Purpose: To retrospectively evaluate the efficacy and safety of computed tomography (CT)-guided percutaneous gastrostomy in patients presenting with complications after bariatric surgery.

Materials and Methods: From January 2003 up to today, 25 patients (20 women), formerly operated for severe obesity, were referred for gastrostomy, after presenting with a complication. The mean age and body mass index were 38±9.3 years and 46±7.1 kg/m2, respectively. A gastrostomy tube was placed under CT in all patients.

Results: The procedure's technical success rate was 96%, with mean interventional time of 80±42 minutes. In 14 of 25 (56%) cases submucosal spread of air was noticed during air insufflation into the stomach. No major complications were recorded. There was a statistically significant improvement of both albumin and prealbumin values compared with the initial ones (P<0.005).

Conclusions: CT-guided gastrostomy in patients with complications after bariatric surgery, provides a reliable alternative for nutritional support. It restores the normal absorption route, reversing metabolic deficiencies.
