RESUMO

ABSTRACT: Thoracoscopy is replacing open lung biopsies because it is less invasive, usually the technique is done using three portals and intracorporeal suture technique. This study described the feasibility and efficacy of a novel pre tied loop ligature and to propose a thoracoscopic access strategy with two portals to perform lung biopsy in patients under 5 kg. Ten rabbits were positioned in dorsal recumbency. Total thoracoscopic lung biopsy was performed using a combined transdiaphragmatic approach and a right intercostal approach. A pre tied loop ligature was placed to perform a caudal lung lobe biopsy. Insufflation of the thoracic cavity was not performed. The total surgery time was 41.4 ± 14.5 min. The procedure was carried out free of complications that prevented slippage or tightening the knot or that made it come loose after the lung biopsy; there was no serious complication during the surgical procedure. The samples obtained averaged 1x0.64x0.45 cm (Length, Width, Depth) and were considered satisfactory according to the histopathologic evaluation. Thorax radiographs taken before and after the surgeries were compared and showed no pneumothorax or hemothorax. Necropsy confirmed no knot failure occurred at the biopsy site. The use of the novel pre tied loop ligature is a safe and effective technique, avoiding problems with the limited size of the thoracic cavity in small patients.


RESUMO: A toracoscopia está substituindo as biópsias pulmonares abertas por ser menos invasiva. Usualmente a técnica é feita utilizando três portais e ligaduras feitas intra corporalmente. O objetivo deste estudo foi descrever a viabilidade e eficácia de uma nova ligadura com alça pré-amarrada e propor uma estratégia de acesso toracoscópico com dois portais para realizar biópsia pulmonar em pacientes com menos de 5kg. Dez coelhos foram posicionados em decúbito dorsal. A biópsia pulmonar por toracoscopia total foi feita pela abordagem combinada transdiafragmática e abordagem intercostal direita. Uma nova ligadura pré-amarrada foi colocada para realizar uma biópsia do lobo pulmonar caudal. Não foi realizada insuflação da cavidade torácica. O tempo total de cirurgia foi de 41,4 ± 14,5 min. Os procedimentos foram realizados sem complicações que impedissem o escorregamento ou aperto do nó ou que o soltassem após a biópsia pulmonar; não houve nenhuma intercorrência grave durante o procedimento cirúrgico. As amostras coletadas tinham tamanho médio 1x0,64x0,45 cm e foram consideradas satisfatórias de acordo com a avaliação histopatológica. As radiografias de tórax feitas antes e depois das cirurgias foram comparadas e não mostraram pneumotórax ou hemotórax. A necropsia confirmou que não ocorreu falha do nó no local da biópsia. Conclui-se que uso da nova ligadura com alça pré-amarrada é uma técnica segura e eficaz, evitando problemas com o tamanho limitado da cavidade torácica em pacientes pequenos.

RESUMO

INTRODUCCIÓN: En las últimas décadas es creciente el abordaje por mínima invasión de patologías abdominales debido a sus beneficios evidentes. El cuadro apendicular es la principal emergencia quirúrgica, con diferentes métodos del cierre de la base apendicular. En este artículo comparamos dicho cierre con engrapadora lineal o ligadura con lazo hemostático, para analizar la frecuencia de complicaciones como absceso, dehiscencia y seroma. MÉTODO: Se realizó un estudio prospectivo, observacional y descriptivo, con un total de 703 procedimientos, empleando en 567 pacientes ligadura con lazo hemostático y en 136 engrapadora lineal, operados por los mismos cirujano y equipo quirúrgico, con curva de aprendizaje concluida. RESULTADOS: Las complicaciones referidas en el presente estudio son absceso (n = 5), dehiscencia (n = 3) y seroma (n = 3). De acuerdo con las fases de la patología apendicular: fase 1 o apéndice congestivo, no presentaron complicaciones; fase 2 o supurativo, se reportó un caso de dehiscencia de herida quirúrgica con el uso de ligadura con lazo hemostático; fase 3 o necrótico, se reportó un caso de seroma en un paciente tratado con ligadura con lazo hemostático; y fase 4 o perforado, se encuentra diferencia significativa en el caso de abscesos, reportando cinco con el uso de ligadura con lazo hemostático y ninguno con engrapadora lineal. CONCLUSIONES: En nuestro estudio no existe diferencia estadísticamente significativa entre el uso de engrapadora lineal o ligadura con lazo hemostático en las fases apendiculares 1-3; en la fase 4 es de utilidad significativa el uso de engrapadora lineal ante la incidencia de abscesos. INTRODUCTION: In the last decades, the approach by minimally invasive surgery of abdominal pathologies is growing due to its evident benefits; the appendicular cases being the main surgical emergency, with different methods of closing the appendicular base. In this article, we compared the appendicular base closure with linear stapler and endoloop, to analyze the frequency of complications such as abscess, dehiscence and seroma. METHOD: A prospective, observational and descriptive study was conducted, with a total of 703 procedures, using 567 endoloop patients and 136 linear stapler, operated by the same surgeon and surgical team, with a completed learning curve. RESULTS: The complications referred in the present study were patients with abscess (n = 5), dehiscence (n = 3) and seroma (n = 3). According to the phases of the appendiceal pathology: phase 1 or congestive appendix did not present complications; phase 2 or suppurative was reported one case of surgical wound dehiscence in the use of endoloop; in phase 3 or necrotic, one case of seroma was reported in a patient treated with endoloop; while in phase 4 or perforated there is a significant difference in the case of abscesses, reporting five in the use of endoloop and none in the case of a linear stapler. CONCLUSIONS: In our study there is no statistically significant difference between the use of linear stapler or endoloop in the early appendicular phases; being of significant utility in Phase 4 the use of linear stapler for the incidence of abscesses.

