A balloon technique has been developed for measurement of the pouch volume and stoma diameter after gastroplasty. Twenty-seven patients prospectively included in a randomized study of two types of gastroplasty operation have been investigated 6 months postoperatively. During the operation the proximal pouch was calibrated to be about 40 ml and the stoma diameter to 11 min. Six months after the operation the patients had on average reduced weight by 29 kg. Using the balloon technique, the stoma diameter was 12 +/- 1.6 (s.e.m.) mm and the pouch volume 80 +/- 11.0 ml. There was a significant correlation between the stoma diameter and weight reduction during the first 6 months postoperatively (P less than 0.01). The relationship between the stoma diameter and weight reduction followed best an exponential equation. No correlation was found between the pouch volume and weight reduction. The presented technique for measurement of pouch volume and stoma diameter after gastroplasty may be an important tool to evaluate the influence of various factors on the long-term results of surgical treatment for morbid obesity.
已经开发出一种气囊技术，用于测量胃成形术后的胃囊容积和造口直径。对前瞻性纳入两种胃成形术随机研究的27例患者在术后6个月进行了调查。手术过程中，近端胃囊校准为约40毫升，造口直径为11毫米。术后6个月，患者平均体重减轻了29千克。使用气囊技术，造口直径为12±1.6（标准误）毫米，胃囊容积为80±11.0毫升。术后前6个月造口直径与体重减轻之间存在显著相关性（P<0.01）。造口直径与体重减轻之间的关系最符合指数方程。未发现胃囊容积与体重减轻之间存在相关性。所介绍的胃成形术后测量胃囊容积和造口直径的技术可能是评估各种因素对病态肥胖手术治疗长期结果影响的重要工具。
