Fine-needle aspiration (FNA) cytology has been the preferred technique for procuring tissue at endoscopic ultrasound (EUS) procedures for the past 25 years. To overcome some of the limitations of FNA cytology, fine-needle biopsy (FNB) has been recently developed to yield histological tissue. Main objective was to compare the diagnostic yield of FNB compared to FNA for both onsite and offsite specimen assessment. ⋯ Given these promising findings, in the future, EUS-guided FNB will likely be the preferred technique for sampling of solid mass lesions.

Multicenter Study Clinical Trial Observational Study
Factors related to difficult self-expandable metallic stent placement for malignant colonic obstruction: A post-hoc analysis of a multicenter study across Japan.
Colorectal cancer patients often present with large bowel obstruction. Elective placement of a self-expandable metallic stent (SEMS) can relieve obstruction, but can be challenging. Previous studies have compared cases by outcomes only, but the present study investigated successful cases only to identify factors related to prolonged and difficult SEMS placement in patients with malignant colonic obstruction. ⋯ Clinicians must anticipate technical challenges in cases with peritoneal carcinomatosis, a CROSS score of 0, or expansive strictures; such cases require experienced clinicians to carry out SEMS placement.

Review Meta Analysis Comparative Study
Comparison of propofol monotherapy and propofol combination therapy for sedation during gastrointestinal endoscopy: A systematic review and meta-analysis.
Previous randomized controlled trials have reported conflicting findings comparing propofol combination therapy (PCT) with propofol monotherapy (PMT) for sedation of patients undergoing gastrointestinal endoscopy. Therefore, a systematic review was carried out to compare the efficacy and safety of PCT and PMT in such patients. ⋯ PCT showed comparable efficacy and safety to PMT with respect to respiratory complications, hypotension and arrhythmia, recovery time, procedure duration, patient satisfaction, and doctor satisfaction. However, the average dose of propofol used was higher in PMT.

Comparative Study
Usefulness of argon plasma coagulation ablation subsequent to endoscopic snare papillectomy for ampullary adenoma.
Endoscopic snare papillectomy (ESP) is an effective treatment for ampullary adenoma. Argon plasma coagulation (APC) is widely used as an additional method to control bleeding or ablate the residual tumor. However, the efficacy of this procedure has not yet been fully evaluated. This study aimed to evaluate the usefulness of APC as an additional method to ESP. ⋯ Additional APC during ESP may have a beneficial effect by decreasing bleeding rate without harmful effects.
