Endoscopic retrograde cholangiopancreatography, lights and shadows: Handle with care

Hepatic subcapsular hematoma: A rare complication post-ERCP; a case report

INTRODUCTION

Endoscopic retrograde cholangiopancreatography (ERCP) is commonly used in gastroenterology wards for both diagnostic and therapeutic purposes. It doesn't however come free of complications. As a matter of fact, complications are reported in up to 10% of patients undergoing ERCP.

PATIENT CONCERNS

In this article, we report the case of a patient who underwent ERCP and sphincterotomy for choledocholithiasis. Twenty-four hours after the procedure, the patient developed sudden sharp abdominal pain and dropped her hemoglobin levels.

DIAGNOSIS

An emergent gastroscopy was done and it ruled out bleeding from the sphincterotomy. Computed tomography of the abdomen showed a large hepatic subcapsular hematoma.

INTERVENTIONS

Blood was urgently transfused and the patient was transferred to the intensive care unit for monitoring.

OUTCOMES

The patient's condition quickly deteriorated despite extensive resuscitative measures, and eventually passed away on day 4 post ERCP.

LESSONS

Hepatic subcapsular hematoma is a very rare but fatal complication after ERCP and should be ruled out in patients who underwent the procedure and develop sudden abdominal pain with hemodynamic and laboratory instability.

Value of enhanced recovery after surgery in patients undergoing endoscopic retrograde cholangiopancreatography with intravenous anaesthesia for choledocholithiasis: a retrospective observational study

Introduction

Enhanced recovery after surgery (ERAS) is rarely used in minimally invasive endoscopic surgery, especially in endoscopic retrograde cholangiopancreatography (ERCP).

Aim

This study evaluated the safety and efficacy of the ERAS protocol in patients undergoing ERCP for choledocholithiasis.

Material and methods

The study had a retrospective design and included patients with biliary tract stones who underwent ERCP between June 2019 and November 2022. Patients who received the ERAS protocol between June 2021 and November 2022 were enrolled as an ERAS group, and those who received traditional perioperative treatment between December 2019 and May 2021 were enrolled as a control group.

Results

A total of 349 patients were enrolled (ERAS group, n = 185; control group, n = 164). The cannulation and stone extraction success rates were significantly higher in the ERAS group than in the control group (p < 0.05). The incidence of postoperative pancreatitis was significantly lower in the ERAS group (p = 0.02), but there were no significant differences in other complications. The postoperative hospital stay was significantly shorter in the ERAS group than in the control group (p < 0.001), with no statistically significant differences in costs according to surgical period, or in total costs, between the 2 groups.

Conclusions

Application of the ERAS protocol is safe and feasible in patients undergoing ERCP for choledocholithiasis. The ERAS protocol can accelerate recovery, reduce postoperative pain, and shorten the hospital stay without increasing the cost of treatment.

Our experiences in 1000 case single-centre endoscopic retrograde cholangiopancreatography

Background

Endoscopic retrograde cholangiopancreatography (ERCP) has a very important role in both diagnosis and treatment of pancreaticobiliary pathologies. The aim of this study was to review the indications, technical success complications and results of ERCP procedures performed in our centre.

Materials and Methods

In the study, the data of 1000 patients who were diagnosed with extrahepatic cholestasis, obstructive cholangitis/pancreatitis or bile leakage in clinical, medical and radiological data and who underwent ERCP between May 2019 and November 2021 were evaluated retrospectively.

Results

The age distribution was between 14 and 109 years, and the average age was 57.97 years for women (14-109) and 57.48 for men (19-95). Gender distribution was as follows: 552 (55.2%) women and 448 (44.8%) men. ERCP indications in this study were as follows: choledocholithiasis, malignant bile duct obstruction, odysphincter dysfunction (ODS), post-operative bile leakage, hepatic hydatid cyst rupture into the biliary tract and bile duct stenosis. Eight hundred and seventy-one (87.1%) patients had common bile duct stones, 30 (3%) pancreatic head tumour, 22 (2.2%) common bile duct tumour and 20 (2%) cholestasis due to papilla tumour and/or obstructive icterus. Twenty-two (2.2%) patients were treated for sphincter dysfunction (ODS) of Oddi. ERCP was performed in 12 (1.2%) patients with the diagnosis of bile leakage after liver hydatid surgery, 10 (1%) after gall bladder surgery and 8 (0.8%) with the diagnosis of biliary tract stenosis after gall bladder surgery. ERCP was performed in 5 (0.5%) patients due to biliary tract obstruction as a result of rupture of hydatid liver cyst into the biliary tract. Successful cannulation was achieved in 1000 patients listed. Ninety-seven patients who were included in the ERCP procedure but could not be cannulated were not included in the study. Endoscopic sphincterotomy was performed on all patients in the ERCP procedure. In patients with choledochal stones, stone extraction from the common bile duct and/or plastic stent placement in the common bile duct was added. Plastic stent was placed in the common bile duct in patients with pancreatic head tumour, common bile duct tumour, bile duct leakage and common choledochal stenosis. Endoscopic biopsy was taken from all patients with suspected papillary tumour. The processing time varied between 15 and 90 min. The overall complication rate was 17.4%. After ERCP, 93 patients developed amylasaemia that did not require treatment, while 50 patients were diagnosed with clinical and laboratory acute pancreatitis. Intraoperative bleeding, which did not require blood transfusion and could be controlled with adrenaline injection and/or balloon pressure, developed in 10 patients. In one patient, basket and stone were stuck in the papilla during stone extraction. There was no operative mortality.

