Abstract: Background: Diverticula are commonly observed in the duodenum. Duodenal Diverticulum
(DD) usually does not give symptoms throughout life and is diagnosed by coincidence. However,
it may present with different symptoms in patients.
Objective: This study aims to evaluate the prevalence of DD and Juxtapapillary Duodenal Diverticulum
(JDD) and its association with other possible pathologies and to determine its clinical impact
by using Computed Tomography (CT).
Methods: This retrospective observational study, which was taken consecutively between the years
of 2013-2020, was evaluated in the Radiology Department. The total number of cases was 4850
(male-2440; female-2410). CT images were evaluated by two experienced radiologists at the workstation.
DD and JDD prevalence and clinical findings in the hospital registry system were examined.
Results: The age of the patients included in the study ranged from 17 to 92 years (mean age
46.94±16.42). In patients with DD (female-130; male-101), mean age was 62.24 ± 12.69 (21-92).
The prevalence of DD was 4.76% (n=231). The prevalence of JDD was 4.02% (n=195) and increased
with age (p<0.01). The average diameter of the JDD was measured as 23.29±8.22
(9.5-55.3) mm. A significant positive correlation was found between age and DD diameter
(p=0.039). DDs were found most commonly 84.42% (n=195) in the second segment of the duodenum
as JDD. In patients with JDD, the mean diameter of choledochus and wirsung canal were 6.7
± 2.4 (3-15.3) mm and 0.31 ± 0.1 (0.1-6.5) mm respectively. The choledochal diameter was correlated
with the JDD size (p = 0.004). Cholelithiasis (n=56), choledocholithiasis (n=20), cholecystitis
(n=52), diverticulitis (n=15), duodenitis (n=37), pancreatitis (n=5) and hiatal hernia (n=60) with
JDD were observed. Periampullary carcinoma was detected in one patient.
Conclusion: Our study shows that cholelithiasis, choledocholithiasis, cholecystitis, diverticulitis,
duodenitis, pancreatitis may be associated with JDD. Therefore, in contrast-enhanced abdominal
CT scans taken for various reasons, investigation of the presence and characteristics of JDD and detection
of pathologies that may be associated with JDD are important for patients to benefit from
early diagnosis and treatment opportunities and to take precautions against possible complications.
