RESUMO
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.

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.

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.

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.

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.

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 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.

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.

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.

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.

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.

INTRODUCTION: Ventral/incisional hernia repair is a common procedure. Epidural anesthesia for post-operative pain control has been used to attempt to limit opioids. The complications associated with epidural anesthesia are starting to be recognized in open ventral hernia repair patients. METHODS: Data were abstracted from the National Surgical Quality Improvement Program (NSQIP) participant use data file for 2015. Adult patients with an open ventral hernia repair were identified. In an effort to identify complex hernias, patients who required the implantation of mesh and remained inpatient for 2 or more days were included. Patients with epidural anesthesia and general anesthesia (epidural group) were compared to those with general anesthesia alone (non-epidural). Descriptive statistics and complications were recorded and compared. RESULTS: A total of 1943 patients met inclusion criteria: 1009 patients (51.9%) in the non-epidural group and 934 (48.1%) in the epidural group. There were fewer clean cases in the epidural group (63.2%) than the non-epidural group (68.8%, p = 0.007). Otherwise, there was no difference in gender, age, body mass index, American Society of Anesthesiologists physical status, and current smoking status. There were more pulmonary emboli in the epidural group (1.39%) compared to the non-epidural group (0.50%, p = 0.04). Urinary tract infection was also significantly higher in the epidural group (3.10%) compared to the non-epidural group (1.59%, p = 0.03). Transfusions were also administered to more of the epidural patients (5.14%) compared to non-epidural patients (2.78%, p = 0.007). The rates of other post-operative complications were not statistically significant between the two groups. Total length of stay in the hospital was also greater in the epidural group (6.7 vs. 5.0 days, p < 0.0001). CONCLUSIONS: This is an association with the use of epidural anesthesia in open ventral hernia repairs and an increased incidence of pulmonary emboli, transfusions, and urinary tract infections, as well as an increased length of stay.

INTRODUCTION: The evaluation and treatment of post-operative nausea in bariatric surgery patients has not been standardized. In this patient population, nausea can have a significant impact on quality outcomes. The primary objective of this study was to determine the impact of nausea on post-operative outcomes in bariatric surgery patients. METHODS: A retrospective chart review was conducted of adult patients who underwent a primary laparoscopic Roux-en-Y gastric bypass (LRYGB) or sleeve gastrectomy (LSG) between 2014 and 2017 at a single institution. Patients with post-operative nausea were identified. Post-operative nausea was defined as patients who had nausea that was documented by multiple providers, and which interfered with their oral intake. Demographic variables were identified for patients with and without documented nausea. Univariate analyses were performed to determine the impact of post-operative nausea on patients' length of stay, readmissions, reoperations, and overall complications. RESULTS: There were 449 primary bariatric surgery patients in the study period, 197 (43.9%) LRYGB and 252 (56.1%) LSG. Of these patients, 160 (35.6%) had documented post-operative nausea. Demographic factors that contributed to post-operative nausea included African-American race and undergoing a LSG (p = 0.004 and p = 0.01, respectively). Patients who underwent a LSG had a 2.0 times increased risk of post-operative nausea compared to LRYGB (p = 0.01). Patients with documented nausea had a statistically significant increased length of stay (2.4 ± 1.9 days vs. 1.6 ± 1.0 days; p ≤ 0.01). Documented nausea patients had an increased incidence of Emergency Department visits within 30 days post-operatively (p = 0.02). CONCLUSIONS: Post-operative nausea was more likely in patients who underwent a sleeve gastrectomy. Gastric bypass and sleeve gastrectomy patients with documented nausea had an increased length of stay and Emergency Department visits. These results highlight the need for a metric to more accurately measure post-operative nausea, as well as a standardized anti-emetic treatment pathway to improve quality outcomes.

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.

BACKGROUND: Postoperative urinary retention (POUR) can impact quality outcomes, leading to urinary tract infections, longer lengths of stay, and increased healthcare costs. The incidence of POUR in bariatric patients is unknown. Our primary objective was to determine the incidence and risk factors contributing to POUR in primary bariatric surgery. METHODS: A retrospective review was conducted on patients who underwent a laparoscopic sleeve gastrectomy (LSG) or laparoscopic Roux-en-Y gastric bypass (LRYGB) from 2013 to 2017. POUR was defined as the inability to urinate postoperatively, requiring urinary catheterization. Univariate and multivariate analyses were performed on perioperative variables and their correlation with POUR. RESULTS: During the study period, 603 patients underwent surgery: 317 (52.6%) LSG and 286 (47.4%) LRYGB. Overall, 49 (8.1%) patients developed POUR. There were no significant differences in preoperative demographics between patients with and without POUR. Patients who underwent an LSG had an increased incidence of POUR compared with LRYGB (P = 0.002). In both procedures, POUR was associated with decreased neostigmine, isolated nondepolarizing muscle relaxant, and reduced intraoperative fluid. LSG and congestive heart failure, as well as LSG and body weight, were independently associated with POUR. Female patients who experienced POUR had significantly increased length of stay. CONCLUSIONS: Risk factors associated with POUR after primary bariatric surgery include LSG, less intraoperative neostigmine and intravenous fluids, and isolated nondepolarizing muscle relaxants. These risk factors can help educate patients and providers, as well as identify quality initiatives that focus on perioperative and anesthetic management to reduce POUR and length of hospital stay.

