While retrospective studies aiming to achieve long-term survival in invasive IPMC patients have been reported, the rarity of invasive IPMC has resulted in small-scale datasets, leading to low levels of evidence. Consequently, the utility of adjuvant therapy after surgery, neoadjuvant therapy (NAT) before surgery, and treatments for postoperative recurrence in invasive IPMC remains unclear, with treatment strategies varying by institution—ranging from surgical resection alone to approaches based on conventional pancreatic cancer treatment. Recently, several large-scale multicenter studies on invasive IPMC have been reported. These studies suggested that while adjuvant therapy after surgery may not be beneficial for all invasive IPMC patients, it could potentially extend survival in cases with advanced-stage disease. Regarding NAT before surgery for invasive IPMC, the number of reported cases is extremely limited, and no definitive evidence has been established. For postoperative recurrence of invasive IPMC, some studies have indicated that administering treatment may prolong survival.

Multivariate analysis confirmed that the left lateral decubitus position (odds ratio: 4.24; 95% confidence interval: 1.09–13.4, <i>p</i> = 0.019) and not using video laryngoscope during intubation (odds ratio: 9.51; 95% confidence interval: 2.94–15.9, <i>p</i> = 0.001) were independent risk factors for recurrent laryngeal nerve palsy diagnostic discrepancies.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>Adequate contact between the intubation tube and vocal cord muscles is crucial for effective intraoperative nerve monitoring during esophagectomy.

If untreated, fibrosis can progress to cirrhosis, increasing the risk of liver cancer or failure.
