ABSTRACT

Horseshoe kidney (HSK) has a prevalence of 1 in every 500 individuals. The management of patients with HSK is usually conservative, except in the presence of symptoms such as obstruction, stones, glomerulopathies, and tumors. In the following case report, we describe how a bilateral en-block transmesenteric laparoscopic nephrectomy in supine position was performed. A 5-year-old boy, with proximal hypospadias and early onset of chronic kidney disease due to focal segmental glomerulosclerosis on biopsy, underwent a genetic molecular evaluation that confirmed a pathogenic mutation at the WT-1 gene. Due to the increased risk of developing Wilms tumor, he underwent a bilateral transmesenteric nephrectomy. In a five-minute video, we describe how we performed an en-block transperitoneal and transmesenteric laparoscopic nephrectomy with special attention to patient positioning, including the feasibility of performing the dissection of the left renal hilum and isthmus with the patient in supine with no need for repositioning, and then moving to the dissection of the right renal hilum and completion of the procedure. The case herein reported enables us to describe the technical key-points to perform a bilateral en-block laparoscopic nephrectomy with shorter operative time and reduction of blood loss by preserving the entire specimen, without the need for an isthmus transection.

ABSTRACT

ABSTRACT Introduction: Nephrometric scores play an interesting role in nephron sparring surgery (NSS) planning. The aim of this study is to evaluate if R.E.N.A.L. score (RS) is capable to predict the occurrence of adverse events in laparoscopic NSS. Materials and Methods: We prospectively studied 150 laparoscopic NSS between 2015 and 2018 to evaluate the relationship between RS and incidence of adverse events. Clavien 3 or superior complications, warm ischemia time (WIT) over 30 minutes, tumor violation, positive surgical margins (PSM) and necessity of amplification of renal parenchyma during the resection of the masses to obtain free margins were considered as adverse events. We compared each item of the RS isolated and divided the patients between low risk and high risk. Results: Adverse results occurred in 48 cases (32%). Amplification of the margin of resection was observed in 28 cases (19%). WIT exceeded 30 minutes in 9 cases (6.1%), complications Clavien 3 or superior occurred in 13 cases (9%) and PSM were detected en 6 cases (4%). Comparing the patients with adverse outcomes and each item of the RS we did not find any statistical difference, but when divided into high risk and low risk, we found that patients in the high risk group had a higher tendency to present ad-verse results - 25.84% vs. 44.26% (p=0.03). Conclusions: RS system is a good way to predict adverse outcomes in NSS, especially in cases over 7. Further studies should focus on robotic approach and patient's characteristics other than the masses' aspects.

ABSTRACT

Introducción. Los linfangiomas son anormalidades benignas del sistema linfático, que corresponden a dilataciones quísticas de estos vasos y se localizan especialmente en el cuello. Solo el 10 % de todas estas malformaciones se encuentran en el abdomen y presentan síntomas variables de acuerdo al tamaño y su ubicación especifica, siendo el dolor abdominal el principal síntoma. Métodos. Se presentan cinco pacientes pediátricos con malformaciones linfáticas abdominales. Se describen su cuadro clínico, localización, tratamiento y la experiencia en el manejo de dicha patología en un hospital de referencia. Resultados. Los métodos más apropiados para hacer una aproximación diagnóstica son la ecografía, la tomografía computarizada y la resonancia nuclear magnética. Dentro de las opciones descritas para el tratamiento están la farmacológica, la escleroterapia y la resección quirúrgica, tanto por vía abierta como por laparoscopia. Conclusión. Existe una variedad de métodos para realizar la resección de los linfangiomas abdominales, pero la cirugía sigue siendo la más efectiva, especialmente cuando se cuenta con la laparoscopia como una herramienta terapéutica.


Introduction. Lymphangiomas are benign abnormalities of the lymphatic system, which correspond to cystic dilations of these vessels and are located especially in the neck. Only 10% of all these malformations are found in the abdomen and present variable symptoms according to size and their specific location, with abdominal pain being the main symptom. Methods. Five pediatric patients with abdominal lymphatic malformations are presented. Their clinical presentation, location, treatment and experience in the management of this pathology in a referral hospital are described. Results. The most appropriate methods to make a diagnostic approach are ultrasound, computed tomography and magnetic resonance imaging. Among the options described for treatment are pharmacological, sclerotherapy and surgical resection, both open and laparoscopic. Conclusion. There are a variety of methods for resecting abdominal lymphangiomas, but surgery remains the most effective, especially when laparoscopy is used as a therapeutic tool.

