Impact of cytomegalovirus on outcomes in acute severe ulcerative colitis: a retrospective observational study.

Background: Concomitant cytomegalovirus (CMV) is highly prevalent in acute severe ulcerative colitis (ASUC) but data for outcomes of CMV positivity in ASUC and the benefit of antiviral therapy remain unclear. Objectives: We aim to determine the impact of CMV positivity, and antiviral therapy, on outcomes such as colectomy-free survival, length of hospital stay and readmission rate, among hospitalized patients with ASUC. Design: This is a retrospective, multicentre study of patients admitted with ASUC. Methods: CMV positivity was diagnosed from blood CMV DNA and inpatient colonic biopsies. Background demographics and disease characteristics, clinical characteristics and outcomes during admission and long-term outcomes were obtained from electronic medical records and compared according to the presence of CMV and the use of antiviral therapy. Results: CMV was detected in 40 (24%) of 167 ASUC admissions. Previous steroid exposure was the only clinical predictor of CMV positivity on multivariate analysis. Outcomes of greater requirement for rescue therapy (60% versus 33%), longer hospital stay (14.3 versus 9.9 days) and higher readmission rates at 3 and 12 months were associated with CMV positivity. No difference was found in the rate of colectomy or colectomy-free survival. Antiviral therapy was not associated with a lower risk of colectomy but did extend the time to colectomy (126 versus 36 days). Conclusion: CMV positivity was associated with worse outcomes of need for rescue therapy, hospital stay and readmissions. Antiviral therapy was not found to reduce the risk of colectomy but did extend the time to colectomy. Further prospective studies will be required to more clearly determine its benefit in patients with concomitant CMV and ASUC.

Cytomegalovirus reactivation in acute severe ulcerative colitis Cytomegalovirus (CMV) is a highly prevalent virus that may result in concominant reactivation in patients with acute severe ulcerative colitis and potentially worsen their outcomes. Our study aims to determine the impact of presence of CMV in patients with acute severe ulcerate colitis requiring hospitalisation and its association with outcomes including risk of surgical resection of colon, length of hospital stay, readmission rate, as well as effect of outcomes amongst those treated with antivirals for CMV. Our results did not find a significant association between detection of CMV on surgical risk, though outcomes including longer hospital stays, higher readmission rate were found. Antiviral use was not associated with lower risk of surgery but was found to prolong time to surgery. Given that our study was based on retrospective data, further prospective studies will be required to examine the benefit of antiviral use in outcomes for those with concominant CMV and acute severe ulcerative colitis. We conclude from our study that while having concomitant CMV with acute severe uclerative colitis may not necessarily increase risk for surgery, patients may still have worse outcomes in other areas therefore the detection of CMV should be considered a significant and clinically relevant result.

Representation of Women in Internal Medicine Specialties in North America, the United Kingdom, and Australasia: Cardiology's Outlier Status and the Importance of Diversity.

Decades of research demonstrate the value of workplace diversity. Reports from individual countries show that women are underrepresented in internal medicine workforces. However, large pooled international studies are not available. This study investigates the current representation of women in the internal medicine workforce internationally and identifies specialties in which underrepresentation is evident. Peer-reviewed studies, government reports, and medical association reports were used to determine proportions of specialists and doctors training in internal medical specialties and in comparator surgical specialties. Data were available from Australia, Canada, England, New Zealand, the United States, Wales, Scotland, and Northern Ireland. A total of 380,263 doctors were studied, including 268,822 practicing specialist physicians (also known as attendings or consultants) and 53,226 doctors in internal medicine specialty training programs (also known as residents, fellows, advanced trainees, or specialist registrar trainees). Among practicing physician specialists, the rate of representation of women was 35% (95,195/268,822, p <0.001). Among trainees, the rate of representation of women was 43% (22,728/53,226, p <0.001). Among physician specialties evaluated, cardiology (15%, 4,152 of 27,328), gastroenterology (20%, 3,765 of 18,893), and respiratory/critical care (24%, 5,255 of 21,870) had the lowest representations of women compared with men (p <0.001 for all). Cardiology and particularly the subspecialty of interventional cardiology were clear outliers as the internal medicine specialties with the lowest representation of women at practicing specialist and trainee levels. In conclusion, this study is the largest international study of women in internal medicine specialties. It found that cardiology, gastroenterology, and respiratory/critical care specialties have the most substantial underrepresentation of women. These data are a global call to action to establish more successful strategies to provide a diverse and representative cardiology workforce.

