Estudio comparativo de herniorrafía en emergencia y en situaciones electivas / Comparison study of herniorrhaphy at emergency and elective situations

La hernia inguinal es uno de los problemas urgentes más comunes encontrados por los cirujanos. Hubo 145 pacientes tratados debido al diagnóstico de hernia inguinal. De 44 pacientes que fueron operados en condiciones de emergencia. Alrededor de 131 casos (106 hombres y 25 mujeres) fueron tratados con reparación de malla preperitoneal abierta unilateral. Los pacientes fueron examinados en términos de complicaciones postoperatorias. Los datos recopilados incluidos como edad, sexo, historial médico, afecciones de cirugía, encarcelamiento y estrangulamiento. Hubo un total de 145 pacientes incluidos en el estudio; en el que 44 de ellos (29 hombres y 15 mujeres, rango de edad: 30-72) (Grupo I) fueron operados en condiciones de emergencia y 101 de ellas (51 hombres y 50 mujeres, rango de edad: 25-78) (grupo Ii) fueron operados en condiciones electivas. Hubo comorbilidad en 31 pacientes de grupo I y 77 pacientes del grupo II. Alrededor del 47.7% (n = 21) de los casos que se sometieron a cirugía emergente debido al encarcelamiento, mientras que el 43.6% (n = 44) de los casos que fueron operados en condiciones electivas. Había 12 hernias femorales en el Grupo I y 19 Hernia femoral en el Grupo II. No hay diferencia entre la complicación postoperatoria y las tasas de recurrencia en los casos de hernia inguinal operados en condiciones electivas y en condiciones de emergencia. Es más barato que la reparación laparoscópica, el control del dolor de plomo y la falta de dolor neuropático, tiene complicaciones menos testiculares, y es más ventajoso que otros enfoques abiertos

Inguinal hernia is one of the most common urgent problems encountered by surgeons. There were 145 patients treated due to inguinal hernia diagnosis. Out of 44 patients who were operated under emergency conditions. About 131 cases (106 male and 25 female) were treated with unilateral open preperitoneal mesh repair. Patients were examined in terms of postoperative complications. Data collected included as age, gender, medical history, surgery conditions, incarceration and strangulation. There were total of 145 patients included in the study; in which 44 of them (29 male and 15 female, range of age: 30- 72) (group I) were operated under emergency conditions and 101 of them (51 male and 50 female, range of age: 25-78) (group II) were operated under elective conditions. There was comorbidity in 31 patients of group I and 77 patients of group II. About 47.7% (n=21) of cases who underwent emergent surgery due to incarceration, while 43.6% (n=44) of cases who were operated under elective conditions. There were 12 femoral hernias in group I and 19 femoral hernia in group II. There is no difference between postoperative complication and recurrence rates in inguinal hernia cases operated under elective conditions and under emergency conditions. It is cheaper than laparoscopic repair, lead pain control and lack of neuropathic pain, has less testicular complications, and it is more advantageous than other open approaches.

Comparison of modified laparoscopic total extraperitoneal hernia repair and laparoscopic transabdominal preperitoneal hernia repair in patients with inguinal hernia / 中国医师进修杂志

Objective:To explore the application effects of modified laparoscopic total extraperitoneal hernia repair (TEP) and laparoscopic transabdominal preperitoneal hernia repair (TAPP) in inguinal hernia.Methods:One hundred and twenty-five patients with inguinal hernia in Yiwu Central Hospital from February 2017 to December 2019 were selected for retrospective study. They were divided into modified TEP group (63 cases) and TAPP group (62 cases). The modified TEP group was treated with modified TEP, and the TAPP group was treated with TAPP. The perioperative operation related indexes, serum oxidative stress indexes, 1-year recurrence rate and semen quality indexes were compared between the two groups.Results:The scores of visual analogue scale after operation for 24 h in the modified TEP group was lower than that in the TAPP group: (1.68 ± 0.39) scores vs. (1.97 ± 0.46) scores, P<0.05. After operation for 3 d, the levels of serum superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) in the modified TEP group were higher than those in the TAPP group: (92.79 ± 8.82) μmol/L vs. (84.40 ± 7.36) μmol/L, (81.52 ± 9.37) U/L vs. (75.75 ± 8.50) U/L; and the level of malondialdehyde (MDA) in the modified TEP group was lower than that in the TAPP group: (23.42 ± 3.3) μmol/L vs. (26.71 ± 3.92) μmol/L; the differences were statistically significant ( P<0.05). There was no significant difference in 1-year recurrence rate between the two groups ( P>0.05). One year after operation, the levels of acid phosphatase (ACP), fructose (FRU) and α- glucosidase (α- Glu) in the modified TEP group were higher than those in the TAPP group: (180.87 ± 20.15) kU/L vs. (159.85 ± 14.50) kU/L, (3.37 ± 0.84) g/L vs.(2.53 ± 0.67) g/L, (62.94 ± 6.25) kU/L vs. (43.96 ± 5.31) kU/L, the differences were statistically significant ( P<0.05). Conclusions:Both modified TEP and TAPP are effective methods for the treatment of inguinal hernia, but the former can reduce surgical trauma, recover quickly, and protect normal reproductive function.

