目的

探讨校正后低体质量指数(body mass index, BMI)对门静脉高压症患者经颈静脉肝内门体分流术(transjugular intrahepatic portosystemic shunt, TIPS)预后的影响。

方法

回顾性分析2019年3月至2022年12月于中国科学技术大学附属第一医院行TIPS治疗的157例门静脉高压症患者。基于术前校正后BMI(根据腹水程度校正体质量:轻度-5%、中度-10%、重度-15%,伴外周水肿额外-5%)分为营养不良组(M组,校正BMI<18.5 kg/m2n=79)和非营养不良组(nM组,n=78),比较两组术后肝性脑病(hepatic encephalopathy, HE)发生率及生存率差异。中位随访时间39(15-60)个月。

结果

TIPS术后1年内,M组总体HE(43.00% vs. 21.80%, χ2=8.864, P=0.003)及显性HE发生率(25.30% vs. 9.60%, χ2=6.305, P=0.012)均显著高于nM组,两组隐匿性HE发生率差异无统计学意义(22.80% vs. 13.30%, P=0.098)。随访结束时,M组生存率低于nM组(77.60% vs. 80.80%, χ2=4.706, P=0.030)。

结论

以校正后低体质量指数(BMI<18.5 kg/m2)界定的营养不良在门静脉高压症TIPS治疗患者中的发生率高达50.32%。营养不良可显著增加术后HE风险并降低生存率,是影响TIPS预后的独立危险因素。临床需重视术前基于校正BMI的营养评估及干预,以改善患者结局。

Objective

To investigate the correlation between low adjusted body mass index (BMI) and the prognosis of patients with portal hypertension undergoing transjugular intrahepatic portosystemic shunt (TIPS).

Methods

A retrospective analysis was conducted on 157 patients with portal hypertension who underwent TIPS at the First Affiliated Hospital of University of Science and Technology of China from March 2019 to December 2022. Based on pre-procedure BMI adjusted for ascites (mild: -5%, moderate: -10%, severe: -15%, plus an additional -5% for peripheral edema), patients were divided into a malnutrition group (M group, adjusted BMI < 18.5 kg/m2, n=79) and a non-malnutrition group (nM group, n=78). Postoperative incidence of hepatic encephalopathy (HE) and survival rates were compared. The median follow-up was 39 months (range: 15–60 months).

Results

Within one year after TIPS, the M group showed a significantly higher incidence of overall HE (43.00% vs. 21.80%, χ2= 8.864, P=0.003) and overt HE (25.30% vs. 9.60%, χ2= 6.305, P=0.012) compared to the nM group. No significant difference was found in the incidence of covert HE (22.80% vs. 13.30%, P=0.098). At the end of follow-up, the survival rate in the M group was significantly lower than in the nM group (77.60% vs. 80.80%, χ2= 4.706, P=0.030).

Conclusion

Malnutrition, defined by adjusted BMI<18.5 kg/m2, occurred in 50.32% of patients undergoing TIPS for portal hypertension. Malnutrition could increase the risk of post-procedure HE and reduce survival, serving as an independent risk factor for TIPS prognosis.
