More than 20 million surgeries of inguinal hernia repair are performed annually around the world. Within the many surgical techniques developed to treat inguinal hernia, the most appropriate technique was in the past chosen based on the recurrence rate. However, with the technological advances in the surgical field, the recurrence rate decreased substantially for all surgical procedures. Recently, postoperative pain is one the major problems related to the surgical treatment of inguinal hernia, as it directly affects the quality of life of patients. Besides, despite the high rate of inguinal hernia cases, there are few comparative studies on the postoperative pain, which evaluate pain for a period longer than 48h after the surgical procedure. Therefore, the objective of this study was to compare the postoperative pain levels between the surgical techniques of open Lichtenstein (LC) and the transabdominal pre-peritoneal laparoscopy (TAPP) for the treatment of unilateral primary inguinal hernia. In this clinical study were included 60 patients, of both sexes and with age between 26 and 69 years, of which 30 were operated using the LC technique and 30 using the TAPP technique. Four patients, two of each group, were excluded from the study as they did complete the all the postoperative. The pain levels were evaluated through the analogue visual scale (AVS) on the days 2, 10 and 30 after the surgical procedure. Additionally, the recurrence rate, presence of chronic pain and paresthesia were evaluated 12 months after the surgery. The analysis of the data demonstrated significant differences on the pain levels between the surgical procedures LC and TAPP, with differences also for the postoperative days. For 2 days after the surgery, there were no differences on pain levels. Differently, for the days 10 and 30 after the surgery, the TAPP technique (1,4 and 0,4 respectively) promoted significantly lower pain levels on the AVS compared to the LC technique (2,3 and 1,3 respectively). Despite both surgical techniques presented no recurrent hernias 12 months after the surgery, chronic pain was lower for the group operated through the TAPP technique compared to the LC technique, occurring in 3.6% and 32% respectively. Moreover, the rate of seroma occurrence and analgesic administration was lower for the TAPP technique. In conclusion, this study demonstrated that there are differences between the surgical techniques, with the TAPP procedure promoting significantly lower postoperative pain (10 and 30 days) and chronic pain (12 months) compared to the LC procedure. Thus, this study is of great importance helping surgeons to choose the most efficient and less painful technique for the surgical repair of unilateral primary inguinal hernia. / O tratamento cirúrgico de hérnia inguinal é um dos procedimentos médicos mais realizados em diversos países, incluindo o Brasil. Mais de 20 milhões de cirurgias de reparo de hérnia inguinal são realizadas anualmente em todo o mundo. Entre as diversas técnicas cirúrgicas desenvolvidas para o tratamento de hérnias inguinais, a escolha da técnica mais apropriada era, no passado, baseada na taxa de recidiva. No entanto, com os avanços tecnológicos na área cirúrgica, a taxa de recidiva diminuiu significativamente em diversas técnicas. Atualmente, a dor pós-operatória é um dos maiores problemas relacionados à correção de hérnia inguinal, pois afeta diretamente a qualidade de vida dos pacientes. No entanto, apesar da alta frequência de hérnia inguinal, ainda existem poucos estudos comparativos da dor pós-operatória, que avaliam a dor por período superior à 48h de cirurgia. Assim, o objetivo principal deste estudo foi de comparar o nível de dor pós-operatória entre a técnica aberta de Lichtenstein (LC) e a técnica laparoscópica pré-peritoneal transabdominal (TAPP) no tratamento de hérnia inguinal unilateral não recidivada. Foram incluídos neste estudo 60 pacientes de ambos os sexos com idade entre 26 e 69 anos, dos quais 30 foram operados pela técnica de LC e 30 pela técnica TAPP, sendo que quatro pacientes foram excluídos por não retornarem no pós-operatório. A intensidade da dor foi avaliada por meio da escala visual analógica (EVA) nos dias 2, 10 e 30 de pós-operatório. Além disso, a taxa de recidiva, a presença de dor crônica e parestesia foram avaliadas 12 meses após a cirurgia. A análise dos dados avaliados demonstrou que existem diferenças significativas nos níveis de dor pós-operatória entre as técnicas LC e TAPP, com diferenças no nível de dor entre os dias de pós-operatório. Com 2 dias de pós-operatório, não foram encontradas diferenças no nível de dor entre as técnicas cirúrgicas. Diferentemente, com 10 e 30 dias de pós-operatório, a técnica TAPP (1,4 e 0,4 respectivamente) promoveu um nível de dor significativamente menor na escala EVA, comparado à técnica LC (2,8 e 1,3 respectivamente). Além disso, apesar de ambas as técnicas não promoverem recidiva após 12 meses da cirurgia, a dor crônica foi menor no grupo operado pela técnica TAPP do que no grupo operado pela técnica LC, ocorrendo em 3,6% e 32% dos pacientes, respectivamente. Os pacientes operados pela técnica TAPP também apresentaram uma taxa menor de seroma e de uso de medicamento analgésico. Concluindo, neste estudo foi demonstrado que existem diferenças na dor pós-operatória entre as técnicas cirúrgicas, sendo que a técnica TAPP apresentou um nível de dor pós-operatória (10 e 30 dias) e dor crônica (12 meses) significativamente menor que a técnica LC. Finalmente, este estudo é de grande importância, pois auxiliará cirurgiões na escolha da técnica mais efetiva e menos dolorosa para o reparo da hérnia inguinal não recidivada.

