A case of laparoscopic revision surgery 30 years after vertical banded gastroplasty for morbid obesity.

As the number of bariatric and metabolic surgeries being performed is increasing, the importance of revision surgeries is escalating. In this report, we describe a case of revision surgery performed 30 years after vertical banded gastroplasty (VBG), including a review of the surgical techniques. The patient was a male in his 50s who had previously undergone VBG for morbid obesity (body mass index of 72.6 kg/m ), resulting in gradual weight loss. Twenty-eight years later, reflux symptoms due to stenosis of the mesh area developed. Despite conservative treatment, the symptoms recurred, and aspiration pneumonia developed. Gastrojejunal and Y-anastomoses were performed laparoscopically. Postoperatively, the patient progressed well with no weight regain. In revision surgery, it is essential to accurately assess the patient's pathophysiology, as the surgical technique must consider improvement in symptoms, risk of weight regain, and the need for observation of the residual stomach.
