Six-Year Evaluation of Same-Day Discharge following Conventional Transarterial Chemoembolization of Hepatocellular Carcinoma.

PURPOSE: To evaluate whether same-day discharge increased the incidence of 30-day readmission (30dR) after conventional transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) at a single institution. MATERIALS AND METHODS: In this retrospective study, 253 patients with HCC underwent 521 transarterial chemoembolization procedures between 2013 and 2020. TACE was performed with 50-mg doxorubicin/10-mg mitomycin C/5-10-mL ethiodized oil/particles. Patients not requiring intravenous pain medications were discharged after a 3-hour observation, and 30dR was tracked. The primary objective was to determine the incidence of 30dR in same-day discharge patients versus patients admitted for observation using the chi-square test. Secondary objectives assessed factors associated with overnight admission and factors predictive of 30dR using generalized estimated equation calculations and logistic regression. RESULTS: In the cohort, 24 readmissions occurred within 30 days (4.6%). Same-day discharge was completed after 331 TACE procedures with sixteen 30dRs (4.8%). Patients admitted overnight were readmitted 8 times after 190 TACE procedures (4.2%). This difference was not statistically significant (P = .4). Factors predicting overnight admission included female sex (58/190 [30.5%] vs 58/331 [17.5%], P < .001) and tumor size of ≥3.8 cm (104/190 [55%] vs 85/190 [45%]). Factors predicting 30dR included female sex (10/116 [8.6%] vs 14/405 [0.2%]) and younger age (median [interquartile range], 63 years [55-65 years] vs 65 years [59-71 years]). At regression, factors predictive of 30dR were Child-Pugh Class B/C (odds ratio [OR], 2.1; P = .04) and female sex (OR, 2.9; P = .004). CONCLUSIONS: Same-day discharge after conventional TACE is a safe and effective strategy with 30dR rate of <5%, similar to overnight observation.

Hepatobiliary cancers, version 2.2014.

Hepatobiliary cancers include a spectrum of invasive carcinomas arising in the liver (hepatocellular carcinoma), gall bladder, and bile ducts (cholangiocarcinomas). Gallbladder cancer and cholangiocarcinomas are collectively known as biliary tract cancers. Gallbladder cancer is the most common and aggressive type of all the biliary tract cancers. Cholangiocarcinomas are diagnosed throughout the biliary tree and are typically classified as either intrahepatic or extrahepatic cholangiocarcinoma. Extrahepatic cholangiocarcinomas are more common than intrahepatic cholangiocarcinomas. This manuscript focuses on the clinical management of patients with gallbladder cancer and cholangiocarcinomas (intrahepatic and extrahepatic).

Use of percutaneous drainage to treat hepatic abscess after radiofrequency ablation of metastatic pancreatic adenocarcinoma.

Radiofrequency ablation (RFA) is well described in the treatment of primary hepatic malignancies and colorectal carcinoma hepatic metastases. A known complication of RFA is the development of hepatic abscess. The management of hepatic abscesses subsequent to RFA for metastatic disease is not well described. A 49-year-old female with pancreatic adenocarcinoma underwent pancreaticoduodenectomy followed by adjuvant chemoradiation. Following 6 months' treatment, a new liver metastasis was identified. It remained stable for 6 months during additional chemotherapy and thereafter was treated with RFA. Three weeks after RFA, the patient presented with malaise and leukocytosis, and a CT scan demonstrated a large hepatic abscess at the site of the RFA. She remained febrile despite needle aspiration and intravenous antibiotics. A percutaneous drain was placed and the symptoms resolved. Contrast injection of the drain 4 weeks later demonstrated resolution of the abscess cavity but communication with the biliary tree. The drain was removed and the tract embolized with Gel-foam to prevent complications of biliary-cutaneous fistula. She remains well without evidence of abscess or disease recurrence. Thus, RFA can be used in treatment of limited isolated hepatic metastases from previously treated pancreatic adenocarcinoma. However, the incidence of hepatic abscess is increased due to bilioenteric anastomosis; extended antibiotic prophylaxis should be considered.

Gastrointestinal complications associated with hepatic arterial Yttrium-90 microsphere therapy.

Hepatic arterial therapy with yttrium-90 microspheres exploits the avenue provided by the neoplastic microvasculature to deliver high-energy, low-penetrating therapeutic doses of radiation. Variant hepatic arterial anatomy, collateral vessels, and changes in flow dynamics during treatment can affect particle dispersion and lead to nontarget particle distribution and subsequent gastrointestinal morbidity. Awareness of these variances and techniques to prevent gastrointestinal tract microsphere delivery is essential in mitigating this serious complication. Our aim is to increase the understanding of the role of various imaging and preventative techniques in minimizing this undesired effect.

Treatment of SVC syndrome and hemoptysis in a patient with mediastinal fibrosis.

Mediastinal fibrosis can present with a multitude of symptoms, most commonly cough, dyspnea and hemoptysis. We describe a case of mediastinal fibrosis secondary to histoplasmosis, which presented with both superior vena cava syndrome (SVCS) and hemoptysis. Our patient was successfully treated with bronchial artery embolization followed by SVC stent placement during a brief hospital stay.

Aortoiliac occlusive disease in patients with known or suspected peripheral vascular disease: safety and efficacy of gadofosveset-enhanced MR angiography--multicenter comparative phase III study.

PURPOSE: To prospectively determine the safety and efficacy of the gadolinium-based blood pool magnetic resonance (MR) imaging contrast agent gadofosveset in patients known to have or suspected of having peripheral vascular disease. MATERIALS AND METHODS: Ethical committee approval and patient written informed consent were obtained. This study was compliant with the Health Insurance Portability and Accountability Act. Adults known or suspected to have peripheral vascular disease received gadofosveset (0.03 mmol per kilogram of body weight) for MR angiography of the aortoiliac region. Gadofosveset-enhanced MR angiography and unenhanced two-dimensional time-of-flight MR angiography were compared with the reference standard, conventional angiography, for the presence of vascular stenosis. All patients were monitored for adverse events with hematologic analysis, analysis of blood chemistry, urinalysis, and electrocardiographic parameters; these methods were analyzed to determine safety. RESULTS: A total of 274 patients were enrolled at 37 centers. Gadofosveset-enhanced MR angiography showed significant improvement (P < .001) compared with unenhanced MR angiography for each of the readers for diagnosis of clinically significant (> or = 50%) stenosis. Specificity and accuracy were significantly greater for three readers, and sensitivity increased significantly for two readers. For all readers, the area under the receiver operator characteristic curve for both quantitative and qualitative measures of significant disease increased (P < .001) for gadofosveset-enhanced MR angiography versus two-dimensional time-of-flight MR angiography. All readers also expressed more confidence in diagnosis (P < .001) and found fewer images to be uninterpretable (0.5% vs 11.0%). The most common adverse events were as follows: feeling hot, 12 (4.4%) patients; nausea, 10 (3.6%) patients; headache, nine (3.3%) patients; and burning sensation, eight (2.9%) patients. Only four serious adverse events were reported, in three patients, and all events were rated as unlikely related to the drug. No patients were excluded because of adverse events or laboratory abnormalities. There were no clinically important trends in the findings of hematologic analysis, blood chemistry, urinalysis, electrocardiography, or physical examination. CONCLUSION: On the basis of substantial improvements over non-contrast MR angiography in efficacy and a minimal and transient side-effect profile, gadofosveset was found to be safe and effective for MR angiography in patients known or suspected to have peripheral vascular disease.
