Synchronous colorectal carcinomas occurred in 5.5% of patients. Complete colonoscopy is vital for early detection and proper treatment of these complex cases.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Colorectal Surgery

Background:

  • Colorectal neoplasms require thorough investigation due to potential for multiple tumors.
  • Understanding the incidence and characteristics of synchronous colorectal carcinomas is crucial for effective patient management.

Purpose of the Study:

  • To determine the incidence of synchronous colorectal carcinomas in surgically treated patients.
  • To analyze diagnostic procedures, detection timelines, pathology, and treatment strategies for these cases.

Main Methods:

  • Retrospective study of 360 patients with surgically treated colorectal neoplasm between 1982 and 1990.
  • Analysis of patient records, including diagnosis, pathology reports, and treatment outcomes.

Main Results:

  • The incidence of synchronous colorectal carcinomas was 5.5% (20 cases).
  • Only 30% were diagnosed preoperatively; 40% were discovered during pathological examination.
  • Synchronous colorectal polyps were found in 80% of patients; most synchronous carcinomas were well-differentiated (65% Dukes stage A).

Conclusions:

  • Complete preoperative pan-colonoscopy is recommended for all patients with colorectal neoplasms.
  • Partial colectomies are indicated for synchronous colorectal carcinomas when oncological criteria are met and the colon is fully explored.
