Nesidioblastosis following laparoscopic sleeve gastrectomy.

Hyperinsulinaemic hypoglycaemia due to nesidioblastosis after bariatric surgery is a rare but well documented complication of roux-en-y gastric bypass (RYGB). We report the first documented case of nesidioblastosis following laparoscopic sleeve gastrectomy. This is a timely report as sleeve gastrectomy is now the most commonly performed bariatric procedure, accounting for 52.5% of bariatric procedures performed in Australia between 2014- 2015 . This case is important as nesidioblastosis is not a previously reported complication of sleeve gastrectomy. It therefore expands our understanding of the effect of surgically induced changes to incretin secretion following sleeve gastrectomy.
