The evolution of incisional hernia repair in Spain. A comparative analysis of results from the EVEREG registry.

BACKGROUND: The aim of this study was to assess the utility of the EVEREG registry in evaluating the evolution of surgical treatment for incisional hernia and its outcomes in Spain by comparing data from 2 study periods. METHODS: A retrospective comparative analysis of hernia surgeries performed between 2011 and 2015 (first period) and between 2017 and 2022 (second period) was conducted using data collected from the EVEREG registry. RESULTS: Statistically significant differences were observed in the second cohort, including: a decrease in minimally invasive procedures (11.7% vs 8.2%; P < .001), an increase in emergency surgeries for males (31.7% vs 41.2%; P = .017), an increase in trocar hernia repairs (16% vs 26.2%; P < .0001), a reduction in suture repairs (2.8% vs 1.5%; P < .0001), and an increase in retromuscular techniques (36.4% vs 52.4%; P < .001) in open surgery with mesh. In elective surgery, there was a decrease in the average length of stay (4.9 vs 3.8 days; P < .0001), the percentage of complications (27.9% vs 24.0%; P < .0001), reoperations (3.5% vs 1.4%; P < .0001), and mortality (0.6% vs 0.2%; P = .002). Long-term outcomes included a decrease in recurrences after 12 months (20.7% vs 14.5%; P < .0001) and in chronic pain (13.7% vs 2.5%; P < .0001) and chronic infections (9.1% vs 14.5%; P < .0001) after 6 months. CONCLUSION: In recent years, there has been a significant improvement in the outcomes of incisional hernia treatment. The registry serves as a fundamental tool for assessing the evolution of hernia treatment and enables the identification of key areas for improvement and the evaluation of treatment outcomes.

Use of botulinum toxin type A in the prehabilitation of abdominal wall musculature for hernia repair: a consensus proposal.

The prehabilitation of the abdominal wall through the infiltration of botulinum toxin type A, which induces temporary chemical denervation ("chemical component separation") in the lateral abdominal musculature, is a common practice in units specialized in abdominal wall surgery. However, its use for this indication is currently off-label. The main objective of this article is to describe a consensus proposal regarding indications, contraindications, dosages employed, potential side effects, administration method, and measurement of possible outcomes. Additionally, a proposal for an informed consent document endorsed by the Abdominal Wall Section of the Spanish Association of Surgeons is attached.

Experiencia del tratamiento de la hernia incisional en un hospital de tercer nivel en Colombia / Experience of the treatment of incisional hernia in a third level hospital in Colombia

Introducción. El manejo de las hernias se ha instaurado como un problema quirúrgico común, estimándose su aumento en los próximos años. El objetivo del presente trabajo fue describir el curso clínico, los aspectos del tratamiento quirúrgico y factores asociados a la presencia de complicaciones en pacientes intervenidos por hernia incisional. Métodos. Estudio descriptivo en el que se analizaron las características de una cohorte de pacientes llevados a corrección quirúrgica de hernia incisional en el Hospital Universitario Hernando Moncaleano Perdomo, un centro de alta complejidad en Neiva, Colombia, entre 2012 y 2019. Los datos fueron recolectados en programa Microsoft Excel® y analizados en SPSSTM, versión 21. Resultados. Se realizaron 133 correcciones de hernias incisionales, 69,9 % en mujeres y la mayoría ubicadas en la línea media (84,2 %). La edad media de los pacientes al momento de la intervención fue de 52 años ±14,6. Las comorbilidades más frecuentes fueron obesidad, hipertensión y diabetes. La causa más frecuente de la hernia fue traumática (61,7 %). 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

El objetivo de este estudio fue describir las características de la población y determinar las principales complicaciones de los pacientes que son llevados a cirugía por hernia lateral en el abdomen. Métodos. Estudio observacional retrospectivo, que incluyó a los pacientes sometidos a herniorrafia lateral, entre 2015 y 2019 en un centro de tercer nivel. La información se obtuvo del registro de historias clínicas. Las variables analizadas se clasificaron según las características sociodemográficas de los pacientes, clínicas y quirúrgicas. Se hizo una caracterización de acuerdo con los resultados encontrados. Resultados. Se incluyeron 51 pacientes con hernia lateral, 29 de ellos mujeres, con un promedio de edad de 59 años y de índice de masa corporal de 28 kg/m2. El 60 % tenía comorbilidades de base, siendo la hipertensión arterial la más frecuente. La mayoría se clasificaron como ASA II. En cuanto a la localización, la L3 fue la más común (37,2 %). Se presentaron complicaciones postquirúrgicas en el 27,4 % de los pacientes, siendo las más frecuentes seromas, hematomas e infecciones de sitio operatorio. Ningún paciente requirió reintervención para el manejo de las complicaciones. Conclusión. Conocer la población y determinar cuáles son las principales complicaciones postquirúrgicas de un procedimiento permite tomar medidas para disminuir su frecuencia, pero en este caso, se necesitan estudios adicionales para determinar cuáles son los mayores factores asociados a las complicaciones