ABSTRACT

ABSTRACT Objective: to develop a training program in minimally invasive surgery, based on simulation and with an emphasis on the acquisition of laparoscopic competences. Methods: this was a prospective, observational study carried out at a university hospital in Belo Horizonte, Brazil, between April 2020 and January 2021. We recruited residents of surgical specialties for structured, progressive training according to instructional principles to promote learning, such as motivation, activation, demonstration, application, and integration. We filmed the skill tests at the program's beginning, middle, and end, which were then anonymously evaluated by a surgical education expert. Individual performances were scored using the global assessment tools "GOALS" and "specific checklist for suture". At the end, all participants received individual feedback and completed a questionnaire to assess the impact of training on the Kirkpatrick model. Results: 43 residents completed the program. The evolution of performances was evident and grew between tests. The average achievements were 29% in the initial test, 43% in the intermediate test, and 88% in the final test, with significant differences between all mean scores, with H=97.59, GL=2, p<0.0001. The program evaluation and learning perceptions were excellent, but only 10.7% of residents felt fully capable of performing unsupervised, low-complexity laparoscopic surgery at the end of training. Conclusions: the training program developed in this study proved to be feasible and promising as a strategy for teaching laparoscopic surgery.


RESUMO Objetivo: desenvolver programa de treinamento em cirurgia minimamente invasiva, baseado em simulação e com ênfase na aquisição de competências laparoscópicas. Métodos: trata-se de estudo prospectivo observacional que foi realizado em hospital universitário de Belo Horizonte, Brasil, entre abril de 2020 e janeiro de 2021. Foram recrutados residentes de clínicas cirúrgicas para treinamento progressivo estruturado de acordo com princípios instrucionais de promoção da aprendizagem, como: motivação, ativação, demonstração, aplicação e integração. Testes de habilidades foram filmados no início, meio e final do programa, e, então, avaliados em anonimato por perito em educação cirúrgica. As performances individuais foram pontuadas por meio das ferramentas de avaliação global "GOALS" e "checklist específico de sutura". Ao final, todos participantes receberam feedbacks individuais e preencheram questionário destinado a avaliar o impacto do treinamento, baseado no modelo de Kirkpatrick. Resultados: 43 residentes concluíram o treinamento. A evolução das performances foi crescente e evidente entre os testes. Os aproveitamentos médios foram: 29% no teste inicial; 43% no teste intermediário; e 88% no teste final, com diferenças significativas entre todas as médias de pontuação, sendo H=97,59; GL=2; p<0,0001. A avaliação do programa e percepções de aprendizagem foram excelentes, mas apenas 10,7% dos residentes sentiram-se totalmente capazes a realizar cirurgia laparoscópica de baixa complexidade sem supervisão ao final do treinamento. Conclusões: o programa de treinamento desenvolvido nesse estudo mostrou-se factível e promissor como estratégia de ensino da cirurgia laparoscópica.

ABSTRACT

ABSTRACT Introduction: Laparoscopic appendectomy does not have a single protocol on its technical systematization, access routes, and use of energy and staplers. The cost of disposable materials can prevent its widespread use. Alternatives to decrease cost can help disseminate the laparoscopic access to appendectomy. Objective: to introduce a low-cost laparoscopic appendectomy method with good aesthetic results through the location of incisions; to show its viability through its application in 1,552 cases of laparoscopic appendectomy operated between 2000 and 2019 with three portals and very low-cost regarding materials used. Methods: we applied three punctures - an umbilical one for the camera (5 or 10mm in diameter), a 10mm puncture in the right iliac fossa, and one 5mm puncture in the left iliac fossa. The materials used were permanent use trocars, grasping forceps, hook, scissors, and needle holder, without the need for any disposable device. Results: 1.552 patients were operated between 2000 and 2019, 56.2% being female, mean age 32.66 years (9-93), average hospital stay of 1.74 days (1-10), and median of 1.2 days. Conclusion: the technique we describe uses three metallic trocars and four permanent instruments, in addition to a single cotton suture. It is, therefore, a very low-cost laparoscopic procedure. Its application has shown good results and low morbidity, which may become the preferred indication for laparoscopic surgery in the treatment of acute appendicitis.


