Reperfused human cadaver as a new simulation model for colonoscopy: a pilot study.

BACKGROUND: The reperfused human cadaver is a validated simulator for surgery. We aimed to use it as a colonoscopy simulator. METHODS: Novices, intermediates and skilled participants in gastrointestinal endoscopy were included. They performed one colonoscopy on a reperfused human cadaver and reaching rates, time, and length needed to reach anatomical landmarks were reported for construct validity analysis. We also assessed our model realism (SRS survey), educational content (CVS survey) and task load (NASA-TLX index). Score items were collected and defined as "favorable" when items were rated ≥ 5/7 with an inter-quartile range (IQR) overlapping four, and "very favorable" when rated ≥ 5/7 with an IQR excluding four (neutral). Primary endpoints were the rectosigmoid junction (RSJ) reaching rate and the descending colon (DC) reaching time. Secondary objectives were SRS, CVS and NASA-TLX questionnaire results. RESULTS: A total of 11 skilled participants, 5 intermediates and 8 novices were included. Skilled participants reached RSJ more often than novice and intermediary groups, respectively, 100%, 80% and 75% without differing significantly. They reached DC more frequently (100% for skilled, 80% for intermediates and 50% for novices, p = 0.018). The median time to reach RSJ (59, 272 and 686 s for skilled, intermediates and novices group, respectively) and DC (90, 534 and 1360 s for skilled, intermediates and novices) was significantly shorter for skilled participants (both p < .01). Nineteen out of the 22 items composing the realism survey obtained "very favorable" and "favorable" scores. Educational content was designated as "very favorable". Mental, physical, and technical demands were gradually higher the lower the initial level of experience. CONCLUSIONS: Reperfused human cadaver model has the potential to be valid simulation tool for diagnostic colonoscopy training.

Reporting guideline for interventional trials of primary and incisional ventral hernia repair.

BACKGROUND: Primary and incisional ventral hernia trials collect unstandardized inconsistent data, limiting data interpretation and comparison. This study aimed to create two minimum data sets for primary and incisional ventral hernia interventional trials to standardize data collection and improve trial comparison. To support these data sets, standardized patient-reported outcome measures and trial methodology criteria were created. METHODS: To construct these data sets, nominal group technique methodology was employed, involving 15 internationally recognized abdominal wall surgeons and two patient representatives. Initially a maximum data set was created from previous systematic and panellist reviews. Thereafter, three stages of voting took place: stage 1, selection of the number of variables for data set inclusion; stage 2, selection of variables to be included; and stage 3, selection of variable definitions and detection methods. A steering committee interpreted and analysed the data. RESULTS: The maximum data set contained 245 variables. The three stages of voting commenced in October 2019 and had been completed by July 2020. The final primary ventral hernia data set included 32 variables, the incisional ventral hernia data set included 40 variables, the patient-reported outcome measures tool contained 25 questions, and 40 methodological criteria were chosen. The best known variable definitions were selected for accurate variable description. CT was selected as the optimal preoperative descriptor of hernia morphology. Standardized follow-up at 30 days, 1 year, and 5 years was selected. CONCLUSION: These minimum data sets, patient-reported outcome measures, and methodological criteria have allowed creation of a manual for investigators aiming to undertake primary ventral hernia or incisional ventral hernia interventional trials. Adopting these data sets will improve trial methods and comparisons.

Guidelines for treatment of umbilical and epigastric hernias from the European Hernia Society and Americas Hernia Society.

