Compared with endoscopic submucosal dissection (ESD), endoscopic mucosal resection (EMR) is easier to perform and requires less time for treatment. However, EMR has been replaced by ESD, because achieving en bloc resection of specimens > 20 mm in diameter is difficult with EMR. The technique of ESD was introduced to resect large specimens of early gastric cancer in a single piece. ESD can provide precise histological diagnosis and can also reduce the rate of recurrence, but has a high level of technical difficulty, and is consequently associated with a high rate of complications, a need for advanced endoscopic techniques, and a lengthy procedure time. To overcome disadvantages in both EMR and ESD, various advances have been made in submucosal injections, knives, other accessories, and in electrocoagulation systems.  相似文献

Interventional procedures using endoscopic ultrasound (EUS) have recently been developed. For biliary drainage, EUS-guided trans-luminal drainage has been reported. In this procedure, the transduodenal approach for extrahepatic bile ducts is called EUS-guided choledochoduodenostomy, and the transgastric approach for intrahepatic bile ducts is called EUS-guided hepaticogastrostomy (EUS-HGS). These procedures have several effects, such as internal drainage and avoiding post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis, and they are indicated for an inaccessible ampulla of Vater due to duodenal obstruction or surgical anatomy. EUS-HGS has particularly wide indications and clinical impact as an alternative biliary drainage method. In this procedure, it is necessary to dilate the fistula, and several devices and approaches have been reported. Stent selection is also important. In previous reports, the overall technical success rate was 82% (221/270), the clinical success rate was 97% (218/225), and the overall adverse event rate for EUS-HGS was 23% (62/270). Adverse events of EUS-biliary drainage are still high compared with ERCP or PTCD. EUS-HGS should continue to be performed by experienced endoscopists who can use various strategies when adverse events occur.  相似文献

The well established, gold standard method for treatment of obstructive jaundice involves biliary drainage under endoscopic retrograde cholangiopancreatography(ERCP) performed by pancreatobiliary endoscopists. Recently, interventions using endoscopic ultrasound(EUS) have been developed not only for obtaining cytological and histological diagnosis, but also for biliary drainage as alternative method. EUS-guided biliary drainage(EUSBD) was first reported by Giovannini et al. EUS-BD broadly includes EUS-guided rendezvous technique, EUS-guided choledochoduodenostomy, and EUS-guided hepaticogastrostomy. More recently, EUS-guided antegrade stenting and EUS-guided gallbladder drainage have also been reported. many case reports, series, and retrospective studies on EUS-BD have been reported. However, because prospective studies and comparisons between the different biliary drainage methods have not been reported, the technical success, functional success, adverse events, and stent patency with long-term follow up of EUS-BD are still unclear. Therefore, prospective, randomized controlled studies addressing these issues are needed. Despite this, EUSBD undoubtedly is clinically useful as an alternative biliary drainage method. EUS-BD has the potential to be a first-line biliary drainage method instead of ERCP if results of clinical trials are favorable and the technique is simplified.  相似文献

Gastro-oesophageal reflux disease represents an extremely common disorder which has a substantial impact on patients' quality of life and use of health care resources. Gastro-oesophageal reflux disease is a chronic relapsing disease for which a lifelong solution is needed. Until now the two competing therapeutic modalities have been the medical and surgical therapies. Quite recently a third option has become available. A number of endoscopic anti-reflux procedures have been described, with the common goal of creating an anti-reflux barrier, thus obviating long-term proton pump inhibitors and the cost and potential risk of laparoscopic Nissen fundoplication. In this review the different techniques are thoroughly examined and the results are critically evaluated, giving special emphasis to efficacy, safety and durability of these new anti-reflux procedures. Available data show that these anti-reflux techniques produce significant improvement in gastro-oesophageal reflux disease symptomatology and quality of life as well as reduce the use of anti-reflux medication, without causing serious morbidity or mortality. However, the majority of these techniques have failed to adequately control oesophageal acid reflux. Endoscopic anti-reflux therapies therefore sound very attractive-being less invasive than surgery-and show a significant promise, but are still in the early stages of assessment. Large-scale randomized multi-centre trials comparing control groups with sham procedures are essential to confirm their efficacy. Further studies are also necessary to determine what modifications these techniques require in order to produce maximum clinical efficacy and durability. However, considering that current therapies (both medical and surgical) of gastro-oesophageal reflux disease are highly effective, the need for such new endoscopic modalities may be questionable. Moreover, appropriate trials in dedicated centres should be carried out to assure that the enthusiasm commonly associated with new technology is justified and can be generalized to open-access endoscopists.  相似文献

