RESUMEN

BACKGROUND/OBJECTIVES: The epidemiology, natural history, complications, and therapeutic management of chronic pancreatitis (CP) are not well described at the national level. This multi-centre prospective observational study involving eight Belgian hospitals aimed to improve the understanding of these aspects of CP in Belgium. METHODS: All patients with a diagnosis of CP based on imaging were eligible for this study. Data were gathered regarding epidemiology, etiology, CP complications, and treatment modalities. RESULTS: A total of 809 patients were included between 1/9/2014 and 31/8/2015. Most patients (794) were adults ≥16-years old, 74% were male, the median age at symptom onset was 47 (38-57) years, the median disease duration was 7 (3-13) years, and the median Izbicki pain score (IPS) was 96 (0-195). The main etiological risk factors according to the TIGAR-O classification were alcohol and tobacco (67%). Current drinkers had lower body mass index (BMI) (21.4 kg/m2 vs 24.1 kg/m2), higher IPS (110 vs 56), and longer inability to work than non-drinkers. Current smokers had lower BMI (21.5 kg/m2 vs 25 kg/m2) and higher IPS (120 vs 30) than non-smokers. Endocrine insufficiency and/or clinical steatorrhea was recorded in 41% and 36% of patients, respectively. The highest IPS was reported in patients with ongoing endotherapy (166 vs 50 for patients who completed endoscopy). CONCLUSION: This multicentric study on CP patients showed that current alcohol drinking and smoking are associated with pain and malnutrition. Pain scores were higher in patients with ongoing endotherapy, independently of surgery.

RESUMEN

Serum levels and liver expression of CCL2 are increased in patients with alcoholic hepatitis (AH). In an experimental model of alcoholic liver disease (ALD), CCL2 was implicated in proinflammatory cytokines activation and hepatic lipid metabolism, but its role in human disease is currently unknown. In a large cohort of ALD patients, we analysed plasma levels and liver expression of CCL2 and their association with liver disease severity and histological lesions. We also studied the relationship between -2518 A > G CCL2 and CCR2 190 A/G polymorphisms and severity of ALD. We show that CCL2 plasma levels are increased in ALD patients compared with healthy subjects. AH patients had significantly higher plasma levels and hepatic expression of CCL2 than patients without AH. Plasma levels and hepatic expression of CCL2 were associated with disease severity. CCL2 liver expression was correlated with neutrophil infiltrate and interleukin (IL)-8 expression, but not with steatosis. Moreover, there were more G-allele carriers of -2518 A > G CCL2 polymorphism in severe AH patients than in other ALD patients. Our results demonstrate that CCL2 is increased in ALD, particularly in severe forms, and suggest a role for CCL2 in the pathogenesis of ALD via neutrophil recruitment.

RESUMEN

Suboptimal bowel cleansing prior to colonoscopy impairs the efficacy and safety of the procedure. A new system for intracolonic cleansing has been developed, which includes a disposable catheter device that is inserted through the working channel of a standard colonoscope and an irrigation unit with predefined pressure and flow rate. The aim of the current study was to assess the safety and efficacy of this novel system for the improvement of bowel cleansing during colonoscopy. A total of 42 patients with suboptimal bowel preparation were systematically allocated, in a 1:1 ratio, to either the study group (JetPrep system, n = 21) or the control group (syringe irrigation, n = 21). The cleansing efficacy was evaluated using a segmental scoring scale to rate the bowel preparation level before and after irrigation. One patient from the study group was excluded from the efficacy analysis due to treatment with both techniques. The JetPrep system was significantly superior to syringe irrigation (P = 0.0001). No adverse events were reported. This study suggests that the safety profile of the JetPrep system is comparable to standard irrigation and shows that the device significantly improves suboptimal bowel preparation.

