Outpatient therapeutic ERCP with endobiliary stent placement for malignant common bile duct obstruction

A Prospective, Randomized Comparison of Duodenoscope Reprocessing Surveillance Methods

Duodenoscope use in healthcare facilities has been associated with transmission of multidrug resistant pathogens between patients. To assist healthcare facilities in monitoring the quality of their duodenoscope reprocessing procedures and limit patient risk of infection, the Centers for Disease Control and Prevention (CDC) deployed voluntary interim duodenoscope sampling and culturing surveillance protocols in 2015. Though the interim methods were widely adopted, alternative surveillance protocols were developed and implemented at individual institutions. Here, we compared two sampling methods-the 2015 CDC interim protocol and an alternative protocol developed by the University of Wisconsin Hospitals and Clinics (UWHC). We hypothesized that the UWHC protocol would detect a higher incidence of bacterial contamination from reprocessed duodenoscopes. A total of 248 sampling events were performed at UWHC. The CDC protocol (n = 129 sampling events) required culturing samples collected from each duodenoscope after brushing its terminal end and flushing its lumen with sterile water. The UWHC protocol (n = 119 sampling events) required culturing samples collected from each duodenoscope after swabbing its elevator, immersing its terminal end into broth and flushing its lumen with saline. With the CDC method, 8.53% (n = 11) of the duodenoscopes sampled were positive for bacterial growth with 15 isolates recovered. Using the UWHC method, 15.13% (n = 18) of cultures were positive for bacterial growth with 20 isolates recovered. The relative risk of identifying a contaminated duodenoscope using the CDC interim method, however, was not different than when using the UWHC protocol. Mean processing time (27.35 and 5.11 minutes, p < 0.001) and total cost per sample event ($17.87 and $15.04) were lower using the UWHC method. As the UWHC protocol provides similar detection rates as the CDC protocol, the UWHC method is useful, provided the shorter processing time and lower cost to perform.

Therapeutic Endoscopy Can Be Performed Safely in an Ambulatory Surgical Center: A Multicenter, Prospective Study

Background. Even amongst experienced endoscopists, endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound with fine needle aspiration (EUS-FNA) carry a potential risk for complications. These procedures are typically performed in a hospital-based endoscopy unit with general anesthesia. Aims. The goal of our study was to evaluate the feasibility of ERCP and EUS-FNA in an ambulatory surgical center (ASC). Methods. From June to November of 2014, we prospectively enrolled consecutive subjects undergoing ERCP and/or EUS-FNA in an ASC. An anesthesiologist, who was not involved in our study group, screened all subjects prior to their scheduled procedure. In order to monitor for adverse events (AE), all subjects received a telephone call at day 1 and 30 days after procedure. Results. 375 subjects (98 inpatients and 277 from an ASC) were enrolled. In the total population, a high proportion of subjects underwent procedures for neoplasms (21 (23.3%) inpatients versus 44 (17.1%) from an ASC) and for sphincter of Oddi dysfunction (SOD) (27 (27.5%) versus 48 (17.3%)) and had the American Society for Anesthesiologists (ASA) class ≥III (75 (76.5%) versus 140 (50.5%)) and high-risk features (17 (17.3%) versus 75 (27.1%)). Overall ERCP-related AE (10 (13.2%) versus 12 (7.5%), p = 0.2), pancreatitis (7 (9.2%) versus 11 (6.9%), p = 0.6), and hemorrhage (3.9% versus 0.6%, p = 0.25) were not different between inpatients and ASC subjects. There was also no difference between inpatients and ASC subjects' EUS-related AE (1 (4.5%) versus 4 (3.4%), p = 0.6), pancreatitis (1 (4.5%) versus 3 (2.6%), p = 0.2), and hemorrhage (0% versus 1 (0.9%), p = 0.9). Conclusions. ERCP and EUS can be performed in a higher risk population under the supervision of anesthesia in ASCs. Overall, the AE are equivalent between inpatients and ASC subjects.

Otaru consensus on biliary stenting for unresectable malignant hilar biliary obstruction

Biliary stenting for unresectable malignant biliary strictures is widely accepted and is routinely done as an effective palliation therapy. However, a consensus among experts is still far from being reached on the selection of stents, placement procedures etc. In 2012, the European Society of Gastrointestinal Endoscopy reported guidelines for biliary stenting. At the Endoscopic Forum Japan 2012, a consensus meeting was held to examine seven statements that had been prepared based on these guidelines.Herein, we report the contents and the results of the examination of three of these statements on biliary stenting for hilar strictures.

