A total of 155 cases of Meckel's diverticulum were analyzed: 122 were uncomplicated as opposed to 33 that were complicated. Resection of all uncomplicated diverticula had a course free of difficulty, while there was one death in the cases with complicated diverticula as a result of peritonitis after perforation of the diverticulum. The diagnosis and differentiation of diverticulum from other abdominal clinical pictures, as well as from appendicitis, is usually not possible preoperatively, although differential diagnosis must always be kept in mind. If there are no special contraindications, Meckel's diverticulum is searched for instead and then resected.
