MCQ – 71133


A 69-year-old man with good past health complained of colicky abdominal pain, increasing abdominal distension, vomiting, and constipation. On general examination, he was afebrile, dehydrated and tachycardia. Abdominal examination showed a distended abdomen with visible peristalsis, and there was generalized abdominal tenderness but no mass could be palpated. Auscultation revealed tinkling and accentuated bowel sounds. There was no abdominal scar to indicate previous surgery. Laboratory investigations showed slightly elevated urea (probably related to dehydration) but were otherwise normal. A supine abdominal radiograph of this patient was performed. What can be the most probable diagnosis?


Acute Appendicitis


Small Bowel Obstruction


Large Bowel Obstruction


Peptic Ulcer
