Abstract: Objective To investigate the application and clinical effect of endoscopic assisted placement of decompression tube in acute obstructive induced by colorectal carcinoma. Methods Thirteen patients with colorectal cancer complicated with acute obstruction treated with decompression tube and 3~7 days later, all the patients underwent colorectal cancer radical surgery. Results All the 13 patients were successfully placed in the decompression tube; and abdominal pain and abdominal distension were relieved, the symptoms of bloating and vomiting disappeared. Three days later, the abdominal circumference was reduced from （92.7±5.7） to （81.2±4.8） cm （P<0.001）. The intra-abdominal pressure was reduced from （21.00±1.5） to （12.2±0.8） cmH₂O （P<0.001）; the drainage volume of the decompression catheter decreased from （782.3±72.1） to （33.8±15.3） ml （P<0.001）; the maximum transverse diameter of the proximal intestinal tube was reduced from （5.4±0.6） to （2±0.3） cm （P<0.001）. All cases underwent one-stage radical surgery, and there were no postoperative complications such as anastomotic leakage and wound infection occurred. Conclusion Colorectal cancer with acute intestinal obstruction, Endoscopic assisted placement of decompression tube in the colorectal cancer with acute intestinal obstruction can not only relieve the symptoms of intestinal obstruction, but also improve the general condition of the patient and fully complete the preoperative preparation, and win the opportunity for radical surgery. The advantages of safety, economy, and trauma may benefit greatly for these patients.
