Apendicectomía en pacientes con situs inversus: Serie de tres casos con manejo laparoscópico / Appendectomy in patients with situs inversus: Three cases series with laparoscopic approach

Introducción. La transposición de los órganos debido al situs inversus (SI) es una rara afección que dificulta el diagnóstico de la apendicitis aguda. Esta condición hace que la sintomatología del paciente y los hallazgos al examen físico puedan ser atípicos, lo que demanda el uso de imágenes para la confirmación diagnóstica en la mayoría de los casos. Métodos. Se describieron tres casos de apendicitis en pacientes con diagnóstico de situs inversus. Dos de ellos tenían el antecedente conocido, mientras el tercer caso fue diagnosticado de forma intraoperatoria. Resultados. En dos pacientes se decidió llevar a cirugía vía laparoscópica sin imágenes diagnósticas adicionales. Los pacientes evolucionaron de manera satisfactoria. Conclusión. Siempre se debe considerar la apendicitis dentro de los diagnósticos diferenciales en los pacientes con dolor en fosa ilíaca izquierda. Es fundamental diagnosticar y tratar la apendicitis de manera efectiva para minimizar las complicaciones asociadas. La importancia de la anamnesis y la sospecha clínica del examinador son vitales en estos casos, que se pueden confirmar con las imágenes diagnósticas. Pueden existir casos en donde la condición clínica del paciente no permita la realización de estudios diagnósticos por imágenes; esto apoya cada vez más el uso del abordaje laparoscópico. Se recomienda considerar el abordaje laparoscópico en primera instancia, ya que nos permite la confirmación diagnóstica de situs inversus totalis en caso de que el antecedente sea desconocido y facilita el manejo oportuno de la urgencia.

Introduction. Organ transposition due to situs inversus (SI) is a rare condition that makes the diagnosis of acute appendicitis difficult. This condition entails that the patient' symptoms and physical examination findings may be atypical, which requires the use of images for diagnostic confirmation in most cases. Clinical cases. Three cases of appendicitis in patients diagnosed with situs inversus are described. Two of them had a known medical history, while the third case was diagnosed intraoperatively. Results. In two patients it was decided to undergo laparoscopic surgery without additional diagnostic images. The patients progressed satisfactorily. Conclusion. Appendicitis should always be considered in the differential diagnoses in patients with pain in the left iliac fossa. It is essential to diagnose and treat appendicitis effectively to minimize associated complications. The importance of the anamnesis and the examiner's clinical suspicion are vital in these cases, which can be confirmed with diagnostic images. There may be cases where the patient's clinical condition does not allow diagnostic imaging studies to be performed, increasingly supports the use of the laparoscopic approach. It is recommended to consider the laparoscopic approach in the first instance, since it allows us to confirm the diagnosis of situs inversus totalisin case the history is unknown and facilitates timely management of the emergency.

Comparison of clinical efficacy of different colon anastomosis methods in laparoscopic radical resection of colorectal cancer.

OBJECTIVE: The objective of this study was to investigate the clinical effect of overlap anastomosis and functional end-to-end anastomosis (FEEA) in laparoscopic radical resection of colorectal cancer (CRC). METHODS: The clinical data of 180 patients who underwent laparoscopic radical resection of CRC and side-to-side anastomosis were retrospectively collected; the patients were divided into the Overlap group and FEEA group, according to the anastomosis method that was used to treat them. RESULTS: The Overlap group had a shorter operation time, anastomosis time, post-operative hospital stay, post-operative feeding time, and post-operative exhaust time than the FEEA group (p < 0.05). The total incidence of post-operative complications was 14.4% (13/90) in the FEEA group and 0.7% (6/90) in the Overlap group, and there was no significant difference between the two groups (p > 0.05). CONCLUSIONS: Overlapping anastomosis can shorten the operation time and accelerate the recovery of intestinal function without increasing the incidence of post-operative complications, and it will not affect the quality of life and survival of patients in the short term after surgery.

OBJETIVO: Investigar el efecto clínico de la anastomosis superpuesta y de la anastomosis funcional de extremo a extremo (AFEE) en la resección radical laparoscópica del cáncer colorrectal (CCR). MÉTODO: Se recolectaron retrospectivamente los datos clínicos de 180 pacientes sometidos a resección radical laparoscópica de CCR y anastomosis de lado a lado. Los pacientes se dividieron en grupo de anastomosis superpuesta y grupo AFEE, según el método de anastomosis que se utilizó para tratarlos. RESULTADOS: El grupo de anastomosis superpuesta tuvo un tiempo de operación, un tiempo de anastomosis, una estancia hospitalaria posoperatoria, un tiempo de alimentación posoperatorio y un tiempo de escape posoperatorio más cortos que el grupo AFEE (p < 0.05). La incidencia total de complicaciones posoperatorias fue del 14.4% (13/90) en el grupo AFEE y del 0.7% (6/90) en el grupo de anastomosis superpuesta, y no hubo diferencias significativas entre los dos grupos (p > 0.05). CONCLUSIONES: La anastomosis superpuesta puede acortar el tiempo operatorio y acelerar la recuperación de la función intestinal sin aumentar la incidencia de complicaciones posoperatorias, y sin afectar la calidad de vida y la supervivencia de los pacientes a corto plazo después de la cirugía.

