  • Inspissated bile syndrome (IBS) is a rare condition in which thick intraluminal bile, including bile plugs, sludge, or stones, blocks the extrahepatic bile ducts in an infant. A 5-week-old female infant was admitted for evaluation of jaundice and acholic stool. Diagnostic tests, including ultrasound sonography, magnetic resonance cholangiopancreatography, and a hepatobiliary scan, were not conclusive. Although the diagnosis was unclear, the clinical and laboratory findings improved gradually on administration of urodeoxycholic acid and lipid emulsion containing omega-3 polyunsaturated fatty acids (PUFAs) for 3 weeks. However, a liver biopsy was suggestive of biliary atresia. This finding forced us to perform intraoperative cholangiography, which revealed a patent common bile duct with impacted thick bile. We performed normal saline irrigation and the symptom was improved, the final diagnosis was IBS. Thus, we herein report that IBS can be treated with omega-3 PUFAs as an alternative to surgical intervention.

  • 카롤리병은 섬유낭성 간질환이다. 상염색체 열성 장애로 담관의 선천적 다발성 확장이 특징이다. 카롤리병을 진단하는 방법으로 전산화단층촬영, 자기공명영상 검사, 담관 조영술, 초음파 검사가 있다. 전산화단층촬영검사는 섬유다낭성 간 질환을 감지하고 구별하는데 필수적이며, 간 내 담관의 확장을 판별하는 데 유용하다. 하지만 조영제를 사용함으로써 일어날 수 있는 부작용에 대한 인지가 필요하다. 자기공명영상검사는 대표적으로 자기공명담췌관조영술 방법을 이용한다. 비침습적 검사로 환자의 고통을 경감할 수 있고, 담췌관부의 해부학적 구조와 병변 유무를 쉽고 빠르게 관찰이 가능하다. 담관 조영술은 비대해진 담관 전체에 걸친 여러 낭성 확장을 직접 시각화할 수 있는 효과적인 진단 방법이다. 하지만 이 시술 또한 침습적인 시술이므로 진단이 아닌 치료 목적으로 권장된다. 초음파 검사는 전산화단층촬영과 유사한 소견을 확인할 수 있다. 간동맥 뿌리는 기존의 그레이 스케일 초음파에서 증명하기 쉽지 않다. 하지만 관 내 혈관 뿌리를 가진 확장된 담관을 묘사할 수 있을 뿐만 아니라 관 내 색상 도플러 신호를 쉽게 식별할 수 있다는 점에서 임상적 가치를 갖고 있다. 최근엔 영상진단의 발전으로 전산화단층촬영 검사, 자기공명영상 검사, 담관 조영술, 초음파 검사 등으로 조기 진단이 가능해졌다. 조기 진단을 통해 치료 후에 장기적인 예후가 개선될 수 있도록 영상 진단 발전에 더욱 기여하고자 각 검사별 카롤리병에 대하여 어떠한 양상이 나타나는지 고찰하였다

  • Purpose: Choledochal cyst is a cystic dilatation of common bile duct. Although the etiology is presently uncertain, anomalous pancreaticobiliary ductal union (APBDU) is thought to be a major etiology of choledochal cyst. In this study, we analyzed the clinical and anatomical characteristics and pathologies of patients diagnosed with choledochal cyst in a single institute for 25 years. Methods: A total of 113 patients, diagnosed with choledochal cyst and who received an operation in Severance Children's Hospital from January 1988 to May 2013, were included. Medical records were reviewed, including clinical and demographic data, surgical procedures. Abdominal ultrasonography, magnetic resonance cholangiopancreatography, and intraoperative cholangiography were used as diagnostic tools for evaluation and classification of choledochal cyst and the presence of anomalous pancreaticobiliary ductal union. Todani's classification, and relationship between APBDU and surgical pathology. Results: Among 113 patients, 77 patients (68.1%) presented symptoms such as hepatitis, pancreatitis and/or cholecystitis. Eighty three patients (73.5%) had APBDU, and 94 patients (83.2%) showed inflammatory pathologic changes. APBDU, pathologic inflammation, and serological abnormalities such as hepatitis or pancreatitis showed a statistically significant correlation to one another. Conclusion: APBDU is thought to be one of the etiologic factors of choledochal cyst. It is related to the inflammatory changes in bile duct that can lead to the cystic dilatation.

  • Backgrounds/Aims: Double duct sign (DDS) (dilated common bile and pancreatic duct) is synonymous with pancreatic head/peri-ampullary tumor (PHPAT). There is limited evidence on whether incidental DDS (I-DDS) is associated with an increased risk of malignancy. This study aimed to evaluate 5-year outcomes of I-DDS. Methods: Patients were categorized according to their risk of malignancy. 'Low-risk' patients, including those with I-DDS between 2010 and 2015, were analyzed in this study. The primary outcome was incidence of PHPAT within five years of identification of DDS. Histology results from endoscopic ultrasound-guided biopsy were considered diagnostic. Secondary outcomes were incidence of benign causes, extent of follow-up investigations, and clinical indicators of malignancy in patients with DDS. Results: Among 103 patients with DDS, 20 had I-DDS. Subsequent follow-up of these 20 patients found no patient with PHPAT, two (10%) patients with chronic pancreatitis, and 18 (90%) patients with no cause found. The median follow-up duration for 'low-risk' patients was 7.3 years (range, 6-11 years). The mean number of follow-up investigations per patient was two (range, 0-9). Investigations included computed tomography (n = 27), magnetic resonance cholangiopancreatography (n = 23), endoscopy (n = 16), and ultrasound (n = 14). Patients with jaundice were more likely to have malignancy (p < 0.01). Those with abdominal pain were more likely to have a benign cause (p < 0.01). Hyperbilirubinemia and/or deranged liver enzymes and raised CA19-9 were more likely to be associated with PHPAT (p < 0.01). Conclusions: Patients with I-DDS have a low risk of developing PHPAT within five years.

