ABSTRACT

ABSTRACT Objective: To evaluate the efficacy of low-cost nucleus fragmenting forceps designed to reduce the use of ultrasound during phacoemulsification. Methods: A total of 60 pig eyes enucleated 10 hours before were placed in the microwave oven, at maximum power for 10 seconds, to form cataracts with hardness comparable to a grade IV nucleus in the Lens Opacities Classification System III. Cataract extraction was performed using the Centurion® phacoemulsifier (Alcon Laboratories, Geneve, Switzerland) and Leica M620 microscope. All eyes were submitted to the pre-chop technique dividing the nucleus into four parts. After the pre-chop, the quadrants in 30 eyes were phacoemulsified with the torsional mode and were fragmented in the remaining 30 eyes after the pre-chop was with the fragmentation forceps before torsional mode phacoemulsification. The device was calibrated for all eyes by applying the following parameters: 40% linear torsional phacoemulsification; intraocular pressure of 65 mmHg; the linear vacuum of 600 mmHg; aspiration flow of 40 ccs/minute. After each procedure, the following was recorded: cumulative dissipated energy; equivalent average torsional amplitude; equivalent average ultrasonic power; estimated aspirated fluid; ultrasound total time; and total aspiration time. Statistical analysis was performed using the Kruskal-Wallis test and the IBM Statistical Package for Social Sciences. The p-value <0.05 was considered statistically significant. Results: There was a statistically significant reduction favoring the use of the nucleus fragmenting forceps in all parameters, except for the average torsional amplitude. Conclusion: The use of the nucleus fragmenting forceps contributed to improving the efficacy of torsional phacoemulsification in enucleated pig eyes.


RESUMO Objetivo: Avaliar a eficácia de uma pinça fragmentadora de núcleo, de baixo custo, desenvolvida para reduzir o uso de ultrassom durante a emulsificação do núcleo. Métodos: Sessenta olhos de porco com 10 horas de enucleação foram colocados no forno de microondas, em potência máxima por 10 segundos, para a formação de catarata com dureza comparável à de um núcleo grau IV na Lens Opacities Classification System III. A extração da catarata foi realizada com o facoemulsificador Centurion® (Alcon Laboratories, Genebra, Suíça) e microscópio Leica M620. Todos os olhos foram submetidos a técnica de pre-chop, dividindo o núcleo em quatro partes. Em 30 olhos, após o pre-chop, foi feita a facoemulsificação dos quadrantes com o modo torsional e, nos outros 30 olhos, após o pre-chop, cada quadrante foi fragmentado com a pinça antes da facoemulsificação com o modo torsional. O aparelho foi calibrado para todos os olhos com os seguintes parâmetros: faco torsional linear 40%; pressão intraocular 65 mmHg; vácuo linear 600mmHg e fluxo de aspiração 40cc/minuto. Após cada procedimento, verificaram-se energia dissipada acumulada; média da amplitude do faco torsional; média equivalente do poder ultrassônico; líquido aspirado estimado; tempo total de ultrassom e tempo total de aspiração. A análise estatística foi realizada utilizando o teste de Kruskal-Wallis com o IBM Statistical Package for Social Sciences. Valor de p<0,05 foi considerado estatisticamente significante. Resultados: Houve redução estatisticamente significante em favor do uso da pinça fragmentadora de núcleo em todos os parâmetros, menos na média de amplitude do faco torsional. Conclusão: O uso da pinça fragmentadora de núcleo contribuiu para melhorar a eficácia do faco torsional em olhos de porco enucleados.

ABSTRACT

The glasses-free three dimensional(3D) endoscopic display system provides the surgeon with the depth information of the minimally invasive surgery scene obtained from the binocular perspective, which can effectively relieve the surgeon's posture fatigue and visual fatigue during the long-term surgery, and assist in the operation of surgical instruments more accurately to reduce the damage to the surrounding tissues of the operation area. However, the glasses-free 3D display device currently has the problem of a narrow optimal viewing zone and easy crosstalk, especially in the surgical teaching application scenario, which performs poorly. In order to overcome the limitation of the narrower field of view, we introduce deep learning algorithms to detect and locate multiple faces, fine-tune the 3D display grating of the endoscope, rearrange pixels, and change the best view area, so that more people can get the best view. The experimental results show that the face detection accuracy of the method is 97.88%, and the detection time is 135 frames/ms, which achieves high accuracy while maintaining real-time performance.