Is outpatient ERCP suitable, feasible, and safe? The experience of a Spanish community hospital

BACKGROUND

We wanted to evaluate the safety of outpatient endoscopic retrograde cholangiopancreatography (ERCP). The follow-up of an ERCP outpatient during a short observation period could be a feasible and safe approach.

METHODS

To evaluate the safety of outpatient ERCP, we assessed the rate of post-ERCP complications found and missed during a 6-h observation period after therapeutic ERCP.

RESULTS

We performed 236 ERCPs on an outpatient basis, with a failure rate of 3.7% but with an overall completion rate for the intended treatment of 90.7%. Seventy-eight percent of the ERCPs were primarily therapeutic. The age of the patients was 63.9 years and 61.9% were females. One hundred seventy-seven (74.5%) patients were discharged from the hospital after the observation period. Thirty-three (14.1%) patients were admitted without further delay due to unexpected ERCP findings or for early detection of complications. Twenty-seven (11.4%) patients had a prolonged hospital stay because of complications during the observation period. Just two patients previously discharged developed later complications: cholangitis and pancreatitis (0.84% of the ERCPs and 7.4% of the overall complications). There were 27 ERCP complications (12.1%). Of the overall complications, 29.6% were diagnosed very early after the procedure and 62.9% were diagnosed during the observation period. 8.9% out of the 12.1% of the ERCP complications were mild to moderate. There was no mortality.

CONCLUSION

Twenty-five (92.6%) of ERCP complications occurred during the first 6 h, making the use of this short observation period safe for an early discharge. The evolution of the patients who developed delayed complications was unremarkable. Whenever outpatient ERCP is feasible, it should be done to help cut costs.

ERCP as an outpatient treatment: a review

BACKGROUND

ERCP on an outpatient basis could be as safe as on an inpatient basis and may also reduce medical costs.

OBJECTIVE

To review the available literature to determine the safety of an ERCP performed on an outpatient basis.

DESIGN

A review of the published literature was performed by searching PubMed, the Cochrane Library, EMBASE, and the Web of Science.

PATIENTS

Patients who were undergoing an ERCP.

INTERVENTIONS

An ERCP on an inpatient or outpatient basis.

MAIN OUTCOME MEASUREMENTS

Patient and treatment characteristics, complications, and prolonged hospital admissions and readmissions.

RESULTS

Eleven studies were included in this review, of which 5 were comparative studies, 5 were prospective studies, and 1 was a retrospective study. In these series, a total of 2483 patients underwent an ERCP on an outpatient basis and 2320 patients were admitted overnight after an ERCP. Complications were seen in 184 of 2483 outpatients (7%), of which 72% of complications (107/149) presented within 2 to 6 hours, 10% (15/149) within 6 to 24 hours, and 18% (27/149) more than 24 hours after the ERCP. Three percent of the inpatients (82/2320) developed a complication, of which 95% of complications (78/82) presented within 24 hours and 5% (4/82) presented more than 24 hours after the ERCP. A prolonged hospital stay after an ERCP was indicated in 6% of the designated outpatients (148/2483), whereas 3% of outpatients (74/2149) and <1% of inpatients (4/2320) were readmitted after discharge.

LIMITATIONS

Limited data available.

CONCLUSIONS

This review shows that, with a selective policy, an ERCP on an outpatient basis seems as safe as when performed on an inpatient basis.

Palliation of malignant obstructive jaundice

Palliation of obstructive jaundice can be achieved in most patients using various approaches. The method chosen should be individualized to the patient and based upon performance status, patient preferences, and available expertise. The best approach ideally should be determined by a multi-discipline approach with endoscopists, interventional radiologists, oncologists, and surgeons.

Efficacy and safety of therapeutic ERCP in patients 90 years of age and older

BACKGROUND

Therapeutic ERCP has an established role in the treatment of pancreatobiliary diseases, but little information is available on the outcomes of this procedure in patients 90 years of age and older.

OBJECTIVE

To evaluate the efficacy and the safety of therapeutic ERCP in an extremely elderly cohort.

DESIGN

Retrospective study.

SETTING

Two Greek cohorts of patients > or =90 and 70 to 89 years of age who underwent therapeutic ERCPs.

PATIENTS

Sixty-three patients aged 90 years and older (group A) and 350 patients 70 to 89 years of age (group B).

INTERVENTIONS

A retrospective review of therapeutic ERCPs was performed between 1994 and 2000 on both groups, identified by using a database linked to the endoscopy reporting system in our department.

