Long-term functional outcomes and surgical retreatment after thulium laser enucleation of the prostate: A 10-year follow-up study

ABSTRACT Background: To evaluate the 10-year functional outcomes (primary) and frequency and predictors of BPH surgical retreatment (secondary) after ThuLEP. Materials and Methods: A single-center retrospective analysis of consecutive patients undergoing ThuLEP between 2010 and 2013 was performed. Inclusion criteria were: age ≥ 40 years, prostate volume (PV) ≥ 80 mL, International Prostate Symptom Score (IPSS)-Total score ≥ 8 points. IPSS-Total score was the primary outcome, and BPH surgical retreatment rate was the secondary outcome. Paired t-test, McNemar test, and Wilcoxon signed-rank test were used to compare variables. Logistic regression analysis was performed to evaluate predictors of surgical retreatment. Results: A total of 410 patients with a mean ±SD age of 63.9 ± 9.7 years and a PV of 115.6 ± 28.6 mL were included. Mean ±SD follow-up was 108.2 ± 29.6 months. IPSS-Total score was significantly improved at 1 year compared to baseline (23.3 ± 4.7 vs. 10.3 ± 3.8; p<0.001). It was similar after 5 years (10.5 ± 3.6 vs. 10.7 ± 5.0; p=0.161), with a significant worsening at 10 years (10.3 ±4.8 vs. 13.8 ±4.5; p=0.042) but remaining statistically and clinically better than baseline (13.8 ±4.5 vs. 22.1 ±4.3; p<0.001). After 10 years, 21 (5.9%) patients had undergone BPH reoperation. Baseline PV (adjusted OR 1.27, 95% CI 1.09-1.41; p<0.001) and time from BPH surgery (adjusted OR 1.32, 95% CI 1.15-1.43; p<0.001) were predictors of BPH surgical retreatment. Conclusions: ThuLEP is associated with optimal functional outcomes and a low frequency of BPH surgical retreatment in the long-term. Baseline PV and time from surgery were predictors of BPH reoperation.

Sutura em Polia Retificada para síntese de feridas de pele tensionadas / Rectified Pulley Suture for the synthesis of tensioned skin wounds

Introdução: A síntese de feridas de pele tensionadas é uma área que tem sido alvo de estudos para o desenvolvimento de técnicas de sutura que sejam capazes de realizar o fechamento primário dessas feridas com alívio de tensão, garantindo uma cicatrização adequada e evitando complicações como deiscência, edema, sangramento e infecção. Método: Esta pesquisa tratou-se de um estudo piloto, sendo a primeira apresentação da técnica de Sutura em Polia Retificada para síntese de feridas de pele tensionadas através do acompanhamento prospectivo, duplo-cego, de uma série de casos de 8 pacientes randomicamente admitidos no centro cirúrgico de um hospital de alta complexidade de uma cidade de médio porte. Resultados: A Sutura em Polia Retificada é uma técnica versátil e apta para lidar com feridas de pele tensionadas, uma vez que no intraoperatório conseguiu fechar por primeira intenção lesões de até 6,5 centímetros e de diferentes regiões tensionadas sem necessidade do uso de técnicas mais complexas, como retalhos, enxertos, zetaplastia e fechamento por segunda intenção. Além disso, no pós-operatório, houve redução dos escores da POSAS, indicando um processo de cicatrização satisfatório tanto para os observadores quanto para o paciente. É imprescindível mencionar, também, que o desfecho mais temido no seguimento dos pacientes com feridas tensionadas submetidos a fechamento primário - a deiscência - foi completamente evitado. Conclusão: A técnica é simples, confiável, segura e reprodutível, com curta curva de aprendizagem, de forma que a Sutura em Polia Retificada pode ser considerada como uma nova ferramenta a ser integrada ao arsenal cirúrgico.