24-hour levodopa-carbidopa intestinal gel may reduce troublesome dyskinesia in advanced Parkinson's disease.

Levodopa-carbidopa intestinal gel (LCIG) is effective for the control of motor fluctuations in Parkinson's disease (PD). The objective of this study is to report the reduction of dyskinesias after transitioning from 16 to 24-h/day LCIG infusion. From a cohort of 74 PD patients treated with LCIG for motor fluctuations, we identified 12 patients that were treated with 24-h per day infusion with the aim to control troublesome daytime dyskinesia. Clinical, demographic, dyskinesia rating scales were evaluated. Daytime dyskinesia was reduced in 75% (9/12) patients following treatment with 24-h therapy, including 7 who were compared with 16-h therapy and 2 that were transitioned from oral dopaminergic therapy to 24-h LCIG. Combining the data from all 12 subjects, troublesome dyskinesias were reduced during 24-h LCIG; UPDRS 4.1 (time spent with dyskinesias) mean change was -1.5 ± 0.75, p = 0.010 (Wilcoxon signed-rank test) and UPDRS 4.2 (functional impact of dyskinesias) mean change was -1.7 ± 0.90, p = 0.016, without changing their UPDRS part 3 "ON" scores (p = 0.138) or H&Y (p = 0.157). In 5 patients, improvement in dyskinesia occurred despite an overall increase in the total daily levodopa dose. None of the patients had worsening of dyskinesia after a median follow-up of 28 months. 24-h per day infusion of LCIG may be a useful strategy in the management of troublesome dyskinesias in PD patients with disabling dyskinesias resistant to attempts to optimise 16-hours per day therapy. We postulate that this may be due to a pharmacodynamic as opposed to pharmacokinetic mechanism.

Pediatric-to-adult Transition and Medication Adherence in Patients with Inflammatory Bowel Disease.

BACKGROUND: Medication nonadherence is common in inflammatory bowel disease and is associated with poor outcomes. There has been no study on pediatric-to-adult transition as a risk factor for nonadherence in inflammatory bowel disease, which has been demonstrated in other diseases. We aimed to assess whether transitioned (TR) patients have higher nonadherence rates than young adults (YAs) diagnosed in adulthood. METHODS: Consecutive ambulatory subjects were prospectively recruited and completed the validated Medication Adherence Reporting Scale (MARS), with the primary outcome being adherence differences between group age-matched TR and YA groups. Pediatric subjects were taken as the control group. Perceptions of medication-related necessity and concerns were assessed with the Beliefs about Medicines Questionnaire (BMQ). Nonadherers (defined as MARS ≤16) received the Inflammatory Bowel Diseases Pharmacist Adherence Counselling (IPAC) intervention and adherence change was reassessed after 6 months as a secondary outcome. RESULTS: Adherence in TR patients (n = 38, mean age 20.4, 13.2% nonadherent) was noninferior to and numerically better than YAs diagnosed in adulthood (n = 41, mean age 21.2, 24.4%). Nonadherence in the pediatric control group (n = 50, mean age 14.7) was 8.0%. YAs had significantly higher medication-related concerns (14.6 versus 11.9, P = 0.02) than the pediatric group. The IPAC intervention reduced nonadherence rates by 60% (P = 0.004). CONCLUSIONS: TR patients did not have worse adherence than YAs diagnosed in adulthood. Protective factors may include previous treatment in pediatric centers and the salient symptomatology of inflammatory bowel disease, whereas increasing concerns over medications contribute to nonadherence in YAs. Pharmacist-led counselling improves adherence in these patients.

Single-dose intra-procedural ceftriaxone during endoscopic ultrasound fine-needle aspiration of pancreatic cysts is safe and effective: results from a single tertiary center.