RESUMO

Background: Ovariectomy(OVE) and ovariohysterectomy (OVH) are the most performed surgical procedures in Veterinary Medicine. In videosurgery, both in stray animals at sterilization campaigns and in the increasing demand of tutors to perform the technique. Laparoscopy results in reduced tissue damage, due to minimal organ manipulation and surgical access hemostasis can be performed by several methods, such as electro-coagulation, clips, and intra and extracorporeal ligatures. A pre-tied ligature system, or endoloop, is a haemostatic technique comprised of a slipknot and knot pusher, which is inserted into the abdominal cavity through one of the laparoscopic ports. The aim of this study was to describe a novel OVE technique in cats, in which haemostasis was performed using miniloop, aimed at reducing the number of ports needed for knot tying.Material, Methods & Results: Ten healthy not spayed female cats, aged 6 months to 5 years, were selected for this study. They were submitted to an OVE using miniloop as haemostasis method. Access to the peritoneal cavity was through two 5 mm ports on the midline of the ventral abdomen, 5 cm apart, with one immediately caudal to the umbilical scar and the other in between the last pair of teats. The first trocar was inserted at the caudal incision using the Hasson technique and a 5 mm zero-degree optics attached to a camera was introduced through it. The placement of the second access port was video assisted. For ovary exposure, the patients were positioned in lateral recumbency on the contralateral side to the ovary being removed. The miniloop was composed of a 2 mm diameter minitrocar, a 1.8 mm knot pusher, and a pre-tied slipknot. It was introduced percutaneously at the lateral abdominal wall. It was inserted attached to a pre-tied loop ligature.[...]

RESUMO

La polipectomía es un procedimiento muy común en endoscopia que no está exento de complicaciones; la más frecuente es el sangrado posterior al procedimiento por lo que se han desarrollado para su prevención numerosas estrategias; una de ellas es el uso de endoloop que ha mostrado buenos resultados para pólipos de pedículo muy largo o grueso. Sin embargo, los kits comerciales para realizar este procedimiento son muy costosos y poco disponibles, lo que hace que en nuestro medio se use muy poco. Aquí presentamos un diseño artesanal de bajo costo diseñado (por el grupo del doctor Sakai en Sao Pablo, Brasil) y la experiencia en nuestro servicio con este.


Although polypectomies are very common procedures in endoscopy, they are not without complications. The most common complication is bleeding following the procedure. Numerous strategies have been developed to prevent bleeding. One of these, the use of an endoloop, has had good results for polyps with very long or thick pedicles. Nevertheless, since commercial endoloop kits for this procedure are very expensive and in short supply, they are not widely used in Colombia. In this article we present a low cost design developed by Dr. Sakai in Sao Paul Brazil for an endoloop that can be made in house, and we present our experience with this tool.

RESUMO

Conceitualmente, hemorragia digestiva alta (EDA) é definida como qualquer sangramento de localização proximal ao ângulo de Treitz na prática originária do esôfago, estômago e duodeno. Apesar dos avanços, tanto na área diagnóstica quanto terapêutica, a hemorragia digestiva continua sendo uma importante causa de morbimortalidade, com alta incidência e de grande impacto econômico. Mesmo com novas técnicas endoscópicas, a mortalidade permanece elevada com o passar dos anos. No presente artigo, relatamos o caso de uma paciente de 80 anos de idade que deu entrada em nosso serviço, referindo 2 episódios de hematêmeses nas 12 horas que antecederam à admissão hospitalar. Após estabilização hemodinâmica, foi submetida à EDA que revelou grande pólipo gástrico, sem sinais de sangramento ativo. Optou-se por terapia mecânica hemostática combinada (endoloop e hemoclips), com sucesso. Porém houve ressangramento da lesão, com instabilidade hemodinâmica, e a segunda tentativa de hemostasia mecânica foi associada à correção do INR com plasma, já que a paciente fazia uso crônico de warfarin devido à fibrilação atrial crônica. Paciente evoluiu bem, tendo alta após 3 dias da segunda abordagem endoscópica. Estudos recentes evidenciam que a terapia combinada é mais efetiva do que a monoterapia no controle das hemorragias digestivas altas. No presente caso, optamos por dois métodos mecânicos, com êxito somente após a segunda abordagem. Neste caso, a coagulopatia foi o principal fator predisponente na ocorrência do ressagramento. Portanto sempre se deve atentar para sua correção em casos em que se acredite que a alteração possa influenciar negativamente no prognóstico.