Hidatidosis esplénica única / Isolated splenic hydatid disease

RESUMEN La hidatidosis es una parasitosis endémica en la Argentina. Los órganos más afectados son hígado y pulmón, pero la afectación esplénica única es infrecuente. El objetivo del trabajo es presentar 2 casos de hidatidosis esplénica única. Su diagnóstico presuntivo se realizó mediante el antecedente epidemiológico y los estudios por imágenes. Las serologías resultaron negativas en ambos casos. El tratamiento fue quirúrgico: se realizó esplenectomía laparoscópica total. Esta patología debe sospecharse en zonas endémicas ante la aparición de quistes esplénicos a pesar de presentar serologías negativas. La esplenectomía total evita la recidiva local y cavidades residuales; se prefiere el abordaje laparoscópico al disminuir la estadía hospitalaria y las complicaciones de la pared abdominal.

ABSTRACT Hydatid disease is an endemic parasitosis in Argentina. The liver and lungs are the organs more commonly affected, but isolated splenic involvement is rare. The aim of this study is to report two cases of isolated splenic hydatid disease. The diagnosis was suspected by epidemiology and imaging tests. The serologic tests were negative in both cases. Surgical management was decided and both patients underwent laparoscopic total splenectomy. This disease should be suspected in endemic areas in the presence of splenic cysts despite negative serologic tests. Total splenectomy prevents local recurrence and complications associated with the residual cavity. The laparoscopic approach is preferred as it results in a shorter length of hospital stay and fewer abdominal wall complications.

Resultados de cirugía resectiva colorrectal por Endometriosis Infiltrante Profunda: 6 años de experiencia

Objetivo: Describir los resultados tempranos de la cirugía resectiva colorrectal por Endometriosis Infiltrante Profunda (EIP) en mujeres intervenidas en centro clínico privado, durante los últimos 6 años. Material y Método Estudio transversal que muestra la evolución clínica de pacientes intervenidas quirúrgicamente con resecciones colorrectales por diagnóstico de (EIP), entre los años 2016-2022 en Clínica Indisa. Se agruparon en resecciones discoidales (Grupo I) y segmentarias (Grupo II) Resultados: De los pacientes operados por (EIP) entre los años 2016 al 2022, 160 pacientes fueron sometidas a resecciones colorrectales, 56 en el Grupo I y 104 en el grupo II. Las características demográficas de ambos grupos fueron similares, con excepción del hábito tabáquico que mostró un predominio en el Grupo II. El análisis de las variables quirúrgicas (tipo de abordaje, tasa de conversión, altura de la anastomosis y ostomía de protección) mostró una distribución similar en ambos grupos. En relación a la evolución postoperatoria, el Grupo I presentó una disminución significativa en el tiempo de realimentación con sólidos de 2 vs 3 días (p = 0,001). El inicio del tránsito intestinal, días de hospitalización y presencia de complicaciones Clavien-Dindo > = 3, no presentó diferencias significativas entre ambos grupos. Discusión: La endometriosis afecta, significativamente, a mujeres en todo el mundo, existiendo escasa evidencia que reporte los resultados de las cirugías colorrectales que comparen ambas técnicas, demostrando que el manejo en centros especializados tiene mejores resultados. Conclusión: Al comparar estas dos técnicas de resección colorrectal en DIE, concluimos que los pacientes operados por resección discoidal tienen una realimentación más temprana sin diferencias significativas en el resto de las variables estudiadas.

Objective: To describe the early outcomes of resective colorectal surgery for Deep Infiltrating Endometriosis (DIE) in women treated at private center over the past 6 years. Materials and Methods: This cross-sectional study presents the clinical evolution of surgically treated patients with colorectal resections for DIE diagnosis between 2016 and 2022 at Clínica INDISA. They were grouped into discoid resections (Group I) and segmental resections (Group II). Results: Of patients operated for DIE between 2016 and 2022, 160 underwent colorectal resections, with 56 in Group I and 104 in Group II. The demographic characteristics of both groups were similar, except for smoking habits, which showed a predominance in Group II. The analysis of surgical variables (approach type, conversion rate, anastomotic height, and protective ostomy) showed a similar distribution in both groups. Regarding postoperative outcomes, Group I showed a significant decrease in solid food resumption time, 2 vs 3 days (p = 0.001). The initiation of intestinal transit, hospitalization days, and presence of Clavien-Dindo complications >= 3 did not present significant differences between both groups. Discussion: Endometriosis significantly affects women worldwide, with limited evidence reporting colorectal surgery outcomes comparing both techniques, demonstrating that management in specialized centers yields better results. Conclusion: When comparing these two techniques of colorectal resection in DIE, we conclude that patients undergoing discoid resection have an earlier resumption of solid food intake without significant differences in the remaining studied variables.

