Management of abdominal wall hernias in patients with severe obesity.

Obesity is a risk factor for abdominal wall hernia development and hernia recurrence. The management of these two pathologies is complex and often entwined. Bariatric and ventral hernia surgery require careful consideration of physiologic and technical components for optimal outcomes. In this review, a multidisciplinary group of Society of American Gastrointestinal and Endoscopic Surgeons' bariatric and hernia surgeons present the various weight loss modalities available for the pre-operative optimization of patients with severe obesity and concurrent hernias. The group also details the technical aspects of managing abdominal wall defects during weight loss procedures and suggests the optimal timing of definitive hernia repair after bariatric surgery. Since level one evidence is not available on some of the topics covered by this review, expert opinion was implemented in some instances. Additional high-quality research in this area will allow for better recommendations and therefore treatment strategies for these complex patients.

Gender Disparities in General Surgery Resident Subspecialization.

BACKGROUND: There are an increasing number of women entering medical school and general surgery residency. Despite this, there remains an underrepresentation of women in some surgical specialties. The purpose of this study is to examine gender differences in fellowship subspecialization of recent general surgery graduates. METHODS: Graduating residents from general surgery residencies from 2016 to 2020 were identified. Referring to each residency's graduating resident website, we noted whether or not listed alumni were reported to have entered a fellowship. If applicants were listed as having completed a fellowship, the fellowship was noted along with each applicant's expressed gender. Differences across groups were analyzed using SPSS. RESULTS: The majority (82.4%) of graduates pursued a fellowship after residency training. Men were more likely to enter fellowships in Cardiothoracic Surgery, Plastic and Reconstructive Surgery, Vascular Surgery, and practice than women. Women were more likely to enter fellowships in Breast Surgery, Acute Care Surgery/Trauma Surgery, Pediatric Surgery, and Endocrine Surgery than men. CONCLUSIONS: The majority of general surgery residency graduates pursue fellowship training. Gender disparities continue for a minority of subspecialties for both men and women.

Preparing for and passing the fundamentals of laparoscopic surgery (FLS) exam improves general surgery resident operative performance and autonomy.

BACKGROUND: The American Board of Surgery made the Fundamentals of Laparoscopic Surgery (FLS) exam a prerequisite for board certification in 2009. Some residency programs have questioned the need for a continued FLS testing mandate given limited evidence that supports the impact of FLS on intraoperative skills. The Society for Improving Medical Professional Learning (SIMPL) app is a tool to evaluate resident intraoperative performance. We hypothesized that general surgery resident operative performance would improve immediately after preparing for the FLS exam. METHODS: The national public FLS data registry was matched with SIMPL resident evaluations from 2015 to 2021 and de-identified. SIMPL evaluations are scored in three categories: supervision required (Zwisch scale 1-4, 1 = show and tell and 4 = supervision only), performance (scale 1-5, 1 = exceptional and 5 = unprepared), and case complexity (scale 1-3, 1 = easiest and 3 = hardest). Statistical analyses compared pre and post-FLS exam resident average operative evaluation scores. RESULTS: There were a total of 76 general surgery residents, and 573 resident SIMPL evaluations included in this study. Residents required more supervision in laparoscopic cases performed before compared to after the FLS exam (2.84 vs. 3.03, respectively, p = 0.007). Residents performance scores improved from cases before compared to after the FLS exam (2.70 vs. 2.43, respectively, p = 0.001). Case complexity did not differ before versus after the FLS exam (2.13 vs. 2.18, respectively, p = 0.202). PGY level significantly predicted evaluation scores with a moderate correlation. A sub analysis grouped by PGY level revealed a significant improvement after the FLS exam in supervision among PGY-2 residents (2.33 vs. 2.58, respectively, p = 0.04) and performance among PGY-4 residents (2.67 vs 2.04, respectively, p < 0.001). CONCLUSIONS: Preparation for, and passing, the FLS exam improves resident intraoperative laparoscopic performance and independence. We recommend taking the exam in the first two years of residency to enhance the laparoscopic experience for the remainder of training.

