RESUMEN
INTRODUCTION: Abdominal wall reconstruction (AWR) in a contaminated field is associated with an increased risk of wound complications, infection, and reoperation. The best method of repair and mesh choice in these operations have generated marked controversy. Our aim was to compare outcomes of patients who underwent AWR with biologic versus synthetic mesh in CDC class 3 and 4 wounds. METHODS: A prospective, single-institution database was queried for AWR using biologic or synthetic mesh in CDC Class 3 and 4 wounds. Hernia recurrence and complications were measured. Multivariable logistic regression was performed to identify factors predicting both. RESULTS: In total, 386 patients with contaminated wounds underwent AWR, 335 with biologic and 51 with synthetic mesh. Groups were similar in age, sex, BMI, and rate of diabetes. Biologic mesh patients had larger hernia defects (298 ± 233cm2 vs. 208 ± 155cm2; p = 0.004) and a higher rate of recurrent hernias (72.2% vs 47.1%; p < 0.001), comorbidities(5.8 ± 2.7 vs. 4.2 ± 2.4, p < 0.01), and a nearly fivefold increase in Class 4 wounds (47.8% vs. 9.8%, p < 0.001), while fascial closure trended to being less common (90.7% vs 96.1%; p = 0.078). Hernia recurrence was comparable between biologic and synthetic mesh (10.4% vs. 17.6%, p = 0.132). Wound complication rates were similar (36.1% vs. 33.3%, p = 0.699), but synthetic mesh had higher rates of mesh infection (1.2% vs 11.8%; p < 0.001) and infection-related resection (0% vs 7.8%, p < 0.001), with 66% of those synthetic mesh infections requiring excision. On logistic regression, wound complications (OR 5.96 [CI 1.60-22.17]; p = 0.008) and bridging mesh (OR 13.10 [CI 2.71-63.42];p = 0.030) predicted of hernia recurrence (p < 0.05), while synthetic mesh (OR 18.6 [CI 2.35-260.4] p = 0.012) and wound complications (OR 20.6 [CI 3.15-417.7] p = 0.008) predicted mesh infection. CONCLUSIONS: Wound complications in AWR with CDC class 3 and 4 wounds significantly increased mesh infection and hernia recurrence; failure to achieve fascial closure also increased hernia recurrence. Use of synthetic versus biologic mesh increased the mesh infection rate by 18.6 times.

BACKGROUND: Barrier-coated meshes were designed to reduce adhesion formation between mesh and the surrounding viscera. There have been questions raised but little data to determine if rapidly absorbable coatings pose an increased risk of infection. The objective of this study was to determine if a difference exists in wound and mesh infection rates between coated and uncoated polypropylene mesh in patients undergoing open ventral hernia repair. METHODS: A prospective, institutional database at a tertiary hernia center identified patients undergoing open preperitoneal ventral hernia repair (OPPVHR) with polypropylene mesh in CDC class 1 and 2 wounds. Using propensity score matching, an absorbable, coated and uncoated group were matched based on age, comorbidities, wound class, defect size, and mesh size. RESULTS: There were 265 patients each in the matched coated and uncoated mesh groups for a total of 530 patients. Postoperative wound infections (10.9% versus 4.6%, P = 0.01) and need for IV antibiotics (10.5% versus 4.3%, P = 0.01) were significantly higher in the coated group. There was an increase in mesh infection for the coated group (3.4% versus 0.4%, P = 0.02), and of those developing a mesh infection, 60.0% eventually required mesh excision. CONCLUSIONS: Coated mesh was associated with increased postoperative wound and mesh infection following OPPVHR. An uncoated mesh should be strongly considered when placed in an extraperitoneal location.

