|May 1, 1984
Summary
Acute intestinal obstruction is a common presentation of colorectal carcinoma, often incurable at diagnosis. Surgical outcomes vary by tumor location and treatment, with resection and anastomosis offering better survival than staged procedures.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Colorectal Surgery
Background:
- Colorectal carcinoma frequently presents with acute intestinal obstruction.
- A significant proportion of tumors are incurable at the time of diagnosis.
- Obstruction can be complicated by perforation, impacting surgical outcomes.
Purpose of the Study:
- To analyze the clinical features, management, and survival rates of colorectal carcinoma presenting with acute intestinal obstruction.
- To compare outcomes based on tumor location, presence of perforation, and surgical approach.
Main Methods:
- Retrospective analysis of 646 patients with colorectal carcinoma over six years.
- Identification of patients presenting with acute intestinal obstruction.
- Comparison of postoperative mortality and five-year survival rates based on treatment modalities and tumor characteristics.
Main Results:
- 19% of patients presented with acute intestinal obstruction; 42% had incurable tumors.
- Tumor location significantly impacted survival: right colon (36%) vs. rectum (5%).
- Resection with anastomosis showed superior five-year survival (48%) compared to staged procedures (18%).
Conclusions:
- Acute intestinal obstruction in colorectal carcinoma necessitates urgent management, with outcomes influenced by tumor curability and location.
- Surgical approach, particularly resection with anastomosis, is critical for improving long-term survival.
- Rectal tumors present a poorer prognosis compared to right-sided colon tumors.
