A therapeutic ERCP in an only 5.9 kg infant with obstruction jaundice using JF-260V duodenoscope.

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) has found extensive use in pediatric patients; however, challenges persist in the application of therapeutic ERCP in infants. CASE PRESENTATION: This case report details the presentation of a 5.9-kilogram infant with obstructive jaundice and suspected hemolytic anemia who underwent ERCP to alleviate biliary obstruction. The infant was admitted due to clay-colored stools, jaundice, and liver injury. Ultrasound and magnetic resonance cholangiopancreatography (MRCP) revealed dilation of the common bile duct (CBD) accompanied by the presence of stones. ERCP was conducted using a JF-260V duodenoscope under general anesthesia. Successful stone extraction and biliary drainage were achieved. CONCLUSIONS: In centers with considerable expertise in ERCP and pediatric anesthesia, the use of a conventional adult duodenoscope for therapeutic ERCP in infants can be considered safe and feasible, provided careful and stringent patient selection criteria are applied. In the future, clear guidelines and standardized protocols for the indications and procedures of pediatric ERCP should be established.

An unusual evolution of thyroid function after therapeutic plasma exchange in Graves' disease with cholestatic jaundice: A case report.

RATIONALE: Methimazole (MMI) is the first-line agent in the treatment of hyperthyroidism. However, rare but severe cholestatic jaundice may occur. Therapeutic plasma exchange (TPE) may provide an alternative treatment for such patients and they received thyroidectomy/radioactive iodine ablation or continued oral anti hyperthyroidism medication immediately after TPE session in the reported literatures. The case reported here is, to our knowledge, the first to describe the long interval between anti hyperthyroidism therapy and TPE in such patients. PATIENT CONCERNS: A 49-year-old Chinese woman had developed worsening jaundice 3 weeks after receiving methimazole (20 mg/day) for the treatment of hyperthyroidism secondary to Graves' disease (GD). Additionally, she had a 2-year history of type 2 diabetes. DIAGNOSIS: Hyperthyroidism secondary to GD, MMI-induced severe cholestatic jaundice and type 2 diabetes. INTERVENTIONS: Methimazole was discontinued and the patient received 3 times of TPE, about 3-month glucocorticoid treatment, insulin administration accordingly and other conventional liver-protecting therapy. OUTCOMES: Her thyroid function was stabilized with small dose of thyroxine substitution and euthyroid status persisted after thyroxine discontinuation until hyperthyroidism recurred 7 months later while her cholestatic jaundice was eventually recovered by about 3-month glucocorticoid therapy. LESSONS: Due to the complex interplay between liver function and thyroid hormones, there may be unusual changes of thyroid function in GD patients with severe liver injury after TPE. By this case, we want to highlight the importance of a closely following up of thyroid function in order to deliver appropriate health suggestions for patients.

Utility of enteral nutrition via percutaneous transhepatic cholangiography drainage catheterization in late-stage malignant obstructive jaundice.

Objective: The purpose of this study was to explore the clinical benefits of establishing an enteral nutrition (EN) pathway via percutaneous transhepatic cholangiography drainage (PTCD) catheterization in patients with late-stage malignant obstructive jaundice (MOJ).Methods: We selected 30 patients diagnosed as having late-stage MOJ with malnutrition. A dual-lumen biliary-enteral nutrition tube was placed via PTCD along with a biliary stent implantation. Postoperative EN was provided, and we observed the time taken for tube placement, its success rate, complications, and therapeutic efficacy.Results: Tube placement was successful in all 30 patients with an average procedural time of 5.7 ± 1.4 min with no tube placement complications. Compared to preoperative measures, there was a significant improvement in postoperative jaundice reduction and nutritional indicators one month after the procedure (p < 0.05). Post-placement complications included tube perileakage in 5 cases, entero-biliary reflux in 4 cases, tube blockage in 6 cases, tube displacement in 4 cases, accidental tube removal in 3 cases, and tube replacement due to degradation in 8 cases, with tube retention time ranging from 42 to 314 days, averaging 124.7 ± 37.5 days. All patients achieved the parameters for effective home-based enteral nutrition with a noticeable improvement in their quality of life.Conclusion: In this study, we found that the technique of establishing an EN pathway via PTCD catheterization was minimally invasive, safe, and effective; the tube was easy to maintain; and patient compliance was high. It is, thus, suitable for long-term tube retention in patients with late-stage MOJ.

