Popis: Background Fungal infection is a devastating complication with an increased incidence in the past decade. Immune-depressed patients undergoing high-risk procedures have an increased incidence of surgical infection, particularly due to fungal colonization. Methods Twenty patients undergoing pancreas transplantation, 20 kidney transplant patients undergoing biliary tract surgery, 20 patients with human immunodeficiency virus (HIV) undergoing biliary tract surgery and 20 patients undergoing pancreatic resection for neoplasms were enrolled in a prospective study concerning perioperative surgical infection. All patients underwent surgical procedures by the same surgeon. All had preoperative blood counts, assay of CD lymphocyte populations, complete nutritional evaluation and similar antibiotic prophylaxis. Perioperative care was done to a similar standard and only patients undergoing pancreas transplantation received fungal prophylaxis (nystatin wash and swallow). In patients with clinical signs of infection, cultures were sent with special consideration to fungal infection. Results Two of the patients undergoing pancreas transplantation (one of whom died from disseminated candidiasis), three of the kidney transplant patients (two on the wound, one in the catheter), three patients with HIV (two on bile culture, one in the bloodstream) and one of the patients undergoing pancreatic resection (pancreatic fistula and bloodstream) had fungal infection. All patients had concomitant bacterial infections at the time of fungal infection (60 per cent Staphylococcus epidermidis). Patients with fungal infection had increased levels of immunosuppression with decreased CD4 recounts (pancreas transplants and patients with HIV), increased perioperative levels of blood glucose requiring insulin treatment, prolonged antibiotic therapy with broad-spectrum antibiotics (piperacillin–tazobactam), previous positive cultures from the bile of the biliary tract or the duodenum of the transplanted pancreas, and concomitant bacterial infections (especially opportunistic). Conclusion Surgical patients with positive cultures from surgical specimens, prolonged broad-spectrum antibiotic therapy and severely decreased lymphocyte immune function had an increased incidence of fungal infection with significant morbidity and mortality rates. Fungal prophylaxis is strongly recommended in these high-risk patients undergoing biliopancreatic tract surgery.
