Complicated acute hiatal hernia after total gastrectomy / Hernia hiatal aguda complicada luego de gastrectomía total

Introduction. Surgery remains the mainstay of treatment for most esophagogastric junction (EGJ) tumors. After the surgical resection of EGJ tumors, the anatomy of the esophageal hiatus of the diaphragm is severely altered, increasing the risk of postoperative hiatal hernia (HH). While HH is more often reported after esophagectomy, HH is a rare complication after laparoscopic total gastrectomy and occurs in only approximately 0.5% of patients. Clinical case. A laparoscopic total gastrectomy with D2 lymphadenectomy was performed on a patient with an esophagogastric junction tumor. No intraoperative complications occurred and the patient had an uneventful postoperative course. Two months after the operation, the patient was admitted to the emergency room due to diffuse abdominal and chest pain, vomiting, and hematemesis. The chest and abdominal CT scan showed herniation of several bowel loops into the right hemithorax. Results. Due to hemodynamic instability, an emergent laparotomy was performed and the hiatal hernia was repaired with mesh. The patient recovered well from the operation and was discharged after 10 days. Conclusions. Clinical presentation is often non-specific and warrants a high level of suspicion. Elective surgical repair is recommended for large and/or symptomatic HH. Emergent repair might be needed for complicated HH with incarceration, strangulation, or bowel perforation. Overall, incarcerated HH after laparoscopic total gastrectomy is rare but should be considered in patients with abdominal pain or vomiting during the postoperative course. A prompt diagnosis and treatment are critical to obtain favorable outcomes.

Introducción. La cirugía sigue siendo el pilar del tratamiento para la mayoría de los tumores de la unión esofagogástrica (UEG). Después de la resección quirúrgica de los tumores de la UEG, la anatomía del hiato esofágico se altera severamente, aumentando el riesgo de hernia hiatal (HH) postoperatoria. Mientras que la HH se informa con mayor frecuencia después de la esofagectomía, la HH es una complicación rara después de una gastrectomía total laparoscópica y ocurre en solo aproximadamente 0,5 % de los pacientes. Caso clínico. Se realizó una gastrectomía total laparoscópica con linfadenectomía D2 en un paciente con un tumor en la UEG. No presentó complicaciones intraoperatorias y cursó su postoperatorio sin incidentes. Dos meses luego de la operación, fue admitido en la sala de emergencias debido a dolor abdominal y torácico difuso, vómitos y hematemesis. La tomografía computarizada de tórax y abdomen mostró herniación de asas intestinales en el hemitórax derecho. Resultados. Debido a la inestabilidad hemodinámica, se realizó una laparotomía de emergencia y se reparó la hernia hiatal con malla. El paciente fue dado de alta después de 10 días. Conclusiones. La presentación clínica suele ser inespecífica y justifica un alto nivel de sospecha. Se recomienda la reparación quirúrgica electiva para HH grandes y/o sintomáticas. La reparación de emergencia puede ser necesaria para HH complicadas con encarcelamiento, estrangulación o perforación intestinal. Generalmente, una HH encarcelada después de la gastrectomía total laparoscópica es infrecuente, pero debe considerarse en pacientes con dolor abdominal o vómitos durante el curso postoperatorio. Un diagnóstico y tratamiento oportunos son críticos para obtener resultados favorables.

Complicaciones quirúrgicas: un tema complicado / Surgical complications: A complicated topic

Introducción. Las complicaciones quirúrgicas son un tema relevante, difícil de abordar e inmerso en una cultura punitiva y vergonzosa hacia el médico. La ausencia de una medición sistemática, confiable y socializada es un desafío para los servicios quirúrgicos. El desconocimiento de las medidas de frecuencia y el impacto de las complicaciones quirúrgicas en las instituciones, y a su vez, dentro de los servicios quirúrgicos, evidencia la necesidad de abordar el tema desde una perspectiva de mejoramiento continuo. Métodos. Se hizo un análisis crítico y reflexivo sobre la conceptualización de las complicaciones quirúrgicas, los avances en su proceso de evaluación y su utilidad como indicador de calidad en los servicios quirúrgicos. Se ilustraron las metodologías con ejemplos clínicos que facilitan su entendimiento y aplicabilidad. Resultados. El trabajo inicial de los doctores Clavien & Dindo se ha fortalecido al considerar integralmente el proceso de atención quirúrgica como un indicador de calidad de la atención en salud. El desarrollo del Índice Integral de Complicaciones (CCI), para los eventos en el período posoperatorio, representa un paso adicional en el abordaje del problema. Su potencialidad en el análisis de los eventos ofrece una oportunidad para la implementación y la investigación en el tema. Conclusiones. Las complicaciones quirúrgicas representan un indicador robusto que permite evaluar el desempeño individual y grupal en un servicio quirúrgico. Hay metodologías recientes que deben ser incorporadas en la actividad asistencial de los cirujanos. Representan un insumo en la educación médica a todo nivel e, igualmente, un elemento de crecimiento personal y académico para todo cirujano.

