RESUMEN
AIM: Laparoscopic gastrostomy is a frequently performed procedure in children requiring long-term enteral nutrition. The role of prophylactic anti-reflux surgery during gastrostomy placements is controversial. The current study aims to evaluate the role of prophylactic anti-reflux procedures during gastrostomy placement. METHODS: A retrospective single-center analysis of all children without reflux receiving laparoscopic gastrostomy from January 2005 through December 2021 was performed. Demographics and clinical outcomes were compared between patients receiving gastrostomy placement alone and patients receiving gastrostomy with prophylactic anti-reflux surgery. RESULTS: A total of 79 patients had a confirmed absence of reflux by a 24-h pH/impedance study before operation. Thirty-six of these patients underwent prophylactic anti-reflux surgery (PAR) while 43 received gastrostomy (PG) alone. The operative time and conversion rate were significantly higher in the PAR group (140.5 ± 67.5 vs. 80.2 ± 66.8 min, p = 0.0001 and 8.3% vs. 0%, p = 0.04). There were no major complications in either group. De novo reflux was detected in five patients (11.6%) in the PG group. None of these patients progressed to require anti-reflux surgery. CONCLUSION: The occurrence of de novo reflux after laparoscopic gastrostomy was low and could be managed without anti-reflux surgery. A routine pre-operative pH study is helpful for appropriate patient selection to avoid unnecessary anti-reflux surgery, which lengthens operative time and increases the conversion rate.

INTRODUCTION: Trauma is the leading cause of paediatric mortality and morbidity. Stay-home regulations for coronavirus disease 2019 (COVID-19) reportedly changed trauma severity, yet data from Hong Kong were lacking. This study examined Hong Kong's spectrum of paediatric trauma and addressed knowledge gaps concerning epidemiological changes during COVID-19. METHODS: Children with traumatic injuries who attended a tertiary trauma centre from January 2010 to March 2022 were included in this retrospective, cross-sectional study. We analysed demographic and clinical data and conducted unadjusted bivariate analyses of injury patterns before and after the pandemic. RESULTS: In total, 725 children attended the Accident and Emergency Department due to trauma, 585 before and 140 during COVID-19. The male-to-female ratio was 1.84:1. The 90-day trauma-related mortality was 0.7%. The overall Injury Severity Score was 3.52 ± 5.95. The paediatric trauma incidence was similar before and after social-distancing policies (both 5.8 cases monthly). Gender, ISS distribution, intensive care unit stay length, and hospital stay length values were similar (p > 0.05). Trauma call activation (8.4% vs. 5.7%, p = 0.002) and road traffic accidents (10.6% vs. 5.7%, p = 0.009) significantly decreased, yet younger-patient injuries (< 10 years old; 85.7% vs. 71%, p < 0.001), burns (28% vs. 45.7%, p < 0.001), and domestic injuries (65.5% vs. 85.7%, p < 0.001) significantly increased. No significant self-harm, assault, or abuse increases were found. CONCLUSIONS: The paediatric trauma incidences were similar before and during the pandemic. However, domestic and burn injuries significantly increased, highlighting the importance of injury prevention.

BACKGROUND: Laparoscopic inguinal hernia repair is one of the procedures most commonly performed by paediatric surgeons. Current research on the learning curve for laparoscopic hernia repair in children is scarce. This study aims to evaluate the clinical outcome and learning curve of laparoscopic intra-corporeal inguinal hernia repair in children. METHODS: A retrospective single-centre analysis of all paediatric patients who underwent laparoscopic intra-corporeal inguinal hernia repair between 2010 and 2019 was performed. The clinical outcomes were analysed. The data on the achievement of the learning curve by surgical trainees were evaluated with the CUSUM technique, focusing on operative time. RESULTS: There were 719 patients with laparoscopic intra-corporeal inguinal hernia repair (comprising 1051 sides) performed during the study period. The overall ipsilateral recurrence rate was 1.8% without other complications detected. CUSUM analysis showed that there were 3 phases of training, for which the trainees underwent initial learning phase (Phase 1) for the first 7 cases. After mastering of the skills and extrapolating the skills to male patients with smaller body size (Phase 2), they then achieved performance comparable to that of the senior surgeons after 18 procedures (Phase 3). CONCLUSIONS: 18 procedures seem to be the number required to reach the learning curve plateau in terms of operative time by surgical trainees. The clinical outcomes show that laparoscopic intra-corporeal inguinal hernia repair is a safe and transferrable technique, even in the hands of trainees, with adequate supervision and careful case selection. It also provides skill acquisition for minimally invasive surgery.

