Recommendations from Annals of Surgical Oncology： Clinical guidelines for extrahepatic cholangiocarcinoma and gallbladder carcinoma / 临床肝胆病杂志

Biliary tract carcinoma （BTC） is a type of gastrointestinal tumor with a low incidence rate and a strong invasive ability， mainly including intrahepatic cholangiocarcinoma （ICC）， extrahepatic cholangiocarcinoma （ECC）， and gallbladder carcinoma （GC）， often accompanied by local progression or distant metastasis. Surgery is often the preferred treatment method for patients with local resectable tumor； however， there is still a high risk of recurrence after radical surgery. Therefore， multiple treatment modalities are often required for BTC patients， including surgical resection， systemic treatment （such as targeted therapy， chemotherapy， and immunotherapy）， and/or a combination of local treatment methods. With the development of the field of BTC， it is critical for surgical oncologists to understand and master the latest surgical strategies and the best patient selection and management systems. In view of the complexity of treatment and the continuous development of diagnosis and treatment techniques， Annals of Surgical Oncology， an authoritative American journal of cancer surgery， recently published the practical diagnosis and treatment guidelines for hepatobiliary tumors， including hepatocellular carcinoma （HCC）， ICC， ECC， and GC， aiming to provide more evidence-based evidence for the clinical management and decision-making of patients with hepatobiliary tumors. Due to the limitations of length and different emphases， this article mainly introduces the recommendations for the evaluation points and clinical treatment of ECC and GC in the guidelines， so as to provide a reference for clinical practice.

Early or Delay? The Most Suitable Rehabilitation Protocol for "No Man's Land" Injury: Meta-Analysis with Trial Sequential Analysis - 20 Years Trends / Precoce ou tardio? O protocolo de reabilitação mais adequado para lesão na região 'terra de ninguém': Metanálise com análise sequencial de ensaios - Tendências de 20 anos

Abstract Objective The aim of this study is to analyze various rehabilitation protocol and determine which methods will yield a better outcome. Methods The database reports were searched within 1990 until 2020, using PubMed, Cochrane library database, Ovid, Medline, and the other several published trials. A statistical analysis was made from Review Manager and Trial Sequential Analysis (TSA). Result The mean of re-rupture rate is 3.3% (n= 8) in the combination protocol until 8% (n= 48) in CAM protocol. Meta-analyses found no significant difference between Kleinert vs CAM in re-rupture rate. Also no significant difference in Duran vs CAM in rerupture rate. In Trial Sequential Analysis (TSA), the z-curve does not cross both of the trial sequential boundaries, a further trial with larger sample will be required. The TSA of flexion contracture CAM vs Kleinert was indicated that CAM protocol may be superior than Kleinert to reduce the incidence of flexion contracture. For the range of mean flexion contracture 6.6% (n= 18) in CAM to 23.6% (n= 76) in Kleinert protocol. Conclusion Current meta-analysis proposed that the combination technique will result less re-rupture incidence and better functional outcome in flexor zone II injuries than other techniques. The CAM method also results less flexion contracture than others. However, a further meta-analyses with larger sample trials will be required to confirm this review's conclusion.

Resumo Objetivo O objetivo deste estudo é analisar vários protocolos de reabilitação e determinar quais métodos produzem um melhor resultado. Métodos Os relatórios dos bancos de dados foram pesquisados entre 1990 e 2020, usando PubMed, banco de dados da biblioteca Cochrane, Ovid, Medline e vários outros ensaios publicados. Uma análise estatística foi feita a partir do Review Manager e Trial Sequential Analysis (TSA). Resultado A taxa média de re-ruptura é de 3,3% (n = 8) no protocolo combinado, e até 8% (n = 48) no protocolo de Movimento Ativo Controlado (MAC). As metanálises não encontraram diferença significativa entre Kleinert vs MAC na taxa de re-ruptura. Também não há diferença significativa entre Duran e MAC na taxa de re-ruptura. Na Trial Sequential Analysis (TSA), a curva z não cruza ambos os limites sequenciais de ensaio, será necessário um ensaio adicional com amostra maior. A TSA de contratura em flexão MAC vs Kleinert indicou que o protocolo MAC pode ser superior ao Kleinert para reduzir a incidência de contratura em flexão. Para a faixa de contratura média em flexão de 6,6% (n = 18) no MAC a 23,6% (n = 76) no protocolo Kleinert. Conclusão A metanálise atual propôs que a técnica combinada resultará em menor incidência de re-ruptura e melhor resultado funcional em lesões da zona flexora II do que outras técnicas. O método MAC também resulta em menos contratura em flexão do que outros. No entanto, serão necessárias mais metanálises com estudos com amostras maiores para confirmar a conclusão desta revisão.