Tratamiento de la Colecisto-coledocolitiasis mediante la técnica de Rendez-vous laparo-endoscópico: implementación y desarrollo de la técnica en un hospital universitario

Objetivo: La litiasis biliar es una patología frecuente en Chile y el mundo, que suele presentarse como colecistocoledocolitiasis. Dentro de las alternativas para su manejo está el rendez-vous laparoendoscópico (RVLE), que consiste en una colecistectomía laparoscópica asociada a colangiopancreatografía endoscó-pica retrograda (ERCP). Este trabajo tiene como objetivo evaluar la implementación de esta técnica para el tratamiento de la colecistocoledocolitiasis en un hospital universitario. Materiales y Métodos: Cohorte retrospectiva de 4 años de pacientes con colecistocoledocolitiasis en quienes se realizó un RVLE. Resultados: Se incluyeron 296 pacientes, de edad promedio de 52 años, siendo un quinto mayor de 70 años, y presentando un 29,3% comorbilidades significativas. Un 65,2% fueron urgencias y un 12,2% presentó colangitis aguda. El éxito de la técnica fue de un 82,8%. Los cálculos mayores de 5 mm se asociaron al fracaso de ésta. La principal causa de fracaso fue el no paso de la guía hacia el duodeno (13,5%). La morbilidad, clínicamente significativa, fue de 9,5% y la mortalidad global a los 90 días fue de 0,68%. Discusión: El RVLE es un tratamiento eficaz para la colecistocoledocolitiasis en un tiempo quirúrgico, incluso en pacientes mayores de 70 años con comorbilidades, aunque con mayor morbilidad en colangitis aguda. La colangioresonancia magnética es útil en el diagnóstico y aporta información como el tamaño de los cálculos. El no paso de la guía es la principal causa de fracaso, pero se resuelve en la mayoría de los casos con una ERCP tradicional.

Objective: Gallstone disease is a common condition in Chile and worldwide, often manifesting as cholecystocholedocholithiasis. One of the treatment options is laparoendoscopic rendezvous (RVLE), involving laparoscopic cholecystectomy combined with endoscopic retrograde cholangiopancreatography (ERCP). This study aims to assess the effectiveness of this technique in managing cholecystocholedocholithiasis at a university hospital. Materials and Methods: A retrospective cohort study spanning four years was conducted on patients diagnosed with cholecystocholedocholithiasis who underwent RVLE. Results: The study included 296 patients, with an average age of 52 years. One-fifth of them were over 70 years old, and 29.3% had significant comorbidities. Of these cases, 65.2% were classified as emergencies, and 12.2% presented with acute cholangitis. The overall success rate of the RVLE procedure was 82.8%. Notably, the presence of gallstones larger than 5 mm was associated with a higher likelihood of procedure failure. The primary reason for failure was the inability of the guidewire to advance into the duodenum (13.5%). Clinically significant morbidity occurred in 9.5% of cases, and the overall mortality rate at 90 days was 0.68%. Discussion: RVLE is an effective treatment for cholecystocholedocholithiasis within a single surgical intervention, even in patients over 70-years-old with comorbidities. However, it is important to note that the procedure is associated with increased morbidity when performed in cases of acute cholangitis. Magnetic resonance cholangiopancreatography serves as a valuable diagnostic tool, providing insights into stone size. The most common cause of procedure failure is the inability of the guidewire to pass through, although this issue can often be resolved with a traditional ERCP.

Effect of three training programs on surgical performance in single-port laparoscopic surgery.

OBJECTIVE: The aim of this study was to evaluate the effect of three training methodologies on the acquisition of psychomotor skills for laparoendoscopic single-site surgery (LESS), using straight and articulating instruments. METHODS: A prospective study was conducted with subjects randomly divided into three groups, who performed a specific training for 12 days using three laparoscopic tasks in a laparoscopic simulator. Group-A trained in conventional laparoscopy setting using straight instruments and in LESS setting using both straight and articulating instruments. Group-B trained in LESS setting using straight and articulating instruments, whereas Group-C trained in LESS setting using articulating instruments. Participants' performance was recorded with a video-tracking system and evaluated with 12 motion analysis parameters (MAPs). RESULTS: All groups obtained significant differences in their performance in most of the MAPs. Group-C showed an improvement in nine MAPs, with a high level of technical competence. Group-A presented a marked improvement in bimanual dexterity skills. CONCLUSIONS: Training in LESS surgery using articulating laparoscopic instruments improves the quality of skills and allows smoother learning curves.

