Abstract
PURPOSE In our center, patients with anorectal malformation, including males with recto-vesical (RV)/recto-bladder neck (RBN)/recto-prostatic urethral (RU) fistulas, and females with recto-vaginal (RV) fistulas have been treated by posterior sagittal anorectoplasty (PSARP) before 2000, and by laparoscopic-assisted anorectal pull-through (LAARP) thereafter. We would like to compare the quality of life (QOL) and long-term defecative function between these two groups of patients 10 years after reconstructive surgery. METHODS Patients who underwent LAARP between 2001 and 2005 were compared with historical controls treated with PSARP between 1996 and 2000. Degrees of continence were graded by the Krickenbeck classification and Kelly's score. QOL was assessed by Hirschsprung's disease/Anorectal Malformation Quality of Life (HAQL) questionnaire. Results were compared using Chi-square test and t test. RESULTS There were 14 LAARP and 7 PSARP patients. All attained voluntary bowel movements. Moderate to severe soiling (Krickenbeck Grade 2 and 3) was found in 3/14 LAARP (21.4%) and 1/7 PSARP (14.3%) patients, p = 1.00. Constipation requiring use of laxatives was present in 3/14 LAARP (28.6%) and 1/7 PSARP (14.3%) patients, p = 0.62. Mean Kelly's scores were 3.79 ± 0.98 (LAARP) and 4.71 ± 1.25 (PSARP), p = 0.12. No patient required Malone antegrade continence enema (MACE). The QOL scores based on the HAQL questionnaire were comparable between the two groups in all areas except social functioning, in which the LAARP patients attained a significantly lower mean score (26.4 vs 71.7, p = 0.0001). CONCLUSION The 10-year outcome between LAARP and PSARP patients in terms of QOL and defecative function is comparable. Impairment in social functioning in these patients is reflected by the self-reported lower level of functioning.

Abstract
BACKGROUND Intussusception may require bowel resection. Here, we aim to define factors that predict the need of bowel resection and the presence of pathological lead point. METHODS A retrospective review was taken from three tertiary centers for all operated intussusception patients from January 2010 to December 2014. Patient demographics were recorded. Statistical analysis was performed, and risk factors were derived by binary logistic regression. RESULTS Five thousand ninety-six patients were treated for intussusception with 73 (57 male, 16 female) operated. The median age was 23.2months, and median duration of symptoms was 2days. Twenty-eight patients (38.4%) required bowel resection. Logistic regression demonstrated that older age (p=0.018) and longer duration of symptoms (p=0.009) were associated with bowel resection. Furthermore, older age was a predictive factor for the presence of a pathological lead point (p=0.01). A palpable abdominal mass was also found to be associated with the need of bowel resection (risk ratio 2.3) and the presence of pathological lead point (risk ratio 2.3) independently. CONCLUSION Older age at presentation and a longer duration of symptoms are positive predictors for the need of bowel resection in intussusception. The presence of a pathological lead point is more likely in older children. LEVEL OF EVIDENCE Case series with no comparison group - Level IV.

Abstract
BACKGROUND Perforated peptic ulcer (PPU) is a relatively uncommon condition in children. We aim to evaluate and compare the outcomes of laparoscopic omental patch repair versus open repair for PPU in pediatric patients. METHODS Children who underwent omental patch repair for PPU from 2004 to 2014 in our hospital were reviewed retrospectively. Patient demographics, perioperative as well as intraoperative details and surgical outcomes, were analyzed. RESULTS Thirteen patients were identified, and all presented with abdominal pain. The median age of the study group was 14.9years (range 6.3 to 18.4years). Radiological evidence of pneumoperitoneum on erect chest x-ray (CXR) was found only in five patients (38.5%). None of the patients had a known history of peptic ulcer disease. Diagnosis other than PPU was made in five patients preoperatively. Laparoscopic repair was attempted in eight patients with one of them requiring conversion. There was no significant difference in patient demographics when compared with the open repair group. The perforation site was in the duodenum in 11 patients and in the antrum in two patients. The mean size of perforation was larger in the open repair group (p=0.005). Although the operating time was longer in the laparoscopic group (p=0.51), the length of hospital stay was significantly shorter (p=0.048). Only two patient diseases were Helicobacter pylori related. CONCLUSION Clinical features of perforated peptic ulcer in children are different from adults. Risk factors are less frequently identified. Laparoscopic omental patch repair is a feasible surgical option and is associated with satisfactory outcomes in pediatric practice.

