BACKGROUND AND AIMS: Self-expandable metallic stents are increasingly used in the treatment of obstructing colorectal cancer (CRC). Although endoscopic colonic 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 colonic stenting as a bridge to surgery (BTS) for CRC. PATIENTS AND METHODS: This prospective study included 97 patients who presented in a Belgian hospital between 1998 and 2013 with an obstructing, though potentially curable, CRC...

Self-expandable metal stents are often used to treat obstructive large bowel cancers. This study assessed the safety and efficacy of colonic stent insertion carried out in a district general hospital. Methods A retrospective review was carried out between 1 January 2007 and 28 February 2014 to identify patients who underwent stent insertion for malignant colorectal obstruction. Results Seventy-five patients (median age 75.2 years, 70.6% male) with primary colorectal cancer underwent stent insertion - 53 underwent semi-elective self-expanded metal stent insertion (for subacute bowel obstruction) and 22 had emergency stent inserted (for acute bowel obstruction)...

Video capsule endoscopy (VCE) has become the method of choice for visualizing the small bowel mucosa and is generally considered to be a safe method. Although uncommon, the most feared complication of VCE is capsule retention that can potentially lead to life-threatening bowel obstruction. Herein, we present for the first time a case of capsule retention in a colonic stent. The patient had known Crohn's disease with colonic involvement and underwent an uneventful but incomplete small bowel VCE for assessment of disease activity and extension for optimizing medical treatment...

Management of metastatic colorectal cancer requires accurate staging and multidisciplinary evaluation, leading to a consensus treatment plan with the ultimate goal of increasing survival and improving the quality of life, while taking into consideration the patient's performance status, disease burden, and goals of care. Since the introduction of multidrug chemotherapeutic regimens, survival of patients with metastatic colorectal cancer has improved. Many patients with unresectable disease are undergoing surgery for asymptomatic primary tumors despite evidence that it is usually a futile intervention...

The choice of necessary stent properties depends mainly on the length of the stenosis and degree of occlusion. So a stent design with variable radial stiffness along its longitudinal axis would be a good option. The design proposed corresponds to a tube-based stent with closed diamond-shaped cells made from a NiTi alloy. By acting independently on different geometric factors, variable geometries can be obtained with different radial force reactions. A design adjustment according to specific requirements, in order to get a better fit to ill-duct and reduces complications, is possible...

BACKGROUND AND AIMS: The colonic self-expanding metal stent (SEMS) has been widely used for "bridge to surgery" and palliative therapy. However, if the spread of SEMS is insufficient, not only can a decompression effect not be obtained but also perforation and obstructive colitis can occur. The mechanism of occurrence of obstructive colitis and perforation was investigated by flow dynamics. METHODS: Bernoulli's principle was applied, assuming that the cause of inflammation and perforation represented the pressure difference in the proximal lumen and stent...

A man in his 60s underwent gastrectomy to treat gastric carcinoma. Approximately 2.5 years after the surgery, he was admitted to the hospital because of abdominal pain. He was diagnosed with obstruction of the transverse colon due to a colon tumor. A stent was placed to treat the obstruction and avoid oncologic emergency. Biopsy results and imaging showed that the patient did not have colon cancer, but his previous gastric cancer had disseminated peritoneally. Chemotherapy was selected as treatment for recurrent gastric cancer...

We report a case of locally far-advanced colon cancer resected by laparoscopic surgery after colonic stent insertion and neoadjuvant chemotherapy. A 71-year-old man with obstructive symptoms was admitted to our hospital in July 2015. CT revealed a sigmoid colon tumor infiltrating the retroperitoneum and small intestine. Lower gastrointestinal endoscopy showed a sigmoid colon cancer. Self-expandable metallic stent insertion for obstructive colon cancer alleviated the patient's symptoms quickly. Four courses of neoadjuvant chemotherapy(XELOX)reduced the primary tumor in size, allowing for laparoscopic surgical resection...

Herein, we report 3cases of unresectable, advanced, and recurrent colorectal cancer associated with gastrointestinal obstruction. The patients were treated with small intestine-transverse colon bypass surgery, which improved the quality of life (QOL)in all cases. Case 1 was an 80-year-old woman who presented with subileus due to ascending colon cancer. After surgery, her oral intake was reestablished, and she was discharged home. Case 2 was an 89-year-old woman whose ileus was caused by cecal cancer with multiple hepatic metastases...

We report 2 cases of obstructive colorectal cancer that were successfully treated with a self-expanding metallic stent (SEMS). They were both diagnosed with obstructive colorectal cancer. Colonoscopy was performed to make a definitive and qualitative diagnosis and to relieve the stenosis using a SEMS. The SEMSs were inserted without complications. A few days later, the patients underwent laparoscope-assisted sigmoidectomy with lymph node resection. Despite the colon obstruction, a primary anastomosis was performed...

BACKGROUND: The aim of colonic stenting with self-expandable metallic stents in neoplastic colon obstruction is to avoid emergency surgery and thus potentially reduce morbidity, mortality, and need for a stoma. Concern has been raised, however, about the effect of colonic stenting on short-term complications and long-term survival. We compared morbidity rates after colonic stenting as a bridge to surgery (SBTS) versus emergency surgery (ES) in the management of left-sided malignant large-bowel obstruction...

Colonic complications are rare after acute pancreatitis but are associated with a high mortality. Possible complications include mechanical obstruction, ischaemic necrosis, haemorrhage, and fistula. We report a case of large bowel obstruction in a 31-year-old postpartum female, secondary to severe gallstone pancreatitis. The patient required emergency laparotomy and segmental bowel resection, as well as cholecystectomy. Presentation of obstruction occurs during the acute episode or can be delayed for several weeks...

The feasibility of endoscopic resection for synchronous early colon cancer after placement of self-expandable metallic stents (SEMS) for malignant colorectal obstruction is unknown. Herein we evaluated 3 cases of endoscopic resection for synchronous early colorectal cancers after SEMS placement. Patient 1 was an 82-year-old man with obstructive sigmoid colon cancer. We curatively treated the synchronous descending colon cancer with endoscopic submucosal dissection (ESD) and the rectal cancer with endoscopic mucosal resection (EMR) after SEMS placement...