BACKGROUND: Wound complications following abdominal wall reconstruction (AWR) in a contaminated setting are common and significantly increase the risk of hernia recurrence. The purpose of this study was to examine the effect of short-term negative pressure wound therapy (NPWT) followed by operative delayed primary closure (DPC) of the skin and subcutaneous tissue after AWR in a contaminated setting. METHODS: A prospective institutional hernia database was queried for patients who underwent NPWT-assisted DPC after contaminated AWR between 2008 and 2020. Primary outcomes included wound complication rate and reopening of the incision. A non-DPC group was created using propensity-matching. Standard descriptive statistics were used, and a univariate analysis was performed between the DPC and non-DPC groups. RESULTS: In total, 110 patients underwent DPC following AWR. The hernias were on average large (188 ± 133.6 cm2), often recurrent (81.5%), and 60.5% required a components separation. All patients had CDC Class 3 (14.5%) or 4 (85.5%) wounds and biologic mesh placed. Using CeDAR, the wound complication rate was estimated to be 66.3%. Postoperatively, 26.4% patients developed a wound complication, but only 5.5% patients required reopening of the wound. The rate of recurrence was 5.5% with mean follow-up of 22.6 ± 27.1 months. After propensity-matching, there were 73 patients each in the DPC and non-DPC groups. DPC patients had fewer overall wound complications (23.0% vs 43.9%, p = 0.02). While 4.1% of the DPC group required reopening of the incision, 20.5% of patients in the non-DPC required reopening of the incision (p = 0.005) with an average time to healing of 150 days. Hernia recurrence remained low overall (2.7% vs 5.4%, p = 0.17). CONCLUSIONS: DPC can be performed with a high rate of success in complex, contaminated AWR patients by reducing the rate of wound complications and avoiding prolonged healing times. In patients undergoing AWR in a contaminated setting, a NPWT-assisted DPC should be considered.

INTRODUCTION: Patients undergoing abdominal wall reconstruction (AWR) with concomitant panniculectomy (CP) may be at higher risk for wound complications due to the need for large incisions and tissue undermining. The aim of this study was to evaluate whether the use of closed-incision negative pressure therapy (ciNPT) decreases wound complications in AWR patients undergoing CP. METHODS: Beginning in February 2018, all patients at this institution who underwent AWR with CP received ciNPT. These patients were identified from a prospectively maintained institutional database. A standard dressing (non-NPT) group was then created in a 1:1 fashion by identifying patients who had AWR with CP immediately before the beginning of ciNPT use (2016-2018). A univariate comparison was made between the ciNPT and non-NPT groups. The primary outcome was wound complication rate; however, other perioperative outcomes, such as requirement for reoperation, were also tracked. Standard statistical methods and logistic regression were used. RESULTS: In total, 134 patients met criteria, with 67 patients each in the ciNPT and non-NPT groups. When comparing patients in the ciNPT and non-NPT groups, they were demographically similar, including body mass index, smoking, and diabetes (P < 0.05). Hernias was large on average (289.5 ± 158.2 vs 315.3 ± 197.3 cm2, P = 0.92) and predominantly recurrent (58.5% vs 72.6%, P = 0.14). Wound complications were much lower in the ciNPT group (15.6% vs 35.5%, P = 0.01), which was mainly driven by a decrease in superficial wound breakdown (3.1% vs 19.7%, P < 0.01). Patients in the ciNPT group were less likely to require a return trip to the operating room for wound complications (0.0% vs 13.3%, P < 0.01). In logistic regression, the use of ciNPT continued to correlate with reduced wound complication rates (P = 0.02). CONCLUSIONS: In AWR with CP, the use of ciNPT significantly decreased the risk of postoperative wound complications, particularly superficial wound breakdown, and lessened the need for wound-related reoperation.

INTRODUCTION: Anterior component separation (ACS) is a well-established, highly functional technique to achieve fascial closure in complex abdominal wall reconstruction (AWR). Unfortunately, ACS is also associated with an increased risk of wound complications. Perforator sparing ACS (PS-ACS) has more recently been introduced to maintain the subcutaneous perforators derived from the deep epigastric vessels. The aim of this study is to evaluate wound-related outcomes in patients undergoing open AWR after implementation of a PS-ACS technique. METHODS: A prospectively collected database were queried for patients who underwent open AWR and an ACS from 2006 to 2018. Patients who underwent PS-ACS were compared to patients undergoing ACS using standard statistical methods. Patients undergoing concomitant panniculectomy were included in the standard ACS group. RESULTS: In total, 252 patients underwent ACS, with 24 (9.5%) undergoing PS-ACS. Age and specific comorbidities were similar between groups (all p > 0.05) except for the PS-ACS groups having a higher rate of prior tobacco use (45.8% vs 19.6%, p = 0.003). Mean hernia defect area was 381.6 ± 267.0 cm2 with 64.3% recurrent hernias, and both were similar between groups (all p > 0.05). The PS-ACS group did have more complex wounds with more Ventral Hernia Working Group Grade 3 and 4 hernias (p = 0.04). OR time and length of stay were similar between groups (all p > 0.05). Despite increased complexity, wound complication rates were much lower in the PS-ACS group (20.8% vs 46.1%, p = 0.02), and all specific wound complications were lower but not statistically different. Hernia recurrence rate was similar between PS-ACS and ACS groups (4.2% vs 7.0%, p > 0.99) with mean follow-up of 27.7 ± 26.9 months. CONCLUSIONS: In complex AWR, preservation of the deep epigastric perforating vessels during ACS significantly lowers the rates of wound complications, despite its performance in more complex patients with an increased risk of infection. PS-ACS should be performed preferentially over a standard ACS whenever possible.

