Participation of Latin American surgeons in Twitter using the hashtag #SoMe4Surgery and #SoMe4IQLatAm.

Background: In medicine, social networks contribute to the professional training because it is a way to improve the knowledge and skills of students, residents and specialists; additionally, these networks allow the dissemination of evidence. However, Latin American surgeons' influence within this social network is not highlighted. In this study, using the hashtags #SoMe4Surgery and #SoMe4IQLatAm, the participation of Latin American surgeons in Twitter is established. Study Design: This is a prospective cross-sectional study of the academic tweets published in the period between October 13 and October 19, 2020, on Twitter by the academic accounts @Cirbosque and @MISIRG1 who are users of the social network Twitter in Latin America who participate in the network with the hashtags #SoMe4Surgery and #SoMe4IQLatAm with academic use. Results: A total of 56 tweets and 665 retweets were analyzed. Male sex presents greater interaction, as well as Mondays and Tuesdays week days. Geolocation was recorded as 37.1% in Latin America and 17.6% in Europe. #SoMe4Surgery was mentioned in 31 tweets and generated 211,700 impressions and 25,557 interactions, and #SoMe4IQLatam was mentioned in 25 tweets and achieved 57,585 impressions and 21,901 interactions. A growth of the participation rate of 6.5% in @Cirbosque and 10.5% in @ MISIRG1 was estimated for 2021. Conclusion: The use of social networks, particularly Twitter, in the surgeon community has proven to be a valuable tool during the last decade. The tweet that needs to be shared among more surgeons should be linked to the hashtag #SoMe4IQLatAm and #SoMe4Surgery and Twitter surgeon leaders mentions.

Minimal invasive surgery for multiple adhesive small bowel obstruction: Results of a comparative multicenter study.

AIM OF THE STUDY: Laparoscopic adhesiolysis in small bowel obstruction (SBO) is getting increasingly normal. In patients with multiple adhesive SBOs (MASBO), laparoscopic approaches might increase the risk of bowel injury due to the distended and potentially compromised small bowel. It remains a challenge to the surgeons, entails an interdisciplinary team, trying to achieve the least complications as possible. The study aimed to compare surgical outcomes of laparoscopic procedures (multi-port vs. single-port) in the management of MASBO. PATIENTS AND METHODS: Comparative study of 68 patients with post-operative MASBO treated with Single-Port single incision laparoscopic surgery (SILS) and Multi-port Laparoscopic Surgery in two centers of Bogota, Colombia between January 2013 and June 2018. RESULTS: All patients underwent laparoscopic management, 27 patients by SILS, and 41 patients by multi-port. The average surgical time in the multiport approach was 167 min versus SILS with 129 min. Laparoscopic intestinal resection was performed in 4.4% of patients, through multi-port using intracorporeal anastomosis. Mean hospital stay of 3.2 days for the SILS approach versus multi-port in 2.2 days. CONCLUSIONS: Both laparoscopic approaches, in MASBO treatment is feasible in qualified hands. Patient selection and medical judgment seem to be the most essential factors for a positive result.

OBJETIVOS DEL ESTUDIO: Cada día es más frecuente la adherensiolisis laparoscópica en obstrucción del intestino delgado. En pacientes con obstrucciones debidas a múltiples adherencias del intestino delgado (OMAID), los abordajes laparoscópicos pueden incrementar el riesgo de daño de víscera hueca debido a la presencia de asas distendidas. Continúa siendo un reto para el cirujano, requiriendo un grupo interdisciplinario para disminuir las posibles complicaciones. Este estudio busca comparar los desenlaces de abordajes laparoscópicos (Multipuerto vs. monopuerto) en el manejo del OMAID. PACIENTES Y MÉTODOS: Se realizó un estudio de 68 pacientes con OMAID postoperatorio tratado con cirugía laparoscópica de monopuerto y múltipuerto en dos centros de Bogotá, Colombia entre enero de 2013 y junio de 2018. RESULTADOS: Pacientes llevados a manejo laparoscópico, 27 por monopuerto y 41 por múltipuerto, con tiempo quirúrgico promedio de 129 y 167 minutos respectivamente. 4.1% de los pacientes requirieron resección intestinal, todas en pacientes con abordaje múltipuerto con anastomosis intracorpóreas. El tiempo medio de hospitalización fue de 3.2 días para monopuerto y 2.2 días para multipuerto. CONCLUSIONES: Ambos abordajes laparoscópicos son factibles para el manejo del OMAID en manos calificadas. La selección del paciente y el juicio médico parecen ser factores fundamentales en el resultado positivo.

