Emergency endoscopic retrograde cholangiopancreatography in critically ill patients

Endoscopic retrograde cholangiopancreatography (ERCP) in critically ill patients is safe and effective when performed in the endoscopy suite

Background and study aims  Critically ill patients may require endoscopic retrograde cholangiopancreatography (ERCP) but performing ERCP in the intensive care unit (ICU) poses logistic and technical challenges. There are no data on ICU patients undergoing ERCP in the endoscopy suite. The primary aim of this study was to report outcomes, including safety, when ERCP in critically ill patients is performed in the endoscopy suite. Patients and methods  We queried our institutional endoscopy database to identify all ICU patients who underwent ERCP at a single academic medical center from 04/01/2010 to 11/30/2017. Only patients admitted to an ICU prior to ERCP were included. Results  Of 7,218 ERCPs performed during the study period, 260 ERCPs (3.6 %) were performed in 231 ICU patients (mean age 61y; 53 % male); nearly all ICU patient ERCPs (n = 258; 99 %) occurred in the endoscopy suite. ERCP indications included cholangitis (50 %), post-liver transplant cholestasis (15 %), and bile leak (10 %). All ERCPs were performed with anesthesiology, most with general anesthesia (60 %) and in the prone position (60 %). Most patients (73 %) had sepsis. Prior to ERCP, 17 % of patients required vasopressors; vasopressors were begun during ERCP in 4 %. The cannulation success rate was 95 % (94 % in native papillae). Adverse events occurred in 9 % (n = 23) of cases with post-ERCP pancreatitis most common. No patients died during or within 24 hours of ERCP. Mortality at 30 days was 16 %, all attributed to underlying disease. Conclusions  When advanced ventilatory and hemodynamic support is available, critically ill patients can safely and effectively undergo ERCP in the endoscopy suite.

Emergency endoscopic retrograde cholangiopancreatography in critically ill patients is a safe and effective procedure

Emergency ERCP may be required in patients with severe cholangitis who rapidly deteriorate with multi-organ dysfunction and who cannot wait until the next available elective list. A significant proportion of patients require ventilatory and inotropic support. We describe our experience on the outcome of emergency ERCP in this cohort of critically ill patients. Medical records of cases undergoing ERCP between November 2008 and November 2011 were retrospectively reviewed. Patients who were in intensive care unit or required general anaesthesia due to haemodynamic compromise at the time of ERCP were included. Total of 2237 ERCPs were performed during this period, of which 36 (2%) emergency ERCP's were performed in 33 patients. The median age was 79 years. All procedures were performed under general anaesthesia in emergency operating room. In 27/36 procedures (75%), the patients required inotropes. Indications included cholangitis (78%), pancreatitis (14%) and post-operative bile leak (8%). Biliary cannulation was achieved in 100% of cases. Endoscopic findings included CBD stones (64%), CBD stones and an additional pathology (8%), bile leak (8%), CBD stricture (5%), Mirizzi's (3%) and blocked plastic stent (3%). In 23/36 (64%) procedures a stent was inserted. In 11/36 (30%) procedures a balloon trawl was sufficient to clear the bile duct. Thirty-day mortality was 25%. Although the 30-day mortality remains high due to multi-organ failure, ERCP is successful and effective in the majority of patients and results in a good outcome for this cohort of critically ill patients, in whom the prognosis is inevitably poor without emergency biliary drainage.

Diagnostic bedside EUS in the intensive care unit: a single-center experience

BACKGROUND

The knowledge of bedside diagnostic EUS in critically ill patients is limited.

OBJECTIVE

To investigate the indications, feasibility, safety, and clinical utility of diagnostic EUS in the intensive care unit (ICU).

DESIGN

Retrospective.

SETTING

Tertiary-care referral teaching hospital.

PATIENTS

All consecutive patients who had EUS done in the ICU within a 6-year period.

INTERVENTION

Bedside EUS and EUS-guided FNA.

MAIN OUTCOME MEASUREMENTS

EUS indications, complications, and impact on management.

