[PMID: 38582706 DOI: 10.1016/j.jpedsurg.2024.03.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 03/12/2024] [Accepted: 03/13/2024] [Indexed: 04/08/2024]
Abstract
INTRODUCTION An increasing proportion of congenital choledochal malformation (CCM) are being detected on antenatal ultrasound. However, the actual timing of its surgical correction remains controversial with some series showing an excess of complications the earlier the operation. The aim of this study was to characterize the pathophysiological aspects of this cohort from the perspective of age at surgery in order to inform a more rational basis for clinical decision-making. METHODS We analysed a prospective database of CCM acquired over a 26-year period (Jan. 1997 to Dec. 2022) for patient demography; details of pre- and post-natal imaging; age at surgical intervention; operative complications (Clavien-Dindo classification) and outcome. Data are quoted as median (IQR). All comparisons are non-parametric. A P value of 0.05 was accepted as significant. RESULTS There were 58 (72% female) children with an antenatally-detected CCM from a total of 265 (21.8%) in the series. These were classified as Type 1C (n = 47; 81%), type 4C (n = 3; 5%) and Type 5 (n = 8; 14%). There were no Type 1F lesions in this cohort. Median age at surgery was 113 (IQR 57-198) days. Postnatal cyst (US) size varied from 12 to 130 mm but there was little evidence of a relationship between this and post-natal liver biochemistry (e.g. bilirubin rS = 0.01, P = 0.44; AST rS = 0.14, P = 0.19). Choledochal pressure measurements (n = 46) showed resting pressures of 12 (9-21) mmHg with no significant correlation with age (P = 0.4) or aspartate aminotransferase (P = 0.2) or γ-glutamyl transferase (P = 0.06). The cohort was divided into 2 groups (Early and Late) based on the median age at surgery (all open) (113 days). Biliary obstruction was more common in the Early group (10 vs. 2; P = 0.01). Two perforations occurred, both in the Early group. With a deliberate policy of regular ultrasound-based follow-up we have seen no anastomotic complications (leak, stenosis, persistent intrahepatic biliary dilatation or stones) or post-operative cholangitis in any child [median follow-up 3.42 (1.30-8.05) years]. CONCLUSIONS This is one of the largest series documenting the outcomes of antenatally-detected CCMs, certainly in Europe and North America. Such lesions are invariably cystic in nature, and either Types 1C, 4C or 5. The absence of complications using a policy of early intervention (where possible) in experienced hepatobiliary units was shown. EVIDENCE LEVEL II.

Front Pediatr 2024; 12:1372514. [PMID: 39170601 PMCID: PMC11337223 DOI: 10.3389/fped.2024.1372514] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Accepted: 04/08/2024] [Indexed: 08/23/2024] Open
Abstract
Objective The aim of the study was to develop a prediction nomogram based on clinical factors to assess the risk of postoperative complications in children with congenital choledochal cyst. Methods The clinical data from 131 children who underwent choledochal cyst resection and Roux-en-Y hepaticojejunostomy in our hospital between January 2016 and December 2022 were retrospectively analyzed. The general information, clinical symptoms, procedure, biochemical indicators, and imaging data were recorded. A prolonged hospital stay induced by postoperative complications or a follow-up over 6 months was assessed as the event outcome. A logistics regression analysis was performed to screen for risk factors with statistical significance in inducing postoperative complications. Then, with the dataset split into the training group and internal validation group, the nomogram for the prediction of postoperative complications was developed based on a computer algorithm. In addition, the receiver operating characteristic (ROC) curve and calibration curve were performed for nomogram verification. Results Of 131 children, the multivariate logistics regression analysis suggested that age ≤2 years [odds ratio (OR) 0.93; 95% confidence interval (CI) 0.15-5.65; p = 0.938], Todani classification type 1 (OR 36.58; 95% CI 4.14-871.74; p = 0.005), cyst wall thickness >0.4 cm (OR 10.82; 95% CI 2.88-49.13; p < 0.001), with chronic cholecystitis (OR 7.01; 95% CI 1.62-38.52; p = 0.014), and choledochal cyst diameter (OR 1.01; 95% CI 0.99-1.03; p = 0.370) were predictors associated with the postoperative complications of choledochal cysts. The data were randomly divided into the training group (n = 92) and internal validation group (n = 39) to build the prediction nomogram including the appeal factors. The accuracy and discrimination of the model were evaluated using a ROC curve and calibration curve. The results showed that the nomogram area under the ROC curve [area under the curve (AUC) = 0.894; 95% CI 0.822-0.966; p < 0.001], validation (AUC = 0.844; 95% CI 0.804-0.952; p < 0.001), and Brier = 0.120 (95% CI 0.077-0.163p; p < 0.001) were indicative of the good stability and calibration of the predictive nomogram. Conclusion The prognosis of congenital choledochal cysts was associated with multiple aspects of clinical factors. Combined with the internal validation, the novel prediction nomogram was suitable for evaluating the individualized risk of postoperative complications of choledochal cysts. The prediction nomogram could provide a more accurate strategy of procedure and postoperative follow-up for children with choledochal cysts.

