Diverticula have occasionally been found in various parts of the alimentary tract. According to Buschi,1 the rarest diverticula are those of the stomach; then follow those of the duodenum, pharynx, esophagus, ileum and colon. All the early cases were discovered during postmortem examinations; they were not suspected during life and were in no way considered responsible for the death of the patient. The records show they are more frequently found in the bodies of people past middle life. Wilkie 2 states that 83 per cent. are found in people over 50 years of age. They were considered rare then, as they are now. However, it should be noted that during the last five years, more and more cases have been reported, and it seems probable that they are of more frequent occurrence than they were believed to be at one time.
