Background and study aim Single-tunnel endoscopic submucosal tunnel dissection (ESTD) has shown promising preliminary efficacy for large superficial esophageal squamous cell neoplasms (SESCNs). This study reports the outcomes of both single- and double-tunnel ESTD for large SESCNs, and compares the efficiency of the two techniques for treating circumferential SESCNs. Patients and methods 46 patients with large SESCNs underwent ESTD at a single hospital between October 2011 and March 2016. Relevant clinical data were retrospectively collected and analyzed...

NEC is an idiopathic intestinal mucosal injury that may progress to transmural bowel necrosis without mesenteric ischemia. NEC usually affects 7- to 10-day-old neonates following enteral feeding. A 10-month-old girl with no history of laparotomy underwent LDLT for acute liver failure. After starting enteral feeding on postoperative day 5, she developed abdominal distention. Diffuse PVG and PI were detected by radiologic modalities. Exploratory laparotomy revealed patchy necrosis of the intestine without perforation...

OBJECTIVES: Colorectal endoscopic submucosal dissection (ESD) shows higher R0 resection and lower local recurrence rates than endoscopic mucosal resection (EMR) in Japan. In Europe, independent learning of ESD in colorectum is feasible, but yet to be analyzed for curative resection and recurrence rates. METHODS: After experimental training under supervision by Japanese experts (T.O., N.Y.), three endoscopists independently performed 83 ESD procedures intention-to-treat for lesions in the entire colorectum of 67 patients in a prospective registry (Nov...

BACKGROUND: Familial adenomatous polyposis (FAP) is a rare, autosomal dominant disease clinically characterized by the early onset of many adenomatous polyps throughout the colon, which turn into colon cancer, if left untreated. In FAP patients, polyps can also occur in the upper gastrointestinal (GI) tract, especially in the duodenum. Adenomas beyond duodenum are rare and mostly located in the proximal jejunum and distal ileum. The management of such polyps can be either surgical or endoscopic, depending on the features of the polyp, Spigelman stage and patient's clinical conditions...

The current standard of treating early Barrett's neoplasia is resection of visible lesions using endoscopic mucosal resection (EMR) followed by ablative therapy to the Barrett's segment. There is increasing evidence to support the use of endoscopic submucosal dissection (ESD) where en-bloc resection and lower recurrence rates may be achieved. However, ESD is associated with deep submucosal dissection when compared to EMR. This may increase the risk of complications including stricture formation with subsequent radiofrequency ablation (RFA) therapy...

OBJECTIVE: Endoscopic submucosal dissection (ESD) aims to achieve en bloc resection of non-pedunculated colorectal adenomas which might be indicated in cases with superficial submucosal invasive cancers (SMIC), but the procedure is time consuming and complex. The prevalence of such cancers is not known but may determine the clinical necessity for ESD as opposed to the commonly used piecemeal mucosal resection (endoscopic mucosal resection) of colorectal adenomas. The main aim was to assess the prevalence of SMIC SM1 (ie, invasion ≤1000 µm or less than one-third of the submucosa) on colorectal lesions removed by ESD...

The incidence of rectal neuroendocrine tumors (NETs) has increased by almost ten-fold over the past 30 years. There has been a heightened awareness of the malignant potential of rectal NETs. Fortunately, many rectal NETs are discovered at earlier stages due to colon cancer screening programs. Endoscopic ultrasound is useful in assessing both residual tumor burden after retrospective diagnosis and tumor characteristics to help guide subsequent management. Current guidelines suggest endoscopic resection of rectal NETs ≤10 mm as a safe therapeutic option given their low risk of metastasis...

BACKGROUND: Transanal endoscopic microsurgery (TEMS) is a proven alternative therapy to either radical surgery or endoscopic mucosal resection for rectal neoplasms. It has proven benefits with lower morbidity and mortality compared with total mesorectal excision, and a lower local recurrence rate when compared to endoscopic mucosal techniques. METHODS: A retrospective data collection of TEMS procedures performed through Waikato District Health Board, New Zealand, from 2010 to 2015 was conducted...

A 10-week-old spayed female German Shepherd Dog was presented for acute vomiting and diarrhea. There was no reported foreign body or toxin ingestion. Radiographs showed a severely (∼11 × 7 cm), focally distended right abdominal intestinal segment containing gas and soft tissue material. Other small intestinal segments were segmentally gas distended. Celiotomy identified a ∼9 cm focally dilated segment at the jejunoileal junction with no aborad luminal obstruction. Resection and anastomosis of the dilation was performed...