BACKGROUND: Umbilical and epigastric hernia repairs are frequently performed surgical procedures with an expected low complication rate. Nevertheless, the optimal method of repair with best short- and long-term outcomes remains debatable. The aim was to develop guidelines for the treatment of umbilical and epigastric hernias. METHODS: The guideline group consisted of surgeons from Europe and North America including members from the European Hernia Society and the Americas Hernia Society. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach, the Scottish Intercollegiate Guidelines Network (SIGN) critical appraisal checklists, and the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument were used. A systematic literature search was done on 1 May 2018, and updated on 1 February 2019. RESULTS: Literature reporting specifically on umbilical and epigastric hernias was limited in quantity and quality, resulting in a majority of the recommendations being graded as weak, based on low-quality evidence. The main recommendation was to use mesh for repair of umbilical and epigastric hernias to reduce the recurrence rate. Most umbilical and epigastric hernias may be repaired by an open approach with a preperitoneal flat mesh. A laparoscopic approach may be considered if the hernia defect is large, or if the patient has an increased risk of wound morbidity. CONCLUSION: This is the first European and American guideline on the treatment of umbilical and epigastric hernias. It is recommended that symptomatic umbilical and epigastric hernias are repaired by an open approach with a preperitoneal flat mesh.

ANTECEDENTES: La reparación de las hernias umbilicales y epigástricas es un procedimiento quirúrgico frecuente con una tasa esperada de complicaciones baja. Sin embargo, sigue en discusión cuál es el mejor método de reparación óptimo para obtener los mejores resultados a corto y a largo plazo. El objetivo del estudio fue desarrollar una guía para el tratamiento de las hernias umbilicales y epigástricas. MÉTODOS: El grupo para la elaboración de la guía estuvo formado por cirujanos europeos y norteamericanos junto con miembros de la European Hernia Society (EHS) y de la America's Hernia Society (AHS). Para elaborar la guía, se siguieron las recomendaciones GRADE (Grading of Recommendations Assessment, Development and Evaluation), SIGN (Scottish Intercollegiate Guidelines Network) y AGREE (Appraisal of Guidelines for Research & Evaluation). Se realizó una búsqueda sistemática de la literatura el 1 de mayo de 2018, que luego se actualizó el 1 de febrero de 2019. RESULTADOS: Los trabajos dedicados de forma específica a las hernias umbilicales y epigástricas eran muy limitados en cantidad y calidad, por lo que la mayoría de las recomendaciones que se extrajeron fueron calificadas como débiles y basadas en una baja calidad de la evidencia. La recomendación principal era utilizar una malla en la reparación de las hernias umbilicales y epigástricas para reducir la tasa de recidiva. La mayoría de las hernias umbilicales y epigástricas pueden repararse mediante un abordaje abierto con una malla plana preperitoneal. Se puede considerar el abordaje laparoscópico si el defecto de la hernia es grande o si el paciente tiene un riesgo aumentado de morbilidad de la herida. CONCLUSIÓN: Esta es la primera guía europea y americana del tratamiento de las hernias umbilicales y epigástricas. Se sugiere reparar las hernias sintomáticas umbilicales y epigástricas mediante un abordaje abierto con una malla plana preperitoneal.

International classification of abdominal wall planes (ICAP) to describe mesh insertion for ventral hernia repair.

BACKGROUND: Nomenclature for mesh insertion during ventral hernia repair is inconsistent and confusing. Several terms, including 'inlay', 'sublay' and 'underlay', can refer to the same anatomical planes in the indexed literature. This frustrates comparisons of surgical practice and may invalidate meta-analyses comparing surgical outcomes. The aim of this study was to establish an international classification of abdominal wall planes. METHODS: A Delphi study was conducted involving 20 internationally recognized abdominal wall surgeons. Different terms describing anterior abdominal wall planes were identified via literature review and expert consensus. The initial list comprised 59 possible terms. Panellists completed a questionnaire that suggested a list of options for individual abdominal wall planes. Consensus on a term was predefined as occurring if selected by at least 80 per cent of panellists. Terms scoring less than 20 per cent were removed. RESULTS: Voting started August 2018 and was completed by January 2019. In round 1, 43 terms (73 per cent) were selected by less than 20 per cent of panellists and 37 new terms were suggested, leaving 53 terms for round 2. Four planes reached consensus in round 2, with the terms 'onlay', 'inlay', 'preperitoneal' and 'intraperitoneal'. Thirty-five terms (66 per cent) were selected by less than 20 per cent of panellists and were removed. After round 3, consensus was achieved for 'anterectus', 'interoblique', 'retro-oblique' and 'retromuscular'. Default consensus was achieved for the 'retrorectus' and 'transversalis fascial' planes. CONCLUSION: Consensus concerning abdominal wall planes was agreed by 20 internationally recognized surgeons. Adoption should improve communication and comparison among surgeons and research studies.

