Obstruction In Infants Research Articles

Nonsurgical improvement of severe upper airway obstruction in infants with Robin sequence and cleft palate using Stanford orthodontic airway plate treatment.

Severe respiratory distress of neonates with Robin sequence is traditionally managed by surgery. Stanford orthodontic airway plate treatment (SOAP) is a nonsurgical option. The study aimed to determine whether SOAP can improve polysomnography parameters of neonates with Robin sequence. Polysomnography of neonates with Robin sequence treated with SOAP at a single hospital were retrospectively analyzed. Patients without polysomnography at all 4 time points (pre, start of, mid, and posttreatment) were excluded. Data were analyzed using a linear mixed effects model. Sixteen patients were included. All patients had cleft palate. The median age (minimum, maximum) at the start of treatment was 1.1 months (0.3, 5.1) with the treatment duration of 4.5 months (3.5, 6.0). The mean obstructive apnea-hypopnea index (95% confidence interval) decreased from 39.3 events/h (32.9, 45.7) to 12.2 events/h (6.7, 17.7) (P < .001), obstructive apnea index decreased from 14.1 (11.2, 17.0) events/h to 1.0 (-1.5, 3.5) events/h (P < .001), and oxygen nadir increased from 79.9% (77.4, 82.5) to 88.2% (85.5, 90.8) (P < .001) between pre and start of treatment. Respiratory improvements were sustained during and after the treatment. All patients avoided mandibular distraction osteogenesis or tracheostomy following SOAP. As being a rare diagnosis, the number of participants was, as expected, low. However, the current study shows that SOAP can improve polysomnography parameters, demonstrating its potential utility before surgical interventions for neonates with Robin sequence and cleft palate experiencing severe respiratory distress.

Predictive Factors for Bowel Resection in Childhood Intussusception.

Intestinal intussusception is the most common cause of intestinal obstruction in infants and children under 3 years of age. Any delay in diagnosis or management can lead to intestinal ischaemia and perforation. The aim of this study is to determine the sociodemographic and clinical risk factors associated with bowel resection in infants and children with intussusception. This is a retrospective analytical study of 118 patients operated at the Hassan II Hospital and University of Fez between 1 January 2008 and 1 January 2018. A comparison of risk factors between patients with and without bowel resection was performed using multivariate logistic regression. One hundred and eighteen patients met the inclusion criteria. Of these, 44% had undergone bowel resection. Age >2 years (P = 0.006), duration of symptoms progression of more than 2 days (P = 0.002), bilious vomiting (P = 0.04) and palpation of an abdominal mass (P = 0.01) were significantly associated with bowel resection. Multivariate logistic regression showed that age <2 years (odds ratio [OR] =4.47 95% confidence interval [CI]: 1.12-17.78) and duration of symptom progression of more than 2 days (OR = 2.62 95% CI: 1.12-6.11) were independent risk factors for bowel resection. Intussusception that occurs in child old than 2 years of age, or which has progressed for more than 2 days, is associated with an increased risk of intestinal resection.

Ultrasound imaging of bowel obstruction in infants and children.

We review the etiologies of bowel obstruction in infants and children that can be identified on ultrasound (US) including perforated appendicitis, intussusception, foreign body ingestion, colonic volvulus, intra-abdominal mass lesions, internal hernia, and stricturing inflammatory bowel disease. US can potentially identify the cause of bowel obstruction in these age groups, without the need for additional cross-sectional imaging, and can aid in patient management including interventional and surgical planning. Hence, it is important to be familiar with the sonographic imaging findings of bowel obstruction in infants and children.

A Comparison of Drug-Induced Sleep Endoscopy Findings in Infants and Toddlers.

