RESUMEN
BACKGROUND & AIMS: Antireflux treatment is recommended to reduce esophageal adenocarcinoma in patients with Barrett's esophagus. Antireflux surgery (fundoplication) counteracts gastroesophageal reflux of all types of carcinogenic gastric content and reduces esophageal acid exposure to a greater extent than antireflux medication (eg, proton pump inhibitors). We examined the hypothesis that antireflux surgery prevents esophageal adenocarcinoma to a larger degree than antireflux medication in patients with Barrett's esophagus. METHODS: This multinational and population-based cohort study included all patients with a diagnosis of Barrett's esophagus in any of the national patient registries in Denmark (2012-2020), Finland (1987-1996 and 2010-2020), Norway (2008-2020), or Sweden (2006-2020). Patients who underwent antireflux surgery were compared with nonoperated patients using antireflux medication. The risk of esophageal adenocarcinoma was calculated using multivariable Cox regression, providing hazard ratios (HRs) and 95% CIs adjusted for age, sex, country, calendar year, and comorbidity. RESULTS: The cohort consisted of 33,939 patients with Barrett's esophagus. Of these, 542 (1.6%) had undergone antireflux surgery. During up to 32 years of follow-up, the overall HR was not decreased in patients having undergone antireflux surgery compared with nonoperated patients using antireflux medication, but rather increased (adjusted HR, 1.9; 95% CI, 1.1-3.5). In addition, HRs did not decrease with longer follow-up, but instead increased for each follow-up category, from 1.8 (95% CI, 0.6-5.0) within 1-4 years of follow-up to 4.4 (95% CI, 1.4-13.5) after 10-32 years of follow-up. CONCLUSIONS: Patients with Barrett's esophagus who undergo antireflux surgery do not seem to have a lower risk of esophageal adenocarcinoma than those using antireflux medication.

OBJECTIVE: Using a comprehensive Australian cohort, we quantified the incidence and determined the independent predictors of intraoperative and postoperative complications associated with antireflux and hiatus hernia surgeries. In addition, we performed an in-depth analysis to understand the complication profiles associated with each independent risk factor. BACKGROUND: Predicting perioperative risks for fundoplication and hiatus hernia repair will inform treatment decision-making, hospital resource allocation, and benchmarking. However, available risk calculators do not account for hernia anatomy or technical aspects of surgery in estimating perioperative risk. METHODS: Retrospective analysis of all elective antireflux and hiatus hernia surgeries in 36 Australian hospitals over 10 years. Hierarchical multivariate logistic regression analyses were performed to determine the independent predictors of intraoperative and postoperative complications accounting for patient, surgical, anatomic, and perioperative factors. RESULTS: A total of 4301 surgeries were analyzed. Of these, 1569 (36.5%) were large/giant hernias and 292 (6.8%) were revisional procedures. The incidence rates of intraoperative and postoperative complications were 12.6% and 13.3%, respectively. The Charlson Comorbidity Index, hernia size, revisional surgery, and baseline anticoagulant usage independently predicted both intraoperative and postoperative complications. These risk factors were associated with their own complication profiles. Finally, using risk matrices, we visualized the cumulative impact of these 4 risk factors on the development of intraoperative, overall postoperative, and major postoperative complications. CONCLUSIONS: This study has improved our understanding of perioperative morbidity associated with antireflux and hiatus hernia surgery. Our findings group patients along a spectrum of perioperative risks that inform care at an individual and institutional level.

PURPOSE OF REVIEW: To compare different therapeutic modalities and determine their role in the treatment of esophageal achalasia. RECENT FINDINGS: The last 3 decades have seen a significant improvement in the diagnosis and treatment of esophageal achalasia. Conventional manometry has been replaced by high-resolution manometry, which has determined a more precise classification of achalasia in three subtypes, with important treatment implications. Therapy, while still palliative, has evolved tremendously. While pneumatic dilatation was for a long time the main choice of treatment, this approach slowly changed at the beginning of the nineties when minimally invasive surgery was adopted, initially thoracoscopically and then laparoscopically with the addition of partial fundoplication. And in 2010, the first report of a new endoscopic technique - peroral endoscopic myotomy (POEM) - was published, revamping the interest in the endoscopic treatment of achalasia. SUMMARY: This review focuses particularly on the comparison of POEM and laparoscopic Heller myotomy (LHM) with partial fundoplication as primary treatment modality for esophageal achalasia. Based on the available data, we believe that LHM with partial fundoplication should be the primary treatment modality in most patients. POEM should be selected when surgical expertise is not available, for type III achalasia, for the treatment of recurrent symptoms, and for patients who had prior abdominal operations that would make LHM challenging and unsafe.