MAIN OUTCOME MEASUREMENTS

Efficacy and safety of therapeutic ERCPs. Concomitant diseases, complications, and outcome were also evaluated.

RESULTS

Group A patients had a higher incidence of concomitant diseases than group B patients (100% vs 72.8%, respectively). The rate of post-ERCP early complications was low in both groups: 6.3% in group A and 8.4% in group B. The frequency of ERCP-related mortality was 1.6% (1 patient) in group A and 0.6% (2 patients) in group B. Group A required endoscopic sessions for stone clearance and mechanical lithotripsy more frequently than group B (20.6% vs 11.4% and 17.5% vs 10.3%, respectively). No patient in either group experienced subjective deterioration in mental status, and the 3 patients who died required ventilatory support before death. Late complications occurred in 2.3% of patients in group B.

CONCLUSIONS

Therapeutic ERCP is safe and effective for the treatment of pancreatobiliary diseases in extremely elderly patients, and advanced age per se should not impinge on decisions relating to its use.

Expandable metal biliary stents before pancreaticoduodenectomy for pancreatic cancer: a Monte-Carlo decision analysis

BACKGROUND & AIMS

Endoscopic placement of plastic or self-expandable metal biliary stents (SEMS) relieves obstructive jaundice from pancreatic cancer. Short-length, distally placed SEMS do not preclude subsequent pancreaticoduodenectomy. We sought to determine whether SEMS placement in patients whose surgical status is uncertain is cost-effective for management of obstructive jaundice.

METHODS

A Markov model was constructed to evaluate costs and outcomes associated with endoscopic biliary stenting for obstructive jaundice. Strategies evaluated were: (1) initial plastic stent with plastic stents for subsequent occlusions in nonsurgical candidates after staging (plastic followed-up by [f/u] plastic), (2) initial plastic with subsequent SEMS (plastic f/u metal), (3) initial short-length SEMS with subsequent plastic (metal f/u plastic), and (4) initial short-length SEMS with subsequent expandable metal stent (metal f/u metal). Published stent occlusion rates, ERCP complication rates and outcomes, cholangitis rates and outcomes, pancreatic cancer mortality rates, and Whipple complication rates were used. Costs were based on 2004 Medicare standard allowable charges and were accrued until all patients reached an absorbing health state (death or pancreaticoduodenectomy) or 24 cycles (24 mo) ended.

RESULTS

Average costs per patient from Monte Carlo simulation were: (1) metal f/u metal, $19,935; (2) plastic f/u metal, 20,157 dollars; (3) metal f/u plastic, 20,871 dollars; and (4) plastic f/u plastic, 20,878 dollars. For initial plastic stents to be preferred over short-length metal stents, 70% or more of pancreatic cancers would need to be potentially resectable by pancreaticoduodenectomy.

CONCLUSIONS

In patients undergoing ERCP before definitive cancer staging, short-length SEMS is the preferred initial cost-minimizing strategy.

Outcome following endoscopic transmural drainage of pancreatic fluid collections in outpatients

OBJECTIVE

To evaluate the performance of endoscopic transmural drainage of pancreatic fluid collections (PFCs) in outpatients.

PATIENTS AND METHODS

We retrospectively reviewed 19 consecutive outpatient cases in 18 patients who underwent attempted endoscopic transmural drainage of PFCs by a single endoscopist at the Mayo Clinic in Rochester, MN, over a 5-year period (October 1998 to October 2003). All drainages were performed without EUS-guided entry, using an aspiration needle and no cautery. Two 10-Fr stents were placed after dilation of the entry site.

RESULTS

The study group consisted of 12 men and 6 women (median age, 48 years; range, 28-79 years), with 14 cases of pseudocysts and 5 cases of pancreatic necrosis. Transmural drainage approaches included 13 transgastric, 5 transduodenal, and 1 combined transgastric/transpapillary. Drainage was established in 16 of 19 (84%) cases. Hospitalization was noted in 6 of 19 (32%) cases, with median hospitalization duration of 1.5 days (range, 1-19 days). Three patients were hospitalized for overnight observation only. In all instances, the decision to hospitalize was made while the patient was still in recovery. No deaths occurred. Follow-up imaging was available in 15 of 16 (94%) cases in which drainage was established, demonstrating PFC resolution in all 15.