Abstract
The choledochal cyst (CC) can be better termed as biliary tract malformation because of the close association of embryology and etiology in the causation of CC. Contrary to Babbitt's postulation of reflux, damage and dilatation, reflux was not demonstrable as the causative factor in all varieties of CC. High pressure in the biliary system, otherwise termed ductal hypertension, is put forth as an alternative to explain the evolution of CC. The forme fruste type, which does not find a place in the standard classification, typifies the ductal hypertension hypothesis. Hence a closer, in-depth review would be able to highlight this apt terminology of biliary tract malformation.

Abstract
AIM OF THE STUDY The aim of the study is to clarify the clinicopathological and biliary morphological characteristics in reported cases of diverticular congenital biliary dilatation (CBD). METHOD Using PubMed and the Japan Medical Abstracts Society, articles on possible diverticular CBD were extracted and the clinical pictures examined. We also sought evidence for definitions of diverticular CBD and the associated condition of pancreaticobiliary maljunction (PBM) using the original articles by Alonso-Lej and Todani. The characteristic biliary morphologies of cases with images were also investigated. RESULTS Analyses of 211 possible cases superficially demonstrated multiple diverticula in 12 (12%) and single diverticulum in 89 (88%), with diverticula located in the upper (n = 38, 38%), middle (n = 32, 32%), or lower (n = 26, 26%) biliary tract in and presence of intra-diverticular stones, PBM, and biliary carcinoma in 23% (n = 18), 39% (n = 25), and 11% (n = 14), respectively. However, evidence defining diverticular CBD or justifying the lack of associated PBM was not demonstrated even in the original articles. Scrutiny of the biliary anatomy in 59 cases with images showed incorrect inclusions of types I or IV-A with an irregular biliary duct wall or dilated cystic duct, periampullary choledochal diverticula, or even solitary biliary cysts. Authentic diverticular CBD, representing the diverticulum connected to the middle of the common bile duct via a thin, patent stalk was seen in only 6 cases. CONCLUSION Real diverticular CBD appears extremely rare. The lack of an objective definition allows wide interpretations of clinical pictures, creating inconsistencies in the diagnosis and treatment of CBD and raising questions regarding the utility of conventional classifications. LEVEL OF EVIDENCE Level III.

