Forceps Biopsies Are Not Reliable in the Workup of Large Colorectal Lesions Referred for Endoscopic Resection: Should They Be Abandoned?

CONCLUSIONS: This study demonstrates that cancer-negative forceps biopsies of large colorectal polyps, referred for endoscopic resection, are not reliable. Considering that endoscopic resection of lesions containing superficial cancer is plausible, the clinical value of forceps biopsies in lesions suitable for endoscopic resection is questionable. See Video Abstract at http://links.lww.com/DCR/A984. LAS BIOPSIAS CON FÓRCEPS NO SON CONFIABLES EN EL ESTUDIO DE LAS LESIONES COLORRECTALES GRANDES REFERIDAS PARA RESECCIÓN ENDOSCÓPICA: ¿DEBERÍAN ABANDONARSE? ANTECEDENTES: Las biopsias se obtienen de forma rutinaria en el estudio de pólipos colorrectales grandes previo a resección endoscópica. OBJETIVO: Analizar que tan confiables son las biopsias en cuanto a reflejar la verdadera histopatología de los pólipos colorrectales grandes, en la rutina clínica. DISEÑO: Este es un estudio retrospectivo. AJUSTES: Los datos de pacientes sometidos a polipectomía de pólipos colorrectales grandes en la unidad de endoscopia, en Skåne University Hospital Malmö, entre enero de 2014 y diciembre de 2016 fueron examinados. PACIENTES: Un total de 485 lesiones colorrectales se biopsiaron dentro de un año antes de la resección endoscópica completa. Las muestras obtenidas mediante biopsia se compararon con las muestras completas resecadas en términos de...

Conclusion CSP is underutilized for small polyp resection despite its favorable safety and efficacy. Benign polyps are commonly referred for surgery and overt SMIC is underappreciated using endoscopic imaging. Addressing these issues may reduce diathermy-related adverse events, surgery, and unnecessary colonoscopic procedures for patients and reduce rates of post-colonoscopy colorectal cancer.

AbstractPurposeTo determine if there is an association between diverticular disease and colon cancer diagnoses with a secondary outcome of assessing other known risk factors for colon cancer. Colon cancer and diverticular disease have many shared symptoms and risk factors; the association between the two has been debated for many years.Methods36 cases of colon cancer and 144 age- and sex-matched controls were identified from records at an outpatient endoscopy center in Georgia. These cases and controls then were subject to a retrospective chart review to obtain any known risk factor data points for both diverticular diseas...

Abstract While colonoscopy is considered the gold standard for colon cancer screening, recent advancements in endoscopes have allowed for improved visualization of the colonic mucosa and improved polyp detection rates. Newer technologies also allow for assessment of structural changes for polyp discrimination and determination of histologic type. Classification of polyps prevents the need for a histopathologic report, which requires the additional time and expertise of a pathologist and adds to the overall cost. This review considered advances in endoscopic technologies reported in PubMed over the past 12 years. T...

ConclusionThe fusion fascia of Fredet is useful to achieve CME and D3-L in right colon cancers with reduced risk of intraoperative complications. This structure is particularly suitable for minimally invasive surgery; therefore, we encourage awareness of the fascia of Fredet by colorectal surgeons.

Authors: Gupta V, East JE Abstract Serrated polyps are considered precursor lesions that account for 15% to 30% of colorectal cancers, and they are overrepresented as a cause of interval cancers. They are difficult to detect and resect comprehensively; however, recent data suggest that high definition endoscopy, chromoendoscopy (via spray catheter, pump or orally), narrow band imaging, split-dose bowel preparation and a slower withdrawal (>6 minutes) can all improve detection. Cold snare resection is effective and safe for these lesions, including cold snare piecemeal endoscopic mucosal resection, which is likel...

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.
