Consenso chileno de diagnóstico y manejo de neoplasias quísticas pancreáticas. Club de páncreas Chile-SCHGE

Pancreatic cystic neoplasms (PCN) are frequently detected on abdominal images performed for non-pancreatic indications. Their prevalence in asymptomatic population ranges from 2.7 to 24.8%, and increases with age. There are several types of pancreatic cysts. Some may contain cancer or have malignant potential, such as mucinous cystic neoplasms, including mucinous cystadenoma (MCN) and intraductal papillary mucinous neoplasms (IPMN). In contrast, others are benign, such as serous cystadenoma (SCA). However, even those cysts with malignant potential rarely progress to cancer. Currently, the only treatment for pancreatic cysts is surgery, which is associated with high morbidity and occasional mortality. The Board of the Chilean Pancreas Club of the Chilean Gastroenterology Society developed the first Chilean multidisciplinary consensus for diagnosis, management, and surveillance of PCN. Thirty experts were invited and answered 21 statements with five possible alternatives: 1) fully agree; 2) partially agree; 3) undecided; 4) disagree and 5) strongly disagree. A consensus was adopted when at least 80% of the sum of the answers "fully agree" and "partially agree" was reached. The consensus was approved by the Board of Directors of the Chilean Pancreas Club for publication.

Disección endoscópica submucosa para el tratamiento de neoplasias incipientes del tubo digestivo: experiencia en un centro universitario de alto volumen / Experience with endoscopic submucosal dissection for the treatment of early neoplasms of the digestive tract

Background: Endoscopic submucosal dissection (ESD) allows en-bloc resection of early gastro-intestinal neoplasms (EGIN) with healing potential. Aim: To describe the results of patients treated with ESD for EGIN by our team. Patients and Methods: Descriptive study of patients with EGIN who underwent ESD with curative intention between January 2008 and March 2020. Results: One hundred thirty-two ESD were performed in 127 patients. 77% were gastric lesions, 14% colorectal, 8% esophageal and 1% duodenal. En-bloc resection was achieved in 98.4% of ESDs. Eighty eight percent of patients met curative standards. Overall, cancer-specific, and recurrence-free survival were 95%, 100% and 98% respectively. Conclusions: ESD allows en-bloc resections with curative potential in selected patients, but with a significant reduction in morbidity and mortality and less impact on quality of life. Our results suggest the feasibility to perform ESD in our country with results comparable to those reported in the literature.

Risk factors for severe postoperative complications after gastrectomy for gastric and esophagogastric junction cancers / Fatores de risco para complicações pós-operatórias graves após gastrectomia por câncer do estômago e junção esofagogástrica

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.

Survival and perioperative morbidity of totally laparoscopic versus open gastrectomy for early gastric cancer: analysis from a single latin american centre / Comparação da sobrevida e morbidade perioperatória da gastrectomia totalmente laparoscópica vs. laparotômica para tratamento do câncer gástrico precoce em um centro latino-americano

ABSTRACT Background: Laparoscopic gastrectomy has numerous perioperative advantages, but the long-term survival of patients after this procedure has been less studied. Aim: To compare survival, oncologic and perioperative outcomes between completely laparoscopic vs. open gastrectomy for early gastric cancer. Methods: This study was retrospective, and our main outcomes were the overall and disease-specific 5-year survival, lymph node count and R0 resection rate. Our secondary outcome was postoperative morbidity. Results: Were included 116 patients (59% men, age 68 years, comorbidities 73%, BMI 25) who underwent 50 laparoscopic gastrectomies and 66 open gastrectomies. The demographic characteristics, tumour location, type of surgery, extent of lymph node dissection and stage did not significantly differ between groups. The overall complication rate was similar in both groups (40% vs. 28%, p=ns), and complications graded at least Clavien 2 (36% vs. 18%, p=0.03), respiratory (9% vs. 0%, p=0.03) and wound-abdominal wall complications (12% vs. 0%, p=0.009) were significantly lower after laparoscopic gastrectomy. The lymph node count (21 vs. 23 nodes; p=ns) and R0 resection rate (100% vs. 96%; p=ns) did not significantly differ between groups. The 5-year overall survival (84% vs. 87%, p=0.31) and disease-specific survival (93% vs. 98%, p=0.20) did not significantly differ between the laparoscopic and open gastrectomy groups. Conclusion: The results of this study support similar oncologic outcome and long-term survival for patients with early gastric cancer after laparoscopic gastrectomy and open gastrectomy. In addition, the laparoscopic approach is associated with less severe morbidity and a lower occurrence of respiratory and wound-abdominal wall complications.

