Ten-Year Experience in the Prevention of Post-Kasai Cholangitis.

BACKGROUND: Cholangitis is the most common complication after the Kasai procedure. It can be life-threatening and may affect long- and short-term outcomes of children with biliary atresia. We summarize our experiences in the prevention of early-onset cholangitis. PATIENTS AND METHODS: From January 2002 to March 2013, children with biliary atresia (BA) who underwent the Kasai procedure in the General Surgical Department were included in a retrospective cohort study. These patients were divided into group A (therapy 1) and group B (therapy 2) depending on the infection prevention protocol and occurrences of cholangitis within the six months after surgery were recorded. Two hundred eighteen children were included in this cohort study. Seventy-six children (35 females and 41 males) were included in group A. One hundred forty-two children (65 females and 77 males) were included in group B. Therapy 1 was our primary protocol and included a third-generation cephalosporin, metronidazole, and human immunoglobulin. Therapy 2 was a modification of therapy 1 that involved imipenem-cilastatin and human immunoglobulin. Statistical analyses were performed. A p value below 0.05 was regarded as significant. RESULTS: In group A, 45 children developed cholangitis within the six months after the Kasai procedure. In group B, 14 of these children experienced post-operative cholangitis. A χ2 analysis was used to examine the difference in the incidence of cholangitis between groups A and B. There was a substantial difference in the morbidity of post-operative cholangitis between groups A and B (59.2% vs. 9.9%, p = 0.000). CONCLUSION: Cholangitis in the early period after a Kasai procedure can be prevented effectively with an advanced prophylactic protocol.

STROBE-anastomotic leakage after pull-through procedure for Hirschsprung disease.

This study was undertaken to explore the causes, diagnosis, and treatment of anastomotic leakage after pull-through (PT) procedure for Hirschsprung disease (HD).A retrospective analysis of patients with anastomotic leakage after a PT procedure in the General Surgery Department of Beijing Children's Hospital from July 2013 to June 2016 was undertaken. The surgical characteristics, diagnosis, and treatment were retrospectively analyzed.Among the 213 patients who underwent PT procedures, 5 patients had a documented anastomotic leakage. The median age of these 5 patients at the time of the PT procedure was 6.8 years old, and this was higher than those without anastomotic leakage (1.7 years old). In all patients, rectal examination in the lithotomy position revealed an anastomotic dehiscence at the 6 o'clock position. The abdominal ultrasonography demonstrated retrorectal pneumatosis with or without an abscess in 4 patients. All patients were treated with ileostomies and anastomotic resuturing. The median delay to management was 4 days (range: 1-29 days). Four patients (4/5, 80%) were cured, and 1 (delay, 29 days) of these 4 patients developed postoperative ileus. The remaining patient (delay, 9 days) was required to undergo a repeat PT procedure. For the 4 cured patients, the median follow-up time was 20 months (range: 15-37 months), and these patients defecated 3 times daily at most without soiling.Older children with HD might be prone to anastomotic leakage. The findings of the rectal examination and ultrasonography were distinctive and useful for the diagnosis. Early ileostomy and resuturing of the anastomosis could be used to treat anastomotic leakage.

Assessment of liver fibrosis by Fibroscan as compared to liver biopsy in biliary atresia.

AIM: To evaluate liver stiffness measurement (LSM) using non-invasive transient elastography (Fibroscan) in comparison with liver biopsy for assessment of liver fibrosis in children with biliary atresia (BA). METHODS: Thirty-one children with BA admitted to the Department of Pediatric Surgery of Beijing Children's Hospital from March 2012 to February 2013 were included in this study. Their preoperative LSM, liver biopsy findings, and laboratory results were studied retrospectively. RESULTS: The grade of liver fibrosis in all 31 patients was evaluated according to the METAVIR scoring system, which showed that 4 cases were in group F2, 20 in group F3 and 7 in group F4. There were 24 non-cirrhosis cases (F2-F3) and 7 cirrhosis cases (F4). In groups F2, F3 and F4, the mean LSM was 9.10 ± 3.30 kPa, 11.02 ± 3.31 kPa and 22.86 ± 12.43 kPa, respectively. LSM was statistically different between groups F2 and F4 (P = 0.002), and between groups F3 and F4 (P = 0.000), however, there was no statistical difference between groups F2 and F3 (P = 0.593). The area under the receiver operating characteristic curve of LSM for ≥ F4 was 0.866. The cut-off value of LSM was 15.15 kPa for ≥ F4, with a sensitivity, specificity, positive predictive value and negative predictive value of 0.857, 0.917, 0.750 and 0.957, respectively. CONCLUSION: Fibroscan can be used as a non-invasive technique to assess liver fibrosis in children with BA. The cut-off value of LSM (15.15 kPa) can distinguish cirrhotic patients from non-cirrhotic patients.

Anterior perineal fistulectomy in repairing H-type rectovestibular fistula with a normal anus in female children.

The purpose of this study was to review a 7-year operative experience of anterior perineal fistulectomy in repairing H-type rectovestibular fistula with a normal anus in female children. From January 2007 to December 2013, 105 female children with H-type rectovestibular fistula and a normal anus underwent anterior perineal fistulectomy in the Department of General Surgery, Beijing Children's Hospital, Capital Medical University. Clinical data were retrospectively analyzed. Patients' age ranged from 6 months to 13 years 10 months, with an average age 5 years 2 months. The clinical feature of this disease was a definite history of vestibular infection at about 30 days after birth and leakage of gas or loose stool through vestibular fistular orifice after the infection was controlled. All patients had a normal anus. Follow-up through telephone or outpatient visits from 6 months to 7 years (median, 5.2 years), showed that all the patients were continent and had regular bowel movements. Among the 105 patients, 97 (92.4%) gained primary healing with a satisfactory appearance; 8 (7.6%) patients relapsed, among which 5 healed after hip bathing treatment within 3 weeks, 2 required another anterior perineal fistulectomy 7 months later and were cured, and the last one had another anterior perineal fistulectomy 1 year 10 months later but relapsed again, which healed after hip bathing treatment within 3weeks after the second surgery. Anterior perineal fistulectomy is a simple, safe and reliable surgical method to treat H-type rectovestibular fistula with a normal anus.
