Femoral hernia: uncommon, but associated with potentially severe complications / Hérnia femoral: incomum, mas associada a complicações potencialmente graves

ABSTRACT Background: Although the laparoscopic access is becoming the preferable treatment for femoral hernia, there are only few studies on this important subject. Aim: To assess the outcomes of the totally extraperitoneal laparoscopic (TEP) access in the treatment of femoral hernia. Methods: Data of 62 patients with femoral hernia who underwent herniorrhaphy were retrospectively reviewed. The diagnosis of femoral hernia was established by clinical and/or imaging exams in 55 patients and by laparoscopic findings in seven. Results: There were 55 (88.7%) females and 7 (11.3%) males, with female to male ratio of 8:1. The mean age was of 58.9±15.9 years, ranging from 22 to 92 years. Most patients (n=53; 85.5%) had single hernia and the remaining (n=9; 14.5%) bilateral, making a total of 71 hernias operated. Prior lower abdominal operations were recorded in 21 (33.9%) patients. Conversion to laparoscopic transabdominal preperitoneal procedure was performed in four (6.5%). Open herniorrhaphy was needed in two (3.2%), one with spontaneous enterocutaneous fistula in the groin region (Richter's hernia) and the another with incidental perforation of the adjacent small bowel that occurred during dissection of hernia sac. There was no mortality. Conclusion: Femoral hernia is uncommon, and it may be associated with potentially severe complications. Most femoral hernias may be successfully treated with totally extraperitoneal laparoscopic access, with low conversion and complication rates.

RESUMO Racional: Embora o acesso laparoscópico esteja se tornando o tratamento preferencial para a hérnia femoral, poucos são os estudos sobre esse importante assunto. Objetivo: Avaliar os resultados do acesso laparoscópico totalmente extraperitoneal no tratamento da hérnia femoral. Métodos: Os dados de 62 pacientes com hérnia femoral que foram submetidos a herniorrafia foram revisados ​​retrospectivamente. O diagnóstico foi estabelecido por exames clínicos e/ou de imagem em 55 pacientes e por achados laparoscópicos em sete. Resultados: Havia 55 (88,7%) mulheres e 7 (11,3%) homens, com proporção feminino/masculino de 8: 1. A média de idade foi de 58,9±15,9 anos (22-92). A maioria (n=53, 85,5%) apresentava hérnia única e o restante (n=9, 14,5%) bilaterais, perfazendo um total de 71 hérnias femorais operadas. Operações prévias no abdome inferior foram registradas em 21 (33,9%) pacientes. A conversão para procedimento pré-peritoneal transabdominal laparoscópico foi realizada em quatro (6,5%). Herniorrafia aberta foi necessária em dois pacientes (3,2%), um com fístula enterocutânea espontânea na região da virilha (hérnia de Richter) e o outro com perfuração incidental do intestino delgado adjacente que ocorreu durante a dissecção do saco herniário. Não houve mortalidade. Conclusão: A hérnia femoral é incomum e pode estar associada a complicações potencialmente graves. A maioria das hérnias femorais pode ser tratada com sucesso através do acesso laparoscópico totalmente extraperitoneal, com baixas taxas de conversão e complicações.

Primary abandon-of-the-sac (pas) technique: preliminary results of a novel minimally invasive approach for inguinoscrotal hernia repair / Técnica do abandono primário do saco herniário (pas): resultados preliminares de uma nova técnica na cirurgia minimamente invasiva de hérnias inguinoescrotais

