Using our own developed stent in the palliative treatment of obstruction in the left half of the colon due to ovarian cancer

Abstract

Objectives: An assessment of implantation efficacy and safety of self-developed self-expanding stent in patients with an ovarian cancer induced by intestinal obstruction. Material and methods:The study of the stenting efficacy and safety was realized prospectively. The group consisted of 13 patients with left half colon obstruction due to an inoperable metastatic ovarian carcinoma. All the patients had a histopathologically diagnosed ovarian carcinoma and were treated in the past both surgically and systemically. Stenting was preceded by a Computed Tomography (CT) scan confirming and locating the obstruction. Patients with a multilevel intestinal obstruction were disqualified.Results: Nine stents were implanted in the rectosigmoid; 4 stents were implanted in an externally compressed rectum. One migration of implanted stent was observed. In one case 2 stents were implanted due to an insufficient coverage of the stricture. The decompression of the obstruction of the gastrointestinal tract was achieved in 11 patients (85%). Conclusions:1) The implantation of our own developed, self-expanding stent is effective and safe.2) The implantation of the stent in patients with an inoperable ovarian cancer causing an obstruction of the gastrointestinal tract is an effective procedure limiting postoperative complications and improving life comfort by avoiding stoma.

Non-Surgical Management of Malignant Bowel Obstruction in Advanced Ovarian Cancer patients: A Systematic Review and Meta-Analysis

“…This left 24 relevant articles. 11 - 34 Only 9 of the 24 articles had sufficient statistical data (either standard error or 95% confidence intervals for the median OS, or the raw data itself) to facilitate inclusion in the meta-analysis. These results are presented in Figure 1 —PRISMA flow diagram.…”

Successful resection of colonic metastasis of lung cancer after colonic stent placement: A case report and review of the literature

“…On the other hand, the possibility of migration, perforation, and bleeding during a long-term placement of SEMS should be considered. The incidence of SEMS migration has been reported to be 5.6%-7.7% in cases of colonic stenosis caused by non-colonic malignancy with peritoneal carcinomatosis[ 55 , 56 ]. The incidence of perforation related to SEMS is reported to be 4.3%-8.3% in primary colorectal cancer[ 50 , 51 , 54 , 57 ].…”
