Randomized Controlled Trial Multicenter Study
CO2 insufflation during single-balloon enteroscopy: a multicenter randomized controlled trial.
Carbon dioxide (CO2) insufflation has previously been shown to have advantages over air insufflation in terms of procedure-related pain and oral insertion depth during double-balloon enteroscopy. The aim of this prospective study was to evaluate the performance of CO2 vs. air insufflation during single-balloon enteroscopy. ⋯ This study demonstrated an advantage of using CO2 insufflation during single-balloon enteroscopy in patients with a history of previous abdominal surgery. Overall, single-balloon enteroscopy was a well-tolerated procedure that may benefit from the use of CO2 insufflation to reduce post-procedural pain.

Randomized Controlled Trial Comparative Study
A randomized comparison of target-controlled propofol infusion and patient-controlled sedation during ERCP.
Propofol is widely used during endoscopic retrograde cholangiopancreatography (ERCP) but high doses are recognized as a risk factor for sedation-related complications. The aim of this study was to compare target-controlled infusion (TCI) with patient self-administration (patient-controlled sedation, PCS) of propofol during ERCP. Propofol consumption, the ease of ERCP performance, and speed of recovery were recorded. ⋯ No benefits of TCI over PCS could be demonstrated in this study. We recommend considering PCS as a feasible option for propofol administration during ERCP because of its ease of use, high success rate, reduced consumption of propofol, and faster recovery.

Randomized Controlled Trial Comparative Study
Target-controlled infusion vs. manually controlled infusion of propofol with alfentanil for bidirectional endoscopy: a randomized controlled trial.
The best anesthesia methods for analgesia and sedation during gastrointestinal endoscopy are still debated. The aim of this study was to compare the recovery time, clinical presentations, and satisfaction between target-controlled infusion (TCI) and manually controlled infusion (MCI) in same-day bidirectional endoscopy (esophagogastroduodenoscopy followed by colonoscopy). ⋯ CGMH IRB Identifier 97-0969B.

Review Meta Analysis
Predicting lymph node metastasis in pT1 colorectal cancer: a systematic review of risk factors providing rationale for therapy decisions.
Population screening for colorectal cancer (CRC) is expected to increase the number of pT1 CRCs. Local excision is an attractive treatment option, but is only oncologically safe in the absence of lymph node metastasis (LNM). A systematic review of the predictive value of pathological risk factors for LNM in pT1 CRC was conducted to provide data for an evidence-based decision regarding follow-up or radical surgery after local excision. ⋯ The absence of lymphatic invasion, budding, submucosal invasion ≥ 1 mm, and poor histological differentiation were each associated with low risk of LNM. Risk stratification models integrating these factors need to be investigated further.