OBJETIVO: Evaluar el efecto de tres métodos de entrenamiento en la adquisición de habilidades psicomotrices para la cirugía laparoendoscópica por puerto único (LESS, laparoendoscopic single-site surgery) utilizando instrumental recto y articulado. MÉTODO: Se realizó un estudio prospectivo con sujetos divididos aleatoriamente en tres grupos, quienes realizaron un entrenamiento específico durante 12 días utilizando tres tareas laparoscópicas en un simulador laparoscópico. El grupo A entrenó en el entorno laparoscópico convencional con instrumentos rectos, y en el entorno LESS con instrumentos rectos y articulados. El grupo B entrenó en el entorno LESS con instrumentos rectos y articulados. El Grupo C entrenó en el entorno LESS con instrumentos articulados. El desempeño de los participantes se registró con un sistema de seguimiento en video y fue evaluado con 12 parámetros de análisis de movimiento (MAP, motion analysis parameters). RESULTADOS: Todos los grupos obtuvieron diferencias significativas en su desempeño para la mayoría de los MAP. El grupo C mostró una mejora en nueve MAP, con un alto nivel de competencia técnica. El grupo A mostró una marcada mejora en la habilidad de destreza bimanual. CONCLUSIONES: El entrenamiento en cirugía LESS con instrumentos articulados mejora la calidad de las habilidades adquiridas y permite curvas de aprendizaje más suaves.

Resección laparoscópica de quiste de duplicación gástrica asistida por endoscopia / Laparoscopic resection of gastric duplication cyst assisted by endoscopy

Introducción. Las duplicaciones gástricas son entidades congénitas poco frecuentes que se diagnostican principalmente en las etapas tempranas de la vida, y rara vez en pacientes adultos. El objetivo de este artículo fue presentar el caso de un adulto con esta patología, tratado exitosamente mediante cirugía. Caso clínico. Mujer de 26 años de edad con epigastralgia crónica refractaria a manejo médico, a quien durante endoscopia digestiva superior se le identificó una lesión quística sugestiva de tumor estromal gastrointestinal, confirmada por ultrasonido endoscópico. Resultados. Se realizó una resección quirúrgica laparoscópica asistida por endoscopia, con buena evolución postoperatoria. El estudio anatomo-patológico informó la presencia de un quiste de duplicación gástrica. Conclusiones. A pesar de las ayudas diagnósticas disponibles en la actualidad, esta patología representa un reto diagnóstico importante que, en muchas ocasiones solo puede ser confirmado mediante el estudio anatomo-patológico. En paciente asintomático, continúa la controversia entre observarlo o llevarlo a cirugía, por el riesgo de malignidad. Actualmente, el manejo de las duplicaciones gástricas en adultos se considera eminentemente quirúrgico. Las resecciones laparoscópicas y el uso de endoscopia intraoperatoria permiten garantizar la resección completa de la lesión, preservando la mayor cantidad de tejido sano adyacente y previniendo estenosis o deformidades gástricas que afecten su adecuado funcionamiento.

Introduction. Gastric duplications are rare congenital entities that are diagnosed primarily in early life, and rarely in adult patients. The objective of this article was to present the case of an adult with this pathology, successfully treated by surgery. Clinical case. A 26-year-old woman with chronic epigastralgia refractory to medical management, who during upper digestive endoscopy was identified with a cystic lesion suggestive of gastro-intestinal stromal tumor, confirmed by endoscopic ultrasound. Results. A laparoscopic surgical resection assisted by endoscopy was performed, with good postoperative evolution. The anatomopathological study reported the presence of a gastric duplication cyst. Conclusions. Despite the diagnostic adjuncts currently available, this pathology represents an important diagnostic challenge that, in many cases, can only be confirmed through pathology. In asymptomatic patients, the controversy continues between observing them or taking them to surgery due to the risk of malignancy. Currently, the management of gastric duplications in adults is considered eminently surgical. Laparoscopic resections and the use of intraoperative endoscopy ensure complete resection of the lesion, preserving the greatest amount of adjacent healthy tissue and preventing gastric stenosis or deformities that affect its proper functioning.