  • Background/Aims: Endoscopic evaluation of intraductal papillary mucinous neoplasms (IPMNs) is useful in determining whether the lesions are benign or malignant. This study aimed to examine the usefulness of peroral pancreatoscopy (POPS) in determining the prognosis of IPMNs. Methods: POPS with videoscopy was performed using the mother-baby scope technique. After surgery, computed tomography/magnetic resonance cholangiopancreatography or ultrasonography and blood tests were performed every 6 months during the follow-up. Results: A total of 39 patients with main pancreatic duct (MPD)-type IPMNs underwent POPS using a videoscope, and the protrusions in the MPD were observed in 36 patients. The sensitivity and specificity of cytology/biopsy performed at the time of POPS were 85% and 87.5%, respectively. Of 19 patients who underwent surgery, 18 (95%) patients had negative surgical margins and 1 (5%) patient had a positive margin. Conclusions: In IPMNs with dilatation of the MPD, POPS is considered effective if the lesions can be directly observed. The diagnosis of benign and malignant lesions is possible depending on the degree of lesion elevation. However, in some cases, slightly elevated lesions may increase in size during the follow-up or multiple lesions may be simultaneously present; therefore, careful follow-up is necessary.

  • 담낭암은 진행된 상태에서 발견되었을 경우 예후가 매우 불량한 암으로 전신항암화학요법으로 치료를 하게 되나 일반적으로 고식적인 역할에 그치는 경우가 대부분이다. 본 증례는 원위부 림프절 전이가 있어서 수술적 절제가 불가능한 담낭암 환자에서 gemcitabine과 cisplatin을 병합한 전신항암화학요법으로 여섯 주기 치료 후 부분 관해를 얻어서 확대 담낭절제술이 가능하였던 증례로 매우 드문 증례를 경험하였기에 보고하는 바이다. 담낭암에서 수술 전 항암화학요법의 효과는 아직까지 확립되어 있지 않으나, 최근 양호한 종양 반응률과 종양 억제율을 보이는 항암화학요법이 개발됨에 따라서 그 가능성이 기대되고 있다.

  • Backgrounds/Aims: The aim of this study was to evaluate longitudinal changes of post-liver transplantation (LT) biliary anatomy and to assess the association of increased laboratory values after LT with the development of post-LT anastomotic biliary stricture (ABS). Methods: Adult deceased donor LT recipients from 2008 and 2019 were evaluated. ABS was defined after blinded review of endoscopic cholangiograms. Controls were patients who underwent LT for hepatocellular carcinoma who did not have any clinical or biochemical concerns for ABS. Results: Of 534 patients who underwent LT, 57 patients had ABS and 57 patients served as controls. On MRI, ABS patients had a narrower anastomosis (2.47 ± 1.32 mm vs. 3.38 ± 1.05 mm; p < 0.01) and wider bile duct at 1-cm proximal to the anastomosis (6.73 ± 2.45 mm vs. 5.66 ± 1.95 mm; p = 0.01) than controls. Association between labs at day 7 and ABS formation was as follows: aspartate aminotransferase hazard ratio (HR): 1.014; 95% confidence interval (CI): 1.008-1.020, p = 0.001; total bilirubin HR: 1.292, 95% CI: 1.100-1.517, p = 0.002; and conjugated bilirubin HR: 1.467, 95% CI: 1.216-1.768, p = 0.001. Corresponding analysis results for day 28 were alanine aminotransferase HR: 1.004, 95% CI: 1.002-1.006, p = 0.001; alkaline phosphatase HR: 1.005, 95% CI: 1.003-1.007, p = 0.001; total bilirubin HR: 1.233, 95% CI: 1.110-1.369, p = 0.001; and conjugated bilirubin HR: 1.272, 95% CI: 1.126-1.437, p = 0.001. Conclusions: Elevation of laboratory values early after LT is associated with ABS formation.

  • Backgrounds/Aims: Pancreatoduodenectomy (PD) is recommended in fit patients with a carcinoma (PDAC) of the pancreatic head, and a delayed resection may affect survival. This study aimed to correlate the time from staging to PD with long-term survival, and study the impact of preoperative investigations (if any) on the timing of surgery. Methods: Data were extracted from the Recurrence After Whipple's (RAW) study, a multicentre retrospective study of PD outcomes. Only PDAC patients who underwent an upfront resection were included. Patients who received neoadjuvant chemo-/radiotherapy were excluded. Group A (PD within 28 days of most recent preoperative computed tomography [CT]) was compared to group B (> 28 days). Results: A total of 595 patents were included. Compared to group A (median CT-PD time: 12.5 days, interquartile range: 6-21), group B (49 days, 39-64.5) had similar one-year survival (73% vs. 75%, p = 0.6), five-year survival (23% vs. 21%, p = 0.6) and median time-to-death (17 vs. 18 months, p = 0.8). Staging laparoscopy (43 vs. 29.5 days, p = 0.009) and preoperative biliary stenting (39 vs. 20 days, p < 0.001) were associated with a delay to PD, but magnetic resonance imaging (32 vs. 32 days, p = 0.5), positron emission tomography (40 vs. 31 days, p > 0.99) and endoscopic ultrasonography (28 vs. 32 days, p > 0.99) were not. Conclusions: Although a treatment delay may give rise to patient anxiety, our findings would suggest this does not correlate with worse survival. A delay may be necessary to obtain further information and minimize the number of PD patients diagnosed with early disease recurrence.
