RESUMO
Objective:To evaluate the efficacy and safety of digital cholangioscopy-assisted non-radiation endoscopic retrograde cholangiopancreatography (ERCP) for common bile duct stones.Methods:Clinical data of patients who underwent digital cholangioscopy-assisted non-radiation ERCP for common bile duct stones from May 2019 to September 2021 were reviewed. The baseline data, the success rate of cannulation, the one-time success rate of endoscopic stone removal, the operation time, total hospital stay, complications, and recurrence of bile duct stones were analyzed.Results:A total of 170 patients were included, and bile duct stones were detected in 156 (91.8%) patients with the long diameter of 7.7±4.1 mm under preoperative imaging examination. Bile duct stones were detected under choledochoscopy and were successfully removed by using digital cholangioscopy through non-radiation ERCP. The success rate of cannulation was 100.0% (170/170) . The one-time success rate of endoscopic stone removal was 96.5% (164/170), and 6 patients (3.5%) received secondary stone removal for large stones (long diameter>30 mm).The time of biliary exploration and whole non-radiation ERCP were 9.6±2.7 min (6-24 min) and 35.9±17.3 min (13-85 min), respectively. The total hospital stay was 6.3±2.2 days (5-10 days). Postoperative pancreatitis occurred in 3 patients (1.8%), all of whom were mild and resolved after symptomatic treatment. No recurrence of bile duct stones was seen in any patient over 1-month postoperative follow-up.Conclusion:Digital cholangioscopy-assisted non-radiation ERCP is safe and effective for common bile duct stones without ray exposure, which is worth of promotion.
RESUMO
Objective: Bile duct tumor thrombosis in hepatocellular carcinoma (HCC) is a relatively rare event with a poor prognosis. Furthermore, bile duct tumor thrombus in HCC may be misdiagnosed when only imaging modalities are used. The efficiency of peroral cholangioscopy (POCS) in evaluating bile duct lesions has been reported.Patients: We present three cases of HCC with bile duct strictures in which POCS was performed as a preoperative evaluation.Results: In these three cases, diagnosing whether the lesion was a bile duct tumor thrombus on CT and endoscopic retrograde cholangiopancreatography was difficult. We performed POCS in three cases and were able to diagnose the presence of bile duct tumor thrombus of HCC, including differentiation from extrinsic compression of the bile duct.Conclusion: POCS for HCC with bile duct features is useful for the preoperative diagnosis of bile duct tumor thrombus, especially in cases where the surgical procedure depends on the presence of bile duct tumor thrombus.
RESUMO
Objective To evaluate the clinical efficacy of endoscopic retrograde cholangiopancreatography (ERCP)-based comprehensive minimally invasive treatment for biliary anastomotic stenosis (BAS) after liver transplantation. Methods Clinical data of 60 BAS recipients after liver transplantation were retrospectively analyzed, 54 male and 6 female, aged (48±10) years. ERCP was initially carried out. If it succeeded, plastic or metallic stents were placed into the biliary tract. If it failed, percutaneous transhepatic cholangial drainage (PTCD) or single-operator cholangioscopy (SpyGlass) was adopted to pass through the stenosis. If all these procedures failed, magnetic anastomosis or other special methods were delivered. The incidence and treatment of BAS after liver transplantation were summarized. The efficacy, stent removal and recurrence were observed. Results The median time of incidence of BAS after liver transplantation was 8 (4, 13) months. Within postoperative 1 year, 1-2 years and over 2 years, 39, 16 and 5 recipients were diagnosed with BAS, respectively. All 60 BAS recipients after liver transplantation were successfully treated, including 56 cases initially receiving ERCP, and 41 completing BAS treatment, with a success rate of 73%. The failure of guide wire was the main cause of ERCP failure. The success rates of PTCD, SpyGlass and magnetic anastomosis were 5/9, 5/7 and 7/8, respectively. Two recipients were successfully treated by percutaneous choledochoscope-assisted blunt guide wire technique and stent placement in the biliary and duodenal fistula. After 3 (3, 4) cycles of ERCP and 13 (8, 18) months of stent indwelling, 38 recipients reached the stent removal criteria, including 25 plastic stents and 13 metallic stents. The indwelling time of plastic stents was longer than that of metallic stents (P < 0.05). Six cases suffered from stenosis recurrence at 12 (8, 33) months after stent removal, and the recurrence rate was 16%. Six patients were treated with ERCP, and 5 of them did not recur after the stents were successfully removed. Multivariate analysis showed that delayed diagnosis of stenosis and frequent ERCP before stent removal were the independent risk factors for BAS recurrence (both P < 0.05). Conclusions ERCP-based comprehensive minimally invasive treatment may improve the success rate of BAS treatment after liver transplantation and yield satisfactory long-term efficacy. Delayed diagnosis of BAS and high frequent ERCP required for stent removal are the independent risk factors for BAS recurrence.
RESUMO
Objective:To study the treatment outcomes of combining percutaneous transhepatic one-step biliary fistulation (PTOBF) followed by two stages cholangioscopic treatment for type Ⅰ and Ⅱa hepatolithiasis which developed after Roux-en-Y cholangiojejunostomy, and in treatment of cholangiojejunostomy stenosis.Methods:The clinical data of 95 patients with type Ⅰ and Ⅱa hepatolithiasis which developed after Roux-en-Y cholangiojejunostomy and were treated at Shandong Second Provincial General Hospital from September 2016 to December 2020 were analyzed retrospectively. There were 36 males and 59 females, with the age of (51.2±15.3) years (range 14 to 75 years). These patients initially underwent PTOBF rigid choledochoscopy, followed by electronic choledochoscopy via the fistula tract after 6-8 weeks. The hepatolithiasis removal, complications and hepatolithiasis recurrence rates, and the cholangio-intestinal anastomotic stenosis rate and treatments were recorded. The follow-up was performed to analyse prognosis.Results:All 95 patients successfully underwent PTOBF rigid choledochoscopy and electronic choledochoscopy via the fistula tract. In 92 patients (96.8%), stones were completely removed. In 3 patients, small amounts of peripheral bile duct stones were left behind. Of 49 patients had cholangio-intestinal anastomotic strictures. On cholangioscopic examination, the strictures were caused by anastomotic knots in the suture line in 25 patients and cicatricial stenosis in 24 patients. After biliary balloon dilation and removal of anastomotic suture line knots, the strictures were relieved in 49 patients. There were 2 patients who developed biliary bleeding and 2 patients pleural effusion after PTOBF rigid choledochoscopy. Hepatolithiasis recurred in 4 patients in 6 to 36 months later.Conclusion:PTOBF followed by two stages cholangioscopic treatment were safe and effective in treatment of type Ⅰ and Ⅱa hepatolithiasis after Roux-en-Y cholangiojejunostomy. A high hepatolithiasis removal rate was obtained. Balloon dilation and removal of biliary intestinal anastomotic suture knots effectively relieved biliary intestinal anastomotic stenosis. The long-term results needs to be further determined.

