ABSTRACT

ABSTRACT Introduction: the botulinum toxin A (BTA) has been used to achieve a chemical component separation, and it has been used with favorable outcomes for the repair of complex ventral hernia (CVH) with and without loss of domain (LD). The aim of this study is to describe our early experience with the chemical component separation in the United Sates. Methods: a retrospective observational study of all patients who underwent ventral hernia repair for CVH with or without LD between July 2018 and June 2020. Preoperative BTA was injected in all patients via sonographic guidance bilaterally, between the lateral muscles to achieve chemical denervation before the operation. Patient demographics, anatomical location of the hernia, perioperative data and postoperative data are described. Results: 36 patients underwent this technique before their hernia repair between July 2018 to June 2020. Median age was 62 years (range 30-87). Median preoperative defect size was 12cm (range 6-25) and median intraoperative defect size was 13cm (range 5-27). Median preoperative hernia sac volume (HSV) was 1338cc (128-14040), median preoperative abdominal cavity volume (ACV) was 8784cc (5197-18289) and median volume ration (HSV/ACV) was 14%. The median OR time for BTA administration was 45 minutes (range 28-495). Seroma was the most common postoperative complication in 8 of the patients (22%). Median follow up was 43 days (range 0-580). Conclusion: preoperative chemical component separation with BTA is a safe and effective adjunct to hernia repair in CVH repairs where a challenging midline fascial approximation is anticipated.


RESUMO Introdução: a toxina botulínica A (TBA) tem sido usada para alcançar a separação química dos componentes, com resultados favoráveis para o reparo de hérnias ventrais complexas (HVC) com ou sem perda de domínio (PD). O objetivo deste estudo é descrever nossa experiência inicial com a separação química dos componentes nos Estados Unidos. Métodos: estudo retrospectivo observacional com todos os pacientes submetidos a reparo de hérnia ventral complexa com ou sem PD entre julho de 2018 e junho de 2020. A TBA pré-operatória foi injetada em todos os pacientes, guiada por ultrassonografia, bilateralmente entre os músculos laterais para alcançar a denervação química antes da operação. Dados demográficos dos pacientes, local da hérnia, dados peri-operatórios e pós-operatórios são descritos. Resultados: 36 pacientes foram submetidos a esta técnica antes do reparo da hérnia. A idade mediana foi 62 anos (30-87). O tamanho mediano pré-operatório do defeito herniário foi 12cm (6-25) e o defeito mediano intra-operatorio foi 13cm (5-27). O volume mediano do saco herniário pré-operatório foi 1.338mL (128-14.040), o volume mediano da cavidade abdominal pré-operatório foi 8.784 (5.197-18.289) mL e a razão dos volumes foi 14%. A duração mediana da operação para aplicação da TBA foi 45 minutos (28-495). O seroma foi a complicação mais comum no pós-operatório, em oito pacientes (22%). O seguimento pós-operatório mediano foi de 43 dias (0-580). Conclusão: a separação pré-operatória de componentes com TBA é tratamento adjuvante seguro e eficaz em reparos de HVC em que aproximação da fáscia é antecipadamente desafiadora.

ABSTRACT

Introducción. Los pacientes con inmunosupresión llevados a cirugía abdominal convencional tienen un mayor riesgo de desarrollar hernias incisionales en el posoperatorio, y cuando ellas ocurren, es necesario individualizar el procedimiento quirúrgico de elección, según las características anatómicas, fisiológicas y clínicas de cada paciente. Este estudio describe las características demográficas y clínicas de los pacientes con inmunosupresión, llevados a reconstrucción de la pared abdominal, y sus desenlaces después de 30 días del procedimiento quirúrgico. Métodos. Serie de casos de pacientes con inmunosupresión llevados a reconstrucción de la pared abdominal, en un centro especializado de cuarto nivel de complejidad. Se incluyeron pacientes mayores de 18 años, operados en el período de enero de 2016 a diciembre de 2019. Resultados. Se presenta una serie de 18 pacientes, cinco (27,7 %) con algún tipo de inmunosupresión primaria y 13 (72,2 %) con algún tipo de inmunosupresión secundaria. La edad promedio fue de 56 años, 11 (61 %) fueron mujeres, el peso promedio de los participantes fue de 73,3 kg. Se encontraron complicaciones en ocho pacientes (44,4 %). Dos pacientes requirieron manejo en la Unidad de Cuidados Intensivos, por un máximo de tres días. Ninguno de los pacientes presentó recidiva de la hernia ni mortalidad. Discusión. La reconstrucción de la pared abdominal en pacientes inmunosuprimidos representa un reto para cualquier equipo quirúrgico debido a las condiciones especiales de los pacientes y a las variables asociadas al procedimiento. Las tasas de recidiva y de complicaciones de este estudio, se asemejan a las descritas en la literatura


