[Acute abdominal symptoms in patients with a gastric band].

Three women aged 32, 35 and 37 years, respectively, presented with upper abdominal symptoms such as pain, nausea and vomiting. Their history revealed that an adjustable silicone gastric band had been implanted for the treatment of obesity one, four and seven years previously. Their symptoms were not immediately recognised as being possible complications of the gastric band and this caused treatment delay. In the first two patients ischaemic lesions were found at laparotomy. Their surgical treatment was successful. The third patient, however, was referred to the surgeon who had placed the gastric band, but she died in the mean time. Lack of recognition of symptoms caused by gastric banding and delay in diagnostic and therapeutic intervention may lead to very serious complications, or even death. Good diagnostic imaging and prompt therapeutic intervention can prevent the progression from herniation of the stomach through the silicone gastric band to irreversible ischaemia and eventually necrosis and perforation.
