Endoscopic stenting for malignant tumors in the area of the bauginium fl ap

Abstract

Introduction. Stenting in the ileocecal region is not a routine procedure. Proximal colonic obstruction is generally managed with primary surgery, although there are no RCTs to support this assumption. Recent reports have shown that emergency right colon resection can be associated with high morbidity and mortality rates. We report about 8 cases of obstructive ileocecal cancer for palliative treatment. Case report. Four men and 4 women (mean age, 69 years; range, 62–82 years) were stenting for obstructive ileocecal cancer between September 2014 and December 2019. Emergency SEMS placement was attempted in the remaining 5 cases. An uncovered colonic stent (S&G Biotech; Boston Scientifi c) 22, 24, 25 mm in diameter, 6, 8or 9cm in length, was used. Clinical success is achieved in all cases. One patient was diagnosed with stent migration 4 weeks after stenting, and repeated stenting was performed. Five patients received chemotherapy after stenting, two patients refused further treatment. Discussion. Placing SEMS for ileocecal obstruction is technically challenging for the following reasons. The long distance from the anus, tortuosity of the bowel and angled anatomy of stricture make an ileocecal lesion difficult to reach endoscopically. SEMS can be an alternative to emergency surgery for obstruction due to right colon cancer. In our study, we had migration in 1 case, no perforations or stent ingrown were detected. Conclusion. Stenting for malignant tumors of the ileocecal region, complicated by intestinal obstruction is an eff ective and safe minimally invasive intervention, and can be used as an alternative to emergency surgery.