Introduction. Surgical complications are a relevant topic, difficult to address and immersed in a punitive and shameful culture towards the doctor. The absence of systematic, reliable, and socialized measurement is a challenge for surgical services. The lack of knowledge of frequency measurements and the impact of surgical complications in institutions, and in turn, within surgical services, shows the need to address the issue from a perspective of continuous improvement. Methods. A critical and reflective analysis was carried out on the conceptualization of surgical complications, the advances in their evaluation process and their usefulness as an indicator of quality in surgical services. The methodologies were illustrated with clinical examples that facilitate their understanding and applicability. Results. The initial work of doctors Clavien & Dindo has been strengthened by comprehensively considering the surgical care process as an indicator of quality of health care. The development of the Comprehensive Complication Index (CCI), for events in the postoperative period, represents an additional step in addressing the problem. Its potential in the analysis of events offers an opportunity for implementation and research on the topic. Conclusions. Surgical complications represent a robust indicator that allows evaluating individual and group performance in a surgical service. There are recent methodologies that must be incorporated into the care activity of surgeons. They represent an input in medical education at all levels and equally, an element of personal and academic growth for every surgeon.

Se incluyeron en total 82 pacientes trasplantados, con un predominio del sexo masculino 59,8 % (n=49); la principal indicación del trasplante fue el alcoholismo (21,9 %). Veinte pacientes presentaron complicaciones vasculares; la más frecuente fue trombosis de arteria hepática, en el 45 % (n=9). En tres de estos casos se requirió nuevo trasplante. Conclusión. Las complicaciones vasculares empeoran la evolución clínica postoperatoria de los pacientes y están relacionadas con alta morbimortalidad, por lo cual es crucial la valoración multidisciplinaria, el diagnóstico oportuno y la intervención temprana para disminuir los desenlaces fatales.

Introduction. Liver transplant is the treatment indicated for those liver diseases in which other therapeutic measures have already been exhausted, and it is a complex procedure. Post-surgical complications are related to high morbidity and mortality and can lead to fatal outcomes. Vascular complications are the ones with the highest mortality, so early detection and timely treatment are crucial. The objective of this study was to characterize patients who presented vascular complications after liver transplantation. Methods. Descriptive, retrospective study, with follow-up of patients undergoing liver transplant at the Fundación Cardiovascular, between 2013 and 2023, who presented vascular complications. The type of complication, risk factors and postsurgical outcomes were evaluated. Results. A total of 82 transplant patients were included, with a predominance of males with 59.8% (n=49); the main indication for transplant was alcoholism (21.9%). Twenty patients presented vascular complications; the most frequent was hepatic artery thrombosis 45% (n=9). In three of these cases a new transplant was required. Conclusion. Vascular complications worsen the postoperative clinical course of patients and are associated with high morbidity and mortality, which is why multidisciplinary assessment, diagnosis and early intervention are crucial to reduce fatal outcomes.

Assessing the prevalence of hypocalcemia after total thyroidectomy at a tertiary care hospital

Background: Thyroidectomy is a common surgical procedure for various thyroid disorders, but it often leads to complications such as hypocalcemia. Understanding the prevalence and predictors of hypocalcemia post-total thyroidectomy is crucial for improving patient outcomes. Methods: This prospective cross-sectional study was conducted at a tertiary care hospital with 100 patients undergoing thyroid surgery, including total thyroidectomy, completion thyroidectomy, and thyroidectomy with neck dissection. We analyzed the incidence of transient and permanent hypocalcemia, examining correlations with surgery type, demographic variables, and postoperative day of onset. Data were collected through patient records and postoperative follow-ups. Results: The study revealed that 30% of patients experienced hypocalcemia postoperatively. Hypocalcemia was most prevalent among patients undergoing thyroidectomy with neck dissection (58.33%), compared to those undergoing total thyroidectomy (18.18%) and completion thyroidectomy (40.00%). The majority of hypocalcemia cases (66.67%) occurred on the second postoperative day. Most hypocalcemia instances were transient (86.67%), with a smaller fraction being permanent (13.33%). Conclusions: Hypocalcemia remains a significant complication following thyroid surgery, particularly in surgeries involving neck dissection. Early identification and management of at-risk patients could mitigate the severity of this complication. Our findings underscore the importance of vigilant monitoring and tailored postoperative care to minimize the impact of hypocalcemia on patient recovery and quality of life.

