Chronic pain after two laparoendoscopic inguinal hernia repairs compared with laparoendoscopic repair followed by the Lichtenstein repair: an international questionnaire study.

BACKGROUND: The best repair of a recurrent inguinal hernia after primary laparoendoscopic repair is debatable. The aim was to assess chronic pain after two laparoendoscopic repairs in the same groin compared with Lichtenstein reoperation preceded by a laparoendoscopic repair. METHODS: This cohort study included adult patients who had received two laparoendoscopic repairs (Lap-Lap) or a laparoendoscopic repair followed by the Lichtenstein repair (Lap-Lich). Eligible patients were identified in the Danish and the Swedish hernia databases. Lap-Lap was matched 1:3 with Lap-Lich, and patients were sent validated questionnaires. The primary outcome was the proportion with chronic pain-related functional impairment, compared between the two groups. Secondary outcomes included chronic pain during various activities. RESULTS: In total, 74% (546 patients) responded to the questionnaires with a median follow-up since the second repair of 4.9 years (0.9-21.9 years). Regarding the primary outcome, 21% in Lap-Lap and Lap-Lich had chronic pain-related functional impairment of daily activities (p = 0.94). More patients in Lap-Lap compared with Lap-Lich reported pain ≥ 20 mm measured by the visual analog scale, 11% versus 5%, p = 0.04. However, there was no difference in the median VAS score or in the vast majority of the remaining secondary outcomes. CONCLUSIONS: There was no overall difference in chronic pain between patients who had received Lap-Lap compared with Lap-Lich. Choice of operative strategy for the second repair should, therefore, not be based on risk of chronic pain.

Comparación de resultados entre hernioplastia inguinal abierta con malla tipo liechtenstein y hernioplasta inguinal videolaparoscópica / Outcome Measures between Open Lichtenstein Technique and laparoscopic TAPP Repair of Inguinal Hernias

Introducción: la hernioplastía es uno de los procedimientos quirúrgicos más comunes que realiza el cirujano alrededor del mundo. En nuestra institución se realizan la hernioplastía tipo Liechtenstein (abierto) y videolaparoscópica tipo TAPP (transabdominal preperitoneal). El objetivo del estudio es comparar los resultados obtenidos utilizando ambos procedimientos. Diseño, lugar y participantes: estudio retrospectivo de 45 pacientes sometidos a uno de los dos procedimientos, durante junio-noviembre 2015, en el Hospital General Juan José Arévalo Bermejo, evaluando la prevalencia de inguinodinia crónica, hernia recidivante, complicaciones y tiempo de retorno a labores. Resultados: No se encontró diferencia, entre el grupo abierto comparado con el videolaparoscópico, en la prevalencia de inguinodinia crónica (21.4% vs 17.7%, p: 0.75), ni en el porcentaje de pacientes que consultó a la emergencia por dolor (8.5% vs 13%, p: 0.55), ni en complicaciones postoperatorias de infección, seroma, rechazo e hidrocele (19.1% vs 30.4%, p: 0.36). Las recidivas de hernia inguinal fueron más comunes en el grupo videolaparoscópico que en el abierto (17.3% vs 2.1%; p: 0.019). El tiempo promedio de retorno a labores fue de 29 días en ambos grupos (p: 1.0) Conclusión: En nuestra institución, ambos procedimientos tiene resultados comparables y probablemente, conforme aumente la experiencia de la hernioplastía videolaparoscópica, la incidencia de recidivas disminuya.

Background: Hernioplasty is one of the most common surgical procedures around the world. In our insttuton hernioplasty is performed with Lichtenstein technique (open) and laparoscopic TAPP (transabdominal preperitoneal) repair. The aim of the study is to compare clinical outcomes between both procedures. Design, Setng, and Partcipants: In this retrospectve study, 45 patents were treated with one of the techniques for hernia repair, between June and November of 2015 at the General Hospital Juan José Arévalo Bermejo. The prevalence of chronic inguinodynia, inguinal hernia recurrence, complicatons and tme to return to normal actvites were compared. Results: There is no statstcal diference between open technique compared with laparoscopic repair, in the prevalence of chronic inguinodynia (21.4% vs 17.7%, p: 0.75), nor in the percentage of patents that were atended in the emergency room for pain (8.5% vs 13%, p: 0.55), nor in postoperatve infectons, seroma formaton, rejecton or hydrocele complicatons (p: 0.36). Inguinal hernia recurrence was more common in the laparoscopic group (17.3% vs 2.1%, p: 0.019). Mean tme to return to work was 29 days in both groups (p: 1.0). Conclusions: In our insttuton both procedures have comparable results and more experience is needed to decrease hernia recurrence.

Analysis of Risk Factors of Recurrent Inguinal Hernia by Cox Proportional Hazard Regression Model / 中国普外基础与临床杂志

Objective To retrospectively analyze the risk factors of recurrent groin hernia. Methods Data came from all hernia repairs recorded in our hospital between 1991 and 2001. A total of 1 082 cases of groin hernia was analyzed through Cox proportional hazard model to determine the relative risks between recurrence and mode of admission, types of groin hernia, repair methods (traditional/tension free hernioplasty), and post operative complications.Results From 1991 to 2001,1 082 groin hernia operations were performed in our hospital, 88.9% for primary hernia and 11.2% for recurrent hernia. As compared with traditional hernia repair methods, Lichtenstein’s tension free hernioplasty technique had less relative risk for recurrent hernia repair than that for primary hernia repair. Postoperative complications and indirect hernia were linked to an increased relative risk for recurrence. Conclusion There are many factors affecting the recurrence of inguinal hernia, but the use of tension free hernia repair may decrease re recurrence of recurrent hernia.
