Endoscopic impedance planimetry versus high-resolution manometry (HRM) for pre-operative motility evaluation in anti-reflux surgery.

INTRODUCTION: Pre-operative evaluation of patients with gastroesophageal reflux disease (GERD) includes assessment of esophageal motility. High-resolution manometry (HRM) is the gold standard; endoscopic impedance planimetry (IP) with Endoflip 2.0 is increasingly utilized in esophageal disorders of motility. We hypothesized that normal IP motility would correlate with normal HRM motility and tested this in a prospective cohort study. METHODS: Patients presenting for surgical evaluation of GERD between 9/2020 and 10/2021 were prospectively enrolled under an IRB-approved protocol. Patients with prior esophageal/gastric surgery, known motility disorders, or large paraesophageal hernias were excluded. All underwent HRM and IP, with normal motility defined by Chicago 3.0 classification for HRM and the presence of repetitive antegrade contractions for IP. Logistic regression and t test were used to analyze the data; p value < 0.05 was considered significant. RESULTS: Of 63 patients enrolled, 48 completed both IP and HRM testing. The cohort was 50% male with a median age of 52.5 [42.0, 66.0] years, mostly ASA class 1-2 (75.1%, n = 36) and had an average BMI of 31.4 ± 6.3 kg/m2. Normal motility tracings were in 62.5% of IP and 75% of HRM tests. Using HRM as the gold standard, IP detected normal motility with a sensitivity of 65.8% and a specificity of 50% (positive predictive value 83.3%, negative predictive value 27.8%). Normal IP was not statistically significant in predicting normal HRM (OR 3.182, 95% CI 0.826-12.262, p = 0.0926). Tolerability of IP was significantly better than HRM with lower rates of discomfort (10.9% vs. 93.4%, p < 0.0001) and higher willingness to repeat testing (100% vs. 47.8%, p < 0.0001). CONCLUSION: Esophageal motility testing with Endoflip 2.0 is well tolerated by patients. The low specificity (50%), poor negative predictive value (27.8%), and lack of statistically significant concordance between IP and HRM raises concern for the reliability of this test as a stand-alone replacement for HRM in the pre-operative evaluation for GERD.

Optimal Timing of Fundamentals of Endoscopic Surgery (FES) Testing in General Surgery Residency: Early Is Better.

BACKGROUND: Fundamentals of endoscopic surgery (FES) completion is mandatory for certification by the American Board of Surgery (ABS). As early simulation and competency assessment can bolster development of trainee proficiency, we sought to determine the optimal timing for FES examination by evaluating pass rates based on training level and previous endoscopic experience. METHODS: PGY2-5 residents at a university-based medical center who were novice to FES were assigned to complete FES training and testing. Training year, prior endoscopic experience, and FES exam scores were recorded with pre- and post-test surveys. RESULTS: Most residents in the program (88%) were able to complete FES training and testing within a single academic year. Most required only a single faculty-led session (88%) to feel confident to take the exam, augmented by varying numbers of independent practice sessions (50% 1-2, 19% 3-5, 27% > 5). After training, most (84%) felt confident that they would pass the exam, and 93% did so on their first attempt. While higher written exam scores were noted in the PGY5 group, there were no other statistically significant differences in overall pass rates or technical exam scores based on PGY level (p = 0.24). A number of previously completed endoscopic cases did not correlate with exam scores (p = 0.24 written, p = 0.91 technical). CONCLUSION: Fundamentals of endoscopic surgery (FES) certification can be successfully completed by junior level general surgery residents regardless of previous endoscopic experience. Moving this exam to earlier training years can benefit resident development and preparedness in the clinical setting without negatively impacting pass rates.

The effect of frailty and age on outcomes in elective paraesophageal hernia repair.

