Application Analysis of through-the-scope stent for patients with proximal malignant colonic ob-struction / 临床外科杂志

ABSTRACT

Objective To investigate the clinical values of preoperative through-the-scope(TST) stent implementation by analyzing its effectiveness and reliability in patients with acute colonic obstruction caused by proximal colonic cancer.Methods From June 2008 to June 2014,36 patients with proximal colonic cancer accompanied by acute obstruction were analyzed.Obstructive sites consisted of ileocecal junction(n =4),ascending colon(n =20),and transverse colon near the hepatic flexure(n =12).A-chievement ratio of the colonic tumor resection,the incidence rate of complications,operation time,and hospitalization were evaluated.Results TTS was successfully placed in all patients.All patients showed relief of obstructive symptoms within 1 ~2 days.Surgical resection was performed after 5 ~7 days.A total of 34 patients got a radical colonic tumor resection,while the other two patients had liver and pelvic metas-tasis.All patients were welly recovered without complications of anastomotic leakage,intraperitoneal infec-tion and bleeding.Conclusion For patients with acute colonic obstruction caused by proximal colonic cancer,preoperative through-the-scope(TST)stent implementation is a cost-effective and safe method.It reduces trauma and pain,and enhances life quality for patients,which is worthy of being spread.
