(i) Following piecemeal resection and en bloc resection for LST ≥ 40 mm, hospitalize patients for 36 h and note risk for incomplete resection and delayed bleeding. (ii) After en bloc resection for 40 mm > LST ≥ 30 mm, hospitalize patients for 12 h and note risk for incomplete resection. (iii) Following en bloc resection for LST < 30 mm, hospitalize the patient for 12 h and expect complete resection.

Curative resection rate of ESD in patients with clinical epithelial or lamina propria mucosal cancers was not low at 70%. However, the risk of stricture must be taken into account when considering the use of ESD in lesions ≥50 mm.

The pathology showed gastric mucosa and squamous epithelium and focal intestinal metaplasia. This finding could be a clue as to the origins of the heterotopic gastric mucosa. Although there are no guidelines for treatment or the follow‐up period, regular endoscopic surveillance is necessary for gastric cancer screening.

She visited a dermatology clinic with a complaint of discomfort in the anal region. Erosion was observed in the anal region, and biopsies were performed. She was diagnosed with Bowen's disease and was referred to the dermatology department of our hospital for treatment. At our department, an endoscopic examination was performed for assessing the extent of Bowen's disease in the rectum. A retroflexed view of the anal canal revealed a slightly raised lesion with a faded color and an irregular surface. Narrow‐band imaging (NBI) revealed a whitish lesion with a relatively clear margin and brown dots on the inside. Magnifying endoscopy with NBI revealed abnormal microvessels with dilatation, tortuosity, caliber change and various shapes, which were qui...

A 74‐year‐old man had an advanced rectal cancer and gastrointestinal polyposis after presenting with hypoproteinemia, partial hair loss and atrophic nails as well as hyperpigmentation on the hands. He was diagnosed as having CCS. On upper endoscopy, a 7 mm discolored polyp with an irregular microvascular pattern revealed by magnified narrow‐band imaging (NBI) was identified in gastric diffuse CCS polyposis.

A 51‐year‐old female patient was scheduled for elective LRYGBP. Her weight was 144.9 kg and her body mass index was 56. Liver function tests showed mild elevation in alanine transaminase. The patient had a history of hypertension and insulin resistance and had no history of alcohol abuse. During LRYGBP, the gross appearance of the liver resembled metastatic lesions but the histology confirmed the diagnosis of non‐alcoholic steatohepatitis. The appearance of the liver necessitated taking biopsies, which showed Von Meyenburg complexes and moderate macrovesicular steatosis. This patient made an uneventful recovery and was discharged 2 days postoperat...

A systematic review of the literature was undertaken to analyze clinical trials on GOO. Six studies were eligible for analysis (three randomized control trials and three controlled clinical trials). Technical success (OR [95% CI]: 0.10 [0.02, 0.47]; I2 = 0%; P = 0.003) and minor complications (OR [95% CI]: 0.28 [0.10, 0.83]; I2 = 49%; P = 0.02). Time to oral intake and length of survival were also shorter in the endoscopic stenting (ES) group.

Furthermore, looping formation may prevent a complete colonoscopy from being carried out in certain patients. The conventional colonoscope has not changed very much since its original introduction. We review promising technologies that are being promoted as a way to address the problems with current colonoscopy. There are some methods to prevent looping formation, including overtube, variable stiffness, computer‐guided scopes, Aer‐O‐Scope™, magnetic endoscopic imaging and the capsule endoscope.

The purpose of the preliminary meeting was to consider the areas that require attention, to discuss some of the findings that have already been published and to agree on the way forward. Our reason for publishing these proceedings is to stimulate interest in this venture and to provide the opportunity for input from the endoscopy community worldwide. The next meeting of the working party will be at the JGES Society meeting in Aomori in April 2011 when we hope to prepare a preliminary classification. This will be presented for general discussion and debate at the International Congress of Endoscopy (ICE) in Los Angeles in September 2011. (Sour...

Biopsy specimens from this lesion were suspicious of carcinoid tumor. We suspected this lesion to be a sporadic gastric carcinoid tumor with a diameter of 5 mm, limited to the mucosal layer. We then performed an endoscopic aspiration mucosectomy with a cap‐fitted endoscope. Microscopically, the lesion obtained from the resected specimen was minimally invasive to the submucosa and showed highly differentiated columnar cells in irregularly anastomosing glands. Immunohistology was positive for pepsinogen‐I, and MUC6, partially positive for H+/K+‐ATPase, and negative for MUC5AC. In addition, it was positive for s...

However, in general, surgically altered anatomy excluding Billroth I gastrectomy is considered a relative contraindication to EUS‐FNA. Herein, we described a successful case of EUS‐FNA in a patient with prior Billroth II gastrectomy. A 78‐year‐old man, who had previously undergone Billroth II gastrectomy for duodenal ulcer, undertook EUS‐FNA using a curved linear echoendoscope. An echoendoscope was advanced into the duodenum and EUS‐FNA could be carried out using a 22‐gauge needle without procedure‐related adverse event.

