RESUMO

OBJECTIVE: To develop a multidimensional method that allows to identify different treatment concepts, techniques, protagonists, and their connections in surgical pathology of the abdominal wall throughout its historical development, serving as a basis or guide for the future. METHOD: First, an extensive and rigorous review of the literature was conducted to search for and group the different treatments described in the most common abdominal wall pathologies, including both groin and ventral hernias. Then, all treatment approaches were chronologically ordered and grouped according to their author, surgical approach, and method of approach. With all the information gathered, a table was created following a rational and multidimensional criterion that allows for the encoding of the set. RESULTS: 21 treatment modalities were identified and distributed into 8 groups. Additionally, 3 types of authors were detected: the creator, the innovator, and the popularizer. The assignment of values to different dimensions allowed us to obtain an alphanumeric code representative of the set. CONCLUSION: Multidimensional historical analysis allows analytical objectivity and set encoding. Its practical scope should be investigated.

RESUMO

Introducción. Las hernias gigantes con pérdida de domicilio son aquellas cuyo saco herniario alcanza el punto medio del muslo en bipedestación y su contenido excede el volumen de la cavidad abdominal. Estas hernias son un reto quirúrgico dada la difícil reducción de su contenido y del cierre primario de la fascia. Tienen mayor riesgo de complicaciones asociadas al síndrome compartimental abdominal, así como mayor tasa de recurrencia y morbilidad en los pacientes. Caso clínico. Paciente masculino de 81 años, reconsultante por hernia inguinoescrotal derecha gigante, de dos años de evolución, sintomática, con índice de Tanaka de 24 %. Se decidió aplicar el protocolo de neumoperitoneo secuencial (hasta 11.000 ml en total en cavidad) además de toxina botulínica en pared abdominal (dos sesiones). Resultados. Se logró la corrección exitosa de la hernia inguinoescrotal gigante, sin recaídas de su patología abdomino-inguinal. El paciente manifestó satisfacción con el tratamiento un año después del procedimiento. Conclusiones. El protocolo de neumoperitoneo secuencial es una alternativa en casos de hernias complejas, con alto riesgo de complicaciones, que requieren técnicas reconstructivas adicionales. La aplicación previa de toxina botulínica es un adyuvante considerable para aumentar la probabilidad de resultados favorables. Sin embargo, debe incentivarse la investigación en esta área para evaluar su efectividad.

Introduction. Giant hernias with loss of domain are those whose hernial sac reaches the midpoint of the thigh in standing position and whose content exceeds the volume of the abdominal cavity. These hernias are a surgical challenge given the difficult reduction of their contents and the primary fascial closure, with a higher risk of complications associated with abdominal compartment syndrome, as well as a higher rate of recurrence and morbidity in patients. Clinical case. A 81-year-old male patient with comorbidity, reconsulting due to a symptomatic giant right inguinoscrotal hernia of two years of evolution, with a Tanaka index of 24%, eligible for a sequential pneumoperitoneum protocol (up to a total of 11,000 cc in cavity) plus application of botulinum toxin (two sessions) in the abdominal wall. Results. Successful correction of the patient's giant inguinoscrotal hernia was achieved using this protocol, without recurrence of his abdomino-inguinal pathology and satisfaction with the procedure after one year. Conclusion. The sequential pneumoperitoneum protocol continues to be an important alternative in cases with a high risk of complications that require additional reconstructive techniques, while the previous application of botulinum toxin is a considerable adjuvant to further increase the rate of favorable results. However, research in the area should be encouraged to reaffirm its effectiveness.

