RESUMO
BACKGROUND AND AIMS: High rates of technical and clinical success were reported for lumen-apposing metal stent (LAMS) placement for peripancreatic fluid collection (PFC) drainage. However, data on the adverse event (AE) rates are heterogeneous. The aim of this study was to evaluate the incidence, severity, management, and risk factors of AEs related to the use of LAMSs for drainage of PFCs in a large cohort of patients. METHODS: This is a multicenter, international, retrospective review from 15 centers of all patients who underwent placement of LAMSs for the management of PFCs. A nested case-control study was conducted in patients with (case) or without (control) AEs. RESULTS: Three hundred thirty-three procedures in 328 patients were performed (5 patients treated with 2 LAMSs). Technical success was achieved in 321 patients (97.9%). Three hundred four patients were finally included in the study (7 excluded for lost to follow-up information; 10 excluded for deaths unrelated to LAMSs). The rate of clinical success was 89.5%. Seventy-nine LAMS-related AEs occurred in 74 of 304 patients (24.3%), after a mean time of 25.3 days (median, 18 days; interquartile range, 6-30) classified as 20 (25.3%) mild, 54 (68.4%) moderate, or 5 (6.3%) severe. On multivariable analysis compared with control subjects, cases were more likely to have walled-off necrosis (WON) versus pancreatic pseudocysts (odds ratio, 2.18; 95% confidence interval, 1.09-4.46; P = .028), whereas cases were less likely to have undergone tract (balloon) dilation (yes vs no; odds ratio, .47; 95% confidence interval, .22-.93; P = .034). CONCLUSIONS: Data from this large international retrospective study confirm that the use of LAMSs for management of PFCs has excellent technical and good clinical success rates. The rate of AEs, however, is not negligible and should be carefully considered before using these stents for drainage of PFCs and in particular for WON. Further prospective studies are needed to confirm these findings. (Clinical trial registration number: NCT03544008.).

BACKGROUND: We report our experience of treating anastomotic strictures using a novel type of fully covered metal stent (FCSEMS). This stent, known as the Kaffes Stent, is short-length with an antimigration waist and is easily removable due to long retrieval wires deployed within the duodenum. METHODS: Sixty-two patients underwent ERCP and Kaffes stent insertion for post-transplant anastomotic strictures following confirmation of a stricture on MRCP. These patients were retrospectively analysed for immediate and long-term stricture resolution, improvement in symptoms and liver function tests (LFTs), stricture recurrence and complication rates. RESULTS: Of the 56 patients who had their stent removed at the time of analysis, 54 (96%) had immediate stricture resolution and 42 continued to have long-term resolution (mean follow-up period was 548 days). Of the 16 patients with symptoms of biliary obstruction, 13 had resolution of their symptoms. Overall, there was a significant improvement in LFTs after stent removal compared to before stent insertion. Complication rates were 15% with only one patient requiring biliary reconstruction. CONCLUSIONS: The Kaffes stent is effective and safe at resolving post liver transplant biliary anastomotic strictures.