INTRODUCTION: Bronchopulmonary dysplasia (BPD) is a common respiratory morbidity among premature infants. Nissen fundoplication may be performed on infants with BPD to protect the lungs from gastroesophageal reflux-related aspiration, but the indications and benefits associated with fundoplication are not well-defined. This study evaluated associations of Nissen with clinical outcomes in infants with severe BPD (sBPD), using propensity score matching to minimize bias and confounding. METHODS: Infants ≤31 wk gestational age with sBPD (grade 2-3) admitted to a single neonatal intensive care unit (NICU) between January 2016 and October 2021 were included. Patients with sBPD who underwent Nissen fundoplication during initial NICU admission were propensity score-matched at a 1:2 ratio with control patients who did not undergo Nissen (no-Nissen). Outcomes were compared, including time to freedom from respiratory support (defined as ≤2 L nasal cannula), time to initial NICU discharge, and incidence of hospital readmission or death within 1 y postdischarge. RESULTS: After propensity score matching, 18 Nissen infants were compared with 30 no-Nissen infants. The Nissen group trended toward longer time to freedom from respiratory support (median 105 versus 70 d, P = 0.09), and had longer initial hospital stays (188 versus 111 d, P = 0.002), more 1-y hospital readmissions (83% versus 50%, P = 0.04), and more tracheostomies (28% versus 0%, P = 0.005). Mortality during first-year postdischarge was similar (6% versus 10%, P = 1.0). CONCLUSIONS: Despite adjustment for confounding variables, Nissen fundoplication was associated with prolonged support and greater resource utilization among infants with sBPD. Prospective studies are needed to clarify indications for fundoplication in this population.

INTRODUCTION: Achalasia is a rare esophageal disease with potentially lethal complications. Knowledge of the outcomes of the different surgical treatment modalities for achalasia by Heller's cardiomyotomy (HCM) helps to choose the safest and most effective option. However, data on the management of achalsia using a Heller myotomy is limited in Africa. Thus, our aim was to determine the perioperative morbidity, mortality and short-term functional outcomes of HCM in Cameroon. METHODOLOGY: We conducted a cohort study throughout a 10-year chart review of patients who underwent HCM for achalasia and were followed up postoperatively for at least three months at two tertiary health centers in Cameroon. We analyzed demographic data, preoperative clinical and imaging data, treatment details, and outcomes at three to twelve months after HCM using the Eckardt score. RESULTS: We enrolled 29 patients with achalasia having a mean age of 24 ± 16 years and predominantly females (M/F of 1/3.8). The mean symptom duration was 51 ± 20 months. In 80% of cases, the diagnosis was made through a conventional x-ray contrast imaging or "barium swallow test" (93%) and/or an upper gastrointestinal endoscopy (86%). The gold standard diagnostic method via esophageal manometry was unavailable. Preoperatievly, all patients had symptoms suggestive of an active achalasia. HCM was performed via laparotomy in 75% as opposed to 25% laparoscopic HCM procedures. Dor's anterior partial fundoplication was the main anti-reflux procedure performed (59%). Mucosal perforations were the only intraoperative complications in eight patients (2 during laparoscopy vs. 6 during laparotomy; p > 0.5) and were managed successfully by simple sutures. Postoperative complications were non-severe and occurred in 10% of patients all operated via laparotomy. The mean postoperative length of hospital stay was 7 ± 3 days for laparotomy vs. 5 ± 2 days for laparoscopy; p > 0.5. The perioperative mortality rate was nil. Overall, the short-term postoperative functional outcome was rated excellent; average Eckardt score of 1.5 ± 0.5 (vs. preoperative Eckardt Score of 9 ± 1; p < 0.0001). CONCLUSION: Achalasia is diagnosed late in this resource-limited setting. HCM yields satisfactory outcomes, especially via laparoscopic management. An improvement in diagnostic esophageal manometry and mini-invasive surgical infrastructure and the required surgical training/skills are needed for optimal achalasia care.