BACKGROUND: Endoscopic ultrasound (EUS) with fine-needle aspiration (FNA) is universally used for the investigation and diagnosis of pancreatic cystic lesions (PCL). Infectious complications following EUS-FNA of PCL are rare. Antibiotic prophylaxis to reduce the risk of infection is recommended; however, there is no consensus on the optimal regimen or route of administration. Potential advantages of a single-dose intravenous (IV) antibiotic over a prolonged oral regimen include simplicity, guaranteed delivery and fewer antibiotic related adverse events, but there are only limited data to support this. We aimed to investigate the safety and efficacy of a single 1 g dose of IV ceftriaxone in preventing infectious complications following EUS-FNA of PCL. METHODS: A retrospective analysis was conducted of EUS-FNA of PCL procedures performed at our center. We reviewed patient medical records for any presentation to a hospital in our district within 30 days of the procedure. An infectious complication was defined as fever/rigors, or bacteremia, or abdominal pain accompanied by imaging or laboratory results suggestive of infection, within 30 days of the procedure. Data collection included patient demographics, procedural data and outcome. RESULTS: EUS-FNA of 204 PCL (mean size 18.0 mm) was performed. Successful fluid aspiration was achieved in 94% of cases. Single-dose IV ceftriaxone was given in 146/204 (72%) cases. Four patients had a complication (pancreatitis n=1, post-procedural pain n=3). No infectious complications and no IV antibiotic-related adverse events were identified. CONCLUSION: A single dose of IV ceftriaxone appears to be a safe, effective and convenient intervention for preventing infectious complications after FNA.

Intraduodenal levodopa-carbidopa intestinal gel infusion improves both motor performance and quality of life in advanced Parkinson's disease.

We report the efficacy and adverse effect profile of intraduodenal levodopa-carbidopa intestinal gel (LCIG) infusion from patients treated in a single Australian movement disorder centre. We conducted an open-label, 12 month prospective study of treatment with LCIG in patients with advanced Parkinson's disease in a single tertiary referral hospital unit specialising in movement disorders. Patients with levodopa-responsive, advanced Parkinson's disease with motor fluctuations despite optimal pharmacological treatment were enrolled and underwent a 16 hour daily infusion of LCIG for 12 months. Fifteen participants completed the trial. The mean (± standard deviation) improvement in Unified Parkinson's Disease Rating Scale part III was 37 ± 11%, mean daily "off" period reduced from 6.3 ± 2 to 1.9 ± 2 hours, total daily "on" time increased from 10.2 ± 3 to 13.7 ± 2 hours, "on" period without dyskinesia increased from 4.5 ± 3 to 7.5 ± 5 hours, and 39-item Parkinson's Disease Questionnaire Summary Index score improved by 32.5 ± 35%. The most common adverse event was reversible peripheral neuropathy secondary to vitamin B12 ± B6 deficiency (40%), local tube problems (40%), and impulse control disorder (ICD) (27%). No patient had stoma bleeding or peritonitis. All patients with ICD had a past psychiatric diagnosis of depression with or without anxiety and a higher daily levodopa intake at 6 and 12 months of LCIG infusion. Intraduodenal LCIG improves motor performance, quality of life and daily "on" period. Prior to and during duodenal LCIG infusion, clinicians should monitor for peripheral neuropathy and vitamin B12 and B6 deficiency, as supplementation can reverse peripheral neuropathy. This trial is registered at Clinicaltrials.gov as CT00335153.

Feasibility and Safety of Overtubes for PEG-Tube Placement in Patients with Head and Neck Cancer.

Background. Percutaneous endoscopic gastrostomy (PEG) placement using the "pull" technique is commonly utilized for providing nutritional support in head and neck cancer (HNC) patients, but it may be complicated by peristomal metastasis in up to 3% of patients. Overtube-assisted PEG placement might reduce this risk. However, this technique has not been systemically studied for this purpose to date. Methods. Retrospective analysis of consecutive patients with HNC who underwent overtube-assisted PEG placement at Westmead Hospital, Australia, between June 2011 and December 2013. Data were extracted from patients' endoscopy reports and case notes. We present our technique for PEG insertion and discuss the feasibility and safety of this method. Results. In all 53 patients studied, the PEG tubes were successfully placed using 25 cm long flexible overtubes, in 89% prophylactically (before commencing curative chemoradiotherapy), and in 11% reactively (for treatment of tumor related dysphagia or weight loss). During a median follow-up period of 16 months, 3 (5.7%) patients developed peristomal infection and 3 others developed self-limiting peristomal pain. There were no cases of overtube-related adverse events or overt cutaneous metastases observed. Conclusions. Overtube-assisted PEG placement in patients with HNC is a feasible, simple, and safe technique and might be effective for preventing cutaneous metastasis.

Management of pancreatic collections with a novel endoscopically placed fully covered self-expandable metal stent: a national experience (with videos).

