This study was undertaken to determine the optimal radiologic examination techniques for the period immediately following gastric restrictive surgery to control obesity. Review of 450 examinations performed on 275 patients who underwent varied gastric restrictive procedures indicates that accurate evaluation requires prompt filming of the first swallow of contrast material in a specific initial patient position with only minimal fluoroscopic monitoring. It was found that the optimal patient position can be predicted, before contrast material is administered, by the orientation of the staples on an abdominal radiograph. Right posterior oblique (RPO) is the optimal starting position when vertical staple lines follow gastroplasty with a lesser curvature channel. Left posterior oblique (LPO) is optimal when horizontal staple lines follow gastroplasty. LPO is usually optimal when complex or confusing staple patterns follow gastric bypass operations and revisions of previous procedures to control obesity. However, RPO is the optimal orientation when the revision procedure is a vertical gastroplasty.
本研究旨在确定胃限制性手术后立即用于控制肥胖的最佳放射学检查技术。对275例接受不同胃限制性手术的患者进行的450次检查回顾表明，准确评估需要在特定的初始患者体位下，仅在最少的荧光透视监测下，对造影剂的首次吞咽进行快速拍摄。研究发现，在给予造影剂之前，可通过腹部X线片上吻合钉的方向预测最佳患者体位。当垂直吻合钉线沿胃成形术且有较小弯曲通道时，右后斜位（RPO）是最佳起始体位。当水平吻合钉线沿胃成形术时，左后斜位（LPO）是最佳体位。当复杂或混乱的吻合钉模式出现在胃旁路手术及之前控制肥胖的手术的翻修术中时，LPO通常是最佳体位。然而，当翻修手术为垂直胃成形术时，RPO是最佳体位。