Robotic simulation: validation and qualitative assessment of a general surgery resident training curriculum.

BACKGROUND: The da Vinci skills simulation curriculum has been validated in the literature. The updated simulator, SimNow, features restructured exercises that have not been formally validated. The purpose of this study is to validate the SimNow resident robotic basic simulation curriculum. This study also consists of a qualitative assessment that gives greater insight into the learner's experience completing the robotic curriculum. METHODS: There were 18 participants in this study: 6 novices, 6 competent surgeons, and 6 expert surgeons. The curriculum comprised 5 exercises; participants completed three consecutive scored trials. Computer-derived performance metrics were recorded. The NASA Task Load Index survey was used to assess subjective mental workload. Subjects were asked a series of open-ended questions regarding their experience that were recorded and transcribed. Codes were identified using an inductive method, and themes were generated. RESULTS: Performance metrics were significantly different between novice versus competent and expert surgeons. There was no significant difference in any score metric between competent and expert surgeons. On average, overall score percentages for competent and expert surgeons were between 90.4 and 92.8% versus 70.5% for novices (p = 0.02 and p = 0.01). Expert surgeons perceived a higher level of performance completing the exercises than novice surgeons (15.8 vs. 45.8, p = 0.02). Participants noted a similar robotic experience, utilizing efficiency of motion and visual field skills. Participants agreed on exercise strengths, exercise weaknesses, and software limitations. Competent and expert surgeons were better able to assess the exercises' clinical application. CONCLUSIONS: The SimNow curriculum is a valid simulation training as part of a general surgery resident robotic curriculum. The curriculum distinguishes between novices compared to competent and expert surgeons, but not between competent and expert surgeons. Clinical training level does not affect the experience and mental workload using the robotic simulator, except for competent and expert surgeons' ability to better assess clinical application.

Long-Term, Prospective, Multicenter Study of Poly-4-Hydroxybutyrate Mesh (Phasix Mesh) for Hernia Repair in Cohort at Risk for Complication: 60-Month Follow-Up.

BACKGROUND: Long-term resorbable mesh represents a promising technology for ventral and incisional hernia repair (VIHR). This study evaluates poly-4-hydroxybutyrate mesh (P4HB; Phasix Mesh) among comorbid patients with CDC class I wounds. STUDY DESIGN: This prospective, multi-institutional study evaluated P4HB VIHR in comorbid patients with CDC class I wounds. Primary outcomes included hernia recurrence and surgical site infection. Secondary outcomes included pain, device-related adverse events, quality of life, reoperation, procedure time, and length of stay. Evaluations were scheduled at 1, 3, 6, 12, 18, 24, 30, 36, and 60 months. A time-to-event analysis (Kaplan-Meier) was performed for primary outcomes; secondary outcomes were reported as descriptive statistics. RESULTS: A total of 121 patients (46 male, 75 female) 54.7 ± 12.0 years old with a BMI of 32.2 ± 4.5 kg/m 2 underwent VIHR with P4HB Mesh (mean ± SD). Fifty-four patients (44.6%) completed the 60-month follow-up. Primary outcomes (Kaplan-Meier estimates at 60 months) included recurrence (22.0 ± 4.5%; 95% CI 11.7% to 29.4%) and surgical site infection (10.1 ± 2.8%; 95% CI 3.3 to 14.0). Secondary outcomes included seroma requiring intervention (n = 9), procedure time (167.9 ± 82.5 minutes), length of stay (5.3 ± 5.3 days), reoperation (18 of 121, 14.9%), visual analogue scale-pain (change from baseline -3.16 ± 3.35 cm at 60 months; n = 52), and Carolinas Comfort Total Score (change from baseline -24.3 ± 21.4 at 60 months; n = 52). CONCLUSIONS: Five-year outcomes after VIHR with P4HB mesh were associated with infrequent complications and durable hernia repair outcomes. This study provides a framework for anticipated long-term hernia repair outcomes when using P4HB mesh.

