RESUMO

BACKGROUND: To assess the quality change of our single-center pediatric colonoscopy after applying bundle for bowel preparation and general anesthesia and centralize the procedure using terminal ileum (TI) intubation rate as the main indicator. METHODS: All elective colonoscopies performed for patients younger than 18 years old in MacKay Memorial Hospital from July 2015 through June 2020 (assigned to group 1, before bundle) and from August 2020 through July 2021 (assigned to group 2, after bundle) were retrospectively reviewed for demographic characteristics, indications, bowel preparation agent and cleansing level, diagnostic and therapeutic procedures, maximum intestinal level reached, and cecal intubation and total procedure time. Statistical analysis was done using P value < 0.05 considered to be significant. RESULTS: Analysis included 45 and 32 colonoscopies in group 1 and 2, respectively. Bloody stool was the most frequent indication in both groups. Both TI intubation rate (42.2 % vs. 75.0 %, P = 0.004) and biopsy rate (45.0 % vs. 75.9 %, P = 0.01) increased significantly from group 1 to group 2. The narrower standard deviation of bowel preparation score (1.93 vs. 1.15) and total procedure time (37.71 vs. 22.29) in group 2 indicated a more stable quality, although the mean showed no difference. There was no statistical difference in age, gender, body weight, cecal intubation rate, or cecal intubation time. CONCLUSION: A higher TI intubation rate and biopsy rate indicated an improved quality of pediatric colonoscopy after applying bundle including bowel preparation and general anesthesia, with additional centralization.

RESUMO

Heterotopic pancreas (HP) is defined as pancreatic tissue lacking vascular or anatomic connection with the normal pancreas. Surgical resection is often indicated for symptomatic gastric HP. However, intraoperative identification of gastric HP is often difficult during laparoscopic surgery. Herein, we describe a patient with gastric HP, which was marked with SPOT® dye (GI Supply, Camp Hill, PA, USA). The dye was seen clearly laparoscopically facilitating total excision of the lesion. The final pathology report confirmed the presence of heterotopic pancreatic tissue including pancreatic acini, small pancreatic ducts tissue with islets of Langerhans in the deep gastric submucosal area. There were no postoperative complications, and the patient was symptom-free. To the best of our knowledge, this was the first case report in the literature in which endoscopic tattooing of gastric HP before laparoscopic resection was performed. This method of localization was simple and reliable in children.

RESUMO

RATIONALE: Extraosseous Ewing's sarcoma is a rare tumor which is aggressive with poor prognosis; it can occur anywhere in the body, but scantily in the pancreas. Pancreatic Ewing's sarcoma is not reported commonly, with inconsistent clinical manifestations. In this regard, early recognition of this disease is very important for the patient's sake. PATIENT CONCERNS: A 16-year-old boy presented with left lower quadrant abdominal pain for 2 months, and left flank pain with dysuria for 1 month. DIAGNOSIS: Abdominal and renal ultrasonography found a mass between the spleen and left kidney as well as left renal pelvic dilatation. Abdominal computed tomography found a heterogenous mass derived from the tail of the pancreas. Serial examinations revealed that the mass was a pancreatic Ewing's sarcoma. Furthermore, no metastasis was documented. INTERVENTIONS: The tumor was totally excised after 6 months of chemotherapy, which included 10 courses of neoadjuvant chemotherapy with vincristine, epirubicin, and cyclophosphamide, alternating with ifosfamide and etoposide. The patient completed consolidation chemotherapy with vincristine, epirubicin, and cyclophosphamide, alternating with ifosfamide and etoposide for 5 courses. Radiotherapy was applied to the tumor-involved region and tumor bed. OUTCOMES: To date, the malignancy has not recurred since the treatment was completed 4 years ago. There are no complications from the treatment for the patient. LESSONS: The pancreas is a very rare extraosseous location for Ewing's sarcoma. Pancreatic extraosseous Ewing's sarcoma should be regarded as a differential diagnosis of non-urinary originated left flank pain with dysuria in adolescents.

