The Comparison Of Between The Painless And The Common Endoscopic Techniques For The Treatment Of The Esophageal Probe Dilation And Stent Placement In Esophagostenosis

【OBJECTIVE】To evaluate the clinical efficacy, safety and comfort of the painless endoscopic technique for the treatment of the esophageal probe dilation and stent placement in esophagostenosis.【METHODS】165 cases patients of esophagostenosis who were treated were studied retrospectively at the department of endoscopy of the Affiliated Tumor Hospital of Guangxi Medical University from November,2003 to June,2009. They were divided into group A and group B. Group A was the esophageal probe dilatation, which 45 cases were treated with the propofol combined with fentanyl intravenous anesthesia (ie,the painless group) and 38 cases were treated in the state of awake (ie,the control group).Group B was the stent placement, which 42 cases were treated with the propofol combined with fentanyl intravenous anesthesia (ie,the painless group) and 40 cases were treated in the state of awake (ie,the control group).The changes of Mean arterial pressure (MAP), pulse oxygen saturation(SpO2),heart rate(HR) the discomfort reactions, complications, the success rate, the total efficiency were observed in total patients with preoperative, operation and after treatment.【RESULTS】Group A:the changes of MAP, SpO2 and HR of before and after expansion were no significant difference (P>0.05) between the painless group and the control group.The changes of MAP,SpO2 and HR of expansion were significant difference(P<0.05) between groups, MAP, HR of the control group increased and SpO2 of the control group decreased significantly compared with the painless group during expansion. The complications and the success rate of expansion were no significant difference(P>0.05) between groups. The uncomfortable reaction and the total effective rate of expansion were significant difference during expansion(P<0.05)between groups,which the painless group was superior to the control group.Group B:the changes of MAP, SpO2 and HR of before and after stent placement were no significant difference (P>0.05) between the painless group and the control group.The changes of MAP,SpO2.and HR of stent placement were significant difference(P<0.05) between groups, MAP, HR of the control group increased and SpO2 of the control group decreased significantly compared with the painless group during stent placement. The complications, the success rate and the total effective rate of stenting were no significant difference(P>0.05) between groups. The uncomfortable reaction of stent placement were significant difference during placment(P<0.05)between groups,which the painless group was superior to the control group. In between group A and group B, the massive hemorrhage and the esophageal perforation did not occur; the obstruction of the successful treatment patients was basically relieved and their dysphagia symptoms were obviously improved.【CONCLUSIONS】The painless endoscopic technique for the treatment of the esophageal probe dilation and stent placement in esophagostenosis is an effective, safe and reliable method,which is no significant pain and serious complications and have the greater clinical value.Patients are willing to accept it.
