Does selective intraoperative music reduce pain following abdominal wall reconstruction? A double-blind randomized controlled trial.

PURPOSE: Although intraoperative music is purported to mitigate postoperative pain after some procedures, its application has never been explored in abdominal wall reconstruction (AWR). We sought to determine whether intraoperative music would decrease early postoperative pain following AWR. METHODS: We conducted a placebo-controlled, patient-, surgeon-, and assessor-blinded, randomized controlled trial at a single center between June 2022 and July 2023 including 321 adult patients undergoing open AWR with retromuscular mesh. Patients received noise-canceling headphones and were randomized 1:1 to patient-selected music or silence after induction, stratified by preoperative chronic opioid use. All patients received multimodal pain control. The primary outcome was pain (NRS-11) at 24 ± 3 h. The primary outcome was analyzed by linear regression with pre-specified covariates (chronic opioid use, hernia width, operative time, myofascial release, anxiety disorder diagnosis, and preoperative STAI-6 score). RESULTS: 178 patients were randomized to music, 164 of which were analyzed. 177 were randomized to silence, 157 of which were analyzed. At 24 ± 3 h postoperatively, there was no difference in the primary outcome of NRS-11 scores (5.18 ± 2.62 vs 5.27 ± 2.46, p = 0.75). After adjusting for prespecified covariates, the difference of NRS-11 scores at 24 ± 3 h between the music and silence groups remained insignificant (p = 0.83). There was no difference in NRS-11 or STAI-6 scores at 48 ± 3 and 72 ± 3 h, intraoperative sedation, or postoperative narcotic usage. CONCLUSION: For patients undergoing AWR, there was no benefit of intraoperative music over routine multimodal pain control for early postoperative pain reduction.

Incidence of clinically relevant postoperative pancreatic fistula in patients undergoing open and minimally invasive pancreatoduodenectomy: a population-based study.

Purpose: Postoperative pancreatic fistula (POPF) remains a devastating complication of pancreatoduodenectomy (PD). Minimally invasive PD (MIPD), including laparoscopic (LPD) and robotic (RPD) approaches, have comparable POPF rates to open PD (OPD). However, we hypothesize that the likelihood of having a more severe POPF, as defined as clinically relevant POPF (CR-POPF), would be higher in an MIPD relative to OPD. Methods: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) targeted pancreatectomy dataset (2014-2020) was reviewed for any POPF after OPD. Propensity score matching (PSM) compared MIPD to OPD, and then RPD to LPD. Results: Among 3,083 patients who developed a POPF, 2,843 (92.2%) underwent OPD and 240 (7.8%) MIPD; of these, 25.0% were LPD (n = 60) and 75.0% RPD (n = 180). Grade B POPF was observed in 45.4% (n = 1,400), and grade C in 6.0% (n = 185). After PSM, MIPD patients had higher rates of CR-POPF (47.3% OPD vs. 54.4% MIPD, p = 0.037), as well as higher reoperation (9.1% vs. 15.3%, p = 0.006), delayed gastric emptying (29.2% vs. 35.8%, p = 0.041), and readmission rates (28.2% vs. 35.1%, p = 0.032). However, CR-POPF rates were comparable between LPD and RPD (56.8% vs. 49.3%, p = 0.408). Conclusion: The impact of POPF is more clinically pronounced after MIPD than OPD with a more complex postoperative course. The difference appears to be attributed to the minimally invasive environment itself as no difference was noted between LPD and RPD. A clear biological explanation of this clinical observation remains missing. Further studies are warranted.

Consequences of a Surveillance Strategy for Side-Branch Intraductal Pancreatic Mucinous Neoplasms: Long-Term Follow-Up of One-Thousand Cysts.

