About this study

the left lobe of the liver in obese patient usually fatty and enlarged and may cause difficulty during bariatric surgery. the aim of this study is to test the impact of routine preoperative ultrasound to evaluate the size of left lobe of the liver as a preoperative predictor for difficulty. two equal groups of patients are operated by laparoscopic sleeve gastrectomy with loop bipartition, in one group routine abdominal ultrasound is done, in the other group ultrasound not routinely done.
