Background: Different techniques have been proposed to manage Cholecysto-choledocholithiasis (CCL) advantageously in one stage. Among these, Laparoendoscopic Rendezvous (LERV) addresses the CCL issue with a laparoscopic cholecystectomy, with insertion of a guide wire into the common bile duct through an incision of the cystic duct, followed by the clearance of the bile duct carried out by the endoscopists. The aim of this study was to evaluate the safety and the efficacy of the one-stage vs. a two-stage approach (pre-operative ERCP followed by cholecystectomy), and to compare our results with data from the current literature. Methods: All patients that underwent LERV in our facilities between January 2018 and December 2023 were evaluated. As a control group, we included patients that underwent a two-stage technique called the “sequential approach”. The primary outcome was to evaluate the efficacy in obtaining complete clearance of the common bile duct (CBD). The secondary outcomes included morbidity, mortality, operative time, conversion rate, hospital stay and CDB stone recurrence. Results: 120 patients in the LERV group were included; meanwhile, 70 patients underwent pre-operative ERCP plus cholecystectomy. A 97% bile duct clearance success rate in the LERV group and 93% in the ERCP group was observed, respectively. The median intraoperative time for the one-stage technique was 122 min (p < 0.001) and the median hospital stay was 4 days (p < 0.001). In the LERV group, an overall morbidity of 15% was reported (18/120): 15 Clavien–Dindo type 1, one type 3a and two type 3b (p < 0.001). At a median follow-up of 14 months, five patients experienced stone recurrence. In the ERCP group, we had a 93% success rate; meanwhile, we had longer hospitalization (p < 0.001), 27% post-ERCP pancreatitis (p < 0.001) and a cumulative morbidity of 30%. Conclusions: LERV offers the advantages of a being single-stage procedure and shorter hospitalization, with a lower risk of clinically relevant post-ERCP pancreatitis and failed CBD cannulation.

Background: In recent years, complicated biliary tract diseases are increasingly diagnosed in children. Laparoscopic exploration of the common bile duct (LCBDE) followed by laparoscopic cholecystectomy has gained popularity in children. The aim of this study was to investigate the outcomes of LCBDE in children and compare them with the treatment outcomes of previously used endoscopic retrograde cholangiopancreatography (ERCP). Methods: From January 2000 to January 2022, a total of 84 children (78.5% female) underwent laparoscopic cholecystectomy with a median follow-up of 11.4 (IQR 8, 14) years. Of these, 6 children underwent laparoscopic cholecystectomy (LC) + ERCP and 14 children underwent LCBDE for choledochiothiasis. The primary end point of the study was the success of treatment in terms of the incidence of complications, recurrence rate, and rate of reoperation. Secondary endpoints were stone characteristics, presenting symptoms, duration of surgery, and length of hospital stay. Results: The majority of patients were female in both groups (83.5% vs. 85.7%), mostly overweight with a median BMI of 27.9 kg/m² and 27.4 kg/m², respectively. Obstructive jaundice, colicky pain, acute pancreatitis, and obstruction of the papilla were the most common symptoms in both groups. The majority of patients (68%) had one stone, whereas two or more stones were found in 32% of patients. The median diameter of the common bile duct was 9 mm in both groups. The procedure was successfully completed in all patients in the ERCP group. In the group of patients treated with LCBDE, endoscopic extraction of the stone with a Dormia basket was successfully performed in ten patients (71.4%), while in the remaining four patients (28.6%) the stones were fragmented with a laser because extraction with the Dormia basket was not possible. The median operative time was 79 min in the LCBDE group (IQR 68, 98), while it was slightly longer in the ERCP group, 85 min (IQR 74, 105) (p = 0.125). The length of hospital stay was significantly shorter in the LCBDE group (2 vs. 4 days, p = 0.011). No complications occurred in the LCBDE group, while two (40%) complications occurred in the ERCP group: pancreatitis and cholangitis (p = 0.078). During the follow-up period, no conversions, papillotomies, or recurrences were recorded in either group. Conclusions: Exploration of the common bile duct and removal of stones by LCBDE is safe and feasible in pediatric patients for the treatment of choledocholithiasis. Through this procedure, choledocholithiasis and cholelithiasis can be treated in a single procedure without papillotomy or fluoroscopy. Compared with LC + ERCP, LCBDE is associated with a shorter hospital stay. The incidence of complications was rather low but not statistically significant. Full article

Secondary choledocholithiasis occurs when stones leave the gallbladder. After therapeutic endoscopic retrograde cholangiopancreatography (ERCP) with stone removal, cholecystectomy should be performed to prevent recurrence. However, the optimal timing for cholecystectomy in secondary choledocholithiasis patients is unclear. The aim of this study was to determine the optimal timing for laparoscopic cholecystectomy in patients with secondary choledocholithiasis. In total, 22,996 patients in the Taiwan National Health Insurance Research Database (NHIRD) who underwent laparoscopic cholecystectomy for acute cholecystitis from 1998–2015 were divided into three groups according to whether they underwent surgery as an inpatient (early cholecystectomy (ELC)), within 2 months of admission (intermediate cholecystectomy (ILC)), or 2 months after admission (delayed cholecystectomy (DLC)). The primary outcomes included the recurrence, complication, and mortality rates. After adjusting for confounders, according to the 2013 Tokyo guidelines (cut-off at 2013), a subgroup analysis showed that, compared to the ELC group, the ILC group had lower recurrence, complication, and mortality rates, whereas the DLC group exhibited statistically significantly higher recurrence and mortality rates. In conclusion, the optimal timing of cholecystectomy in secondary choledocholithiasis patients after preoperative ERCP is within 2 months (ILC) after hospital admission. Moreover, ELC is associated with a measurable risk of complications. Full article