RESUMEN

This article is part of a combined publication that expresses the current view of the European Society of Gastrointestinal Endoscopy about endoscopic biliary stenting. The present Clinical Guideline describes short-term and long-term results of biliary stenting depending on indications and stent models; it makes recommendations on when, how, and with which stent to perform biliary drainage in most common clinical settings, including in patients with a potentially resectable malignant biliary obstruction and in those who require palliative drainage of common bile duct or hilar strictures. Treatment of benign conditions (strictures related to chronic pancreatitis, liver transplantation, or cholecystectomy, and leaks and failed biliary stone extraction) and management of complications (including stent revision) are also discussed. A two-page executive summary of evidence statements and recommendations is provided. A separate Technology Review describes the models of biliary stents available and the stenting techniques, including advanced techniques such as insertion of multiple plastic stents, drainage of hilar strictures, retrieval of migrated stents and combined stenting in malignant biliary and duodenal obstructions.The target readership for the Clinical Guideline mostly includes digestive endoscopists, gastroenterologists, oncologists, radiologists, internists, and surgeons while the Technology Review should be most useful to endoscopists who perform biliary drainage.

RESUMEN

The aim of the present study was to describe success rates, complications, and outcome in patients who underwent percutaneous endoscopic jejunostomy (PEJ) because of gastroparesis due to previous lung transplantation. Between October 2008 and May 2011, 14 attempts at PEJ placement were made in 12 patients in our center. Of the 14 attempts, 11 were successful, giving a technical success rate of 78.6 %. Median duration of followup was8.5 months (2­15 months). No immediate complications were reported. Two severe complications occurred during follow up (one volvulus and one jejunocolic fistula). Jejunal nutrition was well tolerated in most of patients (9 /10). PEJ insertion is a feasible technique, which could help to provide nutritional support for patients with gastroparesis and previous lung transplantation.

RESUMEN

BACKGROUND AND AIMS: Clarification of the position of the European Society of Gastrointestinal Endoscopy (ESGE) regarding the interventional options available for treating patients with chronic pancreatitis. METHODS: Systematic literature search to answer explicit key questions with levels of evidence serving to determine recommendation grades. The ESGE funded development of the Guideline. SUMMARY OF SELECTED RECOMMENDATIONS: For treating painful uncomplicated chronic pancreatitis, the ESGE recommends extracorporeal shockwave lithotripsy/endoscopic retrograde cholangiopancreatography as the first-line interventional option. The clinical response should be evaluated at 6 - 8 weeks; if it appears unsatisfactory, the patient's case should be discussed again in a multidisciplinary team. Surgical options should be considered, in particular in patients with a predicted poor outcome following endoscopic therapy (Recommendation grade B). For treating chronic pancreatitis associated with radiopaque stones ≥ 5 mm that obstruct the main pancreatic duct, the ESGE recommends extracorporeal shockwave lithotripsy as a first step, combined or not with endoscopic extraction of stone fragments depending on the expertise of the center (Recommendation grade B). For treating chronic pancreatitis associated with a dominant stricture of the main pancreatic duct, the ESGE recommends inserting a single 10-Fr plastic stent, with stent exchange planned within 1 year (Recommendation grade C). In patients with ductal strictures persisting after 12 months of single plastic stenting, the ESGE recommends that available options (e. g., endoscopic placement of multiple pancreatic stents, surgery) be discussed in a multidisciplinary team (Recommendation grade D).For treating uncomplicated chronic pancreatic pseudocysts that are within endoscopic reach, the ESGE recommends endoscopic drainage as a first-line therapy (Recommendation grade A).For treating chronic pancreatitis-related biliary strictures, the choice between endoscopic and surgical therapy should rely on local expertise, patient co-morbidities and expected patient compliance with repeat endoscopic procedures (Recommendation grade D). If endoscopy is elected, the ESGE recommends temporary placement of multiple, side-by-side, plastic biliary stents (Recommendation grade A).

RESUMEN

PillCam colon capsule endoscopy (CCE) is an innovative noninvasive, and painless ingestible capsule technique that allows exploration of the colon without the need for sedation and gas insufflation. Although it is already available in European and other countries, the clinical indications for CCE as well as the reporting and work-up of detected findings have not yet been standardized. The aim of this evidence-based and consensus-based guideline, commissioned by the European Society of Gastrointestinal Endoscopy (ESGE) is to furnish healthcare providers with a comprehensive framework for potential implementation of this technique in a clinical setting.