ABSTRACT Background: Laparoscopic best approach of repairing inguinoscrotal hernias are still debatable. Incorrect handling of the distal sac can possibly result in damage to cord structures and negative postoperative outcomes as ischemic orquitis or inguinal neuralgia. Aim: To describe a new technique for a minimally invasive approach to inguinoscrotal hernias and to analyze the preliminary results of patients undergoing the procedure. Methods: A review of a prospectively maintained database was conducted in patients who underwent minimally invasive repair using the "primary abandon-of-the-sac" (PAS) technique for inguinoscrotal hernias. Patient´s demographics, as well as intraoperative variables and postoperative outcomes were also analyzed. Results: Twenty-six male were submitted to this modified procedure. Mean age of the case series was 53.8 years (range 34-77) and body mass index was 26.8 kg/m2 (range 20.8-34.2). There were no intraoperative complications or conversion. Average length of stay was one day. No surgical site infections, pseudo hydrocele or neuralgia were reported after the procedure and two patients presented seroma. No inguinal hernia recurrence was verified during the mean 21.4 months of follow up. Conclusion: The described technique is safe, feasible and reproducible, with good postoperative results.

RESUMO Racional: A melhor maneira laparoscópica do reparo de hérnias inguinoescrotais permanece ainda aberta a discussão. O manuseio incorreto do saco herniário pode resultar em danos às estruturas do cordão e resultados pós-operatórios indesejados, como orquite isquêmica ou neuralgia inguinal. Objetivo: Descrever uma nova técnica de abordagem minimamente invasiva das hérnias inguinoescrotais e analisar os resultados preliminares de pacientes submetidos ao procedimento. Métodos: Foi realizada na série de casos a análise retrospectiva de um banco de dados mantido prospectivamente em pacientes submetidos a reparo minimamente invasivo usando a técnica "abandono primário do saco" (PAS) para hérnias inguinoescrotais. Dados demográficos dos pacientes, bem como variáveis intraoperatórias e resultados pós-operatórios são descritos. Resultados: Vinte e seis homens foram submetidos ao procedimento. A idade média foi de 53,8 anos e o índice de massa corpórea de 26,8 kg/m2. Não houve complicações intraoperatórias ou conversão para operação aberta. A duração média da estadia hospitalar foi de um dia. Não foram relatadas infecções de sítio cirúrgico, hematomas ou neuralgia após o procedimento e a presença de seroma ocorreu em dois pacientes. Nenhuma recorrência de hérnia inguinal foi verificada durante média de 21,4 meses. Conclusão: A técnica descrita é segura e replicável, apresentando bons resultados pós-operatórios.

Manejo da dor inguinal crônica pós-hernioplastia (inguinodinia) / Management of chronic pain after inguinal hernioplasty

A dor inguinal crônica pós-herniorrafia é uma situação preocupante, pois aproximadamente 10 por cento dos pacientes submetidos à hernioplastia inguinal apresenta os sintomas, que com frequência limita a capacidade física. A etiopatogênese está relacionada a uma periostite do púbis (dor somática) e mais frequentemente à lesão nervosa (dor neuropática). É importante distinguir clinicamente entre os dois tipos de dor, pois o tratamento pode ser diferente. O médico deve estabelecer uma rotina diagnóstica e de tratamento, sendo que a maior parte dos pacientes necessitarão de terapêutica cirúrgica. A prevenção desta condição é de grande importância e pode levar a uma menor incidência da síndrome. Algumas medidas são fundamentais, como evitar pontos ou clipes no periósteo do púbis, usar criteriosamente as próteses e identificar os nervos da região inguinal. Esta última medida é certamente a mais importante na prevenção da dor crônica e implica em conhecimento profundo da anatomia e o uso de uma técnica aprimorada.

Chronic groin pain after herniorrhaphy is a concern, as approximately 10 percent of patients undergoing inguinal hernia repair have symptoms, which often limit physical ability. The etiopathogenesis is related to periostitis pubis (somatic pain) and more often to nerve injury (neuropathic pain). It is clinically important to distinguish between these two types of pain because treatment can be different. The physician should establish a routine diagnosis and treatment, and most patients will need surgical approach. Prevention of this condition is of great importance and can lead to a lower incidence of the syndrome. Some measures are key, such as how to avoid application of stitches or clips to the pubis periosteum, using the prosthesis carefully and identifying the nerves in the groin. This last measure is certainly the most important in the prevention of chronic pain and involves thorough knowledge of anatomy and the use of refined technique.