[Clinical efficacy of single/double 125I-seed strands combined with biliary stents in the treatment of malignant obstructive jaundice].

Objective: To compare the clinical efficacy of single/double 125I-seed strands combined with biliary stents in the treatment of malignant obstructive jaundice. Methods: Totally 67 cases of patients with malignant obstructive jaundice who received single/double125I-seed strands combined with biliary stents implantation from September 2018 to December 2021 were analyzed retrospectively. Among them, 36 patients received single 125I-seed strands combined with biliary stents (single strand group) and 31 patients received double 125I-seed strands combined with biliary stents(double strands group). The technical success rate, clinical success rate, complications, biochemical and tumor indexes at 8 weeks after operation [total bilirubin (TB), direct bilirubin (DB), alanine transaminase (ALT), aspartate transaminase (AST), carbohydrate antigen 19-9 (CA19-9)], stent patency time (SP), median progression-free survival time (mPFS) and median survival time (mOS) were analyzed. Results: There was no significant difference (P>0.05) in technical success rate (100% vs 100%), clinical success rate (97.2% vs 96.8%) and major complications (5.6% vs 6.5%) between single strand group and double strands group. There were significant differences in TB, DB, ALT, AST and CA19-9 indicators between the two groups before and 8 weeks after operation (all P<0.05), but there was no significant difference in the difference value of preoperative and postoperative 8-week indicators between the two groups (all P>0.05).The SP and mPFS of double-stranded stents were longer than those of single-stranded stents.[8.6 months (95%CI:6.9-10.4) vs 6.2 months (95%CI:5.8-6.6), 3.2 months (95%CI:3.0-3.4) vs 3.0 months (95%CI:2.9-3.1), all P<0.05]. The mOS of single and double strands groups was 11.2 months (95%CI:8.3-14.1) and 13.4 months (95%CI:9.9-16.9) respectively, with no statistical difference (P=0.137). Conclusion: Compared with single 125I-seed strands, double 125I-seed strands can prolong biliary SP and mPFS, but the long-term survival index still needs further observation.

Safety and efficacy of self-expandable metallic stent combined with 125I brachytherapy for the treatment of malignant obstructive jaundice.

BACKGROUND: Several previous studies demonstrated that the combination of self-expandable metallic stents (SEMS) and 125I seed implantation might prolong stent patency and obtain survival benefits for malignant obstructive jaundice (MOJ) patients. However, these studies rarely mentioned a comparison between CT-guided intratumoral 125I seed implantation and intraluminal 125I seed strand insertion combined with stenting for the management of MOJ. This study aimed to further evaluate the safety and efficacy of SEMS combined with 125I brachytherapy in the management of unresectable MOJ. METHODS: Fifty-nine patients with unresectable MOJ were retrospectively included from March 2018 to June 2021. The main therapeutic outcomes were evaluated in terms of stent patency, and overall survival. Cumulative stent patency and overall survival rates were calculated by Kaplan-Meier survival analysis. Both clinical and treatment factors associated with survival were analyzed. RESULTS: Technical success was achieved in all patients. The clinical success rate was 94% (32/34) in the seeds group and 92% (23/25) in the control group, no significant difference was found (p =1.000). The median duration of stent patency was significantly longer in the 125I brachytherapy group compared with the control group (289 days vs. 88 days, respectively, p =0.001). The 125I brachytherapy group demonstrated a significantly better median overall survival rate than the control group (221 days vs. 78 days, respectively, p =0.001). In multivariate analysis, stents with 125I brachytherapy (p =0.004) was a significant favorable prognostic factor that affected patient survival. No significant difference was observed between CT-guided 125I seed implantation and 125I seed strand insertion in stent patency (p =0.268), and overall survival (p =0.483). CONCLUSION: SEMS combined with 125I brachytherapy is safe and effective for treating MOJ. 125I brachytherapy may help to maintain stent patency and prolong overall survival. There was no significant difference between CT-guided 125I seed implantation with SEMS and 125I seed strand insertion with SEMS in stent patency and overall survival.

