Hohlraum Reheating from Burning NIF Implosions.

As fusion experiments at the National Ignition Facility (NIF) approach and exceed breakeven, energy from the burning capsule is predicted to couple to the gold walls and reheat the hohlraum. On December 5, 2022, experiment N221204 exceeded target breakeven, historically achieving 3.15 MJ of fusion energy from 2.05 MJ of laser drive; for the first time, energy from the igniting capsule reheated the hohlraum beyond the peak laser-driven radiation temperature of 313 eV to a peak of 350 eV, in less than half a nanosecond. This reheating effect has now been unambiguously observed by the two independent Dante calorimeter systems across multiple experiments, and is shown to result from reheating of the remnant tungsten-doped ablator by the exploding core, which is heated by alpha deposition.

A synopsis of global frontiers in fertility preservation.

Since 2007, the Oncofertility Consortium Annual Conference has brought together a diverse network of individuals from a wide range of backgrounds and professional levels to disseminate emerging basic and clinical research findings in fertility preservation. This network also developed enduring educational materials to accelerate the pace and quality of field-wide scientific communication. Between 2007 and 2019, the Oncofertility Consortium Annual Conference was held as an in-person event in Chicago, IL. The conference attracted approximately 250 attendees each year representing 20 countries around the world. In 2020, however, the COVID-19 pandemic disrupted this paradigm and precluded an in-person meeting. Nevertheless, there remained an undeniable demand for the oncofertility community to convene. To maintain the momentum of the field, the Oncofertility Consortium hosted a day-long virtual meeting on March 5, 2021, with the theme of "Oncofertility Around the Globe" to highlight the diversity of clinical care and translational research that is ongoing around the world in this discipline. This virtual meeting was hosted using the vFairs ® conference platform and allowed over 700 people to participate, many of whom were first-time conference attendees. The agenda featured concurrent sessions from presenters in six continents which provided attendees a complete overview of the field and furthered our mission to create a global community of oncofertility practice. This paper provides a synopsis of talks delivered at this event and highlights the new advances and frontiers in the fields of oncofertility and fertility preservation around the globe from clinical practice and patient-centered efforts to translational research.

Intraperitoneal versus retromuscular mesh placement for open incisional hernias: an analysis of the Americas Hernia Society Quality Collaborative.

BACKGROUND: Incisional hernia repair with mesh improves long-term outcomes, but the ideal mesh position remains unclear. This study compared intraperitoneal versus retromuscular or preperitoneal sublay (RPS) mesh positions for open incisional hernia repairs. METHODS: All patients who had elective open incisional hernia repairs were identified retrospectively in the Americas Hernia Society Quality Collaborative database. The primary outcome was the rate of 30-day surgical-site infection (SSI). Other outcomes of interest included 30-day surgical-site occurrences requiring procedural intervention (SSOPI), hernia-related quality-of-life survey (HerQLes) scores and long-term recurrence. A logistic model was used to generate propensity scores for mesh position using several clinically relevant co-variables. Regression models adjusting for propensity score and baseline characteristics were developed to assess the effect of mesh placement. RESULTS: A total of 4211 patients were included in the study population: 587 had intraperitoneal mesh and 3624 had RPS mesh. Analysis with propensity score adjustment provided no evidence for differences in SSOPI (odds ratio (OR) 0·79, 95 per cent c.i. 0·49 to 1·26) and SSI (OR 0·91, 0·50 to 1·67) rates or HerQLes scores at 30 days (OR 1·20, 0·79 to 1·82), or recurrence rates (hazard ratio 1·28, 0·90 to 1·82). CONCLUSION: Mesh position had no effect on short- or long-term outcomes, including SSOPI and SSI rates, HerQLes scores and long-term recurrence rates.