Abstract
Purpose Choledochal cysts are congenital anomalies that occur as localized cystic or fusiform dilatations of the biliary tree. Reflux and stasis of pancreatic enzymes in the biliary duct may relate to the development of intestinal metaplasia which might be an important factor related to the carcinogenesis of choledochal cyst, thus the expression of beta-catenin in the metaplastic epithelium might be associated with malignant transformation of choledochal cyst epithelium. Methods This study was conducted at a tertiary care pediatric center between October 2014 and March 2017. Forty patients were evaluated for epithelial lining, mural ulceration, fibrosis, inflammation, and metaplasia. Results Out of 40, 12 cases (30.0%) were the infantile age group and 28 cases (70.0%) were in the classic pediatric group. Ulceration was classified as grade 0 (14 cases, 35.0%), grade 1 (17 cases, 42.5%), or grade 2 (nine cases, 22.5%). Inflammation was classified as grade 0 (2 cases, 5.0%), grade 1 (26 cases, 65.0%), or grade 2 (12 cases, 30.0%). Fibrosis was classified as grade 0 (five cases, 12.5%), grade 1 (11 cases, 27.5%), grade 2 (17 cases, 42.5%), or grade 3 (seven cases, 17.5%). Metaplasia was noted in five (12.5%) out of 40 cases. All choledochal cysts with metaplasia showed beta-catenin nuclear positivity on immunohistochemistry and were followed up. Conclusion This study emphasizes the importance of detailed histopathological examination and documentation of metaplastic changes. Metaplasia was associated with beta-catenin nuclear positivity. These findings suggest a potential role for beta-catenin as a marker of metaplastic changes in choledochal cysts.

Abstract
BACKGROUND Choledochal cysts (CCs) are rare cystic dilatations of the intrahepatic and/or extrahepatic bile ducts. We review the pathophysiology, diagnosis, and management of CCs. METHODS MEDLINE/PubMed and Web of Science databases were queried for "choledochal cyst", "bile duct cyst", "choledochocele", and "Caroli disease". Data were synthesized and systematically reviewed. RESULTS Classified according to the Todani Classification, CCs are generally believed to arise secondary to reflux of pancreatic enzymes into the biliary tree due to anomalous pancreaticobiliary duct union. Complications of CCs include abdominal pain, jaundice, cystolithiasis, cholecystitis, pancreatitis, liver abscess, liver cirrhosis and malignant transformation (3-7.5%). Radiological and endoscopic imaging is the cornerstone of CC diagnosis and full delineation of cyst anatomy is imperative for proper management. Management is generally guided by cyst classification with complete cyst excision necessary for CCs with high potential of malignant transformation such as types I and IV. 5-year overall survival after choledochal cyst excision is 95.5%. CONCLUSION Most CCs should undergo surgical intervention to mitigate the risk of cyst related complications such as cholangitis and malignant transformation.

Abstract
The two main biliary pathologies in paediatric practice, biliary atresia and choledochal malformations (CM), have their origins within prenatal life. Nevertheless, the actual mechanisms remain elusive with many unanswered questions. The extrahepatic bile duct develops as a funnel-like structure emerging from the foregut from about 3-4 weeks of gestation into the mesenchyme of the septum transversum. The cranial elements of this contain hepatoblasts - the precursors to the two key cell lines that will become hepatocytes and biliary epithelial cells. The intrahepatic bile ducts develop separately and emerge from a complex process involving the ductal plate surrounding the in-growing portal venous system from about the 7-8th week of gestation. A developmental defect at some point(s) in this process may be the cause of at least some variants of BA - the Biliary Atresia Splenic Malformation syndrome particularly - though evidence in the more common isolated BA is much more circumstantial. Similarly, some types of choledochal malformation, specifically the cystic type of CM, are invariably present during prenatal life although again an actual aetiological mechanism remains elusive.

Abstract
Pancreaticobiliary maljunction (PBM) is a congenital anomaly that is defined as a junction of the pancreatic and bile ducts located outside the duodenal wall during the embryonic stage, resulting in bile and pancreatic juice reflux and corresponding clinical symptoms. PBM is a high risk factor for cholangiocarcinoma. PBM can occur with or without biliary dilatation (BD). Early diagnosis of PBM can prevent complications. Ultrasonography, magnetic resonance imaging, multi-slice spiral computed tomography, endoscopic ultrasonography, endoscopic retrograde cholangiopancreatography, and cholangiopancreatography are important modalities for diagnosis of this disease. The standard surgical procedure for PBM with BD is dilated cholangiectomy and choledochoenteroreconstruction. Cholecystectomy should be performed as early as possible for PBM without BD.

