What is new in bariatric and metabolic surgery

I am pleased to introduce this special series on “Bariatric and Metabolic Surgery”. Present series includes all recognised available standard techniques and their modifications in bariatric surgery starting from gastric banding to more complex procedures like duodenal switch. Direct issues related to bariatric surgery like enhanced recovery after surgery (ERAS) and weight regain after surgery were also included. We have a special chapter on metabolic effects of bariatric surgery on type 2 diabetes and all effects were discussed in details. Andominal wall surgery in bariatric patients also discussed in details by Morales Conde in this special series.

This special series also includes the abstract from the 3rd Turkish National Congress on Bariatric and Metabolic Surgery.

I would like to thank all authors for their tremendous efforts to make this series ready during the COVID-19 pandemia. I also would like to thank the journal staff especially Brad…. Without him this work will never end.

I hope this will create new horizons in your surgical view.