INTRODUCTION: In complex abdominal wall reconstruction (AWR), the role of concomitant panniculectomy has been debated due to concern for increased wound complications that impact outcomes; however, long-term outcomes and quality of life (QOL) have not been well described. The aim of our study was to evaluate the outcomes and QOL in patients undergoing AWR with panniculectomy utilizing 3D volumetric-based propensity match. METHODS: A prospective database from a tertiary referral hernia center was queried for patients undergoing open AWR. 3D CT volumetrics were analyzed and a propensity match comparing AWR patients with and without panniculectomy was created including subcutaneous fat volume (SFV). QOL was analyzed using the Carolinas Comfort Scale. RESULTS: Propensity match yielded 312 pairs, all with adequate CT imaging for volumetric analysis. The panniculectomy group had a higher BMI (p = 0.03) and were more likely female (p < 0.0001), but all other demographics and comorbidities were similar. The panniculectomy group was more likely to have undergone prior hernia repair (77% vs 64%, p < 0.001), but hernia area, SFV, and CDC wound class were similar (all p > 0.05). Requirement of component separation (61% vs 50%, p = 0.01) and mesh excision (44% vs 35%, p = 0.02) were higher in the panniculectomy group, but operative time were similar (all p ≥ 0.05). Panniculectomy patients had a higher overall wound occurrence rate (45% vs 32%, p = 0.002) which was differentiated only by a higher rate of wound breakdown (24% vs 14%, p = 0.003); all other specific wound complications were equal (all p ≥ 0.05). Hernia recurrence rates were similar (8% vs 9%, p = 0.65) with an average follow-up of 28 months. Overall QOL was equal at 2 weeks, and 1, 6, and 12 months (all p ≥ 0.05). CONCLUSIONS: Despite panniculectomy patients and their hernias being more complex, concomitant panniculectomy increased wound complications but did not negatively impact infection rates or long-term outcomes. Concomitant panniculectomy should be considered in appropriate patients to avoid two procedures.

BACKGROUND: The merits of laparoscopic (LVHR) and open preperitoneal ventral hernia repair (OPPVHR) have been debated for more than 2 decades. Our aim was to determine peri-operative and long-term outcomes in large hernias. METHODS: A prospective, institutional database at a tertiary hernia center was queried for patients undergoing LVHR and OPPVHR. One-to-one propensity score matching was performed for hernia defect size and follow-up. RESULTS: Three hundred and fifty-two LVHR and OPPVHR patients were identified with defect sizes closely matched between laparoscopic (182.0 ± 110.0 cm2) and open repairs (178.3 ± 99.8 cm2), p = 0.64. LVHR and OPPVHR patients were comparable: mean age 57.2 ± 12.1 vs 56.6 ± 12.0 years (p = 0.52), BMI: 32.9 ± 6.6 vs 32.0 ± 7.4 kg/m2 (p = 0.16), diabetes 19.0% vs 19.7% (p = 0.87), and smoking history 8.7% vs 23.0% (p < 0.001), respectively. OPPVHR had higher number of recurrent hernias (14.2% vs 44.9%, p < 0.001), longer operative time (168.1 ± 64.3 vs 186.7 ± 67.7 min, p = 0.006), and more components separation (0% vs 20.3%, p < 0.001). Mean mesh size was larger (p < 0.001) in the open group (634.4 ± 243.4 cm2 vs 841.8 ± 277.6 cm2). The hernia recurrence rates were similar (10.8% vs 9.2%, p = 0.62), with average follow-up of 39.3 ± 32.5 vs 40.0 ± 35.0 months (p = 0.89). Length of stay was higher in the OVHR cohort (5.4 ± 3.0 vs 6.3 ± 3.6 days, p < 0.001), but 30-day readmission rates (4.0% vs 6.4%, p = 0.31) were similar. Overall wound infection rate (2.9% vs 8.4%, p = 0.03) was higher in the OPPVHR group, but the mesh infection rate was similar between LVHR (1.7%) and OPPVHR (0.6%) (p = 0.33). Postoperative pain (41.1% vs 41.4%, p = 0.95) and overall QOL based on the Carolinas Comfort Scale at 6 months (p = 0.73) and 5-years (p = 0.36) were similar. CONCLUSION: Laparoscopic and open preperitoneal repair for large ventral hernias have equivalent hernia recurrence rates, postoperative pain, and QOL on long-term follow-up. Patients undergoing OPPVHR were more likely to be recurrent, complex, require components separation, and more likely to develop postoperative wound complications.

