Clinical value of endoscopic metal stent placement for malignant colonic obstruction in aged people / 中华老年医学杂志

ABSTRACT

Objective To evaluate the clinica1 value of endoscopic placement of colorectal metal stents for malignant colonic obstruction in aged patients. Methods The 82 cases who were older than 65 years with malignant colonic obstruction were randomly divided into colorectal metal stenting group who were treated with endoscopic Niti-S colorectal metal stenting and emergency surgery group who were treated with tumor resection or colostomy. The average length of stay, average hospitalization charge, median survival time, one-year survival rate, perioperative mortality, and the complications such as anastomotic leakage, incision infection were analyzed. Results In colorectal metal stenting group, in 39 of 41 patients, metal stents were successfully inserted, without complications of hemorrhage, perforation and so on. And the symptoms of obstruction were effectively relieved within 2 days. The 17 cases underwent subsequent elective radical resection of colorectal carcinoma after 1 week, without complications of anastomotic leakage. The 22 cases were treated with colorectal metal stenting for palliative treatment. There were 4 cases of stent migration and 5 cases of stent obstruction again. The average length of inhospital stay was (17.9±6.7) days, the average hospitalization charge was 40 047 yuan, the median survival time was (9.4±4.4) months, and one-year survival rate was 43.9%. In emergency surgery group, 13 cases underwent tumor resection and 28 cases received colostomy. The 14 cases presented with multiple organ dysfunction, 8 cases died preoperatively, 4 cases presented with anastigmatic leakage. The average length of stay was (24.4±4.6) day, the average hospitalization charge was 61 867 yuan, the median survival time was (8.8±4.8) months, and one-year survival rate was 36.6%. Conclusions Endoscopic colorectal metal stenting is a safe, economic and effective treatment for malignant colonic obstruction in aged patients, especially reduces the risk of surgical complications, improves the aged patient's quality of life.