RESULTS

A total of 64 EUS procedures were performed in 63 patients (38 men, 25 women; age range 27-78 years); 1 patient underwent 2 separate EUS procedures. EUS was performed while the patients were mechanically ventilated in 70% (45/64) of cases. Indications for EUS included jaundice (n = 24), mass of unknown etiology (n = 25), unexplained pancreatitis (n = 7), and staging of known cancer (n = 3). In 5 cases, EUS was used as an alternative to other imaging modalities because of morbid obesity (n = 3) or contraindication to intravenous contrast material (n = 2). Complications included reversible oxygen desaturation (n = 4), nonsustained ventricular tachycardia (n = 1), and transient hypotension (n = 1). Overall, EUS influenced management in 97% (62/64) of cases.

LIMITATIONS

Retrospective, single-center study.

CONCLUSION

ICU-based EUS can be performed with few intraprocedural complications and can be a valuable diagnostic modality in the ICU setting. It appears to be particularly useful for determining the etiology of jaundice, masses of unknown etiology, and pancreatitis. It may have particular value as a diagnostic technique on selected patients with unstaged cancer and when morbid obesity or the inability to use intravenous contrast material precludes the use of other imaging modalities in the critically ill patient.

The role of ERCP in patients with pancreatico-biliary problems in the setting of hematopoietic stem cell transplant

BACKGROUND

Patients undergoing hematopoietic stem cell transplant may develop pancreatico-biliary complications that may require ERCP. Due to their immunocompromised state, these patients may be at higher risk of procedure-related complications.

OBJECTIVE

To determine the role of ERCP in the diagnosis and treatment of patients who have undergone hematopoietic stem cell transplant and the patients' clinical outcomes.

DESIGN

Retrospective analysis of patients with hematopoietic stem cell transplant who underwent ERCP from 1997 to 2004 evaluating ERCP indications, diagnosis, therapeutic interventions, and complications.

SETTING

Tertiary referral center.

RESULTS

Of the 16 patients identified, 9 were female, 15 had had allogeneic hematopoietic stem cell transplant, and 1 had an autologous hematopoietic stem cell transplant. Twenty-six ERCP procedures were performed in the 16 patients. Index ERCP findings included: extra hepatic bile duct obstruction in 12 patients, of which 7 had biliary lithiasis. Ampullary obstruction due to infiltration from graft versus host disease was seen in 3 of 12 patients, benign bile duct stricture in 1 of 12, and ampullary obstruction in the setting of a peri-ampullary diverticulum in 1 of 12. Index ERCP findings in the remaining 4 patients included: intrahepatic bile duct compression due to metastatic disease in 1 of 16 patients, bile duct leak in 1 of 16, pancreatic duct stone in 1 of 16, and normal ERCP in 1 of 16. Complications occurred in 4 patients: mild pancreatitis (1), mild bleeding (1), cholangitis due to late stent occlusion (1), and intermittent bradycardia (1). There were no ERCP-related deaths.

LIMITATIONS

Single-center study.

CONCLUSION

In patients with hematopoietic stem cell transplant, bile duct lithiasis was the most common finding at ERCP, followed by obstructive ampullary tissue infiltration due to graft versus host disease. ERCP yielded clinically relevant information in this particular group of patients.

Endoscopic retrograde cholangiopancreatography should no longer be used as a diagnostic test: the case against

Endoscopic retrograde cholangiopancreatography has been used successfully in diagnosis of pancreatico-biliary diseases. Over the past decade, there have been tremendous developments in radiological technologies which have led to the emergence of new and less invasive modalities like endoscopic ultrasound and spiral computed tomography and magnetic resonance cholangiopancreatography. Understandably, the usefulness of diagnostic endoscopic retrograde cholangiopancreatography is being questioned primarily because of its potential attendant complications. Therefore, this controversial question needs to be debated in the gastroenterology community. In this article, we compare the efficacy of newer diagnostic tools with existing "gold standard" modality--endoscopic retrograde cholangiopancreatography, and put forward our arguments in favour of a continuing role for endoscopic retrograde cholangiopancreatography as a diagnostic tool in certain circumstances.