OBJECTIVES: The aim of this study was to examine the outcomes of over a decade's experience utilizing preperitoneal ventral hernia repair (PP-VHR). BACKGROUND: PP-VHR was first described by our group in 2006, and there have been no subsequent reports of outcomes with this technique. METHODS: A prospective study of all PP-VHR from January, 2004 to April, 2016 was performed. Multivariate stepwise logistic regression and Cox proportional-hazard models were used to identify predictors of wound complications and hernia recurrence, respectively. RESULTS: There were 1023 PP-VHRs. Mean age was 57.2â±â12.6 years, BMI 33.7â±â11.4âkg/m, defect size 210.0â±â221.4âcm; 23.7% had diabetes, 13.9% were smokers, 68.7% were recurrent, and 23.6% incarcerated. Component separation was required in 43.6%, and a panniculectomy was performed in 30.0%. Wound complication was present in 27.3% of patients, with 1.7% having a mesh infection. In all, there were 53 (5.2%) hernia recurrences and 36 (3.9%) in the synthetic repairs, with a mean follow-up of 27.0â±â26.4 months. On multivariate regression (odds ratio or hazard ratio, 95% confidence interval), diabetes (1.9, 1.4-3.0), panniculectomy (2.6, 1.8-3.9), and operations requiring biologic mesh were predictors of wound complications, whereas recurrent hernia repair (2.69, 1.14-6.35), biologic mesh (3.1, 1.67-5.75), and wound complications (3.01, 1.69-5.39) were predictors of hernia recurrence. CONCLUSIONS: An open PP-VHR is a very effective means to repair large, complex, and recurrent hernias resulting in a low recurrence rate. Mesh choice in VHR is important and was associated with hernia recurrence and wound complications in this population.

BACKGROUND: Component Separation (CST) typically involves incision of one or more fascial planes to generate myofascial advancement flaps to assist with fascial closure in ventral hernia repair (VHR). The aim of this study was to compare peri-operative outcomes and quality of life (QOL) after CST versus patients without CST (No-CST) in large, preperitoneal VHR (PPVHR). METHODS: A prospective, single institution hernia study examined all patients undergoing PPVHR with synthetic mesh. Emergency and contaminated operations were excluded. A case-control cohort was identified using propensity score matching for CST and No-CST. QOL was assessed using the Carolinas Comfort Scale. RESULTS: The algorithm matched 113 CST cases to 113 No-CST cases. The groups (CST vs No-CST) were similar regarding age, BMI, diabetes, smoking, defect size, mesh size, and follow-up. In univariate analysis, there was no difference in recurrence between the CST and no-CST groups (0.9% vs 0.9%, p = 1.0) or mesh infection (0.9% vs 0.0%, p = 1.0). CST did have more wound complications (29.2% vs 16.1%, p = 0.019). When controlling for panniculectomy and diabetes with multivariate logistic regression, CST continued to have had an increased risk for wound complications (OR 2.27, CI 1.16-4.47). QOL was routinely assessed. The groups were similar pre-operatively with 76.3% of CST patients and 77.8% of No-CST patients having pain (p = 1.0). At 1, 6, 12, 24, and 36 months post-operatively, the groups had equal QOL. CONCLUSION: The use of CST versus No-CST in the repair of large VHs results in an increased risk of wound complications but does not increase the hernia recurrence rate. In the largest QOL comparative study to date, CST's generation of myofascial advancement flaps does not negatively impact patient QOL in the repair of large ventral hernias in the short or long term.

OBJECTIVE: The goal of the present study was to reaffirm the psychometric properties of the CCS using an expansive, multinational cohort. BACKGROUND: The Carolinas Comfort Scale (CCS) is a validated, disease-specific, quality of life (QOL) questionnaire developed for patients undergoing hernia repair. METHODS: The data were obtained from the International Hernia Mesh Registry, an American, European, and Australian prospective, hernia repair database designed to capture information delineating patient demographics, surgical findings, and QOL using the CCS at 1, 6, 12, and 24 months postoperatively. RESULTS: A total of 3788 patients performed 11,060 postoperative surveys. Patient response rates exceeded 80% at 1 year postoperatively. Acceptability was demonstrated by an average of less than 2 missing items per survey. The formal test of reliability revealed a global Cronbach's alpha exceeding 0.95 for all hernia types. Test-retest validity was supported by the correlation found between 2 different administrations of the CCS using the kappa coefficient. Principal component analysis identified 2 components with a good distribution of variance, with the first component explaining approximately 60% of the variance, regardless of hernia type. Discriminant validity was assessed by comparing survey responses and use of pain medication at 1 month postoperatively and analysis revealed that symptomatic patients demonstrated significantly higher odds of requiring pain medication in all activity domains and for all hernia types. CONCLUSIONS: The present study confirms that the CCS questionnaire is a validated, sensitive, and robust instrument for assessing QOL after hernia repair, which has become a predominant outcome measure in this discipline of surgery.