Caracterización de los desenlaces quirúrgicos a corto plazo en gastrectomía por laparoscopia en un centro de alto volumen: 10 años de experiencia / Short-term surgical outcomes of laparoscopic gastrectomy in a high-volume center: 10-year experience

Introducción. El cáncer gástrico en Colombia es la segunda neoplasia más común en hombres y la cuarta en mujeres. En los últimos años se han descrito ampliamente los beneficios del abordaje laparoscópico en el cáncer gástrico frente a sangrado, recuperación postoperatoria y complicaciones, sin afectar los resultados oncológicos. Métodos. Estudio observacional retrospectivo de pacientes llevados a gastrectomía laparoscópica en la Clínica Universitaria Colombia durante un período de diez años, entre 2013 y 2023. Se describieron los resultados perioperatorios en cuanto a estancia hospitalaria, sangrado operatorio, duración del procedimiento, complicaciones, causas de reintervención y mortalidad en los primeros 30 días. Resultados. Se incluyeron 418 pacientes, 58,9 % hombres, con una edad promedio de 60,8 años. Se documentó un tiempo quirúrgico promedio de 228,7 minutos, con un sangrado de 150 ml. La media de ganglios linfáticos resecados fue de 26,1 ± 11,4. La estancia hospitalaria en promedio fue de 4 ± 4 días, y se registraron complicaciones en 104 sujetos, con una tasa promedio de 24 %, de las cuales 29 (27,4 %) obtuvieron una clasificación Clavien-Dindo IIIB. Conclusiones. La gastrectomía por laparoscopia en un centro de alto volumen y con cirujanos experimentados en Colombia, tiene resultados perioperatorios similares a lo reportado en la literatura mundial. Aún se requiere de estudios de mayor fuerza de asociación para establecer recomendaciones sobre el uso rutinario de este abordaje en patología maligna avanzada.

Introduction. Gastric cancer in Colombia is the second most common neoplasm in men and the fourth in women. In recent years, the benefits of the laparoscopic approach in gastric cancer against bleeding, postoperative recovery com and complications have been widely described, without affecting oncological results. Methods. Retrospective observational study of patients undergoing laparoscopic gastrectomy at the Clínica Universitaria Colombia over a period of ten years, between 2013 and 2023. Perioperative results were described in terms of hospital stay, operative bleeding, duration of the procedure, complications, causes of reintervention, and mortality in the first 30 days. Results. 418 patients were included, 58.9% men, with an average age of 60.88 years. An average surgical time of 228.7 minutes was documented, with a blood loss of 150 ml. The mean number of lymph nodes resected was 26.1 ± 11.4. The average hospital stay was 4 ± 4 days, and complications were recorded in 104 subjects, with an average rate of 24%, of which 29 (27.4%) obtained a Clavien-Dindo IIIB classification. Conclusions. Laparoscopic gastrectomy in a high-volume center and with experienced surgeons in Colombia has perioperative results similar to those reported in the world literature. Studies with greater strength of association are still required to establish recommendations on the routine use of this approach in advanced malignant pathology.

Laparoscopic approach for xanthogranulomatous pyelonephritis and pyonephrosis.

INTRODUCTION: Xanthogranulomatous pyelonephritis (XGPN) is a rare form of chronic renal inflammation, caused by long-term obstruction of the urinary tract. Pyonephrosis is a severe suppurative complication of acute obstructive pyelonephritis. Although minimally invasive approaches have many advantages, the safe dissection of the kidney may not be always achievable. MATERIALS AND METHODS: We reviewed 27 cases diagnosed with either XGPN or pyonephrosis, who underwent laparoscopic total nephrectomy between October 2016 and March 2022 in our department. All interventions were performed using the Karl Storz 3D laparoscopic system. The surgical approach was standard transperitoneal nephrectomy for the majority of XGPN, while pyonephrosis cases were carried out in a retroperitoneally. All procedures were performed or supervised by the same surgeon. RESULTS: The mean operative time was 269.85 minutes (range 145-360). The mean hemoglobin drop after surgery was 1.41 g/dl (range 0.3-2.3 g/dl). Difficult dissection was encountered in 13 cases (48.14%). Nine out of 13 interventions were carried out in a complete intracorporeal fashion, while conversion to open surgery was needed in 4 cases. Vascular complications involving the major blood vessels comprised of one case of inferior vena cava (IVC) tear. Digestive tract-related complications comprised two fistulas of the descending colon and one peritoneal breach. Multiorgan resection was performed in 6 cases. CONCLUSION: Total nephrectomy in cases of XGPN and pyonephrosis is a challenging procedure. The laparoscopic approach is feasible, as most complications are resolved intracorporeally. However, it may remain reserved for large-volume centers with experienced surgeons.

Protocolo de recuperación mejorada después de cirugía (ERAS) atenúa el estrés y acelera la recuperación en pacientes después de resección radical por cáncer colorrectal: Experiencia en la Clínica Universitaria Colombia / Enhanced Recovery After Surgery (ERAS) protocol attenuates stress and accelerates recovery in patients after radical resection for colorectal cancer: Experience at Clínica Universitaria Colombia

