AIM: To determine the accuracy of Magnetic Resonance Cholangiopancreatography compared to the gold standard Endoscopic Retrograde Cholangiopancreatography in the diagnosis of bile duct disorders at our institution. PATIENTS AND METHODS: 52 patients with suspected pancreatobiliary pathology were included in this prospective observational study. MRCP was performed in the 24-hour period prior to the ERCP. RESULTS: MRCP had sensitivity, specificity, positive and negative predictive values of 87%, 80%, 83.3% and 84.2% respectively for choledocholitiasis which correlates well with results obtained in other parts of the world. CONCLUSION: At our institution, MRCP has high diagnostic accuracy for bile duct calculi. Due to a small study population, results for other biliary pathology were inconclusive

Objective: to analyze the diagnostic value of radiation techniques in patients with opisthorchiasis-induced obstructive jaundice and to determine the types of bile duct (BD) changes characteristic of this disease.Subjects and methods. The investigation enrolled 103 patients with chronic opisthorchiasis complicated by obstructive jaundice. For BD visualization, the investigators used radiation diagnostic methods, such as ultrasonography (USG), magnetic resonance cholangiopancreatography (MRCP), and endoscopic retrograde cholangiopancreatography (ERCP); their efficiency was evaluated.Results. ERCP and MRCP could identify 5 types of BD architectonics in opisthorchiasis-induced obstructive jaundice. The sensitivity, specificity, and overall accuracy of MRCP in diagnosing opisthorchiasis-induced sclerotic changes were 98.1, 87.5, and 96.8%, respectively.Conclusion. Among instrumental methods for diagnosing sclerotic BD changes in prolonged opisthorchiasis invasion, it is preferable to use MRCP, which is determined by its high informative value. Five types of cholangioarchitectonics are detectable in chronic opisthorchiasis complicated by obstructive jaundice.

Potential Benefits

Iatrogenic biliary injury is the most significant complication after laparoscopic cholecystectomy. We present our experience with an alternative diagnostic approach using transcatheter cholangiography (TCC) through a Jackson-Pratt (JP) drain and discuss potential benefits and limitations of the technique. From March 2002 to February 2012, 40 patients with major postoperative biliary injury underwent biliary reconstruction at our institution. Mean age was 51.7 ± 18.1 years (range, 19 to 86 years) with 30 (75%) females. Seventeen (42.5%) injuries were detected intraoperatively and in 13 (32.5%) cases, JP drains were placed for biliary drainage. Lesions were classified according to Bismuth grade: I (10 patients [25%]), II (10 patients [25%]), III (six patients [15%]), IV (10 patients [25%]), and V (four patients [10%]). TCC was performed in seven patients with JP drains (53.8%). It fully defined the injury site in three cases of limited magnetic resonance cholangiopancreatography (MRCP) such as common hepatic duct and common bile duct leaks and in four cases (57.1%) that endoscopic retrograde cholangiopancreatography (ERCP) was limited as a result of clipping of the distal common bile duct. TCC showed promising results in cases of limited MRCP and ERCP such as fistulous orifices or leakage. It may represent an alternative adjunct in the diagnostic armamentarium of complex biliary injuries.

There are several treatments available for choledocholithiasis, but the optimal treatment is highly debated. Some advocate preoperative endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy (LC) with cholangiography (IOC). Others advocate initial LC + IOC followed by common bile duct exploration or ERCP. The purpose of this study was to determine whether initial LC + IOC had a shorter length of stay (LOS) compared with preoperative magnetic resonance cholangiopancreatography (MRCP) or ERCP. Patients who underwent cholecystectomy between 2012 and 2013 at two institutions were reviewed. Patients were selected if they had suspected choledocholithiasis, indicated by dilated CBD and/or elevated bilirubin, or confirmed choledocholithiasis. They were excluded if they had pancreatitis or cholangitis. There were 126 patients with suspected choledocholithiasis in this study. Of these, 97 patients underwent initial LC ± IOC with an average LOS of 3.9 days. IOC was negative in 47.4 per cent patients, and they had a shorter LOS compared with positive IOC patients (2.93 vs 4.82, P < 0.001). Laparoscopic common bile duct exploration was successful in 64.7 per cent and had a shorter LOS compared with postoperative ERCP patients ( P = 0.01). Preoperative MRCP was performed in 21 patients with an average LOS of 6.48 days. Preoperative ERCP was performed in eight patients with an average LOS of seven days. Initial LC+IOC is associated with a shorter LOS compared to preoperative MRCP or ERCP. It is recommended as the optimal treatment choice for suspected choledocholithiasis.