Introduction. To describe the characteristics of the population and to determine the main complications of patients who undergo surgery for lateral hernia. Methods. We performed a retrospective observational study, including patients who underwent lateral herniorrhaphy between 2015 and 2019 in a third-level medical center, obtaining information through the registration of medical records. The analyzed variables were classified according to the patients' clinical, surgical and sociodemographic characteristics, performing a characterization according to the results found. Results. Fifty-one patients due to lateral hernia were included, 29 of them were women, with a mean age of 59 years and a body mass index of 28 Kg/m2. Of those, 60% presented basic comorbidities, being arterial hypertension the most frequent. Most were classified as ASA II. Regarding the location, the L3 was the most commonly presented hernia, referring to 37.2%. Postoperative complications occurred in 27.4% of the patients, with seromas being the most frequent, followed by hematomas and surgical site infections. No patient required reintervention for the management of complications. Conclusion. By knowing the population and determining which are the main complications, measures can be taken to reduce their incidence. Additional studies are needed to determine which are the main factors associated with complications

Encuesta nacional a unidades de cirugía colorrectal sobre el cierre de pared abdominal / National survey of colorectal surgery units on abdominal wall closure

Introducción: El objetivo de este estudio es valorar el estado actual y conocimiento de los cirujanos colorrectales españoles en el cierre de pared abdominal. Métodos: Se realizó un cuestionario de 25 preguntas cerradas de respuesta única utilizando un software específico para encuestas online que se distribuyó a cirujanos que se dedican, principalmente, a la cirugía colorrectal en su servicio o pertenecen a una Unidad de Cirugía Colorrectal. Resultados: Respondieron la encuesta 53 cirujanos. La mayoría prefiere el cierre de la laparotomía media con una sutura continua (96,23%) de monofilamento de absorción muy lenta (67,92%) en un solo plano (81,13%). Los puntos en masa, los sistemas de retención y las suturas loop siguen utilizándose. El calibre de sutura habitualmente más utilizado fue del 1 USP (United States Pharmacopeia) (58,49%). La aguja más utilizada es de cuerpo cilíndrico y punta trocar. Solo el 50% realiza habitualmente cierre de la pared tras colocación de un trocar igual o mayor de 10mm. Prácticamente todos conocen la regla del 4:1 y creen que se debe aplicar, pero la técnica de puntos cortos no se realiza. El 50% no colocaría nunca una prótesis profiláctica. El cierre lo suele realizar el mismo cirujano que ha llevado a cabo todo el procedimiento. Uno de cada 5 confiesa desconocer la tasa de hernias incisionales de su unidad. Conclusiones: Se evidencia una falta de consenso y conocimientos básicos en cuanto a los aspectos técnicos de cierre y a la prevención de la aparición de hernias incisionales. Parece aceptado el uso de sutura continua, en un solo plano, con sutura monofilamento de reabsorción lenta. (AU)

Introduction: The purpose of this study is to assess the current status and knowledge of the Spanish colorectal surgeons on the wall closure. Methods: A single answer questionnaire of 25 closed questions was conducted using specific software for online surveys that was distributed to a cohort of colorectal surgeons. Results: 53 surgeons replied to the survey. The vast majority prefer a closure of the midlaparotomy with a very slow absorbing monofilament (67,92%) continuous suture (96,23%) in a single plane (81,13%). Mass stitches, retention systems, and loop sutures continue to be used. The most commonly used suture gauge was USP 1 (United States Pharmacopeia) (58,49%). The most commonly used needle is with a cylindrical body and a trocar tip. Only 50%, routinely perform wall closure after placement of a trocar equal to or greater than 10mm. Almost everyone knows the 4: 1 rule and thinks it should be applied, but the small bites technique is not performed. 50% would never place a prophylactic prosthesis. The closure is usually performed by the same surgeon who has performed the entire procedure. One out of five confesses not knowing the rate of incisional hernias in his unit. Conclusion: There is a lack of consensus and basic knowledge regarding the technical aspects of closure and the prevention of the appearance of incisional hernias. The use of slow absorbing monofilament continuous suture in a single plane seems well accepted. (AU)

