Inguinal hernia in southern Brazil - challenges in follow-up and recurrence rates / Hérnia inguinal no Sul do Brasil - desafios no seguimento e taxas de recorrência

ABSTRACT Introduction: recurrence rates for primary hernia repair range from 0.5 to 15 percent depending upon the hernia site, type of repair, and clinical circumstances. Many risk factors are known and they must be considered before the procedure. In developing countries, follow up and maintenance of databases are critical to understand the real numbers. Methods: a retrospective cohort study analyzed adult patients who have undergone inguinal hernia repair at Hospital de Clínicas de Porto Alegre, a tertiary care government public hospital, between 2013 and 2015. Medical records, telephone, and letter contact have been reviewed in order to complete the minimum period of 5 years of follow-up. The analyzed data focused on the surgeon's experience and the recurrence rate in 5 years of follow-up. Results: a total of 1094 medical records were selected and a complete five years follow-up were possible in 454 patients - 538 inguinal hernia repairs due to bilateral approach in 84 patients. These 454 patients answered, in a validated questionnaire about symptoms of recurrence. The total recurrence rate was 9.29%. For the patients who had Nyhus IV, recurrence rate was 24.1% against 9.9% after primary hernia repair, with a 2.4 higher risk. There was no difference in recurrence between surgeons and training surgeons. Conclusion: our data reveal an acceptable recurrence rate in a tertiary care hospital with residents, and to our knowledge is the first Brazilian report with long term follow up. An increased re-recurrent hernia was found when compared with primary hernia repair.

RESUMO Introdução: a recorrência da hérnia inguinal após hernioplastia varia de 0,5 a 15 por cento, dependendo do local da hérnia, tipo de reparo e circunstâncias clínicas. Muitos fatores de risco são conhecidos e devem ser considerados antes do procedimento. Acompanhamento e adequado bancos de dados são fundamentais para entender a incidência de recidiva. Métodos: estudo de coorte retrospectivo analisou hernioplastias inguinais realizados no Hospital de Clínicas de Porto Alegre entre 2013 e 2015. Para concluir 5 anos de seguimento, analisamos o prontuário e fizemos contato telefônico e por correio. Resultados: o total de 1094 registros médicos foram selecionados e um seguimento de pelo menos 5 anos foi possível em 454 pacientes - 538 reparos de hérnia inguinal devido à abordagem bilateral em 84 pacientes. Os pacientes responderam um questionário validado sobre sintomas de recorrência. A taxa total de recorrência foi de 9,29%. No grupo masculino, a recorrência foi de 10% contra 4% no grupo feminino. Para os pacientes com hérnia Nyhus IV, a recidiva foi de 24% contra 8% após o reparo da hérnia primária, com um risco de 2,8 maior. Não houve diferença na recorrência entre cirurgiões experientes e em treinamento. Conclusão: nossos dados revelam uma taxa de recorrência aceitável em um hospital de ensino, e para o nosso conhecimento é o primeiro artigo com acompanhamento de longo prazo no sul do Brasil. A re-recidiva da hérnia foi maior quando comparada com o reparo da hérnia primária.

Early and late outcomes of TEP and Lichtenstein repair for recurrent inguinal hernia repair in men: a comparative study

Background: Repair operation for recurrent inguinal hernia is a more exigent than the primary inguinal hernia. Open hernia repair associated with lower recurrence and fewer complications while the Laparoscopic repair associated with less pain postoperatively, early recovery time with subsequent earlier return to activity and better results regarding the wound.Methods: From November 2015 to March 2019, a total of 86 patients were randomized. 42 patients were recruited to total extra-peritoneal repair (TEP) group and 44 patients for Lichtenstein group. Overall, 86 were operated in general surgery department, Menoufia University hospitals.Results: The mean age of patients was 41.3±14.4, range from (25-55 years). One conversion occurred in the TEP group to Lichtenstein. Operative time was significantly low in TEP group (82.7 min) compared to Lichtenstein group (108 min). Hospital stay was significantly less in TEP group (1 day) compared to Lichtenstein group (1.8 days). Patients undergoing Lichtenstein repair have significant earlier oral intake than TEP group (3.7 vs. 6.6 hours). 12 cases developed seroma in Lichtenstein group with significant p value (0.001). This study showed less immediate and early VAS score in TEP group (2.3) versus high VAS score in Lichtenstein group (5.9) with highly significant p value (0.0001).Conclusions: TEP offer excellent results than LR for treatment of unilateral or bilateral recurrent inguinal hernia with lower morbidity and less incidence of post-operative pain with subsequent earlier return to normal activities.

Acute de Garengeot Hernia Masquerading as a Recurrent Inguinal Hernia – A Diagnostic Dilemma.

A de Garengeot hernia is a femoral hernia in which the sac contains the vermiform appendix. herein, we report an interesting case of a de Garengeot hernia with secondary appendicitis presenting acutely in a male patient with previous history of inguinal hernia repair. We discuss the diagnostic dilemmas involved and present a review of current literature.

Patterns of Recurrent Hernias according to the Types of Previous Hernioplasties

PURPOSE: Recently, conventional tissue repairs are gradually being replaced by tension-free hernioplasties using meshes (mesh repairs) in hernia surgery. The aim of the present study was to evaluate patterns of recurrent hernias according to the types of previous hernioplasties. METHODS: From August 2005 to July 2008, 18 hernioplasties were performed in recurrent cases at Chungbuk National University Hospital. All previous hernioplasties were performed at local hospitals except one case of ventral hernia. We reviewed the medical records and compared clinical features according to the types of previous hernioplasties. RESULTS: Among the 18 recurrent hernias, there were 15 inguinal including 2 pediatric cases, an umbilical, and 2 incisional hernias. Among 13 adult inguinal recurrent cases, 5 occurred after tissue repair (3 indirect, 1 direct, and 1 pantaloon type) and 8 after mesh repairs (direct type in all). Recurrence developed earlier after mesh repairs than tissue repairs (median [min~max]; 24 [0.1~164] vs. 243 [60~360] months, P=0.005). Other types of recurrence developed between 6 to 48 months after previous operations. Recurrent hernias after mesh repairs occurred preferentially along the margin of previous meshes. All cases were treated by mesh repairs except in pediatric cases. Median operation time and hospital stay for recurrent inguinal hernias were not different significantly by previous operations. Postoperative complications were minimal without recurrence during a median 5.5-(1.5~25.5)-month follow-up. CONCLUSION: Recurrent hernias develop both after tissue repairs and mesh repairs. After mesh repairs, recurrences develop earlier and are more often associated with technical failure compared to tissue repairs.

Objective To discuss the value of tension-free hernia repair to recurrent inguinal hernia in elderly patients.Methods 38 eases with recurrent inguinal hernia in elderly patients were treated with shaped polyproplene tension-free hernioplasty.Results All eases were operated successfully.In the follow-up period ranged from 6 to 42 months.No Serious postoperation complications were found,no recurrent case recurred.This treatment is effective.Conclusion Tension-free hernia repair has many advantages,such as safety,easily manipulation,minimal invasion,rapid recovery,lower recurrence.It is a perfect and ideal surgical operation for the recurrent inguinal hernia in elderly patients.