BACKGROUND: Transabdominal, preperitoneal (TAPP), laparoscopic inguinal hernia repair (IHR) requires the creation of a peritoneal flap (PF) that must be closed after mesh placement. Our previous study indicated that sutured PF closure resulted in less short-term postoperative pain at 2 and 4 weeks compared to tacks and staples. Therefore, the aim of this follow-up study was to compare short-term QOL with a greater sample size and long-term QOL at 2 years by method of PF closure. MATERIALS AND METHODS: A prospective institutional hernia-specific database was assessed for all adult TAPP IHRs from July 2012 to May 2015. QOL outcomes were compared by PF closure method at 2 and 4 weeks and 6, 12, and 24 months as measured by the Carolinas Comfort Scale. Standard statistical tests were used for the whole population and then the Bonferroni Correction was used to compare groups (p < 0.0167). Multivariate analysis controlling for age, gender, recurrent hernias, and preoperative symptomatic pain was used to compare QOL by PF closure method. RESULTS: A total of 679 TAPP IHRs in 466 patients were analyzed; 253 were unilateral, and 213 were bilateral. PF closure was performed using tacks in 36.7 %, suture in 24.3 %, and staples in 39.0 %. There was no difference in hernia recurrence (only 1 patient at 36 months). There were no statistical differences in QOL between 2 and 4 weeks and 6- to 24-month follow-up. When resolution of symptoms from preoperative levels was examined, there was no difference in the three groups at any time point (p > 0.05). After controlling for confounding variables on multivariate analysis, there was no difference in QOL by PF closure method at any time point (p > 0.05). CONCLUSION: Tacked, sutured, and stapled techniques for peritoneal flap closure following TAPP have no significant differences in operative outcomes, postoperative quality of life, or resolution of symptoms.

INTRODUCTION: Outcomes following OVHR may be affected by type of component separation. In this study, outcomes including QOL of patients undergoing OVHR were evaluated based on the utilization of transversus abdominis release (TAR), posterior rectus sheath release (PRSR) alone or in combination with external oblique release (EOR + PRSR). METHODS: A prospective, single-institution study following open ventral hernia repair involving component separation was performed from May 2005 to April 2015. Self-reported QOL outcomes were obtained preoperatively and at 1, 6 and 12 months postoperatively using the Carolinas Comfort Scale (CCS). A CCS of 2 (mild but bothersome discomfort) or greater was considered symptomatic. Comorbidities, complications, outcomes and CCS scores were reviewed. Univariate group comparisons were performed using Chi-square and Wilcoxon two-sample tests with statistical significance set at p < 0.05. RESULTS: During the study period, 292 OVHRs with CST met inclusion criteria. Single-sided, different releases on opposite sides, etc., were eliminated. Demographics included: average age-57.9 ± 11.9 years, BMI-34.0 ± 7.9 kgm2, 53.2% female, 69% at least one prior hernia repair and average defect size-291.2 ± 236.2 cm2. Preoperative discomfort (82 vs. 75 vs. 79%, p = 0.77) and movement limitation (94 vs. 70 vs. 78%, p = 0.1) in TAR, PRSR and EOR + PRSR were similar. Average follow-up was 16.4 months. At 1, 6 and 12 months postoperatively, there was no difference in reported CCS pain scores, movement limitation or mesh sensation among the groups (p > 0.05). Comparing OVHR patients outcomes by CST type, TAR was associated with decreased wound infections compared to others (3.2 vs. 16.1 vs. 20%, p = 0.07) while recurrence rates were increased in EOR + PRSR compared to TAR and PRSR alone(8.4 vs. 3 vs. 1.8%, p = 0.03). Eighty percent of recurrences had a biologic mesh secondary to contaminated field during hernia repair. The other two recurrences were one which occurred superior to the mesh at a suture site and one who developed a wound infection postoperatively. Mesh infection rates were low (0 vs. 1.5 vs. 2.6%, p > 0.05) even including contaminated cases (0 vs. 2 vs. 3.6%, p > 0.05) and were statistically equivalent among all three techniques. CONCLUSION: While QOL is not impacted by type of component separation on short- or long-term follow-up, the TAR may provide benefits such as decreased wound infection rates. Overall QOL had a significant improvement from preoperative regardless of type of component separation. When controlling for field contamination, there were no differences in recurrence or infection.

