RESUMO
The aim of this study is to describe the current utilization of artificial nutrition [enteral (EN) or total parenteral (TPN)] for pancreatic fistula (POPF) after pancreatoduodenectomy (PD). Prospective data of 311 patients who consecutively underwent PD at a tertiary referral center for pancreatic surgery were collected. Data included the use of EN or TPN specifically for POPF treatment, including timing, outcomes, and adverse events related to their administration. POPF occurred in 66 (21%) patients and 52 (79%) of them were treated with artificial nutrition, for a median of 36 days. Forty (76%) patients were treated with a combination of TPN and EN. The median day of artificial nutrition start was postoperative day 7, with a median drain output of 180 cc/24 h. In 33 (63%) patients, artificial nutrition was started while only a biochemical leak was ongoing. Fungal infections and catheter-related bloodstream infection occurred in 13 (28%) and 15 (33%) TPN patients, respectively; among EN patients, 19 (41%) experienced diarrhea not responsive to pancreatic enzymes and 9 (20%) needed multiple endoscopic naso-jejunal tube positioning. The majority of the patients developing POPF after PD were treated with a combination of TPN and EN, with a clinically relevant rate of adverse events related to their administration. Standardization of nutrition routes in patients developing POPF is urgently needed.