ABSTRACT

RESUMEN La resección gástrica atípica ha demostrado ser beneficiosa para tumores submucosos. La técnica pre senta mayor riesgo cuando estos se desarrollan próximos a la unión esófago-gástrica (UEG). Para esta limitación se propuso la resección intragástrica mediante una técnica mixta combinando laparoscopia y endoscopia. En nuestro medio no existen publicaciones al respecto. Se trata de una mujer de 42 años, con lesión subepitelial-subcardial de 2 cm, evaluada mediante videoendoscopia alta (VEDA), compa tible con tumor del estroma gastrointestinal (GIST) evaluado mediante ecoendoscopia. La lesión fue resecada mediante abordaje combinado laparoendoscópico. Bajo visión laparoscópica se introdujeron en cavidad abdominal trocares con balón, y bajo visión endoscópica intragástrica se introdujeron estos en el estómago y se fijó la pared gástrica a la pared abdominal insuflando dichos balones. Posterior mente se realizó la resección de la lesión con sutura mecánica. El abordaje combinado es seguro y eficaz, simple en manos entrenadas, pero constituye una opción reproducible en casos seleccionados.


ABSTRACT Atypical gastric resection has proved to be beneficial to treat submucosal tumors. The technique is more difficult when these tumors develop next to the gastroesophageal junction (GEJ). Intragastric resection combining endoscopic and laparoscopic approach was proposed to solve this limitation. There are no publications about this technique in our environment. A 42-year-old female patients with a 2-mm subepithelial tumor below the cardia evaluated by upper gastrointestinal (UGI) videoendoscopy and endoscopic ultrasound suggestive of a gastrointestinal stroma tumor (GIST) underwent resection using the combined laparo-endoscopic approach. Under laparoscopic guidance, balloon-tipped trocars were introduced in the abdominal cavity and then into the stomach using endoscopic view. The balloons were inflated to fix the gastirc wall to the abdominal wall. The lesion was resected using mechanical stapler. The combined approach is safe and efficient, and simple to perform for trained professionals, constituting a reproducible option in selected cases.

ABSTRACT

Objective: To investigate the feasibility, efficacy and safety of transbrachial access for interventional therapy on prosthetic paravalvular leak (PVL) post surgical valve replacement. Methods: This is a retrospective study. Patients with PVL after surgical valve replacement who underwent interventional therapy via the brachial artery approach in Structural heart disease center of Fuwai hospital between August 2017 and October 2019, were included. All patients underwent puncture of the brachial artery under local anesthesia, angiography and transcatheter closure procedure were performed. The procedure was performed under transthoracic echocardiography (TTE) guidance. Baseline data, operation data and pre-and post-operative TTE examination results were collected and analyzed. Postoperative complications were recorded and operational adverse events were obtained during follow up in the outpatient department after discharge. The operation success rate was calculated, which was defined as the degree of perivalvular regurgitation decrease by 1 grade and above according to TTE without interfering the valve movement and coronary artery blood flow within 30 days after occluder placement. Results: A total of 10 patients were enrolled in this study, the mean age was (57.5±14.6) years, and 6 patients were males. There were 7 cases with aortic PVL, and 3 cases with mitral PVL. Except for one patient who was converted to the femoral vein-transseptal approach, the other 9 patients were successfully implanted with the devices via the brachial artery approach. The operation time was (103.3±34.0) minutes, and there was no need for rigorous bed rest after the operation. The median hospital stay was 7.5 (3.0, 9.8) days. The operation success rate was 9/10 via the brachial artery approach. The differences in the degree of perivalvular regurgitation, New York Heart Association (NYHA) classification, left ventricular end diastolic diameter and left atrial diameter before and after operation were statistically significant (all P<0.05). One case developed new hemolysis with renal insufficiency on the second day after procedure and discharged after successful dialysis. Another case experienced complication of brachial artery pseudoaneurysm after procedure and discharged after successful treatment with thrombin injection. The mean follow-up time was (14.3±7.9) months. During the follow-up, NYHA classification remained as Ⅰ/Ⅱ in 9 patients, no operational adverse events were observed. Conclusions: Transbrachial access for interventional therapy on PVL post surgical valve replacement is a feasible, effective, and safe procedure. It has the advantages of simplifying the operation process and reducing postoperative bed rest time.

