Introduction
Bariatric surgery is the most effective treatment modality in morbidly obese patients. Compared to Roux-en Y gastric bypass (RYGB), sleeve gastrectomy (SG) has better metabolic and nutritional outcomes after surgery. Exocrine pancreatic insufficiency (EPI) can be seen after RYGB but there is not any knowledge about EPI-SG association.

Aim
To assess exocrine pancreatic functions before and after the SG procedure.

Material and methods
This is a single-center, prospective and case-control study. Forty morbidly obese patients were included in the study. Their pre-operative and post-operative, third month fecal samples were collected. Exocrine pancreatic insufficiency was determined by using fecal elastase-1 and diagnosed when fecal elastase-1 levels were < 200 µg/g.

Results
The mean fecal elastase-1 level was 256.25 ±137.16 µg/g and the mean post-surgical fecal elastase-1 level was 437.7 ±212.43 µg/g (p = 0.001). In the pre-operative period, half of patients had FE levels under 200 µg/g. In the third month after surgery, only 4 patients had fecal elastase-1 levels under 200 µg/g. Comparison of fecal elastase-1 between pre-surgery and post-surgery revealed a significant difference (p = 0.001).

Conclusions
This is the first study to investigate EPI-SG association. Surgery-associated morbidity and mortality are the leading limitations of bariatric surgery procedures. Exocrine pancreatic insufficiency is one of them; prior studies demonstrate its increased frequency after RYGB. Our study revealed that SG relieves exocrine pancreatic insufficiency.
