Challenge in diagnosis of late onset necrotizing enterocolitis in a term infant: a case report.

BACKGROUND: Necrotizing enterocolitis (NEC) is a common devastating inflammatory gastrointestinal disease and frequently occurs in premature infants. Here, we reported a case of late-onset NEC in a term neonate with good outcome after surgery for long-term follow-up. CASE PRESENTATION: Ten-week-old male came to emergency unit due to prolonged diarrhea and abdominal distention. He was born at gestational age of 40 weeks with birth weight and Apgar score of 2800 g and 7/8, respectively. He had no history of formula feeding. Two weeks before admitted to the hospital, the patient had frequent diarrhea with fever. He was found lethargic with abdominal distention, absence of bowel sounds and abdominal tenderness. Plain abdominal x-ray and CT scan showed gastric and intestinal dilatation and gasless colon, suggesting a small bowel obstruction, and bowel wall thickening indicating peritonitis, without any free subdiaphragmatic air (pneumoperitoneum). Moreover, the patient did not have a congenital heart disease. While in intensive medical treatment, he showed a continuous clinical deterioration. All findings were suggestive of intestinal inflammation with clinical deterioration, and we decided to perform an emergency exploratory laparotomy and found an ischemia along the jejunoileal with a perforation at 25 cm above the ileocecal valve. Subsequently, we performed a double-barrel ileostomy through a separate incision from the laparotomy. Histopathological findings confirmed the diagnosis of NEC. We closed the stoma at postoperative day 43. The patient was discharged uneventfully a month after stoma closure. CONCLUSION: Abdominal CT scan might be useful to establish an early recognition of late-onset NEC; thus, immediate surgical intervention might be performed to decrease its morbidity and mortality. Moreover, late-onset NEC in term neonates might occur without any risk factors or significant co-morbidities.

Prognostic Factors for Survival of Patients with Biliary Atresia Following Kasai Surgery.

Biliary atresia (BA) is a progressive obstruction and fibro-obliteration of the extrahepatic and intrahepatic biliary tract that causes cholestatic jaundice in infants, resulting in biliary cirrhosis and even death in the first year of life if the Kasai procedure is not performed at an earlier age. There are many prognostic factors that could affect the survival of patients with BA after Kasai surgery, however results still show some conflicting findings. A retrospective study was conducted using medical records of patients with BA who underwent Kasai surgery at Dr. Sardjito Hospital, Yogyakarta, Indonesia from June 2012 to April 2018. Twenty-nine BA patients were involved in our study, with 16 males and 13 females. Log-rank analysis showed a significant association between survival rate of BA patients with albumin level 1 month and 3 months after Kasai surgery, with p-values of 0.043 and 0.016, respectively. Interestingly, multivariate analysis revealed that cholangitis tended to have an association with BA patients' survival (p=0.09). In conclusion, the BA patients' survival might be affected by the presence of cholangitis after Kasai surgery. Further multicenter studies with a larger sample size are important to verify our results.

Postoperative enterocolitis assessment using two different cut-off values in the HAEC score in Hirschsprung patients undergoing Duhamel and Soave pull-through.

BACKGROUND: Hirschsprung-associated enterocolitis (HAEC) is the most severe and potentially lethal complication of Hirschsprung disease (HSCR) which might occur following definitive surgery. Our objectives were: 1) to compare the incidence of HAEC after Duhamel and Soave procedures using different cut-off values of the HAEC scoring method; and 2) to associate them with the risk factors, including sex, aganglionosis type, mothers' age at childbirth, gestational age, and mothers' educational level. METHODS: Medical records of patients with HSCR who underwent Soave and Duhamel procedures in our institution, Indonesia (January 2012 - December 2016) were reviewed retrospectively. Two cut-off values of the HAEC scoring system (i.e., ≥10 and ≥ 4) were utilized. RESULTS: Eighty-three patients with HSCR were recruited in this study (Soave: 37 males and 7 females vs. Duhamel: 28 males and 11 females; p = 0.18). The incidence of HAEC after surgery was 14/83 (16.9%) and 38/83 (45.8%) for cut-off values of ≥10 and ≥ 4, respectively (p = 0.00012), and tended to have an association with sex (p = 0.09). Although it was not statistically significant (p = 0.07), the frequency of HAEC after Soave procedure tended to be higher in patients with their mother's age of ≤35 years at childbirth than those with their mother's age of > 35 years (OR = 7.9; 95% CI = 0.9-72.1). Multivariate analysis indicated none of the risk factors were associated with the frequency of HAEC after definitive surgery. CONCLUSIONS: The lower cut-off value of ≥4 might increase the possibility to diagnose HAEC, particularly the mild cases. The incidence of HAEC after definitive surgery was not associated with any risk factors in our cohort patients. Further multicenter studies with a larger sample size are necessary to confirm our findings.

