Abstract

Introduction-Aim: Facing the failures of the medical management of obesity, bariatric surgery offers a promising therapeutic option. The aim of our study was to study the evolution of anthropometric parameters five years after sleeve gastrectomy.

Methods: This was a prospective longitudinal descriptive study conducted at the obesity research unit of the National Institute of Nutrition in Tunis on obese patients who had undergone weight loss surgery. At 5 years post-operatively, the patients answered questionnaires assessing eating behavior, eating disorders, taste, smell, appetite, food preferences and anxiety-depressive disorders and the anthropometric parameters were measured.

Results: We included 30 patients aged 43.2 ± 9.57 years. The average weight increased from 133.04 ± 18.36 kg to 94.63 ± 19.81 kg after five years, an average weight reduction of 28.8% compared to the initial weight (p-10-3). We noted a statistically significant negative correlation between preoperative fat mass and excess weight loss (PEP) (r=-0.79; p-10-3). The correlation between the depression score and the PEP was statistically significant, the higher the depression score, the lower the PEP (r= -0.48; p=0.007). However, no statistically significant correlation was found between anxiety score and PEP.

Conclusion: The mid-term weight loss results after sleeve gastrectomy were satisfying. However, it would be interesting to continue the research with larger-scale studies.
