RESUMEN
PURPOSE: Factors leading to mechanical complications following insertion of central venous access devices (CVADs) in children are poorly understood. We aimed to quantify the rates and elucidate the mechanisms of these complications. METHODS: Retrospective (2016-2021) review of children (< 18 years old) receiving a CVAD. Data, reported as number of cases (%) and median (IQR), were analysed by Fisher's exact test, chi-squared test and logistic regression analysis. RESULTS: In total, 317 CVADs (245 children) were inserted. Median age was 5.0 (8.9) years, with 116 (47%) females. There were 226 (71%) implantable port devices and 91 (29%) Hickman lines. Overall, 54 (17%) lines had a mechanical complication after 0.4 (0.83) years from insertion: fracture 19 (6%), CVAD migration 14 (4.4%), occlusion 14 (4.4%), port displacement 6 (1.9%), and skin tethering to port device 1 (0.3%). Younger age and lower weight were associated with higher risk of complications (p < 0.0001). Hickman lines had a higher incidence of complications compared to implantable port devices [24/91 (26.3%) vs 30/226 (13.3%); p = 0.008]. CONCLUSION: Mechanical complications occur in 17% of CVADs at a median of < 6 months after insertion. Risk factors include younger age and lower weight. Implantable port devices have a lower complications rate. LEVEL OF EVIDENCE: Level 4: case-series with no comparison group.

PURPOSE: To define the practice of management for Hirschsprung disease (HD) in Australia and New Zealand. METHODS: Online survey of Australian and New Zealand Association of Paediatric Surgeons (ANZAPS) members. RESULTS: 56/80 (70%) members from 17 centres responded. DIAGNOSIS: 100% perform suction rectal biopsies; 40% perform a contrast enema. HISTOPATHOLOGICAL STAINING: H&E (94%), ACHE (70%) and calretinin (75%). SURGERY: Primary pull-through (PT) is performed by 88% (100% by < 6/12 months). The Soave-Boley PT is the preferred approach (85%), with laparoscopic assistance (77%) and muscle cuff division (93%). Routine post-operative dilatations are performed by 63% of respondents. If symptoms persist following PT, majority adopt a conservative approach (enemas/laxatives 90%; Botox 74%). If a long-segment is identified at PT, 60% fashion a stoma and delay definitive surgery. If total colonic aganglionosis is identified at PT, 76% fashion a stoma and delay definitive surgery. A dedicated bowel management program is available in 45% of centres with transition to adult services in 29%. CONCLUSIONS: A laparoscopic-assisted Soave-Boley PT is the most common technique for recto-sigmoid HD. Differences are noted in both the management of long-segment/total aganglionosis HD and post-operative management/follow-up.