Caracterización epidemiológica de pacientes con síndrome posterior a resección anterior baja de recto y aproximación de su relación con aspectos demográficos, patológicos y quirúrgicos, en un centro de referencia en Medellín, entre 2016-2022 / Epidemiological characterization of patients with post-low anterior rectal resection syndrome and approximation of its relationship with demographic, pathological, and surgical aspects, in a referral center in Medellin, between 2016-2022

Introducción. El cáncer colorrectal es uno de los tipos de cáncer más comunes y mortales a nivel mundial. Aunque los avances médicos han mejorado el manejo, la cirugía sigue siendo fundamental. La resección anterior baja (RAB) de recto ha ganado relevancia, a pesar de que puede llevar al síndrome de resección anterior baja de recto (LARS, por sus siglas en inglés), afectando la calidad de vida. Métodos. Estudio de corte transversal con intención analítica en un centro de referencia en Medellín, Colombia. Los pacientes con cáncer de recto sometidos a RAB entre enero de 2016 y diciembre de 2022 completaron el cuestionario LARS para evaluar disfunción intestinal. Se evaluaron factores relacionados con la presencia de LARS por medio de un análisis bivariado. Resultados. De 234 pacientes elegibles, 110 (47 %) respondieron la encuesta, predominantemente mujeres (58,2 %). La edad promedio fue 62 años. Dos tercios de los pacientes recibieron neoadyuvancia y el 69 % requirieron ileostomía. La prevalencia de LARS fue 47,3 %. El 80,9 % llevaban más de 12 meses desde la cirugía o el cierre del estoma. Factores estadísticamente significativos asociados a LARS fueron edad mayor de 65 años (p=0,03), estadío patológico avanzado (p=0,02) y requerimiento de estoma (p=0,03). Conclusiones. El LARS afecta a casi la mitad de los pacientes en diferentes etapas posquirúrgicas. El LARS scorees una herramienta práctica para evaluar la función intestinal en el seguimiento del paciente. La prevalencia y los factores de riesgo identificados contribuyen a la comprensión del impacto de la cirugía conservadora del esfínter en la calidad de vida de los pacientes.

Introduction. Colorectal cancer is one of the most common and deadly types of cancer worldwide, with a high incidence of rectal cancer. Although medical advances have improved management, surgery remains crucial. Low anterior resection of the rectum (LAR) has gained significance, despite its potential to lead to low anterior resection syndrome (LARS), affecting quality of life. Methods. A cross-sectional study with analytical intent was conducted at a referral center in Medellín, Colombia. Patients with rectal cancer who underwent LAR between January 2016 and December 2022 completed the LARS questionnaire to assess intestinal dysfunction. Factors related to the presence of LARS were analyzed using bivariate analysis. Results. Of 234 eligible patients, 110 (47%) responded, predominantly women (58.2%). The average age was 62 years. Two-thirds of patients received neoadjuvant therapy and 69% required ileostomy. The prevalence of LARS was 47.3%. 80.9% had been more than 12 months post-surgery or stoma closure. Statistically significant factors associated with LARS included age over 65 years (p=0.03), advanced pathological stage (p=0.02), and stoma requirement (p=0.03). Conclusions. LARS affects almost half of the patients in various post-surgical stages. The LARS score is a practical tool for assessing intestinal function in patient follow-up. The prevalence and risk factors identified contribute to the understanding of the impact of sphincter-conserving surgery on patients' quality of life.

Efecto de la implementación de las recomendaciones del protocolo de recuperación mejorada después de cirugía (ERAS) en cirugía colorrectal en un hospital de referencia del suroccidente colombiano / Effect of the implementation of Enhanced Recovery After Surgery (ERAS) protocol recommendations in colorectal surgery at a reference hospital in Southwestern Colombia

Introducción. La implementación del protocolo de recuperación mejorada después de cirugía (ERAS) ha demostrado mejorar los desenlaces en cirugía colorrectal. En Colombia su implementación es escasa y se tiene poca evidencia de sus beneficios. Por esa razón, el objetivo de este estudio fue evaluar el efecto de la implementación del protocolo ERAS en los pacientes sometidos a cirugía colorrectal en un hospital de referencia en el suroccidente colombiano. Métodos. Estudio observacional con abordaje de emulación de experimento clínico ideal. Se incluyeron pacientes adultos sometidos a cirugía colorrectal mayor entre los años 2021 y 2023. Se midió días de estancia hospitalaria, ingreso a unidad de cuidado intensivo (UCI) y la presencia de complicaciones globales, reintervenciones o reingreso hospitalario a 30 días. Se realizó un análisis univariado y multivariado para medir el efecto de la implementación del protocolo ERAS en los desenlaces. Resultados. En total,132 pacientes cumplieron los criterios de inclusión, 79 pacientes en el período previo a la implementación de ERAS y 53 pacientes con el protocolo ERAS. En el análisis multivariado, se encontró una reducción relativa del 77 % para ingreso a UCI, del 57 % de complicaciones globales, del 67 % en el reingreso hospitalario y del 92 % para reintervenciones quirúrgicas tras el alta en los pacientes ERAS. Conclusiones. La implementación de las recomendaciones ERAS en nuestra institución demostró mejorar los resultados clínicos en pacientes sometidos a cirugía colorrectal mayor. En Colombia, se necesita de estudios multicéntricos que permitan evidenciar la plausibilidad y beneficios de estas recomendaciones en otras instituciones.

