Background
Traditionally, a stoma is established after resection of perforated or necrotic intestine for isolated intestinal perforation (IIP) and necrotizing enterocolitis (NEC). We compared the outcome of resection and anastomosis (RA) with stoma formation (RS).Methods
Sixty-eight neonates undergoing laparotomy for IIP (n = 20), NEC (n = 43), and indeterminate cause (n = 5) were reviewed retrospectively. Intestinal resection was followed by either anastomosis or stoma. The primary outcome measure was the frequency of anastomosis- and stoma-related complications.Results
The median gestational age (GA) was 28.5 weeks and birth weight (BW) was 940 g. Thirty-seven neonates had RA (NEC 22, IIP 14, 1 unknown), 28 RS (NEC 21, IIP 6, 1 unknown), and 3 laparotomy only. Twenty-five neonates died postoperatively. The mean ± SD GA of those who survived was 30 ± 4.5 weeks and those who died was 27.2 ± 3.5 weeks (P = .008). The mean BW for those that survived was 1440.5 ± 865.1 g and those who died was 827.7 ± 385.1 g (P = .002). There was no statistically significant difference between the RA and RS groups for GA (P = .93), BW (P = .4), general complications (P = .96), anastomosis and stoma complications (P = .48), and deaths (P = .42).Conclusions
RA, rather than stoma, is an acceptable option in the surgical management of preterm neonates with IIP or NEC. 相似文献2.

Aim
The aim of the study was to evaluate the morbidity rate of stoma in children diagnosed with chronic intestinal pseudoobstruction (CIPO) and try to determine risk factors.Material and Methods
Twenty-two children (65%) of 34 referred to our center between 1988 and 2008 had a stoma. They were compared with 22 other children referred for another pathology necessitating a stoma.Results
The incidence of stomal prolapse in CIPO children was 45% vs 9% in non-CIPO children (P = .01). Prolapse occurred between the first postoperative day and the 10th postoperative month, with a median of 2 months. Surgical management was required in 60%, with an intestinal necrosis rate of 20% leading to intestinal resection. No mortality was noted. No risk factors favoring prolapse in CIPO children were identified.Conclusion
Children with CIPO have a high rate of stomal prolapse with an increased risk of intestinal necrosis. Careful management of the stoma is necessary to avoid the risk of intestinal resection, which may aggravate the underlying intestinal disorder. 相似文献3.

Background
Ostomy reversal is considered a contaminated surgery and, thus, primary closure is believed to increase infection. Various closure techniques have been described and postulated to be superior to primary closure in regards to decreasing stoma site wound infections. The literature has varied in its support for this hypothesis.Methods
A retrospective review was performed evaluating several variables including stomal closure method, patient demographics, steroid/immunosuppressant use, chemotherapy or radiation, perioperative antibiotics, and surgical indication to determine whether there was any association with the development of wound infections.Results
Of 75 patients undergoing ostomy reversal, delayed primary closure/packing/secondary intention was used in 49 (65%), and 26 underwent primary closure (35%). Four patients (5.3%) developed stoma site infections; all had delayed primary closure or packing of their wound (P = .39). No variable was associated significantly with an increased risk of stoma site wound infections.Conclusions
Primary closure does not increase the rate of infection. 相似文献4.

Objectives
Small bowel perforations in the neonatal period can be secondary to necrotizing enterocolitis (NEC), ischemic necrosis, or occlusive anomalies of the small bowel; furthermore, they may be of no discernible cause. Depending on the clinical condition of the infant and the extent of the disease, a number of surgical options are available; one of which is exteriorization. To reduce the morbidity of stoma among patients, we adopted a technique called window enterostomy (WEnt). The objectives of this study were to describe the technique and to compare WEnt with conventional enterostomy (CEnt) in preterm infants undergoing surgery for focal NEC or isolated small bowel perforation (ISBP).Methods
We reviewed all cases of NEC and ISBP between January 1996 and March 2006 from our institution. Patients with focal NEC or ISBP who required a surgical intervention were included and categorized into the WEnt and the CEnt groups. We collected multiple data as study variables: demographics; site of perforation; operative time; need for a second operation; postoperative morbidity; duration of total parenteral nutrition; and postoperative weight gain.Results
Twenty-four neonates met the criteria for study inclusion. Of these, 14 underwent CEnt and 10 underwent WEnt. The median gestational age and birth weight of the neonates were 25.4 weeks (SD = 1.4) and 814.4 g (SD = 195.1), respectively. In comparing the 2 groups, we found statistically significant differences in the operative time for the primary and secondary procedures, duration of total parenteral nutrition, time to full oral feeding, and weekly postoperative weight gain. The rate of postoperative complications was higher among the infants from the CEnt group.Conclusion
Our results suggest that WEnt is a quick and workable technique with minimal morbidity for preterm neonates with focal NEC or ISBP. 相似文献5.

