Remission & chronicity

Spontaneous remission

Progressive exocrine and endocrine insufficiency; spontaneous improvement possible in alcoholic CP with sustained abstinence (30-40% pain improvement); structural damage (fibrosis, calcifications) is irreversible

Best-intervention remission

Abstinence from alcohol in alcoholic CP: 30-40% pain improvement; endoscopic drainage of ductal obstruction: pain relief in 65-70% at 5 years; total pancreatectomy with islet autotransplantation (TPIAT): 85-90% narcotic independence at 3 years in refractory cases; antioxidant therapy: modest evidence

Drug-free remission

Chronicity

Gap size

Large — endoscopic therapy and surgery are underused in eligible patients; most are managed with analgesics indefinitely

Primary barrier

practice/access

Barrier detail: Pain management in CP often escalates to opioids without adequate trial of endoscopic decompression or TPIAT in eligible patients; TPIAT (total pancreatectomy + islet autotransplantation) for refractory pain is highly effective but available at only ~20 centres in the US; delayed referral is the dominant gap

Last SoC change: 2018 — AGA/ACG chronic pancreatitis guidelines updated; endoscopic therapy (ESWL + endoscopy) vs surgery (ESCAPE trial 2020) — surgery superior at 5 years for painful CP with duct dilatation; no major pharmacotherapy change in decades