OBJECTIVE: We aim to quantify the rate of progression in surveilled cysts and assess what factors should indicate delayed resection. SUMMARY BACKGROUND DATA: Side-branch intraductal papillary mucinous neoplasms (SB-IPMNs) are increasingly discovered, making it challenging to identify which patients require resection, thus avoiding inappropriate treatment. Most incidental lesions are surveyed, yet the consequences of that decision remain uncertain. METHODS: A prospectively maintained database of pancreatic cystic neoplasms was queried for patients with SB-IPMN. Patients with ≥2 imaging studies >6 months apart were included. Clinically relevant progression (CR-Progression) was defined by symptoms, worrisome/high-risk stigmata, or invasive cancer (IC). Growth ≥5 mm in 2 years is considered CR-Progression; size ≥3 cm alone is not. RESULTS: Between 1997-2023,1,337 patients were diagnosed with SB-IPMN. Thirty-seven (2.7%) underwent up-front surgery; 1,000 (75.0%) had >6 months surveillance.The rate of CR-progression was 15.3% (n=153) based on size increase (n=63, 6.3%), main-duct involvement (n=48, 4.8%), symptoms (n=8, 5.0%), or other criteria (n=34, 3.4%). At a median follow-up of 6.6 years (IQR 3.0-10.26), 17 patients (1.7%) developed IC. Those with CR-progression developed IC in 11.1% (n=17) and high-grade dysplasia (HGD) in 6.5% (n=10). Nearly half of the cancers were not contiguous with the surveyed SB-IPMN.Size ≥3 cm was not associated with HGD/IC (P=0.232). HGD/IC was least common in CR-progression determined by size growth (6.3%) versus main-duct involvement (24%) or other (43%, P<0.001)Patients with CR-progression demonstrated improved survival (OS) with resection on time-to-event (P<0.001) and multivariate cox-regression (HR=0.205, 0.096-0.439, P<0.001) analyses. OS was not improved with resection in all patients (P=0.244). CONCLUSION: Clinically relevant progression for SB-IPMNs is uncommon with development of cancer anywhere in the pancreas being rare. Initial size should not drive resection. Long-term and consistent non-operative surveillance is warranted, with surgery currently reserved for CR-progression knowing that the majority of these still harbor low grade pathology.

The Role of Neoadjuvant Immunotherapy in the Management of Merkel Cell Carcinoma with Clinically Detected Regional Lymph Node Metastasis.

BACKGROUND: Immunotherapy is emerging as a promising option for certain locally advanced and metastatic cutaneous malignancies. However, the role of neoadjuvant immunotherapy (NIO) in Merkel cell carcinoma (MCC) with clinically detected regional lymph node metastasis (CDRLNM) has not been fully elucidated. METHODS: For this study, MCC patients with CDRLNM who underwent surgical excision were selected from the National Cancer Database (NCDB). Those who received NIO were propensity-matched with those who did not, and Kaplan-Meier analysis was used to compare overall survival (OS). RESULTS: Of the 1809 selected patients, 356 (19.7%) received NIO followed by wide excision (n = 352, 98.9%) or amputation (n = 4, 1.1%). The rate of complete pathologic response for the primary tumor (ypT0) was 45.2%. Only 223 patents (63.4%) also underwent lymph node dissection (LND). The complete pathologic nodal response (ypN0) rate for these patients was 17.9%. A pathologic complete response of both the primary tumor and the nodal basin (ypT0 ypN0) was seen in 16 of the 223 patients who underwent both primary tumor surgery and LND. Subsequently, 151 pairs were matched between the NIO and no-NIO groups (including only patients with LND). Kaplan-Meier analysis demonstrated a significant OS improvement with NIO (median not reached vs. 35.0 ± 8.0 months; p = 0.025). The 5-year OS was 57% in the NIO group versus 44% in no-NIO group (p = 0.021). CONCLUSION: The study suggests that NIO in MCC with CDRLNM provides improved OS in addition to promising rates of primary complete response, which could change the profile of surgical resection. This supports ongoing clinical trials exploring the use of NIO in MCC.