The Lichtenstein technique is being used adequately in inguinal hernia repair: national analysis and review of the surgical technique / A técnica de Lichtenstein está sendo utilizada adequadamente nos reparos das hérnias inguinais: análise nacional e revisão da técnica cirúrgica

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.

Qual a melhor técnica de fixação da tela na cirurgia laparoscópica da hérnia inguinal? / What is the best mesh fixation technique in laparoscopic inguinal hernia surgery?

Introdução: As operações laparoscópicas têm aumentado anualmente, bem como os casos de prevalência das hérnias da parede abdominal. Com isso, as técnicas de se realizar as operações, bem como certos procedimentos vem sendo estudados. Uma das questões debatidas é a respeito do tipo de fixação da tela. Objetivo: Avaliar as técnicas de fixação da tela na cirurgia laparoscópica ventral da hérnia inguinal. Método: Trata-se de um estudo de revisão sistemática. Três bases de dados foram consultadas: Cochrane Database of Systematic Reviews (CDSR), EMBASE e PUBMED. Durante as buscas foram utilizados descritores com vocabulário controlado e text words. Resultados: Em relação ao desenho do estudo 1 revisão incluiu apenas ECA, 2 ECA e ECNA e 1 combinou a inclusão de ECA e estudos observacionais. Em relação ao tipo de fixação 2 estudos compararam os efeitos da fixação por tacha vs. cola de fibrina e outros 2 a comparação da fixação do grampo vs. cola de fibrina. De todos os desfechos de metanálise avaliados, apenas a redução da dor inguinal crônica pela fixação por cola de fibrina foi estatisticamente superior ao método de fixação mecânico em 3 dos 4 estudos. Conclusão: Os achados mostram que a diferença entre as técnicas de fixação da tela na cirurgia laparoscópica ventral da hérnia inguinal é que a fixação por cola diminui a incidência de dor crônica pós-operatória.

Introduction: Laparoscopic operations have increased annually, as well as the prevalence of abdominal wall hernias. With this, the techniques of performing the operations, as well as certain procedures, have been studied. One of the debated questions is about the type of fixation of the mesh. Objective: To evaluate mesh fixation techniques in ventral laparoscopic surgery for inguinal hernia. Method: This is a systematic review. Three databases were consulted: Cochrane Database of Systematic Reviews (CDSR), EMBASE and PUBMED. During the searches, descriptors with controlled vocabulary and text words were used. Results: Regarding the study design, 1 review included only ACE, 2 ACE and ECNA and 1 combined the inclusion of ACE and observational studies. Regarding the type of fixation, 2 studies compared the effects of stud fixation vs. fibrin glue and 2 others comparison of staple vs. fibrin glue. Of all the meta-analysis outcomes evaluated, only the reduction of chronic groin pain by fibrin glue fixation was statistically superior to the mechanical fixation method in 3 of 4 studies. Conclusion: The findings show that the difference between mesh fixation techniques in laparoscopic ventral inguinal hernia surgery is that glue fixation decreases the incidence of postoperative chronic pain.