Introduction. Immunosuppressed patients undergoing conventional abdominal surgery have a higher risk of developing incisional hernias postoperatively, and when they do occur, it is necessary to individualize the surgical procedure of choice, according to the anatomical, physiological and clinical characteristics of each patient. This study describes the demographic and clinical characteristics of immunosuppressed patients, who underwent abdominal wall reconstruction and their outcomes 30 days after the surgical procedure.Methods. Series of cases of patients with immunosuppression underwent abdominal wall reconstruction in a specialized center of fourth level of complexity. Patients older than 18 years, operated on from January 2016 to December 2019, were included. Results. A series of 18 patients is analyzed, five (27.7%) with some type of primary immunosuppression and 13 (72.2%) with some type of secondary immunosuppression. The average age was 56 years, 11 (61%) were women, the average weight of the participants was 73.3 kg. Complications were found in eight patients (44.4%). Two patients required management in the ICU, for a maximum of three days. None of the patients had hernia recurrence or mortality. Discussion. Reconstruction of the abdominal wall in immunosuppressed patients represents a challenge for any surgical team due to the special conditions of the patients and the variables associated with the procedure. The recurrence and complication rates in this study are similar to those described in the literature.

ABSTRACT

Abstract Objective To investigate the effect of closure types of the anterior abdominal wall layers in cesarean section (CS) surgery on early postoperative findings. Methods The present study was designed as a prospective cross-sectional study and was conducted at a university hospital between October 2018 and February 2019. A total of 180 patients who underwent CS for various reasons were enrolled in the study. Each patient was randomly assigned to one of three groups: Both parietal peritoneum and rectus abdominis muscle left open (group 1), parietal peritoneum closure only (group 2), and closure of the parietal peritoneum and reapproximation of rectus muscle (group 3). All patients were compared in terms of postoperative pain scores (while lying down and duringmobilization), analgesia requirement, and return of bowel motility. Results The postoperative pain scores were similar at the 2nd, 6th, 12th, and 18th hours while lying down. During mobilization, the postoperative pain scores at 6 and 12 hours were significantly higher in group 2 than in group 3. Diclofenac use was significantly higher in patients in group 1 than in those in group 2. Meperidine requirements were similar among the groups. There was no difference between the groups' first flatus and stool passage times. Conclusion In the group with only parietal peritoneum closure, the pain scores at the 6th and 12th hours were higher. Rectus abdominismuscle reapproximations were found not to increase the pain score. The closure of the anterior abdominal wall had no effect on the return of bowel motility.

ABSTRACT

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

ABSTRACT

Resumen La falla en la reparación de los defectos de la pared abdominal se relaciona con una alteración en la integración del material protésico. El objetivo de este trabajo fue evaluar el comportamiento biológico de mallas utilizadas en cirugía de paredes abdominales en un modelo animal. Luego de la confección de un defecto parietal se colocó una malla intraperitoneal, utilizando 4 grupos de 10 ratas; 1) Prolene (polipropileno microporo de alto peso), 2) Ultrapro (polipropileno + poliglecaprone, macroporo de bajo peso), 3) Proceed (polipropileno + polidoxanona + celulosa oxidada regenerada, macroporo de peso intermedio), y 4) Physiomesh (polipropileno + poliglecaprone, macroporo de bajo peso). Se realizó análisis macroscópico y microscópico a los 30 días y los resultados fueron evaluados por dos observadores independientes. Al examen macroscópico, la integración de la prótesis fue > 75% en todos los grupos. El análisis microscópico mostró mayor inflamación global y número de células gigantes multinucleadas en Prolene (p < 0.01) y menor cantidad de células inflamatorias en la interface músculo-malla en Physiomesh < Ultrapro (p < 0.05). La organización de las fibras de colágeno fue similar para todas las mallas, aunque hubo mayor depósito de colágeno en los espacios inter-filamento para las mallas macroporosas (p < 0.01). Concluimos que las mallas de polipropileno microporo y alto peso producen mayor reacción inflamatoria y de cuerpo extraño. Por lo tanto, las mallas compuestas tendrían una mejor biocompatibilidad y serían mejor toleradas por el huésped.


