BACKGROUND/AIMS: To check the feasibility and safety of endoscopic stent introduction in colorectal cancer therapy.
A total of 62 patients with inoperable tumors of the rectum and rectosigmoid were treated by introducing stents. Stents were also introduced in 3 patients with advanced prostate tumors obturating (narrowing) the rectum. In 3 cases, the stents were introduced under X-ray control. In all other cases, an endoscopic approach to the stent introduction was employed.
Stents could not be introduced in 4 patients. In 1 case, the bowel was perforated above the malignant (tumorous) stenosis. In 4 patients, it was necessary to remove the stents because of dislocation. Growth of the tumor into the stent was not experienced. Experience with acute obstruction treatment was minimal as only two patients were treated for this indication.
Endoscopic stent introduction is a safe palliative procedure making it possible to improve the quality of life of patients with inoperable tumors of the rectum and rectosigmoid.
背景/目的：检验内镜下置入支架在结直肠癌治疗中的可行性和安全性。
共有62例直肠及直肠乙状结肠无法手术切除肿瘤的患者接受了支架置入治疗。另外3例晚期前列腺肿瘤导致直肠梗阻（狭窄）的患者也接受了支架置入。3例在X线引导下置入支架。其他所有病例均采用内镜下置入支架的方法。
4例患者无法置入支架。1例患者在恶性（肿瘤性）狭窄上方肠管穿孔。4例患者因支架移位而需要取出支架。未出现肿瘤长入支架的情况。由于仅2例患者因急性梗阻接受治疗，因此对急性梗阻治疗的经验很少。
内镜下置入支架是一种安全的姑息性治疗方法，可提高直肠及直肠乙状结肠无法手术切除肿瘤患者的生活质量。