Introduction: The synthesis of tensioned skin wounds is an area that has been the subject of studies for the development of suturing techniques that are capable of performing the primary closure of these wounds with tension relief, ensuring adequate healing, and avoiding complications such as dehiscence, edema, bleeding, and infection. Method: This research was a pilot study, being the first presentation of the Rectified Pulley Suture technique for the synthesis of tensioned skin wounds through prospective, double-blind monitoring of a series of cases of 8 patients randomly admitted to the surgical center of a high-complexity hospital in a mediumsized city. Results: Rectified Pulley Suture is a versatile technique suitable for dealing with tensioned skin wounds, since intraoperatively it was able to close, by first intention, lesions measuring up to 6.5 centimeters and in different tensioned regions without the need for the use of more extensive techniques. complex, such as flaps, grafts, Z-plasty, and secondary intention closure. Furthermore, post-operatively, there was a reduction in POSAS scores, indicating a satisfactory healing process for both observers and the patient. It is also essential to mention that the most feared outcome in the follow-up of patients with tension wounds undergoing primary closure - dehiscence - was completely avoided. Conclusion: The technique is simple, reliable, safe, and reproducible, with a short learning curve, so the Rectified Pulley Suture can be considered a new tool to be integrated into the surgical arsenal.

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.

Trauma in the vertebral spine: determining factors in the time for the surgery / Traumatismo na coluna vertebral: fatores determinantes no tempo para realização da cirurgia / Lesiones en la columna vertebral: factores determinantes en el tiempo para la cirugía

ABSTRACT Objective: Quantify the time elapsed between the arrival of the patient with surgical trauma in the spine at the emergency room and the completion of the surgical procedure, analyzing the factors that may have influenced this process. Methods: Retrospective study that included individuals of both sexes aged between 18 and 100 years who arrived at a tertiary trauma center with surgical fractures in the spine. Patients treated between March 2018 and March 2022 were included in the sample. All data to compose the study sample were collected from secondary data sources (medical records). Results: Medical records of 259 patients with spinal injuries were evaluated. Approximately one-third of the patients were operated on between 13h and 24h, and the other third over 72h. Only 6.6% were operated within 12 hours. The mean time to perform the surgical process was 84.3 ± 144.6 hours. Surgical intervention for most patients (59.1%) occurred within the first 48 hours. Patients with systemic arterial hypertension and patients with at least one comorbidity had a statistically longer mean waiting time for the surgical procedure than patients who did not have these characteristics. Conclusion: Most surgical interventions occurred in the first 48 hours, which is considered early. In addition, some factors, such as the existence of comorbidities, are directly associated with the time it takes to perform the surgical procedure. Level of Evidence II; Retrospective Prognostic.

Minimally Invasive Tibiotalocalcaneal Arthrodesis with Blocked Retrograde Intramedullary Nail - Report of Three Cases / Artrodese tibiotalocalcaneana minimamente invasiva com haste intramedular retrógrada bloqueada - Relato de três casos

Abstract Ankle osteoarthritis (AOA) is associated with pain and variable functional limitation, demanding clinical treatment and possible surgical indication when conservative measures are ineffective - arthrodesis has been the procedure of choice, because it reduces pain, restores joint alignment and makes the segment stable, preserving gait. The present study reports 3 cases (3 ankles) of male patients between 49 and 63 years old, with secondary AOA, preoperative American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS AHS) of 27 to 39 points, treated by minimally invasive tibiotalocalcaneal arthrodesis using blocked retrograde intramedullary nail. Hospital stay was of 1 day, and the patients were authorized for immediate loading with removable ambulation orthotics, as tolerated. The physical therapy treatment, introduced since hospitalization, was maintained, prioritizing gait training, strength gain, and proprioception. Clinical and radiographic follow-up was performed at weeks 1, 2, 6, 12 and 24. After evidence of consolidation (between the 6th and 10th weeks), the orthotics were removed. One patient complained of pain in the immediate postoperative period and, at the end of the 1st year, only one patient presented pain during rehabilitation, which was completely resolved with analgesics. Currently, the patients do not present complaints, returning to activities without restrictions - one of them, to the practice of soccer and rappelling. The postoperative AOFAS AHS was from 68 to 86 points.

