Comparison of Laparoscopic-Assisted Operations and Laparotomy Operations for the Treatment of Hirschsprung Disease: Evidence From a Meta-Analysis

The purpose of this meta-analysis is to compare the relative merits among laparoscopic-assisted operations and laparotomy operations for patients with Hirschsprung disease.PubMed, Web of Science, and Wanfang databases were searched for the related articles. We analyzed dichotomous variables by estimating odds ratios (ORs) with their 95% confidence intervals (CIs) and continuous variables using the weighted mean difference (WMD) with the 95% CI. The random-effects model (REM) was used to combine the results. The outcome measures included operating time (OT), estimated blood loss (EBL), length of hospital stay (LOHS), mean first bowel movement (MFBM), and number of complications.Sixteen articles were included in the meta-analysis. These studies involved a total of 774 patients, 396 of whom underwent laparoscopic-assisted operations and 378 of whom underwent laparotomy operations. The EBL (WMD = −1.48, 95% CI = −1.82, −1.13), LOHS (WMD = −0.67, 95% CI = −0.86, −0.49), MFBM (WMD = −0.83, 95% CI = −1.05, −0.61), and number of complications (OR = 0.60, 95% CI = 0.40, 0.89) were significantly lower in laparoscopic-assisted operations than in laparotomy operations. The OT (WMD = 0.12, 95% CI = −0.05, 0.28) showed no significant differences between laparoscopic-assisted operations and laparotomy operations.Compared with laparotomy operations, laparoscopic-assisted operations are generally safer and more reliable for patients with Hirschsprung disease.

效应室浓度作为目标浓度靶控输注异丙酚的脑摄取研究

OBJECTIVE: To study the correlation between the effect compartment concentration (ECC) and the brain uptake of propofol during sedation by target-controlled infusion (TCI). METHOD: Twelve ASA physical status I to II patients with neither cardiac nor intracranial diseases were scheduled for elective abdominal operation. Computer-assisted target-controlled infusion of propofol was performed for general anesthesia in all patients with the target ECC set at 4.0 microgram/ml. The plasma propofol concentrations were measured simultaneously from the radial artery and the jugular bulb at different time points by high performance liquid chromatography (HPLC), and the area under time-concentration curve (AUC(a-jv)) was calculated. RESULT: Before reaching the target propofol concentration of 4.0 microgram/ml (4.7+/-0.16 min), EEC was positively correlated with AUC(a-jv) (r(ECC-AUC)=0.977, P<0.001), but neither the arterial (Ca) nor jugular bulb propofol concentrations (Cjbv) showed such relation to AUC(a-jv) (r(Ca-AUC)= 0.054, P=0.92; r(Cjbv-AUC)=0.335, P=0.516). When ECC was controlled at 4.00 microgram/ml by TCI, Ca was comparable with Cjbv (P=0.512). Positive correlation was noted between AUCa-jv and ECC (r(ECC-AUC)=0.942, P<0.005) after the termination of infusion till the consciousness recovery of the patients, and Ca and Cjbv showed similar correlation with AUC(a-jv) (r(Ca-AUC)=0.986, P<0.001; r(Cjbv-AUC)=0.974, P<0.001). CONCLUSION: During TCI of propofol with ECC as the target concentration, ECC is significantly correlated with AUC(a-jv) to reflect the dynamic changes in cerebral propofol uptake.

Growth hormone effects on hypertrophic scar formation: a randomized controlled trial of 62 burned children

The hypercatabolism after massive pediatric burns has been effectively treated with recombinant human growth hormone, an anabolic agent that stimulates protein synthesis and abrogates growth arrest. While experimental studies have shown increased potential for fibrosis induced by growth hormone therapy, adverse effects on human scars have not been investigated. Our aim was to evaluate hypertrophic scar formation in 62 patients randomized to receive injections of 0.05 mg/kg/day of recombinant human growth hormone or placebo, from discharge until 1 year after burn. Scar scales were used to evaluate scar-severity at discharge, 6, 9, 12, and 18-24 months after burn, by three observers blinded to treatment. Computer-assisted planimetry allowed quantification of percentage of hypertrophic scar formation. Types I and III collagens were localized and quantified in scars and normal skin of patients from both groups, using immunohistochemistry with confocal laser microscopy analysis. Insulin-like growth factor-1 blood levels helped assess compliance. Statistical analysis showed that scar hypertrophy significantly increased from 6 to 12 months after injury in both groups, while decreasing at 18-24 months postburn. Types I and III collagens were statistically increased in the reticular layer of scars from both groups when compared to paired normal skin. Insulin-like growth factor-1 was significantly increased in the recombinant human growth factor-treated group. No differences were seen when recombinant human growth factor and control groups were compared using the scar scales, planimetry, or immunohistochemistry. We concluded that recombinant human growth hormone therapy did not adversely affect scar formation and should not contraindicate the administration of recombinant human growth hormone as a therapeutic approach to severely burned children.