BACKGROUND: Recent medical literature on novel lumen-apposing stents for the treatment of pancreatic fluid collections (PFCs) is limited by small numbers, solo operators, and single-center experience. OBJECTIVE: To evaluate a recently developed lumen-apposing, fully covered self-expandable metal stent (FCSEMS) in the management of PFCs. DESIGN: Retrospective case series. SETTING: Thirteen tertiary and private health care centers across Australia. PATIENTS: Forty-seven patients (median age 51 years) who underwent endoscopic management of PFCs. INTERVENTION: Insertion of FCSEMS after PFC puncture under EUS guidance. A subgroup of 9 patients underwent direct endoscopic necrosectomy. MAIN OUTCOME MEASUREMENTS: Technical and clinical success rate, adverse event rate. RESULTS: The technical success rate was 53 of 54 patients (98.1%), and the initial clinical success rate was 36 of 47 (76.6%), which was sustained for more than 6 months in 34 of 36 (94.4%). Early adverse events included 4 cases (7.4%) of stent migration during direct endoscopic necrosectomy, 4 cases (7.4%) of sepsis, 1 case (1.9%) of bleeding, and 1 case (1.9%) of stent migration into the fistula tract. Late adverse events were 6 (11.1%) spontaneous stent migrations, 3 (5.6%) recurrent stent occlusions, 3 (5.6%) tissue ingrowth/overgrowth, and 2 (3.7%) bleeding into PFC. The majority of stents inserted (48 of 54, 88.9%) and removed (31 of 35, 88.6%) in our study were described by the operator as superior to pigtail stents with regard to ease of use. LIMITATIONS: Retrospective study. CONCLUSION: Although FCSEMSs are technically easier to insert and remove compared with traditional pigtail stents, there are significant limitations to the widespread use of FCSEMSs in the management of PFCs. These include cost, adverse events, and lower-than-expected resolution rates.

Endosonography-guided drainage of malignant fluid collections using lumen-apposing, fully covered self-expanding metal stents.

Endosonography (EUS)-guided drainage of paragastric fluid collections using fully covered self-expanding metal stents (FCSEMS) is now a well-established procedure. Recently, new and specially designed lumen-apposing, fully-covered metal cystgastrostomy stents have been employed for this indication. In this case series, the use of these new stents for the drainage of malignant fluid collections in three symptomatic patients is described. Cases included a large pancreatic pseudocyst, secondary to underlying acute lymphoblastic leukemia, and two large collections of loculated ascites due to metastatic ovarian and cervical cancer, respectively. Technical success in inserting the new stents was achieved in all three patients, and resulted in symptomatic relief. There were no clinically significant complications directly attributed to the stents. These new lumen-apposing cystgastrostomy stents may provide a viable, minimally invasive, and effective alternative for drainage of malignant fluid collections, either for definitive treatment or for palliation of symptoms.

Endoscopic necrosectomy of pancreatic necrosis: a systematic review.

AIM: To review the current status of the novel technique of endoscopic necrosectomy in the management of pancreatic necrosis after acute pancreatitis. METHODS: Studies were identified by searching Medline, PubMed and Embase databases for articles from January 1990 to December 2009 using the keywords "acute pancreatitis", "pancreatic necrosis" and "endoscopy". Additional papers were identified by a manual search of the references from the key articles. Case series of fewer than five patients and case reports were excluded. RESULTS: Indications, techniques and outcomes of endoscopic necrosectomy were analysed. There were no randomised controlled trials identified. Ten case series were included in this analysis. There were a total of more than 1,100 endoscopic necrosectomy procedures in 260 patients with pancreatic necrosis. One hundred fifty-five were proven to be infected necrosis on culture. The overall mortality rate was 5%. The mean procedure-related morbidity rate was 27%. The rate of complete resolution of pancreatic necrosis with the endoscopic method alone was 76%. CONCLUSIONS: Endoscopic necrosectomy is a safe and effective treatment option in selected patients with pancreatic necrosis after acute pancreatitis. Future studies will be required to further define the selection criteria and the techniques for the endoscopic procedure.

Severity of initial stent angulation predicts reintervention after successful palliative enteral stenting for malignant luminal obstruction.

