“…In recent years, some authors have reported favorable results for non-surgical relief of acute malignant colonic obstruction by placing an uncovered, self-expandable metallic stent (11-13, 16-19). The technical and clinical success rates of our study are comparable to other series, which varied between 80% and 100% (11-21, 24-28). The site of the lesion influences the technical success rate, with rectosigmoid lesions being easier to treat than transverse colon lesions.…”

ObjectiveWe wanted to evaluate usefulness of uncovered stent in comparison with covered stent for the palliative treatment of malignant colorectal obstruction.Materials and MethodsCovered (n = 52, type 1 and type 2) and uncovered (n = 22, type 3) stents were placed in 74 patients with malignant colorectal obstruction. Stent insertion was performed for palliative treatment in 37 patients (covered stent: n = 23 and uncovered stent: n = 14). In the palliative group, the data on the success of the procedure, the stent patency and the complications between the two groups (covered versus uncovered stents) were compared.ResultsThe technical success rate was 89% (33/37). Symptomatic improvement was achieved in 86% (18/21) of the covered stent group and in 92% (11/12) of the uncovered stent group patients. The period of follow-up ranged from three to 319 days (mean period: 116±85 days). The mean period of stent patency was 157±33 days in the covered stent group and 165±25 days in the uncovered stent group. In the covered stent group, stent migration (n = 11), stent fracture (n = 2) and poor expansion of the stent (n = 2) were noted. In the uncovered stent group, tumor ingrowth into the stents (n = 3) was noted.ConclusionSelf-expanding metallic stents are effective for relieving malignant colorectal obstruction. The rate of complications is lower in the uncovered stent group than in the covered stent group.

“…A review by Watt et al found median complication rates of stent migration 11%, perforation 4.5%, and tumour overgrowth 12% [12]. Clinical success is usually quoted at a rate of 85–100% [1, 8, 12, 13] with mortality between 0 and 2%. This study had a primary perforation rate of 0% in line with the literature, but we had an overall mortality of 2/37 (5%) when restented patients were taken into account.…”

Aim. Self-expanding metal stents (SEMSs) are increasingly used for the palliation of metastatic colorectal cancer and as a bridge to surgery for obstructing tumours. This case series analyses the learning curve and changes in practice of colorectal stenting over a three year period. Methods. A study of 40 patients who underwent placement of SEMS for the management of colorectal cancer. Patients spanned the learning curve of a single surgeon endoscopist. Results. Technical success rates increased from 82% initially, using an average of 1.7 stents per procedure, to a 94% success rate where all patients were stented using a single stent. There has been a change in practice from elective palliative stenting toward emergency preoperative stenting. Conclusion. There is a steep learning curve for the use of SEMS in the management of malignant colorectal bowel obstruction. We suggest that at least 20 cases are required for an operator to be considered experienced.

“…Open surgery for acute bowel obstruction due to malignant left-sided colonic tumors is associated with a high chance of stoma creation as well as increased mortality and morbidity. For these reasons, during the past two decades, these tumors have been increasingly treated with endoscopic decompression at the initial phase and then definitive laparoscopic excision (1).…”

Introduction: We previously conducted a randomized trial comparing the endo-laparoscopic approach (i.e. placing self-expanding metallic stents followed by laparoscopic resection) and conventional open surgery in the treatment of obstructing left-sided colon cancer. This study is a follow-up of the previous randomized trial and aims to report the long-term outcomes of the two groups. Methods: Forty-eight patients from the randomized trial were followed up in an outpatient clinic with regular monitoring. Patients were compared for clinicopathological variables, disease recurrence and survival rates.Results: Clinicopathological details were comparable between the two groups. During the median follow-up periods of 32 months for the open group and 65 months endo-laparoscopic group, no statistically significant difference was observed between the groups in disease recurrence rate, 5-year overall survival (27% vs 48%, P = 0.076) and 5-year disease-free survival rates (48% vs 52%, P = 0.63). Conclusion: Besides being a safe bridge to subsequent elective laparoscopic surgery, preoperative self-expanding metallic stents insertion does not adversely affect oncological outcomes and patient survival. Based on our data, the endo-laparoscopic approach is the treatment of choice for patients presenting with malignant left-sided colonic obstruction.