Introducción. El conjunto de estrategias de recuperación mejorada después de la cirugía (ERAS, por sus siglas en inglés) constituye un enfoque de atención multimodal y multidisciplinario, cuyo propósito es reducir el estrés perioperatorio de la cirugía, disminuir la morbilidad y acortar la estancia hospitalaria. Este estudio tuvo como objetivo describir los resultados clínicos de pacientes sometidos a cirugía por cáncer colorrectal, identificando las complicaciones principales y los factores perioperatorios relacionados con el alta temprana. Métodos. Se analizaron los pacientes consecutivos sometidos a cirugía colorrectal entre los años 2020 y 2023, todos los cuales siguieron el protocolo ERAS institucional. Se evaluaron las características clínicas, los factores perioperatorios, los desenlaces postoperatorios y la tasa global de adherencia al protocolo. Resultados. Un total de 456 pacientes fueron sometidos a cirugía colorrectal, 51% de sexo masculino, con edad media de 60 años. La mayoría de las intervenciones se realizaron por laparoscopia (78 %), con una tasa de conversión del 14,5 %. Las complicaciones postoperatorias incluyeron fuga anastomótica (4,6 %), sangrado, infección intraabdominal y obstrucción intestinal. La estancia hospitalaria promedio fue de 4 días y la mortalidad del 2,8 %. La tasa global de adherencia al protocolo ERAS fue del 84,7 %. Conclusiones. El enfoque combinado de cirugía laparoscópica y protocolo ERAS es factible, seguro y se asocia con una estancia hospitalaria más corta. La implementación y adherencia al protocolo ERAS no solo mejora los resultados postoperatorios, sino que también resalta la importancia de acceder a datos sólidos, permitiendo mejorar la atención perioperatoria local.

Introduction. The Enhanced Recovery After Surgery (ERAS) protocol is a multimodal, multidisciplinary approach to care, the purpose of which is to reduce the perioperative stress of surgery, decrease morbidity, and shorten hospital stay. This study aimed to describe the clinical outcomes of patients undergoing surgery for colorectal cancer, identifying the main complications and perioperative factors related to early discharge. Methods. Consecutive patients undergoing colorectal surgery between 2020 and 2023 were analyzed, who followed the institutional ERAS protocol. Clinical characteristics, perioperative factors, postoperative outcomes, and overall protocol adherence rate were evaluated. Results. A total of 456 patients underwent colorectal surgery, 51% male, with a mean age of 60 years. Most interventions were performed laparoscopically (78%), with a conversion rate of 14.5%. Postoperative complications included anastomotic leak (4.6%), followed by bleeding, intra-abdominal infection, and intestinal obstruction. The average hospital stay was 4 days and mortality was 2.8%. The overall adherence rate to the ERAS protocol was 84.7%. Conclusions. The combined approach of laparoscopic surgery and ERAS protocol is feasible, safe, and associated with a shorter hospital stay. Implementation and adherence to the ERAS protocol not only improves postoperative outcomes, but also highlights the importance of accessing solid data, allowing for improved local perioperative care.

Epidemiología de la apendicitis aguda en Colombia: Un análisis de las bases de datos administrativas del Ministerio de Salud / Epidemiology of acute appendicitis in Colombia: An Analysis of the Ministry of Health administrative databases

Introducción. La apendicitis aguda es una afección común, con un pico de incidencia entre los 10 y 20 años. La cirugía es el tratamiento preferido y la apendicectomía por laparotomía sigue siendo el estándar, aunque el abordaje laparoscópico ha mostrado menos complicaciones. El objetivo de este artículo fue caracterizar tanto la enfermedad como el tratamiento quirúrgico en Colombia, usando datos de bases oficiales. Métodos. Se accedió a la base de datos del Sistema Integrado de Información para la Protección Social (SISPRO) del Ministerio de Salud de Colombia en febrero de 2023. Se recogieron datos de los pacientes con diagnóstico de apendicitis y con procedimiento de apendicectomía entre 2017 y 2021, y se analizaron por edad, sexo y ubicación geográfica. Resultados. Entre 2017 y 2021 se diagnosticaron 345.618 casos de apendicitis (51,8 % mujeres), con pico de incidencia a los 15-20 años. Se realizaron 248.133 apendicectomías, el 16,7 % por laparoscopia. Los hospitales con más procedimientos reportados estaban en Bogotá, Yopal, Popayán y Florencia. La mortalidad fue de 0,56 % en hombres y 0,51 % en mujeres. Conclusión. La apendicitis es común, con pico a los 10-19 años. Las mujeres tienen mayor probabilidad de apendicectomía, debido a otras afecciones ginecológicas. El acceso a la apendicectomía disminuye la mortalidad; en estos pacientes, el 16 % fue laparoscópica, lo que sugiere que se necesita más entrenamiento y acceso a esta técnica. Este estudio aporta a la comprensión de la epidemiología de la apendicitis y apendicectomías en Colombia.

