Summary
External hernias are the primary cause of acute intestinal obstruction. Other significant causes include ascariasis, volvulus, and intussusception, with late hospital presentation being a key factor in mortality.
Area of Science:
- Gastroenterology
- Emergency Surgery
- Abdominal Medicine
Background:
- Acute intestinal obstruction is a common surgical emergency.
- Understanding the diverse etiologies is crucial for timely intervention.
Purpose of the Study:
- To prospectively evaluate the causes and outcomes of acute intestinal obstruction in a large patient cohort.
- To identify key factors influencing patient mortality.
Main Methods:
- Prospective study of 3550 consecutive patients presenting with acute intestinal obstruction.
- Analysis of etiological factors, treatment strategies, and patient outcomes.
Main Results:
- External hernias, predominantly inguinal, caused 75% of obstructions.
- Ascariasis, sigmoid volvulus, and intussusception accounted for 18% of cases.
- Late hospital presentation was the primary cause of death (10%).
Conclusions:
- External hernias are the leading cause of intestinal obstruction.
- Prompt diagnosis and treatment of ascariasis, volvulus, and intussusception are essential.
- Reducing delays in seeking medical care is critical to improve survival rates.
