Objective: Patients with congenital malformations (CMs) of the gastrointestinal tract (GIT) have a very high mortality. However, the literature on the factors associated with mortality in these patients is scarce in sub-Saharan Africa. The aim of this study is to identify independent risk factors for mortality in patients with CMs of the GIT at our pediatric surgical department.
Methods: We conducted a retrospective analysis of cases with CMs of the GIT managed at a tertiary center from 2018 to 2021. Patients were subdivided into two groups based on the outcomes, and variables with a significant difference were analyzed by logistic regression.
Results: Our review included 226 patients, 63 of whom died (27.88%). Patient age ranged from 0 to 15 years. Taking into account statistical significance, mortality was more frequent in neonates than in older patients (57.30% vs 6.15%), in patients coming out of the Dakar area than in those from the Dakar area (43.75% vs 19.18%), in patients with abnormal prenatal ultrasound than in those with normal ultrasound (100% vs 26.67%), in premature children than in those born at term (78.57% vs 21.87%), in patients with an additional malformation than in those with an isolated malformation (69.23% vs 25.35%), and in those with intestinal, esophageal, duodenal and colonic atresia than in those with other diagnoses (100%, 89%, 56.25% and 50%, respectively). Referred patients died more than those who changed hospitals or came from home (55.29% vs 25% and 9.09%, respectively). On multivariable logistic regression, two independent factors of mortality were identified: presence of associated malformation [odds ratio (OR)=13.299; 95% Confidence interval (CI) 1.370 to 129.137] and diagnosis of esophageal atresia (OR=46.529; 95% CI 5.828 to 371.425).
Conclusion: The presence of an associated malformation or diagnosis of esophageal atresia increases mortality in patients with CMs of the GIT in our environment.
目的:胃肠道先天性畸形(CMs)患者的死亡率很高。然而,在撒哈拉以南非洲,关于这些患者死亡率相关因素的文献很少。本研究的目的是确定我们儿科外科GIT CMs患者死亡率的独立危险因素。方法:回顾性分析2018年至2021年在某三级中心管理的GIT CMs病例。根据结果将患者再分为两组,对差异显著的变量进行logistic回归分析。结果:纳入226例患者,其中63例死亡(27.88%)。患者年龄0 ~ 15岁。考虑到统计学意义,新生儿死亡率高于老年患者(57.30% vs 6.15%),达喀尔地区出生的患者死亡率高于达喀尔地区出生的患者死亡率(43.75% vs 19.18%),产前超声异常患者死亡率高于正常超声患者死亡率(100% vs 26.67%),早产儿死亡率高于足月新生儿死亡率(78.57% vs 21.87%)。附加畸形患者比孤立畸形患者(69.23% vs 25.35%),肠、食管、十二指肠和结肠闭锁患者比其他诊断的患者(分别为100%、89%、56.25%和50%)。转诊患者的死亡率高于转院或回家的患者(分别为55.29%比25%和9.09%)。在多变量logistic回归中,确定了两个独立的死亡因素:相关畸形的存在[优势比(OR)=13.299;95%可信区间(CI) 1.370 ~ 129.137)和食管闭锁的诊断(OR=46.529;95% CI 5.828 ~ 371.425)。结论:在我们的环境中,伴有相关畸形或诊断为食管闭锁的胃肠道CMs患者死亡率增高。

Background: Congenital anomalies are major causes of morbidity and mortality in children under 5 years of age and make a significant contribution to the surgical burden of diseases. Most anomalies have multifactorial causes and commonly affect the central nervous, cardiovascular, gastrointestinal and musculoskeletal systems. Countries with improved pediatric surgical care have shown dramatic reductions in morbidity and mortality rates. The aim of this study was to analyze the pattern of congenital anomalies presenting in our surgical departments in patients under 5 years of age.
Methods: A retrospective descriptive study was done. Data were obtained from clinical records of patients under 5 years of age, who underwent surgical correction of their congenital anomalies between 2017 and 2021. Analysis was done to identify the proportion of congenital anomalies managed in our setting.
Results: Congenital anomalies contributed 4.6% of overall surgical burden. Totally, 822 patients with congenital anomalies were included for analysis. The most commonly diagnosed congenital anomaly was inguinal hernia, followed by hydrocephalus, neural tube defects and cleft lips. The most commonly affected system was the central nervous system, anterior abdominal wall, orofacial and digestive system in decreasing order of frequency. Most of our patients presented outside the neonatal period (84.4%), and few (16.1%) had more than one system affected. Male children comprised 64%.
Conclusions: Delayed presentation of children with congenital anomalies is still a significant problem in our area. Prevention through nutritional supplementation and antenatal screening is crucial. The true epidemiology of congenital anomalies in northern Tanzania is still obscure.

