About this trial
Radiofrequency ablation has been used for treatment of solid neoplasms of the liver, lung, kidney and adrenal. Recently, EUS-guided RFA has become available and the device allows EUS-guided treatment of solid abdominal neoplasms. The procedure has been shown to be feasible in the porcine pancreas and was used to treat small groups of patients that are not suitable for surgery suffering from pancreatic cancers.
The aim of the current study is to perform a multi-center prospective study on EUS-guided radiofrequency ablation (RFA) of solid abdominal neoplasms. The hypothesis is that EUS-guided RFA is safe, feasible and effective for treating solid abdominal neoplasms.

Single group
Treatments tested in this trial
EUS-guided RFA
DeviceAll patients would undergo EUS with a linear array echoendoscope. The location and size of the lesion would be assessed for suitability of treatment. After locating the lesion, the RFA needle would be inserted to the centre of the lesion. RFA would then be initiated and hyperechoic interferences would be observed around the electrode signifying heating of the tissue. The duration of ablation would be according to the size of the lesion.

Severe adverse events
Adverse events specific to RFA would be graded according to the lexicon of endoscopic adverse events 24. Potential adverse events specific to RFA include: post-RFA syndrome, pancreatitis, pancreatic leak and thermal injury.
Secondary outcomes
Technical success rates
defined as successful puncture of the lesion with the RFA needle and completion of the ablation cycle.
