Five children presenting with chronic and intermittent rectal bleeding were diagnosed as having colorectal polyps by fibreoptic colonoscopy performed under sedation. Three of the children had had barium-enema films reported on as normal. Eight polyps were seen, of which six were proximal to the sigmoid colon. All were removed endoscopically (one by proctoscopy, one by snare-intussusception) wit...

Surveillance is becoming common in the practice of colonoscopy because a large number of patients with colorectal polyps are now being discovered as a result of the increased use of colorectal cancer screening, and particularly because of the dramatic increase in screening colonoscopy. Although the term ‘colorectal polyp’ is not synonymous with colorectal adenoma, two-thirds of colorectal polyp...

This retrospective study shows that endoscopic polypectomy is the technique of choice to remove the majority of polyps; follow-up and pathologic examinations shed light on the carcinogenesis of colorectal lesions. From January 1990 to December 2001, 1302 adenomatous polyps were removed, 1175 endoscopically, 127 with surgical procedures. The anatomical and morphologic conditions of the colon and...

A 69 year-old man was referred to our department for polypectomy after a previous colonoscopy for colorectal cancer screening revealed three pedunculated polyps in the colon. The subsequent colonoscopy confirmed the presence of one polyp with 10 mm in the transverse colon, and two in the sigmoid, about 15 mm each; conventional snare polypectomy was performed, without complications. The microsco...

cer mortality in Taiwan, with more than 4,500 people dying of this disease in 2009. Malignant colorectal polyps represent the majority of early colorectal cancers. The term “malignant polyp” refers to a macroscopically benign appearing adenoma in which the invasive carcinoma is detected after histologic examination of the resected specimen. The muscularis mucosa must be breached to be defined a...

Peutz-Jeghers syndrome is a rare hereditary autosomal dominant disease caused by a mutation of the tumor suppressor gene serine/threonine kinase 11 located in chromosome 19p13.3. It is characterized by the presence of extensive mucocutaneous pigmentation, especially of the lips and the occurrence of hamartomatous polyps throughout the gastrointestinal tract. Gastrointestinal hamartomas occur pr...

Colorectal mucoceles usually arise in the appendix, and colonic disease is very rare. We report the first case of a mucocele of the colonic liver flexure that was treated successfully with endoscopy. A 36-year-old man was admitted to our hospital because of abdominal distension persisting for 3 days. Colonoscopic examination revealed a round polyp in the hepatic flexure, and we performed hot sn...

Colorectal polypectomy is an efficacy method for the prevention of colonrectal cancer, indeed, removing cancer precursor, reduces CRC incidence e mortality [1,2]. Despite proven effectiveness, polyp resection techniques are limited by lack of evidence and are based on expert opinion and uncontrolled observational studies [3-5]. Proper removal of polyp needs not only skillness by experienced end...

OBJECTIVE a) to evaluate the appropriateness of histological criteria as proposed by Morson as indicators for surgery; and b) to compare the adequacy of Morson s criteria with Haggitt s levels as indicators for surgery in the case of malignant sessile lesions. MATERIAL AND METHODS we carried out a prospective, protocolized study of 42 patients with polyps with invasive carcinoma (IC) who unde...

The detection and removal of adenomatous polyps and postpolypectomy surveillance are considered important for the control of colorectal cancer (CRC). Surveillance using colonoscopy is an effective tool for preventing CRC after colorectal polypectomy, especially if compliance is good. In current practice, the intervals between colonoscopies after polypectomy are variable. Different recommendatio...