Our case describes an 83-year-old female who presented with severe abdominal pain, nausea, and bilious emesis of one day’s duration. She had an endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy and percutaneous transhepatic biliary drainage (PTCD) one year prior for choledocholithiasis with acute cholangitis in her home country, Scotland. Unfortunately, while visiting family in the United States, her PTCD became dislodged, and she developed progressive worsening abdominal pain. Computerized tomography of her abdomen showed pneumobilia, perigastric inflammation, a contracted gallbladder, small bowl inflammation with a likely transition point at the mid-jejunum, and a probable duodenal mass. The patient underwent an exploratory laparotomy with intraoperative findings of choledochoduodenal fistula with coincident gastric and small bowel obstruction (SBO) secondary to three large, mixed gallstones. One 3 cm gallstone was located at the pylorus and two (2.3 and 3 cm) gallstones were isolated in the mid-jejunum, with one of those causing isolated transmural pressure necrosis with subsequent perforation. Bouveret syndrome is a rare cause of gastric outlet obstruction (GOO) that manifests via an acquired cholecystoenteric fistula. Our patient presented with a concomitant GOO and SBO with perforation of the mid-jejunum. Timely diagnosis of Bouveret syndrome is essential, as most causes require emergent surgical intervention.

Determination of the cause of a biliary obstruction is often inconclusive from serum analysis alone without further clinical tests. To this end, serum markers as well as the composition of bile of 74 patients with biliary obstructions were determined to improve the diagnoses. The samples were collected from the patients during an endoscopic retrograde cholangiopancreatography (ERCP). The concentration of eight bile salts, specifically sodium cholate, sodium glycocholate, sodium taurocholate, sodium glycodeoxycholate, sodium chenodeoxycholate, sodium glycochenodeoxycholate, sodium taurodeoxycholate, and sodium taurochenodeoxycholate as well as bile cholesterol were determined by HPLC-MS. Serum alanine aminotransferase (ALT), aspartate transaminase (AST), and bilirubin were measured before the ERCP. The aim was to determine a diagnostic factor and gain insights into the influence of serum bilirubin as well as bile salts on diseases. Ratios of conjugated/unconjugated, primary/secondary, and taurine/glycine conjugated bile salts were determined to facilitate the comparison to literature data. Receiver operating characteristic (ROC) curves were determined, and the cut-off values were calculated by determining the point closest to (0,1). It was found that serum bilirubin was a good indicator of the type of biliary obstruction; it was able to differentiate between benign obstructions such as choledocholithiasis (at the concentration of >11 µmol/L) and malignant changes such as pancreatic neoplasms or cholangiocarcinoma (at the concentration of >59 µmol/L). In addition, it was shown that conjugated/unconjugated bile salts confirm the presence of an obstruction. With lower levels of conjugated/unconjugated bile salts the possibility for inflammation and, thus, neoplasms increase. Full article

To compare two magnetic resonance cholangiopancreatography (MRCP) sequences at 3 Tesla (3T): the conventional 3D Respiratory-Triggered SPACE sequence (RT-MRCP) and a prototype 3D Compressed-Sensing Breath-Hold SPACE sequence (CS-BH-MRCP), in terms of qualitative and quantitative image quality and radiologist’s diagnostic confidence for detecting common bile duct (CBD) lithiasis, biliary anastomosis stenosis in liver-transplant recipients, and communication of pancreatic cyst with the main pancreatic duct (MPD). Sixty-eight patients with suspicion of choledocholithiasis or biliary anastomosis stenosis after liver transplant, or branch-duct intraductal papillary mucinous neoplasm of the pancreas (BD-IPMN), were included. The relative CBD to peri-biliary tissues (PBT) contrast ratio (CR) was assessed. Overall image quality, presence of artefacts, background noise suppression and the visualization of 12 separated segments of the pancreatic and bile ducts were evaluated by two observers working independently on a five-point scale. Diagnostic confidence was scored on a 1–3 scale. The CS-BH-MRCP presented significantly better CRs (p < 0.0001), image quality (p = 0.004), background noise suppression (p = 0.011), fewer artefacts (p = 0.004) and better visualization of pancreatic and bile ducts segments with the exception of the proximal CBD (p = 0.054), cystic duct confluence (p = 0.459), the four secondary intrahepatic bile ducts, and central part of the MPD (p = 0.885) for which no significant differences were found. Overall, diagnostic confidence was significantly better with the CS-BH-MRCP sequence for both readers (p = 0.038 and p = 0.038, respectively). This study shows that the CS-BH-MRCP sequence presents overall better image quality and bile and pancreatic ducts visualization compared to the conventional RT-MRCP sequence at 3T. Full article
