Diagnosis of malignant biliary obstruction: pondering over the ERCP, MRCP and histology

Objective

To compare the diagnostic accuracy of endoscopic retrograde cholangiopancreatography (ERCP), magnetic resonance pancreatography (MRCP) and histological examination for malignant biliary obstruction.

Methods

This retrospective study included patients admitted for biliary obstruction caused by biliary tree malignancy that underwent ERCP, MRCP and histological examination. Data were collected from the medical records. The primary endpoints were the area under the receiver operating characteristic (AUROC) curve value, sensitivity, specificity and overall diagnostic accuracy of the three procedures in terms of a final diagnosis of obstructive biliary malignancy; and the agreement between ERCP, MRCP and histological examination with the final diagnosis.

Results

A total of 160 patients were included in the study (85 males, 53.1%; mean ± SD age, 69.31 ± 10.96 years). Considering the final diagnosis, the performance of MRCP, ERCP and histology in assessing biliary tumours produced AUROC values of 0.88 (95% confidence interval [CI] 0.75, 0.90), 0.94 (95% CI 0.85, 0.99) and 0.80 (95% CI 0.70, 0.82), respectively. ERCP presented higher sensitivity, overall diagnostic accuracy and agreement with the final diagnosis than MRCP and histological examination.

Conclusion

These current data suggest that invasive methods such as ERCP with biopsy remain more reliable than non-invasive methods.

Opportunistic Colonoscopy Cancer Screening Pays off in Romania-A Single-Centre Study

Colorectal cancer (CRC) is the third most diagnosed cancer in men (after prostate and lung cancers) and in women (after breast and lung cancer). It is the second cause of cancer death in men (after lung cancer) and the third one in women (after breast and lung cancers). It is estimated that, in EU-27 countries in 2020, colorectal cancer accounted for 12.7% of all new cancer diagnoses and 12.4% of all deaths due to cancer. Our study aims to assess the opportunistic colorectal cancer screening by colonoscopy in a private hospital. A secondary objective of this study is to analyse the adenoma detection rate (ADR), polyp detection rate (PDR), and colorectal cancer (CRC) detection rate. We designed a retrospective single-centre study in the Gastroenterology Department of Saint Mary Hospital. The study population includes all individuals who performed colonoscopies in 2 years, January 2019–December 2020, addressed to our department by their family physician or came by themselves for a colonoscopy. One thousand seven hundred seventy-eight asymptomatic subjects underwent a colonoscopy for the first time. The mean age was 59.0 ± 10.9, 59.5% female. Eight hundred seventy-three polyps were found in 525 patients. Five hundred and twenty-five had at least one polyp, 185 patients had two polyps, 87 had three polyps, and 40 patients had more than three polyps. The PDR was 49.1%, ADR 39.0%, advanced adenomas in 7.9%, and carcinomas were found in 5.4% of patients. In a country without any colorectal cancer screening policy, polyps were found in almost half of the 1778 asymptomatic patients evaluated in a single private center, 39% of cases adenomas, and 5.4% colorectal cancer. Our study suggests starting screening colonoscopy at the age of 45. A poor bowel preparation significantly impacted the adenoma detection rate.

Geographic Distribution, Phenotype and Epidemiological Tendency in Inflammatory Bowel Disease Patients in Romania

