About this study

Official title: Per-oral Pancreatoscopy-guided Lithotripsy vs. Extracorporeal Shock Wave Lithotripsy in Chronic Pancreatitis

This is a multi-center randomized controlled trial comparing extracorporeal shock-wave lithotripsy (ESWL) with per-oral pancreatoscopy-guided lithotripsy (PPL) in the treatment of patients with chronic pancreatitis and refractory main pancreatic duct stones. This study will be comparing the two treatment options for patients who have stones that fail initial endoscopic therapy via endoscopic retrograde pancreatography (ERCP). The study will look at the stone clearance rates and patient-centered outcomes including quality of life and pain.

Read the detailed description

Patients with chronic pancreatitis frequently develop obstructing pancreatic duct stones which can lead to severe pain. Current standard methods to remove these stones include ERCP and extracorporeal shock-wave lithotripsy (ESWL) which are limited in removing larger and multiple impacted stones. Availability in the USA of ESWL for this indication also may be limited even at major referral centers. The introduction of single-operator per-oral pancreatoscopy (SpyGlassTM) has enabled direct intraductal visualization to target stones. Retrospective studies demonstrate a high success rate but literature is quite limited, uncontrolled, and highly selective. Further, many experts and recent European Society Guidelines suggest that ESWL is the only primary therapy for larger stones (5mm or larger) and that intraductal endoscopy and lithotripsy should only be used for 'salvage' therapy in select patients.

A critical need exists to compare the efficacy of per oral pancreatoscopy-guided lithotripsy (PPL) with ESWL to determine which therapy is most efficacious in removing refractory PD stones. The investigators believe ERCP with POP has distinct advantages of localizing 'shocks' to the stones, helping to identify and treat underlying strictures in the duct, and lithotripsy of multiple stones can be performed at a single session with a recent multi-center international retrospective study showing all stones removed in a single session in over 70% of cases. Therefore, this project seeks to change the perceived standard of care as it relates to symptomatic pancreatic duct stones in this population, shifting the pendulum towards endoscopic and specifically pancreatoscopy-guided therapy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Per-oral Pancreatoscopy-guided LithotripsyProcedure or surgery

    Per-oral Pancreatoscopy-guided lithotripsy will be administered for a maximum of 4 sessions (1 hour max per session). Either electrohydraulic lithotripsy or laser lithotripsy will be allowed during the session at the discretion of the endoscopist.

  • Extracorporeal Shock-Wave LithotripsyProcedure or surgery

    ESWL will then be performed with the patient in either slight left or right lateral decubitus with shock waves entering the body from the ventral side. The shockwaves will be focused first on the most distally located stone within the main duct and then on other calculi moving from the head towards the body. If a stent has been inserted during preceding ERP then this may also serve as a guide to target main pancreatic duct stones by ESWL. A total of one hour of ESWL at a rate of 60-120 shocks/minute will be delivered in one treatment session.

Per-oral Pancreatoscopy-guided LithotripsyActive comparatorStandard ERP will be performed to cannulate the PD, perform pancreatic sphincterotomy, and stricture dilation as necessary. A pancreatoscope (Spyglass Digital System, Boston Scientific, Marlborough, MA) will then be inserted through the duodenoscope into the PD. For PPL, electrical pulses will be delivered through an aqueous medium by EHL or LL with the probe tip in contact with or 1-2mm away from the stone. Settings for EHL (1.9F fiber; Autolith, Northgate Technologies, Elgin, IL) are 10-20 pulses/second with a power of 50-100; and for LL (200, 272, or 365 micrometer fiber, Versa Pulse Power Suite 20-W Holmium laser, New Star, Roseville, CA) ranging from 0.8 - 2.5 Joules with a frequency of 8-15Hz and power of 9-30 W. A maximum of 1 hour of intraductal lithotripsy will be allowed to reduce performance bias.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Stone Clearance Rate

    The rate of complete clearance of the main pancreatic duct of all stones.

    Measured: Up to 4 hours (four 1-hour sessions)

Secondary outcomes (2)
  1. Change In Quality of Life as Measured Using PANQOLI Score

    Change in quality of life as measured using the PANQOLI (PANcreatitis Quality of Life Instrument), a chronic pancreatitis-specific quality of life instrument. This instrument has a score range from 0 to 100, which higher scores denoting better quality of life. The questionnaire has 18 items and questions 1, 2, 3, 4, 5, 6, 12, 13, 14, 15, 16, 17, and 18 are reverse scored while items 7, 8, 9, 10, and 11 are scored at face value. The final score is the sum of the scores from all 18 questions.

    Measured: At the conclusion of treatment success/failure at 1,3,6, and 12 months follow-up

  2. Change in Pain Levels as Measured Using the COMPAT Score

    Change in pain levels as measured using the comprehensive pain assessment tool, (COMPAT), a chronic pancreatitis-specific pain questionnaire. The questionnaire consists of 23 questions. A score is assessed for question # 14, which consists of 28 questions with scores ranging from 0 to 10, with 10 representing worse pain. A maximum score of 280 is possible for this component of the COMPAT.

    Measured: At the conclusion of treatment success/failure at 1,3,6, and 12 months follow-up
