Bronchogenic cysts are rare foregut abnormalities that arise from aberrant budding of the tracheobronchial tree early in embryological development. They account for 10% to 15% of all primary masses of the mediastinum (1), where they appear predominantly and may compress nearby structures. Intra-esophageal bronchogenic cysts are rare and have only been reported in 23 adult cases since 1981 (2). We report an intra-esophageal bronchogenic cyst that was removed by endoscopic mucosal dissection (ESD). This article is protected by copyright...

Abnormal thickened lesions of the gastric wall are usually covered with normal mucosa. Conventional endoscopic biopsies often do not yield sufficient positive histological results for clinical treatment. To increase the rate of diagnosis of conventional endoscopic biopsy-negative gastric wall thickening, we used an endoscopic submucosal dissection (ESD)-like sampling method under endoscopic ultrasound (EUS) guidance to obtain tissue of gastric wall-thickening lesions. Between 2012 and 2016, patients with gastric wall thickening (as identified by computed tomography (CT), EUS or other imaging methods that showed no positive findings in repeating conventional endoscopic biopsy) underwent via mucosa incision EUS-guided sampling...

BACKGROUND AND AIMS: Due to previous manipulation or submucosal invasion, GI lesions referred for endoscopic mucosal resection (EMR) frequently have flat areas of visible tissue that cannot be snared. Current methods for treating residual tissue may lead to incomplete eradication or not allow complete tissue sampling for histologic evaluation. Our aim is to describe dissection-enabled scaffold-assisted resection (DeSCAR), a new technique combining circumferential ESD with EMR for removal of superficial non-lifting or residual "islands" with suspected submucosal involvement/fibrosis...

Gastrointestinal submucosal tumors (SMTs) have been increasingly identified via the use of endoscopic ultrasonography, and removal is often recommended for SMTs that are >2 cm in diameter or symptomatic. Submucosal tunneling endoscopic resection (STER), also known as submucosal endoscopic tumor resection, endoscopic submucosal tunnel dissection or tunneling endoscopic muscularis dissection, is a novel endoscopic technique for treating gastrointestinal SMTs originating from the muscularis propria layer, and has been demonstrated to be effective in the removal of SMTs with a decreased rate of recurrence by clinical studies...

Boerhaave syndrome, the spontaneous perforation of the esophagus, is an emergency, life-threatening condition. Current endoscopic treatment options include clipping and stenting, but the use of polyglycolic acid (PGA) sheets for treating the condition has not been reported. In recent years, PGA sheets have been used after endoscopic submucosal dissection to prevent perforations and stricture formation in patients treated for early-stage carcinoma. We report the cases of two patients with Boerhaave syndrome who were successfully treated using PGA sheets...

OBJECTIVE: The aim of this study was to evaluate the outcomes of endoscopic submucosal dissection (ESD) for superficial proximal esophageal neoplasia. SUMMARY OF BACKGROUND DATA: The surgery for a tumor located in proximal esophagus is relatively difficult and leads to a high morbidity and mortality. ESD is a minimally invasive endoscopic treatment of superficial neoplasia of the gastrointestinal tract allowing en block resection with low recurrence rates; however, ESD for superficial proximal esophageal neoplasia is little known...

BACKGROUND: Being grade 2 is a known risk factor for metastasis in rectal neuroendocrine tumors (R-NETs). We aimed to identify the efficacy of the Ki-67 labeling index (LI) in endoscopic biopsy specimens to predict the World Health Organization (WHO) grade of R-NETs. METHODS: A total of 59 patients with 60 R-NETs (43 WHO grade 1 and 17 WHO grade 2), treated between October 2002 and December 2014, were retrospectively evaluated. The patients included in the study underwent biopsies followed by endoscopic submucosal resection with a ligation device, trans-anal full-thickness surgical resection, or radical surgery with lymph node dissection...

Esophageal cancer is the 8th most common cancer worldwide and the 6th most common cause of cancer-related death. Its two main subtypes, esophageal adenocarcinoma (EAC) and esophageal squamous cell carcinoma (ESCC), have varying incidences globally, but recent decades have seen a demonstrated rise of EAC in Western countries whereas ESCC remains highly prevalent in Eastern Africa, Central Asia, and China. Screening interventions have focused on using endoscopy to identify Barrett's esophagus (BE) as a precursor to EAC, and squamous cell dysplasia prior to onset of ESCC...

Endoscopic submucosal dissection (ESD) using a scissors-type knife, the Stag-Beetle knife (SB knife, Sumitomo Bakelite, Tokyo, Japan), is considered technically easy and safe due to its ability to grasp the target tissue to allow controlled resection without the complex endoscopic tip control required with conventional ESD devices. There are two types of SB knife (short-type and Jr-type), used mainly for esophageal and colorectal neoplasms (1-3). Recently, a new type, SB knife GX, has been developed for gastric ESD...

Background and study aims  Endoscopic submucosal dissection (ESD) for duodenal tumors results in a high delayed perforation rate due to the thinness of the duodenal wall. In most cases with perforation after duodenal ESD, additional surgery is needed due to severe peritonitis. A newly developed procedure, laparoscopic endoscopic cooperative surgery for duodenal tumors (D-LECS), may help to avoid perforation after ESD. In our institution, patients with superficial non-ampullary duodenal epithelial tumors (SNADET) smaller than 50 mm which could not have en-bloc resection by endoscopic mucosal resection were treated with D-LECS...

BACKGROUND AND AIMS: Several reports have described the major adverse events after endoscopic submucosal dissection (ESD), such as perforation or bleeding. However, few studies have discussed the occurrence of post-ESD electrocoagulation syndrome (PEECS) after colorectal ESD. Additionally, the occurrence of fever without abdominal pain in patients requires postoperative management similar to that required for PEECS. Therefore, we have defined post-ESD inflammatory syndrome (PEIS) as composed of both PEECS and fever without abdominal pain...

REVIEW
Benjamin Meier, Karel Caca, Andreas Fischer, Arthur Schmidt
Colorectal adenomas are well known precursors of invasive adenocarcinoma. Colonoscopy is the gold standard for adenoma detection. Colonoscopy is far more than a diagnostic tool, as it allows effective treatment of colorectal adenomas. Endoscopic resection of colorectal adenomas has been shown to reduce the incidence and mortality of colorectal cancer. Difficult resection techniques are available, such as endoscopic mucosal resection, endoscopic submucosal dissection and endoscopic full-thickness resection. This review aims to provide an overview of the different endoscopic resection techniques and their indications, and summarizes the current recommendations in the recently published guideline of the European Society of Gastrointestinal Endoscopy...