RESUMO Introdução: a apendicectomia videolaparoscópica não tem protocolo único sobre sistematização técnica, vias de acesso, uso de energia e grampeadores. O custo de materiais descartáveis pode inviabilizar o emprego mais generalizado. Alternativas para diminuir o custo podem ajudar a disseminar o acesso laparoscópico para a realização de apendicectomia. Objetivo: introduzir um método para realizar a apendicectomia videolaparoscópica de baixo custo e visando bom resultado estético por meio da localização das incisões; mostrar a viabilidade por meio de aplicação em 1.552 casos de apendicectomia videolaparoscópica operados entre 2000 e 2019 com três portais, de muito baixo custo em insumos utilizados. Métodos: três punções - uma punção umbilical para introdução da câmera (de 5 ou 10mm de diâmetro), uma punção de 10mm em fossa ilíaca direita e uma punção em fossa ilíaca esquerda de 5mm. Os materiais utilizados - trocartes, pinças de apreensão, gancho, tesoura e porta-agulhas são de uso permanente, sem necessidade de qualquer material descartável. Resultados: foram operados 1.552 pacientes entre 2000 e 2019, sendo 56,25% do sexo feminino, média de idade de 32,66 anos (9 a 93 anos), tempo médio de internação de 1,74 dias (1 a 10 dias) e mediana de 1,2 dias. Conclusão: a técnica que descrevemos utiliza três trocartes metálicos e quatro instrumentos permanentes, além de um único fio de algodão. Trata-se, portanto, de procedimento laparoscópico de muito baixo custo. A aplicação demonstrou bons resultados e baixa morbidade, podendo tornar-se rotina a indicação preferencial da vídeocirurgia no tratamento da apendicite aguda.

ABSTRACT

Resumen Introducción: La fístula colovesical es la unión entre la vejiga y el intestino grueso, se presenta en el 2% de los pacientes con enfermedad diverticular del colon, genera síntomas como neumaturia y fecaluria, asociados a infecciones urinarias recurrentes. Los pacientes se diagnostican mediante estudios imagenológicos y su tratamiento generalmente es quirúrgico. Objetivo: Reportar el caso de tratamiento laparoscópico de paciente con fístula colovesical secundaria a diverticulitis complicada. Caso clínico: Se presenta el caso de un paciente masculino de 69 años, con antecedente de enfermedad diverticular, cursando con infección de vías urinarias recurrentes, fecaluria y neumaturia. La cistoscopia no mostró trayecto fistuloso y la tomografía abdominopélvica mostró hallazgos inflamatorios y fístula colovesical asociada a diverticulitis complicada. Durante procedimiento laparoscópico se encuentra absceso pericólico sin evidencia del trayecto fistuloso, se realizó drenaje, sutura del colon e interposición del epiplón, sin resección intestinal. Paciente con adecuada evolución postoperatoria con egreso al sexto día. El objetivo del tratamiento quirúrgico se centra en el control de complicaciones generadas por los divertículos, en este caso, la fístula colovesical. Conclusiones: El procedimiento laparoscópico es de mínima invasión, no presenta la morbilidad que implica una resección de colon o una colostomía y se asocia con una recuperación funcional más rápida.


Abstract Introduction: The colovesical fistula is a junction between the urinary bladder and the large intestine. It occurs in 2% of patients with diverticular disease of the colon and generates symptoms such as pneumaturia and fecaluria associated with recurrent urinary tract infections. The patients are diagnosed by imaging studies and their treatment is usually surgical. Objective: To report the laparoscopic treatment administered to a patient that presented a case of colovesical fistula secondary to severe diverticulitis. Case report: The case of a 69-year-old male patient with a medical record of diverticular disease, who presented recurrent urinary tract infection, fecaluria, and pneumaturia is presented. The cystoscopy procedure showed no signs of anal fistula, and the abdominopelvic tomography showed signals of inflammations and colovesical fistula associated with complicated diverticulitis. During the laparoscopic procedure, a pericolic abscess was found without evidence of anal fistula. Drainage and suture of the colon and omentum interposition were performed without presenting intestinal resection. The patient had an adequate postoperative recovery and was discharged on the sixth day. The aim of this surgical treatment is focused on the control of medical complications caused by diverticulitis, in this case, colovesical fistula. Conclusions: This procedure is minimally invasive, and it is associated with a faster functional recovery since it does not present the morbidity of a colon resection or colostomy.

ABSTRACT

Introducción. La hernia de Garengeot se caracteriza por contener el apéndice cecal dentro del saco femoral, y forma parte de una variedad de hernias que reciben el epónimo de acuerdo con su localización anatómica. Entre ellas se encuentra la hernia de Richter, la hernia de Amyand, la hernia de Littré y la hernia de Spiegel. Se presenta una revisión de los abordajes laparoscópicos para estas diversas variantes. Caso clínico. Paciente femenina de 82 años de edad quien consultó al servicio de urgencias por dolor inguinal derecho de ocho días de evolución, asociado a clínica de obstrucción intestinal. Se hizo diagnóstico de hernia inguinal encarcelada y se llevó a cirugía encontrando una hernia de Garengeot. Discusión. Además de los tipos de hernia tradicionalmente conocidos, existen variantes inusuales de hernias de la pared abdominal, que deben ser sospechadas y tenidas en cuenta como diagnóstico diferencial, lo que permitirá realizar su tratamiento de forma oportuna disminuyendo el riesgo de que ocurra una perforación intestinal. Conclusiones. Las variantes de hernia inguinal o de localización inusual, son susceptibles de tratamiento quirúrgico mediante abordajes laparoscópicos con adecuados resultados.


