Abstract

Objective: To assess the usefulness of peritoneal cavity scintigraphy and the contribution of SPECT/CT in patients on peritoneal dialysis with suspected leak.

Methodology: An observational case series study is carried out. It consists of a longitudinal, retrospective and descriptive study. 11 patients on peritoneal dialysis were studied and it was realiced a peritoneal cavity scintigraphy test and SPECT/CT to evaluate a peritoneal leak.

Results: In 54,5% of the patients, a positive study of peritoneal leak was obtained. The most frequent localitations were in the abdominal wall at the catheter entry level and the inguinal hernia. In the cases with sintomatology like pain and celullitis of the subcutaneous tract of the cateter the frequent of leak was 100%. There was a change in therapeutic management in patients with a positive study. There was not relevant changes in initial dialysis regimen in patients with a negative study. In this cases, except for one patient who required hemodialysis, all patients experienced clinical improvement.

Conclusions: Peritoneal scintigraphy and SPECT/CT study are non-invasive techniques that allow an adequate diagnosis and subsequent management of peritoneal leak.

腹膜闪烁扫描和 SPECT/TC 在腹膜透析患者渗漏诊断中的应用。
目的评估腹腔闪烁扫描在腹膜透析疑似渗漏患者中的作用以及 SPECT/CT 的贡献:进行一项观察性病例系列研究。研究包括纵向、回顾性和描述性研究。对 11 名腹膜透析患者进行了研究,并通过腹腔闪烁扫描检查和 SPECT/CT 评估腹膜渗漏情况:结果:54.5%的患者腹膜渗漏检查结果呈阳性。最常见的位置是导管入口处的腹壁和腹股沟疝。在导尿管皮下组织有疼痛和糜烂等症状的病例中,腹漏发生率为 100%。研究结果呈阳性的患者的治疗方法有所改变。阴性患者的初始透析方案没有相关变化。在这些病例中,除了一名患者需要进行血液透析外,所有患者的临床症状都有所改善:结论:腹膜闪烁照相术和 SPECT/CT 研究都是非侵入性技术,可对腹膜渗漏进行充分诊断和后续处理。