ANTECEDENTES: La reparación de una eventración con malla mejora los resultados a largo plazo, pero sigue sin estar definida cuál es la posición ideal de colocación de la malla. Este estudio comparó los resultados de la reparación abierta de una eventración con malla en posición intraperitoneal versus retromuscular o preperitoneal (retromuscular or preperitoneal sublay, RPS). MÉTODOS: Se identificaron de forma retrospectiva todos los pacientes a los que se reparó una eventración por via abierta en el Americas Hernia Society Quality Collaborative. La variable principal fue la tasa de infección de la herida quirúrgica (surgical site infections, SSI) a los 30 días. Se analizaron también las incidencias acaecidas en la herida que hubieran precisado algún tratamiento (surgical site occurrences requiring procedural intervention, SSOPI) dentro de los 30 días postintervención, los resultados de una encuesta de calidad de vida relacionada con la hernia (HerQles) y la recidiva a largo plazo. Se utilizó un modelo logístico con diferentes covariables clínicas relevantes para generar puntajes de propensión con respecto a la posición de malla. Para analizar el efecto de la posición de la malla, se desarrollaron diferentes modelos de regresión ajustados por las características basales y el puntaje de propensión. RESULTADOS: Se incluyeron en el estudio 4.211 pacientes, 587 con malla intraperitoneal y 3.624 con malla RPS. El análisis con ajuste por puntaje de propensión no mostró diferencias en SSOPI (razón de oportunidades, odds ratio, OR 0,624, i.c. del 95% 0,364-1,07), SSI (OR 0,927, i.c. del 95% 0,475-1,81), puntuación HerQles a 30 días (OR 1,19, i.c. del 95% 0,79-1,8) o en el índice de recidivas (OR 1,28, i.c. del 95% 0,897-1,82). CONCLUSIÓN: La posición de la colocación de la malla no tuvo efecto en los resultados a corto o largo plazo, incluidas las tasas de SSOPI y SSI, las puntuaciones de HerQles y la tasa de recidiva a largo plazo.

Looking beyond the ovary for oncofertility care in women: uterine injury as a potential target for fertility-preserving treatments.

Treatment for cancer has the potential to significantly diminish fertility and, further, to negatively impact the obstetrical outcomes of pregnancies that do occur. Cancer survivors have decreased rates of fertility and increased rates of pregnancy complications, such as preterm birth and low birth weight, after exposure to chemotherapy. To date, research on the impact of chemotherapy and radiotherapy on fertility and pregnancy outcomes has focused largely on the gonadotoxic effect of cancer treatments on ovaries, while the uterus and endometrium have not been extensively studied. It is intuitive, however, that decreased fertility and poorer obstetrical outcomes may be substantially mediated through injury to a highly mitotic tissue like the endometrium, which is also central to embryo implantation and utero-placental exchange. Pregnancy complications in cancer survivors might be due to compromised blood supply to the endometrium and myometrium affecting placentation or altered remodeling of the pregnant uterus secondary to radiation fibrosis. Alterations in endometrial receptivity at the molecular level could affect pregnancy implantation and early pregnancy loss, but later complications also can occur. This review focuses on understanding the unintended effects of chemotherapy and radiotherapy on uterine function in female cancer survivors and the impact on pregnancy, and summarizes mechanisms to protect and treat the uterus before and after cancer chemotherapy and radiotherapy.

Capillary film and breakup mechanism in the squeezing to dripping transition regime at the mesoscale between micro and milli-fluidics.

We report a study of droplet generation in two phase flows of non-miscible fluids in a T-shaped array of circular channels, at the mesoscale between micro- and milli-fluidics. Our experiments show that the balance between the different types of forces (capillary forces, shear viscous forces, etc.) may differ significantly from that found by previous authors in smaller, microfluidics channels. The results may, therefore, be applied to practical systems in which droplets act as small chemical reactors or help enhance mixing. We suggest a possible interesting extension to the generation of drops inside porous media. We report experiments in which the length of the droplets and the residual thickness of the surrounding fluid film are systematically measured as a function of the respective flow rates of the two fluids: These results are carefully compared to theoretical models taking into account in different ways the capillary and viscous effects and to results obtained by other authors for smaller channels. Several dimensionless control variables are tested (capillary number, ratio of the flow rates of the two fluids, etc.). Capillary film thickness is shown to be a useful variable to identify the different regimes of formation. Testing of the theoretical models with the experimental data showed that the change from one formation regime to the other is accompanied by a change in the role of viscous effects. Two models of breakup mechanisms were tested: on the one hand, the pressure buildup mechanism and, on the other hand, a second mechanism corresponds to the balance of tangential shear stresses and interfacial tension. According to the formation regimes, both models have provided satisfactory predictions of the experimental results. However, at this mesoscale, the experimental data were better described by the models dependent on the capillary number, as previously reported in systems with a low degree of confinement.

Shaken baby syndrome and the risk of losing scientific scrutiny.

A systematic review of shaken baby syndrome by the Swedish Agency for Health Technology Assessment and Assessment of Social Services generated numerous reactions from professional organisations, even before the review was published. There was also a lively debate after a paper summarising its findings were published in Acta Paediatrica The various responses are worth debating further, as they raise several important issues with regard to research ethics, having an open debate and publishing scientific findings. CONCLUSION: The responses to the shaken baby syndrome report indicate that scientific scrutiny risks being lost when researchers and organisations are not open to challenging established ideas.