Blunt abdominal trauma managed with mesenteric embolization: case report.

Blunt abdominal trauma occurs in 20% of polytraumatized patients, of which approximately 5% may have mesenteric lesions. We present a case of a woman suffering from a blunt abdominal trauma, who underwent computed tomography with evidence of hematoma on the right flank, which was controlled by angioembolization of the superior mesenteric artery. Treatment of mesenteric lesions will be determined according to the hemodynamic status of the patient, since in view of stability, a choice can be made between open surgery and embolization, but in case of instability, laparotomy is recommended.

El trauma abdominal cerrado se presenta en el 20% de los pacientes politraumatizados, de los cuales aproximadamente el 5% pueden llegar a tener lesiones mesentéricas. Presentamos el caso de una mujer que sufre un traumatismo abdominal cerrado a la cual se le realizó tomografía computarizada con evidencia de un hematoma en el flanco derecho, que se logra controlar por angioembolización de la arteria mesentérica superior. El tratamiento de las lesiones mesentéricas se determinará según el estado hemodinámico del paciente, pues ante la estabilidad se puede escoger entre cirugía abierta y embolización, pero en caso de inestabilidad se recomienda la laparotomía.

Portosplenomesenteric thrombosis after laparoscopic gastric sleeve.

BACKGROUND: Bariatric surgery is an effective way to lose weight and the laparoscopic gastric sleeve is one of the techniques currently used. Portosplenomesenteric venous thrombosis is a complication that occurs in patients undergoing this surgical technique. At the moment there are no protocols to reduce the risk of this thrombotic event, so we show our experience and propose an algorithm. CASE REPORT: A total of 620 patients were evaluated, six of whom presented between postoperative days 10 to 20 abdominal pain, nausea and dehydration. Therefore, a double contrast abdominal computed tomography scan was carried out, which demonstrated portomesenteric and portoesplenomesenteric thrombosis, in addition to two patients with signs of intestinal ischemia, which required reoperation. One of the patients died of pulmonary thromboembolism.

ANTECEDENTES: La cirugía bariátrica es una forma eficaz de perder peso, y la manga gástrica laparoscópica es una de las técnicas usadas actualmente. La trombosis venosa portoesplenomesénterica es una complicación que se presenta en los pacientes sometidos a esta técnica quirúrgica. En el momento no existen protocolos para disminuir el riesgo de este evento trombótico, por lo cual mostramos nuestra experiencia y proponemos un algoritmo. CASOS CLÍNICOS: Se evaluaron 620 pacientes, de los cuales seis, entre los días 10 y 20 de posoperatorio, presentaron dolor abdominal, náuseas y deshidratación. Se les realizó tomografía computarizada de abdomen con doble contraste, que demostró trombosis portomesentérica y portoesplenomesentérica; además, dos pacientes tuvieron signos de isquemia intestinal y requirieron reintervención quirúrgica. Uno de los pacientes falleció por tromboembolia pulmonar.

Evaluation of gastroesophageal reflux after standardized gastric sleeve with the Gastroesophageal Reflux Disease Questionnaire (GerdQ).

OBJECTIVE: To evaluate the appearance of gastroesophageal reflux in our population after sleeve gastrectomy as management for obesity, with the Gastroesophageal Reflux Disease Questionnaire (GerdQ). METHOD: Retrospective study of patients undergoing sleeve gastrectomy during 2016 and 2017, having ruled out gastroesophageal reflux (GER) with pre-surgical upper digestive endoscopy, and post-operative evaluation with the GerdQ scale. RESULTS: 129 patients were included in the study, average age was 45 years, gender of greater male appearance was 77.5%, the most frequent comorbidities were hypothyroidism 25.6% and hypertension 23.3%. 12.4% had a score greater than or equal to 8, 14 were women and 2 men, there was no statistically significant relationship with the preoperative mass index. CONCLUSIONS: Standardizing the gastric sleeve technique in the bariatric surgery services, taking into account the technical factors associated with post-operative GERD de novo, decreases its appearance as evaluated by the GerdQ scale.