To compare patterns of obstruction in infants and toddlers with obstructive sleep apnea (OSA) by analyzing drug-induced sleep endoscopy (DISE) examinations. Retrospective chart review. An academic tertiary care pediatric hospital at a single institution. Children aged ≤3 years who underwent DISE with propofol titration from 2020 to 2022 were included in the study. Data extracted included age, body mass index, comorbidities, and polysomnography parameters. The sites of anatomic obstruction during DISE were recorded using a validated 10-site scoring system. A total of 86 children underwent DISE, including 15 infants (<1year) and 71 toddlers (>1≤3years). Sixty-two percent were male and 37% were female. The mean age of the infant group was 9.6 months (95% confidence interval[CI]: 7.92, 11.28 months), and the mean age of the toddler group was 2.3years (95% CI: 2.06, 2.50years). The mean total number of sites of obstruction was not significantly different between infants (N = 2.5) and toddlers (N = 3.2, P = .086). The most common subsite of significant obstruction in both infants and toddlers was the aryepiglottic folds (46.7% and 36.8%, respectively; P = .578). The sites of obstruction and frequency of their occurrence were not significantly different between the 2groups. Multisite airway obstruction is common among children with OSA, especially at the epiglottis, aryepiglottic folds, and tongue base. There is no difference in sites of obstruction and their frequency between toddlers and infants.

Acute Intestinal Intussusception in Children at Somine Dolo Hospital in Mopti

Introduction: It is defined as the penetration of an intestinal segment and its meso into the lumen of the distal segment by a glove-like turning mechanism (invagination sausage) whose perpetuation results in obstruction of the intestinal lumen and the intestinal necrosis. Acute intestinal intussusception (IIA) or intussusception is the most common cause of intestinal obstruction in infants. IIA is primary or idiopathic in 90% and mainly affects infants between 2 months and 2 years with a peak frequency between 6 and 9 months. Objectives: To study acute intestinal intussusception in children aged 0 to 15 years in the general surgery department of the “SOMINE DOLO” hospital in Mopti. Method: This was a retrospective, descriptive study which took place from January 2017 to September 2020 in the general surgery department of the Sominé Dolo Hospital in Mopti. Result: During the study period, 1244 children were operated on including 32 cases of IIA, representing a frequency of 2.57% of surgical interventions. The male gender was in the majority (62.5%) with a sex ratio of 1.7. The average consultation time was 6.2 ± 4.3 days. Infants were the majority in 68.8% of cases and the main reason for consultation was abdominal pain (78.1%). The average treatment time was 2.9 hours. The ileocecocolic form was more frequent in 50% cases. Manual disinvagination was most often performed in 75% and the postoperative course was simple in 56.3%. Conclusion: AII is a common condition in our structure. It mainly affects infants and boys. Patients consult late but early treatment reduces mortality.

Correlation between Doppler sonography and diuretic renogram in the diagnosis and follow-up of infants with unilateral pelvi-ureteric junction obstruction

BackgroundConventionally, diuretic isotope renogram is used to establish and quantify severity of the obstruction in pelvi-ureteric junction obstruction. Doppler ultrasonography too assesses obstruction by evaluating the resistive index (RI) and resistive index ratio (RIR) in the intrarenal vasculature of the kidneys. This study aimed to note correlation between RI, RIR on Doppler ultrasonography and perfusion index (PI) on diuretic isotope renogram in suspect unilateral pelvi-ureteric junction obstruction in infants. A prospective study (2016–2019) in infants with suspect unilateral hydronephrosis, i.e. anteroposterior pelvic diameter (APPD) > 15 mm, divided into Group A (0–6 months) and Group B (6–12 months) based on the age at diagnosis. The RI, RIR and PI were noted at diagnosis, at 3 and 6 months, post-interventions and the correlation assessed.Results37/94 with hydronephrosis were included in the study. 30 among these underwent surgical intervention. A decrease in RI and RIR and increase in PI following surgery were documented at follow-up. Also, the improvement was statistically more significant in the first 3 months following intervention.ConclusionsAn increased RI and RIR and a decreased PI are good indicators of obstruction in unilateral hydronephrosis in infants. The decline in RI with increase in PI following relief of obstruction shows a positive correlation between the two. Doppler sonography may be effective in monitoring unilateral hydronephrosis with unobstructed or equivocal renogram curves and consequently negate the need for repeated nuclear scans.

Clinical application of endoscopic diaphragmotomy and dilation in a congenital duodenal diaphragm.

