Timestops (4)

Topic Overview

A multidisciplinary discussion on pancreatic function testing and pain management in pediatric chronic pancreatitis. The session covers direct pancreatic function testing via endoscopic collection after secretin stimulation, emerging MR-based quantitative assessment of exocrine function, and the critical role of integrated pain psychology in managing these patients. A case presentation demonstrates how addressing psychosocial factors and family dynamics can defer major surgery in a child with chronic pancreatitis.

Key Takeaways

  • Endoscopic pancreatic function testing replaced drilling method by 2000s, using secretin stimulation with duodenal aspirates q5min x3 (2:07)
  • MR-based pancreatic function testing quantifies secreted fluid volume by subtracting pre-secretin from post-secretin imaging at 15min (5:18)
  • Low-fat diet, PERT, antioxidants, and steroids have never been proven to prevent recurrent pancreatitis or pain episodes (12:05)
  • Psychology involvement via cognitive behavioral therapy is mandatory 100% of time in pain management, not optional (15:24)
  • Pancreatic function testing can be falsely abnormal if performed around acute attack; function matures over first 2-3 years of life (4:25)

Open questions

  • What is the normal range for MR-based quantitative pancreatic function testing in pediatric patients, and does it vary by age, size, or weight?
  • How well does MR-based quantitative fluid secretion correlate with endoscopic pancreatic function testing enzyme measurements?
  • In which subset of patients does secretin administration add diagnostic value for visualizing pancreatic ductal anatomy versus those where baseline imaging is sufficient?
  • What are the optimal non-invasive methods for validating exocrine pancreatic function testing on a broader scale?
  • How can we better predict which patients with chronic pancreatitis will benefit from surgical intervention versus multidisciplinary pain management?

From Invasive to Non-Invasive: The Evolution of Pancreatic Function Testing

Direct pancreatic function testing measures secretory capacity at the source. The drilling method—the original standard—used a double-lumen tube with one lumen suctioning gastric fluid and the other positioned directly in front of the ampulla to collect duodenal fluid 1:35. Bicarbonate concentration in these samples distinguished chronic pancreatitis from normal function 1:48. But the drilling method required awake patients, two tube placements, and interventional radiology support 2:39.

Endoscopic collection replaced drilling by the late 1990s. One of the discussants and colleagues at Tyler Stevens demonstrated that endoscopic pancreatic function testing produced comparable results to the drilling method 2:13. The protocol administers secretin at 0.2 micrograms per kilogram or CCK at 0.04 micrograms per kilogram at time zero, then collects duodenal aspirates every five minutes for three collections using an ERCP tapered catheter 3:05 3:23. The lab measures activities for four enzymes: trypsin, amylase, lipase, and chemotrypsin 3:48. This became the standard because it eliminated the patient burden of the drilling method while maintaining diagnostic accuracy 2:07 2:39.

MR-based quantitation may eliminate endoscopy entirely. Andrew Trout described the development of MR pancreatic function testing at Cincinnati Children's, which acquires identical imaging both before and after secretin administration 5:18. The protocol allows approximately 15 minutes between pre- and post-secretin imaging for fluid to accumulate 6:27. The sequences can be thresholded to quantify secreted fluid volume by subtracting pre-secretin from post-secretin measurements 7:38. Accurate fluid quantitation has been validated using phantoms in the MR scanner 8:13. Preliminary data in about 35 patients is examining correlation between endoscopic and MR-based assessment 8:28. The progression moves from drilling to endoscopic to completely noninvasive approaches using only IV secretin and MRI-based fluid measurement 2:07 2:13 5:18.

Timing matters when interpreting function tests. Pancreatic function can appear abnormal if checked around an acute attack 4:25. In children, there is a maturation process of pancreatic function over the first 2 to 3 years of life that must be considered when interpreting results 4:33. Qualitative assessment of exocrine function appears different between pediatric and adult patients, suggesting possible size or weight dependency 8:49.

What Doesn't Prevent Recurrent Episodes

The interventions clinicians commonly prescribe have never been shown to prevent recurrence. Multiple trials have examined whether low-fat diet, pancreatic enzyme replacement therapy (PERT), antioxidants, or steroids can prevent recurrent pancreatitis episodes or pancreatic pain episodes—none have demonstrated this benefit 12:05. PERT may improve bloating and other GI symptoms in patients with pancreatic exocrine insufficiency 12:22, and a low-fat diet is a healthier diet that may help with symptoms 12:27, but neither prevents the disease process itself 12:05 12:22 12:27.

Pain Management as Mandatory Multidisciplinary Care

Effective pain management requires three disciplines working in parallel. The pain consult comprises a pain physician for medical assessment and medication or interventional management, a psychologist for psychosocial assessment and cognitive behavioral therapy, and nurses for coordination 15:00. Psychology involvement is not optional—it occurs 100% of the time 15:24. Cognitive behavioral therapy is the standard, state-of-the-art therapy for pain management 18:16.

Frame psychology as treating the whole person, not as a referral for when nothing is wrong. Goldschneider described teaching patients the neurobiology of pain using accessible examples: the difference in how much a paper cut hurts when opening something positive versus something negative illustrates how emotions and thoughts interact with pain beyond just tissue damage 15:00. The goal is to establish that pain is an experience involving emotions and thoughts, not just tissue damage. Goldschneider emphasized the importance of framing psychology appropriately rather than as dismissal when other treatments have failed 15:00.

When opioids are appropriate, implement comprehensive safeguards. Opioids should be viewed like any other medication or procedure—as a tool to do a job, using the right tool for the right patient 20:40. In Ohio, informed consent is required for the use of opioids for chronic purposes in minors, a law implemented about a year ago 21:28. A controlled substance agreement laying out rules and expectations is important for establishing understanding between physician and patient, though not medically-legally worth very much 21:39. The emphasis throughout is on opioids as one component of multimodal care, not as monotherapy or a first-line approach.

Takeaways from this story

  • Endoscopic pancreatic function testing replaced drilling by collecting duodenal fluid after secretin stimulation—same accuracy, less burden.
  • MR-based quantitation may eliminate endoscopy by measuring secreted fluid volume non-invasively after IV secretin administration.
  • Low-fat diet, PERT, antioxidants, and steroids have never been shown to prevent recurrent pancreatitis or pain episodes in trials.
  • Psychology is mandatory in pain management—100% involvement, not optional—using cognitive behavioral therapy as the standard approach.
  • Teach pain neurobiology using accessible examples (paper cut context) to frame psychology as treating the whole person, not as dismissal.