Effect of Biliary Tract Invasion with Obstructive Jaundice on the Prognosis of Patients With Unresectable Hepatocellular Carcinoma.

RATIONALE AND OBJECTIVES: Biliary tract invasion (BTI) is associated with poor outcomes in patients with hepatocellular carcinoma (HCC). However, the presence of a BTI is a neglected variable for staging in the current guidelines. This study aimed to explore the effects of BTI with obstructive jaundice on the prognosis of patients with unresectable HCC. METHODS: We retrospectively included 205 patients initially diagnosed with unresectable HCC who presented with obstructive jaundice due to BTI between January 2010 and June 2021. BTI was classified into four types according to the location of the biliary obstruction. Both clinical and treatment factors that affect median overall survival (mOS) were analyzed. RESULTS: The mOS of patients with Barcelona Clinic Liver Cancer (BCLC) stages B, C, and D was 9.2 months, 3.4 months, and 1.8 months, respectively (p<.001). The mOS of BTI type I patients was superior to that of BTI type II patients (7.1 months vs. 3.2 months, p=.002). Patients who underwent successful biliary drainage had a longer mOS than those who underwent unsuccessful biliary drainage (10.4 months vs. 2.9 months, p<.001). In the multivariate analysis, BTI type I (p=.009), successful biliary drainage (p=.005), and HCC treatment (p<.001) were significant favorable prognostic factors that affected patient survival. CONCLUSION: HCC patients with BTI type II may have a poorer prognosis than those with BTI type I. Effective biliary drainage and anti-cancer treatment may provide survival benefits to these patients. A more detailed staging system for HCC based on the state of BTI is needed.

Biliary Drainage Reduces Intestinal Barrier Damage in Obstructive Jaundice by Regulating Autophagy.

This study aims to investigate the mechanism by which biliary drainage reduces intestinal barrier damage in obstructive jaundice (OJ). A biliary drainage model was established in rats with OJ to detect changes in inflammatory factors and diamine oxidase (DAO), a marker of intestinal mucosal damage. The expression of autophagy-related genes in the intestinal mucosa after biliary drainage was detected using a reverse transcription-polymerase chain reaction. The rats were separated into two groups that received the autophagy activator rapamycin (RAPA) or the autophagy inhibitor 3-methyladenine (3-MA) to further investigate whether biliary drainage could alleviate the inflammatory response, oxidative stress, mitochondrial complex IV damage, and thus barrier damage in rats with OJ. The expression levels of inflammatory factors and the serum DAO content were increased in rats with OJ (P < 0.05). Biliary drainage further induced autophagy, reduced the expression levels of inflammatory factors, decreased the serum DAO content (P < 0.05), and improved intestinal mucosal damage. Administration of RAPA to OJ rats with biliary drainage increased autophagy (P < 0.05); decreased inflammatory factor secretion (P < 0.05), the serum DAO content (P < 0.05), oxidative stress (P < 0.05), and mitochondrial respiratory chain complex IV damage (P < 0.05); and ameliorated intestinal mucosal injury in OJ rats. When OJ rats were treated with 3-MA, intestinal mucosal injury, intestinal mitochondrial injury, and oxidative stress were all aggravated (P < 0.05). Biliary drainage can reduce the expression of inflammatory factors, oxidative stress, and mitochondrial injury by inducing intestinal mucosal autophagy in OJ rats, thus suggesting its role in the alleviation of intestinal mucosal injury.

Secondary Choledocholithiasis in Obstructive Jaundice Patient due to Choledochoduodenal-fistula Stricture.

