Assessment of body image alteration after renal surgery using a novel three-dimensional laser scanner

Abstract

Objectives To evaluate the utility of a newly developed three-dimensional (3D) body surface laser scanner and evaluate the body surface image of patients undergoing renal surgery to determine the impact of surgery on body image alterations. Methods The body surface image in the upright position was obtained using the Bodyline Scanner (Hamamatsu Photonics K.K., Hamamatsu, Japan), a 3D body surface laser scanner, in 27 patients who had undergone renal surgery. We compared the objective results of body image scanning with the subjective results of a self-administered questionnaire on perception and concern about body image alteration. Results The abdominal body surface area and volume of the operative side was significantly larger than that of the contralateral side in 18 patients undergoing renal surgery using a flank incision (median area 50.7%, P = 0.002; volume 51.2%, P <0.001). A statistically significant difference was not observed in 9 patients undergoing transperitoneal or laparoscopic surgery (median area 50.0%, P = 0.34; volume 49.9%, P = 0.40). The volume alteration measured by the 3D body surface laser scanner correlated with the patients' perception ( P = 0.01) and concern ( P = 0.03) about postoperative body image alteration as assessed by the self-administered questionnaire. Conclusions The 3D body surface scanner is promising as a tool in the medical field in that it enables a computerized body image to be constructed in the upright position that reflects patients' subjective perceptions well. Using this, we observed that the flank incision causes postoperative changes in body image perceptible to the patient and a cause for concern.
