RESUMEN
Background and Objectives: Biologic therapy has fundamentally changed the opportunity of medical treatment to induce and maintain remission in inflammatory bowel disease (IBD). Nevertheless, the rate of surgery is still at a very high rate, profoundly affecting the quality of life. We aimed to analyze surgical cases at three major IBD units in order to identify the main risk factors and the impact of biologic therapy on pre- and postsurgical outcomes. Material and Methods: This was a multicenter retrospective cohort study that included 56 patients with IBD-related surgical interventions from 3 tertiary care hospitals in Bucharest, Romania. The study was conducted between January 2017 and June 2021. All data were retrospectively collected from the medical records of the patients and included the age at diagnosis, age at the time of surgery, IBD type and phenotype, biologic therapy before or/and after surgery, timing of biologic therapy initiation, extraintestinal manifestations, type of surgery (elective/emergency), early and long-term postoperative complications and a history of smoking. Results: A low rate of surgical interventions was noted in our cohort (10.3%), but half of these occurred in the first year after the IBD diagnosis. A total of 48% of the surgical interventions had been performed in an emergency setting, which seemed to be associated with a high rate of long-term postoperative complications. We found no statistically significant differences between IBD patients undergoing treatments with biologics before surgery and patients who did not receive biologics before the surgical intervention in terms of the IBD phenotype, type of surgery and postoperative complications. Conclusion: Our study showed that biologics initiated before the surgical intervention did not influence the postoperative complications. Moreover, we demonstrated that patients with Crohn's disease and no biologics were the most susceptible to having to undergo surgery. Conclusion: In conclusion, the management of patients with IBD requires a multidisciplinary approach that considers an unpredictable evolution.

INTRODUCTION: Pancreatic malignancies represent highly fatal diseases with poor prognosis and constantly increasing incidence despite modern diagnostic and therapeutic options. Both endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) are regarded as mainstays in pancreatic cancer management. The present study aims to evaluate whether accuracy EUS with fine-needle aspiration or biopsy (FNA or FNB) in pancreatic cancer diagnosis is influenced by prior biliary stenting or by technical or anatomical features (stent type, number of needle passes, common bile duct or Wirsung's diameter, topographical characteristics and diameter of the pancreatic tumor). MATERIALS AND METHODS: This retrospective study includes 243 patients with pancreatic cancer who underwent ERCP and EUS with fine-needle aspiration or biopsy (FNA or FNB). RESULTS AND DISCUSSION: Out of the total number of patients, 68 were stented prior to EUS. We found that the EUS-FNA diagnostic yield is not influenced either by the presence of biliary stent, nor by the type of stent (plastic or metallic). Moreover, the mean needle passes required were similar for both stented patients and not stented ones. CONCLUSIONS: Ultimately, given our results, we can state that EUS-FNA/FNB can be safely and accurately performed in the presence of biliary stents.

Introduction: Acute pancreatitis (AP) represents a major burden for the medical system, associating important morbidity and mortality rates. This paper is focused on debatable aspects of the management of biliary AP, namely indications, timing and outcomes of endoscopic retrograde cholangiopancreatography (ERCP) on the hand and, on the other hand, same-admission cholecystectomy as a preventive measure for recurrent disease. Material and methods: This is a retrospective study including 108 patients with biliary AP in whom ERCP was performed, treated in the Clinical Emergency Hospital of Bucharest between 2016 and 2020. According to the urgency of the ERCP, we divided the patients into two groups: urgent versus delayed ERCP. Results: Urgent ERCP was performed in 52 patients, while delayed ERCP was performed in 56 patients; the hospital stay was higher in the urgent group than in the delayed group (10 days vs 8 days, p = 0.299) with no difference in morbidity rates. The mean time between ERCP and surgery was 5 days, without significant difference between the groups. The laparoscopic approach was the preferred method, with a conversion rate of 7%. Conclusion: ERCP with stone extraction followed by same-admission laparoscopic cholecystectomy is a safe therapeutic option, that prevents recurrent pancreatitis. The timing of the procedures remains debatable, further prospective studies being needed to achieve statistical significance.

Cholangiocarcinoma (CCA) is an adenocarcinoma originating from the epithelial cells of the bile ducts/hepatocytes or peribiliary glands. There are three types of cholangiocarcinoma: intrahepatic, perihilar and distal. CCA represents approximately 3% of the gastrointestinal malignancies. The incidence of CCA is higher in regions of the Eastern world compared to the Western countries. There are multiple risk factors associated with cholangiocarcinoma such as liver fluke, primary sclerosing cholangitis, chronic hepatitis B, liver cirrhosis and non-alcoholic fatty liver disease. Endoscopy plays an important role in the diagnosis and management of cholangiocarcinoma. The main endoscopic methods used for diagnosis, biliary drainage and delivering intrabiliary local therapies are endoscopic retrograde cholangiopancreatography and endoscopic ultrasound. The purpose of this review is to analyze the current data found in literature about cholangiocarcinoma, with a focus on the actual diagnostic tools and endoscopic management options.