A congenital duodenal diaphragm (CDD) is a rare cause of duodenal obstruction in infants and children. The traditional approach to treatment has been surgical intervention either with excision and duodenoplasty or with bypass through a duodenoduodenostomy, which is invasive and carries the risk of anastomotic leakage. To summarize the key points of differential diagnosis and treatment of a CDD under gastroscopy and to evaluate its efficacy and safety. The clinical data of patients with a duodenal obstruction diagnosed and treated by gastroscopy in our hospital between January 2019 and December 2022 were retrospectively analyzed. The gastroscopic features of the CDD were summarized. The clinical outcomes of patients with CDD treated by gastroscopy were collected and investigated. A total of 13 children with a duodenal obstruction underwent a gastroscopic examination and/or treatment, and of these, 10 were diagnosed as having a CDD and 3 were finally diagnosed as having an annular pancreas. A dome-shaped structure during inspiration (9/10) and a guidewire that could be inserted through the opening into the distal lumen (6/10) were the gastroscopic features of the CDD, while the annular pancreas had none of these features. The 10 patients, 4 men and 6 women with the CDD, were treated through endoscopic diaphragmotomy and dilation. The age and weight at operation was 15 days to 7 years (M: 2.25 years) and 2.85-22 kg (M: 13.6 kg), respectively. A total of 11 endoscopic operations were performed in the 10 patients. The time of single operation was 15-55 min (M: 38 min). The patients did not experience complications such as bleeding, pneumoperitoneum, and duodenal papilla injury during the operation. Feeding was started 12-24 h after surgery, and the patients were discharged 2-10 days (M: 7 days) postoperatively. The patients were followed up for 3-36 months (M: 17 months), and none of them had a recurrence of vomiting. However, three showed a recurrence of stenosis in upper gastrointestinal imaging, one of whom underwent a partial diaphragm resection again 2 months after the primary treatment. A CDD can be confirmed by endoscopy based on its characteristic features. Endoscopic diaphragmotomy and balloon dilation are safe and effective, which can be a new option for minimally invasive treatment of a CDD.

Exploring the Infectious Contribution to Intussusception Causality Using the Effects of COVID-19 Lockdowns in Australia: An Ecological Study.

Intussusception is the primary cause of acute bowel obstruction in infants. The majority of cases <2 years of age are classed as idiopathic, with viral infection implicated as one of the causes. Coronavirus disease 2019 (COVID-19) public health measures led to significant decreases in communicable disease prevalence. During these times, reductions in intussusception frequency were greater than would be expected with our previous understanding of its infectious etiology. We conducted a retrospective, multistate, ecological study over a 12-year period. Monthly case numbers of "intussusception"-coded admissions (code K56.1; International Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification) were acquired from state-wide admissions data sets from New South Wales, Victoria, and Queensland, representing 77.62% of the eligible Australian population. These counts within differing jurisdictional lockdowns were compared with non-lockdown periods in order to investigate a correlation between intussusception frequency and lockdown periods. We found a negative association between intussusception frequency and lockdown periods in both eligible states. The largest reductions were seen in the <2-year age groups, with Victoria experiencing a 62.7% reduction (rate ratio, 0.37; P < .001) and New South Wales a 40.1% reduction (0.599; P = .006) during lockdown times. Controls for variations in lockdown restrictions between both regional and metropolitan areas also showed expected decreases. Our ecological study demonstrates significant decreases in the frequency of pediatric intussusception admissions during the COVID-19 lockdown periods. The unexpected magnitude of the reductions suggests that the true proportion of infectious disease-caused idiopathic intussusception is greatly underestimated.

Pyeloplasty may reverse the effect of growth delay from ureteropelvic junction obstruction in infants.

