RESUMO
BACKGROUND: Women undergoing immediate breast reconstruction without radiation therapy have reconstruction methods available with uncertain long-term costs associated with complications requiring surgery and revisions. We evaluated cost-effectiveness of nine methods of immediate breast reconstruction for women with localized breast cancer. METHODS: Markov modeling was performed over 10-years for unilateral/bilateral breast reconstructions from healthcare/societal perspectives. PubMed, Embase, Cochrane, Scopus, and CINAHL were searched to derive data from 13,744 patients in 79 prospective studies. Complications requiring surgery (mastectomy necrosis, total/partial flap necrosis, seroma, hematoma, infection, wound dehiscence, abdominal hernia, implant removal/explantation) and revisions (fat necrosis, capsular contracture, asymmetry, scars/redundant tissue, implant rupture/removal, fat grafting) were evaluated over yearly cycles. Reconstructions included: direct-to-implant (DTI), tissue expander-to-implant (TEI), latissimus dorsi flap-to-implant (LDI), latissimus dorsi (LD), pedicled transverse rectus abdominis myocutaneous (TRAM), free TRAM, deep inferior epigastric perforator/superficial inferior epigastric artery (DIEP/SIEA), thigh-based, or gluteal based flaps. Outcomes were incremental cost-effectiveness ratios (ICER) and net monetary benefits (NMB). Willingness-to-pay thresholds were $50,000 and $100,000. RESULTS: From a healthcare perspective for unilateral reconstruction, compared to LD, the ICER for DTI was -$42,109.35/quality-adjusted life-years (QALY), LDI was -$25,300.83/QALY, TEI was -$22,036.02/QALY, DIEP/SIEA was $8307.65/QALY, free TRAM was $8677.26/QALY, pedicled TRAM was $13,021.44/QALY, gluteal-based was $17,698.99/QALY, and thigh-based was $23,447.82/QALY. NMB of DIEP/SIEA was $404,523.47, free TRAM was $403,821.40, gluteal-based was $392,478.64, thigh-based was $387,691.70, pedicled TRAM was $376,901.83, LD was $370,646.93, DTI was $339,668.77, LDI was $334,350.30, and TEI was $329,265.84. CONCLUSIONS: All nine methods of immediate breast reconstruction were considered cost-effective from healthcare/societal perspectives. LD provided the lowest costs, while DIEP/SIEA provided the greatest effectiveness and NMB.

INTRODUCTION: Soft-tissue reconstruction of the scalp has traditionally been challenging in oncologic patients. Invasive tumors can compromise the calvarium, necessitating alloplastic cranioplasty. Titanium mesh is the most common alloplastic material, but concerns of compromise of soft-tissue coverage have introduced hesitancy in utilization. The authors aim to identify prognostic factors associated with free-flap failure in the context of underlying titanium mesh in scalp oncology patients. METHODS: A retrospective review (2010-2018) was conducted at a single center examining all patients following oncologic scalp resection who underwent titanium mesh cranioplasty with free-flap reconstruction following surgical excision. Patient demographics, comorbidities, ancillary oncological treatment information were collected. Operative data including flap type, post-operative complications including partial and complete flap failure were collected. RESULTS: A total of 16 patients with 18 concomitant mesh cranioplasty and free-flap reconstructions were identified. The majority of patients were male (68.8%), with an average age of 70.5 years. Free-flap reconstruction included 15 ALT flaps (83.3%), 2 latissimus flaps (11.1%), and one radial forearm flap (5.5%). There were three total flap losses in two patients. Patient demographics and comorbidities were not significant prognostic factors. Additionally, post-operative radiation therapy, ancillary chemotherapy, oncological histology, tumor recurrence, and flap type were not found to be significant. Pre-operative radiotherapy was significantly associated with flap failure (P < 0.05). CONCLUSION: Pre-operative radiotherapy may pose a significant risk for free-flap failure in oncologic patients undergoing scalp reconstruction following mesh cranioplasty. Awareness of associated risk factors ensures better pre-operative counseling and success of these reconstructive modalities and timing of pre-adjuvant treatment.