RESUMO Racional: A gastrectomia laparoscópica tem numerosas vantagens perioperatórias, mas a sobrevivência em longo prazo após este procedimento tem sido menos estudada. Objetivo: Comparar resultados de sobrevivência, oncológica e perioperatória entre a gastrectomia completamente laparoscópica vs. aberta para câncer gástrico precoce. Método: Este estudo foi retrospectivo e os principais resultados foram a sobrevivência global e específica de cinco anos, contagem de linfonodos e taxa de ressecção R0. Resultado secundário foi a morbidade pós-operatória. Resultados: Foram incluídos 116 pacientes (59% homens, idade 68 anos, comorbidades 73%, IMC 25) que foram submetidos a 50 gastrectomias laparoscópicas e 66 gastrectomias abertas. As características demográficas, a localização do tumor, o tipo de operação, a extensão da dissecção dos linfonodos e do estágio não diferiram significativamente entre os grupos. A taxa geral de complicações foi semelhante em ambos os grupos (40% vs. 28%, p=ns) e complicações classificadas Clavien 2 (36% vs. 18%, p=0,03), respiratórias (9% vs. 0%, p=0,03) e as da parede abdominal (12% vs. 0%, p=0,009) foram significativamente menores após a gastrectomia laparoscópica. A contagem de linfonodos (21 contra 23, p=ns) e a taxa de ressecção R0 (100% vs. 96%; p=ns) não diferiram significativamente entre os grupos. A sobrevida global de cinco anos (84% vs. 87%, p=0,31) e a sobrevida específica (93% vs. 98%, p=0,20) não diferiram significativamente entre os grupos de gastrectomia laparoscópica e aberta. Conclusão: Estes resultados suportam resultados oncológicos similares e sobrevida em longo prazo para pacientes com câncer gástrico precoce após gastrectomia laparoscópica e gastrectomia aberta. Além disso, a abordagem laparoscópica está associada com morbidade menos grave e menor ocorrência de complicações respiratórias e da parede abdominal.

Miotomía endoscópica por vía oral (POEM) en un paciente pediátrico para tratamiento de la acalasia esofágica / Per oral endoscopic myotomy in a pediatric patient with achalasia

INTRODUCCIÓN: La acalasia es el trastorno motor primario más frecuente del esófago. Su incidencia reportada es baja, aún más en pacientes pediátricos. La miotomía de Heller laparoscópica corresponde al estándar actual de tratamiento. Durante los últimos años la miotomía endoscópica por vía oral (POEM) se ha posicionado como una alternativa terapéutica segura y tan efectiva como el Heller para la acalasia esofágica. OBJETIVO: Describir la técnica de POEM y reportar el primer caso pediátrico en nuestro país. CASO CLÍNICO: Paciente de 11 años, previamente sano, que se presentó con disfagia ilógica progresiva y baja de peso. El estudio concluyó una acalasia tipo II. Fue sometido a POEM y cursó un postoperatorio sin incidentes. A un año de la intervención se ha documentado resolución de la sintomatología, seguimiento endoscópico y manométrico sin complicaciones. CONCLUSIONES: El caso descrito corresponde al primer POEM en un paciente pediátrico en nuestro país. La acalasia esofágica es infrecuente en pediatría y el POEM ha demostrado éxito clínico y seguridad comparables a la miotomía de Heller laparoscópica en el corto y mediano plazo. El seguimiento a largo plazo permitirá determinar su rol definitivo en el tratamiento de pacientes pediátricos con acalasia esofágica.

INTRODUCTION: Achalasia is the most common primary motor disorder of the esophagus. Its reported incidence is low, even more in pediatric patients. Laparoscopic Heller myotomy is the current stan dard of treatment. During the last years, per-oral endoscopic myotomy (POEM) has been positioned as a safe and effective therapeutic alternative as the Heller procedure for esophageal achalasia. OBJECTIVE: To describe the POEM technique and report the first pediatric case in our country. CLINICAL CASE: 11-year-old patient, previously healthy, who presented with progressive dysphagia for solids and liquids and weight loss. The study concluded a type II achalasia. The patient underwent a POEM and had a postoperative course without incidents. One year after the intervention, symptomatic, endoscopic and manometric resolution have been documented. CONCLUSIONS: The described case is the first POEM in a pediatric patient in our country. Esophageal achalasia is uncommon in pediatrics and POEM has demonstrated clinical success and safety comparable to laparoscopic Heller myotomy in short and medium term. Long-term follow-up will determine its definitive role in the treatment of pediatric patients with esophageal achalasia.