OBJETIVO: Evaluar la aparición de reflujo gastroesofágico (RGE) posterior a gastrectomía en manga como manejo para la obesidad, con el Gastroesophageal Reflux Disease Questionnaire (GerdQ). MÉTODO: Estudio retrospectivo de pacientes llevados a gastrectomía en manga durante 2016 y 2017, habiendo descartado RGE con endoscopia digestiva alta prequirúrgica, y evaluación posoperatoria con la escala GerdQ. RESULTADOS: Se incluyeron en el estudio 129 pacientes, con un promedio de edad de 45 años, el 77.5% de sexo masculino y como comorbilidad más frecuente hipotiroidismo (25.6%) e hipertensión arterial (23.3%). El 12.4% tenían un puntaje ≥ 8, 14 eran mujeres y 2 hombres, y no hubo relación estadísticamente significativa con el índice de masa corporal preoperatorio. CONCLUSIONES: Estandarizar la técnica de manga gástrica en los servicios de cirugía bariátrica, teniendo en cuenta los factores técnicos asociados a RGE posoperatorio de novo, disminuye la aparición de RGE según lo evaluado por la escala GerdQ.

Anterolateral thigh versus radial forearm flap for cervical esophageal reconstruction in cancer patients: A retrospective cohort study in Colombia.

OBJETIVO: Este estudio tuvo como objetivo describir los resultados clínicos del colgajo anterolateral de muslo y radial de antebrazo, para la reconstrucción hipofaríngea y esofágica en un hospital de cuarto nivel en Bogotá, Colombia. MÉTODOS: Estudio retrospectivo inlcuyo 38 pacientes a los que se les realizó reconstrucción funcional esofágica con colgajo de antebrazo radial o anterolateral de muslo (ALT) entre febrero de 2010 y diciembre de 2017. RESULTADOS: Edad media fue de 51 años. El 80% genero femeninp. Los defectos laringoesofágicos estuvieron presentes en el 80%. Se requirió reconstrucción circunferencial total en el 60% de los pacientes. Se realizaron injertos braquio-radiales en el 26% y colgajos anterolaterales de muslo en el 74%. La tasa global de complicaciones tempranas fue del 30%, de las cuales el 20% fueron fístulas (braquio-radial, 2,8%; colgajo libre de ALT, 8,3%). Las complicaciones tardías (20%) incluyeron estenosis y obstrucción de la luz del injerto distal. Solo el 10% de los pacientes no pudieron tolerar la alimentación oral y el 50% de este paciente necesitó gastrostomía permanente. En cuanto al seguimiento oncológico durante el postoperatorio de 24 meses, no se observó recidiva tumoral. CONCLUSIÓN: Los resultados funcionales de la reconstrucción con colgajo braquio-radial y ALT fueron satisfactorios. Nuestros hallazgos sugieren que la ALT tiene una menor incidencia de complicaciones posoperatorias que el colgajo radial de antebrazo. La elección del tipo de colgajo dependerá del tamaño y la ubicación del defecto. Los defectos pequeños y parcialmente cubiertos se benefician del uso de un colgajo radial, y para reconstrucciones faríngeas más grandes y circunferenciales con posibles requisitos de radioterapia, se benefician de un colgajo ALT. OBJECTIVE: This study aimed to describe clinical outcomes of anterolateral thigh (ALT) and radial forearm flap in hypopharyngeal and esophageal reconstruction in a fourth level hospital in Bogotá, Colombia. METHODS: This retrospective study included 38 patients who esophageal functional reconstruction using radial forearm or ALT flap at our center between February 2010 and December 2017. RESULTS: Mean age was 51 years. About 80% of the included patients were females. Laryngoesophageal defects were present in 80%. Total circumferential reconstruction was required in 60% of patients. Brachial-radial grafts were performed in 26% and anterolateral thigh flaps in 74%. Overall, early complication rate was 30%, which 20% were fistulae (brachial-radial, 2.8%; ALT free flap, 8.3%). Late complications (20%) included stenosis and distal graft lumen obstruction. Only 10% of patients were unable to tolerate oral feeding and 50% of this patient needed permanent gastrostomy. Regarding oncological follow-up during the 24-month post-operative, no tumor recurrence was observed. CONCLUSIONS: Functional outcomes of reconstruction with brachial-radial and ALT flap were satisfying. Our findings suggest that ALT has a lower incidence of post-operative complications than radial forearm flap. The choice of the type of flap will depend on the size and location of the defect. Small and partially covered defects benefit from the use of a radial flap, and for larger and circumferential pharyngeal reconstructions with possible radiotherapy requirements, they benefit from an ALT flap.

Evaluación de factores asociados a formación de colecciones intraabdominales en apendicectomía monopuerto para apendicitis aguda complicada.