Riesgo de accidente cerebrovascular en pacientes con aterosclerosis carotídea asintomática: ¿se debe tratar médicamente o quirúrgicamente?

Los desórdenes cerebrovasculares siguen siendo la primera causa de morbilidad y mortalidad neurológica en el mundo, representando una de las entidades patológicas que genera mayor carga de enfermedad a nivel global. La aterosclerosis, o estenosis carotídea, es un potencial factor de riesgo para el ictus isquémico. La identificación y seguimiento estricto de esta condición son esenciales en la prevención secundaria de complicaciones a través de la atención primaria y el manejo especializado del riesgo cardiometabólico. No obstante, dependiendo de este riesgo y/o la presencia de sintomatología, es necesario realizar un manejo definitivo. Actualmente, existe controversia sobre si es mejor tratar la estenosis carotídea asintomática, ya sea médica o quirúrgicamente. Teniendo en cuenta la relevancia de esta entidad, el objetivo de esta revisión consiste en analizar la evidencia reciente sobre el riesgo de ictus isquémico en la aterosclerosis carotídea asintomática en adultos, y el potencial beneficio del manejo quirúrgico vs. farmacológico de esta condición. Para esto, se llevó a cabo una búsqueda bibliográfica en las bases de datos PubMed, ScienceDirect, Web of Science y MEDLINE, hasta el año 2023. Se evidenció que el riesgo de ictus asociado a estenosis carotídea asintomática es significativo (>10 %, aproximadamente), incluso en aquellos con terapia antiplaquetaria e hipolipemiante activa. En aquellos con manejo médico, la supervivencia a cinco años es alrededor del 80 %. Sin embargo, la progresión de la estenosis sucede en promedio en más del 60 % de los casos, y es significativa. Por el contrario, el stent carotídeo y la endarterectomía son intervenciones resolutivas. Pero existe un riesgo mayor comparado con la terapia médica, el cual se atribuye al periodo periy posoperatorio, así como a 30 días de aparición o recurrencia del ictus, infarto agudo de miocardio o muerte por cualquier causa; aunque el uso de la endarterectomía ha demostrado beneficios superiores a largo plazo en cuanto a estos mismos desenlaces. Entonces, la evidencia es heterogénea en cuanto a la superioridad del tratamiento quirúrgico comparado con la terapia farmacológica en el manejo de la aterosclerosis o estenosis carotídea asintomática. Sin embargo, parece ser que el manejo quirúrgico, específicamente la endarterectomía, podría impactar significativamente sobre la aparición o recurrencia del ictus ipsilateral y muerte a largo plazo, pero con resultados controversiales periy postoperatorios.

Cerebrovascular disorders remain the leading cause of neurological morbidity and mortality in the world, representing one of the pathological entities responsible for the greatest burden of disease worldwide. Carotid atherosclerosis or stenosis is a potential risk factor for ischemic stroke. The identification and strict follow-up of this condition are essential in the secondary prevention of complications through primary care and the specialized treatment of cardiometabolic risk. However, depending on this risk and/or presence of symptoms, definitive treatment is necessary. Currently, there is controversy as to whether asymptomatic carotid stenosis is better to be treated medically or surgically. Considering the significance of such entity, this review aims to analyze recent evidence on the risk of ischemic stroke in the case of asymptomatic carotid atherosclerosis among adults, as well as the potential benefit of the surgical vs. pharmacological treatment for this condition. For this purpose, a literature search for publications up to 2023 was carried out in PubMed, ScienceDirect, Web of Science and MEDLINE databases. It was shown that there is a significant risk of stroke associated with asymptomatic carotid stenosis (> 10 % approximately), even in patients with active antiplatelet and lipid-lowering therapy. Out of all those who receive medical treatment, around 80 % had a five-year survival rate. However, stenosis progression occurs on average in more than 60 % of the cases and is significant. On the other hand, carotid stenting and endarterectomy are curative interventions. Nevertheless, these procedures involve a higher risk compared to the medical therapy during the periand postoperative period, as well as 30 days afterwards, due to the occurrence or recurrence of stroke, acute myocardial infarction or death from any cause. Despite this, the use of endarterectomy has shown superior long-term benefits concerning these same outcomes. Thus, evidence regarding the superiority of surgical treatment compared to pharmacological treatment for asymptomatic carotid atherosclerosis or stenosis is heterogeneous. However, it seems that surgical treatment, specifically endarterectomy, could have a significant impact on the occurrence or recurrence of ipsilateral stroke and death in the long term but with controversial periand postoperative outcomes.