RESUMO

While serous cystadenomas of the pancreas usually consist of small cysts, one rare variant has been reported to be composed of macrocysts. Herein, we present the case of the youngest patient with macrocystic serous cystadenoma (MSC) to be reported in the literature. The patient was a 17-year-old girl who presented with the major symptoms of a palpable abdominal mass accompanied by epigastric pain and vomiting for several months. A potential malignancy could not be excluded on the basis of imaging studies, which showed a large macrocystic pancreatic tumor that was 7 cm in diameter. Owing to the patient's symptoms, after diagnosing the mass as a pancreatic cystic tumor with potential malignancy and large tumor size, surgical intervention was arranged. Pathological analysis of the biopsy sample suggested MSC. By reviewing the literature, we found several unique characters of MSCs that cause them to be frequently misdiagnosed as potential malignancies. Additionally, the age of MSC occurrence was found to be lower than of general serous cystadenomas. The potential of MSC should be kept in mind by clinicians when diagnosing young people with pancreatic macrocystic lesions.

RESUMO

Refractory anemia is not uncommon in pediatric patients, and anemia caused by gastrointestinal tract bleeding should always be kept in mind. Aside from infection or intestinal malrotation related bleeding, vascular malformation should also be considered. Blue rubber bleb nevus syndrome (BRBNS) is a rare vascular disorder consisting of multiple venous malformations. Lack of experience in pediatric BRBNS might lead to delayed diagnosis or misdiagnosis. Herein, we report a case of an eleven-year-old boy with recurrent pallor appearance and weakness diagnosed with BRBNS. After a thorough examination, he was treated with endoscopic polypectomy, and further iron supplements and folic acid. He is now under regular follow-up at our outpatient department. No complication is noted for six months. BRBNS is a rare venous malformation syndrome that mostly involves skin and the gastrointestinal tract. Multidisciplinary approach should be arranged for diagnosis and management. Up to date, no consensus for BRBNS treatment has been reached. Management usually depends on clinical symptoms and severity of damage of involved organs. The options of treatment include conservative, medical, endoscopic, and surgical management.

RESUMO

RATIONALE: Infantile inflammatory bowel disease (IBD) is an extremely rare subgroup of IBD that includes patients whose age of onset is younger than 2 years old. These patients can have more surgical interventions, and a severe and refractory disease course with higher rates of conventional treatment failure. Monogenic defects play an important role in this subgroup of IBD, and identification of the underlying defect can guide the therapeutic approach. PATIENT CONCERNS: In 2007, a 4-month-old girl from a nonconsanguineous family presenting with anal fistula, chronic diarrhea, and failure to thrive. She underwent multiple surgical repairs but continued to have persistent colitis and perianal fistulas. DIAGNOSIS: Crohn's disease was confirmed by endoscopic and histologic finding. INTERVENTION: Conventional pediatric IBD therapy including multiple surgical interventions and antitumor necrosis factor alpha agents were applied. OUTCOMES: The patient did not respond to conventional pediatric IBD therapy. Interleukin-10 (IL-10) receptor mutation was discovered by whole-exome sequencing and defective IL-10 signaling was proved by functional test of IL-10 signaling pathway by the age of 12. The patient is currently awaiting hematopoietic stem cell transplantation. LESSONS: Early detection of underlying genetic causes of patients with infantile-IBD is crucial, since it may prevent patients from undergoing unnecessary surgeries and adverse effects from ineffective medical therapies. Moreover, infantile-IBD patients with complex perianal disease, intractable early onset enterocolitis and extraintestinal manifestations including oral ulcers and skin folliculitis, should undergo genetic and functional testing for IL-10 pathway defect.