Background Despite guideline-compliant prophylaxis, an increased rate of deep venous thrombosis (DVT) formation has been reported following autologous versus implant-based breast reconstruction. We hypothesized that tight abdominal fascia closure might decrease lower extremity venous return and promote venous stasis. Methods An observational crossover study of patients who underwent autologous breast reconstruction using transverse rectus abdominis musculocutaneous/deep inferior epigastric artery perforator flaps was conducted. Ultrasonographic measurements of the left common femoral vein (CFV) and right internal jugular vein (IJV) were performed preoperatively, in the postanesthesia care unit, and on postoperative day (POD) 1. Parameters of interest included vessel diameter, circumference, area, and maximum flow velocity. Results Eighteen patients with a mean age and body mass index of 52.7 years (range, 29-76 years) and 31.3 kg/m2 (range, 21.9-43.4 kg/m2) were included, respectively. A 29.8% increase in CFV diameter was observed on POD 1 (p < 0.0001). Similarly, a 24.3 and 69.9% increase in CFV circumference (p = 0.0007) and area (p < 0.0001) were noted, respectively. These correlated with a 28.4% decrease in maximum flow velocity in the CFV (p = 0.0001). Of note, none of these parameters displayed significant changes for the IJV, thus indicating that observed changes in the CFV were not the result of changes in perioperative fluid status. Conclusion Postoperative changes observed in the CFV reflect increased lower extremity venous stasis after microsurgical breast reconstruction and may contribute to postoperative DVT formation.

BACKGROUND: Adipose-derived stem cells (ASCs) are a powerful tool for cosmetic surgery and regenerative medicine. The use of autologous platelet rich plasma (PRP), particularly in combination with ASC-based therapy, has significantly expanded in recent years. Unfortunately, the mechanisms and optimal dosing responsible for the beneficial effects of PRP remain poorly understood. Here we investigate the effect of PRP on ASC growth and differentiation. OBJECTIVES: To assess the impact of different PRP feeding and cryopreservation protocols on ASC isolation, expansion, and differentiation. METHODS: Human PRP was isolated using the Magellan System (Arteriocyte). Fresh PRP (fPRP), flash frozen PRP (ffPRP), and cryopreserved PRP (cPRP) were added to human ASCs isolated from healthy patients. A panel of PRP supplementation protocols was analyzed for ASC adherence, proliferation, and osteogenesis. RESULTS: The fresh and cryopreserved PRP groups demonstrated reduced cell adherence compared to control (non-PRP) groups (P < 0.001), while the flash frozen PRP groups showed cell adherence equivalent to or better than controls. After 7 days of growth, ASC populations for fPRP and ffPRP Single Administration protocols were significantly higher than other feeding protocols and controls. This benefit was lost in cPRP groups. Optimized ffPRP protocols showed potential for spontaneous osteogenesis. CONCLUSIONS: Addition of ffPRP improves initial ASC adherence while a single administration of either fresh or flash frozen PRP without additional cell manipulation significantly augments subsequent ASC proliferation. The potential for spontaneous osteogenic differentiation upon PRP exposure invokes the need for additional molecular studies of PRP activity prior to further expansion to clinical applications.

