Laparoscopic treatment of a gastro-gastric fistula after Roux-en-Y gastric bypass-report of two cases. J Surg Case Rep. 2020;2020(12):rjaa478. doi:10.1093/jscr/rjaa4782042-8812http://hdl.handle.net/10400.16/2668The most frequently performed bariatric surgery is the laparoscopic Roux-en-Y gastric bypass (LRYGB). An uncommon complication of LRYGB is gastro-gastric fistula (GGF). Possible causes of GGF include incomplete transection of the stomach during the initial surgery, staple-line leaks in the post-operative period and marginal ulcers. The optimal management of GGF is still under debate, with medical, endoscopic and surgical treatment modalities available. The authors present two cases of a GGF successfully managed with a laparoscopic surgical approach, after failed medical and endoscopic treatment.engjournal article10.1093/jscr/rjaa478
