Brief Summary:
This study aims to evaluate the safety and efficacy of new ablation catheter developed by MEDICAL TAEWOONG for the treatment of pancreatic neoplasm (pancreatic adenocarcinoma or neuroendocrine tumour). The ablation is performed using EUSRA needle and radio frequency waves under ultrasound imaging. The subject who will be recruited into this study are patients who are deemed as non-surgical candidates.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 10 participants
Intervention Model: Single Group Assignment
Intervention Model Description: prospective, open label
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Evaluation of Safety and Feasibility of Endoscopic Ultrasound (EUS)-Guided Radiofrequency Ablation (RFA) for Solid Pancreatic Neoplasms
Estimated Study Start Date : March 1, 2018
Estimated Primary Completion Date : September 1, 2019
Estimated Study Completion Date : September 1, 2019

Arm Intervention/treatment
Experimental: EUSRA RFA needle
This procedure is very similar to the standard technique of EUS-guided fine needle aspiration. All patients would undergo EUS with a linear array or therapeutic echoendoscope. The location and size of the lesion would be assessed for suitability of treatment. After locating the lesion, the EUSRA 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.
Device: EUSRA RFA needle
A 19-gauge RFA electrode and a RF generator with a electrode that is needle-shaped and echogenic that allows EUS guided puncture of the target lesion. The active electrode tip is 1 cm in length. During ablation, the RF electrode is cooled and perfused internally with circulating chilled saline solution (0°C) delivered via a pump to maintain a constant temperature. A setting of 50W energy would be used for RFA and the duration of application is 10 seconds. Sequential applications of up to 7 times per session are allowed for complete ablation of the lesions.

Primary Outcome Measures :
  1. To measure the technical success of EUS-guided RFA [ Time Frame: 18 months ]
    It is defined as successful puncture of the pancreatic lesion with the RFA needle and completion of the ablation cycle.

  2. To measure side effects and adverse event of EUS-guided RFA [ Time Frame: 18 months ]

    Adverse events specific to RFA would be graded according to the lexicon of endoscopic adverse events (PB Cotton GIE 2010). Potential adverse events specific to RFA include:

    • Post-RFA syndrome: Combination of flu like symptoms including fever, malaise, pain at the site of ablation, nausea, and/or vomiting and that no other septic source is identified.
    • Pancreatitis: Clinical presence of abdominal pain with an increase in amylase level >3 times above the normal serum amylase levels.
    • Pancreatic leak: The presence of an abdominal collection with an amylase level that is >3 times normal serum amylase levels.
    • Thermal injury: Coagulative necrosis occurring at the site of needle entry within the gastrointestinal tract with or without clinical sequelae.
