The aim of this study is to compare the stoma rate, clinical efficacy, and safety of patients treated by endoscopic stenting followed by elective laparoscopic resection (the 'endolaparoscopic approach') versus immediate emergency surgery for obstructing left-sided colorectal cancers.

Primary Outcome Measures:
  • The success rate of relieving obstruction after stent insertion
  • The stoma rate in the two groups of patients

Secondary Outcome Measures:
  • Morbidity and mortality rates in the two groups
  • Hospital stay

Estimated Enrollment: 70
Study Start Date: January 2000
Detailed Description:
In patients who present with obstructing left-sided colorectal cancers, emergency surgery carries a significant morbidity and mortality. Traditionally, most of these patients would receive staged operations (Hartmann's procedure). Temporary stoma is often required due to the edematous bowel wall precluding primary anastomosis as a result of obstruction and the poor pre-morbid status. A second operation is subsequently required to restore bowel continuity. Apart from the expensive hospital costs of the staged operations, the patient's acceptance to the stoma is poor and the social inconvenience associated with the stoma is obvious. Thus, a significant portion of patients would not be suitable for the second operation due to poor health or advanced disease and having to bear the stoma for the remainder of life. Recently, self-expandable metal stents have been used with success in relieving the acute obstruction in patients with obstructing left-sided colorectal cancers. Endoscopic stenting may help to relieve the obstruction, avoid emergency surgery, and allows patients to undergo one-stage elective surgery without the necessity of making a stoma. We propose to evaluate the clinical benefits of using self-expandable metal stents in patients with obstructing left-sided colorectal cancers followed by elective laparoscopic resection and compare its use to immediate emergency surgery.