Conceptually, upper gastrointestinal bleeding is defined as any bleeding located proximal to the angle of Treitz, originating from the esophagus, stomach and duodenum. Despite advances in the diagnostic and therapeutic methods, gastrointestinal bleeding remains a important cause of morbidity and mortality, with high incidence and economic impact. Even with new endoscopic techniques, mortality remains high over the years. In this article, we report a case of a 80-year-old woman who was admitted in our hospital, referring 2 episodes of hematemeses, 12 hrs before the admission. After hemodynamic stabilization, we submit de patient to a EGD that revealed a large gastric polyp with no signs of active bleeding. We chose a combined therapy, mechanical and haemostatic (end loop and hem clips), successfully. But after this, there was rebreeding, hemodynamic instability, and a second attempt was tried. In the second approach we associated mechanical therapy to correction of INR with plasma, since the patient had chronic use of warfare due to chronic atria fibrillation. Patient recovered well and was discharged three days after the second endoscopic approach. Recent studies show that combined therapy is more effective than monoterapia in controlling high digestive bleeding. In this case we chose two mechanical methods, successfully only after the second approach. In this case the coagulopathy was the main predisposing factor in the rebleeding occurrence. Therefore we must always be attentive to its correction in cases where we believe that it can negatively influence the prognosis.

RESUMO

Introducción: las neoplasias pediculadas del colon comprenden lesiones epiteliales y no epiteliales, dependiendo de su crecimiento pueden presentar un pedículo largo y grueso. El tratamiento endoscópico de estas lesiones representa un reto para el endoscopista, por lo que se han descrito diversas técnicas para minimizar las complicaciones. Objetivo: evaluar el uso de un endoloop de fabricación no comercial en el tratamiento endoscópico de las neoplasias pediculadas del colon. Pacientes y métodos: entre enero y abril de 2012 se escogieron pacientes sometidos a colonoscopia de rutina que presentaron neoplasias con pedículos grandes y largos para realizar resección endoscópica previa ligadura de la base con endoloop de fabricación no comercial (elaborado con asa de polipectomía y lazo de nylon con nudo corredizo). Se evaluó tiempo del procedimiento, tipo de neoplasia, ubicación, complicaciones inmediatas y tardías. Resultados: se seleccionaron 4 pacientes de un total de 110 sometidos a colonoscopia de rutina (3,6 %), media de edad: 53,25 años, todos del sexo masculino, el tipo de neoplasia más frecuente: pólipo adenomatoso pediculado, la ubicación más frecuente fue colon sigmoides, se realizó resección completa de las lesiones, no se encontraron complicaciones inmediatas ni tardías. Conclusión: el endoloop de fabricación no comercial es una herramienta útil para el control de la base en lesiones neoplásicas con pedículos grandes y largos, incluso en aquellas de tipo no epitelial.


Introduction: Pedunculated colonic neoplasms include epithelial and non-epithelial lesions, depending on their growth may to have a large and long pedicle. Management of this lesions represent a challenge for the endoscopist, due this, many techniques have been described to minimize complications. Objective: This trial aims to evaluate the use of a non-factory endoloop in the endoscopic treatment of pedunculated neoplasms of the colon. Methods: Between January and April 2012 patients undergoing routine colonoscopy who had tumors with large and long pedicle were selected to perform endoscopic resection after base ligation with non-factory endoloop (made Cook Medical AcuSnare G22629 detachable standard oval and nylon loop with roeder's knot). Procedure time was evaluated, tumor type, location, immediate and late complications. Results: 4 patients were selected from a total of 110 undergoing routine colonoscopy (3.6 %), the mean age was 53.25 years, all males, the most common type of tumor was pedunculated adenomatous polyp, the most common location was the sigmoid colon, complete resection of the lesion was performed, there was no immediate or late complications. Conclusion: non-factory endoloop is a useful tool for the base control of neoplasm with large and long pedicle, including those non-epithelial.

RESUMO

Los pólipos gástricos suelen ser hiperplásicos y benignos en su gran mayoría. Se asocian entre otras a factores idiosincráticos, genéticos o al uso prolongado de bloqueadores de bomba. Si bien su grado de malignización es bajo se recomienda su remoción. La mayoría se encuentran incidentalmente en procedimientos de rutina. Cuando superan los 10 mm (pueden incluso llegan a medir varios centímetros) suelen causas dispepsia, pueden sangrar u obstruir el píloro si son ubicados en antro. Reportamos la remoción de un pólipo gástrico gigante con método combinado de inyección, elevación, uso de asa desprendible o endoloop, complementado con aplicación de argón plasma (APC).


Gastric polyps are mainly hyperplastic and benign. They are associated with idiosinchratic factors, genetic or associated to chronic use of pump inhibitors. Endoscopic resection is recommended eventhough the rate of malignant transformation is very low. The vast majority are encountered as incidental findings in routine endoscopy. When they grow beyond 10mm (they may reach several centimetres in diamater) gastric polyps are a cause of dyspepsia, bleeding or gastric outlet obstruction, if located in the antrum. We report a safe endoscopic resection of a giant gastric polyp combining injection, elevation, endoloop and argon plasma coagulation (APC).
