Summary The Chicago Classification of esophageal motility disorders improved the differentiation of achalasia subtypes and tailored treatment. Heller myotomy (HM) and pneumatic dilation are two established treatments for achalasia. Peroral endoscopic myotomy (POEM) has become a third definitive option and is on the rise. Using the National Inpatient Sample (NIS) database, we evaluated patients hospitalized with achalasia and associated surgical and endoscopic interventions from 2013 to 2017 and compared patients undergoing HM versus POEM. The NIS database was queried to include patients with achalasia. Patients who underwent HM, POEM (only 2017 due to lack of distinct procedure code in 2013), pneumatic dilation, or esophagectomy were identified. Adverse events during the hospitalization were also queried using diagnosis codes. From 2013 to 2017, patients hospitalized with achalasia increased from 16 850 to 19 485. There were reductions in the number of esophageal dilations (10.6–5.4%, P < 0.001) and HM (18.7–13.1%, P < 0.001). In 2017, 580 POEMs were performed. Compared with patients undergoing HM in 2017, patients who had POEM had higher mean age > 64 (P = 0.004), Charlson comorbidity index (P < 0.001), disease severity (P < 0.001), and likelihood of mortality (P < 0.001). There were no differences in length of stay, mortality, or total costs between the HM and POEM groups. Patients hospitalized with achlasia increased from 2013 to 2017, possibly due to the growth and accessibility of high-resolution esophageal manometry. As expertise in POEM increases, the number of POEM performed is anticipated to rise with possible further reductions in other treatment modalities for achalasia.

Endoscopic Myotomy

Achalasia is a primary esophageal motility disorder characterized by the loss of inhibitory neurons in the myenteric plexus, resulting in impaired relaxation of the esophagogastric junction. Achalasia is an incurable disease, and the treatment modalities are aimed at disruption of the esophagogastric junction and vary widely from pharmacological to endoscopic to surgical. Traditional endoscopic therapy includes pneumatic dilation, botulinum toxin injection, and peroral endoscopic myotomy. This review aims to provide an overview of the endoscopic management of achalasia, while focusing on the utilization of peroral endoscopic myotomy and other novel approaches.

Abstract Background Recurrent spontaneous epistaxis is the most common clinical manifestation and the most debilitating symptom in hereditary haemorrhagic telangiectasia (HHT) patients. To this date, there exist only a classification of HHT patients by different genetic mutations. There is no standard classification for the mucocutaneous endonasal manifestations of HHT. The aim of the present study was to document the variety of endonasal HHT lesions using digital microscopy and to propose a clinical classification. Methods We recorded the endonasal HHT lesions of 28 patients using a digital microscope. We reconstructed the 3D images und videos recorded by digital microscope afterwards and classified the endonasal lesions of HHT in two classes: Grade A, presence of only flat telangiectasias in the mucosa level and Grade B, (additional) presence of raised berry or wart-like telangiectasia spots. We investigated also Haemoglobin level by routine laboratory procedures, plasma VEGF level by ELISA, Severity of epistaxis by epistaxis severity score (ESS) and quality of life by a linear visual analogue scale (VAS). Results We found a higher quality of life and a lower severity of epistaxis in Grade A patients in comparison to Grade B patients. No difference in plasma VEGF level and in Haemoglobin between Grad A patients and Grade B patients could be detected. Plasma VEGF levels showed no gender specific differences. It could also not be correlated to the extranasal manifestation. Conclusion The classification for endonasal manifestation of HHT proposed in this study indicates severity of epistaxis und quality of life. Digital microscopy with the ability of 3D reconstruction of images presents a useful tool for such classifications. The classification of endonasal HHT lesions using digital microscopy allows to evaluate the dynamic of HHT lesions in the course of time independent of examiner. This allows also to evaluate the efficacy of the different treatment modalities by dynamic of HHT lesions. Moreover digital microscopy is very beneficial in academic teaching of rare diseases.

Fetoscopic Laser Coagulation

Invasive treatment modalities for severe chronic twin-to-twin transfusion syndrome (TTTS), such as fetoscopic laser coagulation of communicating vessels, have revived the need for detailed studies of placental angioar-chitecture. We describe a practical placental vascular injection technique using alcohol-resistant tissue-staining dyes. Injection of color-coded gelatin-dye mixtures effectively delineated the intertwin vasculature, and allowed unequivocal macroscopic classification of vascular communications as artery-to-artery, vein-to-vein, or deep artery–to-vein anastomoses. The existence of deep artery–to-vein anastomoses was further confirmed by light microscopic demonstration of venous dye of one twin and arterial dye of the opposite twin within the same stem villus. Furthermore, the injection technique allowed determination of the caliber of the anastomoses, the direction of the artery-to-vein anastomoses, and the relative vascular territory of each twin. Documenting the vascular communications in monochorionic twin placentas with and without TTTS may enhance our understanding of the pathogenesis of chronic TTTS. Correlating the anastomotic patterns and location of the laser coagulation scars with post-ablation outcome will aid in the design of rational therapeutic methods for this often lethal condition.

