Background: The incidence of postoperative fungal infection is increasing and the gastrointestinal tract is the major source, but antifungal therapy in perforated peptic ulcer (PPU) is still controversial. The aim of this study was to determine the significance of intraoperative peritoneal fluid culture of fungus and establish the indications for treatment., Methods: Between July 1997 and September 2001, all patients admitted with a PPU were studied. Clinical data and peritoneal fluid for culture were collected. Risk factors for a positive peritoneal fluid culture of fungus and outcome were evaluated, and related to the development of surgical site infection, duration of hospital stay and mortality rate., Results: One hundred and forty-five patients with a PPU were included; 63 (43.4 per cent) had positive peritoneal fluid fungal culture. Age, preoperative organ failure, delay in operation, high Mannheim Peritonitis Index (MPI) and Acute Physiology And Chronic Health Evaluation (APACHE) II scores, and preoperative antibiotic therapy were risk factors for a positive fungal culture. Sex and an MPI score of 20 or more remained significant in multivariate analysis (P < 0.001). Patients with a positive fungal culture had a higher incidence of surgical site infection, a longer hospital stay and a significantly higher mortality rate, especially when this was combined with a high MPI score., Conclusion: Positive peritoneal fungal culture was common and was a significant risk factor for adverse outcome in patients with a PPU. A high MPI score could be used as an indicator for prophylactic antifungal therapy., (Copyright 2003 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.)

Chyloperitoneum is rare condition that can occur in response to various pathologic process. The authors described a newborn baby who had chyloperitoneum after primary surgical repair of esophageal atresia with tracheoesophageal fistula (Gross type C). This probably resulted from iatrogenic damage of the thoracic duct during ligation of azygous vein resulting in leaking lacteal within the intestinal wall. Biochemical analysis of ascitic fluid, plasma, and milk formula for triglyceride and cholesterol level can differentiate neonatal gastric intestinal perforation., (Copyright 2001 by W.B.
