Current Status of Anti-Reflux Surgery as a Treatment for GERD

Clinical outcomes of endoscopic balloon dilation for dysphagia after anti-gastroesophageal reflux surgery

BACKGROUND

Dysphagia is a potential complication following anti-gastroesophageal reflux surgery (ARS), with challenging management. Endoscopic balloon dilation is recommended for patients with significant dysphagia from tight wraps or strictures. We aim to evaluate factors associated with the need for post-ARS dilation and the outcomes of balloon dilation. Additionally, we assessed the predictors of sustained clinical failure after dilation.

METHODS

A retrospective analysis was conducted on patients who underwent robotic or laparoscopic ARS between January 2012 and April 2023. Patients were divided based on whether they received balloon dilation using a through-the-scope wire-guided dilator. Excluded were those with pre-existing achalasia, other dilation devices, or inadequate follow-up.

RESULTS

Of 1002 patients, 69 underwent 94 postoperative dilations, and the remainder were controls. The dilation cohort was older (63.78 vs. 56.14 years, P = 0.032) and had more magnetic sphincter augmentations (MSA) (P = 0.004), a prior history of ARS (P = 0.039), and a higher rate of laparoscopic surgery (P = 0.009) compared to controls. Of all dilations, 54 (57.5%) patients reported immediate dysphagia improvement, and 39 (41.5%) had sustained improvement. Sixteen (23.2%) patients required reoperation, primarily for hiatal hernia recurrence or slipped wrap. Multivariable logistic regression showed that MSA (OR 0.04, 95% CI 0.01-0.46, P = 0.031) and requiring multiple dilations (OR 0.16, CI 0.03-0.68) predicted sustained dilation failure.

CONCLUSIONS

Factors including older age, history of prior ARS, and MSA are correlated with higher post-ARS dilation rates. Although dilation improves symptoms in approximately half of patients initially, one-fourth may eventually require reoperation, mostly due to a slipped wrap or hernia recurrence. Thus, in cases of persistent dysphagia, consideration for surgical failure is important, and further imaging and workup are warranted. Patients who undergo MSA and those who have more than one dilation are more likely to experience dilation failure.

Impact of Age on Long-Term Outcomes of Laparoscopic Nissen Fundoplication-A Single Center Study

Background and objectives: Gastroesophageal reflux disease (GERD) is a common disease affecting approximately 20% of the adult population. This study aimed to compare the results of laparoscopic Nissen fundoplication (LNF) in the treatment of GERD in patients of different age groups. Materials and Methods: A retrospective analysis was performed on patients who underwent LNF in one surgical department between 2014 and 2018. Patients were divided into three groups based on age: under 40 years of age, 40-65 years of age, and over 65 years of age. Results: A total of 111 patients (44.1% women) were analyzed in this study. The mean age was 50.2 ±15 years, and the mean follow-up was 50 months ± 16.6 months. Recurrence of symptoms occurred in 23%, 20%, and 23% in each age group, respectively (p = 0.13), and 85%, 89%, and 80% of patients from the respective groups reported that they would recommend the surgery to their relatives (p = 0.66). Furthermore, 83%, 92%, and 73% of patients from the respective age groups reported that they would undergo the surgery again with the knowledge they now had (p = 0.16). Conclusions: Given these results and observations, LNF has been shown to be a good method of treatment for GERD in every age group. In our study, there were no differences found in terms of satisfaction with surgery and associated recommendations between the studied age groups.