Conclusion

ERCP is a complex procedure that uses special equipment and must be performed by experienced specialists. To increase the reliability of the ERCP procedure, it is necessary to determine the risk factors for ERCP complications very well. Unnecessary ERCP should be avoided. ERCP should not be performed, especially in patients with low probability of stone or stricture, patients with normal bilirubin and patients who do not show other signs of biliary disease. The use of non-invasive imaging methods as much as possible instead of diagnostic ERCP will reduce the complications associated with ERCP.

Efficacy and Safety of Exploring Deeper Sections of the Infrapapillary Area of the Duodenum by Using Sedative Esophagogastroduodenoscopy

Background

Using conventional esophagogastroduodenoscopy (EGD) to evaluate the infrapapillary area is not feasible. The use of sedative EGD may enable endoscopists to investigate the infrapapillary condition of the duodenum. In this study, we aimed to evaluate lesions in the infrapapillary regions by using sedative EGD.

Methods

In this retrospective observational study, we used the data of patients who underwent sedative EGD examinations at a tertiary hospital in southern Taiwan. The endoscopists evaluated the esophagus, stomach, and proximal duodenum and then attempted to explore the infrapapillary portion of the duodenum as deeply as possible. We assessed the success rate for the exploration of infrapapillary areas. Furthermore, we analyzed specific clinical findings of sedative EGD examination.

Results

In total, 2973 patients underwent sedative EGD between November 1, 2010, and December 31, 2011. For 2632 of these patients, it was their first sedative EGD examination. In 2511 patients (95.4%), the exploration of the infrapapillary areas was successful. In approximately 10% of the patients, specific findings were detected over the infrapapillary region, and 7 of these patients exhibited clinically significant findings (i.e., gallbladder cancer with metastasis, periampullary Vater adenoma, natural killer cell enteropathy, villous adenoma with moderate dysplasia, infrapapillary duodenal adenoma with dysplasia, duodenal perforation with tumor-like formation, and follicular lymphoma). No patient experienced minor or major adverse reactions during the sedative EGD procedure.

Conclusions

The current study provided evidence that sedative EGD examination enables a safe, comfortable, and effective endoscopic examination of deeper sections of the duodenum to evaluate the papillary and infrapapillary regions.

Large Hepatic Subcapsular Hematoma Following Endoscopic Retrograde Cholangiopancreatography: A Case Report

For decades, endoscopic retrograde cholangiopancreatography (ERCP) has been the cornerstone in the treatment of several biliopancreatic diseases. Although it is a relatively safe procedure, there are certain hazards involved. Hepatic subcapsular hematoma (HSH) is an uncommon complication of ERCP, with only a few cases reported in the literature to date. We present here a case of large HSH that developed 48 hours after an otherwise uneventful ERCP for choledocholithiasis. After being apparently well for the first two days post-ERCP, the patient began to develop abdominal pain and restlessness associated with hemodynamic instability and a decline in hemoglobin levels. Computed tomography (CT) confirmed the presence of a large HSH. The patient was managed nonsurgically with vascular angioembolization followed by ultrasound-guided percutaneous catheter drainage of hematoma. This case highlights the necessity of increasing awareness about this complication in order to aid in early diagnosis and management.

Safety and efficacy of different techniques in difficult biliary cannulation at endoscopic retrograde cholangiopancreatography

BACKGROUND

Adverse events (AEs) are commonly seen at endoscopic retrograde cholangiopancreatography (ERCP) during difficult biliary cannulation (DBC). Therefore, attaining the right technique is essential to have improved outcomes.

METHODS

Patients who had DBC over a 3-year period were assessed for outcomes. The protocol included double guidewire (DGW) technique, wire-guided cannulation (WGC) after pancreatic stent, precut sphincterotomy/fistulotomy, and EUS-guided rendezvous (RV). The success of various techniques and AE was studied.