RESUMO

BACKGROUND: Intestinal mucositis remains one of the most deleterious side effects in cancer patients undergoing chemotherapy. We hypothesize that the probiotics could preserve gut ecology, ameliorate inflammation, and protect epithelia via immune modulations of enterocytes and intestinal stem cells. Our aim is to characterize these changes and the safety of probiotics via a 5-fluorouracil- (5-FU-) induced intestinal mucositis mouse model. METHODS: 5-FU-injected BALB/c mice were either orally administrated with saline or probiotic suspension of Lactobacillus casei variety rhamnosus (Lcr35). Diarrhea scores, serum proinflammatory cytokines, and T-cell subtypes were assessed. Immunostaining analyses for the proliferation of intestinal stem cells CD44 and Ki67 were processed. Samples of blood and internal organs were investigated for bacterial translocation. RESULTS: Diarrhea was attenuated after oral Lcr35 administration. Serum proinflammatory cytokines were significantly increased in the 5-FU group and were reversed by Lcr35. A tremendous rise of the CD3+/CD8+ count and a significant decrease of CD3+CD4+/CD3+CD8+ ratios were found in the 5-FU group and were both reversed by Lcr35. 5-FU significantly stimulated the expression of CD44 stem cells, and the expression was restored by Lcr35. 5-FU could increase the number of Ki67 proliferative cells. No bacterial translocation was found in this study. CONCLUSIONS: Our results showed that 5-FU caused intestinal inflammation mainly via Th1 and Th17 responses. 5-FU could stimulate stem cells and proliferation cells in a mouse model. We demonstrate chemotherapy could decrease immune competence. Probiotics were shown to modulate the immune response. This is the first study to analyze the immune modulation effects and safety of Lactobacillus strain on enterocytes and intestinal stem cells in a mouse model.

RESUMO

BACKGROUND: Gallstones are uncommon in infants and children and Asian children are thought to have very low risk. Diagnoses have increased in recent years with the widespread use of ultrasonography (USG). This study aimed to review our experience with risk factors, complications, and treatment of pediatric gallstones in low-incidence populations. METHODS: We retrospectively reviewed patients younger than 18 years old diagnosed with gallstones using USG between November 2006 and December 2012 in a tertiary referral hospital in Taiwan. Demographic information including age and sex, follow-up period, USG findings, predisposing factors, complications, treatment approaches and outcomes were recorded. RESULTS: Ninety-eight children with gallstones diagnosed with USG were enrolled and reviewed in our study. Females comprised 55% of patients, with no specific gender tendency. No risk factor could be identified in 30.8% of patients. The most common risk factors were cephalosporin (CS) use, presence of a choledochal cyst (CC), and spherocytosis. CS use was not associated with a higher dissolution rate. The presence of type IVa CC implied a high rate of gallstone recurrence after Roux-en-Y hepaticojejunostomy. Complications were seen in 22.4% of patients, but only two needed emergency stone removal. Expectant management was performed in 61% of patients and 62.5% of them achieved spontaneous resolution; the stone dissolution rate was not lower than in the group treated with ursodeoxycholic acid (UDCA). Stone size was significantly decreased after UDCA use if resolution did not occur. CONCLUSIONS: Pediatric gallstones showed high resolution rate, and the clinical course was largely benign. CS use was the most common risk factor and did not predict a higher dissolution rate. Type IVa CC was also an important risk factor associated with a high recurrence rate. Conservative treatment and oral UDCA may be reasonable strategies in most patients, unless complications are present.

