Psychological risk factors for chronic post-surgical pain after inguinal hernia repair surgery:a prospective cohort study.

A significant proportion of patients experience chronic post-surgical pain (CPSP) following inguinal hernia surgery. Psychological models are useful in predicting acute pain after surgery, and in predicting the transition from acute to chronic pain in non-surgical contexts. This is a prospective cohort study to investigate psychological (cognitive and emotional) risk factors for CPSP after inguinal hernia surgery. Participants were asked to complete questionnaires before surgery and 1 week and 4 months after surgery. Data collected before surgery and 1 week after surgery were used to predict pain at 4 months. Psychological risk factors assessed included anxiety, depression, fear-avoidance, activity avoidance, catastrophizing, worry about the operation, activity expectations, perceived pain control and optimism. The study included 135 participants; follow-up questionnaires were returned by 119 (88.1%) and 115 (85.2%) participants at 1 week and 4 months after surgery respectively. The incidence of CPSP (pain at 4 months) was 39.5%. After controlling for age, body mass index and surgical variables (e.g. anaesthetic, type of surgery and mesh type used), lower pre-operative optimism was an independent risk factor for CPSP at 4 months; lower pre-operative optimism and lower perceived control over pain at 1 week after surgery predicted higher pain intensity at 4 months. No emotional variables were independently predictive of CPSP. Further research should target these cognitive variables in pre-operative psychological preparation for surgery. © 2011 European Federation of International Association for the Study of Pain Chapters.

Information and behavioural instruction along the health-care pathway:the perspective of people undergoing hernia repair surgery and the role of formal and informal information sources

Provision of information and behavioural instruction has been demonstrated to improve recovery after surgery. However, patients draw on a range of information sources and it is important to establish which sources patients use and how this influences perceptions and behaviour as they progress along the surgical pathway. In this qualitative, exploratory and longitudinal study, the use of information and instruction were explored from the perspective of people undergoing inguinal hernia repair surgery. Seven participants undergoing inguinal hernia repair surgery were interviewed using semi-structured interviews 2 weeks before surgery and 2 weeks and 4 months post-surgery. Nineteen interviews were conducted in total. Topic guides included sources of knowledge, reasons for help-seeking and opting for surgery and factors influencing return to activity. Data were analysed thematically according to Interpretative Phenomenological Analysis. Participants sought information from a range of sources, focusing on informal information sources before surgery and using information and instruction from health-care professionals post-surgery. This information influenced behaviours including deciding to undergo surgery, use of pain medication and returning to usual activity. Anxiety and help-seeking resulted when unexpected post-surgical events occurred such as extensive bruising. Findings were consistent with psychological and sociological theories. Overall, participants were positive about the information and instruction they received but expressed a desire for more timely information on post-operative adverse events.

Hernia perineal canina: reconstrucción del diafragma pélvico con malla de polipropileno a través de doble abordaje

La hernia perineal es una patología que se presenta en el macho de la especie canina de forma casi exclusiva, apareciendo de forma muy esporádica en la hembra y el gato, pero no se presenta en las otras especies domésticas. Se ha descrito en la especie humana sobre todo asociada a cirugías agresivas del abdomen caudal y siempre en relación a trastornos del suelo pélvico. En el perro la hernia perineal se produce por un fallo del diafragma pélvico, en el que destaca la atrofia y a veces la total desaparición del M. elevador de ano de forma uni- o bilateral. La debilidad-ausencia-desaparición de este músculo conduce a un posicionamiento más caudal de todos los órganos contenidos en el canal pélvico, vejiga, próstata, uretra post prostática, grasa periprostática y recto. Aparece en un rango muy amplio de edades aunque su tendencia más frecuente es alrededor de los 7-8 años de edad. Las manifestaciones clínicas de la hernia varían en función de la gravedad y antigüedad del proceso; el síntoma más frecuente es el estreñimiento y la deformación (tumefacción) de la fosa isquiática, pero se han descrito también la diarrea paradójica, vómitos y hasta la anuria obstructiva. La etiología de la hernia perineal esta poco clara, aunque existen diferentes hipótesis relacionadas con fenómenos que producen estreñimiento como hipertrofia prostática, o la existencia de quistes prostáticos y/o paraprostáticos. También se ha relacionado con saculitis o con la existencia de hernias inguinales. Otras teorías han relacionado la hernia con trastornos hormonales, desequilibrios entre receptores de andrógenos/estrógenos. Recientemente se la ha relacionado con la producción de relaxina en los quistes prostáticos y por último se la ha relacionado con alteraciones neurológicas del plexo pudendo. Pero lo cierto es que los porcentajes de perros con enfermedad prostática son muy altos sobre todo a partir de los 7- 8 años de edad y la incidencia de la hernia es muy baja. Tampoco todos los animales que padecen la hernia tienen quistes prostáticos y existen muchos animales con grandes quistes que no la desarrollan. En resumen, esta afección parece ser multifactorial aunque la lesión es siempre la misma, la debilidad progresiva del diafragma y la falta de funcionalismo hace el resto. Respecto a la cirugía ofrece también dificultades, se han descrito varias técnicas y las que mejores resultados ofrecen son las basadas en la elevación del obturador interno. No obstante en ocasiones este músculo también se encuentra atrofiado y la restauración del plano anatómico no es todo lo sólida que se desearía por lo cual se añade a la elevación del obturador, la utilización de mallas de polipropileno, la sobreposición del m. glúteo caudal, del músculo semitendinoso o la fijación intrabdominal de la vejiga, colon y conductos deferentes. A pesar de todo las recidivas siguen presentándose, aunque cada vez en menor porcentaje según las técnicas desarrolladas con posterioridad.