ANTECEDENTES: La nomenclatura de la inserción de una malla para la reparación de una hernia incisional ventral (ventral hernia, VH) es inconsistente y confusa. En la literatura indexada se usan varios términos, tales como 'inlay', 'sublay', y 'underlay' que pueden referirse a los mismos planos anatómicos. Este hecho frustra las comparaciones de técnicas quirúrgicas e invalida los metaanálisis que comparan resultados quirúrgicos en función del plano de inserción de la malla. En consecuencia, el objetivo de este estudio fue establecer una clasificación internacional de los planos de la pared abdominal (International Classification of Abdominal Wall Planes, ICAP). MÉTODOS: Se realizó un estudio Delphi, en el que participaron 20 cirujanos de pared abdominal reconocidos internacionalmente. Se identificaron diferentes términos que describían los planos de la pared abdominal anterior mediante la revisión de la literatura y el consenso de expertos. La lista inicial incluía 59 términos posibles. Los panelistas completaron un cuestionario que sugería una lista de opciones para los planos individuales de la pared abdominal. El consenso sobre un término fue predefinido cuando dicho término había sido seleccionado por ≥ 80% de panelistas. Se eliminaron los términos con una puntuación < 20%. RESULTADOS: La votación comenzó en agosto de 2018 y se completó en enero de 2019. Durante la Ronda 1, 43 (73%) términos fueron seleccionados por < 20% de los panelistas y se sugirieron 37 términos nuevos, dejando 53 términos para la Ronda 2. Cuatro planos alcanzaron un consenso en la Ronda 2 con los términos 'onlay', 'inlay', 'pre-peritoneal' e 'intra-peritoneal'. Treinta y cinco (66%) términos fueron seleccionados por < 20% de los panelistas y fueron eliminados. Después de la Ronda 3, se logró un consenso para 'anterectus' (ante-recto), 'interoblique' (inter-oblicuo), 'retrooblique' (retro-oblicuo) y 'retromuscular'. Se alcanzó un consenso por defecto para los planos 'retrorectus' (retro-recto) y 'transversalis fascial' (fascial transverso). CONCLUSIÓN: La ICAP ha sido desarrollada por el consenso de 20 cirujanos reconocidos internacionalmente. Su implementación debería mejorar la comunicación y la comparación entre cirujanos y estudios de investigación.

[Is sarcopenia a morbi-mortality factor in the treatment of localized muscle-invasive bladder cancer?] / La sarcopénie est-elle un facteur de morbi-mortalité dans le traitement des tumeurs localisées de la vessie infiltrant le muscle ?

INTRODUCTION: Sarcopenia evaluated from the measurement of skeletal muscle index (SMI) has been evaluated as a predictive factor of morbidity and mortality after surgery. The objective of this study was to evaluate whether it was predictive of morbidity and mortality in patients managed by cystectomy or tri-modality therapy (TMT), combining radiotherapy and chemotherapy after endoscopic resection of the tumour, for localized muscle-invasive bladder cancer. MATERIALS AND METHODS: In all, 146 consecutive patients from 2 university hospital centres treated by cystectomy between January 2012 and April 2017 or TMT between October 2008 and October 2014 were included. The SMI was measured on axial computed-tomography at the level of the transverse process of L3, before treatment. Sarcopenia was assessed in two ways: either by SMI without muscle mass adjustment or according to the definition by Martin and al. based on gender and patient BMI, then called "adjusted sarcopenia". The primary endpoint was overall survival (OS) for sarcopenia. The secondary endpoints were OS, progression-free survival (PFS) and survival without re-admission (SRH) for the total population and for each treatment group. Survival analyses were performed using the Cox model. The association between sarcopenia and complications has been investigated by the Chi2 test. RESULTS: The characteristics of sarcopenic (n=67) and non-sarcopenic (n=79) patients were comparable except for 2 criteria: older patients in the sarcopenic group and a higher proportion of neo-adjuvant chemotherapy in non-sarcopenic patients. Sarcopenia was not significantly associated with any type of survival. Sarcopenia was not associated with the proportion or severity of complications. CONCLUSION: Unlike unadjusted SMI, sarcopenia was not associated with survival or complications. LEVEL OF EVIDENCE: 3.

