Purpose

The aim of this study was to evaluate the incidence and the CT findings of sleeve gastrectomy (SG) complications in a multi-centric experience, in order to improve confidence with radiologic pattern of the more common complications.

Methods and materials

In the present study were included 147 patients undergone SG for obesity in the period between 2017 and 2018 and sent to our attention for upper gastrointestinal (UGI) or CT examination in order to rule out post-SG complications. UGI examination was realized with patient in supine and supine left posterior oblique positions. MDCT examination was performed with Siemens Somatom-Dual energy (128 slices) after contrast medium intravenous injection (3.0 cc/Kg); CT imaging acquisition was scanned during the venous phase. Main CT findings were retrospectively analysed.

Results

In our cohort of patients, the main complications were: leaks and gastric stricture resulted from edema or ischemia; out of 147 patients, 7 showed staple line leaks and 5 presented gastric strictures and the incidence rate was 4,67% for leaks and 3,4 % for gastric stricture. No significant difference between UGI and MDCT examination was found in specificity (95% and 100%, respectively), but MDCT revealed a higher sensitivity than UGI (95%vs79%).

Conclusion

UGI and MDCT are both valuable tools in the detection of complications with equal diagnostic yield. MDCT showed higher accuracy and was able to add information about collateral pathologic findings as the presence of fluid collections or abscess.