Pinzamiento femoroacetabular: Conceptos básicos en una nueva causa de dolor inguinal: [revisión] / Femoroacetabular impingement as a cause of inguinal pain: [review]

Femoro-acetabular impingement is an anatomical disturbance of the hip, caused by a deformity of the acetabulum, femur or both that causes an abnormal contact between both structures during certain movements. Its prevalence is 10 to 15 percent and causes chronic inguinal pain. It can be confused with several other causes of inguinal pain such as hernias, facet syndromes, a renal colic, etc. Patients with this condition are usually young individuals with inguinal pain that may appear after a minor trauma. During examination, pain may be elicited by infernal rotation and abduction movements of hip, flexed in 90°. Plain hip X ray is the most commonly used diagnostic method. Non-steroidal anti-inflammatory drugs and physical therapy can be used to alleviate pain, but the definitive treatment is surgical.

Síndrome de dolor inguinal crónico (SDIC) / Chronic inguinal pain syndrome

Background: Chronic inguinal pain syndrome (CIPS) is a frequent complaint in patents attending to a public ambulatory surgical service. Aim: To report a descriptive observational study of CIPS. Material and Methods: Retrospective review of medical records of patients presenting with CIPS between 1999 and 2006. The symptoms and physical examination of the groin, the spine and the coxofemoral joint of these patients was evaluated. Results: CIPS was diagnosed in 150 patients aged 17 to 71 years, 87 men. They represented 14 percent of groin problems diagnosed in the study period. Median duration of pain was 13 (3-150) months, with remissions that lasted from weeks to months. The charactenstics of pain remained constant in each remission. Pain was present during the daily activities, but it was even worse during resting periods and during night sleep, leading the patient to assume pain reducing positions. Hernia was present in 29 patients and occupied inguinal channel in three. Five patients had a history of previous hernia repair. One hundred twenty patients had spine diseases. An anesthetic blockade of the ilioinguinal nerve was performed in 37 patients with a positive response in seven. Twenty nine of 47 groin ultrasound examinations were informed as abnormal and suggestive of inguinal hernia. Surgical treatment was performed in these patients and was associated with pain abolition in 12, reduction in seven and persistence in the rest. Remaining patients were treated with spine rehabilitation. The short time follow-up of both groups was encouraging. Conclusions: Inguinal hernia and radicular pain due to spine problems are the main causes of CIPS in this series of patients.

El Síndrome de Dolor Inguinal Crónico (SDIC) ha sido un hallazgo frecuente en el Centro de Cirugía Mayor Ambulatoria de las Hernias del CRS Cordillera. Presentamos un estudio observacional descriptivo del SDIC, basado en la información contenida en las fichas clínicas en un período de 7 años. Se estudiaron los síntomas, el examen físico de la región inguinal, de la columna vertebral, de la inervación de la zona y de la articulación coxofemoral. El cuadro clínico afectó a 150 pacientes, 87 varones y 63 mujeres, con una edad promedio de 42 años (17-71). La antigüedad de los síntomas fue en promedio de 13 (3-150) meses apreciándose remisiones de duración variable, de semanas o meses, sin variación de las características neuropáticas del dolor. Si bien éste se presentó durante la actividad, estuvo presente también en el reposo sentado y el nocturno aliviándose con posición antálgica. Se detectó una hernia inguinal en 29, un canal inguinal ocupado en 3 y antecedente de herniorrafia en 5 pacientes. En los restantes 129 pacientes se detectó patología de columna vertebral, apreciándose en todos un examen neurológico alterado. El bloqueo del nervio ilioinguinal se efectuó en 37 pacientes siendo positivo en 7. La ecotomografía de partes blandas de la región inguinal adquiere valor sólo en manos experimentadas. Una operación se realizó ante evidencia de patología inguinal, los demás pacientes fueron sometidos a rehabilitación de la columna vertebral. Los resultados a corto plazo han sido satisfactorios en ambos grupos.