Objective To observe the clinical effect of percutaneous transhepatic one-step biliary fistulation (PTOBF) and percutaneous transhepatic cholangioscopy (PTCS) in the treatment of hepatolithiasis with hepatobiliary surgery history,and to explore the clinical application value of PTOBF.Methods This is retrospective analysis of 68 patients with hepatolithiasis who were admitted to hepatobiliary surgery in the First Affiliated Hospital of Guangzhou Medical University from November 2009 to October 2017.Among these cases,35 patients in the observation group (group PTOBF) were treated with PTOBF,and 33 patients in the control group (group PTCS) received PTCS treatment.The final clearance rate,the postoperative complications rate,the hospitalization time,the operation times within the course of treatment,the recurrence rate and the residual stenosis rate of the two groups were compared.Results Compared with group PTCS,the clearance rate was significantly higher in group PTOBF(82.9% vs 54.6%,P<0.05),while the postoperative complications rate between the two groups are similar (14.3 % vs 30.3 %,P> 0.05);Besides,the hospitalization time(12.3±5.3 d vs 17.4±7.0 d,P<0.05),the operation times within the course of treatment (2.2±1.3 vs 2.8±1.0,P<0.05) and the recurrence rate(17.4% vs 39.4%,P<0.05) of group PTOBF were obviously lower.Conclusions PTOBF is a safe and feasible treatment for hepatolithiasis with hepatobiliary surgery history.Compared with PTCS,it has the advantages of short hospitalization time,fewer operations and better recovery.
RESUMO
Although endoscopic retrograde cholangiopancreatography (ERCP) is the first-line treatment for benign biliary diseases, this procedure is technically difficult in some conditions such as a surgically altered anatomy and gastric outlet obstruction. After a failed ERCP, a surgical or a percutaneous approach is selected as a rescue procedure; however, various endoscopic ultrasound (EUS)-guided interventions are increasingly utilized in pancreatobiliary diseases, including EUS-guided rendezvous for failed biliary cannulation, EUS-guided antegrade treatment for stone management, and EUS-guided hepaticogastrostomy for anastomotic strictures in patients with a surgically altered anatomy. There are some technical hurdles in EUS-guided interventions for benign biliary diseases owing to the difficulty in puncturing a relatively small bile duct and in subsequent guidewire manipulation, as well as the lack of dedicated devices. A recent major advancement in this field is the introduction of a 2-step approach, in which EUS-guided drainage is placed in the first session and antegrade treatment is performed in subsequent sessions. This approach allows the use of various techniques such as mechanical lithotripsy and cholangioscopy without a risk of bile leak. In summary, EUS-guided interventions are among the treatment options for benign biliary diseases; however, standardization of the procedure and development of a treatment algorithm are needed.