Abstract An adequate integration of the prosthetic materials used to repair abdominal wall defects is necessary for satisfactory outcomes. We aimed to evaluate, in an animal model, the biological behavior of meshes used for abdominal wall surgery. Four groups of 10 rats were separated. After laparotomy, intraperitoneal prostheses were placed: 1) Prolene (polypropylene microporous, heavy-weight), 2) Ultrapro (polypropylene + poliglecaprone, macroporous low-weight), 3) Proceed (polypropylene + polidoxanone + regenerated oxidized cellulose, microporous medium-weight), 4) Physiomesh (polypropylene + poliglecaprone, macroporous lowweight). Macroscopic and microscopic analyses were performed at 30 days. The results were evaluated by two independent observers and expressed in means with standard deviation. For statistical analysis p < 0.05 was considered significant. On macroscopic examination, mesh integration was greater than 75% in all cases. Microscopic analysis showed greater global inflammation and more multinucleated giant cells in Prolene (p < 0.01). Less inflammatory cells were observed at the muscle-mesh interface in Physiomesh vs. Ultrapro (p < 0.05). Collagen fibers disposition was similar in all meshes, although, microporous meshes had higher collagen deposit in the interfilamentous spaces (p < 0.01). In conclusion, in our animal model, microporous and heavy-weight polypropylene meshes produce greater inflammatory and foreign body reaction. Thus, composite meshes would have greater biocompatibility and better tolerance by the host.

ABSTRACT

Inflammatory myofibroblastoma (IMT) is a rare solid tumor, and its etiology and pathogenesis are unclear. Crohn's disease is a non-specific intestinal inflammatory disease. The clinical manifestations, laboratory examinations, and imaging examinations of IMT are not specific, making diagnosis difficult. A case of Crohn's disease combined with IMT of abdominal wall was admitted to the Department of Gastroenterology at the Third Xiangya Hospital, Central South University, on Nov. 21, 2017. This patient was admitted to our hospital because of repeated right lower abdominal pain for 4 years. A 6 cm×5 cm mass was palpated in the right lower abdomen. After completing the transanal double-balloon enteroscopy and computed tomographic enterography for the small intestinal, the cause was still unidentified. The patient underwent surgery due to an abdominal wall mass with intestinal fistula on Sept. 12, 2018 and recovered well currently. According to histopathology and immunohistochemistry, he was diagnosed with Crohn's disease combined with IMT. Up to July 2020, the patients still took azathioprine regularly, without abdominal pain, abdominal distension, and other discomfort, and the quality of his life was good.

ABSTRACT

ABSTRACT Background: The use of polypropylene meshes for surgical repair of the abdominal wall contributes to a reduction of the of recurrence rates of hernias or defects. However, its intra-abdominal use comes along with the formation of adhesions and several complications. The study and the search for alternative materials, including bovine pericardium, have been regarded as an option for the correction and treatment of resulting hernias with better adaptations and effectiveness. Aim: Evaluating the inflammatory process of the bovine pericardium in comparison with the inflammatory process of synthetic polypropylene mesh. Method: Bovine pericardium mesh and polypropylene mesh were placed, both on the same animal. The first group had the mesh removed for analysis on day 20, and the second group on day 40. The variables congestion, granulation, giant cells, necrosis, acute inflammation, chronic inflammation and collagen were analyzed. Results: All variables were found in greater numbers as a response to the polypropylene mesh, except for the collagen, which, on day 40, was greater in response to the bovine pericardium mesh. Conclusion: The data in this study suggest that there is less inflammatory reaction in response to bovine pericardium mesh when compared to polypropylene mesh.


