ABSTRACT

ABSTRACT Ophthalmologic complications of nonocular surgeries are rare events, but can lead to irreversible conditions of low visual acuity. They are often associated with spine, heart and neck surgery, however they can occur after procedures on other systems. The main local causes are ischemic optic neuropathies, vascular occlusions, cortical lesions, and acute angle-closure glaucoma. We report two cases of sudden low visual acuity secondary to vascular occlusions after gastrointestinal procedures. In the first case, a 57-year-old patient electively admitted for colon reconstruction after Hartmann's colostomy, progressed with intra- and postoperative complications and required subsequent complementary surgeries. Once month later he presented with sudden bilateral low visual acuity, painless and non-altitudinal, and was diagnosed as papillophlebitis, which resolved spontaneously with the progression of the condition. The second case, a 69-year-old patient with no comorbidities underwent rectal resection due to suspected malignant tumor, and progressed on the third postoperative day, with pain and bilateral low visual acuity secondary to acute angle-closure glaucoma, and branch retinal artery occlusion in right eye; treated with iridotomy and ocular hypotensive eye drops, with only slight recovery of vision. The article aims to discuss the etiological mechanisms of the reported conditions and present a literature review.


RESUMO Complicações oftalmológicas de cirurgias não oculares são raras, mas podem levar a condições irreversíveis de baixa acuidade visual. Em geral são associadas à cirurgia de coluna, coração ou pescoço, mas podem ocorrer após procedimentos em outros sistemas. As principais causas são neuropatias ópticas isquêmicas, oclusões vasculares, lesões corticais, e glaucoma agudo de ângulo fechado. Relatamos dois casos de baixa acuidade visual súbita, secundária a oclusões vasculares, após procedimentos cirúrgicos gastrointestinais. No primeiro caso, um paciente de 57 anos foi internado de forma eletiva para reconstrução do cólon após colostomia de Hartmann. Evoluiu com complicações nos períodos intra- e pós-operatório, e necessitou de outras cirurgias complementares. Um mês depois apresentou baixa acuidade visual bilateral súbita, indolor e não altitudinal, e foi diagnosticado como papiloflebite, com resolução espontânea na evolução. O segundo caso, uma paciente de 69 anos, sem comorbidades, foi submetida à ressecção do reto por suspeita de tumor maligno e, no terceiro dia de pós-operatório, evoluiu com dor e baixa acuidade visual bilateral, secundária a glaucoma agudo de ângulo fechado, e oclusão de ramo da artéria retiniana no olho direito; tratada com iridotomia e colírios hipotensores, com recuperação parcial da visão. O objetivo do artigo é discutir os mecanismos etiológicos das doenças relatadas, e apresentar uma revisão da literatura.

ABSTRACT

ABSTRACT Background: laparoscopy surgery has many proven clinical advantages over conventional surgery and more recently, robotic surgery has been the emerging platform in the minimally invasive era. In the colorectal field, although overcoming limitations of standard laparoscopy, robotic surgery still faces challenging situations even by the most experienced colorectal surgeons. This study reports essentials technical aspects and comparison between Da Vincis Si and Xi platforms aiming to master and maximize efficiency whenever performing robotic colorectal surgery. Methods: this study overviews the most structured concepts and practical applications in robotic colorectal surgery in both Si and Xi Da Vinci platforms. Possible pitfalls are emphasized and step-wise approach is described from port placement and docking process to surgical technique. We also present data collected from a prospectively maintained database. Results: our early experience includes forty-four patients following a standardized total robotic left-colon and rectal resection. Guided information and practical applications for a safe and efficient robotic colorectal surgery are described. We also present illustrations and describe technical aspects of a standardized procedure. Conclusion: performing robotic colorectal surgery is feasible and safe in experienced surgeons hands. Although the Da Vinci Xi platform demonstrates greater versatility in a more user-friendly design with technological advances, the correct mastery of technology by the surgical team is an essential condition for its fully robotic execution in a single docking approach.


