View Poster


Erectile dysfunction (ED) is a mistreated and neglected complication that affects 35%-75% of males with type 2 diabetes (T2DM) leading to worsening quality of life and interpersonal relations. Males with T2DM develop ED 5-10 years earlier than non-diabetics. This study aims to observe the ED prevalence before and after 12 months of laparoscopic ileal interposition associated to sleeve gastrectomy (II-SG) evaluated by a questionnaire, to evaluate global sexual function 12 months after the procedure and compare with initial parameters and to analyze if diabetes duration was an interfering factor in sexual function improvement 12 months after the surgery.


This was a prospective, longitudinal and observational study including 50 consecutive male patients with T2DM and a body mass index (BMI)


Mean age was 54.4 years (37-69). Mean diabetes duration was 12, 1 years (05-23 years). Mean HbA1c was 8, 8 % (7, 5-10, 5%). After 12 months, we observed a significant improvement in glycemic control, dyslipidemia, blood pressure and a reduction in the use of insulin and anti-diabetic agents (p


Ileal Interposition associated to sleeve gastrectomy, significantly improved erectile function, satisfaction with sexual intercourse, orgasmic function, sexual desire and sexual life of patients with type 2 diabetes 1 year after the surgery.
