Brief Summary

As bleeding is a major risk in bariatric surgeries, The study aimed to find any predictors to such bleeding within the surgery or 30 days after surgery. The study is a retrospective study collecting patients data, surgeons data, and hospitals data in order to find if any of the factors influencing patients, surgeons or hospitals, has to do with bleeding in these surgeries and if it does impact bleeding in what way. The goal is finding a predictor that it's neutralizing may prevent bleeding in bariatric surgeries.