PURPOSE: We aimed to compare the outcomes of primary anastomosis (PA) and enterostomy as treatments for intestinal atresia in neonates to identify the factors influencing the choice of modality. METHODS: We conducted a retrospective single-centre analysis of all neonates with intestinal atresia between 2000 and 2020 and measured the clinical outcomes. We performed logistic regression to identify factors that influenced the choice of surgical approach. RESULTS: Of 62 intestinal atresia neonates, 71% received PA. There were no significant differences in gestation, gender, age at operation, birth weight, or body weight at operation between the PA and enterostomy groups. PA reoperation was not required for 78% of patients, and the PA group had shorter hospital stays. Complications, operative time, duration on parenteral nutrition, time to full enteral feeding were comparable in both groups. Upon multivariate regression analysis, surgeons favoured PA in proximal atresia [Odds ratio (OR) 38.5, 95% Confidence Interval (CI) 2.558-579] while enterostomy in smaller body size [OR 2.75, CI 0.538-14.02] and lower Apgar score [OR 1.1, CI 0.07-17.8]. Subgroup analysis in these patient groups demonstrated comparable outcomes with both surgical approaches. CONCLUSION: Both surgical approaches achieved comparable outcomes, but PA was associated with short hospital stays and the avoidance of stoma-related complications, and reoperation was generally not required. This surgical approach was suitable for patients with proximal atresia, but enterostomy remained a sensible choice for patients with smaller body sizes and lower Apgar scores.

AIM: This study reviewed the experience of a tertiary paediatric surgery and obstetric centre on prenatal counselling of congenital surgical anomalies and to explore the role of paediatric surgeons on perinatal outcomes of antenatally detected anomalies. METHODS: A retrospective analysis of all antenatal consultations and subsequent medical records after birth were performed between 2009 and 2018. Data including timing of consultations, gestations at birth, birthweight, impact on obstetrics management, neonatal mortality and need of surgery were included. RESULTS: A total of 256 fetuses were diagnosed to have congenital surgical anomalies on antenatal ultrasound. The most common were urogenital (31%) and thoracic (30%) anomalies. Twelve of the 256 (4.7%) had multiple anomalies. The mean gestation at referral was 23 ± 5 weeks. The majority (85.4%) were born at term. Mode and timing of delivery was altered in 7% of patients. Four received fetal intervention after surgical consultation. Termination of pregnancy rate was 5.4% (n = 14). Neonatal death was reported in 7.8% of the cohort. CONCLUSION: Congenital surgical anomalies had a significant impact on perinatal outcome as well as morbidity in later infancy and childhood. A multidisciplinary approach in managing pregnancy with these anomalies should be implemented. Combined-specialty consultations and counselling deliver valuable information for parents.

BACKGROUND: Congenital diaphragmatic hernia (CDH) is a developmental defect that causes herniation of abdominal organs into the thoracic cavity with significant morbidity. Thoracoscopic repair of CDH is an increasingly prevalent yet controversial surgical technique, with limited long-term outcome data in the Asian region. The aim of this study was to compare open laparotomy versus thoracoscopic repair of CDH in paediatric patients in a major tertiary referral centre in Asia. METHODS: We performed a retrospective analysis of neonatal patients who had open laparotomy or thoracoscopic repair for CDH in our institution between July 2002 and November 2021. Demographic data, perioperative parameters, recurrence rates and surgical complications were analysed. RESULTS: 64 patients were identified, with 54 left sided CDH cases. 33 patients had a prenatal diagnosis and 35 patients received minimally invasive surgical repair. There was no significant difference between open and minimally invasive repair in recurrence rate (13 % vs 17 %, P = 0.713), time to recurrence (184 ± 449 days vs 81 ± 383 days, P = 0.502), or median length of ICU stay (11 ± 14 days vs 13 ± 15 days, P = 0.343), respectively. Gastrointestinal complications occurred in 7 % of neonates in the open group and none in the thoracoscopic group. Median follow-up time was 9.5 years. CONCLUSIONS: This study is a large congenital diaphragmatic hernia series in Asia, with long term follow-up demonstrating no significant difference in recurrence rate, time to recurrence or median length of ICU stay between open and minimally invasive repair, suggesting thoracoscopic approach is a non-inferior surgical option with avoidance of gastrointestinal complications compared to open repair. TYPE OF STUDY: Retrospective Cohort Study.