To determine if children with UPJO demonstrate a clinically significant change in somatic growth following pyeloplasty. We retrospectively evaluated the growth chart data of infants with SFU grade 3 or 4 congenital hydronephrosis at our institution from 2015 to 2022. Of those, 35 patients underwent pyeloplasty and 66 had no surgical intervention. Patients met criteria if they had SFU 3 or 4 hydronephrosis and MAG3 renal scan. If patients underwent surgery, height and weight percentiles were recorded from the pre-op and 6-16-month follow-up visits. In non-surgery patients, measurements were taken near the median age of surgery in the intervention group and 6-16months later. Interval changes in group height and weight percentiles are compared for significant changes. The surgery and non-surgery groups did not differ in terms of gender (71% vs 74% Male), starting age (296 vs 244days), starting weight (58th vs 52nd percentile), or time between measurements (255 vs 260days), though the surgery group had significantly less height in the pre-operative period (43rd vs 55th percentile, p = 0.050) and were more likely to have delayed drainage on renal scan (83% w/delay vs 35%). The surgery group showed a significant increase in height (18.9 percentiles; 95% CI 11-27) and weight (6.0 percentiles; 95% CI 0.50-12) after intervention. Patients with congenital hydronephrosis due to UPJO that underwent pyeloplasty showed a significant increase in weight and height at 6-16months postoperatively compared to those that were managed with close observation. This suggests UPJO might lead to growth delay in infants.

Minimally invasive pyeloplasty versus open pyeloplasty for ureteropelvic junction obstruction in infants: a systematic review and meta-analysis.

To compare the perioperative outcomes and success rates of minimally invasive pyeloplasty (MIP), including laparoscopic and robotic-assisted laparoscopic pyeloplasty, with open pyeloplasty (OP) in infants. In September 2022, a systematic search of PubMed, EMBASE, and the Cochrane Library databases was undertaken. The systematic review and meta-analysis were conducted in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, with the study registered prospectively in the PROSPERO database (CRD42022359475). Eleven studies were included. Dichotomous and continuous variables were presented as odds ratios (OR) and standard mean differences (SMD), respectively, with their 95% confidence intervals (CI). Compared to OP, a longer operation time and shorter length of stay were associated with MIP (SMD: 0.96,95% CI: 0.30 to 1.62, p=0.004, and SMD: -1.12, 95% CI: -1.82 to -0.43, p=0.002, respectively). No significant differences were found between the MIP and OP in terms of overall postoperative complications (OR:0.84, 95% CI: 0.52 to 1.35, p=0.47), minor complications (OR: 0.76, 95% CI: 0.40 to 1.42, p=0.39), or major complications (OR: 1.10, 95% CI: 0.49 to 2.50, p=0.81). In addition, a lower stent placement rate was related to MIP (OR: 0.09, 95% CI: 0.02 to 0.47, p=0.004). There was no statistical difference for success rate between the MIP and OP (OR: 1.35, 95% CI: 0.59 to 3.07, p=0.47). Finally, the results of subgroup analysis were consistent with the above. Our meta-analysis demonstrates that MIP is a feasible and safe alternative to OP for infants, presenting comparable perioperative outcomes and similar success rates, albeit requiring longer operation times. However, it is essential to consider the limitations of our study, including the inclusion of studies with small sample sizes and the combination of both prospective and retrospective research designs.

Chylolymphatic cyst as a rare cause of acute intestinal obstruction in infants

BackgroundChylolymphatic cysts are benign pathology in lymphatic vessels due to obstruction in the lymphatic system. Their incidence is still unknown. However, they account for approximately 3 to 9% of all pediatric lymphangiomas. Most of these lesions are asymptomatic and are discovered accidentally. They can be presented with nonspecific abdominal pain, vomiting, and changes in bowel habits. Rarely, chylolymphatic cysts can as intestinal obstruction, volvulus or even torsion.Case presentationA 3-month-old male presented to our unit with manifestations of acute intestinal obstruction. Abdominal examination revealed signs of generalized peritonitis and intestinal obstruction. Abdominal ultrasound revealed minimal turbid intraperitoneal collections and no motility of bowel loops. Plain erect abdominal radiograph revealed multiple small bowel air fluid levels. Abdominal exploration revealed a large chylolymphatic cyst causing acute intestinal obstruction. Excision of the cysts was done with preservation of adjacent bowel loop. The patient was discharged in good health on the 6th day postoperative. A chylolymphatic cyst with a diameter of 5 cm was identified by histological investigation.ConclusionsMost chylolymphatic cysts in infants are asymptomatic, but they can cause fatal complications such as intestinal obstruction, volvulus, or even torsion.