Urgency hospitalizations for inguinal hernia in brazil from 2010 to 2019: mortality and costs in the public health system / Hospitalizações de urgência para hérnias inguinais no brasil de 2010 a 2019: mortalidade e custos no sistema único de saúde (sus)

ABSTRACT BACKGROUND: It is known that elective inguinal hernioplasties are safe procedures, but in an emergency setting, they have higher rates of complications and hospital costs. Despite this, quantitative studies on the subject in Brazil are still scarce. AIMS: To evaluate the trend in hospitalization rates, hospital mortality, and costs for inguinal hernia in an emergency, regarding gender and age group. METHODS: This is a time series study with data from the Unified Health System (SUS), at the national level, from 2010 to 2019. RESULTS: The overall hospitalization rate (p=0.007; b<0,02) in all age groups (p<0.005; b<0) in both genders indicated a decreasing trend. The general mortality rate in both genders and in most age groups showed an increasing trend (p<0.005), as well as the cost of hospitalization in all age groups of both genders. CONCLUSIONS: Urgent hospitalization rates for inguinal hernia in Brazil have shown a steady or decreasing trend; however, hospital mortality and costs per hospitalization have demonstrated an increasing trend in recent years.

RESUMO RACIONAL: Sabe-se que as hernioplastias inguinais eletivas são procedimentos seguros, mas que, em caráter de urgência, têm maiores taxas de complicações e custos hospitalares. Apesar disso, ainda são escassos os estudos quantitativos sobre o tema no Brasil. OBJETIVOS: Avaliar a tendência das taxas de internação, mortalidade hospitalar e custos por hérnia inguinal em caráter de urgência, quanto ao sexo e faixa etária. MÉTODOS: Trata-se de um estudo de séries temporais com dados do Sistema Único de Saúde (SUS), em nível nacional, no período de 2010 a 2019. RESULTADOS: A taxa de internação geral (p=0,007; b<0,02) em todas as faixas etárias (p<0,005; b<0) nos dois sexos indicou tendência decrescente. A taxa de mortalidade geral em ambos os sexos e na maioria das faixas etárias apresentou tendência crescente (p<0,005), assim como o custo da internação em todas as faixas etárias de ambos os sexos. CONCLUSÕES: As taxas de internação em caráter de urgência por hérnia inguinal, no Brasil, apresentaram tendência estacionária ou decrescente, entretanto, a mortalidade hospitalar e os custos por internação mostraram tendência crescente nos últimos anos.

Bilateral inguinal transabdominal pre-peritoneal laparoscopic hernioplasty associated to bilateral laparoscopic varicocelectomy in the same intervention: a feasibility study / Hernioplastia inguinal pré-peritoneal transabdominal bilateral e varicocelectomia laparoscópica bilateral na mesma intervenção: um estudo de viabilidade

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.

La hernia inguinal indirecta (HHI) es la anomalía congénita más frecuente en la infancia y niñez. En las niñas, las HII deslizantes contienen principalmente el ovario con o sin trompa de Falopio. Presentamos el caso de una niña de 6 meses, que acude por tumoración inguinal izquierda, irreductible, asociada a vómitos. Es intervenida de emergencia con diagnóstico de hernia inguinal indirecta izquierda complicada, conteniendo trompa de Falopio y ovario izquierdo gangrenados. Este tipo de hernia tiene una incidencia más alta en prematuros y de sexo femenino menores de un año. La ecografía preoperatoria puede ser útil para el diagnóstico. El procedimiento para la reparación es la herniorrafia clásica con ligadura alta del saco herniario, a través de un abordaje inguinal.

Indirect inguinal hernia (IHH) is the most frequent congenital anomaly in infancy and childhood. In girls, the sliding IIHs contain mainly the ovary with or without a fallopian tube. We present the case of a 6-month-old girl who was presented with an irreducible left inguinal tumor associated with vomiting. She was operated of emergency with a diagnosis of complicated left indirect inguinal hernia containing gangrenous fallopian tube and left ovary. This type of hernia has a higher incidence in prematures and females under one year of age. Preoperative ultrasound may be helpful for diagnosis. The repair procedure is the classic herniorrhaphy with high ligation of the hernia sac, through an inguinal approach.