Sickle Cell Crisis

Bilothorax is a rare cause of an exudative pleural effusion. The diagnosis is confirmed by a pleural fluid to serum bilirubin ratio of greater than 1. Typically, bilothorax presents as a right-sided effusion due to its proximity to the liver and biliary system. Herein, we present a case of isolated left-sided bilothorax in a 43-year-old female admitted with sickle cell crisis. Only one other case of isolated spontaneous left-sided bilothorax has been described in the literature. A thoracentesis performed on admission demonstrated greenish fluid and bilothorax was suspected, with a pleural fluid to serum bilirubin ratio greater than 1 confirming the diagnosis. A magnetic resonance cholangiopancreatography (MRCP) showed an abnormal 90-degree acute angulation in the mid-to-distal common bile duct with proximal common bile duct and intrahepatic bile ducts dilation. This was further confirmed with an endoscopic retrograde cholangiopancreatography (ERCP), which did not reveal any extravasation of contrast into the left pleural space. Ultimately, despite the use of various modalities, no definitive cause of bilothorax was identified. Postthoracentesis imaging revealed evidence of fibrothorax, a direct and permanent complication of bilothorax. The presence of an isolated left-sided bilothorax, along with the lack of a confirmed etiology, makes this case unique.

Antigen Testing

Testing cerebrospinal fluid (CSF) for the presence of galactomannan (GM) antigen may help in diagnosing cerebral aspergillosis (CA). However, the use of the CSF GM test as a diagnostic test has been little studied. We evaluated its diagnostic performance by comparing the CSF GM optical density indexes (ODI) at different cutoffs in patients with probable and proven CA to those in patients without CA. Patients from 2 tertiary referral hospitals with suspected CA between 2004 and 2014 and in whom CSF GM ODI had been determined were selected. European Organization for Research and Treatment of Cancer/Invasive Infectious Diseases Study Mycoses Group (EORTC/MSG) definitions of invasive aspergillosis and CA were used, but with the exclusion of the test to be validated (i.e., the CSF GM test) as a microbiological EORTC/MSG criterion. The study population consisted of 44 patients (4 with proven CA, 13 with probable CA, and 27 with no CA). Of the 17 patients with CA, 15 had a CSF GM ODI of ≥2.0. Of 27 patients without CA, 26 had a CSF GM ODI of <0.5 and 1 had a CSF GM ODI of 8.2. When a GM CSF ODI cutoff of 1.0 was used, the sensitivity, specificity, and positive and negative predictive values were 88.2%, 96.3%, 93.8%, and 92.9%, respectively. The same results were found when a CSF GM ODI cutoff of 0.5 or 2.0 was used. Testing GM in CSF has a high diagnostic performance for diagnosing CA and may be useful to diagnose or virtually rule out the infection without the need for a cerebral biopsy.

Fatal Complications

Gallbladder (GB) stones are commonly associated with common bile duct stones (CBDS). While they may remain asymptomatic, some may present with symptoms like biliary colic, jaundice and cholecystitis. Most of these stones in the CBD, if small, pass through faeces. Passing larger stones through faeces is relatively rare and if it does occur, is usually associated with fatal complications like acute pancreatitis. The authors reported a case wherein symptomatic large CBD stones were spontaneously passed through faeces and the patient was relieved of the symptoms and did not suffer any further complications. Choledocholithiasis is usually managed by endoscopic retrograde cholangiopancreatography or by laparoscopic or open choledocholithotomy. Spontaneous passage of small CBD and GB calculi through faeces although common is associated often with the development of pancreatitis. Passage of large CBD calculi (size >1.5 cm) through faeces is rarely seen.

This is a prospective study done to compare the diagnostic accuracy of Magnetic Resonance Cholangiopancreatography (MRCP) in patients undergoing Endoscopic Retrograde Cholangiopancreatography (ERCP) for pancreaticobiliary disorders.Majority of the study participants were males (63.3%), while the rest 36.78% of them were females and periampullary carcinoma (11.7%) and common bile duct calculus (11.7%) are the common cause of obstruction found on MRCP followed by malignant stricture (10%). The extent of obstruction was determined in most of the study participants (91.7%) by MRCP while the rest 8.3% were not determined by MRCP. The Common bile duct calculus (11.7%) is the common cause of obstruction on ERCP followed by malignant stricture (10%) and Periampullary carcinoma (10%) and 20% of the patients were found to be normal in ERCP. Among them, 71.4 % did not show MRCP and the association was found to be significant. (p- Value < 0.00).

Therapeutic Tools

Previously, when a surgeon diagnosed bile duct lithiasis, he/she performed cholecystectomy, choledocotomy, stone removal and placement of a Kehr’s “T” tube. Some cases might require sphincteroplasty or bilio-digestive bypass. Nowadays, magnetic resonance cholangiopancreatography, endoscopic retrograde cholangiopancreatography, endoscopic ultrasound and intraoperative ultrasound have emerged as diagnostic and therapeutic tools. Decision-making processes are complex and there is no conclusive evidence supporting them. Many studies have focused on the matter with a non-comprehensive approach so that each surgeon will use his/her common sense for each individual case. The optimal management of the common bile duct is still controversial. Deciding on endoscopic, laparoscopic or conventional management requires adequate training and clinical judgment. Conventional surgery is still in valid option.