OBJETIVO: Comparar los desenlaces entre la apendicectomía por laparoscopia por puerto único y multipuerto, y establecer si existe diferencia en el riesgo de colección intraabdominal posoperatoria. MÉTODO: Se realizó un estudio retrospectivo, observacional, mediante 116 historias clínicas de pacientes llevados a apendicectomía laparoscópica por único puerto y multipuerto en dos centros médicos. RESULTADOS: Desarrollaron colección intraabdominal 12 (10.3%) pacientes. No se encontraron diferencias entre ambas técnicas en cuanto al desarrollo de colección intraabdominal (p = 0.242), no hubo diferencia entre ambas técnicas en cuanto a sangrado intraoperatorio (p = 0.012) y el tiempo quirúrgico fue mayor en el grupo de puerto único (17.4 minutos en promedio). El 62.5% de los pacientes con sangrado > 50 ml desarrollaron colección intraabdominal. CONCLUSIONES: No se evidenció superioridad de ninguna de las dos intervenciones en apendicitis complicada, pero sí se confirma que la apendicectomía laparoscópica por puerto único es un procedimiento seguro, factible, no inferior y con tasas similares de complicaciones en comparación con la técnica convencional de apendicectomía laparoscópica. OBJECTIVE: To compare the decreases between the appendectomy by single port vs. multiport laparoscopy and to establish if there is a difference in the risk of postoperative intra-abdominal collection. METHOD: Retrospective study was carried out using 116 medical records of patients undergoing laparoscopic appendectomy through a single port and multiport in two medical centers. RESULTS: 12 (10.3%) patients developed an abdominal collection. No differences were found between the two techniques in terms of intra-abdominal collection development (p = 0.242), there was no difference between the two techniques in terms of intraoperative bleeding (p = 0.012), the surgical time was greater in the single-port group (17.4 min on average). 62.5% of patients with bleeding > 50 mL developed intra-abdominal collection. CONCLUSIONS: There was no evidence of superiority of either of the two interventions in complicated appendicitis, but it does confirm that single-port laparoscopic appendectomy is a safe, feasible, noninferior procedure and with similar complication rates compared to the conventional laparoscopic appendectomy technique.

Úlcera marginal perforada tras bypass gástrico. ¿Cuál es el manejo ideal? A propósito de un caso.

En la última década, las úlceras marginales en pacientes tras un bypass gástrico se han convertido en un problema mucho más frecuente, y hoy en día aún no está clara su etiología. Se han descrito numerosos factores de riesgo, tales como un alto consumo de tabaco o de antiinflamatorios no esteroideos (AINE), entre otros. Presentamos el caso de una paciente con úlcera gástrica perforada en el remanente gástrico, con antecedente de bypass gástrico hace 4 años, tabaquismo y uso de AINE, por lo que se lleva a manejo laparoscópico con parche de Graham, adecuada evolución clínica y resolución de la sintomatología.In the last decade, marginal ulcers in post-gastric bypass patients have become a much more frequent problem. Multiple risk factors have been described, such as high consumption of tobacco or high consumption of nonsteroidal anti-inflammatory drugs (NSAIDs), among others. We present a case report of a patient with perforated gastric ulcer in the gastric pouch, with a history of gastric bypass 4 years ago associated with smoking and NSAIDs, so it is taken to laparoscopic management with Graham's patch management, adequate clinical evolution and resolution of symptoms.

Laparoscopic Roux-en-Y hepaticojejunostomy reconstruction after iatrogenic bile duct injury: case series report.

INTRODUCTION: Bile duct injury (BDI) is a devastating complication after a cholecystectomy. Laparoscopic management has become a mainstay approach because of the advantages offered to patients; nevertheless, outcomes after repair are influenced by the center, the surgeon's experience, and the type of reconstruction. MATERIALS AND METHODS: Patients with common BDI managed at a referral center from January 2013 to June 2018 with a novel modified and simplified laparoscopic technique for a hepatic duct jejunostomy with a Roux-en-Y reconstruction were retrospectively reviewed. RESULTS: Twenty patients had a BDI (20/5430-0.3%), 8 (40%) had intraoperative diagnosis, and 12 (60%) patients with diagnosis before 72 h. Type E Strasberg classification, the predominant BDI was Strasberg E1 (65%), the average surgery time was 146.5 min (115-178 min), the average intraoperative bleeding was 15-50 cc. The overall complication rate was 10 % (2/20), 1 (5%) patient required, there were no mortalities, and the mean hospital stay was 5 days. One (5%) patient presented bile leak (Type SE4), and 1 (5%) patient required intensive care unit admission after reintervention. Long-term follow-up showed no bile duct stricture, cholangitis, or recurrent choledocholithiasis up to 5 years after the procedure and with a minimum of 1 year minimum follow-up. CONCLUSIONS: This simplified laparoscopic approach to bile duct reconstruction with Roux-en-Y anastomoses appears to be an effective and safe alternative to reconstructive open bile duct surgery, offering to patients the benefits of laparoscopic surgery with a low complication rate.

