- Background
/Aims: Endoscopic mucosal resection with circumferential mucosal incision (CMI-EMR) may offer benefits comparable to those of endoscopic submucosal dissection (ESD), while requiring less technical proficiency than ESD.
Methods
We retrospectively compared the outcomes of CMI-EMR (n=34) and size-matched ESD (n=102), which were performed by a Korean endoscopist for colorectal epithelial lesions of 20–35 mm. Procedural parameters of CMI-EMRs performed by an American ESD novice ((n=30) were compared with those performed by the Korean endoscopist.
Results
The lesion size was 22.3±3.9 mm and 22.9±2.4 mm in the CMI-EMR and size-matched ESD groups, respectively (p=0.730). The resection time was 12.7±7.0 minutes in the CMI-EMR group and 45.6±30.1 minutes in the ESD group (p<0.001). The en bloc resection rate was 94.1% in the CMI-EMR group and 100% in the ESD group (p=0.061). There were no differences in the en bloc resection and complication rates of CMI-EMRs between a Korean and an American endoscopist.
Conclusions
For the treatment of moderate-size colorectal lesions, CMI-EMR showed a trend toward lower en bloc resection rate, but required shorter procedure time than ESD. CMI-EMR outcomes were similar when performed by a Korean ESD expert and an American ESD novice.

Patients with altered anatomy such as a Roux-en-Y anastomosis often present with various pancreaticobiliary problems requiring therapeutic intervention. However, a conventional endoscopic approach to the papilla is very difficult owing to the long afferent limb and acute angle of a Roux-en-Y anastomosis. Balloon-assisted enteroscopy can be used for endoscopic retrograde cholangiopancreatography (ERCP) in patients with altered anatomy. We experienced six cases of Roux-en-Y anastomosis with biliary problems, and attempted ERCP using single balloon enteroscopy (SBE). SBE insertion followed by replacement with a conventional endoscope was attempted in five of six patients. The papilla was successfully approached using SBE in all cases. However, therapeutic intervention was completed in only three cases because of poor maneuverability caused by postoperative adhesion. We conclude that in patients with Roux-en-Y anastomosis, the ampulla can be readily accessed with SBE, but longer dedicated accessories are necessary to improve this therapeutic intervention.

- Background/Aims
Although postpolypectomy fever (PPF) without colon perforation or hemorrhage is rare, its incidence and risk factors have not been investigated. The objective of this study was to analyze the incidence and risk factors for PPF among inpatients.
MethodsSeven patients with PPF were matched with 70 patients without PPF from a total of 3,444 patients who underwent colonoscopic polypectomy. The PPF incidence during index hospitalization after colonoscopy was calculated, and univariate and multivariate analyses were performed to calculate the adjusted odds ratios (ORs) for risk factors.
ResultsPPF without bleeding or perforation in the colon occurred in seven patients (0.2%). The median age was 58 years for cases and 61 years for controls. The median interval from polypectomy to occurrence of fever was 7 hours, and the median duration of fever was 9 hours. Polyp size >2 cm (adjusted OR, 1.08; 95% confidence interval [CI], 1.01 to 1.15; p=0.02) and hypertension (adjusted OR, 14.40; 95% CI, 1.23 to 180.87; p=0.03) were associated with a significantly increased risk of PPF. PPF increased the length of hospitalization.
ConclusionsAlthough the crude incidence of PPF is low, PPF may prolong hospitalization. Risk factors for PPF include hypertension and large polyps.

Real-time visualization of the molecular signature of cells can be achieved with advanced targeted imaging techniques using molecular probes and fluorescence endoscopy. This molecular optical imaging in gastrointestinal endoscopy is promising for improving the detection of neoplastic lesions, their characterization for patient stratification, and the assessment of their response to molecular targeted therapy and radiotherapy. In inflammatory bowel disease, this method can be used to detect dysplasia in the presence of background inflammation and to visualize inflammatory molecular targets for assessing disease severity and prognosis. Several preclinical and clinical trials have applied this method in endoscopy; however, this field has just started to evolve. Hence, many problems have yet to be solved to enable the clinical application of this novel method.