Auto-diuresis Predicts Return of Bowel Function.

PURPOSE: Feeding a ventral hernia repair (VHR) patient before the return of bowel function (ROBF) can lead to distention and emesis. Many patients spontaneously diurese after surgery. We hypothesized that this auto-diuresis would signal ROBF. MATERIALS AND METHODS: A total of 395 patients who underwent open, laparoscopic, or mixed VHR were evaluated for correlation between fluid status and ROBF or discharge. ROBF within 24 hours and discharge within 24 hours or 48 hours were used as outcome measures. RESULTS: Patients remained an average 3.59 days after surgery in the hospital and the average ROBF was on day 2.99. The first shift of ≥700 mL of urine predicted ROBF ( P =0.03) and discharge ( P =0.04) within 24 hours. The first shift output of ≥500 mL predicted discharge within 48 hours ( P =0.02). CONCLUSION: Auto-diuresis after surgery is correlated to ROBF and discharge. Accurate fluid measurement can predict bowel function and allow early diet and discharge.

Defining benchmarks for fellowship training in foregut surgery: a 10-year review of fellowship council index cases.

INTRODUCTION: Surgical treatment of foregut disease is a complex field that demands advanced expertise to ensure favorable outcomes for patients. To address the growing need for foregut surgeons, leaders within several national societies have become interested in developing a foregut fellowship. The aim of this study was to develop data-driven benchmarks that will aid in defining appropriate accreditation criteria for these fellowships. METHODS: We obtained case log data for Fellowship Council fellows trained from 2009-2019. We identified 78 complex foregut (non-bariatric) case codes and divided them into 5 index case categories including (1) hiatal/paraoesophageal hernia repair, (2) fundoplication, (3) esophageal myotomy, (4) major organ resection, and (5) minor organ resection. Median volumes in each index category were compared over time using Kruskall-Wallis tests. The share of cases done using open, laparoscopic, or robotic approaches were analyzed using linear regression analysis. RESULTS: For the 10 years analyzed, 1362 fellows logged 82,889 operations and 111,799 endoscopies. Median foregut cases per fellow grew significantly from 42 (IQR = 24-74) cases in 2010 to 69 (IQR = 33-106) cases in 2019. Median endoscopy volumes also grew significantly from 42 (IQR = 7-88) in 2010 to 69 (IQR 32-123) in 2019.The volume of hiatal/paraoesophageal hernia repairs increased significantly over time while volumes in the remaining 4 index categories remained stable. The share of robotic cases exhibited near perfect linear growth from 2.2% of all foregut cases in 2010 to 14.4% in 2019 (R = 0.99, p < 0.0001). Open cases exhibited linear decay from 7.2% of cases in 2010 to 4.7% of cases in 2019 (R = 0.92, p = 0.0001). Laparoscopic/thoracoscopic cases also exhibited linear decay from 90.6% of cases in 2010 to 80.9% of cases in 2019 (R = 0.98, p < 0.00001). CONCLUSIONS: FC fellows are exposed to robust volumes of foregut cases. This rich data set provides an evidence-based guide for establishing criteria for potential foregut fellowships.

Transversus abdominis plane blocks for complex abdominal wall reconstruction decrease hospital length of stay compared to epidurals.