Introduction. Acute appendicitis is a common condition, with a peak incidence between 10 and 20 years of age. Surgery is the preferred treatment and laparotomy appendectomy remains the standard, although the laparoscopic approach has shown fewer complications. The objective of this article was to characterize both the disease and the surgical treatment in Colombia, using data from official databases. Methods. The Integrated Information System for Social Protection (SISPRO) database of the Ministry of Health was accessed in February 2023. Data with diagnosis of apendicitis and with appendectomy between 2017 and 2021 were collected. Analysis was done by age, gender, and geographic location. Results. Between 2017 and 2021, 345,618 cases of appendicitis were diagnosed (51.8% females), with peak incidence at 15-20 years of age. A total of 248,133 appendectomies were performed, 16.7% by laparoscopy. The hospitals with most reported procedures were located in Bogotá, Yopal, Popayán, and Florencia. Mortality was 0.56% in men and 0.51% in women. Conclusion. Appendicitis is common, peaking at ages 10-19. Women are more likely undergo appendectomy due to other gynecological conditions. Access to appendectomy improves mortality. In these patients, 16% were laparoscopic, suggesting that more training and access to this technique is needed. This study contributes to the understanding of the epidemiology of appendicitis and appendectomies in Colombia.

Influence of laparoscopic surgery on the outcomes of radical cystectomy within a multimodal rehabilitation protocol.

INTRODUCTION AND OBJECTIVE: The implementation of Enhanced Recover After Surgery (ERAS) multimodal rehabilitation protocols in radical cystectomy has shown to improve outcomes in hospital stay and complications. The aim of this analysis is to evaluate the impact of laparoscopic surgery on radical cystectomy within a multimodal rehabilitation program. MATERIAL AND METHODS: The study was carried out in a third level center between 2011 and 2020 including patients with bladder cancer submitted to radical cystectomy according to an ERAS (Enhanced Recovery After Surgery) protocol and the Spanish Multimodal Rehabilitation Group (GERM) with 20 items to be fulfilled. RESULTS: A total of 250 radical cystectomies were performed throughout the study period, 42.8% by open surgery (OS) and 57.2% by laparoscopic surgery (LS). The groups are comparable in demographic and clinical variables (p > 0.05). Operative time was longer in the LS group (248.4 ±â€¯55.0 vs. 286.2 ±â€¯51.9 min; p < 0.001). However, bleeding was significantly lower in the LS group (417.5 ±â€¯365.7 vs. 877.9 ±â€¯529.7 cc; p < 0.001), as was the need for blood transfusion (33.6% vs. 58.9%; p < 0.001). Postoperative length of stay (11.5 ±â€¯10.5 vs. 20.1 ±â€¯17.2 days; p < 0.001), total and major complications were also significantly lower in this group (LS). The readmission rate was lower in the LS group but not significantly (36.4% vs. 29.4%; p = 0.237). The difference between 90-day mortality in both groups was not statistically significant (2.8% LS vs. 4.3% OS; p = 0.546). The differences were maintained in the multivariate models. CONCLUSIONS: Laparoscopic surgery within a multimodal rehabilitation program increases operative time but significantly decreases intraoperative bleeding, transfusion requirements, postoperative length of stay, and complications.

Malformación linfática quística gigante del hígado: dos casos pediátricos con diferente abordaje quirúrgico / Giant cystic lymphatic malformation of the liver: two pediatric cases with different surgical approach

Introducción. Las malformaciones linfáticas quísticas, también llamadas linfangiomas quísticos, aparecen muy raramente de forma aislada en el hígado. Casos clínicos. Se presentan dos pacientes femeninas de edad preescolar con marcada hepatomegalia, dependiente de lesiones quísticas multitabicadas, secundarias a malformación linfática quística gigante del hígado, que fueron tratadas en el Hospital Pediátrico Universitario William Soler, La Habana, Cuba. Resultados. En ambos casos el diagnóstico se apoyó en los estudios de imágenes, la laparoscopia y el análisis histopatológico. En un caso el tratamiento fue la hepatectomía derecha, mientras que en el otro se empleó la escleroterapia, ambas con evolución favorable. Conclusión. A pesar de su rareza, este diagnóstico no debe obviarse ante un paciente pediátrico con lesiones hepáticas quísticas. El tratamiento de elección es la resección quirúrgica, pero su indicación y envergadura debe valorarse de forma individualizada

Introduction. Cystic lymphatic malformations, also called cystic lymphangiomas, are very rarely found in the liver. Clinical cases. Two pediatric female preschool-age patients. presented with hepatomegaly due to multi-septated cystic lesions of the liver, who received treatment at Hospital Pediátrico Universitario William Soler, La Habana, Cuba. Results. We report two pediatric cases with giant cystic lymphatic malformation of the liver. In both cases, the diagnosis were based on imaging, laparoscopy and pathology. In one case the treatment was right hepatectomy, whereas in the other, sclerotherapy was performed, both with a favorable outcome. Conclusion. Despite its rarity, this diagnosis should be considered in pediatric patients with hepatic cystic lesions. The recommended treatment is surgical resection, but its indication and extent should be assessed individually for each patient.

