We report on 36 cases where colonic stents were placed and retrospectively analyze the efficacy. Colonic stents were placed in 27 patients to perform single-stage elective surgery (Bridge to Surgery [BTS] Group), and in 9 patients to alleviate malignant colorectal obstructions (palliative treatment group). Of the 36 patients, 35 had a stent placed successfully. In the BTS group, there were no major complications associated with the placement of the stent. Patients who had elective surgery could have fluids on post-operative day 1 (median), solid food on post-operative day 3 (median), and could leave the hospital on post-operative day 13 (median). For the palliative treatment group, eight out of nine could receive a stent. One patient had complications from restenosis but was able to have food. We found that endoscopic placement of SEMS to relieve colonic obstruction can correct dehydration, electrolyte imbalance, and friable colonic mucosa due to large bowel distention. By avoiding emergency surgery, it is suggested that patients can start having food early on in the post-operative period, and can recover quickly after operation. Successful placement of SEMS not only achieved colonic decompression but also improved quality of life.