RESUMO Introdução: a cirurgia laparoscópica demonstrou vantagens sobre a cirurgia convencional e, mais recentemente, a cirurgia robótica tem sido a plataforma emergente na era cirúrgica minimamente invasiva. Na prática colorretal, embora supere as limitações da laparoscopia, a cirurgia robótica ainda enfrenta situações desafiadoras, mesmo diante de cirurgiões colorretais experientes. Este estudo relata aspectos técnicos essenciais e comparação entre as plataformas Si e Xi Da Vinci com o objetivo de auxiliar e maximizar a eficiência na realização de cirurgia robótica colorretal regrada. Métodos: este estudo apresenta uma visão geral dos conceitos essenciais e aplicações práticas em cirurgia robótica colorretal nas plataformas Da Vinci Si e Xi. As potenciais dificuldades são enfatizadas e uma abordagem em etapas é descrita desde a colocação dos portais e seu processo de docking até a técnica cirúrgica. Também apresentamos brevemente dados coletados de um banco de dados mantido de forma prospectiva. Resultados: nossa experiência inicial inclui quarenta e quatro pacientes submetidos à cirurgia totalmente robótica padronizada na ressecção colônica e retal. Informações e aplicações práticas para uma cirurgia robótica colorretal segura e eficiente são descritas. Também são apresentadas ilustrações e dados breves da experiência.

ABSTRACT

Resumen Las fístulas anorrectales complejas son un desafío para el coloproctólogo. Son una patología frecuente que afecta la calidad de vida de los pacientes. La patogénesis aún no está clara, estarían involucradas citoquinas y el proceso de transición de epitelio a mesénquima. El gold standard para su estudio es la resonancia nuclear magnética, su uso por sí mismo disminuye la recurrencia. El objetivo del tratamiento es lograr la curación sin afectar la función del esfínter evitando las recidivas. Existen múltiples técnicas, siendo la de mayor aceptación la ligadura interesfinteriana del trayecto fistuloso, con tasa de curación sobre el 70%, con mínimo impacto en continencia. Esta revisión incluye otras técnicas como el colgajo endorrectal de avance, uso de sellante, permacol, células madres, Anal fistula plug, Video asisted anal fistula treatment, Over the scope clip y fistula laser closure.


Complex anal fistula are a challenge for colorectal surgeons. It is a common pathology in population. Pathogenesis is still unclear, it would be involved citokines and the process of epitelial to eesenchymal transition. The gold standard for study is MRI, its use reduces recurrences. The goal of treatment is heal the fistula without damaging the function of the sphincter and avoid recurrences. There are multiple techniques, the most accepted is ligation of intersphincteric fistula tract with cure rate over 70%, with minimal impact in continence. This review includes other techniques like rectal advancement flap, fibrin glue, permacol, stem cells, anal fistula plug, video asisted anal fistula treatment, over the scope clip and fistula laser closure.

ABSTRACT

Resumen El cáncer gástrico es una patología de alta incidencia en Chile. Afortunadamente es baja la incidencia de márgenes R1 cuando se realiza una cirugía con intención curativa. Al tener un tumor subcardial o cardial es perentorio realizar una biopsia rápida (intraoperatoria), en caso que ésta resulte positiva, es difícil tomar una decisión sobre qué realizar a continuación, ya que el realizar una esofagoyeyunoanastomosis intratorácica aumenta el riesgo quirúrgico. Para esto, es de suma importancia tener la información de las características histopatológicas del tumor, el riesgo de filtración, la recurrencia, la sobrevida, las terapias adyuvantes y la realidad país. Se realizó una revisión de la literatura con el fin de poder guiar la toma de decisiones.


Gastric cancer is a pathology with a high incidence in Chile, fortunately, the incidence of R1 margins is low when performing surgery with curative intent. When having a sub cardial or cardial tumor, it is essential to perform a rapid (intraoperative) biopsy, if this is positive when cutting the esophagus just under the pillars, it is difficult to make the decision of what to do next, since performing an inthrathoracic esophagojejunostomy increases the surgical risk. For this, it is very important to have information about the histopathological characteristics of the tumor, the leakage risk, there currence, the survival, the adjuvant therapies and the reality of the country. A review of the literature was done in order to guide the decisions.

