Area of Science:

  • Bariatric Surgery
  • Medical Technology
  • Body Image Research

Background:

  • Many patients undergoing bariatric surgery retain a distorted self-perception despite significant weight loss.
  • Post-surgical body image issues can impact patient well-being and long-term outcomes.
  • Existing interventions may not fully address the psychological aspects of weight loss.

Purpose of the Study:

  • To assess the efficacy of a 3D modeling tool in enhancing body image perception in patients post-bariatric surgery.
  • To determine if 3D visualization can help patients align their perceived body with their actual post-surgical physique.
  • To explore the potential of 3D modeling as a clinical tool for managing body image concerns.

Main Methods:

  • Prospective inclusion of 140 adult patients (post-Roux en Y Gastric Bypass or sleeve gastrectomy) during follow-up.
  • Assessment of body image using the Figure Rating Scale (FRS) before and after 3D avatar visualization.
  • Statistical analysis including Pearson's chi-squared test to compare groups (p < 0.05).

Main Results:

  • Nearly half of participants adjusted their body perception after viewing their 3D avatar.
  • One-third of patients showed a reduced FRS score (improved perception) post-visualization.
  • A significant correlation was observed between FRS score and Body Mass Index (BMI), strengthening after 3D avatar viewing.

Conclusions:

  • A 3D modeling tool shows promise in improving body perception for bariatric surgery patients.
  • The tool's simplicity, non-invasiveness, and ease of use support its potential widespread clinical implementation.
  • Further research is warranted to evaluate its impact on mood, eating disorders, and overall surgical success.
