Esophageal lichen planus: An unusual cause of dysphagia in the elderly.

An 82-year-old man sought our service with dysphagia and was referred for upper endoscopy with biopsies, which evidenced multiple ulcers of the esophagus and oropharinx. Histopathology confirmed the unusual diagnosis of esophageal lichen planus. The correct clinical suspicion of this disease can facilitate the diagnosis and guide specific treatment, which can drastically change the natural course of the disease.

Minimally invasive endoscopic treatment of necrotizing pancreatitis: A case report with images and review of the literature.

Necrotizing pancreatitis with fluid collections can occur as a complication of acute pancreatitis. The management of these patients depends on the severity and involves multiple medical treatment modalities, as clinical intensive care and surgical intervention. In this article, we show a severe case of walled-off pancreatic necrosis that was conducted by endoscopic drainage with great clinical outcome.

Rapid on-site cytopathological examination (ROSE) performed by endosonagraphers and its improvement in the diagnosis of pancreatic solid lesions.

Purpose: To evaluate the diagnosis improvement of EUS-FNA when using ROSE performed by the endosonographer.

Methods: A retrospective study was conducted. A total of 48 pancreatic solid masses EUS-FNA were divided into two groups according to the availability of on-site cytology (ROSE) - the first 24 patients (group A-without ROSE) and the latter 24 cases (group B-with ROSE).

Rectal cancer staging: Correlation between the evaluation with radial echoendoscope and rigid linear probe.

Background And Objectives: The National Cancer Institute estimated 40,340 new cases of rectal cancer in the United States in 2013. The correct staging of rectal cancer is fundamental for appropriate treatment of this disease. Transrectal ultrasound is considered one of the best methods for locoregional staging of rectal tumors, both radial echoendoscope and rigid linear probes are used to perform these procedures.