Desenlaces negativos y mortalidad en el anciano frágil sometido a cirugía mayor: ¿qué factores de riesgo impactan más?

El adulto mayor, con frecuencia frágil, es un paciente susceptible a un sinnúmero de complicaciones, tanto inmediatas como a corto, mediano y largo plazo, posterior a una intervención quirúrgica. En función de las comorbilidades presentadas, se debe hacer un abordaje integral para alcanzar el mejor estado orgánico previo a la cirugía e intentar mantenerlo durante y posterior a la intervención. Considerar la fuerza estadística de los desenlaces negativos y, específicamente, de la mortalidad en adultos mayores sometidos a cirugía mayor, es verdaderamente un reto. Incluso, esto trasciende a otros campos como la bioética, al plantearse un dilema sobre la distanasia, cuando se recurre a ciertas intervenciones riesgosas en aquellos con un pronóstico de vida temeroso. Recientemente, se ha publicado evidencia interesante que ha estimado la incidencia, riesgo de mortalidad y factores asociados a desenlaces negativos en adultos mayores sometidos a cirugía mayor, planteando posibles modificaciones en los algoritmos de toma de decisiones en futuras guías de práctica clínica en cirugía. El objetivo de esta revisión consiste en analizar evidencia actualizada sobre qué factores de riesgo impactarían más sobre desenlaces negativos y mortalidad en el adulto mayor sometido a cirugía mayor. Se realizó una búsqueda bibliográfica utilizando los términos de búsqueda "Cirugía Mayor" y "Adulto Mayor", además de sinónimos, en las bases de datos PubMed, ScienceDirect, Web of Science y MEDLINE. En cirugía general y subespecialidades, es muy complejo determinar factores de riesgo precisos y extrapolables a todos los escenarios quirúrgicos, debido a la complejidad y especificidad de ciertos órganos y procedimientos. Existe evidencia sobre adultos frágiles que son sometidos a cirugía por cáncer colorrectal, metástasis hepática, cáncer de pulmón, enfermedad pancreática y cáncer esofágico, en donde se registra una mayor estancia hospitalaria; y de forma general, la mortalidad es mayor en aquellos sometidos a cirugía oncológica. No obstante, tanto la integridad física como mental se asocian con peores desenlaces, y la prehabilitación quirúrgica podría impactar de manera positiva sobre esta situación, al mejorar la reserva funcional y tiempo de recuperación posquirúrgico.

The elderly, often frail, are patients susceptible to numerous complications, both immediate and in the short, medium and long term, following surgical interventions. Depending on their comorbidities, a comprehensive approach should be taken to achieve the best condition of the organs prior to surgery and attempt to maintain it during and after the intervention. Considering the statistical strength of negative outcomes, specifically mortality in elderly patients undergoing major surgery, is truly a challenge. This even extends to other fields such as bioethics, raising a dilemma about dysthanasia when resorting to certain risky interventions in those with a fearful life prognosis. Recently, interesting evidence estimating the incidence, mortality risk and factors associated with negative outcomes in elderly patients undergoing major surgery has been published, suggesting possible modifications in decision-making algorithms for future clinical practice guidelines in surgery. The objective of this review is to analyze updated evidence on which risk factors would have the greatest impact on negative outcomes and mortality in elderly patients undergoing major surgery. A literature search was conducted using the search terms "Major Surgery" and "Elderly," in addition to synonyms, in the PubMed, ScienceDirect, Web of Science and MEDLINE databases. In general surgery and subspecialties, it is very complex to determine precise risk factors that can be extrapolated to all surgical scenarios due to the complexity and specificity of certain organs and procedures. Evidence has found that frail adults undergoing surgery for colorectal cancer, liver metastasis, lung cancer, pancreatic disease and esophageal cancer have the longest hospital stays, and overall mortality is higher in those undergoing oncologic surgery. However, both physical and mental integrity are associated with worse outcomes, and surgical prehabilitation could positively impact this situation by improving functional reserve and post-surgical recovery time.