Optimización de neumoperitoneo preoperatorio en hernia ventral: Uso de un dispositivo de compresión externa

La hernia incisional compleja es un desafío para el cirujano. Son ampliamente conocidos los factores que han permitido mejorar los resultados de la reparación herniaria, entre ellos el neumoperitoneo preoperatorio. Durante la insuflación preoperatoria, el aire difunde tanto en la cavidad abdominal como en el saco herniario. Sin embargo, gran porcentaje del contenido administrado, se distribuye mayormente en el saco herniario y no en la cavidad abdominal. En Latinoamérica, diversos equipos de cirujanos de pared abdominal han compartido experiencias en lo que respecta a la optimización de esta técnica como adyuvancia para el manejo de las hernias complejas. En este contexto, y para optimizar la distribución del aire insuflado hacia la cavidad abdominal, se comenzó a utilizar un dispositivo externo de compresión. Este trabajo busca estandarizar por primera vez esta técnica durante el neumoperitoneo preoperatorio buscando disminuir el volumen de aire insuflado, los días de neumoperitoneo y, por lo tanto, los días de hospitalización previo a la cirugía.

Complicated incisional hernia is challenging for surgeons. The factors that have improved the results of hernia repair are widely known, including preoperative pneumoperitoneum. During preoperative insufflation, air diffuses into both the abdominal cavity and the hernia sac. However, a large percentage of the administered content is distributed mainly in the hernia sac and not in the abdominal cavity. Latin-American teams of abdominal wall surgeons have shared experiences regarding the optimization of this technique as an adjuvant for the management of complicated hernias. In this context and to optimize the distribution of the insufflated air into the abdominal cavity, an external compression device began to be used. This article aims to standardize this technique for the first time during preoperative pneumoperitoneum. The target is to reduce the volume of air insufflated, the days of pneumoperitoneum and, therefore, the days of hospitalization prior to surgery.

Introduction. Managing ventral hernia remains a challenge for surgeons. Repairing it using minimally invasive techniques, such as laparoscopic totally extraperitoneal (eTEP), which allows for a wide dissection of the space to be repaired, faster postoperative recovery, less postoperative pain and shorter hospital stay. The eTEP approach is a novel technique that focus on the uses of the retromuscular space to place prosthetic material and strengthen the abdominal wall. The objective is to describe the short-term results of our initial experience with the eTEP technique in the management of ventral hernias. Methodology. Observational, descriptive, retrospective, study, which included patients with a diagnosis of ventral hernia, undergoing laparoscopic eTEP surgery, between July-2021 and June-2022. Results. Of a total of 21 patients, 61.9% were men. 47.6% were overweight and 52.4% were obese. Average hospital stay: 1.6 days. 66.7% were incisional hernias. The surgical techniques performed were: Rives-Stoppa (71.4%) with associated transversus abdominis muscle release in 28.6%. 19% of the patients presented global complications and only one was severe, requiring surgical reintervention. The presence of clinical seroma was observed in 9.5% and ultrasound in 57.1%. There was no evidence of hematomas, surgical wound infection or cases of hernia recurrence. Discussion and conclusions. The laparoscopic-eTEP Rives-Stoppa approach, associated or not with posterior separation of components, in the management of ventral hernias offers good results with a low incidence of postoperative complications, short hospital stay, low incidence of hernia recurrences, so it could be considered a safe and effective technique in the treatment of ventral hernias.