[Symptomatic lumbar incisional hernia after open nephrectomy: What are the risk factors?]. / Éventrations lombaires symptomatiques après néphrectomies par lombotomie: quels sont les facteurs de risque?

OBJECTIVE: Lumbar incisional hernias after open nephrectomy are rare but can lead to aesthetic disorder, discomfort or intestinal obstruction. The aim of the study is to highlight their risk factors. PATIENTS AND METHODS: The characteristics of patients who suffered from symptomatic and surgically treated lumbar incisionnal hernia after open nephrectomy (study group "GE") were compared to those of patients who underwent open nephrectomy without postoperative incisional hernia (control group "GT") using the Student's t test and Mann-Whitney test (statistical significance P value<0.05). GT patients were randomly selected with a 1/4 ratio (1 lumbar incisionnal hernia vs 4 controls). RESULTS: From 2004 to 2014, 417 open nephrectomies were performed in one university hospital. Forty-five patients were included: 9 in GE and 36 in GT. There was no statistically significant difference between GT and GE for weight, height, body mass index (BMI), emergency, partial nephrectomy, laterality, rib resection, laparoscopic conversion to open surgery, postoperative complications, smoking, diabetes mellitus, cardiovascular history, obesity and sex, but there was a statistically significant difference for age, operative time, chronic obstructive pulmonary disease (COPD) and severe obesity (BMI>35) with, respectively, P=0.05, P=0.02, P=0.04 and P=0.02. CONCLUSION: Risk factors for lumbar incisional hernia after open nephrectomy are age, operative time, severe obesity and COPD. LEVEL OF EVIDENCE: 5.

A review of corporate sustainability reporting tools (SRTs).

Sustainability reporting has been increasingly adopted by corporations worldwide given the demand of stakeholders for greater transparency on both environmental and social issues. The popularity of such reporting is evidenced by the development of a range of tools in the last two decades - Global Reporting Initiative (GRI), AA1000 and Carbon Disclosure Project (CDP) inter alia. These tools, referred to collectively as corporate sustainability reporting tools (SRTs) are important as they serve to inform the progress of corporations towards achieving sustainability goals. However, the rapid growth of corporate SRTs, with different criteria and methodology has created major complications for stakeholders. This paper makes a genuine contribution by providing a review of some of these major tools, spanning across a wide spectrum - framework, standards, ratings and indices. A critique of SRTs is also given. Institutional investors, governments, practitioners and individuals may find this review useful in terms of understanding the nature of different corporate SRTs. As well, it can serve as a useful reference for the development of the next generation of corporate SRTs.

Delphi consensus statement for understanding and managing the subcostal hernia: subcostal hernias collaborative report (scholar study).

INTRODUCTION: Subcostal hernias are categorized as L1 based on the European Hernia Society (EHS) classification and frequently involve M1, M2, and L2 sites. These are common after hepatopancreatic and biliary surgeries. The literature on subcostal hernias mostly comprises of retrospective reviews of small heterogenous cohorts, unsurprisingly leading to no consensus or guidelines. Given the limited literature and lack of consensus or guidelines for dealing with these hernias, we planned for a Delphi consensus to aid in decision making to repair subcostal hernias. METHODS: We adopted a modified Delphi technique to establish consensus regarding the definition, characteristics, and surgical aspects of managing subcostal hernias (SCH). It was a four-phase Delphi study reflecting the widely accepted model, consisting of: 1. Creating a query. 2. Building an expert panel. 3. Executing the Delphi rounds. 4. Analysing, presenting, and reporting the Delphi results. More than 70% of agreement was defined as a consensus statement. RESULTS: The 22 experts who agreed to participate in this Delphi process for Subcostal Hernias (SCH) comprised 7 UK surgeons, 6 mainland European surgeons, 4 Indians, 3 from the USA, and 2 from Southeast Asia. This Delphi study on subcostal hernias achieved consensus on the following areas-use of mesh in elective cases; the retromuscular position with strong discouragement for onlay mesh; use of macroporous medium-weight polypropylene mesh; use of the subcostal incision over midline incision if there is no previous midline incision; TAR over ACST; defect closure where MAS is used; transverse suturing over vertical suturing for closure of circular defects; and use of peritoneal flap when necessary. CONCLUSION: This Delphi consensus defines subcostal hernias and gives insight into the consensus for incision, dissection plane, mesh placement, mesh type, and mesh fixation for these hernias.