The influence of 3D renal reconstruction on surgical planning for complex renal tumors: An interactive case-based survey

ABSTRACT Objectives To evaluate the role of three-dimensional (3D) reconstruction in preoperative planning for complex renal tumors. Materials and Methods A well-planned questionnaire was distributed among the attending urologists at an international meeting. The questionnaire inquired about demographic data, surgical experience, partial nephrectomy (PN) versus radical nephrectomy (RN), surgical approach, time of ischemia, probability of postoperative urine leakage and positive surgical margins after viewing computed tomography (CT) scans and their respective 3D models of six complex renal tumors. Following the CT scans, attendees were asked to view randomly selected reconstructions of the cases. Results One hundred expert urologists participated in the study; 61% were aged between 40 and 60 years. Most of them (74%) were consultants. The overall likelihood of PN after viewing the 3D reconstructions significantly increased (7.1±2.7 vs. 8.0±2.2, p<0.001), the probability of conversion to RN significantly decreased (4.3±2.8 vs. 3.2±2.5, p<0.001), and the likelihood of urine leakage and positive surgical margins significantly decreased (p<0.001). Preference for the open approach significantly decreased (21.2% vs. 12.1%, p<0.001), while selective clamping techniques significantly increased (p<0.001). After viewing the 3D models, low expected warm ischemia time and estimated blood loss were significantly preferred by the respondents (p<0.001). Surgical decision change was significantly associated with performance or participation in more than 20 PNs or RNs annually [3.25 (1.98-5.22) and 2.87 (1.43-3.87), respectively]. Conclusions 3D reconstruction models play a significant role in modifying surgeons' strategy and surgical planning for patients with renal tumors, especially for patients with stronger indications for a minimally invasive and/or nephron-sparing approach.

Outcomes of the Carlson Approach in the Treatment of Posterior Tibial Plateau Fractures / Resultados da abordagem de Carlson para o tratamento de fraturas no platô tibial posterior

Abstract Objectives To describe a series of cases of tibial fractures surgically treated using the posterior approach as described by Carlson, focusing on evaluating its functional results and complication rate. Methods Eleven patients with tibial plateau fractures, who underwent surgical treatment using the Carlson approach from July to December 2019, were followed-up. The minimum follow-up period was defined as 6 months. The American Knee Society Score (AKSS), American Knee Society Score/Function (AKSS/Function) and the Lysholm score were used to check treatment results at 6 months after the fracture. The patients underwent standard anteroposterior and lateral radiographs to assess fracture healing, and clinical healing was determined by the absence of pain during full weight-bearing. Results The mean follow-up period was 12 months (9-16 months). The primary mechanism of trauma was motorcycle accident, and the most prevalent side of fracture was the right side. Eight participants were male. The mean age of the patients was 28 years. All fractures healed, and none of the patients presented complications. The AKSS was excellent in 11 patients, with a mean AKSS/Function of 99.1±3, and Lysholm scores with a median of 95.0±5.6. Conclusions The Carlson approach for posterior fractures of the tibial plateau can be considered safe, presenting a low complication rate and satisfactory functional results.

Resumo Objetivos O objetivo deste trabalho é descrever uma série de casos de fraturas de tíbia submetidas ao tratamento cirúrgico pela via posterior de Carlson para avaliação de resultados funcionais e frequência de complicações. Métodos Onze pacientes com fraturas do platô tibial foram submetidos a tratamento cirúrgico pela via de Carlson de julho a dezembro de 2019 e acompanhados por um período mínimo de 6 meses. As pontuações American Knee Society Score (AKSS), American Knee Society Score/Function (AKSS/Função) e de Lysholm verificaram os resultados do tratamento 6 meses após a fratura. Os pacientes foram submetidos a radiografias comuns em incidência anteroposterior e de perfil para avaliação da consolidação da fratura e a cicatrização clínica foi determinada pela ausência de dor à descarga total de peso. Resultados O período médio de acompanhamento foi de 12 meses (9 a 16 meses). O principal mecanismo de trauma foi acidente motociclístico e a fratura foi mais prevalente no lado direito. Oito pacientes eram do sexo masculino. A média de idade dos pacientes foi de 28 anos. Todas as fraturas cicatrizaram e nenhum paciente apresentou complicações. A AKSS foi excelente em 11 pacientes, com AKSS/Função média de 99,1 ±3, e a mediana das pontuações de Lysholm foi de 95,0 ±5,6. Conclusões Nas fraturas posteriores do platô tibial, a abordagem de Carlson pode ser considerada segura, apresentando baixo índice de complicações e resultados funcionais satisfatórios.

Nursing Care Related with Surgical Position / Cuidados de enfermería relacionados con la posición quirúrgica / Cuidados de enfermagem relacionados à posição cirúrgica

The patient's correct position is necessary to conduct a safe and effective surgical procedure. This position depends on the access route, duration of the procedure, kind of anesthesia, devices to use, among other factors. This procedure requires planning and effort by the surgical team where they share responsibility to establish and maintain the correct positions for patients. Each surgical position fulfills an objective and implies risks to patients, which is why nursing professionals must be very attentive to provide the necessary care and ensure reliable practices in each position during the perioperative, the importance of the documentation, and the NANDA, NIC, and NOC taxonomy to consider.