CONCLUSIONS

Endoscopic transmural drainage of PFCs can be performed safely and effectively in selected outpatients. It is our opinion that outpatient drainage of PFCs be considered only by experienced therapeutic endoscopists with readily available inpatient facilities. Future studies should seek to identify predictors of hospitalization and address cost-effectiveness.

A colangiopancreatografia retrógrada endoscópica pode ser realizada com segurança em caráter ambulatorial

RACIONAL: A colangiopancreatografia endoscópica retrógrada é técnica efetiva no manejo das doenças biliopancreáticas. A segurança da realização do exame em ambulatório tem sido alvo de estudo. OBJETIVO: Avaliar a segurança da realização da colangiopancreatografia endoscópica retrógrada em ambulatório e descrever as complicações do exame. CASUÍSTICA E MÉTODO: Acompanharam-se, prospectivamente, pacientes ambulatoriais encaminhados para colangiopancreatografia endoscópica retrógrada durante o período de 2001 a 2003. Complicações foram definidas segundo critérios de consenso, incluindo todos os efeitos adversos relacionados ao exame. RESULTADOS: Foram incluídas 195 colangiopancreatografias endoscópicas retrógradas, 79 (40,5%) diagnósticas e 116 (59,5%) terapêuticas. O grupo incluiu 112 mulheres, com média de idade de 51 anos (±18,9). Os diagnósticos encontrados mais freqüentemente foram: cálculo biliar (30,2%), estenose benigna (13,8%), neoplasia (10,2%) e pancreatite crônica (10,2%). Obteve-se sucesso em 88,6% dos exames diagnósticos e 78,5% dos terapêuticos. Dos 195 pacientes, 10 (5,1%) necessitaram de observação, dentre os quais 7 (3,6%) foram internados, (2 pacientes com pancreatite aguda, 2 com perfurações, 1 com hemorragia, 1 com complicação cardiorespiratória e 1 com febre). Dos 188 casos liberados após o exame, 8 (4,2%) foram readmitidos (1 pancreatite aguda, 1 hemorragia, 1 perfuração, 3 colangite, 2 dor abdominal). Ao comparar o grupo das complicações identificadas imediatamente contra o segundo, não se encontrou diferença estatisticamente significante quanto à idade, sexo, diagnóstico e/ou grau de dificuldade do exame. CONCLUSÃO: O tamanho da amostra e os resultados negativos da análise estatística impediram a determinação de fatores de risco, independentes para complicações pós- colangiopancreatografia endoscópica retrógrada. Contudo, não houve nenhum óbito ou complicações com má evolução nos pacientes inicialmente liberados, confirmando a segurança na realização da colangiopancreatografia endoscópica retrógrada em ambulatório.

Outpatients undergoing therapeutic endoscopic retrograde cholangiopancreatography: six-hour versus overnight observation

BACKGROUND AND AIM

The purpose of the present retrospective study was to compare the proportion of post-endoscopic retrograde cholangiopancreatography (ERCP) complications detected with 6-h observation followed by same-day discharge (SDD) versus overnight observation (OO) after therapeutic ERCP.

METHODS

There were 134 outpatients in the SDD group and 178 outpatients in the OO group. The SDD group was discharged after a 6-h observation while the OO group was discharged after overnight observation. Patients in the SDD group were admitted from the recovery room for evaluation if they had systolic blood pressure (BP) < 100 mmHg, pulse > 100/min, temperature > 37.5 degrees C, or post-procedure abdominal pain. The primary outcome of the present study was the proportion of post-ERCP complications detected within the observational period between the SDD group and the OO group.

RESULTS

The post-ERCP complication rate of therapeutic ERCP in the SDD and OO groups were 9.7% and 9.6%, respectively (P = 0.964). Eleven patients (8.2%) in the SDD group and 13 patients (7.3%) in the OO group were found to have post-ERCP complications within the observation period. There was no significant difference in the proportion of post-ERCP complications detected within the observational period between the two groups (P = 0.672).

CONCLUSION

Outpatient therapeutic ERCP with observation of 6 h can detect the same proportion of patients with post-ERCP complications as overnight observation.

Risk factors for complications after performance of ERCP

BACKGROUND

ERCP has become widely available for the diagnosis and treatment of benign and malignant pancreaticobiliary diseases. In this prospective study, the overall complication rate and risk factors for diagnostic and therapeutic ERCP were identified.

METHODS

Data were collected prospectively on patient characteristics and endoscopic techniques from 1223 ERCPs performed at a single referral center and entered into a database. Univariate and multivariate analyses were used to identify risk factors for ERCP-associated complications.