Introdução: A Laserterapia de Baixa Intensidade (LTBI) é uma terapia que tem se mostrado eficiente na reparação tecidual em trabalhos com cultura celular e experimentos animais, mas existe uma escassez de trabalhos com cicatrização de incisões pós-cirúrgicas em humanos utilizando laser infravermelho GaAlAs de 830nm. O objetivo desse trabalho foi investigar a eficácia do laser infravermelho GaAlAs de 830nm no processo de cicatrização de incisão póscirúrgica de hérnia inguinal Métodos: 28 pacientes submetidos à cirurgia de hérnia-inguinal foram divididos randomicamente em grupo experimental (G1) e grupo controle (G2). O G1 recebeu tratamento com laser, sendo a primeira aplicação 24hs após a cirurgia e as demais dia sim dia não até um total de 4 aplicações. Ambos os grupos foram reavaliados após 6 meses por meio da Escala de cicatriz de Vancouver (ECV) e Escala visual analógica (EVA) e da espessura da cicatriz. As incisões foram irradiadas com laser diodo, =830 nm, 40 mW de potência de saída, 0,08cm² de diâmetro da ponteira de emissão, 26 segundos, 1,04J de energia por ponto e fluência de 13J/cm². Resultados: O G1 apresentou melhora significativa nas médias (p<0,05) da soma total da VSS 11 G1 2,14(±1,51) e G2 4,85(±1,87), na espessura G1 (0,11) e G2 (0,19) e na elasticidade da cicatriz G1 (0,14) e G2 (1,07). Conclusão: De acordo com os resultados obtidos nesse trabalho o tratamento com laser (830nm), usado na cicatrização de cirurgias de hérnia inguinal conseguiu melhorar a aparência e a qualidade da cicatriz seis meses após a incisão. / Background: Low Level Laser Therapy (LLLT) has been shown to be beneficial in the tissue repair process as shown in work done with tissue culture and animal experiments. However, there is a scarcity of work done with regard to post-surgical scarring of incisions in humans using infrared, 830nm, GaAlAs laser. The purpose of this study was to investigate the efficacy of an infrared, GaAlAs laser with a wavelength of 830nm in the post surgical scarring process after Inguinal Hernia Surgery. Method: 28 patients who underwent surgery for Inguinal Hernias were randomly divided into an Experimental Group (G1) and a Control Group (G2). The G1 received low level laser treatment (LLLT) with the first application being made 24 hours after surgery and then every other day for a total of 4 applications. Both Groups were re-evaluated after 6 months using the Vancouver Scar Scale (VSS), the Visual Analog Scale (VAS), and a measurement of scar thickness. The incisions were irradiated with an 830 nm diode laser operating with a continuous output power of 40 mW, spot size aperture of 0.08cm ², 26 seconds, an energy per point of 1.04J and energy density of 13J/cm ². Results: The G1 showed significantly better results; in the VSS totals (2.14±1.51) versus G2 (4.85±1.87), in the thickness measurements G1 (0.11 cm) versus G2 (0.19 cm), and in the pliability G1 (0.14) versus G2 (1.07). Conclusion: According to the results of this work LLLT (830nm) of Inguinal Hernia Scars resulted in better appearance and scar quality six months after surgery.

Approximately one in four men will have surgery for ingunial hernia in their lifetime. In Sweden, 16 000 procedures are performed each year. To investigate the possible link between handling of nerves and sensory disturbance, 97 groins in 92 patients were examined one year after inguinal hernia surgery. Sensory disturbances were found to be common after open surgery (29 %), but were not seen after the laparoscopic procedures. No significant relationship between sensory disturbance and handling of nerves or pain was seen. The risk for recurrence has been significantly reduced due to the use of prosthetic meshes, but continued surveillance of this important outcome will always be necessary. In that context, the time frame in which recurrence develops in relation to possible risk factors can help our understanding of the underlying mechanisms. To explore such temporal relationships, 142,578 patients were included in a register study. A relative over-risk for early recurrence was seen after suture repair, laparoscopic repair, after postoperative complications, and after surgery for previous recurrence. Corticosteroids are known to decrease pain and nausea after several surgical procedures. In a randomised trial on open hernia surgery, 398 patients were randomised to treatment with 12 mg of betamethasone or placebo. Decreased levels of pain were seen on the day of surgery, the next day and after one month. No difference was seen on days 2-7 and after one year. Nausea was not common and did not differ between the groups. Reoperation is sometimes performed to correct a presumed structural defect thought to cause the long-term pain. In order to evaluate the result of such treatment, 111 cases were analysed based on register data, questionnaires and medical records. Sixty-two per-cent of the patients reported an improvement compared to before the reoperation, but a high level of pain remaining (42 %), and impaired quality of life was seen. There was no clear advantage for any surgical intervention over the other.

