ABSTRACT Objective To provide insights into the potential benefits of goal-directed therapy guided by FloTrac in reducing postoperative complications and improving outcomes. Methods We performed a systematic review and meta-analysis of randomized controlled trials to evaluate goal-directed therapy guided by FloTrac in major surgery, comparing goal-directed therapy with usual care or invasive monitoring in cardiac and noncardiac surgery subgroups. The quality of the articles and evidence were evaluated with a risk of bias tool and GRADE. Results We included 29 randomized controlled trials with 3,468 patients. Goal-directed therapy significantly reduced the duration of hospital stay (mean difference -1.43 days; 95%CI 2.07 to -0.79; I2 81%), intensive care unit stay (mean difference -0.77 days; 95%CI -1.18 to -0.36; I2 93%), and mechanical ventilation (mean difference -2.48 hours, 95%CI -4.10 to -0.86, I2 63%). There was no statistically significant difference in mortality, myocardial infarction, acute kidney injury or hypotension, but goal-directed therapy significantly reduced the risk of heart failure or pulmonary edema (RR 0.46; 95%CI 0.23 - 0.92; I2 0%). Conclusion Goal-directed therapy guided by the FloTrac sensor improved clinical outcomes and shortened the length of stay in the hospital and intensive care unit in patients undergoing major surgery. Further research can validate these results using specific protocols and better understand the potential benefits of FloTrac beyond these outcomes.
RESUMO Objetivo Fornecer informações sobre os possíveis benefícios da terapia guiada por metas utilizando o sensor FloTrac na redução de complicações pós-operatórias e na melhoria dos desfechos. Métodos Realizamos uma revisão sistemática e uma metanálise de estudos controlados e randomizados para avaliar a terapia guiada por metas utilizando o sensor FloTrac em cirurgias de grande porte, comparando a terapia guiada por metas com os cuidados habituais ou o monitoramento invasivo em subgrupos de cirurgias cardíacas e não cardíacas. A qualidade dos artigos e das evidências foi avaliada com uma ferramenta de risco de viés e o GRADE. Resultados Incluímos 29 estudos controlados e randomizados com 3.468 pacientes. A terapia guiada por metas reduziu significativamente a duração da internação hospitalar (diferença média de -1,43 dia; IC95% 2,07 - -0,79; I2 81%), a internação na unidade de terapia intensiva (diferença média de -0,77 dia; IC95% -1,18 - -0,36; I2 93%) e a ventilação mecânica (diferença média de -2,48 horas, IC95% -4,10 - -0,86; I2 63%). Não houve diferença estatisticamente significativa na mortalidade, no infarto do miocárdio, na lesão renal aguda e nem na hipotensão, mas a terapia guiada por metas reduziu significativamente o risco de insuficiência cardíaca ou edema pulmonar (risco relativo de 0,46; IC95% 0,23 - 0,92; I2 0%). Conclusão A terapia guiada por metas utilizando o sensor FloTrac melhorou os desfechos clínicos e reduziu o tempo de internação no hospital e na unidade de terapia intensiva em pacientes submetidos a cirurgias de grande porte. Outras pesquisas podem validar esses resultados usando protocolos específicos e entender melhor os possíveis benefícios do FloTrac além desses desfechos.
Résumé
Abstract Autologous blood transfusion can be achieved through different techniques, including by the patient donating blood before surgery (pre-deposit), collecting blood from the patient immediately before the operation and replacing the volume with colloids or plasma expanders (acute normovolemic hemodilution) or through the salvage of lost blood, during or immediately after surgery, and its retransfusion after washing (intraoperative or postoperative recovery). We will focus on the two methods used intraoperatively that are of fundamental importance in the management and conservation of the patient's own blood.

Abstract Hemostasis plays a critical role in surgical procedures and is essential for a successful outcome. Advances in hemostatic agents offer new approaches to controlling bleeding thereby making surgeries safer. The appropriate choice of these agents is crucial. Volume replacement, another integral part of Patient Blood Management (PBM), maintains adequate tissue perfusion, preventing cellular damage. Individualization in fluid administration is vital with the choice between crystalloids and colloids depending on each case. Colloids, unlike crystalloids, increase oncotic pressure, contributing to fluid retention in the intravascular space. Understanding these aspects is essential to ensure safe and effective surgery, minimizing complications related to blood loss and maintaining the patient's hemodynamic status.