Training Future Surgeon Leaders in Environmental Stewardship: A Review of a Decade of the Health Care Sustainability Fellowship.

OBJECTIVE: Since the inception of Ken Lee Memorial Fellowship (KLMF) in 2013, our institution has achieved 10 years of trainee led sustainability projects. The ability of health care organizations to drive sustainability depends on organizational and human capacity. This qualitative study presents the first decade of sustainability fellows' projects, the challenges associated with implementing them, and the environmental and cost impact of these initiatives. DESIGN, SETTING, PARTICIPANTS: All residents in the General Surgery residency program at the Cleveland Clinic, a quaternary hospital, regardless of postgraduate year (PGY) level, are invited to apply for the KLMF program with a short project proposal. One fellow is selected per year. Each project since the program's inception was reviewed qualitatively, relying on data derived from observation, interview of prior fellows, and supervising staff, and analysis of documentation from the annual fellow presentation and abstract, Grand Rounds recording, and fellowship leadership. RESULTS: A targeted approach by each sustainability fellow is encouraged, with the following action cycle for change implementation throughout the 1-year fellowship: identification and discovery of an issue, collaborative planning of an intervention, implementation of the intervention, and evaluation. Projects range from water and waste reduction to education of surgical staff, with positive implications for environmental stewardship in our hospital. However, multiple barriers to completing, scaling, and maintaining sustainability initiatives remain, as demonstrated by challenges faced by our Ken Lee Fellows. CONCLUSIONS: Our goal is that this intensive educational experience within the framework of a graduate medical education curriculum will ensure future generations of surgeons who are thoughtful leaders in environmental stewardship.

Sequential surgeries following transversus abdominis release for abdominal wall reconstruction: Insights from a single-center analysis.

INTRODUCTION: Abdominal surgery following transversus abdominis release (TAR) procedure commonly involves incisions through the previously implanted mesh, potentially creating vulnerabilities for hernia recurrence. Despite the popularity of the TAR procedure, current literature regarding post-AWR surgeries is limited. This study aims to reveal the incidence and outcomes of post-TAR non-hernia-related abdominal surgeries of any kind. METHODS: Adult patients who underwent non-hernia-related abdominal surgery following ventral hernia repair with concurrent TAR procedure and permanent synthetic mesh in the Cleveland Clinic Center for Abdominal Core Health between January 2014 and January 2022 were queried from a prospectively collected database in the Abdominal Core Health Quality Collaborative. We evaluated 30-day wound morbidity, perioperative complications, and long-term hernia recurrence. RESULTS: A total of 1137 patients who underwent TAR procedure were identified, with 53 patients (4.7%) undergoing subsequent non-hernia-related abdominal surgery post-TAR. Small bowel obstruction was the primary indication for reoperation (22.6%), and bowel resection was the most frequent procedure (24.5%). 49.1% of the patients required urgent or emergent surgery, with the majority (70%) having open procedures. Fascia closure was achieved by absorbable sutures in 50.9%, and of the open cases, fascia closure was achieved by running sutures technique in 35.8%. 20.8% experienced SSO, the SSOPI rate was 11.3%, and 26.4% required more than a single reoperation. A total of 88.7% were available for extended follow-up, spanning 17-30 months, resulting in a 36.1% recurrent hernia diagnosis rate. CONCLUSIONS: Abdominal surgery following TAR surgery is associated with significant comorbidities and significantly impacts hernia recurrence rates. Our study findings underscore the significance of making all efforts to minimize reoperations after TAR procedure and offers suggestions on managing the abdominal wall of these complex cases.

Natural history and growth prediction model of pancreatic serous cystic neoplasms.