ANTECEDENTES: La lesión del conducto biliar es una complicación devastadora tras una colecistectomía. El tratamiento laparoscópico se ha convertido en un enfoque principal debido a las ventajas ofrecidas a los pacientes; sin embargo, los resultados después de la reparación están influenciados por el centro, la experiencia del cirujano y el tipo de reconstrucción. MÉTODO: Se revisaron retrospectivamente los pacientes con lesión del conducto biliar tratados con reconstrucción biliar en un centro de referencia, desde enero de 2013 hasta junio de 2018, por vía laparoscópica con una técnica modificada y simplificada con hepatoyeyunostomía en Y de Roux. RESULTADOS: Veinte pacientes de 5,430 tenían lesión del conducto biliar (0,3%), 8 (40%) tuvieron diagnóstico intraoperatorio y 12 (60%) diagnóstico antes de las 72 horas. Todos con una clasificación de Strasberg tipo E, con predominio de E1 (65%). El tiempo quirúrgico promedio fue de 146,5 (rango 115-178) minutos y el sangrado intraoperatorio promedio fue de 15-50 cm3. La tasa general de complicaciones fue del 10% (2/20); 1 (5%) paciente requirió reintervención. No hubo mortalidad y la estancia hospitalaria media fue de 5 días. Un paciente (5%) presentó fuga biliar (tipo SE4) y 1 (5%) paciente requirió ingreso en la unidad de cuidados intensivos después de la reintervención. El seguimiento fue de hasta 5 años tras el procedimiento, con un mínimo de 1 año, y no se han documentado estenosis del conducto biliar, colangitis ni coledocolitiasis recurrente. CONCLUSIÓN: Este enfoque laparoscópico simplificado para la reconstrucción del conducto biliar con anastomosis en Y de Roux parece ser una opción efectiva y segura a la cirugía reconstructiva del conducto biliar abierta, ofreciendo a los pacientes los beneficios de la cirugía laparoscópica y con una baja tasa de complicaciones.

Emergency laparoscopic resection of the anterior rectum due to rectal trauma secondary to compressed air, case report.

In the XIX century, the surgeon faces surgical challenges due to the creation of new technologies. Accidental or compressed air-induced injury to the colon and rectum is rare. We present the case of a 45-year-old patient who consults the emergency department, then a high-pressure rectal pneumatic trauma, with clinical findings of peritonism, managed with a Hartmann-type colostomy. and anterior resection of the rectum using laparoscopy, with findings of rectosigmoid perforation. With this, it can be demonstrated that minimally invasive surgery is a feasible approach in hemodynamically unstable patients without contraindication for pneumoperitoneum.

Biliogastrointestinal reconstruction with duodenectomy and pancreas preservation by laparoscopy after open failed coledocoduodenostomy.

Las lesiones de la vía biliar y las reconstrucciones biliodigestivas son un reto quirúrgico para el cirujano, además de una situación que exige su máxima habilidad y conocimiento. Presentamos el caso de un paciente con una reconstrucción biliodigestiva por una lesión de vía biliar abierta la cual fue fallida. Se decide llevar a reconstrucción biliodigestiva por laparoscopia, con preservación del páncreas, en un asa con hepatoyeyunostomía y gastroyeyunostomía. Este caso ilustra la posibilidad del manejo con cirugía mínimamente invasiva incluso en los casos más graves; sin embargo, se requiere alta experticia al momento de abordarlo.Bile duct injury and bile duct reconstruction are a surgical challenge for the surgeon, in addition to a situation that demands maximum skill and knowledge. We present a case of a patient with a biliodigestive reconstruction due to an open bile duct injury which was failed, it was decided to take a biliodigestive reconstruction by laparoscopy, with preservation of the pancreas, with hepaticoyejunostomy and gastroyejunostomy. This case illustrates the possibility of handling with minimally invasive surgery even in the most severe cases, however, they require high expertise when addressing it.

Early fixation of the flail chest: case report.

ANTECEDENTES: En 1926, Jones y Richardson describen por primera vez el tórax inestable. Desde entonces existe gran controversia sobre el manejo conservador comparado con el manejo quirúrgico. OBJETIVO: Dar a conocer los beneficios, las indicaciones y las contraindicaciones de la fijación temprana de fracturas costales en el tórax inestable. CONCLUSIÓN: La reducción abierta y la fijación temprana de fracturas costales en pacientes con tórax inestable ha demostrado ser un método útil, efectivo y seguro. BACKGROUND: In 1926, Jones and Richardson described flail chest for the first time. Since then, exist great controversy about conservative vs surgical approach. OBJECTIVE: Define the benefits, indications and contraindications of the early fixation of rib fractures in flail chest. CONCLUSION: The open reduction and early fixation of rib fractures for patients with flail chest has proven to be a useful, effective and safe method.

