Filter by:Colorectal cancer is one of the most malignancies worldwide. The dominant clinical research strategy of LARC includes neoadjuvant chemoradiotherapy before radical surgery followed combined with adjuvant treatment. Approximately 15% to 20% of the patients after nCRT can achieve a pathologic complete response (pCR)---no residual tumor is reported at histology after a standard resection. Some researchers suggest that those patients with pCR can be spared the morbidities of surgery instead by a nonoperative approach---watch- and-wait(W&W). However, neither FDG-PET, MRI, CT, nor enteroscopy can accurately determine a pCR. EUS-FNA has been an important technique for the diagnosis of rectal cancer for its high accuracy and little harm. However, data on the TRUS-FNA for the cytologic diagnosis of pCR in rectal cancer is scarce. Our hypothesis is that adding transrectal ultrasound-guided fine needle aspiration (TRUS-FNA) compared with enteroscopy , MR, and CT alone can improve the accuracy of predicting pCR after nCRT.Therefore, the aim of the study is to assess the performance characteristics of EUS-FNA in this setting.
The objective of this randomized cross-over trial is to evaluate whether Heparin based wet suction technique, compared with dry suction technique, shall present a higher quality tissue core by using quantitative macroscopic and microscopic scale.
The purpose of this study is to evaluate the efficacy and safety of chemotherapeutic pancreatic cyst ablation using ethanol lavage followed by the infusion of a dual-agent chemotherapeutic cocktail (paclitaxel + gemcitabine) compared with alcohol-free saline lavage followed by infusion of the same dual-agent chemotherapeutic cocktail (paclitaxel + gemcitabine) for the ablation of pancreatic cystic neoplasms using endoscopic ultrasound guided fine needle infusion (EUS-FNI) for agent delivery.
EUS-guided fine needle aspiration (EUS-FNA) is a safe and effective method for diagnosing pancreatic and peripancreatic solid masses. The aim of this study is to compare the two aspiration methods in EUS-FNA: negative-pressure suction with syringe vs. capillary sampling with stylet slow-pull technique. We will evaluate the diagnostic adequacy and accuracy of the specimens obtained by EUS-FNA with two aspiration methods.
