In surgery, deep-seated fungal infection is not rare. In our institute, fungal infection was analyzed during postoperative periods. As pathogen, fungus was the second frequent pathogen after the operations for esophageal cancer and gastric cancer, and the third pathogen after hepatobiliopancreatic cancer and colon cancer. Furthermore, fungus was found more frequently pathogen from distant infection than that from local foci. Especially in CV catheter sepsis, fungus was main pathogen (60 %). In order to inhibit CV catheter sepsis, nutrition support team (NST) has been induced in our institute for prevention of external pathway of fungus. After NST, the frequency of CV catheter sepsis decreased from 12 % to 3.6 %, and the isolated frequency of fungus in catheter sepsis patients also decreased from 84 % to 16 %, respectively. It demonstrates that the activity of NST successfully prevents the external pathway of fungus in CV catheter indwelling patients. However, internal pathway (fungal translocation) still remains, and that issue has to be overcome. Molecular biological technique was applied for diagnosis of fungemia. PCR-RFLPs was performed by using specific primer of 18s rRNA in V4 region. Clinical samples were applied for PCR-RFLPs, and antifungal therapy was performed according as the results of PCR-RFLPs. It indicated that molecular biological technique was useful for diagnosis of fungemia.

D011183	Postoperative Complications	Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.	Complication, Postoperative,Complications, Postoperative,Postoperative Complication
D002404	Catheterization	Use or insertion of a tubular device into a duct, blood vessel, hollow organ, or body cavity for injecting or withdrawing fluids for diagnostic or therapeutic purposes. It differs from INTUBATION in that the tube here is used to restore or maintain patency in obstructions.	Cannulation,Cannulations,Catheterizations
D004866	Equipment Contamination	The presence of an infectious agent on instruments, prostheses, or other inanimate articles.	Contamination, Equipment,Contaminations, Equipment,Equipment Contaminations
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D016133	Polymerase Chain Reaction	In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.

D016469	Fungemia	The presence of fungi circulating in the blood. Opportunistic fungal sepsis is seen most often in immunosuppressed patients with severe neutropenia or in postoperative patients with intravenous catheters and usually follows prolonged antibiotic therapy.
