Surgical Trends in Chronic Pancreatitis from 2014 Through 2021.

Objectives: We analyzed annual surgical trends for benign chronic pancreatitis (CP), studying specifically mortality, morbidity, and pancreatic fistula rates. We also aimed to identify predictors of pancreatic fistula formation.

Methods: For this analysis, we used data from the American College of Surgeons National Surgical Quality Improvement Program from 2014 through 2021. The study included patients who underwent surgery for benign CP. Data collected included patient demographics, preoperative variables, and postoperative outcomes. Data were analyzed with univariate and multivariate analyses, with significance defined as P ≤ .05.

Results: Over the study period, the number of pancreatic surgical procedures increased 49.3%, although surgery specifically for CP declined by 31.7%. The rate of pancreatic fistula formation decreased 44.9%, and mortality decreased 31.9%. Significant predictors of a pancreatic fistula included no diabetes, preoperative sepsis, soft texture of the pancreatic gland, and greater patient weight.

Conclusion: Surgery for benign CP decreased substantially despite the established efficacy of surgical intervention for long-term pain management. The concurrent decline in mortality and rates of pancreatic fistula formation suggest advances over the study years in surgical and postoperative care.