BACKGROUND: The last 40 years have seen a remarkable change in our understanding of reflux disease. SUMMARY: These changes encompass disease definition and impact, pathophysiology, diagnostic testing, regulatory oversight of clinical trials, pharmacotherapy, endoscopic, and surgical treatment. We have also seen a number of promising therapies fail. KEY MESSAGES: The future holds the promise of further advances. Adaptive artificial intelligence will take over diagnostics in manometry and pH impedance testing and patient-driven outcomes may be changed by interactions with artificial intelligence rather than humans. Changes in chip technology will allow higher resolution chips to be carried on smaller devices making extra-esophageal areas where reflux may play a role more accessible to prolonged observation and testing.

PURPOSE OF REVIEW: Gastroesophageal reflux disease (GERD) is very common in the general population and poses a large societal socio-economic burden. In this article, we review the evidence supporting non-ablative radiofrequency treatment (Stretta) for the endoscopic management of GERD and we compare it to pharmacologic and other minimally invasive and surgical interventions. RECENT FINDINGS: Proton pump inhibitors (PPI) are a key therapy for GERD. For patients without associated significant sliding hiatal hernia, who have inadequate relief of their reflux symptoms, Stretta and other endoscopic therapies, such as transoral fundoplication (TIF), may improve symptoms and GERD-related quality of life. Unfortunately, there are no recent large randomized controlled trials, and most of the evidence is based on meta-analyses and small scale, prospective and retrospective single center efforts. Comparisons of Stretta efficacy to other anti-reflux endoscopic modalities and anti-reflux surgery (ARS) are also presented. There are several endoscopic and minimally invasive modalities to manage PPI-refractory GERD acting through various mechanisms that have been found effective in managing GERD symptoms and quality of life. Among them, Stretta has the longest track record of efficacy and safety. Larger-scale and longer-term comparative efficacy trials in selected populations of patients with acid reflux with and without hiatal hernia will be needed.

INTRODUCTION: Gastroesophageal reflux disease affects a significant portion of the Australian and world population. Minimally invasive laparoscopic fundoplication is a highly effective treatment in appropriately selected patients, with a 90% satisfaction rate. However, up to 5% will undergo revisional surgery. Endoscopy is an important investigation in the evaluation of persistent or new symptoms after fundoplication. Our study sought to evaluate the inter-rater reliability and variability in assessing fundoplication with endoscopy. METHODS: Upper gastrointestinal (UGI) surgeons and gastroenterologists were invited to join the cohort study through their professional membership with two societies based in Australia. Participants completed a two part 25-item multiple choice questionnaire, involving the analysis of ten static endoscopic images post-fundoplication. RESULTS: A total of 101 participants were included in the study (64 UGI surgeons and 37 gastroenterologists). Over 95% of participants were consultant level, working in non-rural tertiary hospitals. Total accuracy for all 10 cases combined was 76% for UGI surgeons and 69.9% for gastroenterologists. In three of the 10 cases, UGI surgeons performed significantly better than gastroenterologists (p < 0.05). When assessing performance across each of the 4 questions for each case, UGI surgeons were more accurate than gastroenterologists in describing the integrity of the wrap (p = 0.014). Inter-rater reliability was low across both groups for most domains (kappa < 1). CONCLUSION: Our study confirms low inter-rater reliability between endoscopists and large variations in reporting. UGI surgeons performed better than gastroenterologists in certain cases, usually when describing the integrity of the fundoplication. Our study provides further support for the use of a standardized reporting system in post-fundoplication patients.