ABSTRACT

La endometriosis es una de las patologías ginecológicas benignas más frecuente, ocurre en un 7-10% de las mujeres en edad reproductiva y es causal de dolores crónicos e infertilidad. Se trata de una población joven y sana por lo demás. La sospecha diagnóstica de esta entidad debe ser alta y su manejo multidisciplinario.La endometriosis colorrectal representa una variable altamente incapacitante y es aquí donde se plantea la necesidad de un tratamiento más agresivo para su resolución. Frente a esto nos preguntamos, ¿qué rol tiene la cirugía?, ¿cuáles serían sus ventajas y desventajas?, ¿por qué deberíamos elegirla como método terapéutico?.La presente monografía fue inspirada en todas las pacientes que nos plantearon esta controversia. Que motivaron interconsultas, ateneos, búsqueda de bibliografía. Que generaron discusiones, dudas e incertidumbres y nos hicieron salir del rol de cirujanos al que estamos habituados y nos enseñaron a acompañar, cuando no pudimos curar

ABSTRACT

ABSTRACT Background: Several types of complications including constipation, fecal soiling, perianal excoriation, were reported among different types of surgery for Hirschsprung's disease. Aim: To compare circular and oblique anastomoses following Soave's procedure for the treatment of Hirschsprung's disease. Methods: Children who underwent Saove's pull through procedure with oblique and circular anastomoses were included. Duration of the follow up was two years after surgery. Postoperative complications, such as wound infection, wound dehiscence, peritonitis, fecal soiling, perianal excoriation, were recorded for each patient. Results: Thirty-eight children underwent oblique anastomoses. Circular ones were done for 32 children. Perianal excoriation was seen in 57.89% and 46.87% of children in oblique and circular group, respectively. Enterocolitis was more frequent in circular (40.62%) than oblique (28.94%) group. Anastomotic stricture was more frequent in circular (15.62%) than oblique (7.89%). Conclusion: Perianal excoriation was the most common complication among patient in both groups. Oblique anastomoses had fewer complications than circular, and may be appropriate option for patient who underwent Soave's procedure.


RESUMO Racional: Vários tipos de complicações, incluindo constipação, secreção fecal, escoriação perianal foram relatadas entre diferentes tipos de operações para a doença de Hirschsprung. Objetivo: Comparar as anastomoses circulares e oblíquas realizadas no procedimento de Soave para o tratamento da doença de Hirschsprung. Métodos: Neste estudo, foram incluídas crianças submetidas ao procedimento pull-through de Saove com anastomoses oblíquas e circulares. A duração do acompanhamento foi de dois anos no pós-operatório. Complicações, como infecção da ferida, deiscência da ferida, peritonite, secreção fecal, escoriação perianal foram registradas para cada paciente. Resultados: Trinta e oito crianças foram submetidas à anastomoses oblíquas. As circulares foram realizadas em 32. Escoriação perianal foi observada em 57,89% e 46,87% das crianças nos grupos oblíquo e circular, respectivamente. Enterocolite foi mais frequente no grupo circular (40,62%) do que oblíquo (28,94%). A estenose anastomótica foi mais frequente na circular (15,62%) do que na oblíqua (7,89%). Conclusão: A escoriação perianal foi a complicação mais comum entre os pacientes nos dois grupos. A anastomose oblíqua teve menos complicações do que a anastomose circular e pode ser a opção adequada para o paciente submetido ao procedimento de Soave.

ABSTRACT

ABSTRACT Background: The Hartmann procedure remains the treatment of choice for most surgeons for the urgent surgical treatment of perforated diverticulitis; however, it is associated with high rates of ostomy non-reversion and postoperative morbidity. Aim: To study the results after the Hartmann vs. resection with primary anastomosis, with or without ileostomy, for the treatment of perforated diverticulitis with purulent or fecal peritonitis (Hinchey grade III or IV), and to compare the advantages between the two forms of treatment. Method: Systematic search in the literature of observational and randomized articles comparing resection with primary anastomosis vs. Hartmann's procedure in the emergency treatment of perforated diverticulitis. Analyze as primary outcomes the mortality after the emergency operation and the general morbidity after it. As secondary outcomes, severe morbidity after emergency surgery, rates of non-reversion of the ostomy, general and severe morbidity after reversion. Results: There were no significant differences between surgical procedures for mortality, general morbidity and severe morbidity. However, the differences were statistically significant, favoring primary anastomosis in comparison with the Hartmann procedure in the outcome rates of stoma non-reversion, general morbidity and severe morbidity after reversion. Conclusion: Primary anastomosis is a good alternative to the Hartmann procedure, with no increase in mortality and morbidity, and with better results in the operation for intestinal transit reconstruction.


