Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Patients with liver tumors who underwent US-guided-MWA of liver tumors were enrolled. These patients were allocated into three groups based on tumor size and number: A, B, and C. Prior to the ablation procedure, Group A patients received a combination of hepatic hilar block (HHB), Transversus abdominis plane block (TAPB), and local anesthesia (LA). Patients in Group B were administered HHB in conjunction with LA, while those in Group C received TAPB and LA. Evaluative parameters included the Numerical Rating Scale (NRS) scores, consumption of morphine, incidence of complications, and factors influencing perioperative pain.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients with liver tumors who underwent US-guided-MWA of liver tumors were enrolled. These patients were allocated into three groups based on tumor size and number: A, B, and C. Prior to the ablation procedure, Group A patients received a combination of hepatic hilar block (HHB), Transversus abdominis plane block (TAPB), and local anesthesia (LA). Patients in Group B were administered HHB in conjunction with LA, while those in Group C received TAPB and LA.Pain levels were routinely assessed through the Numerical Rating Scale (NRS), with scores being recorded by the attending nurse every 15 minutes. The frequency of these assessments would be increased if the patient reported discomfort or if there were changes observed in vital signs. If a patient reported a pain level of ≥4 on the NRS scale, an intravenous dose of 10mg morphine was administered, provided that cardiopulmonary safety could be assured. The determination of cardiopulmonary safety was made by the interventional radiologist (M. L. with 20 years of experience). Following the ablation procedure, all patients were monitored for a period of 36 hours. During this period, several parameters were recorded at the time of the procedure and again at 4, 8-, 12-, 24-, and 36-hours post-procedure. These parameters included the NRS score, vital signs, any need for morphine, and the occurrence of any adverse events.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

Primary hepatic carcinoma was considered if characterized by a solitary tumor (≤5cm in maximum diameter) or by the presence of multiple tumors (2-3 in number, each ≤3cm in maximum diameter). Importantly, these tumors were required to be devoid of vascular invasion, biliary intrusion, contiguous organ invasion, or any evidence of distant metastasis.

Another group included in the study were patients with hepatic metastases, limited to no more than 5 tumors each measuring ≤3cm in maximum diameter.

Furthermore, patients with hepatic hemangioma were also considered for inclusion. Specific criteria applied in these cases included tumors larger than 5cm in maximum diameter that showed considerable growth (imaging findings suggest that the diameter of the tumor has increased by more than 1cm) in the preceding two years and were associated with persistent hemangioma-related abdominal pain or discomfort. Alternatively, tumors measuring up to 5cm in maximum diameter, exhibiting a pronounced growth propensity and located at the first, second, or third hilar region in close proximity to the hilar bile duct, portal vein, hepatic artery, hepatic vein, or inferior vena cava were also considered. And all these patients cannot tolerate surgery due to other organ damage or do not want to undergo surgical treatment.

The ASA grade is II or III.

Exclusion Criteria

Patients with severe underlying medical conditions that could potentially prevent them from tolerating the US-guided MWA procedure were ruled out.

Those with tumors invading blood vessels, bile ducts, adjacent organs, or presenting with extrahepatic metastasis were also excluded.

Further, any cases presenting with uncorrectable coagulation disorders, thrombocytopenia, or currently under administration of anticoagulant agents were deemed unfit for the study.

Finally, patients were excluded if a safe trajectory for executing US-guided MWA was not feasible.