Incidence, risk factors, and burden of incisional hernia repair after abdominal surgery in France: a nationwide study.

PURPOSE: Incisional hernias are common after laparotomies. The aims of this study were to assess the rate of incisional hernia repair after abdominal surgery, recurrence rate, hospital costs, and risk factors, in France. METHODS: This national, retrospective, longitudinal, observational study was based on the exhaustive hospital discharge database (PMSI). All adult patients (≥ 18 years old) hospitalised for an abdominal surgical procedure between 01-01-2013 and 31-12-2014 and hospitalised for incisional hernia repair within five years were included. Descriptive analyses and cost analyses from the National Health Insurance (NHI) viewpoint (hospital care for the hernia repair) were performed. To identify risk factors for hernia repair a multivariable Cox model and a machine learning analysis were performed. RESULTS: In 2013-2014, 710074 patients underwent abdominal surgery, of which 32633 (4.6%) and 5117 (0.7%) had ≥ 1 and ≥ 2 incisional hernia repair(s) within five years, respectively. Mean hospital costs amounted to €4153/hernia repair, representing nearly €67.7 million/year. Some surgical sites exposed patients at high risk of incisional hernia repair: colon and rectum (hazard ratio [HR] 1.2), and other sites on the small bowel and the peritoneum (HR 1.4). Laparotomy procedure and being ≥ 40 years old put patients at high risk of incisional hernia repair even when operated on low-risk sites such as stomach, duodenum, and hepatobiliary. CONCLUSION: The burden of incisional hernia repair is high and most patients are at risk either due to age ≥ 40 or the surgery site. New approaches to prevent the onset of incisional hernia are warranted.

Incisional hernia repair with a slowly absorbable P4HB mesh: what happens after the mesh disappears? A retrospective longitudinal clinical study.

PURPOSE: To analyze the incisional hernia recurrence rate at a long-term follow-up using a biosynthetic long-term absorbable mesh in patients with a higher risk of surgical infection in a contaminated surgical field. METHODS: This was a retrospective multicentric study. All patients undergoing incisional hernia repair between 2016 and 2018 at 6 participating university centers were included. Patients were classified according to the Ventral Hernia Working Group (VHWG). All consecutive patients who underwent abdominal wall repair using biosynthetic long-term absorbable mesh (Phasix®) in contaminated fields (grade 3 and 4 of the VHWG classification) were included. Patients were followed-up until September 2021. Preoperative, operative, and postoperative data were collected. All patients' surgical site infections (SSIs) and surgical site occurrences (SSOs) were recorded. The primary outcome of interest was the clinical incisional hernia recurrence rate. RESULTS: One hundred and eight patients were included: 77 with VHWG grade 3 (71.3%) and 31 with VHWG grade 4 (28.7%). Median time follow-up was 41 months [24; 63]. Twenty-four patients had clinical recurrence during the follow-up (22.2%). The SSI and SSO rates were 24.1% and 36.1%, respectively. On multivariate analysis, risk factors for incisional hernia recurrence were previous recurrence, mesh location, and postoperative enterocutaneous fistula. CONCLUSIONS: At the 3 year follow-up, the recurrence rate with a biosynthetic absorbable mesh (Phasix®) for incisional hernia repair in high-risk patients (VHWG grade 3 and 4) seemed to be suitable (22.2%). Most complications occurred in the first year, and SSI and SSO rates were low despite high-risk VHWG grading.

