Bariatric surgeries have been increasing in prevalence as the obesity epidemic climbs in the United States. As with any surgery, bariatric procedures come with their respective risks and complications which are generally well depicted in radiological studies. Traditionally, fluoroscopy has been an accepted form of evaluating anatomy, obstruction, and leaks. With the rise in cross sectional imaging methods, abdominal computed tomography (CT) has provided much more specificity to identify and characterize major complications. This review article will demonstrate the imaging findings and complications of the most common bariatric surgeries performed in the southeast United States at a single, large tertiary care center: Roux-en-Y gastric bypass, adjustable gastric band, and sleeve gastrectomy. This image-rich comprehensive review presents the radiological manifestations of the anatomy and potential complications of these bariatric surgeries primarily through the modalities of CT and CT-angiography (CTA) with the occasional assistance of fluoroscopy. It is crucial for general radiologists, emergency medicine physicians, and surgeons to recognize these imaging findings as they will frequently encounter patients with complications in their clinical settings. While one anastomosis gastric bypass (OAGB) and single-anastomosis duodenal-ileal switch (SAIDS) surgeries are other recognized bariatric procedures, these are not commonly performed regionally and therefore post-operative images of these procedures and complications are excluded.
随着美国肥胖症流行情况加剧，减肥手术的普及率一直在上升。与任何手术一样，减肥手术都有其各自的风险和并发症，这些在放射学研究中通常都有详细描述。传统上，荧光镜检查一直是评估解剖结构、梗阻和渗漏的一种公认方法。随着横断面成像方法的兴起，腹部计算机断层扫描（CT）在识别和描述主要并发症方面提供了更高的特异性。这篇综述文章将展示在美国东南部一家大型三级医疗中心进行的最常见减肥手术的影像学表现和并发症：Roux-en-Y胃旁路术、可调节胃束带术和袖状胃切除术。这篇内容丰富的综合综述主要通过CT和CT血管造影（CTA）的方式，并偶尔借助荧光镜检查，展示了这些减肥手术的解剖结构和潜在并发症的放射学表现。对于普通放射科医生、急诊医学医生和外科医生来说，认识这些影像学表现至关重要，因为他们在临床环境中经常会遇到有并发症的患者。虽然单吻合口胃旁路术（OAGB）和单吻合口十二指肠回肠转位术（SAIDS）手术是其他公认的减肥手术，但这些手术在该地区并不常见，因此排除了这些手术及其并发症的术后影像。
