Note colorectal polyps before treatment?

Date2013-08-27 22:06:42

Principles of colorectal polyps are found polyps removed immediately . Currently removal of polyps various methods are mainly Endoscopic removal method.
According polyp morphology , size , quantity, and whether the pedicle , the length and thickness were used :
① frequency electric coagulation snare excision : mainly used pedunculated polyps ;
② high-frequency electric coagulation burning division : mainly used for multiple hemispherical small polyps ;
③ high-frequency electric coagulation hot biopsy forceps method : Currently very few applications , primarily ② ④ method instead ;
④ biopsy forceps division : mainly used for single or small number of globular small polyps , easy, and desirable biopsy ;
⑤ laser vaporization method and microwave diathermy ; suitable for those who do not need to leave the histological specimens ;
⑥ mucosal stripping embedded division : mainly used for flat polyps or early cancer ;
⑦ " close contact " removal method , mainly for long pedicle large polyps difficult by the use of large intestine polyps hanging wall adhesion electrocoagulation excision .
⑧ phases in the extraction method , mainly for 10 to 20 or more polyps in patients who can not be removed once .
⑨ endoscopy , surgery combined therapy, mainly for patients with polyps , polyps sparse areas with the upcoming surgery, so that you can achieve therapeutic purposes , but also to maintain the normal function of the large intestine .
Because of colorectal polyps , especially adenomatous polyps has been recognized as a precancerous lesion scholars , therefore, regular follow-up of patients with colorectal polyps has been referred to the height of the early prevention of colorectal cancer to understand . Colorectal polyps , especially adenomatous polyps, regular follow-up is important to prevent malignant polyps ring .
Polyp detection rates higher again , foreign reports ranging from 13% to 86% , a new addition to the detection of polyps grow again part of the residual polyp recurrence of polyps , some of colorectal polyps and omissions newborn polyps . In order to maintain intestinal polyp -free status , to prevent the occurrence of colorectal cancer to develop a cost-effective follow-up is necessary, the current international adenoma follow-up is necessary, the current international adenoma follow-up presented a variety of programs . In which the large intestine in the Third International Conference in Boston colorectal adenoma group convened in a more detailed discussion of the proposed scheme . They pointed out that the risk of developing new adenomas and adenomas in patients with localized adenoma recurrence after resection in adenomas vary, and therefore should be treated differently : Any individual , pedunculated ( or sessile but <2cm tubular adenoma ) , with light or moderate dysplasia adenomas are low- risk group . Where one of the following conditions is a high- risk group : multiple adenomas , adenomas diameter > 2cm, villous adenoma or mixed broad -based , adenoma with severe dysplasia or carcinoma in situ with adenomas had who have invasive cancer .
Follow-up programs in high-risk groups is adenoma, 3 to 6 months for endoscopy, such as negative every 6-9 months and then check once again as negative can check every year, such as the still negative, then every 3 years check the 1, but the need for fecal occult blood test during the year. In the low-risk group adenoma a review after adenoma removal, such as the negative can be checked once every three years, a total of two times, and then check once every five years, but in the follow-up period, subject to an annual fecal occult blood test. Once the review found that endoscopic removal of polyps.