Development of Improved Radiation Drive Environment for High Foot Implosions at the National Ignition Facility.

Analyses of high foot implosions show that performance is limited by the radiation drive environment, i.e., the hohlraum. Reported here are significant improvements in the radiation environment, which result in an enhancement in implosion performance. Using a longer, larger case-to-capsule ratio hohlraum at lower gas fill density improves the symmetry control of a high foot implosion. Moreover, for the first time, these hohlraums produce reduced levels of hot electrons, generated by laser-plasma interactions, which are at levels comparable to near-vacuum hohlraums, and well within specifications. Further, there is a noteworthy increase in laser energy coupling to the hohlraum, and discrepancies with simulated radiation production are markedly reduced. At fixed laser energy, high foot implosions driven with this improved hohlraum have achieved a 1.4×increase in stagnation pressure, with an accompanying relative increase in fusion yield of 50% as compared to a reference experiment with the same laser energy.

The role of in-depth reproductive health counseling in addressing reproductive health concerns in female survivors of nongynecologic cancers.

The purpose of this study was to characterize reproductive concerns among female cancer survivors and determine the role of targeted counseling in improving overall reproductive quality of life (QOL). A survey was administered to women from the California Cancer Registry, ages 18-40, with nongynecologic cancers diagnosed from 1993 to 2007, who received fertility-compromising treatments. In total, 356 women completed the survey, which included questions regarding their reproductive health counseling history and the reproductive concerns scale (RCS), a validated reproductive QOL tool. Factors independently associated with higher RCS scores included a desire for children at the time of diagnosis, posttreatment infertility, treatment with chemoradiation or bone marrow transplant, and income less than $100,000 per year at diagnosis. Among the highest reported reproductive concerns were those related to loss of control over one's reproductive future and concerns about the effect of illness on one's future fertility. Across our population and independent of age, in-depth reproductive health counseling prior to cancer treatment was associated with significantly lower RCS scores. Our findings highlight the importance of early counseling and targeting high-risk groups for additional counseling after completion of cancer treatment. This approach may be an effective strategy for optimizing long-term reproductive QOL in this vulnerable population.

Failure mode and effects analysis of the universal anaesthesia machine in two tertiary care hospitals in Sierra Leone.

BACKGROUND: Anaesthesia care in developed countries involves sophisticated technology and experienced providers. However, advanced machines may be inoperable or fail frequently when placed into the austere medical environment of a developing country. Failure mode and effects analysis (FMEA) is a method for engaging local staff in identifying real or potential breakdowns in processes or work systems and to develop strategies to mitigate risks. METHODS: Nurse anaesthetists from the two tertiary care hospitals in Freetown, Sierra Leone, participated in three sessions moderated by a human factors specialist and an anaesthesiologist. Sessions were audio recorded, and group discussion graphically mapped by the session facilitator for analysis and commentary. These sessions sought to identify potential barriers to implementing an anaesthesia machine designed for austere medical environments-the universal anaesthesia machine (UAM)--and also engaging local nurse anaesthetists in identifying potential solutions to these barriers. RESULTS: Participating Sierra Leonean clinicians identified five main categories of failure modes (resource availability, environmental issues, staff knowledge and attitudes, and workload and staffing issues) and four categories of mitigation strategies (resource management plans, engaging and educating stakeholders, peer support for new machine use, and collectively advocating for needed resources). CONCLUSIONS: We identified factors that may limit the impact of a UAM and devised likely effective strategies for mitigating those risks.

Preoperative optimization in hernia surgery: are we really helping or are we just stalling?

BACKGROUND: Managing patients with abdominal wall hernias and multiple comorbidities can be challenging because these patients are at increased risk for postoperative complications. Preoperative optimization has been used to identify and intervene upon modifiable risk factors to improve hernia repair outcomes, however, waiting to achieve optimization may cause unnecessary delays. METHODS: We describe our approach to preoperative optimization in hernia and we review the current evidence for preoperative optimization. CONCLUSION: Modifying risk factors before undergoing elective hernia repair can improve the overall health of patients with multiple comorbidities. However, when considering the hernia-specific data, prolonging waiting times for patients to achieve full optimization is not justified. Surgeons should take a nuanced approach to balance achieving patient optimization without unnecessarily delaying surgical care.

