La frecuencia de complicaciones fue superior al 50 %, en su mayoría menores; se encontró asociación con obesidad para la presencia de seroma. La mortalidad fue del 2,3 %. Conclusión.La hernia incisional es un problema de salud pública. Consideramos que la obesidad y el uso de malla pueden ser factores de riesgo asociados con la presentación de complicaciones postoperatorias, así como el aumento de los gastos relacionados con días de hospitalización

Introduction. Hernias management has become a common surgical problem, with an estimated increase in the coming years. The objective of this study was to describe the clinical course, aspects of surgical treatment and factors associated with the presence of complications in patients operated on for incisional hernia. Methods. Descriptive study, in which the characteristics of a cohort of patients taken to surgical correction of incisional hernia at the Hospital Universitario Hernando Moncaleano Perdomo, a high complexity medical center located in Neiva, Colombia, between 2012 and 2019 were analyzed, whose data were collected in Microsoft Excel® software and analyzed in SPSSTM, version 21. Results. One-hundred-thirty-three incisional hernia corrections were performed. The mean age at the intervention was 52 years ±14.6. The most frequent comorbidities were weight disorders, hypertension and diabetes. Only one laparoscopy was performed, the first etiology of the hernia was traumatic (61.7%) and midline (84.2%). The frequency of complications was greater than 50%, mostly minors. An association with obesity was found for the presence of seroma. Mortality was 2.3%. Conclusion. Incisional hernia is a public health problem. We consider that obesity and the use of mesh are a risk factor associated with the presentation of postoperative complications as well as the increase in costs related to days of hospitalization

Infección temprana de la malla quirúrgica en herniorrafia incisional. Incidencia, factores de riesgo y desenlaces en más de 60.000 pacientes / Early infection of the surgical mesh in incisional herniorrhaphy. Incidence, risk factors, and outcomes in more than 60,000 patients

Introducción. La infección de la malla en cirugía de reparación de hernias de pared abdominal es un desenlace pobre, asociado a un incremento en el riesgo de complicaciones. El objetivo del presente estudio fue analizar la incidencia, los factores asociados y desenlaces en pacientes llevados a herniorrafia incisional con malla con posterior diagnóstico de infección temprana. Métodos. Estudio de cohorte retrospectiva. Se utilizaron los datos de egresos hospitalarios de la National Inpatient Sample (NIS) de los Estados Unidos de América para identificar a todos los pacientes adultos llevados a herniorrafia incisional durante los años 2010 a 2015. Se utilizaron modelos de regresión logística bivariada y multivariada para evaluar los factores de riesgo en infección temprana de la malla, y finalmente, modelos de regresión logística y lineal, según el tipo de variable dependiente, de tipo stepwise forward para evaluar la asociación entre el diagnóstico de infección de malla y los desenlaces adversos. Resultados. En total se incluyeron 63.925 pacientes. La incidencia de infección temprana de la malla fue de 0,59 %, encontrando como factores asociados: comorbilidades (obesidad, desnutrición proteico calórica, anemia carencial y depresión), factores clínico-quirúrgicos (adherencias peritoneales, resección intestinal, cirugía laparoscópica y complicaciones no infecciosas de la herida) y administrativos o asistenciales. Conclusiones. La infección temprana, aunque infrecuente, se asocia con un aumento significativo en el riesgo de complicaciones. La optimización prequirúrgica con base en los factores de riesgo para este desenlace nefasto es un elemento clave para la reducción de la incidencia y mitigación del impacto de la infección en los pacientes con herniorrafía incisional con malla.

Introduction. Mesh infection in abdominal wall hernia repair surgery has poor outcome, associated with an increased risk of complications. The objective of this study was to analyze the incidence, associated factors, and outcomes in patients undergoing incisional herniorrhaphy with mesh and subsequent diagnosis of early infection.Methods. Retrospective cohort study. Hospital discharge data from the National Inpatient Sample (NIS) of the United States of America were used to identify all adult patients undergoing incisional herniorrhaphy during the years 2010 to 2015. Bivariate and multivariate logistic regression models were used to evaluate risk factors in early mesh infection, and finally, logistic and linear regression models, according to the type of dependent variable, of the stepwise forward type to evaluate the association between the diagnosis of mesh infection and adverse outcomes.Results. A total of 63,925 patients were included. The incidence of early infection of the mesh was 0.59%, finding as associated factors: comorbidities (obesity, protein-caloric malnutrition, deficiency anemia and depression), clinical-surgical factors (peritoneal adhesions, intestinal resection, laparoscopic surgery and surgical site complications) and administrative or healthcare.Conclusions. Early infection, although rare, is associated with a significantly increased risk of complications. Pre-surgical optimization based on risk factors for this poor outcome is a key element in reducing the incidence and mitigating the impact of infection in patients with mesh incisional herniorrhaphy.