Abstract
Choledochal cyst (CC) is a disease with a strong Asian preponderance. As laparoscopic surgery has become mainstay in its treatment, the experience in these countries has been phenomenal. However, there are many contentious issues related with the laparoscopic management of CC. In this review article, we will try to answer the contentious questions related to the laparoscopic management of CC. The issues related to aetiology, classification, surgical technique, type of biliary anastomosis, intrahepatic stones and malignancy are discussed. We also discuss the current and future considerations of laparoscopic management with reference to it becoming a gold standard. This article describes the standard surgical approach and will discuss its technical nuances. This article will also discuss the outcome of treatment in different settings of low- and middle-income countries based on lessons learnt by the authors from their experience and research.

Abstract
INTRODUCTION Type 4 choledochal malformations (CMs) can be defined as extra- and intrahepatic biliary dilatation. They are of uncertain etiology but make up about 20% of most series. The aim of this study was to investigate the pathophysiology and their natural history following surgical intervention. METHODS Ambispective review of a single-center series of type 4 CM between 1996 and 2017. Perioperative imaging, intraoperative pressure monitoring, bile amylase, and long-term follow-up data were analyzed based on extrahepatic morphology [(cystic (C), fusiform (F)]. Data were expressed as median (range). Statistical analysis was performed with nonparametric tests. P < 0.05 was considered significant. RESULTS 37 children had type 4 CM in the study period [age at surgery 4 (0.2-16) years] and could be further subdivided into cystic (4C) (n = 22) or fusiform (4F) (n = 15). There was significantly greater dilatation of the extrahepatic component in the cystic group [30 (11-94) versus 15 (8-90) mm; P = 0.0002] though there was no difference in left duct diameter [cystic 7.5 (0-17) mm versus fusiform 7.5 (3-16) mm; P = 0.86]. There was a trend to higher choledochal pressure in the cystic group [19 (4-40) versus 9 (6-25) mmHg; P = 0.09] and those in the fusiform group had higher bile amylase [8650 (3-890,000) versus 592 (1-123,000) IU/L; P = 0.01] and were older [4.1 (0.92-16.43) versus 2.4 (0.15-15.48) years; P = 0.03]. Children with type 4 CM were then separated simply on the basis of bile amylase into LOW (characterized by high pressure, cystic morphology and young age at surgery) and HIGH bile amylase (low pressure, fusiform morphology and older at time of surgery). CONCLUSIONS We propose further division of type 4 CM into 4C and 4F on clinical and pathophysiological grounds. LEVEL OF EVIDENCE II (prospective cohort).

Abstract
Introduction
Congenital choledochal malformations (CCMs) are characterized by intra- and/or extrahepatic bile duct dilatation. Five basic types (1–5) are recognized in Todani's classification and its modifications, of which types 1 and 4 typically have an associated anomalous pancreatobiliary junction and common channel (CC). We describe two cases with previously undescribed features.
Case Report
1 Antenatal detection of a cyst at porta hepatis was made in an otherwise normal girl of Iranian parentage. She was confirmed to be a CCM (20 mm diameter), postnatally, with no evidence of obstruction. Surgical exploration was performed at 12 weeks. She had an isolated cystic dilatation of the right-hepatic duct only. The left-hepatic duct and common bile duct (CBD) were normal without a CC. Histology of the resected specimen showed stratified squamous epithelium.
Case Report 2
A preterm (31 weeks of gestation) boy of Nigerian parentage was presented. His mother was HIV + ve and he was treated with nucleoside reverse transcriptase inhibitors following birth. He had persistent cholestatic jaundice and a dilated (10 mm) bile duct from birth. Although the jaundice resolved, the dilatation persisted and increased, coming to surgery aged 2.5 years. This showed cystic dilatation confined to the common hepatic duct, and otherwise normal distal common bile duct and no CC.
Result
Both underwent resection with the Roux-en-Y hepaticojejunostomy reconstruction to the transected right-hepatic duct alone in case 1, leaving the preserved left duct and CBD in continuity, and to the transected common hepatic duct in case 2.
Conclusions
Neither choledochal anomaly fitted into the usual choledochal classification and case 1 appears unique in the literature.

