[Nissen fundoplication in children under 1 year of age: is age important?]

AIM

Nissen fundoplication (NF) is a procedure with technical difficulties and variable functional prognosis the lower the patient's age is. Our objective is to analyze the peculiarities of this procedure when performed in children under 1 year.

MATERIALS AND METHODS

Retrospective study of the NF in our center from 1999 to 2014. We review the differences between children under 1 year of age and the leftover of the series: history, indications, surgical approach and postoperative outcomes.

RESULTS

A total of 233 patients (57.1% male) were operated at a median age of 2.3years (1 month-17.31years), of which 82 (35.2%) were younger than 1 year. It Open surgery was performed in 118 patients (86.6% of children under 1 year and 31.1% over 1 year, p <0.05) and laparoscopic in 115. The median follow-up was 3.92 ± 3.24 years. Patients under 1 year had a higher number of comorbidities (91.5% vs 81.5%), respiratory symptoms (76.8% vs 49.7%) and postoperative complications (20.7% vs 9.9% OR = 2.4), with statistically significant differences (p <0.05). There were not differences in the Nissen's failure rate (15.9% vs 8.6%) or the need of reoperation (15.9% vs 7.9%).

CONCLUSIONS

Patients under 1 year operated by NF form a group with particular indications and comorbidities. Although the outcomes among these patients are favourable, surgical complications are more frequent than in older children.

[Noninvasive positive pressure ventilation in postoperative period of tracheal surgery]

OBJECTIVES

Reconstructive surgery of the airway often means prolonged periods of intubation during the post-operatory period, increasing the needs for drugs and favoring the appearance of infectious complications. We present an original system of ventilatory support with non-invasive positive pressure ventilation (NIPPV) using in patients subjected to reconstructive surgery of the airway.

PATIENTS AND METHODS

A retrospective study in patients undergoing reconstructive procedures of the airway in the year 2009 was carried out. We exclude those treated endoscopically and those who had vascular rings. The positive pressure mechanism used in the Surgery Critical Care Unit was a design made by the unit based on the circuit devised by Mapleson that provides optimum levels of ventilation without need for connection to a respiratory. We analyze the results, postoperatory intubation time, time dependent on NIPPV and medical treatment received.

RESULTS

A total of 7 patients (1 Female and 6 Males) with median age of 1.6 (0.1-7.5) years were included. The diagnoses were: 4 subglottic stenosis, 2 had tracheal stenosis and 1 subcarinal stenosis with involvement of both principal bronchioles. The techniques used were: laryngotracheoplasty with costal cartilage graft (4), tracheoplasty with costal cartilage (1) and sliding tracheoplasty (2) with bilateral bronchoplasty in one of them. The mean time of nasotracheal intubation was 3 days, and mean time of NIPPV was 2.3. No patient required reintubation and none had infectious complications.

CONCLUSIONS

Ventilatory support by VPPNI allows effective extubation in these patients, it being possible to maintain a safe airway. Infectious complications, frequent in prolonged intubations, were not observed in any of the cases.

[Traumatic diaphragmatic hernia: a vital need for an early diagnosis]

INTRODUCTION

Traumatic diaphragmatic hernia (HDT) is exceptional in children. Its diagnosis is usually delayed for appearing in the context of severe polytrauma. The aim is to analyze our series in relation to the severity scores.

PATIENTS AND METHODS

Five patients with HDT are presented. Age, biomechanics, clinical, ISS (injury severity score), ITP (pediatric trauma index), GCS (Glasgow coma scale), RTS (Revised Trauma Score) and treatment were studied. The probability of survival (Ps) was calculated with the TRISS method, Ps = 1/(1 + eb), b = b0 + bl (RTS) + b2 (ISS) + B3 (age).

RESULTS

There were two males and three females, mean age was six years old (range = 3-10). Traffic accident was the mechanism of the thoracoabdominal trauma in 80% and one was crushed by garage door. The affected side was right in two cases and left in three. Mean ISS was 41 (range = 32-57), ITP 6 (range = 2-9) and RTS 6.1 (range = 5.1 to 6.9). The main symptom was respiratory. Plain chest radiography was diagnostic in three patients, one by CT scann, and another was a finding at laparotomy. Two had liver herniation, one had tension gastrothorax and two had gastric perforations. All patients underwent surgery through the abdomen. Estimated survival by the TRISS method was respectively 86.6%, 78.2%, 57.2%, 84.7% and 57.1%, while the actual was 100%. One has a severe disability.

DISCUSSION

To study the biomechanics and semiology is essential in the early diagnosis of TDH in pediatric polytrauma and suspect it is mandatory prior to realize percutaneous chest procedures. The TRISS method has a great importance to assess the adult polytrauma, but specific scores are needed for children.

[The risk of necrotizing enterocolitis in newborns with congenital heart disease. a single institution-cohort study]

BACKGROUND/AIM

Necrotizing enterocolitis (NEC) is the most common gastrointestinal surgical disease among neonates. Congenital heart disease (CHD) is also a significant cause of infant morbidity and mortality and it is usually associated with prematurity, low birth weight, pulmonary and gastrointestinal disease, conditions that also account for the development of NEC. Our aim is to analyze the incidence and the risk factors for NEC in neonates with CDH admitted to the Neonatal Intensive Care Unit (NICU) in a 6 years period.

METHODS

All patients admitted in the NICU for any type of CDH from January 2003 to December 2008 comprised the cohort of this study. The primary outcome measure was the development of NEC in any stage. Sixteen independent variables were selected to include those factors previously correlated with NEC. Uni and multivariate statistical analysis were performed with SPSS 15.0 for Windows. Relative Risks (RR) are presented with 95% confidence intervals.

RESULTS

935 out of the 7803 neonates admitted during this period, 935 (11.9%) presented a CHD. Among them, 70 also had NEC (RR 8.4-17.8), 31 requiring surgical treatment (Bell stages III and IV). The risk for NEC was specially increased if CHD needed surgical correction (2.1-5.1) and among babies with very low birth weight (VLBW, <1,500 g) (2-4.8). After multivariate analysis the only independent variables associated with an increased risk of NEC were birth weight less than 1,500 g (2.2-7.4), the need of surgical correction of CHD (2.2-7.1) and a clinical picture of septicaemia (1.1-3.9).

CONCLUSIONS

The incidence of NEC is greater in neonates with CDH than in the normal newborn population. Early recognition of NEC should be warranted among CHD patients, specially in those with VLBW, surgical treatment of CHD and sepsis. In this sub-cohort of patients an increased risk of NEC should be suspected.