Incisional hernia repair in rats: description of the sublay technique under videomagnification system

Purpose: To describe the technique of sublay correction of incisional hernia in Wistar rats under videomagnification system. Methods: Five male rats of the species Rattus norvegicus, of the Wistar lineage, with body weight between 250­350 g and 60 days old were used. Incisional hernia was inducted in all animals. After that, the incisional hernia was immediately corrected by the sublay method. Results: There were no cases of recurrence of the incisional hernia after placement of the polypropylene mesh using the sublay technique. No postoperative complications were observed. Conclusions: The technique is suitable for execution in Wistar rats.

Fístula enterocutánea en una hernia incisional / Enterocutaneous fistula in an incisional hernia

Introducción: Los defectos técnicos en el cierre de la laparotomía, como la utilización de suturas inadecuadas, muy apretadas o distancia incorrecta entre los puntos, presencia de cuerpos extraños, hematomas o la inclusión de un asa intestinal (pellizcamiento de esta), pueden provocar la aparición de una hernia incisional, y peor aún acompañarse de una fístula intestinal. Objetivo: Corroborar la importancia del cierre correcto y cuidadoso de la pared abdominal después de una laparotomía. Presentación del caso: Se trata de una paciente de 34 años de edad con antecedentes de tres cesáreas en un período de seis años, la última hace seis meses, que fue atendida en el Hospital Mnazi Mmoja, en Tanzania, refiriendo salida de contenido líquido amarillento a nivel de la cicatriz quirúrgica. Al examen físico se constata hernia incisional y un asa intestinal adherida a la piel con un orificio de menos de un cm por donde sale contenido intestinal amarillento. Se interviene con diagnóstico preoperatorio de hernia incisional y fístula enterocutánea; se realiza resección de 3 tres cm del íleon, anastomosis termino-terminal donde se encuentra el orificio fistuloso y hernioplastia mediante la técnica de Rives con utilización de malla de polipropileno. La evolución posoperatoria fue satisfactoria. Conclusiones: Se refuerza la afirmación que es de suma importancia el cierre correcto y cuidadoso de la pared abdominal después de una laparotomía, sobre todo si se realiza con urgencia(AU)

Introduction: In the closure of the laparotomy, technical defects such as the use of inadequate sutures, too tight or incorrect distance between stitches, the presence of foreign bodies, hematomas or the inclusion of an intestinal loop (pinching) can cause the appearance of an incisional hernia which, even worse, can be accompanied by an intestinal fistula. Objective: To corroborate the importance of the correct and careful closure of the abdominal wall after performing laparotomy. Case presentation: A 34-year-old patient with a history of three previous cesarean sections in a six-year period, the last one performed six months, was treated at the Mnazi Mmoja Hospital in Tanzania when she reported the release of a yellowish liquid content at the surgical scar level. Physical examination revealed an incisional hernia and an intestinal loop attached to the skin with a hole of less than one cm through which yellowish intestinal content was coming out. She was operated on with the preoperative diagnosis of incisional hernia and enterocutaneous fistula; a three-cm resection of the ileum, end-to-end anastomosis where the fistulous orifice was located, and hernioplasty were performed using the Rives technique with polypropylene mesh. The postoperative evolution was satisfactory. Conclusions: The assertion that correct and careful closure of the abdominal wall after laparotomy is of utmost importance, especially if it is performed urgently, is reinforced(AU)

Abdomen abierto y cierre temprano de la pared abdominal / Open abdomen and early closure of the abdominal wall

