“…Beim sog. Non-lifting-Zeichen [512,513] ist umstritten, ob es ein zuverlässiges Zeichen für Malignität ist [512,514], es kann aber zu einer technisch erschwerten und unvollständigen Resektion auch bei low-grade Adenomen führen [510].…”

“…Moss et al demonstrated the feasibility of piecemeal EMR in colorectal adenomas, reporting very high case-volumes in a multicenter collaboration. Their results (early recurrence rate 20.4%; morbidity 7.7%) have established a sound standard for future endoscopists pursuing similar proficiency [9].…”

“…However, piecemeal resection often leads to high rates of residual adenoma found during the follow-up period [7]. Two recently published prospective studies on the piecemeal EMR of colorectal adenomas, report residual adenoma rates as 20-38%, although, late recurrence was eventually diagnosed in less than 5% of these patients [8,9]. A previous systematic review, including 20 studies on EMR of large (>2cm) colorectal adenomas, described an early recurrence rate of 11.2% (after a single attempt), where the lesions were in fact residual adenomas rather than actual recurrences.…”

Gastrointestinal prekanseröz lezyonlarda endoskopik mukozal rezeksiyonun rolü ÖZ Amaç: Gastrointestinal maligniteler ve prekanseröz lezyonlarda endoskopik mukozal rezeksiyon (EMR) yaygın olarak kullanılmaktadır. Bu çalışmada amacımız gastrointestinal prekanseröz lezyonların tedavisinde EMR'un etkinliğini değerlendirmektir.Araç ve Gereçler: Binbeşyüz onsekiz hasta retrospektif olarak incelendi. Toplamda 59 hastaya EMR uygulandı. Lezyonlar 20 mm'den büyük ve 20 mm ve küçük olmak üzere 2 gruba ayrıldı. Mukozal görünüş ( Kudo pit patern yapısı) ve Paris sınıflamalarına göre lezyonlar kaydedildi. Hastalardan iki işlem denemesine rağmen polipleri tam çıkarılamayanlar cerrahiye yönlendirildi ve bu çalışmaya alınmadı. Yakın takipler esnasında saptanan tekrarlar kaydedildi.Bulgular: Elli dokuz hastadan toplam 94 polip rezeke edildi. Hastaların 42 ( %71,2)' sine enblok, 17 (%28,8 )'sine ise piecemeal rezeksiyon uygulandı. İki yöntem arasında yaş, cinsiyet, histopatoloji, komplikasyonlar, tekrar ve makroskobik tipler açısından farklılık gözlenmedi (P>0,05). 20 mm'den büyük poliplerde Kudo tip 4 görünüş ve adenomatöz polipler (P=0,001) yaygın olarak izlendi (P=0,03).Sonuçlar: Prekanseröz lezyonlarda EMR işlemi düşük komplikasyon ve kabul edilebilir tekrar oranları ile güvenli ve kullanışlı bir işlemdir. Kudo pit patern yapısı kanser riski değerlendirilmesinde rutin olarak kullanılmalıdır.

Objective: to compare endoscopic and histopathologic features of superficial, elevated lesions with one or more centimeters in diameter, diagnosed by videocolonoscopy on the distal and proximal colon, and subjected to mucosal resection. Methods: we conducted a retrospective, cross-sectional, observational study involving 8,075 videocolonoscopies. From this total, we evaluated 166 mucosectomies in 145 patients with superficial, elevated lesions with a diameter equal to or greater than 1cm. Results: the lesion prevalence was lower in G1 than in G2 (34.9% vs. 65%). The mean age, gender distribution and size (1.9cm in G1 versus 2.0cm in G2, p=0.921) were similar. There was no difference of mucosal surfaces in relation to the location (p=0.575). Considering Intraepithelial neoplasias, both the low grade, high grade (including carcinomas) and hyperplasic ones showedd no difference (p=0.527), nor did the neoplastic lesions when divided into serrated and non-serrated (p=0.124). Excluding 13 hyperplastic lesions and two carcinomas, 124 (82.1%) were non-serrated and 27 (17.9%), serrated. Conclusion: were found no significant differences between endoscopic and histopathological aspects of superficial, elevated lesions of 1cm or more in diameter in distal colon compared with the proximal, when resected by mucosectomy. Although not significant, there was a tendency of association between the location of the lesion and the presence of serrated features.