Background and objective: The incidence of inflammatory bowel disease (IBD) over the past years in Romania has been on the rise, but epidemiologic data are lacking. The aim of this study was to define the characteristics of IBD, the trends and phenotype among IBD patients in Romania. Material and methods: We conducted a prospective study over a period of 12 years, from 2006 to 2017. All patients diagnosed with IBD on clinical, radiological, endoscopic and histological features were included. We divided the country into eight regions: west (W), north-east (NE), north-west (NW), south-east (SE), south-west (SW), south (S), central (C) and Bucharest-Ilfov (B), and data were analyzed accordingly. Results: A total of 2724 patients were included in this database, but only 2248 were included in the final analysis, with all data available. Of the 2248 patients, 935 were Crohn's disease (CD), 1263 were ulcerative colitis (UC) and 50 were IBD-undetermined. In UC phenotypes we observed more frequent left-sided colitis (50.5%, p < 0.0001), and in CD phenotype we observed more frequent colonic and ileo-colonic localization (37.8% and 37.6%, p < 0.0001). The region with the most IBD cases was NE (25.1%) and with the least IBD cases was SW (4.9%). UC was found more frequently in NE (32%), while CD was found more frequently in Bucharest (28.6%). Conclusions: In Romania, ulcerative colitis is more frequent than CD. UC is predominant in the northern part of Romania, while CD has become predominant in the southern part of the country. IBD occurs more in the male population, and in urban and industrialized areas. There are differences between the regions in Romania regarding IBD phenotypes, gender distributions, age distribution, treatment, smoking status and complications.

Malnutrition Prevalence in Newly Diagnosed Patients with Inflammatory Bowel Disease - Data from the National Romanian Database

BACKGROUND AND AIMS

Prevalence of malnutrition in inflammatory bowel diseases (IBD) varies between 16% and 75%. Data on the nutritional status at initial diagnosis of ulcerative colitis (UC) or Crohn's Disease (CD) are scarce. It is believed that more than 50% of IBD patients suffer significant weight loss prior to diagnosis. The aims of our study were to assess malnutrition in patients recently diagnosed with IBD and to determine its predictive factors.

METHODS

We retrospectively included 625 IBD patients registered in the Romanian "IBD Prospect" database between January 2006 and July 2017. All patients were diagnosed within 6 months prior to registration. We defined malnutrition as weight loss of more than 5% of the initial weight during the 3 months prior to registration.

RESULTS

There were 361 new cases of UC, 241 CD and 23 cases of unclassified IBD. There was a slight male predominance (M/F=1.2). Prevalence of overall malnutrition was 36.3%. It was significantly more frequent in CD than in UC patients (41.1% vs. 32.4%, p=0.031). In multivariate analysis, malnutrition in UC patients was associated with male gender (p=0.001), more severe disease (p<0.0001) and more extensive disease (p=0.027), while in CD it was associated with younger age (p=0.013) and more severe disease (p<0.0001).

CONCLUSIONS

About 1 in 3 newly diagnosed IBD patients presents with malnutrition at the time of diagnosis.

Malignant hepatic vascular tumors in adults: Characteristics, diagnostic difficulties and current management

Malignant vascular tumors of the liver include rare primary hepatic mesenchymal tumors developed in the background of a normal liver parenchyma. Most of them are detected incidentally by the increased use of performing imaging techniques. Their diagnosis is challenging, involving clinical and imaging criteria, with final confirmation by histology and immunohistochemistry. Surgery represents the mainstay of treatment. Liver transplantation (LT) has improved substantially the prognosis of hepatic epithelioid hemangioendothelioma (HEHE), with 5-year patient survival rates of up to 81%, based on the European Liver Intestine Transplantation Association-European Liver Transplant Registry study. Unfortunately, the results of surgery and LT are dismal in cases of hepatic angiosarcoma (HAS). Due to the disappointing results of very short survival periods of approximately 6-7 mo after LT, because of tumor recurrence and rapid progression of the disease, HAS is considered an absolute contraindication to LT. Recurrences after surgical resection are high in cases of HEHE and invariably present in cases of HAS. The discovery of reliable prognostic markers and the elaboration of prognostic scores following LT are needed to provide the best therapeutic choice for each patient. Studies on a few patients have demonstrated the stabilization of the disease in a proportion of patients with hepatic vascular tumors using novel targeted antiangiogenic agents, cytokines or immunotherapy. These new approaches, alone or in combination with other therapeutic modalities, such as surgery and classical chemotherapy, need further investigation to assess their role in prolonging patient survival. Personalized therapeutic algorithms according to the histopathological features, behavior, molecular biology and genetics of the tumors should be elaborated in the near future for the management of patients diagnosed with primary malignant vascular tumors of the liver.