El abdomen abierto es una opción terapéutica en pacientes críticamente enfermos. Se utiliza cuando el cierre de la cavidad abdominal no puede o no debe ser realizado. No obstante, su utilidad como parte de una estrategia tradicionalmente aceptada ha disminuido, en la medida en que se han incrementado las secuelas en la pared abdominal, en especial la hernia ventral. Los procedimientos requeridos para la reconstrucción anatómica y funcional de la pared abdominal, como parte del tratamiento de una hernia ventral, revisten una alta complejidad y constituyen un nuevo escenario quirúrgico. Igualmente, conllevan incertidumbre respecto a su naturaleza y posibles complicaciones, además de que condicionan mayores gastos al sistema de salud. Para evitar los problemas del cierre tardío de la pared abdominal, se han desarrollado alternativas para superar el abordaje tradicional de "tratar y esperar", hacia "tratar y reconstruir" tempranamente. El objetivo de la presente revisión es realizar una descripción de los principales avances en el tratamiento del abdomen abierto y el papel del cierre temprano de la pared abdominal, haciendo énfasis en la importancia de un cambio conceptual en el mismo

The open abdomen is a therapeutic option in critically ill patients. It is used when the closure of the abdominal cavity cannot or should not be performed. However, its usefulness as part of a traditionally accepted strategy has diminished, as sequelae in the abdominal wall, especially ventral hernia, have increased. The procedures required for the anatomical and functional reconstruction of the abdominal wall, as part of the treatment of a ventral hernia, are highly complex and constitute a new surgical scenario. Likewise, they lead to uncertainty regarding their nature and possible complications, in addition to conditioning higher expenses for the health system. To avoid the problems of delayed closure of the abdominal wall, alternatives have been developed to overcome the traditional "try and wait" approach to "treat and reconstruct" early. The objective of this review is to describe the main advances in the treatment of the open abdomen and the role of early closure of the abdominal wall, emphasizing the importance of a conceptual change in it

Robotic trans-abdominal preperitoneal approach (tapp) approach for lateral incisional hernias / Abordagem robótica transabdominal pré-peritoneal (rtapp) para hérnias incisionais laterais

ABSTRACT Background: Lateral incisional hernias arise between the linea alba and the posterior paraspinal muscles. Anatomical boundaries contain various topographic variations, such as multiple nearby bony structures and paucity of aponeurotic tissue that make it particularly challenging to repair. Aim: To describe a robotic assisted surgical technique for incisional lumbar hernia repair. Methods: Retrospective data was collected from four patients who underwent robotic-assisted repair of their lumbar hernias after open nephrectomies. Results: Age ranged from 41-53 y. Two patients had right sided flank hernias while the other two on the left. One patient had a recurrent hernia on the left side. The patients were placed in lateral decubitus position contralateral to the hernia defect side. A trans-abdominal preperitoneal approach was used in all cases. Each case was accomplished with two 8 mm robotic ports, a 12 mm periumbilical port, and a 5 mm assistance port that allowed docking on the ipsilateral hernia side. The hernias were identified, a preperitoneal plane was created, and the hernia sac completely dissected allowing for complete visualization of the defect. All defects were primarily closed. Polypropylene or ProGripTM mesh was applied with at least 5 cm overlap and secured using either #0 Vicryl® transfacial sutures, Evicel® or a combination of both. The peritoneal space was closed with running suture and the ports were removed and closed. The average surgical length was 4 hr. The post-operative length of stay ranged from 0-2 days. Conclusion: The robotics platform may provide unique advantages in the repair of lateral incisional hernias and represents a safe, feasible and effective minimally invasive approach for the correction of lateral incisional hernias.