BACKGROUND/AIMS: Percutaneous transhepatic cholangioscopy (PTCS) is an effective treatment used for intrahepatic stone in patients who have undergone hepatectomy. There are few reports on natural course in these patients. Thus, we report the long-term results. METHODS: We conducted a retrospective study of 19 patients who underwent PTCS after hepatectomy at Samsung Medical Center between January 1998 and December 2014. We investigated patient characteristics and recurrence of biliary complications during follow up period. Then, we analyzed the factors related to recurrence. RESULTS: Indications for PTCS were cholangitis, symptomatic stone, liver abscess and biliary dilatation. Complete stone removal was achieved in 12 patients (63.2%). After receiving PTCS, the recurrence of intrahepatic stone related complication occurred in 52.6% (10/19) of patients during a median follow-up of 4.9 years (range, 1.8–7.8). Complications were cholangitis (5/10, 50%), cholangitis with liver abscess (3/10, 30%), liver abscess (1/10, 10%) and symptomatic stone (1/10, 10%). On univariate analysis, factors including multiple stone involvement, complete stone removal and bile duct stricture were not significantly associated with recurrent biliary complications. CONCLUSIONS: PTCS is an effective treatment for complications of recurrent intrahepatic stones in patients who have undergone hepatectomy. However, long term follow-up is necessary because of the recurrence of biliary complications.

An 89-year-old man was referred to our hospital for treatment of hepatolithiasis causing recurrent cholangitis. He had undergone a prior Whipple procedure. Computed tomography demonstrated left-sided hepatolithiasis. First, we conducted peroral direct cholangioscopy (PDCS) using an ultraslim endoscope. Although PDCS was successfully conducted, it was unsuccessful in removing all the stones. The stones located in the B2 segment were difficult to remove because the endoscope could not be inserted deeply into this segment due to the small size of the intrahepatic bile duct. Next, we substituted the endoscope with an upper gastrointestinal endoscope. After positioning the endoscope, the SpyGlass digital system (SPY-DS) was successfully inserted deep into the B2 segment. Upon visualizing the residual stones, we conducted SPY-DS-guided electrohydraulic lithotripsy. The stones were disintegrated and completely removed. In cases of PDCS failure, a treatment strategy using the SPY-DS can be considered for patients with hepatolithiasis after a Whipple procedure.

Intrahepatic duct (IHD) stone is the presence of calculi within the intrahepatic bile duct specifically located proximal to the confluence of the left and right hepatic ducts. This stone is characterized by its intractable nature and frequent recurrence, requiring multiple therapeutic interventions. Without proper treatment, biliary strictures and retained stones can lead to repeated episodes of cholangitis, liver abscesses, secondary biliary cirrhosis, portal hypertension, and death from sepsis or hepatic failure. The ultimate treatment goals for IHD stones are complete removal of the stone, the correction of the associated strictures, and the prevention of recurrent cholangitis. A surgical resection can satisfy the goal of treatment for hepatolithiasis, i.e., complete removal of the IHD stones, stricture, and the risk of cholangiocarcinogenesis. On the other hand, in some cases, such as bilateral IHD stones, surgery alone cannot achieve these goals. Therefore, the optimal treatments require a multidisciplinary approach, including endoscopic and radiologic interventional procedures before and/or after surgery. Percutaneous transhepatic cholangioscopic lithotomy (PTCS-L) is particularly suited for patients at poor surgical risk or who refuse surgery and those with previous biliary surgery or stones distributed in multiple segments. PTCS-L is relatively safe and effective for the treatment of IHD stones, and complete stone clearance is mandatory to reduce the sequelae of IHD stones. An IHD stricture is the main factor contributing to incomplete clearance and stone recurrence. Long-term follow-up is required because of the overall high recurrence rate of IHD stones and the association with cholangiocarcinoma.

