Radiological Investigations in Vertical Banded Gastroplasty Patients

In our institute we have performed 124 vertical banded gastroplasties. Patients with a follow-up beyond 3 months were studied with a barium meal, in order to evaluate the efficiency of surgery and the eventual complications. Seventy-nine patients have had one or more X-ray investigations at various times after surgery (for a total of 136 studies). The first 20 patients were routinely studied at 1, 2 and 3 years after the operation; the next 32 patients were studied for features such as vomiting, poor weight loss or low food intake; the last 27 patients were studied with an early overlook beginning 3 months after surgery. We noted gastroesophageal reflux in eight (10.1%) cases, outlet dilatation in four (5%) cases, outlet substenosis (diameter 6-8 mm) in 13 (16.4%) cases, outlet stenosis (diameter
