Abstract: | BackgroundConsensus guidelines have indicated that postoperative parenteral nutrition (PN) might provide benefit when patients are expected to be nil per os (NPO) ≥7 d and when PN is administered ≥5 d. We hypothesized that most children receiving PN after appendectomy do not satisfy these criteria.MethodsThe medical records of the patients who had undergone appendectomy for perforated appendicitis from 2006–2011 were analyzed, and the proportion meeting the criteria for beneficial PN was determined. The clinical parameters independently associated with the criteria for beneficial PN (PN therapy ≥5 d, ileus ≥5 d, NPO ≥7 d) were identified using multiple regression analysis.ResultsA total of 1612 patients were treated for appendicitis. Of these, 587 met the inclusion criteria (age <16 y, perforated appendicitis, appendectomy within 24 h, no previous indication for PN). Of the 587 patients, 12.1% received PN; 43.8% of these received PN for ≥5 d. The predictors of PN duration of ≥5 d included preoperative symptoms for ≥3 d (P < 0.01) and initiation of PN by postoperative day 3 (P = 0.047). Preoperative symptoms for ≥3 d, imaging showing a discrete abscess or bowel obstruction, and operative findings of diffuse peritonitis predicted ileus of ≥5 d and NPO of ≥7 d (P < 0.01 for all). Major complications were more common in patients with ileus lasting ≥5 d.ConclusionsFewer than one-half of patients receiving PN in the present cohort met the consensus-based guidelines for postoperative PN. The preoperative symptom duration, preoperative imaging findings demonstrating abscess and/or bowel obstruction, and intraoperative findings of diffuse peritonitis might predict prolonged ileus and longer recovery periods for children undergoing surgery for perforated appendicitis. |
