Clinical Trial
Neonates undergoing pyloric stenosis repair are at increased risk of difficult airway management: secondary analysis of the NEonate and Children audiT of Anaesthesia pRactice IN Europe.
BACKGROUND
Hypertrophic pyloric stenosis in otherwise healthy neonates frequently requires urgent surgical procedure but anaesthesia care may result in respiratory complications, such as hypoxaemia, pulmonary aspiration of gastric contents, and postoperative apnoea. The primary aim was to study whether or not the incidence of difficult airway management and of hypoxaemia in neonates undergoing pyloric stenosis repair was higher than that in neonates undergoing other surgeries.
METHODS
Data on neonates and infants undergoing anaesthesia and surgery for pyloric stenosis were extracted from the NEonate and Children audiT of Anesthesia pRactice In Europe (NECTARINE) database, for secondary analysis.
RESULTS
We identified 310 infants who had anaesthesia for surgery for pyloric stenosis. Difficult airway management (more than two attempts at laryngoscopy) was higher in children with pyloric stenosis when compared with the entire NECTARINE cohort (7.9% [95% confidence interval {CI}, 5.22-11.53] vs 4.4% [95% CI, 1.99-6.58]; relative risk [RR]=1.81 [95% CI, 1.21-2.69]; P=0.004), whereas transient hypoxaemia with oxygen saturation <90% was comparable between the two cohorts. Postoperative complications occurred in 16 children (5.6%) within the 30-day follow-up. No mortality was reported at 30 and 90 days.
CONCLUSIONS
Children undergoing surgery for pyloric stenosis had a higher incidence of difficult intubation compared with the entire NECTARINE cohort.

Meta-Analysis
INTRODUCTION
Infantile hypertrophic pyloric stenosis is treated by either open pyloromyotomy (OP) or laparoscopic pyloromyotomy (LP). The aim of this meta-analysis was to compare the open versus laparoscopic technique.
METHODS
A literature search was conducted from 1990 to February 2021 using the electronic databases MEDLINE, Embase, and Cochrane Central Register of Controlled Trials. Primary outcomes were mucosal perforation and incomplete pyloromyotomy. Secondary outcomes consisted of length of hospital stay, time to full feeds, operating time, postoperative wound infection/abscess, incisional hernia, hematoma/seroma formation, and death.
RESULTS
Seven randomized controlled trials including 720 patients (357 with OP and 363 with LP) were included. Mucosal perforation rate was not different between groups (relative risk [RR] LP versus OP 1.60 [0.49-5.26]). LP was associated with nonsignificant higher risk of incomplete pyloromyotomy (RR 7.37 [0.92-59.11]). There was no difference in neither postoperative wound infections after LP compared with OP (RR 0.59 [0.24-1.45]) nor in postoperative seroma/hematoma formation (RR 3.44 [0.39-30.43]) or occurrence of incisional hernias (RR 1.01 [0.11-9.53]). Length of hospital stay (-3.01 h for LP [-8.39 to 2.37 h]) and time to full feeds (-5.86 h for LP [-15.95 to 4.24 h]) were nonsignificantly shorter after LP. Operation time was almost identical between groups (+0.53 min for LP [-3.53 to 4.59 min]).
CONCLUSIONS
On a meta-level, there is no precise effect estimate indicating that LP carries a higher risk for mucosal perforation or incomplete pyloromyotomies compared with the open equivalent. Because of very low certainty of evidence, we do not know about the effect of the laparoscopic approach on postoperative wound infections, postoperative hematoma or seroma formation, incisional hernia occurrence, length of postoperative stay, time to full feeds, or operating time.

BACKGROUND AND OBJECTIVE
Use of oral erythromycin in infants is associated with infantile hypertrophic pyloric stenosis (IHPS). The risk with azithromycin remains unknown. We evaluated the association between exposure to oral azithromycin and erythromycin and subsequent development of IHPS.
METHODS
A retrospective cohort study of children born between 2001 and 2012 was performed utilizing the military health system database. Infants prescribed either oral erythromycin or azithromycin as outpatients in the first 90 days of life were evaluated for development of IHPS. Specific diagnostic and procedural codes were used to identify cases of IHPS.
RESULTS
A total of 2466 of 1 074 236 children in the study period developed IHPS. Azithromycin exposure in the first 14 days of life demonstrated an increased risk of IHPS (adjusted odds ratio [aOR], 8.26; 95% confidence interval [CI], 2.62-26.0); exposure between 15 and 42 days had an aOR of 2.98 (95% CI, 1.24-7.20). An association between erythromycin and IHPS was also confirmed. Exposure to erythromycin in the first 14 days of life had an aOR of 13.3 (95% CI, 6.80-25.9), and 15 to 42 days of life, aOR 4.10 (95% CI, 1.69-9.91). There was no association with either macrolide between 43 and 90 days of life.
CONCLUSIONS
Ingestion of oral azithromycin and erythromycin places young infants at increased risk of developing IHPS. This association is strongest if the exposure occurred in the first 2 weeks of life, but persists although to a lesser degree in children between 2 and 6 weeks of age.

