BACKGROUND: Although the initial clinical efficacy of self-expandable metal stents is acceptable, doubt still remains about long-term clinical outcomes and complications. OBJECTIVE: The aim of this study was to evaluate the stoma formation rate and risk factors for complications after successful stenting in patients with obstructive metastatic colorectal cancer. DESIGN: This was a tertiary-care center retrospective study. PATIENTS: From January 2000 to December 2010, 130 patients with unresectable obstructive colorectal cancer received successful self-expandable metal stent placement...

Endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR) are useful therapeutic techniques for colorectal tumors. Currently, new techniques based on these procedures are available, such as endoscopic submucosal dissection with snare (ESD-S) and endoscopic mucosal resection with pre-cutting (EMR-P). For the excision of colorectal tumors, each of these techniques has been characterized as having a high total resection rate, low recurrence rate or low complication rate. In this study, we analysed clinical trials that had recently been published, to search for the most appropriate endoscopic treatment for colorectal tumors...

Endoscopic resection is now considered a curative procedure for early gastric cancer. In Japan, it has increasingly replaced surgical resection for this indication, although in the West it has not been universally accepted as a first-line treatment. Recently, endoscopic submucosal dissection has been increasingly applied to colorectal disease, although it has not become a standard therapeutic procedure for early colorectal carcinoma because of its technical difficulty, the relatively long procedure time required, and the risk of complications, such as perforation and bleeding...

Accurate endoscopic diagnosis including pit pattern observation is necessary for performing definite endoscopic therapy. Endoscopic mucosal resection (EMR) is performed worldwide for early colorectal cancers 20 mm in diameter. Hyaluronic acid solutions as an injection solution have been used to achieve sustained mucosal elevation, definitive en-bloc resection, and complete resection. In Japan and some other Western and Asian countries, endoscopic submucosal dissection (ESD) is reported to be an efficient treatment with a high rate of en bloc resection for large early colorectal cancers and it is considered less invasive than laparoscopic colectomy...

BACKGROUND AND AIM: In recent years, the effectiveness of colorectal endoscopic submucosal dissection (ESD) has been increasingly reported. Herein, we highlight the most recent developments and technical advantages of colorectal ESD compared to EMR and minimally invasive surgery. METHODS: All candidate lesions for ESD were confirmed as being intramucosal tumors by colonoscopy. Presently, the indications for colorectal ESD approved by the Japanese government's medical insurance system are early colorectal cancers with a maximum tumor size of 2-5 cm; however, many early cancers >5 cm have been treated by ESD in referral centers...

Endoscopic mucosal resection (EMR) is an endoscopic alternative to surgical resection of mucosal and submucosal neoplastic lesions. Prior to the development of knives, EMR could be performed with accessories to elevate the lesion. After the development of various knives, en bloc resection was possible without other accessories. So, recently, simple snaring without suction or endoscopic submucosal dissection using knife in the epithelial lesions such as adenoma or early mucosal cancer has been performed. However, for easy and complete resection of subepithelial lesions such as carcinoid tumor, a few accessories are needed...

In recent times, the incidence of colorectal cancer(CRC)in Japan as well as in Western countries has been increasing, and the various treatment strategies for CRC include endoscopic mucosal resection(EMR), curative hepatectomy for a solitary liver metastasis, and chemotherapy. Although the 5-year survival rate of patients with stage I-III CRC after complete resection is high, when the disease recurs, approximately 70% of the recurrent tumors become unresectable. Most patients with unresectable recurrent CRC receive chemotherapy, and, in recent years, the survival benefit has improved greatly because of the addition of molecular targeted drugs...

Due to the widespread acceptance of gastric and esophageal endoscopic submucosal dissections (ESDs), the number of medical facilities that perform colorectal ESDs has grown and the effectiveness of colorectal ESD has been increasingly reported in recent years. The clinical indications for colorectal ESD at the National Cancer Center Hospital, Tokyo, Japan include laterally spreading tumor (LST) nongranular type lesions >20 mm and LST granular type lesions >30 mm. In addition, 0-IIc lesions >20 mm, intramucosal tumors with nonlifting signs and large sessile lesions, all of which are difficult to resect en bloc by conventional endoscopic mucosal resection (EMR), represent potential candidates for colorectal ESD...

The NCCN Clinical Practice Guidelines in Oncology for Colon Cancer begin with the clinical presentation of the patient to the primary care physician or gastroenterologist and address diagnosis, pathologic staging, surgical management, perioperative treatment, patient surveillance, management of recurrent and metastatic disease, and survivorship. The NCCN Colon Cancer Panel meets annually to review comments from reviewers within their institutions and to reevaluate and update their recommendations. In addition, the panel has interim conferences as new data necessitate...

BACKGROUND: Conventional endoscopic resection (CER) for early colorectal neoplasia (CRN) is widely accepted as a minimally invasive treatment. Endoscopic submucosal dissection (ESD) was developed in Japan to resect larger lesions, but ESD was not covered by the Japanese national health insurance until April 2012. In addition, treatment strategies vary considerably among medical facilities. To evaluate the current situation in Japan regarding endoscopic treatment of CRNs measuring ≥20 mm, we conducted a prospective multicenter study at 18 medium-volume and high-volume specialized facilities in cooperation with the Japan Society for Cancer of the Colon and Rectum (JSCCR)...

INTRODUCTION: Colorectal carcinoma can present with acute intestinal obstruction in 7%-30% of cases, especially if tumor is located at or distal to the splenic flexure. In these cases, emergency surgical decompression becomes mandatory as the traditional treatment option. It involves defunctioning stoma with or without primary resection of obstructing tumor. An alternative to surgery is endoluminal decompression. The aim of this review is to assess the effectiveness of colonic stents, used as a bridge to surgery, in the management of malignant left colonic and rectal obstruction...

AIM: This study involved a large nationwide Danish cohort to evaluate the hypothesis that a high lymph node harvest has a positive effect on survival in curative resected Stage I-III colon cancer and a low lymph node ratio has a positive effect on survival in Stage III colon cancer. METHOD: Analysis of overall survival was conducted using a nationwide Danish cohort of patients treated with curative resection of Stage I-III colon cancer. All 8901 patients in Denmark diagnosed with adenocarcinoma of the colon and treated with curative resection in the period 2003-2008 were identified from the Danish Colorectal Cancer Group (DCCG)...

BACKGROUND & AIMS: Treatment of large colorectal neoplasms (>20 mm in diameter) by conventional endoscopic mucosal resection (EMR) often results in piecemeal resection that requires further intervention. We evaluated the efficacy of EMR with circumferential incision (CEMR). METHODS: From March 2008-July 2009, we resected 24 large colorectal neoplasms measuring 20-40 mm in diameter by using the CEMR technique. CEMR was performed by using a ball-tip bipolar needle knife with a snaring technique...

Approximately 30% of patients with rectal cancer present with metastatic disease. Many of these patients have symptoms of bleeding or obstruction. Several treatment options are available to deal with the various complications that may afflict these patients. Endorectal stenting, laser ablation, and operative resection are a few of the options available to the patient with a malignant large bowel obstruction. A thorough understanding of treatment options will ensure the patient is offered the most effective therapy with the least amount of associated morbidity...
