Comparison of laparoscopic cholecystectomy in children at paediatric centres and adult centres: a systematic review and meta-analysis.

INTRODUCTION: Paediatric laparoscopic cholecystectomy (LC) is performed by both paediatric and adult surgeons. The aim of this review was to compare outcomes at paediatric centres (PCs) and adult centres (ACs). METHODS: A literature search was conducted, in accordance with PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines, for papers published between January 2000 and December 2020. Statistical analysis was performed using Stata® version 16 (StataCorp, College Station, TX, US). RESULTS: A total of 92 studies involving 74,852 paediatric LCs met the inclusion criteria. Over half (59%) of the LCs were performed at ACs. No significant differences were noted in the male-to-female ratio, mean age or mean body mass index between PCs and ACs. The main indications were cholelithiasis (34.1% vs 34.4% respectively, p=0.83) and biliary dyskinesia (17.0% vs 23.5% respectively, p<0.01). There was no significant difference in the median inpatient stay (2.52 vs 2.44 days respectively, p=0.89). Bile duct injury was a major complication (0.80% vs 0.37% respectively, p<0.01). Reoperation rates (2.37% vs 0.74% respectively, p<0.01) and conversion to open surgery (1.97% vs 4.74% respectively, p<0.01) were also significantly different. Meta-analysis showed no significant difference in overall complications (p=0.92). CONCLUSIONS: The number of LCs performed, intraoperative cholangiography use and conversion rates were higher at ACs whereas bile duct injury and reoperation rates were higher at PCs. Despite a higher incidence of bile duct injury at PCs, the incidence at both PCs and ACs was <1%. In complex cases, a joint operation by both paediatric and adult surgeons might be a better approach to further improve outcomes. Overall, LC was found to be a safe operation with comparable outcomes at PCs and ACs.

Post-urethroplasty complications in hypospadias repair: a systematic review and meta-analysis comparing polydioxanone and polyglactin sutures.

Background: Polyglactin (PG) and polydioxanone (PDS) sutures are extensively used based on the surgeon's preference. The development of post-reconstruction urethrocutaneous fistula (UCF) is variably attributed to the choice of suture material for urethroplasty. This meta-analysis compares complications of hypospadias repair using PG and PDS sutures. Methods: The systematic review and meta-analysis were performed as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The authors conducted thorough searches in databases including MEDLINE, EMBASE, CENTRAL, Scopus, Google Scholar, and clinical trial registries. Outcome measures included UCF, meatal stenosis, wound infection, urethral stricture, glans dehiscence, and overall complications. Quantitative analysis was used with fixed or random-effect models to find the pooled risk ratio and I2 heterogeneity. Results: The criteria for inclusion were met by five comparative studies with the inclusion of 1244 children altogether. Pooled analysis failed to show a statistically significant difference in the incidence of meatal stenosis, urethral stricture, wound infection, and total complications using PG and PDS sutures. However, it showed a reduction in the incidence of UCF with PDS suture hypospadias repairs (risk ratio=0.66, 95% CI 0.48 to 0.92). Conclusions: PDS sutures are associated with decreased incidence of UCF than PG after hypospadias repair. The incidence of meatal stenosis, urethral stricture, wound infection, and total complications was not affected by the type of suture material used for repair. Clinical implications: This meta-analysis suggests decreased incidence of UCF when PDS sutures are used for hypospadias repair which may impact the choice of suture material for repair. PROSPERO registration number: CRD42023409710.

Tubularized incised plate urethroplasty and grafted tubularized incised plate urethroplasty: systematic review, meta-analysis and trial sequential analysis.

Background: Hypospadias is one of the most common genital birth defects. There are around 300 various techniques available for the repair of hypospadias. This study aims to compare the reported outcomes of Tubularized incised plate urethroplasty (TIP) and Grafted TIP (GTIP) repair in children undergoing primary hypospadias repair. Methods: This meta-analysisadhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and we framed our research question using the population, intervention, control and outcomes format. We conducted comprehensive electronic searches across various databases, employing a Boolean search strategy with predefined search terms. Only randomized controlled trials (RCTs) were included for quantitative analysis. Results: Totally, 10 RCTs met our inclusion criteria for quantitative analysis. The results indicated that urethrocutaneous fistula, glans dehiscence, and stricture rates were comparable between the two groups. The incidence of meatal stenosis was found to be significantly lower in the GTIP group with a relative risk (RR) of 0.32 (95% confidence interval (CI) 0.15 to 0.67). Conclusion: The coucomes UCF, glans dehiscence, and stricture rates were comparable between the two groups. Notably, the incidence of meatal stenosis was found to be significantly lower in the grafted TIP group. In terms of operative time, our quantitative synthesis demonstrated that the TIP group had a shorter operative time than the GTIP group with significant heterogeneity.