Histopathological findings for prediction of liver cirrhosis and survival in biliary atresia patients after Kasai procedure.

BACKGROUND: Without early recognition and Kasai procedure, biliary atresia (BA) results in liver cirrhosis and leads to either transplantation or death at a young age. We aimed to characterize the liver histopathological findings for prediction of cirrhosis and survival in BA patients after Kasai surgery. METHODS: We retrospectively reviewed all histopathological results for BA patients who underwent liver biopsy during Kasai surgery from August 2012 to December 2018 in Dr. Sardjito Hospital, Yogyakarta, Indonesia. RESULTS: Fifty infants with BA were ascertained in our study, of whom 27 were males and 23 were females. The median age of Kasai procedure was 102.5 days (interquartile range (IQR), 75.75-142.25 days). There were 33 (66%) and 17 (34%) BA patients with and without liver cirrhosis, respectively, while the overall survival was 52%. The patients with a severe bile duct proliferation, severe cholestasis, and severe portal inflammation have a higher risk by 27-, 22-, and 19.3-fold, respectively, to develop liver cirrhosis compared with patients with a moderate/mild bile duct proliferation, moderate/mild/without cholestasis, and moderate/mild portal inflammation, respectively (p = 3.6 × 10- 6, 5.6 × 10- 4, and 1.6 × 10- 3, respectively), while the giant cell transformation was not associate with the development of liver cirrhosis (p = 0.77). The bile duct proliferation was strongly correlated with cholestasis and portal inflammation (p = 7.3 × 10- 5 and 2 × 10- 4, respectively), and cholestasis was also significantly correlated with portal inflammation (p = 0.016). Interestingly, the age at Kasai procedure was strongly associated with the development of liver cirrhosis (p = 0.02), but not with the patients' survival (p = 0.33), while the degree of fibrosis and cholestasis were significantly correlated with the patients' survival, with HR of 3.9 (95% CI = 1.7-9.0; p = 0.017) and 3.1 (95% CI = 1.4-7.0; p = 0.016), respectively. CONCLUSIONS: Histopathological findings of bile duct proliferation, cholestasis, and portal inflammation can predict the liver cirrhosis development in patients with BA. Furthermore, degree of fibrosis and cholestasis affect the patients' survival following the Kasai operation.

Aberrant UBR4 expressions in Hirschsprung disease patients.

BACKGROUND: Recently, pathogenic alleles within ubiquitin N-recognin domain-containing E3 ligase 4 (UBR4) gene have been shown to be associated with Hirschsprung disease (HSCR). We determined the UBR4 expressions in Indonesian HSCR patients. METHODS: We analyzed the UBR4 expressions in the colons of HSCR patient and anorectal malformation (ARM) patient as control by real-time polymerase chain reaction (qPCR). RESULTS: Thirty-seven patients with non-syndromic HSCR and eighteen controls were involved in this study. qPCR revealed that the UBR4 expression was strongly decreased (0.77-fold) in the ganglionic group of patients with HSCR compared to the control group with ARM (ΔCT 2.43 ± 0.36 vs. 2.05 ± 0.69; p = 0.009), whereas the UBR4 expression was also significantly reduced (0.79-fold) in the aganglionic group of patients with HSCR compared to the control group with ARM (ΔCT 2.39 ± 0.46 vs. 2.05 ± 0.69; p = 0.044). However, the UBR4 expression change was not associated with gender (p = 0.35 and 0.80), nor with degree of aganglionosis both in ganglionic and aganglionic colons (p = 0.72 and 0.73), respectively. CONCLUSION: Our study demonstrates that expression of UBR4 is decreased in both aganglionic and ganglionic colon of HSCR patients.