Resumo A osteoartrite do tornozelo (OAT) está associada a quadro álgico e limitação funcional variável, demandando tratamento clínico e eventual indicação cirúrgica quando as medidas conservadoras são inefetivas - a artrodese tem sido o procedimento de escolha, por reduzir a dor, restaurar o alinhamento articular e tornar o segmento estável, preservando a marcha. O presente estudo relata 3 casos (3 tornozelos) de pacientes do sexo masculino, com entre 49 e 63 anos de idade, portadores de OAT secundária, American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS AHS, na sigla em inglês) pré-operatória de 27 a 39 pontos, tratados mediante artrodese tibiotalocalcaneana minimamente invasiva utilizando haste intramedular retrógrada bloqueada. A permanência hospitalar foi de 1 dia, e os pacientes foram autorizados para carga imediata com órteses removíveis para deambulação, conforme tolerado. O tratamento fisioterápico, introduzido desde o internamento, foi mantido, priorizando-se treino de marcha, ganho de força e propriocepção. Foi realizado acompanhamento clínico e radiográfico nas semanas 1, 2, 6, 12 e 24. Após evidências de consolidação (entre a 6ª e a 10ª semanas), as órteses foram retiradas. Um paciente queixou-se de dor no pós-operatório imediato e, ao final do 1° ano, apenas 1 paciente apresentou dor durante a reabilitação, resolvida completamente com analgésicos. Atualmente, os pacientes não apresentam queixas, retornando às atividades sem restrições - um deles, à prática de futebol e rapel. A AOFAS AHS pós-operatória foi de 68 a 86 pontos.

Comminution of the medial wall, how to identify this situation and its behavior are mentioned. In relation to associated injuries, it is recommended to first stabilize the forearm and then the supracondylar fracture. For unstable fractures in flexion, the technique to be used is recommended. For its part, the conversion from closed to open reduction is justified in certain circumstances that are described in the article. Conclusions: Supracondylar fractures of the humerus in children are mostly treated by surgical treatment. During the trans-operative period situations may arise for which the treating physician must be prepared.

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.

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.

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.

Clinical analysis of 12 cases of primary urethral carcinoma / 中华老年医学杂志

Objective:To investigate the clinical features, diagnosis, treatment and prognosis of primary urethral carcinoma.Methods:The clinical and follow-up data of 12 patients with primary urethral carcinoma admitted to Beijing Hospital from July 2016 to December 2020 were retrospectively analyzed.Results:There were four males and eight females, with an average age of 66.3(53~75)years.Nine patients underwent magnetic resonance examination before operation, and eight patients presented with abnormal urethral signals.The clinical stage of female patients was generally later than those of male patients, and all patients received surgical treatment.Four male patients did not receive post-operative adjuvant treatment, and all of them attained disease-free survival.Among the eight female patients, four patients received postoperative adjuvant radiotherapy or chemotherapy, five patients had recurrence or metastasis during follow-up, and two patients died.Conclusions:The clinical stage of female urethral cancer is later than that of male.MRI examination is beneficial to the determination of local invasion of urethral cancer.For female proximal urethral cancer and male posterior urethral cancer, radical resection has a good therapeutic effect.