Objective@#To explore the clinical manifestations, histopathological characteristics, diagnosis, treatment, and prognosis of simultaneous unilateral primary tumors of different pathological types in the parotid gland.@*Methods@#A case of simultaneous unilateral primary parotid gland tumors, i.e., adenolymphoma and basal cell adenoma, was reviewed and analyzed in combination with the literature.@*Results@#The patient discovered a lump in the right parotid gland area one month prior to presentation, and a tumor was palpated in the shallow lobe of the right parotid gland before surgery. According to MR images, the initial diagnoses were tumors of the shallow and deep lobes of the right parotid gland. The tumors of the deep and shallow lobes were excised with part of the gland, and the facial nerves were dissected under general anesthesia. Postoperative pathology revealed an adenolymphoma in the shallow lobe of the right parotid gland and a basal cell adenoma with cystic transformation in the deep lobe. The surgical effect was good, with no complications, and there was no recurrence after 1 year of follow-up. A review of the relevant literature showed that multiple primary tumors of the parotid gland can manifest as the simultaneous presence of two or more types of tumors on both sides or on one side, and the disease is mainly treated with surgery.@*Conclusion@#Multiple unilateral primary parotid gland tumors are rare. Imaging examinations need to be combined with clinical evaluations to prevent missed diagnoses. Surgery is the first treatment option, and patients with benign tumors have a good prognosis.

Résumé
Introdução: A mamoplastia de aumento é uma dos procedimentos mais realizados em Cirurgia Plástica em todo o mundo. A mastopexia com prótese também é um procedimento amplamente realizado, reservado para outro perfil de pacientes. Muitas complicações podem ser evitadas quando se estudam os fatores de risco para desfechos desfavoráveis. Método: Trata-se de um estudo retrospectivo realizado por meio da análise de prontuários de pacientes submetidas a mamoplastia primária de aumento e mastopexia com implantes mamários no período de janeiro de 2018 a dezembro de 2020. Resultados: Das 112 pacientes submetidas a mamoplastia com implante mamário no período do estudo, 76 foram submetidas a mamoplastia de aumento primária (67,86%) e 36 pacientes a mastopexia com implante mamário (32,14%). As pacientes submetidas a mastopexia apresentaram maior média de idade em relação àquelas submetidas a mamoplastia de aumento (p<0,001) e apresentaram menores volumes de implantes mamários (p=0,002). As complicações mais comuns em ambos os grupos incluem a deiscência da ferida operatória, mais comum após mastopexia com prótese. Conclusão: A mastopexia de aumento realizada em procedimento único apresenta maior índice de complicações quando comparada à mamoplastia de aumento realizada individualmente. No entanto, o maior número de complicações precoces observadas no procedimento combinado é a soma dos dois procedimentos distintamente individuais e não um aumento exponencial.
Introduction: Breast augmentation is one of the most performed procedures in Plastic Surgery worldwide. Mastopexy with prosthesis is also a widely performed procedure reserved for other patient profiles. Many complications can be avoided when studying risk factors for unfavorable outcomes. Method: This is a retrospective study carried out through the analysis of medical records of patients who underwent primary breast augmentation and mastopexy with breast implants from January 2018 to December 2020. Results: Of the 112 patients who underwent mammoplasty with the implant during the study period, 76 patients underwent primary breast augmentation (67.86%), and 36 underwent mastopexy with breast implant (32.14%). Patients undergoing mastopexy had a higher average age compared to those undergoing breast augmentation (p<0.001) and had smaller volumes of breast implants (p=0.002). The most common complications in both groups include surgical wound dehiscence, more common after mastopexy with prosthesis. Conclusion: Breast augmentation performed as a single procedure has a higher rate of complications when compared to breast augmentation performed individually. However, the greater number of early complications observed with the combined procedure is the sum of the two distinctly individual procedures and not an exponential increase.