OBJECTIVE: Serous cystic neoplasms (SCN) are benign pancreatic cystic neoplasms that may require resection based on local complications and rate of growth. We aimed to develop a predictive model for the growth curve of SCNs to aid in the clinical decision making of determining need for surgical resection. METHODS: Utilizing a prospectively maintained pancreatic cyst database from a single institution, patients with SCNs were identified. Diagnosis confirmation included imaging, cyst aspiration, pathology, or expert opinion. Cyst size diameter was measured by radiology or surgery. Patients with interval imaging ≥3 months from diagnosis were included. Flexible restricted cubic splines were utilized for modeling of non-linearities in time and previous measurements. Model fitting and analysis were performed using R (V3.50, Vienna, Austria) with the rms package. RESULTS: Among 203 eligible patients from 1998 to 2021, the mean initial cyst size was 31 mm (range 5-160 mm), with a mean follow-up of 72 months (range 3-266 months). The model effectively captured the non-linear relationship between cyst size and time, with both time and previous cyst size (not initial cyst size) significantly predicting current cyst growth (p < 0.01). The root mean square error for overall prediction was 10.74. Validation through bootstrapping demonstrated consistent performance, particularly for shorter follow-up intervals. CONCLUSION: SCNs typically have a similar growth rate regardless of initial size. An accurate predictive model can be used to identify rapidly growing outliers that may warrant surgical intervention, and this free model (https://riskcalc.org/SerousCystadenomaSize/) can be incorporated in the electronic medical record.

Comparing oncologic and surgical outcomes of robotic and laparoscopic pancreatoduodenectomy in patients with pancreatic cancer: a propensity-matched analysis.

INTRODUCTION: Minimally invasive Pancreatoduodenectomy (MIPD), or the Whipple procedure, is increasingly utilized. No study has compared laparoscopic (LPD) and robotic (RPD) approaches, and the impact of the learning curve on oncologic, technical, and post-operative outcomes remains relatively understudied. METHODS: The National Cancer Database was queried for patients undergoing LPD or RPD from 2010 to 2020 with a diagnosis of pancreatic cancer. Outcomes were compared between approaches using propensity-score matching (PSM); the impact of annual center-level volume of MIPD was also assessed by dividing volume into quartiles. RESULTS: A total of 3,342 patients were included. Most (n = 2,716, 81.3%) underwent LPD versus RPD (n = 626, 18.7%). There was a high rate (20.2%, n = 719) of positive margins. Mean length-of-stay (LOS) was 10.4 ± 8.9 days. Thirty-day mortality was 2.8% (n = 92) and ninety-day mortality was 5.7% (n = 189). PSM matched 625 pairs of patients receiving LPD or RPD. After PSM, there was no differences between groups based on age, sex, race, CCI, T-stage, neoadjuvant chemo/radiotherapy, or type of PD. After PSM, there was a higher rate of conversion to open (HR = 0.68, 95%CI = 0.50-0.92)., but there was no difference in LOS (HR = 1.00, 95%CI = 0.92-1.11), 30-day readmission (HR = 1.08, 95% CI = 0.68-1.71), 30-day (HR = 0.78, 95% CI = 0.39-1.56) or 90-day mortality (HR = 0.70, 95% CI = 0.42-1.16), ability to receive adjuvant therapy (HR = 1.15, 95% CI = 0.92-1.44), nodal harvest (HR = 1.01, 95%CI = 0.94-1.09) or positive margins (HR = 1.19, 95% CI = 0.89-1.59). Centers in lower quartiles of annual volume of MIPD demonstrated reduced nodal harvest (p = 0.005) and a higher rate of conversion to open (p = 0.038). Higher-volume centers had a shorter LOS (p = 0.012), higher rate of initiation of adjuvant therapy (p = 0.042), and, most strikingly, a reduction in 90-day mortality (p = 0.033). CONCLUSION: LPD and RPD have similar surgical and oncologic outcomes, with a lower rate of conversion to open in the robotic cohort. The robotic technique does not appear to eliminate the "learning curve", with higher volume centers demonstrating improved outcomes, especially seen at minimum annual volume of 5 cases.

Gender representation in the Central Surgical Association: A call to action.