RESUMO Racional: O uso de telas de polipropileno para a correção cirúrgica da parede abdominal contribui para redução dos índices de recidiva das hérnias ou defeitos. No entanto, o seu uso intra-abdominal cursa com a formação de aderências e diversas complicações. O estudo e a busca por materiais alternativos, como pericárdio bovino, têm se mostrado uma opção na correção e tratamento de hérnias que resultem com melhores adaptações e efetividades. Objetivo: Avaliar o processo inflamatório do pericárdio bovino em comparação ao processo inflamatório da tela sintética de polipropileno. Método: Foi realizada a colocação de tela de pericárdio bovino e polipropileno, ambas no mesmo animal. O primeiro grupo as teve retiradas para análise no dia 20, e o segundo grupo no dia 40. Foram analisadas as variáveis congestão, granulação, células gigantes, necrose, inflamação aguda, inflamação crônica e colágeno. Resultados: Todas as variáveis foram encontradas em maior número como resposta a tela de polipropileno, exceto a variável colágeno, que no dia 40 apresentou-se em maior quantidade em resposta à tela de pericárdio bovino. Conclusão: Há menor reação inflamatória em resposta a tela de pericárdio bovino, quando comparada com a de polipropileno.

ABSTRACT

ABSTRACT Background: In the definition of the mesh to be used to correct hernias, porosity, amount of absorbable material and polypropylene should be considered in the different stages of healing process. Aim: To evaluate the inflammatory reaction in the use of macro and microporous meshes of high and low weight in the repair of defects in the abdominal wall of rats. Methods: Ninety Wistar rats (Rattus norvegicus albinus) were used. The animals were submitted to similar surgical procedures, with lesion of the ventral abdominal wall, maintaining the integrity of the parietal peritoneum and correction using the studied meshes (Prolene®, Ultrapro® and Bard Soft®). Euthanasia was performed at 30, 60 and 120 days after surgery. The abdominal wall segments were submitted to histological analysis using H&E, Masson's trichrome, immunohistochemistry, picrosirius red and tensiometric evaluation. Results: On the 120th day, the tensiometric analysis was superior with Ultrapro® macroporous mesh. The inflammatory process score showed a significant prevalence of subacute process at the beginning and at the end of the study. Microporous meshes showed block encapsulation and in macroporous predominance of filamentous encapsulation. Conclusion: The Ultrapro® mesh showed better performance than the others in healing process of the abdominal wall.


RESUMO Racional: Na definição da tela a ser utilizada na correção das hérnias deve-se considerar a porosidade, quantidade de material absorvível e polipropileno ou inabsorvível nas diversas fases da cicatrização. Objetivo: Avaliar a reação inflamatória das telas macro e microporosas de alta e baixa gramatura no reparo de defeito da parede abdominal de ratos. Método: Foram utilizados 90 ratos da raça Wistar (Rattus norvegicus albinus). Os animais foram submetidos a procedimentos cirúrgicos semelhantes, com lesão da parede abdominal ventral, mantendo a integridade do peritônio parietal e correção utilizando as telas Prolene®, Ultrapro® e Bard Soft®. Realizou-se a eutanásia aos 30, 60 e 120 dias de pós-operatório. Os segmentos da parede abdominal foram submetidos à análise histológica com H&E, tricômio de Masson, imunoistoquímica, picrosirius red e análise tensiométrica. Resultado: No 120º dia a análise tensiométrica mostrou superioridade da tela macroporosa Ultrapro®. O escore do processo inflamatório demonstrou prevalência significativa de processo subagudo no início e no final do estudo. As telas microporosas mostraram encapsulamento em bloco e as macroporosas encapsulamento predominantemente filamentar. Conclusão: A tela Ultrapro® mostrou melhor desempenho em relação às demais na cicatrização da parede abdominal.