RESUMEN

Biliary stenting is widely used to palliate malignant obstruction or to treat benign biliary diseases. Recently, the most important changes have related to self-expandable metal stents (SEMSs), which are now available in a wide variety of designs, and to treatment techniques. This article is part of a combined publication that expresses the current view of the European Society of Gastrointestinal Endoscopy (ESGE) about endoscopic biliary stenting: a technology review describes the stent models and stenting techniques, and a separate clinical guideline states the evidence and recommendations regarding stenting.

RESUMEN

BACKGROUND AND STUDY AIMS: Covered self-expanding metal stents (SEMSs) have proven effective for managing malignant bile duct strictures and may reduce risk of tumor ingrowth. A new nitinol partially covered biliary SEMS was prospectively evaluated. PATIENTS AND METHODS: 70 patients with inoperable extrahepatic biliary obstructions were enrolled in a prospective multicenter trial, and followed up to 6 months or death, whichever came first. Primary endpoint was adequate palliation defined as absence of recurrent biliary obstruction from partly covered SEMS placement to end of follow-up. RESULTS: Mean age of the patients was 69 years and 52 % were men. Pancreatic carcinoma was present in 68 %. One stent was placed in 67 patients, two patients received two, and in one patient a guide wire could not traverse the stricture. In 55 % of patients the SEMS was inserted de novo and in 45 % for exchange with a plastic stent. Technical success was 97 %. At 6 months, 62 % of patients were free of obstructive symptoms; compared with baseline the mean number of symptoms per patient was significantly reduced (3.1 at baseline, 0.6 at 6 months; P < 0.0001) and total bilirubin levels dropped by 73 %. There were four cases of recurrent biliary obstruction, due to stent migration (2), tumor overgrowth (1), and sludge formation (1). Device-related complications included cholecystitis (3), right upper quadrant pain (1), and moderate pancreatitis (1). No tumor ingrowth was reported. CONCLUSIONS: This new partially covered nitinol SEMS is easily inserted, and safe and effective in the palliation of biliary obstruction secondary to malignant bile duct strictures.

RESUMEN

BACKGROUND AND AIMS: Endoscopic ultrasound fine-needle aspiration/biopsy (EUS-FNA/FNB) is highly accurate, but discrepancies between cytological and surgical diagnoses are still observed. We aimed to determine its accuracy and monitor quality indicators in our facilities. PATIENTS AND METHODS: We performed a retrospective review of all cases of pancreatic solid lesions evaluated by EUS-FNA/FNB, between July 2015 and June 2018, in two centers. Cytological and surgical findings were categorized into five groups: benign, malignant, suspect of malignancy, undetermined and insufficient for diagnosis. Final diagnosis was based on surgical diagnosis and, in patients who did not undergo surgery, on clinical outcome after 6 months follow-up. RESULTS: Altogether, 142 patients were included. FNA was the preferred tissue acquisition method (88%), with a predilection for the FNA 22G needle (57%). Cytology was insufficient for diagnosis in 2 cases, therefore a full diagnostic sample was available in 98.6% of the patients (>90%, ESGE target). Fifty-five (38.7%) patients underwent surgery. In term of cancer diagnosis, comparison with final surgical pathology (n=55) revealed 89% true positives, 5.5% true negatives, 3.6% false positives and 1.8% false negatives. When combining surgical diagnosis and clinical outcomes together, EUS-guided sampling sensitivity was 97.4% (92.5-99.5), specificity was 92.3% (74.9-99.1), positive predictive value was 98.2% (93.6- 99.5), negative predictive value was 88.9% (72.3-96.1) and accuracy was 96.4% (91.9-98.8). Post-procedural acute pancreatitis was reported in 2 patients (1.4%). CONCLUSIONS: These results reveal a performance for diagnostic tissue sampling well above the ESGE proposed target standard. Also, the uncommon high specificity illustrates the determining role of the pathologist's final interpretation and diagnosis.

RESUMEN

Pancreatitis is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP). Risk factors for post-ERCP pancreatitis (PEP) are both patient-related and procedure-related. Identification of patients at high risk for PEP is important in order to target prophylactic measures. Prevention of PEP includes administration of nonsteroidal inflammatory drugs (NSAIDs), use of specific cannulation techniques, and placement of temporary pancreatic stents. The aim of this guideline commissioned by the European Society of Gastrointestinal Endoscopy (ESGE) is to provide practical, graded, recommendations for the prevention of PEP.

