The opening of I. CŒLIOTOMY
When the abdomen is opened for the purpose of removing a diseased viscus, the operation receives a specific name, such as nephrectomy, gastrectomy, splenectomy, and so forth. In many instances the abdomen is occupied by a tumour which defies the skill of the surgeon to localize to any particular organ until it is exposed to view through an incision; it is usual to apply the term cœliotomy to an operation of this kind, and it merely implies that the belly is opened by a cut. Cœliotomy is a useful expression, because many abnormal conditions arise in the abdomen which require treatment through an incision in its walls which do not lend themselves to an expressive term, for example, the removal of omental cysts, the evacuation of pus, blood, or the removal of foreign bodies, &c. It is true that a cœliotomy performed on an uncertain diagnosis may become a colectomy, ovariotomy, hysterectomy, &c., and the preliminary step to the performance of the operations to be described in this section is an abdominal incision, or cœliotomy.