La correcta posición del paciente es necesaria para el desarrollo de un procedimiento quirúrgico seguro y eficaz. Esta posición depende de la vía de acceso, la duración del procedimiento, el tipo de anestesia, los dispositivos a utilizar entre otros factores. Este procedimiento requiere planeación y esfuerzo del equipo quirúrgico donde se comparten responsabilidad para establecer y mantener las posiciones correctas para los pacientes. Cada posición quirúrgica cumple un objetivo e implica un riesgo para el paciente, por lo que los profesionales de enfermería deben estar muy atentos para brindar los cuidados necesarios y asegurar prácticas confiables en cada posición durante el perioperatorio, la importancia de la documentación y la taxonomía NANDA, NIC y NOC a tener en cuenta.

The academic impact of the symposium on endoscopy and minimally invasive spine surgery of the mexican association of spine surgeons - amcico / O impacto acadêmico do simpósio de endoscopia e cirurgia minimamente invasiva da coluna vertebral da associação mexicana de cirurgiões da coluna vertebral - amcico / El impacto académico del simposio de endoscopia y cirugía minimamente invasiva de columna de la asociación mexicana de cirujanos de columna - amcico

ABSTRACT Introduction: The interest in spinal endoscopy is rising, particularly among younger spine surgeons. Formalized postgraduate training programs for endoscopic spinal surgery techniques are lacking behind. Methods: The authors performed a retrospective survey study amongst participants of the 2022 AMCICO endoscopic surgery symposium. Descriptive and correlative statistics were done on the surgeon's responses recorded in multiple-choice questions. In addition, surgeons were asked about their clinical experience and preferences with spinal endoscopy, training background, the types of lumbar endoscopic decompression they perform by approach, and future training requirements. SPSS (version 27) statistical software package was used for data analysis. Descriptive statistic measures were used to count responses and calculate the mean, range, standard deviation, and percentages. In addition, chi-square statistics were used to determine the strength of the association between factors. Results: The online survey was accessed by 321 surgeons, of which 92 completed it (53.4%). Demographic data showed the majority of responding surgeons being orthopedic surgeons (73.6%) and under the age of 50 (69.2%), with over half (51.1%) having less than three months of formalized training in endoscopic spinal surgery techniques. Most surgeons practiced uni-portal (58.9%) versus bi-portal (3.4%) spinal endoscopy. The transforaminal approach (65.5%) was preferred over the interlaminar method (34.4%). The bi-portal technique was indicated almost exclusively for the lumbar spine (94.8%). For endoscopically assisted spinal fusions, a uni-portal approach was preferred by 72% of surgeons over a bi-portal procedure (24.5%). 84.1% of respondents were interested in navigation, of which 30.7% preferred optical over electromagnetic technology (18.2%). Robotics was of interest to 51.1% of survey participants. Respondents' bias was estimated with course attendance assessments, with 37% of surgeons having attended all three days, 27.2% two days, and 16.3% one day. One-fifth of responding spine surgeons did not participate in any curriculum activities but completed the survey. The academic impact of the AMCICO endoscopy symposium was high, with 68.1% of respondents indicating interest in continued training and 61.1% of trainees ready to apply their newly acquired knowledge base to clinical practice. Conclusion: The interest in spinal endoscopy surgery techniques and protocols is high among AMCICO members. Many surgeons are interested in learning advanced endoscopic surgical techniques to integrate the technology into their surgical procedure portfolio to address common painful conditions of the degenerative spine beyond herniated discs and foraminal stenosis. The authors concluded that its academic impact was high based on the responses given by the participating surgeons. Level of evidence III; Retrospective study.