Objective: To investigate the expression of Smad3 (mothers against decapentaplegic homolog 3) protein in postnecrotizing enterocolitis stricture and its possible mechanism of action.
Methods: We used immunohistochemistry to detect the expression characteristics of Smad3 and nuclear factor kappa B (NF-κB) proteins in human postnecrotizing enterocolitis stricture. We cultured IEC-6 (crypt epithelial cells of rat small intestine) in vitro and inhibited the expression of Smad3 using siRNA technique. Quantitative PCR, western blotting, and ELISA were used to detect the changes in transforming growth factor-β1 (TGF-β1), NF-κB, tumor necrosis factor-α (TNF-α), vascular endothelial growth factor (VEGF), and zonula occludens-1 (ZO-1) messenger RNA (mRNA) and protein expressions in IEC-6 cells. CCK8 kit and Transwell cellular migration were used to detect cell proliferation and migration. Changes in epithelial-mesenchymal transition (EMT) markers (E-cadherin and vimentin) in IEC-6 cells were detected by immunofluorescence technique.
Results: The results showed that Smad3 protein and NF-κB protein were overexpressed in narrow intestinal tissues and that Smad3 protein expression was positively correlated with NF-κB protein expression. After inhibiting the expression of Smad3 in IEC-6 cells, the mRNA expressions of NF-κB, TGF-β1, ZO-1, and VEGF decreased, whereas the mRNA expression of TNF-α did not significantly change. TGF-β1, NF-κB, and TNF-α protein expressions in IEC-6 cells decreased, whereas ZO-1 and intracellular VEGF protein expressions increased. IEC-6 cell proliferation and migration capacity decreased. There was no significant change in protein expression levels of EMT markers E-cadherin and vimentin and also extracellular VEGF protein expression.
Conclusions: We suspect that the high expression of Smad3 protein in postnecrotizing enterocolitis stricture may promote the occurrence and development of secondary intestinal stenosis. The mechanism may be related to the regulation of TGF-β1, NF-κB, TNF-α, ZO-1, and VEGF mRNA and protein expression. This may also be related to the ability of Smad3 to promote epithelial cell proliferation and migration.

Background: Pediatric surgical practice lags behind medicine in presence and use of evidence, primarily due to time constraints of using existing tools that are not specific to pediatric surgery, lack of sufficient patient data and unstructured pediatric surgery training methods.
Method: We developed, disseminated and tested the effectiveness of an evidence-based resource for pediatric surgeons and researchers that provides brief, informative summaries of quality-assessed systematic reviews and meta-analyses on conflicting pediatric surgery topics.
Results: Responses of 91 actively practicing surgeons who used the resource were analysed. The majority of participants found the resource useful (75%), improved their patient care (66.6%), and more than half (54.2%) found it useful in identifying research gaps. Almost all participants reported that the resource could be used as a teaching tool (93%).
Conclusion: Lack of awareness of the resource is the primary barrier to its routine use, leading to potential calls for more active dissemination worldwide. Users of the Canadian Association of Paediatric Surgeons Evidence-Based Resource find that the summaries are useful, identify research gaps, help mitigate multiple barriers to evidence-based medicine, and may improve patient care.