Laparoscopic Common Bile Duct Exploration With Primary Closure After Failed Endoscopic Retrograde Cholangiopancreatography Without Intraoperative Cholangiography: A Case Series from a Referral Center in Bogota, Colombia.

Background: Despite the effectiveness of laparoscopic common bile duct (CBD) surgery, no case series details the use and advantages of laparoscopic CBD exploration (LCBDE) without use of intraoperative cholangiography (IOC) in endoscopic retrograde cholangiopancreatography (ERCP) failure. Therefore, we present a case series regarding our success with LCBDE in managing CBD stones (CBDSs) using laparoscopic technique without IOC. Materials and Methods: We performed a descriptive retrospective observational study. Patients with CBDSs, alone or along with gallbladder stones, were treated through LCBDE with primary CBD closure after failed ERCP. Results: All patients underwent LCBDE with choledocotomy and primary duct closure. Patients with gallbladder stones underwent laparoscopic cholecystectomy (78%). All procedures were successful, and no conversions occurred. Surgery duration averaged 106 minutes. Intraoperative bleeding averaged 15 cc, and no mortalities occurred. No patients required additional surgery or intensive care unit admission. Hospitalization duration averaged 5 days. Conclusions: Therefore, a laparoscopic approach with primary CBD closure after failed ERCP for complex CBDSs is safe and effective.

Acute abdomen in the centanary patient, mesh migration into the sigmoid colon after laparoscopic inguinal hernia repair (TAPP): A case report and review of literature.

BACKGROUND: The complications induced by mesh, such as foreign body reaction, deep-seated infection, mesh migration and perforation into viscera, have been reported sporadically. Colon erosion and penetration by laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair mesh can possibly cause perforation of the colon with acute abdomen. CASE PRESENTATION: A 100-year-old male, who underwent 4 years ago TAPP repair of left inguinal, presented to the emergency department with acute abdomen due to chronic mesh penetration into the sigmoid colon, the migrating mesh generated a free wall perforation with generalized fecal peritonitis. DISCUSSION: Tailoring the mesh, appropriate suture placement and adherence to principles of antisepsis during hernia repair surgery are crucial in avoiding longterm mesh-related complications. CONCLUSION: TAPP is a safe procedure for treat groin hernias, unless, mesh complications like foreign body reaction, deep-seated infection, mesh migration and perforation.

Low intra-operative diagnostic accuracy does not affect postoperative treatment of acute appendicitis.

BACKGROUND: The intra-operative classification of appendicitis defines postoperative treatment. The correct designation can influence patient recovery, complications and hospital costs. Recent research has shown that intra-operative classification criteria varies among surgeons, and is not always the same as the pathologist's report. Classification accuracy can lower costs by preventing unnecessary treatment or sub-optimal interventions. METHODS: During a period of 4 months, N = 133 appendix specimens were received and evaluated by the pathology department of a single teaching hospital. Five surgeons extracted the specimens and one experienced pathologist drew the histopathology reports. A comparison between the surgeons' classifications and the pathologist's was made. Classification accuracy was determined and statistical analyses was performed using chi-square, and p values were obtained. A p < 0.05 was considered significant. RESULTS: A total of N = 133 specimens were obtained, 127 belonged to patients following emergency surgery due to acute abdominal pain; the other six were from elective hemi-colectomies for right colonic adenocarcinomas, and were not included. Of the 127 specimens analyzed, 14 (11%) were negative, 21 (16.5%) were edematous, 81 (63.7%) were phlegmonous and 11 (8.6%) were gangrenous. A total of 18 (14%) perforated appendices were also reported. Surgical accuracy was 60.6% (N = 67) with a statistically significant p < 0.001. Only five patients with incorrect intraoperative classifications received unnecessary or lacked treatment. CONCLUSIONS: An overall accuracy of 60.6% is seen when the surgical classification is compared to the pathological classification. Although the surgeons' accuracy is low when comparing intra-operative versus histopathological classification, this variation in designation does not affect postoperative treatment significantly.