Impacto del sitio de extracción en la incidencia de hernias incisionales en pacientes sometidos a cirugía laparoscópica por cáncer colorrectal

Introducción: El objetivo de este estudio fue comparar la tasa de hernia incisional (HI) tras la extracción de piezas operatorias por mini-laparatomia media periumbilical (MM) versus mini-laparotomía transversa suprapúbica (MTS) en pacientes sometidos a cirugía laparoscópica por cáncer colorrectal (CLCC), y evaluar los factores asociados a su ocurrencia. Material y Método: Estudio de cohorte no concurrente. Se incluyen todos los pacientes consecutivos sometidos a CLCC en nuestro centro entre septiembre 2006 y diciembre 2017, cuya pieza operatoria fuese extraída por una MM o MTS y que contaran con un control tomográfico en el seguimiento. El diagnóstico de HI se realizó mediante tomografía computada, evaluada por dos radiólogos de forma independiente. Se agruparon los pacientes en MM y MTS, y se evaluaron las tasas de HI según sitio de extracción. Además, se realizó una regresión logística para identificar factores asociados a HI. Resultados: Se identificaron 1090 pacientes que tuvieron resecciones colorrectales lapa-roscópicas durante el período estudiado. De estos, 254 cumplieron con los criterios de inclusión. La edad media de la serie fue de 63 años (53,5% son hombres) con un IMC de 26,4 kg/m2. El sitio de extracción fue una MTS en un 53,1% y una MM en un 46,9%. Se identificó un total de 41 (34,5%) HI en el grupo de MM versus 17 (12,6%) en MTS (p = 0,001) en la TC de seguimiento realizado en una mediana de 18 meses (RIC 12-32) postoperatorios. En la regresión logística, el sitio de extracción (OR = 3,33, IC 95% 1,72-7,14, p < 0,001) y la presencia de patología bronquial obstructiva se asociaron de manera independiente con HI (OR = 3,45, IC 95% 1,11-11,11, p = 0,03). Conclusión: La MTS se asocia a una menor tasa de HI que la MM en pacientes sometidos a CLCC. Esto se debe tener en consideración al momento de elegir el sitio de extracción de pieza operatoria en CLCC.

Aim: To compare the rate of incisional hernia (IH) according to the extraction site in patients undergoing laparoscopic colorectal cancer surgery (LCCS), and to evalúate the risk factors associated with its occurrence. Material and Method: Cohort study including all consecutive patients undergoing LCCS in our center between September 2006 and December 2017, where the specimen was extracted through a median mini-laparotomy (MM) or transverse suprapubic mini-laparotomy (TSM) and have a tomographic control during follow-up. The diagnosis of IH was made by computed tomography evaluated by two radiologists, independently. The rate of IH was calculated for both groups and a regression analysis were performed to identify factors associated with IH. Results: Some 1090 patients undergoing laparoscopic colorectal resections were identified during the study period; of these, 254 met the inclusion criteria. The mean age of the series was 63 years (53.5% are men) with a BMI of 26.4 kg/m2. The extraction site was a TSM in 53.1% and a MM in 46.9%. A total of 41 (34.5%) IH were identified in the MM group versus 17 (12.6%) in TSM (p = 0.001) in the follow-up CT performed at a median of18 months (IQR 12-32) postoperative. In logistic regression, the extraction site (OR = 3.33, 95% CI 1.72-7.14, p < 0.001) and the presence of obstructive bronchial pathology were independently associated with IH (OR = 3, 45, 95% CI 1.11-11.11, p = 0.03). Conclusión: A TSM is associated with a lower rate of IH compared to a MM as extraction site in patients undergoing LCCS. This must be taken into account when choosing the extraction site in patients having LCCS.

Neumoperitoneo progresivo preoperatorio para el tratamiento de la hernia inguinoescrotal gigante: reporte de caso / Progressive Preoperative Pneumoperitoneum for Giant Inguinoscrotal Hernia: a Case Report

Resumen Introducción: El procedimiento de neumoperitoneo progresivo preoperatorio para el manejo de hernias gigantes con "Pérdida de dominio" o Pérdida de derecho a domicilio" fue introducido en 1940 por Goñi Moreno en Argentina. Autores como Herszage, Berlemont, Koontz, Gravez y Martínez Munive presentaron variaciones interesantes del método original. Su uso se recomienda para preparación previa de pacientes con hernias gigantes y grandes contenidos de vísceras en el saco herniario, en los cuales no sería posible su re-introducción y efectuar la hernioplástia, o en los que su reducción de manera forzada pudiera llevar al paciente al desarrollo de un síndrome compartimental abdominal en el postoperatorio inmediato. Caso clínico: Paciente de sexo masculino de 65 años de edad, que presenta cuadro clínico de un mes de evolución caracterizado por dolor a nivel de la región inguinal izquierda, en el cual se evidencia presencia de hernia inguino escrotal gigante izquierda, no reductible, con aproximadamente un 40% de contenido abdominal. Resultados: La mayoría de los estudios describen el uso del neumoperitoneo progresivo para la reparación de las eventraciones gigantes, sin embargo, en nuestra experiencia y en la de otros autores, esta técnica también puede utilizarse para resolver las hernias inguinales y umbilicales gigantes, con buenos resultados. En todos los casos se aconseja utilizar material protésico. Conclusión: El uso del neumoperitoneo preoperatorio progresivo, se trata de una técnica segura y fácil de realizar que puede complementar las técnicas de eventroplastía complejas, aportando ventajas en la preparación de los pacientes con grandes defectos de pared abdominal y obteniendo buenos resultados.