Choledochoduodenal fistula (CDF) is a rare condition marked by an abnormal connection between the biliary duct and duodenum. The common etiology of secondary CDF are cholecystolithiasis, tumor, and duodenal ulcer. CDF may also caused by prior inflammatory condition or as a complication of radiation therapy. Management for this case is based on the patient condition. Herein we aimed to present a case of secondary choledocholithiasis due to stricture in the CDF which presented with cholangitis treated by self-expanding metal stent (SEMS) for biliary drainage. Patient admitted with jaundice, fever, right upper quadrant pain, and history of cholecystectomy. Diagnosis of CDF was determined by endoscopic retrograde cholangiopancreatography (ERCP) and followed by putting biliary stent for urgent biliary drainage. The follow up result after stent removal was excellent.

Transarterial chemoembolization for hepatocellular carcinoma with vascular invasion.

Although the global guidelines only recommend systemic therapy for hepatocellular carcinoma with vascular invasion, various treatments are performed for it. Among them, transarterial chemoembolization (TACE) is the most frequent option; however, standard techniques have not been established. Conventional TACE (cTACE) has also been frequently performed for tumors invading the portal vein (PVTT), hepatic vein (HVTT), and bile duct (BDTT). In cTACE for PVTT, selective catheterization into the tumor-feeder is essential to avoid adverse effects. However, if it is unsuccessful, injection of embolic agents under balloon occlusion of the hepatic artery can improve the therapeutic effects and avoid hepatic infarction. When marked arterioportal shunts are demonstrated, embolization with gelatin sponge particles soaked with a chemotherapeutic solution is another option. Arteriovenous shunts accompanied by HVTT may cause systemic embolization due to migration of embolic agents, and occlusion of a shunt-draining hepatic vein using a balloon catheter can reduce the risk. BDTT is often accompanied by obstructive jaundice; therefore, endoscopic or percutaneous biliary drainage is required when the serum total bilirubin concentration is ≥3 mg dl-1. TACE should be performed as selectively as possible and attention should also be paid to the risk of obstructive jaundice and/or pancreatitis caused by sloughing of necrotized BDTT.

Hepatic arterial infusion chemotherapy following simultaneous metallic stent placement and iodine-125 seed strands for advanced cholangiocarcinoma causing malignant obstructive jaundice: a propensity score matching study.

OBJECTIVE: This study aims to evaluate the effectiveness and safety of hepatic arterial infusion chemotherapy (HAIC) following the simultaneous placement of self-expandable metallic stent (SEMS) and iodine-125 (125I) seed strands for the management of advanced cholangiocarcinoma (CCA) patients presenting with malignant obstructive jaundice (MOJ). METHODS: Data from 74 patients with MOJ caused by advanced CCA treated with stent placement with 125I seed strands with or without HAIC between November 2015 and October 2020 were analysed retrospectively. Eighteen patients received 5 sessions of HAIC after SEMS placement with 125I seed strands (HAIC group), and 56 patients only underwent SEMS placement with 125I seed strands and served as controls (control group). HAIC consisted of infusions of gemcitabine (600-1000 mg/m2 given over 30 min) followed by oxaliplatin (60-100 mg/m2 given over 2 h), with an interval of 4 weeks. Propensity score matching (PSM) analysis was used to adjust for differences in the baseline characteristics of the groups (including age, total bilirubin, and serum alanine aminotransferase level). Overall survival (OS), stent patency, and adverse events were compared between the two groups. RESULTS: OS and stent patency were significantly better in patients in the HAIC group than in those in the control group (median survival time: before PSM, 362 vs. 185 days, p = 0.005; after PSM, 357 vs. 183 days, p = 0.012; median duration of stent patency: before PSM, 294 vs. 156 days, p = 0.001; after PSM, 287 vs. 183 days, p = 0.039). All adverse reactions were controllable by temporary symptomatic treatment. Serious complications and treatment-related deaths were not observed. CONCLUSION: Our preliminary study showed that HAIC following SEMS placement with 125I seed strands is effective and safe for the management of advanced CCA patients presenting with MOJ and could improve stent patency and patient survival.

Disease-Based Risk Stratification of Postendoscopic Retrograde Cholangiopancreatography Pancreatitis for Common Bile Duct Stones.