BACKGROUND/AIMS: There are few studies assessed the efficacy and mortality of endoscopic retrograde cholangiopancreatography (ERCP) for the removal of common bile duct (CBD) stones in the elderly aged ≥90 years. We aimed to assess the safety and efficacy of endoscopic removal of CBD stones in nonagenarians. METHODS: We retrospectively reviewed ERCP reports for CBD stone removal. The endoscopic and therapeutic outcomes were collected. The length of stay (LOS), the total number of adverse events, and mortality rate were compared between groups. RESULTS: A total of 125 nonagenarians were compared with 1,370 controls (65-89 years old individuals). The mean LOS for nonagenarians was significantly higher than in controls (13.6 days vs. 6.5 days). Completed intended treatment was similar in the nonagenarians and controls (89.8% and 89.5%, respectively). The overall complication rate did not differ between the groups. However, nonagenarians had a higher incidence of post-ERCP pneumonia (3.9%). None of the nonagenarians were readmitted to the hospital within 7 days. Four nonagenarians (3.2%) and 25 (1.8%) controls died within 30 days. CONCLUSION: Advanced age alone did not affect the decision to perform the procedure. However, prompt diagnosis and treatment of post-ERCP pneumonia in nonagenarians could improve the outcomes and reduce mortality.
RESUMO
Objective: Faecal calprotectin (fCAL) is an established marker of intestinal inflammation in inflammatory bowel disease (IBD). Disproportionally high fCAL levels, for the severity of intestinal inflammation, have been previously observed in primary sclerosing cholangitis associated IBD (PSC-IBD). The aim of this study was to test the hypothesis that fCAL is a marker of biliary injury in PSC-IBD. Methods: We used two cohorts: (1) post hoc analysis of a colonoscopic surveillance study allowing correlation of fCAL to endoscopic severity as measured by the ulcerative colitis endoscopic index of severity (UCEIS) in PSC-IBD (n=20) and ulcerative colitis (UC, n=20) and (2) prospective recruitment of patients attending for endoscopic retrograde cholangiopancreatography allowed the correlation of fCAL to biliary calprotectin (n=8). Results: A strong correlation was seen between fCAL and UCEIS in UC (r=0.821, 95% CI (0.585 to 0.929), p<0.0001). In PSC-IBD, the correlation was weaker (r=0.596, 95% CI (0.195 to 0.8260), p=0.006). PSC-IBD patients with endoscopically quiescent colitis (UCEIS: 0-1) had higher fCAL than patients with UC (279 µg/g, IQR (68-601) vs 30 µg/g, IQR (14-107), p=0.015). This was associated with higher risk of biliary complications like need for antibiotics or instrumentation (HR 16.39, 95% CI (2.98 to 90.25)) rather than colitis flares (follow-up: 12 months). Calprotectin measured in faeces correlated positively with biliary calprotectin (r=0.898, p=0.0024). Conclusion: fCAL is a surrogate marker for biliary inflammation in PSC-IBD. Trial registration number: NCT02543021.
RESUMO
BACKGROUND AND AIMS: Portal cavernoma associated cholangiopathy (PCC) is an uncommon disease in western countries. We describe our experience in seven patients with PCC, in particular the endoscopic management. We describe the mode of presentation, frequent symptoms and the outcome of different treatment modalities of patients with symptomatic PCC. METHODS: Prospectively maintained database was reviewed at a large tertiary referral unit in London, UK. Data included therapeutic interventions, outcomes and complications. RESULTS: Seven patients with PCC were followed for a median of 87 months [interquartile range (IQR), 62-107.5]. Causes of EHPVO included (hypercoagulable status, n=2, peritoneal tuberculosis n=1, neonatal sepsis, n=1, idiopathic, n=3). Acute cholangitis constituted the most recurring complications in all patients during the disease course. Endoscopic intervention was deemed required in all patients for biliary decompression, with 5 out 7 patients managed with repeat endoscopic sessions, (total=23 ERCPs). Surgical portal decompression (meso-caval shunt) was successfully performed in one patient and another patient underwent liver transplantation for decompensated liver cirrhosis. When endoscopic intervention was indicated, a fully covered self expanding metal stent (FcSEMS) provided a longer "symptoms free" period when compared to plastic stent, 7.5 (IQR, 4.75-18.25) and 4 (IQR, 3.5-7) months respectively, P=0.03. Bile duct bleeding occurred in two patients during ERCP procedure, however none of the patients had spontaneous haemobilia. Both patients were successfully treated by FcSEMS. CONCLUSION: Acute cholangitis is a common presentation and recurrent complication during the disease course. Spontaneous haemobilia seems to be uncommon, however it is a significant potential hazard during endoscopic intervention. Insertion of FcSEMS may remodel choledochal varices and provide a longer "symptoms free" period compared to plastic stents.

OBJECTIVE: General anaesthesia (GA) has been increasingly used for advanced endoscopic procedures in particular endoscopic retrograde cholangiopancreatography (ERCP). Given the increasing pressure on many hospitals, the delivery of such service on a regular basis may not always be possible. We established a new day case 'GA ERCP' service. We describe our experience in evaluating the safety and overall feasibility of this new service. DESIGN: Prospective database has been interrogated for the period from March 2015 to December 2016. We documented patients' demographics, ERCP indications, American Society of Anesthesiologists (ASA) status, Cotton grade and complications. RESULTS: 67 patients were referred to endoscopy unit at King's College Hospital (KCH), for urgent day case GA ERCP from nine referring hospitals. The main indications were failed ERCP under sedation 47.8% (32/67), and unavailability of ERCP locally 41.8% (28/67). A total of 64 patients were actually transferred to KCH; 57.8% (37/64) women with a median age 55.8 years (range 23-90). 78.1% (50/64) of patients had a virgin papilla, with 39% (25/64) were ASA ≥3. The Cotton grade was ≥ 3 in 50% (32/64) patients. ERCP was completed successfully in 87.5% (56/64). For patients with previous failed ERCP, repeat ERCP under GA was successful in 75% (24/32). All patients were safely discharged back to their referring hospitals after the short observation period post-ERCP. CONCLUSIONS: Urgent inpatient transfers between hospitals for performing ERCP under GA as a day case is safe and feasible. The new GA ERCP pathway can be replicated by other UK centres.
