The need for Paediatric Emergency Laparotomy Audit (PELA) in the UK

INTRODUCTION

The National Emergency Laparotomy Audit (NELA) has raised serious concerns about the processes of care and outcomes in adult emergency laparotomies in the UK. To date, no comparable data have been published for children. The aim of this study was to investigate the need for a similar audit in children.

METHODS

Data were collected retrospectively following NELA guidelines. Results were analysed using QuickCalcs (GraphPad Software, La Jolla, CA, US).

RESULTS

The study period spanned 7.5 years. A total of 161 patients were identified for inclusion in the audit. The median patient age was 2.8 years. Half (49%) of the cohort were deemed ASA (American Society of Anesthesiologists) grade ≥2. A history of previous abdominal surgery was noted in 37% of the patients. The median time from admission to operation was 15 hours. Over a third (39%) of the operations were performed out of hours. The most common indications for surgery comprised adhesive bowel obstruction (37%), intussusception (27%) and volvulus (9%).The median length of hospital stay was 8 days with the median postoperative stay being 6 days (NELA data 10.6 days). Half (51%) of the cases required intensive care following surgery. The 30-day mortality rate was 3.1%. The overall mortality rate was 4.3% (NELA data 16%). Patient care was led by a consultant surgeon in 100% of cases (NELA data 89%).

CONCLUSIONS

This is the first study in children that provides baseline data about the standards of care and outcomes from a single centre paediatric emergency laparotomy audit. A larger study using data from multiple centres would be of great benefit.

Thirty-days readmissions in pediatric surgery: The first U.K. experience

INTRODUCTION

The aim of this study was to investigate readmissions within 30days of operation (ReAd) in the setting of a tertiary pediatric surgical practice in the UK.

METHODS

Using Hospital Episode Statistics, cases that were readmitted within 30days of primary operation were identified retrospectively. Demographics including age, gender, preexisting comorbidities, diagnosis on primary admission and the treatment, length of stay, and diagnosis on readmission with treatment, including further surgical intervention, were collected from discharge summaries and hospital notes. Neonates were excluded from this study. Comorbidities, involving one or more systems, were also identified for each case of readmission. ReAds were classified into emergency and elective cohort depending on the nature of the primary operation. Outcomes were compared between these two groups. Data were quoted as median (range) unless indicated otherwise. Data were analyzed using SPSS software Desktop 22.0, using Mann-Whitney U and Chi-Squared tests, with a consideration that a P≤0.05 was significant.

RESULTS

A total of 2378 procedures were performed during the study period. Elective cases, including day cases, accounted for 77% (n=1837) of all cases. The remaining 23% (n=541) were emergency cases. Total unplanned readmission rate within 30days (ReAd) was 2%. Further surgical procedures were required in 38%. Having excluded neonates, the most common primary procedure leading to readmission within 30days was appendicectomy (26%). Overall, the most common cause for readmission within 30days was postoperative infection (30%). The ReAd in emergency cohort was 3.5% in comparison to 1.5% in elective, which was significantly different (P value=0.007).

CONCLUSION

Readmission within thirty days of primary procedure in pediatric surgery has little published data. An efficient discharge planning may play a vital role in preventing unwanted readmission. Elective operations had a significantly lower readmission rate than emergency operations. Having excluded neonates, appendicectomy was found to be the most common operation associated with readmission in the pediatric surgical practice. Although widely used as quality care indicator in adults, more studies are required to validate readmission rate as a quality of care indicator in pediatric surgery practice.

Prenatal ultrasound in the prediction of bowel obstruction in infants with gastroschisis

OBJECTIVE

To assess the value of prenatal ultrasound in predicting bowel obstruction requiring surgery in fetuses with prenatal diagnosis of gastroschisis.

METHODS

The database of our center was searched for cases with an antenatal diagnosis of gastroschisis. The ultrasound images were reviewed blindly to assess the presence of intra- or extra-abdominal bowel dilatation. Details of surgical procedures were noted and the discharge letters were obtained. Pediatric follow-up was also obtained from pediatric surgeons, general practitioners or parents.