Background: Pediatric acute fulminant myocarditis (AFM) is a very dangerous disease that may lead to acute heart failure or even sudden death. Previous reports have identified some prognostic factors in adult AFM; however, there is no such research on children with AFM on venoarterial extracorporeal membrane oxygenation (VA-ECMO). This study aimed to find relevant prognostic factors for predicting adverse clinical outcomes.
Methods: A retrospective analysis was performed in an affiliated university children's hospital with consecutive patients receiving VA-ECMO for AFM from July 2010 to November 2020. These children were classified into a survivor group (n=33) and a non-survivor group (n=8). Patient demographics, clinical events, laboratory findings, and electrocardiographic and echocardiographic parameters were analyzed.
Results: Peak serum creatinine (SCr) and peak creatine kinase isoenzyme MB during ECMO had joint predictive value for in-hospital mortality (p=0.011, AUC=0.962). Based on multivariable logistic regression analysis, peak SCr level during ECMO support was an independent predictor of in-hospital mortality (OR=1.035, 95% CI 1.006 to 1.064, p=0.017, AUC=0.936, with optimal cut-off value of 78 μmol/L).
Conclusion: Tissue hypoperfusion and consequent end-organ damage ultimately hampered the outcomes. The need for left atrial decompression indicated a sicker patient on ECMO and introduced additional risk for complications. Earlier and more cautious deployment would likely be associated with decreased risk of complications and mortality.
背景:小儿急性暴发性心肌炎(AFM)是一种非常危险的疾病,可导致急性心力衰竭甚至猝死。以前的报告已经确定了成人AFM的一些预后因素;然而,对AFM患儿进行静脉动脉体外膜氧合(VA-ECMO)的研究尚未见。本研究旨在寻找预测不良临床结果的相关预后因素。方法:回顾性分析2010年7月至2020年11月在某附属大学儿童医院连续接受VA-ECMO治疗AFM的患者。这些儿童被分为幸存者组(n=33)和非幸存者组(n=8)。分析患者人口统计学、临床事件、实验室结果、心电图和超声心动图参数。结果:ECMO时血清肌酐(SCr)峰值和肌酸激酶同工酶(MB)峰值对院内死亡率具有联合预测价值(p=0.011, AUC=0.962)。多变量logistic回归分析显示,ECMO支持期间SCr峰值水平是院内死亡率的独立预测因子(OR=1.035, 95% CI 1.006 ~ 1.064, p=0.017, AUC=0.936,最佳临界值为78 μmol/L)。结论:组织灌注不足和由此引起的终末器官损伤最终影响了预后。左心房减压的需要表明患者在ECMO上病情较重,并引入了并发症的额外风险。更早和更谨慎的部署可能会降低并发症和死亡率的风险。

Background: Intradiaphragmatic extralobar pulmonary sequestration (IDEPS) is a rare type of pulmonary sequestration (PS). The purpose of this study is to assess diagnosis and operative treatment of IDEPS.
Methods: Patients with PS who were diagnosed and treated in our center from January 2015 to December 2020 were analyzed retrospectively to identify patients with IDEPS.
Results: Totally, 215 patients with PS were treated surgically, including 10 cases with IDEPS. Prenatal ultrasounds and postnatal-enhanced CT showed the presence of IDEPS in four cases and in seven cases, respectively. The three-dimensional (3D) reconstruction software was performed perfectly to identify the location of the lesions in 10 cases. The surgeries were performed smoothly by laparoscopic surgery in one case, video-assisted thoracic surgery (VATS) in five cases and Da Vinci robot-assisted thoracoscopic surgery (DVRATS) in four cases. In the VATS group, the average operative duration, intraoperative blood loss volume, length of stay after operation, and postoperative thoracic catheter indwelling duration were 48 min, 3.8 mL, 6.4 days and 2.2 days, respectively. That of the DVRATS group were 80 min, 3.5 mL, 4.3 days and 1.5 days, respectively. No side effects had appeared.
Conclusions: The 3D reconstruction software was proven to be capable in assisting the assessment of IDEPS. We suggested early surgery to treat IDEPS, and the best path was accessing the mass from the chest. Both DVRATS and VATS for the treatment of an IDEPS are safe, feasible, and effective. Furthermore, DVRATS provides a 3D magnified view, more flexibility and precision.

Objective: This study aimed to evaluate the predictive value of platelet volume indices (PVI), such as mean platelet volume (MPV), platelet distribution width (PDW), and plateletcrit (PCT), as prognostic indicators of testicular viability in torsion patients with steady-state sickle cell anemia (SCA) who underwent surgical exploration.
Methods: Forty-eight patients with SCA with testicular torsion and 46 male control subjects were enrolled in the study. All patients underwent scrotal color Doppler ultrasonography before surgery, and PVI (MPV, PDW, and PCT) values were measured in all participants. Symptom duration and testicular volume were also recorded.
Results: The testicular salvage rate in patients with SCA was 73% after surgery. Analyses showed that MPV, PDW, and PCT values were significantly higher in torsed SCA as compared with controls (p<0.05). Orchiectomy in patients with SCA showed significantly higher MPV, PDW, and PCT values than the orchiopexy group (p<0.05). The MPV values of orchiectomy patients showed a higher significant cut-off of ≥11.5 fL, which is higher than in torsed patients without SCA, as an indicator of testis survival. PDW also demonstrated a higher significant cut-off of ≥12.7 fL for detorsion outcomes in patients with SCA. Symptom duration of less than 7 hours was also significantly correlated with orchiopexy (p≤0.001). Univariate analysis showed that higher MPV, increased PDW, and symptom duration were indicative of the outcome of testicular detorsion in SCA. Multivariable analysis showed that increased PDW and symptom duration are prognostic parameters for testicular viability in SCA.
Conclusion: Increased PDW and symptom duration can be used as parameters for predicting testicular detorsion outcomes in patients with steady-state SCA.

