Role of the gastroenterologist in the management of the obese patient.

2017

Obesity is a highly prevalent disease worldwide, and one in which gastroenterologists can play an important role. Some digestive diseases are more common in obese patients, and preoperative evaluation may be required in some cases. Additionally, bariatric surgery can lead to digestive complications in the short and long term that require intervention, and endoscopic treatment can be an important factor in weight loss. The aim of this review is to highlight the role of the gastroenterologist in the management of obese patients who are either scheduled for or have undergone surgical or endoscopic treatment for obesity.

The use of the endoscope in endodontic surgery : a systematic review

2020

Background A systematic review of clinical studies with at least one year of follow-up was done to assess the success rate of endodontic surgery including endoscopy for magnification and illumination. Material and Methods Five electronic databases were searched, including MEDLINE (via PubMed), Embase, Web of Science, Scopus and the Cochrane Library of the Cochrane Collabora-tion (CENTRAL). There were no language restrictions, and the search covered the period up to October 2019. The risk of bias was evaluated with the Cochrane Collaboration tool for randomized clinical trials and the ROBINS-I tool for non-randomized studies of inter-ventions. Results From the 278 initially identified titles…

Feasibility and Diagnostic Impact of Fluorescence-Based Diagnostic Laparoscopy in Hepatocellular Carcinoma: A Case Report

2002

Fluorescence-based diagnostic techniques are an evolving field in the staging of hepatologic and gastroenterologic malignancies. The method aims at improved accuracy in the detection of locoregional and distant metastases. In hepatocellular carcinoma, detection of metastases is of utmost importance, because advanced tumors preclude curative surgical therapy. We present here our first experience of fluorescence-based diagnostic laparoscopy in a patient with hepatocellular carcinoma. We performed diagnostic laparoscopy in a 76-year-old woman who presented with a tumor of the liver and increased serum levels of alpha-fetoprotein. For photosensitization, 5-aminolevulinic acid (20 mg/kg bodyweig…

Caustic ingestion: CT findings of esophageal injuries and thoracic complications

2020

Ingestion of caustic substances, whether accidental or for the purpose of suicide, can cause severe lesions of the lips, oral cavity, pharynx, upper gastrointestinal system, and upper airways. In particular, caustic agents could be responsible for severe esophageal injuries resulting in short- and long-term complications. Because of these important clinical implications, timely diagnosis and appropriate management are crucial. In the evaluation of esophageal injuries, thoraco-abdominal computed tomography (CT) is preferable to endoscopy as it avoids the risk of esophageal perforation and allows the evaluation of esophageal injuries as well as of the surrounding tissue. In this review, we re…

The stomach in liver cirrhosis

1991

Abstract The stomachs of cirrhotic patients are frequently subject to a number of alterations, detectable by endoscopy, the presence of which indicates a disturbance in the mucosa. Several investigators believe that portal hypertension plays an etiopathogenetic role. Three groups of subjects were studied prospectively: 83 cirrhotic patients with portal hypertension, 53 cirrhotic patients without portal hypertension, and 135 control subjects. Snake skin, scarlatina rash, and petechia were the most frequent endoscopic findings in the cirrhotic patients with portal hypertension ( P

Mini-laparoscopy in the endoscopy unit.

2012

PURPOSE OF REVIEW: The evaluation of liver histology is an important component of the diagnosis and staging of liver diseases. The most common technique employed to sample liver tissue for decades has been percutaneous liver biopsy. Although this is a relatively well tolerated technique in the early stages of liver disease, it carries a high risk of complications, particularly hemorrhage, in patients with advanced cirrhosis. Mini-laparoscopy allows macroscopic assessment and biopsy under direct vision and therefore is a well tolerated and effective technique. RECENT FINDINGS: The major advantages of this technique are direct visualization of the liver surface, thereby allowing inspection fo…

Virtual chromoendoscopy with iSCAN as an alternative method to dye-spray chromoendoscopy for dysplasia detection in long-standing colonic inflammator…

2021

Patients with long-standing colonic inflammatory bowel disease (cIBD) are at increased risk of developing colorectal cancer (CRC). Dye-spray chromoendoscopy (DCE) with targeted biopsies is the preferred technique for surveillance of dysplasia. Virtual chromoendoscopy (VCE) are arising to improve detection rates and adherence to surveillance guidelines, although its role is not yet well defined. The purpose of this study is to assess the effectiveness of VCE with iSCAN as an alternative method for dysplasia detection in cIBD.Retrospective case-control study with 191 patients included, 98 in the DCE (Indigo carmine) group and 93 in the VCE (iSCAN, twin-mode 1-3) group. The dysplasia detection…

Diagnostik der primär sklerosierenden Cholangitis: prospektiver Vergleich von MR-Cholangiographie mit endoskopisch retrograder Cholangiographie

1998

PURPOSE To assess the accuracy of MR cholangiography (MRC) in the diagnosis of primary sclerosing cholangitis (PSC) in comparison to endoscopic retrograde cholangiography (ERC). METHOD 20 patients with PSC were examined by ERC and MRC (1.0 T, HASTE sequence). Visualization and pathologic changes of the extra- and intrahepatic bile ducts were evaluated with both methods. RESULTS Mural irregularities of the common bile duct were seen with MRC in 6/7 cases, stenoses and dilatation of the common bile duct were detected correctly in all patients. Diffuse, multifocal strictures of the intrahepatic bile ducts were the most common intrahepatic findings and correctly diagnosed in almost all patients…