Abstract
PURPOSE Our aim was the longitudinal assessment of cyst size in fetuses with biliary cystic malformation (BCM) to explore its etiology and the possibility of antenatal differentiation between biliary atresia (BA) and congenital biliary dilatation (CBD). METHODS We conducted a retrospective review of all patients diagnosed antenatally with BCM from 1994 to 2014 at our institutions. RESULTS The study cohort comprised of three patients with BA and six with CBD. There were no significant differences in the gestational age and cyst size at the first detection of BCM between the two groups. In fetuses with CBD, the cyst size steadily increased as the gestational age advanced, while it fluctuated around 1.5 cm and remained below 2.1 cm in those with BA. However, the ratio of cystic area to fetal trunk area was approximately constant due to linear fetal growth in fetuses with CBD. CONCLUSION Fetuses with BCM <2.1 cm in the late gestation period were more likely to have BA than CBD. Our observation of cyst enlargement with advancing gestational age in the CBD group was attributed solely to fetal growth. Biliary dilatation in fetuses with CBD and BA might be completed at the onset of BCM.

Abstract
Introduction Choledochal cyst (CC) is a morphological malformation characterized by dilatations of the biliary tree that might present later with clinical symptoms, including jaundice, abdominal pain or pancreatitis. Presentation of case Here, we reported a 10-month-old female infant with CC presenting with jaundice and a right upper quadrant mass and who was malnourished following a surgical excision of retroperitoneal teratoma one month ago. Laboratory findings were total bilirubin of 14.17 mg/dL, direct bilirubin of 12.24 mg/dL, gamma glutamyl transferase of 1157 U/L, and alkaline phosphatase 187 U/L. Abdominal computed tomography scan showed a CC that caused dilatation of the proximal common bile duct (CBD), common hepatic duct, and intrahepatic bile duct. We decided to perform an explorative laparotomy and found a CC with diameter of 5 cm. Then, we conducted a Roux-en-Y hepaticojejunostomy. Due to hepaticojejunostomy anastomosis leakage, relaparotomies were done. The patient was uneventfully discharged 17 days after the third surgery. Discussion Our findings are unique because the patient had a normal biliary tree previously and underwent intraabdominal tumor surgery. Notably, besides being an acquired CC, our case might be due to inadvertent bile duct ligation during the first operation or bile duct obstruction as a complication of the first operation. Conclusions CC should be considered as a potential complication of intraabdominal tumor excision, especially if its location is near the CBD. Roux-en-Y hepaticojejunostomy is still the best choice for CC management. The development of acquired choledcohal cyst (CC) might be due to disruption of the biliary tree especially the common bile duct during the excision of intraabdominal tumor. Abdominal computed tomography scan is useful and highly accurate to diagnose of CC. Roux-en-Y hepaticojejunostomy is still the best choice for CC management.

Abstract
Choledochal malformations (CMs) represent a spectrum of relatively rare and complex congenital anomalies, characterized by abnormal dilatation of the biliary tract in the absence of any acute obstruction. Today, almost 20% of CMs can be detected in-utero using maternal ultrasonography. Formal scientometric analysis was used to identify where modern CM research is taking place and perhaps where our attention should be directed in the future. Thus, this article offers a comprehensive review of recent scientific advances relating to CMs including the current understanding of etiology and classification, whilst also discussing key controversies such as risk of malignant transformation and the role of newer modalities of surgical treatment. Although laparoscopic excision of CMs and biliary reconstruction is nowadays feasible and safe, care should be taken before dispensing with standard open techniques, which have minimal complication rates and proven long-term benefit.

Abstract
Pancreaticobiliary maljunction is a congenital malformation in which the pancreatic and bile ducts join outside the duodenal wall, usually forming a long common channel. Because the action of the sphincter of Oddi does not regulate the function of the pancreaticobiliary junction in patients with pancreaticobiliary maljunction, two-way regurgitation occurs. Reflux of pancreatic juice into the biliary tract is associated with a high incidence of biliary cancer. Biliary carcinogenesis in patients with pancreaticobiliary maljunction is thought to follow the hyperplasia, dysplasia, then carcinoma sequence due to chronic inflammation caused by pancreatobiliary reflux. Pancreaticobiliary maljunction is diagnosed when an abnormally long common channel is evident on imaging studies. Congenital biliary dilatation involves both local dilatation of the extrahepatic bile duct, including the common bile duct, and pancreaticobiliary maljunction. Extrahepatic bile duct resection is the standard surgery for congenital biliary dilatation. However, complete excision of the intrapancreatic bile duct and removal of stenoses of the hepatic ducts are necessary to prevent serious complications after surgery.