Corrección de hernia de Amyand con malla y apendicetomía: reporte de caso / Amyand's hernia repair with surgical mesh and appendectomy: a case report

RESUMEN La hernia de Amyand se define como la presencia de un apéndice vermiforme dentro de un saco herniario inguinal. Menos del 1 % de las publicaciones médicas sobre hernias en el mundo corresponde a este padecimiento, y los reportes en Latinoamérica y el Caribe son escasos. Este artículo describe el caso de un varón de 78 años con un cuadro clínico de cinco meses de evolución aproximadamente. El paciente refiere que sentía una masa en la región inguinal derecha de crecimiento progresivo. Luego se asoció un dolor (de escala 8/10) durante los dos días previos al ingreso en el departamento de urgencias. Durante la operación en la región inguinal derecha, se abre el saco herniario que muestra partes del colon derecho, el ciego y el apéndice (edematosos), por lo que se decide realizar una apendicectomía y la reconstrucción con una malla de polipropileno.

ABSTRACT Amyand's hernia is defined as the presence of the vermiform appendix within an inguinal hernial sac. Less than 1 % of the world medical publications on hernias address this disease, out of which very few come from Latin America and the Caribbean. This is the case of a 78-year-old male patient who experienced signs and symptoms for approximately five months. He felt a lump in the right inguinal region which progressively increased in size. Two days prior to admission to the intensive care unit, he said his pain level was 8/10. During the right inguinal approach, the hernial sac was opened, revealing parts of the right colon, cecum and appendix with edematous changes. Therefore, the patient underwent an appendectomy and repair with polypropylene mesh.

A clinical study on the treatment of giant inguinal hernia in the elderly with L-shaped laparoscopic retractor-assisted transabdominal preperitoneal repair / 中华老年医学杂志

Objective:To assess the clinical efficacy of transabdominal preperitoneal(TAPP)repair aided by the L-shaped laparoscopic retractor in the treatment of giant inguinal hernia in the elderly.Methods:A total of 180 elderly patients with giant inguinal hernias from 2020 to 2021 were randomly divided into an observation group and a control group with 90 in each group.The observation group underwent TAPP surgery with the L-shaped laparoscopic hook-assisted exposure, and the control group underwent conventional laparoscopic TAPP surgery.Results:Operative time[(56.8±8.3)min vs.(62.5±6.9)min, t=3.509, P=0.001], intraoperative bleeding[(18.0±5.3)ml vs.(22.2±5.59)ml, t=3.698, P<0.001], time to first postoperative flatus[(17.8±1.6)h vs.(18.7±1.4)h, t=3.043, P=0.003], postoperative 2d VAS pain score[(1.3 ± 0.3)points vs.(1.6 ± 0.3)points, t=3.509, P=0.001], length of hospital stay[(2.7±0.5)d vs.(4.1±0.6)d, t=3.746, P<0.001]and incidence of complications(3.3% vs.18.9%, χ2=4.406, P=0.036)in the observation group were significantly lower than in the control group.There was no significant difference in the recurrence rate between the two groups during month 6-9 follow-up( P>0.05). After treatment, the levels of tumor necrosis factor, C-reactive protein and interleukin-6 in the observation group were more favorable than in the control Group(all P<0.05). Conclusions:L-shaped laparoscopic hook-assisted exposure in TAPP for the treatment of giant inguinal hernias in the elderly has the advantages of easy maneuver, increased exposure of the anterior bladder, shortened operative time, reduced surgical trauma, and early postoperative recovery.It is also safe and should be recommended in clinical practice.

Evolution and research progress of mesh fixation in laparoscopic trans-abdominal preperitoneal hernia repair / 国际外科学杂志

Since the development of tension-free hernia repair, the choice of mesh type and fixation mode has become a problem that surgeons must consider in operation. The selection of appropriate mesh fixation mode is of great significance to the prognosis of patients. In recent years, with the development of laparoscopic technology and hernia repair materials, new mesh types and mesh fixation techniques have been popularized in clinical practice, tack fixation and suture fixation have been less used in trans-abdominal preperitoneal hernia repair, and medical glue and self-gripping mesh have become the mainstream choice. Some scholars believe that in addition to large direct hernia, vacuum suction fixation is also a safe and effective fixation method. The best method of mesh fixation is still controversial, and the choice of intraoperative fixation methods is also to reach a unified standard. This paper reviews the advantages and disadvantages of different mesh fixation methods in trans-abdominal preperitoneal hernia repair, as well as the selection of intraoperative fixation methods, in order to provide basis for clinicians' intraoperative selection.