RESUMO Racional: As hérnias incisionais laterais surgem entre a linha alba e os músculos paravertebrais posteriores. Os limites anatômicos contêm várias variações topográficas, como várias estruturas ósseas próximas e escassez de tecido aponeurótico que tornam o reparo particularmente difícil . Objetivo: Descrever uma técnica assistida por robótica para o reparo de hérnia lombar incisional. Métodos: Dados foram coletados retrospectivamente de quatro pacientes que foram submetidos ao reparo de hérnia lombar após nefrectomias abertas por técnica robótica. Os pacientes tinham entre 41-53 anos de idade. Dois possuíam hérnia no flanco direito e os outros dois no flanco esquerdo. Resultados: Os pacientes foram colocados em posição de decúbito lateral contralateral ao lado do defeito. Abordagem pré-peritoneal transabdominal foi realizada em todos os casos. Cada procedimento foi realizado com dois trocárteres robóticos de 8 mm, um periumbilical de 12 mm e um auxiliar de 5 mm, permitindo docking ipsilateral ao lado da hérnia. As hérnias foram identificadas, plano pré-peritoneal foi criado e o saco herniário completamente dissecado, permitindo completa visualização do defeito. Todos os defeitos foram fechados primariamente com fio de sutura 0/1V-Loc. Tela de polipropileno ou ProGripTM foi usada com pelo menos 5 cm de overlap e fixada com sutura transfacial com Vicryl® 0, Evicel® ou combinação dos dois. O espaço pré-peritoneal foi fechado com sutura contínua e os trocárteres removidos. O tempo operatório médio foi de 4 h. O tempo de permanência hospitalar variou entre 0-2 dias. Conclusão: A plataforma robótica é capaz de providenciar vantagens únicas no reparo de hérnias incisionais laterais e representa abordagem minimamente invasiva segura, factível e eficaz para o reparo das hérnias laterais incisionais.

Endoscopic transposition with the hernial sac (eTHS) in ventral hernia repair - technical description / Transposição endoscópica do saco herniário (TeSH) no tratamento da hérnia ventral - descrição da técnica

ABSTRACT Incisional hernia is a late complication of the most frequent after abdominal surgeries, with resulting morbidity that can worsen the condition. The treatment has been done both by open techniques, using screens or not, and by laparoscopic and robotic methods, which use them systematically. However, introducing a permanent foreign body into the tissues requires more surgical time, despite not closing the parietal defect in most cases and a higher risk of infections. New technologies have been trying to improve these results, with absorbable prostheses (biological or synthetic), but their high cost and recurrences remain a severe problem. Even so, standard repair establishes reinforcement with screens, routine, and whether the approach is traditional or mini-invasive. The authors report their first case of endoscopic repair of incisional hernia, which occurred two years ago, with a Brazilian technique already fifty years old: the transposition with the hernia sac proposed by Prof. Alcino Lázaro da Silva in 1971.

RESUMO A hérnia incisional é uma das complicações tardias mais frequentes, após operações abdominais, resultando em alta morbidade. O tratamento tem sido feito tanto por técnicas abertas, com telas ou sem, quanto por métodos laparoscópicos e robóticos, que utilizam próteses de forma sistemática. No entanto, a introdução de um corpo estranho permanente entre os tecidos requer mais tempo cirúrgico, não fecha o defeito parietal na maioria dos casos e está associado a maior risco de infecções. Novas tecnologias têm sido utilizadas para melhorar esses resultados, empregando próteses absorvíveis (biológicas ou sintéticas), mas o alto custo e as recidivas continuam sendo um grave problema. No entanto, a reparação padrão rotineiramente estabelece reforço com telas, seja na abordagem tradicional ou minimamente invasiva. Os autores relatam o primeiro caso do reparo endoscópico de hérnia incisional, usando técnica brasileira com 50 anos de idade: a transposição com o saco herniário, conforme proposta pelo Prof. Alcino Lázaro da Silva, em 1971.

Hernia incisional en laparotomía de McBurney: complicaciones de una hernia inusual / Incisional hernia after McBurney incision: complications of an unusual hernia

Resumen Introducción Actualmente, la mayoría de las series que hablan sobre hernia incisional, no mencionan hernias incisionales en laparotomías de McBurney. La incidencia reportada de hernia incisional en esta laparotomía varía entre 0,7% y 2%. Aún más escasas son las publicaciones sobre sus complicaciones. El objetivo del presente reporte de casos es el de discutir el diagnóstico, tratamiento y resultados de dos pacientes operados en nuestra institución por hernia de McBurney complicada. Reporte de Casos: Se describen 2 pacientes femeninos de 68 y 65 años de edad que fueron operadas de urgencia por hernia incisional en laparotomía de McBurney complicada. La evolución postoperatoria fue diferente en ambas y una de ellas falleció. Discusión Se discuten los factores de riesgo para el desarrollo de estas hernias, el diagnóstico y tratamiento. Además, se discute la importancia de la apendicectomía laparoscópica para la prevención de estas hernias. Conclusiones Las complicaciones de la hernia en laparotomía de McBurney, las cuales son severas y potencialmente letales, se diagnostican tardíamente debido al retraso en la presentación y en el diagnóstico. La amplia utilización de la cirugía laparoscópica para la apendicectomía seguramente reducirá aún más la incidencia de este tipo de hernia durante los próximos años.

