Abstract

Background/aims: Colorectal laterally spreading tumors are superficial tumors classified into two groups as granular (G-laterally spreading tumor) and non-granular (non-granular-laterally spreading tumor) types. In this study, we aimed to investigate the effi- cacy and feasibility of endoscopic submucosal dissection in the treatment of laterally spreading tumors. Materials and Methods: Forty-four laterally spreading tumors in 40 patients were treated with endoscopic submucosal dissection at a tertiary referral hos- pital. Patient data were collected retrospectively. In this study, we evaluated tumor size, macroscopic type, lesion location, histology, curative resection, and complications. Results: Of the 44 laterally spreading tumors excised by endoscopic submucosal dissection, 29 (65.9%) were G-laterally spreading tumor and 15 (34.1%) were non-granular-laterally spreading tumor. Most of the non-granu- lar-laterally spreading tumors were localized in the right colon, while most G-laterally spreading tumors were localized in the left colon (p<0.001). There was also no difference between G-laterally spreading tumors (6/29) and non-granular-laterally spreading tumors (2/15) with regard to exhibiting malignant features (p=0.69). Although median size (40 mm vs. 27.5 mm) and procedure ti- me (115 minutes vs. 60 minutes) for G-laterally spreading tumors were bigger and longer respectively, procedure time per cm2 was not different (8.9 minutes vs. 8.2 minutes) between the two groups. Curative resection rates for laterally spreading tumors were qui- te high (95.5%), while en bloc resection rates were low (77.3%). The rates of endoscopic submucosal dissection-related complications such as perforation, major and minor bleeding were low (4.5%, 2.3%, 6.8%, respectively). Conclusion: Endoscopic submucosal dis- section is an effective and safe therapeutic option with high curative rates for early-stage malignant and pre-malignant laterally spreading tumors not having an absolute indication for surgery, regardless of the lesion type and size.

Özet

Giriş ve Amaç: Kolorektal lateral yayılımlı tümörler, granüler (granüler-lateral yayılımlı tümör) ve nongranüler (nongranüler-la- teral yayılımlı tümör) tip olmak üzere 2 grupta sınıflandırılmaktadır. Bu çalışmanın amacı kolorektal lateral yayılımlı tümörlerin tedavisinde endoskopik submukozal diseksiyonun etkinliği ve kullanılabilirliğinin değerlendirilmesidir. Gereç ve Yöntem: Üçüncü basamak sağlık hizmeti veren hastanede endoskopik submukozal diseksiyon ile tedavi edilen 40 hastada 44 lezyonun verileri retrospektif olarak toplandı. Bu çalışmada tümör boyutu, makroskopik tipi, lezyon lokalizasyonu, histoloji, küratif rezeksiyon ve komplikasyonlar değerlendirildi. Bulgular: Endoskopik submukozal diseksiyon ile çıkarılan 44 lezyonun 29 (65.9%)u G-lateral yayılımlı tümör ve 15 (34.1%)i nongranüler-lateral yayılımlı tümör idi. Nongranüler-lateral yayılımlı tümörlerin çoğu sağ kolonda lokalize iken G-lateral yayılımlı tümörlerin çoğu sol kolon yerleşimli idi (p<0.001). Malignite her 2 lateral yayılımlı tümör tipinde de benzer oranlarda gözlendi (p=0.69). Her ne kadar G-lateral yayılımlı tümörlerde ortanca boyut (40 mmye karşın 27.5 mm)ve işlem süresi (115 dakikaya karşın 60 dakika) daha uzun olmasına rağmen her cm2ye düşen işlem süresi her 2 tipte de benzerdi (8.9 dakikaya kaşlın 8.2 dakika). En blok rezeksiyon oranları düşük olmasına rağmen (77.3%), küratif rezeksiyon oranı yüksekti(95.5%). Perforasyon, majör ve minör kanama gibi işleme bağlı komplikasyon oranları düşüktü (4.5%, 2.3%, 6.8%, sırasıyla). Sonuç: Endoskopik submukozal diseksiyon, lezyon tipi ve boyutuna bakılmaksızın, cerrahi için tedavi indikasyonları olmayan premalign ve erken evre malign kolorektal lateral yayılımlı tümörlerde yüksek kür oranları ile güvenli ve etkili bir tedavi seçeneğidir.