Small bowel obstruction in infants due to complicated Meckel’s diverticulum: A case series

Objectives: Our purpose is to illustrate the radiological aspects of Meckel’s diverticulum as an etiology of small bowel obstruction in infants. Material: We report a group of 4 patients with Meckel’s diverticulum complicated with small bowel obstruction that underwent surgery. We reviewed patient records, clinical presentation, ultrasound and CT imaging and intraoperative findings. Results: All included patients presented symptoms of bowel obstruction, one patient presented acute abdomen symptoms. The median age of our group was 5 years, all patients were males. All patients underwent radiological explorations. Ultrasound showed small bowel dilatation in all cases, and CT scan confirmed small bowel obstruction with ischemic complications in one patient. All of the 4 patients had laparotomy with the finding of MD responsible of small bowel obstruction in all cases, with on case of perforated loop and latero-caecal abscess. The obstruction was secondary to fibrous adhesions in three cases and the omphalomesenteric duct in one cases. All the patients had normal evolution with no post-operative complications. Conclusion: Meckel’s diverticulum represents a rare embryological remnant. It is a differential diagnosis in pediatric bowel obstruction and remains an intraoperative surprise despite the very abvanced imaging studies.

Caring for Infants with Robin Sequence Treated with the Tübingen Palatal Plate: A Review of Personal Practice.

The Tübingen Palatal Plate (TPP) is a minimally invasive yet highly effective functional orthodontic treatment for upper airway obstruction in infants with Robin Sequence (RS). It consists of a palatal plate to cover the cleft and a velar extension that shifts the root of the tongue forward. We review our practical experience with this approach. First, upon admission, our local orthodontists perform an (3-D) intraoral scan of the maxilla. Based on the scan data, the TPP is manufactured in a semi-digital workflow. The length and angulation of its extension is checked via awake laryngoscopy and the effectiveness confirmed by a sleep study. Plates are kept in place by adhesive cream. When inserting the TPP, the tip of the tongue must be visible. Next, metal fixation bows should be secured to the forehead using tape and elastic bands. Plates are removed daily for cleaning, and the oral mucosa is then checked for pressure marks. Feeding training (initially only via finger feeding) may even start before plate insertion. Breathing often normalizes immediately once the plate is inserted. For isolated RS, we have never had to perform a tracheostomy. This has largely been possible through our highly dedicated and competent team, particularly the nursing staff, and the early involvement of parents.

Complications of Mandibular Distraction Osteogenesis in Infants with Isolated Robin Sequence.

Mandibular Distraction Osteogenesis (MDO) is now the preferred procedure to alleviate airway obstruction in infants with severe Robin Sequence (RS). However, there have been very few studies investigating complications related to MDO surgery performed on patients affected by isolated RS. In this study, age at distraction, weight at distraction, preoperative intubation, repeat MDO and complications associated with MDO were included as variables. Minor, moderate and major problems were evaluated and recorded as surgical site infections (SSI), injuries to the facial nerve, self-extinction hypertrophic scars, temporomandibular joint ankylosis, device failures, early ossification and fibrous non-union. One hundred and fifty one patients with isolated RS were included. At distraction, the mean age was 72 days (12-540 days) and the mean weight was 4.05 kg (2.4-12.2 kg). Only one patient needed tracheostomy after MDO, and none required further distraction. Ultimately, the complication rate was 15.23%, and there was a total of 7.95% minor, 9.27% moderate and 0% major complications. Minor incidents included surgical site infection (SSI) managed with antibiotics taken orally (n = 8), neuropraxia in the VII cranial nerve (CN) (n = 1), and hypertrophic scarring (n = 3). Incidents reported as moderate were SSIs managed with intravenous antibiotics (n = 9), incision and drainage (n = 3) and self-extubation (n = 2). There was no case of TMJ ankylosis. There were no cases of early or premature ossification, fibrous non-union and device fracture. In conclusion, MDO is an effective and appropriate management technique for infants with isolated RS and severe airway obstruction. Infections at the surgery site accounted for the vast majority of the complications. Further investigations may be needed to determine the long-term consequences of MDO.

