  • Cardiovascular Complications of Terminal Stage Cirrhosis and Related Clinical Significance

    Objective To introduce the clinical significance and pathophysiologic aspects of the circulatory and cardiac complications in terminal stage cirrhosis. Methods Recently relevant literatures were reviewed and summarized. Results Haemodynamic changes in cirrhosis arose on the basis of combined humoral and nervous dysregulation, with abnormalities in cardiovascular regulation, volume distribution and cardiac performance. Conclusion Comprehending the mechanisms of cardiovascular complications will contribute a lot for the treatment of terminal stage cirrhosis.

  • 肝动脉化疗栓塞术后发生胆汁瘤1例报道

      患者,女,42岁,因肝血管瘤行肝动脉化疗栓塞(TACE)后8个月,皮肤、巩膜黄染及肝内多发囊性占位4个月入院。患者入院前12个月MRI发现肝多发血管瘤(图1),最大3.5 cm×7 cm,无不适。入院前8个月行血管瘤TACE,术中予碘油16 ml栓塞,术后感乏力、纳差、肝区隐痛,化验“ALT 292 U/L、Bil正常”,予以甘利欣、凯西莱等治疗,ALT有所下降,但始终不正常。入院前4个月出现皮肤及巩膜黄染、尿黄,化验“ALT 153.2 U/L, TBil 95 μmol/L, DBil 79.9 μmol/L”, B超: “肝血管瘤栓塞术后,肝内囊性占位”,应用胆维他、优思弗、思美泰等治疗,黄疸进行性加重,肝内囊性占位进行性增大入我院。化验肝功能: Alb 31 g/L, TBil 172.8 μmol/L, DBil 139.8 μmol/L,ALT 58 U/L, AST 97 U/L, ALP 321 U/L, GGT 238 U/L。B超: ①肝内多发囊性占位; ②肝大、脾大; ③血管瘤。CT(图2): ①肝血管瘤栓塞术后改变; ②肝内多发囊性低密度影; ③脾大。诊断: ①肝内多发性囊性占位,胆汁瘤可能; ②肝血管瘤。遂行肝移植术,术后恢复良好。已切除病肝见囊肿内容物为混浊的有“渣”胆汁,分房状,不与胆管相通。病理提示: 病肝组织部分区域见内衬扁平细胞的由扩张血管构成的瘤样组织,少数管腔内含血栓成分; 部分区域间肝内和小胆管内多发性结石,并见较多胆汁湖形成,其周边部较易见泡沫细胞及巨嗜细胞,其余背景肝组织内部分肝细胞及毛细胆管侧胆汁淤积,毛细胆栓形成,较多胆管及细胆管增生,纤维组织增生并包绕肝小叶,部分区域见假小叶形成,内见胆管结石及部分残留胆管壁。诊断: ①肝海绵状血管瘤; ②肝内及小胆管内多发性胆管结石,继发性胆汁性肝硬变; ③胆汁瘤。 图1 MR示介入前多发血管瘤;图2 示介入后9个月肝内多发胆汁瘤(白箭为胆汁瘤,黑箭为血管瘤)。2A: 血管瘤和胆汁瘤; 2B: 胆汁瘤   讨论 TACE是医源性胆汁瘤的常见原因,其形成机理是由于TAE和(或)PEI的理化作用导致肿瘤或相应区域肝内胆管坏死。胆管周围毛细血管丛受损,可导致胆管坏死,胆汁经坏死的胆管漏向肝实质内,积聚成囊者为囊状胆汁瘤,沿坏死的胆管壁积聚者为柱状胆汁瘤。若囊肿与胆管的瘘口封闭则囊肿内壁内皮化,并产生分泌功能,分泌液体积蓄,导致囊肿越来越大; 较大的囊肿可压迫毗邻的胆管,使之梗塞,形成“软藤状”的胆管扩张。如果囊肿与胆管潜在相通,则在达到一定压力时,囊肿内液体进入胆管内,故囊肿不会明显增大。另一方面,这类与胆管相通的囊肿,因不断有胆汁在囊肿压力较低时自胆管进入囊肿,故引流亦未必能有效缩小囊肿。本例患者为肝血管瘤栓塞治疗后形成胆汁瘤,其CT平扫表现为椭圆形或分叶状的低密度病灶,其密度接近于胆囊内的密度,囊壁菲薄而不易发现,增强后扫描囊内不强化,囊壁不强化或轻度强化。故肝血管瘤行栓塞治疗方法值得进一步商榷。因此凡是反复进行TAE、PEI治疗的患者一般情况稳定,突然并发梗阻性黄疸,CT提示肝内囊性占位,应考虑有胆汁瘤形成的可能。

  • Evaluation of the clinical effect of surgical intervention combined with endoscopic ultrasound-guided transluminal drainage in the treatment of infectious pancreatic necrosis: a retrospective, historical control study

    ObjectiveTo evaluate the clinical efficacy of surgical intervention combined with endoscopic ultrasound-guided transluminal drainage in the treatment of infected pancreatic necrosis (IPN). MethodsA retrospective, historical control study was conducted. A total of 98 patients with acute pancreatitis (AP) complicated with IPN who met the inclusion and exclusion criteria and were admitted to the Third People’s Hospital of Chengdu from June 2016 to January 2023 were selected as the research objects. The endoscopic ultrasound-guided transluminal drainage was carried out in our hospital in June 2020. In this study, patients treated before May 2020 were divided into the non-EUS group (52 cases), and patients treated after June 2020 were divided into the EUS group (46 cases). The baseline data, surgical intervention, length of hospital stay, length of intensive care unit (ICU) stay, infection time, incidence of multiple organ dysfunction syndrome (MODS), survival situation, short-term and long-term complications, and other indicators were compared between the two groups. ResultsThe number of percutaneous catheter drainage (PCD, 1.0 vs. 1.0), the number of PCD drainage tube (1.0 vs. 2.0), the number of retroperitoneal debridement drainage (1.0 vs. 2.0), the total length of hospital stay (42.0 d vs. 45.5 d), the length of ICU stay (11.0 d vs. 14.0 d), the length of infection time (10.5 d vs. 18.5 d), the incidences of MODS [43.5% (20/46) vs. 67.3% (35/52)] and residual infection [28.3% (13/46) vs.48.1% (25/52)] in the EUS group were shorter (or lower) than those in the non-EUS group (P<0.05); but there were no significant differences in the number of endoscopic pancreatic stent implantation, the number of laparotomy, the number of laparoscopic surgery, and the incidences of abdominal bleeding, gastrointestinal fistula, gastrointestinal obstruction, chronic pancreatic fistula, chronic pancreatitis and incisional hernia between the two groups (P>0.05). ConclusionFor patients with AP complicated with IPN, surgical intervention combined with endoscopic ultrasound-guided transluminal drainage can reduce the number of PCD and drainage tube, shorten the total length of hospital stay, the length of ICU stay and infection, as well as reduce the incidences of MODS and residual infection.
