RELATIONSHIP BETWEEN PRE-OPERATIVE BODY MASS INDEX AND LENGTH OF OPERATION OF LAPAROSCOPIC SLEEVE GASTRECTOMY

Background:The BMI has been investigated as one of risk factors of perioperative and postoperative complications. However, the BMI effect on intraoperative and duration of laparoscopic Sleeve gastrectomy had not been addressed in literature.Methods:This study is a part of retrospective cohort conducted in (), correlation analysis was used to detect the relationship between duration of LSG and BMI. We used Kendall’s tau correlation for the relationship between two non-normally distributed variables, otherwise the Pearson’s correlation was used. A significant correlation is considered when P-value is less than 0.05. For pair wise comparisons of continuous variable, Mann Whitney test was used for non-parametric data otherwise, t-test was used to detect the difference between two groups. Results:Based on our results, there was no significant relationship between the BMI and length of the operation (P-value = 0.85) or whether long or short surgery based on BMI (P-value = 0.58). Furthermore, no difference in BMI between those who had intraoperative complications and those who had not (P-value = 0.57).Conclusion:The Body Mass Index (BMI) did not have effect on the duration of LSG and intraoperative complications.