Diagnosis and Treatment of Colonic Diverticular Disease: Position Paper of the Romanian Society of Gastroenterology and Hepatology

BACKGROUND AND AIMS

Diverticular disease of the colon is a common clinical condition in developed countries, and is associated with significant (direct and indirect) economic burden. The aim of this Position Paper is to provide clinical guidance for appropriate definition, prevalence, risk factors, diagnosis, and treatment of colonic diverticular disease.

METHODS

A working group of recognized experts established by the Board of the Romanian Society of Gastroenterology and Hepatology (RSGH) screened the literature and the available guidelines on colonic diverticular disease. Statements were formulated based on literature evidence. These statements were discussed within the working group and decision for each of them was taken by consensus.

RESULTS

Thirty two statements were elaborated. The grade of recommendation, according to the level of evidence was established for each statement. Short comments with literature support accompany each statement.

CONCLUSION

This Position Paper represents a practical guide for clinicians dealing with patients affected by colonic diverticular disease.

Prognostic significance of tumor immune microenvironment and immunotherapy: Novel insights and future perspectives in gastric cancer

Despite a decrease in gastric cancer incidence, the development of novel biologic agents and combined therapeutic strategies, the prognosis of gastric cancer remains poor. Recently, the introduction of modern immunotherapy, especially using immune checkpoint inhibitors, led to an improved prognosis in many cancers. The use of immunotherapy was also associated with manageable adverse event profiles and promising results in the treatment of patients with gastric cancer, especially in heavily pretreated patients. These data have led to an accelerated approval of some checkpoint inhibitors in this setting. Understanding the complex relationship between the host immune microenvironment and tumor and the immune escape phenomenon leading to cancer occurrence and progression will subsequently lead to the identification of prognostic immune markers. Furthermore, this understanding will result in the discovery of both new mechanisms for blocking tumor immunosuppressive signals and pathways to stimulate the local immune response by targeting and modulating different subsets of immune cells. Due to the molecular heterogeneity of gastric cancers associated with different clinico-biologic parameters, immune markers expression and prognosis, novel immunotherapy algorithms should be personalized and addressed to selected subsets of gastric tumors, which have been proven to elicit the best clinical responses. Future perspectives in the treatment of gastric cancer include tailored dual immunotherapies or a combination of immunotherapy with other targeted agents with synergistic antitumor effects.

Mucosal Protective Compounds in the Treatment of Gastroesophageal Reflux Disease. A Position Paper Based on Evidence of the Romanian Society of Neurogastroenterology

Background & Aims: Gastroesophageal reflux disease (GERD) therapy is challenging and suppression of acid secretion or prokinetics do not cure all cases. Some drugs with protective action on the esophageal mucosa have been used alternatively or in association with proton pump inhibitors (PPIs) and/or prokinetics. The Romanian Society of Neurogastroenterology undertook an Evidence-Based analysis, from which this position paper evolved. Methods: We performed a systematic literature search in PubMed until October 2015, using the terms: sucralfate, guaiazulene, gaiazulene, dimethicone, alginate, antacids and gastroesophageal reflux. Forty-seven papers were included and analyzed. Several statements were elaborated regarding the use of these drugs in GERD. The evidence and recommendations were discussed between the authors. Results: There is evidence in the medical literature suggesting the benefit of these drugs in GERD. In patients with persistent or mild reflux symptoms antacids rapidly relieve heartburn. Alginate-antacid combination is superior both over placebo and antacids to treat mild reflux symptoms, and can be used to treat persistent reflux symptoms despite acid suppressant therapy. Sucralfate is superior over placebo in alleviating GERD symptoms and can be used as maintenance therapy. Guaiazulene-dimethicone improves the quality of life in patients with GERD. Conclusions: Drugs used to protect the esophageal mucosa against acid are useful in alleviating chronic heartburn, especially in patients with mild reflux symptoms.
