Video capsule endoscopy
The American Society for Gastrointestinal Endoscopy (ASGE) Technology Committee provides reviews of existing, new, or emerging endoscopic technologies that have an impact on the practice of GI endoscopy. Evidence-based methodology is used, with a MEDLINE literature search to identify pertinent clinical studies on the topic and a MAUDE (U.S. Food and Drug Administration Center for Devices and Radiological Health) database search to identify the reported adverse events of a given technology. Both are supplemented by accessing the “related articles” feature of PubMed and by scrutinizing pertinent references cited ...

EUS-guided verteporfin photodynamic therapy for pancreatic cancer
Locally advanced pancreatic cancer (LAPC) often causes obstruction. Verteporfin photodynamic therapy (PDT) can feasibly “debulk” tumor more safely than noncurative surgery and has multiple advantages over older PDT agents. We aimed to assess the feasibility of EUS-guided verteporfin PDT in ablating nonresectable LAPC. (Source: Gastrointestinal Endoscopy)

Laparoscopic lymph node sampling: a new concept for patients with high-risk early esophagogastric junction cancer resected endoscopically
Endoscopic resection is considered as curative treatment for early upper GI cancers under certain histologic (low-risk) criteria. In tumors not completely fulfilling these criteria but resected R0 endoscopically, esophagectomy is still advised due to an increased risk of lymph node (LN) metastases. However, the benefit-risk ratio especially in elderly patients at higher risk for radical surgery can be debated. We now present the outcome of our case series of laparoscopic lymph node sampling (LLS) in patients with T1 esophagogastric junction tumors, which had been completely resected by endoscopy but did not fulfill the low...

Outcomes of hybrid technique using endoscopic mucosal resection and endoscopic full-thickness resection for polyps not amenable to standard techniques (with video)

Incidence of microscopic residual adenoma after complete wide-field endoscopic resection of large colorectal lesions: evidence for a mechanism of recurrence
Endoscopic mucosal resection (EMR) of large ( ≥2 cm) nonpedunculated colorectal polyps (LNPCP) is associated with high rates of recurrent/residual adenoma, possibly due to microadenoma left at the margin of resection. Data supporting this mechanism are required. We aimed to determine the incidence of residual microadenoma at the defect margin and base after EMR. (Source: Gastrointestinal Endoscopy)

K-ras point mutation detection as an ancillary diagnostic biomarker: 1 step forward and 2 steps back?
The diagnosis of pancreatic ductal adenocarcinoma (PDAC) is suboptimal, largely because of the hostile tumor microenvironment composed of dense fibrotic stroma and the presence of necrosis, leading to a tumor cell density of only 5% to 20%. The presence of well-differentiated tumor cells also complicates a cytologic assessment.1 The overall sensitivity and specificity of an EUS-FNA cytologic examination is reported to range from 79% to 95% and 86%, respectively.2,3 The uncertainty whether a result represents a false negative finding complicates medical care and was reported to be approximately 13% when the Papanicolaou Soc...

Portal pressure measurement: Have we come full circle?
Portal hypertension develops during the natural history of cirrhosis and is responsible for its main clinical adverse events, including gastroesophageal variceal bleeding, ascites, hepatorenal syndrome, and hepatic encephalopathy. The degree of portal hypertension is an independent factor for survival among patients with cirrhosis.1 The most common but indirect method of assessing the portal gradient is the hepatic venous pressure gradient (HVPG), which is calculated as the difference between free hepatic vein pressure and wedged hepatic vein pressure (WHVP).

EUS-guided gallbladder drainage is as good as laparoscopic cholecystectomy for symptomatic cholelithiasis: Wait! …what?!
Gallbladder interventions have evolved greatly over the past several hundred years. Because of the belief that humans could not live without a gallbladder, the earliest surgical intervention was cholecystostomy with removal of fluid and stones.1 The first successful cholecystectomy was performed in Germany in 1882.1 Nearly 100 years later, the first percutaneous cholecystostomy was performed in 19802 followed by the first laparoscopic cholecystectomy in 1985.1 Although transpapillary gallbladder drainage was described in 1990,3 it has not been widely accepted outside of tertiary centers because of technical complexities an...

Evaluation of preparation methods for colonoscopy
The meta-analysis by Zhang et  al1 has important implications given the crucial role preparation plays in ensuring a high-quality colonoscopy.2 Scales of cleanliness are at their core subjective, validation studies (which had relatively low adenoma detection rates [ADRs]3) notwithstanding. We suggest that comparison of cleaning methods would be more objective and valid if ADRs (and right-sided serrated polyp detection rates) in routine first-time average-risk screening colonoscopies were used as dependent variables, with the proviso that the ADRs of the performing colonoscopists be high—we would suggest in exces...

A knife plus a snare, but how will it fare?
The introduction of EMR revolutionized the gastroenterologist ’s ability to resect larger GI lesions, especially colonic polyps. However, lesions>20  mm in diameter cannot reliably be removed en bloc by EMR.1 This results in a piecemeal resection, which renders histopathologic margins unevaluable and is associated with higher rates of recurrence, warranting closer endoscopic surveillance and potentially additional therapy. Endoscopic submucosal dissection (ESD) is a technique pioneered in Japan that allows for en bloc resection, generally without the size limitations of EMR, and can spare the patient surgical...