Resección endoscópica por tunelización submucosa de un leiomioma de la unión gastroesofágica: reporte de un caso / Submucosal tunneling endoscopic resection of a gastroesophageal junction leiomyoma: report of a case

Resumen Introducción Los tumores submucosos del tracto gastrointestinal alto tienen potencial de malignidad y también pueden ser una carga para el paciente, por lo que se requiere disponer de un tratamiento seguro y eficaz. El surgimiento de la técnica de resección endoscópica por tunelización submucosa (STER) en los últimos años ha mostrado resultados prometedores. Caso clínico Se presenta el caso de un hombre de 47 años asintomático, en quien, en el contexto de un estudio preoperatorio de cirugía bariátrica, se pesquisa una lesión subepitelial en la unión gastroesofágica. La endosonografía alta es compatible con un leiomioma esofágico. Se realiza STER con éxito y sin complicaciones; a las 48 h es dado de alta. El estudio histopatológico confirmó un leiomioma esofágico. Discusión La técnica STER ha demostrado consistentemente ser segura y eficaz en el tratamiento de los tumores submucosos de la unión gastroesofágica. El desafío es difundir la técnica por el resto del país, para mayor beneficio de los pacientes.

Introduction Upper gastrointestinal submucosal tumors are potentially malignant lesions; so safe and efficient treatments are needed. In recent years, submucosal tunneling endoscopic resection (STER) has emerged as a novel therapeutic technique, with promising results. Case report 47-year-old male patient, previously asymptomatic, who was found to have a subepithelial lesion at the gastroesophageal junction. Upper endoscopic ultrasound was compatible with a leiomyoma. He underwent STER to remove the tumor and recovered with any complications. The biopsy confirmed an esophageal leiomyoma. Discussion STER has become a highly feasible and safe therapeutic option for submucosal tumors of the gastroesophageal junction. The challenge is to spread knowledge about this technique, to maximize patient's benefit.

The minimally invasive approach has been introduced with the aim of reducing postoperative morbidity. Aim To describe the surgical technique and the results of transthoracic minimally invasive esophagectomy (MIE) in semiprone position. Material and Methods Descriptive cohort study. Patients with an elective MIE for cancer were included between April 2013 and May 2017. Demographic, perioperative, pathology and survival variables were recorded. Results We included 33 patients (24 men, age 69 years, 91% with comorbidities). The predominant location of the tumor was in the middle and lower thirds of the esophagus (90%). Fifteen (45%) patients received neoadjuvant treatment. There were no cases of conversion to thoracotomy. The reconstruction was performed with stomach in 93%. Cervical anastomosis was performed in 66% and thoracic anastomosis in 30%. The operative time was 420 (330-570) minutes and bleeding 200 (20-700) cc. The 90-day mortality rate was 0%. Overall morbidity was 78%, there was a 15% occurrence of pneumonia and 9% required a reoperation. The hospital stay was 23 (11-81) days. The histology was squamous carcinoma in 51% and adenocarcinoma in 45%. Margins were RO at 87%. The lymph node count reached 30 (9-45) lymph nodes. Overall 2-year survival is 68%. Conclusion The preliminary results of this technique are favorable, without any case of postoperative mortality. The oncological results demonstrate a high percentage of RO surgery and adequate lymph node count.

Quiste esplénico no parasitario: revisión de la experiencia en un hospital clínico universitario / Non parasitic splenic cysts: single-center experience at a university hospital

