[Duodenal diverticula and its relations with choledocholithiasis].

The incidence of duodenal diverticula was accomplished by four different methods (autopsy, post operative cholangiography, ERCP and upper gastrointestinal X rays); the relationship with common bile duct stones, also was analyzed. The study was developed in the José Joaquín Aguirre Clinic Hospital and Paula Jaraquemada Hospital. The lower incidence was 0.72% in autopsy group and the highest was 8% in patients diagnosed by ERCP. All the diverticula were unique and located in the second duodenal portion. A minimal difference in sex groups was encountered. We did'nt find a major incidence of choledocholithiasis in the population with duodenal diverticula.