BACKGROUND: Complex abdominal wall reconstruction for ventral and incisional hernias can be quite painful with prolonged length of stay (LOS). There are a variety of options to manage post-operative pain after a ventral hernia repair, including epidural catheters, transversus abdominis plane (TAP) blocks, and intravenous narcotic pain medications (IVPM). We hypothesized that TAP blocks with liposomal bupivacaine decrease the LOS compared to epidurals and IVPM. METHODS: A retrospective review of all patients who underwent an open ventral hernia repair with retromuscular mesh between 2016 and 2020 was conducted. LOS was used as the primary outcome. Secondary outcomes included post-operative pain and 90-day post-operative complications. RESULTS: An epidural was used in 66 patients, a TAP block with liposomal bupivacaine in 18 patients, and IVPM in 11 patients. The epidural group was noted to have a significantly longer duration of surgery (251.11 vs. 207.94 min; P < 0.05) and larger area of mesh (461.85 vs. 338.17 cm2; P < 0.05) when compared to the TAP block group. Hospital LOS was significantly shorter for the TAP block group compared to the epidural group (4.22 vs. 5.62 days; P < 0.05). There were no differences in post-operative complications between the groups. The epidural group reported significantly lower post-operative day one (POD1) pain scores measured on a 10-point scale, compared to the IVPM and TAP block groups (5.00 vs. 6.91 vs. 7.50; P < 0.05). CONCLUSION: Patients who received a TAP block for post-operative pain management had a significantly shorter length of stay compared to those patients who received an epidural. While the TAP block group reported higher POD1 pain scores, they did not have a significant difference in post-operative complications. TAP blocks with liposomal bupivacaine should be considered for post-operative pain control in complex ventral hernia repairs.

The evolution of the general surgery resident operative case experience in the era of robotic surgery.

BACKGROUND: Robotic-assisted general surgery procedures are becoming commonplace, requiring more residency programs to establish training curricula for residents. Concerns exist regarding the impact this will have on surgical residents' operative case distribution in laparoscopic and open surgery. This study aimed to analyze the impact of a growing robotic operative case volume and established robotic surgery training curriculum on the general surgery resident operative experience. METHODS: The robotic surgery training curriculum at the Medical College of Wisconsin was established in 2017. ACGME operative case logs of residents from 2014 to 2020 were analyzed to determine resident participation in open, laparoscopic, and robotic cases. Case categories included alimentary tract, abdomen, endocrine, thoracic, pediatric, and trauma. A one-way analysis of variance (ANOVA) was used to analyze overall cases, as well as participation by case type, post-graduate year (PGY) level, resident role, and institution type. Statistical significance was defined as a p value < 0.05. RESULTS: Operative case logs from 77 residents were analyzed with a total of 34,757 cases: 59.3% open, 39.6% laparoscopic, and 1.1% robotic. There was no significant change in open or laparoscopic case volumes. However, there was a 3.4% increase in robotic cases, from 2014 to 2020 (p = 0.01), specifically in foregut (4.0%, p = 0.01), intestinal (1.6%, p = 0.03), and hernia (8.3%, p = 0.003) procedures. Academic (2.8%, p = 0.01) and veterans' hospital (2.0%, p = 0.01) institutions saw a significant increase in their residents' robotic cases. The only resident role with a significant increase in robotic cases was first assistant (8.0%, p = 0.004). There was no significant difference across PGY levels by surgical approach. CONCLUSIONS: This study highlights that the growth of robotic cases has not had a detrimental effect on the resident experience with open and laparoscopic cases. As robotic cases continually increase, the impact on laparoscopic and open case volumes must be monitored to ensure a well-balanced training experience.

Robotic surgery training curricula: prevalence, perceptions, and educational experiences in general surgery residency programs.

BACKGROUND: Utilization of robotics in general surgery has increased exponentially in the past decade. The purpose of this study was to provide an updated analysis of the prevalence of robotic training curricula among general surgery residency programs across the United States. METHODS: A 19-item survey was distributed to program directors of the Association of Program Directors in Surgery email list. The survey focused on the programs' demographics, program directors' opinions of robotic surgery, and status of robotic surgery curricula. Data was compiled and analyzed using Qualtrics Survey Software, Microsoft Excel and IBM SPSS. Chi-Squared statistical significance was defined as a p value of < 0.05. RESULTS: Of the 280 program directors, 107 (38.2%) responded. Overall, 75 (70%) residency programs provided a formal robotic surgery curriculum. Regarding the importance of robotics to general surgery training, 67 (89%) programs that provided a formal robotic surgery curriculum stated it was either 'Very important' or 'Probably important' as opposed to 23 (72%) programs that did not offer a formal robotic surgery curriculum (p = 0.017). 73 of the 75 residency programs with a formal robotic surgery training curriculum answered the curriculum specific questions. 58 (79%) had been present for 3 years or less. Bedside assisting began in 62 (85%) programs as a post-graduate year (PGY) 1 or PGY2 and residents began operating on the console as a PGY2 or PGY3 in 53 (72%) programs. However, there was variability regarding the percentage of the case a senior resident actually operated on the robotic console. CONCLUSIONS: A majority of general surgery residency programs offer formal robotic surgery curricula and have been present for 3 years or less. Most residencies begin their curricula in PGY1 or PGY2 year, with an opportunity to bedside assist and operate on the robotic console in the first 3 years of residency. Operative barriers and defined milestones for general surgery trainees need to be identified.