ABSTRACT

ABSTRACT Introduction: currently, there are several clinical applications for robot-assisted surgery and in the hernia scenario, robot-assisted surgery seems to have the ability to overcome laparoscopic ventral hernias repairs limitations, facilitating dissection, defect closure, and mesh positioning. Exponentially grown in numbers of robotic approaches have been seen and even more complex and initially not suitable cases have recently become eligible for it. An appropriate tension-free reestablishment of the linea alba is still a major concern in hernia surgery and even with the robotic platform, dissecting and suturing in anterior abdominal wall may be challenging. This article reports a technical image artifice during a da vinci Xi-platform robotic ventral hernia repair allowing the surgeon to establish a more familiar and ergonomic manner to perform dissection and suturing in anterior abdominal wall. Technical Report: a step by step guided technique of image inversion artifice is described using detailed commands and figures to assure optimal surgical field and ergonomics whenever acting in robotic ventral hernias repair with the da Vinci Xi-platform. Our group brief experience is also reported, showing an easy and reproducible feature among surgeons with safe outcomes. Conclusion: we consider that image inversion artifice is a simple and reproducible feature in robotic ventral hernia repair. Through a step-by-step guide, this report enables the creation of an artifice providing a comfortable operative field and allowing the surgeon to achieve its best proficiency in hernia surgery.


RESUMO Introdução: as qualidades da cirurgia robótica em diversos campos da cirurgia minimamente invasiva são notórias e, no cenário de hérnias abdominais, ela tem se mostrado capaz de superar as limitações da laparoscopia facilitando a dissecção, o fechamento do defeito herniário e o posicionamento da tela. O número de abordagens robóticas cresceu exponencialmente e casos ainda mais complexos e inicialmente inadequados tornaram-se recentemente elegíveis para uma cirurgia menos invasiva. A reconstrução adequada da linha alba e livre de tensão ainda é uma grande preocupação na cirurgia de hérnia e, mesmo com a plataforma robótica, dissecar e suturar na parede abdominal anterior pode ser um desafio. Este artigo relata um artifício técnico com inversão de imagem durante a correção de hérnia ventral robótica com a plataforma Da vinci Xi, permitindo ao cirurgião estabelecer uma maneira mais familiar e ergonômica de realizar dissecção e sutura na parede abdominal anterior. Nota Técnica: uma técnica guiada passo a passo com artifício de inversão de imagem é descrita usando comandos e figuras detalhadas para garantir campo cirúrgico ideal e melhor ergonomia ao cirurgião sempre que atuar na correção de hérnias ventrais robóticas com a plataforma Da vinci Xi. Nossa breve experiência de grupo também é relatada, mostrando-se uma técnica fácil e reprodutível entre cirurgiões com resultados seguros. Conclusão: consideramos que o artifício de inversão de imagens é uma característica simples e reprodutível na correção de hérnia ventral robótica. Por meio de um guia passo a passo, este artigo detalha a criação de um artifício técnico que proporciona um campo operatório confortável ao cirurgião atingindo sua melhor proficiência em cirurgia de hérnia.

ABSTRACT

The practice of regional anesthesia is in a state of progressive evolution, mainly due to the advent of ultrasound as an anesthesiologist's instrument. Alternative techniques for postoperative analgesia of abdominal surgeries, such as transversus abdominis plane block, oblique subcostal transversus abdominis plane block, rectus abdominis muscle sheath block, ilioinguinal and iliohypogastric nerve block, and quadratus lumborum plane block, have proven useful, with good analgesic efficacy, especially when neuroaxial techniques (spinal anesthesia or epidural anesthesia) are not possible. This review discusses such blockades in detail, including the anatomical principles, indications, techniques, and potential complications.

ABSTRACT

Introducción: Las úlceras de Marjolin son neoplasias cutáneas que asientan sobre pieles afectadas por úlceras crónicas, quemaduras, cicatrices, estasis venosa o heridas cutáneas. Generalmente se diagnostica por medio de biopsias, siendo los carcinomas escamosos la variedad más frecuente. Existe escasa información sobre su desarrollo en heridas quirúrgicas abdominales previas, y aún menos casos reportados de su aparición sobre un defecto de la pared abdominal. Objetivo: Reporte de un caso de un paciente con antecedente de múltiples cirugías abdominales que desarrolló un carcinoma escamoso sobre cicatriz de laparotomía previa. Pacientes y Métodos: Presentación de un de un paciente masculino de 61 años, con antecedente de laparotomía exploradora, que consultó por una tumoración, de 6 meses de evolución, vegetante sobre eventración de mediana suprainfraumbilical. Se realiza exéresis de lesión en bloque de pared con enterectomia, anastomosis primaria y eventroplastia con malla de reemplazo. Cursa internación prolongada y con mala evolución, falleciendo al 77 día postoperatorio. Conclusión: Los carcinomas de células escamosas que se desarrollan sobre lesiones cutáneas previas presentan una agresividad mayor a aquellos desarrollados espontáneamente, tienen alto porcentaje de recidiva y metástasis asociadas. Se propone abordajes quirúrgicos radicales para su tratamiento, aun asi presentando una morbimortalidad elevada