INTRODUCTION: SAGES is responsible for defining educational content for Advanced GI/MIS fellowships administered through the fellowship council (FC). In Fall 2016, to better define core content contained in these fellowships, SAGES proposed new case log criteria including minimum volumes within six defined categories. To test feasibility of these criteria, SAGES conducted a pilot study during the 2017-2018 academic year. METHODS: Advanced GI/MIS fellowship programs directors (PD's) who also held leadership roles in SAGES were invited to participate in the pilot. Fourteen programs including 17 fellows volunteered. To assess generalizability, 2016-2017 case log data for the volunteered pilot programs were compared to all other advanced GI/MIS programs (n = 92). To assess feasibility of the new criteria, pilot programs' 2017-2018 case logs were compared to 3 years of historical fellows' case logs (n = 326). Fisher's exact test was used for comparisons with p < 0.05 considered significant. RESULTS: Complete data were available for 16 pilot fellows (median 251.5 advanced MIS cases and 62.5 endoscopies per fellow). According to 2016-2017 data, pilot programs were not statistically different from non-pilot programs regarding achievement of any defined category minimum. Compared to historical controls, the 2017-2018 pilot fellows were significantly more likely to meet the defined category minimum for foregut cases and demonstrated a non-significant trend toward higher achievement of minimums for bariatrics, inguinal hernia, ventral hernia, and endoscopy. Pilot fellows were significantly less likely to meet the minimum for HPB/solid organ/colorectal/thoracic cases. Based on these data, SAGES eliminated the HPB/solid organ/colon/thoracic category and, in partnership with the FC, approved staged implementation of the remaining criteria over 3 years. CONCLUSIONS: The pilot study provided feasibility and generalizability evidence that allowed inclusion of appropriate defined categories for establishment of the new Advance GI/MIS fellowship criteria. We anticipate that the revised criteria will enhance the educational benefit of these fellowships.

BACKGROUND: There is little consensus on the ideal anatomical placement of bio-absorbable mesh. We hypothesized that retro-rectus placement of bio-absorbable mesh would significantly reduce recurrence rates when compared to intraperitoneal mesh placement. METHODS: A retrospective review was conducted of patients who underwent open complex ventral hernia repair using bio-absorbable mesh (Bio-A, Gore, Flagstaff, AZ). Patient demographics and Centers for Disease Control wound type were collected. RESULTS: A total of 81 patients were included. Seventy-four (91.4%) of these hernia repairs had mesh in the retro-rectus position, while 7 (8.6%) had intraperitoneal mesh placement. Patient demographics, including preoperative comorbidities, did not differ between groups. The retro-rectus group trended to have larger hernia defects (156.2 cm2) compared to the intraperitoneal group (63.9 cm2) (p = 0.058). Overall complications (e.g., dehiscence, wound drainage, cellulitis, sepsis) were also similar in both groups of patients. Recurrence rates in the retro-rectus and intraperitoneal group were 8.1% and 42.9%, respectively (p = 0.005). When evaluating only patients with CDC class 1 wounds, the recurrence rate in the retro-rectus group was 8.2% and the intraperitoneal group was 50% (p = 0.02). Overall, the average patient follow-up was 22 months and did not differ between groups. Both the retro-rectus and intraperitoneal groups indicated a significant (p < 0.05) improvement in quality of life from baseline. No long-term (> 7 days) antibiotics were used and no mesh implants were removed during the study. CONCLUSION: Patients who underwent open complex ventral hernia repairs with bio-absorbable mesh in the retro-rectus position experienced lower overall complication rates than those with intraperitoneal mesh placement. Despite a larger hernia defect in the retro-rectus group, recurrence rates were significantly reduced with retro-rectus placement of mesh compared to intraperitoneal placement. In addition, recurrence rates using bio-absorbable mesh in clean wounds are comparable to previously published recurrence rates with permanent mesh.