Single dartos flap versus double dartos flap in hypospadias repair: A systematic review and meta-analysis with trial sequential analysis and fragility index.

INTRODUCTION: Hypospadias is a common congenital urogenital anomaly. Despite advancements in surgical techniques, still it presents challenges in management. An important aspect of hypospadias repair is the use of protective layers to cover neourethra. This review focuses on comparing the Single Dartos Flap (SDF) and Double Dartos Flap (DDF) techniques, used to cover the neourethra. These techniques differ in terms of the number of dartos layers used to cover the neourethra. METHODS: This systematic review, follows PRISMA guidelines, included six RCTs from PubMed/MEDLINE, Cochrane Library, Scopus, Web of Science, and CINAHL. Patients with hypospadias repair with use of SDF or DDF were analyzed for outcome, Urethrocutaneous fistula, meatal stenosis, glans dehiscence, penile torsion and cosmetic outcomes. Statistical analysis was done using Review Manager, with TSA and FI ensuring result robustness. RESULTS: Six studies met inclusion criteria, and risk of bias assessment indicated low risk across all domains. Meta-analysis results favored DDF over SDF for reducing urethrocutaneous fistula (RR 0.37, 95% CI 0.20-0.68) but showed no significant difference in meatal stenosis and glans dehiscence. DDF also associated with lower risk of penile torsion (RR 0.05, 95% CI 0.01-0.35). CONCLUSION: The systematic review, based on randomized controlled trials (RCTs), provides evidence supporting the use of DDF over SDF in hypospadias repair, particularly in distal hypospadias using the TIP procedure. The article emphasizes the potential advantages of DDF in reducing UCF but further robust evidence is needed to confirm these results based on the findings of TSA and FI.

Qualitative Exploration Toward the Development of a Parent-Rated Scale for Insomnia in Children with Autism Spectrum Disorder.

Toward the development of a new parent-rating for insomnia, this multi-site qualitative study explored sleep problems and related impacts in children with autism spectrum disorder (ASD) and their families. To ensure content validity of the measure, we conducted six focus groups with caregivers (N = 25) of 24 children (age 3 to 18 years) with ASD. Based on parent report, all children had a history of mild or greater insomnia. The focus group transcripts were systematically coded to identify major themes. Verbatim comments from caretakers were used to generate 134 candidate items. Further review by the research team and an expert panel followed by individual cognitive interviews with 12 parents reduced the item bank to 40. The thematic analysis of focus group transcripts identified 7 categories: (1) Trouble falling asleep; (2) trouble staying asleep; (3) early morning waking; (4) bedtime routines; (5) parental strategies for bedtime management; (6) impact of sleep problems on the child; and (7) impact of sleep problems on the family. The Flesch Kincaid Grade Level of the 40-item version was 7.2 (seventh grade reading level). Insomnia in children with ASD shares features in common with insomnia in the general pediatric population. However, perhaps owing to autistic features such as insistence on sameness, sensory sensitivities, communication impairments, insomnia in children with ASD appears to have unique behavioral manifestations. Content validity and item clarity of the 40-item bank were supported by expert panel review and cognitive interviews with caregivers of children with ASD.

Laparoscopic cholecystectomy in children: A systematic review and meta-analysis.

BACKGROUND: Laparoscopic cholecystectomy (LC) has become the procedure of choice for the removal of gallbladder within the paediatric population. The aim of this study was to perform a systematic review and meta-analysis of the literature spanning the last 20 years to understand the indications for and safety of LCs in children. METHODS: A comprehensive search of the published English language literature from January 2000 to June 2020 was done on PubMed, MEDLINE, and Google Scholar. RESULTS: In total, 76,524 LC cases were identified from 114 studies. 78.9% of the patients were female and average age was 12 years old. Associated haematological disorders were identified in 16% of cases. The commonest indication for LC was cholelithiasis (68.4% in 66 studies), followed by cholecystitis (59.2% in 53 studies). Median operating time was 77 min. Median hospital stay was 2 days. The overall postoperative complication rate was 3.4% Major complications included bile duct injury (0.4%) and intra- or post-operative bleeding (0.9%). The conversion rate to open procedure was 2%. When comparing post-operative outcomes between emergency and elective admissions, three papers lent themselves to meta-analysis demonstrating no significant difference (p = 0.42). There was no statistically significant difference in postoperative complication rate between "hot" and "cold" laparoscopic cholecystectomies (p = 0.6). CONCLUSION: This systematic review and meta-analysis is the largest collection of subjects on laparoscopic cholecystectomies in children. Laparoscopic cholecystectomy is a safe operation in children, with complication rates similar or comparable to the adult literature. Cholelithiasis, cholecystitis and biliary dyskinesia were the commonest indications for LC.

