BACKGROUND
Endoscopic treatment of gastric leaks (GL) following sleeve gastrectomy (SG) involves different techniques; however, standard management is not yet established. We report our experience about endoscopic internal drainage of leaks using pigtail stents coupled with enteral nutrition (EDEN) for 4 to 6 weeks until healing is achieved.

METHODS
In 21 pts (18 F, 41 years), one or two plastic pigtail stents were delivered across the leak 25.6 days (4-98) post-surgery. In all patients, nasojejunal tube was inserted. Check endoscopy was done at 4 to 6 weeks with either restenting if persistent leak, or removal if no extravasation of contrast in peritoneal cavity, or closure with an Over-the-Scope Clip® (OTSC®) if contrast opacifying the crossing stent without concomitant peritoneal extravasation.

RESULTS
Twenty-one out of 21 (100 %) patients underwent check endoscopy at average of 30.15 days (26-45) from stenting. In 7/21 (33.3 %) patients leak sealed, 2/7 needed OTSC®. Second check endoscopy, 26.7 days (25-42) later, showed sealed leak in 10 out 14; 6/10 had OTSC®. Four required restenting. One patient, 28 days later, needed OTSC®. One healed at 135 days and another 180 days after four and seven changes, respectively. One patient is currently under treatment. In 20/21 (95.2 %), GL have healed with EID treatment of 55.5 days (26-?180); all are asymptomatic on a normal diet at average follow-up of 150.3 days (20-276).

CONCLUSIONS
EDEN is a promising therapeutic approach for treating leaks following SG. Multiple endoscopic sessions may be required.