BACKGROUND: The surgical management of hiatal hernia remains controversial. We aimed to compare outcomes of mesh versus no mesh and fundoplication versus no fundoplication in symptomatic patients; surgery versus observation in asymptomatic patients; and redo hernia repair versus conversion to Roux-en-Y reconstruction in recurrent hiatal hernia. METHODS: We searched PubMed, Embase, CINAHL, Cochrane Library and the ClinicalTrials.gov databases between 2000 and 2022 for randomized controlled trials (RCTs), observational studies, and case series (asymptomatic and recurrent hernias). Screening was performed by two trained independent reviewers. Pooled analyses were performed on comparative data. Risk of bias was assessed using the Cochrane Risk of Bias tool and Newcastle Ottawa Scale for randomized and non-randomized studies, respectively. RESULTS: We included 45 studies from 5152 retrieved records. Only six RCTs had low risk of bias. Mesh was associated with a lower recurrence risk (RR = 0.50, 95%CI 0.28, 0.88; I2 = 57%) in observational studies but not RCTs (RR = 0.98, 95%CI 0.47, 2.02; I2 = 34%), and higher total early dysphagia based on five observational studies (RR = 1.44, 95%CI 1.10, 1.89; I2 = 40%) but was not statistically significant in RCTs (RR = 3.00, 95%CI 0.64, 14.16). There was no difference in complications, reintervention, heartburn, reflux, or quality of life. There were no appropriate studies comparing surgery to observation in asymptomatic patients. Fundoplication resulted in higher early dysphagia in both observational studies and RCTs ([RR = 2.08, 95%CI 1.16, 3.76] and [RR = 20.58, 95%CI 1.34, 316.69]) but lower reflux in RCTs (RR = 0.31, 95%CI 0.17, 0.56, I2 = 0%). Conversion to Roux-en-Y was associated with a lower reintervention risk after 30 days compared to redo surgery. CONCLUSIONS: The evidence for optimal management of symptomatic and recurrent hiatal hernia remains controversial, underpinned by studies with a high risk of bias. Shared decision making between surgeon and patient is essential for optimal outcomes.

BACKGROUND: Laparoscopic hiatal hernia repair (LHHR) is a complex operation requiring advanced surgical training. Surgical simulation offers a potential solution for learning complex operations without the need for high surgical volume. Our goal is to develop a virtual reality (VR) simulator for LHHR; however, data supporting task-specific metrics for this procedure are lacking. The purpose of this study was to develop and assess validity and reliability evidence of task-specific metrics for the fundoplication phase of LHHR. METHODS: In phase I, structured interviews with expert foregut surgeons were conducted to develop task-specific metrics (TSM). In phase II, participants with varying levels of surgical expertise performed a laparoscopic Nissen fundoplication procedure on a porcine stomach explant. Video recordings were independently assessed by two blinded graders using global and TSM. An intraclass correlation coefficient (ICC) was used to assess interrater reliability (IRR). Performance scores were compared using a Kruskal-Wallis test. Spearman's rank correlation was used to evaluate the association between global and TSM. RESULTS: Phase I of the study consisted of 12 interviews with expert foregut surgeons. Phase II engaged 31 surgery residents, a fellow, and 6 attendings in the simulation. Phase II results showed high IRR for both global (ICC = 0.84, p < 0.001) and TSM (ICC = 0.75, p < 0.001). Significant between-group differences were detected for both global (χ2 = 24.01, p < 0.001) and TSM (χ2 = 18.4, p < 0.001). Post hoc analysis showed significant differences in performance between the three groups for both metrics (p < 0.05). There was a strong positive correlation between the global and TSM (rs = 0.86, p < 0.001). CONCLUSION: We developed task-specific metrics for LHHR and using a fundoplication model, we documented significant reliability and validity evidence. We anticipate that these LHHR task-specific metrics will be useful in our planned VR simulator.

PURPOSE: Magnetic Sphincter Augmentation (MSA) is an FDA-approved anti-reflux procedure with comparable outcomes to fundoplication. However, most data regarding its use are limited to single or small multicenter studies which may limit the generalizability of its efficacy. The purpose of this study is to evaluate the outcomes of patients undergoing MSA vs fundoplication in a national database. MATERIALS AND METHODS: The 2017-2020 American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) Registry was utilized to evaluate patients undergoing MSA or fundoplication. Patients requiring Collis gastroplasty, paraesophageal hernia repair, and emergency cases, were excluded. Patient outcomes included overall complication rates, readmissions, reoperations, and mortality. RESULTS: A total of 7,882 patients underwent MSA (n = 597) or fundoplication (n = 7285). MSA patients were younger (51 vs 57, p < 0.001), and more often male (49.6 vs 34.3%, p < 0.001). While patients undergoing MSA experienced similar rates of reoperation (1.0 vs 2.0%, p = 0.095), they experienced fewer readmissions (2.2 vs 4.7%, p = 0.005), complications (0.6 vs 4.0%, p < 0.001), shorter mean (SD) hospital length of stay(days) (0.4 ± 4.3 vs 1.8 ± 4.6, p < 0.001) and operative time(min) (80.8 ± 36.1 vs 118.7 ± 63.7, p < 0.001). Mortality was similar between groups (0 vs 0.3%, p = 0.175). On multivariable analysis, MSA was independently associated with reduced postoperative complications (OR 0.23, CI 0.08 to 0.61, p = 0.002), readmissions (OR 0.53, CI 0.30 to 0.94, p = 0.02), operative time (RC - 36.56, CI - 41.62 to - 31.49. p < 0.001) and length of stay (RC - 1.22, CI - 1.61 to - 0.84 p < 0.001). CONCLUSION: In this national database study, compared to fundoplication MSA was associated with reduced postoperative complications, fewer readmissions, and shorter operative time and hospital length of stay. While randomized trials are lacking between MSA and fundoplication, both institutional and national database studies continue to support the use of MSA as a safe anti-reflux operation.