Resumo: Introdução: O interesse em cirurgia endoscópica da coluna tem aumentado especialmente entre os jovens cirurgiões, contudo, são poucos os centros que atualmente oferecem programas de treinamento nesta disciplina. Métodos: Foi realizada uma pesquisa retrospectiva entre os participantes do simpósio de "Cirurgia Minimamente Invasiva e Endoscópica da Coluna Vertebral" realizado durante o Congresso AMCICO 2022. Estatísticas descritivas e testes de correlação foram aplicados às respostas das perguntas de múltipla escolha. Os cirurgiões foram questionados sobre experiência clínica e preferências pela endoscopia espinhal, histórico de treinamento, tipos de descompressão lombar endoscópica que realizaram e requisitos futuros para um treinamento adicional. O software estatístico SPSS (versão 27) foi utilizado para a análise de dados. As medidas estatísticas descritivas foram utilizadas para quantificar as respostas e calcular a mediana, a média, o desvio padrão e as porcentagens. O qui-quadrado foi empregado para determinar a associação entre os fatores estudados. Resultados: A pesquisa on-line foi visualizada por 321 cirurgiões, dos quais 92 a completaram (53,4%). As informações demográficas mostraram que a maioria dos participantes são cirurgiões ortopédicos (73,6%) e menores de 50 anos (69,2%), com mais da metade deles (51,1%) possuindo menos de 3 meses de treinamento formal em técnicas endoscópicas. A maioria dos cirurgiões pratica abordagens uniportais (58,9%, contra 3,4% bi-portais). A abordagem transforaminal (65,5%) foi preferida em relação à abordagem interlaminar (34,4%). A abordagem biportal foi selecionada como a abordagem indicada para a região lombar (94,8%). Para a fusão endoscopia-assistida, a abordagem unilateral foi preferida por 72% dos participantes contra a abordagem biportal (24,5%). Os sistemas de navegação foram de interesse para 84,1% dos participantes, dos quais 30,7% responderam que preferiam a óptica em vez da eletromagnética (18,2%). O uso da robótica foi de interesse para 51,1% dos participantes. O viés dos participantes foi calculado com base no percentual de participação, onde 37% participaram de todos os 3 dias de conferências, 27,2% participaram de 2 dias e 16,3% participaram de apenas um dia. Um quinto dos cirurgiões não participaram das atividades do simpósio e ainda assim responderam à pesquisa. O impacto acadêmico do simpósio de "Cirurgia Minimamente Invasiva e Endoscópica da Coluna Vertebral" foi alto, com 68,1% dos participantes respondendo que têm interesse em treinamento adicional nestas técnicas e 61,1% respondendo que estão prontos para aplicar novos conhecimentos em sua prática médica. Conclusão: O interesse em técnicas cirúrgicas endoscópicas da coluna vertebral é alto entre os membros da AMCICO. Um grande número de cirurgiões está interessado em aprender técnicas cirúrgicas endoscópicas avançadas da coluna vertebral e integrar esta tecnologia como parte de suas ferramentas cirúrgicas para resolver problemas comuns que afetam a coluna com doença degenerativa, além de hérnias de disco e estenoses foraminais. Baseados nas respostas fornecidas pelos cirurgiões participantes, os autores concluem que o impacto acadêmico foi elevado. Nível de evidência III; Estudo retrospectivo.

Risk factors for pulmonary infection after laparoscopic surgery in treatment of hepatocellular carcinoma with liver cirrhosis and portal hypertension / 临床肝胆病杂志

Objective To investigate the incidence rate of pulmonary infection after laparoscopic surgery and related risk factors in patients with hepatocellular carcinoma (HCC) comorbid with liver cirrhosis and portal hypertension (PHT). Methods A retrospective analysis was performed for the clinical data of 105 HCC patients with liver cirrhosis and PHT who underwent laparoscopic surgery in Beijing Ditan Hospital, Capital Medical University, from January 2017 to February 2022. A total of 30 factors that might cause pulmonary infection were recorded, including general information, disease factors, surgical factors, and postoperative factors. Postoperative recovery was observed and the occurrence of pulmonary infection was recorded. The chi-square test or the Fisher's exact test was used for comparison of categorical data between two groups, and the multivariate logistic regression analysis was used to investigate the independent risk factors for pulmonary infection. Results Among the 105 patients, 66 underwent laparoscopic devascularization combined with hepatectomy and 39 underwent laparoscopic devascularization combined with radiofrequency ablation (RFA). The surgery was successful for all patients, with no case of conversion to laparotomy or unscheduled reoperation. No death was observed within 30 days after surgery and during hospitalization, with a median length of hospital stay of 20 days (range 14-25 days). The incidence rate of pulmonary infection was 25.71% (27/105). Smoking (odds ratio [ OR ]=3.362, 95% confidence interval [ CI ]: 1.282-8.817, P =0.014), MELD score ( OR =3.801, 95% CI : 1.007-14.351, P =0.049), tumor location ( OR =1.937, 95% CI : 1.169-3.211, P =0.010), surgical procedure ( OR =0.006, 95% CI : 0.001-0.064, P =0.000), intraoperative infusion volume ( OR =4.871, 95% CI : 1.211-19.597, P =0.026), and postoperative pleural effusion ( OR =9.790, 95% CI : 1.826-52.480, P =0.008) were independent risk factors for pulmonary infection. Conclusion There is a relatively high risk of pulmonary infection in HCC patients with liver cirrhosis and PHT undergoing laparoscopic surgery. Postoperative pleural effusion is the high risk factor for pulmonary infection, and devascularization combined with RFA can significantly reduce the risk of pulmonary infection. It is recommended to strengthen preoperative rehabilitation, perioperative liver function maintenance, intraoperative damage control, and goal-oriented fluid therapy and reduce postoperative fluid accumulation in the third space, so as to reduce the incidence rate of pulmonary infection.