Abstract
Chemotherapy of paediatric haematological malignancies can induce infectious complications of the gastrointestinal tract, with predilection of the ileocaecal region. Common causes of right lower abdominal pain in the febrile patient with neutropaenia include acute appendicitis, typhlitis, ileus and intussusception. In this case report, we describe a teenage boy with acute appendicitis presenting with pneumoperitoneum during his course of chemotherapy. The incidence, aetiology, diagnosis, investigations and management of this uncommon presentation in a common disease are discussed. The controversial topic of the management of acute appendicitis in a febrile patient with neutropaenia is also reviewed and discussed.

Abstract
OBJECTIVES To review all paediatric patients with intussusception over the last 17 years. DESIGN Retrospective case series. SETTING A tertiary centre in Hong Kong. PATIENTS Children who presented with intussusception from January 1997 to December 2014 were reviewed. MAIN OUTCOME MEASURES The duration of symptoms, successful treatment modalities, complication rate, and length of hospital stay were studied. RESULTS A total of 173 children (108 male, 65 female) presented to our hospital with intussusception during the study period. Their median age at presentation was 12.5 months (range, 2 months to 16 years) and the mean duration of symptoms was 2.3 (standard deviation, 1.8) days. Vomiting was the most common symptom (76.3%) followed by abdominal pain (46.2%), per rectal bleeding or red currant jelly stool (40.5%), and a palpable abdominal mass (39.3%). Overall, 160 patients proceeded to pneumatic or hydrostatic reduction, among whom 127 (79.4%) were successful. Three (1.9%) patients had bowel perforation during the procedure. Early recurrence of intussusception occurred in four (3.1%) patients with non-operative reduction. No recurrence was reported in the operative group. The presence of a palpable abdominal mass was a risk factor for operative treatment (relative risk=2.0; 95% confidence interval, 1.8-2.2). Analysis of our results suggested that duration of symptoms did not affect the success rate of non-operative reduction. CONCLUSIONS Non-operative reduction has a high success rate and low complication rate, but the presence of a palpable abdominal mass is a risk factor for failure. Operative intervention should not be delayed in those patients who encounter difficult or doubtful non-operative reduction.

Abstract
AIM OF STUDY The objective of this study is to determine the diagnostic value of the 24-h delayed film for Hirschsprung's disease (HD). Other features of the barium enema were also examined, in particular the correlation between the radiological transition zone (TZ) and the final pathology. METHODS All patients with suspected HD from 2003 to 2013 who had undergone barium enema and rectal biopsy were reviewed retrospectively to study the correlation between radiological features of barium enema with the final diagnosis as well as severity. RESULTS A total of 182 patients were admitted for suspected HD during the study period, of which 82 had both investigations done. 68 patients had radiological features suggestive of the disease and ultimately, 12 patients had the disease confirmed with rectal biopsy. Among those without radiological features of HD, 2 patients were found to have the disease. Thus, the sensitivity of the 24-h delayed film was 85.7 % and the specificity was 17.6 %. The positive predictive value (PPV) of this test was 20.6 % and the negative predictive value (NPV) was 85.7 %. Regarding the level of TZ, it was not detected in the barium enema in 7 (50 %) out of the 14 patients. For those with the presence of TZ, 6 (85.7 %) of them correlated well with the intra-operative findings and 4 (57.1 %) of them correlated well with the final histology. CONCLUSION The 24-h delayed film of barium enema has a high NPV and is useful to rule out HD. However, rectal biopsy is still suggested for disease confirmation given its low PPV. Lastly, once present, the level of radiological TZ is also a useful predictor for the actual disease involvement.