Introducción: Las lesiones quísticas esplénicas son poco frecuentes; pueden ser clasificadas en primarias y secundarias según la presencia de revestimiento epitelial. Los quistes parasitarios son provocados por especies de Equinococcus y su manejo es específico. Suelen ser lesiones asintomáticas y el tratamiento depende de su tamaño y de la aparición de manifestaciones clínicas. El abordaje quirúrgico tradicional ha sido la esplenectomía, pero con el reconocimiento de las complicaciones inmunológicas, han tenido auge las alternativas que conservan parénquima esplénico. Objetivo: Comunicar la experiencia en el manejo quirúrgico de esta enfermedad en nuestro centro. Resultados: Se presenta la serie de 11 casos de quistes esplénicos no parasitarios que recibieron tratamiento quirúrgico durante los últimos 15 años. La mayoría de las intervenciones fueron laparoscópicas y no se registró morbimortalidad. Discusión: En el tratamiento de los quistes del bazo no parasitarios actualmente se reconoce el valor de preservar parénquima y función esplénica. La esplenectomía, cirugía cuyo estándar actual es mediante laparoscopia, ha sido progresivamente desplazada por alternativas conservadoras. Las opciones terapéuticas dependen del desarrollo de síntomas, del tamaño y de la ubicación de las lesiones. Conclusiones: Los quistes esplénicos son poco frecuentes. Ante la necesidad de tratamiento quirúrgico el abordaje laparoscópico y las cirugías que conservan parénquima esplénico deberían ser de elección.

Introduction: Splenic cysts are rare. They have been classified in primary or secondary lesions based on the presence or absence of an epithelial lining. Parasitic cysts are caused by Echinococcus spp. and have a particular management. Splenic cysts are usually asymptomatic, treatment depends on the development of symptoms and diameter. Traditionally, splenectomy has been the standard surgery, but updated knowledge about the role of the spleen in preventing some infections has led to more conservative options. Objective: To report our experience in surgical management of the disease. Results: Our series includes 11 patients with non-parasitic splenic cysts treated surgically, during the last 15 years. Most were laparoscopic interventions and no morbidity or mortality was registered. Discussion: Surgical treatment for non-parasitic splenic cysts actually favours conservative techniques; salvage of the spleen whenever possible is fully justified based on updated knowledge of the role it plays in promoting protection against infection. Splenectomy, nowadays performed by laparoscopy, has been partially displaced. Treatment options depends on the cyst diameter, development of symptoms and localization. Conclusions: Splenic cysts are unfrequent. If surgical treatment is needed, laparoscopy and interventions conserving splenic parenchyma should be the election.

Trombosis venosa mayor asociada a catéter de hipotermia terapéutica en un paciente con paro cardiorrespiratorio recuperado: comunicación de un caso y revisión de la literatura / Venous thrombosis secondary to catheter insertion for hypothermia after cardiac arrest: Report of one case

To improve survival and reduce neurological injury, the use of mild hypothermia following cardiac arrest has been recommended. We report a 65 years old woman who presented an out-of-hospital ventricular fibrillation and cardiac arrest. The patient was comatose following initial resuscitation and was admitted into the ICU, where cooling was initiated using an intravascular catheter. After 48 hours, rewarming was initiated. Although no neurological impairment was observed, physical examination of the right inguinal area and echo-Doppler examination revealed an extensive catheter-related thrombophlebitis with right ileocaval vein occlusion., with high risk of masive and life threatening pulmonary embolism. We report a clinical case and review the literature to point out the need for a high index of diagnostic suspicion of deep venous thrombosis in these specific setting.

Plastinación: una técnica moderna al servicio de la anatomía / Plastination: a modern anatomical technique

La preservación y el mantenimiento de los cadáveres y especímenes anatómicos han llevado a la búsqueda de técnicas diferentes y a la utilización de sustancias distintas al formaldehído con el fin de minimizar los riesgos de exposición a vapores químicos y a agentes biológicos y de disponer de preparados anatómicos con mayor durabilidad, conservando las características anatómicas y facilitando la docencia y la investigación en la disciplina. Una de estas técnicas es la plastinación. Presentamos los resultados obtenidos con ella en la Facultad de Medicina de la Universidad de Antioquia.

The preservation and maintenance of anatomical specimens and corpses have created the need for new techniques and for the use of substances different from formaldehyde, in order to lessen the risks of exposure to this substance and to biological agents, and to increase the availability and durability of anatomical pieces preserving their characteristics in order to facilitate teaching and research. In the eighth decade of the XX century the German anatomist von Hagens patented the plastination technique that consists of replacing the water of tissues by silicones, polymers or resins. The plastination process includes four steps: fixation, dehydration, impregnating and curing. There are some difficulties in Colombia regarding the availability of acetone, polymers and silicones as well as a lack of adequate infrastructure for the plastination process; because of this we have modified the technique using other substances at different pressure and temperature conditions; we report the modifications with which we have obtained very good results.

