ABSTRACT
ABSTRACT Background: Gastrectomy is the main treatment for gastric and Siewert type II-III esophagogastric junction (EGJ) cancer. This surgery is associated with significant morbidity. Total morbidity rates vary across different studies and few have evaluated postoperative morbidity according to complication severity. Aim: To identify the predictors of severe postoperative morbidity. Methods: This was a retrospective cohort study from a prospective database. We included patients treated with gastrectomy for gastric or EGJ cancers between January 2012 and December 2016 at a single center. Severe morbidity was defined as Clavien-Dindo score ≥3. A multivariate analysis was performed to identify predictors of severe morbidity. Results: Two hundred and eighty-nine gastrectomies were performed (67% males, median age: 65 years). Tumor location was EGJ in 14%, upper third of the stomach in 30%, middle third in 26%, and lower third in 28%. In 196 (67%), a total gastrectomy was performed with a D2 lymph node dissection in 85%. Two hundred and eleven patients (79%) underwent an open gastrectomy. T status was T1 in 23% and T3/T4 in 68%. Postoperative mortality was 2.4% and morbidity rate was 41%. Severe morbidity was 11% and was mainly represented by esophagojejunostomy leak (2.4%), duodenal stump leak (2.1%), and respiratory complications (2%). On multivariate analysis, EGJ location and T3/T4 tumors were associated with a higher rate of severe postoperative morbidity. Conclusion: Severe postoperative morbidity after gastrectomy was 11%. Esophagogastric junction tumor location and T3/T4 status are risk factors for severe postoperative morbidity.
RESUMO Raciona l: A gastrectomia é o tratamento principal para o câncer de junção esofagogástrica (EGJ) e Siewert tipo II-III. Ela está associada à morbidade significativa. As taxas de morbidade total variam entre os diferentes estudos e poucos avaliaram a morbidade pós-operatória de acordo com a gravidade da complicação. Objetivo: Identificar os preditores de morbidade pós-operatória grave. Métodos: Este foi um estudo de coorte retrospectivo de um banco de dados prospectivo. Foram incluídos pacientes tratados com gastrectomia para câncer gástrico ou EGJ em um único centro. A morbidade severa foi definida como escore de Clavien-Dindo ≥3. Análise multivariada foi realizada para identificar preditores de morbidade grave. Resultados: Duzentos e oitenta e nove gastrectomias foram realizadas (67% homens, mediana de idade: 65 anos). A localização do tumor foi EGJ em 14%, o terço superior do estômago em 30%, o terço médio em 26% e o terço inferior em 28%. Em 196 (67%), foi realizada gastrectomia total com dissecção de linfonodos D2 em 85%. Duzentos e onze pacientes (79%) foram submetidos à gastrectomia aberta. O estado T foi T1 em 23% e T3/T4 em 68%. A mortalidade pós-operatória foi de 2,4% e a taxa de morbidade foi de 41%. A morbidade severa foi de 11% e foi representada principalmente por fístula esofagojejunal (2,4%), fístula duodenal (2,1%) e complicações respiratórias (2%). Na análise multivariada, a localização do EGJ e os tumores T3/T4 foram associados com maior morbidade pós-operatória grave. Conclusão: Morbidade pós-operatória severa após gastrectomia foi de 11%. A localização do tumor na junção esofagogástrica e o estado T3/T4 são fatores de risco para a morbidade pós-operatória grave.

Contar con instrumentos validados en Chile para Disfunción Eréctil (DE), motivó el validar la versión española del Índice Internacional de Función Eréctil (IIEF), en población chilena. Se realizó un estudio cuantitativo no experimental transversal, de muestra no probabilística por conveniencia, con 95 varones adultos de tres centros de salud (Concepción, Talcahuano y Santiago), durante Noviembre 2012 y Junio 2013. Expertos ciegos realizaron entrevista clínica utilizando criterios DSM-V y causas médico-quirúrgicas de DE. Luego de aplicación piloto y adaptación del IIEF, se logró la versión IIEF-Ch aplicándola a toda la muestra. Se analizaron los resultados con SPSS 15.0, obteniéndose alta correlación entre variables (X2: 956.533) y alta adecuación muestral (0,893); dos factores que explican el 81.59% de la varianza del instrumento, con alta confiabilidad (.971) y adecuada validez de criterio, alta sensibilidad (84.5%) y especificidad aceptable (91.9%). La IIEF-Ch es un instrumento válido y confiable para estudios sobre DE en Chile.
Having instruments validated in Chile for Erectile Dysfunction (ED), motivated the validation of the Spanish version of the International Index of Erectile Function (IIEF), in Chilean population. A non-experimental quantitative study of non-probabilistic sample was carried out for convenience, with 95 adult males from three health centers (Concepción, Talcahuano and Santiago), during November 2012 and June 2013. Blind experts conducted a clinical interview using DSM-V criteria and medical-surgical causes of ED. After the pilot application and adaptation of the IIEF, version IIEF-Ch was achieved by applying it to the entire sample. The results were analyzed with SPSS 15.0, obtaining high correlation between variables (X2: 956,533) and high sample adequacy (0,893); two factors that explain 81.59% of the variance of the instrument, with high reliability (.971) and adequate criterion validity, high sensitivity (84.5%) and acceptable specificity (91.9%). The IIEF-Ch is a valid and reliable instrument for studies on ED in Chile.