RESUMEN
Liver transplantation represents the definitive intervention for various etiologies of liver failure and encompasses a spectrum of rare indications crucial to understanding the diverse landscape of end-stage liver disease, with significantly improved survival rates over the past three decades. Apart from commonly encountered liver transplant indications such as decompensated cirrhosis and liver cancer, several rare diseases can lead to transplantation. Recognition of these rare indications is essential, providing a lifeline to individuals facing complex liver disorders where conventional treatments fail. Collaborative efforts among healthcare experts lead not only to timely interventions but also to the continuous refinement of transplant protocols. This continued evolution in transplant medicine promises hope for those facing diverse and rare liver diseases, marking a paradigm shift in the landscape of liver disease management.
RESUMEN
Monitoring disease activity in inflammatory bowel disease (IBD) is challenging since clinical manifestations do not represent reliable surrogates for an accurate reflection of the inflammatory burden. Endoscopic remission had been the most significant endpoint target in the last years; nevertheless, a remarkable proportion of patients continue to relapse despite a normal-appearing mucosa, highlighting that endoscopy may underestimate the true extent of the disease. A subtle hint of the importance that histology plays in the long-term course of the disease has been endorsed by the STRIDE-II consensus, which recommends considering histologic healing for ulcerative colitis (UC), even though it is not stated to be a compulsory formal target. It is a continuum-changing paradigm, and it is almost a certainty that in the near future, histologic healing may become the new formal target for ulcerative colitis. It must be emphasized that there is great heterogeneity in defining histological remission, and the main criteria or cut-off values for inflammatory markers are still in an ill-defined area. The complexity of some histologic scores is a source of confusion among clinicians and pathologists, leading to low adherence in clinical practice when it comes to a homogenous histopathological report. Therefore, a standardized and more practical approach is urgently needed.
RESUMEN
Artificial intelligence (AI) is a term that covers a multitude of techniques that are used in a manner that tries to reproduce human intelligence. AI is helpful in various medical specialties that use imaging for diagnostic purposes, and gastroenterology is no exception. In this field, AI has several applications, such as detecting and classifying polyps, detecting the malignancy in polyps, diagnosing Helicobacter pylori infection, gastritis, inflammatory bowel disease, gastric cancer, esophageal neoplasia, and pancreatic and hepatic lesions. The aim of this mini-review is to analyze the currently available studies regarding AI in the field of gastroenterology and hepatology and to discuss its main applications as well as its main limitations.
RESUMEN
Duodenal gangliocytic paragangliomas are rare neuroendocrine tumors primarily localized in the periampullary area. Though mostly asymptomatic, they can present with various symptoms, most often jaundice, anemia and abdominal pain. The present paper is a case series report, describing our personal experience with patients presenting to the Emergency Unit with different symptoms due to duodenal gangliocytic paraganglioma. Endoscopic resection is safe and indicated in most of the cases, being also associated with lower medical costs. EUS plays a central role in the pre-resection management and in surveillance, and immunostaining is decisive to ascertain the tumor histologic origin. In addition to reporting our experience, we researched the literature regarding these rare tumors and performed a comprehensive review.
RESUMEN
Introduction/Aim. The aim of this study was to assess the prevalence of cognitive impairments and their association with sleep patterns in a cohort of patients diagnosed with chronic liver disease (CLD). Material and methods. The present paper is a prospective cohort study, carried out over a period of 12 months, among patients with various stages of CLD. We evaluated the cognitive function through psychometric hepatic encephalopathy score (PHES), while sleep was assessed by actigraphy and two self-reported questionnaires: Epworth Sleepiness Scale (ESS) and Pittsburgh Sleep Quality Index (PSQI). Results. Seventy-four patients with CLD were considered eligible and were enrolled between December 2020−November 2021. The prevalence of minimal hepatic encephalopathy (MHE) in the entire cohort was 41.9%, and the diagnosis was considered for PHES scores ≤ −3. Patients with cirrhosis recorded significantly lower PHES scores compared to patients with other CLDs but without cirrhosis (−3.19 ± 3.89 vs. 0.19 ± 2.92, p < 0.05). Patients who exhibited MHE suffered from poor sleep, daytime somnolence, disturbed nighttime sleep, and low overall sleep efficacy. Patients diagnosed with MHE and undergoing treatment with lactulose and/or rifaximin for prevention of overt hepatic encephalopathy (HE) showed better results in terms of sleep parameters compared to patients diagnosed with MHE but without treatment. Conclusions. This research increases awareness regarding the connection between sleep features and MHE in patients with cirrhosis and other CLDs. A deeper insight into the subclinical stages of HE and associated sleep disturbances is warranted in future studies.
