Randomized Controlled Trial Comparative Study
Comparison of Analgesic Efficacy of Laparoscope-Assisted and Ultrasound-Guided Transversus Abdominis Plane Block after Laparoscopic Colorectal Surgery: A Randomized, Single-Blind, Non-Inferiority Trial.
Transversus abdominis plane (TAP) block has been used as a component of multimodal analgesia after abdominal operation. We introduced a new laparoscope-assisted TAP (LTAP) block technique using intraperitoneal injection and compared its analgesic effect with that of an ultrasound-guided TAP (UTAP) block in terms of postoperative pain control. ⋯ These results show our new LTAP block technique was non-inferior to the ultrasound-guided technique in providing a TAP block after laparoscopic colorectal operation.

Randomized Controlled Trial
Evaluation of Gastric Microcirculation by Laser Speckle Contrast Imaging during Esophagectomy.
Thoracic epidural anesthesia (TEA) may provoke hypotension, and that, as well as the use of vasopressors and the surgical technique, could affect splanchnic microcirculation, in which the surgical target organ is of particular interest. This study used laser speckle contrast imaging (LSCI) to monitor gastric microcirculation during esophagectomy. ⋯ During esophagectomy, gastric microcirculation can be followed in real-time by LSCI. Flow changes in the stomach seemed related more to surgery than to TEA/vasopressor support. Laser speckle contrast imaging could form basis for directing procedures to maintain the microcirculation.