Long-term outcome of absorbable synthetic mesh in clean ventral hernia repairs.

BACKGROUND: There are many materials available for the reinforcement of complex abdominal wall reconstruction, including permanent synthetic, biologic, and absorbable synthetic meshes. The recurrence rate of complex hernia repairs beyond 5 years has not been reported. We hypothesized that the use of absorbable synthetic mesh in clean wounds would yield favorable long-term outcomes. STUDY DESIGN: Patients who underwent open complex ventral hernia repair with clean wounds (CDC class 1) using absorbable synthetic mesh (Bio-A, Gore, Flagstaff, AZ) in the retrorectus position were retrospectively reviewed. Chart review and a validated telephone questionnaire to screen for recurrence were utilized to evaluate and document hernia recurrence. RESULTS: A total of 49 patients were included in this study. Patients were followed for recurrences for up to 105 months, with a mean follow-up time of 62.4 months (5.2 years). The total number of midline hernia recurrence was 7 out of the original 49 patients (14%). The mean and median recurrence time are 37.4 and 38.8 months, respectively. Kaplan-Meier survival analysis estimated hernia recurrence rate as 2%, 4.6%, 7.1%, 12%, 15%, and 18% at 12, 24, 36, 48, 60, and 72 months, respectively. CONCLUSION: The use of absorbable synthetic mesh in clean wound ventral hernia repair resulted in favorable long-term recurrence rates. The recurrence rate of absorbable synthetic mesh is similar to that of permanent synthetic mesh, which gives a viable option for patients in whom permanent synthetic mesh is not an option.

SAGES Advanced GI/MIS Certificate Program.

SAGES partners with the Fellowship Council (FC) to offer fellowships in MIS and flexible endoscopy. The FC has a robust accreditation process for fellowship programs; however, the FC is not able to address certification of individual graduates. This situation is similar to the structure of residencies whereby the ACGME accredits programs but individual board certification is delegated to constituent boards of the American Board of Medical Specialties (ABMS). In light of this gap, sponsoring societies have developed programs for issuing certificates to graduates of fellowship programs who have met predetermined standards. The purpose of this paper is to describe the SAGES Certificate Process for Adv GI MIS and Flexible Endoscopy Fellowships. The SAGES Certificate program was developed through a rigorous process and has undergone recent revision to modernize the certificate criteria. Research has shown that as many as 80% of general surgery graduates go on to complete additional fellowship training. Given the number of graduates who complete this subspecialty training each year, general surgery board certification may not be an appropriate final benchmark. The SAGES certificate program joins a long list of certification pathways for surgical fellowship trainees in ACGME and non-ACGME programs. In the future, SAGES plans to assess competency in all of core content domains with validated assessments.

Effect of Hernia Mesh Weights on Postoperative Patient-Related and Clinical Outcomes After Open Ventral Hernia Repair: A Randomized Clinical Trial.