ABSTRACT

ABSTRACT Purpose To investigate the applicability of piezosurgery for cervical ventral slot (CVS), comparing it with the conventional technique of using high-speed burs for bone wear. Methods Thirty rabbits (Oryctolagus cuniculus) were divided into two treatment groups (T1 and T2) corresponding to CVS between C3-C4. In T1, the surgery was performed with piezoelectric apparatus, and in T2 with high-speed burs. The evaluated parameters were: duration of each stage of surgery, temperature variations during CVS, visibility of the surgical field, intra and postoperative complications, and anesthetic monitoring. At 14, 28, and 56 postoperative days, five animals from each treatment group were submitted for histopathological study of the surgical site. Results Compared with T2, T1 had more precise bone cut, and better visibility of the operative field, although it required longer total surgical time (p = 0.02) and triggered a greater number of intraoperative complications (p < 0.01), microscopic lesions in the spinal cord (p < 0.05), and transient neurological deficits in the postoperatively (p < 0.05). Conclusions It is necessary to perform surgical planning and have several tips of the piezoelectric instrument available for the safe use of the piezoelectric device in neurosurgery.

ABSTRACT

ABSTRACT This article reports a combined technique of sutureless intrascleral fixated intraocular lens implantation and Descemet membrane endothelial keratoplasty in a patient with anterior pseudophakic bullous keratopathy. Two scleral tunnels were created, corneal incisions were made, and a foldable intraocular lens was cut and removed from the anterior chamber. After performing anterior vitrectomy, a 3-piece foldable intraocular lens was implanted into the anterior chamber. One of the intraocular lens haptics was grasped with a forceps and pulled out from the scleral tunnel. Then, the end of the haptic was cauterized. Similar maneuvers were applied for the other haptic. Next, an 8-mm-diameter donor tissue was prepared, and the recipient endothelial tissue was peeled and removed from the center of the recipient cornea. The prepared donor tissue was injected into the anterior chamber. After proper opening and placement of the donor tissue, an air bubble was injected below the tissue. There were no postoperative complications during the 1-month follow-up.


RESUMO Relato de uma técnica que combina o implante de uma lente intraocular com fixação intraescleral sem sutura e uma ceratoplastia endotelial da membrana de Descemet em paciente com ceratopatia bolhosa pseudofácica anterior. Foram criados dois túneis esclerais. Foram feitas incisões na córnea e a lente intraocular dobrável foi cortada e removida da câmara anterior. Foi então efetuada uma vitrectomia anterior e uma lente intraocular dobrável de 3 peças foi implantada na câmara anterior. Um dos hápticos da lente intraocular foi pinçado com um fórceps e puxado para fora do túnel escleral. A extremidade do háptico foi cauterizada. Manobras semelhantes foram feitas no outro háptico. Foi preparado um tecido de doador com 8 mm de diâmetro e o tecido endotelial da área receptora foi removido do centro da córnea. O tecido preparado do doador foi injetado na câmara anterior. Após abertura e posicionamento adequados do tecido do doador, foi injetada uma bolha de ar abaixo do tecido. Não foi observada nenhuma complicação pós-operatória durante um mês de acompanhamento.

ABSTRACT

We know Kocher's name as an anatomical reference in neurosurgery. In fact, Theodor Kocher was a Swiss general surgeon, and his contributions were such that Kocher was honored in 1909 with the Nobel Prize in Medicine and Physiology, and he was the first surgeon to receive this honor. Kocher participated in the initial scientific phase of medicine, livingwith names that are in history, as well as him; Langenbeck and Virchow, Lucke, Billroth, Horsley, Lister, Halstedt, Pasteur, Osler, Lawson Tait, Verneuil, and a long list and other icons of the time. The present account rescues the many important facets and contributions of the Swiss surgeonTheodor Kocher, and his relationship with several of them. Kocher's memory, surgical instruments and literary production are preserved in a small wing of the University of Bern. The present article highlights how intense Kocher's dedication to the medical field was.

