Plain English Summary
Background and study aims
Chronic pancreatitis (CP) is a condition where the pancreas becomes permanently damaged from inflammation, causing severe pain. Surgery is kept as a last resort when other treatments have failed and the severity of disease has increased substantially and pain becomes unmanageable. Small studies have suggested that early surgery may be beneficial in terms of pain relief and pancreatic function. The aim of this study is to evaluate the benefits, risks and costs of early surgery as an alternative to current practice for CP.
Who can participate?
Patients with CP being treated with opioid painkillers.
What does the study involve?
Participants are randomly allocated to either group A or group B. Group A undergo early surgical treatment, while group B follow the current step-up practice (medical management followed by endoscopic treatment followed by surgical treatment if not effective).
What are the possible benefits and risks of participating?
Every treatment has its risks for complications.
Where is the study run from?
Academic Medical Centre Amsterdam (Netherlands).
When is the study starting and how long is it expected to run for?
April 2011 to July 2017.
Who is funding the study?
1. Dutch Digestive Diseases Foundation (Netherlands)
2. ZonMw Health Care Efficiency Research Program (Netherlands)

Scientific title
Early Surgery versus optimal Current step-up prActice for chronic PancrEatitis (ESCAPE): a multi-centre randomised controlled trial
Acronym
ESCAPE
Study hypothesis
Early surgical intervention results in less pain over the study period and is more cost-effective than the optimal current step-up practice.

Condition
Chronic pancreatitis
Intervention
Early surgical intervention:
Surgical drainage of the pancreatic duct (pancreaticojejunostomy) if pancreatic head is not enlarged (< 4 cm) or surgical drainage of the pancreatic duct and resection of the head of the pancreas (Frey procedure) if pancreatic head is enlarged (4cm)
Control group: Optimal current step-up practice
1. Step 1 - Optimal medical management, if not effective followed by
2. Step 2 -Endoscopic intervention, and if not effective followed by
3. Step 3 - Surgical intervention
The patient follow-up will be completed 18 months after randomisation for the primary endpoint, the secondary endpoints and the other research questions.

Primary outcome measure
The primary clinical outcome is the degree of pain as assessed by the Izbicki pain score at 2 weeks intervals during the follow-up period of 18 months
Secondary outcome measures
1. Cost-effectiveness, total direct and indirect costs-during 18 months follow-up period
2. Severe complications related to disease progression or endoscopic and surgical interventions
2.1. Mortality (all-cause)
2.2. Disease progression: development of pseudocysts, pancreatic insufficiency (endocrine or exocrine), gastric outlet or duodenal obstruction, chronic use of opioids (defined as need for opioids for a period > 6 months), hospital admissions for CP upflares
2.3. Endoscopic intervention: (acute) pancreatitis flare up, cholangitis, acute cholecystitis, retroperitioneal or bowel perforation, abdominal sepsis, intra-abdominal abscesses needing intervention, bleeding needing transfusion or intervention, any relaparotomy for other reasons
2.4. Surgical intervention: anastomotic leakage, bleeding needing transfusion or intervention, abdominal sepsis, intra-abdominal abscesses needing intervention, burst abdomen, severe wound infection (requiring prolonged hospital stay), any relaparotomy for other reasons
3. Quality of life-assessed by validated questionnaires.
4. Izbicki score at 18 months follow-up
5. Endocrine pancreatic insufficiency-determined by use of anti-diabetic medication or abnormal serum glucose levels (fasting serum glucose levels > 6,0 mmol/L in capillary blood or > 6,9 mmol/L in venous plasma at two different days
6. Exocrine pancreatic insufficiency-determined by fecal elastase levels (< 200µg/g)
7. Additional pain measurements-due to the heterogeneity in reporting of pain in previous trials and in order for the results of this trial to be comparable with other important trials in literature, the following additional measures of pain will be reported as well:
7.1. Proportion of patients with complete and partial pain relief at end of follow-up, defined as follows:
7.1.1. Complete pain relief: an Izbicki pain score = 10 points
7.1.2. Partial pain relief: a decrease of >50% from baseline in the Izbicki score with a final score >10 points
7.2. Visual analogue score (VAS) for pain: measured as part of the Izbicki score
7.3. Büchler pain score: alternative pain measure based on the Izbicki questionnaire, and calculated by the multiplication of two of the four items of the Izbicki questionnaire (i.e. pain frequency and pain intensity)
8. Number and duration of hospital admissions during study period-Total number of hospital admission during 18 months of follow-up period and days outside the hospital in 18 months of follow-up
9. Number of performed interventions-total number of endoscopic and surgical interventions, including initial intervention.
10. Number of pancreatitis flare ups during study period-total number during 18 months follow-up period documented by computed tomography (CT) or magnetic resonance imaging (MRI)

Eligibility
Participant inclusion criteria
Registration criteria:

1. Need for upgrade from non-opioids to opioid analgesics: newly developed need for opioids analgesics (opioids needed at least 3 days per week) and persistently needed for at least 2 weeks in a row
2. Informed consent for randomisation