BACKGROUND: The Acquisition of Data for Outcomes and Procedure Transfer (ADOPT) program was established by SAGES to develop and expand individual surgeon's comfort with specific, complex operations using hands-on teaching and longitudinal mentoring. The 2022-2023 Foregut (Dominating the Hiatus) section of the course focused on hiatal hernia dissection and gastric fundoplication techniques. Our aim was to describe the experience of surgeons who participated in the course. METHODS: The hands-on component occurred in March 2022 at the SAGES annual meeting. Each expert mentor was matched to two participants. The mentors guided the surgeons through steps of a laparoscopic paraesophageal (PEH) hernia repair and fundoplication using a cadaveric model. Afterwards, monthly group webinars occurred and participants could receive individual coaching from their assigned mentor for a year. Each participant was given a pre-course survey with 3 and 12-month follow-up questionnaires. RESULTS: The majority of the 16 participants were employed in non-academic settings (87.5%). Years in practice ranged from 1 to 26, and 69% completed a fellowship. 100% completed the pre-course survey, and 53.8% responded to the 12-month post-course survey. Participant-reported effectiveness in performing a PEH hernia repair with fundoplication increased from 37.5% pre-course to 85.7% by the conclusion of the course. Confidence levels for the six core steps of the operation also increased: pre-course only 56-75% were confident with each step, this improved to 100% in four out of six steps. 85.7% said the course has changed their practice. DISCUSSION: Since inception, the ADOPT program has aimed to provide expert instruction for practicing surgeons to learn new techniques or improve their confidence in performing operations. The data for the 2022 ADOPT Foregut course shows that 1 year of participation made a positive impact on these surgeons' practices. This helps to fill in the learning gap that occurs after formal surgical training ends.

INTRODUCTION: The introduction of the functional lumen imaging probe (FLIP) has provided objective, real-time feedback on the geometric variations with each component of a hiatal hernia repair (HHR). The utility of this technology in altering intraoperative decision-making has been scarcely reported. Herein, we report a single-center series of intraoperative FLIP during HHR. METHODS: A retrospective review of electronic medical records between 2020 and 2022 was conducted and all patients undergoing non-recurrent HHR with FLIP were queried. Patient and hernia characteristics, intraoperative FLIP values and changes in decision-making, as well as early post-operative outcomes were reported. Both diameter and distensibility index (DI) were measured at 40 ml and 50 ml balloon inflation after hiatal dissection, after hiatal closure, and after fundoplication when indicated. RESULTS: Thirty-three patients met inclusion criteria. Mean age was 62 ± 14 years and mean BMI was 28 ± 6 kg/m2. The majority (53%) were type I hiatal hernias. The largest drop in DI occurred after hiatal closure, with minimal change seen after fundoplication (mean DI of 4.3 ± 2. after completion of HH dissection, vs 2.7 ± 1.2 after hiatal closure and 2.3 ± 1 after fundoplication when performed). In 13 (39%) of cases, FLIP values directly impacted intraoperative decision-making. Fundoplication was deferred in 4/13 (31%) patients, the wrap was loosened in 2/13 (15%); the type of fundoplication was altered to achieve adequate anti-reflux values in 2/13 (15%) patients, and in 1/13 (3%) the wrap was tightened. CONCLUSION: FLIP measurements can be used intraoperatively to guide decision-making and alter management plan based on objective values. Long-term outcomes and further prospective studies are required to better delineate the value of this technology.