Adjunct botox to preoperative progressive pneumoperitoneum for incisional hernia with loss of domain: no additional effect but may improve outcomes.

INTRODUCTION: Incisional hernia with loss of domain (IHLD) remains a surgical challenge. Its management requires complex approaches including specific preoperative and intra-operative techniques. This study focuses on the interest of adding preoperative botulinum toxin A (BTA) injection to preoperative progressive pneumoperitoneum (PPP), compared to PPP alone. MATERIAL: Patients between January 2015 and March 2020 with IHLD who underwent pre-operative preparation were included. Their baseline characteristics were retrospectively analyzed, along with the characteristics of their incisional hernia before and after preparation including CT-scan volumetry. Intra-operative data, early post-operative outcomes, surgical site occurrences (SSOs) including surgical site infection (SSI) were recorded. RESULTS: Four hundred and fifty (450) patients with incisional hernia were operated, including 41 patients (9.1%) with IHLD, 13 of which had both BTA and PPP, while 28 had PPP only. Both groups were comparable in term of patients and IHLD characteristics. Median increase in the volume of the abdominal cavity (VAbC) was + 55% for the entire population (+ 58.3% for the BTA-PPP group, p < 0.0001 and + 52.8% for the PPP-alone group, p < 0.0001) although the increase in volume was not different between the two groups (p = 0.99). Complete fascial closure was achieved in all patients. SSOs were more frequent in the PPP-alone group than in the BTA-PPP group (17 (60.7%) versus 3 (23.1%) patients, respectively, p = 0.043). CONCLUSION: BTA and PPP are both useful in pre-operative preparation for IHLD. Combining both significantly increases the volume of abdominal cavity but associating BTA to PPP does not add any volumetric benefit but may decrease the post-operative SSO rate.

Slowly absorbable mesh in contaminated incisional hernia repair: results of a French multicenter study.

PURPOSE: To analyze the postoperative morbidity and 1-year recurrence rate of incisional hernia repair using a biosynthetic long-term absorbable mesh in patients at higher risk of surgical infection in a contaminated surgical field. METHODS: All patients undergoing incisional hernia repair in a contaminated surgical field with the use of a biosynthetic long-term absorbable mesh (Phasix®) between May 2016 and September 2018 at six participating university centers were included in this retrospective cohort and were followed-up until September 2019. Regarding the risk of surgical infection, patients were classified according to the modified Ventral Hernia Working Group classification. Preoperative, operative and postoperative data were collected. All patients' surgical site infections (SSIs) and occurrences (SSOs) and recurrence rates were the endpoints of the study. RESULTS: Two hundred and fifteen patients were included: 170 with mVHWG grade 3 (79%) and 45 with mVHWG grade 2 (21%). The SSI and SSO rates at 12 months were 22.3% and 39.5%, respectively. According to the Dindo-Clavien classification, 43 patients (20.0%) had at least one minor complication, and 57 patients (26.5%) had at least one major complication. Among the 121 patients (56.3%) having at least 1 year of follow-up, the clinical recurrence rate was 12.4%. Multivariate analysis showed that a concomitant gastrointestinal procedure was an independent risk factor for surgical infection (OR = 2.61), and an emergency setting was an independent risk factor for major complications (OR = 11.9). CONCLUSION: The use of a biosynthetic absorbable mesh (Phasix®) is safe in a contaminated surgical field, with satisfying immediate postoperative and 1-year results. TRIAL REGISTRATION: The study is registered on Clinical Trial ID: NCT04132986.

EHS and AHS guidelines for treatment of primary ventral hernias in rare locations or special circumstances.