Background
Surgical site infections cause significant postoperative morbidity and may be reduced by pressurized irrigation of high-risk laparotomy wounds before closure. This was a retrospective review (June 2007 to May 2008) from a surgical unit at a tertiary care center.Methods
Patients undergoing laparotomy extending beyond 4 hours, when a standard wound management strategy was instituted by either simple irrigation or pressurized pulsatile lavage (<15 psi) with saline before closure, were included. The outcome measures were the surgical site infections and factors contributing to them.Results
The median surgical time for the patients was 8 hours, with 34 wounds managed by simple irrigation and 42 wounds managed by pulse irrigation. Both groups had similar characteristics. Overall there were 15 (20%) surgical site infections. Significantly fewer infections occurred in the pulse irrigation group (10% vs 32%; P = .019). The use of a pulse irrigation device was the only factor associated with a reduction in wound infections (P = .019).Conclusions
Surgical site infections appear to be reduced with pulsatile lavage irrigation of wounds before skin closure in patients undergoing prolonged intra-abdominal surgeries. 相似文献6.

Background
The Malone antegrade continence enema (MACE) procedure has been previously described as a safe and effective option for the treatment of children with chronic defecation disorders when maximal medical therapy and conventional treatment have failed.Purpose
To evaluate clinical success, complications, and quality of life of children with chronic defecation disorders with a MACE stoma.Methods
A retrospective analysis of 23 patients who underwent the construction of a MACE stoma was performed. Preoperative and postoperative data were evaluated. A specific questionnaire was used to assess patient satisfaction.Results
A significant increase was found in defecation frequency (1.0 [range, 0-4] pretreatment vs 5.5 [range, 0-28] posttreatment per week; P < .006) and a significant decrease in fecal incontinence frequency (10 [range, 0-14] pretreatment vs 0 [range, 0-14] posttreatment per week; P < .034). Postoperative complications of the MACE procedure were fecal leakage (43%), wound infection (52%), and stomal stenosis (39%). A total of 86% of the patients were satisfied with the results of the Malone stoma (n = 21).Conclusions
The MACE procedure is an effective treatment in children with intractable defecation disorders. Postoperative complications are, however, not uncommon. Further refinement of the technique focused to reduce the complication rate is necessary to expand the application of this approach. 相似文献7.

