Defining a High-Quality and Effective Morbidity and Mortality Conference: A Systematic Review.

Importance: Morbidity and mortality conferences (MMCs) are thought to advance trainee education, quality improvement (QI), and faculty development. However, there is considerable variability with regard to their completion. Objective: To compile and analyze the literature describing the format, design, and other attributes of MMCs that appear to best advance their stated objectives related to QI and practitioner education. Evidence Review: For this systematic review, a literature search with terms combining conference and QI or morbidity and mortality was performed in January 2022, using the PubMed, Embase, and ERIC (Education Resources Information Center) databases with no date restrictions. Included studies were published in English and described surgical or nonsurgical MMCs with explicit reference to quality or system improvement, education, professional development, or patient outcomes; these studies were classified by design as survey based, intervention based, or other methodologies. For survey-based studies, positively and negatively regarded attributes of conference design, format, and completion were extracted. For intervention-based studies, details of the intervention and their impact on stated MMC objectives were abstracted. Principal study findings were summarized for the other group. Study quality was assessed using the Medical Education Research Study Quality Instrument (MERSQI). Abstract screening, full-text review, and data extraction and analysis were completed between January 2022 and December 2022. Findings: A total of 59 studies met appropriateness for study inclusion. The mean MERSQI score for the included studies was 6.7 (range, 5.0-9.5) of a maximum possible 18, which implied that the studies were of average quality. The evidence suggested that preparation and postconference follow-up regarding QI initiatives are equally as important as both (1) succinctly presenting case details, opportunities for improvement, and educational topics and (2) creating a constructive space for accountability, engagement, and multistakeholder discussion. Conclusions and Relevance: These findings suggest that the published literature on MMCs provides substantial insight into the optimal format, design, and related attributes of an effective MMC. This systematic review provides a road map for surgical departments to improve MMCs in order to align their format and design with their principal objectives related to practitioner and trainee education, error prevention, and QI.

Intern Experience Reflects Information Gathered During the Virtual Interview Process.

OBJECTIVE: The onset of the coronavirus 2019 (COVID-19) pandemic brought many changes to the residency application process including transitioning to a virtual interview platform, which continues today. The transition brought many concerns from general surgery applicants about their ability to obtain adequate information about a program virtually. We sought to characterize how information presented by programs during the first ever virtual interview cycle matched the experience of general surgery interns after training at a program for 1 year. DESIGN, SETTING, AND PARTICIPANTS: In May of 2022, a survey was distributed to 243 program directors who were asked to forward it to their general surgery categorical interns who matched during the 2021 virtual match cycle. Demographics, resources used to determine an impression of a program, and correlations between information presented virtually and what was subsequently experienced as an intern were collected. RESULTS: Forty-six program directors confirmed forwarding the survey to their categorical interns. A total of 102 general surgery interns completed the survey. Most interns (88.2%) agreed that their experience matched expectations based on information received through the virtual interview process and 98% of interns were satisfied with their experience at their training program. Interviews with faculty (40.0%), residents (68.0%) and the program web site (29.0%) were the top 3 resources used to create the most accurate impression of a program. Interns felt they were well informed during the virtual interview experience about support from fellow residents (84.3%), culture (73.0%), surgical volume (72.5%), and intern operative experience (71.6%). In addition, 65.7% of participants thought they were able to obtain a good understanding of the program's culture from the virtual process. However, 16.7% thought that their program unintentionally misrepresented aspects of the training program. CONCLUSIONS: The faculty and residency interviews were the most important factors in program ranking and most participants agreed that their virtual interview experience matched their expectations during their intern year. Most interns felt they were able to obtain a good understanding of the program's culture from the virtual process. In addition, a majority of interns felt well informed during the interview on aspects ranging from surgical volume, autonomy, and work hours to support from faculty and residents. If virtual interviews are to continue, residents can be satisfied that information gathered virtually will match the reality of their training. Programs should continue to make every effort to present their program realistically.

Our Efforts to Create a Welcoming Surgical Residency for LGBTQ Trainees.

