Developmental phase



Assessment

Primary outcomes

The degree of bodily injury, self-consciousness and distress was evaluated using the VAS scale for comparison of SLC versus MLC.

1352

Results

Curability had the highest score (49.9 53.7 points), followed by safety (23.8 24.7 points). The scores for cosmetic outcomes (6.2 7.1 points) were almost equal to those of the length of hospital stay (6.2 7.1 points), which was associated with medical costs and pain (10.0 11.1 points), one of the main reasons for fear of surgery. Participants who were female, younger, and in the nonmedical group placed great importance on cosmetic outcomes.

Baseline Characteristics

We used a web-based questionnaire to survey nonmedical and medical workers for what factors were considered on the
assumption that respondents undergo colorectal cancer surgery and that the most important person for them undergoes. Five items
(curability, safety, pain, length of hospital stay, and cosmetic outcomes) were compared. After paired photographs before and after
SLS and MLS were shown, perceptions of body image and cosmesis were assessed using a visual analog scale.

Outcome measures

The respondents were to assume that they and the most important person for them were undergoing surgery and rank the factors according to the importance of each outcome, with total scores summed to 100 points. The abdominal photographs of consecutive patients who underwent laparoscopic surgery for colorectal cancer at Osaka University, Sapporo Medical University, and National Hospital Organization Osaka National Hospital were collected to evaluate the differences in the perception of body image and cosmesis between SLS and MLS. A total of 32 patients photographs before and after surgery were used in this study (20 patients who underwent SLS and 12 patients who underwent MLS). Photographs of 1 patient before and after the surgery were grouped, and the pairs from SLS and MLS were randomly shown on the website. The perceptions of body image and cosmesis were assessed using a visual analog scale . The respondent was to assume the wound was theirs and answer previously reported questions with the following responses: dissatisfied with appearance, difficult to see self naked, less physically attractive, and body damage from surgery.21 This study also added the following simple questions: Does the wound worry you? and Which age group is suitable for SLS? In addition, 3 questions compared SLS and MLS: Which wound is good-looking?, Which surgical procedure do you want to undergo?, and Which surgical procedure do you want for the most important person for you to undergo?
