RESUMO
PURPOSE: To analyze the impact of postoperative remote infections (PRIs) on medical expenditure. METHODS: The subjects of this retrospective study were 338 patients who had undergone gastroenterological surgery at one of the 20 Japanese institutions within the Japan Society for Surgical Infection (JSSI) and mainly authorized as educational institutions. The patients were allocated to 169 pairs of those with a PRI (PRI (+) group) matched with those without a PRI (PRI (-) group). PRIs included pneumonia, urinary tract infection (UTI), catheter-associated blood stream infection (CA-BSI), and antibiotic-associated enteritis. RESULTS: SSI developed in 74 of the 338 patients (22 without PRI and 52 with PRI). The SSI incidence was significantly higher in the PRI (+) group (p < 0.001). The difference in the median postoperative length of hospital stay was 15 days, indicating a significant prolongation in the PRI (+) group (p < 0.001). The PRI (+) group also had a higher rate of inter-hospital transfer (p < 0.01) and mortality (p < 0.001). Similarly, the difference in median postoperative medical fees was $6832.3, representing a significant increase in the PRI (+) group (p < 0.001). CONCLUSIONS: The postoperative length of hospital stay is longer and the postoperative medical expenditure is higher for patients with a PRI than for those without a PRI.

PURPOSE: To investigate changes in the incidence of postoperative infections in the surgical department of a teaching hospital. METHODS: During the 30-year period from September 1987 to August 2017, 11,568 gastroenterological surgical procedures were performed in our surgical department. This 30-year period was divided into seven periods (A-G), ranging from 2 to 7 years each and based on the infection control methods used in each period. We then compared the rates of incisional surgical site infection (SSI) and organ/space SSI; remote infection (RI) including respiratory tract infection (RTI), intravascular catheter-related infection, and urinary tract infection (UTI); and antibiotic-associated colitis caused by methicillin-resistant Staphylococcus aureus (MRSA) enteritis or Clostridioides (Clostridium) difficile-associated disease (CDAD) among the seven periods. RESULTS: In periods B (September 1990-August 1997) and E (November 2004-July 2007), when a unique antibiotic therapy devised in our department was in use, MRSA was isolated from only 0.3% and 0.4% of surgical patients, respectively, and these rates were significantly lower than those in the other periods (p < 0.05). The rate of CDAD increased during period F (August 2007-July 2014), but in period G (August 2014-August 2017), restrictions were placed on the use of antibiotics with a strong anti-anaerobic action and, in this period, the rate of CDAD was only 0.04%, which was significantly lower than that in period F (p < 0.05). CONCLUSIONS: Limiting the use of antibiotics that tend to disrupt the intestinal flora may reduce the rates of MRSA infection and CDAD after gastroenterological surgery.

BACKGROUND: Postoperative infections can be classified as surgical site infections and remote infections. Postoperative respiratory tract infections (PRTI) are a type of remote infection and may be associated with prolonged hospitalization and increased medical expenses. This study compared postoperative duration of hospitalization and medical expenses between patients with and without PRTI after gastrointestinal surgery. METHODS: We retrospectively analyzed data from a multicenter study of centers affiliated with the Japan Society for Surgical Infection and used 1-to-1 matching analysis to evaluate 86 patients who underwent gastrointestinal surgery during the period from March 1, 2014 through February 29, 2016. RESULTS: Duration of postoperative hospitalization was significantly longer for patients with PRTI (38.6 days) than for those without PRTI (16.1 days), and postoperative medical expenses were significantly higher for patients with PRTI (1388.2 USD) than for those without PRTI (629.4 USD). CONCLUSIONS: Duration of hospitalization is longer and medical expenses are higher for patients that develop surgical site infections. This study found that this was also the case for patients with PRTI after gastrointestinal surgery. However, further studies are needed in order to confirm these results.

BACKGROUND: The origin of moisture in diarrhea feces is unknown but may represent the unabsorbed part of intestinal contents or alternatively, body fluid excreted into the digestive canal. If the latter mechanism contributes to moisture in the feces, active transport of water (H2O) associated with ion exchange channels may be involved. OBJECTIVE: To investigate this possibility we measured the content of moisture and minerals (sodium [Na], potassium [K], calcium [Ca], magnesium [Mg], phosphorus [P], zinc [Zn], iron [Fe], copper [Cu] and manganese [Mn]) in feces collected during a 12-d metabolic study on 11 young Japanese female students. DESIGN: The study was carried out as part of a human mineral balance study. The same quantity of food was supplied to each of the subjects throughout the study without consideration of body weight. Fecal specimens were collected throughout the study and were separated into those originating from the diet during the balance period based on the appearance of the ingested colored marker in the feces. RESULTS: The moisture content of the feces ranged between 53 and 92%. Na content in the feces was low and stable when the moisture content was below 80%, whereas it increased up to serum levels when the moisture content increased above 80%. On the other hand, K content increased when compared to dry matter base. However, when comparing concentration/g moisture, K content increased when moisture was below 70%, but decreased when this rose above 70%.
