Background
Endoscopic stents are successful in the management of surgical leaks; however, stent migration remains a significant problem. In this study, we present our approach depending on a large bariatrics-specific stent (Mega stent) and over-the-scope clips in the management of post-bariatric surgery leaks.
Methods
A retrospective analysis of all patients with post-bariatric surgery leaks treated at our institution using an approach reliant on Mega stents and over-the-scope clips was conducted. Potential factors associated with procedure success and occurrence of complications were also evaluated.
Results
A total of 81 stents were inserted in 62 patients with post-bariatric surgery leaks, 46 sleeve gastrectomies (73%) and 16 Roux-en-Y gastric bypass (27%). Over-the-scope clips were applied in 29 patients (46%). Leak closure was achieved in 51 patients (82%). Median number of procedures per patient was 3 (range 2–8). Complications included the following: stent migration (11/62, 18%), intolerance necessitating premature removal (7/62, 11%), esophageal stricture (8/62, 13%), bleeding (4/62, 6%), perforation (4/62, 6%). One stent-induced mortality was encountered (bleeding). The presence of open surgery (vs laparoscopic) was significantly associated with the occurrence of stent-induced complications (p 0.002).
Conclusion
The approach combining Mega stents and over-the-scope clips is highly effective in the management of post-bariatric surgery leaks and is associated with a low rate of stent migration and a low number of procedures and stents per patient. Mega stents, however, should be used with great caution due to the significant morbidity associated with their use.