Objetivos: Determinar si hay diferencias significativas en la frecuencia de complicaciones tempranas y tardías secundarias al uso de las técnicas de Lichtenstein y Nyhus en el manejo de hernias inguinales en el Hospital Militar Central. Material y métodos: Se realizó un estudio de tipo transversal con los registros quirúrgicos e historias clínicas de los pacientes con diagnóstico de hernia inguinal tratados quirúrgicamente en el Hospital Militar Central durante el período 2012-2014. Resultados: Del total de pacientes tratados quirúrgicamente, el 89% se realizó con la técnica de Lichtenstein y el 11% con la técnica de Nyhus. Al comparar ambas técnicas no encontraron diferencias en términos de tiempos quirúrgicos (43.0 ± 13.6 vs. 39.1 ± 8.9 minutos, p =0.140) y tiempos de hospitalización (3.9 ± 1.2 vs. 3.8 ± 0.8 días, p =0.635). Al comparar la frecuencia se encontraron diferencias significativas en la complicaciones tempranas (17% vs. 0%, p =0.028) pero no en el caso de las complicaciones tardías (4% vs. 0%, p =0.603). Conclusiones: Las técnicas de Lichtenstein y Nyhus demostraron ser seguras en el manejo quirúrgico de las hernias inguinales. Ambas se asociaron a niveles bajos de complicaciones, siendo las complicaciones tempranas significativamente más frecuentes entre los casos tratados con la técnica de Lichtenstein.

Método: homens portadores de hérnia inguinal, com idade igual ou superior a 50 anos, que compareceram ao ambulatório de cirurgia geral no período de maio de 2003 a novembro de 2005, foram submetidos ao estudo urodinâmico, sendo avaliados principalmente a resistência uretral média (URA), a contratilidade isométrica detrussora (Pw) e o resíduo miccional. Os pacientes foram divididos em um grupo sem uso da manobra de Valsalva durante a micção (grupo I) e outro com presença da manobra (grupo II). Inicialmente, os dados foram expressos através das médias dos parâmetros analisados; após foram dicotomizados conforme os valores de referência; e, para análise estatística, empregou-se o teste do qui quadrado e regressão logística não condicional. Resultado: Participaram 100 pacientes, com média de idade de 64,2 anos (DP de +-9,7 anos). O grupo I foi composto por 52 pacientes e o grupo II, por 48 pacientes. As médias dos parâmetros urodinâmicos foram comparadas entre os dois grupos. Constatou-se que o grupo que realizava manobra de Valsalva 33 durante a micção apresentava uma contratilidade detrussora comprometida (p<0,01) e um resíduo miccional aumentado (p<0,02). Ao utilizar-se a regressão logística para expressar as razões de odds, foi encontrado OR de 2,57 (IC 95%: 1,09-6,06) no grupo de hipocontratilidade detrussora. Conclusão: a manobra de Valsalva durante a micção associa-se com a presença de hipocontratilidade detrussora em portadores de hérnia inguinal

Inguinal hernia repair is the most common operation in general surgery. Its main challenge is to achieve low recurrence rates. With the introduction of mesh implants, first in open and later in laparoscopic repair, recurrence rates have decreased substantially. Therefore, the focus has been shifted from clinical outcome, such as recurrence, towards patient-experienced endpoints, such as chronic pain. In order to compare the results of open and laparoscopic hernia repair, a randomised multicentre trial - the Swedish Multicentre trial of Inguinal hernia repair by Laparoscopy (SMIL) - was designed by a study group from 11 hospitals. Between November 1996 and August 2000, 1512 men aged 30-70 years with a primary inguinal hernia were randomised to either laparoscopic (TEP, Totally ExtraPeritoneal) or open (Lichtenstein) repair. The primary endpoint was recurrence at five years. Secondary endpoints were short-term results, frequency of chronic pain and a cost analysis including complications and recurrences up to five years after surgery. In total, 1370 patients, 665 in the TEP and 705 in the Lichtenstein group, underwent operation. With 94% of operated patients available for follow-up after 5.1 years, the recurrence rate was 3.5% in the TEP and 1.2% in the Lichtenstein group. Postoperative pain was lower in the TEP group up to 12 weeks after operation, resulting in five days less sick leave and 11 days shorter time to full recovery. Patients in the TEP group had a slightly increased risk of major complications. Chronic pain was reported by 9-11% of patients in the TEP and 19-25% in the Lichtenstein group at the different follow-up points. Hospital costs for TEP were higher than for Lichtenstein, while community costs were lower due to shorter sick leave. By avoiding disposable laparoscopic equipment, the cost for TEP would be almost equal compared with Lichtenstein. In conclusion, both TEP and Lichtenstein repair have advantages and disadvantages for the patient. Depending on local resources and expertise both methods can be used and recommended for primary inguinal hernia repair.