INTRODUCTION: Postoperative ileus is a common occurrence among children undergoing major operations, including gastrointestinal and spinal surgeries. Preliminary evidence in adults suggests that chewing gum plays a role in accelerating the return of postoperative gastrointestinal function. However, evidence is scarce in the paediatric population. The aim of this study was to investigate whether chewing gum has benefits for children. METHODS: We searched PubMed, Medline, Embase, and Cochrane Trials databases for randomised controlled trials that compare gum chewing with standard care after elective surgery in children from 1st Jan 2005 to 31st July 2021. We assessed the identified trials for quality and performed a systematic review and meta-analysis in accordance with PRISMA and registered in PROSPERO (CRD42022358801). The main outcome measures examined were time to flatus and stool postoperatively, time to tolerate oral intake, and length of hospital stay, which were analysed using fixed effects models. We also examined clinical complication rates and postoperative pain control. RESULTS: We included six eligible trials, with a total of 357 enrolled patients. The intervention was well tolerated without complications. There was no significant difference in time to flatus (-2.86 h; 95 % CI: -6.2 to 0.47 h, p = 0.09), time to stool (-6.39 h; 95 % CI: -13.9 to 1.2 h, p = 0.1), time to tolerate oral intake (-0.03 days; 95 % CI: -0.15 to 0.1 days, p = 0.68), and length of hospital stay (0.08 days; 95 % CI: -0.07 to 0.22 days, p = 0.29). Postoperative pain control (opioid consumption, pain score, nausea score) was similar in both groups (p > 0.05). CONCLUSION: Current evidence demonstrates that gum chewing is not associated with earlier postoperative gastrointestinal recovery in children. Future adequately powered and well-designed trials are necessary to evaluate any clinical benefit of chewing gum for children and whether it could result differences in healthcare satisfaction. LEVEL OF EVIDENCE: I.