BACKGROUND: The primary objective of this study was to evaluate the utility of CRP in early identification of post-operative complications after bariatric surgery. The ability of this marker to acutely predict post-operative complications in bariatric surgery patients has not been determined. METHODS: A retrospective chart review was conducted of adult patients who underwent a primary and revisional laparoscopic Roux-en-Y gastric bypass (LRYGB) or sleeve gastrectomy (LSG) between 2013 and 2017 at a single institution. Patients were identified using the prospective Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database. CRP levels were drawn on post-operative day one per standard protocol. Univariate analyses were performed to determine the predictive impact of CRP levels on post-operative complications, readmissions, and reoperations. RESULTS: There were 275 patients who underwent bariatric surgery, 222 primary and 53 revisional. Of the 275 patients, 36 (13.1%) had a complication. Bariatric surgery patients with a post-operative complication had higher CRP levels compared to those who did not (4.8 ± 4.6 vs. 2.9 ± 2.0; p = 0.02). A CRP ≥ 5 mg/dL had a sensitivity for a complication of 27% and a specificity of 88%. There was no difference in CRP levels for patients with a 30-day reoperation or readmission. There were no mortalities. CONCLUSIONS: Bariatric surgery patients with elevated post-operative CRP levels are at increased risk for 30-day complications. The low sensitivity of a CRP ≥ 5 mg/dL suggests that a normal CRP level alone does not rule out the possibility of a post-operative complication. However, with its high specificity, there should be an elevated clinical suspicion of a post-operative complication in patients with a CRP ≥ 5 mg/dL.

BACKGROUND: Recent studies have suggested that potential aberrant alterations in the gastrointestinal microbiome contribute to the development of cardiovascular disease, specifically hypertension. Bariatric surgery produces significant sustained weight loss and hypertension resolution likely through multiple mechanisms which includes beneficial changes in the gut microbiome. We hypothesized that the type of prophylactic antibiotic given for bariatric surgery could impact the resolution rate of hypertension by altering the post-operative gastrointestinal microflora. METHODS: A retrospective analysis of adult bariatric patients who underwent Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) between 2012 and 2016 was conducted. The standard antibiotic prophylaxis was cefazolin, or clindamycin in patients with a penicillin allergy. Univariate analyses were performed comparing the differing peri-operative antibiotic treatments with resolution of hypertension at 2-week (± 1 week), 6-week (± 2 weeks), 3-month (± 2 weeks), 6-month (± 6 weeks), and 1-year (± 2 months) follow-up appointments. The criterion for resolution of hypertension was no longer requiring medication at time of follow-up. RESULTS: In total, 123 RYGB and 88 SG patients were included. No significant differences were found between cefazolin and clindamycin regarding hypertension resolution rates after SG. However, patients who underwent RYGB and received clindamycin had a significantly higher rate of hypertension resolution compared to cefazolin. This effect started at 2 weeks post-operatively (52.4% vs. 23.5% respectively, p = 0.008) and persisted up to the 1-year (57.9% vs. 44.0% respectively, p = 0.05). CONCLUSION: Prophylactic peri-operative, intravenous clindamycin was associated with significantly increased resolution of post-operative hypertension compared to cefazolin. This finding was not observed in SG patients. Future studies are needed to confirm the mechanism of action for this novel finding is due to the differing modifications of the gastrointestinal microflora after RYGB resulting from the specific peri-operative antibiotic administered.

BACKGROUND: Metabolic diseases such as obesity and diabetes are associated with changes in high-density lipoprotein (HDL) particles, including changes in particle size and protein composition, often resulting in abnormal function. Recent studies suggested that patients with non-alcoholic fatty liver disease (NAFLD), including individuals with non-alcoholic steatohepatitis (NASH), have smaller HDL particles when compared to individuals without liver pathologies. However, no studies have investigated potential changes in HDL particle protein composition in patients with NAFLD, in addition to changes related to obesity, to explore putative functional changes of HDL which may increase the risk of cardiovascular complications. METHODS: From a cohort of morbidly obese females who were diagnosed with simple steatosis (SS), NASH, or normal liver histology, we selected five matched individuals from each condition for a preliminary pilot HDL proteome analysis. HDL particles were enriched using size-exclusion chromatography, and the proteome of the resulting fraction was analyzed by liquid chromatography tandem mass spectrometry. Differences in the proteomes between the three conditions (normal, SS, NASH) were assessed using label-free quantitative analysis. Gene ontology term analysis was performed to assess the potential impact of proteomic changes on specific functions of HDL particles. RESULTS: Of the 95 proteins identified, 12 proteins showed nominally significant differences between the three conditions. Gene ontology term analysis revealed that severity of the liver pathology may significantly impact the anti-thrombotic functions of HDL particles, as suggested by changes in the abundance of HDL-associated proteins such as antithrombin III and plasminogen. CONCLUSIONS: The pilot data from this study suggest that changes in the HDL proteome may impact the functionality of HDL particles in NAFLD and NASH patients. These proteome changes may alter cardio-protective properties of HDL, potentially contributing to the increased cardiovascular disease risk in affected individuals. Further validation of these protein changes by orthogonal approaches is key to confirming the role of alterations in the HDL proteome in NAFLD and NASH. This will help elucidate the mechanistic effects of the altered HDL proteome on cardioprotective properties of HDL particles.