Abstract
BACKGROUND Choledochal malformations comprise various congenital cystic dilatations of the extrahepatic and/or intrahepatic biliary tree. Choledochal malformation is generally considered a premalignant condition, but reliable data on the risk of malignancy and optimal surgical treatment are lacking. The objective of this systematic review was to assess the prevalence of malignancy in patients with choledochal malformation and to differentiate between subtypes. In addition, the risk of malignancy following cystic drainage versus complete cyst excision was assessed. METHODS A systematic review of PubMed and Embase databases was performed in accordance with the PRISMA statement. A meta-analysis of the risk of malignancy following cystic drainage versus complete cyst excision was undertaken in line with MOOSE guidelines. Prevalence of malignancy was defined as the rate of biliary cancer before resection, and malignant transformation as new-onset biliary cancer after surgery. RESULTS Eighteen observational studies were included, reporting a total of 2904 patients with a median age of 36 years. Of these, 312 in total developed a malignancy (10·7 per cent); the prevalence of malignancy was 7·3 per cent and the rate of malignant transformation was 3·4 per cent. Patients with types I and IV choledochal malformation had an increased risk of malignancy (P = 0·016). Patients who underwent cystic drainage had an increased risk of developing biliary malignancy compared with those who had complete cyst excision, with an odds ratio of 3·97 (95 per cent c.i. 2·40 to 6·55). CONCLUSION The risk of developing malignancy among patients with choledochal malformation was almost 11 per cent. The malignancy risk following cystic drainage surgery was four times higher than that after complete cyst excision. Complete surgical resection is recommended in patients with choledochal malformation.

Abstract
Intraluminal pressure elevation can cause degenerative disorders, such as ileus and hydronephrosis, and the threshold is fairly low and constant, 20–30 cm H2O. We previously devised a novel two-chamber culture system subjecting cells cultured on a semipermeable membrane to increased culture medium height (water pressure up to 60 cm H2O). Here, we sought to determine how a continuous pressure load of ~30 cm H2O affects proliferating epithelial cells with special interest in the link with cell morphology. We cultured several different cell lines using the low static pressure-loadable two-chamber system, and examined cell growth, cell cycle, and cell morphology. Madin–Darby canine kidney (MDCK) columnar epithelial cells were growth-suppressed in a manner dependent on static water pressure ranging from 2 to 50 cm H2O, without cell cycle arrest at any specific phase. Two other types of columnar epithelial cells exhibited similar phenotypes. By contrast, spherical epithelial and mesenchymal cells were not growth-suppressed, even at 50 cm H2O. Phalloidin staining revealed that 50 cm H2O pressure load vertically flattened and laterally widened columnar epithelial cells and made actin fiber distribution sparse, without affecting total phalloidin intensity per cell. When the mucosal protectant irsogladine maleate (100 nM) was added to 50-cm-high culture medium, MDCK cells were reduced in volume and their doubling time shortened. Cell proliferation and morphology are known to be regulated by the Hippo signaling pathway. A pressure load of 50 cm H2O enhanced serine-127 phosphorylation and cytoplasmic retention of YAP, the major constituent of this pathway, suggesting that Hippo pathway was involved in the pressure-induced cell growth suppression. RNA sequencing of MDCK cells showed that a 50 cm H2O pressure load upregulated keratin 14, an intermediate filament, 12-fold. This upregulation was confirmed at the protein level by immunofluorescence, suggesting a role in cytoskeletal reinforcement. These results provide evidence that cell morphology and the cytoskeleton are closely linked to cell growth. Pathological intraluminal pressure elevation may cause mucosal degeneration by acting directly on this linkage and the Hippo pathway.