Abdominal wall mass resections: single-center closure practices and outcomes following oncologic resections of abdominal wall fascia.

PURPOSE: Radical resections for abdominal wall tumors are rare, thus yielding limited data on reconstruction of defects. We describe surgical management and long-term outcomes following radical tumor resection. METHODS: This was a single-center retrospective review of patients between January 2010 and December 2022. Variables included operative characteristics, wound complications, hernia development, tumor recurrence, and reoperation. A multivariable analysis compared wound morbidity for suture and mesh repairs while adjusting for defect width, fascial closure, and CDC wound class. RESULTS: 120 patients were identified. Mean follow-up was 3.9 ± 3.4 years. Seventy-five (62.5%) of the masses were primary; most commonly desmoid (n = 25) and endometrioma (n = 27). Forty-five masses were metastases. Mean tumor width was 6.2 ± 3.4 cm; mean defect width was 8.1 ± 4.1 cm. Sixty-one patients (50.8%) had mesh placed, with variation in technique. Postoperative CT scans were available for 88 (73.3%) patients. Forty SSOs (33.3%), 11 SSIs (9.2%), and 18 (15%) SSOPIs occurred within 30 days. On multivariable analysis, increased defect width was associated with SSOPI (OR 1.17, p = 0.041) and CDC wound class II-III was associated with SSI (OR 8.38 and 49.1, p < 0.05) and SSOPI (OR 5.77 and 17.4, p < 0.05); mesh was not associated with these outcomes. Seven patients (5.8%) underwent 30-day reoperations and 35 (20.8%) required additional operations after 30 days. Thirteen percent developed abdominal wall (n = 8) or intra-abdominal tumor recurrence (n = 8) requiring reoperation. Twenty-seven (22.5%) patients developed hernias with a mean fascial defect width of 9.8 ± 7.2 cm. CONCLUSION: Abdominal wall mass resections are morbid, often contaminated cases with high postoperative complication rates. Risks and benefits of mesh implantation should be tailored on an individual basis.

Determining the value of the abdominal core health quality collaborative to support regulatory decisions.

PURPOSE: The study objective is to document value created by real-world evidence from the Abdominal Core Health Quality Collaborative (ACHQC) for regulatory decisions. The ACHQC is a national effort that generates data on hernia repair techniques and devices. METHODS: Two retrospective cohort evaluations compared cost and time of ACHQC analyses to traditional postmarket studies. The first analysis was based on 25 reports submitted to the European Medicines Agency of 20 mesh products for post-market surveillance. A second analysis supported label expansion submitted to the Food and Drug Administration, Center for Devices and Radiological Health for a robotic-assisted surgery device to include ventral hernia repair. Estimated costs of counterfactual studies, defined as studies that might have been done if the registry had not been available, were derived from a model described in the literature. Return on investment, percentage of cost savings, and time savings were calculated. RESULTS: 45,010 patients contributed to the two analyses. The cost and time differences between individual 25 ACHQC analyses (41,112 patients) and traditional studies ranged from $1.3 to $2.2 million and from 3 to 4.8 years, both favoring use of the ACHQC. In the second label expansion analysis (3,898 patients), the estimated return on investment ranged from 11 to 461% with time savings of 5.1 years favoring use of the ACHQC. CONCLUSIONS: Compared to traditional postmarket studies, use of ACHQC data can result in cost and time savings when used for appropriate regulatory decisions in light of key assumptions.

Can surgeons accurately identify mesh type when interpreting computed tomography scans after ventral hernia repair?

BACKGROUND: Recurrent ventral hernia repair can be challenging due to scarred tissue planes and the increasing complexity of disease related to multiple recurrences. Given the challenges of acquiring complete and accurate prior operative reports, surgeons often rely on computed tomography (CT) scans to obtain information and plan for re-operation. Still, the contribution of CT scans and the ability of surgeons to interpret them is controversial. Previously, we examined the ability of surgeons to determine prior operative techniques based on CT scans. Here, we assessed the accuracy of expert abdominal wall reconstruction (AWR) surgeons in identifying the type of prior mesh using CT imaging. METHODS: A total of 22 highly experienced AWR surgeons were asked to evaluate 21 CT scans of patients who had undergone open ventral hernia repair with bilateral transversus abdominis release utilizing mesh. The surgeons were required to identify the mesh type from a multiple-choice selection. Additionally, negative controls (patients without a history of prior laparotomy) and positive controls (patients with laparotomy but no ventral hernia repair) were incorporated. The accuracy of the surgeons and interrater reliability was calculated. RESULTS: The accuracy rate of the surgeons in correctly identifying the mesh type was 46%, with heavy-weight synthetic mesh (HWSM) being identified only 35.4% of the time, Strattice mesh and medium-weight synthetic mesh (MWSM) were identified at 46.3%, and 51.8%, respectively. The interrater reliability analysis found a moderate level of agreement 0.428 (95% CI 0.356-0.503), and the repeatability measure was poor-0.053 (95% CI 0-0.119); this indicates that surgeons cannot reliably replicate the identification process. CONCLUSIONS: Surgeons' ability to accurately identify the type of previous mesh using CT scans is poor. This study underscores the importance of documenting the type of mesh used in the operative report and the need for standardized operative notes to improve the accuracy and consistency of documentation.

