Background and study aims Colonic polyps > 1 cm in size are commonly managed using hot polypectomy techniques. The most frequent adverse events (delayed bleeding, post-polypectomy syndrome, and perforation) are related to electrocautery-induced injury. We hypothesized that cold resection of large polyps may have similar efficacy and improved safety compared to hot polypectomy. Our aims were to evaluate efficacy and safety of piecemeal cold snare resection of colonic polyps > 1 cm. Patients and methods Patients undergoing lift and piecemeal cold snare polypectomy of non-pedunculated colon polyps > 1 cm from October 2013 to September 2015 were identified retrospectively...

OBJECTIVES: The decision to perform secondary surgery after endoscopic resection of T1 colorectal cancer (CRC) depends on the risk of lymph node metastasis and the risk of incomplete resection. We aimed to examine the incidence and risk factors for incomplete endoscopic resection of T1 CRC after a macroscopic radical endoscopic resection. METHODS: Data from patients treated between 2000 and 2014 with macroscopic complete endoscopic resection of T1 CRC were collected from 13 hospitals...

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...

An unusual case of a polypoid, malignant gastric tumor in a 62-year man is presented. Endoscopy and subsequent polypectomy revealed an 8.5 x 6.5 x 4.5cm lesion in the body of the stomach. Microscopy showed surface dysplasia with an invasive adenocarcinoma displaying prominent tubulopapillary areas composed of large vacuolated cells, pleomorphic nuclei and occasional cytoplasmic hyaline globules. This component then blended with tubular structures lined by more primitive appearing vacuolated cells embedded within a stroma made up of cellular primitive, high-grade blastema-like areas and, less cellular more pleomorphic foci with spindle and several bizarre, large cells...

A 60-year-old woman underwent colonoscopy for a positive fecal immunochemical test. A 5 mm sessile polyp (Paris type 0-Isp) was found in the lower rectum (Figure 1a). This polyp was diagnosed as a low-grade adenoma based on findings of magnification colonoscopy with narrow band imaging (Figure 1b) and then was resected in a single piece with cold snare polypectomy.

BACKGROUND & AIMS: The current guidelines for surveillance after polypectomy do not distinguish between diminutive (1-5 mm) and small (6-9 mm) polyps with low-grade dysplasia (LGD). We aimed to evaluate the risk for advanced neoplasia on follow-up colonoscopy. METHODS: We retrospectively analyzed 443 subjects whose worst finding at index colonoscopy was polypectomy of 1 to 5 or 6 to 9 mm polyps with LGD, and those who underwent a follow-up colonoscopy. RESULTS: During a mean follow-up of 32...

A man aged 65 years presented with symptomatic anaemia without overt gastrointestinal bleeding. An oesophagogastroduodenoscopy (EGD) was performed and he was found to have a large ulcerated pedunculated Brunner's gland hamartoma in the duodenal bulb. The polyp was resected using snare cautery in forward and retroflexed positions. Colonoscopy was also performed and a few diminutive polyps were resected. A year later, the patient returned for a surveillance EGD, and no residual polyp was noted. Haemoglobin and iron studies normalised within a few months after polypectomy, with resolution of symptoms...

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...