BACKGROUND AND AIM: Recurrent stent obstruction necessitating reintervention is problematic and incompletely understood. The aim of the present study was to identify factor(s) predisposing to reintervention. METHODS: Retrospective review of patients (n = 117) referred to a single major endoscopic referral centre for palliative enteral stenting from 1999 to 2006. Twelve were excluded due to inadequate follow-up data (n = 7) or initial radiographic documentation (n = 5). A total of 105 patients (gastroduodenal n = 57, colonic n = 48) were therefore analyzed. The primary outcome of interest was recurrent obstruction necessitating reintervention. Kaplan-Meier analysis of potential factors predisposing to reintervention, including stent angulation (mild [<15°], moderate [15°-90°], severe [>90°]) was completed for 98 patients (technically successful enteral stenting). RESULTS: Technical and clinical success were achieved in 98 of 105 (93.3%) and 92 of 98 (93.9%) cases, respectively. Post-stenting median survival was 97.5 days (range 3-1054). Eighteen patients (18.4%) required reintervention for stent obstruction at a median time to reintervention of 85 days (range 7-481). Increased stent angulation (severe vs mild hazard ratio 6.73 (95% confidence interval 1.59-27.59), P = 0.009) was the only statistically significant factor in multivariate analysis predicting reintervention. CONCLUSIONS: Despite its limitation as a retrospective review, this study found that reintervention for stent obstruction is necessary in almost one in five cases, and increasing severity of stent angulation is the most important risk factor.

Succinylated gelatin substantially increases en bloc resection size in colonic EMR: a randomized, blinded trial in a porcine model.

BACKGROUND: Succinylated gelatin (SG) is an inexpensive colloid that may combine ease of use with the advantages of a colloid to potentially increase EMR specimen size, leading to a higher rate of en bloc resection. OBJECTIVE: To evaluate the safety, efficacy, and impact on EMR specimen size of SG as a submucosal (s.m.) injectant in comparison with normal saline solution (NS). DESIGN: Randomized, blinded, controlled trial conducted with Animal Ethics Committee approval. SETTING: Academic hospital. SUBJECTS: Ten swine. INTERVENTIONS: Sixty EMRs (30 using SG vs 30 using NS as 3 paired experiments per animal) of the largest possible en bloc snare resection of normal colonic mucosa after s.m. injection of a fixed volume of either SG or NS. MAIN OUTCOME MEASUREMENTS: EMR specimen size, duration of s.m. cushion, duration of procedure, ratio of vertical elevation to lateral spread of injectant, ease of resection, adverse effects, perforation, histopathology of EMR sites in colectomy specimens at necropsy (for inflammatory cell content, depth of ulceration, and vascular or ischemic changes). RESULTS: The mean subject weight was 53 kg. The mean EMR specimen dimensions and surface area were significantly larger with SG (length 37 vs 31 mm, P = .031; width 32 vs 26 mm, P = .022; surface area 9.5 cm(2) vs 6.7 cm(2), P = .044, respectively). The median s.m. cushion duration was 60 minutes with SG versus 15 minutes with NS (P = .005). The median procedure duration with SG was 2.6 minutes vs 2.5 minutes with NS (P = .515). The ratio of vertical elevation to lateral spread of injectant (mean score on a 3-point scale) was 3 with SG versus 2 with NS (P = .228). Ease of resection score (mean score on a 10-point scale) was 8 with SG versus 7 with NS (P = .216). There were no systemic adverse effects, hypersensitivity reactions, or bleeding episodes. There were 2 perforations (treated with clips) with SG and 1 with NS (P = 1.0). Blinded histopathologist assessment of necropsy colectomy specimens did not identify any significant differences between SG and NS EMR sites. LIMITATIONS: Animal study. CONCLUSIONS: SG is safe and results in a 42% increased surface area for en bloc EMR. Given its other favorable properties, it represents a significant step toward defining the ideal EMR solution.

Endoscopic resection for Barrett's high-grade dysplasia and early esophageal adenocarcinoma: an essential staging procedure with long-term therapeutic benefit.

OBJECTIVES: Patients with Barrett's high-grade dysplasia (HGD) or early esophageal adenocarcinoma (EAC) that is shown on biopsy alone continue to undergo esophagectomy without more definitive histological staging. Endoscopic resection (ER) may provide more accurate histological grading and local tumor (T) staging, definitive therapy, and complete Barrett's excision (CBE); however, long-term outcome data are limited. Our objective was to demonstrate the effect on histological grade or local T stage, efficacy, safety and long-term outcome of ER for Barrett's HGD/EAC and of CBE in suitable patients. METHODS: This prospective study at two Australian academic hospitals involved 75 consecutive patients over 7 years undergoing ER for biopsy-proven HGD or EAC, using multiband mucosectomy or cap technique. In addition, CBE by 2-3-stage radical mucosectomy was attempted for all Barrett's segments

Minor papilla sphincterotomy for pancreatitis due to pancreas divisum.