Background: Marjolin ulcers are skin malignancies that appear on skin affected by chronic ulcers, burns, scars, venous stasis or skin wounds. They are generally diagnosed through a biopsy and the most frequent type is the squamous cell carcinoma. There is little information on its development in existing abdominal surgical wounds, and there are even fewer cases reported in relation to its appearance upon an abdominal wall defect. Objective: To report a case of a patient with a history of multiple abdominal surgeries who developed a squamous cell carcinoma in an existing laparotomy scar in association with an incisional hernia. Patient and Methods: A 61-year-old male patient, with history of an exploratory laparotomy in 1986, presents with a 6-month-old vegetating tumor upon a supra-infraumbilical median eventration. An excision of the lesion that included the abdominal wall and an associated enterectomy, primary anastomosis, and eventroplasty with replacement mesh was performed. During his prolonged hospital stay, he underwent with many medical intercurrences and even an additional surgery was needed. Eventually, the patient dies 77 days after the surgery. Conclusion: Squamous cell carcinomas that develop in existing skin lesions tend to be more aggressive than those that develop spontaneously. They have a high percentage of recurrence and associated metastases. Radical surgical approaches are suggested for its treatment, although it has a high morbidity and mortality rate.

Resumen Introducción: el dolor abdominal crónico es frecuente en consulta externa. El enfoque tradicional es investigar patologías viscerales. El 50 % de esos pacientes finalmente tiene dolor crónico de la pared abdominal (DCPA), generalmente secundario a atrapamiento del nervio cutáneo anterior. Esta entidad se identifica con el signo de Carnett. El tratamiento de elección es infiltrar con lidocaína los puntos dolorosos. Con una postinfiltración hay una mejoría significativa en el 85 %-90 % de los pacientes. Se desconoce la duración de la mejoría postinfiltración. El objetivo de este trabajo es determinar la respuesta sostenida en seguimientos a 1 y 2 años. Materiales y métodos: estudio de cohorte, retrospectivo, realizado en la unidad de gastroenterología de la Clínica Fundadores. Se incluyeron pacientes adultos mayores de 18 años que hubieran recibido tratamiento con inyección local con lidocaína al 2 % sin epinefrina y que hubieran respondido una encuesta telefónica para evaluar la intensidad del dolor en una escala análoga. Resultados: se identificaron 360 elegibles y, finalmente, atendieron la entrevista telefónica 324 pacientes (90 %). El 87 % era de sexo femenino. La edad promedio de la población era de 57 años. En la preinfiltración el dolor promedio era 8,7 puntos. En la postinfiltración los pacientes tuvieron una mejoría con una intensidad promedio de 2,38 (p < 0,05). En el 71 % de los pacientes la intensidad del dolor en el seguimiento hasta 2 años tuvo una intensidad promedio de 1,65 (p < 0,05), que representa una mejoría del 81 % en la intensidad (p = 0,001). La fibromialgia tuvo una asociación positiva con la mejoría sostenida del dolor (p = 0,008). Conclusiones: en los pacientes con DCPA, la infiltración de la pared con anestesia local produce una respuesta sostenida hasta 2 años después del tratamiento.


