394. USEFULNESS OF INTRAOPERATIVE RECURRENT LARYNGEAL NERVE MONITORING IN REDUCING RECURRENT LARYNGEAL NERVE PARALYSIS AFTER ROBOT-ASSISTED THORACOSCOPIC ESOPHAGECTOMY

Abstract Background Robot-assisted thoracoscopic esophagectomy (RAMIE) is a precise and safe procedure with its advantages. On the other hand, RAMIE has several disadvantages. The lack of tactile function must be fully recognized, surgical procedures take characteristics into account. We examined whether findings obtained by intraoperative recurrent nerve monitoring (NIM) are useful in reducing laryngeal paralysis (RLNP) after RAMIE. Methods Overall, 81 cases through February 2023 were included study. NIM was performed 41 patients first term using combination continuous intermittent methods (NIM group). In subsequent 40 patients, not (non-NIM group) order to confirm learning effect shorten operation time. RLNP confirmed symptoms postoperative laryngoscopy. Clinical oncological factors short-term outcomes two groups compared. Results All occurred on left side. Six (14.6%) group had Grade 1 or higher RLNP. causes all found during thoracic manipulation; 4 over-traction RLN 2 crush injury robotic forceps. There significant decrease higher; (9.7%) 0 non-NIM (p = 0.04). group, there reduction operative time, total blood loss. Conclusion made us aware maneuvers that cause Although proficiency technique may have played role later period, avoidance risky due from thought contributed
