Emergency endoscopy: recanalization of intestinal obstruction caused by colorectal cancer.
Endoscopic recanalization was attempted in 17 patients with obstruction caused by colorectal cancer who were at high surgical risk on account of their poor clinical condition. Combined use was made of pneumatic and mechanical dilation, debulking with a diathermal snare, and photoablation with neodymium-yttrium-aluminum-garnet laser. Successful recanalization was obtained in 94% of cases. The only failure was in a patient with a neoplasm of the rectosigmoid junction. Elective surgery was not performed on the patients after recanalization because of the presence of severe concomitant disease or diffuse metastasis. Patients were followed for 6.25 +/- 6.17 months with 1.6 +/- 0.7 treatments within the first month to stabilize patency and then with an average of 0.88 +/- 0.63 treatments per month to maintain patency. Only 2 patients had recurrence of obstruction, and the actuarial survival was 63% at 6 months and 23% at 1 year. Endoscopic treatment has proved effective because it allows rapid recanalization with resolution of emergency and maintenance of patency in patients for whom elective surgery is not indicated. In selected cases, therefore, endoscopic recanalization is a sound alternative to emergency surgery.