RESUMO
Objective To evaluate the clinical application value of SpyGlass DS cholangioscopy in diagnosis and therapy of patients with biliary tract diseases. Methods Seven patients with biliary tract diseases were examined and treated with SpyGlass DS system. Three patients with large choledocholithiasis underwent laser lithotripsy under SpyGlass DS system, and then the broken stones were removed by ERCP. Four patients with indeterminate bile duct stricture underwent SpyGlass DS examination and SpyGlass DS-guided biopsies if necessary.Results SpyGlass DS cholangioscopy was successfully performed in all patients with a mean procedure time of 12. 6 min. Complete stone clearance was achieved in 3 patients with large biliary stones. Of the 4 patients with indeterminate biliary stricture, 2 underwent SpyGlass DS-guided biopsies and were diagnosed as malignant biliary tumor; the other 2 patients were diagnosed as inflammatory bile duct stenosis after visualizing the target lesions without biopsy. Two patients developed hyperamylasemia after the procedure, and recovered spontaneously. Conclusion SpyGlass DS cholangioscopy can provide accurate diagnosis in indeterminate biliary strictures and facilitate therapy in patients with challenging biliary stones.
RESUMO
Biliary strictures are considered indeterminate when evaluation with imaging and standard tissue sampling during endoscopic retrograde cholangiopancreatography (ERCP) are non-diagnostic. Standard tissue sampling techniques include cytologic brushings, with or without fluorescence in situ hybridization (FISH), and endoscopic intraductal biopsies. These strictures are often clinically suspicious for malignancy. The management of these patients can vary substantially and relies on an accurate diagnosis of the lesion. Unfortunately, despite numerous modalities, the sensitivity of existing tissue sampling techniques remains low and can lead to delays in diagnosis and the need for additional procedures. Cholangioscopy has emerged as a means to visually inspect and obtain image-guided biopsies of the lesion in question, with improved sensitivity as well as a high specificity and accuracy for diagnosing the etiology of indeterminate biliary strictures. The types of cholangioscopy systems and a summary of the pertinent literature are discussed in this review.

RESUMO
Bilioenteric anastomosis strictures are a serious complication of biliary surgery, and often result in recurrent cholangitis, choledocholithiasis, biliary cirrhosis, and hepatic failure. Bilioenteric reconstructive surgery is the standard treatment of choice for such complications. However, percutaneous transhepatic cholangioscopy (PTCS), also known as per-oral endoscopic-guided intervention, is a less invasive procedure that is becoming an increasingly popular alternative. This review describes the PTCS procedure (including the preparation process), as well as the diagnostic and therapeutic role of PTCS in bilioenteric anastomosis strictures.

El 85% a 90% de los cálculos de la vía biliar son manejados de forma exitosa con la técnica endoscópica estándar, que incluye esfinterotomía endoscópica combinada con canastilla y/o catéter con balón. Sin embargo, cuando los cálculos son múltiples, de gran tamaño, de localización o forma inusual, o existen alteraciones anatómicas de la vía biliar se hacen refractarios al manejo estándar, lo que obliga la realización de otras modalidades terapéuticas. Los cálculos de gran tamaño o impactados generalmente son manejados con técnicas de fragmentación como la litotripsia mecánica y en casos fallidos con litotripsia electrohidráulica (LEH) o litotripsia láser (LL) guiado por colangioscopia convencional o más recientemente por un sistema de colangioscopia directa llamado Spyglass®. También se puede usar el sistema de dilatación endoscópica papilar con balón grande, que ha demostrado ser útil en el manejo de cálculos grandes y múltiples. En casos con anatomía alterada con dificultad para acceder a la papila, el abordaje preferido para la técnica de fragmentación es el percutáneo transhepático. En pacientes ancianos y con pobre estado general la colocación de una prótesis biliar es la técnica de elección definitiva mientras mejoran las condiciones del paciente para un tratamiento endoscópico posterior.
Standard endoscopic techniques of sphincterotomy combined with Dormia basket and/or balloon catheterization can manage 85-90% of the gallstones found obstructing bile ducts. However, when there are several large calculi, when a stone is in an unusual location, or when there are anatomic abnormalities of the bile duct, they become refractory to standard management. Other therapeutic modalities become essential for management of these gallstones. Large or impacted calculi are generally handled with fragmentation techniques such as mechanical lithotripsy. When this fails, electrohydraulic lithotripsy (LEH) or laser lithotripsy (LL) guided by conventional cholangioscopy are usually resorted to. More recently, a system of direct cholangioscopy called Spyglass has been introduced. Endoscopic papillary dilation with a large balloon has also proven useful for management of large and multiple calculi. In cases with altered anatomy that makes access to the papilla difficult, the preferred technique is a transhepatic approach combined with percutaneous fragmentation. In elderly patients whose overall condition is poor, the placement of a biliary stent is the definite choice of technique because it can improve the patients condition to make possible further endoscopic therapy.

La neoplasia mucinosa papilar es una enfermedad muy rara que usualmente se describe como ubicada en la vía pancreática. Presentamos un caso de una mujer con esta enfermedad aunque localizada en la vía biliar, lo cual es aún más infrecuente y constituye el primer caso descrito en Colombia. Hacemos una revisión de la literatura y una descripción de los exámenes que se usaron para llegar al diagnóstico, que incluyeron la utilidad de una nueva herramienta como es el Spyglass.
Papillary mucinous neoplasms are rare and are usually located in the pancreatic pathway. We present a case of a woman with this disease located in the bile duct, an even rarer occurrence. This is the first case in Colombia. We review the literature, describe the tests used for diagnosis, and include an evaluation of the usefulness of a new tool, the Spyglass.