Objective
To identify factors associated with survival in patients with congenital diaphragmatic hernia (CDH) treated with extracorporeal membrane oxygenation (ECMO).Methods
We retrospectively analyzed the data on 3100 patients with CDH in the Congenital Diaphragmatic Hernia Study Group from 82 participating pediatric surgical centers (1995-2004). Covariates considered included prenatal and perinatal clinical information, specifics of surgical repair, and the duration of extracorporeal support.Result
Nine hundred seven patients from the registry were identified as having been both managed with ECMO and undergone attempted surgical repair. The survival rate for the entire Congenital Diaphragmatic Hernia Study Group registry was 67% and 61% for those receiving ECMO in whom repair was attempted (P < .001). Among ECMO-treated children, survivors had a greater estimated gestational age (38 ± 2 vs 37 ± 2 weeks; P < .01), greater birth weights (3.2 ± 0.5 vs 2.9 ± 0.5 kg; P < .001), were less often prenatally diagnosed (53% vs 63%; P < .01), and were on ECMO for a shorter period of time (9 ± 5 vs 12 ± 5 days; P < .001). In logistic regression models, therapy-related variables, including the duration of ECMO, the nature of diaphragmatic repair, and the type of abdominal closure and certain comorbidities, particularly the presence of a concomitant severe cardiac abnormality, were independently associated with outcome.Conclusion
Our model identifies a group of pre-surgical and postsurgical parameters that predict survival rate in patients with CDH on ECMO support. This model was derived from the retrospective data from a large database and will need to be prospectively tested. 相似文献8.
New technique for enterostomy of extremely low-birth-weight infants--intestinal anchoring with gauze
Kondo K Chijiiwa K Mukai M Iwamura T Matsuda H Kaneko M Kodama Y Sameshima H Ikenoue T 《Journal of pediatric surgery》2008,43(9):1755-1760
Background
In enterostomy for extremely low-birth-weight infants (<1000 g), the technique of anchoring the intestine for a stoma to the abdominal wall is very difficult because of the small size and fragile nature of the intestine. Here we describe a novel technique for intestinal anchoring in such infants.Methods
In our approach to enterostomy, the intestine is anchored only by a strip of gauze packed into the subcutaneous space. No suturing is performed. The efficacy of this technique was evaluated in 21 infants with less than 1000 g of body weight who have intestinal perforation or obstruction.Results
Two patients (9.5%) had complications that were related to the enterostomy. The complications were parastomal and intrastomal intestinal prolapse, both of which were treated successfully by reoperation. Eighteen patients (86%) survived to closure of the enterostoma.Conclusions
Intestinal anchoring with gauze is an easy and effective technique for enterostomy in extremely low-birth-weight infants and can be applied in selected cases. 相似文献9.
Background
Posttransplantation diabetes mellitus (PTDM) is a well-recognized renal transplantation complication that is associated with increased graft loss, morbidity, and mortality. Adiponectin gene polymorphisms are associated with type 2 diabetes. However, it remains unknown whether these polymorphisms increase the risk for development of PTDM. Therefore, the aim of this study was to investigate the association between the adiponectin gene polymorphism and the risk of PTDM among Chinese renal allograft recipients.Methods
We genotyped 398 unrelated renal allograft recipients without a prior diagnosis of diabetes, including 97 PTDM and 301 without PTDM, for adiponectin gene variants: single nucleotide polymorphisms at position 45 and 276, that is, SNP-45: T/G, SNP-276: G/T, using the polymerase chain reaction-restriction fragment length polymorphism assay. No prisoners or organs from prisoners were used in the study.Results
The G allele of SNP-276 was significantly more frequent in PTDM than non-PTDM subjects (P = .041). For SNP-45 and SNP-276, the incidence of PTDM was significantly higher in patients with the GG genotype than those with the TG and TT genotypes (48.1% vs 21.5% and 23.6% and 30.7% vs 18.5% and 22.8%; (P = .011 and .024, respectively). Even after adjusting for age and sex, the effects of the SNP-45 genotypes for GG compared to TT (odds ratio [OR] = 3.108, P = .009) and GG compared to TG (OR = 3.620, P = .004) as well as for SNP-276 genotypes GG compared to TG (OR = 2.203, P = .002) and body mass index at transplantation (OR = 1.099, P = .024) remained significant.Conclusions
These data suggested that SNP-45 and SNP-276 of the adiponectin gene were significantly associated with an increased risk for PTDM among Chinese renal allograft recipients. 相似文献10.

Purpose
Necrotizing enterocolitis (NEC) remains a major cause of morbidity and death in neonates. Evidence suggests that an imbalance between activated proinflammatory response with inadequate antiinflammatory protection results in NEC. Ozone has been proposed as an antioxidant enzyme activator, immunomodulator, and cellular metabolic activator. Therefore, this study was designed to investigate whether medical ozone therapy is effective on neonatal rat model of NEC.Materials and Methods
Thirty-eight newborn Sprague-Dawley pups were randomly divided into 3 groups of NEC, NEC + ozone, and control (left to breast feed). Necrotizing enterocolitis was induced by enteral formula feeding and exposure to 100% carbon dioxide inhalation for 10 minutes after +4°C cold exposures for 5 minutes and 97% oxygen for 5 minutes 2 times daily. The NEC + ozone group received 0.7 mg/kg per day ozone/oxygen mixture intraperitoneally for a total of 3 days after first day of NEC procedure. The pups were killed at fourth day, and their intestinal tissues were harvested for biochemical and histopathologic analysis. Blood sample from pups were also obtained.Results
The mortality rate and the weight loss were significantly higher in NEC group than control and treatment groups. Oxidative stress markers (malondialdehyde and protein carbonyl content) significantly increased and antioxidant enzyme activities (superoxide dismutase and glutathione peroxidase) were significantly decreased in NEC group. All these biochemical changes were ameliorated in NEC + ozone group. Nitrate plus nitrite levels and serum tumor necrosis factor α were elevated in NEC group and reduced in treatment group. In addition, histopathologic injury score of NEC group was significantly higher than NEC + ozone group.Conclusion
Ozone treatment significantly reduced the severity of NEC by modulating antioxidative defense and antiinflammatory protection in our experimental animal model. 相似文献11.