INTRODUCTION: Paraesophageal hernia repair (PEHR) is a safe and effective operation. Previous studies have described risk factors for poor peri-operative outcomes such as emergent operations or advanced patient age, and pre-operative frailty is a known risk factor in other major surgery. The goal of this retrospective cohort study was to determine if markers of frailty were predictive of poor peri-operative outcomes in elective paraesophageal hernia repair. METHODS: Patients who underwent elective PEHR between 1/2011 and 6/2022 at a single university-based institution were identified. Patient demographics, modified frailty index (mFI), and post-operative outcomes were recorded. A composite peri-operative morbidity outcome indicating the incidence of any of the following: prolonged length of stay (≥ 3 days), increased discharge level of care, and 30-day complications or readmissions was utilized for statistical analysis. Descriptive statistics and logistic regression were used to analyze the data. RESULTS: Of 547 patients who underwent elective PEHR, the mean age was 66.0 ± 12.3, and 77.1% (n = 422) were female. Median length of stay was 1 [IQR 1, 2]. ASA was 3-4 in 65.8% (n = 360) of patients. The composite outcome occurred in 32.4% (n = 177) of patients. On multivariate analysis, increasing age (OR 1.021, p = 0.02), high frailty (OR 2.02, p < 0.01), ASA 3-4 (OR 1.544, p = 0.05), and redo-PEHR (OR 1.72, p = 0.02) were each independently associated with the incidence of the composite outcome. On a regression of age for the composite outcome, a cutoff point of increased risk is identified at age 72 years old (OR 2.25, p < 0.01). CONCLUSION: High frailty and age over 72 years old each independently confer double the odds of a composite morbidity outcome that includes prolonged post-operative stay, peri-operative complications, the need for a higher level of care after elective paraesophageal hernia repair, and 30-day readmission. This provides additional information to counsel patients pre-operatively, as well as a potential opportunity for targeted pre-habilitation.

Early postoperative telehealth visit protocol implementation reduces emergency department utilization following benign foregut procedures.

INTRODUCTION: Emergency department (ED) visits and readmissions following benign foregut surgery (BFS) represent a burden on patients and the health care system. The objective of this study was to identify differences in ED visits and readmissions before and after implementation of an early postoperative telehealth visit protocol for BFS. We hypothesized that utilization of telehealth visits would be associated with reduced post-operative ED and hospital utilization. METHODS: An early postoperative telehealth protocol was initiated in 2020 at an academic medical center to provide a video conference within the first postoperative week. Consecutive elective BFS including fundoplication, Linx, paraesophageal hernia repair, and Heller myotomy performed between 2018 and 2022 were included. Outcomes included ED visits and 30-day readmission. Bivariate analyses were performed using Chi-squared testing for categorical variables. The association between telehealth visits and outcomes were evaluated using multivariable logistic regression. RESULTS: 616 patients underwent BFS during the study period. 310 (50.3%) were performed prior to the implementation of telehealth visits and 306 (49.7%) were after. 241 patients in the telehealth visit group (78.8%) completed their telehealth visit. A total of 34 patients (5.5%) had ED visits without readmission while 38 patients (6.2%) were readmitted within the first 30 days. The most common cause of ED visits and readmissions included pain (n = 18, 25%) and nausea/vomiting (n = 12, 16%). There was a significant reduction in ED visits without admission following telehealth visit implementation (7.4% vs 3.6%; OR 2.20, 95% CI 1.04-4.65, p = 0.04). There was no difference in readmission rates (6.1% versus 6.5%; OR 0.89, 95% CI 0.46-1.73, p = 0.73). The telehealth cohort had significantly lower ED visits for pain (31% vs 16.7%, p = 0.04) and nausea/vomiting (23.8% vs 6.7%, p = 0.02). DISCUSSION: Early telehealth follow-up was associated with a significant decrease in ED visits following BFS. The majority of this was attributable to a reduction in ED visits for pain, nausea, and vomiting. These results provide a possible avenue for improving quality and cost-effectiveness within this patient population.