Recently, several endoscopists have reported the endoscopic ultrasound (EUS)‐guided liver abscess drainage. Herein, we report a case of tuberculous liver abscess in which endoscopic ultrasound‐guided fine needle aspiration (EUS‐FNA) was useful for the diagnosis and therapy. A 78‐year‐old woman suffered from continuous epigastric pain and fever up. Computed tomography (CT) showed a 70 mm multilocular and multiseptate cystic lesion around the head of pancreas and caudate lobe of the liver. After confirming liver abscess by EUS‐FNA, EUS‐guided liver abscess drainage was carried out. Finally, a 7 Fr straight stent and a 5 Fr nasocystic catheter were inserted into the cyst.

Although ultra‐slim pediatric or Tran nasal video endoscopes are usually used for the direct peroral video cholangioscopy, direct scope insertion without pretreatment and any assistant is considerably difficult. Based on the previous literatures, intraductal balloon catheter‐assisted scope insertion might be relatively reliable method. To overcome the issue on the scope insertion, recently prototype cholangioscope that has short bending section and anchoring balloon catheter for scope replacement and insertion has been developed. In the near future, we could establish the direct peroral cholangioscopy using new developed technology. (Sou...

It has evolved over the past 30 years. The gastrointestinal endoscopy unit at the University of Malaya Medical Centre has been in the forefront in providing endoscopy services to patients as well as training doctors in endoscopy in the country. In recent years, trainees have included those from neighboring countries in South‐East Asia. Among our most significant achievements is the organization of regular international therapeutic endoscopy workshops since 1993 where leading endoscopists from throughout the world have accepted our invitation as teaching faculty.

It is thus suggested that NBI can be used for the assessment of severity in inflammatory bowel diseases, especially in ulcerative colitis (UC). In the active UC, NBI colonoscopy depicts friability as a black area. In the inflamed granular mucosa, crypt openings and villous structure become evident through the procedure. In the inactive UC, there are two types of mucosal vascular pattern; one being composed of deep, green vessels and superficial, black vessels, and the other lacking in superficial vessels.

Consequently, loss of this network could correlate with depth of tumor invasion and histological reaction. Therefore, even if the tumor, remained of network was diagnosed to invade into SM layer, it should be checked up further examination by using magnifying endoscopy with crystal violet staining.

Their broad findings have been divided into six groups according to endoscopical vascular features: normal, faint, network, dense, irregular and sparse. Most hyperplastic polyps show a faint pattern. The vascular patterns of adenomas are mainly network or dense ones. The predominant vascular patterns of cancer were irregular and sparse. Indeed, irregular pattern has found to be characteristic for protruded or flat‐elevated cancer, whereas sparse pattern unique for depressed cancer. Through NBI, neoplastic lesions could be differentiated from those non‐neoplastic with sensitivity of 83.5%, specificity of 98.7% and accuracy of 98.2%.

EUS provides images with a high resolution such that the depth of tumor invasion can be accurately determined. It also sees lesions outside of gastrointestinal tract, particularly those in pancreas, biliary system and periluminal lymph nodes. The most important limitation of EUS was lack of specificity, that is, the differentiation between benign and malignant lesions.

Number of EUS procedures conducted annually for pancreatic malignancies. 2. Role of radial arrayed EUS for pancreatic abnormalities. 3. Role of curved‐linear arrayed EUS for pancreatic abnormalities. 4. Indication of EUS‐guided fine‐needle aspiration biopsy (EUS‐FNA) for pancreatic abnormalities. 5. Percentage of EUS‐FNA among the cases carried out with EUS for pancreatic abnormalities. 6. Experience of EUS with contrast harmonic echo for pancreatic malignancies and its indications. 7. Experience of elastography on EUS for pancreatic abnormalities. In Japan, although usage ...

Currently, there are two types of EUS available for use: radial and convex arrayed EUS. Each type of EUS has its own advantages and disadvantages. Because radial arrayed EUS can obtain 360 degree images, it is easy to see surrounding organs and vessels. In addition, a single longitudinal image of the pancreas, gallbladder and bile duct is easy to obtain. For this reason, radial arrayed EUS is highly effective in diagnostic examinations. In contrast, while scanning range of convex arrayed EUS limited to 180 degrees, it has the advantage of being able to obtain tissue samples. Additionall...

In these cases, endoscopic resection (ER) and surveillance was carried out without additional surgical resection. Local recurrence or metastasis was observed in 18 cases. Local submucosal recurrence was observed in 11 cases, and metastatic recurrence was observed in 13 cases. Among the 15 cases in which the depth of submucosal invasion was measured, two cases showed depth less than 1000 µm, which has other risk factors for metastasis. Metastatic recurrence was observed in the lung, liver, lymph node, bone, adrenal ...

Gastric tubular adenoma (flat adenoma) is common and focal cancers occurring in the hyperplastic polyp of foveolar cell type are also sometimes experienced. However, adenomas occurring in sporadic FGP are valuable, as they are very rare, in upper gastrointestinal endoscopy. Whether or not these adenoma lesions of three sporadic FGP cases may become the background of protruded gastric cancers without HP infection remains unclear. Therefore, we emphasize the importance of histological examination on fundic gland polyps that are >5 mm in size to ...

However, because this complication adversely affects patients' prognoses, it is important to check for the presence of AMY, particularly in the duodenum, in patients for whom more than 10 years have elapsed since the development of CD.

Ethanol should be injected on both sides of the celiac axis to obtain greater pain relief.

Animal survival studies are needed to explore technical and wound‐closure‐related problems arising as a result of use of endoclips and endoloops for gastrotomy closure.