Background: The use of deep inferior epigastric perforator (DIEP) flaps is a well-established breast reconstruction technique. Methods: A 29-question survey was e-mailed to 3186 active American Society of Plastic Surgeons members, aiming to describe postoperative monitoring practice patterns among surgeons performing DIEP flaps. Results: From 255 responses (8%), 79% performing DIEP surgery were analyzed. Among them, 34.8% practiced for more than 20 years, 34.3% for 10-20 years, and 30.9% for less than 10 years. Initial 24-hour post-DIEP monitoring: intensive care unit (39%) and floor (36%). Flap monitoring: external Doppler (71%), tissue oximetry (41%), and implantable Doppler (32%). Postoperative analgesia: acetaminophen (74%), non-steroidal anti-inflammatory drugs (69%), neuromodulators (52%), and opioids (4.4%) were administered on a scheduled basis. On postoperative day 1, 61% halt intravenous fluids, 67% allow ambulation, 70% remove Foley catheter, and 71% start diet. Most surgeons discharged patients from the hospital on postoperative day 3+. Regardless of experience, patients were commonly discharged on day 3. Half of the surgeons are in academic/nonacademic settings and discharge on/after day 3. Conclusions: This study reveals significant heterogeneity among the practice patterns of DIEP surgeons. In light of these findings, it is recommended that a task force be convened to establish standardized monitoring protocols for DIEP flaps. Such protocols have the potential to reduce both the length of hospital stays and overall care costs all while ensuring optimal pain management and vigilant flap monitoring.
RESUMO
BACKGROUND: Oncologic resection of the scalp confers several obstacles to the reconstructive surgeon dependent upon patient-specific and wound-specific factors. We aim to describe our experiences with various reconstructive methods, and delineate risk factors for coverage failure and complications in the setting of scalp reconstruction. METHODS: A retrospective chart review was conducted, examining patients who underwent resection of fungating scalp tumors with subsequent soft-tissue reconstruction from 2003 to 2019. Patient demographics, wound and oncologic characteristics, treatment modalities, and outcomes were recorded and analyzed. RESULTS: A total of 189 patients were appropriate for inclusion, undergoing a range of reconstructive methods from skin grafting to free flaps. Thirty-three patients (17.5%) underwent preoperative radiation. In all, 48 patients (25.4%) suffered wound site complications, 25 (13.2%) underwent reoperation, and 47 (24.9%) suffered from mortality. Preoperative radiation therapy was an independent risk factor for wound complications (odds ratio [OR], 2.85; 95% confidence interval [CI], 1.1-7.3; p = 0.028) and reoperations (OR, 4.45; 95% CI, 1.5-13.2; p = 0.007). Similarly, the presence of an underlying titanium mesh was an independent predictor of wound complications (OR, 2.49; 95% CI, 1.1-5.6; p= 0.029) and reoperations (OR, 3.40; 95% CI, 1.2-9.7; p= 0.020). Both immunosuppressed status (OR, 2.88; 95% CI, 1.2-7.1; p= 0.021) and preoperative radiation therapy (OR, 3.34; 95% CI, 1.2-9.7; p= 0.022) were risk factors for mortality. CONCLUSION: Both preoperative radiation and the presence of underlying titanium mesh are independent risk factors for wound site complications and increased reoperation rates following oncologic resection and reconstruction of the scalp. Additionally, preoperative radiation, along with an immunosuppressed state, may predict patient mortality following scalp resection and reconstruction.
RESUMO
BACKGROUND: Retromuscular hernia repairs (RHRs) decrease hernia recurrence and surgical site infections but can cause significant pain. We aimed to determine if pain and postoperative outcomes differed when comparing suture fixation (SF) of mesh to fibrin glue fixation (FGF). METHODS: Patients undergoing RHR (n = 87) between December 1, 2015 and December 31, 2017 were retrospectively identified. Patients received SF of mesh (n = 59, 67.8%) before the senior author changing his technique to FGF (n = 28, 32.2%). These 2 cohorts were matched (age, body mass index, number of prior repairs, mesh type, defect size, and wound class). Outcomes were analyzed using a matched pairs design with multivariable linear regression. RESULTS: Two matched groups (21 FGF and 21 SF) were analyzed (45.2% female, average age 56 years, average body mass index 34.7 kg/m2, and average defect size 330 cm2). Statistical significance was observed for FGF compared with SF: length of stay (3.7 versus 7.1 days, P = 0.032), time with a drain (17.2 versus 27.5 days, P = 0.012), 30-day postoperative visits (2 versus 3, P = 0.003), pain scores (5.2 versus 3.1, P = 0.019) and activity within the first 24 hours (walking versus sitting, P = 0.002). Operative time decreased by 23.1 minutes (P = 0.352) and postoperative narcotic represcription (3 versus. 8 patients, p=0.147) also decreased. Average cost for patients receiving SF was $36,152 compared to $21,782 for FGF (P = 0.035). CONCLUSIONS: Sutureless RHR using FGF may result in decreased pain when compared with a matched cohort receiving SF, translating to enhanced recovery time, shortened hospital stay, and decreased costs.
RESUMO
BACKGROUND: Index finger (IF) pollicization is the standard treatment for severe congenital thumb hypoplasia. The procedure requires a supple and anatomically normal IF. No guidelines exist for IF pollicization in patients who have concomitantly underdeveloped IF, specifically when the digit has only 2 phalanges and 1 interphalangeal joint. METHODS: We present a case of a 20-month-old boy with congenital type IV thumb hypoplasia who also had biphalangeal IF. We proposed an IF pollicization operation that required significant modifications to the traditional procedure. RESULTS: Preoperative planning and intraoperative execution are described. The modifications to the traditional procedure included: (1) removal of proximal third of IF metacarpal; (2) creation of a de novo thumb carpometacarpal (CMC) joint by fibrous union whereby the IF CMC joint cartilaginous components are maintained and the remaining distal IF metacarpal is translocated down and secured to this cartilage (in contrast to the traditional use of IF metacarpophalangeal joint as a de novo thumb CMC joint); (3) preservation of IF joints at their "natural" position and function; (4) maintenance of intrinsic muscles at their original distal insertion sites; and (5) important adjustments to skin incision. CONCLUSIONS: Pollicization of biphalangeal IF can be executed in a safe and efficient manner. Early recovery has shown promising signs. Long-term results, including the de novo thumb CMC joint function, remain to be evaluated.