Determination of tissue tracer transit of Technetium-99m-mercaptoacetyltriglycine diuretic renography in infants with suspected ureteropelvic junction obstruction - A multicenter prospective observational study

There is an ongoing controversy regarding management of ureteropelvic junction obstruction in infants, with a shift towards a non-operative approach. However, precise predictors of outcome are lacking. Recent studies postulated a high prognostic value of Technetium-99m-mercaptoacetyltriglycine tissue tracer transit with regard to the development of an impaired differential renal function and its potential improvement following pyeloplasty. To evaluate the prognostic value of Technetium-99m-mercaptoacetyltriglycine tissue tracer transit for the occurrence of changes in differential renal function in infants with suspected unilateral ureteropelvic junction obstruction in a prospective observational multicenter study. Infants below 3 months of age with a unilateral isolated hydronephrosis≥grade 3 received ultrasound and Technetium-99m-mercaptoacetyltriglycine diuretic renography at two different time points (timepoint 1 and timepoint 2). Data were analyzed at local centers and at the study center and were collected in an internet-based database system. Tissue tracer transit was determined for each diuretic renography, inter-observer variation for tissue tracer transit and standard parameters for judgement of differential renal function development were assessed. Thirty-seven patients were analyzed. Median age was 11 weeks (7-15) at timepoint 1 and 26 weeks (19-33) at timepoint 2. A delayed tissue tracer transit at timepoint 1 was not associated with deterioration of differential renal function at timepoint 2 in both, locally (10/37 cases) and centrally (4/37) analyzed cases. However, sensitivity and specificity were poor. The intraclass correlation coefficient comparing local and central findings of tissue tracer transit and renal drainage demonstrated poor or fair agreement. Analysis of standard parameters for differential renal function development revealed a prognostic value only for the dichotomized anteroposterior renal pelvic diameter (APD, p=0.03, 95%-CI 1.2-22.2). Regarding the primary endpoint of our study, we could not confirm the hypothesis that delayed tissue tracer transit reliably predicts a subsequent decline in differential renal function in the cohort of patients studied. Whether the low age of the patients, technical problems in the correct assessment of tissue tracer transit by the investigator in early infancy, the study design, or the parameter itself played a role is debated. In the presented setting tissue tracer transit was not useful as a predictive parameter for deterioration of differential renal function in infants with suspected unilateral ureteropelvic junction obstruction. Sensitivity and specificity of tissue tracer transit were not sufficient for risk stratification. Improved utility of tissue tracer transit as a marker might be achieved using a different study setting.

Patient-specific distractors for customized mandibular distraction osteogenesis to relieve upper airway obstruction in infants with Pierre Robin sequence

The purpose of this article is to report the author’s technique for using patient-specific distractors for customized distraction osteogenesis of the mandible in patients with Pierre Robin sequence and upper airway obstruction. The advantages of virtual planning and patient-specific plates in other aspects of craniomaxillofacial surgery, such as orthognathic and reconstructive surgery, have been reported previously. Similar to patient-specific plates, the theorized advantages of patient-specific distractors in infants with Robin sequence and upper airway obstruction include increased accuracy, decreased operating time, and less morbidity to vital anatomic structures such as the inferior alveolar nerve and developing tooth buds. This technique is novel in using patient-specific distractors in the craniomaxillofacial skeleton.

Feeding Outcomes After Mandibular Distraction for Airway Obstruction in Infants.

Robin sequence is a congenital issue resulting in airway obstruction, difficulty feeding, and failure to thrive. Mandibular Distraction Osteogenesis is used to improve airway obstruction in these patients, but little data exists characterizing feeding outcomes following surgery. This study aims to evaluate feeding outcomes and weight gain following mandibular distraction for airway correction in infants. A single-center retrospective chart review was conducted, and patients under 12 months old who underwent mandibular distraction between December 2015 and July 2021 were included in the study. The presence of cleft palate, distance of distraction, and polysomnography results were recorded. The primary outcomes were the length of distraction, need for nasogastric tube or G-tube at discharge, time lapsed to achieve full oral feeds, and weight gain (kilogram). Ten patients met the criteria. Of those 10 patients, 4 were syndromic, 7 had a cleft palate, and 4 had a congenital cardiac diagnosis. The average length of stay postsurgery was 28 days. Eight patients achieved full oral feeds in an average of 65.6 days. Five patients required nasogastric tube or G-tube at discharge, with 3 of these patients later transitioning to full oral feeds. All patients gained weight 3 months postsurgery with an average of 0.521kg/mo. Patients who achieved full oral feeds gained an average of 0.549kg/mo. Patients with supplementation gained an average of 0.454kg/mo. All patients demonstrated improvement in airway obstruction with an average postoperative apnea hypopnea index of 1.64. Further investigation is necessary to identify challenges seen in feeding after mandibular distraction osteogenesis and improve care.

