Can paediatric surgical registrars safely perform supervised hypospadias surgery?

INTRODUCTION: Hypospadias repair is regarded as a technically demanding, complex procedure, with variable outcomes. Therefore, it tends to be performed by consultants, with limited trainee involvement. We aimed to study the clinical outcomes of supervised registrars performing proximal and distal hypospadias repairs, compared to their consultant mentors. METHODS: We undertook a retrospective review of all primary hypospadias repairs performed between April 2013-April 2022 at our tertiary paediatric urology centre. Redo repairs and patients lost to follow-up were excluded. Pre-operative anatomy, theatre time, grade of primary surgeon (registrar (trainees and non-training middle grades) or consultant), operative technique, follow-up duration, complications, and reoperation rates were recorded. The procedures were assessed in two groups according to the primary operator: registrar or consultant. The Zwisch scale is used to describe level of consultant support. Registrars as primary operators received "passive help" or "supervision" (Zwisch levels 3/4). Consultants as primary operators provided registrars with "show-and-tell" or "active help" (Zwisch levels 1/2). RESULTS: 270 procedures performed on 228 patients met the inclusion criteria. 109 were performed by registrars and 161 by consultants. In both groups, median age was two years (p = 0.23). Median theatre time was similar (registrars 2.8 h vs. consultants 2.7 h, p = 0.88), as was median follow-up (registrars 25months, vs. consultants 21months, p = 0.99). Operations performed by registrars were 76% distal and 24% proximal; and by consultants were 62% distal and 38% proximal. The overall urethroplasty complication rate was similar, at 24% for registrars and 23% for consultants (p = 0.89). The summary table shows the distribution of different complications. Re-operation rate was 16% in both groups (p = 0.99). Complications were further assessed according to operation type (TIP vs. two-stage repair). DISCUSSION: Contrary to popular belief amongst hypospadiologists, we found complication rates were similar for registrar and consultant surgeons. We question that involvement of registrars increases complications. The literature demonstrates safety of trainee performance of limited steps of the procedure. However our institution permits registrars to perform up to the whole hypospadias repair under direct supervision, with no predefined limit to their involvement. CONCLUSION: Paediatric surgical registrars can be safely supervised to have substantial involvement in proximal and distal hypospadias repair, without compromising the duration or outcomes of surgery. We hope that allowing more registrar involvement can lead to faster acquisition of surgical skills, whilst remaining under the safety of senior supervision. Increasing opportunities for those with an aptitude for hypospadias repair can equip them with skills and confidence for entering fellowship training.

Correction of curvature in single stage hypospadias repair with foreskin reconstruction.

INTRODUCTION: Many surgeons offer foreskin reconstruction (FR) as a routine part of hypospadias repair. We present a step-by-step video of the procedure of Tubularised Incised Plate (TIP) repair, FR and dorsal plication through a ventral skin incision. MATERIALS AND METHODS: A ventral incision is made between the inner preputial mucosa and the outer skin extending below the meatus. Ventral degloving is carried out. The dissection is extended laterally around the corporal bodies. The point of maximal curvature (PMC) is marked on the dorsal midline. A vertical incision is made and closed transversely with 5-0 prolene suture in a Heineke- Mikulicz fashion. Urethroplasty is performed in 2 layers using 7-0 polydioxanone (PDS). Spongioplasty and ventral dartos are used as barrier layers. Glansplasty is performed in 2 layers.FR is carried out in 3 layers. DISCUSSION: Curvature correction is key to good outcome. Dorsal degloving can be achieved through a ventral incision allowing exposure of the dorsal midline for plication sutures. RESULTS: The patient had good cosmetic and functional outcome at 1 month follow up. CONCLUSION: FR can be safely performed during TIP repair for distal hypospadias repair. Curvature of less than 30° can be corrected through a ventral incision only.

Bladder bowel dysfunction in children with Down's syndrome.

INTRODUCTION: Bladder Bowel Dysfunction (BBD) has been described in patients with Down's Syndrome (DS). Our aim was to report the incidence, demographics, presentation, complications and management of the bladder in DS patients with BBD. METHODS: A systematic review was performed using PRISMA guidelines and search terms "{[(trisomy 21) OR down's syndrome]} AND [("non-neurogenic") OR voiding dysfunction]" in the search engines MEDLINE and SCOPUS. We also include a case series from two paediatric urology centres. RESULTS: A total of 38 patients with BBD and DS were included. Mean age was 12 years (newborn to 21 years), the male:female ratio was 2:1. Functional constipation (90%), recurrent urinary tract infections (38%) and enuresis were common at presentation (56%), while over 56% patients required surgical intervention. Medical treatment and behavioral modification were less successful while intermittent catheterisation did not work. CONCLUSION: This study reviews the largest cohort of patients with BBD in DS. It is common with serious consequences requiring operative intervention. Usual interventions are unreliable due to poor compliance. Early identification and management protect the renal tract. Regular screening for urogenital anomalies in DS is currently not performed. We recommend a thorough history of bladder function in DS patients to identify these cases early.