Prophylactic mesh augmentation (PMA) is the implantation of mesh during closure of an index laparotomy to decrease a patient's risk for developing incisional hernia (IH). The current body of evidence lacks refined guidelines for patient selection, mesh placement, and material choice. The purpose of this study is to summarize the literature and identify areas of research needed to foster responsible and appropriate use of PMA as an emerging technique. We conducted a comprehensive review of Scopus, Cochrane, PubMed, and

Incisional hernia (IH) is a challenging, potentially morbid condition. This study evaluates recent trends in hospital encounters associated with IH care in the United States. Using Nationwide Inpatient Sample databases from 2007 to 2011, annual estimates of IH-related hospital discharges, charges, and serious adverse events were identified. Significance in observed trends was tested using regression modeling. From 2007 to 2011, there were 583,054 hospital discharges associated with a diagnosis of IH. 81.1 per cent had a concurrent procedure for IH repair. The average discharge included a female patient (63.2%), 59.8 years of age, with either Medicare (45.3%) or Private insurance (38.3%) as the anticipated primary payer. Comparing 2007 to 2011, significant increases in IH discharges (12%; 2007 = 109,702 vs 2011 = 123,034, P = 0.009) and IH repairs (10%; 2007 = 90,588 vs 2011 = 99,622, P < 0.001) were observed. This was accompanied by a 37 per cent increase in hospital charges (2007 = $44,587 vs 2011 = $60,968, P < 0.001), resulting in a total healthcare bill of $7.3 billion in 2011. Significant trends toward greater patient age (2007 = 59.7 years vs 2011 = 60.2 years, P < 0.001), higher comorbidity index (2007 = 3.0 vs 2011 = 3.5, P < 0.001), and increased frequency of serious adverse events (2007 = 13.5% vs 2011 = 17.7%, P < 0.001) were noted. Further work is needed to identify interventions to mitigate the risk of IH development.

BACKGROUND: The establishment of an effective clinical and academic culture within an institution is a multifactorial process. This process is cultivated by dynamic elements such as recruitment of an accomplished and diverse faculty, patient geographic outreach, clinical outcomes research, and fundamental support from all levels of an institution. This study reviews the academic evolution of a single academic plastic surgery practice, and summarizes a 10-year experience of microsurgical development, clinical outcomes, and academic productivity. METHODS: A 10-year retrospective institutional review was performed from fiscal years 2006 to 2016. Microsurgical flap type and operative volume were measured across all microsurgery faculty and participating hospitals. Microvascular compromise and flap salvage rates were noted for the six highest volume surgeons. Univariate and multivariable predictors of flap salvage were determined. RESULTS: The 5000th flap was performed in December of 2015 within this institutional study period. Looking at the six highest volume surgeons, free flaps were examined for microvascular compromise, with an institutional mean take-back rate of 1.53 percent and flap loss rate of 0.55 percent across all participating hospitals. Overall, 74.4 percent of cases were breast flaps, and the remaining cases were extremity and head and neck flaps. CONCLUSIONS: Focused faculty and trainee recruitment has resulted in an academically and clinically productive practice. Collaboration among faculty, staff, and residents contributes to continual learning, innovation, and quality patient care. This established framework, constructed based on experience, offers a workable and reproducible model for other academic plastic surgery institutions. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