En Argentina existen pocas publicaciones sobre los resultados perio peratorios de este tipo de procedimiento, y menos aún sobre histerectomía mínimamente invasiva. El objetivo de este estudio fue determinar la tasa de complica ciones perioperatorias en pacientes con histerectomía total laparoscópica realizada en el Hospital Italiano de Buenos Aires, desde el 7 de enero de 2010 al 22 de diciembre de 2020. Métodos : estudio de cohorte retrospectivo donde se revisaron las historias clínicas electrónicas de pacien tes sometidas a una histerectomía laparoscópica en el período mencionado. Se evaluaron las complicaciones intraquirúrgicas y postoperatorias utilizando la clasifi cación validada de Clavien-Dindo. Resultados : Se incluyeron 1014 pacientes. La tasa de complicaciones intraquirúrgicas fue de 4.5%. Se halló una tasa de complicaciones postoperatorias de 16.6% (n=168), siendo 12.3% (n=125) Clavien-Dindo ≤ 2, y 4.2% (n=43) Clavien-Dindo ≥ 3. En el análisis multivariable que se ajustó por peso uterino >170g, edad, índice de masa corporal y más de dos cirugías abdominales pre vias, se encontró asociación entre peso uterino > 170 g y complicaciones postoperatorias, OR 1.49, IC 95% 1.04- 2.14, p = 0.03. Discusión : Al evaluar el porcentaje de complicaciones menores y mayores, nuestros números se encuentran dentro de los parámetros aceptables para realizar este tipo de cirugía, más aún, considerando que la evaluación se realizó en un ámbito educativo.
Abstract Introduction : The removal of the uterus, (hysterec tomy), is the most frequent surgery in gynecology. In Argentina there are few publications on the periopera tive results of this type of procedure, and even less on minimally invasive hysterectomy. The objective of this study was to determine the rate of perioperative compli cations in patients with total laparoscopic hysterectomy performed at Hospital Italiano de Buenos Aires, from January 7, 2010 to December 22, 2020. Methods : retrospective cohort study where electronic medical records were reviewed. Intrasurgical and postop erative complications were evaluated using the validated Clavien-Dindo's classification. Results : 1014 patients were included. The rate of intra-surgical complications was 4.5%. In respect to postoperative complications, there was found a rate of 16.6% (n=168), being 12.3% (n=125) Clavien-Dindo ≤ 2, and 4.2% (n=43) Clavien-Dindo ≥ 3. In a multivariable analysis that adjusted for uterine weight > 170g, age, body mass index, and more than two previous abdomi nal surgeries, an association was found between uterine weight >170g and postoperative complications OR 1.49, 95% CI 1.04- 2.14, p=0.03. Discussion : When evaluating the percentage of mi nor and major complications, our findings are within the acceptable parameters for performing this type of surgery, even though the evaluation was carried out in an educational setting.

ABSTRACT Objective: The optimal target for blood glucose concentration in critically ill patients is unclear. We will perform a systematic review and meta-analysis with aggregated and individual patient data from randomized controlled trials, comparing intensive glucose control with liberal glucose control in critically ill adults. Data sources: MEDLINE®, Embase, the Cochrane Central Register of Clinical Trials, and clinical trials registries (World Health Organization, clinical trials.gov). The authors of eligible trials will be invited to provide individual patient data. Published trial-level data from eligible trials that are not at high risk of bias will be included in an aggregated data meta-analysis if individual patient data are not available. Methods: Inclusion criteria: randomized controlled trials that recruited adult patients, targeting a blood glucose of ≤ 120mg/dL (≤ 6.6mmol/L) compared to a higher blood glucose concentration target using intravenous insulin in both groups. Excluded studies: those with an upper limit blood glucose target in the intervention group of > 120mg/dL (> 6.6mmol/L), or where intensive glucose control was only performed in the intraoperative period, and those where loss to follow-up exceeded 10% by hospital discharge. Primary endpoint: In-hospital mortality during index hospital admission. Secondary endpoints: mortality and survival at other timepoints, duration of invasive mechanical ventilation, vasoactive agents, and renal replacement therapy. A random effect Bayesian meta-analysis and hierarchical Bayesian models for individual patient data will be used. Discussion: This systematic review with aggregate and individual patient data will address the clinical question, 'what is the best blood glucose target for critically ill patients overall?'

