Enhancing Perioperative Care in Esophageal Cancer Surgery: Advances and Approaches

Background Esophageal cancer surgery is known for its high invasiveness, which results in significant postoperative complications. With the advancement of minimally invasive surgery (MIS) and Enhanced Recovery After Surgery (ERAS) protocols, there has been a reduction in recovery time and postoperative complications. Despite these improvements, patients undergoing esophagectomy still face considerable challenges in recovery, and methods to reduce inflammation, promote faster recovery, and improve long-term outcomes are essential. Investigating new perioperative strategies, including the use of preoperative steroids, rehabilitation programs, and adjunctive agents like cystine and theanine, holds promise for further enhancing recovery. Methods This study focuses on the effects of minimally invasive thoracoscopic esophagectomy, preoperative steroid administration, and early rehabilitation on recovery following esophageal cancer surgery. A randomized controlled trial evaluated the perioperative use of cystine and theanine in reducing the inflammatory response and improving recovery. The impact on postoperative complications, 6-minute walk test (6MWT) performance, and quality of recovery (QoR-40) scores were analyzed. Patients were also monitored for inflammatory markers, lymphocyte count, and other relevant clinical parameters throughout the perioperative period to assess the effectiveness of these interventions. Results Minimally invasive surgery in the prone position resulted in less blood loss, shorter ICU stays, and reduced postoperative pneumonia rates compared to traditional lateral position surgery. Preoperative steroid administration significantly suppressed postoperative tachycardia, accelerated fluid balance recovery, and reduced inflammatory cytokines. In the cystine-theanine trial, participants in the treatment group showed improved 6MWT results and better QoR-40 scores by postoperative day 13. Additionally, inflammatory markers like neutrophil count and CRP levels were significantly lower in the cystine-theanine group, supporting the role of these agents in reducing postoperative inflammation and promoting recovery. Conclusion The combination of minimally invasive surgery, preoperative steroids, and early rehabilitation significantly improves recovery in esophageal cancer surgery. Perioperative administration of cystine and theanine is a promising adjunctive therapy, effectively reducing postoperative inflammation, enhancing recovery outcomes, and improving quality of life. These findings support the broader implementation of these strategies to further optimize postoperative care and accelerate recovery in patients undergoing esophagectomy.
