Currently, several endoscopic resection (ER) methods for colorectal tumors are available, including polypectomy, conventional endoscopic mucosal resection (EMR), endoscopic submucosal dissection (ESD), and modified ER. In the present review, we mainly focus on the current status of ER for colorectal tumors as well as the report from the Endoscopic Forum Japan (EFJ) 2016, which was held in Tokyo in August 2016. The proposed ER methods for colorectal tumors larger than 10 mm in diameter are as follows. (i) Pedunculated-type tumor is an indication for polypectomy, regardless of size...

BACKGROUND/PURPOSE: Interval colorectal cancer (CRC) is an emerging issue in CRC screening and surveillance. The frequency of interval CRC and its associated factors have not been well studied in Eastern Asia. We aim to clarify the factors associated with interval CRC. METHODS: CRC patients who had negative colonoscopy results 6-36 months prior to cancer diagnosis were defined as cases of interval CRC. Patient characteristics, past history, colon preparation, colonoscopy findings, and pathology were retrospectively evaluated...

No single biological marker is used in routine diagnosis of colorectal cancer (CRC) in endoscopic biopsies. IMP3 is a good independent prognostic biomarker for CRC. However, the expression of IMP3 in hyperplastic polyp (HP) and adenoma has not yet been studied. Moreover, no studies have established the diagnostic value of IMP3 in biopsies. This study aims to assess IMP3 expression in HP, adenoma, and CRC in resection specimens and investigated its value in diagnosis of CRC in biopsies. A total of 1328 specimens (633 of polypectomy; 395 surgical resections; 300 biopsies) were retrospectively analysed...

Lifetime risk of developing colorectal cancer is 5%, and 5-year survival at early stage is 92%. Individuals with precancerous lesions removed at primary screening are typically recommended surveillance colonoscopy. Because greater benefits are anticipated for those with higher risk of colorectal cancer, scope for risk-specific surveillance recommendations exists. This review assesses published cost-effectiveness estimates of postpolypectomy surveillance to consider the potential for personalized recommendations by risk group...

Colonoscopy is the standard of care for screening and surveillance of colorectal cancers. Removal of adenomatous polyps prevents the transformation of adenomas to potential adenocarcinoma. While most polyps are amenable to simple endoscopic polypectomy, difficult polyps that are large, broad-based, or located in haustral folds or in tortuous colon segments can present a challenge for endoscopists. Traditionally, patients with endoscopically unresectable polyps have been referred for oncologic surgical resection due to the underlying risk of malignancy within the polyp; however, the majority of these polyps are benign on final pathology...

A complete colonoscopy is key in the diagnostic and therapeutic approaches to a variety of colorectal diseases. Major challenges are incomplete polyp removal and missed polyps, particularly in the setting of a difficult colonoscopy. There are a variety of both well-established and newer techniques that have been developed to optimize polyp detection, perform complete polypectomy, and endoscopically treat various complications and conditions such as strictures and perforations. The objective of this article is to familiarize the colorectal surgeon with techniques utilized by advanced endoscopists...

Colonoscopy and endoscopic removal of precancerous polyps play an important role in colorectal cancer (CRC) prevention. Improved endoscopes and quality standards have led to an increasing polyp and adenoma detection rate. Optimal polyp resection techniques and management strategies are key for an effective colonoscopy practice. Areas covered: Strategies for how to improve diminutive polyp (polyps up to 5mm in size) management are discussed because of their high prevalence. Systematic removal of diminutive polyps leads to increasing costs of colonoscopy practice, while the effect on colorectal cancer prevention might be negligible...

1 ESGE recommends cold snare polypectomy (CSP) as the preferred technique for removal of diminutive polyps (size ≤ 5 mm). This technique has high rates of complete resection, adequate tissue sampling for histology, and low complication rates. (High quality evidence, strong recommendation.) 2 ESGE suggests CSP for sessile polyps 6 - 9 mm in size because of its superior safety profile, although evidence comparing efficacy with hot snare polypectomy (HSP) is lacking. (Moderate quality evidence, weak recommendation...

Polypectomy reduces the incidence and mortality of colorectal cancer (CRC). The widespread adoption of CRC screening, more rigorous colonoscopy techniques, and advancements in endoscopic imaging have led to a greater awareness of complex polyps. Whereas surgery was once considered necessary for many large sessile or laterally spreading lesions (LSLs) in the colorectum, the majority can now be removed endoscopically. Endoscopic mucosal resection (EMR) is an established technique for treatment of colorectal LSLs...