Objective: Infantile hypertrophic pyloric stenosis (IHPS), which causes gastric outlet obstruction and hypochloremic hypokalemic metabolic alkalosis, could pose a risk of postoperative apnea in patients. The aim of this study is to evaluate the incidence of postoperative apnea in babies admitted to a tertiary-level pediatric surgical center in Milano, Italy with diagnosis of IHPS in 2010-2019. The secondary objective is to evaluate the risk factors for postoperative apnea.
Methods: This is a single-center, retrospective, observational cohort study. All patients admitted to our institution with diagnosis of IHPS during the study period were enrolled. Demographic and surgical variables, along with blood gas parameters, were obtained from the population. Postoperative apnea was defined as a respiratory pause longer than 15 s or a respiratory pause lasting less than 15 s, but associated with either bradycardia (heart rate <120 per minute), desaturation (SatO2 <90%), cyanosis, or hypotonia. Occurrence was obtained from nursing charts and was recorded as a no/yes dichotomous variable.
Results: Of 122 patients, 12 (9.84%) experienced apnea and 110 (90.16%) did not. Using univariate analysis, we found that only postoperative hemoglobin was significantly different between the groups (p=0.03). No significant multivariable model was better than this univariate model for prediction of apnea.
Conclusions: Postoperative anemia, possibly due to hemodilution, increased the risk of postoperative apnea. It could be hypothesized that anemia can be added as another apnea-contributing factor in a population at risk due to metabolic changes.

Background: Multiple chalazia are common in children, and many are treated by surgery. However, the distribution of different types of multiple chalazia has not been studied. This research aimed to investigate the location and number of multiple chalazia in pediatrics who need surgical treatments.
Methods: Patients with multiple chalazia treated by incision and curettage surgery (I&C) in a tertiary children's hospital between June and December 2016 were reviewed. Demographic data, locations, and numbers of chalazia were recorded. Data were analyzed using generalized linear models of the counts and the occurrences of chalazia. Hypotheses were tested using likelihood ratio tests appropriate for each type of data.
Results: The study included 128 subjects, most of which were 1-3 years old. The majority of patients had bilateral chalazia (95.3%), and the proportions of patients with internal, external, and marginal chalazion differed dramatically (99.2%, 61.7%, and 2.3%, respectively). The number of internal and external chalazia did not vary significantly with gender, age, or residence of the patients. Internal chalazia were located more frequently in the upper lids (p<0.001). External chalazia showed no preference of localization. The average number of internal chalazia in each eyelid did not relate to the presence of external chalazia.
Conclusions: Multiple chalazia are common among younger children in southeast China. The anatomical distribution varies depending on the type of chalazion. Multiple chalazia often occur bilaterally and internally. If doctors are more aware of the anatomical distribution of chalazia, this might result in a higher success rate of I&C.

Objectives: The aims of the present study were to explore the causes of minimally invasive surgical ventricular septal defect (VSD) closure failure under transesophageal echocardiography guidance and thus to improve the success rate of surgical VSD closure.
Methods: From January 2015 to December 2019, 522 children with VSD underwent minimally invasive surgical closure. Nineteen procedures (3.64%) were unsuccessful. The failure causes, VSD locations and surgical incision approaches were retrospectively analyzed.
Results: Among the 19 patients (3.64%) with unsuccessful outcomes, 18 were switched to cardiopulmonary bypass (CPB) surgery, and 1 was closed successfully using an occlusion device a year later. The causes of failure included occlusion device shedding or shifting (n=6), failure of the guidewire (or the sheath) to pass through a small defect (n=5), device-related valve regurgitation (n=4), significant residual shunt (n=2), ventricular fibrillation (n=1), and continuous sharp blood pressure decreases (n=1). Patients with high VSD had a slightly higher failure rate than those with perimembranous VSD (p=0.049), and its key reason is the high proportion of occlusion device shedding or shifting (p=0.001). No significant difference in the failure rate was found between patients with different surgical incision approaches.
Conclusions: Minimally invasive surgery has a high success rate for perimembranous VSDs. Occlusion device shedding or shifting is the most common cause of failure. The shedding or shifting risk of eccentric occlusion devices being used only for high VSDs is much greater than that of concentric occlusion devices being used for perimembranous VSDs, which increases the risk of conversion to CPB surgery for high VSDs.