Abstract Introduction: The procedure of progressive preoperative pneumoperitoneum for the management of giant hernias with "Loss of domain" or "Loss of the right of domain" was introduced in 1940 by Goñi Moreno in Argentina, followed in later years by authors such as Herszage, Berlemont, Koontz, Gravez and Martínez Munive, all with some interesting variations of the original method. Its use is recommended for previous preparation of patients with giant hernias and large contents of viscera in the hernial sac, in which it would not be possible to re-introduce and perform hernioplasty, or in which its forced reduction could lead to the patient to the development of an abdominal compartment syndrome in the immediate postoperative period. Clinical case: A 65-year-old male patient with a clinical picture of one month of evolution characterized by pain in the left inguinal region. There was evidence of a giant left inguinal scrotum, not reducible, with approximately 40% abdominal contents. Results: Most studies describe the use of progressive pneumoperitoneum for the repair of giant hernias, however, in our experience and in that of other authors, this technique can also be used to resolve hernias giant inguinal and umbilical, with good results. In all cases it is recommended use prosthetic material. Conclusion: The use of progressive preoperative pneumoperitoneum is a safe and easy-to-perform technique that can complement complex eventroplasty's techniques, providing advantages in the preparation of patients with large abdominal wall defects and obtaining good results.

Incidence and risk factors for incisional hernia after open abdominal aortic aneurysm repair / Incidencia y factores de riesgo de hernia incisional tras la cirugía abierta del aneurisma de aorta abdominal

Introduction: Incisional hernia (IH) is common after open abdominal aortic aneurysm (AAA) repair. Recent studies reported incidence rates higher than previously stated. The aim of this study was to quantify the IH incidence after open AAA surgery. The secondary outcome was to identify the risk factors associated with the development of an IH. Methods: Retrospective observational study of all consecutive patients who underwent an open repair of AAA, from January 2010 to June 2018, at our institution. Patients were free of abdominal wall hernias at the moment of inclusion in the study. Data were extracted from electronic records: baseline characteristics, surgical factors, and postoperative events. Computed tomography (CT) scans performed during follow-up were analyzed. Results: A total of 157 patients were analysed. The IH incidence after open repair of AAA was 46.5% (73 patients). The median time for IH development was 24.43 months (IQR: 10.40–45.27), while the median follow-up time was 37.20 months (IQR: 20.53–64.12). The risk factors linked to IH were: active (HR: 4.535; 95% CI: 1.369–15.022) or previous smoking habit (HR: 4.652; 95% CI: 1.430–15.131), chronic kidney disease (HR: 2.007; 95% CI: 1.162–3.467) and previous abdominal surgery (HR: 1.653; 95% CI: 1.014–2.695). Conclusion: The incisional hernia after open abdominal aortic aneurysm repair affected a high proportion of the intervened patients. Previous abdominal surgery, chronic kidney disease, and smoking habit were independent factors for the development of an incisional hernia. (AU)