BACKGROUND: Rare locations of hernias, as well as primary ventral hernias under certain circumstances (cirrhosis, dialysis, rectus diastasis, subsequent pregnancy), might be technically challenging. The aim was to identify situations where the treatment strategy might deviate from routine management. METHODS: The guideline group consisted of surgeons from the European and Americas Hernia Societies. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used in formulating the recommendations. The Scottish Intercollegiate Guidelines Network (SIGN) critical appraisal checklists were used to evaluate the quality of full-text papers. A systematic literature search was performed on 1 May 2018 and updated 1 February 2019. The Appraisal of Guidelines for Research and Evaluation (AGREE) instrument was followed. RESULTS: Literature was limited in quantity and quality. A majority of the recommendations were graded as weak, based on low quality of evidence. In patients with cirrhosis or on dialysis, a preperitoneal mesh repair is suggested. Subsequent pregnancy is a risk factor for recurrence. Repair should be postponed until after the last pregnancy. For patients with a concomitant rectus diastasis or those with a Spigelian or lumbar hernia, no recommendation could be made for treatment strategy owing to lack of evidence. CONCLUSION: This is the first European and American guideline on the treatment of umbilical and epigastric hernias in patients with special conditions, including Spigelian and lumbar hernias. All recommendations were weak owing to a lack of evidence. Further studies are needed on patients with rectus diastasis, Spigelian and lumbar hernias.

ANTECEDENTES: Las hernias de localización rara, así como las hernias ventrales primarias en determinadas circunstancias (cirrosis, diálisis, diástasis de recto, tras un embarazo) pueden ser complejas desde el punto de vista técnico. El objetivo fue identificar situaciones en las que la estrategia de tratamiento pudiera ser diferente del tratamiento habitual. MÉTODOS: Esta guía fue elaborada por cirujanos de las sociedades europeas y americana de hernia (European Hernia Society, EHS y American Hernia Society, AHS). La búsqueda sistemática de la literatura se efectuó el 1 de mayo de 2018 y se actualizó el 1 de febrero de 2019. Para evaluar la calidad de los artículos completos seleccionados se utilizó la normativa SIGN (Scottish Intercollegiate Guidelines Network). Las recomendaciones formuladas siguieron la metodología GRADE (Grading of Recommendations Assessment, Development and Evaluation) y la redacción de la guía siguió las normas AGREE (Appraisal of Guidelines for Research & Evaluation). RESULTADOS: La literatura es limitada en cantidad y calidad. La mayoría de las recomendaciones se calificaron como débiles en función de la baja calidad de la evidencia. En pacientes con cirrosis o en diálisis, se sugiere una reparación con malla preperitoneal. Un embarazo tras la reparación de una hernia es un factor de riesgo de recidiva. La reparación debería posponerse hasta después del último embarazo. Debido a la falta de evidencia no se pudo hacer ninguna recomendación para la reparación de hernias en pacientes con diástasis de recto concomitante o con hernias de Spigel o lumbares. CONCLUSIÓN: Esta es la primera guía europea y americana del tratamiento de hernias umbilicales y epigástricas en pacientes con patologías especiales, incluyendo las hernias de Spigel y lumbares. Todas las recomendaciones fueron débiles debido a la falta de evidencia. Se necesitan más estudios en pacientes con diástasis de recto, hernias de Spigel y lumbares.

Medical Infrared Thermography assistance in the surgical treatment of axillary Hidradenitis Suppurativa: A case report.

BACKGROUND: The purpose of this case report is to highlight for the first time the way Medical Infrared Thermography can be a helpful tool to assist the surgeon in the surgical treatment of Hidradenitis Suppurativa inflammatory disease. METHODS: A 36-year-old man with a 7-year history of Hidradenitis Suppurativa presented inflammatory nodules in the left axilla area corresponding to Hurley stage II. Choice is made to surgically treat this patient using a wide excision protocol combined with a postoperative second intention healing. For the study purpose, an IR FLIR SC620 camera (FLIR Systems, Wilsonville, OR), having a high resolution pixel detector of 640×480 pixels for greater accuracy and higher resolution, has been used. RESULTS: For the first time in the literature, this case report on HS disease supports the idea that real-time medical infrared thermography may be helpful in establishing the true extent of disease preoperatively in the surgical room and in a similar manner, that this technique allows the surgeon to ensure all diseased lesions are removed during surgery. CONCLUSIONS: At least, medical infrared thermography seems to be a powerful tool to control the final wide surgical wound, in order to minimize recurrence risk of such a disease.