Quenching effect of oscillating potential on anisotropic resonant transmission through a phosphorene electrostatic barrier.

The anisotropy in resonant tunneling transport through an electrostatic barrier in monolayer black phosphorus either in presence or in absence of an oscillating potential is studied. Non-perturbative Floquet theory is applied to solve the time dependent problem and the results obtained are discussed thoroughly. The resonance spectra in field free transmission are Lorentzian in nature although the width of the resonance for the barrier along the zigzag (Г-Y) direction is too thinner than that for the armchair (Г-X) one. Resonant transmission is suppressed for both the cases by the application of oscillating potential that produces small oscillations in the transmission around the resonant energy particularly at low frequency range. Sharp asymmetric Fano resonances are noted in the transmission spectrum along the armchair direction while a distinct line shape resonance is noted for the zigzag direction at higher frequency of the oscillating potential. Even after the angular average, the conductance along the Г-X direction retains the characteristic Fano features that could be observed experimentally. The present results are supposed to suggest that the phosphorene electrostatic barrier could be used successfully as switching devices and nano detectors.

The need for Paediatric Emergency Laparotomy Audit (PELA) in the UK.

INTRODUCTION: The National Emergency Laparotomy Audit (NELA) has raised serious concerns about the processes of care and outcomes in adult emergency laparotomies in the UK. To date, no comparable data have been published for children. The aim of this study was to investigate the need for a similar audit in children. METHODS: Data were collected retrospectively following NELA guidelines. Results were analysed using QuickCalcs (GraphPad Software, La Jolla, CA, US). RESULTS: The study period spanned 7.5 years. A total of 161 patients were identified for inclusion in the audit. The median patient age was 2.8 years. Half (49%) of the cohort were deemed ASA (American Society of Anesthesiologists) grade ≥2. A history of previous abdominal surgery was noted in 37% of the patients. The median time from admission to operation was 15 hours. Over a third (39%) of the operations were performed out of hours. The most common indications for surgery comprised adhesive bowel obstruction (37%), intussusception (27%) and volvulus (9%).The median length of hospital stay was 8 days with the median postoperative stay being 6 days (NELA data 10.6 days). Half (51%) of the cases required intensive care following surgery. The 30-day mortality rate was 3.1%. The overall mortality rate was 4.3% (NELA data 16%). Patient care was led by a consultant surgeon in 100% of cases (NELA data 89%). CONCLUSIONS: This is the first study in children that provides baseline data about the standards of care and outcomes from a single centre paediatric emergency laparotomy audit. A larger study using data from multiple centres would be of great benefit.

The importance of social media for patients and families affected by congenital anomalies: A Facebook cross-sectional analysis and user survey.

BACKGROUND: We aimed to define characteristics and needs of Facebook users in relation to congenital anomalies. METHODS: Cross-sectional analysis of Facebook related to four congenital anomalies: anorectal malformation (ARM), congenital diaphragmatic hernia (CDH), congenital heart disease (CHD) and hypospadias/epispadias (HS/ES). A keyword search was performed to identify relevant Groups/Pages. An anonymous survey was posted to obtain quantitative/qualitative data on users and their healthcare needs. RESULTS: 54 Groups and 24 Pages were identified (ARM: 10 Groups; CDH: 9 Groups, 7 Pages; CHD: 32 Groups, 17 Pages; HS/ES: 3 Groups), with 16,191 Group members and 48,766 Page likes. 868/1103 (79%) of respondents were parents. Male:female ratio was 1:10.9. 65% of the users were 26-40years old. Common reasons for joining these Groups/Pages included: seeking support, education, making friends, and providing support to others. 932/1103 (84%) would like healthcare professionals (HCPs) to actively participate in their Group. 31% of the respondents felt that they did not receive enough support from their healthcare system. 97% of the respondents would like to join a Group linked to their primary hospital. CONCLUSIONS: Facebook Groups/Pages related to congenital anomalies are highly populated and active. There is a need for HCPs and policy makers to better understand and participate in social media to support families and improve patient care.