Introduction. Garengeot's hernia is characterized by containing the cecal appendix within the femoral sac, and is part of a variety of hernias that receive their eponymous according to their anatomical location. These include Richter's hernia, Amyand's hernia, Littré's hernia, and Spiegel's hernia. We present a review of the laparoscopic approaches for these variants. Clinical case. An 82-year-old female patient consulted to the emergency department for right groin pain of eight days of evolution, associated with symptoms of intestinal obstruction. With a diagnosis of incarcerated inguinal hernia, she underwent surgery finding a Garengeot ́s hernia. Discussion. In addition to the traditionally known types of hernia, there are unusual variants of hernias of the abdominal wall, which must be suspected and taken into account as a differential diagnosis, which will allow treatment to be carried out in a timely manner, reducing the risk of intestinal perforation. Conclusions. Variants of inguinal hernia or unusual location are susceptible to surgical treatment by laparoscopic approaches with adequate results.

ABSTRACT

Sigmoid volvulus is a frequent cause of intestinal obstruction. Its management has evolved with the use of laparoscopic surgery, achieving an elective sigmoid resection with anastomosis after a flexible endoscopic detorsion. A female patient was admitted to the emergency room with abdominal pain, distention, and constipation. The abdominal computed tomography showed a whirled sigmoid mesentery in addition to dilated sigmoid loops, and coffee bean sign. The patient successfully underwent a flexible endoscopic detorsion and was scheduled for elective sigmoid colectomy with rectal superior artery preservation and primary anastomosis. During the sigmoid resection, the superior rectal artery preservation is related to a better prognostic, with less bleeding, anastomotic leakage, and hospital stay. Currently, there are few reports of the laparoscopic preservation of the superior rectal artery in patients with sigmoid volvulus. (AU)

ABSTRACT

Resumen: Introducción: si bien la esplenectomía laparoscópica en esplenomegalias masivas y supramasivas constituye un desafío técnico, su realización es factible y segura en centros con equipos con experiencia en cirugía laparoscópica. Objetivo: presentar el primer caso de esplenectomía laparoscópica en esplenomegalia masiva realizada en Uruguay. Caso clínico: se trata de una paciente de 70 años portadora de una pancitopenia periférica, esplenomegalia masiva y diagnóstico realizado por punción de médula ósea de neoplasia linfoproliferativa tipo B de bajo grado, a quien se le indicó la esplenectomía con fines diagnósticos y terapéuticos. La paciente se operó en decúbito lateral derecho a 15 grados, los trócares se colocaron bajo visión directa adaptados al tamaño del bazo que se extendía desde el diafragma hasta el estrecho superior de la pelvis. Se realizó la esplenectomía en un tiempo de 220 minutos, extrayéndose la pieza íntegra y sin haberla colocado en bolsa a través de un hemi Pfannenstiel, protegiendo la pared con un retractor de heridas quirúrgicas. No presentó complicaciones, fue dada de alta a las 48 horas. El hemograma realizado a las 24 horas demostró un aumento de las cifras de todas las series celulares y el informe anatomopatológico diagnosticó un linfoma no Hodgkin de zona marginal. Discusión: la esplenectomía laparoscópica en esplenomegalias masivas requiere de un mayor tiempo quirúrgico, aunque las pérdidas sanguíneas y la estadía hospitalaria son menores en comparación a los procedimientos convencionales, presentando una morbilidad similar. En la experiencia inicial de los equipos quirúrgicos se reporta un porcentaje de conversiones y reingresos cercanos al 30%.


Abstract: Introduction: despite the fact that laparoscopic splenectomy for massive and supramassive splenomegaly constitutes a technical challenge, it is a feasible and safe procedure in the context of institutions with experienced teams in laparoscopic surgery. Objective: to present the first case of laparoscopic splenectomy for massive splenomegaly in Uruguay. Clinical case: the study presents the case of a 70-year-old patient carrier of peripheral pancytopenia, massive splenomegaly and a diagnosis of type B lymphoproliferative neoplasm based on bone marrow aspiration and biopsy, who underwent diagnostic and therapeutic splenectomy. The patient was operated in supine position with a 15-degree tilt, the trocars were placed under direct view, adapted to the size of the spleen which went from the diaphragm until the superior pelvic outlet. Splenectomy was performed in 220 minutes, the entire piece was removed through a hemi Pfannenstiel incision, without placing it in a bag, the wall being protected with a surgical wound retractor. There were no complications and the patient was discharged from hospital 48 hours. The blood count performed after 24 hours evidenced increase in all cell series and the pathology report confirmed diagnosis of marginal zone non- Hodgkin lymphoma. Discussion: laparoscoppic splenectomy in massive splenomegaly requires of a greater surgical time, although blood loss and hospital star are lower when compared to conventional procedures and evidence similar morbility. The initial experience of surgical teams reports 30% of conversions and readmissions.