BACKGROUND: Organizations such as the Central Surgical Association are important for promulgating advances in general surgery, but diversity and inclusion profoundly affect what is presented and discussed. The objective of this study was to evaluate gender representation trends at the Central Surgical Association and its annual meetings over the past 13 years. METHODS: Publicly available Central Surgical Association meeting proceedings from 2010 to 2022 were reviewed for society leaders, new members, invited speakers and moderators, and contributors to scientific sessions (first authors, senior authors). Gender identity was assessed through professional online platforms. The 2017 and 2021 meetings were conjoined with the Midwest Surgical Association. Incomplete data were obtained from 2013 and 2020-2022. RESULTS: A total of 2,158 individuals were reviewed, 554 (25.7%) of which were women. The overall trend of the absolute proportion of women participation increased by 1.8% per year (R2 = 0.7, P < .01). For leadership roles, 42/205 (20%) were women, with a 2.4% per year increase (R2 = 0.45, P = .02). For speaker roles, 82/384 (21.4%) were women, with a 2.2% increase per year (R2 = 0.6, P < .01). For scientific contributions, 253 first (35.9%) and 136 (19.3%) senior authors of 704 were women, with 1.5% (R2 = 0.4, P = .02) and 1.3% (R2 = 0.4, P = .03) increase per year, respectively. CONCLUSION: There has been a positive trend in women's involvement at Central Surgical Association meetings for leaders, speakers, and scientific authors. Diversity allows variate experiences to contribute to surgical advancements; thus, measures by the Central Surgical Association to ensure adequate representation should continue.

Paving a Path to Gender Parity: Recent Trends in Participation of Women in an Academic Surgery Society (Society for Surgery of the Alimentary Tract).

INTRODUCTION: The proportion of women surgeons is increasing, although women in surgical leadership and research has not kept pace. The Society for Surgery of the Alimentary Tract (SSAT) pledged its commitment to diversity and inclusion in 2016. Our study sought to evaluate the temporal trend of gender representation in leadership, speakership, and research at SSAT. METHODS: Publicly available SSAT meeting programs from 2010 to 2022 were reviewed to assess gender proportions within leadership positions (officers and committee chairs); invited speakerships, multidisciplinary symposia, and committee panel session moderators and speakers; and contributions to scientific sessions (moderator, first author and senior author). Verified individual professional profiles were analyzed to categorize gender as woman, man, or unavailable. Descriptive and trend analyses using linear regression and chi-squared testing were performed. RESULTS: A total of 5506 individuals were reviewed; 1178 (21.4%) were identified as women and 4328 (78.6%) as men or did not have available data. The absolute proportion of total female participation increased by 1.05% per year (R2=0.82). There was a statistically significant difference in the total proportion of women participation before and after 2016 (18.5% vs. 27.1%, p<0.01). Increases in the proportion of women were demonstrated in leadership, invited speakerships, multidisciplinary symposia, committee panel sessions, research session moderators, and abstract first authors. The proportion of women senior authors remained stagnant. CONCLUSION: Though this upward trajectory in SSAT women participation is encouraging, current trends predict that gender parity will not be reached until 2044.

Postoperative Day 1 Drain Amylase After Pancreatoduodenectomy: Optimal Level to Predict Pancreatic Fistula.