RESUMO

Purpose: To test the use of rainbow trout skin as a surgical mesh in abdominal hernioplasties in rats. Methods: The experiment involved 20 Wistar rats receiving implants of trout skin processed for disinfection in 0.5% glutaraldehyde and preserved in 100% glycerin. The animals were divided into four groups, divided at 7, 15, 30, and 90 days postoperatively. Clinical and infrared thermography evaluations were performed, and after euthanasia, assessments of adhesion formations and sample collection for histological evaluation were conducted. Results: The implant was observed to be intact, ensuring the integrity of the abdominal wall, support for the viscera, and normal mobility for the rats for up to 90 days. Low rates of clinical alterations were observed, with an intense inflammatory reaction up to day 7, chronic inflammation and the onset of angiogenesis at day 15, and a low inflammatory reaction with collagenous infiltrate and fibrosis at day 30. At day 90, the implants showed a collagenous and fibrotic infiltrate with a minimal inflammatory infiltrate. Conclusions: The surgical mesh of trout skin performed well, making it a potential alternative for surgical procedures in muscle aponeurotic corrections in the abdominal wall.

RESUMO

ABSTRACT BACKGROUND: Maintaining normal intra-abdominal pressure (IAP) levels must be one major outcome of any ventral hernia repair, avoiding hypertension or abdominal compartment syndrome. AIMS: To evaluate IAP during ventral hernia repair using Lázaro da Silva's procedure. METHODS: IAP measurements using intravesical pressure were performed during four crucial intraoperative moments. Twenty-eight patients submitted to incisional herniorrhaphy were analyzed. RESULTS: The IAP increased by 0.5 mmHg during the procedure, regardless of the type of prior laparotomy, sex, age, obesity, or hernia width. CONCLUSIONS: Despite the IAP increase observed, Lázaro da Silva's procedure did not result in intra-abdominal hypertension or abdominal compartment syndrome.

RESUMO RACIONAL: A manutenção dos níveis normais de pressão intra-abdominal (PIA) deve ser um dos principais resultados de qualquer correção de hérnia ventral, evitando hipertensão ou síndrome do compartimento abdominal. OBJETIVOS: Avaliar a PIA durante a correção de hérnia ventral pela técnica de Lázaro da Silva. MÉTODOS: As medidas da PIA por meio de pressão intravesical foram realizadas durante quatro momentos cruciais do intraoperatório. Foram analisados 28 pacientes submetidos à herniorrafia incisional. RESULTADOS: A PIA aumentou 0,5 mmHg durante o procedimento, independentemente do tipo de laparotomia prévia, sexo, idade, obesidade ou extensão da hérnia. CONCLUSÕES: Apesar do aumento da PIA observado, o procedimento de Lázaro da Silva não resultou em hipertensão intra-abdominal ou síndrome do compartimento abdominal.

RESUMO

Las hernias gigantes de Amyand son hernias inguinales excepcionales por extenderse por debajo de la mitad del muslo en posición de pie y contener al apéndice cecal. Presentamos un paciente portador de una hernia gigante de Amyand irreductible, al cual se le realiza una reparación quirúrgicas, mediante una combinada de técnicas para su resolución. El tratamiento de las hernias inguinales gigantes es todo un desafío, debido a la distorsión anatomía existente, y por la pérdida de derecho a domicilio de los órganos que puede llegar a ocasionar. Consideramos que la combinación de las técnicas de Bassini y Lichtennstein asociado a las maniobras de Ombrédanne y de Camay es una estrategia adecuada para reparar exitosamente las hernias inguinales gigantes grado I. La apendicectomía en la hernia de Amyand tipo I es una alternativa de tratamiento cuando existe riesgo de apendicitis aguda.

Giant Amyand hernias are exceptional inguinal hernias because they extend below the middle of the thigh in the standing position and contain the cecal appendix. We present a patient with an irreducible giant Amyand hernia, who underwent surgical repair, using a combination of techniques for its resolution. The treatment of giant inguinal hernias is quite a challenge, due to the existing anatomical distortion, and the loss of the right to domicile of the organs that it can cause. We consider that the combination of the Bassini and Lichtenstein techniques associated with the Ombrédanne and Camay maneuvers is an appropriate strategy to successfully repair grade I giant inguinal hernias. Appendectomy in Amyand type I hernia is a treatment alternative when a risk of acute appendicitis exists.

