The Available online 23 November 2012 patient (female, 22 years old) was affected by duodenal Crohn’s disease.

The opened duodenum was anastomized side to side to a transmesocolic loop of the jejunum. After surgery, the general condition of the patient improved. DISCUSSION: Only two cases of fistula between a narrow duodenal bulb and the common bile duct have been described in literature and the Authors were not be able to verify the occurrence of a duodenal biliary fistula at surgery. The association between duodenal Crohn’s disease and Sphincter of Oddi incontinence is a very rare finding with different etiology: chronic intestinal pseudo-obstruction, common bile duct stones, progressive systemic sclerosis. CONCLUSION: The treatment to resolve Sphincter of Oddi incontinence for primary duodenal Crohn’s disease is not clear. Strictureplasty could be the treatment of choice, because, resolving the stricture, the duodenal pressure is likely to decrease and the reflux through the incontinent sphincter can be avoided. © 2012 Surgical Associates Ltd.

Sphincter of Oddi motility is controlled by cholecystokinin (CCK), which is released into the bloodstream by the duodenal mucosa, as a response to duodenal luminal acid and nutrients. Oddi’s Sphincter plays an important role in decreasing the basal pressure and the amplitude of phasic waves. The cause of SO incontinence is uncertain, and one potential mechanism may be a defect of the neural connec- tions that coordinate the interaction between the duodenum, the biliary tract and the SO. There is evidence that SO dysfunction may be a part of a generalized motor disorder of the gastrointestinal 15 tract, such as small intestinal dysmotility. In one study, patients with irritable bowel syndrome and SO dysfunction demonstrated paradoxical responses to CCK more often than patients with SO dys- 16 function alone.
