The association between colorectal sessile serrated adenomas/polyps and subsequent advanced colorectal neoplasia
ConclusionsOur results suggest that there is not a strong association between SSA/Ps and subsequent advanced colorectal neoplasia during the 5 years following SSA/P removal.

Conclusions: Solitary PJPs did not recur in this study. Although examination of the entire gastrointestinal tract using esophagogastroduodenoscopy, enteroscopy, and colonoscopy is desirable to exclude Peutz-Jeghers syndrome, follow-up endoscopy after endoscopic polyp resection may be unnecessary, once the diagnosis of a solitary PJP is made.

Once it became clear that most colorectal cancers developed from premalignant colon polyps, screening colonoscopy with removal of these polyps became the focus of colon cancer prevention with demonstrable effectiveness. The brilliant simplicity of the flexible cautery snare quickly became the standard method for polypectomy, and the use of partial colon resections to remove precancerous colon polyps plummeted. As colonoscopy evolved with an emphasis on higher detection of adenomas and identification of subtle flat colon lesions such as sessile serrated adenomas, the need for improved polypectomy techniques has become obvious.
A key to successful colorectal cancer (CRC) prevention is complete colon polyp removal. The quality of colonoscopy is currently defined by how well we identify neoplastic lesions, as measured by adenoma detection rates (ADRs). A higher ADR correlates with lower rates of interval colon cancers.1 However, the completeness and skills of resection are important factors as well, but they are not current quality metrics and would be an onerous task to measure in daily practice.
ConclusionColon polyps are incompletely resected in a small but potentially significant percentage of cases. IRR are similar with the use of cold jumbo forceps and cold snare. Use of cold jumbo forceps may result in more successful tissue retrieval as compared to cold snare.
This study seeks to explore the relationship between an endoscopist ’s ADR and the total number of right versus left colon polyps removed per procedure per endoscopist.
Incomplete resection of colorectal neoplasia decreases the efficacy of colonoscopy and contributes to post-colonoscopy colorectal cancer. Conventional endoscopic resection (CR) of polyps, performed in a gas-distended colon, is the current standard, but incomplete resection rates (IRR) of approximately 3-25% for non-diminutive (>5mm) non-pedunculated lesions are reported. Underwater endoscopic resection (UR), a novel technique utilizing advantages of water-aided colonoscopy, may help reduce IRR.
Screening colonoscopy decreases the risk of colon cancer through detection and removal of early precursors including adenomas and serrated polyps. Different devices to designed to improve colonic visualization have shown promising results increasing overall polyp detection rate and adenoma detection rate (ADR).
A 67-year-old woman was admitted to our department for one-month duration of asthenia. She was previously operated of upper right lobectomy for a high-grade sarcomatoid carcinoma. The patient was hemodynamically stable. Hemoglobin was 5.4 g/dL, and she was transfused with three blood units. An upper gastrointestinal endoscopy was carried out and it was unremarkable; a colonoscopy was then performed and a voluminous ulcerated polyp with a large base of implantation of the proximal descending colon was seen and removed without compl ications (Fig.
CONCLUSION: Also in our experience adenomatous polyps play a crucial role in the development of colorectal cancer. Therefore, it seems quite essential to avert colorectal cancers gradually. Colonoscopy is a non-invasive method of diagnosis and a treatment of colorectal polyps. Proper and careful colonoscopy examination is indispensable in the discovery of colorectal polyps and subsequent follow-up. Timely and routine colonoscopy is considered as an important approach for thwarting the development of malignant neoplasms.