Minimally invasive repair of Morgagni hernia - A multicenter case series

Children may benefit from minimally invasive surgery (MIS) in the correction of Morgagni hernia (MH). The present study aims to evaluate the outcome of MIS through a multicenter study. National institutions that use MIS in the treatment of MH were included. Demographic, clinical and operative data were analyzed. Thirteen patients with MH (6 males) were operated using similar MIS technique (percutaneous stitches) at a mean age of 22.2±18.3 months. Six patients had chromosomopathies (46%), five with Down syndrome (39%). Respiratory complaints were the most common presentation (54%). Surgery lasted 95±23min. In none of the patients was the hernia sac removed; prosthesis was never used. In the immediate post-operative period, 4 patients (36%) were admitted to intensive care unit (all with Down syndrome); all patients started enteral feeds within the first 24h. With a mean follow-up of 56±16.6 months, there were two recurrences (18%) at the same institution, one of which was repaired with an absorbable suture; both with Down syndrome. The application of MIS in the MH repair is effective even in the presence of comorbidities such as Down syndrome; the latter influences the immediate postoperative recovery and possibly the recurrence rate. Removal of hernia sac does not seem necessary. Non-absorbable sutures may be more appropriate.

Dynamic self-regulating prosthesis in inguinal hernia repair

Inguinal hernia repair is one of the most common surgical procedure performed in Western countries and it consumes a lot of healthcare resources. Several types of different mesh are now disposable and tension-free techniques represent the “golden standard”. In our study, fifty male patients were operated on for inguinal hernia and a PAD (i.e., dynamic self-regulating prosthesis) used for the repair of the inguinal defect: this technique demonstrated to be safe, effective and easy to perform.

Modified patch repair of femoral hernia after inguinal herniorrhaphy

Background and aim. It has been reported that femoral hernias are rather common after a previous repair of inguinal hernia. We herein present a modified patch repair technique for large femoral hernias that develop after a Lichtenstein operation for ipsilateral inguinal hernia. Patients and methods. The modified technique for femoral hernia was applied to three patients who had a Lichtenstein repair for inguinal hernia. All patients were male. Hernia sac is dissected completely and sent back into to the preperitoneal space. Special attention should be given to the prevascular component of the sac. It is dissected as deep as possible into the preperitoneal space over the femoral vein. The defect is quite wide in this particular type of femoral hernia following Lichtenstein repair. A prosthetic patch that matches the defect is prepared. The medial edge of the mesh is configured to correspond to the pubic corner and lacunar ligament. The lateral margin of the patch is cut to create several petals for inverting the mesh above and medial to the femoral vein to prevent prevascular herniation. The mesh is secured to inguinal ligament, ilioinguinal tract, lacunar ligament, and Cooper ligament. Few sutures are put on the pubic corner and lacunar ligament. Results. One patient was discharged after two hours, other two stayed overnight. Readmission because of seroma development was recorded in two cases where standard polypropylene meshes were used. No complication was observed in the other patient who received lightweight meshes. No early recurrences were recorded after 4, 9, and 30 months. Conclusion. Femoral recurrence after previous inguinal hernia repair seems to be a specific entity. It has a prevascular component and the hernia defect can be much larger than that of a primary femoral hernia. A patch repair with infra-inguinal approach can be a valuable alternative with low complication rate.

Small bowel occlusion due to giant perineal hernia: abdominal approach with plastic perineal reconstruction

A perineal hernia is defined as a protrusion of peritoneal or extraperitoneal content through a pelvic floor defect. A 64-year-old woman with a bowel occlusions due to a giant postoperative perineal hernia was admitted to our hospital. We describe abdominal approach with plastic perineal reconstruction.

Incisional hernia in Day Surgery: our personal experience

Incisional hernia is one of the most common complications of laparotomy. Its repair with prosthesis has enabled a considerable improvement in the outcome, significantly reducing recurrences. This study analyses the results of open hernioplasty with mesh performed as a Day Surgery procedure in 42 patients between November 2008 and October 2010. The results were good, with low postoperative morbidity and recurrences (2.4%).