RESUMO Racional: O procedimento a Hartmann permanece sendo o tratamento de escolha da maioria dos cirurgiões para o tratamento cirúrgico de urgência da diverticulite perfurada, entretanto está associado com altas taxas de não reversão da ostomia e de morbidade pós-operatória. Objetivo: Estudar os resultados após o procedimento de Hartmann vs. ressecção com anastomose primária, com ou sem ileostomia, para o tratamento da diverticulite perfurada com peritonite purulenta ou fecal (grau de Hinchey III ou IV), e comparar as vantagens entre as duas formas de tratamento. Método: Busca sistemática na literatura de artigos observacionais e randomizados comparando ressecção com anastomose primária vs. procedimento de Hartmann no tratamento de urgência da diverticulite perfurada. Analisar como desfechos primários a mortalidade após a operação de urgência e a morbidade geral após ela; como desfechos secundários, a morbidade severa após a operação de urgência, as taxas de não reversão da ostomia, a morbidade geral e severa após a reversão. Resultados: Não houve diferenças significativas entre os procedimentos cirúrgicos para mortalidade, morbidade geral e morbidade severa. Contudo, as diferenças foram significativas estatisticamente favorecendo anastomose primária na comparação com procedimento de Hartmann nos desfechos taxas de não reversão do estoma, morbidade geral e morbidade severa após reversão. Conclusão: A anastomose primária apresenta-se como boa alternativa ao procedimento de Hartmann, sem aumento de mortalidade e morbidade, e com melhores resultados na operação de reconstrução do trânsito intestinal.

ABSTRACT

ABSTRACT Background: There is still a need for progress in the treatment of transsphincteric anal fistulae and the use of herbal medicines seems promising. Aim: To evaluate the efficacy of Stryphnodendron adstringens associated with fistulotomy and primary sphincteroplasty in the treatment of transsphincteric fistulae in rats. Methods: Thirty Wistar rats were used, which were submitted to transsphincteric fistulas with steel wire 0; after 30 days a treatment was performed according to the group. Group A (n=10) was submitted to fistulotomy; group B (n=10), fistulotomy followed by primary sphincteroplasty with "U" stitch with polyglactin 911 4-0; group C(n=10) , similar to group B, but with the interposition between the muscular stumps of hemostatic sponge soaked in Stryphnodendron adstringens extract. Euthanasia was performed after 14 days, resecting a segment of the anal canal for histological analysis, which aimed to evaluate the closure of the fistula, the area of separation of the muscle cables, the inflammatory process and the degree of fibrosis. Results: No animal had a remaining fistulous tract. About the spacing between the muscle cables, an average of 106.3 µm2 was observed in group A, 82.8 µm2 in group B and 51.8 µm2 in group C (p<0.05). There was no difference between the groups regarding the inflammatory process and, in relation to fibrosis, in group A there was a mean of 0.6, in group B 0.7 and in group C 0.2 (p<0.05). Conclusions: Stryphnodendron adstringens extract was able to allow less spacing between muscle cables in rats submitted to fistulotomy followed by primary sphincteroplasty, in addition to providing less local fibrosis.