Introduction. Implementation of the Enhanced Recovery After Surgery (ERAS) protocol has been shown to improve outcomes in colorectal surgery. In Colombia, its implementation is scarce and there is limited evidence of its benefits. For this reason, the objective of this study was to evaluate the effect of ERAS protocol implementation in patients undergoing colorectal surgery in a reference hospital in Southwestern Colombia. Methods. Observational study with ideal clinical experiment emulation approach. Adult patients undergoing major colorectal surgery between 2021 and 2023 were included. Days of hospital stay, admission to the intensive care unit (ICU), and the presence of overall complications, reinterventions, or hospital readmission within 30 days were measured. A univariate and multivariate analysis was performed to measure the effect of the implementation of the ERAS protocol on the outcomes. Results. A total of 132 patients met the inclusion criteria, 79 patients in the period prior to ERAS implementation and 53 patients with the ERAS protocol. In the multivariate analysis, a relative reduction of 77% for ICU admissions, 57% for overall complications, 67% for hospital readmission, and 92% for surgical reinterventions after discharge in ERAS patients was found. Conclusions. Implementation of ERAS recommendations at our institution was shown to improve clinical outcomes in patients undergoing major colorectal surgery, In Colombia, multicenter studies are needed to demonstrate the plausibility and benefits of these recommendations in other institutions.

Reconstrução mamária: Experiência de 10 anos / Breast reconstruction: 10 years experience

Introdução: A reconstrução mamária pós-tratamento cirúrgico do câncer de mama (um dos principais cânceres que acometem as mulheres) tem sido progressivamente mais indicada, haja vista o benefício da recuperação psicológica e da qualidade de vida, seja utilizando implantes e/ou tecidos autólogos. O presente trabalho visa demonstrar a experiência da equipe, discutir técnicas operatórias e complicações em relação aos dados da literatura mundial, além de verificar a aplicabilidade da técnica na prática clínica da equipe. Método: Estudo observacional retrospectivo desenvolvido em hospital universitário em Juiz de Fora a partir da revisão de prontuários de pacientes submetidas a mastectomia com reconstrução mamária entre 2010 e 2020. Resultados: Das 860 mamas abordadas, 84% foram imediatas à cirurgia oncológica e 16% foram tardias; o principal acesso ao tecido mamário foi a incisão de Stewart, seguido de incisões inframamárias estendidas, periareolares e T invertido; quanto às técnicas reconstrutoras, destaca-se 35% dos casos com retalho com músculo grande dorsal, 25% com prótese pré-peitoral, 20% com retalho miocutâneo transverso do músculo reto abdominal e 10% com retalho muscular local. As complicações mais incidentes foram deiscência de sítio cirúrgico, seguida de necrose cutânea, seroma, infecção de sítio cirúrgico e hematoma, além de outros menos comuns como dor crônica e ruptura de prótese após mamografia. Conclusão: A reconstrução mamária pós-mastectomia é indispensável para a recuperação física e emocional da mulher, sendo as técnicas utilizadas nos últimos dez anos consistentes, confiáveis, de baixa morbidade e com ótimos resultados estéticos quando bem indicadas.

Introduction: Breast reconstruction after surgical treatment for breast cancer (one of the main cancers that affect women) has been progressively more recommended, given the benefits of psychological recovery and quality of life, whether using implants and/or autologous tissues. The present work aims to demonstrate the team's experience, and discuss operative techniques and complications concerning data from the world literature, in addition to verifying the applicability of the technique in the team's clinical practice. Method: Retrospective observational study developed at a university hospital in Juiz de Fora based on a review of medical records of patients who underwent mastectomy with breast reconstruction between 2010 and 2020. Results: Of the 860 breasts treated, 84% underwent immediate oncological surgery and 16% were late; the main access to the breast tissue was the Stewart incision, followed by extended inframammary, periareolar, and inverted T incisions; regarding reconstructive techniques, 35% of cases used a latissimus dorsi muscle flap, 25% used a prepectoral prosthesis, 20% used a transverse rectus abdominis myocutaneous flap and 10% used a local muscle flap. The most common complications were surgical site dehiscence, followed by skin necrosis, seroma, surgical site infection, and hematoma, in addition to other less common complications such as chronic pain and prosthesis rupture after mammography. Conclusion: Postmastectomy breast reconstruction is essential for a woman's physical and emotional recovery, with the techniques used in the last ten years being consistent, reliable, with low morbidity, and with excellent aesthetic results when correctly indicated.

