Major respiratory adverse events after laparascopic gastric banding surgery for morbid obesity.

Abstract：

BACKGROUND:Laparoscopic adjustable gastric banding surgery has become one of the most common restrictive surgical procedures for treatment of morbid obesity worldwide. Although short-term respiratory complications are well known, long-term data is scarce. We investigated the manifestations of major pulmonary complications showed at least six months after the procedure. METHODS:A retrospective cohort study was conducted at a tertiary university medical center in the five years period of 2006-2010. We included every patient who had had major respiratory complication who needed hospitalization, at least 6 months after laparoscopic adjustable gastric banding procedure. Demographic, pre-operative and post-operative clinical data were collected. We documented respiratory symptoms, results of physical examination, pulmonary function tests, and imaging as well as therapies given and outcome. RESULTS:Out of 2100 patients who underwent LAGB, thirty subjects, mean age of 45.7 (range 29-64) with an equal number of males and females were included. Mean interval between operation and onset of respiratory symptoms was 51.5 months (range 10-150 months). All had dyspeptic complaints which included: regurgitation, fullness after meals, dysphagia and food aspiration with esophageal dilatation. Major respiratory complications included aspiration pneumonia (19) including pulmonary abscess (4) and empyema (2), exacerbation of asthma (3) and hemoptysis (1). Additionally we documented the emergence of chronic diseases such as interstitial lung disease (5) and bronchiectasis (3). One patient developed acute respiratory distress syndrome due to aspiration pneumonia and eventually died in the intensive care unit. The main mode of therapy was deflation of the gastric band. Those who refused to deflate or remove the gastric banding continued to suffer from dyspeptic and respiratory symptoms including recurrent pulmonary abscess. CONCLUSION:Although laparoscopic adjustable gastric banding surgery has few short-term risks and is highly effective at achieving weight reduction, we found an increased risk for major respiratory complications in the long-term period. The obesity epidemic and the increased use of surgical techniques to treat obesity will most likely lead to an increase in the incidence of long-term post-operative respiratory complications. This entity is probably under-reported and needs further research into how to reduce its incidence and morbidity.