Abstract
Infantile Choledochal Cysts (IFCC) usually present with jaundice, acholic stool and abdominal lump or abdominal distension. If the surgical intervention is delayed, they rapidly progress to liver fibrosis which is considered to be irreversible if progressed to cirrhosis. We present the data of four cases (aged one month to seven months) of IFCC presented with cholangitis managed in one surgical unit in last two years. In one case, cholangitis was treated with prolonged antibiotic course before definitive repair whereas in rest, external drainage of cyst was done in addition to intravenous antibiotic to treat cholangitis. All the infants had features of cholangitis at time of presentation. Total leucocyte count ranged from 18x1000/UL to 30.6x1000/UL. Total bilirubin level at presentation ranged from 8.2 mg/dl to 18 mg/dl and Prothrombin time (INR) ranged from 1.33 to 1.9. Hepatic fibrosis was observed in all cases but cirrhosis was observed in only one case. There was no mortality but one patient had postoperative complication with prolonged hospital stay. External drainage helps in early recovery from cholangitis and better optimization of liver function. It also delays further progression to liver fibrosis by relieving the biliary outflow obstruction while waiting for definitive repair.

Abstract
PURPOSE There is a predisposition to the development of malignancy in congenital choledochal malformation (CCM) although the degree of risk is unknown. We investigated the role of CA19-9 in bile and the MIB-1 (Ki-67) epithelial proliferation index as markers of an at risk choledochal epithelium at the time of definitive surgery. METHODS Bile collected at surgery was analyzed for levels of amylase (as a surrogate of pancreatic reflux) and CA19-9. Immunohistochemical staining for CA19-9 and MIB-1 index (expressed as %) was performed on resected specimens. Data are quoted as median (IQR) and differences assessed using non-parametric statistics. A P value of 0.05 was regarded as significant. RESULTS Our study group consisted of 78 children with CCM (Type 1 fusiform, n=34; Type 1 cystic, n=30 and Type 4, n=14). Median bile CA19-9 was 159,400 (6-1×10(6)) kU/L. There was no correlation with bile amylase (P=0.49) or biliary pressure (P=0.17) but modest correlation with bilirubin (rs=0.24; P=0.02). In contrast, bile amylase was correlated with plasma γ-glutamyl transpeptidase (P=0.02), alkaline phosphatase (P=0.05) and aspartate aminotransferase (P=0.02); and inversely correlated with biliary pressure (rs=-0.38; P<0.0008). Epithelial expression of CA19-9 and MIB-1 was assessed in 43 specimens. CA19-9 was diffusely expressed on all choledochal epithelium. MIB-1 expression was divided into: high expression (>40%) n=3; moderate (20-40%) n=5, low (6-20%) n=7 and very low (≤5%) n=28. There was no correlation with choledochal pressure (P=0.87), CA19-9 (P=0.51) or bile amylase (P=0.55). CONCLUSION Biliary CA19-9 levels were grossly (and unexpectedly) raised in choledochal malformation and appear to arise from biliary rather than pancreatic epithelium. MIB-1 confirms that a small proportion (19%) has marked epithelial proliferation but no clinical correlates could be identified.

Abstract
PURPOSE Excision and biliary reconstruction using a Roux loop is the current standard for choledochal malformation (CM). This is un-physiological, delivering bile beyond the duodenum and excluding a significant length of the jejunum from intestinal absorption. We investigated whether this had an effect on post-operative growth. METHODS Retrospective case-note analysis of children surgically treated for CM. Growth variables were converted to standard deviation scores (SDS) and compared against population norms. P < 0.05 was significant. RESULTS From 1994 to 2014, 135 children (<16 years) were identified. Median age at surgery was 3.3 (IQR 1.5-7) years. Morphology included: type 1 Cystic (n = 54, 40%), type 1 Fusiform (n = 58, 43%) and type 4 (intra and extra-hepatic) (n = 22, 16%). There was pre-operative growth failure [median weight SDS = -0.4 (-1.2 - 0.4), P = 0.0004] with a similar trend for height [SDS = -0.38 (-1.2 - 0.5), P = 0.08)]. This correlated with presentation bilirubin (r s = -0.24, P = 0.004), GGT (r s = -0.27, P = 0.002) and AST (r s = -0.27, P = 0.002) but not morphology (P = 0.82) or presentation (P = 0.4). Median follow-up was 1.9 (0.6-4.7) years, during which time both height (P = 0.73) and weight (P = 0.45) reverted to normal. CONCLUSION This is the first report of growth in children with CM following a Roux-loop reconstruction and showed pre-operative growth failure probably attributed to a period of biliary obstruction but catch-up growth when corrected.