ABSTRACT

Se narran los sucesos históricos más relevantes de la práctica de la especialidad de Oftalmología en la provincia de Matanzas y los relacionados con la formación de profesionales a partir de la década del 70 del siglo XX. Al utilizar el método de la narración histórica, se propició la reflexión sobre los propios acontecimientos y su relación con el contexto socio-económico al momento en que estos se produjeron; destacándolos como los antecedes y factores favorecedores del desarrollo de la Oftalmología en Matanzas. Este trabajo se realizó no sólo para narrar de manera cronológica la historia desde los inicios y creciente práctica local de la especialidad, sino también, como a manera de testimonio para las actuales y futuras generaciones, de cómo tributaron los profesionales, las instituciones y los propios eventos, al avance científico y al impacto social de la especialidad en Matanzas. Se concluye, que el comienzo del esplendor de la práctica de la Oftalmología en la provincia de Matanzas, se enmarca a la década del 70 del siglo pasado; y a los inicios del siglo XXI al de mayor desarrollo acumulado. Todo este salto de calidad en el tiempo y en el espacio, ha sido posible, gracias a las políticas de salud y educacionales implementadas por el Ministerio de Salud Pública del país (AU).


The authors recount the most relevant historical facts of the Ophthalmology practice in the province of Matanzas and those related to professionals´ training from the seventies of the XX century. Using the method of historical recount helped the reflection on the proper facts and their relation to the socio-economic context at the moment they took place, highlighting them as antecedents and factor favoring the development of Ophthalmology in Matanzas. The current paper was written not only to recount in a chronological way the history from the beginning and growing local practice of the specialty, but also as a testimony for the current and future generations to know how the professionals, institutions and events contributed to the scientific advance and to the social impact of the specialty in Matanzas. It is concluded that the beginning of the splendor of Ophthalmology practice in the province of Matanzas falls within the decade of the seventies of the past century, and the beginning of the XXI century is the time of the bigger accumulated development. All this quality jump in the time and space has been possible thanks to health and educational politics implemented by the Ministry og Public Health of the country (AU).

ABSTRACT

ABSTRACT Background: Robotic gastrectomy is gaining popularity worldwide. It allows reduced blood loss and lesser pain. However, it widespread use is limited by the extensive learning curve and costs. Aim: To describe our standard technique with reduced use of robotic instruments. Methods: We detail the steps involved in the procedure, including trocar placement, necessary robotic instruments, and meticulous surgical description. Results: After standardizing the procedure, 28 patients were operated with this budget technique. For each procedure material used was: 1 (Xi model) or 2 disposable trocars (Si) and 4 robotic instruments. Stapling and clipping were performed by the assistant through an auxiliary port, limiting the use of robotic instruments and reducing the cost. Conclusion: This standardization helps implementing a robotic program for gastrectomy in the daily practice or in one`s institution.


RESUMO Racional: A gastrectomia robótica está ganhando popularidade no mundo. Ela permite menor perda sanguínea e menos dor. Entretanto, a curva de aprendizado extensa e os custos limitam seu amplo uso. Objetivo: Descrever nossa técnica padrão com uso reduzido de instrumental robótico. Métodos: Detalham-se todos os passos envolvidos no procedimento, incluindo posicionamento de portais, instrumentos robóticos necessários e descrição cirúrgica meticulosa. Resultados: Após a padronização do procedimento, 28 pacientes foram operados com essa técnica. Em cada procedimento foram utilizados: 1 (modelo Xi) ou 2 (Si) trocárteres descartáveis e 4 pinças robóticas. Grampeamentos e colocação de clips ficaram a cargo do auxiliar, reduzindo o número de instrumentos robóticos utilizados, diminuindo assim o custo. Conclusão: Essa padronização ajuda a implementar programa robótico de gastrectomia na prática diária ou em uma instituição.