BACKGROUND: Short bowel syndrome (SBS) is a rare but serious form of organ failure, and patients with SBS depend on total parenteral nutrition (PN) to maintain growth and development. The present study aimed to evaluate the experiences and outcomes of children with SBS managed by a multidisciplinary intestinal rehabilitation programme in a tertiary paediatric centre. METHODS: A retrospective single-centre analysis of all paediatric patients with a clinical diagnosis of SBS between 2001 and 2022 was performed. Clinical outcomes and their predictors were extracted and analysed. RESULTS: Of the 64 children included in the study, 43 (67%) had extensive necrotising enterocolitis. The median bowel length was 45 cm (interquartile range (IQR) = 18-65) and 18.9% (IQR = 10-28.5) of the expected length based on age. Over a mean follow-up period of 8.9 years, 57 patients (89%) survived, and 50 (78%) weaned off PN. The presence of intestinal failure-associated liver disease (IFALD) (OR = 6.375, p = 0.02) and patients managed before the introduction of fish oil-based PN in 2007 (OR = 5.895, p = 0.001) were significant predictors of mortality. There was an overall improvement in survival over time (p = 0.003). Ultrashort bowel length was not associated with significantly higher mortality (OR = 1.1, p = 0.65) but was a poor prognostic factor for weaning off PN (OR = 3.57, p = 0.004). Among all patients who weaned off PN, two had bowel lengthening procedures and one received a glucagon-like peptide 2 (GLP-2) analogue. CONCLUSIONS: A multidisciplinary intestinal rehabilitation programme offers a comprehensive approach for patients with SBS and has been shown to be effective with favourable outcomes. Improvements in the choice of PN and the development of new treatment strategies potentially improved the survival and enteral autonomy of SBS patients. LEVEL OF EVIDENCE: III.
RESUMEN
INTRODUCTION: Intra-abdominal testis (IAT) remains a challenging and controversial subset within the management of cryptorchidism. While Fowler-Stephens orchidopexy (FSO) is still being advocated as the gold standard for the treatment of this entity, there is new and conflicting evidence on the comparative outcomes between single- or two-stage laparoscopic FSO (LFSO). The aim of the study is to investigate whether staging has benefits in children receiving LFSO. METHODS: We searched the PubMed, Medline, Embase, and Cochrane Trials databases for studies comparing single- with two-stage LFSO in children from January 1, 1995 to December 31, 2023. We assessed the identified studies for quality and performed a systematic review and meta-analysis in accordance with the Preferred Reporting of Systematic Reviews and Meta-Analyses. The main outcome measures examined were success rate (in terms of the scrotal position of the testis) and testicular atrophy, which were analyzed using fixed effect models. RESULTS: We included 17 eligible studies that involved a total of 499 operated testes. The overall success rates of single- and two-stage LFSO were 79.4 and 90.3%, respectively. The overall testicular atrophy rates of single- and two-stage LFSO were 17.3 and 11%, respectively. Fixed effect model analysis showed that two-stage LFSO is significantly superior to single-stage LFSO in overall success rate (odds ratio [OR: 2.57]; 95% confidence interval [CI]: 1.50-4.39, p = 0.0006) and testicular atrophy rate (OR: 0.48; 95% CI: 0.28-0.79, p = 0.004). There is no heterogeneity in the reports, and the funnel plot showed no publication bias. CONCLUSIONS: Two-stage LFSO remains the first choice of operation for children with a high IAT, with a significantly higher success rate and a lower testicular atrophy rate.
RESUMEN
Background: Thoracoscopy, which has an increasing role in the treatment of indexed neonatal surgical conditions, requires adequate training. To support this, the current study aimed to evaluate the feasibility and effectiveness of using live rabbit models in neonatal thoracoscopic skills training among paediatric surgeons. Methods: Following didactic lectures and demonstrations, the participants were given hands-on opportunities to perform thoracoscopic procedures. The feasibility and effectiveness of using live rabbit models in neonatal thoracoscopic skills training among paediatric surgeons were evaluated with pre-/post-course procedural confidence scores and a questionnaire. Results: This study included 13 paediatric surgeons-2 (15 %) males and 11 (85 %) females-who were evenly distributed. There were four basic surgical trainees, five higher surgical trainees and four fellows in paediatric surgery (mean surgical practice experience: 4.5 ± 3.7 years). Most had experience assisting paediatric (70 %) and neonatal (62 %) thoracoscopic surgery. Only 30 % had experience as the chief surgeon of paediatric thoracoscopic surgery, with none on neonates. Significant improvement was seen in procedural confidence as the assistant and chief surgeon of all procedures post-workshop. The surgeons rated the model positively. Conclusion: The procedural confidence level of paediatric surgeons improved significantly after workshop participation. This realistic and easily reproducible model can help perfect thoracoscopic skills. Therefore, its integration into paediatric surgical training would promote surgical skill proficiency and could improve surgeons' confidence in neonate operations.
RESUMEN
PURPOSE: To offer an up-to-date appraisal of the current status of enhanced recovery after surgery (ERAS) protocols in pediatric urology and to provide a guide for the clinical urologist. MATERIALS AND METHODS: We performed a comprehensive literature search and scoping review on ERAS protocols in pediatric urology using Pubmed (from 1946), Cochrane library, and MEDLINE to December 2021 with the terms ''enhanced recovery'', ''protocolised care'', ''post-operative protocol", ''fast-track surgery'' and ''pediatric urology". Studies were excluded if they did not include perioperative intervention related to urological procedures, no full-text available and in non-English language. RESULTS: To date, eight clinical studies (involving 1153 patients) have been published on ERAS protocols in pediatric urology. The patients involved ranged from neonates to adolescents, and the urological procedures included bladder augmentation, the Mitrofanoff procedure, laparoscopic pyeloplasty, laparoscopic nephrectomy, hypospadias repair, etc. Multidisciplinary components such as surgical and anesthetic considerations have been employed in ERAS protocols. The length of hospital stay was significantly lower in the ERAS groups with earlier enteral feeding resumption and return of bowel function in pediatric urology patients. The implementation of ERAS protocols does not result in higher complication and readmission rates; instead, some studies have even demonstrated a significant reduction in complication occurrence. CONCLUSION: ERAS is novel to pediatric urology with a limited scale of published data in the literature. Initial clinical studies revealed that ERAS appears to be efficacious in the field of pediatric urology. Further prospective studies formulating a standardized multimodal protocol are encouraged to better understand key components of ERAS and incorporate ERAS into clinical practice to optimize surgical outcomes for pediatric urology procedures.

