Objectives:
To prospectively assess the frequency of severe abdominal pain during and after transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) using the visual analog scale (VAS), and to identify predictive factors.
Methods:
Ninety-eight TACE performed in 80 patients (mean 65 ± 12 years old, 60 men) were consecutively and prospectively included. Abdominal pain was considered severe if the VAS ≥ 30/100 after treatment administration, or if opioid analgesic (grades 2-3) intake was required during hospitalization. Patient and tumor characteristics as well as technical factors associated with severe pain were identified by binary logistic regression.
Results:
The criterion for severe pain was met in 41/98 (42%) of procedures (peri-procedural pain 30/98 [31%] and opioid consumption during hospitalization 24/98 [25%]). Multivariate analysis identified age (odds ratio [OR] = 0.943 (95% confidence interval 0.895-0.994), p = 0.029), cirrhosis (OR = 0.284 (0.083-0.971), p = 0.045), and alcoholic liver disease (OR = 0.081 (0.010-0.659), p = 0.019) as negative predictive factors of severe abdominal pain. Severe abdominal pain occurred in or after 1/13 (8%), 8/34 (24%), 22/41 (54%), and 10/10 (100%) TACE sessions when none, one, two, and three of the protective factors were absent, respectively (p < 0.001). The area under the ROC curve of the combination of factors for the prediction of severe abdominal pain was 0.779 (CI 0.687-0.871).
Conclusion:
Severe abdominal pain was frequent during and after TACE revealing a clinically relevant and underestimated problem. A predictive model based on three readily available clinical variables suggests that young patients without alcoholic liver disease or cirrhosis could benefit from reinforced analgesia.
Key Points:
• Severe abdominal pain occurs in 43% of TACE for HCC. • Younger age, absence of cirrhosis, and absence of alcoholic liver disease were identified as independent predictive factors of severe abdominal pain. • A simple combination of the three abovementioned features helped predict the occurrence of severe abdominal pain.

Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