Resumo: Introdução: embora a esplenectomia laparoscópica em esplenomegalias massivas e supremassivas seja um desafio técnico, sua realização é viável e segura em centros com equipes com experiência em cirurgia laparoscópica. Objetivo: apresentar o primeiro caso de esplenectomia laparoscópica em esplenomegalia maciça realizada no Uruguai. Caso clínico: paciente de 70 anos com pancitopenia periférica, esplenomegalia maciça e diagnóstico feito por punção de medula óssea de neoplasia linfoproliferativa tipo B de baixo grau, com indicação de esplenectomia para fins diagnósticos e terapêuticos. A paciente foi operada em decúbito lateral direito a 15 graus, os trocartes foram colocados sob visão direta adaptados ao tamanho do baço que se estendia do diafragma ao estreito superior da pelve. A esplenectomia foi realizada em um tempo de 220 minutos, retirando-se toda a peça e sem colocá-la em bolsa por meio de uma hemi Pfannenstiel, protegendo a parede com afastador de ferida operatória. Sem apresentar complicações a paciente teve alta após 48 horas. O hemograma realizado 24 horas depois da cirurgia mostrou um aumento no número de todas as séries de células e o laudo anatomopatológico diagnosticou linfoma não Hodgkin de zona marginal. Discussão: a esplenectomia laparoscópica nas esplenomegalias maciças requer um tempo cirúrgico maior, embora as perdas sanguíneas e a permanência hospitalar sejam menores em comparação aos procedimentos convencionais, apresentando morbidade semelhante. Na experiência inicial das equipes cirúrgicas, é relatado um percentual de conversões e readmissões próximo a 30%.

ABSTRACT

RESUMEN Desde la aparición de un programa de Fast Track en cirugía colónica con resultados alentadores, muchos centros se abocaron a su aplicación y mejoramiento. El uso de estos programas en diferentes órganos trajo aparejados los mismos resultados que en cirugía colónica. Las resecciones hepáticas no quedaron excluidas de su uso. En ellas se logró una importante reducción de los días de estancia hospitalaria y de los costos. Entre los puntos que componen estos programas, una adecuada información al paciente y un compromiso de parte de este, la analgesia multimodal, la fluidoterapia y un inicio temprano de la alimentación parecen ser los más importantes.


ABSTRACT Since the development of fast-track programs in colorectal surgery with promising results, many centers started with these programs, and improved them. These programs were applied to different organs with the same results observed in colorectal surgery. Liver resections were not excluded from enhanced recovery programs, with a significant reduction in length of hospital stay and costs. Adequate patient information and commitment, multimodal analgesia, fluid therapy and early oral intake are the most important items of these programs.

Objetivo: presentar la experiencia y aplicabilidad de hepatectomías videolaparoscópicas. Material y métodos: análisis retrospectivo de pacientes sometidos a una hepatectomía entre agosto de 2010 y diciembre de 2019. Analizamos variables preoperatorias, intraoperatorias y posoperatorias. Para evaluar la aplicabilidad, se dividió la muestra en: Etapa 1: agosto de 2010 a diciembre de 2013; Etapa 2: enero de 2014 a diciembre de 2016, Etapa 3: enero de 2017 a diciembre de 2019. Resultados: de 385 hepatectomías realizadas, 119 fueron videolaparoscópicas: 53 (44%) fueron to talmente laparoscópicas, 64 (54%) mano-asistidas y 2 híbridas. La aplicabilidad global fue 31%. En la etapa 1: 23% , en la 2: 30% y en la 3: 44% (p < 0,05). Fueron patología maligna en la etapa 1: 36%, en la 2: 67% y en la 3: 72% (p < 0,05). Hepatectomías mayores: 13%, 31% y 32% en etapas 1, 2, y 3, respectivamente (p < 0,05). El índice de conversión fue 12%, 0% y 11%, respectivamente (p NS). Se utilizó clampeo pedicular en: 6%, 5% y 45%; (p < 0,05). Las complicaciones en la etapa 1 fueron 30%, en la 2: 28% y en la 3: 17%, siendo complicaciones Dindo-Clavien III o más, el 6%, 13% y 5%, respectivamente, p NS. Conclusiones: Aa pesar de su complejidad, las hepatectomías videolaparoscópicas son técnicamente reproducibles. Adquiriendo experiencia, podemos aumentar la aplicabilidad, a favor de la patología oncológica y complejidad, sin comprometer la seguridad del paciente.