OBJECTIVE: To provide a more welcoming environment for LGBTQ residents. DESIGN: This paper is based upon the authors experience creating a training program welcoming to LGBTQ residents. SETTING: University General Surgery Training Program. PARTICIPANTS: Surgical Residents and Surgical Faculty. RESULTS: Over a 9 year period, our residency has made intentional efforts to welcome LGBTQ applicants and support LGBTQ residents. We now have a residency in which over 25% of our residents identify as LGBTQ. CONCLUSIONS: We see opportunities for other residencies to signal to applicants and trainees that they are welcome and celebrated for who they are.

Creating a Welcoming Surgery Residency Training Program for LGBTQ Trainees.

General Surgery residencies have been perceived as unwelcoming to lesbian, gay, bisexual, transgender, and queer (LGBTQ) applicants. Historically, applicants have been reluctant to reveal their LGBTQ status when interviewing for residency positions and LGBTQ surgery residents are more likely to consider leaving their residency. Despite the increased acceptance in society and calls for diversity by governing bodies, there is a perception that the field of surgery is lagging behind. In this article, we summarize the recent literature concerning LGBTQ status in surgery residencies and the impact it has on students and trainees. We then review the recent calls to action to remedy the identified shortcomings. We then share what has been done by our surgery residency, which has been successful in recruiting LGBTQ-identifying residents and summarize recommendation for moving forward.

The impact of English proficiency on outcomes after bariatric surgery.

BACKGROUND: Several studies demonstrated language that discordant care between may lead to mixed outcomes and increased use of hospital-resources. In the setting of bariatric surgery, which relies heavily on intensive pre-operative and post-operative counseling, we hypothesized that patients with LEP would have less favorable outcomes compared to English-proficient (EP) patients. METHODS: All patients 18 years and older, who underwent laparoscopic sleeve gastrectomy (SG) or laparoscopic gastric bypass (LGBP) from January 2013 to December 2017 were included. Language proficiency was determined by chart review for the use of an interpreter at least once during the study period. Outcomes of interest at 30-days and 1 year included: emergency department (ED) visits, readmission, length of stay (LOS), chief-complaint on readmission, and post-operative complications. Additionally, comorbidity remission and weight loss at one year was recorded. RESULTS: A total of 671 patients were categorized as LEP (40%) and spoke 6 unique languages. Within the 1 year post-operative period, EP patients presented to the ED more than LEP patients (23% vs. 14% p < 0.001). After multivariable regression for potential confounders this difference persisted; adjusted OR = 0.65 (95% CI 0.43-0.95; p = 0.029). However, despite more frequent ED visits by EP patients, there was no significant difference in readmission within one year; adjusted OR = 0.94 (95% CI 0.56-1.55; p = 0.50). Both groups demonstrated similar successful weight loss at 1 year: EP-31.85% (LGBP) and - 28.02% (SG) vs. LEP-30.17% (LGBP) and - 28.36% (SG). EP and LEP patients also had similar remission of obesity-related comorbidities. CONCLUSION: There were no differences in outcomes following bariatric surgery when comparing patients with limited English proficiency to those who are proficient in English. Bariatric surgical care can be delivered in a safe and effective manner with equivalent outcomes between patients who are and are not English-language proficient.

Application of the Caprini Risk Assessment Model to Select Patients for Extended Thromboembolism Prophylaxis After Sleeve Gastrectomy.

BACKGROUND: The Caprini risk assessment model is a well-validated tool that identifies patients who would benefit from extended venous thromboembolism (VTE) prophylaxis beyond hospital discharge. VTE, particularly portal mesenteric vein thrombosis (PMVT), is a potentially devastating complication of laparoscopic sleeve gastrectomy (LSG); therefore, we sought to examine whether the model can be safely applied to LSG patients. We hypothesized that its use can minimize the incidence of postoperative VTE, including PMVT, without increasing the likelihood of bleeding complications. MATERIALS AND METHODS: We conducted a retrospective chart review of those patients who underwent LSG at our institution from 2010 and 2018, at which time the Caprini risk assessment model was already our institutional standard. We determined the patients' Caprini scores at the time of discharge and whether patients at high risk of VTE were discharged from hospital on extended courses of VTE prophylaxis. We also recorded if bleeding complications or VTE events occurred in the first 180 days after LSG. RESULTS: Six hundred thirty-eight patients underwent LSG, including 521 (81.7%) women, with an average preoperative body mass index (BMI) of 44.4 kg/m2 (SD 6.8). One hundred fifty-eight (24.8%) patients had Caprini scores that warranted extended courses of VTE prophylaxis beyond hospital discharge. Three patients (0.47%) developed a postoperative VTE, but no patient developed PMVT. No bleeding complications were observed among patients who received extended VTE prophylaxis. CONCLUSION: The Caprini risk assessment model can effectively identify patients after LSG who might benefit from extended courses of VTE prophylaxis. Extended VTE prophylaxis does not seem to confer increased bleeding risk in this patient population.

