The guideline strongly recommends early oral feeding and enteral rather than parenteral nutrition for all patients with acute pancreatitis. In 11 randomized controlled trials, early and delayed feeding led to similar rates of mortality, but delayed feeding produced a 2.5-fold higher risk of necrosis (95% CI for OR, 1.4-4.4) and tended to increase the risk of infected peripancreatic necrosis, multiorgan failure, and total necrotizing pancreatitis, the authors wrote. In another 12 trials, enteral nutrition significantly reduced the risk of infected peripancreatic necrosis, single-organ failure, and multiorgan failure compared with parenteral nutrition.
Clinicians continue to debate cholecystectomy timing in patients with biliary or gallstone pancreatitis. The guidelines strongly recommend same-admission cholecystectomy, citing a randomized controlled trial in which this approach markedly reduced the combined risk of mortality and gallstone-related complications (OR, 0.2, 95% CI, 0.1-0.6), readmission for recurrent pancreatitis (OR, 0.3, 95% CI, 0.1-0.9), and pancreaticobiliary complications (OR, 0.2, 95% CI, 0.1-0.6). “The AGA issued a strong recommendation due to the quality of available evidence and the high likelihood of benefit from early versus delayed cholecystectomy in this patient population,” the experts stated.
Patients with biliary pancreatitis should be evaluated for cholecystectomy during the same admission, while those with alcohol-induced pancreatitis should receive a brief alcohol intervention, according to the guidelines, which also call for better studies of how alcohol and tobacco cessation measures affect risk of recurrent acute pancreatitis, chronic pancreatitis, and pancreatic cancer, as well as quality of life, health care utilization, and mortality.
The authors also noted knowledge gaps concerning the relative benefits of risk stratification tools, the use of prophylactic antibiotics in patients with severe acute pancreatitis or necrotizing pancreatitis, and the timing of ERCP in patients with severe biliary pancreatitis with persistent biliary obstruction.
