Background and study aims Both Heller myotomy (HM) and per-oral endoscopic myotomy (POEM) are efficacious therapies for achalasia. The efficacy and safety of POEM vs HM in Latin America and specifically in patients with Chagas disease is unknown. Patients and methods Consecutive patients undergoing either HM or POEM for achalasia were included from nine Latin American centers in a prospective registry over 5 years. Technical success was defined as undergoing a successful myotomy. Clinical success was defined as achieving an Eckardt score < 3. Data on demographics, procedure info, Eckardt score, and adverse events (AEs) were collected. Student’s t test, Chi squared, and logistic regression analyses were conducted. Results One hundred thirty-three patients were included (59 male; 44 %; mean age 47). POEM was performed in 69 patients, HM in 64 patients. A total of 35 patients had Chagas disease, 17 of 69 in the POEM group, 18 of 64 in the HM group. Both groups had significant reduction in Eckardt scores (P < 0.00001), but successful initial therapy was significantly higher in the POEM group compared to the HM group (P = 0.01304). AEs were similar in both group (17 % vs 14 %) and consisted of pneumothorax (n = 3 vs 2), bleeding requiring transfusion (n = 3 vs 2), and mediastinitis (n = 3 vs 1). Hospital stay was longer in the HM group than in the POEM group (P < 0.00001). In the Chagas subgroup, post-procedure Eckardt score in the POEM group was significantly reduced by 5.71 points (P < 0.00001) versus 1.56 points in the HM group (P = 0.042793). Conclusion Both HM and POEM are efficacious for achalasia, but POEM was associated with higher initial therapy success and shorter hospital stay in Latin America. In Chagas patients with achalasia, POEM was significantly more effective than HM.
ObjectiveThis study aimed to develop and validate a patient-reported outcome measure (PROM) in acute pancreatitis (AP) as an endpoint centred on the patient.DesignA PROM instrument (PAtieNt-rePoRted OutcoMe scale in acute pancreatItis, an international proSpEctive cohort study, PAN-PROMISE scale) was designed based on the opinion of patients, professionals and an expert panel. The scale was validated in an international multicentre prospective cohort study, describing the severity of AP and quality of life at 15 days after discharge as the main variables for validation. The COSMIN (COnsensus-based Standards for the selection of health status Measurement INstruments) methodology was applied. Both the design and validation stages considered the content and face validity of this new instrument; the metric properties of the different items, reliability (reproducibility and internal consistence), the construct, structural and criterion validity, responsiveness and interpretability of this scale.ResultsPAN-PROMISE consists of a seven-item scale based on the symptoms that cause the most discomfort and concern to patients with AP. The validation cohort involved 15 countries, 524 patients. The intensity of symptoms changed from higher values during the first 24 hours to lower values at discharge and 15 days thereafter. Items converged into a unidimensional ordinal scale with good fit indices. Internal consistency and split-half reliability at discharge were adequate. Reproducibility was confirmed using test–retest reliability and comparing the PAN-PROMISE score at discharge and 15 days after discharge. Evidence is also provided for the convergent-discriminant and empirical validity of the scale.ConclusionThe PAN-PROMISE scale is a useful tool to be used as an endpoint in clinical trials, and to quantify patient well-being during the hospital admission and follow-up.Trial registration numberNCT03650062
Con la introducción de la manometría esofágica de alta resolución se revelaron patrones no identificados previamente de la función esofágica. De igual forma, este metodo diagnóstico adiciona patrones de presión topográfica de la presión esofágica, lo que lleva al desarrollo de nuevas herramientas para el análisis y clasificación de desórdenes motores esofágicos. En la actualidad la clasificación de Chicago3.0 la herramienta de análisis de los diferentes trastornos motores esofágicos. En Colombia, cada día se ve el crecimiento en la realización de este estudio. El artículo propone hacer una revisión de cómo realizar e interpretar una manometría esofágica de alta resolución y clasificar los diferentes trastornos de la motilidad esofágica según la última actualización de la clasificación de Chicago 3.0.
Background This paper aims to determine factors associated with difficult biliary cannulation (DBC) that are identifiable before procedures. Methods This is a nested case-control study within a historical cohort in adult patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) from 2015-2019 in the Hospital Universitario San Ignacio, Colombia. This study assessed the associations among variables that could be identified before or at the beginning of procedures and the probability of DBC. These associations were evaluated through a bivariate and multivariate analysis. The study used criteria for DBC defined by the European Society of Gastrointestinal Endoscopy. Results A total of 498 ERCP performed in 376 patients were analyzed. Of all procedures, 144 (29%) fulfilled criteria for DBC. The multivariate analysis showed an association between DBC and the acute care hospital setting (OR:2.92; CI95% 1.70-5.01; P<0.001), redundant papilla (OR:7.26; CI95% 3.38-15.61; P<0.001), or peridiverticular papilla (OR:2.45; CI95% 1.38-4.36; P=0.002). No association was found between DBC and endoscopist’s experience, bilirubin levels, or dilation of the biliary tract. Conclusion The DBC is a frequent event. Alterations in the papilla and ERCP performed in the acute care hospital setting are the principal factors associated with DBC. This information might be useful to predict DBC and establish healthcare and administrative strategies to reduce its implications.
El megaesófago se presenta entre el 5 % y el 20 % de pacientes con acalasia, un trastorno motor esofágico primario reconocido hace más de 300 años, a considerarse en todo paciente con disfagia no explicada por un proceso obstructivo o inflamatorio luego de un estudio endoscópico detallado. Se presenta el caso de un paciente con disfagia progresiva, en quien se documentó megaesófago como complicación de una acalasia de largo tiempo de evolución, no tratada. Se descartó la enfermedad de Chagas mediante enzimoinmunoensayo (ELISA) e inmunofluorescencia indirecta (IFI), tal como recomiendan las guías actuales. Ante la baja frecuencia de esta entidad en nuestro medio y las implicaciones terapéuticas que tiene para los pacientes con acalasia, se realizó una revisión narrativa en la literatura sobre su diagnóstico y alternativas de manejo.
