Background/Aims: Chronic liquid and/or food stasis caused by retention esophagitis (RE) in achalasia is a notable endoscopic finding because of the presence of a thickened or whitish esophageal mucosa and histologically altered squamous hyperplasia. We aimed to identify the clinical features of RE associated with achalasia and to clarify the clinical definition of RE in achalasia as a precancerous lesion identified by analyzing biomarker expressions. Methods: From 2006 to 2015, we retrospectively reviewed 37 patients with achalasia without previous treatment...

We report our experience with a case of stomach perforation after accidental ingestion of liquid nitrogen. A 13-year-old boy ate a snack at an amusement park and began to complain of sudden onset of severe abdominal pain with shortness of breath. It was determined that the snack he had ingested had been cooled with liquid nitrogen. A computed tomography scan of the abdomen and a chest X-ray showed a large volume of pneumoperitoneum. During surgery, a 4-cm perforation of the angularis incisura of the stomach was identified...

Ectopic sebaceous glands are found very rarely in the esophagus; heretofore, several cases have been reported. The sebaceous gland is originally a source of an endodermal origin; however, there have been controversies regarding whether the origin of the esophageal ectopic sebaceous gland is ectodermal or endodermal. Ectopic sebaceous glands of the esophagus usually do not cause symptoms; thus, they are often found incidentally on endoscopy for routine health screening. Endoscopic findings are characterized by single or multiple yellow patches or nodular lesions of various sizes, sometimes with small central openings...

The concept of using natural orifices to reduce the complications of surgery, Natural Orifices Transluminal Endoscopic Surgery, has also been applied to therapeutic endoscopy. Endoscopic submucosal surgery (ESS) provides more treatment options for various gastrointestinal diseases than traditional therapeutic endoscopy by using the submucosal layer as a working space. ESS has been performed in various fields ranging from transluminal peritoneoscopy to peroral endoscopic myotomy. With further advances in technology, ESS will be increasingly useful for diagnosis and treatment of gastrointestinal diseases...

Endoscopic full-thickness resection combined with laparoscopic surgery was recently developed. These procedures could be categorized as "Cut first and then suture" and "Suture first and then cut". "Cut first and then suture" includes laparoscopic and endoscopic cooperative surgery (LECS) and laparoscopy-assisted endoscopic full-thickness resection (LAEFR). Recent studies have demonstrated the safety and efficacy of LECS and LAEFR. However, these techniques are limited by the related exposure of the tumor and gastric mucosa to the peritoneal cavity and manipulation of these organs, which could lead to viable cancer cell seeding and the spillage of gastric juice into the peritoneal cavity...

Background/Aims: To present a single center's experience with percutaneous endoscopic gastrostomy (PEG) tube placement in infants. Methods: Clinical records of infants who underwent PEG tube placement between January 2010 and December 2015 were reviewed. All patients underwent an upper gastrointestinal contrast study and an abdominal ultrasonography before the procedure. PEGs were performed with a 6-mm endoscope using the standard pull-through technique. Data regarding gestational age, birth weight, age and weight, days to feeding start, days to full diet, and complications were reviewed...

Background/Aims: Direct endoscopic pancreatic necrosectomy is increasingly being utilized to treat infected or symptomatic walled-off necrosis (WON) located close to the stomach or duodenum. Laterally-placed WON has traditionally been treated surgically. We evaluated a less utilized technique of sinus tract endoscopy (STE) for symptomatic laterally-placed WON. Methods: Two hundred seventy-six patients with acute pancreatitis admitted in our hospital, 32 had symptomatic or infected WON requiring intervention...

Background/Aims: The aim of this study was to investigate the use of non-exposure endoscopic wall-inversion surgery (NEWS) and the combination of laparoscopic and endoscopic approaches to neoplasia with non-exposure technique (CLEAN-NET) in gastric tumors. Methods: We reviewed all cases of NEWS and CLEAN-NET performed in the department of surgery of the Royal Vinohrady Teaching Hospital. Results: Our department performed 12 gastric tumor resections (NEWS, n=10 and CLEAN-NET, n=2) between March 2016 and February 2017...

Peroral endoscopic myotomy (POEM) has been established as an optional treatment for achalasia. POEM is an endoluminal procedure that involves dissection of esophageal muscle fibers followed by submucosal tunneling. Inoue first attempted to use POEM for the treatment of achalasia in humans. Expanded indications of POEM include classic indications such as type I, type II, type III achalasia, failed prior treatments, including Botulinum toxin injection, endoscopic balloon dilation, laparoscopic Heller myotomy, and hypertensive motor disorders such as diffuse esophageal spasm, jackhammer esophagus...

Colorectal cancer (CRC) is the third most common cancer worldwide. It is amenable to screening as it occurs in premalignant, latent, early, and curable stages. PubMed, Cochrane Database of Systematic Reviews, and national and international CRC screening guidelines were searched for CRC screening methods, populations, and timing. CRC screening can use direct or indirect tests, delivered opportunistically or via organized programs. Most CRCs are diagnosed after 60 years of age; most screening programs apply to individuals 50-75 years of age...

The full-thickness resection device (FTRD) is a novel endoscopic device approved for the resection of colorectal lesions. This case-series describes the device and its use in high-risk patients with colorectal lesions and provides an overview of the potential indications in recently published data. Between December 2014 and September 2015, 3 patients underwent endoscopic full thickness resection using the FTRD for colorectal lesions: 1 case for a T1 adenocarcinoma in the region of a surgical anastomosis after recto-sigmoidectomy, 1 case for a non-lifting colonic adenoma with low-grade dysplasia in an 89-year old patient and 1 for a recurrent adenoma with high-grade dysplasia in a young patient with ulcerative rectocolitis who was under immunosuppression after renal transplantation...

Gastrointestinal subepithelial tumors (SETs) are generally found during endoscopy and their incidence has gradually increased. Although the indications for the endoscopic treatment of patients with SETs remain to be established, the feasibility and safety of endoscopic dissection, including the advantages of this method compared with surgical treatment, have been validated in many studies. The development of endoscopic techniques, such as endoscopic submucosal dissection, endoscopic enucleation, endoscopic excavation, endoscopic submucosal tunnel dissection, submucosal tunnel endoscopic resection, and endoscopic full-thickness resection has enabled the removal of SETs while reducing the occurrence of complications...

Colonoscopy is currently regarded as the gold standard and preferred method of screening for colorectal cancer (CRC). However, the benefit of colonoscopy screening may be blunted by low participation rates in population-based screening programs. Harmful effects of population-based colonoscopy screening may include complications induced by colonoscopy itself and by sedation, psychosocial distress, potential over-diagnosis, and socioeconomic burden. In addition, harmful effects of colonoscopy may increase with age and comorbidities...

Gastroparesis (GP) is a syndrome characterized by delayed gastric emptying in the absence of mechanical obstruction of the stomach or proximal small bowel. Currently available dietary and medical therapies are limited and have suboptimal efficacy. Pylorus-directed therapies have showed promising results. Gastric peroral endoscopic myotomy (G-POEM) has been reported for the treatment of GP refractory to standard therapy with promising results. This article reviews the current applications and results of G-POEM for the treatment of refractory GP...
