Name of the Condition

  • Malignant neoplasm of splenic flexure (ICD-10 Code: C18.5)
  • Also known as splenic flexure cancer.

Summary

Malignant neoplasm of the splenic flexure is a cancer that originates in the splenic flexure, a bend in the large intestine near the spleen. This condition involves the abnormal growth of cells that can invade nearby tissues and spread to other parts of the body if not treated. It disrupts normal digestive function and may lead to systemic complications.

Causes

The exact cause is not fully understood, but it involves genetic mutations that lead to uncontrolled cell growth. Contributing factors may include chronic inflammation, dietary habits, and previous history of colorectal polyps.

Risk Factors

  • Age: Individuals over 50 are at higher risk.
  • Family history of colorectal cancer or polyps.
  • Personal history of inflammatory bowel disease.
  • Genetic conditions such as familial adenomatous polyposis or Lynch syndrome.
  • Lifestyle factors including smoking, obesity, and sedentary lifestyle.

Symptoms

  • Changes in bowel habits (e.g., diarrhea, constipation).
  • Blood in the stool or black, tarry stool.
  • Abdominal pain or discomfort, bloating.
  • Unexplained weight loss and fatigue.

Diagnosis

Diagnosis typically involves a combination of colonoscopy, biopsy, imaging studies (such as CT or MRI scans), and blood tests (including CEA test). Colonoscopy allows direct visualization and tissue sampling, while imaging helps assess tumor extent and metastasis.

Treatment Options

Treatment depends on the stage and may include surgery, chemotherapy, radiation therapy, or targeted therapy. Surgery often involves resection of the affected segment of the colon. Adjuvant therapies may be used to reduce recurrence risk.

Prognosis and Follow-Up

Prognosis varies based on stage at diagnosis, with earlier detection improving outcomes. Follow-up typically includes regular colonoscopies, imaging, and blood tests to monitor for recurrence or metastasis.

Complications

Potential complications include bowel obstruction, perforation, bleeding, and metastasis to other organs (e.g., liver, lungs). Treatment-related side effects (e.g., infection, chemotherapy toxicity) may also occur.

Lifestyle & Prevention

  • Maintain a high-fiber, low-fat diet.
  • Engage in regular physical activity.
  • Avoid smoking and limit alcohol consumption.
  • Screen regularly for colorectal cancer, especially if at higher risk.

When to Seek Professional Help

Seek medical attention for persistent changes in bowel habits, unexplained weight loss, blood in stool, or severe abdominal pain. Early evaluation is critical for timely diagnosis and treatment.

Tips for Medical Coders

Document the specific location (splenic flexure) and confirm malignant behavior. Ensure clinical documentation supports the diagnosis and stage, as coding accuracy depends on detailed anatomical and pathological details.