INTRODUCTION: To reduce costs, the Centers for Medicare and Medicaid Services (CMS) implemented new policies governing which patients are automatically admitted as inpatients (staying greater than "two midnights") and which require additional justification with physician documentation to be admitted. This study examines procedures missing from the Medicare Inpatient Only (MIO) list and uses national data to evaluate its appropriateness. METHODS: Non-MIO procedures were identified from the current MIO list. Utilizing relevant billing codes, procedures were queried in the National Surgery Quality Improvement Program database for length of stay (LOS), percentage requiring >2 day stay, and inpatient status from 2005 to 2012. In addition, a separate analysis was performed for patients 65 years old or older who would qualify for Medicare. RESULTS: A majority of patients stayed more than 2 days for several procedures not included on the MIO list (% staying >2 days, mean LOS), including component separation (79.1%, 5.9 ± 12.3 days), diagnostic laparoscopy (64.2%, 5.5 ± 11.9 days), laparoscopic splenectomy (60.0%, 9.0 ± 13.6 days), open recurrent ventral hernia repair (58.2%, 6.3 ± 9.0 days), laparoscopic esophageal surgery (46.4%, 5.3 ± 13.3 days), and laparoscopic ventral hernia repair (24.7%, 2.5 ± 8.8 days). In patients ≥65 years, the average LOS was longer than the general population; for example, 40.2% of laparoscopic appendectomies and 38.7% of laparoscopic cholecystectomies in this older group required more than two nights in the hospital. In 92.3% of procedures examined, patients ≥65 years required greater than two nights in the hospital with an average LOS of 2.5-10.7 days. CONCLUSION: Commonly encountered non-MIO surgical procedures have national precedents for inpatient status.

BACKGROUND: Laparoscopy revolutionized many General Surgery procedures by decreasing hospital stay, minimizing recovery time, and reducing wound infection rates. This study evaluates the potential benefits of laparoscopic approach to peritoneal dialysis catheter (PDC) placement. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was queried for laparoscopic and open PDC placement. We evaluated patient demographics, comorbidities, operative time, length of stay (LOS), and postoperative outcomes. Univariate comparison and multivariate logistic regression analysis (MVA) adjusting for confounding factors including age, body mass index (BMI), comorbidities, and preoperative conditions were performed. RESULTS: A total of 3134 patients undergoing PDC placement were recorded in the NSQIP database between 2005 and 2012, including 2412 laparoscopic cases (LPDC) (77%) and 722 open (OPDC). Overall, the majority of cases were performed by General Surgeons (81%) with most of the remainder completed by Vascular Surgeons (16.8%). Patients undergoing LPDC versus OPDC demonstrated no significant difference in gender (54 vs. 56% males, p = 0.4), smoking history (8.5 ± 18.3 vs. 7.2 ± 16.9 pack years, p = 0.06), diabetes (42 vs. 40%, p = 0.4), COPD (4.6 vs. 5%, p = 0.63), or preoperative dialysis requirement (72 vs. 73 %, p = 0.6), but they were younger (57.2 ± 14.8 vs. 60.5 ± 15.9 years, p = 0.05) and had a higher BMI (29.3 vs. 29 kg/m(2), p = 0.04). In univariate analysis of LPDC versus OPDC, overall wound complications (1.6 vs. 2.9 %, p = 0.02), deep surgical site infections (0.12 vs. 0.83%, p < 0.006), minor complications (3.8 vs. 6.5 %, p < 0.05), major complications (4.3 vs. 6.9%, p < 0.05), and LOS (1.8 ± 11.9 vs. 4.4 ± 10 days, p < 0.0001) favored the LPDC approach, but only operative time (57.6 ± 4.6 vs. 71.8 ± 5.3, p < 0.001) remained significant in MVA after controlling for confounding factors. Both LPDC and OPDC had equivalently low rates of catheter failure (0.21 vs. 0.14%, p = 0.7). CONCLUSION: Using univariate analysis, there appears to be a benefit from LPDC placement. However, after controlling for confounding variables, the techniques appear to have equal outcomes. Surgeons should perform a LPDC or OPDC according to the approach with which they are most familiar. However, continued adoption, dispersal, and refinement of the laparoscopic approach may further optimize patient outcomes.