ABSTRACT Background: Despite laparoscopic liver resection has significantly evolved, most hepatectomies are performed by the conventional approach. Objective: The aim of this study is to present the initial experience and applicability of laparoscopic liver resections. Material and methods: We conducted a retrospective analysis of patients undergoing liver resection between August 2010 and December 2019. Perioperative, intraoperative and postoperative variables were analyzed. To evaluate applicability, the sample was divided into 3 stages: stage 1, from August 2010 to December 2013; stage 2, from January 2014 to December 2016; and stage 3, from January 2017 to December 2019. Results: Of 385 liver resections performed, 119 were laparoscopic procedures: 53 (44%) were pure laparoscopic procedures, 64 (54%) were hand-assisted (64 patients) and 2 corresponded to hybrid procedures. Global applicability was 31%. In stage 1 1: 23%, in 2: 30% and in 3: 44% (p < 0.05). Malignant lesions: stage 1: 36%, stage 2: 67% and stage 3: 72% (p < 0.05). Major liver resections: 13%, 31% and 32% in stages 1, 2, and 3, respectively (p < 0.05). Conversion rate was 12%, 0% and 11%, respectively (p NS). Hepatic pedicle clamping was used in 6%, 5% and 45%; (p < 0.05). Complications in stage 1 were 30%, in stage 2: 28% and in stage 3: 17%, and Clavien-Dindo complications grade 3 or greater were 6%, 13% and 5%, respectively, p NS. Conclusions: Laparoscopic liver resections are complex procedures but technically reproducible. Applicability increases with the acquisition of experience, not only in malignant lesions but also in complex lesions ensuring safety for the patient.

ABSTRACT

Introducción. La apendicectomía por laparoscopia se considera el patrón de oro en el tratamiento de la apendicitis aguda. Sin embargo, su disponibilidad es limitada en nuestro sistema de salud, principalmente por los costos asociados. El objetivo de este estudio fue evaluar la relación entre el uso de los diferentes tipos de energía y los métodos de ligadura de la base apendicular, con las complicaciones postoperatorias, al igual que describir los costos asociados. Métodos. Estudio observacional analítico de una cohorte retrospectiva de pacientes mayores de 15 años a quienes se les realizó apendicectomía por laparoscopia, en un hospital universitario entre los años 2014 y 2018. Se utilizaron modelos de regresión logística y lineal para evaluar la relación entre métodos de ligadura del meso y base apendicular, desenlaces operatorios y costos. Resultados. Se realizaron 2074 apendicectomías por laparoscopia, 58,2 % (n=1207) en mujeres, la edad mediana fue de 32 años. En el 71,5 % (n=1483) la apendicitis aguda no fue complicada. La energía monopolar para la liga-dura del meso apendicular fue la utilizada más frecuentemente en 57,2 % (n=1187) y el Hemolok® el más utilizado para la ligadura de la base apendicular en el 84,8 % (n=1759) de los pacientes. No se observaron diferencias estadísticamente significativas en la tasa de infección del sitio operatorio, reintervención o íleo. El uso de energía simple redujo los costos del procedimiento de manera significativa durante el período evaluado. Discusión. El uso de energía monopolar demostró ser una técnica segura, reproducible y de menor costo en comparación con el uso de energía bipolar, independientemente de la fase de la apendicitis aguda. Lo anterior ha permitido que se realicen más apendicectomías por laparoscopia y que los médicos residentes de cirugía general puedan realizar procedimientos laparoscópicos de forma más temprana


Introduction. Laparoscopic appendectomy is considered the gold standard in the treatment of acute appendicitis. However, its availability is limited in our health system mainly due to the associated costs. The objective of this study is to evaluate the relationship between the use of different types of energy and the methods of ligation of the appendicular base with postoperative complications, as well as to describe the associated costs. Methods. Retrospective observational study of a cohort of patients older than 15 years old who underwent laparoscopic appendectomy in a university hospital between 2014 and 2018. Logistic and linear regression models were used to evaluate the relationship between methods of ligation of the meso and appendicular base, operative outcomes and costs. Results: 2074 laparoscopic appendectomies were performed. Of those, 58.2% (n=1207) were women, median age was 32 years. In 71.5% (n=1483), acute appendicitis was uncomplicated. Monopolar energy for ligation was the most frequently used for ligation of the appendicular meso in 57.2% (n=1187) and Hem-o-lok® the most used for ligation of the appendicular base in 84.8% (n=1759) of the patients. There were no statistically significant differences in the rate of surgical site infection, reoperation, or ileus. The use of simple energy reduced the costs of the procedure significantly during the study period. Discussion. The use of monopolar energy proved to be a safe, reproducible and a lower cost technique compared to the use of bipolar energy, regardless of the phase of acute appendicitis. This has allowed more laparoscopic appendectomies to be performed and the general surgery residents to perform laparoscopic procedures earlier