INTRODUCTION: Laparoscopic inguinal hernia repair is a commonly performed procedure in children. Currently, monofilament polypropylene and braided silk are the two most frequently used materials. Studies have suggested more tissue inflammatory reactions with the use of multifilament non-absorbable sutures. However, little is known about the effects of suture materials on adjacent vas deferens. The aim of this experiment was to compare the effect of non-absorbable monofilament and multifilament sutures on vas deferens in laparoscopic hernia repair. METHODS: All animal operations were performed by a single surgeon under aseptic conditions and anaesthesia. Ten male Sprague Dawley rats were divided into two groups. In Group I, "hernia repair" was performed using 5.0 Silk. In Group II, polypropylene sutures (Prolene®; Ethicon, Somerville, N.J., USA) were used. All animals also received sham operations in the left groin as a control. After 14 days, the animals were euthanised and a segment of vas deferens just adjacent to the suture was excised for histological review by an experienced pathologist who was blind to the treatment groups of the respective specimens. RESULTS: The body sizes of the rats in each group were comparable. Group I had significantly smaller vas deferens than Group II (diameter: 0.2 vs. 0.6 ± 0.2, p = 0.005). Silk sutures appeared to cause more tissue adhesion than Prolene® sutures, as graded by blind assessors (adhesion grade: 2.8 ± 1.3 vs. 1.8 ± 0.8, p = 0.1), although this did not reach statistical significance. There was no significant difference in the histological fibrosis score and inflammation score. CONCLUSION: The only effect of non-absorbable sutures on vas deferens in this rat model was the reduced cross-sectional area of vas deferens and increased tissue adhesion when using silk sutures. However, there was no significant histological difference in inflammation or fibrosis caused by either material.

BACKGROUND Thyroid carcinoma showing thymus-like differentiation (CASTLE) is a rare disease entity. It arises from ectopic thymic tissue in the thyroid gland. Patients usually present with enlarging neck mass and hoarseness. CASE REPORT A 49-year-old man presented to our clinic with hoarseness and a right thyroid mass. Ultrasound showed a 6-cm right thyroid tumor and computer tomography confirmed invasion into the trachea. He received total thyroidectomy together with excision of one-third of the tracheal wall. No gross tumor was left behind. The tracheal defect was repaired using a pedicled right sternocleidomastoid muscle flap. He had a good recovery and was discharged 2 days after surgery. Histology revealed carcinoma showing thymus-like differentiation (CASTLE). The patient had regular follow-up and showed no clinical evidence of recurrence 18 months after surgery. CONCLUSIONS Thyroid carcinoma showing thymus-like differentiation (CASTLE) is a rare yet potentially extensive disease with favorable prognosis. Imaging, such as computed tomography (CT) and magnetic resonance imaging (MRI), is helpful in aiding diagnosis and operative planning. Surgical resection is currently the treatment of choice, with generally favorable outcomes. The role of adjuvant therapies such as radiotherapy and chemotherapy require further studies.