Abstract Introduction: Chronic abdominal pain is frequently encountered at outpatient clinics where the traditional approach is to investigate visceral pathologies. Fifty percent of these patients are finally found to have abdominal wall pain which is generally secondary to entrapment of the anterior cutaneous nerve. This entity is identified by Carnett's sign. The treatment of choice is to infiltrate the painful points with lidocaine following which there is significant improvement in 85% to 90% of these patients. The duration of post-infiltration improvement is unknown. The objective of this work is to determine sustained response in one and two-year follow-up examinations. Materials and Methods: This is a retrospective cohort study conducted in the gastroenterology unit of the Clínica Fundadores. We included adult patients over 18 years of age who had received local injection treatment with 2% lidocaine without epinephrine and who had answered a telephone survey to assess the intensity of pain on an analogous scale. Results: Of the 360 eligible patients identified, 324 patients (90%) were interviewed by telephone. The average age of those interviewed was 57 years, and 87% were women. The average pain level prior to infiltration was 8.7 points. Following infiltration, the average intensity was 2.38 points (p <0.05). In 71% of patients, average pain intensity at a two year follow-up examination was 1.65 points (p <0.05), an 81% improvement in intensity (p = 0.001). Fibromyalgia had a positive association with sustained improvement in pain (p = 0.008). Conclusions: Infiltration of the abdominal wall with a local anesthetic produces a sustained response for up to two years in patients with chronic abdominal wall pain.

ABSTRACT

RESUMEN La migración de malla en el posoperatorio alejado de la eventroplastìa y su consecuente infección es una complicación poco frecuente y peligrosa. La malla migrada genera reacción inflamatoria de tipo cuerpo extraño. Puede causar obstrucción intestinal, perforación intestinal o dolor abdominal cróni co. Solo se informan 4 casos en la literatura mundial de migración y uno con compromiso intestinal. Presentamos el caso de un tumor inflamatorio adherido a la pared abdominal, con contenido de poli propileno. El objetivo de esta carta científica es presentar una complicación poco habitual, destacando los aspectos más importantes de su manejo, definiendo algunas recomendaciones y remarcando la importancia del abordaje multidisciplinario.


ABSTRACT Mesh migration with subsequent infection years after incisional hernia repair is an uncommon and dangerous complication. Mesh migration produces an inflammatory foreign body reaction and can cause bowel obstruction, bowel perforation or chronic abdominal pain. Only four cases have been reported in the international literature, one of them with bowel involvement. We report a case of an inflammatory tumor containing polypropylene traces adhered to the abdominal wall. The aim of this scientific letter is to report a rare complication, emphasizing the most relevant aspects about its ma nagement, recommendations, and the relevance of a multidisciplinary approach.

ABSTRACT

RESUMEN La gastroquisis, es un defecto congénito de cierre de la pared abdominal, en general justa a la derecha de la insertación normal del cordón umbilical en la pared del abdomen. Rara vez ocupa una posición especular a la izquierda del cordón umbilical; una cantidad variable de intestinos, y en ocasiones otros órganos abdominales se hernian, fuera de la pared abdominal, sin saco ni cobertura membranosa a diferencia del onfalocele. El Proceso de Atención de Enfermería, es el método científico de actuación de los profesionales de la Enfermería, vinculados a una base teórica que desarrollan habilidades analíticas que aplicadas en la práctica, repercuten en la mejoría de los pacientes. El objetivo de este trabajo es describir un caso poco frecuente de gastroquisis, y vincularlo al proceso de atención de Enfermería. Se trató de una recién nacida, sexo femenino, raza mestiza. Ingresó en la Sala de Terapia Intensiva del Hospital Pediátrico Provincial Eliseo Noel Caamaño de Matanzas con 5 horas de nacida. La vinculación de este caso con el Proceso de Atención de Enfermería permitió una atención integral al individuo enfermo, y desarrolló las habilidades prácticas de la asistencia de enfermería (AU).


ABSTRACT Gastrochisis is a congenital defect of the abdominal wall closure, generally just on the right of the umbilical cord normal insertion in the abdominal wall. It rarely occupies a specular position to the right of the umbilical cord; a variable amount of intestines, and sometimes other abdominal organs, are herniated outside the abdominal wall, without a sac or a membranous covering unlike the omphalocele. The nursing care process is a scientific method of nursing professionals behavior, on a theoretical basis, developing analytical skills that, applied in the practice, have repercussion on the patients´ improvement. Describing an infrequent case of gastrochisis, and linking it to the Nursing care process is the aim of this article. The patient was a mestizo female newborn who entered the Intensive Care Ward of the Pediatric Provincial Hospital "Eliseo Noel Caamaño" of Matanzas five hours after birth. Linking this case to the Nursing care process allowed the integral care of the sick person, and developed the nursing care practical skills (AU).

