ABSTRACT

ABSTRACT Purpose: To develop a reproducible training program model covering the steps of the extended totally extraperitoneal approach (e-tep) technique for correction of ventral or incisional hernia repair. Methods: Training sessions with surgeons in the laboratory using both porcine specimens and a new ethylene vinyl acetate (EVA) model simulating the operative steps of the e-tep technique. Students were interviewed and asked to answer a questionnaire pre and post the sessions to assess their performance and evaluated the course and model. Results: A total of 25 trained abdominal wall surgeons was evaluated at the end of the course. It was obtained a 100% satisfaction score of the training, as well as increased confidence levels up to 9 and 10 in all technical aspects of the surgery, having 96% of the surgeons performed a surgery under supervision of the proctors after the course. Conclusions: This training model is simple, effective, low cost, and replicable in guidance on the beginning of e-tep technique adoption, and performance. As a result, surgeons can get more confident and more able to perform surgeries employing this technique.

ABSTRACT

ABSTRACT Background: Since publication of our paper "Ten Golden Rules for a Safe MIS Inguinal Hernia Repair" we have received many questions. As the authors, we feel it is important to address these topics as a follow-up to our paper. Aim: To discuss in more details the main points of controversy, review the rules and update de recommendations. Method: The questions and discussions came mainly over five rules, numbered 3, 5, 6, 7, 10. We analyzed all the comments about recommendations and update some technical principles. Results: Rule 3 - Removing normal fat plugs from the obturator canal is unnecessary and therefore is not recommended; Rule 5 - transection of the uterine round ligament (1 cm proximal to the deep ring) facilitates adequate dissection. When performed in this way it does not appear to be associated with complications; Rule 6 - transection of huge sacs are safer than over-dissection of the cord structures. Whether dissecting completely the sac or abandon the distal part it results in less postoperative seromas is an ongoing debate; Rule 7 - any retroperitoneal structure traversing the internal ring is or play a role like a hernia. Failing to identify and remove the lipoma will ultimately result in the patient experiencing a recurrence; Rule 10 - in TAPP peritoneum should preferably be closed with suture than tackes. Conclusion: 10 Golden Rules emphasize the most important surgical tips and technical steps that allow the safe performance of MIS repairs of inguinal hernias, regardless the technique.


RESUMO Racional: Desde a publicação de nosso artigo "Dez Regras de Ouro para o Reparo Seguro de Hérnia Inguinal MIS", recebemos muitos questionamentos. Como autores, sentimos que é importante abordar esses tópicos como seguimento do artigo Objetivo: Discutir com mais detalhes os principais pontos de controvérsia, revisar as regras e atualizar as recomendações. Método: As dúvidas e discussões surgiram principalmente sobre cinco regras, numeradas 3, 5, 6, 7, 10. Analisamos todos os comentários sobre as recomendações e atualizamos alguns dos princípios técnicos. Resultados: Regra 3 - remoção dos plugs de gordura normais do canal obturador é desnecessária e, portanto, não é recomendada; Regra 5 - transecção do ligamento redondo do útero (1 cm proximal ao anel profundo) facilita a dissecção adequada e quando realizado dessa forma, não parece estar associada com complicações; Regra 6 - transecção de grandes sacos herniários é mais segura do que a dissecção excessiva das estruturas do cordão espermático e, se dissecar completamente o saco ou abandonar a parte distal, resulta em menos seromas pós-operatórios ainda é motivo de debate; Regra 7 - qualquer estrutura retroperitoneal que atravessa o anel interno é ou desempenha o papel como uma hérnia e deixar de identificar e remover o lipoma acabará resultando em recorrência; Regra 10 - na TAPP o peritônio deve ser fechado preferencialmente com sutura do que com tacks. Conclusão: As 10 Regras de Ouro enfatizam as dicas cirúrgicas e etapas técnicas mais importantes que permitem a realização segura de reparos MIS de hérnias inguinais, independentemente da técnica.

ABSTRACT

Introdução: Comparar o índice de aderências intraperitoneais entre a tela de submucosa intestinal suína (Surgsis®) e tela polipropileno intraperitoneal (Marlex®) em modelo animal. Metodologia: Foram analisados três grupos de ratas albinas totalizando 40 animais grupo 0 (Sham operation sem tela) = 5 ratos, grupo 1 (tela de polipropileno) = 15 ratos, grupo 2 (tela de submucosa intestinal suína intraperitoneal) = 20 ratos. Estes foram anestesiados com xilasina (5mg/kg) e quetamina (50mg/kg) para a realização do procedimento. Após 21 dias, os animais foram mortos e avaliou-se o percentual de tela comprometida, o tipo de víscera envolvida, o tipo de aderência (graduado de 0 ­ ausência de aderências, a 3 ­ aderências firmes), bem como a força necessária para sua ruptura. Resultados: No grupo 1, todos os animais apresentaram aderências, sendo as aderências 2 e 3 os tipos mais freqüentes (86,6%). Em um animal houve aderência firme do intestino delgado. No grupo 2, foram encontradas aderências do tipo 0 e 1 em 75% dos animais; as do tipo 3 não foram encontradas. Quando comparados, os grupos diferiram estatisticamente (p<0,001) em todos os parâmetros avaliados. Conclusão: A tela de Marlex® apresentou índices elevados de aderências, o que pode representar uma maior possibilidade de complicações pós-operatórias (AU)


Introduction: To compare the rate of intraperitoneal adhesions between the porcine intestinal submucosa surgical mesh (Surgsis®) and intraperitoneal polypropylene mesh (Marlex®) in animal model. Methodology: A total of 40 albino female rats divided in three groups were analyzed: Group 0 (Sham operation without mesh) = 5 rats, Group 1 (polypropylene mesh) = 15 rats, and Group 2 (intraperitoneal intestinal submucosa mesh) = 20 rats. The animals were anesthetized with xylasine (5mg/kg) and ketamine (50mg/kg) prior to the procedure. After 21 days, the animals were killed and we evaluated the percentage of compromised mesh, the type of viscera involved, the type of adhesions (rated in a scale from 0 =absence of adhesions to 3 = firm adhesions), as well as the necessary force for their rupture. Results: All animals in Group 1 presented adhesions, types 2 and 3 being the most frequent ones (86.6%). One animal had firm adhesion of the small intestine. In Group 2, adhesions type 0 and 1 were found in 75% of the animals, and type 3 was not found. When the groups were compared, they were statistically different (p<0.001) in all the evaluated parameters. Conclusion: The Marlex® mesh presented higher rates of adhesion, which can increase the possibility of postoperative complications (AU)