Educational survey of regional general practitioner's management of paediatric patients with undescended testis.

INTRODUCTION: Recent recommendations have lowered the ideal age of surgery for undescended testis (UDT) to 3-6 months of age. However, many publications demonstrate that age at surgery is still above the recommended age of 1 year as originally suggested in 1996. AIM: Through a web-based educational survey, we aimed to combine questions regarding General Practioner's (GPs) management of these patients with educational slides with advice to update them with current recommendations. METHODS: The regional GPs were invited by email and letter to undertake the web-based questionnaire devised using SurveyMonkey(®). Educational slides were shown after each questionnaire slide. Feedback was immediate and a one-page summary was emailed to the GP on completion. A pre- and post-educational intervention audit was undertaken to ascertain the change in age of referral for patients <5 years of age. RESULTS: 144 (36%) of 401 GPs undertook this survey. 84% were happy assessing infants (<1year) with UDT. 16% were unhappy discussing management with parents for palpable UDT. 52% were happy discussing malignant risk with parents. 80% thought that ultrasonography was routinely used. Optimal referral time was thought to be 6-12 months (42%) and time of surgery was 1-2 years (50%). 72% would refer a patient with palpable UDT after 6 months of age. Only 41% were happy to assess testicular size at puberty. 98% found this format of an educational survey was helpful. The average age of referral for patients <5 years improved significantly after educational intervention from 2.8 years in 2010 to 1.25 years in 2013 (p < 0.01). DISCUSSION: With an interactive survey, we were able assess and also educate the regional GPs with regard to management of paediatric patients with UDT. There is a varied range of knowledge and practice demonstrated which we hoped to standardise and thereby increase efficiency and decrease the age of referral. A large majority would refer patients with UDT after 6 months of age that would make the target of surgery <6 months unachievable unless they are aware of current recommendations. This study is limited by a 36% response rate but that is comparable to other surveys. Also, referrals come from other sources that were not included. The causal effect of the educational survey is hypothesised. CONCLUSION: This educational survey has confirmed the varied management by GPs. The referral age was demonstrated to be reduced after this intervention and this process was widely accepted by GPs that undertook the educational survey.

Video presentation of the second stage of a two-stage repair for proximal hypospadias: a safe and reproducible technique.

OBJECTIVE: The aims of proximal hypospadias repair are good cosmetic outcomes with low rates of complication, with a low number of operative exposures, before the age of genital difference realisation. Neo-urethral fistula and stenosis are well recognised complications; with international rates of 3.8-16% and 1.3-15.6% respectively. We present the key steps of the second of a two staged repair in video format. METHOD: Video recording of the procedure performed on an 18-month-old with mid-penile hypospadias is presented. The steps are described; the importance of tension free tubularisation, layered urethral closure, suture technique, vascularised prepucal graft technique, optimal glanuloplasty, and penile shaft skin repair are highlighted. RESULT: The child was brought back to the day ward for catheter removal at 7 days; follow-up in clinic showed good postoperative appearance. This technique has been performed on 31 boys with a fistula rate and stenosis rate favourable to the literature. CONCLUSION: We demonstrate a two-stage technique by video format for proximal hypospadias which is reproducible and gives results comparable to the literature.

Incarcerated inguinal hernia management in children: 'a comparison of the open and laparoscopic approach'.

PURPOSE: To compare the outcomes of management of incarcerated inguinal hernia by open versus laparoscopic approach. METHODS: This is a retrospective analysis of incarcerated inguinal hernina in a paediatric surgery centre involving four consultants. Manual reduction was attempted in all and failure was managed by emergency surgery. RESULTS: The laparoscopy group had 27 patients. Four patients failed manual reduction and underwent emergency laparoscopic surgery. Three of them had small bowel strangulation which was reduced laparoscopically. The strangulated bowel was dusky in colour initially but changed to normal colour subsequently under vision. The fourth patient required appendectomy for strangulated appendix. One patient had concomitant repair of umbilical hernia and one patient had laparoscopic pyloromyotomy at the same time. One patient had testicular atrophy, one had hydrocoele and one had recurrence of hernia on the asymptomatic side. The open surgery group had 45 patients. Eleven patients had failed manual reduction requiring emergency surgery, of these two required resection and anastomosis of small intestine. One patient in this group had concomitant repair of undescended testis. There was no recurrence in this group, one had testicular atrophy and seven had metachronous hernia. CONCLUSIONS: Both open herniotomy and laparoscopic repair offer safe surgery with comparable outcomes for incarcerated inguinal hernia in children. Laparoscopic approach and hernioscopy at the time of open approach appear to show the advantage of repairing the contralateral patent processus vaginalis at the same time and avoiding metachronous inguinal hernia.