Purpose
Good outcomes have been reported with laparoscopic appendectomy (LA) for uncomplicated appendicitis in children, but the use of laparoscopy for complicated appendicitis in children is more controversial. This is related to a higher incidence of postoperative abdominal and wound infections. The purpose of this trial was to retrospectively compare LA and open appendectomy (OA) for complicated appendicitis and evaluate the efficacy of LA in children with complicated appendicitis.Methods
The outcome of 128 patients with complicated appendicitis in children was retrospectively analyzed. There were 80 children in the LA group and 48 in the OA group. The appendectomies were performed by a single senior surgeon and his surgical trainees. There was no selection of cases for LA. Data collection included demographics, operative time, resumption of diet, infectious complications (wound infection and intraabdominal abscess), length of hospitalization, and duration of antibiotic use.Results
There were no cases of LA that required conversion to OA. The operative time for LA (88.5 ± 28.8 minutes for LA vs 71.8 ± 30.6 minutes for OA; t = 3.10; P = .002) was longer. Patients in the LA group returned to oral intake earlier (1.8 ± 0.6 days for LA vs 2.8 ± 0.8 days for OA; t = −8.04; P < .01) and had a shorter length of hospital stay (6.5 ± 2.2 days for LA vs 7.8 ± 2.9 days for OA; t = −2.87; P = .005). The incidence of wound infection (1/80 [1.3%] for LA vs 6/48 [12.5%] for OA; P < .05) and postoperative intraabdominal abscess (2/80 [2.5%] for LA vs 7/48 [14.6%] for OA; P < .05) in LA group was lower. No significant difference was found in the duration of antibiotic administration between the 2 groups (5.8 ± 1.8 days for LA vs 6.3 ± 2.3 days for OA; t = −1.37; P = .174). No mortality was observed in either group.Conclusions
The minimally invasive laparoscopic technique is feasible, safe, and efficacious for children with complicated appendicitis. Laparoscopic appendectomy should be the initial procedure of choice for most cases of complicated appendicitis in children. 相似文献13.

Objective
To determine the prevalence of hyperhomocysteinemia (plasma homocysteine[Hcy] concentration ≥15 μmol/L) and evaluate its correlation with allograft function.Materials and Methods
The study included 159 stable renal transplant recipients (104men and 55 women). The prevalence and severity of hyperhomocysteinemia werecompared in the transplant recipients vs 72 patients (48 men and 24 women) receivinghemodialysis therapy.Results
The mean (SD; range) fasting total Hcy concentration was higher in thehemodialysis group compared with the renal transplantation group: 27.4 (18.3; 10-95)μmol/L vs 16.6 (9.5; 4.5-45.0) μmol/L (P = .00). Hyperhomocysteinemia occurred morefrequently in patients receiving hemodialysis therapy (74% vs 49%). No significantcorrelation was observed between Hcy concentration and recipient sex, cyclosporinetrough concentration and concentration at 2 days after dosing, dyslipidemia,cytomegalovirus infection, diabetes mellitus, or aspartate or alanine aminotransferaseconcentration. Multivariate regression analysis revealed that serum creatinineconcentration (P = .02) was the major determinant of increased total Hcy concentration inrenal transplant recipients.Conclusion
A high prevalence of moderate hyperhomocysteinemia was observed in renaltransplant recipients. There was no correlation between graft function and Hcyconcentration. 相似文献14.