RESULTS

As per available case analysis, a total of 3680 patient details were assessed out of which DBC was noted in 471 (12.8%) patients with a mean (SD) age of 51.5 (17.4) years; majority being 330 (70.1%) males. Most patients underwent precut sphincterotomy 230 (48.8%); however, it was not successful in the first attempt in 10 (2.1%) patients with the success rate of 220 (95.6%). The success rate of DGW cannulation was 120 (95.2%), WGC after pancreatic stent was 64 (94.1%), EUS-RV was 34 (97.1%), and wire-guided repeat ERCP after 48 h was 10 (98.3%). AEs were noted in 52 (11.1%) patients. After precut, 32 (13.9%) patients developed AE out of which post-ERCP pancreatitis was noted in 20 (8.7%). Twenty-three patients had failed biliary access after all methods and 20 (86.9%) of those received successful percutaneous transhepatic biliary drainage.

CONCLUSION

Repeat ERCP after 48 h and EUS-RV appear prudent for DBC. Precut remains one of the preferred choices for most endoscopists when there is no entrance to PD. Further utilizing an algorithmic approach can contribute to higher success rates without compromising safety.

Successful Removal of a Biliary Stent in the Jejunum Using Double-Balloon Enteroscopy

Background:

Plastic biliary stent placement has been widely used as a safe approach for the management of hilar neoplasms or the dilation of benign biliary obstruction. Despite the complexity of this procedure, this approach is followed by a few complications. The incidence rate of stent migration is about 10%. In a majority of cases, the migrated stents are retained within the gastrointestinal tract and pass through the intestine with no complication or need for medical intervention.

Case Report:

In this paper, we described the case of the migrated biliary stent with prolonged abdominal pain, which was removed successfully by using double-balloon.

Conclusion:

In the case of patient with prolonged abdominal pain and previous history of biliary stent placement, migration of stent should be considered as differential diagnosis and Double-Balloon Enteroscopy can be a safe approach in those cases.

Endoscopic retrograde cholangiopancreatography: Current practice and future research

Endoscopic retrograde cholangiopancreatography (ERCP) has evolved from a primarily diagnostic to therapeutic procedure in hepatobiliary and pancreatic disease. Most commonly, ERCPs are performed for choledocholithiasis with or without cholangitis, but improvements in technology and technique have allowed for management of pancreatic duct stones, benign and malignant strictures, and bile and pancreatic leaks. As an example of necessity driving innovation, the new disposable duodenoscopes have been introduced into practice. With the advantage of eliminating transmissible infections, they represent a paradigm shift in quality improvement within ERCP. With procedures becoming more complicated, the necessity for anesthesia involvement and safety of propofol use and general anesthesia has become better defined. The improvements in endoscopic ultrasound (EUS) have allowed for direct bile duct access and EUS facilitated bile duct access for ERCP. In patients with surgically altered anatomy, selective cannulation can be performed with overtube-assisted enteroscopy, laparoscopic surgery assistance, or the EUS-directed transgastric ERCP. Cholangioscopy and pancreatoscopy use has become ubiquitous with defined indications for large bile duct stones, indeterminate strictures, and hepatobiliary and pancreatic neoplasia. This review summarizes the recent advances in infection prevention, quality improvement, pancreaticobiliary access, and management of hepatobiliary and pancreatic diseases. Where appropriate, future research directions are included in each section.

Cholangioscopy-assisted guidewire placement in a malignant biliary stricture: A case report

BACKGROUND

Cholangioscopy has been described in case reports and series to facilitate guidewire placement in difficult benign biliary strictures. Specifically, it has been infrequently used in difficult benign anastomotic liver transplant biliary strictures to visualize the stricture orifice for guidewire placement. Here we describe a case of guidewire placement through a difficult malignant biliary stricture using single operator cholangioscopy.

CASE SUMMARY

A 74-year-old female presented with jaundice and weight loss. Endoscopic ultrasound and endoscopic retrograde cholangiopancreatography (ERCP) by other endoscopists demonstrated pancreatic adenocarcinoma with a dilated cystic duct (CD) and proximal common bile duct (CBD). The associated distal CBD stricture was dilated and stented with a plastic stent. However she subsequently developed cholangitis, prompting referral for a repeat ERCP. The stent was found to have migrated distally to the confluence of the dilated CD and CBD stricture. Despite using multiple hydrophilic guidewires, the stricture could not be traversed due to preferential wire passage into the dilated CD. SpyGlass DS (Boston Scientific Corp, Marlborough, MA, United States) was then used to visualize the orifices of the CD and CBD stenosis, enabling the guidewire to be placed directly through the stricture into the proximal CBD. A WallFlex covered metal stent (Boston Scientific Corp, Marlborough, MA, United States) was successfully placed, resulting in resolution of her cholangitis.

CONCLUSION

To our knowledge, this is one of the first cases to describe successful cholangioscopic guidewire placement for malignant biliary strictures.
