Abstract

Background Small bowel obstruction (SBO) after colectomy leads to markedly lower patient quality of life, longer hospital stays, and increased hospitalization costs. From a systemic treatment point of view, early postoperative SBO is one of the major concerns of the surgery because it often delays chemotherapy in advanced cases. The goal of this single-center study was to evaluate the risk factors for early postoperative SBO. Methods Univariate and multivariate analyses were performed for 1,004 patients who underwent open colectomy (OC, 421 patients) or laparoscopic-assisted colectomy (LAC, 583 patients) for colorectal cancer between January 1997 and December 2008. Results The overall early postoperative SBO were 45 cases (4.5%). Univariate analysis of the risk factors for early postoperative SBO showed no statistical significance between respective risk factors and occurrence of SBO for age >70 years, body mass index >25 kg/m2, ASA score ≥3, pT stage T4, pN stage ≥N1, pM stage M1, or increased blood loss. Multivariate analysis demonstrated that OC (odds ratio (OR), 2.62; 95% confidence interval (CI), 1.34- 5.13; P = 0.005), and rectal cancer (OR, 2.12; 95% CI, 1.1-4.1; P = 0.025) were independent risk factors for postoperative SBO after colectomy for colorectal cancer. Regarding the causes of SBO, paralytic obstruction was more frequent in the LAC group, and adhesive obstruction was more frequent in the OC group. Conclusions Early postoperative SBO cases are more likely to occur with OC and rectal cancer. LAC is an effective surgical procedure from the perspective of reducing the incidence of early postoperative SBO after colectomy for colorectal cancer.
