Read the detailed description

Waist to height raito is the major determinator of patients and will be noted in every patient who will fulfil the eligibility criteras defined below and undergo laparoscopic sleeve gastrectomy. demographic data, BMI, body lipid composition, lean body weight also will be noted. all patients will undergo standardized laparoscopic sleeve gastrectomy operation. patients will be follow up during first, third, sixth and one year periods. all parameters noted preoperatively will be measured and noted again. possible statistical difference will be calculated statistically and a cut off value will be seeked.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 19, 2016, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