BACKGROUND: Risk stratification of postendoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) for common bile duct (CBD) stones is needed for clinicians to adequately explain to patients regarding the risk of PEP in advance of ERCP and to proactively take preventive measures in high-risk patients. AIMS: To stratify the risk of PEP for CBD stones based on CBD-related diseases. METHODS: A total of 1551 patients with naïve papilla who underwent ERCP for CBD stones were divided into three groups: Group A: asymptomatic CBD stones, Group B: obstructive jaundice and elevated liver test values without cholangitis, and Group C: mild, moderate, and severe cholangitis. We stratified the risk of PEP by comparing its incidence among the three groups using the Holm's method. Furthermore, we performed one-to-one propensity score matching between Group A and the other groups to examine the risk of PEP in Group A. RESULTS: The incidence rates in Groups A, B, and C were 13.7%, 7.3%, and 1.8%, respectively. The Holm-adjusted p values between Groups A and B, Groups A and C, and Groups B and C were 0.023, < 0.001, and < 0.001, respectively. Propensity score matching revealed that the incidence of PEP was significantly more in Group A than in the other groups (13.3% vs. 1.5%; p < 0.001). CONCLUSIONS: The risk of PEP for CBD stones was stratified into low risk (Group C), intermediate risk (Group B), and high risk (Group A). This simple disease-based risk stratification may be useful to predict the risk of PEP in advance of ERCP.

Trial protocol: a randomised controlled trial to verify the non-inferiority of a partially covered self-expandable metal stent to an uncovered self-expandable metal stent for biliary drainage during neoadjuvant therapy in patients with pancreatic cancer with obstructive jaundice (PUN-NAC trial).

INTRODUCTION: Neoadjuvant chemotherapy or neoadjuvant chemoradiotherapy (NAC/NACRT) for resectable/borderline resectable pancreatic cancers was recently performed to improve clinical outcomes and led to good results, although it remains controversial whether NAC/NACRT is beneficial for resectable pancreatic cancer. A few recent studies revealed longer patency and lower cost related to the stent occlusion of a metal stent than those of a plastic stent during NAC/NACRT. It also remains controversial which type of self-expandable metal stent (SEMS) is the most suitable for patients with resectable/borderline resectable pancreatic cancer during NAC/NACRT: an uncovered SEMS (USEMS), a fully covered SEMS (FCSEMS) or a partially covered SEMS (PCSEMS). So far, two randomised controlled trials indicated that a USEMS and an FCSEMS were similar in preoperative stent dysfunction and adverse event rate. Thus, we aimed to verify the non-inferiority of a PCSEMS to a USEMS in this multicentre randomised controlled trial. METHODS AND ANALYSIS: We designed a multicentre randomised controlled trial, for which we will recruit 100 patients with resectable/borderline resectable pancreatic cancer and distal biliary obstruction scheduled for NAC/NACRT from 13 high-volume institutions. Patients will be randomly allocated to the PCSEMS group or USEMS group. The primary outcome measure is the preoperative biliary event rate. Data will be analysed after completion of the study. We will calculate the 95% CIs of the incidence of preoperative biliary events in each group and analyse whether the difference between them is within the non-inferiority margin (10%). ETHICS AND DISSEMINATION: This study has been approved by the institutional review board of Hokkaido University Hospital. The results will be submitted for presentation at an international medical conference and published in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: UMIN000041737; jRCT1012200002.

Dynamic change of serum CA19-9 levels in benign and malignant patients with obstructive jaundice after biliary drainage and new correction formulas.

