Ward reduction of gastroschisis: risk stratification helps optimise the outcome

European reference network for rare inherited congenital anomalies (ERNICA) evidence based guideline on the management of gastroschisis

BACKGROUND

The European Reference Network for rare Inherited Congenital Anomalies, ERNICA, guidelines for gastroschisis cover perinatal period to help teams to improve care.

METHOD

A systematic literature search including 136 publications was conducted. Research findings were assessed following the GRADE methodology. The evidence to decision framework was used to determine the strength and direction of recommendations.

RESULTS

The mode or timing of delivery do not impact neonatal mortality, risk of NEC or time on parenteral nutrition (PN). Intra or extra abdominal bowel dilatation predict complex gastroschisis and longer length of hospital stay but not increased perinatal mortality. Outcomes after Bianchi procedure and primary fascia closure under anesthesia are similar. Sutureless closure decreases the rate of surgical site infections and duration of ventilation compared to surgical closure. Silo-staged closure with or without intubation results in similar outcomes. Outcomes of complex gastroschisis (CG) undergoing early or delayed surgical repair are similar. Early enteral feeds starting within 14 days is associated with lower risk of surgical site infection.

RECOMMENDATIONS

The panel suggests vaginal birth between 37 and 39 w in cases of uncomplicated gastroschisis. Bianchi's approach is an option in simple gastroschisis. Sutureless closure is suggested when general anesthesia can be avoided, sutured closure. If anesthesia is required. Silo treatment without ventilation and general anesthesia can be considered. In CG with atresia primary intestinal repair can be attempted if the condition of patient and intestine allows. Enteral feeds for simple gastroschisis should start within 14 days.

Infectious outcomes of gastroschisis patients with intraoperative hypothermia

BACKGROUND

Perioperative hypothermia decreases nutrient and oxygen delivery to tissues and, in adult studies, increases the risk of infectious complications (ICs). Gastroschisis (GS) places newborns at risk for hypothermia by nature of exposed viscera and excessive heat loss. Although hypothermia is a known cause of mortality in GS, the rate of ICs in this at-risk cohort has not yet been delineated.

MATERIALS AND METHODS

A retrospective cohort study was performed at our single tertiary-referral hospital, evaluating patient and operative characteristics of all GS infants who underwent operative closure. Intraoperative temperatures were recorded, defining hypothermia as mild (35.5°C-35.9°C), moderate (35.0°C-35.4°C), or severe (<35°C). Temperature nadirs, procedural and anesthesia duration were observed. The primary outcome was 30-d surgical site infections. Secondary measures included other ICs.

RESULTS

Among 43 GS neonates, 21 (48.8%) had intraoperative hypothermia, classified as mild in 2 (4.7%), moderate in 8 (18.6%), and severe in 11 (25.6%). Nineteen ICs occurred in 35.9% of patients, including 10 (23.3%) surgical site infections. There was no association between hypothermia and ICs. Patient and operative characteristics were similar between normothermic and hypothermic groups, except that normothermic infants were more likely to have silos placed with delayed closure than hypothermic patients (63.6% versus 23.8%, P = 0.01).

CONCLUSIONS

Infants with GS are at high risk for hypothermia and ICs, though newborns with silos were less subject to temperature lability. A multiinstitutional study with greater power is needed to further investigate the relationship between perioperative hypothermia and surgical ICs.

Outcomes of infants with abdominal wall defects over 18years

BACKGROUND/PURPOSE

Infants with abdominal wall defects (AWD) are at risk of poor outcomes including prolonged hospitalization, infections and mortality. Our objective was to describe and compare the outcomes of infants admitted with gastroschisis and omphalocele over 18years.

METHODS

Population-based study of clinical data and outcomes of live-born infants with AWD admitted to all tertiary-level neonatal intensive care units in New South Wales and Australian Capital Territory from 1992 to 2009.

RESULT

There were 502 infants with AWD - 336 gastroschisis, 166 omphalocele. Infants with gastroschisis required a longer duration of total parenteral nutrition (19 vs 4days, p<0.05), longer hospitalization (28 vs 15days, p<0.05) and had a higher rate of systemic infection [23.5% vs 13.3%, OR 1.77 (1.15-2.74), p<0.05] compared to infants with omphalocele. Overall, omphalocele infants had higher mortality rate compared to gastroschisis infants [OR 2.77 (1.53, 5.04), p<0.05]. Gastroschisis mortality rates increased from epoch 1 to epoch 3 (4.2% to 8.8%).

CONCLUSION

Compared to infants with omphalocele, infants with gastroschisis required significantly longer hospitalization and parenteral nutrition with higher rates of infection. Infants with omphalocele had higher overall mortality rates. However, there has been an increase in the gastroschisis mortality rates but the cause for this is unclear.

Complex gastroschisis is a different entity to simple gastroschisis affecting morbidity and mortality-a systematic review and meta-analysis

BACKGROUND

Comparison of the outcome of newborns with simple (sGS) and complex gastroschisis (cGS: gastroschisis with atresia, necrosis, perforation or volvulus).

MATERIALS AND METHODS

We conducted a systematic database search, quality assessment and meta-analyzed relevant articles which evaluated the mortality and morbidity of newborns with cGS versus sGS. Risk ratios (RR) with 95% confidence interval (CI) were reported for categorical data, and the mean difference (MD) was calculated for continuous data. Pooled estimates of RR and MD were computed using generic inverse variance and a random-effects model.

RESULTS

Of 19 identified reports, 13 eligible studies were included. The mortality of infants with cGS (16.67%) was significantly higher than sGS (2.18%, RR: 5.39 [2.42, 12.01], p<0.0001). Significantly different outcome was found for the following parameters: Infants with cGS are started on enteral feedings later and they take longer to full enteral feedings with a subsequent longer duration of parenteral nutrition. Their risk of sepsis, short bowel syndrome and necrotizing enterocolitis is higher. They stay longer in hospital and are more likely to be sent home with enteral tube feedings and parenteral nutrition.

DISCUSSION

Occurring in 17% of infants born with gastroschisis, complex gastroschisis is associated with a significantly increased morbidity and mortality. More research should be focused on this special subgroup of patients, not only on postnatal management, but additionally directing efforts to improve diagnosing and predicting complex gastroschisis prenatally as well as implement any probable fetal intervention to alleviate its disastrous outcome.

Long-term review of sutureless ward reduction in neonates with gastroschisis in the neonatal unit

BACKGROUND

A sutureless ward reduction (SWR) protocol was implemented in the neonatal intensive care unit of a tertiary level hospital in 1999. Although the short-term outcomes associated with SWR have been documented, the long-term outcomes are unknown.

METHODS

Retrospective data were collected from the medical records of all neonates with gastroschisis from September 1999 to December 2010. Data on their growth and development and the prevalence of any health problems were collected.

RESULTS

Eighty-eight patients with gastroschisis were managed over an 11 year period. Forty-four of these patients received SWR, with 2 deaths in the neonatal period. In the 42 survivors, 35 patients were reviewed at a median age of 7 years and 10 months (range, 6-134 months; interquartile range, 37-124 months). One patient experienced failure to thrive and developmental delay, and later died of a medical complication. Thirty-two patients (91.4%) developed an umbilical hernia, only 2 of whom required umbilical herniotomy. Four patients (11.4%) developed small bowel obstruction, all within the first year.

CONCLUSION

Most patients with SWR exhibited normal growth with minimal bowel complications. Despite the high incidence of umbilical hernia, the majority resolved spontaneously and did not require subsequent herniotomy.
