A computerized search was made of all publications on jejunoileal bypass for obesity, recorded in Index Medicus during 1963 to 1977. A total of 171 references, dealing with 6319 patients were usable for the purpose. Fifty-three variables were registered. The great majority of publications is American and published since 1972. Only 20% are joint publications from collaborating surgical and medical departments. The study draws attention to a number of quantitative and qualitative deficiencies in the data and to the less expedient way they are sometimes presented. Principally, this applies to patient number and description, length of observation time, and frequency of complications. Lack of specified criteria for surgical eligibility is common, as is ambiguity in conclusion. It is suggested that recommendations, positive or negative, reflect the authors' subjective attitude, as they are apparently made from the same objective data.
对1963年至1977年《医学索引》中记录的所有关于空回肠分流术治疗肥胖症的出版物进行了计算机检索。共有171篇参考文献可供使用，涉及6319名患者。记录了53个变量。绝大多数出版物是美国的，且自1972年以来发表。只有20%是外科和内科合作部门的联合出版物。该研究提请注意数据中存在的一些数量和质量方面的缺陷，以及有时呈现数据的不太合适的方式。主要适用于患者数量和描述、观察时间长度以及并发症发生率。缺乏明确的手术适应症标准很常见，结论也含糊不清。有人认为，无论是肯定还是否定的建议，都反映了作者的主观态度，因为它们显然是基于相同的客观数据得出的。