Hernia de Amyand, Manejo Quirúrgico ante un Diagnóstico Infrecuente

Resumen La hernia de Amyand es un tipo raro de presentación de la hernia inguinal cuyo contenido es el apéndice cecal, con reportes de incidencia menor al 1%. Debido a la baja frecuencia en la presentación de este tipo de hernia, resulta interesante analizar el caso de un paciente masculino de 80 años con cuadro clínico de dolor inguinal derecho de inicio súbito e imágenes compatibles con una hernia inguinal derecha complicada. El hallazgo del apéndice cecal durante el tiempo operatorio resulta impactante, donde finalmente se decide realizar una hernioplastía asociada a apendicectomía. Es conocido que la hernioplastía está entre los procedimientos más frecuentes y con técnicas quirúrgicas estandarizadas. Sin embargo, en la literatura encontramos divergencia sobre el manejo adecuado de una hernia tipo Amyand. Por tanto, tras una revisión bibliografía motivada por el caso, es posible considerar que para la reparación final de una hernia de Amyand debe tomar en cuenta a la presentación clínicas y patológica de cada paciente, la experiencia del cirujano y los insumos disponibles en el ámbito intrahospitalario para mayor beneficio que guiarán la mejor terapia para el paciente.

Abstract Amyand's hernia is a rare type of inguinal hernia presentation whose content is the cecal appendix, with reports of an incidence lower than 1%. Due to the low frequency in the presentation of this type of hernia, it is interesting to analyze the case of an 80-year-old male patient with a clinical case of sudden onset right inguinal pain, with CT scan compatible with a complicated right inguinal hernia. The finding of the cecal appendix in the hernial sac comes on as a surprise, where finally it was decided to perform a hernioplasty associated with an appendectomy. It is known that hernioplasty is among the most frequent procedures with standardized surgical techniques. However, in the literature, we find disagreements about the proper management of an Amyand-type hernia. Therefore, after a review of the bibliography that was motivated by the case, it is possible to consider that for the final repair of an Amyand hernia, the clinical and pathological presentation of each patient, the experience of the surgeon and the supplies available in the operating room must be taken into account for a greater benefit that will guide the best therapy for the patient.

Liposarcoma vulvar desdiferenciado con diferenciación homóloga a liposarcoma pleomórfico: reporte de caso / Dedifferentiated vulvar liposarcoma with homologous differentiation to pleomorphic liposarcoma: case report

Resumen ANTECEDENTES: Los liposarcomas son un tipo de tumor de partes blandas. El subtipo desdiferenciado es una de las variantes más comunes junto con el liposarcoma bien diferenciado. CASO CLÍNICO: Paciente de 68 años que acudió a consulta por aparición de una masa en la zona vaginal que clínicamente se diagnosticó como hernia inguinal directa. Se procedió a la resección quirúrgica de la masa. El reporte histopatológico fue de miofibrolipoma, sin atipias y con bordes libres de neoplasia. Tres años después, la paciente retornó a la consulta por reaparición de la masa y se negó a una nueva biopsia. Posteriormente, en el 2020, la paciente aceptó la resección de la masa; el reporte histopatológico fue: liposarcoma desdiferenciado con diferenciación lipoblástica homóloga a liposarcoma pleomórfico. CONCLUSIÓN: Los estudios histopatológicos son necesarios para la confirmación del diagnóstico y la resección quirúrgica es el tratamiento de elección.

Abstract BACKGROUND: Liposarcomas are a type of soft tissue tumor. The dedifferentiated subtype is one of the most common variants along with well-differentiated liposarcoma. CLINICAL CASE: A 68-year-old female patient presented for consultation due to the appearance of a mass in the vaginal area which was clinically diagnosed as a direct inguinal hernia. Surgical resection of the mass was performed. The histopathological report was myofibrolipoma, without atypia and with borders free of neoplasia. Three years later, the patient returned to the office for recurrence of the mass and refused a new biopsy. Subsequently, in 2020, the patient accepted the resection of the mass; the histopathologic report was: dedifferentiated liposarcoma with lipoblastic differentiation homologous to pleomorphic liposarcoma. CONCLUSION: Histopathological studies are necessary for confirmation of the diagnosis and surgical resection is the treatment of choice.