Thirty-days readmissions in pediatric surgery: The first U.K. experience.

INTRODUCTION: The aim of this study was to investigate readmissions within 30days of operation (ReAd) in the setting of a tertiary pediatric surgical practice in the UK. METHODS: Using Hospital Episode Statistics, cases that were readmitted within 30days of primary operation were identified retrospectively. Demographics including age, gender, preexisting comorbidities, diagnosis on primary admission and the treatment, length of stay, and diagnosis on readmission with treatment, including further surgical intervention, were collected from discharge summaries and hospital notes. Neonates were excluded from this study. Comorbidities, involving one or more systems, were also identified for each case of readmission. ReAds were classified into emergency and elective cohort depending on the nature of the primary operation. Outcomes were compared between these two groups. Data were quoted as median (range) unless indicated otherwise. Data were analyzed using SPSS software Desktop 22.0, using Mann-Whitney U and Chi-Squared tests, with a consideration that a P≤0.05 was significant. RESULTS: A total of 2378 procedures were performed during the study period. Elective cases, including day cases, accounted for 77% (n=1837) of all cases. The remaining 23% (n=541) were emergency cases. Total unplanned readmission rate within 30days (ReAd) was 2%. Further surgical procedures were required in 38%. Having excluded neonates, the most common primary procedure leading to readmission within 30days was appendicectomy (26%). Overall, the most common cause for readmission within 30days was postoperative infection (30%). The ReAd in emergency cohort was 3.5% in comparison to 1.5% in elective, which was significantly different (P value=0.007). CONCLUSION: Readmission within thirty days of primary procedure in pediatric surgery has little published data. An efficient discharge planning may play a vital role in preventing unwanted readmission. Elective operations had a significantly lower readmission rate than emergency operations. Having excluded neonates, appendicectomy was found to be the most common operation associated with readmission in the pediatric surgical practice. Although widely used as quality care indicator in adults, more studies are required to validate readmission rate as a quality of care indicator in pediatric surgery practice.

Thyroid Surgery in Children: Clinical Outcomes.

AIM: The aim of this study was to review the outcomes of thyroid surgery in children operated for both benign and malignant conditions. PATIENTS AND METHOD: Demography, clinical features, and surgical outcomes were noted retrospectively for operations performed during the last 23 years. Results were analyzed using Fisher exact test and Woolf (logit) method with p value < 0.05 considered as significant. RESULTS: In total, 61 children (43 girls and 18 boys) underwent thyroidectomy for benign (70%) and malignant (30%) conditions. Median follow-up period was 1.4 years. In the benign group, 84% children had Graves disease and 16% had other conditions. In this study, 42% children had total, 22% had near-total, 27% had subtotal, and 9% had type 2 hemithyroidectomy. In the malignant group, 50% had multiple endocrine neoplasia, 33% had papillary, 11% had follicular cancer, and 6% had B-cell lymphoma. Fifty percent children had prophylactic thyroidectomy, 44% had total thyroidectomy plus lymphadenectomy, and 6% had hemithyroidectomy. At the time of surgery, children with benign conditions were older than those with malignancy (median, 12 vs. 7.5 years). There were no incidents of postoperative bleeding or infection. Hypocalcemia was significantly more frequent in the malignant group (39 vs. 9%, p value = 0.01). The type of recurrent laryngeal nerve (RLN) injury was more serious in the benign group (one bilateral and one unilateral permanent injury) than in the malignant group (transient hoarseness in three). Overall rate of complications was higher for operations for malignancy (56 vs. 28%, p value = 0.07). In Graves disease, the subtotal thyroidectomies had a recurrence of 30% but no recurrence was seen following total or near-total thyroidectomy group (p value = 0.01). There was no recurrence in the malignant group. Children operated after 2000 were younger than those operated before 2000 (median age, 9 vs. 14 years). Malignant conditions were more common in children operated after 2000 in comparison to before 2000 (55 vs. 10%). CONCLUSION: Benign conditions are commonest indications for thyroid surgery in children but the incidence of surgery for malignant conditions is rising. Overall rate of complications, especially hypocalcemia, is higher after surgery for malignancy but all cases of permanent RLN injury were in benign group. Total or near total thyroidectomy prevents recurrence of thyrotoxicosis and is an operation of choice for Graves disease.

Closing left gastroschisis with vanishing left testis.

