Letter to the Editor: Frey procedure outcomes in chronic pancreatitis: A commentary

Abstract

The Frey procedure (pancreatic head coring with longitudinal duct drainage) provides sustained pain control for selected patients with chronic pancreatitis. The single-center cohort by Eppa et al., published in the recent issue of the Euroasian J Hepatogastroenterol discussed in this letter, long-term follow up showed marked and durable reductions in validated pain scores and improvements in health-related quality of life measures. However, exocrine and endocrine insufficiency continued to progress despite surgery, underscoring that symptom control does not necessarily modify disease evolution. These findings support timely referral for surgical evaluation in patients with refractory symptoms and reinforce the need for structured long-term metabolic and nutritional follow-up after surgery.

Core Tip: The Frey procedure provides durable pain relief in chronic pancreatitis by combining pancreatic head resection with ductal drainage. A recently published study reports significant improvements in pain and quality of life, while noting ongoing progression of exocrine and endocrine insufficiency. This letter highlights the clinical relevance of these findings and emphasizes the importance of long-term metabolic and nutritional follow-up.

TO THE EDITOR

I read Eppa et al[1], recently published in the recent issue of the Euroasian J Hepatogastroenterol single center analysis evaluating long term outcomes following the Frey procedure in patients with chronic pancreatitis. The authors present valuable data demonstrating substantial improvements in pain control and quality of life, reinforcing the role of surgery as an effective therapeutic strategy for carefully selected patients. The most striking result in the study is the significant and sustained reduction in pain as measured by the validated Izbicki scoring system, with postoperative scores remaining markedly lower over five years of follow up[1]. This reinforces the concept that combined pancreatic duct drainage and targeted resection of the inflamed pancreatic head interrupt key pathophysiological drivers of pain. Previous long-term evaluations have demonstrated similar benefits[2,3]. The improvement in physical and mental quality-of-life domains further supports the broader benefit of surgical intervention[1]. Patients with chronic pancreatitis frequently experience nutritional, social, and psychological burdens, and meaningful pain relief leads to improved functional independence. Published literature consistently reports improved quality of life after the Frey procedure[4]. Despite effective pain relief, the persistence or progression of exocrine and endocrine pancreatic insufficiency is notable[1]. New onset diabetes mellitus and ongoing steatorrhea reflect the fibrotic evolution of chronic pancreatitis, which surgery cannot halt. Thus, postoperative care must include metabolic and nutritional monitoring. The study also informs the ongoing comparison between endoscopic and surgical therapy. Many patients previously underwent pancreatic duct stenting with limited improvement, whereas surgery achieved substantial symptomatic relief[1]. This aligns with randomized evidence demonstrating superior long-term outcomes for surgery compared to endoscopic drainage[5]. In summary, the authors add important contemporary evidence supporting the Frey procedure as an effective option for chronic pancreatitis. Their findings reinforce the need for timely surgical referral and structured long-term follow-up to address nutritional and metabolic consequences.