RESUMEN

Chemokines and their receptors are involved in tumourigenicity and clinicopathological significance of chemokines receptor expression in pancreatic adenocarcinoma (PA) is not fully understood. This study was conducted to determine patients' outcome according to the expressions of CXCR4, CXCR7 and HIF-1alpha after resection of PA. Immunohistochemistry for CXCR4, CXCR7 and HIF-1alpha expressions as well as cell proliferative index (Ki-67) was conducted in 71 resected (R0) PA and their 48 related lymph nodes (LN) using tissue microarray. CXCR4 and CXCR7 expressions were positively correlated to HIF-1alpha suggesting a potential role of HIF-1alpha in CXCR4 and CXCR7 transcription activation. Patients with CXCR4(high) tumour expression had shorter OS than those with low expression (median survival: 9.7 vs 43.2 months, P=0.0006), a higher risk of LN metastases and liver recurrence. In multivariate analysis, high CXCR4 expression, LN metastases and poorly differentiated tumour are independent negative prognosis factors. In a combining analysis, patients with a CXCR7(high)/CXCR4(high) [corrected] tumour had a significantly shorter DFS and OS than patients with a CXCR4(low)/CXCR7(low) [corrected] tumour. CXCR4 in resected PA may represent a valuable prognostic factor as well as an attractive target for therapeutic purpose.

RESUMEN

In chronic liver disease, high circulating interleukin (IL)-6 contrasts with a poor acute phase response. We evaluated the impact of liver and circulating IL-6-receptor (IL-6R) forms on IL-6 bioactivity in chronic liver disease. IL-6, soluble IL-6-receptor and sgp130 levels were assayed in plasma from 45 patients with alcoholic liver disease, 84 with hepatitis C virus (HCV) infection undergoing transjugular liver biopsies and 15 healthy subjects. IL-6R mRNA was quantified on liver extracts from 54 patients with alcoholic liver disease with or without cirrhosis and 18 HCV-infected patients. The effect of gp130-Fc on fibrinogen secretion induced by IL-6 trans-signalling was evaluated on hepatocyte cultures. Levels of plasma IL-6 and sgp130, but not soluble IL-6R, increased with the stage of chronic liver disease, and correlated significantly with disease severity. Alcoholic liver disease patients had higher plasma IL-6 levels than hepatitis C, but lower liver IL-6R expression. In alcoholic and HCV-related liver diseases, liver IL-6R expression decreased with advanced fibrosis stage. In vitro, on hepatocytes, gp130-Fc blunted the acute phase response while soluble IL-6R enhanced IL-6 stimulation. In advanced chronic liver disease, high plasma IL-6 is associated with low liver IL-6R expression. This situation enables high plasma sgp130 to act as a major negative regulator of liver IL-6 trans-signalling, as demonstrated functionally here on hepatocytes. This might explain the poor acute phase response induced by IL-6 in chronic liver disease.

RESUMEN

Anastomotic leaks frequently occur after bariatric surgery and their management includes different options. The present study describes the management of enterocutaneous fistulas in patients in whom surgical or endoscopic treatments have failed, by insertion of a biomaterial (Surgisis fistula plug) to facilitate healing of the gastrocutaneous fistula. Five patients with leaks after bariatric surgery were treated. All patients had undergone previous failed surgical or endoscopic attempt(s) at closure. Our technique entailed insertion of the Surgisis fistula plug into the fistula tract by a "rendezvous" procedure, via both percutaneous and endoscopic routes. The data were collected retrospectively. Initially, two patients were treated by fistula plug alone and three received fistula plug plus a self-expanding stent. In two patients, cutaneous fistula outflow ceased within a few days. The other three patients required one additional endoscopic procedure. At the end we observed healed leaks in four of the five patients (80 %). The median follow-up duration was 18 months. In conclusion, the combined therapy consisting of fistula plug implantation with optional stenting helps closure in these difficult refractory cases of gastrocutaneous fistula.

