Background: Randomized trials have demonstrated the superiority of surgery over endoscopy in patients with symptomatic chronic pancreatitis. However, large international studies quantifying the impact of surgery on chronic pancreatitis are lacking. The aim of this study was to evaluate current practice across Europe regarding indications, surgical techniques, and outcomes of surgery for chronic pancreatitis.
Methods: A prospective multicentre study of consecutive patients undergoing surgery for symptomatic chronic pancreatitis from 22 centres in 13 countries from 1 June 2021 to 30 November 2022 was conducted. The outcome of interest in patients with pain as an indication was the Izbicki pain score at 6-month follow-up, with complete pain relief defined as an Izbicki pain score ≤10 and partial pain relief defined as an Izbicki pain score >10, but with a >50% decrease compared with the baseline score. Quality of life was assessed using Pancreatitis Quality of Life Instrument (PANQOLI) and 12-Item Short-Form (SF-12) surveys. Predictors of pain relief were analysed using multivariable analysis.
Results: Overall, 207 patients underwent surgery (24.6% underwent surgical drainage procedures, 29.5% underwent duodenum-preserving head resections, and 45.9% underwent formal pancreatic resections). Before surgery, 48.8% used opioids and 51.2% had undergone prior endoscopic treatment. Major morbidity occurred in 14.0% and the 90-day mortality rate was 1.4%. Among 113 patients operated on for pain, the median Izbicki pain score decreased from 61.3 to 19.0 at 6 months (P < 0.001). Pain relief was achieved in 72.6% (43 patients reported complete pain relief and 39 patients reported partial pain relief). PANQOLI and SF-12 Physical Component Summary scores improved significantly (P < 0.001). Longer symptom duration (OR 0.95 (95% c.i. 0.90 to 1.00), P = 0.045) and use of opioids before surgery (OR 3.16 (95% c.i. 1.04 to 9.64), P = 0.043) predicted less pain relief.
Conclusion: Surgery for chronic pancreatitis across Europe was performed with low morbidity. Patients reported good pain relief and improvements in quality-of-life scores. Multidisciplinary consultation is recommended for all patients with chronic pancreatitis before undergoing any intervention.