RESUMO Racional: Há ainda necessidade de avanço no tratamento das fístulas transesfincterianas e o uso de fitoterápicos parece promissor. Objetivo: Avaliar a eficácia da Stryphnodendron adstringens associada à fistulotomia e esfincteroplastia primária no tratamento de fístulas transesfincterianas em ratos. Métodos: Utilizou-se 30 ratos Wistar submetidos à confecção de fístulas transesfincterianas com fio de aço 0; após 30 dias realizou-se tratamento de acordo com o grupo. O grupo A (n=10) foi submetido à fistulotomia; o grupo B (n=10) fistulotomia seguida de esfincteroplastia primária com ponto em "U" com poliglactina 911 4-0; o grupo C (n=10), semelhante ao grupo B, porém com a interposição entre os cotos musculares de esponja hemostática embebida em extrato de Stryphnodendron adstringens. Realizou-se eutanásia após 14 dias, ressecando-se segmento do canal anal para análise histológica, que objetivou avaliar o fechamento da fístula, a área de afastamento dos cabos musculares, o processo inflamatório e o grau de fibrose. Resultados: Nenhum animal apresentou trajeto fistuloso remanescente. Quanto ao afastamento entre os cabos musculares observou-se média 106,3 µm2 no grupo A, 82,8 µm2 no grupo B e 51,8 µm2 no grupo C (p<0,05). Não houve diferença entre os grupos quanto ao processo inflamatório e, em relação à fibrose; no grupo A observou-se média 0,6, no grupo B 0,7 e no grupo C 0,2 (p<0,05). Conclusões: O extrato de Stryphnodendron adstringens foi capaz de permitir menor afastamento entre os cabos musculares em ratos submetidos à fistulotomia seguida por esfincteroplastia primária, além de proporcionar menor fibrose local.

ABSTRACT

ABSTRACT Background: The small-bowel is the most difficult segment to be visualized by traditional endoscopic methods. The need for its exploration led to the development of capsule endoscopy. The percentage of the complete examination varies and still remains uncertain the factors that influence the complete and incomplete examination. Aim: Evaluate the factors that interfere with the completeness of the endoscopic evaluation by the capsule. Methods: A prospective study in which were included 939 patients divided into two groups: complete group (CG) and incomplete group (IG). The studied variables that could interfere were: age, gender, comorbidities, diagnosis of Crohn's disease, previous abdominal surgery, inadequate preparation to compare the groups reached and did not reach the cecum. Results: Of the 939 patients included 879 (93.3%) reached the cecum (CG) and 63 (6.7%) IG no. The IG was composed of 29 (46.0%) men and 34 (54.0%) women with a mean age of 49.7 years; comorbidities this group accounted for 46% of which 15.9% was Crohn's disease, previous abdominal surgery 22.2% and 17.5% inadequate preparation. Conclusion: Factors associated with complete or incomplete outcome of the examination with capsule endoscopy were: associated comorbidities, Crohn's disease, previous abdominal surgery and inadequate preparation.


RESUMO Racional: O intestino delgado é segmento de maior dificuldade na visualização pelos métodos endoscópicos tradicionais. A necessidade de explorá-lo levou ao desenvolvimento da cápsula endoscópica. A porcentagem do exame completo por ela varia e falta identificar fatores que influenciam o exame completo e incompleto. Objetivo: Avaliar os fatores que interfiram na completude do estudo endoscópico pela cápsula. Método: Estudo prospectivo onde foram incluídos 939 pacientes divididos em dois grupos: grupo completo (GC) e grupo incompleto (GI). As variáveis analisadas que pudessem interferir foram: idade, gênero, comorbidades associadas, diagnóstico de doença de Crohn, operações abdominais prévias, preparo inadequado para comparar os grupos que atingiram e não atingiram o ceco. Resultados: Dos 939 pacientes incluídos 879 (93,3%) atingiram o ceco (GC) e 63 (6,7%) GI não. O GI era composto por 29 (46,0%) homens e 34 (54,0%) mulheres com idade média de 49,7 anos; as comorbidades deste grupo corresponderam a 46%, das quais 15,9% era doença de Crohn, 22,2% operação abdominal prévia e 17,5% preparo inadequado. Conclusão: Os fatores associados ao desfecho completo ou incompleto do exame com a cápsula endoscópica foram: comorbidades associadas, doença de Crohn, operação abdominal prévia e preparo inadequado.

