To demonstrate the use of a Roth net and to determine the maximum number of coins that can be removed per net.
During esophagogastroduodenoscopy, a Roth net was passed multiple times in order to retrieve 49 ingested coins without the use of an over tube.
Removal of 49 coins of various sizes was accomplished. The largest of the coins was 2.4 cm. Because of damage to the nets during the withdrawal past the gastroesophageal junction, several nets were required. But, there was minimal trauma to the esophageal mucosa and no complications.
Removal of ingested foreign objects requires individually tailored treatment. From an extensive literature search, there does not appear to be consensus for standard of care based on the variability of presentation and multiple modalities available for removal.
演示Roth网的使用方法，并确定每个网可取出的硬币最大数量。
在食管胃十二指肠镜检查期间，多次使用Roth网，以便在不使用外套管的情况下取出49枚吞食的硬币。
成功取出了49枚大小各异的硬币。最大的硬币直径为2.4厘米。由于在将网从胃食管交界处撤出时网受到损坏，因此需要使用多个网。但是，食管黏膜的创伤极小，且未出现并发症。
取出吞食的异物需要进行个体化治疗。通过广泛的文献检索，基于临床表现的变异性和多种可用的取出方式，似乎尚未达成护理标准的共识。