Assessing the effects of smoking status on outcomes of elective minimally invasive paraesophageal hernia repair.

BACKGROUND: Patients are often advised on smoking cessation prior to elective surgical interventions, but the impact of active smoking on paraesophageal hernia repair (PEHR) outcomes is unclear. The objective of this cohort study was to evaluate the impact of active smoking on short-term outcomes following PEHR. METHODS: Patients who underwent elective PEHR at an academic institution between 2011 and 2022 were retrospectively reviewed. The National Surgical Quality Improvement Program (NSQIP) database from 2010 to 2021 was queried for PEHR. Patient demographics, comorbidities, and 30-day post-operative data were collected and maintained in an IRB-approved database. Cohorts were stratified by active smoking status. Primary outcomes included rates of death or serious morbidity (DSM) and radiographically identified recurrence. Bivariate and multivariable regressions were performed, and p value < 0.05 was considered statistically significant. RESULTS: 538 patients underwent elective PEHR in the single-institution cohort, of whom 5.8% (n = 31) were smokers. 77.7% (n = 394) were female, median age was 67 [IQR 59, 74] years, and median follow-up was 25.3 [IQR 3.2, 53.6] months. Rates of DSM (non-smoker 4.5% vs smoker 6.5%, p = 0.62) and hernia recurrence (33.3% vs 48.4%, p = 0.09) did not differ significantly. On multivariable analysis, smoking status was not associated with any outcome (p > 0.2). On NSQIP analysis, 38,284 PEHRs were identified, of whom 8.6% (n = 3584) were smokers. Increased DSM was observed among smokers (non-smoker 5.1%, smoker 6.2%, p = 0.004). Smoking status was independently associated with increased risk of DSM (OR 1.36, p < 0.001), respiratory complications (OR 1.94, p < 0.001), 30-day readmission (OR 1.21, p = 0.01), and discharge to higher level of care (OR 1.59, p = 0.01). No difference was seen in 30-day mortality or wound complications. CONCLUSION: Smoking status confers a small increased risk of short-term morbidity following elective PEHR without increased risk of mortality or hernia recurrence. While smoking cessation should be encouraged for all active smokers, minimally invasive PEHR in symptomatic patients should not be delayed on account of patient smoking status.

Is Robotic Console Time a Surrogate for Resident Operative Autonomy?

OBJECTIVE: Robotic-assisted surgery is an increasing part of general surgery training, but resident autonomy on the robotic platform can be hard to quantify. Robotic console time (RCT), the percentage of time the resident controls the console, may be an appropriate measure of resident operative autonomy. This study aims to characterize the correlation between objective resident RCT and subjectively scored operative autonomy. METHODS: Using a validated resident performance evaluation instrument, we collected resident operative autonomy ratings from residents and attendings performing robotic cholecystectomy (RC) and robotic inguinal hernia repair (IH) at a university-based general surgery program between 9/2020-6/2021. We then extracted RCT data from the Intuitive surgical system. Descriptive statistics, t-tests and ANOVA were performed. RESULTS: A total of 31 robotic operations (13 RC, 18 IH) performed by 4 attending surgeons and 8 residents (4 junior, 4 senior) were matched and included. 83.9% of cases were scored by both attending and resident. The average RCT per case was 35.6%(95% CI 13.0%,58.3%) for junior residents (PGY 2-3) and 59.7%(CI 51.1%,68.3%) for senior residents (PGY 4-5). The mean autonomy evaluated by residents was 3.29(CI 2.85,3.73) out of a maximum score of 5, while the mean autonomy evaluated by attendings was 4.12(CI 3.68,4.55). RCT significantly correlated with subjective evaluations of resident autonomy (r=0.61, p=0.0003). RCT also moderately correlated with resident training level (r=0.5306, p<0.0001). Neither attending robotic experience nor operation type significantly correlated with RCT or autonomy evaluation scores. CONCLUSIONS: Our study suggests that resident console time is a valid surrogate for resident operative autonomy in robotic cholecystectomy and inguinal hernia repair. RCT may be a valuable measure in objective assessment of residents' operative autonomy and training efficiency. Future investigation into how RCT correlates with subjective and objective autonomy metrics such as verbal guidance or distinguishing critical operative steps is needed to validate the study findings further.