Choledochal Cyst in Adults: Etiopathogenesis, Presentation, Management, and Outcome-Case Series and Review. Gastroenterol Res Pract 2015; 2015:602591. [PMID: 26257778 PMCID: PMC4518150 DOI: 10.1155/2015/602591] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2015] [Revised: 06/14/2015] [Accepted: 06/16/2015] [Indexed: 02/07/2023] Open
Abstract
Background. Choledochal cyst, a rare congenital cystic dilatation of biliary tree, is uncommon in adults. Their presentations differ from children and surgical management has evolved. Methods. A retrospective review of the records of all the patients above 15 years, who underwent therapeutic intervention in our hospital, was carried out. Results. Ten cases of choledochal cyst were found; 8 female, with mean age 31 years. These included 8 cases of Todani type I and one case each of type II and type III. The predominant symptoms were abdominal pain and jaundice. Abdominal mass and past history of cholangitis and pancreatitis were seen in 2 patients. Investigations included ultrasound in 8 patients, CT in 7, ERCP in 3, and MRCP in 5. Surgical intervention included complete excision of the cyst with hepaticojejunostomy and cholecystectomy (type I), excision of the diverticulum (type II), and ERCP sphincterotomy (type III). Malignancy was not seen in any patients. The long-term postoperative complications included cholangitis in two patients. Conclusion. Choledochal cyst is rare in adults. The typical triad of abdominal pain, jaundice, and mass is uncommon in adults. The surgical strategy aims for single stage complete excision of the cyst with hepaticojejunostomy.

Correlation of intracystic pressure with cyst volume, length of common channel, biochemical changes in bile and histopathological changes in liver in choledochal cyst. J Indian Assoc Pediatr Surg 2014; 19:10-6. [PMID: 24604978 PMCID: PMC3935293 DOI: 10.4103/0971-9261.125946] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/14/2022] Open
Abstract
AIMS This study was undertaken to establish correlation between intracholedochal cystic pressure (ICCP) with biochemical changes in bile, liver histology, cyst wall histology, length of common channel, and cyst volume. MATERIALS AND METHODS In this cross-sectional study, ICCP was measured after surgical access before any mobilization by direct cyst cannulation. Bile was then aspirated for biochemical estimation (bilirubin, amylase, lipase, pH, and electrolytes). Common channel length and cyst volume were determined by preoperative magnetic resonance cholangiopancreatography (MRCP). Liver histology was assessed under parenchymal, bile duct, and portal parameters. Cyst wall was examined for ulceration, inflammation, fibrosis, and metaplasia. RESULTS ICCP was recorded in 31 patients; mean and median ICCP were 15.64 and 14 mmHg, respectively (range = 6-30 mmHg). Cases with median ICCP < 14 had median cyst volume of 48 cc (range = 36-115) and amylase 2052 IU/L (range = 190-5052) whereas those with ICCP ≥ 15 had volume of 20 cc (range = 10-100) (P = 0.004) and amylase 36 IU/L (range = 0-2806) (P = 0.0004) suggesting inverse correlation. No significant correlation was found with bilirubin and electrolytes. ICCP directly correlated with parenchymal changes like hepatocellular damage (P = 0.002) and cholestasis (P = 0.001). It also correlated with bile duct changes. ICCP inversely correlated with cyst wall changes (P = 0.003, 0.0001, 0.023, 0.0013, respectively). High pressure cysts had normal pancreaticobiliary junction. CONCLUSION High-pressure cysts tend to be smaller but have more severe backpressure changes in liver parenchyma. Low-pressure cysts have high volume and higher levels of amylase and lipase and therefore have more severe cyst wall changes.