Laparoscopic repair of bile duct injuries: Feasibility and outcomes.

INTRODUCTION: Bile duct injuries (BDI) following laparoscopic cholecystectomy occurs in approximately 0.6% of the cases, often being more severe and complex. Roux-en-Y hepaticojejunostomy (RYHJ) is considered the optimal therapeutic option, with success rates ranging from 75% to 98%. Several series have demonstrated the advancements of the laparoscopic approach for resolving this condition. The objective of this study is to describe our experience in the laparoscopic repair of BDI. METHODS: A retrospective, descriptive study was conducted, including patients who underwent laparoscopic repair after BDI. Demographic, clinical, surgical, and postoperative variables were analysed using descriptive statistical analyses. RESULTS: Eight patients with BDI underwent laparoscopic repair (out of 81 surgically repaired patients). Women comprised 75% of the sample. A complete laparoscopic repair was achieved in 75% (6) of cases. The mean age was 40.8 ± 16.61 years (range 19-65). Injuries at or above the confluence (Strasberg-Bismuth ≥ E3) occurred in 25% of cases (2). Primary repair was performed in two cases. Half of the cases underwent a Hepp-Couinaud laterolateral RYHJ, while three patients received a terminolateral RYHJ, and one underwent a bi-terminolateral RYH. The mean operative time was 260 min (range 120-360). Overall morbidity was 37.5% (3 cases): two minor complications (bile leak grade A and drainage-related bleeding) and one major complication (bile leak grade C). No mortality was recorded. The maximum follow-up period reached 26 months (range 6-26). CONCLUSIONS: Our study demonstrates the feasibility of laparoscopic RYHJ in a selected group of patients, offering the benefits of a minimally invasive approach.

Simulation in pediatric minimally invasive surgery: adaptation of a simple series of exercises as part of the process of an initial implementation of a resident training program / Simulação em cirurgia minimamente invasiva pediátrica: adaptação de uma série de exercícios simples e de fácil aplicação como parte do processo de implementação inicial de um programa de treinamento de residentes

ABSTRACT Introduction: the simulation in minimally invasive surgery is fundamental for surgeon in training to learning and training skills, especially in pediatrics, due to the particularities, reduced spaces, specific and rare procedures. The aim of this study was to propose an adapted series of exercises and to simply evaluate the performance of pediatric surgery residents in the initial implementation of a training program. Method: seven basic skills exercises in video surgery, based on series and programs already published and using low-cost materials, were performed by six residents in 2 moments, with an interval of 15 days and evaluated by simple instrument. Results: there was no difficulty with models. Considering the individual averages of the seven exercises together in the two moments, five of the six residents increased the score in the second moment. The average score per exercise increased in five of the seven tasks. Despite the small number of participants and repetition, it has already been possible to observe a trend of better performance with decreased time of all residents after a single repetition. All considered the exercises capable of training essential skills of the specialty, with simple and inexpensive materials. Conclusion: given the challenges of simulated training in pediatric video surgery, it is known the benefit of a continuous program, with exercises that can simulate real situations. A pre-established schedule, more participants and repetitions, supervision of experienced surgeons and validated instruments are fundamental to evaluate surgeons in training and show statistical benefits of simulated exercises in this series.

RESUMO Introdução: a simulação em cirurgia minimamente invasiva é fundamental para treinamento e aprendizagem de habilidades ao cirurgião em formação, especialmente na pediatria, devido às particularidades da especialidade, espaços reduzidos, procedimentos específicos e raros. O objetivo deste estudo foi propor uma adaptação de uma série de exercícios em simulador e avaliar o desempenho dos residentes de cirurgia pediátrica na implementação inicial de um programa de treinamento. Método: sete exercícios de habilidades básicas em videocirurgia, baseados em séries e programas já publicados e utilizando materiais de baixo custo, foram realizados por seis residentes em 2 momentos, com intervalo de 15 dias e avaliados por instrumento simples. Resultados: não houve dificuldade em relação aos modelos. Considerando- se as médias individuais dos sete exercícios juntos nos dois momentos, cinco dos seis residentes aumentaram a pontuação no segundo momento. A pontuação média por exercício aumentou em cinco das sete tarefas. Apesar do pequeno número de participantes e repetição, já foi possível observar uma tendência de melhor desempenho com diminuição do tempo de todos os residentes após uma única repetição. Todos consideraram os exercícios capazes de treinar habilidades essenciais da especialidade, de maneira acessível e com materiais simples e baratos. Conclusão: diante dos desafios do treinamento simulado em videocirurgia pediátrica, sabe-se do benefício de um programa contínuo, com exercícios que simulam situações reais. Um cronograma pré-estabelecido, mais participantes e mais repetições, supervisão de cirurgiões experientes e instrumentos validados são fundamentais para avaliar a evolução dos cirurgiões em formação e permitir demonstrar resultados com significância estatística.