RESUMEN

BACKGROUND AND STUDY AIMS: Optical coherence tomography (OCT) uses infrared light reflectance to produce high-resolution cross-sectional tissue images. The aim of this study was to demonstrate the feasibility of biliary intraductal OCT during endoscopic retrograde cholangiopancreatography (ERCP) and to assess the potential of the method to detect malignant biliary strictures. PATIENTS AND METHODS: Thirty-seven patients with biliary strictures were studied during therapeutic ERCP. Malignant strictures were defined as those that demonstrated malignant cells in brushing and/or biopsy specimens, and/or endoscopic ultrasound-guided fine-needle aspiration and/or surgery. Strictures that did not have malignant cells in resected specimens and were without clinical/radiological evidence of disease progression for at least a 12-month follow-up period were considered as benign. Two OCT criteria for malignancy were considered: unrecognizable layer architecture; and presence of large, nonreflective areas compatible with tumor vessels. Sensitivity and specificity for brushings/biopsies as well as OCT criteria were calculated. RESULTS: Nineteen patients had malignant and 16 had benign strictures. In two patients, OCT assessment could not be performed due to tight strictures. Malignancy was confirmed by biliary brushings/biopsies in 12/19 (63 %) patients. OCT revealed that two malignancy criteria were encountered in 10/19 (53 %) and at least one criterion in 15/19 (79 %) patients with malignant strictures. No patient with benign stricture met both criteria and 5/16 met one criterion (31 %). Combining brushings/biopsy with the observation of at least one OCT criterion resulted in the diagnosis of malignancy in 16/19 (84 %) patients. CONCLUSIONS: OCT may improve the sensitivity and diagnostic accuracy of biliary brushings/biopsies alone.

RESUMEN

BACKGROUND AND STUDY AIMS: To determine long-term outcome after treatment with an intragastric balloon for 6 months, with no structured weight maintenance program offered after balloon removal. PATIENTS AND METHODS: 100 consecutive overweight/obese individuals (mean body mass index [BMI] 35.0 +/- 5.6 kg/m (2)) were prospectively followed after endoscopic implantation of a saline-filled intragastric balloon; 97 completed final follow-up at a mean of 4.8 +/- 1.6 years. Successful intragastric balloon therapy was defined as weight loss at 6 months of > or = 10 % of weight at baseline, that remained > or = 10 % until 2.5 years, without bariatric surgery. All analyses followed intention-to-treat principles. RESULTS: At 6 months, mean weight loss was 12.6 +/- 8.3 kg, 63 individuals had > or = 10 % baseline weight loss; no severe morbidity was detected. During the first and second years following intragastric balloon removal, mean body mass increased by 4.2 +/- 6.8 and 2.3 +/- 6.0 kg, respectively ( P < 0.001 for both year-on-year comparisons). At 2.5 years, intragastric balloon therapy had been successful in 24 participants. At final follow-up (4.8 +/- 1.6 years), 28 had > or = 10 % baseline weight loss, 35 had undergone bariatric surgery (60 % had preoperative mass higher than baseline), and 3 were lost to follow-up; the 34 remaining had lost 1.5 +/- 5.8 kg compared with baseline. During follow-up, 13 had a second intragastric balloon implanted and 13 took sibutramine for short periods. CONCLUSION: Intragastric balloon therapy was relatively innocuous and associated with successful weight loss and maintenance at 2.5 years in a quarter of participants. It represents a valid option for weight loss.