RESUMO

FOLFOX (5-fluorouracil, leucovorin, and oxaliplatin), a 5-fluorouracil (5-FU)-based chemotherapy regimen, is one of most common therapeutic regimens for colorectal cancer. However, intestinal mucositis is a common adverse effect for which no effective preventive strategies exist. Moreover, the efficacy and the safety of fecal microbiota transplants (FMT) in cancer patients treated with anti-neoplastic agents are still scant. We investigated the effect of FMT on FOLFOX-induced mucosal injury. BALB/c mice implanted with syngeneic CT26 colorectal adenocarcinoma cells were orally administered FMT daily during and two days after five-day injection of FOLFOX regimen for seven days. Administration of FOLFOX significantly induced marked levels of diarrhea and intestinal injury. FMT reduced the severity of diarrhea and intestinal mucositis. Additionally, the number of goblet cells and zonula occludens-1 decreased, while apoptotic and NF-κB-positive cells increased following FOLFOX treatment. The expression of toll-like receptors (TLRs), MyD88, and serum IL-6 were upregulated following FOLFOX treatment. These responses were attenuated following FMT. The disrupted fecal gut microbiota composition was also restored by FMT after FOLFOX treatment. Importantly, FMT did not cause bacteremia and safely alleviated FOLFOX-induced intestinal mucositis in colorectal cancer-bearing mice. The putative mechanism may involve the gut microbiota TLR-MyD88-NF-κB signaling pathway in mice with implanted colorectal carcinoma cells.

RESUMO

BACKGROUND AND AIM: Intestinal mucositis remained one of the most deleterious complications in cancer patients undergoing chemotherapy. 5-FU treatment was reported to affect the abundance of gut microbiota and cause mucositis, which might be ameliorated by probiotics. We investigate the potential changes of 5-FU treatment and the modulations of probiotics on gut microbiota in a mouse model. METHODS: Male BALB/c mice received either 5-FU or saline (S). They were separated and fed saline, Lactobacillus casei variety rhamnosus (Lcr) and Lactobacillus reuteri DSM 17938 (BG). Lcr and BG were simultaneously administered with 5-FU for 5 days. Stool specimens were collected for DNA extraction and pyrosequenced for bioinformatic analysis. RESULTS: Fecal microbial communities were obviously diverse. Bacteroides and Bacteroidaceae were the most abundant microbiota in FU.BG group while S24_7 was the most in S.S group. At phylum and class levels, abundances of Betaproteobacteria, Erysipelotrichi, Gammaproteobacteria, and Verrucomicrobia were significantly increased in the FU groups. Probiotics supplementation did increase the abundances of Enterobacteriales and Turicibacterales. We demonstrated that probiotics did modulate the abundance and diversity of gut microbiota. Bacterial motility proteins were found enriched and upregulated in the S.BG group. No mortality was noted. No bacterial translocation was found in spleen and blood among the six groups. CONCLUSION: Gut microbiota of mice undergoing chemotherapy exhibited a distinct disruption in bacterial composition. Probiotic did modulate the abundance and diversity of gut microbiota. This is the first study to analyze the effects and safety of Lactobacillus strains on 5-FU-induced mucositis systematically and assess changes in the intestinal microbiota after probiotic intervention.

RESUMO

Advancements in diagnostic modalities have improved the diagnosis of meconium peritonitis (MP) both in utero and ex utero. This study aimed to determine the efficacy of prompt prenatal and postnatal diagnoses of MP on the postnatal outcomes of these patients.We conducted a retrospective chart review of neonates with MP admitted to the Mackay Memorial Hospital Systems from 2005 to 2016. The prenatal diagnoses, postnatal presentations, surgical indications, operative methods, types of MP, operative findings, associated anomalies, morbidities, patient outcomes, and survival rates were analyzed. Morbidities included postoperative adhesion ileus, bacteremia, and short bowel syndrome. We also performed subgroup analyses of the morbidity and survival rates of prenatally versus postnatally diagnosed patients, as well as inborn versus outborn neonates.Thirty-seven neonates with MP were enrolled. Of this number, 24 (64.9%) were diagnosed prenatally. Twenty-two (59.5%) were born preterm. The most common prenatal sonographic findings included fetal ascites followed by dilated bowel loops. Abdominal distention was the most frequent postnatal symptom. Thirty-four (91.9%) neonates underwent surgery, whereas 3 were managed conservatively. Volvulus of the gastrointestinal tract was the most frequent anatomic anomaly. The total morbidity and survival rates were 37.8% and 91.9%, respectively. The morbidity and survival rates did not differ significantly between prenatally and postnatally diagnosed patients (37.5% vs 33.3%, P = 1.00; 91.7% vs 92.3%, P = 1.00, respectively). Inborn and outborn patients did not differ in terms of morbidity and survival rates (27.3% vs 53.3%, P = .17; 100% vs 80.0%, P = .06, respectively).Although not statistically significant, inborn MP neonates had higher survival rates when compared with outborn MP neonates. Prompt postnatal management at tertiary centers seemed crucial.