Structuring Research Rotations to Facilitate Surgery Residents' Academic Productivity.

OBJECTIVE: We sought to enhance opportunities for general surgery residents to conduct research during residency without having to take dedicated time out of clinical training. To this end, we created structured research rotations to facilitate and support resident research. DESIGN: Research blocks of four week's duration were introduced for categorical interns and post-graduate year (PGY) 4 residents. Interns had no clinical responsibilities during their research blocks while PGY 4 residents shadowed their mentor in the clinical setting. Research projects were developed and prepared in advance to maximize productivity during the research rotation. SETTING: General surgery residency program at an urban, academic, safety-net, tertiary care hospital PARTICIPANTS: Categorical general surgery interns and PGY 4 general surgery residents RESULTS: The research rotations were first offered in the 2019 to 2020 academic year (AY). 10 interns and 11 PGY 4 residents have since completed the rotations; of the PGY 4 residents, 6 had not previously taken any time off for research activities. Research projects varied between residents and focused on basic science, clinical outcomes, quality improvement, and education. CONCLUSIONS: Through establishment of dedicated research rotations, we were able to increase resident engagement in a variety of research activities. We provide a simple model for training programs seeking increased research engagement and productivity for their residents without extending training time.

Impact of fellow compared to resident assistance on outcomes of minimally invasive surgery.

INTRODUCTION: As fellowship training after general surgery residency has become increasingly common, the impact on resident education must be considered. Patient safety and procedure outcomes are often used as justification by attendings who favor fellows over residents in certain minimally invasive surgery (MIS) operations. The aim of the present study was to compare the impact of trainee level on the outcomes of selected MIS operations to determine if giving preference to fellows on grounds of outcomes is warranted. METHODS: Patients who underwent elective laparoscopic hiatal hernia repair (LHHR), laparoscopic sleeve gastrectomy (LSG), laparoscopic Roux-en-Y gastric bypass (LRYGB), laparoscopic splenectomy (LS), laparoscopic cholecystectomy (LC), or laparoscopic ventral hernia repair (LVHR) with assistance of a general surgery chief resident or fellow were identified from the American College of Surgeon's National Surgical Quality Improvement Program database (2007-2012). Patients were matched 1:1 based on propensity score for the odds of undergoing operations assisted by a fellow. RESULTS: 5145 patients underwent LHHR, 1396 LSG, 9656 LRYGB, 863 LS, 13,434 LC, and 3069 LVHR. Fellows assisted in 41.7% of LHHR, 49.2% of LSG, 56.4% of LRYGB, 25.7% of LS, 17.1% of LC, and 27.0% of LVHR cases. After matching, overall and severe complication rates were comparable between cases performed with assistance of a fellow or chief resident. Median operative time was longer for LSG, LRYGB, and LC when a fellow assisted. CONCLUSIONS: Surgical outcomes were similar between fellow and chief resident assistance in MIS operations, arguing that increased resident participation in basic and complex laparoscopic operations is appropriate without compromising patient safety.

Teaching assistant cases in general surgery training - A literature review.

BACKGROUND: There is a lack of understanding of the scope and purpose of teaching assistant cases, impact on patients and safety, as well as the facilitators or barriers to resident participation in these cases. METHODS: Four databases (PubMed, Embase, Web of Science, and the Education Resources Information Center), were searched. The references of identified resources were additionally hand-searched. 10 articles were identified and considered in the literature review. RESULTS: The TA case literature focuses on case numbers and safety. The discussions of papers allude to perceived benefits of TA cases. The literature review reveals that residents are more likely to be granted TA opportunities if they show themselves worthy of entrustment. CONCLUSIONS: The work elucidates aspects of TA cases that have not previously been emphasized or highlighted. The literature review can serve to inform attending surgeons and trainees how to optimize the opportunities teaching assistant cases can afford.

Efficacy of a resident-as-teacher program (RATP) for general surgery residents: An evaluation of 3 Years of implementation.

