The number of bariatric surgery procedures performed is increasing every year. Patients may be referred for radiological investigations to exclude complications not only in the early postoperative period but many months later. Radiologists who do not work in bariatric centres are therefore required to have an understanding of the complex normal anatomy and complications associated with bariatric surgery to interpret imaging studies correctly. The purpose of this article is to describe the surgical techniques and normal anatomy of the four bariatric operations performed today, review the most common problems encountered in this patient group, and to describe the imaging findings that allow the accurate diagnosis of complications. In particular, we focus on identification of the internal hernia, a grave complication of bariatric surgery often missed by radiologists.
每年进行的减肥手术数量都在增加。患者可能需要进行放射学检查以排除不仅在术后早期，而且在术后数月后出现的并发症。因此，不在减肥中心工作的放射科医生需要了解与减肥手术相关的复杂正常解剖结构和并发症，以正确解读影像学研究。本文的目的是描述当今四种减肥手术的手术技术和正常解剖结构，回顾该患者群体中最常见的问题，并描述可准确诊断并发症的影像学发现。特别是，我们专注于识别内疝，这是减肥手术的严重并发症，经常被放射科医生漏诊。
