INTRODUCTION: Since Kambin introduced the concept of percutaneous transforaminal disc surgery in 1973, there has been numerous advances in the field of spine endoscopy and the concept of central debulking of the disc has changed to targeted fragmentectomy and disc preservation. The lumbar disc fragments which are down migrated and to the medial aspect of the pedicle are extremely challenging to deal by transforaminal approach even after foraminoplasties and by various other approaches...

Advanced therapeutic endoscopy, in particular endoscopic mucosal resection, endoscopic submucosal dissection, per-oral endoscopic myotomy, submucosal endoscopic tumor resection opened a new era where direct esophageal visualization is possible. Combining these information with advanced diagnostic endoscopy, the esophagus is organized, from the luminal side to outside, into five layers (epithelium, lamina propria with lamina muscularis mucosa, submucosa, muscle layer, adventitia). A specific vascular system belonging to each layer is thus visible: Mucosa with the intra papillary capillary loop in the epithelium and the sub-epithelial capillary network in the lamina propria and, at the lower esophageal sphincter (LES) level with the palisade vessels; submucosa with the drainage vessels and the spindle veins at LES level; muscle layer with the perforating vessels; peri-esophageal veins in adventitia...

INTRODUCTION: High-grade vesicoureteral reflux (VUR) in infants is associated with congenital renal abnormalities, recurrent UTI, and bladder dysfunction. Endoscopic treatment (ET) is a well-established method in children with low to moderate reflux grades, but there is a lack of randomised controlled trials regarding the use of ET versus continuous antibiotic prophylaxis in infants with high-grade VUR. OBJECTIVE: This study aimed to determine whether high-grade VUR in infants can be treated with endoscopic injection and whether ET is superior to antibiotic prophylaxis in the treatment of VUR...

BACKGROUND: Non-anesthesia administered propofol (NAAP) has been shown to be a safe and effective method of sedation for patients undergoing gastrointestinal endoscopy. Bariatric surgery patients are potentially at a higher risk for sedation-related complications due to co-morbidities including obstructive sleep apnea. The outcomes of NAAP in bariatric patients have not been previously reported. METHODS: In this retrospective cohort study, severely obese patients undergoing pre-surgical outpatient esophagogastroduodenoscopy (EGD) were compared to non-obese control patients (BMI ≤ 25 kg/m(2)) undergoing diagnostic EGD at our institution from March 2011-September 2015 using our endoscopy database...

BACKGROUND AND AIMS: Recent advances in endoscopic equipment and diagnostic techniques have made possible the detection of early dysplasia in the inflamed mucosa of ulcerative colitis (UC). The SCENIC consensus statement recommends the use of unified terminology for the morphology of dysplasia. In this study, we investigated the endoscopic features of high-grade dysplasia (HGD) in a clinical setting. METHODS: We retrospectively identified 62 patients with UC who were diagnosed with colitis-associated cancer or HGD between 1997 and 2015...

BACKGROUND: Endoscopic ultrasound (EUS) has been routinely utilized for the locoregional staging of esophageal cancer. One important aspect of clinical staging has been to stratify patients to treatment with neoadjuvant chemoradiation or primary surgical therapy. We hypothesized that EUS may have a limited impact on clinical decision making in patients with dysphagia and obstructing esophageal masses. METHODS: This retrospective cohort study included all patients with esophageal adenocarcinoma undergoing esophageal EUS between July 2008 and September 2013...

Recent advances in submucosal endoscopy have unlocked a new horizon for potential development in diagnostic and therapeutic endoscopy. Increasing evidence has demonstrated that peroral endoscopic myotomy (POEM) is not only clinically feasible and safe, but also has excellent results in symptomatic relief of achalasia. The success of submucosal endoscopy in performance of tumor resection has confirmed the potential of this new area in diagnostic and therapeutic endoscopy. This article reviews the current applications and evidence, from POEM to peroral endoscopic tunnel resection (POET), while exploring the possible future clinical applications in this field...

Incidence of oesophageal adenocarcinoma has increased exponentially in the West over the past few decades. Following detection of advanced cancers, 5-year survival rates remain bleak, making identification of early neoplasia, which has a better outcome, important. Detection of subtle oesophageal lesions during endoscopy can be challenging, and advanced imaging techniques might improve their detection. High-definition endoscopy has become a standard in most endoscopy centres, and this technology probably provides better delineation of mucosal features than standard-definition endoscopy...

BACKGROUND: Gastric outlet obstruction (GOO) can occur with locally invasive or metastatic cancer involving the upper gastrointestinal tract at the pylorus or the duodenum. Endoscopic management with self-expanding metal stents (SEMSs) is often the preferred palliative approach. Stent occlusion is a common reason for failure and reintervention. We set out to determine whether the location of the malignant obstruction is associated with the angulation of the stent and can predict stent occlusion...

BACKGROUND: Gastric cancer (GC) is the fifth most common cancer worldwide. Since development is usually asymptomatic, it is generally diagnosed at an advanced stage. The value of screening in patients with nonspecific symptoms for GC is controversial. AIM: The study aimed to evaluate whether hematological parameters (platelet count (PC), mean platelet volume (MPV), MPV/PC ratio, red blood cell distribution width (RDW), neutrophil to lymphocyte ratio (NLR), and platelet to lymphocyte ratio (PLR)) are useful markers to differentiate between gastric cancer patients and healthy individuals...

The stomach may be involved by a myriad of pathologies ranging from benign etiologies like inflammation to malignant etiologies like carcinoma or lymphoma. Multidetector computed tomography (MDCT) of the stomach is the first-line imaging for patients with suspected gastric pathologies. Conventionally, CT imaging had the advantage of simultaneous detection of the mural and extramural disease extent, but advances in MDCT have allowed mucosal assessment by virtual endoscopy. Also better three-dimensional (3D) post-processing techniques have enabled more robust and accurate pre-operative planning in patients undergoing gastrectomy and even predict the response to surgery for patients undergoing laparoscopic sleeve gastrectomy for weight-loss...