Da-vinci robot-assisted surgery vs laparoscopic repair for the treatment of hiatal hernia repair / 中华普通外科杂志

Objective:To compare Da-vinci robotic surgical system with laparoscopic surgery for the repair of hiatal hernia.Methods:The clinical data of 115 patients undergoing minimally invasive Nissen fundoplication at the Department of Hernia and Abdominal Wall Surgery, the Affiliated Hospital,Xuzhou Medical University from Dec 2019 to May 2022 were retrospectively studied. After propensity score matching (PSM), 46 cases in each group were included:Robot-assisted surgery (RS group) and laparoscopic surgery (LS group). Postoperative complications were collected and GERD Questionnaire (GERDQ) were used as the standard in evaluation of the results.Results:Patients in RS group had less intraoperative bleeding ( P<0.001), shorter postoperative gastrointestinal recovery time ( P<0.001), and shorter postoperative hospital stay ( P=0.002). The LS group had a shorter operative time ( P<0.001) and lower total hospital cost ( P<0.001). GERD-Q scores decreased significantly in both groups at 3 and 6 months postoperatively compared with preoperative scores ( P<0.001). There was no statistically significant difference between the two groups in the incidence of postoperative complications ( P>0.05). No recurrence was seen in both groups during postoperative follow-up. Conclusion:Da-vinci robot-assisted repair of hiatal hernia is as safe and feasible as laparoscopic procedures, with less intraoperative trauma and quicker, earlier recovery.

A preliminary experience of retroperitoneal approach by partial resection of the tenth rib for repairing Crawford type Ⅳ thoracoabdominal aortic aneurysm and complex abdominal aortic aneurysm / 中华普通外科杂志

Objective:To evaluate a surgical approach for partial resection of the tenth rib through a retroperitoneal approach for the exposure of Crawford type IV thoracoabdominal aortic aneurysm and complex abdominal aortic aneurysm from 2014 to 2019.Methods:A retrospective analysis was conducted on clinical data and follow-up results of 7 patients who underwent treatment for Crawford type IV thoracoabdominal aortic aneurysm and complex abdominal aortic aneurysm through partial resection of the tenth rib via a retroperitoneal approach.Results:One case (14.3%) had associated Marfan syndrome, and 5 cases (71.4%) underwent left renal artery reconstruction. None of the patients experienced severe complications such as cardiopulmonary complications or renal failure postoperatively, and there was no statistically significant difference in serum creatinine levels between preoperative and postoperative stages during hospitalization ( P=0.205). Follow-up examinations showed no long-term vascular stenosis. Conclusions:Partial resection of the tenth rib through a retroperitoneal approach can avoid incisions of the pleura and diaphragm. It allows for the exposure of the aorta below the diaphragm and has the ability to treat aortic diseases below the diaphragm with smaller incisions and lower complication risks.

The value of superior mesenteric artery preferential approach in the treatment of borderline resectable pancreatic head cancer / 中华普通外科杂志

Objective:To evaluate superior mesenteric artery preferential approach in the borderline resectable pancreatic head cancer.Methods:The clinical and follow-up data of 90 patients with borderline resectable pancreatic head cancer who underwent radical pancreatoduodenectomy at Beijing Chaoyang Hospital,Capital Medical University from Jan 2015 to Dec 2021 were analyzed.Results:After exploring the superior mesenteric artery in the lower colon area to confirm the vascular invasion meet the resection criteria, the blood supply is cut off first, then the tumors were resected en bloc, with the invaded vessels resected and reconstructed or replaced. All 90 patients successfully completed the operation without perioperative death. Pathology established pancreatic ductal adenocarcinoma. The 1-year, 2-year, and 3-year disease-free survival rates of patients in the arterial priority approach group were 68.2%, 60.4%, and 54.3%, while the 1-year, 2-year, and 3-year disease-free survival rates of patients by conventional approach were 58.4%, 26.4%, and 11.7% ( P=0.001). Conclusion:The superior mesenteric artery preferential approach in the inferior colon region can prolong the survival time of patients after surgery, and reduce the recurrence.