ABSTRACT

ABSTRACT Background: Transanal haemorrhoidal dearterialization with mucopexy (THD-M) is a valuable option for treating patients with haemorrhoidal disease. However, there is still controversy with regard to its efficacy for more advanced grades. Aim: To evaluate the effectiveness of THD-M technique for treating hemorrhoidal disease and to compare the immediate and late results in different grades. Method: Seven hundred and five consecutive patients with Goligher's grade II, III or IV symptomatic haemorrhoids underwent surgical treatment using the THD-M method in five participating centres. Six well-trained and experienced surgeons operated on the patients. Average follow-up was 21 months (12-48). Results: Intraoperative complications were observed in 1.1% of cases, including four cases of haematoma, two of laceration of the mucosa, and two of bleeding. All of these were controlled by means of haemostatic suturing. In relation to postoperative complications, the most common of these were as follows: transitory tenesmus (21.4%); pain (7.2%); mucosal or haemorrhoidal prolapse (6.4%); residual skin tag (5.6%); faecal impaction (3.2%); haemorrhoidal thrombosis (2.8%); bleeding (2.1%); anal fissure (0.7%); and anal abscess (0.3%). Most of the complications were treated conservatively, and only 7.5% (53/705) required some type of surgical approach. There was no mortality or any severe complications. The recurrence of prolapse and bleeding was greater in patients with grade IV haemorrhoidal disease than in those with grade III and II (26.54% and 7.96% vs. 2.31% and 0.92% vs. 2.5% and 1.25%), respectively. Conclusion: The THD-M method is safe and effective for haemorrhoidal disease grades II and III with low rates of surgical complications. However, for grade IV hemorrhoids, it is associated with higher recurrence of prolapse and bleeding. So, THD-M method should not be considered as an effective option for the treatment of grade IV hemorrhoids.


RESUMO Racional: A desarterialização hemorroidária transanal associada à mucopexia (THD-M) tem sido indicada como alternativa à hemorroidectomia convencional para o tratamento da doença hemorroidária nos seus variados graus. No entanto, ainda hoje existe controvérsia com relação a sua eficácia para os graus mais avançados. Objetivo: Avaliar a eficácia da técnica THD-M para tratamento doença hemorroidária e comparar os resultados imediatos e tardios nos diferentes graus. Método: Entre julho de 2010 e setembro de 2015, 705 pacientes consecutivos com hemorroidas sintomáticas de graus II, III e IV foram submetidos ao tratamento cirúrgico pelo método THD-M e acompanhados por um período médio de 21 meses (12-48). As operações foram realizadas por seis cirurgiões com experiência em cirurgia colorretal, em três estados brasileiros. Resultados: Complicações intraoperatórias foram observadas em 1,1% dos casos, incluindo quatro casos de hematoma, dois de laceração da mucosa e dois de sangramento. Todos foram controlados com sutura hemostática. As complicações pós-operatórias mais comuns foram: tenesmo transitório (21,4%); dor (7,2%); prolapso mucoso ou hemorroidário (6,4%); plicoma residual (5,6%); impactação fecal (3,2%); trombose hemorroidária (2,8%); sangramento (2,1%); fissura anal (0,7%) e abscesso anal (0,3%). Não houve casos de complicações severas ou mortalidade perioperatória. A recorrência do prolapso e sangramento foi maior na doença hemorroidária grau IV do que nos graus III e II (26.54% e 7.96% vs. 2.31% e 0.92% vs. 2.5% e 1.25%; p<0,001), respectivamente. Conclusão: O método THD-M é seguro e efetivo no tratamento da doença hemorroidária nos graus II e III com baixo índice de complicações. No entanto, para a doença hemorroidária de grau IV essa técnica está relacionada com maior índice de recorrência e complicações tardias, não devendo ser considerada opção eficiente neste estágio de doença.