Importance: Although multiple versions of polypropylene mesh devices are currently available on the market for hernia repair, few comparisons exist to guide surgeons as to which device may be preferable for certain indications. Mesh density is believed to impact patient outcomes, including rates of chronic pain and perception of mesh in the abdominal wall. Objective: To examine whether medium-weight polypropylene is associated with less pain at 1 year compared with heavy-weight mesh. Design, Setting, and Participants: This multicenter randomized clinical trial was performed from March 14, 2017, to April 17, 2019, with 1-year follow-up. Patients undergoing clean, open ventral hernia repairs with a width 20 cm or less were studied. Patients were blinded to the intervention. Interventions: Patients were randomized to receive medium-weight or heavy-weight polypropylene mesh during open ventral hernia repair. Main Outcomes and Measures: The primary outcome was pain measured with the National Institutes of Health (NIH) Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Intensity Short Form 3a. Secondary outcomes included quality of life and pain measured at 30 days, quality of life measured at 1 year, 30-day postoperative morbidity, and 1-year hernia recurrence. Results: A total of 350 patients participated in the study, with 173 randomized to receive heavy-weight polypropylene mesh (84 [48.6%] female; mean [SD] age, 59.2 [11.4] years) and 177 randomized to receive medium-weight polypropylene mesh (91 [51.4%] female; mean [SD] age, 59.3 [11.4] years). No significant differences were found in demographic characteristics (mean [SD] body mass index of 32.0 [5.4] in both groups [calculated as weight in kilograms divided by height in meters squared] and American Society of Anesthesiologists classes of 2-4 in both groups), comorbidities (122 [70.5%] vs 93 [52.5%] with hypertension, 44 [25.4%] vs 43 [24.3%] with diabetes, 17 [9.8%] vs 12 [6.8%] with chronic obstructive pulmonary disease), or operative characteristics (modified hernia grade of 2 in 130 [75.1] vs 140 [79.1] in the heavy-weight vs medium-weight mesh groups). Pain scores for patients in the heavy-weight vs medium-weight mesh groups at 30 days (46.3 vs 46.3, P = .89) and 1 year (30.7 vs 30.7, P = .59) were identical. No significant differences in quality of life (median [interquartile range] hernia-specific quality of life score at 1 year of 90.0 [67.9-96.7] vs 86.7 [65.0-93.3]; median [interquartile range] hernia-specific quality of life score at 30 days, 45.0 [24.6-73.8] vs 43.3 [28.3-65.0]) were found for the heavy-weight mesh vs medium-weight mesh groups. Composite 1-year recurrence rates for patients in the heavy-weight vs medium-weight polypropylene groups were similar (8% vs 7%, P = .79). Conclusions and Relevance: Medium-weight polypropylene did not demonstrate any patient-perceived or clinical benefit over heavy-weight polypropylene after open retromuscular ventral hernia repair. Long-term follow-up of these comparable groups will elucidate any potential differences in durability that have yet to be identified. Trial Registration: ClinicalTrials.gov Identifier: NCT03082391.

Robotic General Surgery Resident Training Curriculum: A Pilot Experience.

BACKGROUND: The purpose of this study was to report the impact of a pilot robotic general surgery resident training curriculum. MATERIALS AND METHODS: A single institution pilot robotic general surgery training curriculum was instituted in 2016. Accreditation Council for Graduate Medical Education operative case log trends, resident simulation performance, and surveys were analyzed. RESULTS: Forty-three general surgery residents participated in the robotic surgery training curriculum, 2016 to 2019. In total, 161 robotic cases were logged, increasing each academic year. Residents acted as bedside assistant in 42.9% (n=69) and as console surgeon in 57.1% (n=92). Fifteen first-year residents were surveyed on the training curriculum. On the postcurriculum survey, 100% found the curriculum to be very helpful, notably the hands-on in-service and skills simulator. CONCLUSIONS: Since the curriculum onset, residents participated in an increasing number of robotic operative cases and were actively engaged in simulation exercises. The establishment of this curriculum has facilitated the integration of resident education into the utilization of robotic technology. This study highlights the value of a formal robotic surgery curriculum for general surgery residency training.

Ten-year trends in minimally invasive hernia repair: a NSQIP database review.

