Gastroesophageal reflux disease (GERD) is one of the most prevalent gastrointestinal disorders. The key feature of GERD is reflux of gastric contents into the esophagus. Medical treatment with proton-pump inhibitors (PPIs) is well established and is considered the standard treatment. Given the high prevalence of the condition and the excellent response to medical therapy, antireflux surgery is an option for patients with volume reflux that is not properly controlled by medical therapy. Adenocarcinoma is a rare but life-threatening complication of GERD. The only known precursor lesion for esophageal adenocarcinoma is Barrett's esophagus. In recent years, a clearer understanding of the development of Barrett's and of its progression toward invasive cancer has developed. Genetic factors almost certainly determine the individual risk. The length of the Barrett's esophagus segment and the size of a hiatal hernia are associated with the risk of developing high-grade dysplasia and esophageal adenocarcinoma.With regard to the clinical management of GERD patients with Barrett's, endoscopic surveillance at 3-year intervals is now considered appropriate in the absence of dysplasia. In patients with high-grade dyspepsia, the situation is more difficult. While a considerable proportion of these patients may already have invasive cancers, there is also the possibility that there is only focal dysplasia. For this reason, it is justifiable to carry out curative endoscopic resection. Mucosal ablation procedures may also be appropriate, but these still need to be properly investigated in clinical trials.

Intraductal papillary mucinous neoplasms include a large spectrum of lesions communicating with the Wirsung duct, having a variable invasiveness from benign or borderline, to malignant (carcinoma in situ and invasive cancer). Final diagnosis is based on endoscopic ultrasound (EUS)-guided fine needle aspiration and histopathologic exam of surgical specimens. We present the case of a 28-year-old woman, with several episodes of acute recurrent pancreatitis in the past 6 months, admitted for dyspepsia, nausea and loss of appetite. Imaging studies (transabdominal ultrasonography, CT scanning, MR cholangiopancreatography) showed a macrocystic, multilocular, corporeal tumor, communicating with the retrograde dilated Wirsung duct. EUS revealed hypoechoic material inside the cysts, raising the suspicion of an intraductal papillary mucinous neoplasm. Diagnosis was confirmed by EUS-guided fine needle aspiration, which found columnar mucinous cells within a mucin-rich fluid. The imaging evaluation was repeated after two years, showing a rapid evolution of the tumor. The patient refused surgical exploration and caudal pancreatectomy. In the context of the absence of clinical symptoms, the indolent evolution of these tumors and the excellent prognosis after resection, we consider that early identification and regular follow-up by EUS with fine needle aspiration is imperative, especially because of the limited success of other imaging methods.