RESUMO

INTRODUCTION: Spigelian hernia is a rare entity, with higher improbability of acute appendicitis within it. CASE REPORT: A 75-year-old female with a 30-year evolution hernia, abdominal pain, and fever of 1 week of onset, in whom was found an acute appendicitis within a Spigelian hernia. DISCUSSION: Spigelian hernia comprises 0.12-2% of all abdominal hernias. Presurgical diagnosis is stablished only in 50% of cases, with an hernial ring less than 2 cm and hidden localization. There isn't statistics of this complication because of the lack of case reports.

RESUMO

BACKGROUND: Patients with abdominal site cancer are at risk for incisional hernia after open surgery. This study aimed to compare the short- and long-term outcomes of robotic-assisted (RVIHR) with the laparoscopic incisional hernia repair (LVIHR) in an oncologic institute. METHODS: This is a single-blinded randomized controlled pilot trial. Patients were randomized into two groups: RVIHR and LVIHR. RESULTS: Groups have similar baseline characteristics (LVIHR: N = 19; RVIHR: N = 18). No difference was noted in the length of hospital stay (RVIHR: 3.67 ± 1.78 days; LVIHR: 3.95 ± 2.66 days) and postoperative complications (16.7 versus 10.5%; p = 0.94). The mean operating time for RVIHR was significantly longer than LVIHR (RVIHR was 355.6 versus 293.5 min for LVIHR; p = 0.04). Recurrence was seen in three patients in LVIHR and two in RVIHR at 24-month follow-up, with no significant difference. (p > 0.99). CONCLUSION: Laparoscopic and robotic-assisted incisional hernia repair show similar short- and long-term outcomes for cancer patients.

RESUMO

ABSTRACT Introduction: Inguinal hernia and varicocele are common conditions in male population. Laparoscopy brings the opportunity to treat them simultaneously, through the same incision. However, there are different opinions about the risks for testicular perfusion of multiple procedures in the inguinal region. In this study, we assessed the feasibility of simultaneous laparoscopic procedures by studying clinical and surgical outcomes of patients undergoing bilateral inguinal hernioplasty using the transabdominal preperitoneal (TAPP) technique with and without concomitant bilateral laparoscopic varicocelectomy (VLB). Methods: a sample of 20 patients from the University Hospital of USP-SP with indirect inguinal hernia and varicocele with indication for surgical correction was selected. Patients were randomized into two groups, 10 undergoing TAPP (Group I) and 10 undergoing simultaneous TAPP and VLB (Group II). Data regarding total operative time, complications and postoperative pain was gathered and analyzed. Results: there was no statistical difference between groups regarding total operative time and postoperative pain. Only one complication (spermatic cord hematoma) was observed in Group I and no complications were observed in Group II. Conclusions: simultaneous TAPP and VLB in was shown to be effective and safe, which provides a basis for conducting studies on larger scales.

RESUMO Introdução: hérnia inguinal e varicocele são doenças comuns na população masculina. O advento da laparoscopia traz a oportunidade de tratá-las simultaneamente, pelo mesmo acesso. Entretanto, existem divergências sobre os riscos para a perfusão testicular de múltiplos procedimentos na região inguinal. Neste estudo, avaliamos a viabilidade de procedimentos laparoscópicos simultâneos estudando resultados clínicos e cirúrgicos de pacientes submetidos à hernioplastia inguinal bilateral pela técnica transabdominal préperitoneal (TAPP) com e sem varicocelectomia laparoscópica bilateral (VLB) concomitante. Métodos: uma amostra de 20 pacientes do Hospital Universitário da USP-SP com hérnia inguinal indireta e varicocele com indicação de correção cirúrgica foi selecionada. Os pacientes foram randomizados em dois grupos, sendo 10 submetidos à TAPP (Grupo I) e 10 submetidos à TAPP e VLB simultâneas (Grupo II). O tempo operatório total, complicações e dor pós-operatória foram coletados e analisados. Resultados: não houve diferença estatística entre os grupos com relação ao tempo operatório total e à dor pós-operatória. Apenas uma complicação (hematoma do cordão espermático) foi observada no Grupo I e não foram observadas complicações no Grupo II. Conclusões: no mesmo procedimento, submeter pacientes à TAPP e à VLB no mesmo procedimento se mostrou eficaz e seguro, o que fornece embasamento para a realização de estudos em maiores escalas.