BACKGROUND: Utilization of minimally invasive techniques for ventral and inguinal hernia repairs continues to rise. The purpose of this study was to provide updates on national utilization trends and wound complications of minimally invasive versus open ventral and inguinal hernia repairs. METHODS: Data were accessed from the 2006 to 2017 National Surgical Quality Improvement Program database. All CPT codes that correlated to laparoscopic and open inguinal and ventral hernia repairs were queried. The total number of cases and wound complications, including superficial surgical site infection (SSI), deep SSI, organ space SSI, and wound dehiscence, was collected for each respective CPT code and compared for each year. IBM SPSS Statistics Software and Microsoft Excel were used to collect and analyze the data. RESULTS: Between 2009 and 2017, the percentage of minimally invasive inguinal hernia repairs increased from 23.1 to 37.8%, whereas the percentage of minimally invasive ventral hernias only increased from 31.5 to 36.6%. Open inguinal hernia repairs had a wound complication rate ranging from 0.60 to 0.74%, which was double the rate of minimally invasive repairs (0.24 to 0.49%) for nearly each respective year. Minimally invasive ventral hernia repairs had total wound complication rates ranging from 0.91 to 1.37%, whereas open ventral hernias had the highest total wound complication rates ranging from 5.07 to 6.26%. CONCLUSIONS: Over the last ten years, the utilization of minimally invasive inguinal and ventral hernia repair has increased by nearly two-fold. A larger proportion of this increase has been secondary to minimally invasive inguinal compared to ventral hernia repairs. Wound complications across all techniques remained stable or improved, and remained significantly less in the minimally invasive compared to open approaches. This study highlights the continued growth of minimally invasive techniques in hernia repair over the last decade.

Prospective, multicenter study of P4HB (Phasix™) mesh for hernia repair in cohort at risk for complications: 3-Year follow-up.

BACKGROUND: This study represents a prospective, multicenter, open-label study to assess the safety, performance, and outcomes of poly-4-hydroxybutyrate (P4HB, Phasix™) mesh for primary ventral, primary incisional, or multiply-recurrent hernia in subjects at risk for complications. This study reports 3-year clinical outcomes. MATERIALS AND METHODS: P4HB mesh was implanted in 121 patients via retrorectus or onlay technique. Physical exam and/or quality of life surveys were completed at 1, 3, 6,12, 18, 24, and 36 months, with 5-year (60-month) follow-up ongoing. RESULTS: A total of n = 121 patients were implanted with P4HB mesh (n = 75 (62%) female) with a mean age of 54.7 ± 12.0 years and mean BMI of 32.2 ± 4.5 kg/m2 (±standard deviation). Comorbidities included: obesity (78.5%), active smokers (23.1%), COPD (28.1%), diabetes mellitus (33.1%), immunosuppression (8.3%), coronary artery disease (21.5%), chronic corticosteroid use (5.0%), hypo-albuminemia (2.5%), advanced age (5.0%), and renal insufficiency (0.8%). Hernias were repaired via retrorectus (n = 45, 37.2% with myofascial release (MR) or n = 43, 35.5% without MR), onlay (n = 8, 6.6% with MR or n = 24, 19.8% without MR), or not reported (n = 1, 0.8%). 82 patients (67.8%) completed 36-month follow-up. 17 patients (17.9% ± 0.4%) experienced hernia recurrence at 3 years, with n = 9 in the retrorectus group and n = 8 in the onlay group. SSI (n = 11) occurred in 9.3% ± 0.03% of patients. CONCLUSIONS: Long-term outcomes following ventral hernia repair with P4HB mesh demonstrate low recurrence rates at 3-year (36-month) postoperative time frame with no patients developing late mesh complications or requiring mesh removal. 5-year (60-month) follow-up is ongoing.

General Surgery Applicants are Interested in Global Surgery, but Does It Affect Their Rank List?

