ABSTRACT

INTRODUCTION: Primary omental torsion is a rare finding in cases of suspected acute abdomen. It is more common in children. Secondary omental torsion is typical for adults. CASE REPORT The authors describe two cases where pain in the right upper abdominal quadrant was caused by primary torsion of the omental corner due to increased intraabdominal pressure after a strong cough in one girl and after a workout in the other. Primary omental torsion usually mimics acute appendicitis with clinical findings in the right lower abdominal quadrant, especially in obese children. However, our two cases describe normosthenic girls with pain in the right upper abdominal quadrant up to the mesogastrium. CONCLUSION: Primary torsion of the omentum is a very rare cause of acute abdomen, which is also confirmed by its incidence in our group of patients where only two cases were seen during a 15-year period, which corresponds to 0.17% of all appendectomies performed in our department. This value is comparable to data reported in the literature. KEY WORDS acute abdomen omental torsion tenderness in right upper abdomen.