INTRODUCTION: Drain amylase on day 1 (DA-D1) after pancreaticoduodendectomy (PD) to predict occurrence of postoperative pancreatic fistula (POPF) is controversial. In this study, we evaluate the optimal DA-D1 level to predict clinically relevant POPF (CR-POPF). METHODS: The 2014-2020 NSQIP pancreatectomy-targeted database was queried for patients who underwent elective PD. Perioperative data was extracted to determine development of POPF and CR-POPF per International Study Group of Pancreatic Fistula guidelines. Receiver operative curve (ROC) and Youden's index were used to assess the performance and optimal cutoff for DA-D1 to predict CR-POPF. The DA-D1 value was confirmed with a multivariable logistic regression to determine hazard ratios (HR) for CR-POPF and conditional logistic regression by modified fistula risk score (mFRS) subgroups. RESULTS: A total of 6,087 patients with complete perioperative data were included. Mean DA-D1 was 2,897 ± 8,636 U/L; median drain duration was 5 days. CR-POPF was documented in 544 (8.9%) patients. DA-D1 ROC for CR-POPF had area under the curve of 0.779 (95%CI 0.759-0.798). Youden's index for the CR-POPF ROC coordinates had 77.6% sensitivity and 66.3% specificity, corresponding to DA-D1 values ≥ 720U/L as an optimal cutoff. CR-POPF was higher for patients with DA-D1 ≥ 720U/L (HR 4.6; p = 0.001). Patients DA-D1 < 720U/L with a negligible, low, intermediate, and high mFRS had respectively 1%, 3%, 4%, and 7% rate of CR-POPF. CONCLUSION: DA-D1 < 720U/L after elective PD is a clinically useful predictor of CR-POPF. For patients with negligible to intermediate FRS, surgeons should consider utilizing DA-D1 < 720 U/L for removal of a drain on the first postoperative day.

Female Representation at the Association of Program Directors in Surgery Annual Meeting: Moving Towards Gender Equality.

OBJECTIVE: This study aims to evaluate the state and changes over time of female representation in Association of Program Directors in Surgery (APDS) leadership and annual meeting presenters and session leaders. DESIGN, SETTING, AND PARTICIPANTS: APDS conference programs from 2013 to 2022 were reviewed to identify society leadership and meeting presenters and session leaders. Verified online profiles were used to gather professional role and reported gender. Descriptive statistics and t-tests compared female representation in the first half (2013-2017, prior) and second half of data (2018-2022, current). RESULTS: Leadership of APDS was an average 22% women, increasing from 13% in 2013 to 37% in 2022, and significantly increased from prior to current period (p = 0.0004). Conference presenters and session leaders were 42% women overall, increasing from 30% in 2013 to 52% in 2022. An average 33% staff surgeons, 54% trainees, 64% education scientists, and 51% medical student participants were female. Staff were 44% female in 2022 from 24% in 2013, significantly increased from prior to current period (p = 0.021). Comparing prior and current period cohorts, female presenters for paper sessions increased from 38% to 55% (p = 0.011), moderators from 15% to 39% (p = 0.046), and last author listed on presentation sessions from 18% to 32% (p = 0.010), while panelists, workshop directors, and presenters at all sessions increased without statistical significance. Female poster presenters decreased over time. CONCLUSIONS: Female representation at APDS meetings has increased over time. Women are well represented compared to the 2022 member population of 36% women. While positions typically held by more senior members, such as leadership, panelists, moderators, and last authors remain lower than other roles, increases over time are encouraging. APDS female representation compares favorably to many other surgical societies. Translation of successful practices regarding gender representation utilized by APDS to other surgical organizations could expedite progress toward gender parity in the field.

Cholecystoenteric Stent-Related Complications: Rendering the Inoperable Patient Operable.

