BACKGROUND AND AIMS: Although colonic perforation is a dreadful adverse event associated with stent placement, data on this topic are sparse. We aimed to investigate the clinical outcomes of colonic perforation and factors related with its occurrence in patients who receiving self-expanding metal stents (SEMSs) for malignant colorectal obstruction. METHODS: We retrospectively reviewed the data of 474 patients with malignant colorectal obstruction who received endoscopic SEMS insertion from April 2004 to May 2011 in the Severance and Gangnam Severance Hospital...

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.

Malignant ureteral obstruction is usually caused by an extrinsic compression including intra-abdominal cancers. One of the treatment modalities decompressing the obstruction is applying stent to open the ureter. Metallic Stent is an effective instrument which we used for the first time in Iran in our patient who had a metastatic colon cancerwith a single kidney and we used a Novel, Double-Layered, Coated, Self-expandable Metallic Mesh Stent (Uventa Stent) to keep the ureter open. After six months of follow up with ureteroscopy, there was no obstruction any more...

Mesenteric ischemia is a rare disorder, with considerably high morbidity and mortality rates. It can manifest in several ways, including acute mesenteric ischemia, chronic mesenteric ischemia, nonocclusive mesenteric ischemia, mesenteric venous thrombosis, and colonic ischemia. Of these, acute mesenteric ischemia is the most severe form of intestinal ischemia, with a high mortality rate. The mainstay of therapy for mesenteric ischemia is surgical exploration and resection of infarcted bowel; however, medical therapy can play an important adjunctive role...

Background: Indwelling Double-J ureteral stenting is commonly used in urological practice and has various complications. This study aimed to assess the frequency of bacterial stent colonization and stent-associated bacteriuria after indwelling it for different time durations and to evaluate the significance of urinary cultures for identification of colonizing microorganisms. Materials and Methods: A prospective cross-sectional study was conducted. Midstream urine from 72 patients undergoing J stent insertion was investigated microbiologically before stent insertion and on the day of stent removal...

An 81-year-old patient with significant cardiac comorbidities, a history of sigmoid resection 6 years ago, and iliac bypass surgery 19 years ago presented with mild hematochezia for the previous 3 days. While hemodynamically stable at first, he developed massive bleeding during preparation for colonoscopy and underwent a short course of cardiopulmonary resuscitation. Colonoscopy revealed no active bleeding but a protuberance of the colonic wall and a coagulation clot. In ultrasonography immediately after endoscopy, a large aneurysm was diagnosed and diagnosis of an iliaco-colonic fistula was assumed...

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...

A 88-year-old female suffered of ileus due to advanced transverse colon cancer. Pneumonia was observed and nutrient condition was bad. Operation was found to be difficult because of the bad condition with complication on this present time. Self-expandable metallic stent(SEMS)was inserted to extend obstruction. But SEMS dropped out next day and SEMS, thicker than previous one, was reinserted. Main tumor was huge protruding tumor and the reason of ileus was invagination of the cancer. The fixation of SEMS was not so good, but the generalcondition was improved while a week after reinsertion of SEMS...

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...

Tissue engineering appears promising as an alternative technique for esophageal replacement. Mesenchymal stem cells (MSCs) could be of interest for esophageal regeneration. Evaluation of the ability of an acellular matrix seeded with autologous MSCs to promote tissue remodeling toward an esophageal phenotype after circumferential replacement of the esophagus in a mini pig model. A 3 cm long circumferential replacement of the abdominal esophagus was performed with an MSC-seeded matrix (MSC group, n = 10) versus a matrix alone (control group, n = 10), which has previously been matured into the great omentum...

Background: The experience with uretero-arterial fistulas has been limited. However, the aggressive treatment of pelvic tumors with surgical resection and radiotherapy, along with liberal use of ureteral catheters, has been attributed to an increase in their incidence. Unless they are promptly diagnosed and treated, uretero-arterial fistulas are associated with considerably high rates of morbidity and mortality. Urologists need maintain a high degree of suspicion for uretero-arterial fistula in high-risk patients...

The use of endoluminal stents to treat anastomotic leaks post oesophagogastric resection remains controversial. While some advocate stents to expedite recovery, others advise caution due to the risk of major morbidity and mortality. We describe a case of anastomotic leak following total gastrectomy for adenocarcinoma treated with a self-expanding metallic stent. Complications with the initial stent were treated with a further stent, which compromised the function of the oesophagus and eroded into the aorta, necessitating a colonic reconstruction and endovascular aortic stenting...

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...

BACKGROUND: Ureteral stents are commonly placed before colorectal resection to assist in identification of ureters and prevent injury. Acute kidney injury (AKI) is a common cause of morbidity and increased cost following colorectal surgery. Although previously associated with reflex anuria, prophylactic stents have not been found to increase AKI. We sought to determine the impact of ureteral stents on the incidence of AKI following colorectal surgery. METHODS: All patients undergoing colon or rectal resection at a single institution between 2005 and 2015 were reviewed using American College of Surgeons National Surgical Quality Improvement Program dataset...