ABSTRACT

Introducción. El pilar fundamental del tratamiento del cáncer colorrectal es la cirugía, situación que expone a los pacientes a la posible presentación de complicaciones, morbimortalidad, pobre calidad de vida, recurrencia tumoral o la muerte. El objetivo de este estudio fue determinar las variables clínicas y quirúrgicas que inciden en el riesgo de la aparición de complicaciones en los pacientes con cáncer colorrectal llevados a cirugía electiva entre los años 2016 y 2019. Métodos. Estudio observacional, descriptivo, transversal y retrospectivo. Se incluyeron pacientes mayores de 18 años con cáncer colorrectal sometidos a cirugía electiva. Se realizó un análisis multivariado para determinar los factores que se relacionan con las complicaciones postquirúrgicas. Resultados. Se incluyeron 298 pacientes, 68 % mayores de 60 años, 52,3 % mujeres, 74,2 % presentaban comorbilidades y 48,3 % fueron diagnosticados en estadio III. El 48,3 % presentó complicaciones postoperatorias. De ellos, el 68,1 % no tenía tamización nutricional y el 61,8 % no tenía preparación del colon; un 55 % fueron cirugías del recto, 69,1 % de las cirugías fueron por vía laparoscópica y 71,8 % presentaron sangrado inferior a 500 ml. La mayoría de las complicaciones fueron clasificadas como Clavien-Dindo I-III. Discusión. Las características de los pacientes fueron similares a los presentados en otros estudios, aunque hubo mayor incidencia de íleo postoperatorio. El análisis multivariado mostró una mayor probabilidad de presentar una complicación en pacientes con diabetes mellitus, hipertensión arterial, falta de tamización nutricional o preparación de colon, cirugía de recto y el sangrado mayor a 500 ml


Introduction. The fundamental pillar of colorectal cancer treatment is surgery, a situation that exposes patients to the possible presentation of complications, morbidity and mortality, poor quality of life, tumor recurrence or death. The objective of this study was to determine the clinical and surgical variables that affect the risk of the appearance of complications in colorectal cancer patients taken to elective surgery between 2016 and 2019.Methods. Observational, descriptive, cross-sectional and retrospective study. Patients over the age of 18 with colorectal cancer undergoing elective surgery were included. A multivariate analysis was performed to determine the factors related to postsurgical complications. Results. We included 298 patients, 68% over 60 years of age, 52.3% women, 74.2% had comorbidities and 48.3% were diagnosed in stage III. 48.3% presented postoperative complications; of these, 68.1% had no nutritional screening, and 61.8% had no colon preparation; 55% were rectal cancer surgeries, 69.1% underwent laparoscopic surgeries, and 71.8% had bleeding less than 500 ml. Most complications were classified as Clavien Dindo I-III. Discussion. The characteristic of the patients was similar to those presented in other studies, even though we had more incidence of postoperative ileus. The multivariate analysis showed a higher probability of complications in patients with: diabetes, hypertension, lack of nutritional screening, bleeding over 500cc, lack of colon mechanical preparation and rectal cancer surgery.Patient characteristics were similar to those presented in other studies, although there was a higher incidence of postoperative ileus. The multivariate analysis showed a greater probability of presenting a complication in patients with diabetes mellitus, arterial hypertension, lack of nutritional screening, colon preparation, rectal cancer surgery, and bleeding greater than 500 ml

ABSTRACT

Se presenta el caso de una paciente de 30 años de edad, sometida a un procedimiento de manga gástrica por laparoscopia en marzo de 2014, quien presenta, al tercer y cuarto años del procedimiento inicial, dos episodios de hemoptisis masiva, con falla en la segunda terapia de embolización, por lo que requirió una lobectomía pulmonar inferior izquierda. Al segundo día de este postoperatorio presenta salida de material de nutrición por las sondas de tórax, estableciéndose el diagnóstico de fistula gastropleural. Debido a falla con el manejo conservador, fue sometida a una resección quirúrgica de la fístula por vía laparoscópica, con gastrectomía proximal y reconstrucción en Y de Roux. A propósito de nuestra experiencia con esta paciente, se discuten en este artículo las estrategias de manejo para una fístula gastropleural, propuestas en la literatura a la fecha