INTRODUCTION: Cholecystoenteric stenting is an alternative treatment for cholecystitis. However, complications with this approach can render a need for surgical intervention. METHODS: A case series of three patients undergoing surgery for a cholecystoenteric stent-related complication. RESULTS: Patient 1 was a 42-year-old male with history of lung transplant who had a cholecystoenteric stent placed for acalculous cholecystitis. One year later the stent became occluded with return of symptoms. Endoscopic replacement failed. A laparoscopic cholecystectomy with modified Graham patch was performed. Patient 2 is a 73-year-old female with acalculous cholecystitis in the setting of metastatic colon cancer on FOLFOX. Antibiotic treatment failed. A cholecystoenteric stent was attempted, but the stent dislodged during deployment. The fistula tract was clipped, and a percutaneous cholecystostomy drain was placed, which noted a leak at the gallbladder infundibulum. The patient deteriorated clinically and was taken emergently for an open cholecystectomy. Patient 3 was a 71-year-old male with history of ischemic cardiomyopathy who had a cholecystogastric stent placed for necrotizing gallstone pancreatitis. The stent migrated into the gastrointestinal tract and he developed post-prandial pain. A cholecystectomy and modified Graham patch repair of the gastrotomy was performed. This failed as the gastrotomy was too close to the pylorus. He underwent re-operation with Heineke-Mikulicz pyloroplasty. All patients recovered without any cardiopulmonary complications. CONCLUSION: With the increasing utility of cholecystoenteric stents, surgeons should be aware of the complications and have a plan for managing the duodenotomy or gastrotomy. Shared-medical decision-making involving surgeons should be applied when placing these stents.

The role of minimally invasive surgery in resectable distal pancreatic adenocarcinoma.

BACKGROUND: In distal pancreatectomy (DP) for pancreatic ductal adenocarcinoma (PDAC), we hypothesize that minimally invasive DP (MIDP) carries short-term benefits over ODP (ODP) in the absence of postoperative pancreatic fistula (POPF). METHODS: NSQIP database was queried to select patients who underwent DP for PDAC with available report on POPF. The population was divided into No-POPF vs. POPF groups. In each group, propensity-score matching was applied to compare 30-day outcomes of ODP vs. MIDP. RESULTS: There were 2,824 patients; 2,332 (82%) had No-POPF and 492 (21%) had POPF. In No-POPF patients, 921 pairs were matched between ODP and MIDP. MIDP patients had slightly longer operations (227 vs. 205 minutes; p < 0.001), but lower rates of surgical site complications (1% vs. 2.9%; p = 0.002), postoperative transfusion (7.1% vs. 11.0%; p = 0.003), overall morbidity (21.1% vs. 26.3%; p = 0.009), and one-day shorter median length of stay (LOS) (5 vs. 6 days; p = 0.001). In the POPF group, 172 pairs were matched. There was no difference in morbidity, mortality, reoperation, LOS, and home discharge. Similar conclusions were drawn in the intention-to-treat and per-protocol analyses. CONCLUSION: POPF is common following DP for PDAC. In the absence of POPF, MIDP is associated with fewer postoperative morbidities and shorter LOS.

Distressed community index as a predictor of presentation and postoperative outcomes in ventral hernia repair.

BACKGROUND: We evaluated the impact of socioeconomic status on presentation, management, and outcomes of ventral hernias. METHODS: The Abdominal Core Health Quality Collaborative was queried for adult patients undergoing ventral hernia repair. Socioeconomic quintiles were assigned using the Distressed Community Index (DCI): prosperous (0-20), comfortable (21-40), mid-tier (41-60), at-risk (61-80), and distressed (81-100). Outcomes included presenting symptoms, urgency, operative details, 30-day outcomes, and one-year hernia recurrence rates. Multivariable regression evaluated 30-day wound complications. RESULTS: 39,494 subjects were identified; 32,471 had zip codes (82.2%).Urgent presentation (3.6% vs. 2.3%) and contaminated cases (0.83% vs. 2.06%) were more common in the distressed group compared to the prosperous group (p < 0.001). Higher DCI correlated with readmission (distressed: 4.7% vs prosperous: 2.9%,p < 0.001) and reoperation (distressed 1.8% vs prosperous: 0.92%,p < 0.001). Wound complications were independently associated with increasing DCI (p < 0.05). Clinical recurrence rates were similar at one-year (distressed: 10.4% vs prosperous: 8.6%, p = 0.54). CONCLUSIONS: Inequity exists in presentation and perioperative outcomes for ventral hernia repair and efforts should be focused on increasing access to elective surgery and improving postoperative wound care.