Laparoscopic inguinal hernia repair: the long-term assessment of chronic pain and quality of life / Herniorrafia inguinal laparoscópica: avaliação a longo prazo da dor crônica e qualidade de vida

ABSTRACT BACKGROUND: Laparoscopic approaches to inguinal hernia repair include transabdominal extraperitoneal and transabdominal preperitoneal, both of which are widely performed and employ mesh. Indicators of success for these surgical procedures include incidence of complications, time to return to daily activities, incidence of postoperative chronic pain, and the long-term postoperative patient satisfaction. OBJECTIVE: This study aimed to evaluate and compare long-term postoperative incidence of chronic pain and overall quality of life among patients undergoing transabdominal extraperitoneal or transabdominal preperitoneal inguinal hernia repair. METHODS: This was a retrospective cross-sectional study. Medical records were analyzed, and the SF-36 questionnaire and Visual Analog Scale were applied to assess quality of life and chronic pain in patients undergoing laparoscopic inguinal hernia repair between January 2017 and February 2021. RESULTS: A total of 167 patients status post laparoscopic inguinal hernia repair, who were 3 months postoperatively or longer, were included in the study. Among the early complications seen, seroma was most common in the transabdominal preperitoneal group (p=0.04). Subsequently, 40 of the initial 167 patients answered to the survey instrument (SF-36 and Visual Analog Scale). Mean patient-reported pain (Visual Analog Scale score) was statistically similar between groups, with 1.29 for transabdominal preperitoneal and 1.68 for transabdominal extraperitoneal (p=0.92). In the domains evaluated by the SF-36, there was no significant difference between the samples. CONCLUSION: Both transabdominal extraperitoneal and transabdominal preperitoneal techniques for hernia repair have similar results in the late postoperative period regarding quality of life and prevalence of chronic pain. They are also comparable in terms of major early postoperative complications, except for seroma, with a higher incidence in patients undergoing transabdominal preperitoneal.

RESUMO RACIONAL: Atualmente o tratamento da hérnia inguinal pode ser laparoscópico totalmente extraperitoneal ou transabdominal pré-peritoneal, ambas as técnicas utilizam tela e são amplamente empregadas. O sucesso do procedimento cirúrgico é medido pelo menor número de complicações, retorno rápido às atividades cotidianas, presença ou não de dor crônica e pelo grau de satisfação do paciente no pós-operatório. OBJETIVOS: Avaliar e comparar a presença de dor crônica e qualidade de vida no pós operatório tardio de pacientes submetidos às duas técnicas de cirurgias laparoscópicas de correção de hérnia inguinal. MÉTODOS: O estudo consistiu em uma abordagem quantitativa transversal retrospectiva. Foi realizada análise de prontuários e aplicação de questionário SF-36 e Escala Visual Analógica para avaliação de qualidade de vida e dor crônica em pacientes submetidos a hernioplastia inguinal laparoscópica entre janeiro de 2017 a fevereiro de 2021. RESULTADOS: Foram analisados 167 prontuários com mais de 3 meses de pós-operatório. Dentre as complicações precoces avaliadas, o seroma foi mais comumente diagnosticado no grupo transabdominal pré-peritoneal (p=0,04). Posteriormente, 40 dos 167 pacientes responderam ao instrumento de pesquisa composto por SF-36 e Escala Visual Analógica. A média para dor crônica, mensurada através da Escala Visual Analógica, foi de 1,29 para transabdominal pré-peritoneal versus totalmente extraperitoneal com 1,68 (p=0,92). Já nos domínios avaliados pelo SF-36 não houve diferença significativa entre as amostras (p>0,05). CONCLUSÕES: As técnicas totalmente extraperitoneal e transabdominal pré-peritoneal apresentam resultados semelhantes no pós-operatório tardio com base na qualidade de vida e dor crônica. As técnicas também são comparáveis em termos das principais complicações pós-operatórias precoces, exceto para seroma, que apresentou maior incidência em pacientes submetidos a transabdominal pré-peritoneal.
