Abstract
Colorectal cancer remains one of the most prevalent malignancies
worldwide and a leading cause of cancer related death. Weakness, fatigue,
weight loss, iron deficiency anemia and abdominal pain are seen frequently in
patients with colon cancer diagnosed in advanced stages. Symptoms depend on
the stage of the tumor, early or advanced and its localization.
Right colon tumors are demonstrated with anemia, while left colon tumors
cause abdominal pain, rectal bleeding and obstruction .Colonoscopy is the gold
standard modality in screening for colon cancer. Its advantages include high
sensitivity, its capability of performing biopsy from the suspected areas and
possibility of polypectomy, when a polyp is seen. Other screening tests include
fecal occult blood test, flexible sigmoidoscopy and computed tomographic
colonography (virtual colonoscopy) .
Surgical resection including systematic lymphadenenctomy is the
treatment of choice. Unfortunately, only half of these curatively operated
patients will survive beyond five years. Up to 30 % of colorectal cancer patients
are first diagnosed during emergency department presentation due to
symptomatic disease.
Most of the resections for CRC are performed electively, however 15-
30% of those necessitate emergency surgical intervention . Obstruction,
perforation and bleeding are the most frequently encountered conditions
requiring surgery .Metabolic, cardiovascular, infectious or respiratory
comorbidities may develop in patients with complicated colorectal cancer. These
conditions substantially increase mortality .
So we aimed to Study of emergency presentation of colorectal tumors
and its impact on short term outcome with the aim of improving the awareness
of the disease and furthering research into more effective & affordable therapy.