Xanthogranulomatous cholecystitis (XGC) is an uncommon variant of chronic cholecystitis, characterized by focal or diffuse destructive inflammatory process. The importance of XGC is that it mimics gallbladder carcinoma (GBC) both preoperatively and intra-operatively, since it can present with pericholecystic infiltration, hepatic involvement and lymphadenopathy. As a result of this misdiagnosis which is not infrequent, the patient may need to undergo an unnecessary radical cholecystectomy rather than only a cholecystectomy which is associated with greater morbidity and mortality...

Background and study aims:  Endoscopic submucosal dissection (ESD) is useful for en bloc resection of superficial colorectal neoplasms to ensure accurate histologic diagnoses. However, colorectal ESD is associated with a high frequency of adverse events (AEs). We aimed to investigate the effectiveness of prophylactic clip closure (PCC) of mucosal defects for AEs after colorectal ESD. Patients and methods:  This study included 197 patients with 211 lesions who underwent colorectal ESD between June 2010 and August 2016...

The management of duodenal and colorectal tumours is important in patients with familial adenomatous polyposis (FAP). Endoscopic resection (ER) should be carefully performed because the risk of complications during or after (ER) of nonampullary duodenal tumours is higher than that of stomach or colorectal lesions in general. Thus, we evaluated the feasibility of endoscopic resection using bipolar snare (ERB) for nonampullary duodenal tumours in FAP patients. Eleven FAP patients who underwent ERB for nonampullary duodenal tumours at our hospital between October 2013 and December 2016 were retrospectively analysed based on clinicopathological features...

BACKGROUND: Endoscopic submucosal dissection (ESD) enables the complete removal of gastric lesions regardless of tumor size. ESD is typically performed using one of several available electrocautery knives and endoscopic mucosal resection (EMR) is performed using a diathermic snare. We aimed to investigate the clinical outcomes and complications in patients in whom a snare tip was used for ESD. MATERIALS AND METHODS: We retrospectively evaluated the medical records of 30 patients who underwent removal of a gastric lesion using a snare tip by ESD or hybrid ESD (ESD with snaring)...

Gastrointestinal (GI) schwannoma is one of the rarest tumors of the GI tract. We herein describe the case of a 70-year-old female patient who presented for surveillance colonoscopy. The examination detected a 1-cm polyp that was removed by snare cautery polypectomy. Immune and histochemical staining revealed spindle cells that were positive for S-100 and vimentin, but negative for CD34 and smooth muscle actin, consistent with GI schwannoma. This case is noteworthy as GI schwannomas usually present in the stomach, making the finding of a colonic schwannoma of clinical interest...

Background and study aims Many studies have reported on laterally spreading tumors (LSTs), but systematic reviews of the data to determine their risk of containing submucosal invasion (SMI) are lacking. We systematically screened and analyzed the available literature to provide a more solid basis for evidence-based treatment. Methods We conducted a systematic search in PubMed, Embase, the Cochrane Library, and Scopus for published articles until July 2017. We estimated pooled prevalence or odds ratios (ORs) with 95 % confidence intervals (CIs), using random-effects models...

PURPOSE: The main limitation of surgical treatment of medication-related osteonecrosis of the jaw (MRONJ) is difficulty in defining resection margins. The aim of this study was to compare the efficacy of the surgeon's experience and autofluorescence-guided bone surgery to delimit resection margins for necrotic bone. MATERIALS AND METHODS: MRONJ requiring surgical treatment was classified according to American Association of Oral and Maxillofacial Surgeons staging...

The bladder urothelium functions as a urine-blood barrier and consists of basal, intermediate, and superficial cell populations. Reconstructive procedures such as augmentation cystoplasty and focal mucosal resection involve localized surgical damage to the bladder wall whereby focal segments of the urothelium and underlying submucosa are respectively removed or replaced and regeneration ensues. We demonstrate using lineage-tracing systems that urothelial regeneration following augmentation cystoplasty with acellular grafts exclusively depends on host keratin 5-expressing basal cells to repopulate all lineages of the de novo urothelium at implant sites...

Background and study aims Large series suggest endoscopic mucosal resection is safe and effective for the removal of large (≥ 10 mm) sessile serrated polyps (SSPs), but it exposes the patient to the risks of electrocautery, including delayed bleeding. We examined the feasibility and safety of piecemeal cold snare polypectomy (pCSP) for the resection of large SSPs. Methods Sequential large SSPs (10 - 35 mm) without endoscopic evidence of dysplasia referred over 12 months to a tertiary endoscopy center were considered for pCSP...