Presence of refractory GERD-like symptoms following laparoscopic fundoplication is rarely indicative of true recurrent GERD.

BACKGROUND: Laparoscopic fundoplication (LF) is the gold standard for gastroesophageal reflux disease (GERD). Recurrent GERD is a known complication; however, the incidence of recurrent GERD-like symptoms and long-term fundoplication failure is rarely reported. Our objective was to identify the rate of recurrent pathologic GERD in patients with GERD-like symptoms following fundoplication. We hypothesized that patients with recurrent GERD-like symptoms refractory to medical management do not have evidence of fundoplication failure as indicated by a positive ambulatory pH study. METHODS: This is a retrospective cohort study of 353 consecutive patients undergoing LF for GERD between 2011 and 2017. Baseline demographics, objective testing, GERD-HRQL scores, and follow-up data were collected in a prospective database. Patients with return visits to clinic following routine post-operative visits were identified (n = 136, 38.5%), and those with a primary complaint of GERD-like symptoms (n = 56, 16%) were included. The primary outcome was the proportion of patients with a positive post-operative ambulatory pH study. Secondary outcomes included proportion of patients with symptoms managed with acid-reducing medications, time to return to clinic, and need for reoperation. P values < 0.05 were considered significant. RESULTS: Fifty-six (16%) patients returned during the study period for an evaluation of recurrent GERD-like symptoms with a median interval of 51.2 (26.2-74.7) months. Twenty-four patients (42.9%) were successfully managed expectantly or with acid-reducing medications. Thirty two (57.1%) presented with GERD-like symptoms and failure of management with medical acid suppression and underwent repeat ambulatory pH testing. Of these, only 5 (9%) were found to have a DeMeester score of > 14.7, and three (5%) underwent recurrent fundoplication. CONCLUSION: Following LF, the incidence of GERD-like symptoms refractory to PPI therapy is much higher than the incidence of recurrent pathologic acid reflux. Few patients with recurrent GI symptoms require surgical revision. Evaluation, including objective reflux testing, is critical to evaluating these symptoms.

Adherence to Surveillance Endoscopies Posteradication of Barrett's Esophagus With High-grade Dysplasia or Carcinoma In Situ.

GOALS: We aimed to evaluate factors associated with patient adherence to recommended surveillance guidelines during the first 3 years after endoscopic eradication of Barrett's esophagus (BE) with high-grade dysplasia (HGD) or T1a carcinoma in situ (CIS) and the relationship between adherence and detection of recurrence. BACKGROUND: While surveillance endoscopies after treatment of BE with HGD or T1a CIS are an important component of therapy, it is unclear whether these high-risk patients are adhering to recommended surveillance guidelines. MATERIALS AND METHODS: A total of 123 BE patients who underwent radiofrequency ablation±endoscopic mucosal resection for biopsy-proven HGD, or CIS between January 2010 and November 2018 underwent retrospective review for adherence to surveillance guidelines, patient factors related to adherence, and recurrence of dysplasia or CIS at 12, 24, and 36 months. RESULTS: Of 123 BE patients (89 HGD and 34 CIS), adherence during the first year following treatment was 26.97% for HGD patients and 41.18% for CIS patients, with increasing adherence rates in subsequent years. Patients who received 3 to 4 surveillance endoscopies in the first year posttreatment had significantly higher rates of recurrence detection than patients who received 0 to 2 surveillance endoscopies over this interval ( P =0.01). No patient factors were found to impact adherence significantly. CONCLUSIONS: Adherence to recommended surveillance intervals after endoscopic treatment of BE with HGD or CIS is low, with poor adherence during the first year associated with decreased detection of recurrence. Future studies are needed to evaluate risk factors and develop a potential intervention for poor adherence in this high-risk population.

