Zhu, Zeng, Yang, Cheng, and Zhou: Letter to the editor on “Bariatric surgery reduces long-term mortality in patients with metabolic dysfunction-associated steatotic liver disease and cirrhosis”
Dear Editor,
We read with great interest the population-based study by Rouillard et al. [1], which highlights the significant reduction in long-term mortality among patients with metabolic dysfunction-associated steatotic liver disease (MASLD) and cirrhosis who underwent bariatric surgery. The study’s findings—particularly the 37% reduction in overall mortality and 76% reduction in liver-related mortality with laparoscopic approaches—offer valuable insights into managing this high-risk population [1]. However, we wish to contextualize these results through multidisciplinary lenses to inform clinical practice, public health policies, and healthcare economics.
The study underscores the safety and efficacy of laparoscopic bariatric surgery in cirrhotic patients, a population historically deemed high-risk for surgical interventions. While the data are compelling, the exclusion of patients with advanced decompensation (e.g., refractory ascites, hepatic encephalopathy) limits generalizability to all cirrhosis stages. Future studies should stratify outcomes by Child-Pugh or MELD scores to guide patient selection. Additionally, the elevated non-liver cancer mortality in the surgical group (14.2% vs. 10.8% at 10 years) warrants exploration— whether this reflects surveillance bias, metabolic changes post-surgery, or residual confounding.
MASLD disproportionately affects marginalized communities due to socioeconomic barriers to healthy diets and exercise. Bariatric surgery could mitigate health disparities if accessible to these groups. However, the study cohort’s racial/ethnic composition (55.9% non-Hispanic White) and insurance profiles (46.9% private/HMO) suggest potential inequities in surgical access. Public health initiatives must address systemic barriers (e.g., insurance coverage, provider bias) to ensure equitable delivery of evidence-based interventions. Furthermore, societal stigma around obesity may deter eligible patients from pursuing surgery; culturally sensitive education campaigns are needed to destigmatize surgical options.
The study covers the period from 2005 to 2019, during which there have been significant advancements in weight loss surgery techniques. Currently, laparoscopic sleeve gastrectomy and certain endoscopic procedures (such as endoscopic sleeve gastroplasty) have gradually replaced traditional open surgeries and gastric banding due to their enhanced safety [2]. However, in the analysis, all laparoscopic surgeries were grouped together without distinguishing the outcomes of different surgical methods. For example, while gastric banding surgery showed the greatest reduction in mortality (with a hazard ratio of 0.23) in the study, it is now rarely performed due to its numerous long-term complications. This is similar to the study’s mention of favorable results that were primarily driven by a now-obsolete surgical approach. Therefore, the relevance of these findings to current surgical practices is limited.
Future directions:
1. Mechanistic Studies: Explore how weight loss modulates gut-liver axis dynamics and fibrosis regression in cirrhosis.
2. Policy Advocacy: Partner with payers to expand coverage for bariatric surgery in cirrhotic patients, particularly in underserved regions.
3. Technological Integration: Investigate hybrid approaches combining laparoscopic surgery with emerging therapies (e.g., FXR agonists) to optimize outcomes.
In conclusion, this study provides robust evidence supporting bariatric surgery as a lifesaving intervention for MASLD-related cirrhosis. By addressing clinical, social, and economic dimensions, we can translate these findings into actionable strategies that improve survival and quality of life for this growing patient population.
