Bariatric surgery in patients with interstitial lung disease

Area of Science:

• Pulmonology
• Bariatric Surgery
• Interventional Cardiology

Background:

• Perioperative pulmonary complications are common in patients with interstitial lung diseases (ILD).
• Limited data exists on the safety of bariatric procedures for ILD patients.
• This study evaluates bariatric surgery outcomes in ILD patients.

Purpose of the Study:

• To assess the safety and feasibility of bariatric surgery in patients with ILD.
• To evaluate the short-term and long-term outcomes of bariatric surgery in this population.
• To determine the impact of weight loss on pulmonary function and lung transplant candidacy.

Main Methods:

• Retrospective review of 25 ILD patients who underwent bariatric surgery (2004-2014).
• Surgical procedures included Roux-en-Y gastric bypass, sleeve gastrectomy, and adjustable gastric banding.
• Data collected included demographics, operative details, complications, weight loss, pulmonary function tests (PFTs), and transplant status.

Main Results:

• Bariatric surgery was performed on 25 ILD patients (68% female, median age 53, median BMI 39 kg/m²).
• 16% experienced 30-day complications, with no pulmonary complications or ICU admissions.
• One-year follow-up showed significant weight loss (median 67% excess weight loss) and improved PFTs (FVC and DLCO).
• Six of seven potential lung transplant candidates became eligible post-surgery; one underwent successful transplant.

Conclusions:

• Bariatric surgery in ILD patients is relatively safe with acceptable perioperative morbidity.
• Significant weight loss and pulmonary function improvements were observed.
• Bariatric surgery can improve lung transplant candidacy for selected ILD patients.