Open retromuscular large mesh reconstruction of lumbar incisional hernias including the atrophic muscular area.

PURPOSE: Lumbar incisional hernias (LIH) are a rare wall defect, whose surgical management is challenging because no recommendation exists. Moreover, LIH are frequently associated with flank bulging which should be taken into account during LIH surgical repair. We aimed to describe a cohort of patients operated on for LIH using a homogeneous surgical technique and to report surgical outcomes. METHODS: The records of all consecutive patients operated on in a specialized surgical center between January 2009 and January 2015 were retrospectively reviewed. The same open technique was performed, i.e., using a mesh into the retroperitoneal space posteriorly, placed with the largest overlap inferiorly and posteriorly, and fixed through the controlateral abdominal wall muscles under strong tension to correct the flank bulging. RESULTS: The cohort included 31 patients, of median age 62, who presented two or more comorbidities in 68% of cases. LIH was recurrent in 45% of patients, and was related to nephrectomy in 61% of patients. The mesh was totally extraperitoneal in 65% of patients. The postoperative mortality rate was null. The rate of specific surgical complications was 32.3%, and the rate of overall postoperative morbidity (Clavien-Dindo classification) was 38.7%. After a median follow-up of 27.5 months, the recurrence rate was 6.5% and 9.7% reported chronic pain. CONCLUSION: The open approach for LIH repair was safe and enabled treating flank bulging simultaneously in all patients. Due to the paucity of adequate scientific studies, this reproducible open method could help moving toward a standardization of LIH surgical management.

[Preventive treatment using laser of age-related macular degeneration of the contralateral eye after age-related macular degeneration of the first eye]. / Traitement prophylactique par laser de la DMLA de l'oeil adelphe après DMLA du premier oeil.

Since 1982, and with informed patient consent, we have photocoagulated confluent drusen and limited serous pigment epithelium detachment (SPED) in the fellow eye of ten patients suffering from advanced, disciform type, age-related macula degeneration (ARMD). This treatment was only carried out on appearance of metamorphopsia. Photocoagulation was performed with either the green ray of the argon laser, or the yellow ray of a dye laser. Spots of about 200 microns were placed in a grid-like fashion among the drusen. No complications were observed due to the treatment. The follow-up period on these ten patients, eight women and two men, mean age 77 years, was two to eight years, and the three patients have died. The drusen disappeared completely in three patients and partially in one. The functional results seemed favorable in three cases. In one case of confluent drusen associated with SPED and serous retinal detachment, vision improved remarkably from 0.3 to 0.5 with a Parinaud 2, with a follow-up of five years. In another case, the improvement was from 0.4 to 0.7 but the patient died after only a few months. In another case, vision has been stable for five years. The vision of the seven remaining patients deteriorated; three cases showed central areolar sclerosis, and one case a localised new vessel with vision less than 0.1. In three cases vision dropped to 0.2 and Parinaud 6, but they have been stable for at least four years (eight years for one patient).(ABSTRACT TRUNCATED AT 250 WORDS)

[Long-term results of successful surgical treatment of retinal detachment by vitrectomy and silicone oil injection. Effect of removal of the tamponade on further complications]. / Evolution à long terme des yeux opérés avec succès de décollement de rétine par vitrectomie et injection d'huile de silicone. Effet de l'ablation du tamponnement sur les complications.

We present, with a minimal follow up of six months, the results of 118 silicone oil removals following successful treatment of retinal detachment by pars plana vitrectomy and silicone oil injection. A recurrent retinal detachment occurred in 8.5% of cases, 13% of the 61 phakic eyes at the time of silicone oil removal maintained a clear lens, 29.6% of the eyes had a raised intraocular pressure and 6.8% had a keratopathy. The visual acuity improved in 72.8% of eyes after silicone oil removal. The main reasons for a late decrease in visual acuity were recurrence of the detachment, hypertonia, chronic hypotonia and keratopathy. All the eyes with late complications after silicone oil removal had a clinically significant droplet dispersion in the anterior chamber. Only complete and early silicone oil removal seems to decrease the complication rate.