RESUMO

Severe vitamin D deficiency may cause rickets in infants or children and osteomalacia in adults, though it is now uncommon in developed countries. However, subclinical vitamin D deficiency is more prevalent, and it is associated with osteoporosis and higher incidence of falls or fractures. It was reported that 96% children with rickets were breastfed, since breast milk contains inadequate vitamin D. The American Academy of Pediatrics 2008 recommended infants who were exclusively or partially breastfed required 400 international units vitamin D daily from the first few days of life. Furthermore, since vitamin D receptors are present all over the body, insufficient vitamin D status may correlate with several extra-skeletal effects, such as pregnancy-related complications and immune dysfunction. This paper discusses the researches regarding system-based vitamin D effects, the possible risk factors leading to vitamin D deficiency, and the recommendations of vitamin D requirements. It is well-known that vitamin D can be obtained by sun exposure or limited natural dietary sources. The American Academy of Dermatology declared ultraviolet radiation to be a known skin carcinogen, so it may not be safe or efficient to obtain vitamin D via sun exposure or other artificial sources. Therefore, many pediatricians and physicians recommend appropriate vitamin D supplementation to achieve optimal plasma concentration. Trials assessing the effects of vitamin D repletion and establishing its optimum serum level are ongoing. Medical advice for vitamin D supplementation should be individualized accordingly.

RESUMO

BACKGROUND: For chemotherapy patients, intestinal mucositis is a frequent complication. Previously, we evaluated the beneficial effect of oral probiotics in 5-Fluorouracil (5-FU) induced mucositis in BALB/c mice. Here, we used SCID/NOD mice instead to simulate the immunodeficiency of chemotherapy patients: first, to evaluate the safety of probiotic supplementation and second, to determine the probiotic effect in response to 5-FU intestinal mucositis. METHODS: Thirty-six SCID/NOD mice were injected with saline (three control groups) or 5-FU (three experimental groups) intraperitoneally daily for five days. Mice were given either oral saline daily, probiotic suspension of Lactobacillus casei variety rhamnosus (Lcr35, Antibiophilus™, France) or Lactobacillus acidophilus and Bifidobacterium bifidum (LaBi, Infloran™, Italy). Blood, liver, spleen, and lymph node tissue samples were evaluated for probiotic translocation via culture and Q-PCR. Weight change, diarrhea score, jejunal villus height (VH) and crypt depth (CD), and serum cytokine levels of TNF-α, IFNγ, IL-1ß, IL-6, IL-4, IL-10, IL-13, and IL-17 were also assessed. RESULTS: No weight loss was found in the SCID control group. Mean weight loss of 10.63 ± 0.87% was noted by day five in 5-FU group without probiotics but it was only 6.2 ± 0.43% if mice were given Lcr35 (p < 0.01) and 7.1 ± 1.80% (p < 0.01) if they were given LaBi. Diarrhea score of 5-FU group without probiotics was 2.0 ± 0.0 by day five, which dropped to 1.33 ± 0.17 (p < 0.05) and 1.42 ± 0.24 (p < 0.05) with Lcr35 and LaBi, respectively. Average VH significantly decreased and CD significantly increased in SCID mice given 5-FU. With probiotics, average CD improved (p < 0.05) while VH lengthened as well. Besides IL-13, all cytokine levels increased in 5-FU SCID mice. Both Lcr35 and LaBi significantly inhibited serum cytokines (p < 0.05). No probiotic strains were detected in blood cultures of any mice. CONCLUSION: Using SCID/NOD mice as a novel model for 5-FU induced intestinal mucositis, we find that probiotics Lcr35 and LaBi do not lead to bacteremia, can improve diarrhea and body weight, can restore jejunal crypt depth, and significantly inhibit cytokines TNF-α, IL-1ß, IFNγ, IL-6, IL-4, IL-10, and IL-17.

