Oncological results of emergency operations for right-sided colorectal cancer

Objective . To study the oncological treatment results of patients with right-sided complicated colorectal cancer. Material and methods . The presented study analyzed the treatment results of 38 patients: with acute intestinal obstruction (23 patients) and peritonitis caused by tumor destruction with its perforation (15 patients). The surgical stage of treatment consisted of performing a right-sided hemicolectomy with the formation of an end-to-side small-colonic anastomosis according to the technique adopted at the department (patent No. 2709253). The frequency of 3- and 5-year survival and the presence of cancer progression were assessed. Results. In acute intestinal obstruction, the 3-year survival rate was 78%, 5-year survival – 43%. In case of tumor perforation with peritonitis, the 3-year survival rate is 53%, while progression was detected in only 20% of patients. Discussion . According to modern literature, in case of tumor disintegration with perforation and peritonitis, the 3-year relapse-free survival rate is from 15% to 42%, in case of acute intestinal obstruction, the 5-year survival rate is up to 42%, and the 3-year survival rate is up to 78%. Our results are consistent with these statistics. Conclusion . Radical surgeries for complicated cancer of the right half of the colon are applicable in practice, and the oncological treatment results correspond to the data published by other clinics.