BACKGROUND: CA19-9 is one of the most widely used tumor markers in biliary-pancreatic diseases. The measured value may not factually reflect the genuine CA19-9 level secreted by tumor, which affected by biliary obstruction. There is an urgent need of developing a correction formula of CA19-9 in biliary obstructive patients to guide clinical practice and avoid making improper clinical decision. METHODS: Clinical characteristics were collected among patients undergoing biliary drainage in our hospital between January 2014 and January 2019. By comparing the malignant and benign patients statistically, dynamic change trend of CA19-9 levels after biliary drainage was obtained. The correction formulas of CA19-9 were generated by means of linear regression. RESULTS: 121 patients, including 102 malignant and 19 benign patients, were enrolled in this study. The baseline CA19-9 level of malignant patients is much higher than that of benign patients. Total bilirubin (TB) level was found to be not related with CA19-9 value (p = 0.109). The drop proportion of the average CA19-9 level in the malignant patients (39.2%, IQR -18.4-78.6%) was much lower than that in the benign patients (75.7%, IQR 58.1-86.6%) (p = 0.014). The correction formula, CA19-9True = 0.63 × CA19-9Measured - 20.3 (R2 = 0.693, p<0.001), was generated based on the linear relation between CA19-9 after drainage and CA19-9 before drainage in malignant patients, which had similar diagnostic value with true CA19-9 value. CONCLUSIONS: Quantitative correction formulas of CA19-9 considering the effect of biliary decompression was first proposed in this study, aiming to provide a more accurate CA19-9 level to make more accurate clinical decision and avoid making improper therapeutic schedule.

Hemosuccus Pancreaticus and Obstructive Jaundice: Two Rare Complications of Chronic Pancreatitis Treated by Arterial Embolization.

The formation of a peripancreatic pseudoaneurysm is a rare and serious complication of chronic pancreatitis. In this report, we present the case of a 56-year-old male with a history of alcohol-related chronic pancreatitis resulting in both hemosuccus pancreaticus and obstructive jaundice due to a pseudoaneurysm of the gastroduodenal artery that was treated successfully by angiographic coiling.

Locally advanced pancreatic carcinoma with jaundice: the benefit of a sequential treatment with stenting followed by CT-guided 125I seeds implantation.

OBJECTIVES: To evaluate the role of sequential therapy with percutaneous biliary stenting and CT-guided iodine-125 seed implantation for locally advanced pancreatic carcinoma with concomitant obstructive jaundice. METHODS: Between January 2016 and December 2018, 42 patients diagnosed with locally advanced pancreatic carcinoma with concomitant obstructive jaundice were enrolled retrospectively. All patients received biliary stenting via percutaneous transhepatic biliary drainage (PTBD) to alleviate obstructive jaundice. Thereafter, twenty-two patients underwent CT-guided iodine-125 seed implantation (treatment group), and 20 did not (control group). The prescribed dose in the treatment group was 110-130 Gy. The clinical data, duration of biliary stent patency, and overall survival (OS) were evaluated. RESULTS: Overall, the total bilirubin level decreased from 275.89 ± 115.44 to 43.08 ± 43.35 µmol/L (p < 0.001) 1 month after percutaneous biliary stenting. In the treatment group, the postoperative median dose covering 90% of the target volume was 129.71 Gy. Compared with the control group, the treatment group had a long mean duration of biliary stent patency and median OS (11.42 vs. 8.57 months, p < 0.01; 11.67 vs. 9.40 months, p < 0.01, respectively). The overall positive response rates 6 months post-treatment in the treatment and control groups were 72.7% (16/22) and 30% (6/20), respectively. Adverse events of more than grade 3 were not observed during the follow-up. CONCLUSION: Sequential therapy with percutaneous biliary stenting and CT-guided iodine-125 seed implantation is an effective and safe treatment alternative for locally advanced pancreatic carcinoma with concomitant obstructive jaundice, which is worthy of clinical application. KEY POINTS: • Obstructive jaundice was alleviated after biliary stent placement in all patients, and the total bilirubin level decreased. • The overall positive response rates at 6 months post-treatment were higher in the treatment group than in the control group, and adverse events of more than grade 3 were not observed during the follow-up period. • Sequential therapy with percutaneous biliary stenting and CT-guided iodine-125 seed implantation can prolong biliary stent patency and improve survival.

Case of cholestatic jaundice associated with papillary carcinoma of thyroid: a multidisciplinary challenge.

