This chapter describes various techniques that can be employed to assist in the removal of colon polyps that are considered to be large or ‘difficult.’ Size alone is only one of the features that may cause some hesitation in making the decision to attempt polyp removal. Other factors that are related to the perceived level of difficulty are polyps that are flat and only slightly elevated above ...
Endoloop-assisted polypectomy may minimize the risk of bleeding after endoscopic resection of large pedunculated colorectal adenomas [1–3]. To the best of our knowledge, this is the first report of a rare complication of this technique caused by adhesion of the snare and endoloop. A 67-year-old man was referred to our endoscopy unit for polypectomy of colorectal adenomas detected during a colon...
poma and reduces bleeding from the biopsy site. Haemostatic clips were then applied to reduce the risk of perforation. Histopathology confirmed the polyp to be a tubular adenoma which was completely excised. Adenomatous polyps of the appendix are rare [1] with an incidence of 0.004–0.08% [2] . They pose hurdles in management due to difficulties in biopsying and excising these lesions endoscopic...
There is indirect evidence to suggest that 80% of colorectal cancers (CRC) develop from adenomatous polyps and that, on average, it takes 10 years for a small polyp to transform into invasive CRC. In multiple cohort studies, colonoscopic polypectomy has been shown to significantly reduce the expected incidence of CRC by 76% to 90%. Colonoscopic polypectomy is performed frequently in primary out...
A 66-year-old manwas referred to our department for screening colonoscopy. A polyp was found in the sigmoid colon (size 25mm, Paris classification 0-Ip, narrow-band imaging international colorectal endoscopic [NICE] classification 2). After the submucosal injection of diluted epinephrine and lifting (●" Fig.1), endoscopic mucosal resection was done. Immediately after the procedure, spurting pos...
Endoscopic retrieval of proximally migrated biliary plastic stents may be technically challenging and sometimes unsuccessful. Here we report the case of a 59-year-old woman with a migrated biliary stent in the right hepatic duct, which was diagnosed after the patient presented with cholangitis. The patient presented with constant abdominal pain in the right upper quadrant lasting for two days, ...
