[In-patient psychoanalytical psychotherapy of a 12 year old boy with secondary encopresis].

Case report on the in-patient psychoanalytical psychotherapy of a 12 year old boy, who developed a nonorganic encopresis at the age of nine after his mother died. One focal issue is his denial of this loss and the beginning of a process of mourning due to the treatment. The Operationalized Psychodynamic Diagnostics (OPD) for Children and Adolescents are illustrated for this case.