ABSTRACT

Endobiliary radiofrequency ablation (RFA) is a procedure performed widely to induce locoregional tumor control by the transfer of thermal energy to the lesion and subsequent tumor necrosis. A 72-year-old male with a prior history of acute calculous cholangitis and perforated cholecystitis was admitted to the Kyungpook National University Hospital complaining of fever and nausea. He had an indwelling percutaneous transhepatic gallbladder drainage (PTGBD) catheter from the previous episode of perforated cholecystitis. An abdominal CT scan showed marked dilation of both the intrahepatic and extrahepatic bile ducts. Common bile duct cancer was confirmed histologically after an endobiliary biopsy. A surgical resection was considered to be the initial treatment option. During open surgery, multiple metastatic nodules were present in the small bowel mesentery and anterior abdominal wall. Resection of the tumor was not feasible, so endobiliary RFA was performed prior to biliary stenting. Cholecystectomy was required for the removal of the PTGBD catheter, but the surgical procedure could not be performed due to a cystic ductal invasion of the tumor. Instead, chemical ablation of the gallbladder (GB) with pure ethanol was performed to breakdown the GB mucosa. Palliative treatment for a biliary obstruction was achieved successfully using these procedures. In addition, a PTGBD catheter was removed successfully without significant side effects. As a result, an improvement in the patient's quality of life was accomplished.

ABSTRACT

ABSTRACT Objective: to study the characteristics of women undergoing abdominal surgery with suspected abdominal wall endometriosis or abdominal wall tumor, and to assess the association with age, race and previous cesarean delivery. Method: retrospective and analytical study carried out from January 2000 to December 2019, at the General Surgery Service of Hospital Universitário Antônio Pedro (HUAP) at Universidade Federal Fluminense (UFF). Medical records of 100 patients with abdominal wall endometriosis and other types of abdominal wall tumors were analyzed. Age, color, previous history of cesarean section or abdominal surgery and histopathological data were verified. The patients were classified as young adults (aged between 18 and 28 years and 11 months) and adults. The SPSS program was used for data analysis, Fisher's test with a significance level of 0.05. Results: abdominal wall endometriosis with histopathological confirmation was found in 22%, the mean age was 52.28 ± 18.66 which was lower when compared to other diagnoses. There was an association between previous cesarean section and abdominal wall endometriosis (p <0.005). Conclusion: the women with a diagnosis of abdominal wall endometriosis had undergone previous cesareans (the majority) and were in an active reproductive age. Although the brown skin women were the most frequent, there was no statistical difference.


RESUMO Objetivo: estudar o perfil das mulheres submetidas a cirurgia abdominal com suspeita de endometriose de parede abdominal ou tumor de parede abdominal e analisar a associação com a faixa etária, cor e cesariana prévia. Métodos: estudo retrospectivo e analítico realizado no período de janeiro de 2000 a dezembro de 2019, no Serviço de Cirurgia Geral do Hospital Universitário Antônio Pedro (HUAP) da Universidade Federal Fluminense (UFF). Analisaram-se prontuários de 100 pacientes com endometriose de parede abdominal e com outros tipos de tumoração de parede abdominal. Idade, cor, histórico prévio de cesariana ou cirurgia abdominal e resultado histopatológico foram avaliados. As pacientes foram classificadas em adultas jovem (idade entre 18 e 28 anos e 11 meses) e adultas. Utilizou-se para a análise dos dados o programa SPSS e, teste de Fisher com nível de significância de 0,05. Resultados: Endometriose de parede abdominal com confirmação histopatológica foi encontrada em 22% dos casos. A média de idade foi 52.28 ±18,66, menor quando comparada a outros diagnósticos. Observou-se associação entre cesariana prévia e endometriose de parede abdominal (p<0,005). Conclusão: as mulheres atendidas pelo Setor de Cirurgia da UFF com diagnóstico de endometriose de parede abdominal, na maioria, realizaram cesariana prévia e estavam em idade ativa, reprodutiva. Apesar da cor parda ter sido mais frequente, não se observou diferença estatística.