INTRODUCTION: Incisional hernia (IH) represents a complex and costly surgical complication. We aim to address trends in open surgery to better understand potential drivers of hernia risk. MATERIAL AND METHODS: Using the 2009-2013 NIS, a cross-sectional review of hospital discharges associated with an open abdominal surgery was performed. RESULTS: Between 2009 and 2013, there were nearly 10 million discharges associated with an open abdominal surgery. Overall, there were 2,140,616 patients receiving open surgery in 2009, decreasing to 1,760,549 in 2013 (18% decrease, p < 0.001). Open hernia procedures increased from 37,325 patients in 2009 to 41,845 in 2013 (12% increase, p = 0.001). The most prevalent comorbidities within this population included uncomplicated hypertension (25.26%), chronic pulmonary diseases (13.52%), obesity (10.24%), uncomplicated diabetes (11.06%), and depression (10.72%). CONCLUSIONS: Our analysis allowed for a unique view of surgical trends, health care population dynamics, and an opportunity to use evidence-driven analytics in the understanding of IH.

Importance: Health care professionals do not adequately stratify risk or provide prophylaxis for venous thromboembolism (VTE) among surgical patients. Computerized clinical decision support systems (CCDSSs) have been implemented to assist clinicians and improve prophylaxis for VTE. Objective: To evaluate the effect of implementing CCDSSs on the ordering of VTE prophylaxis and the rates of VTE. Data Sources: PubMed, MEDLINE via OVID, EMBASE via OVID, Scopus, Cochrane CENTRAL Register of Controlled Trials, and clinicaltrials.gov were searched in June 2016 for articles published in English from October 15, 1991, to February 16, 2016. A manual search of references from relevant articles was also performed. Study Selection: Clinical trials and observational studies among surgical patients comparing CCDSSs with VTE risk stratification and assistance in ordering prophylaxis vs routine care without decision support were included. Of the 188 articles screened, 11 (5.9%) were eligible for meta-analysis. Data Extraction and Synthesis: Meta-analysis of Observational Studies in Epidemiology guidelines were followed. Two reviewers extracted data and assessed quality independently. Main Outcomes and Measures: Rates of prophylaxis for VTE and VTE events. Random- and fixed-effects models were used to summarize odds ratios and risk ratios. Results: Eleven articles (9 prospective cohort trials and 2 retrospective cohort trials) comprising 156â¯366 individuals (104â¯241 in the intervention group and 52â¯125 in the control group) were included. The use of CCDSSs was associated with a significant increase in the rate of appropriate ordering of prophylaxis for VTE (odds ratio, 2.35; 95% CI, 1.78-3.10; P < .001) and a significant decrease in the risk of VTE events (risk ratio, 0.78; 95% CI, 0.72-0.85; P < .001). Conclusions and Relevance: Use of CCDSSs increases the proportion of surgical patients who were prescribed adequate prophylaxis for VTE and correlates with a reduction in VTE events.