BACKGROUND: Pancreas divisum (PD) is the commonest congenital pancreatic abnormality and is implicated as a cause of acute recurrent pancreatitis (ARP). We report our experience in minor papilla sphincterotomy (MPS) for this condition. Studies published at present have not examined MPS as the primary treatment method in a homogenous (i.e. only those with ARP) patient group. METHODS: Patients with PD and ARP were identified from an endoscopic database. Treatment protocol consisted of minor papilla guidewire cannulation and sphincterotomy with either sphincterotome over the wire or needle knife over pancreatic stent. A 5-Fr stent was placed for 1 week. Adjunctive therapy was carried out as required. Follow-up data was collected by interview with the patient and referring doctors and review of the medical record. RESULTS: Twenty-one patients underwent MPS for PD and ARP (median age = 33 years, range 9-77 years, men = 14). Median number of procedures to achieve cannulation and MPS was 1 (range 1-3). Complications encountered were pancreatitis (n = 2) and pain (n = 3). MPS restenosis occurred in 2. Adjuvant therapy was required in 14: stricture dilatation (n = 9), stone extraction (n = 7) and extracorporeal shock-wave lithotripsy (n = 6). Complete stone clearance was achieved in 7/7. Median follow up was 38 months (range 4-67 months). Median total number of pancreatitis episodes and hospitalizations pre-MPS were 4 and 2, respectively (range 1-20 and 0-5, respectively). Post-MPS these were reduced to 0 and 0, respectively (range 0-8 and 0-4; P = 0.0007 and P = 0.0003), with complete abolition of episodes in 13 patients. CONCLUSION: MPS in association with other endoscopic therapies imparts a significant clinical benefit to patients with ARP and PD. Complete clinical resolution occurs in the majority. Treatment is safe, and the response is durable.

A case series of symptomatic intraluminal duodenal duplication cysts: presentation, endoscopic therapy, and long-term outcome (with video).

BACKGROUND: Duodenal duplication cysts are rare congenital anomalies. Symptomatic cases have classically been treated by surgical resection, which can be complex because of the close proximity of the cysts to the papilla. OBJECTIVE: To describe a series of 8 patients with symptomatic duodenal duplication cysts who were treated endoscopically, with a special focus on the long-term outcome. DESIGN: Retrospective case series. SETTING: Three tertiary-care European academic hospitals. PATIENTS: Eight patients, age 8 to 72 years, were treated endoscopically for symptomatic intraluminal duodenal duplication cysts between 1981 and 2006. Seven patients presented with acute pancreatitis, and one patient presented with jaundice. INTERVENTION: Endoscopic incision and marsupialization of the cysts was performed by using a variety of endoscopic tools (needle-knife and regular sphincterotomes, cystotomes, and polypectomy snares). MAIN OUTCOME MEASUREMENTS: Technical success of endoscopic intervention and long-term clinical recurrence of symptoms. RESULTS: No major complications occurred. All patients remained asymptomatic at a median follow-up of 7.3 years. LIMITATIONS: Retrospective study; the small number of patients. CONCLUSIONS: The endoscopic treatment of symptomatic intraluminal duodenal duplication cysts is a safe and effective technique, with excellent long-term results. It represents a minimally invasive alternative to surgical resection and might be considered the preferred therapeutic modality for these cases.

EUS-guided cholecystenterostomy: a new technique (with videos).

BACKGROUND: The cornerstone of management for acute cholecystitis is cholecystectomy. However, surgical intervention is contraindicated in the occasional patient. EUS-guided transduodenal gallbladder drainage may represent an effective minimally invasive alternative. OBJECTIVES: To describe a new technique, EUS-guided cholecystenterostomy. DESIGN AND SETTING: A single-center retrospective case series. PATIENTS: Three patients with severe acute cholecystitis unresponsive to conservative management who were deemed unfit for cholecystectomy. INTERVENTIONS: Under combined EUS and fluoroscopic guidance, cholecystenterostomy was performed via needle puncture, guidewire insertion, cystoenterostome passage, and stent placement. MAIN OUTCOME MEASURES: Technical success, clinical progress, immediate and long-term complications, and recurrence of cholecystitis. LIMITATIONS: Pilot series. RESULTS: Cholecystenterostomy was performed successfully in all patients. Rapid improvement in clinical status and inflammatory parameters ensued. A minor intraprocedural bile leak occurred in 1 patient, without significant clinical sequelae. Cholecystitis did not recur in any patient. CONCLUSIONS: EUS-guided cholecystenteric drainage is technically feasible and appears to be a safe and effective procedure. Via this technique, gallbladder drainage and resolution of related sepsis may be achieved in patients with acute cholecystitis who are unfit for surgery.
