Abstract
Purpose and Objective: To detect retrospectively the duodenal diverticula in the routine abdominal CT and MRI.
Materials and Methods: Between March 2005 to June 2013, 151 incidental duodenal diverticulas were found out through 120.000 abdominal CT and/or MRI. Two abdominal radiologists evaluated the suspicious diverticula cases together with consensus. CT examinations were performed at 16 and 64 detector, Philips multislice CT and MR imaging was performed at 1.5 T Intera- Achievva, Philips Medical systems.
Results: Incidence of duodenal diverticula in this research was about 0.013%,112 diverticulas along the second part of duodenum, 3 at duodenal bulbus, 5 diverticulas at jejenum, 2 along fourth part of the duodenum, 37 along third part were discovered. 16 diverticula patients regarded complications, Urgent laparatomy was performed for 3 patients with perforated diverticulum, other complicated diverticulas were treated conservatively
Conclusion: Duodenal diverticula may lead to severe complications like perforation and/or diverticulitis, Multislice CT may show diverticulum in most cases, along with inflammatory exudates and surrounding extraluminal gas and contrast agent accumulation.