Introdução: As intervenções cirúrgicas pós-bariátricas vêm se tornando cada vez mais frequentes e englobam a abdominoplastia, a cirurgia plástica interna da coxa, a braquioplastia e a mastopexia. Porém, devido ao caráter disabsortivo e restritivo do paciente bariátrico, esse estudo tem como objetivo apresentar as complicações advindas de procedimentos estéticos realizados nestes pacientes, expondo os fatores de risco mais associados às sequelas e levantando opções para um melhor desfecho. Método: Foi realizada uma revisão integrativa da literatura, de caráter qualitativo, segundo a pergunta norteadora: "Quais as principais complicações em cirurgias plásticas realizadas em pacientes bariatricados?". A busca foi realizada nas plataformas Biblioteca Virtual de Saúde (BVS) e PubMed. Os artigos incluídos no estudo foram analisados pelo método de conteúdo. Resultados: No total foram incluídos 6 artigos, nos quais observou-se que as principais complicações de cirurgias de contorno corporal, tais como a abdominoplastia e a braquioplastia, em pacientes bariatricados foram, principalmente, deiscência de feridas, seromas e hematomas, complicações, essas, relacionadas principalmente ao índice de massa corporal (IMC) do paciente, às suas comorbidades e ao tabagismo. Conclusão: Percebe-se, hoje, uma maior demanda pelas cirurgias plásticas reparadoras pósbariátrica, principalmente pela abdominoplastia. Consequentemente, houve, também, um aumento no número de complicações intraoperatórias, destacando-se o seroma e a deiscência de feridas. Para amenizá-las, a melhor solução é trabalhar no controle de fatores de risco pré-operatórios do paciente, tais como o IMC elevado e o tabagismo, além de comorbidades que levam à deficiência de cicatrização.
Introduction: Post-bariatric surgical interventions have become increasingly frequent, including abdominoplasty, inner thigh plastic surgery, brachioplasty, and mastopexy. However, due to bariatric patients' malabsorptive and restrictive nature, this study aims to present complications arising from aesthetic procedures performed on these patients, exposing the risk factors most associated with sequelae and raising options for a better outcome. Method: An integrative qualitative literature review was carried out according to the guiding question: "What are the main complications in plastic surgeries performed on bariatric patients?". The search was conducted on the Biblioteca Virtual de Saúde (BVS) and PubMed platforms. The articles included in the study were analyzed using the content method. Results: In total, 6 articles were included, in which it was observed that the main complications of body contouring surgeries, such as abdominoplasty and brachioplasty, in bariatric patients were mainly wound dehiscence, seromas and hematomas, complications, these, mainly related to the patient's body mass index (BMI), their comorbidities and smoking. Conclusion: Today, there is a greater demand for post-bariatric reconstructive plastic surgery, especially abdominoplasty. Consequently, there was also an increase in intraoperative complications, notably seroma and wound dehiscence. To alleviate them, the best solution is to work on controlling the patient's preoperative risk factors, such as high BMI and smoking, as well as comorbidities that lead to poor healing.
Résumé
Corneal melt is a sight-threatening complication of Boston type 1 keratoprosthesis (KPro). Severe corneal melt may result in hypotony, choroidal hemorrhage, and even spontaneous extrusion of the KPro, which may lead to a poor visual prognosis. Lamellar keratoplasty is one surgical option for the management of mild corneal melt, especially when a new KPro is not available. Herein, we present a new surgical technique application, intra-operative optical coherence tomography (iOCT) for the management of cornea graft melt after Boston type 1 KPro implantation. The visual acuity and the intra-ocular maintained stable at 6 months post-operatively, and the KPro remained in place without corneal melting, epithelial ingrowth, or infection. iOCT may prove to be a real-time, non-invasive, and accurate treatment for corneal lamellar dissection and suturing beneath the anterior plate of the KPro, which can effectively help the surgeon to make surgical decisions and reduce post-operative complications.

