ObjectiveThe study aimed to review the treatment and prognosis of acute obstruction of colorectal cancers and to compare different treatment strategies of those cancers, and to evaluate the risk factors affecting perioperative complications.MethodsClinical data of 184 patients with acute obstruction of colorectal cancer undergone operation were analyzed retrospectively.ResultsA total of 184 patients with acute obstruction of colorectal cancer was collected in this study, including 58 patients with proximal and 126 patients of distal colorectal cancers. Perioperative death occurred in 2/58 patients (3.4%) with distal colorectal cancer and 6/126 cases (4.8%) of distal colorectal cancer (P > 0.05). The overall perioperative complications in the two groups were not significantly different (P = 0.794). Among the 58 patients with proximal colorectal cancer, one patient underwent colostomy, but among the 126 patients with distal colorectal cancer, 41 patients underwent colostomy, showing a significant difference between the two groups (P = 0.002). ASA scores (grade 3 - 4), elderly age (≥ 70 years) and colon perforation peritonitis were independent prognostic factors associated with perioperative mortality and morbidity. Patients in the self-expandable metallic stent (SEMS) group had a significantly shorter hospital stay (25.4 ± 8.3) d than that in the emergency surgery group (32.8 ± 16.4) d, (P = 0.039).ConclusionsEndoscopic stent implantation provides an acceptable modality of palliation for acute proximal large bowel obstruction caused by malignancies. In acute colorectal cancer obstruction, SEMS can provide a minimally invasive management compared with surgical intervention.
