Incidence and risk factors for hospital-acquired pneumonia after surgery for gastric cancer: results of prospective surveillance.
ABSTRACT Postoperative hospital-acquired pneumonia (HAP) is recognized as a major risk associated with surgery. Although upper abdominal surgery is known to have the highest incidence of postoperative HAP, little is known about the risk factors that contribute to HAP after gastric cancer surgery. The aim of this study was to determine the incidence and risk factors for HAP after elective surgery for gastric cancer.
We conducted prospective surveillance of all elective gastric resections by surgeons in ten affiliated hospitals, including ours, from May 2001 to May 2005. The outcome of interest was postoperative HAP. Univariate and multivariate analyses were performed to determine the predictive significance of variables in gastric cancer surgery.
A total of 529 patients undergoing elective operations for gastric cancer were admitted to the program. Postoperative HAP was identified in 20 patients (3.6%). Univariate and multivariate analyses showed that male gender and intra- and/or postoperative blood transfusion were independently predictive of postoperative HAP.
Male gender and intra- and/or postoperative blood transfusion were independent risk factors for the development of HAP after elective resection of gastric cancer. Surgeons should keep these risk factors in mind when managing postoperative patients.

ABSTRACT: BACKGROUND: Approximately 1.7 million individuals per year are affected with health care-associated infections (HAIs) in the United States. The authors examined trends in the incidence of HAI after major cancer surgery (MCS) and risk factors for HAI to describe the effects of HAI on mortality after MCS. METHODS: Patients undergoing 1 of 8 MCS procedures within the Nationwide Inpatient Sample between 1999 and 2009 were identified (n = 2,502,686). Generalized linear regression models were used to estimate the impact of the primary predictors (procedure type, age, sex, race, insurance status, Charlson comorbidity index, hospital volume, and hospital bed size) on the odds of HAI and in-hospital mortality. Trends in incidence were evaluated with linear regression. RESULTS: Overall, MCS-associated HAI incidence increased 2.7% per year (P < .001), whereas mortality decreased 1.3% per year (P < .001). Male gender (odds ratio [OR], 1.12, 95% confidence interval [CI], 1.10-1.14), advancing age (OR, 1.02; 95% CI, 1.02-1.02), black race (OR, 1.26; 95% CI, 1.21-1.31), ≥1 comorbidities (OR, from 1.08 [95% CI, 1.04-1.13] to 1.31 [95% CI, 1.27-1.35]), and nonprivate insurance (OR, from 1.18 [95% CI, 1.15-1.22] to 1.67 [95% CI, 1.59-1.76]) were associated with an increased odds of HAI on multivariable analysis. Conversely, increasing hospital volume was associated with lower odds of HAI (OR, 0.999; 95% CI, 0.99-0.99). Patients with MCS-associated HAI had increased odds of mortality (OR, 8.66; 95% CI, 8.51-8.82). CONCLUSIONS: Between 1999 and 2009, the incidence of MCS-associated HAI events increased; however, HAI-associated mortality decreased. That said, significant disparities exist in the hospital and demographic attributes associated with MCS-associated HAI, with attendant health policy implications. Moreover, HAI remains detrimentally linked to mortality during hospitalization. Cancer 2013;. © 2013 American Cancer Society.Cancer 03/2013; · 5.20 Impact Factor

ABSTRACT: Surgical treatment of gastric cancer has risks, and the current trend in developed countries is to centralize cases in high-volume centers. Many countries, however, particularly the developing ones, have to rely in low-volume centers for the most part of gastric cancer operations. We aimed to verify the characteristics of the patients and tumors as well as the in-hospital outcomes in a community hospital in Brazil treating gastric cancer. This is a retrospective study on patients undergoing surgical treatment of gastric adenocarcinoma at a community hospital in Brazil. The authors reviewed demographic, clinical, pathological, and perioperative data. A total of 28 patients were operated on during the study period. Mean age was 69.5 years, 53.6 % were male, 67.9 % had anemia, 78.5 % had ASA score ≥ 3, 89.3 % were at nutritional risk, intestinal/diffuse ratio was 1.6, 68.5 % had tumor ≥ 6 cm, involvement of lower/middle third of the stomach occurred in 96.4 %, 73.7 % had serosal invasion, 79 % had stage III disease, median number of dissected nodes was 23, median operative time was 255 min, 21.4 % had urgent procedures, 67.8 % had curative surgery, 50 % had distal gastrectomy, 43.5 % had a Billroth I, median length of stay was 17 days, 53.6 % had some admission to the intensive care unit, 21.4 % required relaparotomy, 25 % had wound infection/dehiscence, and mortality was 66.7/18.2 % (urgent/non-urgent surgery). We treat elderly malnourished patients with multiple comorbidities and advanced cancer. Improvement is required in lymph node dissection, non-surgical therapies, and critical care.Journal of Gastrointestinal Cancer 06/2013; 44(4).

ABSTRACT: Abstract Background: Post-operative pulmonary complications (PPCs) negatively affect patients' quality of life and can be life-threatening. Predictors of PPCs have been evaluated in patients who underwent various operations, but few studies have specifically focused on gastrectomy. Methods: We retrospectively studied 1,053 patients with gastric adenocarcinoma who underwent radical gastrectomy with lymphadenectomy in our hospital between 1999 and 2011. Post-operative pulmonary complications were defined as conditions such as pneumonia, macroscopic atelectasis, pneumothorax, and acute respiratory distress syndrome that developed within 30 d after surgery. We evaluated the relations between PPCs and pre-operative or intra-operative factors and assessed risk factors for PPCs after gastrectomy. Result: A total of 49 (4.7%) patients had PPCs. On univariate analysis, PPCs were significantly associated with male gender (p=0.024), predicted vital capacity (VC) (p=0.020), a lower pre-operative serum albumin concentration (p=0.023), open surgery (p=0.007), total gastrectomy (p<0.001), combined resection of another organ (p=0.001), extended operating time (p<0.001), higher operative bleeding volume (p<0.001), intra-operative or post-operative blood transfusion (p=0.009), and pathologic tumor stage (p=0.003). On multivariable analysis, extended operating time (odds ratio [OR], 3.21, 95% confidence interval [CI] 1.46-7.07; p=0.004), total gastrectomy (OR, 2.65, 95% CI 1.25-5.59; p=0.011) and predicted VC (OR, 2.42, 95% CI 1.01-5.85; p=0.049) were independent risk factors. These three factors also were independent risk factors for post-operative pneumonia (total gastrectomy OR, 2.64, 95% CI 1.32-5.30; p=0.006); extended operating time OR, 2.54, 95% CI 1.24-5.19; p=0.011; and predicted VC OR, 2.41, 95% CI 1.01-5.75; p=0.048). Conclusion: Extended operating time, total gastrectomy, and predicted VC were independent predictors of PPCs, particularly pneumonia, in patients with gastric cancer who underwent gastrectomy. In patients with restrictive pulmonary dysfunction who are scheduled to undergo total gastrectomy, reduced lymphadenectomy or the avoidance of combined resection should be considered to shorten the operating time.Surgical Infections 05/2014; · 1.72 Impact Factor