Incidência de complicações durante os anos iniciais de formação de um serviço de fissuras labiopalatinas / Incidence of complications during the initial years of formation of a cleft lip and palate service

Introdução: A fissura labiopalatina é a malformação congênita craniofacial mais comum. Dificuldades na alimentação, fala e audição são comuns nestes pacientes, necessitando de tratamento multidisciplinar, o que dificulta a criação e manutenção de serviços especializados. A diversidade de classificações e o grande número de técnicas cirúrgicas utilizadas nas cirurgias primárias (queiloplastia e palatoplastia) dificultam a comparação de dados epidemiológicos e de complicações entre os serviços, existindo carência de estudos avaliando centros especializados em fissuras labiopalatinas recém-criados. Método: Foi realizado estudo do tipo coorte prospectiva com pacientes com diagnóstico de fissura labiopalatina submetidos a procedimentos cirúrgicos primários, no Hospital de Clínicas da Universidade Federal de Uberlândia, entre julho de 2017 e fevereiro de 2023. Foram incluídos pacientes menores de 18 anos com acompanhamento pós-operatório de pelo menos 3 meses. Resultados: Participaram do estudo 79 pacientes, que foram submetidos a 115 cirurgias primárias (54 queiloplastias e 61 palatoplastias). Foram relatadas 11 complicações neste período: 2 deiscências em queiloplastia (3,70%), 1 cicatriz hipertrófica em queiloplastia (1,85%), 6 fístulas em palatoplastia (9,83%) e 2 deiscências em palatoplastia (3,28%). A incidência de complicações foi de 9,56% quando analisado o total de cirurgias, sendo 5,55% nos pacientes submetidos a queiloplastia e 13,11% nos pacientes submetidos a palatoplastia. Conclusão: A incidência de complicações durante os anos iniciais de estruturação do serviço foi semelhante a outros estudos da literatura.

Introduction: Cleft lip and palate is the most common congenital craniofacial malformation. Difficulties in eating, speaking, and hearing are common in these patients, requiring multidisciplinary treatment, which makes it difficult to create and maintain specialized services. The diversity of classifications and the large number of surgical techniques used in primary surgeries (cheiloplasty and palatoplasty) make it difficult to compare epidemiological data and complications between services, and there is a lack of studies evaluating newly created specialized centers for cleft lip and palate. Method: A prospective cohort study was carried out with patients diagnosed with cleft lip and palate who underwent primary surgical procedures at the Hospital de Clínicas of the Universidade Federal de Uberlândia, between July 2017 and February 2023. Patients under 18 years of age with follow-up were included. post-operative period of at least 3 months. Results: 79 patients participated in the study, who underwent 115 primary surgeries (54 cheiloplasties and 61 palatoplasties). 11 complications were reported in this period: 2 dehiscences in cheiloplasty (3.70%), 1 hypertrophic scar in cheiloplasty (1.85%), 6 fistulas in palatoplasty (9.83%) and 2 dehiscences in palatoplasty (3.28%). The incidence of complications was 9.56% when analyzing the total number of surgeries, being 5.55% in patients undergoing cheiloplasty and 13.11% in patients undergoing palatoplasty. Conclusion: The incidence of complications during the initial years of structuring the service was similar to other studies in the literature.

Construction of a Perioperative Care Protocol for Individuals with Intestinal Ostomies / Construção de protocolo de assistência perioperatória destinado às pessoas com estomia intestinal / Certificación de un protocolo de asistencia perioperatoria para personas con estomías intestinales

Objective: To develop a nursing protocol to guide perioperative care for individuals with intestinal ostomies. Method: A methodological study conducted between March and June 2022, using a quantitative approach. The study was divided into three stages: 1) an exploratory phase to determine the characteristics of the target population using a questionnaire; 2) the definition of perioperative recommendations based on Enhanced Recovery After Surgery® (ERAS); and 3) the creation of the protocol. Data analysis involved simple descriptive statistics. Results: Ten (10) patients responded preoperatively, while only six (6) responded postoperatively. Preoperative education was provided by nurses in 50% of cases. Findings showed an absence of ostomy site marking in 90% of cases, insufficient self-care in 60%, and postoperative complications in 60%, including edema, mucocutaneous separation, contact dermatitis, peristomal hernia, edge maceration, and granuloma. The proposed protocol consists of a care flowchart with four lines of follow-up within the institution and a consolidated framework with four key axes of perioperative nursing actions. Each axis includes sub-axes that detail specific guidelines to be implemented. Conclusion: The situational analysis of the target population and perioperative complications demonstrated the feasibility of developing a perioperative care protocol focused on the immediate preoperative, intraoperative, and postoperative phases.

