The pattern of intestinal obstruction in Malaysia

Area of Science:

• Gastroenterology
• Surgical Pathology
• Epidemiology

Background:

• Mechanical intestinal obstruction is a significant surgical challenge, particularly in developing regions.
• Understanding etiological patterns across diverse populations is crucial for targeted interventions.

Observation:

• A 5-year review of 261 patients (271 cases) with mechanical intestinal obstruction in a tropical developing country.
• Etiological patterns varied by ethnicity: adhesions were most common in Chinese patients, similar to Caucasians.
• External hernia was the leading cause in Malays, Indians, Pakistanis, and Ceylonese, unlike the higher incidence of intussusception and volvulus in Africa and India.

Findings:

• Operative mortality was 13.9%, comparable to Western series.
• Confirmed adverse factors included extremes of age, comorbidities, gangrenous bowel, large bowel obstruction, and malignancy.
• While fluid and electrolyte imbalance was frequent, intensive preoperative correction mitigated its impact.

Implications:

• Highlights the need for context-specific management strategies for intestinal obstruction based on regional and ethnic etiological differences.
• Emphasizes the importance of addressing common causes like adhesions and hernias in tropical developing countries.
• Demonstrates that with appropriate management, even frequent complications like fluid imbalance can be overcome, leading to comparable outcomes to developed nations.