RESUMEN
Background and Aim. Endoscopic therapy is the method of choice in the management of biliary strictures after orthotopic liver transplantation (OLT). Even though the mainstay approach for OLT stricture complications is represented by consecutive procedures of multiple plastic stents (MPS) insertion, a valuable alternative is the use of fully covered self-expandable metal stents (FCSEMS). The aim of the study was to compare MPS with FCSEMS used in the management of OLT biliary strictures, in terms of clinical outcomes and complications. Material and Methods. This is a retrospective, single-center study conducted between February 2014 and November 2019 in the Clinical Emergency Hospital of Bucharest, Romania. We enrolled all consecutive patients who developed biliary strictures after OLT and were treated by endoscopic retrograde cholangiopancreatography (ERCP) either with MPS or FCSEMS. Results. Thirty-six patients were included in the study, 27 patients had MPS and nine patients had FCSEMS. 106 ERCP procedures were performed and 159 stents were inserted. The mean number of ERCP procedures required per patient was significantly higher for MPS than for FCSEMS (3.34 ± 1.46 vs. 2.11 ± 0.33, p < 0.001). In the FCSEMS group only one patient had three procedures, due to stent migration. Difficult cannulation was encountered in 22 patients, 18 patients from MPS group and four patients from FCSEMS group. Dilation was performed in 20 (77%) MPS patients and in four FCSEMS patients (44%). Overall, we used 159 stents for stricture resolution, 149 plastic stents and 10 FCSEMS. Mean number of stents inserted was significantly lower in the FCSEMS group compared to MPS group (1.16 ± 0.40 vs. 5.73 ± 2.64, p < 0.001). Conclusions. Stricture resolution using FCSEMS is comparable to MPS and even has some advantages. In line with prior studies, FCSEMS are effective, with fewer complications and similar outcome compared to plastic stents. Other particular aspects should be further assessed, especially long-term follow up of FCSEMS and their cost efficiency.
RESUMEN
INTRODUCTION AND AIM: Sleep disorders are highly prevalent in patients with liver cirrhosis. The aim of this study was to investigate the prevalence of restless legs syndrome (RLS), as well as its risk factors and possible predictors, in a cohort of patients with liver cirrhosis. MATERIAL AND METHODS: We performed a cross-sectional prospective study over a period of 14 months and enrolled 69 patients with liver cirrhosis, after applying the inclusion and exclusion criteria. The cases of RLS were assessed according to the International Restless Legs Syndrome Study Group (IRLSSG) criteria and severity scale. RESULTS: Out of the total number of patients, 55% fulfilled the criteria for RLS. Age, diabetes, severity of cirrhosis, serum creatinine, glomerular filtration rate (GFR), and mean hemoglobin were associated with the presence of RLS. Moreover, there was a significantly higher prevalence of RLS among patients with decompensated cirrhosis. From all the risk factors introduced into the multivariate analysis, only the GFR could predict the presence of RLS. CONCLUSIONS: This research shows that patients with liver cirrhosis have a high risk of RLS. Even though there are multiple risk factors associated with RLS, only the GFR could predict its occurrence in our cohort.
RESUMEN
BACKGROUND: Cholangiocarcinoma is the most common malignancy of the bile ducts causing intrahepatic, hilar, or distal bile duct obstruction. Most jaundiced patients are diagnosed with unresectable tumors in need for palliative bile duct drainage and chemotherapy. Endobiliary radiofrequency ablation (RFA) is an adjuvant technique that may be applied prior to biliary stenting. The aim of our study was to assess the efficacy of endobiliary RFA prior to stent insertion in patients with unresectable distal cholangiocarcinomas. METHODS: Twenty-five patients (eight treated with RFA and stenting and 17 treated with stenting alone) were included in a case-controlled study. We prospectively assessed the impact of RFA on the survival rate, the patient performance status, and the preservation of eligibility for chemotherapy based on the patient laboratory profile. RESULTS: Patients treated with RFA prior to stenting proved to have a significantly longer survival interval (19 vs. 16 months, p = 0.04, 95% CI) and significantly better performance status. Moreover, the laboratory profiles of patients treated with RFA has been proven superior in terms of total bilirubin, liver enzymes, and kidney function, thus making patients likely eligible for palliative chemotherapy. Post-ERCP adverse events were scarce in both the study group and the control group. CONCLUSION: Given the isolated adverse events and the impact on the patient survival, performance, and laboratory profile, RFA can be considered safe and efficient in the management of patients with unresectable distal cholangiocarcinomas.