Impacto socioeconómico del manejo actual de la pancreatitis aguda de origen biliar severa: estudio comparativo / Socioeconomic impact of the current management of severe biliary acute pancreatitis: comparative study

RESUMEN Objetivo La pancreatitis aguda de origen biliar es una patología gastrointestinal común, en donde el tratamiento oportuno es el pilar más importante a pesar de sus discrepancias. El objetivo del estudio es establecer el impacto socioeconómico en el manejo actual de esta patología, comparando dos hospitales de tercer nivel de estrato socioeconómico alto y bajo de la ciudad de Bogotá, Colombia. Materiales y Métodos Se realizó un estudio retrospectivo, comparativo de corte transversal entre enero de 2012 y diciembre de 2017, en dos hospitales de Bogotá D. C. Se evaluaron sus características socioeconómicas, género, tiempo de evolución al momento de la consulta, Marshall score, estancia en UCI, estancia hospitalaria, complicaciones, manejo quirúrgico y mortalidad. Resultados Se analizaron 101 pacientes de dos estratos socioeconómicos diferentes (alto y bajo). Se encontró que los pacientes de estrato bajo tienen un riesgo diez veces mayor de requerir un procedimiento quirúrgico. Asimismo, registraron una mayor mortalidad en comparación con pacientes de estrato alto (11,3% vs. 4,2%). También se evidenciaron más complicaciones en el grupo de nivel socioeconómico bajo con respecto al alto, como en la falla exocrina (81,1% vs. 31,3%) y el síndrome compartimental (35,8% vs. 4,2%). Conclusión Se encuentra mayor morbimortalidad en los pacientes de bajo nivel socioeconómico en el contexto de esta patología. Este estudio puede guiar a nuevas investigaciones acerca del impacto socioeconómico en los desenlaces de pancreatitis aguda severa.(AU)

ABSTRACT Objetive Acute pancreatitis of biliary origin is a common gastrointestinal pathology, in which timely management still is the most important. The aims of this research is establish the socioeconomic impact in the current management of severe acute pancreatitis of biliary origin comparing two centers of the third level, one of high socioeconomic population and another of low in Bogotá, Colombia. Materials and Methods A retrospective, cross-sectional comparative study was conducted between January 2012 and December 2017, in two hospitals of Bogotá DC. We evaluated their socioeconomic characteristics, gender, time of evolution at the time of consultation, Marshall score, ICU stay, hospital stay, complications, surgical management and mortality. Results 101 patients from two different socioeconomic strata (high and low) were analyzed, where a 10 times higher risk of requiring a surgical procedure in the group of patients with low stratum was found, as well as a higher mortality compared with those of high stratum. (11.3% Vs 4.2%). There were also more complications in the low socioeconomic group with respect to the high, as in the exocrine failure (81.1% vs 31.3%) and the compartment syndrome (35.8% vs 4.2%). Conclusion There is greater morbidity and mortality in patients of low socioeconomic status in the context of this pathology. This study can guide new research that increases the clarity of the socioeconomic impact on the outcomes of severe acute pancreatitis.(AU)

Laparoscopic management for Wilkie´s syndrome.

INTRODUCTION: Wilkie's syndrome is a rare entity that presents as a chronic intestinal obstruction secondary to mechanical compression of the third portion of the duodenum due to a decreased aorto-mesenteric angle. This entity has a reported incidence of 0.012 to 2.4% and can lead to high morbidity and mortality; In addition, there are major controversies regarding its diagnosis and treatment, which is why the authors present a case report of a patient with a diagnosis of Wilkie's syndrome and its surgical management via laparoscopy. METHODS: A case of a patient with clinical and imaging manifestations of superior mesenteric artery syndrome is presented, along with acritical review of the literature, taking into account articles published in the PubMed and ScienceDirect databases during the past 8 years. CLINICAL CASE: A 27-year-old patient with 20 years of abdominal pain that exacerbated one week before admission, with a clinical and imaging manifestations of Wilkie's syndrome. Patient presents refractoriness to medical management, which led to a surgical approach with laparoscopic duodenum-jejunostomy that was carried out without perioperative complications and satisfactory results. DISCUSSION AND CONCLUSIONS: The superior mesenteric artery syndrome is a rare entity that in some scenarios requires surgical management. The laparoscopic duodeno-jejunostomy is the procedure of choice to manage this entity as evidenced in our case, which is also consistent with what is reported in the world medical literature.