ABSTRACT

La enfermedad de Dieulafoy constituye menos del 2 % de las causas de hemorragia digestiva alta. Corresponde a la presencia de un vaso sanguíneo arterial de trayecto tortuoso, que protruye a través de un defecto mucoso localizado, generalmente, proximal en el estómago. Se presenta como una hematemesis masiva, a veces recu-rrente, con inestabilidad hemodinámica. La endoscopia es el método diagnóstico y terapéutico de elección. Si esta fracasa, está indicado practicar una angiografía selectiva que permita identificar el punto sangrante y producir un embolismo. En algunas ocasiones, ninguna de estas dos técnicas consigue detener la hemorragia, en cuyo caso está indicada una cirugía urgente. Se deben practicar resecciones gástricas limitadas (gastrectomías en cuña o tubulares) a la zona sangrante localizada mediante las pruebas anteriores; así, se evitan grandes gastrectomías que implican la práctica de anastomosis por el gran riesgo de dehiscencia que estas últimas cuando hay inestabilidad hemodinámica.Se presenta el caso de un paciente con hemorragia digestiva alta secundaria a enfermedad de Dieulafoy, que precisó intervención quirúrgica urgente por la imposibilidad de resolver el sangrado mediante endoscopia. Se describen el diagnóstico y el tratamiento de la enfermedad de Dieulafoy como causa de hemorragia digestiva alta en el adulto, y se presenta una revisión de la literatura científica


Dieulafoy's disease constitutes less than 2% of the causes of upper gastrointestinal bleeding. It corresponds to the presence of a tortuous arterial blood vessel which protrudes through a localized mucosal defect, usually proximal in the stomach. It presents as a massive hematemesis, sometimes recurrent, with hemodynamic instability.Endoscopy is the diagnostic and therapeutic method of choice. If this fails, it is indicated to perform a selective angiography to identify the bleeding point and embolize it. In some cases, none of these two techniques manages to stop the bleeding, in which case urgent surgery is indicated. Limited gastric resections (wedge or tubular gastrectomies) should be performed to the bleeding area, thus avoiding large gastrectomies that involve anastomosis due to the high leak risk they have in hemodynamically unstable patients.We present the case of a patient with upper gastrointestinal bleeding secondary to Dieulafoy's disease, who required urgent surgical intervention due to the impossibility of resolving the bleeding endoscopically. The diagnosis and treatment of Dieulafoy's disease as a cause of upper gastrointestinal bleeding in adults are described and a review of the scientific literature is presented

ABSTRACT

RESUMEN Se denomina duplicación intestinal a un grupo de malformaciones congénitas de la vía digestiva, de estructuras diverticulares, quísticas o tubulares, que presentan paredes de músculo liso como las del intestino y un revestimiento mucoso de tipo gastrointestinal. Se localiza en cualquier segmento del tubo digestivo, desde la boca hasta el ano. La zona más afectada es el íleon y constituye la causa más frecuente de masa abdominal en el periodo neonatal. El diagnóstico puede ser prenatal a través, de ecografía o resonancia. En el periodo posnatal es la clínica la que establece los indicios para realizar exámenes complementarios, que pueden ir desde ecografía hasta estudios con Tecnecio 99. En la porción duodenal esta enfermedad representa el 5 por ciento de todas las duplicaciones intestinales. La descripción de casos en la primera porción es excepcional, por lo que la consideramos para tener en cuenta como diagnóstico diferencial en las enfermedades tumorales neonatales de origen abdominal(AU)


ABSTRACT Intestinal duplication defines a group of congenital malformations of the digestive tract, of diverticular, cystic or tubular structures, which have smooth muscle walls such as those of the intestine and a gastrointestinal-type mucous lining. It is located in any segment of the digestive tract, from the mouth to the anus. The most affected area is the ileum, while the condition constitutes the most frequent cause of abdominal mass in the neonatal period. The diagnosis can be prenatal through either ultrasound or resonance. In the postnatal period, the clinical indications establish, based on the signs, whether complementary tests are required, which can range from ultrasound to studies with technetium-99. In the duodenal portion, this disease represents 5 percent of all intestinal duplications. The description of cases in the first portion is exceptional, which is the reason why we consider it as a differential diagnosis in neonatal tumor diseases of abdominal origin(AU)