Aim
The purpose of this study was to assess the effectiveness of routine staged reduction and closure at the bedside, using preformed silos with no general anesthesia (PSnoGA), compared to emergency operative fascial closure (OFC) under general anesthesia for gastroschisis (GS).Methods
A retrospective matched case-control analysis of neonates with GS was performed between 1990 and 2004 inclusively. Assessment included demographics, method of closure, days on ventilator, days to first enteral feed, days to full oral feeds, days on parenteral nutrition, length of hospital stay, and complications.Results
Sixty-five patients with GS were treated in our institution between 1990 and 2004. Thirty-five underwent OFC, 4 had Bianchi ward reduction, and 26 received PSnoGA. Seventeen patients with bowel perforation, atresia, ward reduction, medical complications necessitating ventilation, or any other condition requiring urgent surgical intervention were excluded from the analysis. Patients were well matched for gestation and birth weight. Forty-eight patients (OFC = 27 and PSnoGA = 21) were compared by using Mann-Whitney U test. Median days on ventilator (4 vs 0; P ≤ .0001) was significantly reduced, but there was no difference for days to full oral feeds (26 vs 31; P = .26), days on parenteral nutrition (25 vs 30; P = .28), and length of stay (32 vs 36; P = .32), respectively. Complications were similar for both groups.Conclusions
PSnoGA has outcomes statistically similar to OFC, although days on ventilator are significantly reduced. Slow reduction of the bowel avoids abdominal compartment syndrome and closure may be achieved without fascial sutures. PSnoGA is performed at the bedside and aims to avoid general anesthesia, a period of ventilation, and out-of-hours operating, thereby reducing costs. A prospective, multicenter, randomized control trial is needed to evaluate the effectiveness of PSnoGA. 相似文献15.
Purpose
We have previously demonstrated that enterally administered heparin-binding epidermal growth factor-like growth factor (HB-EGF) decreases the incidence and severity of necrotizing enterocolitis (NEC) in a neonatal rat model. Because apoptosis contributes to gut barrier failure in this model, the aim of this study was to investigate the effect of HB-EGF on apoptosis during the development of NEC.Methods
NEC was induced in neonatal rats by exposure to hypoxia, hypothermia, hypertonic formula feeding (HHHTF) plus enteral administration of lipopolysaccharide (LPS). Fifty-one neonatal rats were randomly divided into the following groups: (1) breast-fed (BF), (2) HHHTF + LPS, and (3) HHHTF + LPS with HB-EGF (600 μg/kg) added to the formula. NEC was evaluated using a standard histological scoring system. Apoptotic cells in intestinal tissues were detected by terminal deoxynucleotidyltransferase-mediated dUTP nick end labeling (TUNEL) and by active caspase 3 immunohistochemical staining.Results
The incidence of NEC in the HHHTF + LPS group was higher than that in the BF group (65% vs 0%, P < .05). With administration of HB-EGF, the incidence of NEC significantly decreased to 23.8% (P < .05). The median TUNEL and active caspase 3 scores in the HHHTF + LPS group were higher than those in the BF group (1.9 vs 0.9 and 1.75 vs 0.6, respectively, P < .05). The median TUNEL and active caspase 3 scores were significantly decreased in the HHHTF + LPS + HB-EGF group compared with the HHHTF + LPS group (1.24 vs 1.9 and 1.0 vs 1.75, respectively, P < .05).Conclusion
HB-EGF reduces the incidence of NEC in a neonatal rat model in part by decreasing apoptosis. These results support the use of HB-EGF-based clinical regimens for the treatment of NEC. 相似文献16.