BACKGROUND: Ventral hernia represents a surgical challenge plagued by high morbidity and recurrence rates. Primary closure of challenging hernias is often prohibited by severe lateral retraction and tension of the abdominal wall musculature. Botulinum toxin injections have recently been identified as a potential pre-operative means to counteract abdominal wall tension, reduce hernia size, and facilitate fascial closure during hernia repair. This systematic review and meta-analysis reviews outcomes associated with botulinum toxin injections in the setting of ventral hernia, and demonstrates an opportunity to leverage this mainstream aesthetic product for use in abdominal wall reconstruction. METHODS: A literature review was conducted according to PRISMA guidelines using MeSH terms 'ventral hernia', 'herniorrhaphy', 'hernia repair', and 'botulinum toxins'. Relevant studies reporting pre- and postinjection data were included. Outcomes of interest included changes in hernia defect width and lateral abdominal muscle length, recurrence, complications, and patient follow-up. Qualitative findings were also considered to help demonstrate valuable themes across the literature. RESULTS: Of 133 results, 12 were included for qualitative review and three for quantitative analysis. Meta-analysis revealed significant hernia width reduction (mean = 5.79 cm; n = 29; p < 0.001) and lateral abdominal wall muscular lengthening (mean = 3.33 cm; n = 44; p < 0.001) following botulinum injections. Mean length of follow-up was 24.7 months (range = 9-49). CONCLUSIONS: Botulinum toxin injections offer tremendous potential in ventral hernia management by reducing hernia width and lengthening abdominal wall muscles prior to repair. Although further studies are needed, there is a significant opportunity to bridge the knowledge gap in preoperative practice measures for ventral hernia risk reduction.

BACKGROUND: Panniculectomy (PAN) is often performed concurrently with ventral hernia repair (VHR) in the obese patient. However, the effectiveness and safety profile of this common practice are not fully established in part because of paucity of comparative effectiveness studies. In this study, a comparative analysis of early complications, long-term hernia recurrence, and healthcare expenditures between VHR-PAN and VHR-only patients is presented. METHODS: From the Healthcare Cost and Utilization Project database, obese patients who underwent VHR with and without concurrent PAN were identified. Multivariate cox proportional-hazards regression modeling was performed to compare outcomes between the two groups. RESULTS: The final cohort included 1013 VHR-PAN and 18,328 VHR-only patients. The VHR-PAN patients experienced a longer adjusted length of hospital stay (6.8 days vs. 5.2 days; p < 0.001), a higher rate of in-hospital adverse events (29.3% vs. 20.7%; AOR = 2.34 [2.01-2.74]), and a higher rate of 30-day readmissions (13.6% vs. 8.1%; AOR = 2.04 [1.69-2.48]). However, the 2-year rate of hernia recurrence was lower in the VHR-PAN group (7.9% vs. 11.3%; AOR = 0.65 [0.51-0.82]). Both groups generated considerable hospital charges ($104,805 VHR-PAN vs. $72,206 VHR-only, p < 0.001). CONCLUSION: Performing a concurrent PAN in the obese hernia patient is associated with a higher rate of early complications and greater healthcare expenditures, but overall a substantially lower incidence of 2-year hernia recurrence. The literature review presented here also highlights a substantial need for further comparative effectiveness studies to create the needed framework for evidence-based guidelines.

BACKGROUND: Incisional hernia remains a persistent and burdensome complication after colectomy. Through individualized risk-assessment and prediction models, we aimed to improve preoperative risk counseling for patients undergoing colectomy; identify modifiable preoperative risk factors; and encourage the use of evidence-based risk-prediction instruments in the clinical setting. STUDY DESIGN: A retrospective review of the Healthcare Cost and Utilization Project data was conducted for all patients undergoing either open or laparoscopic colectomy as identified through the state inpatient databases of California, Florida, and New York in 2009. Incidence of incisional hernia repair was collected from both the state inpatient databases and the state ambulatory surgery and services databases in the 3 states between index surgery and 2011. Hernia risk was calculated with multivariable hierarchical logistic regression modeling and validated using bootstrapping techniques. Exclusion criteria included concurrent hernia, metastasis, mortality, and age younger than 18 years. Inflation-adjusted expenditure estimates were calculated. RESULTS: Overall, 30,741 patients underwent colectomy, one-third of these procedures performed laparoscopically. Incisional hernia repair was performed in 2,563 patients (8.3%) (27-month follow-up). Fourteen significant risk factors were identified, including open surgery (odds ratio = 1.49; p < 0.0001), obesity (odds ratio = 1.49; p < 0.0001), and alcohol abuse (odds ratio = 1.39; p = 0.010). Extreme-risk patients experienced the highest incidence of incisional hernia (19.8%) vs low-risk patients (3.9%) (C-statistic = 0.67). CONCLUSIONS: We present a clinically actionable model of incisional hernia using all-payer claims after colectomy. The data presented can structure preoperative risk counseling, identify modifiable patient-specific risk factors, and advance the field of risk prediction using claims data.

