The effect of bariatric surgery on weight loss and improvement of co-morbidities is no longer doubted. However, little attention has been given to the treatment goals from the patient's point of view (patient expectations). The objective of this study was to examine patients' expectations of bariatric surgery and identify gender differences.
Bariatric patients were asked to complete a questionnaire. Statistical analysis was performed using chi-square, Pearson correlation coefficient, and Wilcoxon rank sum test.
Overall, 248 patients participated in this study (69.4% females). The male patients (45.2 yr, SD±11.1) were significantly older than the female (41.8 yr, SD±12.0; P = .04) and suffered significantly more often from diabetes, hypertension, hypercholesterolemia, and sleep apnea. One hundred thirty patients (52.4%) expected to lose at least 45 kg and 39 patients (15.7%)>70 kg. The mean expected excess weight loss was 71.8%. Females expected significantly more often that surgery alone would induce weight loss (P = .03). "Improved co-morbidity" was by far the highest ranked parameter.
The male bariatric surgery patients were older and suffered from more co-morbidities. Most of the patients had unrealistic weight loss goals and overestimated the effect of the surgical intervention. However, for both female and male patients, "improved co-morbidity" was the most important issue.
减重手术对体重减轻及合并症改善的效果已毋庸置疑。然而，从患者角度（患者期望）对治疗目标的关注却很少。本研究的目的是调查患者对减重手术的期望并确定性别差异。
要求减重手术患者完成一份问卷。使用卡方检验、Pearson相关系数和Wilcoxon秩和检验进行统计分析。
总体而言，248名患者参与了本研究（女性占69.4%）。男性患者（45.2岁，标准差±11.1）明显比女性（41.8岁，标准差±12.0；P = 0.04）年龄大，且患糖尿病、高血压、高胆固醇血症和睡眠呼吸暂停的频率明显更高。130名患者（52.4%）期望至少减重45千克，39名患者（15.7%）期望减重超过70千克。预期平均额外体重减轻为71.8%。女性更常期望仅通过手术就能减重（P = 0.03）。“合并症改善”是迄今为止排名最高的参数。
接受减重手术的男性患者年龄更大，合并症更多。大多数患者有不切实际的减重目标，且高估了手术干预的效果。然而，对于女性和男性患者来说，“合并症改善”都是最重要的问题。