BACKGROUND: The increasing use of robotic systems for anti-reflux operations prompted this study to evaluate and compare the efficacy of robotic and Laparo-Endoscopic Single-Site (LESS) approaches. METHODS: From 2012, 228 robotic fundoplication and 518 LESS fundoplication patients were prospectively followed, analyzing perioperative metrics. Data are presented as median (mean ± SD); significance at p ≤ 0.05. RESULTS: Patients undergoing a robotic vs. LESS fundoplication were 67 (64 ± 13.7) vs. 61 (59 ± 15.1) years-old with BMIs of 25 (25 ± 3.2) vs. 26 (25 ± 3.9) kg/m2 (p = 0.001 and 1.00, respectively). 72% of patients who underwent the robotic approach had a previous abdominal operation(s) vs 44% who underwent the LESS approach (p = 0.0001). 38% vs. 8% had a re-operative fundoplication (p = 0.0001), 59% vs. 45% had a type IV hiatal hernia (p = 0.0004). Operative duration was 160 (176 ± 76.7) vs. 130 (135 ± 50.5) min (p = 0.0001). There were 0 (robotic) vs. 5 (LESS) conversions to a different approach (p = 0.33). 5 Patients vs. 3 patients experienced postoperative complications (p = 0.06), and length of stay (LOS) was 1 (2 ± 2.6) vs. 1 (1 ± 3.2) days (p = 0.0001). Patient symptomatic dysphagia preoperatively for the robotic vs. LESS approach was scored as 2 (2.4 ± 1.9) vs. 1 (1.9 ± 1.6). Postoperatively, symptomatic dysphagia was scored as 1 (1.5 ± 1.6) vs. 1 (1.7 ± 1.7). The change in these scores was - 1 (- 1 ± 2.2) vs. 0 (- 0.5 ± 2.2) (p = 0.004). CONCLUSION: Despite longer operative times and LOS in older patients, the robotic approach is efficient in undertaking very difficult operations, including patients with type IV or recurrent hiatal hernias. Furthermore, preoperative anti-reflux operations were more likely to be undertaken with the robotic approach than the LESS approach. The patient's postoperative symptomatic dysphagia improved relatively more than after the LESS approach. The vast majority of patients who underwent the LESS approach enjoyed improved cosmesis, thus, making LESS a stronger candidate for more routine operations. Despite patient selection bias, the robotic and LESS approaches to anti-reflux operations are safe, efficacious, and should be situationally utilized.

BACKGROUND: Anti-reflux operations are effective treatments for GERD. Despite standardized surgical techniques, variability in post-operative outcomes persists. Most patients with GERD possess one or more characteristics that augment their disease and may affect post-operative outcomes-a GERD "phenotype". We sought to define these phenotypes and to compare their post-operative outcomes. METHODS: We performed a retrospective review of a prospective gastroesophageal database at our institution, selecting all patients who underwent an anti-reflux procedure for GERD. Patients were grouped into different phenotypes based on the presence of four characteristics known to play a role in GERD: hiatal or paraesophageal hernia (PEH), hypotensive LES, esophageal dysmotility, delayed gastric emptying (DGE), and obesity. Patient-reported outcomes (GERD-HRQL, dysphagia, and reflux symptom index (RSI) scores) were compared across phenotypes using the Wilcoxon rank-sum test. RESULTS: 690 patients underwent an anti-reflux procedure between 2008 and 2022. Most patients underwent a Nissen fundoplication (302, 54%), followed by a Toupet or Dor fundoplication (205, 37%). Twelve distinct phenotypes emerged. Non-obese patients with normal esophageal motility, normotensive LES, no DGE, with a PEH represented the most common phenotype (134, 24%). The phenotype with the best post-operative GERD-HRQL scores at one year was defined by obesity, hypotensive LES, and PEH, while the phenotype with the worst scores was defined by obesity, ineffective motility, and PEH (1.5 ± 2.4 vs 9.8 ± 11.4, p = 0.010). There was no statistically significant difference in GERD-HRQL, dysphagia, or RSI scores between phenotypes after five years. CONCLUSIONS: We have identified distinct phenotypes based on common GERD-associated patient characteristics. With further study these phenotypes may aid surgeons in prognosticating outcomes to individual patients considering an anti-reflux procedure.

