“…Accordingly, some investigators [2,3,14] have used the visual analog scale (score of 1 to 10) as a tool for assessment of cosmetic outcome, without appropriate validation process. In comparison, we used the Body Image Questionnaire, a well-validated tool that has been used to assess cosmetic satisfaction after surgery in previous studies involving ileocolectomy [9,15], proctectomy [16,17], nephrectomy [18], splenectomy [19], cholecystectomy [20,21], appendectomy [22], and hepatic resection [23]. We believe that the use of this validated tool is important to reveal a small but definite difference in cosmetic satisfaction after single-port laparoscopy.…”
