Laparoscopic and open pyloromyotomies are equally safe and effective, with the principal benefit of laparoscopy being better cosmesis. The goal of this study was to measure the perceived value of laparoscopic pyloromyotomy.
Four hundred sixteen subjects (177 college freshmen, 126 first-year medical students, and 101 parents) were asked to complete a questionnaire after photographs of mature pyloromyotomy (open and laparoscopic) scars were shown to them. To measure the perceived value, subjects' willingness to pay hypothetical additional out-of-pocket expenses for their preferred operation was assessed. Data were analyzed using Cochran-Mantel-Haenszel test, t test and multivariable regression.
Four hundred four surveys were complete. Overall, 74% preferred the appearance after laparoscopy. Eighty-eight percent would pay an additional out-of-pocket amount for their daughter and 85% for their son to have the cosmetic outcome after laparoscopy. Respondents were willing to pay more for their daughters (P < .0001) and sons (P < .0001) than themselves. As expected, income level (P < .0001) influenced the willingness to pay, whereas ethnicity, education, number of children, and sex did not.
The cosmetic benefit of laparoscopic pyloromyotomy was valued by a wide demographic with 85% being willing to pay additional expenses for their children to have smaller scars.
腹腔镜幽门肌切开术和开放幽门肌切开术同样安全有效，腹腔镜手术的主要优势在于美容效果更好。本研究的目的是评估腹腔镜幽门肌切开术的感知价值。
向416名受试者（177名大学新生、126名一年级医学生和101名家长）展示成熟的幽门肌切开术（开放和腹腔镜）疤痕照片后，要求他们完成一份问卷。为了评估感知价值，评估了受试者为其首选手术支付假设额外自付费用的意愿。使用 Cochr an - Mantel - Haenszel检验、t检验和多变量回归分析数据。
共完成404份调查。总体而言，74%的人更喜欢腹腔镜手术后的外观。88%的人愿意为女儿额外支付自付费用，85%的人愿意为儿子支付额外费用，以使他们在腹腔镜手术后获得美容效果。受访者为女儿（P <.0001）和儿子（P <.0001）支付的意愿高于为自己支付的意愿。正如预期的那样，收入水平（P <.0001）影响支付意愿，而种族、教育程度、子女数量和性别则没有影响。
腹腔镜幽门肌切开术的美容益处受到广泛人群的重视，85%的人愿意为孩子支付额外费用以获得更小的疤痕。