BACKGROUND: Teaching is a responsibility of general surgery residents and formal teaching instruction is mandated. This study examines the efficacy of a formal RATP incorporated into our general surgery residency curriculum. METHODS: The RATP was developed locally and delivered longitudinally over the course of the academic year, starting in 2017. Self-assessment surveys were distributed to residents before and after completion of the program each academic year. Medical students were surveyed regarding their impression of teaching on the surgical clerkship. RESULTS: RATP data was collected annually. All sessions were highly rated. Residents reported improved teaching self-efficacy after participation. Medical student agreement with the statement 'Residents provided effective teaching during the [surgery] clerkship' increased from 68.6% prior to RATP implementation to 79.7% in the following years (p < 0.05). CONCLUSIONS: Incorporation of a locally developed RATP improved residents' self-perceptions and medical student perception of residents as teachers. RATPs should be adopted widely.

Association of Bariatric Surgery With Vascular Outcomes.

Importance: Bariatric surgical weight loss is associated with reduced cardiovascular mortality; however, the mechanisms underlying this association are incompletely understood. Objectives: To identify variables associated with vascular remodeling after bariatric surgery and to examine how sex, race, and metabolic status are associated with microvascular and macrovascular outcomes. Design, Setting, and Participants: This population-based longitudinal cohort included 307 individuals who underwent bariatric surgery. Participants were enrolled in the bariatric weight loss program at Boston Medical Center, a large, multi-ethnic urban hospital, with presurgical and postsurgical assessments. Data were collected from December 11, 2001 to August 27, 2019. Data were analyzed in September 2019. Exposure: Bariatric surgery. Main Outcomes and Measures: Flow-mediated dilation (FMD) and reactive hyperemia (RH) (as measures of macrovascular and microvascular function, respectively) and clinical variables were measured preoperatively at baseline and at least once postoperatively within 12 months of the bariatric intervention. Results: A total of 307 participants with obesity (mean [SD] age, 42 [12] years; 246 [80%] women; 199 [65%] White; mean [SD] body mass index, 46 [8]) were enrolled in this study. Bariatric surgery was associated with significant weight loss and improved macrovascular and microvascular function across subgroups of sex, race, and traditional metabolic syndrome (mean [SD] pre- vs postsurgery weight: 126 [25] kg vs 104 [25] kg; P < .001; mean [SD] pre- vs postsurgery FMD: 9.1% [5.3] vs 10.2% [5.1]; P < .001; mean [SD] pre- vs postsurgery RH: 764% [400] vs 923% [412]; P < .001). Factors associated with change in vascular phenotype correlated most strongly with adiposity markers and several metabolic variables depending on vascular territory (eg, association of weight change with change in RH: estimate, -3.2; 95% CI, -4.7 to -1.8; association of hemoglobin A1c with change in FMD: estimate, -0.5; 95% CI, -0.95 to -0.05). While changes in macrovascular function among individuals with metabolically healthy obesity were not observed, the addition of biomarker assessment using high-sensitivity C-reactive protein plasma levels greater than 2 mg/dL identified participants with seemingly metabolically healthy obesity who had low-grade inflammation and achieved microvascular benefit from weight loss surgery. Conclusions and Relevance: The findings of this study suggest that bariatric intervention is associated with weight loss and favorable remodeling of the vasculature among a wide range of individuals with cardiovascular risk. Moreover, differences in arterial responses to weight loss surgery by metabolic status were identified, underscoring heterogeneity in physiological responses to adiposity change and potential activation of distinct pathological pathways in clinical subgroups. As such, individuals with metabolically healthy obesity represent a mixed population that may benefit from more refined phenotypic classification.

Outcomes in Laparoscopic Roux-en-Y Gastric Bypass and Implications for Surgical Resident Education.