RESULTS

Of 1223 ERCPs performed, 554 (45.3%) were diagnostic and 667 (54.7%) therapeutic. The overall complication rate was 11.2%. Post-ERCP pancreatitis was the most common (7.2%) and in 93% of cases was self-limiting, requiring only conservative treatment. Bleeding occurred in 10 patients (0.8%) and was related to a therapeutic procedure in all cases. Nine patients had cholangitis develop, most cases being secondary to incomplete drainage. There was one perforation (0.08%). All other complications totaled 1.5%. Variables derived from cannulation technique associated with an increased risk for post-ERCP pancreatitis were precut access papillotomy (20%), multiple cannulation attempts (14.9%), sphincterotome use to achieve cannulation (13.1%), pancreatic duct manipulation (13%), multiple pancreatic injections (12.3%), guidewire use to achieve cannulation (10.2%), and the extent of pancreatic duct opacification (10%). Patient characteristics associated with an increased risk of pancreatitis were sphincter of Oddi dysfunction (21.7%) documented by manometry, previous ERCP-related pancreatitis (19%), and recurrent pancreatitis (16.2%). Pain during the procedure was an important indicator of an increased risk of post-ERCP pancreatitis (27%). Independent risk factors for post-ERCP pancreatitis were identified as a history of recurrent pancreatitis, previous ERCP-related pancreatitis, multiple cannulation attempts, pancreatic brush cytology, and pain during the procedure.

CONCLUSIONS

The most frequent ERCP-related complication was pancreatitis, which was mild in the majority of patients. The frequency of post-ERCP pancreatitis was similar for both diagnostic and therapeutic procedures. Bleeding was rare and mostly associated with sphincterotomy. Other complications such as cholangitis and perforation were rare. Specific patient- and technique-related characteristics that can increase the risk of post-ERCP complications were identified.

[Endoscopic treatment of obstructive jaundice at a second level national health system hospital]

BACKGROUND AND AIMS

The difficulty of performing endoscopic retrograde cholangiopancreatography (ERCP) in our patients in the reference hospitals within a few days of diagnosis of obstructive jaundice led us to perform this technique in our center. We expected to perform a small number of ERCP annually. We analyzed the success rate of initial biliary drainage and the complications of this procedure.

PATIENTS AND METHODS

We performed a retrospective study. From 1997-1999 we carried out 240 ERCP. In 128 patients, 140 ERCP were performed for obstructive jaundice (58,3%). The final diagnosis was choledocholithiasis in 69 patients (54%), tumors in 35 (27%), dilatation of the biliary tract without obstruction at cholangiography in 21 (17%) and benign stenosis of the biliary tract in 3 (2%).

RESULTS

The mean procedure time for ERCP was 5.26 ( 2.8) days. Cholangiography was successfully performed in 117 patients (91.4%). Effective therapeutic endoscopy was performed in 111 patients (86.7%). Jaundice was resolved in 62 patients (90%) with choledocholithiasis, 55 (80%) by stone removal and in 7 (10%) by prosthesis. Resolution was also achieved in 25 (71.5%) tumors, mainly by prosthesis, and in 100% of patients with benign stenosis. In all patients with dilatation of the biliary tract without obstruction, biliary sphincterotomy was performed. Complications were found in 15 patients (11.7%) and two (1.56%) died.

CONCLUSIONS

The majority of patients with obstructive jaundice can be satisfactorily treated in a center with our characteristics. However, in tumors, the figures for drainage were slightly lower than those reported in the medical literature.

Endoscopic treatment of pancreatico-biliary malignancies

Biliary obstructions, due to pancreatic cancer and cholangiocarcinoma, have an ominous prognosis. At the time of diagnosis, most patients are beyond any curative treatment. Palliative therapies, such as transhepatic biliary drainage, bypass surgery, and endoscopy, have an established role in the management of such patients. Endoscopic retrograde cholangio-pancreatography (ERCP) plays a key role, allowing diagnosis, collection of cytologic and bioptic specimens, and insertion of large-bore biliary stents. The major drawback of plastic stents is the high rate of clogging, requiring frequent stent exchange. In the 1990s, self-expanding metal stents (SEMS) were developed and randomized studies have shown their superiority over plastic stents. SEMS can be successfully used in patients with hilar tumors. Duodenal obstruction due to biliopancreatic neoplasms can also be managed endoscopically. ERCP can be performed on an outpatient basis in selected patients, reducing costs related to hospitalization. A team approach is mandatory to obtain the best results.