Comparison of the Functional Outcomes of Arthroscopic Anterior Cruciate Ligament Reconstruction through the All-inside and Outside-in Techniques: A Double-Blinded Randomized Controlled Trial / Comparação dos resultados funcionais da reconstrução artroscópica do ligamento cruzado anterior pelas técnicas all-inside e outside-in: Um ensaio clínico controlado, randomizado e duplo-cego

Abstract Objective To compare the functional outcomes of anterior cruciate ligament (ACL) reconstruction with hamstring autograft (HA) through the all-inside (AI) technique with adjustable-loop cortical Endobutton (Smith & Nephew, Watford, Hertfordshire, England) on the sides of the femur and tibia and through the outside-in (OI) technique using an interference screw on the tibial side and a cortical Endobutton on the femoral side. Materials and Methods The present is a double-blinded randomized controlled trial (RCT) of 44 patients undergoing arthroscopic ACL reconstruction from February 2019 to February 2022 in a tertiary care hospital. As per computer-based randomization, the patients were distributed into two groups: the AI and OI groups. Both groups were evaluated for 12 months using the Visual Analog Scale (VAS), the Lysholm Knee Scoring Scale, and part I (pain score) and part II (function score) of the Knee Society Score (KSS). Results On postoperative day 2,the VAS score was significantly higher in the OI group (p = 0.0001), but insignificant (p = 0.807) at 6 weeks. At 3, 6, and 12 months of follow-up, the score on the Lysholm Knee Scoring Scale was significantly higher (p = 0.001) in the AI group. At 6 months, both parts of the KSS showed a significant difference, with the AI group presenting a better outcome (p = 0.04). However, at 12 months, the AI group presented a better score on part I of the KSS, but no differences were observed regarding part II. Conclusion In a follow-up of 12 months, the patients submitted to the AI technique presented better outcome scores and pain relief than those submitted to the OI technique.

Resumo Objetivo Comparar os resultados funcionais da reconstrução do ligamento cruzado anterior (LCA) com autoenxerto de isquiotibiais pela técnica all-inside (AI) com Endobutton (Smith & Nephew, Watford, Hertfordshire, Inglaterra) cortical de alça ajustável nos lados do fêmur e da tíbia e pela técnica outside-in (OI) com parafuso de interferência no lado tibial e Endobutton cortical no lado femoral. Métodos Trata-se de um ensaio clínico controlado, randomizado e duplo-cego com 44 pacientes submetidos à reconstrução artroscópica do LCA de fevereiro de 2019 a fevereiro de 2022 em um hospital de cuidados terciários. De acordo com a randomização por computador, os pacientes foram distribuídos em dois grupos: AI e OI. Ambos os grupos foram avaliados durante 12 meses pela Escala Visual Analógica (EVA), a Escala de Pontuação do Joelho de Lysholm e pela parte I (pontuação de dor) e a parte II (pontuação de função) da escala Knee Society Score (KSS). Resultados No segundo dia de pós-operatório, a pontuação média na EVA foi significativamente maior no grupo OI (p = 0,0001), mas insignificante (p 0,807) às 6 semanas. Aos 3, 6 e 12 meses de acompanhamento, a pontuação na Escala de Lysholm (p = 0,001) foi significativamente maior no grupo AI. Aos 6 meses, ambas as partes da KSS apresentam uma diferença significativa, com o grupo AI apresentando um desfecho melhor (p = 0,04). No entanto, aos 12 meses, o grupo AI apresentou uma pontuação melhor na parte I da KSS, mas não foram observadas diferenças na parte II. Conclusão Em um acompanhamento de 12 meses, os pacientes submetidos à técnica AI apresentaram melhores pontuações de desfecho e alívio da dor do que aqueles submetidos à técnica OI.

Tomografía computarizada en el posoperatorio de cirugía abdominal mayor / Computed tomography scan after major abdominal surgery

RESUMEN Antecedentes: las cirugías abdominales mayores pueden presentar complicaciones posoperatorias graves cuya detección temprana resulta importante para su tratamiento. Objetivo: determinar la utilidad del uso de la tomografía computarizada (TC) para el diagnóstico temprano de las complicaciones de cirugía abdominal mayor. Materiales y métodos: estudio retrospectivo observacional descriptivo, mediante revisión de historias clínicas de pacientes operados de cirugía abdominal mayor en un Hospital Privado. Se agruparon los pacientes según presentaban o no síntomas sospechosos de complicación posoperatoria. Los primeros se clasificaron en 3 grupos: sin TC, con TC con hallazgos positivos y con TC sin hallazgos patológicos. Resultados: se analizaron 154 pacientes, con un promedio de edad de 61,3 ± 12,5 años; 83 (54%) fueron varones. Sobre 48 pacientes (31%) con síntomas sospechosos de complicaciones, fueron reoperados 6 sin TC, pero con síntomas muy evidentes, 7 con signos tomográficos positivos y 14/41 del grupo con TC negativa. Todos tuvieron hallazgos que justificaron la intervención. Hubo 27 casos (17,5%) con complicaciones IIIb según Clavien-Dindo y 3 pacientes (2%) fallecieron. Conclusión: la tomografía computarizada tuvo valor para confirmar una complicación, pero no para descartarla. Los parámetros clínicos cobran especial importancia en los pacientes sintomáticos sin hallazgos patológicos en la TC posoperatoria.