Effect of modified blood management strategies on blood loss and transfusion rate during outpatient total hip arthroplasty / 中华骨科杂志

Objective:To explore the impact of a modified blood management strategy on blood loss and transfusion rates during outpatient total hip arthroplasty(THA).Methods:The retrospective research was performed in a total of 125 patients (125 hips) who underwent outpatient primary THA from January 2019 to December 2021 at a medical center. According to whether a modified blood management protocol was used or not, all patients were divided into two groups. Group A was used the original perioperative blood management strategies (1 g tranexamic acid, intravenously, 10 minutes before skin incision), and group B was used the modified perioperative blood management strategy (on the basis of the original protocol, 2 g tranexamic acid was sprayed locally in the joint cavity before the incision was closed, 1 g tranexamic acid was injected intravenously 3 hours after surgery, and 1 g tranexamic acid was injected intravenously again on the first day after surgery). There were 52 cases in group A, including 32 males and 20 females, aged 58.5±9.8 years (range, 39-69 years), 13 cases were developmental hip dysplasia (Crowe I°-II°), 24 cases were avascular necrosis of the femoral head, 10 cases were hip osteoarthritis, 3 cases were ankylosing spondylitis involving hip joint, and 2 cases were femoral neck fracture. Among the 73 patients in group B, there were 43 males and 30 females, aged 55.8±10.4 years (range, 42-67 years), including 17 cases of developmental hip dysplasia (Crowe I°-II°), 32 cases of avascular necrosis of the femoral head, 16 cases of hip osteoarthritis, 7 cases of ankylosing spondylitis involving hip joint, and 1 case of femoral neck fracture. Intraoperative blood loss, transfusion, deep vein thrombosis (DVT) events (vascular ultrasound, 2w Postop.), the hemoglobin (Hb) drop, the hematocrit (Hct) drop and other complications were recorded.Results:After using the modified strategy, the intraoperative blood loss was significantly reduced (305.6±38.6 ml vs. 416.2±88.3 ml, t=9.51, P<0.001), and the drop of hemoglobin was significantly decreased (18.1±4.0 g/L vs. 22.3±5.8 g/L, t=4.97, P<0.001). The drop of Hct also decreased significantly (7.3%±0.7% vs. 9.6%±1.3%, t=10.21, P<0.001), and total blood loss decreased significantly (720.6±57.4 ml vs. 919.6±86.3 ml, t=15.49, P<0.001). The hidden blood loss was also significantly lower than that in group A (414.9±71.1 ml vs. 503.5±96.4 ml, t=5.91, P<0.001). One patient (in group A) developed intra-articular hemorrhage 2 h after surgery and was transferred back to the inpatient ward for treatment after transfusion. Three patients (2.4%, 1 in group A and 2 in group B) developed symptomatic anemia and were discharged successfully after conservative treatment. Calf muscular venous thrombosis occurred in 3 patients (2.4%), but no symptomatic deep vein thrombosis occurred in all patients. Conclusion:According to this retrospective research, the use of modified blood management strategy during outpatient THA can further reduce intraoperative blood loss, hidden blood loss and postoperative hematocrit drop, and does not increase the occurrence of perioperative thrombosis-related complications.

Progress in open surgical treatment of thoracolumbar kyphosis secondary to old osteoporotic vertebral compression fractures / 中华骨科杂志

Osteoporotic vertebral compression fracture (OVCF) is the most common complication of spinal osteoporosis, mostly occurring in thoracolumbar segment, which can cause acute and chronic pain at the fracture site and loss of vertebral height, and can lead to progressive kyphosis. For kyphosis caused by old OVCF, open surgery such as anterior or posterior decompression and fusion, internal fixation and osteotomy can improve local sequence and achieve satisfactory kyphotic correction which is difficult to complete in percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP), and reconstruct the sagittal balance. Due to the older age of OVCF patients, some of them have poor general conditions. In addition, osteoporosis leads to increased vertebral fragility, which increases the risk of surgery and postoperative internal fixation failure. The anterior approach presents some problems including a complex approach and poor mechanical stability. At present, most studies focus on posterior surgery. Due to the limitation of kyphosis correction by decompression and fixation alone, osteotomy is often required to correct kyphosis. In cases of old OVCF with kyphosis, the screw holding capability decreases due to the decrease of bone mineral density. Additionally, once the screw loosens, the orthopedic effect is inevitably affected. To enhance pedicle screws, most studies have utilized bone cement to increase the axial pullout force of the vertebral body and improve screw stability. The selection from different osteotomy methods is a critical determinant in achieving favorable surgical outcomes for patients.

