Laparoscopic right hemicolectomy is the standard surgical approach for treatment of right-sided colonic neoplasms. Although performed within a strict Enhanced Recovery After Surgery (ERAS) program, patients still develop postoperative ileus. The aim of this study was to describe the factors responsible for postoperative ileus after right hemicolectomy in a patient population with over 80% ERAS adherence. In this retrospective study, we analyzed 499 consecutive patients undergoing elective right-sided colectomy for neoplastic disease in a single high-volume center. All patients followed an updated ERAS program. The overall median ERAS adherence was 80%. Patients with ≥ 80% adherence (n = 271) were included in further analysis. Their median ERAS adherence was 88.9% (interquartile range, 80-90; range, 80-100). Twenty-four of 271 patients (8.9%) developed postoperative ileus. A univariate regression analysis revealed carcinoma situated in the transverse colon, duration of operation over 200 minutes, and opiate consumption over 10 mg on the second postoperative day (POD) to be associated with a significantly higher risk of postoperative ileus. Multivariate regression analysis revealed that duration of surgery over 200 minutes (odds ratio [OR], 2.4; 95% confidence interval [CI], 1.0-5.8; P = 0.045) and opiate consumption over 10 mg on POD 2 (OR, 4.8; 95% CI, 1.6-14.3; P = 0.005) independently predict a higher risk for postoperative ileus. The median length of hospital stay was significantly longer in patients with postoperative ileus (8 days vs. 3 days, P < 0.001). None of the 271 patients died during a 30-day follow-up. Long duration of surgery, even minor postoperative opiate use, predict a higher risk for postoperative ileus in strictly ERAS-adherent patients undergoing laparoscopic right hemicolectomy.