INTRODUCTION: Component separation (CS) has become a viable alternative to repair large ventral defects when the fascia cannot be reapproximated. However, the impact of transecting the external oblique to facilitate closure of the abdomen on quality of life (QOL) has yet to be investigated. The study goal was to investigate QOL and outcomes after standard open ventral hernia repair (OVHR) versus CS for large ventral hernias. STUDY DESIGN: Prospective data for all CSs were reviewed and compared with matched OVHR controls. All defects were 100 to 1000 cm2 in size and repaired with mesh. Comorbidities, complications, outcomes, and Carolinas Comfort Scale (CCS) scores, were reviewed. RESULTS: Seventy-four CS patients were compared with 154 patients undergoing standard OVHR with similar defect sizes. Age (56.7±13.0 vs. 54.7 ± 12.3 years, P = .26), defect sizes (299 ± 160 vs. 304 ± 210 cm2, P = .87), and BMI (32.7 ± 6.9 vs. 34.2 ± 9.0 kg/m2, P = .26) were similar in both groups, respectively. There were no differences in major postoperative complications (P = .22), mesh infections (P = 1.00), wound infections (P = .07), or hernia recurrence (P = .09), but wound breakdown increased after CS (10% vs. 1%, P < .001) as did seroma interventions (15% vs. 4%, P = .005). Postoperative CCS scores were similar at 1 month (P = .82) and 1 year (P = .14). CONCLUSIONS: In the first comparative study of its kind, it is found that patient undergoing CS with mesh reinforcement had equal short- and long-term QOL outcomes compared with similar patients who underwent standard OVHR. Whereas wound breakdown and seroma formation are higher, the overall complication, mesh infection, and recurrence rates are similar.

BACKGROUND: Creating a surgical specialty referral center requires a strong interest, expertise, and a market demand in that particular field, as well as some form of promotion. In 2004, we established a tertiary hernia referral center. Our goal in this study was to examine its impact on institutional volume and economics. MATERIALS AND METHODS: The database of all hernia repairs (2004-2011) was reviewed comparing hernia repair type and volume and center financial performance. The ventral hernia repair (VHR) patient subset was further analyzed with particular attention paid to previous repairs, comorbidities, referral patterns, and the concomitant involvement of plastic surgery. RESULTS: From 2004 to 2011, 4927 hernia repairs were performed: 39.3% inguinal, 35.5% ventral or incisional, 16.2% umbilical, 5.8% diaphragmatic, 1.6% femoral, and 1.5% other. Annual billing increased yearly from 7% to 85% and averaged 37% per year. Comparing 2004 with 2011, procedural volume increased 234%, and billing increased 713%. During that period, there was a 2.5-fold increase in open VHRs, and plastic surgeon involvement increased almost 8-fold, (P = .004). In 2005, 51 VHR patients had a previous repair, 27.0% with mesh, versus 114 previous VHR in 2011, 58.3% with mesh (P < .0001). For VHR, in-state referrals from 2004 to 2011 increased 340% while out-of-state referrals jumped 580%. In 2011, 21% of all patients had more than 4 comorbidities, significantly increased from 2004 (P = .02). CONCLUSION: The establishment of a tertiary, regional referral center for hernia repair has led to a substantial increase in surgical volume, complexity, referral geography, and financial benefit to the institution.

BACKGROUND: Administrators have focused on decreasing postoperative readmissions for cost reduction without fully understanding their preventability. This study describes the development and implementation of a surgeon-led readmission review process that assessed preventability. METHODS: A gastrointestinal surgical group at a tertiary referral hospital developed and implemented a template to analyze inpatient and outpatient readmissions. Monthly stakeholder assessments reviewed and categorized readmissions as potentially preventable or not preventable. Continuous variables were examined by the Student's t test and reported as means and standard deviations. Categorical variables were examined by the Pearson χ2 statistic and Fisher's exact test. RESULTS: There were 61 readmission events after 849 inpatient operations (7.2%) and 16 after 856 outpatient operations (1.9%), the latter of which were all classified as potentially preventable. Colorectal procedures represented 65.6% of readmissions despite being only 37.2% of all cases. The majority (67.2%) of readmission events were not preventable. Compared to the not-preventable group, the potentially preventable group experienced more dehydration (30.0% vs 9.8%, P = .045) and ileostomy creation (78.6% vs 33.3%, P = .017). The potential for outpatient management to prevent readmission was significantly higher in the potentially preventable group (40.0% vs 0.0%, P < .001), as was premature discharge prevention (35.0% vs 0.0%, P < .001). CONCLUSION: The use of the standardized template developed for analyzing readmission events after inpatient and outpatient procedures identified a disparate potential for readmission prevention. This finding suggests that a singular focus on readmission reduction is misguided, with further work needed to evaluate and implement appropriate quality-based strategies.

