Secondary outcome
Costs of both strategies.
Background summary
Objective: To compare colonic stenting followed by surgery with emergency surgery for the management of acute left-sided malignant colonic obstruction in terms of health-related quality of life, morbidity and mortality.
Study design: Prospective randomized multicenter trial.
Study population: Patients with acute left-sided malignant colonic obstruction.
Intervention: Patients will be randomized to either emergency surgery (current standard treatment) or colonic stenting as bridge to elective surgery.
Outcome measurements: Effectiveness and costs of both strategies. Effectiveness will be evaluated in terms of quality of life, morbidity and mortality. Quality of life will be measured with standardized questionnaires (EORTC QLQ-C30, EORTC QLQ-CR38 and EuroQol). Morbidity is defined as every event leading to hospital admission or prolonging hospital stay. Mortality will be analyzed as total mortality as well as procedure-related mortality.
Power/data analysis: Including 120 patients on a 1:1 basis will have 80% power to detect an effect size of 0.5 on the EORTC QLQ-C30 global health scale, using a two group t-test with a 0.05 two-sided significance level. Differences in quality of life and morbidity will be analyzed using mixed-models repeated measures analysis of variance. Mortality will be compared using Kaplan-Meier curves and log-rank statistics.
Economic evaluation: The total costs of treatment will be evaluated by counting volumes and calculating unit prices.
Time schedule: Patient inclusion from January 2007 until the 31st of December 2009. Interim analysis will be done after inclusion of 60 patients. Final analysis and reporting April/October 2010.
Study objective
Which treatment strategy is the most effective for patients with acute left-sided malignant colonic obstruction: either colonic stenting followed by elective surgery or emergency surgery.
Intervention
Patients will be randomized to either emergency surgery (current standard treatment) or colonic stenting as bridge to elective surgery.