This is a clinical case of a 30-year-old patient, who underwent a laparoscopic gastric sleeve procedure in March 2014, who presented, at the third and fourth years of the initial procedure, two episodes of massive hemoptysis, with failure in the second embolization therapy, requiring a lower left pulmonary lobectomy. On the second day of this postoperative period, the nutrition material came out through the chest tubes, establishing the diagnosis of gastropleural fistula. Due to failure of conservative management, she underwent laparoscopic surgical resection of the fistula, with proximal gastrectomy and Roux-en-Y reconstruction. Regarding our experience with this patient, this article discusses the management strategies for a gastropleural fistula, proposed in the literature to date

ABSTRACT

Abstract Zinner's syndrome (ZS) is a rare congenital malformation of the seminal vesicles and ipsilateral upper urinary tract which is characterized by the triad of ipsilateral ejaculatory duct obstruction, semi nal vesicle cysts, and renal agenesis. We report an 18-year-old male who presented intermittent gross hematuria and hematospermia and ejaculation volume diminution. ZS was diagnosed with magnetic resonance imaging (MRI) of the prostate, among other complementary studies requested. We performed a minimally laparoscopic resection of the left seminal vesicle. The postoperative was uneventful symptoms resolved, and 3 months later semen analysis showed increase in ejaculation volume. Currently, the minimally invasive approach is feasible and effective for the treatment of the seminal vesicle cysts excision in the ZS. We presented a symptomatic patient treated by a laparoscopic approach with successful middle follow-up results.


Resumen El síndrome de Zinner (ZS) es una malformación congénita rara de las vesículas seminales y del tracto urinario superior ipsolateral que se caracteriza por la tríada de obstrucción del conducto eyaculatorio ipsolateral, quistes de vesículas seminales y agenesia renal. Presentamos el caso de un varón de 18 años que presentó hematuria macroscópica intermitente y hemospermia y disminución del volumen de eyaculación. El diagnóstico de ZS se realizó mediante resonan cia magnética (RM) de próstata, entre otros estudios complementarios solicitados. Realizamos una resección mínimamente laparoscópica de la vesícula seminal izquierda. El postoperatorio se resolvió sin complicaciones y 3 meses después el análisis de semen mostró un aumento en el volumen de eyaculación. Actualmente, el abordaje mínimamente invasivo es factible y efectivo para el tratamiento de la escisión de quistes de vesículas seminales en el ZS. Presentamos un paciente sintomático tratado por vía laparoscópica con seguimiento medio exitoso.

ABSTRACT

Resumen Introducción: El Síndrome de Mirizzi es una complicación infrecuente de la enfermedad litiásica biliar, con una incidencia menor al 1% en países desarrollados, puede desarrollarse en cinco variantes, siendo menos frecuente la variante tipo V. La literatura actual discrepa sobre el manejo de esta condición, afirmando que la cirugía laparoscópica no es segura como procedimiento estándar. Caso Clínico: Se presenta el caso de Síndrome de Mirizzi en un hombre de 80 años, que es remitido al departamento de urgencias por sospecha de sepsis de origen abdominal, con estudio ecográfico de colelitiasis, neumobilia y dilatación de las vías biliares. Se realizó Colangiopancreatografía retrógrada endoscópica con imposibilidad técnica para la movilización y extracción de los cálculos por gran tamaño, recurriéndose a exploración a través de técnica laparoscópica, obteniéndose resultados satisfactorios. Conclusión: Para tratar el Síndrome de Mirizzi, es necesario considerar las características del paciente y la experiencia del cirujano ya que ambos factores influyen directamente en la modalidad del tratamiento, sus complicaciones y tasas de éxito. En el presente caso, la experiencia del autor principal en el manejo de procedimientos mínimamente invasivos y la consideración de reducir el riesgo de complicaciones como infecciones en un paciente frágil, fueron los factores que influyeron para la decisión de intervención laparoscópica.


Abstract Introduction: Mirizzi's syndrome is an infrequent complication of biliary lithiasic disease, with an incidence of less than 1% in developed countries, being even less frequent the type V variant. Current literature disagrees on the management of this condition, stating that laparoscopic surgery is not safe as a standard procedure. Clinical Case: We present the case of Mirizzi's Syndrome in an 80-year-old man, which is referred to the emergency department for suspicion of sepsis of abdominal origin, with ultrasound study of cholelithiasis, pneumoobilia and dilation of the bile ducts. Retrograde endoscopic cholangiopancreatography was performed with technical impossibility for the mobilization and extraction of large-size stones, resorting to exploration through laparoscopic technique, obtaining satisfactory results. Conclusion: It is necessary to emphasize that the type of Mirizzi syndrome, the patient's characteristics and the surgeon's experience directly influence the treatment modality, its complications and/or success rates. In the present case, the experience of the main author in the management of minimally invasive procedures and the consideration of reducing the risk of complications such as infections in a fragile patient, were the factors that influenced the decision for laparoscopic intervention.