Outcomes of complex abdominal wall reconstruction in patients with connective tissue disorders: a single center experience.

INTRODUCTION: Individuals diagnosed with connective tissue disorders (CTD) are known to be predisposed to incisional hernia formation. However, there is a scarcity of data on outcomes for these patients undergoing hernia repair. We sought to describe our outcomes in performing abdominal wall reconstructions in these complex patients. METHODS: Adult patients with CTD undergoing open, elective, posterior component separation with permanent synthetic mesh at our institution from January 2018 to October 2022 were queried from a prospectively collected database in the Abdominal Core Health Quality Collaborative. We evaluated 30-day wound morbidity, perioperative complications, long-term hernia recurrence, and patient-reported quality of life. RESULTS: Twelve patients were identified. Connective tissue disorders included Marfan's n = 7 (58.3%), Loeys-Dietz syndrome n = 2 (16.7%), Systemic Lupus Erythematosus n = 2 (16.7%), and Scleroderma n = 1 (8.3%). Prior incisions included three midline laparotomies and nine thoracoabdominal, mean hernia width measured 14 cm, and 9 were recurrent hernias. Surgical site occurrences (SSOs) were observed in 25% of cases, and 16.7% necessitated procedural intervention. All twelve patients were available for long-term follow-up, with a mean of 34 (12-62) months. There were no instances of reoperation or mesh excision related to the TAR procedure. One patient developed a recurrence after having his mesh violated for repair of a new visceral aneurysm. Mean HerQLes scores at 1 year were 70 and 89 at ≥ 2 years; Mean scaled PROMIS scores were 30.7 at 1 year and 36.3 at ≥ 2 years. CONCLUSION: Ventral hernia repair with TAR is feasible in patients with connective tissue disorder and can be a suitable alternative in patients with large complex hernias.

Outcomes of posterior sheath supplementation with Vicryl mesh in TAR-a single-center study.

INTRODUCTION: In the Transversus Abdominis Release (TAR) procedure, ideally, the posterior sheath is completely reapproximated to establish an interface isolating the polypropylene mesh from visceral contents. When primary closure of the posterior sheath is unachievable, Vicryl mesh is commonly used to supplement the posterior sheath closure and an uncoated polypropylene mesh is placed superficial to the Vicryl mesh. The long-term implications of utilizing Vicryl mesh as an antiadhesive barrier are poorly understood. In this study, we aimed to assess our outcomes when utilizing Vicryl mesh to supplement the posterior sheath defects when placed underneath polypropylene mesh in patients undergoing posterior component separation. METHODS: Adult patients who underwent VHR with concurrent TAR procedure with a permanent synthetic mesh and posterior sheath supplementation with Vicryl mesh in the Cleveland Clinic Center for Abdominal Core Health between January 2014 and December 2022 were queried retrospectively from a prospectively collected database in the Abdominal Core Health Quality Collaborative. We evaluated 30-day wound morbidity, perioperative complications, long-term mesh-related complications, and pragmatic hernia recurrence. RESULTS: 53 patients who underwent TAR procedure with posterior sheath supplementation using Vicryl mesh and had a minimum 12-month follow-up were identified. Of the 53 patients, 94.3% presented with recurrent hernias, 73.6% had a midline hernia, 7.5% had a flank hernia, and 18.9% had concurrent parastomal hernia. The mean hernia width was 24.9 cm (± 8.8 cm). No Vicryl mesh-related operative complications were identified in our study, with no instances of mesh erosion, fistulas, or interventions for small bowel obstruction. Skin necrosis requiring reoperations was observed in three patients (5.7%), leading to permanent mesh excision in two cases (3.8%) without intraabdominal visceral involvement. Throughout the 12-month follow-up, 23 incidences (43.4%) of surgical site occurrences (SSOs) and surgical site occurrences requiring procedural intervention (SSOPI) were documented. CONCLUSIONS: Our findings suggest that posterior sheath supplementation with Vicryl mesh is a feasible approach to achieve posterior sheath closure in challenging abdominal wall reconstruction cases. Given the absence of notable mesh-related complications and a similar hernia recurrence rate to cases without posterior sheath supplementation, Vicryl mesh can be used to safely achieve posterior sheath closure in complex reconstructions with insufficient native tissue.

