Tumors of a large intestine

Tumors, high-quality and malignant, occupy one of the leading places in structure of diseases of a large intestine. According to total statistics, 22-27% fall to their share (Fedorov V.D. et al., 1984; Fedorov V.D., Nikitin A.M., 1985; G. I. Sparrows et al., 2001; Hunt R.H., Waye J.D., 1982; Jensen A. et al., 1995; Harpaz N. et al., 2002). Now the kolonoskopiya, undoubtedly, is the main diagnostic method of this pathology. Compliance of the macroscopic signs characteristic of different types of tumors, their histologic structure, allows to use morphological classification in endoscopic practice as the full and the experts meeting the requirements of the majority (Parfyonov A.I., 2002; Bond J.H., 1995; 2001; Rex D.K. et al., 1999; Winawer S.J. et al., 2000).

Taking into account a cellular texture of an intestinal wall allocate the following groups of tumors (WHO, 1981):

  1. EPITHELIAL TUMOURS

A. High-quality
B. Malignant

  1. CARCINOIDS
  2. NOT EPITHELIAL TUMOURS

A. High-quality
B. Malignant

  1. TUMOURS OF THE HEMOPOIETIC AND ADENOID TISSUE
  2. NOT CLASSIFIED TUMOURS
  3. SECONDARY TUMOURS
  4. OPUKHOLEPODOBNY DEFEATS
  5. Gamartoma

B. Heterotopy

  1. Hyperplastic (metaplastic) polyp

G. High-quality lymphoid polyp and polyposes
D. Inflammatory polyp
E. Deep cystous colitis
Zh. Endometriosis