RESUMO

Adjuvant 5-fluorouracil (5-FU)-based chemotherapy, including FOLFOX (5-FU, leucovorin, and oxaliplatin), is recommended for colorectal cancer. However, intestinal mucositis remains a common adverse effect for which no effective preventive strategies are available. To develop a convenient and novel way to alleviate mucositis, we investigated the effect of Lactobacillus casei variety rhamnosus (Lcr35) on FOLFOX-induced mucosal injury. BALB/c mice subcutaneously injected with syngeneic CT26 colorectal adenocarcinoma cells were orally administered Lcr35 daily before, during, and after 5-day injection of FOLFOX regimen, for 14 days. The following methods were used: diarrhea score for toxicity, ELISA for cytokine production, histopathology for intestinal injury, immunohistochemistry for apoptosis/proliferation and regulatory proteins, RT-PCR for cytokine mRNA expression, and DNA sequencing for fecal gut microbiota. FOLFOX administration to colorectal cancer-bearing mice significantly inhibited tumor growth and the accompanying marked diarrhea and intestinal injury histologically characterized by the shortening of villi and destruction of intestinal crypts. Preventive administration of Lcr35 dose-dependently reduced the severity of diarrhea and intestinal mucositis without affecting the anti-tumor effect of FOLFOX. The numbers of apoptotic, NF-κB-, and BAX-activated cells increased after FOLFOX, and these responses were mitigated by Lcr35. TNF-α and IL-6 upregulation by FOLFOX treatment was attenuated by Lcr35. The fecal gut microbiota composition of Firmicutes and Bacteroidetes disturbed by FOLFOX was significantly reversed by Lcr35 toward a preferential profile. In conclusion, the oral probiotic Lcr35 prevented FOLFOX-induced intestinal mucositis in colorectal cancer-bearing mice. The putative mechanism might involve modulation of gut microbiota and proinflammatory responses with suppression of intrinsic apoptosis in intestinal injury.

RESUMO

RATIONALE: Septo-optic dysplasia (SOD) is a rare congenital disorder that may cause jaundice in infants. However, it is usually prone to neglect and misdiagnosis in infants with cholestasis because endocrine disorder such as panhypopituitarism is rare in the cause of infantile cholestasis. We report a case of SOD concurrent with acquired cytomegalovirus (CMV) infection, who presented with prolonged jaundice as the first clinical sign. PATIENT CONCERNS: The patient was a 2-month-old male infant who presented with cholestasis, combined with fever and panhypopituitarism. DIAGNOSES: He was diagnosed with SOD and acquired CMV infection. INTERVENTIONS: He was treated with hormone replacement therapy and ganciclovir. OUTCOMES: After correction of the pituitary hormone deficiency and ganciclovir treatment, significant improvements of cholestasis, retinal lesions, and growth rate were seen in our patient. LESSONS: Although an endocrine disorder such as panhypopituitarism is rare in the cause of neonatal or infantile cholestasis, we must keep this reason in mind.