INTRODUCCIÓN: El síndrome de Wilkie es una entidad poco frecuente que se presenta como una obstrucción intestinal crónica secundaria a la compresión mecánica de la tercera porción del duodeno; la compresión es extrínseca por una disminución del ángulo entre la arteria mesentérica superior y la aorta. Esta anomalía tiene una incidencia informada en la bibliografía médica mundial de 0.012 a 2.4% y puede propiciar una elevada morbimortalidad; de forma adicional, existen grandes controversias en relación con su diagnóstico y tratamiento, por lo cual los autores presentan un informe de caso de un paciente con diagnóstico de síndrome de Wilkie y su manejo quirúrgico por vía laparoscópica. MÉTODOS: Se presenta un caso de un paciente con diagnóstico clínico e imagenológico de síndrome de arteria mesentérica superior y se realiza un revisión crítica de las publicaciones, con atención a los artículos publicados en las bases de datos de PubMed y ScienceDirect en los últimos ocho años sobre el síndrome de Wilkie y se completa la revisión con artículos clásicos sobre el tema. CASO: Paciente de 27 años con 20 años de dolor abdominal agudizado una semana antes del ingreso, con diagnóstico clínico e imagenológico de síndrome de Wilkie. El enfermo muestra resistencia al tratamiento médico, por lo que se practicó una duodenoyeyunostomía laparoscópica sin complicaciones perioperatorias y con resultados satisfactorios. DISCUSIÓN Y CONCLUSIONES: El síndrome de arteria mesentérica superior es un trastorno raro que exige medidas quirúrgicas en algunos escenarios. La duodenoyeyunostomía laparoscópica es el procedimiento de elección para tratar esta entidad, como se evidenció en este caso, lo cual concuerda con lo publicado en la bibliografía médica mundial.

[Socioeconomic impact of the current management of severe biliary acute pancreatitis: comparative study]. / Impacto socioeconómico del manejo actual de la pancreatitis aguda de origen biliar severa: estudio comparativo.

OBJETIVE: Acute pancreatitis of biliary origin is a common gastrointestinal pathology, in which timely management still is the most important. The aims of this research is establish the socioeconomic impact in the current management of severe acute pancreatitis of biliary origin comparing two centers of the third level, one of high socioeconomic population and another of low in Bogotá, Colombia. MATERIALS AND METHODS: A retrospective, cross-sectional comparative study was conducted between January 2012 and December 2017, in two hospitals of Bogotá DC. We evaluated their socioeconomic characteristics, gender, time of evolution at the time of consultation, Marshall score, ICU stay, hospital stay, complications, surgical management and mortality. RESULTS: 101 patients from two different socioeconomic strata (high and low) were analyzed, where a 10 times higher risk of requiring a surgical procedure in the group of patients with low stratum was found, as well as a higher mortality compared with those of high stratum. (11.3% Vs 4.2%). There were also more complications in the low socioeconomic group with respect to the high, as in the exocrine failure (81.1% vs 31.3%) and the compartment syndrome (35.8% vs 4.2%). CONCLUSION: There is greater morbidity and mortality in patients of low socioeconomic status in the context of this pathology. This study can guide new research that increases the clarity of the socioeconomic impact on the outcomes of severe acute pancreatitis.

OBJETIVO: La pancreatitis aguda de origen biliar es una patología gastrointestinal común, en donde el tratamiento oportuno es el pilar más importante a pesar de sus discrepancias. El objetivo del estudio es establecer el impacto socioeconómico en el manejo actual de esta patología, comparando dos hospitales de tercer nivel de estrato socioeconómico alto y bajo de la ciudad de Bogotá, Colombia. MATERIALES Y MÉTODOS: Se realizó un estudio retrospectivo, comparativo de corte transversal entre enero de 2012 y diciembre de 2017, en dos hospitales de Bogotá D. C. Se evaluaron sus características socioeconómicas, género, tiempo de evolución al momento de la consulta, Marshall score, estancia en UCI, estancia hospitalaria, complicaciones, manejo quirúrgico y mortalidad. RESULTADOS: Se analizaron 101 pacientes de dos estratos socioeconómicos diferentes (alto y bajo). Se encontró que los pacientes de estrato bajo tienen un riesgo diez veces mayor de requerir un procedimiento quirúrgico. Asimismo, registraron una mayor mortalidad en comparación con pacientes de estrato alto (11,3% vs. 4,2%). También se evidenciaron más complicaciones en el grupo de nivel socioeconómico bajo con respecto al alto, como en la falla exocrina (81,1% vs. 31,3%) y el síndrome compartimental (35,8% vs. 4,2%). CONCLUSIÓN: Se encuentra mayor morbimortalidad en los pacientes de bajo nivel socioeconómico en el contexto de esta patología. Este estudio puede guiar a nuevas investigaciones acerca del impacto socioeconómico en los desenlaces de pancreatitis aguda severa.