Round Ligament Management in Female Patients Undergoing Inguinal Hernia Repair: Should We Divide or Preserve?

BACKGROUND: Although inguinal hernia repair in female patients is less common than in male patients, it remains a frequent procedure. The decision to divide or preserve the round ligament has largely been left to surgeon preference, but little data exists about its impact on outcomes. This study aimed to describe current practices for round ligament management and identify the impact of division on surgical and patient-reported outcomes. STUDY DESIGN: The 2013 to 2021 Abdominal Core Health Quality Collaborative database was queried for all female patients undergoing inguinal hernia repair with 30-day patient-reported outcome data available. Comparison groups were created based on round ligament management: round ligament division (RLD) or round ligament preservation (RLP). RESULTS: We identified 1365 female patients who underwent open (36.3%), laparoscopic (34.5%), or robotic (28.2%) repair. Most were non-recurrent (93%) and unilateral (82.6%). The round ligament was divided in 868 (63.6%) and preserved in 497 (36.4%) cases. There were no significant differences in overall complications (RLD 7.1%, RLP 5.2%, p = 0.17), reoperation (RLD 0.5%, RLP 0.2%, p = 0.4), or recurrence (RLD 0.1%, RLP 0.4%, p = 0.28). Mean European Registry for Abdominal Wall Hernias quality of life summary scores were not significantly different at 30 days (RLD 27.2, RLP 27.8) or 6 months (RLD 12.8, RLP 17.1). However, a significant difference was found in terms of mean pain-specific scores at 6 months, with lower pain scores in the RLD group (3 vs 4.7, p < 0.01), which persisted on multivariable analysis (p = 0.02). CONCLUSIONS: RLD is a common practice and is not associated with increased complications or recurrence. Although there is some evidence that RLD may result in decreased pain at 6 months, this must be balanced with potential functional complications of division that are not fully studied in this paper.

Virtual Interviews for Surgical Fellowship are an Acceptable Alternative to In-Person Interviews for Applicants and Faculty Alike.

Background: In-person interviews have traditionally been an integral part of the fellowship application process to allow faculty and applicants to interact and evaluate the intangible aspects of the matching process. COVID-19 has forced a transition away from in-person interviews to a virtual platform. This study sought to track faculty and applicant perspectives on this transition. Study Design: Prospectively collected survey data was obtained from all participants after each of 3 consecutive virtual interview days for minimally invasive surgery fellowship at a single academic institution. Results: One hundred percent (27/27 applicants and 9/9 faculty) of interview participants completed the survey. Cost (100% applicants, 77.8% faculty) was perceived as the greatest barrier to in-person interviews, and "inability to get a feel for the program/applicant" was the largest concern for virtual interviews (66.7% applicants, 88.9% faculty). After interviews, most participants strongly agreed that they were able to assess education (66.7% applicants, 77.8% faculty), clinical experience (70.4% applicants, 77.8% faculty), and research potential (70.4% applicants, 88.9% faculty) through the virtual platform. Only 44.4% of each group strongly agreed that they could assess "overall fit" equally as well. Most faculty (6/9, 66.7%), but fewer applicants (10/27, 37.0%), were willing to completely eliminate in-person interviews. Conclusion: Virtual interviews may be an acceptable alternative to in-person interviews in times of COVID-19 and beyond. Offering a virtual format may help to eliminate costs associated with in-person visits while adequately assessing the fit of a program for both applicants and faculty, though applicants still desire an in-person option.

S148: Long-term patient-reported outcomes of laparoscopic magnetic sphincter augmentation versus Nissen fundoplication: a 5-year follow-up study.