PURPOSE: To quantify the rates and identify risk factors for the complications of central venous access devices (CVADs) removal in children. METHOD: Retrospective (2018-2023) review of children undergoing CVADs removal at a single institution. Data are reported as frequency, percentages and median. Logistic regression analysis was used to identify risk factors associated with difficult removal. Receiver Operating Characteristic Curve (ROC) analysis was conducted to identify the age cut-off and positive likelihood ratio (+LH) for the indwelling time associated with complicated removal. p-Value <0.05 were considered statistically significant. RESULTS: We identified 208 CVAD removals with a median age of 7.2 (0.2-18.4) years including 116 (55.8%) males. The median CVAD placement duration was 1.26 years (0.4-5.7) years. Indications for insertion included acute lymphoblastic leukaemia (ALL; 78/208, 37.5%), lymphomas (31/208, 14.9%), other malignancies (58/208, 27.9%). Removal indications included completion of treatment (144/208, 69.2%), infection (22/208, 10.6%), malfunction (7/208, 3.4%) and other reasons (35/208, 16.8%). There were 20 (9.6%) complications characterised by difficulty removing the CVAD. Complicated removals were more likely to occur in children with ALL as the primary diagnosis (p = 0.001); independently of the indication for insertion, longer indwelling time was associated with higher risk of complicated removal (p < 0.001). Indwelling time >2.09 years was associated with a 2.87 increased risk of difficult removal. CONCLUSION: In our experience, almost 10% of CVAD removals in children result in complications. These findings are associated with an indwelling time >2 years; strategies to prevent complicated removals should be considered in children requiring long-term central venous access.
RESUMEN
BACKGROUND: The optimal management of perianal abscess in neonates and infants remains unclear, including the need for laying open of the fistula and the role of microscopy and culture studies (MCS). We aimed to report the recurrence rate following incision and drainage alone (I&D) compared to incision and drainage with laying open of the fistula (I&DF) and to determine the value of MCS in perianal abscess management. METHODS: Following ethical approval (16326Q), a 10-year (2007-2017) review of children younger than 1 year presenting with a perianal abscess was performed. Presence of a fistula was sought in all patients. Data are presented as number of cases (%), median (range) and analysed using Fisher's exact test and Mann-Whitney U-test. P-values of <0.05 were considered significant. RESULTS: We identified 108 patients (107 (99.1%) males) with 111 abscesses (three bilateral); 26 in I&D group and 85 in I&DF group. Initial abscess occurred to the right of midline in 64 cases (58%) and to the left of midline in 47 cases (42%). Twenty-two (20%) recurred after 30 (6-372) days. Sixty-five (59%) had MCS performed. Recurrence was higher in I&D group (9/26) versus I&DF group (13/85) (P = 0.04 (relative risk 2.2, 95% confidence interval 1.0-4.5)). There was no difference in recurrence within each group between patients with or without MCS (I&D group, P = 0.1; I&DF group, P = 0.3). CONCLUSION: The recurrence of surgically managed perianal abscess is lower when a fistula is identified and laid open at the initial operation. There is little value of MCS in the management of paediatric perianal abscess.

AIMS: To review the demographics, presenting features, rates of air enema reduction success, prevalence of pathological lead points and surgical intervention rates and outcomes in patients with intussusception at Starship Children's Hospital (Auckland, New Zealand). To use this data to guide management of children at a national level in New Zealand. METHOD: Retrospective case series. Patients discharged from Starship Children's Hospital between 1 January 1998 and 31 December 2007 with a diagnosis of intussusception were obtained from coding data. RESULTS: 189 patients were analysed. 30% presented with the classic triad of pain, rectal bleeding and mass. 150/189 proceeded to air enema reduction which was successful in 118 (78.7%) of cases with 2 perforations. 54/189 (28.6%) proceeded for operative reduction of which 26 patients required surgical resection. Clinical and radiological evidence of bowel obstruction and duration of symptoms were associated with failed enema and surgical resection. CONCLUSION: Intussusception only occasionally presents with the typical triad of abdominal pain, rectal bleeding and abdominal mass. Air enema reduction is successful at this institution with a low level of complication. Maori and Pacific patients had higher rates of failed enema reduction and need for surgery compared to European patients. Further research is needed from peripheral centres to evaluate outcomes of children treated in district hospitals to identify how and where these children are best managed.

PURPOSE: To look at the presentation and management of labial hypertrophy in 2 young adolescents. TYPE OF STUDY: Case report MAIN FINDINGS: We present two cases, a 10-year-old girl with concerns regarding a hypertrophied labia minora and a 12-year-old girl with spina bifida and difficulty in performing intermittent catheterization because of the hypertrophied labia. We discuss a simple technique for reduction labioplasty and the different surgical options. CONCLUSION: Hypertrophy of one or both labia minora can lead to functional, social, esthetic and sexual problems in females of all ages. As the age of sexual awareness and activity gets younger we can expect more presentations of this problem in the pediatric population. Many girls with spina bifida may also present with problems due to the hypertrophied labia. As pediatric surgeons are called upon to deal with adolescent gynecology we need to be competent in managing this condition.
