A girl who was born at 40 weeks of gestation weighing 3800 g presented with bilious vomiting and abdominal distension shortly after birth. A lower gastrointestinal contrast study showed a microcolon with small bowel atresia. Subsequently, laparotomy, small bowel resection and anastomosis were done. Intra-operative findings noted jejunal atresia type 3a. Post-operatively, the patient developed persistent conjugated hyperbilirubinaemia and hence, magnetic resonance cholangiopancreatography (MRCP) was performed. MRCP revealed possible biliary atresia (BA) of which the patient underwent Kasai hepato-porto-enterostomy. We reported a rare case of double pathology involving jejunal atresia and BA, describing its aetiology, characteristics and treatment availability based on literature., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Objectives: Cholecystectomy with or without intraoperative cholangiogram (IOC) is an accepted treatment for cholelithiasis. Up to 11.6 % of cholecystectomies have incidental common bile duct (CBD) stones on IOC and 25.3 % of undiagnosed CBD stones will develop life-threatening complications. These will require additional intervention after primary cholecystectomy, further straining the healthcare system. We seek to examine the role of IOC in patients with normal LFTs by evaluating its predictive values, intending to treat undiagnosed CBD stones and therefore ameliorate these issues., Methods: All patients who underwent cholecystectomies with normal LFTs from October 2019 to December 2020 were prospectively enrolled. IOC was done, ERCPs were performed for filling defects and documented as "true positive" if ERCP was congruent with the IOC. "False positives" were recorded if ERCP was negative. "True negative" was assigned to normal IOC and LFT after 2 weeks of follow-up. Those with abnormal LFTs were subjected to ERCP and documented as "false negative". Sensitivity, specificity, and predictive values were calculated., Results: A total of 180 patients were analysed. IOC showed a specificity of 85.5 % and a NPV of 88.1 % with an AUC of 73.7 %. The positive predictive value and sensitivity were 56.5 and 61.9 % respectively., Conclusions: Routine IOC is a specific diagnostic tool with good negative predictive value. It is useful to exclude the presence of CBD stones when LFT is normal. It does not significantly prolong the length of hospitalization or duration of the cholecystectomy hence reducing the incidence of undetected retained stones and preventing its complications effectively., Competing Interests: Competing interests: The authors state no conflict of interests., (© 2024 the author(s), published by De Gruyter, Berlin/Boston.)

Background: Hepatocellular carcinoma (HCC) among type-2 diabetes (T2D) patients is an increasing burden to diabetes management. This study aims to develop and select the best machine learning (ML) classification model for predicting HCC in T2D for HCC early detection., Methods: A case-control study was conducted utilising computerised medical records in two hepatobiliary centres. The predictors were chosen using multiple logistic regression. IBM SPSS Modeler® was used to assess the discriminative performance of support vector machine (SVM), logistic regression (LR), artificial neural network (ANN), chi-square automatic interaction detection (CHAID), and their ensembles., Results: Subjects (N = 424) were split into 60% training (n = 248) and 40% testing (n = 176) groups. The independent predictors identified were race, viral hepatitis, abdominal pain/discomfort, unintentional weight loss, statins, alcohol consumption, non-alcoholic fatty liver, platelet <150 ×10 3 /μL, alkaline phosphatase >129 IU/L, and alanine transaminase ≥25 IU/L. The performances of all models differed significantly (Cochran's Q-test,p = 0.001) but not between the ensembled and SVM model (McNemar test, p = 0.687). SVM model was selected as the best model due to its simplicity, high accuracy (85.28%), and high AUC (0.914). A web-based application was developed using the best model's algorithm for HCC prediction., Conclusions: If further validation studies confirm these results, the SVM model's application potentially augments early HCC detection in T2D patients., Competing Interests: The authors declare no conflict of interest., (© 2022 The Author(s).)

WHO declared worldwide outbreak of COVID-19 a pandemic on 11 March 2020. Healthcare authorities have temporarily stopped all elective surgical and endoscopy procedures. Nevertheless, there is a subset of patients who require emergency treatment such as aerosol-generating procedures. Herein, we would like to discuss the management of a patient diagnosed with impending biliary sepsis during COVID-19 outbreak. The highlight of the discussion is mainly concerning the advantages of concurrent use of aerosol protective barrier in addition to personal protective equipment practice, necessary precautions to be taken during endoscopy retrograde cholangiopancreatography and handling of the patient preprocedure and postprocedure., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2020.

A biliary fistula which may occur spontaneously or after surgery, is an abnormal communication from the biliary system to an organ, cavity or free surface. Spontaneous biliary-enteric fistula is a rare complication of gallbladder pathology, with over 90% of them secondary to cholelithiasis. Approximately 6% are due to perforating peptic ulcers. Symptoms of biliary-enteric fistula varies widely and usually non-specific, mimicking any chronic biliary disease. Cholecystoduodenal fistula causing severe upper gastrointestinal (UGI) bleed is very rare. Bleeding cholecystoduodenal fistula commonly requires surgical resection of the fistula and repair of the duodenal perforation. We describe the case of a previously healthy older patient who initially presented with symptoms suggestive of UGI bleeding. Bleeding could not be controlled endoscopically. When a laparotomy was performed, a cholecystoduodenal fistula was discovered and bleeding was noted to originate from the superficial branch of cystic artery., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2019.

The protein profile of serum samples from patients with amoebic liver abscess (ALA) was compared to those of normal individuals to determine their expression levels and to identify potential surrogate disease markers. Serum samples were resolved by two dimensional electrophoresis (2-DE) followed by image analysis. The up and down-regulated protein spots were excised from the gels and analysed by MS/MS. The concentration of three clusters of proteins i.e. haptoglobin (HP), α1-antitrypsin (AAT) and transferrin in serum samples of ALA patients and healthy controls were compared using competitive ELISA. In addition, serum concentrations of HP and transferrin in samples of patients with ALA and pyogenic liver abscess (PLA) were also compared. The results of the protein 2-DE expression analysis showed that HP cluster, AAT cluster, one spot each from unknown spots no. 1 and 2 were significantly up-regulated and transferrin cluster was significantly down-regulated in ALA patients' sera (p<0.05). The MS/MS analysis identified the unknown protein spot no.1 as human transcript and haptoglobin and spot no. 2 as albumin. Competitive ELISA which compared concentrations of selected proteins in sera of ALA and healthy controls verified the up-regulated expression (p<0.05) of HP and the down-regulated expression (p<0.01) of transferrin in the former, while there was no significant difference in AAT expression (p> 0.05). However, when ALA and PLA samples were compared, competitive ELISA showed significant increased concentration of HP (p<0.05) while transferrin levels were not different. In conclusion, this study showed that HP is a potential surrogate disease marker for ALA.

Vibrio cholerae infection is mainly caused acute diarrhoea disease. Bacteraemia due to non-O1 V. cholerae is rare and mainly reported in liver cirrhotic patients. We report one case of non-O1 V. cholerae bacteraemia in splenectomised thalassaemic patient who presented with septic shock secondary to abdominal sepsis. She had undergone emergency laporatomy and was managed in the intensive care unit for nine days. She was treated with meropenem and doxycyline and discharged well after fourteen days of admission. The V. cholerae was identified by API 20NE, serotype and polymerase chain reaction showed as non-O1, non-O139 strain. Besides known cholera-like toxin and El Tor hemolysin, with increasing reported cases of V. cholerae bacteraemia, there is possibility of other virulence factors that allow this organism to invade the bloodstream.
