Rendezvous Technique Using Double Balloon Endoscope for Removal of Multiple Intrahepatic Bile Duct Stones in Hepaticojejunostomy After Living Donor Liver Transplant: A Case Report

Stone removal by percutaneous papillary balloon dilatation for cystic duct and bile duct stones after cholecystectomy and distal gastrectomy with Roux-en-Y gastrojejunostomy

A 71-year-old woman was referred to our department for abdominal pain. She was diagnosed with acute obstructive cholangitis due to cystic duct and bile duct stones after cholecystectomy and Roux-en-Y gastrojejunostomy. Two years ago, the patient underwent endoscopic and laparoscopic treatment for cystic duct and bile duct stones, however, the stones remained. This time, she was treated with stone removal using percutaneous papillary balloon dilatation (PPBD). Large stones in the common hepatic and bile ducts were crushed by electrohydraulic lithotripsy and then pushed out into the duodenum through the dilated papilla of Vater using a balloon catheter covered with the sheath and cholangioscopy. Stone in the cystic duct was pulled to the common bile duct and pushed to the duodenum. Stone removal using PPBD is an excellent alternative for patients with cystic duct and bile duct stones unable to be treated with endoscopic or laparoscopic stone removal.

Double-balloon endoscopic retrograde cholangiography can make a reliable diagnosis and good prognosis for postoperative complications of congenital biliary dilatation

Bile duct and anastomotic strictures and intrahepatic stones are common postoperative complications of congenital biliary dilatation (CBD). We performed double-balloon endoscopic retrograde cholangiography (DBERC) for diagnostic and therapeutic purposes after radical surgery. We focused on the effectiveness of DBERC for the treatment of postoperative complications of CBD patients. Bile duct and anastomotic strictures and intrahepatic stones are common postoperative complications of congenital biliary dilatation (CBD). We performed double-balloon endoscopic retrograde cholangiography (DBERC) for diagnostic and therapeutic purposes after radical surgery. We focused on the effectiveness of DBERC for the treatment of postoperative complications of CBD patients. This retrospective study included 28 patients who underwent DBERC (44 procedures) after radical surgery for CBD between January 2011 and December 2019. Strictures were diagnosed as “bile duct strictures” if endoscopy confirmed the presence of bile duct mucosa between the stenotic and anastomotic regions, and as “anastomotic strictures” if the mucosa was absent. The median patient age was 4 (range 0–67) years at the time of primary surgery for CBD and 27.5 (range 8–76) years at the time of DBERC. All anastomotic strictures could be treated with only by 1–2 courses of balloon dilatation of DBERC, while many bile duct strictures (41.2%) needed ≥ 3 treatments, especially those who underwent operative bile duct plasty as the first treatment (83.3%). Although the study was limited by the short follow-up period after DBERC treatment, DBERC is recommended as the first-line treatment for hepatolithiasis associated with biliary and anastomotic strictures in CBD patients, and it can be safely performed multiple times.

The use of percutaneous-endoscopic rendezvous stenting in a patient with bile duct injury after cholecystectomy-and a unique complication requiring secondary endoscopic intervention

Bile duct injury (BDI) is a potentially devastating complication after cholecystectomy. Familiarity with the diagnosis and multidisciplinary treatment options is imperative. This report highlights the utility of the rendezvous stenting procedure in a high-risk patient and describes a rare complication involving stent misplacement through the surgical drain. This is a 96-year-old female patient who suffered a Strasburg Class D injury during cholecystectomy, repaired over a T-tube. The T-tube dislodged postoperatively. Endoscopic and transhepatic stenting attempts were unsuccessful. Ultimately, a rendezvous approach allowed successful deployment of a covered metal stent. The stent was inadvertently deployed through a side fenestration of a surgical drain and was explanted upon drain removal. Repeat endoscopic stent placement was successful. The patient recovered without further complication. Surgical drains near the BDI can become sources of unexpected complications. A higher index of suspicion and careful interpretation of procedural imaging studies may prevent this complication.