RESUMEN

BACKGROUND AND STUDY AIMS: Bariatric surgical treatments have been proven to induce long-term weight loss in morbidly obese patients, but complications are relatively frequent. We recently reported a first human multicenter trial assessing the safety, feasibility, and weight loss results of the Transoral Gastroplasty (TOGA) system (Satiety Inc., Palo Alto, CA) at 6 months. Here we report the 6-month results of the second phase of the pilot trial with the TOGA system, with technical improvements to the device. PATIENTS AND METHODS: Patients met established criteria for bariatric surgery. The TOGA system, a set of transoral endoscopically guided staplers, was used to create a stapled restrictive pouch along the lesser curvature of the stomach. Follow-up was at 1 week and at 1, 3, and 6 months. At 3 months, re-treatment consisting in additional distal restrictions was allowed if necessary. RESULTS: Data were available for 11 patients in our center (7 female, mean age 44.2 years, mean body mass index 41.6). The procedure was completed safely in all patients. There were no serious adverse events. Mean excess weight loss was 19.2 %, 33.7 %, and 46.0 % at 1, 3, and 6 months, respectively. Average body mass index decreased from 41.6 before treatment to 33.1 at 6 months. Absolute mean weight loss was 9.9 kg, 17.5 kg, and 24.0 kg at 1, 3, and 6 months, respectively. A dramatic improvement in quality-of-life measures was observed in all patients. CONCLUSIONS: This second pilot trial confirmed the feasibility and safety of transoral gastroplasty. The early results and technical improvements reported in the present study are encouraging in terms of safety, early weight loss, and quality of life, and clearly allowed multicenter trials, which are planned to start soon.

RESUMEN

Acute recurrent pancreatitis is a clinical entity largely associated with pancreatic ductal obstruction. This latter includes congenital variants, of which pancreas divisum is the most frequent but also controversial, chronic pancreatitis, tumors of the pancreaticobiliary junction and sphincter of Oddi dysfunction. This review summarizes current knowledge about diagnostic work-up and therapy of these conditions.

RESUMEN

OBJECTIVE: To evaluate the safety and feasibility in human subjects of a new transoral restrictive procedure for the treatment of obesity. METHODS: The protocol was approved by the institutional review boards (IRBs) of both centers involved, and all patients gave informed consent. Patients met established inclusion criteria for bariatric surgery. The TOGa system (Satiety Inc., Palo Alto, CA), a set of transoral endoscopically guided staplers, was used to create a stapled restrictive pouch along the lesser curve of the stomach. Patients were hospitalized overnight for observation and underwent barium upper gastrointestinal (UGI) the next morning. Post procedure, all patients were placed on a liquid diet for 1 month and asked to begin an exercise program. Follow-up was carried out at 1 week and 1, 3, 4, 5, and 6 months. RESULTS: Twenty one patients were enrolled [17 female, age 43.7 (22-57) years, BMI 43.3 (35-53) kg/m(2)]. Device introduction was completed safely in all patients. There were no serious adverse events (AEs). The most commonly reported procedure or device related adverse events were vomiting, pain, nausea, and transient dysphagia. At 6 month endoscopy, all patients had persistent full or partial stapled sleeves. Gaps in the staple line were evident in 13 patients. Patients lost an average 17.6 pounds at 1 month, 24.5 pounds at three months, and 26.5 pounds at 6 months post-treatment [excess weight loss (EWL) of 16.2%, 22.6%, and 24.4%, respectively]. CONCLUSIONS: There is great interest in new procedures for morbid obesity that could offer lower morbidity than current options. Early experience with the TOGa procedure indicates that this transoral approach may be safe and feasible. Further experience with the device and technique should improve anatomic and functional outcomes in the future. Additional studies are underway.

RESUMEN

The vast majority of patients having gastroesophageal reflux disease (GERD) are well-controlled by medical therapy. Surgical treatment is indicated for patients who do not want to take life-long medication, those having persisting symptoms despite PPI therapy or those having atypical symptoms associated with GERD. Although very effective, surgical treatment is loosing part of its efficacy after 10 years and may be associated with chronic or acute complications. This is probably one of the reasons why only a small minority of patients having GERD will ask for surgical therapy. Many endoscopic techniques for treating GERD have been the topic of great enthusiasm over the last 10 years. Most of them, however, have been abandoned either because of severe adverse events, lack of efficacy or non adoption by physicians for routine clinical use. Only few of them have survived and are still used or in development. They include radiofrequency application at the lower esophagus, which is probably indicated in subgroup of patients having symptomatic GERD in the absence of esophagitis and techniques of endoscopic suture which aims to recreate a gastroesophageal valve by endoscopic route. Up to now, most of the published studies dealing with endoscopic treatment of GERD have been focused on patients having typical GERD symptoms who are also those having the highest benefit from PPI therapy. Interestingly, the group which could really benefit from this kind of treatment, namely those patients having persisting symptoms under PPI therapy or those having atypical GERD symptoms have been the topic of much less investigations.