BACKGROUND: Laparoscopic magnetic sphincter augmentation (MSA) has emerged as an alternative to laparoscopic Nissen fundoplication (LNF) for the management of symptomatic gastroesophageal reflux disease (GERD). While short-term outcomes of MSA compare favorably to those of LNF, direct comparisons of long-term outcomes are lacking. We hypothesized that the long-term patient-reported outcomes of MSA would be similar to those achieved with LNF. METHODS: We tested this hypothesis in a retrospective cohort undergoing primary LNF or MSA between March 2013 and July 2015. The primary outcome was GERD-Health Related Quality of Life (GERD-HRQL) score at long-term follow-up relative to baseline. Secondary outcomes included dysphagia and bloating scores, proton-pump inhibitor (PPI) cessation, reoperations, and overall satisfaction with surgery. RESULTS: 70 patients (25 MSA, 45 LNF) met criteria for study inclusion. MSA patients had lower baseline BMI (median: 27.1 [IQR: 22.7-29.9] versus 30.4 [26.4-32.8], p = 0.02), lower total GERD-HRQL (26 [19-32] versus 34 [25-40], p = 0.02), and dysphagia (2 [0-3] versus 3 [1-4], p = 0.02) scores. Median follow-up interval exceeded 5 years (MSA: 68 [65-74]; LNF: 65 months [62-69]). Total GERD-HRQL improved from 26 to 9 after MSA (p < 0.001) and from 34 to 7.5 after LNF (p < 0.01); these scores did not differ between groups (p = 0.68). Dysphagia (MSA: 1 [0-2]; LNF: 0 [0-2], p = 0.96) and bloating (MSA: 1.5 [0.5-3.0]; LNF: 3.0 [1.0-4.0], p = 0.08) scores did not show any statistically significant differences. Device removal was performed in 4 (16%) MSA patients and reoperation in 3 (7%) LNF patients. Eighty-nine percent of LNF patients reported satisfaction with the procedure, compared to 70% of MSA patients (p = 0.09). CONCLUSIONS: MSA appears to offer similar long-term improvement in disease-specific quality of life as LNF. For MSA, there was a trend toward reduced long-term bloating compared to LNF, but need for reoperation and device removal may be associated with patient dissatisfaction.

Impact of Focused Hands-on Training Course on Practice Adoption of Advanced Endoscopic Techniques and Per-Oral Endoscopic Myotomy.

Background: Per-oral endoscopic myotomy (POEM) is a valuable tool for the treatment of foregut motility disorders. Hands-on courses are often utilized at the initial means of training in POEM. Whether such training is sufficient to allow individuals to launch an independent practice in POEM is unknown. The purpose of this study was to evaluate the successes and barriers of implementing a POEM practice after attending a hands-on course. Methods: We evaluated participants of a 2-day focused POEM training course. All participants of the course were sent a survey to assess their endoscopic practice before and after the course, concentrating on their ability to implement POEM after returning to their home institution. Results: Between 2012 and 2017, 11 POEM courses were held at our institution, with a total of 102 trainees. Fifty-five individuals responded to our survey (53.9%), most of whom were general surgeons who were already doing some therapeutic endoscopy but had not previously performed POEM. More than half (58.2%) were able to institute a POEM practice at their home institution after the course. Those that were successful in starting a POEM practice were more often those with previous advanced endoscopic experience (90.3%). Success was assisted by high rates of additional explant laboratories (43.6%) and in-person proctoring (52.4%) after completing the course. Those that did not start a POEM practice sited lack of institutional support as the main barrier, followed by problems with insurance approval, and lack of referral volume. Conclusion: Despite the complexity of the POEM procedure, a focused hands-on POEM training course is associated with a high rate of implementation of an independent POEM practice, particularly in individuals with previous advanced endoscopic experience. The largest barriers to POEM adoption are not technical factors, but rather are related to institutional and insurance factors.

