Thrombotic complications following bariatric surgery: how medical tourism poses challenges to comprehensive care in obesity medicine

The global prevalence of obesity has more than tripled since 1975. Unfortunately, bariatric surgery waiting lists can last many years therefore many patients seek alternative options such as “medical tourism” by venturing abroad for surgery. We describe two cases of porto-mesenteric venous thrombosis in patients who travelled abroad for bariatric surgery. Upon returning both cases required interventional radiological management, and in the first case, the patient underwent a small bowel resection for bowel ischaemia. Porto-mesenteric complications are significant and have profound lifelong consequences. Therefore, it is imperative that patient education is significantly improved, and more stringent regulations by health authorities are put in place to avoid the growing complications of negative health tourism.
