摘要
背景：原发性硬化性胆管炎（PSC）与胆道梗阻有关，需要进行内镜逆行胰胆管造影术（ERCP）。虽然ERCP的有益效果有据可查，但后续介入策略却不太明确，其长期影响也存在争议：我们评估了ERCP引导下介入治疗计划的效果，该计划已在我们的三级肝病中心制定并实施了20多年。在我们中心，每隔一段时间都会进行ERCP随访，以治疗之前发现的形态学狭窄，而与临床症状无关。我们计算了参加定期ERCP计划的患者的无移植生存率（TFS），并将其与仅根据临床需求接受随访ERCP的患者进行了比较。此外，我们还记录了肝功能失代偿、胆管炎复发、肝胆恶性肿瘤和内镜相关不良事件的发生情况：在这项回顾性研究中，我们共纳入了 201 名 PSC 患者，他们都接受了 ERCP。其中，133 名患者接受了预定的 ERCP 随访，68 名患者仅根据需要接受了 ERCP 随访。与按需接受ERCP的患者相比，按计划接受ERCP的患者自初次诊断以来的TFS率（中位数TFS：17年 vs. 27年；P = 0.020）和初次发病率（中位数TFS：16年 vs. 11年；P = 0.002）更高。亚组分析显示，与没有进展的患者相比，第一次和第二次ERCP之间胆管造影结果的进展与较差的预后有关（17年 vs. 未定义；P = 0.021）：总之，我们报告了在一家经验丰富的大容量内镜中心对PSC患者进行定期随访ERCP计划的结果数据。我们的数据建议启动多中心随机对照前瞻性试验，以探索定期内镜随访治疗作为预防 PSC 患者疾病进展策略的全部潜力。
Long-term impact of scheduled regular endoscopic interventions for patients with primary sclerosing cholangitis.
Background: Primary sclerosing cholangitis (PSC) is associated with biliary obstructions that can require endoscopic retrograde cholangiopancreatography (ERCP). While the beneficial effects of ERCP are well documented, follow-up interventional strategies are less defined, and their long-term impact is debated.
Methods: We evaluated the outcome of a scheduled program of ERCP-guided interventions that have been developed and implemented at our tertiary liver center for more than 20 years. Within our center, follow-up ERCPs were performed at regular intervals to treat previously detected morphological stenosis independent of clinical symptoms. We calculated the transplant-free survival (TFS) of patients who were enrolled in the scheduled ERCP program and compared it to patients who received follow-up ERCPs only on clinical demand. Moreover, we documented the occurrence of hepatic decompensation, recurrent cholangitis episodes, hepatobiliary malignancies, and endoscopy-related adverse events.
Results: In our retrospective study, we included 201 patients with PSC who all received an ERCP. In all, 133 patients received scheduled follow-up ERCPs and 68 received follow-up ERCPs only on demand. The rates of TFS since initial diagnosis (median TFS: 17 vs. 27 y; P = 0.020) and initial presentation (median TFS: 16 vs. 11 y; P = 0.002) were higher in patients receiving scheduled versus on-demand ERCP. Subgroup analysis revealed that progression in cholangiographic findings between the first and second ERCP was associated with a poorer outcome compared to patients without progression (17 y vs. undefined; P = 0.021).
Conclusion: In conclusion, we report the outcome data of a scheduled follow-up ERCP program for patients with PSC in an experienced high-volume endoscopy center. Our data suggest the initiation of multicenter randomized controlled prospective trials to explore the full potential of regular endoscopic follow-up treatment as a strategy to prevent disease progression in patients with PSC.
