" colon stent"

Anouk E J Latenstein, Mathijs P Hendriks, Emo E van Halsema, Jeanin E van Hooft, Anne-Marie van Berkel
Self-expanding metal stents can be considered as initial treatment for malignant large bowel obstruction in the palliative setting. It is suggested that systemic anti-angiogenic therapy increases the risk of stent perforation. We report a 65-year-old woman with a metastatic, obstructing colon tumor who has been successfully treated with stent placement and chemoimmunotherapy consisting of capecitabine and bevacizumab for 8 years.

INTRODUCTION: Colonic stent insertion is widely used as a bridge to surgery(BTS)for obstructive colorectal cancer. Stenting can shorten hospitalization and decrease complication and colostomy rates in comparison with emergency surgery. We investigated patients who underwent colonic stent insertion for BTS in our hospital. PATIENTS: Sixteen patients(8 men, 8 women) with a colorectal obstruction score of 0 or 1 who underwent colonic stent insertion as a BTS between April 2015 and April 2017 period were investigated...

The patient was a 70-year-old woman who was diagnosed with obstructive transverse colon cancer suspected of invading the abdominal wall by abdominal CT imaging. Since the preoperative electrocardiogram showed an ischemic change, echocardiography and coronary angiography were performed. We diagnosed chronic heart failure and angina pectoris because echocardiography showed low cardiac function(left ventricular ejection fraction; LVEF 37%)and coronary angiography indicated triple-vessel disease. We firstly performed coronary artery bypass graft surgery following self-expanding metallic stent placement as a bridge to surgery(BTS), because we judged this patient as a perioperative high-risk case...

Stoma is a treatment option often adopted for large bowel obstruction accompanying peritoneal dissemination of gastric cancer, but the invasiveness of this intervention can be an issue for patients with limited prognosis and reduced quality of life. In our hospital, colonic stenting for bowel obstruction due to peritoneal dissemination from gastric cancer was performed for 7 consecutive patients. Oral ingestion became possible in 5 cases, and colonic stent was considered a useful treatment choice for appropriate cases...

The placement of a self-expanding metallic stent (SEMS) in obstructive colorectal cancer (OCRC) is acknowledged to be a safe and effective procedure for the relief of obstruction. However, there is concern that shear forces acting on the tumor during stent expansion may release cancer cells into the circulation, resulting in a poor prognosis. The aim of the present study was to determine whether colonic stent insertion increases viable circulating tumor cells (v-CTCs). A telomerase-specific replication-selective adenovirus-expressing GFP (TelomeScanF35) detection system was used to detect v-CTCs in 8 OCRC patients with a SEMS before and after stent insertion and after surgical resection...

We report a case of endocrine cell carcinoma of the colon with very poor prognosis, onset with bowel obstruction and multiple liver metastases. The patient was a 77-year-old man who underwent left hemicolectomy after a colon stent treatment for bowel obstruction due to cancer of the transverse colon with unresectable multiple liver metastases. Chemotherapy was not initiated because of his poor health. He died of primary cancer 52 days after the surgery. Endocrine cell carcinoma of the large intestine has a poor prognosis due to an early onset of liver and lymph node metastases, as well as peritoneal dissemination...

We present the case of a 93-year-old patient with intestinal occlusion due to a descending colon tumor, with carcinomatous ascites and secondary liver and lung determinations. Considering the risks associated with a surgical act in such a patient and the impossibility of performing a curative intervention, a self-expanding metallic colonic stent was mounted. The post-intervention evolution was favorable, the patient being discharged 48 hours later. Left colon cancer is diagnosed in the occlusive phase in 8 to 26% of cases (1)...

BACKGROUND: The self-expanding metallic stent (SEMS) provides effective decompression for patients with malignant large bowel obstruction (MLBO); however, mechanical damage to malignant cells from insertion may negatively affect prognosis, similar to surgical manipulation, and its oncological safety is unclear. We examined mechanical damage from SEMS placement using circulating cell-free DNA (cfDNA) and circulating tumor DNA (ctDNA). METHODS: Between 1 November 2014 and 30 June 2017, 35 MLBO patients were analyzed, comprising 25 SEMS patients and 10 transanal decompression tube (TDT) patients (control)...

AIM: To evaluate the length and location of stenosis in the colon as predictors of technical and clinical outcomes of stent placement in patients presenting with obstructive colorectal cancer. METHODS: A prospective single-center cohort study of patients treated with a colonic stent for malignant obstruction, regardless of stenosis length or location. Stenosis length was assessed globally on the appropriate CT slice as well as by 3D CT reconstruction. We analyzed whether outcomes were different in patients with a right sided-tumor and/or a stenosis >4 cm long...

Great debate exists in the initial acute management of large bowel obstruction from obstructing left colon carcinoma. While endoscopic stenting is well established as the first approach in the setting of palliative care of patients with advanced metastatic disease as well as a bridge to elective surgery in elderly patients who have an increased risk of postoperative mortality (age >70 years and/or ASA status ≥3), controversies exist regarding oncological safety and long-term outcomes of endoscopic colonic stenting in younger patients and ESGE Guidelines do not recommend SEMS placement in patients <70 and fit for curative surgery...

INTRODUCTION: Emergency resection represents the traditional treatment for left-sided malignant obstruction. However, the placement of self-expanding metallic stents and delayed surgery has been proposed as an alternative approach. The aim of the current meta-analysis was to review the available evidence, with particular interest for the short-term outcomes, including a recent multicentre RCT. METHODS: We considered randomized controlled trials comparing stenting as a bridge to surgery and emergency surgery for the management of left-sided malignant large bowel obstruction, performing a systematic review in MEDLINE, PubMed database, and the Cochrane libraries...

BACKGROUND AND AIMS: Self-expandable metal stents are used increasingly in the treatment of obstructing colorectal cancer (CRC). Although endoscopic colon stenting is widely accepted in palliation, disagreement exists about its role in a curative setting. This study aims to describe long-term survival data in a large patient group treated with colon stenting as a bridge to surgery for CRC. METHODS: This prospective study included 97 patients who presented in a Belgian hospital between 1998 and 2013 with obstructing, although potentially curable, CRC...
