The management of Barrett's esophagus and early esophageal adenocarcinoma has shifted away from esophagectomy and toward endoscopic techniques, including endoscopic resection and ablative therapies. The most commonly used ablative therapies are radiofrequency ablation and cryotherapy. Radiofrequency ablation has risen to the top of the management algorithm due to its favorable safety profile and established track record of efficacy in patients with dysplastic Barrett's. Cryotherapy offers early promise as an alternatively safe and effective ablative modality...

INTRODUCTION: We are a reporting on the indications, techniques, and limitations of robotic surgery in the management of renal stones disease. Robotic surgery is a good tool to manage large kidney and ureteral stones, particularly in patients with anatomic anomalies. We describe three techniques in managing staghorn kidney stones: robotic anatrophic nephrolithotomy, robotic pyelolithotomy, and robotic nephrolithotomy. MATERIAL AND METHODS: Robotic pyelolithotomy (RP) is ideal for patients with large renal pelvis and partial staghorn stone with a wide extra-renal pelvis...

Large bowel obstruction secondary to colonic gallstone impaction is rare. We report an elderly patient who presented with colonic obstruction secondary to impaction of a gallstone in a diverticular segment of his sigmoid colon. He had severe comorbidities that precluded surgery, and it was not possible to remove the gallstone using standard endoscopic techniques. Endoscopic electrohydraulic lithotripsy (EHL) was performed to fracture the gallstone, and fragments were successfully removed. For comorbid patients who are not fit for general anesthesia, endoscopic stone retrieval should be considered...

Background: Endoscopic full thickness resection (EFTR) by the Full Thickness Resection Device (FTRD) has recently been introduced as a method to allow resection of certain lesions such as adenomatous polyps that would not be resectable by standard polypectomy techniques. We report our clinical experience with FTRD procedures, assessing technical success, completeness of resection (R0 status), rate of histologically proven FTR and safety. Patients and methods: We conducted a retrospective analysis of 33 consecutive patients with colonic polyps treated with FTRD from May 2015 to November 2016...

The paper presents a description of the course of severe acute necrotizing pancreatitis as well as endoscopic treatment of an extensive infected walled-off pancreatic necrosis (WOPN), being the consequence of acute pancreatitis. The basic strategy of interventional treatment was to extend access to necrotic areas with use of single transluminal gateway transcystic multiple drainage (SGTMD). Endoscopic transmural access (transgastric) was applied. Endoscopic necrosectomy under fluoroscopic guidance was repeated nine times during active transluminal drainage...

REVIEW
Hua Gao, Chunhui Liu, Yazhuo Zhang
The endoscope has traditionally been used in neurosurgery to access a lesion within a natural body cavity. The challenge has been to access and resect deep-seated intraparenchymal lesions using a minimally invasive endoscopic technique. Endoscopic endonasal trans-sphenoidal surgery has gained increasing acceptance by otolaryngologists and neurosurgeons. Surgical procedures of the skull base include exposure, resection, and base reconstruction. These approaches start at the sphenoid sinus, which provides a reference point to important vascular and neural structures...

Closed sinus lifting is a unique technique in being simple and less invasive (Summers, Compendium 15(6):698, 1994). However, it is blind to assess the safety of sinus lining during lifting without perforation. Previously, sinus membrane was assessed endoscopically in an invasive way. We aimed to judge clinically the sinus membrane integrity after crestal elevation by a direct simple less invasive endoscopic visual assessment through the crestal osteotomy site. To confirm undetected perforation, the sinus membrane was monitored dynamically by introducing the endoscope through a trephined opening in the lateral wall of the sinus (Nkenke et al...

Although the prevalence of gastroesophageal reflux disease (GERD) used to be lower in East Asia as compared to Western countries, it has recently been increasing, most likely due to the socioeconomic development in the East. The prevalence of both GERD and functional gastrointestinal disorders (FGIDs) ranges between 10% and 25% worldwide and there are distinct subgroups of patients with overlapping of GERD and FGIDs. However, the true prevalence of an overlap between GERD and FGIDs can be determined only when a formal pathophysiological evaluation has been performed...

Background  Surgical removal of parapharyngeal space tumors (PPST) poses challenges due to the complex anatomy of the region. PPSTs are routinely resected by a transcervical approach using blind finger dissection. Large PPSTs or those located high at the skull base, often require transmandibular or infratemporal fossa approaches, associated with considerable morbidity. Objective  Here, we describe an approach for PPST removal that comprises transcervical endoscopic, with or without transoral robotic technique...