ABSTRACT

ABSTRACT Objective: Since its first report, video-assisted thoracic surgery (VATS) lung lobectomy was carried out with the use of conventional surgical instruments, used in laparoscopy and open thoracotomy. These instruments are expensive, not standardized and there are a variety of models and manufacturers. The aim of this study was to determine the impact of the use of these instruments on the experimental pulmonary lobectomy. Methods: We used a modified surgical simulator that uses a porcine heart-lung block filled with tomato sauce, and tested specific (Group 1) and regular (Group 2) instruments. Each group includes 15 experiments. Results: The median total time, excluding the time spent to correct the lesions, was 45.08 and 45.81 minutes, respectively in Group 1 and Group 2. There was no statistical difference between the total times (p=0.58). The only statistically different was seen for partial times regarding the elapsed time to cut and suture of lung fissures (p=0.03 and 0.04, respectively). There were more direct lesions and indirect leaks in Group 2, but without statistical significance (p=1.000 and p=0.203, respectively). The mean time spent for the diagnosis and correction of these events was 1.77 minutes with a standard deviation of 1.18 for Group 1 and 2.72 ± 1.11 minutes for Group 2 (p=0.044). Conclusion: The use of minimally invasive instruments is not associated with time improvement spent with experimental video-assisted lung lobectomy and does not lead to a faster or safer surgery. The use of VATS instruments makes correction of adverse events faster when they occur.


RESUMO Objetivo: desde os primeiros registros, a lobectomia pulmonar por cirurgia torácica videoassistida (CTVA) foi feita usando instrumentos convencionais e de laparoscopia. Recentemente instrumentais específicos para CTVA surgiram. Esses instrumentais têm custo elevado, não são padronizados existindo uma variedade de modelos e fabricantes. Buscou-se determinar o impacto do uso desses instrumentais na realização da lobectomia pulmonar superior esquerda experimental. Métodos: foi usado simulador modificado com bloco de coração-pulmões preenchidos com molho de tomate para testar o uso de instrumental dedicado de CTVA e de cirurgia convencional (Grupo 1 e Grupo 2, respectivamente). Cada grupo inclui 15 experimentos. Resultados: a mediana do tempo total, excluído o tempo para corrigir vazamentos, foi de 45,8 e 45,81 minutos, respectivamente para o Grupo 1 e Grupo 2. Não houve diferença estatisticamente significante entre os tempos totais (p=0,58). Os únicos tempos parciais estatisticamente diferentes foram os para cortar e suturar a fissura pulmonar (p=0,03 e 0,04, respectivamente). Ocorreram mais lesões diretas e vazamentos indiretos no Grupo 2, mas sem significância estatística (p=1,000 e 0,203, respectivamente). A média de tempo gasto para diagnosticar e corrigir os eventos de lesão e vazamento foi de 1,77 minutos com desvio padrão de 1,18 para o Grupo 1 e 2,72±1,11 minutos para o Grupo 2 (p=0,044). Conclusão: o uso de instrumentos para CTVA não torna a cirurgia mais rápida, nem mais segura. O uso de instrumentos de CTVA permitiu uma correção mais rápida dos eventos adversos ocorridos.

ABSTRACT

RESUMO A infecção pelo coronavírus determinante da doença COVID-19, também conhecida como SARS-COV2 foi classificada nos últimos meses como pandemia. Essa é potencialmente fatal, representando enorme problema de saúde mundial. A disseminação, após provável origem zoonótica na cidade de Wuhan, China, resultou em colapso do sistema de saúde de diversos países, alguns com enorme impacto social e número grande de mortes descritas na Itália e Espanha. Medidas extremas intra e extra-hospitalares têm sido implementadas a fim de conter a transmissão e disseminação da COVID-19. No âmbito cirúrgico, enorme quantidade de procedimentos considerados não essenciais ou eletivos foram prorrogados ou suspensos até resolução da pandemia. No entanto, cirurgias de urgência e oncológicas não permitem que o paciente espere. Nesta publicação, sugerimos e ensinamos adaptação a ser feita com materiais de uso corriqueiro em laparoscopias para evitar a contaminação ou a disseminação entre as equipes assistenciais e os pacientes.


ABSTRACT The coronavirus infection, also known as SARS-COV2, has proven to be potentially fatal, representing a major global health problem. Its spread after its origin in the city of Wuhan, China has resulted in a pandemic with the collapse of the health system in several countries, some with enormous social impact and expressive number of deaths as seen in Italy and Spain. Extreme intra and extra-hospital measures have been implemented to decrease the transmission and dissemination of the COVID-19. Regarding the surgical practice, a huge number of procedures considered non-essential or elective were cancelled and postponed until the pandemic is resolved. However, urgent and oncological procedures have been carried out. In this publication, we highlight and teach adaptations to be made with commonly used materials in laparoscopy to help prevent the spread and contamination of the healthcare team assisting surgical patients.
