Finding relief for the self-conscious esophagus: laparoscopic anti-reflux surgery and the esophageal hypersensitivity and anxiety scale.

INTRODUCTION: Measures of mood and effective coping strategies have notable correlations with quality of life and treatment responses. There is evidence that patients with previously diagnosed anxiety disorders have less improvement in patient-reported outcome measures (PROMs) after laparoscopic anti-reflux surgery (LARS) and that objective pathology does not correlate well with symptom severity. We were interested in investigating whether anxiety and hypervigilance, as measured preoperatively with the esophageal hypervigilance anxiety scale (EHAS), is associated with the improvement in GERD-specific PROMs and EHAS scores 6 months after LARS. METHODS: We performed a retrospective cohort study of 102 adult patients (31% men, average age 64) who underwent LARS. In the preoperative evaluation, baseline gastroesophageal reflux disease-health-related quality of life (GERD-HRQL), laryngopharyngeal reflux symptom index (LPR-RSI) and EHAS scores were collected in addition to the standard reflux workup, including endoscopy, manometry, barium swallow, and pH study. For all three surveys, a higher score represents worse symptom severity. At 6 months postoperatively, 70 patients completed repeat GERD-HRQL, LPR-RSI, and EHAS surveys. We then analyzed for surgical and patient-related factors associated with improvement in the 6-month postoperative GERD-HRQL and LPR-RSI scores. RESULTS: There was a statistically significant decrease in the GERD-HRQL (25 vs. 2, p < 0.001), LPR-RSI (17 vs. 3, p < 0.001) and EHAS (34 vs. 15, p < 0.001) 6 months after LARS. On multivariable linear regression, a higher baseline EHAS score was independently associated with a greater improvement in GERD-HRQL (ß 0.35, p < 0.001) and LPR-RSI (ß 0.19, p = 0.03) 6-months after LARS. Additionally, the degree of improvement in EHAS, GERD-HRQL, and LPR-RSI was not influenced by the type of LARS performed or by the severity of disease. CONCLUSION: These findings are consistent with literature suggesting that measures of psychoemotional health correlate better with symptom intensity than objective pathology. We found that patients with a higher EHAS score have greater symptom severity and lower quality of life at baseline. Novel findings to this study are that patients with a higher preoperative EHAS, a measure of psychoemotional health, actually benefitted more from surgery and not less, which has been the traditional view in the literature. Future studies are warranted to establish directionality and explore the role of preoperative cognitive behavioral therapy with LARS for patients with significant symptoms of hypervigilance and anxiety.

Psychoemotional factors and their influence on the quality of life in patients with GERD.

Patient-reported outcomes (PROs) are integral to determining the success of foregut surgical interventions and psychoemotional factors have been hypothesized to impact the quality of life of patients. This study evaluates the correlation between PROs-specifically the Gastroesophageal Reflux Disease-Health-Related Quality of Life (GERD-HRQL) and the Laryngopharangeal Reflux Symptom Index (LPR-RSI)-and the recently validated Esophageal Hypervigilance Anxiety Scale (EHAS). We hypothesize that patients with higher EHAS scores have significantly elevated GERD-HRQL LPR-RSI compared to those with normal scores. EHAS has been developed and validated in chronic esophageal disorders, but clinical impact is unknown. In this retrospective study, 197 patients (38% men, average age 56 ± 16) completed the following surveys:(1) EHAS, (2) GERD-HRQL, and (3) LPR-RSI. All patients referred for surgical evaluation of GERD completed the surveys as part of their pre-operative workup and post-operative follow-up In bivariate analysis, EHAS correlated with both GERD-HRQL (r 0.53, P = <0.001) and LPR-RSI (r 0.36, P = 0.009). Accounting for potential confounding with sex and age in multivariable linear regression models, a higher GERD-HRQL score (ß 0.38; 95% CI 0.29 to 0.48; P = <0.001; Semipartial R2 0.20) and a higher LPR-RSI score (ß 0.21; 95% CI 0.13 to 0.29; P = <0.001; Semipartial R2 0.08) were independently associated with higher EHAS. The observed relationship between mental health and GERD symptom intensity is consistent with the biopsychosocial paradigm of illness. Future studies focused on post-surgical outcomes following the incorporation of EHAS into perioperative care is needed to evaluate its effectiveness as a clinical decision support tool in ARS.

Favorable results from a prospective evaluation of 200 patients with large hiatal hernias undergoing LINX magnetic sphincter augmentation.

INTRODUCTION: Magnetic sphincter augmentation (MSA) of the lower esophageal sphincter restores the antireflux barrier in patients with hiatal hernias ≤3 cm. We performed a prospective study in patients undergoing MSA with the LINX device during repair of paraesophageal and hernias over 3 cm axial component. METHODS AND PROCEDURES: Multicenter, prospective study of consecutive patients treated with MSA at the time of repair of hiatal hernias >3 cm. RESULTS: 200 patients (110 female) were treated between March 2014 and February 2017 via laparoscopic hernia repair and MSA. Mean age was 59.5 years, mean BMI 29.4. 40% had esophagitis, 20% intestinal metaplasia, 72 of 77 tested had abnormal pH studies. Preoperative PPI use was reported by 87%. Eighteen patients had prior hiatal hernia/fundoplication. All had normal function. 78% of patients had axial hiatal hernia ≥5 cm or large paraesophageal component. Mean operative time was 81 min (38-193), EBL was 10 cc. Non-permanent mesh reinforcement of hiatal repair was performed in 83% of the patients. There were two readmissions for dehydration; 2 patients with pulmonary embolism, and 1 patient with cardiac ischemia. Nineteen patients required dilation. 156 pts were followed at a median of 8.6 months. GERD-HRQL scores improved from 26 preoperatively to 2 postoperatively. Complete PPI independence was achieved in 94% (147/156). Videoesophagram in 51 patients at median 11 months found 3 asymptomatic hernias <3 cm. One symptomatic patient underwent successful repair of the hernia without MSA manipulation. There have been no device explants, erosions, or migrations to date. CONCLUSIONS: This prospective study of 200 patients with >3 cm hernias undergoing MSA with hiatoplasty resulted in favorable outcomes with median of 9 months follow-up. Comparing this to published reports of MSA in patients with <3 cm hernias, the safety and clinical efficacy of MSA are independent of initial hernia size.

Outcomes of magnetic sphincter augmentation - A community hospital perspective.

BACKGROUND: Magnetic sphincter augmentation (MSA) is FDA approved for the surgical treatment of GERD. While multiple reports from academic settings exist, we report the early experience from two community-based health systems. METHODS: The first 102 post-trial cases of MSA were reviewed. Outcomes were compared to those in the initial clinical trial. RESULTS: Mean follow-up duration was 7.6 months. GERD medication use decreased from 98% preoperative to 8% postoperative (P<0.001). Median GERD health-related quality of life (HRQL) improved from 27 preoperative to 5 postoperative (P<0.001). Patient satisfaction increased from 8% preoperative to 84% postoperative (P<0.001). Results were similar to the trial data. CONCLUSIONS: MSA is a safe and effective treatment for GERD, with significant improvement in quality of life. GERD-HRQL, medication reduction, operative times, and dysphagia rates were similar to other reports, demonstrating the reproducibility of MSA. Lower dilation rates may be due to refinements in technique and postoperative dietary management.