Can We Identify Patients Appropriate for Same-Day Discharge After Laparoscopic Fundoplication?

Background: Patients, surgeons, and payers are interested in reducing hospital length of stay. Outpatient laparoscopic fundoplication (LF) can be done safely and cost effectively. There is low acceptance of this practice due to fear of readmission and patient dissatisfaction. Our aim was to identify factors predicting failure of same-day discharge after LF. Methods and Procedures: We simulated an outpatient setting for patients who underwent LF from 2017 to 2018 and collected the data prospectively. A perioperative pain and nausea protocol was utilized. Postoperatively, patients were given a liquid diet and oral medications, observed overnight, and then discharged after standard criteria were met. Failure was defined by the need for physician intervention after 3 hours or failure to discharge. Univariate and multivariable logistic regression analyses were performed assessing factors associated with failure. Two-sample t-test and chi-squared tests were used for significance. Results: Ninety-eight patients were included. Twenty patients failed, primarily due to the need for intravenous medications. Seven were discharged on postoperative day 1 but required physician intervention after 3 hours. Thirteen patients stayed >23 hours. Two patients were readmitted within 1 week of discharge. There was one acute recurrence, requiring reoperation, and one conversion to laparotomy. We found no statistically significant patient risk factor, comorbidity, or perioperative variable that could reliably predict failure of same-day discharge. Conclusion: This study suggests that same-day discharge after LF is safe and feasible. However, 20% of patients will unpredictably fail to meet discharge criteria.

Greatest Quality of Life Improvement in Patients With Large Ventral Hernias: An Individual Assessment of Items in the HerQLes Survey.

BACKGROUND: Ventral hernia repair (VHR) has been shown to improve overall quality of life (QOL) by the validated 12-question Hernia-Related Quality-of-Life survey (HerQLes). However, which specific aspects of quality of life are most affected by VHR have not been formally investigated. METHODS: Through retrospective analysis of the Abdominal Core Health Quality Collaborative national database, we measured the change in each individual component of the HerQLes questionnaire from a pre-operative baseline assessment to one-year postoperatively in VHR patients. RESULTS: In total, 1,875 VHR patients had completed both pre- and post-operative questionnaires from 2014-2018. They were predominately Caucasian (92.3%), 57.9 ± 12.4 Y old, and evenly gender split (50.5% male, 49.5% female, P = 0.31). Most operations were performed open (80.5%) with fewer laparoscopic (7.5%) or robotic cases (12.1%). For each of the 12 individual categories, improvement in QOL from baseline to 1-Y was found to be statistically significant (P < 0.0001). This held true with subgroup analysis of small (<2 cm), medium (2-6 cm), and large (>6 cm) hernias (P < 0.0001), though a larger improvement was seen in 8 of 12 components in hernias >6 cm (P < 0.001). Operative approach did not carry a significant effect except in medium hernias (2-6 cm), where an open approach saw a greater improvement in the "accomplish less at work" item (P = 0.02). CONCLUSIONS: VHR is associated with improvement in each of the 12 components of QOL measured in the HerQLes questionnaire, regardless of the size of their hernia. The amount of improvement, however, may be dependent on hernia size and approach.

Laparoscopic Transhiatal Esophagectomy for Invasive Esophageal Adenocarcinoma.

