Endoscopic ultrasound (EUS) is a widely used imaging modality for both diagnostic and therapeutic purposes. Understanding the anatomy is crucial during a curved linear EUS examination. Compared with other advanced endoscopic techniques, the learning curve for EUS is longer, and the training facilities for EUS are also not widely available. The interest and enthusiasm for EUS among endoscopists is limited by the long learning curve and the scarcity of training programs. Imaging of the pancreas is the most common indication of EUS examination, and many endoscopist often face difficulty in understanding the anatomy and orientation of the pancreas on linear EUS examination. In this article, we will discuss the problems encountered during linear EUS examination and how to overcome each problem with a station-wise pancreas examination.

Endoscopic biliary stent placement is a well-established, safe, and minimally invasive modality for the treatment of choledocholithiasis and other biliary diseases. Over the past decade, there has been an increase in its prevalence and use. We present an unusual case of forgotten biliary stent for 17 years who presented now with gangrenous cholecystitis and sealed the perforation. A large stentolith had also developed which was cleared with endoscopic retrograde cholengiography and re-stenting followed by laparoscopic cholecystectomy.

Among 1000 retrosternal chest pain patients, 450(45%) cardiovascular, 255(25.5%) respiratory, 248(24.85%) upper GI and 47(0.47%) had other system involvement. Among 248 GI patients, the frequency of symptoms was as follows: Pinpoint localized odynophagia (8.46%), non-localised odynophagia (12.09%), nausea (62.09%), vomiting (44.35%), dysphagia (3.62%), dyspepsia (13.70%) and hematemesis (0.8%). PLO, dysphagia, and hematemesis were significant symptoms of PIO (p<0.05). Endoscopic findings suggestive of PIO such as kissing ulcer, multiple small discrete ulcers, oesophageal erosions were observed in 91.30%, 47.83%, and 34.78% patients, respectively. Involvement of the middle third of esophagus was present in 74.19% and the lower third in 25.81% patients. Most of the patients with PLO had kissing oesophageal ulcer seen on endoscopy (pvalue =0.0002). The habit of consuming pill with less than 100 ml of water and consumption of night pill dose 10 minutes or less before sleeping were observed as significant risk factors for PIO (p value<0.05). PLO is a newly established and highly specific symptom of PIO of our study and it matches with kissing ulcer of the esophagus by endoscopy.