Introducción: La hernia incisional (HI) tras la cirugía abierta del aneurisma de aorta abdominal (AAA) es común. Estudios recientes muestran incidencias superiores a las consideradas anteriormente. El objetivo es evaluar la incidencia de HI tras la cirugía abierta del AAA. El objetivo secundario fue evaluar los factores de riesgo de HI. Métodos: Estudio observacional retrospectivo de pacientes consecutivos sometidos a cirugía abierta del AAA de enero de 2010 a junio de 2018 en nuestro centro. Todos los pacientes estaban libres de hernias de pared abdominal en el momento de la cirugía. Se analizaron los datos de la historia clínica electrónica: características basales, factores quirúrgicos y eventos postoperatorios. Se analizaron también los estudios de tomografía computarizada durante el seguimiento. Resultados: Se analizaron 157 pacientes. La incidencia de HI tras la cirugía abierta del AAA fue del 46,5% (73 pacientes). La mediana de tiempo para el desarrollo de HI fue de 24,43 meses (RIC 10,40-45,27), con una mediana de seguimiento de 37,20 meses (RIC 20,53-64,12). Los factores de riesgo asociados fueron: tabaquismo activo (HR 4,535; IC 95% 1,369-15,022) o hábito tabáquico previo (HR 4,652; IC 95% 1,430-15,131), enfermedad renal crónica (HR 2,007; IC 95% 1,162-3,467) y cirugía abdominal previa (HR 1,653; IC 95% 1,014-2,695). Conclusiones: La HI tras la cirugía abierta del AAA afectó a un gran número de pacientes intervenidos. La cirugía abdominal previa, la enfermedad renal crónica y el hábito tabáquico fueron factores de riesgo independientes de HI. (AU)

The risk factors linked to IH were: active (HR: 4.535; 95% CI: 1.369-15.022) or previous smoking habit (HR: 4.652; 95% CI: 1.430-15.131), chronic kidney disease (HR: 2.007; 95% CI: 1.162-3.467) and previous abdominal surgery (HR: 1.653; 95% CI: 1.014-2.695). CONCLUSION: The incisional hernia after open abdominal aortic aneurysm repair affected a high proportion of the intervened patients. Previous abdominal surgery, chronic kidney disease, and smoking habit were independent factors for the development of an incisional hernia.

Hernia incisional umbilical (M3). ¿Son diferentes las hernias de trócar? Análisis comparativo del registro EVEREG / Umbilical incisional hernias (M3): Are trocar-site hernias different? Comparative analysis of the EVEREG Registry

Introducción La hernia incisional (HI) es una complicación frecuente. El objetivo principal de este estudio es comparar características, complicaciones y recurrencias de las HI producidas por la colocación de un trócar laparoscópico umbilical (M3T) con las de misma localización tras cirugía abierta (M3O); y de forma secundaria, la identificación de factores de riesgo. Método Estudio observacional transversal analizando al registro EVEREG durante el periodo entre julio del 2012 y junio del 2018. Las variables principales fueron recurrencias y complicaciones postoperatorias. Se compararon ambos grupos (M3T y M3O). Se realizó regresión logística múltiple para identificar los factores de riesgo de la cohorte completa. Resultados Se incluyeron un total de 882 casos. El grupo M3O presentó un ASA superior, HI con criterios de mayor complejidad para la reparación, mayor número de recurrencias a los 12 y 24 meses (8,6 vs. 2,5%; p < 0,0001 y 9,3 vs. 2,9%; p < 0,0001, respectivamente) y complicaciones postoperatorias (21,9 vs. 14,6%; p = 0,02). Se identificaron como factores de riesgo para la aparición de complicaciones postoperatorias, la reparación previa, la duración de la intervención y el requerimiento de procedimientos asociados, y para las recidivas: la ausencia de especialista de pared abdominal, la reparación previa y la aparición de complicaciones. El análisis por puntuación de propensión no detectó diferencias significativas en complicaciones y recurrencias. Conclusiones Las HI M3 de trócar umbilical son menos complejas que las originadas por cirugía abierta. La complejidad no se relaciona con el origen de la hernia, sino con sus características y las del paciente (AU)

Introduction Incisional hernia (HI), in open and laparoscopic surgery, is a very frequent complication. HI located in the umbilical region are called M3. The main aim of this study is to compare HI produced by the placement of an umbilical laparoscopic trocar (M3T) with those located in M3 in open surgery (M3O) in terms of basal characteristics, complications and recurrences; and secondarily the identification of risk factors. Method Cross-sectional observational study based on the national prospective registry EVEREG during the period of July 2012 - June 2018. The main variables were recurrences and postoperative complications. Both groups (M3T and M3O) were compared. Multiple logistic regression was performed to identify the risk factors of the entire cohort. Results 882 had a follow-up time longer than 12 months. M3O group presented superior ASA-Class, more complex HI and previous repair. It also presented a higher recurrence rate at 12 and 24 months (8.6 vs. 2.5%; p < 0,0001 and 9.3 vs. 2.9%; p < 0.0001) and higher postoperative complications rate (21.9 vs. 14.6%; p = 0.02). Previous repair, intervention length and associated procedures requirement were identified as risk factors for postoperative complications. Absence of a specialist present during surgery, previous repair, and the absence of complications were identified as risk factors for recurrence. In the PSM analysis no differences were detected in of complications and recurrences. Conclusions HI M3O is more complex than M3T. The complexity is not related to the origin of the hernia but to its characteristics and those of the patient (AU)