ABSTRACT Purpose: To evaluate primary intraocular lens implantation in the treatment of children's aphakia in the Brazilian public health system and compare the outcomes among different age groups. Methods: Children aged 0-12 years old with unilateral or bilateral congenital/developmental cataracts and underwent primary intraocular lens implantation were included. Results: A total of 108 eyes from 68 children were evaluated, and the children were divided into four age groups (<7 months [mo]; 7 mo-2 years old [y/o]; 2-5 y/o, and >5 y/o) were evaluated. Nineteen eyes (17.59%) presented visual axis opacification as a postoperative complication, which was more frequently observed in the <7 mo age group (37.93%). The difference was significant between the <7 mo and >5 y/o age groups (p=0.002). Visual axis opacification was divided into two categories: pupillary membrane and lens cell proliferation. Eight eyes presented pupillary membrane, whereas 14 showed lens cell proliferation. Out of eight eyes with pupillary membrane, seven occurred in the <7 mo age group. The difference between the <7 mo age group and the 2-5 y/o or >5 y/o age group was significant (p=0.01). Lens cell proliferation was more frequent in the <7 mo and 2-5 y/o age groups, but the difference was significant only between the < 7 mo age group and >5 y/o age group (p=0.040). Glaucoma and glaucoma suspect cases were not observed during the follow-up period. Conclusions: The main complication found in the study was visual axis opacification, which had a higher incidence in children operated on or before the age of 7 months.
RESUMO Objetivo: Avaliar o implante de lente intraocular primária para tratamento da afacia pediátrica no Sistema Único de Saúde (SUS) e comparar os resultados em diferentes faixas etárias. Métodos: Foram incluídas crianças com catarata congênita e do desenvolvimento unilateral ou bilateral de 0-12 anos de idade e submetidas a implante de lente intraocular primária. Resultados: Cento e oito olhos de 68 crianças divididas em quatro grupos de idade (<7m; 7m-2a; 2-5a e > 5a) foram avaliados. Dezenove olhos (17,59%) apresentaram opacificação do eixo visual como complicação pós-operatória. Essa complicação foi mais frequente na faixa etária <7 meses (37,93%). A diferença foi significativa entre os grupos de idade <7 meses e > 5 anos (p=0,002). A opacificação do eixo visual foi dividida em duas categorias: membrana pupilar e proliferação de células do cristalino. Oito olhos apresentaram membrana pupilar e 14 proliferação de células do cristalino. Dos oito olhos com membrana pupilar, sete ocorreram na faixa etária <7 meses. A diferença entre o grupo de idade <7 meses e os grupos de 2-5 anos e > 5 anos foi significativa (p=0,01). A proliferação de células do cristalino foi mais frequente nos grupos de idade <7 meses e 2-5 anos, mas significativa apenas quando comparados o grupo de idade <7 meses com o grupo> 5 anos de idade (p=0,040). Glaucoma e suspeitos de glaucoma não foram observados durante o acompanhamento. Conclusões: A principal complicação encontrada no estudo foi a opacificação do eixo visual. Sua incidência foi maior em crianças operadas antes dos 7 meses de idade.

Purpose: Barrett toric calculator (BTC) is known for its accuracy in toric IOL (tIOL) calculation over standard calculators; however, there is no study in literature to compare it with real?time intraoperative aberrometry (IA). The aim was to compare the accuracy of BTC and IA in predicting refractive outcomes in tIOL implantation. Methods: This was an institution?based prospective, observational study. Patients undergoing routine phacoemulsification with tIOL implantation were enrolled. Biometry was obtained from Lenstar?LS 900 and IOL power calculated using online BTC; however, IOL was implanted as per IA (Optiwave Refractive Analysis, ORA, Alcon) recommendation. Postoperative refractive astigmatism (RA) and spherical equivalent (SE) were recorded at one month, and respective prediction errors (PEs) were calculated using predicted refractive outcomes for both methods. The primary outcome measure was a comparison between mean PE with IA and BTC, and secondary outcome measures were uncorrected distance visual acuity (UCDVA), postoperative RA, and SE at one month. SPSS Version?21 was used; P < 0.05 considered significant. Results: Thirty eyes of 29 patients were included. Mean arithmetic and mean absolute PEs for RA were comparable between BTC (?0.70 ± 0.35D; 0.70 ± 0.34D) and IA (0.77 ± 0.32D; 0.80 ± 0.39D) (P = 0.09 and 0.09, respectively). Mean arithmetic PE for residual SE was significantly lower for BTC (?0.14 ± 0.32D) than IA (0.001 ± 0.33D) (?0.14 ± 0.32D; P = 0.002); however, there was no difference between respective mean absolute PEs (0.27 ± 0.21 D; 0.27 ± 0.18; P = 0.80). At one?month, mean UCDVA, RA, and SE were 0.09 ± 0.10D, ?0.57 ± 0.26D, and ?0.18 ± 0.27D, respectively. Conclusion: Both IA and BTC give reliable and comparable refractive results for tIOL implantation.