Combined endoscopy/laparoscopy/percutaneous transhepatic biliary drainage, hybrid techniques in gastrointestinal and biliary diseases

In recent years, a wide range of gastrointestinal endoscopy techniques have been developed, such as endoscopic submucosal dissection (ESD) and endoscopic retrograde cholangiopancreatography (ERCP). Although ESD and ERCP have an important role in gastrointestinal and biliary diseases, each technique has its limitations. Hybrid techniques that combine endoscopic and surgical procedures have emerged that have the advantages of different procedures and negate their limitations at the same time. Laparoscopic endoscopic cooperative surgery and modified laparoscopic endoscopic cooperative surgery combine ESD and laparoscopic techniques to resect submucosal tumors with minimum resection area. Air leak test by intraoperative endoscopy can effectively identify a mechanically insufficient anastomosis and decrease the complication rate. The rendezvous technique that combines percutaneous transhepatic biliary drainage and endoscopy can be performed as a rescue approach for the treatment of biliary obstruction, stenosis and bile duct injuries. For patients with simultaneous presence of stones in the gallbladder and the common bile duct, the laparo-endoscopic rendezvous technique can perform ERCP and laparoscopic cholecystectomy at the same time and reduces the risk of pancreatic injury caused by ERCP. Biliobiliary and bilioenteric anastomosis using magnetic compression anastomosis is another choice for biliary obstruction. The most common used approach to deliver the magnets is by percutaneous-peroral tract. Laparoscopic-assisted ERCP is a safe and highly effective therapy for patients who develop biliary diseases after Roux-en-Y gastric bypass surgery.

Percutaneous removal of biliary stones post-liver transplant in a pediatric patient: Case report and review of the literature

This case report describes an 8-year-old girl who underwent a segmental LT for a primary diagnosis of citrullinemia at the age of 12 months. She presented with cholangitis secondary to stenosis of the biliary-enteric anastomosis. MRI revealed dilatation of intrahepatic bile ducts associated with multiple stones. An endoscopic approach failed to decompress the bile ducts and remove the stones. A percutaneous approach was then undertaken. After placement of a temporary external biliary drain for 12 days, a 26 French sheath was placed to access the bile ducts. Using a 14Fr flexible cystoscope, 80%-90% of the biliary stones were removed. This was followed by antegrade balloon dilatation of the biliary-enteric anastomosis. Two months later, the procedure was repeated, resulting in complete clearance of the biliary stones. An internal-external biliary drain was maintained in placed for 10 months. The patient has been asymptomatic, with no evidence of stone recurrence for 13 months after drain removal. Percutaneous biliary stone removal is commonly performed in adults with non-transplanted livers, especially in complex cases, and has also been shown to be successful in the pediatric population. However, it is rarely reported in transplanted livers in adults, and to the best of our knowledge, no pediatric cases have been reported. This case illustrates that this technique can be successfully utilized in pediatric LT patients.

Electrohydraulic lithotripsy and rendezvous nasal endoscopic cholangiography for common bile duct stone: A case report

BACKGROUND

In patients with large stones in the common bile duct (CBD), advanced treatment modalities are generally needed. Here, we present an interesting case of a huge CBD stone treated with electrohydraulic lithotripsy (EHL) by the percutaneous approach and rendezvous endoscopic retrograde cholangiography (ERC) using a nasal endoscope.

CASE SUMMARY

A 91-year-old woman underwent ERC for a symptomatic large CBD stone with a diameter of 50 mm. She was referred to our institution after the failure of lithotomy by ERC, and after undergoing percutaneous transhepatic biliary drainage. We attempted to fragment the stone by transhepatic cholangioscopy using EHL. However, the stones were too large and partly soft clay-like for lithotripsy. Next, we attempted lithotomy with ERC and cholangioscopy by the rendezvous technique using a nasal endoscope and achieved complete lithotomy. No complication was observed at the end of this procedure.

CONCLUSION

Cholangioscopy by rendezvous technique using a nasal endoscope is a feasible and safe endoscopic method for removing huge CBD stones.