BACKGROUND: Flank and lumbar hernias (FLH) are challenging to repair. This study aimed to establish a reproducible management strategy and analyze elective flank and lumbar repair (FLHR) outcomes from a single institution. METHODS: A prospective analysis using a hernia-specific database was performed examining patients undergoing open FLHR between 2004 and 2021. Variables included patient demographics and operative characteristics. RESULTS: Of 142 patients, 106 presented with flank hernias, and 36 with lumbar hernias. Patients, primarily ASA Class 2 or 3, exhibited a mean age of 57.0 â± â13.4 years and BMI of 30.2 â± â5.7 âkg/m2. Repairs predominantly utilized synthetic mesh in the preperitoneal space (95.1 â%). After 29.9 â± â13.1 months follow-up, wound infections occurred in 8.3 â%; hernia recurrence was 3.5 â%. At 6 months postoperatively, 21.2 â% of patients reported chronic pain with two-thirds of these individuals having preoperative pain. CONCLUSIONS: Open preperitoneal FLHR provides a durable repair with low complication and hernia recurrence rates over 2.5 years of follow-up.

INTRODUCTION: Early after its adoption, minimally invasive surgery had limited usefulness in emergent cases. However, with improvements in equipment, techniques, and skills, laparoscopy in complex and emergency operations expanded substantially. This study aimed to examine the trend of laparoscopy in incarcerated or strangulated ventral hernia repair (VHR) over time. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for laparoscopic repair of incarcerated and strangulated hernias (LIS-VHR) and compared over 2 time periods, 2014-2016 and 2017-2019. RESULTS: The utilization of laparoscopy in all incarcerated or strangulated VHR increased over time (2014-2016: 39.9% (n = 14 075) vs 2017-2019: 46.3% (n = 18 369), P < .001). Though likely not clinically significant, demographics and comorbidities statistically differed between groups (female: 51.7% vs 50.0%, P = .003; age 54.5 ± 13.7 vs 55.4 ± 13.8 years, P < .001; BMI 34.9 ± 8.0 vs 34.6 ± 7.8 kg/m2, P < .001). Patients from 2017 to 2019 were less comorbid (18.9% vs 16.8% smokers, P < .001; 18.2% vs 17.3% diabetic, P = .036; 4.6% vs 4.1% COPD, P = .021) but had higher ASA classification (III: 43.3% vs 45.7%; IV: 2.5% vs 2.7%, P < .001). Hernia types (primary, incisional, recurrent) were similar in each group. Operative time (89.7 ± 59.3 vs 97.4 ± 63.4 min, P < .001) became longer but length-of-stay (1.4 ± 3.3 vs 1.1 ± 2.6 days, P < .001) decreased. There was no statistical difference in surgical complications, medical complications, reoperation, or readmission rates between periods. CONCLUSION: Laparoscopic VHR has become a routine method for treating incarcerated and strangulated hernias, and its utilization continues to increase over time. Clinical outcomes have remained the same while hospital stays have decreased.

INTRODUCTION: Active smoking is related to wound and respiratory complications following abdominal wall reconstruction (AWR), but no AWR studies directly compare outcomes of abstinent-smokers (AS), fulfilling four-weeks of smoking cessation, to non-smokers (NS). METHODS: Prospectively maintained institutional database was queried for all AWR between 2012 and 2019. AS and NS were included. Primary outcomes were wound and respiratory complications; secondary outcome was recurrence. Standard statistical analyses were performed. RESULTS: Evaluation included 1088 patients, 305 AS and 783 NS. AS had a lower BMI (31.3 vs 32.7 âkg/m2; P â= â0.004) but increased ASA Class III (51.5% vs 34.5 â%, P â= â0.009), COPD (8.9% vs 4.0 â%, P â= â0.001), comorbidities (6.3 vs 4.7, P < 0.001), and wound class (Class III/IV: 25.3% vs 15.8 â%, P â= â0.003). AS had increased defect size (229 vs 209.1 âcm2; P â= â0.023), use of component separation (CST) (52.5% vs 43.8 â%; P â= â0.010) and hospital stay (6.6 vs 6.2 days, P â= â0.015). Postoperative wound, mesh, and pulmonary infection, respiratory failure, and recurrence were similar. On multivariable regression, wound class and complications predicted recurrence. BMI, panniculectomy and CST predicted wound complications. BMI, CST, and wound class predicted respiratory complications. CONCLUSION: Despite greater patient and hernia complexity, smoking cessation appears to result in similar outcomes to never-smokers in this AWR population.