Ureterocervicopexia laparoscópica / Laparoscopic urethrocervicopexia

El objetivo de este trabajo es evaluar los resultados del Burch modificado laparoscópico, para ello se realizó estudio prospectivo con todas las pacientes que ingresaron al protocolo de Burch Laparoscópico. Se hizo un estudio clínico, cistoscopía. QTT, prueba de Marshall a todas las pacientes. La técnica consiste en una uretrocervicopexia laparoscópica transabdominal usando malla de prolene y clips de titanio. Desde agosto de 1995 hasta 1997 se han operado 44 pacientes. Se incluyeron sólo 33, que completaron al menos 6 meses de evolución. La edad promedio 46,3 años (39,56). El promedio de días de estadía hospitalaria fue de 1 paciente (la misma); clipeo transfixiante vesical. Promedio seguimiento 16,17 meses. Todas las pacientes mejoraron la continencia. Un 87,9 por ciento mejoró en un 100 por ciento. Las complicaciones fueron pocas y de fácil manejo, explicables por la inevitable curva de aprendizaje. Los resultados son comparables a otras técnicas quirúrgicas

Evaluación del bienestar fetal con doppler de arterias umbilicales / Evaluation of fetal well-being with dopplers of umbilical arteries

Objetivo: incorporar el Doppler de arterias umbilicales como método complementario en la evaluación del bienestar fetal en embarazos de alto riesgo. Diseño: medición de flujo en arterias umbilicales. Se utiliza curva de normalidad elaborada por Trudinger, para la proporción A/B y los criterios de Ray y Freeman para la interpretación del Test No Stressante. Lugar: Servicio de Gíneco-Obstetricia Hospital del Cobre, Fundación de Salud El Teniente Rancagua. Pacientes: 38 pacientes con embarazos de alto riesgo y distribuidas en 4 grupos según patología agregada del embarazo. Intervenciones: se efectúa ecografía-Doppler y monitoreo fetal a todas las pacientes. Se exige que el intervalo entre el Doppler y el parto no sea mayor a 14 días; y 24 horas para el Test No Stressante o Monitoreo fetal contínuo intraparto. Resultado Final: solamente en los casos de retardo del crecimiento intrauterino hubo alteración del doppler, sin embargo, hay monitoreos fetales anormales en los 4 grupos de embarazos. Mediciones y Resultados: En 2 de las 38 pacientes se encuentran valores anormales del Doppler y corresponden a 2 fetos con retardo del crecimiento intrauterino. En los 13 casos de colestasia el Doppler es normal. En 11 de las 38 pacientes se encuentran monitoreos fetales anormales sin que exista concordancia con alteración del Doppler. Conclusiones: el Doppler es útil en la evaluación del bienestar fetal. Los valores de la proporción A/B se elevan en los casos en que existe aumento de la resistencia en el lecho vascular placentario (RCIU). Esto no sucede en la colestasia del embarazo, por lo tanto en esos casos tiene mayor utilidad del monitoreo fetal

Evaluación de fibrosis en la cicatriz uterina postcesárea / Evaluation of fibrosis in cesarean section uterine scar

El Colegio Americano de Obstetras y Ginecólogos recomienda permitir el parto por vía vaginal en pacientes con 1 cicatriz de cesárea previas por el riesgo de ruptura uterina. Efectuamos medición de fibrosis en una muestra de cicatriz uterina y encontramos que el porcentaje más alto de fibrosis correspondió al grupo con 1 cesárea previa (35.7%, p<0.005). Concluimos entonces que la cicatriz uterina es de características similares después de 1, 2 o más cesáreas previas y el riesgo de ruptura uterina sería similar

Cicatriz uterina post-cesárea / Post-cesarean uterine scar

El Colegio Americano de Obstetras y Ginecólogos recomienda permitir el parto por vía vaginal en pacientes con una cicatriz de cesárea. Se excluyen de esta recomendación las mujeres con 2 o más cesáreas por el riesgo de ruptura uterina. Efectuamos medición de fibrosis en una muestra de cicatriz uterina, y encontramos que el porcentaje más alto de fibrosis (35,7%) correspondió al grupo con una cesárea previa. Concluimos entonces que la cicatriz uterina es de características similares después de 1, 2 o más cesáreas previas, y el riesgo de ruptura sería similar
