluated the use of self-expanding metal stents, plastic stents, and hybrid stents to treat 133 patients with malignant and benign esophageal diseases over an 8-year period at a single institution. Stent placement was successful in relieving obstruction in 91% of patients with a median hospital stay of 1 day. Complications included migration in 9.7% of cases, impaction in 13% requiring endoscopic disimpaction, and tumor ingrowth in 5.2% of uncovered metal stents. Stent placement was found to be a generally safe, quick, and reliable procedure for palliating malignant esophageal obstructions.High Resolution Manometry Introduction2

High-resolution manometry uses a catheter with 36 solid-state pressure sensors spaced 1 cm apart to measure esophageal motility. It provides 2D and 3D spatial-temporal plots of pressure data along the esophagus. Classic achalasia shows no peristalsis and impaired lower esophageal sphincter relaxation, while other primary motility disorders like jackhammer esophagus have high amplitude contractions over 180 mmHg with double peaks and prolonged contractions over 6 seconds. HRM allows diagnosis of different motility disorders based on patterns of peristalsis, LES relaxation, and contraction amplitudes.Da Poszter Bdi 旦Ck 2007 Grazdubeczattila

Der Fallbericht beschreibt eine 49-j辰hrige Patientin, die nach einer laparoskopischen Cholezystektomie mit einer intraabdominellen Blutung und darauf folgender Reoperation aufgrund eines Pseudoaneurysmas des Arteria cystica konfrontiert war. Nach der Behandlung und Entfernung des Pseudoaneurysmas verlief der post-operative Verlauf unauff辰llig, und die Patientin wurde schlielich beschwerdefrei entlassen. Hemobilie stellt eine seltene Komplikation nach Cholezystektomie dar, die gegebenenfalls einen chirurgischen Eingriff erforderlich macht, wenn die interventionelle Therapie nicht m旦glich ist.Gallengangverletzungen Nach Cholezystektomie 2007 旦Ck Graz Finaldubeczattila

Die Studie beleuchtet die Rate von Gallengangsverletzungen nach Cholezystektomie mit einer H辰ufigkeit von 1,6% bei 2850 untersuchten Operationen. Es wird diskutiert, dass visuelle Illusionen und der Schwierigkeitsgrad der Operationen h辰ufige Fehlerursachen sind und dass intraoperative Cholangiographie als pr辰ventive Strategie dienen kann. Auch wenn die Raten konstant bleiben, ist eine Verbesserung der chirurgischen Techniken notwendig, um diese Komplikationen zu verringern.Coursebooklet

A 29-year-old woman had been chronically treated for Crohn's disease for years based on a biopsy suggesting a mild case. However, during a surgery, a retained surgical sponge was discovered in her small intestine that had been there since a previous surgery, causing her symptoms. A review of previous samples found threads from the sponge. It is believed the sponge had migrated through her intestines without causing an open wound. Her true diagnosis was misdiagnosed Crohn's disease due to the retained foreign body.who tanulm叩ny

The document summarizes WHO's perspective on proposed reforms to Hungary's health insurance system. The WHO has two main concerns: 1) There is no logical link between the problems identified in Hungary's system and the solution of introducing competitive private health insurance. 2) Analyzing the system using labels like "Beveridge" and "Bismarck" is outdated and misleading. The WHO believes the reforms will greatly increase costs without clear benefits and that Hungary should learn from countries with similar systems rather than those proposed as models.Ad

- 1. THE CHALLENGE OF DIAGNOSTIC ASSESSMENT OF A FAILED FUNDOPLICATION: BENEFITS OF HIGH RESOLUTION MANOMETRY OF THE GE-JUNCTION Attila Dubecz MD ; Renato Salvador MD; Marek Polomsky MD; Thomas J. Watson MD; Carolyn Jones MD; Jeffrey H. Peters MD Department of Surgery, University of Rochester, School of Medicine and Dentistry, Rochester, NY Background Study Aim Conclusions Functional information allowing insight into the cause of recurrent symptoms in symptomatic patients following failed fundoplication can be key to clinical decision making. Evaluate manometric signs of outflow obstruction in patients with post-fundoplication dysphagia. HRM revealed high residual pressures, low percent LES relaxations and high intrabolus pressure of the neo-high pressure zone in virtually all patients with post-fundoplication dysphagia. The image based analysis and high density of recording sides coupled with software interpolation available in HRM, allows novel and clinically useful observations in the evaluation of complex esophageal pathology. Patients and Methods Results Patients: 28 patients (5 male / 23 female) Symptoms : 17 dysphagia, 8 chestpain, 5 heartburn, 5 regurgitation, 2 cough, 2 vomiting Manometric Data-acquisition and Analysis : ManoScan & ManoView TM (Sierra Scientific Instruments) Intrabolus pressures: MATLAB TM Impaired Relaxation We compared the manometric results of post-fundoplication patients with and without dysphagia with 50 healthy controls.
