Early postoperative hyperglycaemia is not a risk factor for infectious complications and prolonged in-hospital stay in patients undergoing oesophagectomy: a retrospective analysis of a prospective trial

INTRODUCTION: Treating hyperglycaemia in hospitalized patients has proven to be beneficial, particularly in those with obstructive vascular disease. In a cohort of patients undergoing resection for oesophageal carcinoma (a group of patients with severe surgical stress but a low prevalence of vascular disease), we investigated whether early postoperative hyperglycaemia is associated with increased incidence of infectious complications and prolonged in-hospital stay. METHODS: Postoperative glucose values up to 48 hours after surgery were retrieved for 151 patients with American Society of Anesthesiologists class I or II who had been previously included in a randomized trial conducted in a tertiary referral hospital. Multivariate regression analysis was used to define the independent contribution of possible risk factors selected by univariate analysis. RESULTS: In univariate regression analysis, postoperative glucose levels were associated with increased length of in-hospital stay (P < 0.001) but not with infectious complications (P = 0.21). However, postoperative glucose concentration was not found to be an independent risk factor for prolonged in-hospital stay in multivariate analysis (P = 0.20). CONCLUSION: Our data indicate that postoperative hyperglycaemia is more likely to be a risk marker than a risk factor in patients undergoing highly invasive surgery for oesophageal cancer. We hypothesize that patients with a low prevalence of vascular disease may benefit less from intensive insulin therapy

Graft dilatation and Barrett's esophagus in adults after gastric pull-up and jejunal interposition for long-gap esophageal atresia

BACKGROUND: Esophageal replacement (ER) with gastric pull-up (GPU) or jejunal interposition (JI) used to be the standard treatment for long-gap esophageal atresia (LGEA). Changes of the ER grafts on a macro- and microscopic level however, are unknown. AIM: To evaluate long-term clinical symptoms and anatomical and mucosal changes in adolescents and adults after ER for LGEA. METHODS: A cohort study was conducted including all LGEA patients ≥ 16 years who had undergone GPU or JI between 1985-2003 at two tertiary referral centers in the Netherlands. Patients underwent clinical assessment, contrast study and endoscopy with biopsy. Data was collected prospectively. Group differences between JI and GPU patients, and associations between different outcome measures were assessed using the Fisher's exact test for bivariate variables and the Mann-Whitney U-test for continuous variables. Differences with a P-value < 0.05 were considered statistically significant. RESULTS: Nine GPU patients and eleven JI patients were included. Median age at follow-up was 21.5 years and 24.4 years, respectively. Reflux was reported in six GPU patients (67%) vs four JI patients (36%) ( P = 0.37). Dysphagia symptoms were reported in 64% of JI patients, compared to 22% of GPU patients ( P = 0.09). Contrast studies showed dilatation of the jejunal graft in six patients (55%) and graft lengthening in four of these six patients. Endoscopy revealed columnar-lined esophagus in three GPU patients (33%) and intestinal metaplasia was histologically confirmed in two patients (22%). No association was found between reflux symptoms and macroscopic anomalies or intestinal metaplasia. Three GPU patients (33%) experienced severe feeding problems vs none in the JI group. The median body mass index of JI patients was 20.9 kg/m 2 vs 19.5 kg/m 2 in GPU patients ( P = 0.08). CONCLUSION: The majority of GPU patients had reflux and intestinal metaplasia in 22%. The majority of JI patients had dysphagia and a dilated graft. Follow-up after ER for LGEA is essential

Jejunoileal atresia and cystic fibrosis: don’t miss it

Abstract Background While an increased prevalence of cystic fibrosis (CF) in patients with jejunal atresia and ileal atresia (JIA) has been described previously, it still may not be a practice routine to indicate a sweat test or DNA test for CFTR mutations in newborns presenting with JIA. Leading textbooks do not mention JIA as a possible presenting clinical feature of CF. We describe two cases of JIA with a delayed diagnosis of CF (4 months [post mortem] and 19 months). This led to a retrospective review of all patients with JIA in our hospital. We hypothesised that also in the past although indicated further testing for CF had not always been performed. Methods Over an 18-year period from January 1991 until December 2008, all cases of JIA in our centre were reviewed (n=50). We compared patients who have been tested for CF (n=18) with patients who have not been tested for CF (n=32), with respect to their patient characteristics, either by logistic regression analysis or a nonparametric test (p Results Of all 50 patients the proportion of infants actually tested for CF was 18 (36%). A statistical significant difference between the group of patients who were tested for CF versus the group of those who were not tested was found in a higher occurrence of postoperative bilious retention after 7 days (56% versus 25%, respectively), and postoperative complications (78% versus 34%, respectively). CF was confirmed in 4 (8%). Conclusion Testing for CF in newborns presenting with JIA does not appear to be common practice. A timely diagnosis of CF leads to presymptomatic treatment and has beneficial effects on morbidity and mortality. CF should be tested for in all children with JIA. We recommend a sweat test for term children and CFTR DNA testing as a first step for preterm infants. Medical professional awareness may be increased if future editions of leading text books in the relevant fields should include JIA as an indication to follow an appropriate CF-diagnostic algorithm.

Ischemia modified albumin as a marker of hypoxia in preterm infants in the first week after birth

Background: Tissue hypoxia remains a leading cause of morbidity and mortality in preterm infants. Current biomarkers often detect irreversible hypoxic cellular injury (i.e. lactate) and are non-specific. A new biomarker is needed which detects tissue hypoxia before irreversible damage occurs. Aims: To investigate the relation between serum ischemia modified albumin (IMA), a marker of hypoxia; and analytic variables, patient related variables and conditions associated with hypoxia, in preterm infants. Study design: Retrospective cohort study. Subjects: Infants with a gestational age < 30 weeks and/or birth weight < 1000 g. Outcome measures: We collected two remnant blood samples in the first week after birth and measured IMA. IMA/albumin ratio (IMAR) was used to adjust for albumin. We assessed correlations between IMA(R) and analytic variables (albumin, lipemia- and haemolysis index); mean-2 h SpO2; mean-2 h variability of regional splanchnic oxygen saturation (rsSO2), measured using near-infrared spectroscopy; and patent ductus arteriosus (PDA). Results: Sixty-five infants were included. Albumin, the lipemia- and haemolysis index correlated negatively with IMA (r:-0.620, P<0.001; r:-0.458, P<0.001; and r:-0.337, P=0.002). IMAR correlated negatively with SpO2 (rho:-0.614, P<0.001). Lower rsSO2 variability correlated with higher IMAR values (rho:-0.785, n=14, P=0.001 and rho:-0.773, n=11, P=0.005). Infants with a hemodynamic significant PDA (hsPDA) had higher IMAR values than infants without PDA (0.13 [0.11–0.28], n=16 vs. 0.11 [0.08–0.20], n=29, P=0.005 and 0.11 [0.09–0.18], n=13 vs. 0.09 [0.06–0.17], n=37, P=0.026). Conclusions: When adjusted for albumin, the lipemia- and haemolysis index, IMAR has potential value as a marker for systemic hypoxia in preterm infants, considering the associations with SpO2, variability of rsSO2, and hsPDA