AbstractTo measure the burden of comorbid diseases using the MED-ECHO database (Quebec), the so-called Charlson index was adapted to International Classification of Disease (ICD-9) codes. The resulting comorbidity index was applied to the study of inpatient death in a group of 62,456 patients having one of the following conditions: ischemic heart disease, congestive heart failure, stroke, or bacterial pneumonia. Multiple logistic regression was used to relate inpatient death to its predictors, including gender, principal diagnosis, age, and the comorbidity index. Various transformations of the comorbidity score were performed, and their effect on predictive accuracy was assessed. The comorbidity index was constantly and strongly associated with death. When gender, age, comorbidity and the principal diagnoses were taken into account, the area under the receiver-operating curve was 0.83. Therefore, the Charlson Index is a useful approach to risk adjustment in outcomes research from administrative databases.

Introduction: Hypertension has been reported as one of the most common risk factor causing atrial fibrillation (AF). Also, hypertension is associated with more persistent AF. However the epidemiology for incidence of hypertensive emergency in AF hospitalization is not well documented. Hypothesis: We hypothesize that frequency of hypertensive emergency has been increasingly associated with Atrial fibrillation. Methods: National inpatient sample from 2005 -2015 was used for the present analysis. Patients over 18 years, with AF as the primary diagnosis were identified using International Classification of Diseases, Ninth Revision-Clinical Modification (ICD-9-CM) code, 427.31. Patients with hypertensive emergency were identified using ICD-9-CM code. 401.0, 402.0, 403.0, 404.0, 405.0. Results: A total of 4,988,269 AF patients over 18 years of age were included in the present analysis. Of these hospitalization 49,423 had hypertensive emergency during hospitalizations and the rest 4,938,846 had no hypertensive emergency. There was a monotonic increase in the trend of rates of hypertensive emergency per 1000 AF hospitalizations, from 2005 - 2015. (P value <0.001) [Figure 1]. Conclusion: There has been a significant increase in the rates of hypertensive emergency among AF hospitalization, over the past decade. Further research is needed to investigate the reason for this increased trend.

The Impact

BACKGROUND In January 2011, Centers for Medicare and Medicaid Services expanded the number of inpatient diagnosis codes from 9 to 25, which may influence comorbidity counts and risk‐adjusted outcome rates for studies spanning January 2011. This study examines the association between (1) limiting versus not limiting diagnosis codes after 2011, (2) using inpatient‐only versus inpatient and outpatient data, and (3) using logistic regression versus the Centers for Medicare and Medicaid Services risk‐standardized methodology and changes in risk‐adjusted outcomes. METHODS AND RESULTS Using 100% Medicare inpatient and outpatient files between January 2009 and December 2013, we created 2 cohorts of fee‐for‐service beneficiaries aged ≥65 years. The acute myocardial infarction cohort and the heart failure cohort had 578 728 and 1 595 069 hospitalizations, respectively. We calculate comorbidities using (1) inpatient‐only limited diagnoses, (2) inpatient‐only unlimited diagnoses, (3) inpatient and outpatient limited diagnoses, and (4) inpatient and outpatient unlimited diagnoses. Across both cohorts, International Classification of Diseases, Ninth Revision ( ICD‐9 ) diagnoses and hierarchical condition categories increased after 2011. When outpatient data were included, there were no significant differences in risk‐adjusted readmission rates using logistic regression or the Centers for Medicare and Medicaid Services risk standardization. A difference‐in‐differences analysis of risk‐adjusted readmission trends before versus after 2011 found that no significant differences between limited and unlimited models for either cohort. CONCLUSIONS For studies that span 2011, researchers should consider limiting the number of inpatient diagnosis codes to 9 and/or including outpatient data to minimize the impact of the code expansion on comorbidity counts. However, the 2011 code expansion does not appear to significantly affect risk‐adjusted readmission rate estimates using either logistic or risk‐standardization models or when using or excluding outpatient data.