Background: The laparoscopic approach for the treatment of gastric tumors has many advantages. Aim: To evaluate the results of a laparoscopic gastrectomy program developed in a public hospital. Patients and Methods: Retrospective review of epidemiological, perioperative and follow-up data of patients who were treated with a laparoscopic gastrectomy due to gastric tumors between 2006 and 2013. A totally laparoscopic technique was used for all cases. Complications were evaluated according to the Clavien-Dindo classification. Results: Fifty one patients, aged 65 (36-85) years, underwent a laparoscopic gastrectomy. In 22 patients a total gastrectomy was performed. Conversion rate to open surgery was 8%. Operative time was 330 (90-500) min and bleeding was 200 (20-500) ml. Median hospital stay was 7 (3-37) days. Postoperative morbidity was present in 17 (33%) patients, 3 (6%) patients had complications grade 3 or higher and one patient died (1.9%). Tumor pathology was adenocarcinoma in 39 patients. A complete resection was achieved in 97%. Twenty nine patients (74%) with gastric adenocarcinoma had early gastric cancer and 84% of patients were in stage one. Median lymph node count was 24. Median follow-up was 26 (1-91) months. There was no cancer related mortality among patients subjected to a curative resection. Overall survival for patients with adenocarcinoma was 92% at 3 years. Conclusions: This study supports the feasibility and safety of a laparoscopic gastrectomy program in a public hospital; with low morbidity, adequate lymph node dissection and long-term survival. This approach must be considered an option for selected patients with gastric cancer.

Libman-Sacks endocarditis is a non-infectious valvular damage associated with autoimmune disorders such as Systemic Lupus Erythematosus and Antiphospholipid Syndrome. We report a 17-year-old female consulting in the emergency room due to a right hemiparesis and aphasia. A magnetic resonance imaging showed multiple infarctions in the territory of the left middle cerebral artery, presumably of embolic origin. A trans-esophageal echocardiogram showed a vegetation in the mitral valve. Blood cultures were negative. Antinuclear antibodies and serological tests for antiphospholipid syndrome were positive. Oral anticoagulation was started and the patient was discharged. After six months of follow up, antiphospholipid antibodies are still positive.

La incidencia del divertículo de Meckel es de 2% en la población general. Las complicaciones de los divertículos de Meckel se presentan en 4 a 30% de las personas afectadas, más de 50% de los casos complicados se producen en pacientes menores de 10 años de edad. El vólvulo del divertículo de Meckel es una complicación poco frecuente con una incidencia de 3,2%. Reportamos el caso clínico de un paciente de 64 años que se presenta con vólvulo de un divertículo de Meckel asociado a obstrucción intestinal y peritonitis. La radiografía de abdomen demostró niveles hidroaéreos compatibles con el diagnóstico de obstrucción intestinal. En la tomografía abdominal y pelviana se observan asas de intestino delgado con pared engrosada, aglutinadas en un plastrón y llenas de contenido líquido localizadas en la pelvis. Los hallazgos de la cirugía fueron asas de yeyuno e ileon muy dilatadas, hacia la región periumbilical e hipogástrica se observa un plastrón inflamatorio dentro del cual se encuentra un divertículo de Meckel volvulado que se origina del ileón terminal, se realiza resección de un segmento intestinal de 4 cm, donde está la base del divertículo, y anastomosis primaria con sutura continua de ácido poliglicólico en dos planos. El paciente se recuperó sin complicaciones en el postoperatorio. El estudio histopatológico no encontró mucosa heterotópica gástrica o tejido pancreático en la pared del divertículo.
Meckel's diverticulum has a 2% incidence in the general population. Only 4% to 30% of all patients with Meckel's diverticulum develop complications. Most Meckel's diverticulum complications appear in patients aged 10 years or less. Among these, Meckel's diverticulum volvulus is unusual with a 3% incidence. We report a 64 years old patient with a Meckel's diverticulum volvulus associated with intestinal obstruction and peritonitis. Plain abdominal X rays showed air-fluid levels. An abdominal and pelvic CAT scan showed small bowel loops forming an inflammatory mass and filled with intestinal fluids inside the pelvis. During surgery an inflammatory mass encapsulating a twisted Meckel's diverticulum originating from the terminal ileon was observed. A segmental resection of the diverticulum's base and primary anastomosis in two planes with polyglycolic acid suture, was performed. The patient had an uneventful postoperative period with no complications. The histopathological report did not found heterotopic gastric mucosa or pancreatic tissue in the diverticulum's wall.