Introduction Currently, most series over incisional hernia do not mention this hernia occurring in McBurney's laparotomy. The reported incidence for this type of hernia is 0.7% to 2%. Even more scarce are publications regarding its complications. The purpose of this report is to discuss the diagnostic, treatment and outcomes of two patients operated on our institution for complicated McBurney´s hernia. Report of Cases: Two female patients 68 and 65 years-old operated on emergency grounds for complicated incisional hernia over a McBurney´s incision are described. Postoperative evolution was different in both cases and one of them died. Discussion We discuss risk factor for this specific incisional hernia development, its diagnosis and treatment. Besides, the importance of laparoscopic appendectomy was stressed. Conclusions Complicated incisional hernia over McBurney's incision is an infrequent severe clinical condition habitually diagnosed late. The widespread utilization of laparoscopic appendectomy will reduce even more the incidence of this kind of hernia within the next few years.

Incisional hernia, a rare complication of the anterolateral transpsoas approach / Hernia incisional, una complicación poco frecuente del abordaje transpsoas anterolateral

Abstract: Introduction: Anterolateral transpsoas approach is considered as safe access to the retroperitoneum with low risk of complications. The most frequent described complications due to this approach were nerve, bowel, urethral and kidney injury. An incisional hernia is a rare complication in anterolateral approach, as a result of a nonhealing surgical wound or late disruption of the fascia; it occurs in 1% of the incisions after primary closure. Case description: We report a 75-year-old woman who underwent spinal surgery with a double approach, consisting of an anterolateral transpsoas approach and posterior lumbar approach. Two months post-surgery, the patient developed a lateral abdominal tumor at the surgical site. Conclusion: To prevent incisional hernia, a meticulous dissection must be performed to avoid muscle denervation and weakening of the abdominal wall, as well as proper repair of the fascia its critical to ensure an adequate closure of the wound.

Resumen: Introducción: El Abordaje anterolateral transpsoas se considera como un acceso seguro al retroperitoneo con bajo riesgo de complicaciones. Las complicaciones descritas más frecuentes debido a este abordaje fueron lesiones nerviosas, intestinales, uretrales y renales. Una hernia incisional es una complicación poco frecuente en el abordaje anterolateral, como resultado de una herida quirúrgica no cicatrizada o una ruptura tardía de la fascia; ocurre en 1% de las incisiones después del cierre primario. Caso clínico: Informamos de una mujer de 75 años que se sometió a una cirugía de columna vertebral con un doble abordaje quirúrgico, que consiste en un abordaje anterolateral transpsoas y un abordaje lumbar posterior. Dos meses después de la cirugía, el paciente desarrolló un tumor abdominal lateral en el sitio quirúrgico. Conclusión: Para prevenir la hernia incisional, se debe realizar una disección meticulosa para evitar la denervación muscular y el debilitamiento de la pared abdominal, así como la correcta reparación de la fascia es crítico para asegurar un cierre adecuado de la herida.

Incisional hernioplasty techniques: analysis after open bariatric surgery / Análise das técnicas de hernioplastia incisional após cirurgia bariátrica aberta

ABSTRACT Background: The best technique for incisional hernioplasty has not been established yet. One of the difficulties to compare these techniques is heterogeneity in the profile of the patients evaluated. Aim: To analyze the results of three techniques for incisional hernioplasty after open bariatric surgery. Method: Patients who underwent incisional hernioplasty were divided into three groups: onlay technique, simple suture and retromuscular technique. Results and quality of life after repair using Carolina's Comfort Scale were evaluated through analysis of medical records, telephone contact and elective appointments. Results: 363 surgical reports were analyzed and 263 were included: onlay technique (n=89), simple suture (n=100), retromuscular technique (n=74). The epidemiological profile of patients was similar between groups. The onlay technique showed higher seroma rates (28.89%) and used a surgical drain more frequently (55.56%). The simple suture technique required longer hospital stay (2.86 days). The quality of life score was worse for the retromuscular technique (8.43) in relation to the onlay technique (4.7) and the simple suture (2.34), especially because of complaints of chronic pain. There was no difference in short-term recurrence. Conclusion: The retromuscular technique showed a worse quality of life than the other techniques in a homogeneous group of patients. The three groups showed no difference in terms of short-term hernia recurrence.