Hernia incisional y pérdida de dominio con neumoperitoneo progresivo preoperatorio más separacion de componentes. Un reporte de caso / Progressive preoperative pneumoperitoneum and components separation in incisional hernia with loss of domain. A case study report

Introducción: Una hernia con pérdida de dominio tiene un contenido de saco herniario de 50% o más del contenido de la cavidad abdominal, que conlleva a efectos locales y sistémicos. Reporte de Caso: Presentamos el caso de una paciente con hernia incisional y pérdida de dominio de 30 años de evolución, quien fue sometida a neumoperitoneo preoperatorio y durante acto quirúrgico, para evitar el cierre del defecto herniario con tensión, se realizó separación de componentes. Conclusión: El neumoperitoneo progresivo preoperatorio es un método recomendable en el manejo de pacientes con hernias gigantes y pérdida de dominio, porque es de bajo costo, seguro, fácil de realizar y evita las posibles complicaciones a las que el cierre del defecto con tensión conlleva.

Background:Ahernia with loss of domain has a hernia sac content of 50% or more than the content of the abdominal cavity, which leads to local and systemic effects. The case of a patient with an incisional hernia Report case: with loss of domain and 30 years of evolution is presented, she underwent preoperative pneumoperitoneum and during surgery, anterior component separation was performed to avoid tension in the closure of the hernia defect. Conclusion:Preoperative progressive neumoperitoneum is a recommended method in the management of patients with giant hernias and loss of domain, because it is low cost, safe and easy to perform and avoids the possible complications that the closure of the defect with tension entails

Incisional hernia after bariatric surgery: only the physical examination is enough? / Hérnia incisional após a cirurgia bariátrica: apenas o exame físico é suficiente?

ABSTRACT BACKGROUND: Incisional hernia is characterized by a bulging of the abdominal wall caused by the prolapse of intracavitary structures, such as a segment of the small intestine, through the trocar orifice. Ultrasonography and physical examination are used in the diagnosis of incisional hernia. AIMS: This study aimed to evaluate the difference between physical examination and abdominal ultrasonography at the diagnosis of incisional hernia in patients who underwent laparoscopic bariatric surgery. METHODS: A total of 123 patients who underwent Roux-en-Y gastric bypass type bariatric surgery performed by laparoscopy were analyzed for the presence or absence of hernia by physical and ultrasonography examination at each trocar incision site. RESULTS: In our results, a total of 7 hernias were detected by physical examination, while ultrasonography detected a total of 56 hernias in at least one of the incision sites. Lin's concordance analysis showed that the tests are not concordant. The association between body mass index and hernia detection (p=0.04 for physical examination and p=0.052 for ultrasonography) was observed. Ultrasonography detected more incisional hernias in 10-mm or larger trocars than in 5-mm trocars (p<0.0001, p<0.05). No differences were noted among the trocar types that were used. CONCLUSIONS: Abdominal ultrasonography showed to have a higher accuracy than physical examination, resulting in a substantial increase in incisional hernia detection at the trocar sites.

RESUMO RACIONAL: A hérnia incisional é caracterizada por um abaulamento da parede abdominal causada por um prolapso das estruturas intracavitárias, como um segmento do intestino delgado, através de um orifício de trocarte. A ultrassonografia e o exame físico são usados no diagnóstico da hérnia incisional. OBJETIVOS: Avaliar a diferença entre o exame físico e a ultrassonografia abdominal no diagnóstico da hérnia incisional em pacientes submetidos a cirurgia bariátrica por videolaparoscopia. MÉTODOS: O total de 123 pacientes submetidos à cirurgia bariátrica, tipo derivação gástrica em Y de Roux, foram avaliados para a presença ou ausência de hérnia incisional por exame físico e ultrassonografia, nos sítios incisionais de cada trocarte. RESULTADOS: O total de sete hérnias foram detectados por exame físico, enquanto a ultrassonografia detectou um total de 56 hérnias em pelo menos um sítio incisional. A análise de concordância de Lin mostrou que os testes empregados não são concordantes. A associação entre o Índice de Massa Corpórea e a detecção de hérnia foi observada (p=0.04, para exame físico, p=0.052 para ultrassonografia). A ultrassonografia detectou mais hérnias incisionais em trocartes de 10 mm ou mais do que em trocartes de 5 mm (p<0,0001, p<0.05). Não foi observada diferença entre os tipos de trocartes empregados. CONCLUSÕES: A ultrassonografia abdominal demonstrou ter acurácia mais elevada que o exame físico, resultando em um aumento substancial na detecção de hérnia incisional nos locais de inserção dos trocartes.