OBJECTIVES: Some surgery residents feel inadequately prepared to perform advanced operations, partly due to losing operative opportunities to fellows. In turn, they are prompted to pursue fellowships. Allowing residents the opportunity to participate in advanced procedures and complex cases may alleviate this cycle, if their participation is safe. This study examined the effects of resident participation in laparoscopic Roux-en-Y gastric bypass procedures (LRYGBs). DESIGN: Our MBSAQIP database was used to identify LRYGBs performed at our institution between 2015 and 2018. Operative notes were reviewed to determine training level of the assistant. Patient comorbidities and outcomes (duration of surgery, length of stay, post-operative complications, readmissions, and reoperations) were stratified by assistant level of training for comparison. SETTING: Urban tertiary care hospital. PARTICIPANTS: Trainees and attending surgeons acting as assistants during LRYGBs. RESULTS: Among 987 total cases, the assistants for the procedures were chief residents (n = 549, 56%), fourth-year residents (n = 258, 26%), attending surgeons (n = 143, 14%), and third-year residents (n = 37, 4%). Attending surgeons assisted more often when patients had a BMI ≥ 45 (38% attendings vs. 25% residents, p = 0.007), ≥ 2 comorbidities (54% vs. 40%, p = 0.007), or had a history of prior bariatric surgery (22% vs. 3%, p < 0.0001).Post-operative complication rate was low (4%) and did not differ significantly between all training levels (p = 0.86). Average length of stay, readmission rates, and reoperation rates were not significantly different across training levels (p = 0.75, p = 0.072, and p = 0.91 respectively). CONCLUSION: Complication rates, hospital length of stay, readmission rates, and reoperation rates were equivalent for patients regardless of the level of training of the assistant for LRYGBs. Involving residents in complex bariatric procedures such as LRYGB is a safe model of education that does not compromise patient safety or hospital outcomes. Involvement in advanced cases allows general surgery residents to more confidently move toward independent practice.

Surgical management of obstructing clot at the jejunojejunostomy after gastric bypass: a single center experience and literature review.

BACKGROUND: Roux-en-Y gastric bypass is a proven treatment for morbid obesity and its sequelae. Gastric bypass has a safe risk profile, but postoperative complications can be seen. We report on 10 cases of postoperative bleeding causing an obstructing clot at the jejunojejunostomy (JJ) occurring over a 9-year period. OBJECTIVES: The aim was to document presenting symptoms of obstructing clots at the JJ and to suggest a treatment approach to minimize complications. SETTING: University Hospital, United States METHODS: The local Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database was queried for all patients undergoing reoperation after Roux-en-Y gastric bypass, from July 2009 until December 2019. All patients who were found to have postoperative bleeding causing an obstructing clot at the JJ were selected for retrospective medical-record review. RESULTS: The most common presenting symptoms were Hematocrit drop (10 of 10), nausea (9 of 10), abdominal pain (7 of 10), and hematemesis (4 of 10). There were 12 reoperations in the 10 patients, 10 of which were completed laparoscopically. Infectious complications were the most frequent morbidity in our patients; 4 patients developed abscesses. In all of these, the operative notes described gross spillage into the peritoneal cavity. In later cases, the remnant stomach was decompressed before reoperation, reducing spillage. CONCLUSIONS: Despite the low rate of obstructing clots at the JJ, without rapid recognition and reoperation, there is a risk for serious complications. Typical presenting symptoms include nausea and abdominal pain, which help differentiate it from other causes of decreased hematocrit. Diagnosis is commonly made with computerized tomographic (CT) scan. Decompression of a dilated remnant stomach before addressing the clot can prevent intraperitoneal spillage and subsequent abscess formation. Enterotomy creation and removal of clot is recommended, without fear of continued bleeding.

A Structured Mentorship Elective Deepens Personal Connections and Increases Scholarly Achievements of Senior Surgery Residents.

OBJECTIVES: Surgery residents have few opportunities to work closely with attending surgeons or conduct research during clinical time. We hypothesized that a mentorship elective with a required research project would benefit residents' career development, including their personal connections with faculty mentors, and would help them build their academic portfolio. DESIGN: We created a mentorship elective designed as a one-on-one apprenticeship. Completion of a scholarly project was a core component of the elective. Residents, faculty, and the most senior resident ('non-mentee') on the same service as the elective resident were interviewed after the completion of their rotation. SETTING: University-based surgery residency at Boston Medical Center, Boston, MA. PARTICIPANTS: All 5 residents in postgraduate year 4 (PGY-4) participated in the mentorship elective during the 2019 to 2020 academic year. Residents identified their faculty mentor. All mentees (5/5), most mentors (4/5), and all non-mentees (4/4) were interviewed. RESULTS: All mentees reported interacting with their mentor daily, performing clinical duties or discussing their research project. For mentees, the top factor when selecting their mentor was the mentor's clinical expertise, and the most valuable aspect of the rotation was developing a relationship with their mentor. All mentors responded that their mentee gained an understanding of running an academic surgical practice and developed research skills. Four of 5 mentees completed critical portions of their scholarly project during the elective with one publishing in a peer-reviewed journal, 2 having their work accepted to a national conference, and one creating vascular surgery educational videos. All stated the elective was valuable. CONCLUSIONS: A structured apprenticeship rotation allowed for closer relationships with attending surgeons and increased the scholarly achievement of PGY-4 surgery residents. We provide an example of how to incorporate a successful elective rotation into the surgery curriculum that strengthens resident career development and research productivity.