RESUMEN
The present study aims to assess the sleep characteristics and health-related quality of life (HRQOL) among patients with chronic liver diseases (CLDs), as well as the relationship between them. We conducted a prospective cross-sectional study, over a period of eight months, on patients with CLDs. Sleep was assessed by subjective tools (self-reported validated questionnaires), semi-objective methods (actigraphy), and HRQOL by using the 36-Item Short Form Survey (SF-36) and Chronic Liver Disease Questionnaire (CLDQ). The results indicated that 48.21% of patients with CLDs had a mean Pittsburgh Sleep Quality Index (PSQI) score higher than five, suggestive of poor sleep; 39.29% of patients had a mean Epworth Sleepiness Scale (ESS) score ≥11, indicative of daytime sleepiness. Actigraphy monitoring showed that patients with cirrhosis had significantly more delayed bedtime hours and get-up hours, more awakenings, and more reduced sleep efficacy when compared to pre-cirrhotics. The CLDQ and SF-36 questionnaire scores were significantly lower in cirrhotics compared to pre-cirrhotics within each domain. Moreover, we identified significant correlations between the variables from each questionnaire, referring to HRQOL and sleep parameters. In conclusion, sleep disturbances are commonly encountered among patients with CLDs and are associated with impaired HRQOL. This is the first study in Romania that assesses sleep by actigraphy in a cohort of patients with different stages of CLD.
RESUMEN
The impact of sleep disorders (SDs) on patients with chronic liver diseases (CLD) is tremendous. SDs are frequently encountered among these patients and interfere with their quality of life. This review aims to present the data available so far about the prevalence, phenotypes, and proposed pathophysiological mechanisms of SDs in CLD. Moreover, we proposed to search the literature regarding the most reliable methods to assess SDs and the possible therapeutic options in patients with CLD. The main results of this review show that when it comes to prevalence, the percentages reported vary widely between studies performed among populations from the USA or Europe and those coming from Asian countries. Furthermore, it has been proven that SDs may also be present in the absence of neurocognitive disorders attributable to hepatic encephalopathy (HE), which contradicts traditional suppositions where SDs were considered part of the clinical scenario of HE. Currently, there are no specific recommendations or protocols to assess SDs in CLD patients and data about the therapeutic management are limited. Taking into consideration their impact, a protocol for diagnosing and managing SDs should be developed and included in the daily practice of hepatologists.
RESUMEN
OBJECTIVE: The purpose of this study was to present the experience of a single center on endoscopic ultrasound-fine-needle biopsy (EUS-FNB) of pancreatic solid tumors amenable to immunohistochemistry (IHC) assay. PATIENTS, MATERIALS AND METHODS: Inclusion criterion for this prospective study was identifying patients with pancreatic solid tumors, by means of imaging methods, from January 2018 to February 2020, within the Department of Gastroenterology, Emergency Clinical Hospital, Bucharest, Romania. All patients underwent EUS-FNB and the harvested tissue was sent to the Department of Pathology for histopathological (HP) diagnosis and IHC assessment if tumoral origin remained undetermined. RESULTS: A total of 57 patients were ultimately selected to take part in our study. We performed immunohistochemical analysis based on the morphological diagnosis of the pancreatic tumors and assessed cytokeratin (CK)7, CK20, caudal type homeobox 2 (CDX2), MutL homolog 1 (MLH1), MutS homolog (MSH)2, MSH6, postmeiotic segregation 2 (PMS2) for all histopathologically uncertain pancreatic ductal adenocarcinoma (PDAC) and chromogranin A, synaptophysin, pan-CK AE1∕AE3 for pancreatic neuroendocrine tumors (pNETs). Cox hazard regression was performed to identify the factors influencing the survival rate. In univariate analysis, patient survival time was significantly associated with stage, location, surgical management and CK7 positivity. Our data show a statistically significant predictive relationship between stage (regional or metastatic) and hazard for survival (p=0.015). Tumoral location in the tail (p=0.015) and radicality surgery (p=0.015) significantly decrease the survival of pancreatic cancer (PAC) patients. The presence of CK7 (p=0.015) significantly increases the survival of pancreas cancer patients. CONCLUSIONS: EUS-FNB has opened up a new path for pancreatic tumor diagnosis providing enough tissue for HP examination and IHC. A panel of several immunomarkers might aid in providing new therapies for PAC patients.
