ABSTRACT
El Consenso Venezolano de Enfermedad por Reflujo Gastroesófágico (ERGE) se realizó con el objeto de proveer guías para mejorar la identificación, el diagnóstico y el tratamiento de este trastorno en el país. Los coordinadores establecieron las líneas de consenso, basado en una revisión sistemática de la literatura médica de los últimos 15 años a partir de 1995. Participaron 55 miembros con el aval de sus respectivas cátedras y sociedades locales de gastroenterología. Éstos revisaron y presentaron los temas con sus niveles de evidencia y grados de recomendación para discutirlos y votarlos en una reunión plenaria. Tras un informe final de los miembros, los coordinadores prepararon las declaraciones finales. El consenso concluyó que la enfermedad por reflujo gastroesofágico tiene una prevalencia estimada del 11,54% en Venezuela, a predominio del sexo femenino (Grado B). El diagnóstico es fundamentalmente clínico, basado en la presencia de síntomas típicos y/o atípicos, e incluso síntomas de alarma que sugieren alguna complicación (Grado B). La endoscopia es importante en la investigación de la presencia de esofagitis de reflujo y laringitis de reflujo (Grado B). Las otras pruebas diagnósticas como lo son la pHmetría esofágica de 24 horas con o sin impedancia intraluminal multicanal son importantes en los pacientes que no tienen esofagitis, tienen síntomas atípicos o cuando hay falla en la respuesta al tratamiento médico (Grado B). La radiología, manometría esofágica y el ultrasonido endoscópico no están indicados en el diagnóstico de la ERGE (Grado B). El objetivo del tratamiento es reducir la exposición ácida en el esófago y con esto: aliviar los síntomas, cicatrizar las lesiones en la mucosa esofágica, prevenir la recurrencia y las complicaciones. Los inhibidores de bomba de protones deberían ser la primera opción en el tratamiento en el síndrome de ERGE y en la esofagitis por reflujo tanto en la fase aguda como durante el mantenimiento...
The Venezuelan Gastroesophageal Reflux Disease (GERD) Consensus was carried out in order to provide guidelines to improve the identification, diagnosis and treatment of this illness in Venezuela. The coordinators established the consensuslines, based on a systematic revision of the medical literature of the last 15 years starting from 1995. 55 physicians participated with the support of their respective medical schools and local societies. They revised and presented the topics with their respective evidence levels and recommendation grades to discuss and vote them in a plenary meeting. After a final report of the members, the coordinators prepared the definitive declarations. The consensus concluded that GERD prevalence in Venezuela is 11,54%, higher in women than men (Grade B). The diagnosis is mainly clinical, based on the presence of typical and/or atypical symptoms and alarm symptoms that may suggest the presence of complications (Grade B). Endoscopy is important when reflux esophagitis and laryngitis are present (Grade B). Other diagnostic tests as ambulatory 24 hours pH monitoring with or without multichannel intraluminal impedance are important in patients without esophagitis, with atypical symptoms or when there is flaw in the answer to the medical treatment (Grade B). Radiology, esophageal manometry and endoscopic ultrasonography are not indicated in the diagnosis of GERD (Grade B). The objective of the treatment is to reduce the presence of acid in the esophagus and consequently: alleviate the symptoms and heal lesions in the esophagus mucosa to prevent recurrence and complications. Proton pump inhibitors should be the first option drug in the treatment of GERD syndrome andin esophagitis during the acute and the maintenance phase using standard or half dose (Grade A). So far, pokinetics are drugs with a limited use in GERD patients; they stimulate the esophagus/gastric motility...

Pulmonary atresia with intact ventricular septum represents a congenital cardiac lesion for which the prognosis depends on the patency of the ductus arteriosus. Nine children with pulmonary atresia and intact ventricular septum underwent echocardiographic studies before cardiac catheterization trying to visualize the anatomy of the outflow tract of the right ventricle, the dimension of the ventricular cavity, the characteristics of the tricuspid valve and finally the size and integrity of the interventricular septum. Using Doppler ultrasound it was possible to evaluate the function of the tricuspid valve and the patency of the ductus arteriosus. The results obtained were correlated with the angiographic and anatomic studies. We concluded that noninvasive assessment of this malformation permits an excellent correlation with the angiographic and anatomic studies.

Patients with pulmonary atresia and intact ventricular septum have a poor prognosis with or without conventional surgical treatment. The best results of surgical treatment are obtained in those cases with a mild underdeveloped right ventricle and minor sinusoidal communication in the absence of important dysfunction of the tricuspid valve. We present five cases of pulmonary atresia with intact ventricular septum associated with dysfunction of the tricuspid valve. On the basis of radiographic, electrocardiographic and hemodynamic findings, this group of patients could not be distinguished from others without dysplasia of the tricuspid valve. Echocardiographic and angiocardiographic studies are mandatory in the differential diagnosis. A combination of systemic-pulmonary artery anastomosis associated with pulmonary valvotomy, when possible, and reconstruction of the right ventricular outflow tract are indicated for surgical solution of these malformations. However, tricuspid valve replacement is indicated in some cases.

The clinical presentation and long-term follow-up of 14 cases of tricuspid atresia associated with pulmonary atresia were reviewed. The electrocardiograms, hemodynamic findings and a definition of anatomic types were outlined in order to facilitate therapeutic decisions. In these types of tricuspid atresia the clinical presentation depends on the patent ductus. Despite the caliber of the ductus arteriosus, the poor tolerance to the malformation is frequent and the clinical presentation is similar to those malformations with decreased pulmonary blood flow (cyanosis since birth and hypoxic spells). In considering the age of these patients, the modified Blalock-Taussig anastomosis is the initial procedure. The Fontan procedure should be considered carefully as an alternative in older children.

Thirty healthy individuals with no history of cardiovascular disease were studied to determine the electrocardiographic effects of maximal exercise immediately followed by ingestion of ice water. The subjects were subgrouped according to their training into (A) high (N = 5), (B) moderate (N = 14) and (C) low (N = 11) levels. Electrocardiograms (ECGs) were taken at rest and at rest with ingestion of ice water followed by maximal stress tests. Maximal stress tests were repeated followed by ingestion of ice water at the beginning of and at 2, 3, 6 and 9 minutes of recuperation. The stress test combining maximal effort and ice water ingestion was positive in all members of Group A, in 4 from Group B and in 1 from Group C. A stress test associating maximal effort with ice water ingestion is a useful method of detecting subjects susceptible to changes in ECG which appear to be secondary to coronary spasm. It has a low cost it is simple to perform and represents minimal risk.

Pulmonary atresia with intact ventricular septum is an uncommon congenital cardiac anomaly which very often present varying degrees of downward displacement and dysplasia of the tricuspid valve. We describe a case of pulmonary atresia and intact ventricular septum associated with Ebstein's malformation of the tricuspid valve first diagnosed with echocardiography and confirmed by angiocardiography and anatomic studies.
