%X Background. Duodenum is the second most common site of diverticula after the colon. Diagnosis of duodenal diverticula is incidental and found during other therapeutic procedures. In 90% of cases, they are asymptomatic, and less than 10% develop clinical symptoms. The difficulty to ascertain the true incidence of duodenal diverticula demanded for the present study to elucidate the prevalence of the duodenal diverticulum in South Indians. Materials and Methods. One hundred and twenty specimens of duodenum were utilized for the study. The prevalence, anatomical location, and dimension of duodenal diverticulum were studied. Results. Among the 120 specimens of duodenum, five specimens had solitary, extraluminal, and globular-shaped diverticula in the medial wall of the duodenum. In three (60%) cases, it was found in the second part of duodenum and in two (40%) cases in the third part. The mean size of the diverticula was 1.4£¿cm. Conclusion. In the present study in South Indian people, the prevalence (4.2%) of duodenal diverticula is low comparable to other studies in the literature. Even though most of the duodenal diverticula are asymptomatic, the knowledge about its frequency and location is of great importance to prevent complications like diverticulitis, hemorrhage, obstructive jaundice, and perforation. 1. Introduction Duodenal diverticulum was first reported by a French pathologist Chomel in 1710 [1] and was diagnosed radiologically by Case [2] in 1913. Duodenum is the second most common site of diverticula in alimentary tract after colon, followed by jejunum, ileum, and stomach [3, 4]. Although associated with complications like diverticulitis, perforation, obstruction, or haemorrhage, the majority of duodenal diverticula are asymptomatic [5, 6], more often coming as a surprise on gastrointestinal series. Duodenal diverticula are found in 0.16 to 6% of upper gastrointestinal barium series and up to 23% of endoscopic retrograde cholangiopancreaticographies [6, 7]. However, reported incidence from cadaveric studies could be as high as 31.8% [8]. In recent review of the literature, there were a few cadaveric studies on the incidence of duodenal diverticulum throughout the world, and none from South India. To the best of our knowledge, the present study should be the first to highlight the prevalence and anatomical location of duodenal diverticula in South Indians. 2. Materials and Methods One hundred and twenty specimens of duodenum from 108 male and 12 female subjects, in the age group of 25 to 63 years, procured from the Department of Anatomy,