RESUMO

We report a 7-year-old Taiwanese girl with acute pancreatitis (AP) complicated with pseudocyst (PC). The girl was found to have a PC by ultrasonograpgy (USG) and magnetic resonance imaging 14 days after the onset of AP. The girl was discharged 21 days after management with an asymptomatic PC. The diagnostic criteria of AP included abdominal pain, serum amylase or lipase level, and imaging findings. Transabdominal USG after appropriate preparation with adequate fasting, intake of some liquids during the scanning, and right decubitus position enhance the demonstration of pancreas and peripancreatic structures. PC could be seen in up to 38% of pediatric AP patients. It can form within 2 weeks after the onset of symptoms, although most are late complications. Pancreatic PCs have to be differentiated from other intra-abdominal cysts on USG according to their image character and anatomic location. A well-prepared USG examination in combination with liquid intake and right decubitus position is of value in the diagnosis and follow-up of PC.

RESUMO

BACKGROUND: Juvenile polyposis syndrome, a rare disorder in children, is characterized with multiple hamartomatous polyps in alimentary tract. A variety of manifestations include bleeding, intussusception, or polyp prolapse. In this study, we present an 8-month-old male infant of juvenile polyposis syndrome initially presenting with chronic anemia. To the best of our knowledge, this is the youngest case reported in the literature. METHODS: We report a rare case of an 8-month-old male infant who presented with chronic anemia and gastrointestinal bleeding initially. Panendoscopy and abdominal computed tomography showed multiple polyposis throughout the entire alimentary tract leading to intussusception. Technetium-99m-labeled red blood cell (RBC) bleeding scan revealed the possibility of gastrointestinal tract bleeding in the jejunum. Histopathological examination on biopsy samples showed Peutz-Jeghers syndrome was excluded, whereas the diagnosis of juvenile polyposis syndrome was established. RESULTS: Enteroscopic polypectomy is the mainstay of the treatment. However, polyps recurred and occupied the majority of the gastrointestinal tract in 6 months. Supportive management was given. The patient expired for severe sepsis at the age of 18 months. CONCLUSION: Juvenile polyposis syndrome is an inherited disease, so it is not possible to prevent it. Concerning of its poor outcome and high mortality rate, it is important that we should increase awareness and education of the parents at its earliest stages.

RESUMO

Biliary atresia (BA) is a significant liver disease in children. Since 2004, Taiwan has implemented a national screening program that uses an infant stool color card (SCC) for the early detection of BA. The purpose of this study was to examine the outcomes of BA cases before and after the launch of this screening program. The objectives of this study were to evaluate the rates of hospitalization, liver transplantation (LT), and mortality of BA cases before and after the program, and to examine the association between the hospitalization rate and survival outcomes.This was a population-based cohort study. BA cases born during 1997 to 2010 were identified from the Taiwan National Health Insurance Research Database. Sex, birth date, hospitalization date, LT, and death data were collected and analyzed. The hospitalization rate by 2 years of age (Hosp/2yr) was calculated to evaluate its association with the outcomes of LT or death.Among 513 total BA cases, 457 (89%) underwent the Kasai procedure. Of these, the Hosp/2yr was significantly reduced from 6.0 to 6.9/case in the earlier cohort (1997-2004) to 4.9 to 5.3/case in the later cohort (2005-2010). This hospitalization rate reduction was followed by a reduction in mortality from 26.2% to 15.9% after 2006. The Cox proportional hazards model showed a significant increase in the risk for both LT (hazard ratio [HR] = 1.14, 95% confidence interval [CI] = 1.10-1.18) and death (HR = 1.05, 95% CI = 1.01-1.08) for each additional hospitalization. A multivariate logistic regression model found that cases with a Hosp/2yr >6 times had a significantly higher risk for both LT (adjusted odds ratio [aOR] = 4.35, 95% CI = 2.82-6.73) and death (aOR = 1.75, 95% CI = 1.17-2.62).The hospitalization and mortality rates of BA cases in Taiwan were significantly and coincidentally reduced after the launch of the SCC screening program. There was a significant association between the hospitalization rate and final outcomes of LT or death. The SCC screening program can help reduce the hospitalization rate and mortality of BA cases and bring great financial benefit.