RESUMO

ABSTRACT Introduction: it is estimated that approximately 20 million people undergo inguinal hernia surgery annually in the world, with the Lichtenstein technique being the most performed surgical procedure. The objective of this study is to analyze the knowledge of the technical principles used in the Lichtenstein technique. Method: Survey-type intersectional study approved by the research ethics committee of São Camilo University Center (CAAE: 70036523.1.0000.0062). During the research period, 11,622 e-mails were sent to members of the main national surgical societies with research on the technical principles of Lichtenstein surgery. The survey was carried out using an electronic form with 10 multiple-choice questions. The form was answered anonymously on the SurveyMonkey and Google Forms platforms. Result: 744 responses were received to the electronic form. Based on this number of respondents, our survey has a confidence level of 95% with a margin of error of 3.5%. It was observed that there is no standardization of the technique among the majority of responders (53.4%). Many surgeons still perform digital dissection of the spermatic cord (47%). A small number of interviewees (15.2%) performed sutures with absorbable thread in the region of the internal oblique aponeurosis, while more than half (55.2%) continued to perform sutures with non-absorbable thread. Most surgeons use a small overlap or fix the mesh juxtaposed to the pubic symphysis (51%). Conclusion: Our research identified that a small percentage of respondents adequately know the technical principles of Lichtenstein surgery. The result brings us new insights into the need to review Lichtenstein technique.

RESUMO Introdução: estima-se que aproximadamente 20 milhões de pessoas sejam submetidas a cirurgia de hérnia inguinal anualmente no mundo, sendo a técnica de Lichtenstein o procedimento cirúrgico mais realizado. O objetivo desse estudo é analisar o conhecimento dos principios técnicos empregados na técnica de Lichtenstein. Método: estudo tipo levantamento interseccional aprovado pelo comitê de ética em pesquisa do Centro Universitário São Camilo (CAAE: 70036523.1.0000.0062). Durante o período da pesquisa foram encaminhados 11.622 e-mails aos membros das principais sociedades cirúrgicas nacionais com uma pesquisa sobre os princípios técnicos da cirurgia de Lichtenstein. A pesquisa foi realizada por formulário eletrônico com 10 questões de múltipla escolha. O formulário foi respondido de forma anônima nas plataformas SurveyMonkey e Google Forms. Resultado: foram recebidos 744 respostas ao formulário eletrônico. Com base nesse número de respondedores, nossa pesquisa apresenta grau de confiança de 95% com margem de erro de 3,5%. Foi observado que não há padronização da técnica entre a maioria dos respondedores (53.4%). Muitos cirurgiões ainda fazem dissecção digital do funículo espermático (47%). Um pequeno número de entrevistados (15,2%) realizam sutura com fio absorvível na região da aponeurose do obliquo interno, enquanto, mais da metade (55,2%) continua fazendo sutura com fio inabsorvível. A maior parte dos cirurgiões utilizam overlap pequeno ou fixam a tela justaposta a sínfise púbica (51%). Conclusão: nossa pesquisa identificou que uma porcentagem pequena dos entrevistados conhecem adequadamente os princípios técnicos da cirurgia de Lichtenstein. O resultado nos traz novas percepções sob a necessidade de revistar a consagrada técnica de Lichtenstein.