ABSTRACT Background: Major abdominal surgeries may present serious postoperative complications that require early diagnosis. Objective: The aim of this study was to determine the usefulness of computed tomography (CT) for the early diagnosis of major abdominal surgery complications. Material and methods: We conducted a retrospective, observational and descriptive study using data obtained from the medical records of patients undergoing major abdominal surgery in a private hospital. Patients were divided into two groups according to the presence or absence of symptoms suggesting a postoperative complication. Patients with symptoms were classified into 3 groups: without CT, with CT with positive findings and with CT without abnormal findings. Results: A total of 154 patients were analyzed; mean age was 61.3 ± 12.5 years and 83 (54%) were male. Of 48 patients (31%) with symptoms suggestive of complications, 6 had very evident symptoms and were re-operated without CT, 7 had positive findings on CT and CT was negative in 14/41. All the patients had findings that supported the decision to re-operate. There were 27 cases (17.5%) with grade 3b complications of the Clavien-Dindo classification and 3 patients (2%) died. Conclusion: Computed tomography was useful to confirm a complication, but not to rule it out. Clinical parameters remain of utmost importance in patients with symptoms and absence of abnormal findings in post-operative CT.

Fatores Associados aos Custos do Tratamento no Primeiro Ano após Implantes Iniciais ou Trocas de Geradores de Pulsos de Marca-passos Cardíacos / Factors Associated with the Treatment Costs within the First Year after Pacemaker Implantation or Pulse Generator Replacement

Resumo Fundamento O uso de marca-passos cardíacos artificiais tem crescido constantemente, acompanhando o envelhecimento populacional. Objetivos Determinar as taxas de readmissões hospitalares e complicações após implante de marca-passo ou troca de gerador de pulsos e avaliar o impacto desses eventos nos custos anuais do tratamento sob a perspectiva do Sistema Único de Saúde (SUS). Métodos Registro prospectivo, com dados derivados da prática clínica assistencial, coletados na hospitalização índice e durante os primeiros 12 meses após o procedimento cirúrgico. O custo da hospitalização índice, do procedimento e do seguimento clínico foram estimados de acordo com os valores reembolsados pelo SUS e analisados ao nível do paciente. Modelos lineares generalizados foram utilizados para estudar fatores associados ao custo total anual do tratamento, adotando-se um nível de significância de 5%. Resultados No total, 1.223 pacientes consecutivos foram submetidos a implante inicial (n= 634) ou troca do gerador de pulsos (n= 589). Foram observados 70 episódios de complicação em 63 pacientes (5,1%). A incidência de readmissões hospitalares em um ano foi de 16,4% (IC 95% 13,7% - 19,6%) após implantes iniciais e 10,6% (IC 95% 8,3% - 13,4%) após trocas de geradores. Doença renal crônica, histórico de acidente vascular encefálico, tempo de permanência hospitalar, necessidade de cuidados intensivos pós-operatórios, complicações e readmissões hospitalares mostraram um impacto significativo sobre o custo anual total do tratamento. Conclusões Os resultados confirmam a influência da idade, comorbidades, complicações pós-operatórias e readmissões hospitalares como fatores associados ao incremento do custo total anual do tratamento de pacientes com marca-passo.

Abstract Background The use of artificial cardiac pacemakers has grown steadily in line with the aging population. Objectives To determine the rates of hospital readmissions and complications after pacemaker implantation or pulse generator replacement and to assess the impact of these events on annual treatment costs from the perspective of the Unified Health System (SUS). Methods A prospective registry, with data derived from clinical practice, collected during index hospitalization and during the first 12 months after the surgical procedure. The cost of index hospitalization, the procedure, and clinical follow-up were estimated according to the values reimbursed by SUS and analyzed at the patient level. Generalized linear models were used to study factors associated with the total annual treatment cost, adopting a significance level of 5%. Results A total of 1,223 consecutive patients underwent initial implantation (n=634) or pulse generator replacement (n=589). Seventy episodes of complication were observed in 63 patients (5.1%). The incidence of hospital readmissions within one year was 16.4% (95% CI 13.7% - 19.6%) after initial implants and 10.6% (95% CI 8.3% - 13.4%) after generator replacements. Chronic kidney disease, history of stroke, length of hospital stays, need for postoperative intensive care, complications, and hospital readmissions showed a significant impact on the total annual treatment cost. Conclusions The results confirm the influence of age, comorbidities, postoperative complications, and hospital readmissions as factors associated with increased total annual treatment cost for patients with pacemakers.