BACKGROUND: Paraesophageal hernia repairs (PEHRs) have high rates of radiographic recurrence, with some patients requiring repeat operation. This study characterizes patients who underwent PEHR to identify the factors associated with postoperative symptom improvement and radiographic recurrence. We furthermore use propensity score matching to compare patients undergoing initial and reoperative PEHR to identify the factors predictive of recurrence or need for reoperation. METHODS: After IRB approval, patients who underwent PEHR at a tertiary care center between January 2018 and December 2022 were identified. Patient characteristics, preoperative imaging, operative findings, and postoperative outcomes were recorded. A computational generalization of inverse propensity score weight was then used to construct populations of initial and redo PEHR patients with similar covariate distributions. RESULTS: A total of 244 patients underwent PEHR (78.7% female, mean age 65.4 ± 12.3 years). Most repairs were performed with crural closure (81.4%) and fundoplication (71.7%) with 14.2% utilizing mesh. Postoperatively, 76.5% of patients had subjective symptom improvement and of 157 patients with postoperative imaging, 52.9% had evidence of radiographic recurrence at a mean follow-up of 10.4 ± 13.6 months. Only 4.9% of patients required a redo operation. Hernia type, crural closure, fundoplication, and mesh usage were not predictors of radiographic recurrence or symptom improvement (P > 0.05). Propensity weight score analysis of 50 redo PEHRs compared to a matched cohort of 194 initial operations revealed lower rates of postoperative symptom improvement (P < 0.05) but no differences in need for revision, complication rates, ED visits, or readmissions. CONCLUSIONS: Most PEHR patients have symptomatic improvement with minimal complications and reoperations despite frequent radiographic recurrence. Hernia type, crural closure, fundoplication, and mesh usage were not significantly associated with recurrence or symptom improvement. Compared to initial PEHR, reoperative PEHRs had lower rates of symptom improvement but similar rates of recurrence, complications, and need for reoperation.

BACKGROUND: Hiatal Hernia (HH) is a common structural defect of the diaphragm. Laparoscopic repair with suturing of the hiatal pillars followed by fundoplication has become standard practice. In an attempt to lower HH recurrence rates, mesh reinforcement, commonly located at the posterior site of the esophageal hiatus, has been used. However, effectiveness of posterior mesh augmentation is still up to debate. There is a lack of understanding of the mechanism of recurrence requiring further investigation. We investigated the anatomic location of HH recurrences in an attempt to assess why HH recurrence rates remain high despite various attempts with mesh reinforcement. METHODS: A retrospective case series of prospectively collected data from patients with hiatal hernia repair between 2012 and 2020 was performed. In total, 54 patients with a recurrent hiatal hernia operation were included in the study. Video clips from the revision procedure were analyzed by a surgical registrar and senior surgeon to assess the anatomic location of recurrent HH. For the assessment, the esophageal hiatus was divided into four equal quadrants. Additionally, patient demographics, hiatal hernia characteristics, and operation details were collected and analyzed. RESULTS: 54 patients were included. The median time between primary repair and revision procedure was 25 months (IQR 13-95, range 0-250). The left-anterior quadrant was involved in 43 patients (80%), the right-anterior quadrant in 21 patients (39%), the left-posterior quadrant in 21 patients (39%), and the right-posterior quadrant in 10 patients (19%). CONCLUSION: In this study, hiatal hernia recurrences occured most commonly at the left-anterior quadrant of the hiatus, however, posterior recurrences were not uncommon. Based on our results, we hypothesize that both posterior and anterior hiatal reinforcement might be a suitable solution to lower the recurrence rate of hiatal hernia. A randomized controlled trial using a circular, bio-absorbable mesh has been initiated to test our hypothesis.

INTRODUCTION: Endoluminal functional lumen imaging probe (EndoFLIP) provides a real-time assessment of gastroesophageal junction (GEJ) compliance during fundoplication. Given the limited data on EndoFLIP measurements during the Hill procedure, we investigated the impact of the Hill procedure on GEJ compliance compared to Toupet fundoplication. METHODS: Patients who underwent robotic Hill or Toupet fundoplication with intraoperative EndoFLIP between 2017 and 2022 were included. EndoFLIP measurements of the GEJ included cross sectional surface area (CSA), intra-balloon pressure, high pressure zone length (HPZ), distensibility index (DI), and compliance. Subjective reflux symptoms, gastroesophageal reflux disease-health related quality of life (GERD-HRQL) score, and dysphagia score were assessed pre-operatively as well as at short- and longer-term follow-up. RESULTS: One-hundred and fifty-four patients (71.9%) had a Toupet fundoplication while sixty (28%) patients underwent the Hill procedure. The CSA [27.7 ± 10.9 mm2 vs 42.2 ± 17.8 mm2, p < 0.0001], pressure [29.5 ± 6.2 mmHg vs 33.9 ± 8.5 mmHg, p = 0.0009], DI [0.9 ± 0.4 mm2/mmHg vs 1.3 ± 0.6 mm2/mmHg, p = 0.001], and compliance [25.9 ± 12.8 mm3/mmHg vs 35.4 ± 13.4 mm3/mmHg, p = 0.01] were lower after the Hill procedure compared to Toupet. However, there was no difference in post-fundoplication HPZ between procedures [Hill: 2.9 ± 0.4 cm, Toupet: 3.1 ± 0.6 cm, p = 0.15]. Follow-up showed no significant differences in GERD-HRQL scores, overall dysphagia scores or atypical symptoms between groups (p > 0.05). CONCLUSION: The Hill procedure is as effective to the Toupet fundoplication in surgically treating gastroesophageal reflux disease (GERD) despite the lower CSA, DI, and compliance after the Hill procedure. Both procedures led to DI < 2 mm2/mmHg with no significant differences in dysphagia reporting (12-24) months after the procedure. Further studies to elucidate a cutoff value for DI for postoperative dysphagia development are still warranted.

