Abstract

The prevalence of acute colorectal obstruction at the hospital setting is high. There is need for improvement in the quality of colonoscopy for relieving obstruction. A retrospective, uncontrolled, open‑label study was conducted, with the aim of documenting the causes of acute colorectal obstruction and the quality of colonoscopy practice in managing obstruction at a university hospital in China. A total of 61 adult patients with acute colorectal obstruction treated with urgent colonoscopy between February, 2011 and January, 2016 were identified at the Endoscopic Unit of Tongji Hospital (Wuhan, China). The technique success rate was the primary outcome. The etiology was mainly related to malignant diseases, including colorectal cancer in 53 patients (86.9%) and advanced peritoneal serous carcinoma leading to extrinsic colonic compression in 1 patient (1.6%). Benign causes of obstruction included foreign bodies in 3 patients (4.9%) and fecal impaction in 2 patients (3.3%); furthermore, anastomotic strictures were found in 2 patients (3.3%). The technique success rate was 98.4% (60/61). All colorectal cancer patients who underwent urgent colonoscopy were admitted to the Department of Surgery for placement of a self‑expanding metallic stent; 1 patient who had an extracolonic malignancy underwent placement of a transanal colonoscopic decompression tube as palliative therapy and 2 patients with anastomotic strictures underwent endoscopic balloon dilation. Furthermore, colonoscopy was used for extracting the foreign body, as well as removing fecal stones in all the patients. In conclusion, urgent colonoscopy as a minimal invasive approach is associated with certain advantages for diagnosing and managing acute colorectal obstruction. Furthermore, experienced operators achieved a better outcome when managing colorectal obstruction.
