“…Within the RCTs, diverse treatment modalities were administered, including NPO to 244 patients, TPN to 450 patients, NJ feeding to 590 patients, NG feeding to 209 patients, and oral feeding to 101 patients. Notably, 18 trials specifically addressed SAP [17, 19–21, 23, 24, 22, 32–34, 36, 38, 44, 45, 47, 48, 50, 52], 6 RCTs focused on non‐severe pancreatitis [41, 42, 46, 49, 51, 53], whereas the severity classification remained unspecified in the remaining three trials [35, 40, 54]. Initiating nutritional support within 24 h was practiced in 10 of the 27 RCTs, whereas 6 studies commenced nutritional intervention within 48 h. Additionally, nine trials did not restricte initiation of nutritional support within 48 h, and two did not specify the exact timing of nutritional intervention.…”