ABSTRACT

Motiva esta presentación el hecho que desde el Relato "Opciones terapéuticas del Cáncer de Recto Inferior" en el año 2008 han pasado 10 años y por supuesto aparecieron algunos progresos y cambios. Se conoce gran heterogeneidad genética debido que puede desarrollarse por diferentes vías. Nuevos fármacos han aparecido para lograr terapia eficiente. La clasificación clínica TNM fue actualizada en el año 2018. Los métodos de diagnóstico siguen teniendo vigencia. La resección local endoanal se presenta como una conducta factible con resultados favorables debido al progreso instrumental. Combinado con R/T y Q mostró excelentes resultados ("Watch and Wait"). La escisión total de mesorecto sigue ocupando un lugar importante. En la amputación abdomino perineal debemos incluir la resección de ambos músculos elevadores del ano. La cirugía laparoscópica ocupa cada vez más lugar siendo tan segura como la convencional. Se adjuntan los algoritmos terapéuticos. Continuarán las investigaciones para mejorar los resultados. (AU)


The aim of this presentation is to update the one written in 2008 "Low rectal cancer therapeutic options" since some progress and changes have appeared after ten years. Great genetic heterogeneity is known because it can develop in different pathways. New drugs have appeared to achieve efficient therapy. The TNM clinical classification was updated in 2018. The diagnosis methods are still in effect. Endoanal local resection is presented as feasible behavior with favorable results due to instrumental progress. Combined with R/T and Ch showed excellent results (Watch and Wait). The total mesorectal continues to occupy an important place. The resection of both elevator muscles of anus must be included in the abdominoperineal amputation. Laparoscopic surgery is increasingly in place, being as safe as the conventional. Therapeutic algorithms are attached. Research will continue to improve results. (AU)

ABSTRACT

Resumen La cirugía ha pasado de ser una ciencia rudimentaria caracterizada por el padecimiento de insufribles dolores por falta de anestésicos, de realizarse en lugares poco acondicionados y de utilizarse instrumental poco ortodoxo con consecuencias nefastas para el desenlace de los procedimientos debido principalmente a las infecciones, a ser un campo desarrollado donde la tecnología juega un rol trascendental para el objetivo final que es el bienestar del paciente. En las últimas décadas, la cirugía ha pasado del acceso abierto al laparoscópico, cirugía por orificios naturales (NOTES), cirugía laparoscópica de puerto único, hasta la cirugía robótica. Es un hecho que estamos en un momento de la historia de la humanidad en el cual el desarrollo de las tecnologías a cambiado nuestra vida cotidiana, así como también el de nuestra practica quirúrgica diaria y no podemos ser ajenos a esta. El propósito de esta revisión es mostrar la situación actual de la cirugía robótica gastrointestinal y sus perspectivas a futuro. Para esto se realizó una búsqueda en la base de datos medline con las palabras claves "review robotic surgery, robotic digestive surgery, robotic bariatric surgery, robotic esophagectomy, robotic gastrectomy, robotic hepatectomy, robotic pancreatectomy, robotic hernia repair". Además una búsqueda de datos en la web sobre "intutive investorpresentation, future of robotic surgery, digital surgery, new robotic system in surgery, trends in robotic surgery".


It is a fact that we are at a moment in the history of humanity in which the development of technologies has changed our daily lives, as well as that of our daily surgical practice. The fast evolution in technology has allowed surgery to evolve from a rudimentary science characterized by painful, highly invasive procedures, to a rapidly developing and precise field with ever improving patient outcomes. In recent decades, gastrointestinal surgery has gone from open access to laparoscopy, natural orifice transluminal endoscopic surgery (NOTES), single-port laparoscopic surgery, and more recently, robotic assisted surgery. The purpose of this review is to show the current situation of robotic gastrointestinal surgery and its future prospects. A literature review was conducted in the Medline database with the keywords "revision of robotic surgery, robotic digestive surgery, bariatric robotic surgery, robotic esophagectomy, robotic gastrectomy, robotic hepatectomy, robotic pancreatectomy, robotic hernia repair". In addition, online search engine data was conducted using the following key words "intutive investor presentation, future of robotic surgery, digital surgery, new robotic system in surgery, trends in robotic surgery"
