[Cases of Oncologic Emergency Associated with Colorectal Cancer].

The clinical condition of oncologic emergency associated with colorectal cancer includes hemorrhage, perforation and obstruction. Obstructive colorectal cancer is an oncologic emergency commonly observed in our daily clinical practice. Colonic stent placement for obstructive colorectal cancer is relatively easy and safe and may be considered as an effective treatment method that enables favorable intestinal decompression preoperatively and one-stage resection. Colonic stent use can be a bridge to surgery, enabling shorter duration of hospitalization, and reduced postoperative complications, and colostomy rates, as compared to emergency surgery. From January 2009 to December 2016, this study was designed to evaluate the clinical outcomes of 68 patients who underwent surgery for obstructive colorectal cancer. The patients were divided into 2 groups: 32 cases receiving colonic stent placement(the S group), 36 cases receiving ileus tube and emergency surgery(the NS group). There was no significant difference in terms of morbidity or survival rate between the 2 groups. For the S group, 31 out of 32 could one-stage resection(94%). The colostomy rate in the S group was significantly lower than that in the NS group(3% vs 33%). In the S group, number of dissected lymph nodes was significantly larger and the duration of postoperative stay was shorter than that in the NS Group.