BACKGROUND: Operative intervention to correct incisional hernia affects 150,000 patients annually, with 1 in 3 repairs recurring within 9 years. The aim of this study was to compare the incidence of incisional hernia and postoperative complications in elective midline laparotomy patients after the use of prophylactic mesh placement and primary suture closure. METHODS: A systematic review was performed to identify studies comparing prophylactic mesh placement to primary suture closure in elective, midline laparotomy at index abdominal aponeurosis closure. The primary outcome was incisional hernia. Secondary outcomes included postoperative complications. RESULTS: Fourteen studies were included (2,114 patients), with 1,152 receiving prophylactic mesh placement. Prophylactic mesh placement decreased the risk of incisional hernia overall when compared to primary suture closure (relative risk = 0.15; P < .00001) and in trials using only polypropylene mesh versus 4:1 primary suture closure (relative risk = 0.15; P = .003). Prophylactic mesh placement reduced the risk of incisional hernia regardless of mesh location or composition: onlay (relative risk = 0.07; P < .0001), retrorectus (relative risk = 0.04; P = .002), and preperitoneal (relative risk = 0.18; P = .02). Prophylactic mesh placement increased risk of seroma overall (relative risk = 1.95; P < .0001), onlay (relative risk = 2.43; P = .01) and preperitoneal (relative risk = 1.47; P = .01) but not retrorectus plane (relative risk = 1.55; P = .26). Polypropylene mesh increased seroma risk only in the onlay position (relative risk = 2.77; P = .04). Prophylactic mesh placement patients are at increased risk for chronic wound pain compared to primary suture closure (relative risk = 1.70; P = .03). CONCLUSION: Prophylactic mesh placement is associated with an 85% postoperative incisional hernia risk reduction when compared to primary suture closure in at-risk patients undergoing elective, midline laparotomy closure. This technique appears to be safe with comparable complication profiles, barring an increased risk of seroma, especially with the onlay technique, and the possibility for an increased risk of chronic pain. Despite this verification, evidence from large domestic trials that sufficiently addresses major knowledge gaps is simply lacking.

BACKGROUND: Incisional hernia (IH) is a complication following open abdominal hysterectomy. This study addresses the incidence and health care cost of IH repair after open hysterectomy, and identify perioperative risk factors to create predictive risk models. METHODS: We conduct a retrospective review of patients who underwent open hysterectomy between 2005 and 2013 at the University of Pennsylvania. The primary outcome was post-hysterectomy IH. Univariate/multivariate cox proportional hazard analyses identified perioperative risk factors. We performed cox hazard regression modeling with bootstrapped validation, risk stratification, and assessment of model performance. RESULTS: 2145 patients underwent open hysterectomy during the study period. 76 patients developed IH, and all underwent repair. 31.3% underwent reoperation, generating higher costs ($71,559 vs. $23,313, p < 0.001). 8 risk factors were included in the model, the strongest being presence of a vertical incision (HR = 3.73 [2.01-6.92]). Extreme-risk patients experienced the highest incidence of IH (22%) vs. low-risk patients (0.8%) [C-statistic = 0.82]. CONCLUSIONS: We identify perioperative risk factors for IH and provide a risk prediction instrument to accurately stratify patients in effort to offer risk reductive techniques. SUMMARY: Open hysterectomies account for a magnitude of surgical procedures worldwide. This study presents an internally validated risk model of IH in patients undergoing open hysterectomy after a review of 2145 cases. With an increasing emphasis on prevention in healthcare, we create a risk model to improve outcomes after open hysterectomies in effort to identify high-risk patients, facilitate preoperative risk counseling, and implement evidence-based strategies to improve outcomes.