BACKGROUND: Esophagectomy is a fundamental step to achieve long-term disease-free survival in esophageal cancer. While various approaches have been described, there is no consensus on the single best technique to optimize operative and oncologic outcomes. We aim to report the modern experience with laparoscopic transhiatal esophagectomy (LTHE) for invasive adenocarcinoma. METHODS: We reviewed all patients who underwent LTHE with extended lymph node dissection for distal esophageal adenocarcinoma (EAC) at our institution between 2007 and 2016. Pre-operative characteristics, operative details, postoperative complications, and long-term outcomes were tracked by review of the electronic medical record and patient surveys. Survival rates were calculated with Kaplan-Meier curves. RESULTS: Eighty-two EAC patients underwent LTHE during the study period (84% male, mean age 65, mean BMI 27.8, large). Most patients were clinical stage III (42.7%) and 68.3% had received neoadjuvant chemoradiation (nCRT). Laparoscopy was successful in 93.9%, with five cases requiring conversion to open (6.1%). The median lymph node harvest was 19. Overall complication rate (major and minor) was 45.5% and ninety-day mortality was 4%. Overall 5-year survival was 52% (77% for stage 1, 57% for stage 2, 37% for stage 3). CONCLUSIONS: Laparoscopic transhiatal esophagectomy has an important role in current esophageal cancer treatment and can be performed with curative intent in patients with distal esophageal tumors. In addition to the well-known advantages of laparoscopy, the increased mediastinal visibility and a modern focus on oncologic principles seem to have a positive impact on cancer survival compared to the open transhiatal approach.

The Modern Age of POEM: the Past, Present and Future of Per-Oral Endoscopic Myotomy.

BACKGROUND: Per-oral endoscopic myotomy (POEM) has gained widespread enthusiasm amongst foregut specialists since its introduction in the mid 2000s as an effective and less invasive treatment option for achalasia. As more than 6000 POEM procedures have been performed to date throughout the world, we aim to summarize the history and current state of POEM in the treatment of esophageal motility disorders. METHODS: We performed a comprehensive review of the published literature focusing on the history and development of the POEM procedure, and its most current applications and outcomes. RESULTS: Multiple favorable long-term studies have been published advocating for the use of POEM as a valid and perhaps the most valid treatment option for achalasia. The procedure is also increasingly being applied to a wider spectrum of esophageal motility disorders including type III achalasia, spastic esophageal disease or isolated lower esophageal sphincter (LES) dysfunction, as well as new endoluminal procedures such as submucosal tumor endoscopic resection (STER), endoscopic fundoplications (POEM-F) and peroral pyloromyotomy (POP or G-POEM). CONCLUSIONS: While POEM is a proved and valid procedure, its further adoption is being threatened by external factors: challenges related to teaching, institutional support (politics) and insurance reimbursement. While this technique has come an incredible distance in its relatively short lifespan, the future of POEM in the USA will depend on the support from surgical societies to validate it as a valuable tool in the esophageal specialist's armamentarium, and to encourage a commitment to training in endoluminal surgery.

Feasibility of implementing a virtual reality program as an adjuvant tool for peri-operative pain control; Results of a randomized controlled trial in minimally invasive foregut surgery.

BACKGROUND: Post-operative pain control and narcotic over-utilization are challenging issues for surgeons in all fields. While virtual reality (VR) has been increasingly applied in various fields, its feasibility and efficacy in the peri-operative period has not been evaluated. The aim of this study was to examine the experience of an integrated VR protocol in the perioperative setting. METHODS: Patients undergoing minimally invasive foregut surgery at a single institution were randomized to receive a series of VR meditation/mindfulness sessions (VR) or to standard care after surgery (non-VR). Post-operative pain levels, narcotic utilization and patient satisfaction were tracked. RESULTS: Fifty-two patients were enrolled with 26 in each arm. Post-operative pain scores, total narcotic utilization, and overall satisfaction scores were not significantly different between the two groups. For patients in the VR arm, sessions were able to be incorporated into the perioperative routine with little disruption. Most (73.9 %) were able complete all six VR sessions and reported low pain, anxiety, and nausea scores while using the device. A high proportion responded that they would use VR again (76.2 %) or would like a VR program designed for pain (62.0 %). There were no complications from device usage. CONCLUSION: VR is a safe and simple intervention that is associated with high patient satisfaction and is feasible to implement in the perioperative setting. While the current study is underpowered to detect difference in narcotic utilization, this device holds promise as an adjuvant tool in multimodal pain and anxiety control in the peri-operative period.