Abstract Objectives: The aim of this study was to assess the relationship between the stimulation amplitude and the distance to the facial nerve. Methods: This study was designed as a prospective clinical study. A total of 20 patients (12 males, 8 females) were included. Partial superficial parotidectomy was performed in all patients with intraoperative facial monitoring. Measurements were made on the main trunk and major branches. Stimulation was started at 1 mA and incrementally increased to 2 and 3mA's. The shortest distance creating a robust response (>100mV) was recorded. Results: At 1 mA, 2 mA and 3 mA stimulation intensity, the average distance between the tip of the stimulation probe and the main trunk was 2.20±0.76 mm (range 1-3 mm), 3.80±0.95 mm (range 2-5 mm), 4.80±1.05 mm (range 3-7 mm) respectively. The stimulus intensity was inversely proportional in respect to the distance between the nerve and the tip of the stimulus probe (P < .00). The same relation was present in the facial nerve major branch measurements (P < .00). Conclusion: The proportional stimulation amplitude and distance to the facial nerve is thought to be a reliable auxillary method to assist the surgeon by facilitating the estimation of the distance to the facial nerve during extracapsular dissection and minimally invasive cases where the facial nerve isn't routinely dissected. Level of evidence: Level 3.
Résumé
El bad split es un término clínico que refiere a una fractura no planificada que ocurre al momento de realizar una osteotomía sagital de rama mandibular (OSRM). Afecta aproximadamente al 2,3% de los pacientes y se han descrito factores de riesgo tales como la presencia de terceros molares mandibulares, edad avanzada al momento de la cirugía, técnica de osteotomía inadecuada, entre otros. Se recomienda efectuar manio-bras preventivas para evitar la aparición de patrones de fractura no deseados al realizar la OSRM. Sin embargo, al momento de pesquisar un bad split, éste debe ser tratado por un equipo capacitado y de manera oportuna para evitar retardo en la consolidación, infecciones y secuestros óseos que puedan comprometer los resultados de la cirugía. En este artículo se presenta el manejo de un caso clínico de bad split bilateral intraoperatorio por el Servicio de Cirugía Maxilofacial del Hospital San José, enfatizando su tratamiento quirúrgico.
Bad Split is a clinical term referring to an unplanned fracture that occurs during the bilateral sagittal split osteotomy (BSSO). It affects approximately 2,3% of the patients undergoing orthognathic surgery and several risk factors have been described such as the presence of mandibular third molars, advanced age at the moment of orthognathic surgery, inadequate osteotomy technique, etc. Preventive maneuvers are recommended in order to avoid the appearance of undesired fracture patterns during BSSO. However, if a bad split is detected it must be managed and treated by a qualified team to avoid further complications such as delayed bone consolidation, bone infection and necrosis. In this article we present the management of a case of bilateral bad split by the Maxillofacial Surgery Service of Hospital San José, emphasizing on its surgical treatment.

Introducción: La calcificación del catéter doble J puede encontrarse en el 13 % de los colocados y aumenta proporcionalmente al tiempo que permanezca en contacto con la orina. Los investigadores coinciden en que el catéter doble J calcificado es una complicación compleja de resolver. Se realizó una revisión bibliográfica, de 2011 a 2021. Se utilizaron las bases de datos SciELO, EBSCO, Elsevier y PubMed, con los descriptores: litiasis, catéteres, procedimientos quirúrgicos mínimamente invasivos y complicaciones intraoperatorias y posoperatorias. Objetivo: Describir el papel de la cirugía mínimamente invasiva para el tratamiento del catéter doble J calcificado. Desarrollo: Los factores de riesgo relacionados a catéter doble J calcificados son clínico-terapéuticos y sociodemográficos, como la infección urinaria, antecedentes de litiasis, embarazo, enfermedad renal crónica, anomalías metabólicas o congénitas. Los de poliuretano presentan mayores tasas de calcificación. La litotricia extracorpórea por ondas de choque puede emplearse hasta en 70,7 % de los pacientes. Métodos multimodales como ureteroscopía, previa cistolitotricia transuretral, se han aplicado entre 6 % y 17,9 %, la nefrolitotomía percutánea y ureteroscopía, previa cistolitotricia o no, en el 7,7 % al 20 %. Las complicaciones más frecuentes se informan durante el posoperatorio (20 %): fiebre, dolor, vómitos, hematuria, pielonefritis, sepsis, urinoma, migración espontánea del nuevo catéter colocado y daño renal agudo, entre otras. Conclusiones: La cirugía mínimamente invasiva en la actualidad es el pilar fundamental, del tratamiento de los pacientes con catéter doble J calcificado.