Current practice in feminizing surgery for congenital adrenal hyperplasia; a specialist survey.

AIM: To present the outcome of an online survey of the current practice in feminizing surgery for congenital adrenal hyperplasia (CAH) among the specialists attending the IVth World Congress of the International Society of Hypospadias and Disorders of the Sex Development (ISHID), 2011. MATERIAL AND METHODS: An online survey covered 13 individual questions regarding the management and surgical techniques for 46XX CAH patients. All delegates attending the conference were invited to complete this anonymous survey. The data was analysed by three of the authors. RESULTS: A total of 162 delegates had registered for the conference and 60% of them were paediatric surgeons or paediatric urologists. 65 delegates completed the online survey. Early surgery, before the age of two years, is preferred by 78% of the surgeons and most of them would include clitoroplasty, vaginoplasty and labioplasty. The most frequent surgical technique used for the clitoroplasty is the partial excision of the corpora cavernosa and the skin flap or "U flap" vaginoplasty. Routine vaginal dilatations after puberty are advocated by 28% of the delegates. More than 75% report good outcomes. CONCLUSIONS: Within the limitations of the methodology of this survey, this study suggests that there is agreement in many aspects related with the surgical treatment for 46XX CAH. Self reported outcomes are satisfactory for most of the respondents.

Current practice in paediatric hypospadias surgery; a specialist survey.

AIM: To undertake an online survey of current hypospadias surgery practice among those specialists attending the IVth World Congress of the International Society for Hypospadias and Disorders of Sex Development (ISHID), 2011. MATERIALS AND METHODS: An online survey covering 22 separate questions relating to proximal and distal hypospadias surgery was set up, and all delegates registered for the conference were invited to complete this questionnaire anonymously. The data was analysed by three of the authors. RESULTS: A total of 162 delegates registered for the conference of whom 74% were paediatric surgeons, paediatric urologists, plastic surgeons and adult/adolescent urologists. 93 delegates completed the online survey, and most of them (57%) were from Europe. The majority of surgeons see over 20 new patients/year (90%) and perform primary hypospadias surgery in over 20 patients/year (76%). The tubularized incised plate (TIP) repair is the most frequent technique used for the management of distal hypospadias (59%); other techniques used included Mathieu, onlay and TIP with graft. A variety of techniques are used for proximal hypospadias, but nearly half of the respondents (49%) preferred a staged approach. Self reported complication rates for distal hypospadias surgery are favourable (less than 10%) for 78% of the respondents. However, proximal hypospadias complication rates are higher. CONCLUSIONS: With a majority of paediatric urologists and European delegates responding to our survey, the results suggest that there are differences in the management of proximal and distal hypospadias between surgeons, yet no differences were observed according to the region of their practice. Variations in long-term outcomes appear to be in keeping with the current literature.

Varicocele surgery: 10 years of experience in two pediatric surgical centers.

AIM: The study was designed to compare recurrence rates and complications after laparoscopic versus open varicocele surgery in children. SUBJECTS AND METHODS: A retrospective case-note review of all varicocele surgery over a 10-year period (April 1999-March 2009) in two pediatric surgical centers was performed. Multivariate analysis using logistic regression was performed using SPSS Statistics version 18 (SPSS Inc., Chicago, IL). RESULTS: Thirty-seven patients had varicocele surgery during the study period. The median age at surgery was 14 years (range, 11-16 years). Most children had left-sided Grade 2 varicocele. Twenty-five (68%) primary procedures were laparoscopic (17 artery-sparing), and 12 (32%) procedures were open (9 artery-sparing). Six (16%) children had recurrence, and 6 (16%) had postoperative hydrocele. Recurrence rates after laparoscopic (16%) and open (17%) surgery were similar. Increasing age significantly decreased recurrence (odds ratio, 0.373; 95% confidence interval 0.161-0.862; P = .021). Although laparoscopy was associated with higher rates of postoperative hydrocele (odds ratio, 2.817; 95% confidence interval, 0.035-3.595; P = .380) and artery-sparing ligation was associated with higher rates of recurrence (odds ratio, 2.667; 95% confidence interval, 0.022-4.235; P = .787), these associations were not statistically significant. CONCLUSIONS: The best results of varicocele surgery in terms of recurrence and postoperative hydrocele were achieved by open mass ligation; however, larger prospective studies are warranted.