BACKGROUND: The interest of medical students and surgery residents in global surgery continues to grow. Few studies have examined how the presence of global surgery opportunities influences an applicant's decision to choose a surgical training program. We designed a survey to examine the interest in global surgery among general surgery residency applicants and the influence of a global surgery rotation on a general surgery residency applicant's rank list. METHODS: In March 2019, an online 20-question qualitative survey was administered to all general surgery applicants to a single academic institution. Results were stratified into two applicant groups; applicants from domestic or international medical schools. The survey was designed to capture demographic information, previous global rotations or experiences, future interest in global surgery opportunities, and the importance of global surgery in choosing a residency program. RESULT: s: A total of 179 (21% response rate) applicants completed the entire survey. Of the respondents 81% were interested in a global surgery rotation during residency, 56% considered a global surgery opportunity as moderately to extremely important to their residency rankings, 71% said they would rank a residency higher if it had a funded global surgery program compared to one without funding and 58% of the surveyed applicants were interested in incorporating global surgery into their future career. CONCLUSIONS: Global surgery opportunities are important to some general surgery residency applicants. A majority of applicants believe a funded global surgery would positively influence their rank list. As residency programs train residents for their future careers greater consideration needs to be given to developing global surgery opportunities.

Incoming residents' knot-tying and suturing skills: Are medical school boot camps sufficient?

INTRODUCTION: Many medical schools offer M4 boot camps to improve students' preparedness for surgical residencies. For three consecutive years, we investigated the impact of medical school boot camps on intern knot-tying and suturing skills when measured at the start of residency. METHODS: Forty-two interns completed questionnaires regarding their boot camp experiences. Their performance on knot-tying and suturing exercises was scored by three surgeons blinded to the questionnaire results. A comparison of these scores of interns with or without boot camp experiences was performed and statistical analysis applied. RESULTS: 26 of 42 (62%) interns reported boot camp training. There were no differences in scores between interns with or without a M4 boot camp experience for suturing [9.6(4.6) vs 9.8(4.1), p < 0.908], knot-tying [9.1(3.6) vs 8.4(4.1), p = 0.574], overall performance [2.0(0.6) vs 1.9(0.7), p = 0.424], and quality [2.0(0.6) vs 1.9(0.7), p = 0.665]) (mean(SD)). CONCLUSIONS: We could not demonstrate a statistically significant benefit in knot-tying and suturing skills of students who enrolled in M4 boot camp courses as measured at the start of surgical residency.

Resident perception of fundamental endoscopic skills exam: a single institution's experience.

BACKGROUND: Graduating general surgery residents are required to pass the FES exam for ABS certification. Trainees and surgery educators are interested in defining the most effective methods of exam preparation. Our aim is to define trainee perceptions, performance, and the most effective preparation methods regarding the FES exam. METHODS: General surgery residents from a single institution who completed the FES exam were identified. All participated in a flexible endoscopy rotation, and all had access to an endoscopy simulator. Residents were surveyed regarding preparation methods and exam difficulty. Descriptive statistics and a Kruskal-Wallis test were used. RESULTS: A total of 26 trainees took the FES exam with a first-time pass rate of 96.2%. Of 26 surveys administered, 21 were completed. Twenty trainees (76.9%) participated in a dedicated endoscopy curriculum. Scores were not different among those who received dedicated curricular instruction compared to those who did not (547 [IQR 539-562.5] vs. 516 [484.5-547], p = 0.1484; 535.5 [468.5-571] vs. 519 [464.75-575], p = 0.9514). Written exam difficulty was rated as 5.5 on a 10-point Likert scale, and 85.7% felt it was a fair assessment of endoscopy knowledge; skills exam difficulty was rated as 7, and 71% felt it was a fair assessment of endoscopy skills. Online FES modules, the endoscopy clinical rotation, and an exam preparation session with a faculty member were most effective for written exam preparation. The most effective skills exam preparation methods were independent simulator practice, the endoscopy clinical rotation, and a preparation session with a faculty member. The most difficult skills were loop reduction and retroflexion. Skill decay did not appear to be significant. CONCLUSIONS: A clinical endoscopy rotation, a method for independent skills practice, and faculty-mediated exam instruction appear to be effective exam preparation methods. When these are present, trainees report minimal need for dedicated exam preparation time prior to taking the FES exam.