A Prospective Clinical Evaluation of Adhesive Small Bowel Obstruction in Infants and Children

Background: Adhesive small bowel obstruction is a significant cause of postoperative morbidity in children. There are limited studies on the epidemiology and scope of conservative management for adhesive small bowel obstruction in children. The purpose of this study was to determine the presentation, risk factors, and management, including the role of Gastrografin, for adhesive small bowel obstruction in children. Methods: Between June 2015 and June 2020, 90 patients with an adhesive small bowel obstruction presented to our pediatric surgery department. Out of these, 10 patients underwent upfront surgery and were excluded, while the rest were put on conservative treatment. Patients who failed to improve after 24 hours of conservative management in the absence of signs of strangulation were administered Gastrografin. Patients were evaluated clinically and radiologically to determine the resolution of the obstruction. Results: The mean age was 9.04 ± 3.89 with sex a ratio of 2.6:1. Vomiting was the most symptom (90% cases), followed by pain abdomen (87.5%). Appendectomy (50%) and enterotomy for worm obstruction (17.5%) were the most common previous surgical procedures leading to acute small bowel obstruction. Recurrent obstruction was seen in 7.5% of the cases. Thirty eight (47.5%) patients were successfully managed conservatively by standard decompression therapy. Oral administration of Gastrografin successfully resolved the obstruction in 43% patients who failed standard decompression therapy, whereas 24 (30%) patients with persistent obstruction required laparotomy. Conclusion: Adhesive small bowel obstruction is a common surgical emergency in children. It can occur at any age and after laparotomy for any surgical condition; however, history of appendectomy is associated with high incidence of adhesion obstruction. Vomiting and abdominal pain are constant symptoms. Conservative management with standard decompressive therapy followed by using water-soluble contrast agents (Gastrografin) is a safe and effective approach in managing adhesion obstruction in selected children without signs of bowel ischemia.

The Clinical Features and Risk Factors of Subglottic Cysts in Children: A Clinical Experience Using the Spontaneous Respiration Technique.

Subglottic cysts (SGCs) are a rare cause of respiratory distress resulting from upper airway obstruction in infants and young children. Risk factors other than prematurity with a history of endotracheal intubation have not yet been well elucidated. Therefore, we aimed to describe the clinical features and analyze the risk factors of SGCs. We conducted a retrospective review of medical records of pediatric patients who underwent marsupialization for SGCs between January 2017 and March 2022. These records were then compared with those of controls with a history of neonatal intubation, with a case-to-control ratio of 1:3. Eleven patients (eight boys and three girls) diagnosed with SGCs and 33 control patients (26 boys and seven girls) were included. All patients had a history of premature birth and neonatal intubation. Symptoms of SGCs appeared at a mean age of 8.2 months (range, 1-14 months) after extubation. The mean duration of intubation was 21.5 days (range, 2-90 days), and the intubation period was longer in patients with SGCs than in controls (21.5±24.8 days vs. 5.3±7.1 days; P<0.001). Furthermore, gestational age (28.3±4.2 weeks vs. 33.8±4.4 weeks; P=0.001) and birth weight (1,134.1±515.1 g vs. 2,178.2±910.1 g; P=0.001) were significantly lower in patients with SGCs than in controls. Multivariable analysis identified the intubation period as an independent risk factor. This study showed that gestational age, birth weight, and the intubation period were significantly associated with the development of SGCs. Pediatric patients presenting with progressive dyspnea who have the corresponding risk factors should undergo early laryngoscopy for the differential diagnosis of SGC.