Bracka's staged repair of proximal hypospadias--revisiting a versatile technique.

OBJECTIVE: Proximal hypospadias is associated with poorly defined urethral plate and often with chordee. A two-staged Bracka's repair is reproducible and has been used routinely in our practice. We present the key steps of this technique on a 13-month-old boy. PATIENT AND METHOD: This boy presented with proximal penile hypospadias, hooded foreskin and mild chordee. He underwent stage one Bracka's repair. The steps included: 1) Artificial erection test to define extent of chordee; 2) inner preputial graft harvest and preparation; 3) glans and urethral plate incision down to corpora cavernosa; 4) partial release of chordee by division of aberrant corpus spongiosum, without degloving of penile skin; 5) laying of preputial graft; 6) dressing. RESULT: The patient had catheter removed on second, and dressing removed on seventh, post-operative days, without complication. The patient is planned for second stage repair in 6 months. Our standard approach includes either removal of catheter on the second or seventh post-operative day, according to surgeon preference. The three senior surgeons have used this method in 54 patients without significant complication. The graft has taken in 100% of cases. CONCLUSION: The Bracka's staged repair of proximal hypospadias is a versatile technique that gives reproducible and sound results.

Pediatric advanced appendicitis: open versus laparoscopic approach.

PURPOSE: Optimal surgical approach for advanced pediatric appendicectomy remains controversial. We compare the open versus the laparoscopic approach. METHODS: Retrospective case notes review of children operated on for advanced appendicitis between January 2005 and July 2006 was undertaken for length of hospital stay, operating time, wound complications, need for further surgery, and hospital readmission. RESULTS: Forty children were included, 17 were treated with open approach and 23 with laparoscopic approach. There was no conversion from laparoscopic to open approach. Overall complication rate, length of hospital stay, and need for further surgery were similar in both groups. The mean operative time was longer in the laparoscopic group. Wound complications occurred more in the open group. Readmission for gastrointestinal obstruction was noted in the laparoscopic group. CONCLUSIONS: Laparoscopic approach is safe for advanced appendicitis in children. The outcomes are comparable in both study groups.

Meconium per vagina: a rare presentation of meconium peritonitis.

Meconium peritonitis results from antenatal perforation of the gastrointestinal tract; it presents as gastrointestinal obstruction, intraabdominal masses, or calcification. The presentation with passage of meconium per vagina secondary to meconium peritonitis is rare. We describe the radiologic and surgical findings in a neonate who had passage of meconium per vagina secondary to ileal atresia and meconium peritonitis. Initial clinical and radiologic examination suggested rectal atresia with an associated rectovaginal fistula, although subsequently, this was not the case. Possible explanations for the passage of meconium per vagina include decompression of a meconium cyst via the left fallopian tube or direct perforation of a collection into the vagina from the peritoneal cavity.

Home next day: early discharge of children following appendicectomy.

Fifty-six children in two groups were discharged within 24 hours of an uncomplicated appendicectomy. While the children in the first group (N = 21) were visited by a nurse at home within 24 hours of discharge, the second group (N = 35) just received telephone calls. The cohort was evaluated by telephone interviews two weeks after discharge. All children fulfilling the discharge standards were discharged safely within 24 hours of surgery. Any physical complaints post-discharge were considered minor. The nurses were able to provide reassurance to the families, give advice and deal with minor problems. As a result the families felt safe and reassured, and in only one case did the fragility of parental confidence become obvious. This study has demonstrated the safety of discharging these children within 24 hours of surgery and the value to nursing contacts in enabling the families to care for their children at home.

Early discharge following uncomplicated appendicectomy in children.

This cohort evaluation investigated the discharge of 15 children within 12 to 24 hours following an uncomplicated appendicectomy who were subsequently supported by an outreach nurse. By monitoring the child's progress, providing the support the family was expected to require and offering professional back-up for any unforeseen problems the outreach nurse ensured the child's safety and improved quality of care after early discharge from the hospital. The pivotal importance of the outreach nursing input was demonstrated when the expected visit did not materialise for one child.
