Tratamiento de la apendicitis aguda / Acute Appendicitis Management

RESUMEN El objetivo del trabajo es profundizar en los diferentes aspectos cognoscitivos sobre las nuevas evidencias concernientes al tratamiento de la apendicitis aguda y comparar los resultados obtenidos con las diferentes técnicas quirúrgicas empleadas actualmente y el tratamiento conservador. Se realizó una revisión bibliográfica y se seleccionaron artículos en las fuentes electrónicas: Web of Science, Scielo, Elsevier, PubMed, Medline y Google, publicadas en la presente centuria en idiomas español e inglés. La apendicetomía mediante laparotomía ha sido siempre la regla de oro para el tratamiento de la apendicitis aguda. En 1982, se introdujo el acceso laparoscópico que ha demostrado ser tan seguro y eficiente como el convencional. En 2004, la cirugía endoscópica a través de orificios naturales; en 2007 por un solo puerto y en 2015 mediante endoscopia retrógrada. La evolución del cuadro clínico es variable por lo que se han propuesto estrategias como la cirugía ambulatoria, el tratamiento conservador seguido o no de cirugía de intervalo, a fin de evitar intervenciones innecesarias con morbilidad y mortalidad similares a las realizadas con urgencia. La apendicetomía mediante laparotomía o laparoscopia aun es la regla de oro del tratamiento de la apendicitis aguda, aunque se impone el acceso laparoscópico, han surgido nuevas técnicas invasivas y la cirugía ambulatoria. La antibioticoterapia es esencial y como tratamiento único tiene como objetivo disminuir los costos y la morbilidad asociada a la cirugía; por tanto, actualmente el tratamiento adecuado de esta enfermedad es controversial y dependerá de los protocolos de actuación establecidos, el estado del paciente y los recursos disponibles(AU)

ABSTRACT The objective of this work is to study in depth the different cognitive aspects about the new evidences concerning the treatment of acute appendicitis and to compare the results obtained with the different surgical techniques currently used and the conservative treatment. A bibliographic review was carried out and articles were chosen from the electronic sources Web of Science, Scielo, Elsevier, PubMed, Medline, and Google, published in this century in Spanish and in English. Appendectomy by laparotomy has always been the gold standard for the treatment of acute appendicitis. In 1982, laparoscopic access was introduced, which has proven safe and efficient as conventional access. In 2004, endoscopic surgery through natural orifices was used; in 2007, it was performed by a single port, and in 2015, through retrograde endoscopy. The evolution of the clinical picture is variable so strategies have been proposed such as ambulatory surgery, conservative treatment followed or not by interval surgery, in order to avoid unnecessary interventions with morbidity and mortality similar to those performed with urgency. Appendectomy by laparotomy or laparoscopy is still the golden standard of the treatment of acute appendicitis, although laparoscopic access is required, new invasive techniques and outpatient surgery have emerged. Antibiotic therapy is essential and, as a single treatment, aims to reduce costs and morbidity associated with surgery; therefore, the adequate treatment of this disease is currently controversial and will depend on the established protocols of action, patient condition, and the available resources(AU)

Retroperitoneal abscess after transanal minimally invasive surgery: case report and review of literature / Abscesso retroperitoneal após cirurgia de ressecção transanal minimamente invasiva: relato de caso clínico e revisão a literatura médica

ABSTRACT Abscesses are a rare complication of transanal minimally invasive surgery and transanal endoscopic micro surgery. Reported cases have been in the rectal and pre-sacral areas and have been managed with either antibiotics alone or in conjunction with laparotomy and diverting colostomy. We report a case of a large retroperitoneal abscess following a Transanal minimally invasive surgery full thickness rectal polyp excision. The patient was successfully managed conservatively with antibiotics and a percutaneous drain. Retroperitoneal infection should be included in a differential diagnosis following a Transanal minimally invasive surgery procedure as the presentation can be insidious and timely intervention is needed to prevent further morbidity.

RESUMO Os abscessos são uma complicação rara da cirurgia de ressecção transanal minimamente invasiva (TAMIS) e da micro cirurgia endoscópica transanal (TEMS). Os casos notificados foram nas áreas rectal e pré-sacral e foram administrados com antibióticos isoladamente ou em conjunto com laparotomia e desvio de colostomia. Relatamos um caso de grande abscesso retroperitoneal após uma excisão de pólipo retal de espessura total TAMIS. O paciente foi tratado com sucesso com a administração de antibióticos e drenagem percutânea. Para prevenir mais morbidade é necessária incluir a infecção retroperitoneal no diagnostico diferencial após um procedimento TAMIS onde a apresentação pode ser insidiosa e a intervenção atempada.
