Overview
The objective is to investigate the safety and effectiveness of rhomboid intercostal and subserratum plane (RISS) block for postoperative analgesia after minimally invasive McKeown esophagectomy (MIE-McKeown).
Description
Rhomboid intercostal and subserratum plane block (RISS) is a nerve block technique in which local anesthetics are injected into the rhomboid-intercostal muscle planes and the serratus anterius-intercostal muscle planes, and the intercostal nerve is blocked by diffusion of local anesthetics. It is confirmed that RISS can provide analgesia not only in the front half of the chest, but also in the upper abdomen. However, the efficacy of RISS in minimally invasive surgery for esophageal cancer has not been proven. The investigators placed catheters on the RISS plane and continuously injected local anesthetics to investigate whether RISS is effective and safe in minimally invasive esophageal cancer surgery.