Estado nutricional preoperatorio y complicaciones en cirugía digestiva oncológica: un estudio retrospectivo en un centro de cáncer chileno

Introducción: La desnutrición es una condición frecuente en pacientes oncológicos y puede estar presente en un 40-80% de éstos. En cirugía gastrointestinal, es ampliamente conocida la relación entre la desnutrición preoperatoria y las complicaciones. El objetivo de este estudio es conocer la asociación entre el estado nutricional preoperatorio según el índice de masa corporal (IMC), la valoración global subjetiva (VGS) y la frecuencia de complicaciones postoperatorias en pacientes sometidos a cirugía oncodigestiva electiva. Metodología: Estudio observacional de cohorte retrospectiva. Se incluyeron pacientes sometidos a cirugía digestiva entre abril de 2019 y abril de 2020. Se excluyeron aquellos pacientes con enfermedad fuera de alcance terapéutico curativo. Los pacientes fueron categorizados según el tipo de cáncer, la cirugía realizada, el tratamiento neoadyuvante, los parámetros nutricionales (IMC y VGS) y la albumina preoperatoria. Se registraron las complicaciones postoperatorias de acuerdo con la clasificación de Clavien-Dindo (III-V). Resultados: Se incluyeron 201 pacientes sometidos a cirugía digestiva. El 83,6% calificó en la categoría B o C según VGS. Diecinueve pacientes (9,5%) presentaron complicaciones postoperatorias. Tener una VGS de categoría C se asoció con un mayor riesgo de complicaciones postoperatorias. Otras variables significativas para desarrollar complicaciones fueron recibir tratamiento neoadyuvante combinado (QT + RT) y ser intervenido por una cirugía de alto riesgo nutricional. Conclusión: Tener un estado nutricional deteriorado previo a una cirugía oncológica según VGS, someterse a una cirugía de alto riesgo nutricional y/o someterse a un tratamiento neoadyuvante combinado presentan un mayor riesgo de desarrollar complicaciones postoperatorias. Se destaca la importancia de incorporar protocolos de evaluación y soporte nutricional como parte del tratamiento multimodal impartido desde el diagnóstico oncológico.

Introduction: Malnutrition is a frequent condition in cancer patients and may be present in 40-80% of them. In gastrointestinal surgery, the relationship between preoperative malnutrition and complications has been widely studied, due to the increased risk of postoperative complications. The aim of this study is to determine the association between preoperative nutritional status, according to body mass index (BMI), subjective global assessment (SGA) and the frequency of postoperative complications in patients undergoing elective oncological digestive surgery. Methodology: Observational retrospective cohort study. Patients undergoing elective surgery between April 2019 and April 2020 were included. Patients with disease outside the curative therapeutic scope were excluded. Patients were categorized by type of cancer, surgery performed, neoadjuvant treatment, nutritional parameters (BMI and SGA) and albumin prior to surgery. Postoperative complications were recorded according to the Clavien-Dindo classification (III-V). Results: A total of 201 patients undergoing digestive surgery were included. 83.6% qualified in category B or C according to VGS. Nineteen patients (9.5%) presented postoperative complications. Having a SGA category C is associated with a higher risk of postoperative complications. Other significant variables for developing complications were receiving combined neoadjuvant treatment (CT + RT) and undergoing high nutritional risk surgery. Conclusion: Having a deteriorated nutritional status prior to oncological surgery according to SGA, undergoing high nutritional risk surgery, and/or undergoing combined neoadjuvant treatment significantly increases the risk of developing postoperative complications. The importance of incorporating nutritional assessment and support protocols as part of the multimodal treatment given to the patient from the moment of cancer diagnosis stands out.

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.

An epidemiological trend in surgical management of pelvis and acetabulum fractures at Indira Gandhi Institute of Medical Sciences level-1 trauma centre in Patna: a retrospective study

Background: Pelvic and acetabular fractures, principally resulting from high-energy trauma like motor vehicle accidents, are challenging orthopedic injuries that can lead to significant morbidity and functional impairment. Understanding their epidemiology, treatment, and outcomes is crucial for improving patient care. Methods: This retrospective cohort study involving 34 patients who underwent surgery for pelvic and acetabular fractures from April 2021 to September 2023. Data on patient demographics, injury mechanisms, fracture types, surgical approaches, and post-operative outcomes were collected and analyzed. Results: The study group comprised predominantly males (67%) with mean age of 35 years. Road traffic accidents were the leading cause of injuries (95%). The most common fracture types were the posterior wall of the acetabulum (10%) and type II anteroposterior compression fractures (10%). Related injuries included long bone fractures (62.5%) and posterior hip dislocation (33.33%). Surgical treatment primarily involved open reduction and internal fixation with various approaches. Postoperative complications included sciatic nerve palsy (4.17%), venous thromboembolism (20.83%), and wound infections (12.5%), but both post-operative mortality and heterotopic ossification were absent. Conclusions: The study highlights the prevalence of pelvic and acetabular fractures due to road traffic accidents and the complexity of their surgical management. The associated injuries and postoperative complications underscore the need for specialized orthopedic care.