Novel Low-Cost, Low-Fidelity Hemorrhoidectomy Task Trainers.

OBJECTIVE: Develop and describe a set of low-cost hemorrhoidectomy task trainer prototypes in the setting of inadequate junior resident surgical skill preparation for anorectal cases. DESIGN: This is a study comparing expert and novice performance and opinions. Three task trainers were developed to simulate dissecting, knot-tying, and suturing in a confined space, like the anus. Participants were asked to dissect the peel off of an orange, tie seven 2-handed knots on a weight, and close a defect in a piece of felt with a running stitch. An 8-oz mason jar was used to simulate the confined space. Participants were asked to fill out a 5-point Likert-based evaluation regarding the skills. The primary outcome was time to complete each task in seconds. Secondary outcome measures were number of errors associated with each task, subjective achievability of tasks, and utility of tasks for improving surgical skills. SETTING: General surgery residency program at a safety-net academic center. PARTICIPANTS: Forty subjects participated in this study. There were 20 experts (7 attending surgeons, 13 PGY-1-PGY-5 surgical residents) and 20 novices (11 third- and 9 fourth-year medical students). RESULTS: Experts knot-tied (59s vs 140s, p < 0.001) and sutured (219s vs 295s, p < 0.001) faster than novices. Experts were able to tie 7 knots in fewer attempts than novices (p < 0.001). There was no significant difference in speed of orange dissection between groups. There were no significant differences in the number or frequency of other errors. All participants felt the tasks were achievable (4.90/5) and would be useful in improving skills (4.93/5). CONCLUSIONS: This study demonstrated that a set of low-cost, low-fidelity prototypical hemorrhoidectomy task trainers can discriminate between experts and novices. Simulation models such as these can offer useful practice opportunities for junior general surgery trainees.

Surgical site occurrences, not body mass index, increase the long-term risk of ventral hernia recurrence.

BACKGROUND: Recurrence rates after ventral hernia repair vary widely and evidence about risk factors for recurrence are conflicting. There is little evidence for risk factors for long-term recurrence. METHODS: Patients who underwent ventral hernia repair at our institution and were captured in the American College of Surgeons-National Surgical Quality Improvement Program database between 2002 and 2015 were included. We reviewed all demographic, procedural, and hernia-specific data. RESULTS: Six hundred and thirty patients were included for analysis with a median follow-up of 4.9 years (inter-quartile range, 2-7.3 years). By univariate analysis, index hernia repairs were more likely to recur if defect size was ≥4 cm (P = .019), no mesh was used (P = .026), or if the repair was for a recurrent hernia (P = .001). Five-year cumulative incidence of recurrence and reoperation was 24.3% and 16.0%, respectively. Patients with a perioperative surgical site occurrence, which included superficial, deep-incisional, and organ space surgical site infections as well as wound disruption, had a 5-year cumulative incidence of recurrence of 54.9% compared with 22.6% for those without surgical site occurrence. By multivariable analysis, non-primary hernia repair (hazard ratio 1.7, 95% confidence interval 1.2-2.4, P = .005) and any postoperative surgical site occurrence (hazard ratio 1.9, 95% confidence interval 1.1-3.6, P = .02) were the only risk factors predictive of recurrence. Patient body mass index had no independent effect on recurrence. CONCLUSION: 1 in 4 patients undergoing an open ventral hernia repair will have a recurrence after 5 years, and this risk is doubled among patients who experience any perioperative surgical site occurrence. After controlling for patient comorbidities, including body mass index, hernia size, and mesh position, the most significant risk factor for recurrence after ventral hernia repair was a non-primary hernia and surgical site occurrence.