RESULTS

In the 10-year period between November 1998 and September 2008 there were 62 cases with a prenatal diagnosis of gastroschisis. Postnatal outcome was not available for five cases, four pregnancies underwent termination and intrauterine fetal demise occurred in five cases. A final population of 48 liveborn infants was available for analysis. Intra-abdominal bowel dilatation was identified in 14 of these 48 fetuses (29.2%) and extra-abdominal bowel dilatation in 30 (62.5%) fetuses on prenatal ultrasound images. Eight fetuses (16.7%) had bowel obstruction. The relative risk of bowel obstruction with intra-abdominal bowel dilatation was 4.05 (95% CI, 1.12-14.70). On the other hand, the relative risk of bowel obstruction with extra-abdominal bowel dilatation was 1.0 (95% CI, 0.37-3.70). Four babies died, two of whom had intra- and one had extra-abdominal bowel dilatation.

CONCLUSIONS

Intra-abdominal dilatation of the bowel on prenatal ultrasound examination appears to predict postnatal bowel obstruction and the need for surgical resection. Extra-abdominal bowel dilatation is observed frequently on prenatal ultrasound scans, but is not predictive of bowel obstruction.

Early high C-reactive protein in infants with open abdominal wall defects does not predict sepsis or adverse outcome

AIM

To study CRP values and relate it to outcome in infants with antenatal diagnosis of gastroschisis, exomphalos and other surgical conditions.

METHODS

Over five years, infants admitted to our neonatal unit with gastroschisis, exomphalos and other surgical diagnoses were identified. Serum CRP measurements in first 5 days were studied. Group one included 33 gastroschisis patients, group two, 18 exomphalos patients, and group three, 38 patients with other surgical diagnoses. Outcome measures included TPN days, time to full feeds and duration of hospitalization.

RESULTS

Infants with gastroschisis were more premature (36.9 vs 38.1 weeks) with lower birth weights (2515 vs 3078 g), than infants with exomphalos. CRP values on admission in gastroschisis group were significantly higher than exomphalos and other diagnoses groups (33.7 +/- 6.4 vs 8.8 +/- 6.0 vs 5.7 +/- 2.0, respectively, p < 0.05). All blood cultures were sterile. There was no relationship between high CRP and death or adverse outcome (TPN days, time to full feeds or duration of hospitalization) in the gastroschisis group.

CONCLUSION

Infants with gastroschisis exhibit high early CRP, which may not indicate sepsis or adverse outcome. This increase can complicate the assessment of these infants. Clinicians should be aware of this finding as it could inform management decisions in this group.

Outcome of antenatally diagnosed abdominal wall defects

OBJECTIVE

To examine the natural history and detailed outcome of antenatally diagnosed abdominal wall defects.

METHODS

This was a retrospective review of the antenatal reports, pediatric surgery records and subsequent follow-up information of all cases of omphalocele and gastroschisis diagnosed in a 10-year period in our tertiary referral center.

RESULTS

There were 109 cases of abdominal wall defects, including omphalocele in 67 cases and gastroschisis in 42 cases. Of the 67 cases of omphalocele there were 26 (39%) with chromosomal abnormalities and 22 (33%) underwent termination of pregnancy, mainly for associated structural abnormalities. Of the ongoing 19 cases there were five (26%) in-utero deaths, 12 (63%) survivors and two (11%) neonatal deaths, both associated with prematurity. Excluding chromosomal abnormalities, the survival rate in isolated omphalocele was 7/16 (44%) whilst it was 5/25 (20%) in those with associated abnormalities. Gastroschisis was isolated in 40 (95%) cases. Among these 40 isolated cases there were two (5%) terminations. Of the 38 ongoing cases, there were two (5%) in-utero deaths, and 36 (95%) live births. Four of the 36 liveborn infants (11%) died in the postoperative period owing to complications of small bowel atresia.

CONCLUSIONS

Although only 18% of infants with antenatally diagnosed omphalocele were alive in the neonatal period, postoperative morbidity was low. The majority (90%) of fetuses with antenatally diagnosed gastroschisis survived to delivery, but the mortality in affected newborns was 11%.