Cannabis smoking and abdominal wall reconstruction outcomes: a propensity score-matched analysis.

PURPOSE: Despite increasing use of cannabis, literature on perioperative effects is lagging. We compared active cannabis-smokers versus non-smokers and postoperative wound morbidity and reoperations following open abdominal wall reconstruction (AWR). METHODS: Patients who underwent open, clean, AWR with transversus abdominis release and retromuscular synthetic mesh placement at our institution between January 2014 and May 2022 were identified using the Abdominal Core Health Quality Collaborative database. Active cannabis-smokers were 1:3 propensity matched to non-smokers based on demographics and comorbidities. Wound complications, 30 day morbidity, pain (PROMIS 3a-Pain Intensity), and hernia-specific quality of life (HerQles) were compared. RESULTS: Seventy-two cannabis-smokers were matched to 216 non-smokers. SSO (18% vs 17% p = 0.86), SSI (11.1% vs 9.3%, p = 0.65), SSOPI (12% vs 12%, p = 0.92), and all postoperative complications (46% vs 43%, p = 0.63) were similar between cannabis-smokers and non-smokers. Reoperations were more common in the cannabis-smoker group (8.3% vs 2.8%, p = 0.041), driven by major wound complications (6.9% vs 3.2%, p = 0.004). No mesh excisions occurred. HerQles scores were similar at baseline (22 [11, 41] vs 35 [14, 55], p = 0.06), and were worse for cannabis-smokers compared to non-smokers at 30 days (30 [12, 50] vs 38 [20, 67], p = 0.032), but not significantly different at 1 year postoperatively (72 [53, 90] vs 78 [57, 92], p = 0.39). Pain scores were worse for cannabis-smokers compared to non-smokers at 30 days postoperatively (52 [46, 58] vs 49 [44, 54], p = 0.01), but there were no differences at 6 months or 1 year postoperatively (p > 0.05 for all). CONCLUSION: Cannabis smokers will likely experience similar complication rates after clean, open AWR, but should be counseled that despite similar wound complication rates, the severity of their wound complications may be greater than non-smokers.

Outcomes of posterior component separation with transversus abdominis release for repair of abdominally based breast reconstruction donor site hernias.

PURPOSE: Abdominally based autologous breast reconstruction (ABABR) is common after mastectomy, but carries a risk of complex abdominal wall hernias. We report experience with posterior component separation (PCS) and transversus abdominis release (TAR) with permanent synthetic mesh repair of ABABR-related hernias. METHODS: Patients at Cleveland Clinic Foundation and Penn State Health were identified retrospectively. Outcomes included postoperative complications, hernia recurrence, and patient-reported outcomes (PROs): Hernia Recurrence Inventory, HerQLes Summary Score, Patient-Reported Outcome Measurement Information System (PROMIS) Pain Intensity 3a Survey, and the Decision Regret Scale (DRS). RESULTS: Forty patients underwent PCS/TAR repair of hernias resulting from pedicled (35%), free (5%), muscle-sparing TRAMs (15%), and DIEPs (28%) from August 2014 to March 2021. Following PCS, 30-day complications included superficial surgical site infection (13%), seroma (8%), and superficial wound breakdown (5%). Five patients (20%) developed clinical hernia recurrence. At a minimum of 1 year, 17 (63%) reported a bulge, 12 (44%) reported pain, median HerQLes Quality Of Life Scores improved from 33 to 63/100 (p value < 0.01), PROMIS 3a Pain Intensity Scores improved from 52 to 38 (p value < 0.05), and DRS scores were consistent with low regret (20/100). CONCLUSION: ABABR-related hernias are complex and technically challenging due to missing abdominal wall components and denervation injury. After repair with PCS/TAR, patients had high rates of recurrence and bulge, but reported improved quality of life and pain and low regret. Surgeons should set realistic expectations regarding postoperative bulge and risk of hernia recurrence.
