RAMOS PACHON, Carlos Manuel  and  DEL VALLE LLUFRIO, Pedro. Periampullar diverticula diagnosed under endoscopic retrograde cholangiopancreatography. Rev. Med. Electrón. [online]. 2014, vol.36, n.3, pp. 258-264. ISSN 1684-1824.

Background: with the development of digestive endoscopy, Ryan and collaborators carried out the first endoscopic diagnose of duodenal diverticulum in 1984. The duodenum is the second place of the digestive duct where diverticula are detected more frequently, about 75 % of them located in the second portion of the duodenum. The diverticulum presence in the second portion of the duodenum, periampullar ones, has been reported in between 5 % and 32,8 % of patients in the series of endoscopic retrograde cholangiopancreatography studies. Objective: to determine the frequency periampullar diverticula were diagnosed during endoscopic retrograde cholangiopancreatography and to characterize these patients. Methods: a descriptive, cross-sectional study was performed in patients treated by endoscopic retrograde cholangiopancreatography from February 23rd, 2010 to February 23rd, 2013, being the population based study 35 patients with diagnose of periampullar diverticulum by endoscopic retrograde cholangiopancreatography. The following variables were analyzed: age, sex, diverticulum location with respect to the major papilla and cholangiographic diagnose. Patients were classified according to Noda´s classification. Results: there were not significant differences regarding to sex, and patients´ average age was 68,9 years. Type D patients prevailed and the most frequent cholangiographic diagnose was choledocholithiasis. Conclusions: the incidence of periampullar diverticulum in the studied population is between  the ranges reported by medical literature, with a patients´ average age of 68,9 years, being  choledocholithiasis the most frequent cholangiographic associated diagnose; the particularity of this case series is that there were not found  differences between sexes, and type D patients predominated.