Early incisional hernia after liver transplantation: risk factors and hernia repair results / Hérnia incisional precoce após transplante hepático: fatores de risco e resultados do reparo cirúrgico

ABSTRACT BACKGROUND: Liver transplantation is a complex and valuable therapy. However, complications that burden postoperative quality of life, such as incisional hernia, are to be better elucidated, such as risk factors and prophylactic measures. AIM: This study aimed to define the rate of incisional hernia in patients who underwent liver transplantation in a population in southern Brazil and to assess the related risk factors in order to establish measures for prior optimization and specific prophylactic care in the future. METHODS: Patients undergoing adult Liver transplantation from January 2004 to November 2020 were retrospectively analyzed, assessing demographic features, surgical outcomes, and predisposing factors. RESULTS: Among 261 liver transplantation patients included, incisional hernia was diagnosed in 71 (27.2%). Of the 71 incisional hernia patients, 28 (39.4%) developed IH during the first post-transplant. Majority of the patients were male (52/71, 73.2%); of the 71 patients, 52 had hepatitis C virus (HCV) and 33 (46.5%) had hepatocellular carcinoma (HCC). Male gender (p=0.044), diabetes mellitus (p=0.008), and acute cellular rejection (p<0.001) were risk factors for IH. In all, 28 (39.4%) patients were submitted for hernia repair with mesh, with a recurrence rate of 17.8%. CONCLUSION: Incisional hernia after liver transplantation is a relatively common problem associated with male gender, diabetes, and acute cellular rejection. This is a problem that should not be trivialized in view of the complexity of liver transplantation, as it can lead to a reduction in quality of life as well as jeopardize late liver transplantation results and lead to incarceration and strangulation.

RESUMO RACIONAL: O transplante de fígado é uma terapia complexa e valiosa. Entretanto, complicações que prejudicam a qualidade de vida pós-operatória, como a hérnia incisional, devem ser mais bem elucidadas, analisando os fatores de risco e medidas profiláticas. OBJETIVOS: Definir a taxa de hérnia incisional em pacientes submetidos a transplante de fígado em uma população do sul do Brasil, avaliar os fatores de risco relacionados, a fim de estabelecer futuramente medidas de otimização prévia e cuidados profiláticos específicos. MÉTODOS: Foram analisados, retrospectivamente, pacientes submetidos a transplante de fígado adultos, de janeiro de 2004 a novembro de 2020, avaliando suas características demográficas, resultados cirúrgicos e fatores predisponentes. RESULTADOS: Dentre os 261 pacientes transplantados hepáticos incluídos, a hérnia incisional foi diagnosticada em 71 (27,2%). Vinte e oito do total de 71 pacientes com hérnia incisional (39,4%) desenvolveram hérnia incisional durante o primeiro ano pós-transplante. A maioria era do sexo masculino [n=52, (73,2%)]; 52/71 (73,2%) apresentavam cirrose secundária ao vírus da hepatite C; 33/72 (46,5%) foram portadores de carcinoma hepatocelular. Sexo masculino (p=0,044), diabetes mellitus (p=0,008) e rejeição celular aguda (p<0,001) foram fatores de risco estatisticamente significantes para hérnia incisional. Vinte e oito pacientes (39,4%) foram submetidos à hernioplastia incisional com tela, com taxa de recidiva de 17,8%. CONCLUSÕES: Hérnia incisional após transplante de fígado é um problema relativamente comum, associado ao sexo masculino, diabetes e também a rejeição celular aguda. Este é um problema que não deve ser banalizado, já que pode levar à redução da qualidade de vida, comprometer os resultados tardios do transplante de fígado e pode levar a encarceramento ou estrangulamento.