Introduction: The calcification of the double J catheter can be found in 13% of those placed and increases proportionally to the time it remains in contact with urine. The researchers agree that the calcified double J catheter is a complex complication to resolve. A bibliographic review was carried out, from 2011 to 2021. The resources of the SciELO, EBSCO, Elsevier and PubMed databases were used in relation to the descriptors lithiasis, catheters, minimally invasive surgical procedures and intraoperative and postoperative complications. Objective: To describe the role of minimally invasive surgery for the treatment of calcified double J catheter. Development: The risk factors related to calcified double J are clinical-therapeutic and sociodemographic, such as urinary tract infection, history of lithiasis, pregnancy, chronic kidney disease, metabolic or congenital anomalies. Those made of polyurethane have higher rates of calcification. Extracorporeal shock wave lithotripsy can be used in up to 70.7% of patients. Multimodal methods such as ureteroscopy prior to transurethral cystolithotripsy have been applied between 6-17.9%, percutaneous nephrolithotomy and ureteroscopy prior cystolithotripsy or not in 7.7%-20%. The most frequent complications are reported during the postoperative period (20%): fever, pain, vomiting, hematuria, pyelonephritis, sepsis, urinoma, spontaneous migration of the newly placed catheter, and acute kidney injury, among others. Conclusions: Minimally invasive surgery is currently the cornerstone of treatment for patients with calcified double-J catheters.
Résumé
Introducción: La cirugía endoscópica nasosinusal ha evolucionado de forma importante desde su creación. La posición anatómica que ocupan las cavidades nasosinusales con importantes estructuras adyacentes hacen que sus complicaciones, aunque raras, traigan secuelas irreversibles e incluso la muerte del paciente. Objetivo: Realizar una revisión sobre los tipos de complicaciones, frecuencia y su manejo durante la cirugía endoscópica nasosinusal. Métodos: Revisión documental en bases de datos bibliográficos sobre el tema durante el período de diciembre 2021 a enero 2022. Se seleccionaron 27 artículos relacionados con el objetivo propuesto y se desarrolló un documento resumen con la información recolectada. Desarrollo: La clasificación más utilizada separa las complicaciones en tres grados de severidad y las tasas de complicaciones mayores están por debajo del 1 por ciento en manos de cirujanos experimentados. Reconocer los sitios de mayor riesgo y los síntomas que puedan aparecer en el paciente son fundamentales para el rápido manejo de la complicación. Conclusiones: La cirugía endoscópica nasosinusal ha demostrado ser una excelente herramienta para el tratamiento quirúrgico de las enfermedades de estas cavidades en manos experimentadas. Aunque las tasas de complicaciones son ínfimas, saber reconocerlas y tratarlas a tiempo resulta fundamental(AU)
Introduction: Endoscopic nasosinusal surgery has evolved significantly since its inception. The anatomical position of the nasosinusal cavities, with important adjacent structures, means that its complications, although rare, bring about irreversible sequelae, and even death, for the patient. Objective: To review the types and frequency of complications, as well as their management, during endoscopic nasosinusal surgery. Methods: A documentary review on the subject was conducted in bibliographic databases during the period from December 2021 to January 2022. Twenty-seven articles related to the proposed objective were selected, while a summary document was developed with the collected information. Development: The most commonly used classification separates complications into three degrees of severity and includes major complication rates below 1 percent in the hands of experienced surgeons. Recognizing the sites of greatest risk and the symptoms that may appear in the patient are fundamental for the rapid management of the complication. Conclusions: Endoscopic nasosinusal surgery has proven to be an excellent tool for the surgical treatment of the diseases of these cavities in experienced hands. Although complication rates are minimal, it is essential to know how to identify and treat them(AU)
