Using the E-PASS scoring system to estimate the risk of emergency abdominal surgery in patients with acute gastrointestinal disease

Abstract

The Estimation of Physiologic Ability and Surgical Stress (E-PASS) scoring system, which quantifies a patient's reserve and surgical stress, is used to predict morbidity and mortality in patients before elective gastrointestinal surgery. We conducted this study to clarify whether the E-PASS scoring system is useful for assessing the risks of emergency abdominal surgery. The subjects of this retrospective study were 51 patients who underwent emergency gastrointestinal surgery at a public general hospital. The main outcomes were the E-PASS scores and the postoperative course, defined by mortality and morbidity. Postoperative complications developed in 15 of the 51 patients (29.4%). The E-PASS score was significantly higher in the patients with postoperative complications than in those without (0.61 ± 0.31 vs 0.20 ± 0.35, respectively; n = 36). The morbidity rates were significantly lower in the patients with a value less than 0.5 than in those with a value more than 0.5 (17.1% and 56.3%, respectively; P < 0.01). There were 7 operative deaths among the 16 patients with a high score, versus none among the 9 patients with a low score (P < 0.01). Three patients underwent laparoscopic-assisted bowel resection with a good postoperative course, with scores of less than 0.5. The E-PASS scoring system is useful for surgical decision making and evaluating whether patients will tolerate emergency gastrointestinal surgery. Minimally invasive therapy would assist in lowering the risk of complications.