INTRODUCTION: With the advent of the laparoscopic era in the 1990s, laparoscopic Heller myotomy replaced pneumatic dilation as the first-line treatment for achalasia. An advantage of this approach was the addition of a fundoplication to reduce gastroesophageal reflux disease (GERD). More recently, Peroral Endoscopic Myotomy has competed for first-line therapy, but the postoperative GERD may be a weakness. This study leverages our experience to characterize GERD following LHM with Toupet fundoplication (LHM+T ) so that other treatments can be appropriately compared. METHODS: A single-institution retrospective review of adult patients with achalasia who underwent LHM+T from January 2012 to April 2022 was performed. We obtained routine 6-month postoperative pH studies and patient symptom questionnaires. Differences in questionnaires and reflux symptoms in relation to pH study were explored via Kruskal-Wallis test or chi-square tests. RESULTS: Of 170 patients who underwent LHM+T , 51 (30%) had postoperative pH testing and clinical symptoms evaluation. Eleven (22%) had an abnormal pH study; however, upon manual review, 5 of these (45.5%) demonstrated low-frequency, long-duration reflux events, suggesting poor esophageal clearance of gastric refluxate and 6/11 (54.5%) had typical reflux episodes. Of the cohort, 7 (15.6%) patients reported GERD symptoms. The median [IQR] severity was 1/10 [0, 3] and median [IQR] frequency was 0.5/4 [0, 1]. Patients with abnormal pH reported more GERD symptoms than patients with a normal pH study (3/6, 50% vs 5/39, 12.8%, p = 0.033). Those with a poor esophageal clearance pattern (n = 5) reported no concurrent GERD symptoms. CONCLUSION: The incidence of GERD burden after LHM+T is relatively low; however, the nuances relevant to accurate diagnosis in treated achalasia patients must be considered. Symptom correlation to abnormal pH study is unreliable making objective postoperative testing important. Furthermore, manual review of abnormal pH studies is necessary to distinguish GERD from poor esophageal clearance.

INTRODUCTION: A history of lung transplantation is a risk factor for poor outcomes in patients undergoing laparoscopic fundoplication. We wanted to determine whether enhanced recovery after a robotic-assisted surgery program would mitigate these risks. METHODS: We performed a single-center retrospective analysis of the Society of Thoracic Surgery database for patients who underwent elective antireflux procedures from 1/2018 to 2/2021 under the enhanced recovery after surgery program using robotic assistance. We identified the patient and surgical characteristics, morbidity, length of stay, and 30-day readmission rates. RESULTS: Among 386 patients who underwent barrier creation, 41 had previously undergone a lung transplant, either bilateral (n = 28) or single (n = 13). There were no significant differences in postoperative complications (9.8% vs. 5.2%, p = 0.27), median hospital length of stay (1 d vs. 1 d, p = 0.28), or 30-day readmission (7.3% vs. 4.9%, p = 0.46). Bivariate analysis showed that older age (p = 0.03), history of DVT/PE (p < 0.001), history of cerebrovascular events (p = 0.03), opioid dependence (p = 0.02), neurocognitive dysfunction (p < 0.001), and dependent functional status (p = 0.02) were associated with postoperative complications. However, lung transplantation was not associated with an increased risk of postoperative complications (p = 0.28). DISCUSSION: The risk of surgical complications in patients with a history of lung transplantation may be mitigated by the combination of ERAS and minimally invasive surgery such as robot-assisted surgery.