Treatment of patients with sentinel bleeding after hepatobiliary and pancreatic surgery / 中华肝胆外科杂志

Objective:To compare the results of operative versus interventional treatments in patients presenting with sentinel hemorrhage after hepatobiliary and pancreatic surgery.Methods:The clinical data of patients presenting with sentinel hemorrhage after hepatobiliary and pancreatic surgery at the Department of Hepatobiliary Surgery, the Second Affiliated Hospital of Guangzhou Medical University from August 2017 to July 2022 were retrospectively analyzed. Of 82 patients who were enrolled in this study, there were 50 males and 32 females, aged (59.0±7.7) years. The patients were divided into the interventional group ( n=42) and the surgical group ( n=40) based on the treatment they received for sentinel hemorrhage. The vascular injury rate, the first operation time for sentinel bleeding, the rate of successful hemostasis in a single operation, the number of deaths and other indicators were compared between groups. Results:In both the two groups of patients who underwent percutaneous transhepatic cholangial drainage, hepatectomy, endoscopic retrograde cholangiopancreatography, hilar cholangiocarcinoma resection and cholecystectomy were mainly performed hepatic artery injury, pancreaticoduodenectomy with gastroduodenal artery injury, and splenectomy with splenic artery injury. In the intervention group, 36 patients (85.7%) were successfully hemostasis after single treatment, and 32 patients (80.0%) in the operation group, and there was no significant difference between the two groups (χ 2=0.47, P=0.492). The first operation time for the intervention group was (40.5±8.5) min and the mortality rate was 2.4% (1/42), which were significantly better than that of the operation group (90.6±20.8) min and 15.0% (6/40) (all P<0.05). Conclusion:Interventional therapy can be used as the first-line diagnosis and treatment for sentinel bleeding after hepatobiliary and pancreatic surgery. It has the advantages of a lower mortality rate in treating these patients.

Clinical effectiveness of endoscopic versus surgical treatment of chronic pancreatitis: a meta-analysis / 中华肝胆外科杂志

Objective:To compare the efficacy of endoscopy and surgery in chronic pancreatitis.Methods:CNKI, CBM, Wanfang, PubMed, Cochrane Library, Embase and Web of Science were searched to compared endoscopy and surgery for the clinical efficacy of chronic pancreatitis. Literatures were searched from the establishment of the database to August 14, 2022. Compared pain relief, clinical response to initial treatment, complications, endocrine/exocrine insufficiency, length of hospital stay and mean number of procedures between the two groups. Manager 5.4.1 software was used for data analysis. Odds ratio ( OR) or weighted mean difference ( WMD) was calculated with 95% confidence interval (95% CI). Results:A total of seven studies were included, including three randomized controlled trials and four retrospective studies with 708 patients. There were 513 males and 195 females. Endoscopic interventions were performed in 364 patients and 344 patients underwent surgery. The results of meta-analysis showed that the total pain relief rate ( OR=0.38, 95% CI: 0.24-0.59) and the complete pain relief rate ( OR=0.47, 95% CI: 0.29-0.77), short-term (1-1.5 years) pain relief rate ( OR=0.42, 95% CI: 0.24-0.74), clinical relief rate ( OR=0.23, 95% CI: 0.10-0.55) were better than the endoscopic group, and could significantly reduce the number of reoperation ( WMD=1.64, 95% CI: 0.89-2.40), and the difference was statistically significant (all P<0.05). There were no significant differences in complications, new-onset endocrine insufficiency, new-onset exocrine insufficiency and length of hospital stay between the endoscopy group and the surgical group (all P>0.05). Conclusion:Surgical intervention is superior to endoscopic treatment in controlling pain associated with chronic pancreatitis and in clinical relief after the first treatment, and can effectively reduce the number of reoperations.