BACKGROUND
Infantile hypertrophic pyloric stenosis (IHPS) is the most common condition requiring surgery in infancy, but the etiology of IHPS is still unclear. The study aimed to analyze the epidemiological and clinical features of the infants with IHPS in our setting and determine the yearly trends in IHPS incidence in the Sarajevo Canton between 2007 and 2016.
METHODS
We retrospectively analyzed epidemiologic, clinical, and operative data of all infants undergoing pyloromyotomy for IHPS over ten years in the largest tertiary care facility in Bosnia and Herzegovina.
RESULTS
Fifty-three IHPS patients were diagnosed, yielding an overall incidence of 1.17 per 1000 live births (1.25 and 1.09 cases in 2007-2011 and 2012-2016, respectively). IHPS was more prevalent among male infants (ratio 6.6:1, p < 0.001). The mean age at onset of symptoms was 39.6 days (range, 17-107 days). The estimated median time from symptoms onset to hospitalization was 11 days (range, 1-17 days). The mean age at diagnosis was significantly longer in premature infants compared with term infants (p = 0.003). Both first-born rank and bottle-feeding were significantly associated with IHPS (p = 0.001 and p = 0.04, respectively). No seasonal variation associated with IHPS was detected (p = 0.25). No evidence was found of differences in the incidence of IHPS related to maternal age (p = 0.24) and smoking (p = 0.59).
CONCLUSION
Our data indicate a declining trend and provide insights into the clinical characteristics of IHPS in Bosnia and Herzegovina. Most of the obtained results are in line with the published data and could improve the quality of local pediatric services.

BACKGROUND
Normalization of metabolic alkalosis is an important pillar in the treatment of infantile hypertrophic pyloric stenosis (IHPS) because uncorrected metabolic alkalosis may lead to perioperative respiratory events. However, the evidence on the incidence of respiratory events is limited. We aimed to study the incidence of peroperative hypoxemia and postoperative respiratory events in infants undergoing pyloromyotomy and the potential role of metabolic alkalosis.
MATERIALS AND METHODS
We retrospectively reviewed all patients undergoing pyloromyotomy between 2007 and 2017. All infants received intravenous fluids preoperatively to correct metabolic abnormalities close to normal. We assessed the incidence of perioperative hypoxemia (defined as oxygen saturation [SpO] < 90% for > 1min) and postoperative respiratory events. Additionally, the incidence of difficult intubations was evaluated. We performed a multivariate logistic regression analysis to evaluate the association between admission or preoperative serum pH values, bicarbonate or chloride, and peri- and postoperative hypoxemia or respiratory events.
RESULTS
Of 406 included infants, 208 (51%) developed 1 or more episodes of hypoxemia during the perioperative period, of whom 130 (32%) experienced it during induction, 43 (11%) intraoperatively, and 112 (28%) during emergence. About 7.5% of the infants had a difficult intubation and 17 required more than 3 attempts by a pediatric anesthesiologist. Three patients developed respiratory insufficiency and 95 postoperative respiratory events were noticed. We did not find a clinically meaningful association between laboratory values reflecting metabolic alkalosis and respiratory events.
CONCLUSIONS
IHPS frequently leads to peri- and postoperative hypoxemia or respiratory events and high incidence of difficult tracheal intubations. Preoperative pH, bicarbonate, and chloride were bad predictors of respiratory events.

Meta-Analysis Review
PURPOSE
Macrolide antibiotics, erythromycin, in particular, have been linked to the development of infantile hypertrophic pyloric stenosis (IHPS). Our aim was to conduct a systematic review of the evidence of whether post-natal erythromycin exposure is associated with subsequent development of IHPS.
METHODS
A systematic review of postnatal erythromycin administration and IHPS was performed. Papers were included if data were available on development (yes/no) of IHPS in infants exposed/unexposed to erythromycin. Data were meta-analysed using Review Manager 5.3. A random effects model was decided on a priori due to heterogeneity of study design; data are odds ratio (OR) with 95 % CI.
RESULTS
Nine papers reported data suitable for analysis; two randomised controlled trials and seven retrospective studies. Overall, erythromycin exposure was significantly associated with development of IHPS [OR 2.45 (1.12-5.35), p = 0.02]. However, significant heterogeneity existed between the studies (I = 84 %, p < 0.0001). Data on erythromycin exposure in the first 14 days of life was extracted from 4/9 studies and identified a strong association between erythromycin exposure and subsequent development IHPS [OR 12.89 (7.67-2167), p < 0.00001].
CONCLUSION
This study demonstrates a significant association between post-natal erythromycin exposure and development of IHPS, which seems stronger when exposure occurs in the first 2 weeks of life.

Meta-Analysis Review
BACKGROUND
There is an ongoing debate about whether laparoscopic pyloromyotomy (LP) or open pyloromyotomy (OP) is the best option for treating hypertrophic pyloric stenosis (HPS). The aim of this study was to compare the results of both surgical strategies by means of a systematic review and meta-analysis of the available literature.
METHODS
A systematic search for randomized clinical trials (RCTs) comparing OP and LP was conducted. Studies were reviewed independently for quality, inclusion and exclusion criteria, and outcomes. Primary outcome was major postoperative complications (i.e., incomplete pyloromyotomy, perforation, and need for reoperation). Secondary outcomes were time to full feed, postoperative hospital stay, and any other postoperative complications.
RESULTS
Four RCTs with a total of 502 patients (OP 255, LP 247) fulfilled the inclusion criteria and were analyzed in this review. These trials showed an absolute incidence of major postoperative complications of 4.9% in the LP group. Meta-analysis showed that LP did not lead to significantly more major postoperative complications (ARR 3%, 95% CI -3 to 8%) than OP. The mean difference in time to full feed was significant (2.27 h, 95% CI -4.26 to -0.29 h) and the mean difference in postoperative hospital stay tended to be shorter (2.41 h, 95% CI -6.10 to 1.28 h), both in favor of LP.
CONCLUSION
So far, the major postoperative complication rate after LP for HPS is not substantially higher than after OP. Because time to full feed and postoperative hospital stay are at best a few hours shorter after LP than after OP, the laparoscopic technique might be acknowledged as the standard of care if the major postoperative complication rate is low. Hence, this laparoscopic procedure should preferably be performed in centers with pediatric surgeons with expertise in this procedure.
