@entity1 with obstructing @entity5 are ineligible for preoperative chemotherapy and radiation unless they undergo surgical diversion. Endoscopic laser therapy (ELT) may provide an alternative to colostomy for these @entity1 . We retrospectively reviewed all @entity1 with distal sigmoid and @entity189 who underwent ELT from January 1988 through April 1990. The majority of @entity1 were referred for palliation of @entity1442 . Thirty-seven @entity1 underwent 123 ELT sessions (median, 2.5; range, one to 18). In 84% of @entity1 , patency was maintained during a median follow-up of 31.5 weeks (range, one to 123). Morbidity and mortality were 2.5% (3/123) and 5% (1/37), respectively. Sixty-two percent had radiotherapy, chemotherapy, and/or surgery concurrent with ELT. Endoscopic laser therapy can safely and effectively reestablish and maintain luminal patency in @entity1 with obstructing @entity5 . In addition, ELT can enable the administration of preoperative adjuvant radiotherapy and chemotherapy.

Endoscopic laser recanalization is effective for prevention and treatment of obstruction in sigmoid and XXXX .