Aortic banding for refractory endoleaks after endovascular abdominal aortic aneurysm repair / 中华普通外科杂志

Objective:To summarize the safety and efficacy of aortic banding in the treatment of refractory endoleaks after endovascular abdominal aortic aneurysm repair (EVAR).Methods:The clinical and follow-up data of 10 patients with refractory endoleaks EVAR undergoing aortic banding at Peking University People's Hospital from Jun 2019 to Aprl 2022 were retrospectively analyzed.Results:The aortic banding was indicated for type Ⅰ endoleak in 6 patients, type Ⅱ endoleak in 3 patients and internal tension in 1 patient with persistent aneurysm enlargement or rupture. The surgical procedure was based on laparotomy. The proximal aortic neck was exposed and re-fixation with artificial strip to prevent bleeding. The surgical procedures was successful in all the 10 cases without residual endoleak or re-bleeding. The post-operative contrast-enhanced ultrasonography revealed neither new-onset endoleak nor occlusion of stent-grafts. Perioperative complications included one case of delayed wound healing and one case of incomplete ileus. No perioperative deaths occurred. Midterm follow-up was achieved in 10 patients with a mean follow-up time of 13 months. No recurrence of endoleak was found. One patient underwent endovascular repair for independent thoracic aortic aneurysm 6 months after surgery. There were no other aorta-related secondary surgeries or aortic-related deaths.Conclusion:Aortic banding for refractory endoleaks after EVAR is minimally invasive and reliable. It can effectively eliminate the refractory endoleaks, and reduce the risks of aortic-related secondary surgery or death.

Long-term outcome of centrally located hepatocellular carcinoma treated by radical resection combined with adjuvant radiotherapy / 中华普通外科杂志

Objective:To investigate the long-term outcome of centrally located hepatocellular carcinoma treated by radical resection and adjuvant radiotherapy(RT).Methods:A retrospective study was used to collect and analyze the clinical and pathological data of 193 patients with centrally located HCC who underwent surgery from Jun 2015 to Jun 2020. According to whether RT was used, these patients were allocated into liver resection (LR) combined RT (88 cases) and LR alone group (105 cases).Results:The 1-, 3-, and 5-year OS rates were 98%, 85%, and 74% for patients in the LR+RT group, and 79%, 66%, and 59% for patients in the LR group, respectively. The 1-, 3-, 5-year RFS rates were 76%, 55% and 44% for patients in the LR+RT group, and 51%, 40%, and 37% for patients in the LR group, respectively. OS and RFS was significantly different in LR+RT group compared with that in LR group (χ 2=5.825, P=0.016;χ 2=5.230, P=0.022, respectively). Cox analysis showed that RT was the independent prognostic factor for centrally located HCC in OS and RFS ( P=0.009, P=0.017, respectively). Subgroup analysis suggested that RT could reduce early recurrence ( HR=0.41,95% CI:0.21-0.80, P=0.002). Conclusion:Liver resection combined with adjuvant radiotherapy for centrally located HCC is safe and effective.

Comparative study of the surgical treatment for supraduodenal distal cholangiocarcinoma and Bismuth-Corlette type I hilar cholangiocarcinoma / 中华普通外科杂志

Objective:To analyze the surgical efficacy and prognosis of supraduodenal distal cholangiocarcinoma (SDC) and Bismuth-Corlette type I hilar cholangiocarcinoma (BIC), and to explore the clinical characteristics of cholangiocarcinoma at different sites.Methods:The clinical data of 33 patients with SDC and 25 patients with BIC undergoing surgical treatment at the First Affiliated Hospital of Anhui Medical University from Jan 2009 to Dec 2016 were analyzed retrospectively.Results:In the BIC group, four patients (16.0%) had combined caudate lobectomy, while in SDC group no caudate lobectomy was needed ( P=0.030). The incidence of pancreatic fistulae in SDC group and BIC group was 18.2% (6/33) and 0 (0/25), respectively ( P=0.032). The cumulative survival rates 1, 3, and 5 years after operation were 94.0%, 54.5%, and 30.3% in SDC group and 88.0%, 28.0%, and 16.0% in BIC group, respectively ( P=0.045). Univariate analysis showed that location of cholangiocarcinoma, residual status and AJCC stage were correlated with postoperative prognosis of cholangiocarcinoma patients. Multivariate analysis showed that BIC, non-R 0 resection and AJCC stage Ⅲ/Ⅳ were independent risk factors for overall survival after surgery. Conclusion:The overall survival rate of SDC patients after radical surgical resection was significantly higher than that of the BIC group.