Background
Necrotizing enterocolitis (NEC) is the leading surgical cause of death in premature infants. We have accumulated evidence supporting a role for heparin-binding epidermal growth factor (EGF)-like growth factor (HB-EGF) in protection of the intestines from NEC. The aim of the current study was to evaluate the effect of loss-of-function of endogenous HB-EGF on susceptibility to NEC.Methods
Neonatal HB-EGF(−/−) knockout (KO) mice and their HB-EGF(+/+) wild-type (WT) counterparts were exposed to experimental NEC. An additional group of HB-EGF KO pups were also exposed to NEC but had HB-EGF added to their formula. To examine gut barrier function, HB-EGF KO and WT pups received intragastric fluorescein isothiocyanate-labeled dextran (FITC dextran) under basal and stressed conditions, and serum FITC dextran levels were measured.Results
The WT mice had an incidence of NEC of 53%, whereas HB-EGF KO mice had a significantly increased incidence of NEC of 80% (P = .04). Importantly, administration of exogenous HB-EGF to HB-EGF KO pups significantly reduced the incidence of NEC to 45% (P = .04). Heparin-binding EGF KO mice had significantly increased intestinal permeability compared to WT mice under basal and stressed conditions.Conclusions
Our results provide evidence that loss of the HB-EGF gene increases susceptibility to NEC and that administration of exogenous HB-EGF reverses this susceptibility. 相似文献17.
Purpose
Very low birth weight infants (VLBWIs) are at risk of surgical intestinal disorders including necrotizing enterocolitis (NEC), focal intestinal perforation (FIP), and meconium-related ileus (MRI). We conducted this study to verify whether the timing of stoma closure and that of enteral nutrition establishment after stoma closure in VLBWIs differ among the most common disorders.Methods
A retrospective multicenter study was conducted at 11 institutes. We reviewed the timing of stoma closure and enteral nutrition establishment in VLBWIs who underwent stoma creation for intestinal disorders.Results
We reviewed the medical records of 73 infants: 21 with NEC, 24 with FIP, and 25 with MRI. The postnatal age at stoma closure was 107 (28–359) days for NEC, 97 (25–302) days for FIP, and 101 (15–264) days for MRI (p?=?0.793), and the postnatal age at establishment of enteral nutrition was 129 (42–381) days for NEC, 117 (41–325) days for FIP, and 128 (25–308) days for MRI (p?=?0.855). The body weights at stoma closure were 1768 (620–3869) g for NEC, 1669 (1100–3040) g for FIP, and 1632 (940–3776) g (p?=?0.614) for MRI. There were no significant differences among the three groups.Conclusions
The present study revealed that the time and body weights at stoma closure and the postoperative restoration of bowel function in VLBWIs did not differ among the three diseases.18.

Study Objective
To evaluate the effect of clonidine when added to local anesthetics on duration of postoperative analgesia during retrobulbar block.Design
Prospective, randomized controlled trial.Setting
Operating room and Postanesthesia Care Unit of a university-affiliated hospital.Subjects
80 ASA physical status 1, 2, and 3 patients undergoing vitreoretinal surgery with or without scleral buckling.Interventions
Patients in the control group (n = 40) received a retrobulbar block with 4.5 mL of lidocaine-bupivacaine and 0.5 mL of saline. Clonidine group patients (n = 40) received 4.5 mL of lidocaine-bupivacaine and 0.5 μg/kg of clonidine in a 0.5 mL volume.Measurements
The time to first analgesic request, frequency of postoperative pain, and number of postoperative analgesic requests per patient were assessed.Main Results
37 patients in the control group (92.5%) versus 24 patients (60%) in the clonidine group reported pain postoperatively (P = 0.001), with a shorter time to first analgesic request noted in the control group (4.9 ± 3 vs 11.9 ± 5.3 hrs; P < 0.001). The median number of postoperative analgesic requests per patient during the first 24 hours was higher in the control group than the clonidine group [2 (0-3) vs. 1 (0-3); P < 0.001].Conclusions
The addition of clonidine 0.5 μg/kg to the local anesthetics of a retrobulbar block for vitreoretinal surgery decreases the frequency of postoperative pain and prolongs the time of analgesia. 相似文献19.
Purpose
Perinatal care of infants with congenital diaphragmatic hernia (CDH) is nonstandardized and costly. We examined a risk-adjusted cohort of patients with CDH and hypothesized that (1) among CDH survivors, the cost of the birth admission would be proportional to illness severity, and (2) this cost would be significantly higher compared with a matched non-CDH cohort.Methods
A retrospective review of costs and outcomes for all patients with CDH admitted to British Columbia Children's Hospital between 1999 and 2003 was performed. Risk grouping of patients with CDH using a validated admission severity score (Score for Neonatal Acute Physiology-version II [SNAP-II]) was conducted, enabling comparison among infants surviving to discharge. Hospital costs were also compared with a contemporaneous, non-CDH cohort matched for birth weight and SNAP-II.Results
Thirty-two infants with CDH were included, of who 5 required extracorporeal membrane oxygenation. Twenty-three (72%) infants survived to discharge, with an average length of stay of 46 days. Average cost per survivor to discharge was $54,102 (vs $13,722 for the non-CDH cohort; P < .05). After SNAP-II stratification of survivors into low-, moderate-, and high-risk groups, a significant cost difference was noted between the moderate- and low-risk and high- and low-risk groups, respectively.Conclusions
Infants born with CDH require costly care and can be expected to consume disproportionate resources. Admission SNAP-II score correlates with total cost to discharge. Risk stratification and cost comparison of larger CDH populations may allow identification of cost-efficient treatment strategies. 相似文献20.