The report describes a patient with cholestatic jaundice who had incidentally detected parathyroid hormone-independent hypercalcaemia. The differential diagnosis for this presentation includes systemic granulomatous and infiltrative disorders, drug-induced liver injury and malignancy. As the initial investigations were non-contributory towards the aetiology, she was given steroids and later plasma exchange for symptomatic treatment. The differentials were revised again in view of no clinical and biochemical response. A repeat fine-needle aspiration cytology of the thyroid nodule (seen on positron emission tomography/CT) revealed papillary carcinoma of the thyroid. The patient underwent total thyroidectomy. There was a complete normalisation of liver function tests and serum calcium, and resolution of pruritus 3 months post surgery. She was retrospectively diagnosed as a case of papillary carcinoma of the thyroid with paraneoplastic manifestations-hypercalcaemia and cholestatic jaundice-which got resolved with treatment of the primary tumour.

Effectiveness, safety, and factors associated with the clinical success of endoscopic biliary drainage for patients with hepatocellular carcinoma: a retrospective multicenter study.

BACKGROUND: Only a few reports have assessed the effectiveness of endoscopic biliary drainage (EBD) in hepatocellular carcinoma (HCC) patients with obstructive jaundice and liver dysfunction. METHODS: This was a retrospective study based on the clinical databases from the Okayama University Hospital and 10 affiliated hospitals. All patients received EBD for jaundice or liver dysfunction. The indication for EBD was aggravation of jaundice or liver dysfunction with intrahepatic bile duct (IHBD) dilation. The technical and clinical success rate, complications, factors associated with clinical failure, and survival duration were evaluated. RESULTS: A total of 107 patients were enrolled in this study. Technical success was achieved in 105 of 107 patients (98.1%). Clinical success was achieved in 85 of 105 patients (81%). Complications related to endoscopic retrograde cholangiography (ERC) occurred in 3 (2.8%) patients. Child-Pugh class C (odds ratio 3.90, 95% confidence interval [CI] 1.47-10.4, p = 0.0046) was the only factor associated with clinical failure, irrespective of successful drainage. The median survival duration was significantly longer in patients with clinical success than in those without clinical success (5.0 months vs. 0.93 months; hazard ratio [HR] 3.2, 95% CI 1.87-5.37). HCC Stage I/II/III (HR 0.57, CI 0.34-0.95, p = 0.032), absence of portal thrombosis (HR 0.52, CI 0.32-0.85, p = 0.0099), and clinical success (HR 0.39, CI 0.21-0.70, p = 0.0018) were significant factors associated with a long survival. CONCLUSIONS: EBD for obstructive jaundice and liver dysfunction in patients with HCC can be performed safely with a high technical success rate. Clinical success can improve the survival duration, even in patients expected to have a poor prognosis. TRIAL REGISTRATION: Retrospectively registered.

Specialist shortage in developing countries: comprehending delays in care.

We describe a case of a middle-aged woman who presented with progressive jaundice and was suspected to have rebound choledocholithiasis, which was initially managed with balloon extraction through endoscopic retrograde cholangiopancreatography at her first presentation. Healthcare in Pakistan, like many other developing countries, is divided into public and private sectors. The public sector is not always completely free of cost. Patients seeking specialised care in the public sector may find lengthy waiting times for an urgent procedure due to a struggling system and a lack of specialists and technical expertise. Families of many patients find themselves facing 'catastrophic healthcare expenditure', an economic global health quandary much ignored.

Mucin-filled CBD, difficult to manage cholangitis.

Intraductal papillary mucinous neoplasms (IPMNs) are mucin-secreting cystic neoplasm of pancreas. They have a malignant potential. They are usually localised to the pancreas but occasionally can involve surrounding structures (1.9%-6.6%), like bile duct and duodenum, and are labelled as IPMN with invasion. Jaundice as a manifestation of IPMN is not common (4.5%). It can present as jaundice as a result of invasion of common bile duct (CBD) resulting in stricture formation or uncommonly as a result of fistulising to CBD with resultant obstruction of CBD by thick mucin secreted by this tumour. As only few cases (around 23) of mucin-filled CBD are reported in the literature. We are presenting our experience in dealing a rare case of obstructive jaundice caused by IPMN fistulising into CBD, highlighting the difficulties faced in managing such case, especially with regards to biliary drainage and what can be the optimum management in such cases.
