| Case Scenario|| |
A 44-year-old man with no comorbid illnesses presented with abdominal pain for 2 months and vomiting for 2 months with significant loss of weight and appetite and obstipation for 1 week. The pain was intermittent, mostly postprandial, located in the epigastric region with no radiation. He had vomiting after food intake, which was not bloodstained, nonbilious, and nonprojectile. He had worsening of the above symptoms for the past 1 week, associated with obstipation for 1 week. He also had decreased urine output for the past 2 days. He gives history of appendicectomy 5 years back. He was a smoker for the past 5 years and chewed tobacco for the past 3 years. Clinical examination showed a distended abdomen with visible intestinal peristalsis.
Chest and abdomen X-rays are shown below as show in [Figure 1] and [Figure 2].
| Questions|| |
- What is the abnormality seen on X-ray that correlates with symptoms?
- What is the probable diagnosis and treatment?
- What differential diagnoses can be considered?

1. Dilated bowel loops
The plain abdomen erect X-ray shows the right-sided distended loops with haustrations. Obstruction less likely as air is seen in distal and proximal bowel loops.
2. Large bowel obstruction-Cecal bascule
Cecal bascule is a cause of large bowel obstruction where there is folding of the cecum anteriorly over the ascending colon. It is one of the two types of cecal volvulus (the other being axial ileocolic). Cecal volvulus accounts for 1% of all adult intestinal obstructions and nearly 25%–30% of all cases of colonic volvulus. Cecal volvulus incidence peaks in ages 20–40 years with a slight male predominance.
It is caused by rotational torsion of the cecum or ascending colon along its own axis. The base of the cecum folds anteriorly over the ascending colon, creating a flap valve obstructing emptying of the cecum.
The plain X-ray film findings of cecal volvulus demonstrate a distended cecum.
Computed tomography (CT) abdomen demonstrates the signs of cecal obstruction and distention. The “Whirl sign” may be seen– this is a nonspecific sign on CT  where the twisting of the bowel around its mesentery gives the appearance of a “whirl.”
In hemodynamically stable patients, detorsion is typically followed by an ileocecal resection or a right colectomy. In unstable patients, a cecopexy (suturing the cecum to the abdominal side wall) with or without a cecostomy tube placement can be performed in lieu of a resectional procedure.
3. Differential diagnosis
[Table 1] [5-9] gives the differential diagnoses for this condition.