Most patients who require biliary drainage can be treated by endoscopic retrograde cholangiopancreatography (ERCP)-guided procedures. However, ERCP can be challenging in patients with complications, such as malignant duodenal obstruction, or a surgically-altered anatomy, such as a Roux-en-Y anastomosis, which prevent advancement of the duodenoscope into the ampulla of Vater. Recently, endoscopic ultrasound (EUS)-guided biliary drainage via transhepatic or transduodenal approaches has emerged as an alternative means of biliary drainage. Typically, EUS-guided gallbladder drainage or choledochoduodenostomy can be performed via both approaches, as can EUS-guided hepaticogastrostomy (HGS). EUS-HGS, because of its transgastric approach, can be performed in patients with malignant duodenal obstruction. Technical tips for EUS-HGS have reached maturity due to device and technical developments. Although the technical success rates of EUS-HGS are high, the rate of adverse events is not low, with stent migration still being reported despite many preventive efforts. In this review, we described technical tips for EUS-HGS related to bile duct puncture, guidewire insertion, fistula dilation, and stent deployment, along with a literature review. Additionally, we provided technical tips to improve the technical success of EUS-HGS.  相似文献

AIM: To evaluate the efficacy and safety of endoscopic papillary large diameter balloon dilation (EPLBD) following limited endoscopic sphincterotomy (EST) and EST alone for removal of large common bile duct (CBD) stones.METHODS: We retrospectively compared EST + EPLBD (group A, n = 64) with EST alone (group B, n = 89) for the treatment of large or multiple bile duct stones. The success rate of stone clearance, procedure-related complications and incidents, frequency of mechanical lithotripsy use, and recurrent stones were recorded.RESULTS: There was no statistically significant difference between the two groups regarding periampullary diverticula (35.9% vs 34.8%, P > 0.05), pre-cut sphincterotomy (6.3% vs 6.7%, P > 0.05), size (12.1 ± 2.0 mm vs 12.9 ± 2.6 mm, P > 0.05) and number (2.2 ± 1.9 vs 2.4 ± 2.1, P > 0.05) of stones or the diameters of CBD (15.1 ± 3.3 mm vs 15.4 ± 3.6 mm, P > 0.05). The rates of overall stone removal and stone removal in the first session were not significantly different between the two groups [62/64 (96.9%) vs 84/89 (94.4%), P > 0.05; and 58/64 (90.6%) vs 79/89 (88.8%), P > 0.05, respectively]. The rates of post-endoscopic retrograde cholangiopancreatography pancreatitis and hyperamylasemia were not significantly different between the two groups [3/64 (4.7%) vs 4/89 (4.5%), P > 0.05; 7/64 (10.9%) vs 9/89 (10.1%), P > 0.05, respectively]. There were no cases of perforation, acute cholangitis, or cholecystitis in the two groups. The rate of bleeding and the recurrence of CBD stones were significantly lower in group A than in group B [1/64 (1.6%) vs 5/89 (5.6%), P < 0.05; 1/64 (1.6%) vs 6/89 (6.7%), P < 0.05, respectively].CONCLUSION: EST + EPLBD is an effective and safe endoscopic approach for removing large or multiple CBD stones.  相似文献

Esophageal carcinosarcoma is a rare malignant tumor composing of both carcinomatous and sarcomatous elements. Endoscopic therapy is less invasive and may represent an alternative to esophagectomy for superficial esophageal carcinosarcoma. Here, we report a 61-year-old male who was diagnosed as esophageal carcinosarcoma and underwent endoscopic polypectomy with well tolerance and favorable prognosis. We also present a brief review of the literature.  相似文献
