RESUMEN
PURPOSE: The New England VA Hernia Registry was created in 2011 to prospectively collect relevant details of ventral hernia repairs, with the intention to assess and improve long term outcomes. The goal of this study is to assess registry compliance. METHODS: All ventral hernia operations performed in five VA hospitals between 2011-2022 were obtained. We assessed compliance at the hospital and surgeon level. RESULTS: 3,516 cases were performed. Overall compliance with registry entry was 37.5%, ranging from 10.8% to 67.2% across hospitals. At the hospital level, there was a negative correlation between average yearly hernia volume per surgeon and registry compliance (r2 = 0.53). Surgeon compliance varied within hospitals and over time. CONCLUSION: Registry compliance was low and highly variable. Lack of interest, incentives, oversight, and surgeon turnover are possible factors for noncompliance. Building a registry with these factors in mind, providing timely feedback, and conducting frequent audits may improve compliance.

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.

IMPORTANCE: The human and financial costs of treating surgical site infections (SSIs) are increasing. The number of surgical procedures performed in the United States continues to rise, and surgical patients are initially seen with increasingly complex comorbidities. It is estimated that approximately half of SSIs are deemed preventable using evidence-based strategies. OBJECTIVE: To provide new and updated evidence-based recommendations for the prevention of SSI. EVIDENCE REVIEW: A targeted systematic review of the literature was conducted in MEDLINE, EMBASE, CINAHL, and the Cochrane Library from 1998 through April 2014. A modified Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach was used to assess the quality of evidence and the strength of the resulting recommendation and to provide explicit links between them. Of 5759 titles and abstracts screened, 896 underwent full-text review by 2 independent reviewers. After exclusions, 170 studies were extracted into evidence tables, appraised, and synthesized. FINDINGS: Before surgery, patients should shower or bathe (full body) with soap (antimicrobial or nonantimicrobial) or an antiseptic agent on at least the night before the operative day. Antimicrobial prophylaxis should be administered only when indicated based on published clinical practice guidelines and timed such that a bactericidal concentration of the agents is established in the serum and tissues when the incision is made. In cesarean section procedures, antimicrobial prophylaxis should be administered before skin incision. Skin preparation in the operating room should be performed using an alcohol-based agent unless contraindicated. For clean and clean-contaminated procedures, additional prophylactic antimicrobial agent doses should not be administered after the surgical incision is closed in the operating room, even in the presence of a drain. Topical antimicrobial agents should not be applied to the surgical incision. During surgery, glycemic control should be implemented using blood glucose target levels less than 200 mg/dL, and normothermia should be maintained in all patients. Increased fraction of inspired oxygen should be administered during surgery and after extubation in the immediate postoperative period for patients with normal pulmonary function undergoing general anesthesia with endotracheal intubation. Transfusion of blood products should not be withheld from surgical patients as a means to prevent SSI. CONCLUSIONS AND RELEVANCE: This guideline is intended to provide new and updated evidence-based recommendations for the prevention of SSI and should be incorporated into comprehensive surgical quality improvement programs to improve patient safety.

INTRODUCTION: Hernia repairs in contaminated fields are often reinforced with a bioprosthetic mesh. When choosing which of the multiple musculofascial abdominal wall planes provides the most durable repair, there is little guidance. We hypothesized that the retro-rectus plane would reduce recurrence rates versus intraperitoneal placement due to greater surface area contact of mesh with well-vascularized tissue. METHODS: Forty-nine of the 80 patients in an ongoing, prospective, multicenter study of contaminated ventral hernia repairs (RICH study, NCT00617357) achieved fascial closure after musculofascial centralization and reinforcement with non-crosslinked porcine acellular dermal matrix (Strattice™, LifeCell, Branchburg, NJ) and were retrospectively analyzed. The Strattice was placed in the retro-rectus position in 23 patients and in the intraperitoneal position in 26. RESULTS: Subjects were comparable in age, obesity, prior wound infection, presence of a stoma, and infected mesh removal (p > 0.05). More smokers were present in the intraperitoneal group (p = 0.02). Retro-rectus defects were significantly wider and had larger area than the intraperitoneal repairs. At the 1-year follow-up, 44 (90%) of patients were available for review. There was no difference in wound infections, seromas, or hematomas. Recurrent hernias were identified in 10% of retro-rectus repairs and 30% of intraperitoneal repairs (p = 0.14). CONCLUSIONS: In this retrospective analysis of a prospective multicenter study of large, contaminated ventral hernias, despite a larger hernia defect in the retro-rectus group, placement of the mesh in the retro-rectus compartment resulted in a similar recurrence rate to intraperitoneal mesh placement. Ongoing evaluation is important to establish longer-term outcomes and the validity of these findings.

PURPOSE: Generic instruments used for the valuation of health states (e.g., EuroQol) often lack sensitivity to notable differences that are relevant to particular diseases or interventions. We developed a valuation methodology specifically for complications following ventral incisional herniorrhaphy (VIH). METHODS: Between 2004 and 2006, 146 patients were prospectively randomized to undergo laparoscopic (n = 73) or open (n = 73) VIH. The primary outcome of the trial was complications at 8 weeks. A three-step methodology was used to assign severity weights to complications. First, each complication was graded using the Clavien classification. Second, five reviewers were asked to independently and directly rate their perception of the severity of each class using a non-categorized visual analog scale. Zero represented an uncomplicated postoperative course, while 100 represented postoperative death. Third, the median, lowest, and highest values assigned to each class of complications were used to derive weighted complication scores for open and laparoscopic VIH. RESULTS: Open VIH had more complications than laparoscopic VIH (47.9 vs. 31.5%, respectively; P = 0.026). However, complications of laparoscopic VIH were more severe than those of open VIH. Non-parametric analysis revealed a statistically higher weighted complication score for open VIH (interquartile range: 0-20 for open vs. 0-10 for laparoscopic; P = 0.049). In the sensitivity analysis, similar results were obtained using the median, highest, and lowest weights. CONCLUSION: We describe a new methodology for the valuation of complications following VIH that allows a direct outcome comparison of procedures with different complication profiles. Further testing of the validity, reliability, and generalizability of this method is warranted.
