Use of stool molecular panel in hospitalized patients with diarrhea. Experience in a tertiary care center.

Infectious diarrhea is a common health issue that affects a large number of individuals each year. It causes significant morbidity and mortality, greatly impacting healthcare system costs. Rapid detection of the causative organism and timely treatment alters the management and outcome of the condition.

Usefulness of a mobile app to improve performance of specialists in responding correctly to CRC screening and surveillance clinical scenarios.

The adherence to and knowledge of physicians about colorectal cancer (CRC) screening and surveillance guidelines is still suboptimal, threatening the effectiveness of CRC screening. This study assessed the usefulness of a mobile decision support system (MDSS) to improve physician ability to recommend proper timing of and intervals for CRC screening and surveillance. This was a binational, single-blinded, randomized clinical trial including gastroenterologists and colorectal surgeons from Argentina and Uruguay.

Rapid diagnosis of mucinous cystic pancreatic lesions by on-site cyst fluid glucometry.

Introduction: Available intracystic biomarkers show a limited accuracy for characterizing cystic pancreatic lesions (CPL). Glucose is an attractive alternative due to its availability, low cost and the possibility of on-site quantification by glucometry.

Aim: To evaluate the diagnostic accuracy of on-site glucometry from samples obtained by EUS-FNA in the differential diagnosis between mucinous from non-mucinous CPL.

Primary lymphoma of the entire esophagus diagnosed by endoscopic ultrasound-guided fine needle aspiration (EUS-FNA).

Primary esophageal lymphoma is extremely rare, with fewer than 30 cases reported in the literature. Presentation is nonspecific with multiple radiological and endoscopic appearances, posing its diagnosis a challenge. We report a case of a primary esophageal lymphoma diagnosed by endoscopic ultrasound-fine needle aspiration in a 68-year-old woman referred to our hospital for evaluation of a submucosal tumor spreading all over the esophageal wall.

Endoscopic Ultrasound in the Diagnosis of Pancreatoduodenal Groove Pathology: Report of Three Cases and Brief Review of the Literature.

The pancreatoduodenal groove is a small area where pathologic processes involving the distal bile duct, duodenum, pancreatic head, ampulla of Vater, and retroperitoneum converge. Despite great advances in imaging techniques, a definitive preoperative diagnosis is challenging because of the complex anatomy of this area. Therefore, surgical intervention is frequently required because of the inability to completely exclude malignancy.

[Gastrointestinal bleeding and intestinal perforation due to polyarteritis nodosa in a patient with celiac disease. A case report].

Complications of celiac disease could present with intestinal perforation and rarely, gastrointestinal bleeding, which are usually secondary to nongranulomatous ulcerative jejunoileitis or T-cell lymphoma. We describe the case of a 66-year-old male patient with an 8-year history of celiac disease (CD) who presented with recurrent abdominal pain and gastrointestinal bleeding. Several tests were performed to find out possible complications associated to CD.

Endoscopic management of biliary complications after adult living-donor versus deceased-donor liver transplantation.

Background: Although data about the incidence and management of biliary complications after deceased-donor liver transplantation (DDLT) are well defined, those pertaining to adult living-donor liver transplantation (LDLT) are conflicting.

Methods: We retrospectively compared endoscopic retrograde cholangio-pancreatography (ERCP) findings in 30 LDLT vs. 357 DDLT consecutive adult recipients with duct-to-duct biliary reconstruction.

Grasp or brush for biliary sampling at endoscopic retrograde cholangiography? A blinded randomized controlled trial.

Objectives: Brushing, the standard sampling method at endoscopic retrograde cholangiography (ERC), lacks sensitivity for cancer detection. We assessed a novel sampling method using a grasping basket.

Methods: Fifty-six patients with a suspected malignant biliary stricture were randomized to biliary sampling at ERC using a basket (basket group, N = 30) or a brush (brush group, N = 26), followed by the alternate device.

Uninvestigated dyspepsia in Latin America: a population-based study.

We sought to assess the prevalence, severity of symptoms, and risk factors of uninvestigated dyspepsia in a population-based study in Argentina. Eight hundred thirty-nine valid questionnaires were evaluated. Dyspepsia was present in 367 subjects (43.

Long-term outcome of argon plasma ablation therapy for bleeding in 100 consecutive patients with colonic angiodysplasia.

Purpose: Angiodysplasia is a frequent cause of colonic bleeding. Argon plasma coagulation was reported to be useful in endoscopic hemostasis. However, the long-term outcomes have been poorly evaluated.

Argon plasma coagulation for prevention of recurrent bleeding from GI angiodysplasias.

Background: Angiodysplasia is a frequent cause of GI bleeding. Argon plasma coagulation has been shown to arrest bleeding, but its efficacy for prevention of recurrent bleeding has not been thoroughly evaluated. This study assessed the effectiveness and the safety of argon plasma coagulation for prevention of recurrent bleeding from GI angiodysplasias.