We report a baby boy with gastroschisis with left non-palpable undescended testis who had a defect on the left side of an intact and normal umbilical cord and had associated testicular atrophy and abnormalities of the ductus deferens. They were successfully managed by primary repair and had uneventful recovery. Subsequent inguinal exploration confirmed blind ending vas deferens and vanishing left undescended testis. Our case confirms vascular accidents at the narrow abdominal wall defect can lead to vanishing testis following attempts at closing gastroschisis making the defect narrow and compromising the blood supply to the testis.

Inferior gastroschisis.

Gastroschisis is a common defect of the central abdominal wall, nearly always located to the right of the umbilicus. We report a baby boy with gastroschisis who had a defect on the inferior side of an intact and normal umbilical cord which was managed by primary repair and an uneventful recovery. Such a case has never been reported in the literature. This case contributes towards enlarging the spectrum of gastroschisis.

Neonatal prolapsed patent vitellointestinal duct.

A case of a prolapsed patent vitellointestinal duct (PVID) in a 10-day-old neonate who presented with vomiting and poor weight gain with partial intestinal obstruction and a flower like pink, prolapsing lesion at his umbilicus has been reported. A limited contrast study through the tubular structure confirmed it to be a PVID. He underwent transumbilical exploration and resection and anastomosis uneventfully. Persistence of the vitellointestinal duct as a whole or part of it leads to a wide variety of anomalies-Meckel's diverticulum is the commonest lesion and a PVID is the rarest. Umbilical cord clamping flush with the abdominal wall may convert a Meckel's diverticulum prolapsing in the base of umbilical ring into a PVID. Careful assessment should be made for associated anomalies. Transumbilical exploration gives the best cosmetic and functional results.

Massive lower gastrointestinal haemorrhage in a teenager caused by Campylobacter enteritis.

A 14-year-old boy presented with a very unusual complication of massive lower gastrointestinal bleeding mimicking bleeding from Meckel's diverticulum who needed blood transfusions and required mini-exploration. He was found to have Campylobacter enteritis with bleeding from multiple mucosal ulcers in the ileocaecal region, which is presented with a review of the literature.

Thoracoscopic sympathectomy for palmar hyperhidrosis in children: 21 years of experience at a tertiary care center.

PURPOSE: The aim of this study was to find out the outcome of "thoracoscopic sympathectomy" (TS) for palmar hyperhidrosis (PH) in children. To our knowledge, this is the largest experience of TS from the United Kingdom. METHOD: All patients who underwent TS for PH during the past 21 years were studied retrospectively. RESULTS: A total of 85 procedures were done in 44 children. Ratio of female to male was 4:1. Median age at operation was 12.8 years. Types of operations performed were as follows: bilateral T2-T3 sympathectomy in 87% (38/44), bilateral T2-T5 sympathectomy in 9% (4/44), and right-sided thoracoscopic (left-sided done open) in 1% (0.5/44); operation was not possible in 3% (1.5/44) of cases. No chest drains were used. Median postoperative stay was 2 days (range 1 to 5). Median follow-up time was 1.3 years (range 0.2 to 4.7 years). Only problematic patients were followed up for longer. During follow-up, 21% (9/44) developed severe hyperhidrosis of other parts of body. Seven percent (3/44) of patients developed severe axillary hyperhidrosis (AH) and required T4-T5 sympathectomy later on at a median age of 14.4 years (range 11 to 16 years). Another 9% (4/44) patients developed severe plantar hyperhidrosis. Severe hyperhidrosis of the whole body was seen in 5% (2/44) of the patients. Postoperative complications were seen in 47% (21/44) of the patients. They were as follows: postoperative pain (needing > 48 hours hospital stay) in 18% (8/44); transient Horner syndrome in 18% (8/44-right 5, left 3); and recurrence of PH in 11% (5/44) of cases. In the recurrence group, 7% (3/44) were unilateral (right 2, left 1) and 5% (2/44) were bilateral. Redo operations were performed in 11% (5/44) of cases. Median time to redo was 2.6 years (range 8 months to 4.2 years). All three unilateral recurrent patients underwent respective sided redo. In the bilateral recurrence group (2/44), one patient had bilateral redo (remained dry), whereas the other patient underwent only right-sided operation (remained dry), as that sided operation was difficult and so the other side was not tried. FINAL OUTCOMES: The final outcomes were recurrence 3.5% (3/85-right 2, left 1) and technically failed operation 3.5% (3/85-both sides 1, one side 1). Success rate for thoracoscopic sympathetectomy was 93% (79/85) overall. CONCLUSION: TS for PH is a safe and feasible operation in children. It is successful in the majority; however, the procedure is not trouble free.