RESUMO Racional: A melhor técnica de hernioplastia incisional ainda não foi definida. Uma das dificuldades na comparação é a heterogenicidade no perfil dos pacientes avaliados. Objetivo: Analisar os resultados de três técnicas de hernioplastia incisional após cirurgia bariátrica aberta. Método: Os pacientes que realizaram hernioplastias incisionais foram estudados e divididos em três grupos: técnica onlay, sutura simples e técnica retromuscular. Resultados e qualidade de vida após o reparo utilizando o Carolina's Comfort Scale foram avaliados através de análise de prontuários, contato telefônico e consultas eletivas. Resultados: Foram analisados 363 relatos cirúrgicos e 263 foram incluídos: técnica onlay (n=89), sutura simples (n=100), técnica retromuscular (n=74). O perfil epidemiológico dos pacientes foi similar entre os grupos. A técnica onlay apresentou maiores taxas de seroma (28,89%) e usou dreno com maior frequência (55,56%). A sutura simples obteve maior tempo de internação (2,86 dias). O escore de qualidade de vida foi pior na técnica retromuscular (8,43) em relação à onlay (4,7) e à sutura simples (2,34), especialmente devido às queixas de dor crônica. Não houve diferença quanto a recidiva em curto prazo. Conclusão: A técnica retromuscular apresentou pior qualidade de vida do que as demais técnicas em um grupo homogêneo de pacientes. Os três grupos não mostraram diferenças em termos de recidiva de hérnia em curto prazo.

Maximum inspiratory and expiratory pressures in the pre and postoperative periods of patients with incisional abdominal hernia corrected by Lázaro da Silva technique / Pressões máximas inspiratórias e expiratórias no pré e pós-operatório de pacientes com hérnias incisionais abdominais corrigidas pela técnica de Lázaro da Silva

ABSTRACT Objective: To verify the effect of longitudinal abdominal incisional herniorrhaphy on respiratory muscle pressure. Method: The technique of incisional herniorrhaphy used was proposed by Lázaro da Silva. To measure the pressure, we used a water manometer in 20 patients, median age 48.5 years (range 24 70). We analyzed the maximum inspiratory pressure at the level of residual volume (IP-RV) and functional residual capacity (IP-FRC) and the maximum expiratory pressure of functional residual capacity (EP-FRC) and total lung capacity (EP-TLC) in the preoperative and late postoperative (40 90 days) periods, in 13 patients with large incisional hernias and in 7 patients with medium incisional hernias. Results: There was a significant increase in IP-FRC (p = 0.027), IP-RV (p = 0.011) and EP-TLC (p = 0.003) in patients with large incisional hernias. EP-FRC increased, but not significantly. In patients with medium incisional hernias, the changes were not significant. Conclusion: Surgical correction of large incisional hernias improves the function of the breathing muscles; however, surgery for medium incisional hernias does not alter this function.

RESUMO Objetivo: verificar o efeito da herniorrafia incisional abdominal longitudinal na pressão dos músculos da respiração. Método: a técnica de herniorrafia incisional utilizada foi a proposta por Lázaro da Silva. Para aferir a pressão foi utilizado manômetro de água, em 20 pacientes, idade mediana 48,5 anos (mínimo 24, máximo 70). Foram analisadas a pressão máxima inspiratória no nível do volume residual (PIVR) e da capacidade residual funcional (PICRF) e a pressão máxima expiratória da capacidade residual funcional (PECRF) e da capacidade pulmonar total (PECPT), no pré-operatório e pós-operatório tardio (entre 40 e 90 dias), em 13 pacientes com hérnias incisionais grandes e em 7 pacientes com hérnias incisionais médias. Resultados: houve aumento significante da PICRF (p=0.027), da PIVR (p=0.011), da PECPT (p=0.003) nos pacientes com hérnias incisionais grandes. A PECRF aumentou, porém de forma não significante. Nos pacientes com hérnias incisionais médias as alterações não foram significantes. Conclusão: a correção cirúrgica da hérnia incisional grande melhora a função dos músculos da respiração, porém a cirurgia da hérnia incisional média não altera a referida função.
