Recurrent hemobilia secondary to extrahepatic biliary tract cholangiocarcinoma. A diagnostic challenge.

The etiology of hemobilia has mainly iatrogenic (>50%), followed by traumatic causes. Others are biliopathy due to portal high pressure, or neoplastic or infective biliopathy. In the case of non-clear hemobilia, direct-vision-cholangioscopy can change the management in >34% of cases.

Pseudoachalasia as a paraneoplastic event in a patient with Hodgkin's disease.

Pseudoachalasia or secondary achalasia (5% of achalasias that are deemed primary achalasias) is an esophageal motor disorder with manometric criteria for achalasia, but it appears in the context of an underlying pathology that can be attributed to its origin. Usually appears in >60 years with rapid evolution of symptoms (<1 year). The main cause of pseudoachalasia is neoformative etiology, but there are others.

Poor agreement between clinical screening and universal pre-procedure SARS-CoV-2 PCR testing prior to endoscopy.

Introduction: scientific societies recommend screening for SARS-CoV-2 in patients prior to endoscopy. There is no solid evidence regarding the efficiency of universal screening by PCR testing for SARS-CoV-2. The present study aimed to assess the usefulness of clinical screening and universal pre-procedure PCR testing for the identification of patients capable of transmitting the SARS-CoV-2 infection.

Endoscopic management of duodenal levodopa-carbidopa therapy of advanced Parkinson's disease.

Background: treatment of intraduodenal levodopa using percutaneous endoscopic gastrostomy is an alternative therapy in patients with advanced Parkinson's disease. There are few studies that have evaluated the endoscopic aspects of this technique.

Objectives: to describe our experience and adverse events regarding this technique in advanced Parkinson's disease.

[Diagnostic yield of video capsule endoscopy in premenopausal women with iron-deficiency anemia].

Unlabelled: Clinical practice guidelines recommend video capsule endoscopy (VCE) studies in patients with iron-deficiency anemia (IDA) after conventional upper and lower endoscopies but there is a need for studies demonstrating the diagnostic yield, clinical impact, and cost in some patient subgroups.

Objectives: 1.To determine the diagnostic yield of VCE in premenopausal women with IDA compared with that in men and postmenopausal women.
