Abstract   The variations of the aortic arch and its branches are rare. The surgical treatment of esophageal cancer would be challenged for combination with this anomaly. This study intends to review significant group cases to analyze the influence of this variation on esophagectomy. Methods From 2013 to 2019, 19 patients with aortic arch and brachiocephalic vessels variations underwent esophagectomy, accounting for 0.3% during the same period. The abnormalities were distributed as follows: left-sided aortic arch combined with aberrant right subclavian artery (LAA + ARSA) occurred 13 cases, right-sided aortic arch anomalies with mirror image arch branches (RAA + MIAB) in 1 case, and right-sided aortic arch combined with aberrant left subclavian artery (RAA + ALSA) in 5 case. Of the patients with LAA + ARSA, 11 patients underwent the McKeown esophagectomy, and 2 patients via transhiatal. All patients with RAA underwent left thoracotomy approach.Perioperative outcomes and long-term survival were analyzed. Results The tumors were mostly located in the upper and middle thorax (47.4% and 42.1%). The R0 resection rate was 89.5% (17/19). Recurrent laryngeal nerve injury occurred in 2 patients, anastomotic fistula in 1 patient. Two patients died within 30 days postoperatively. The yield of lymph nodes was 21.8 ± 9.4. The sampling rate of lymph nodes along the recurrent laryngeal nerve was 61.5% in LAA + ARSA group, while 16.7% in RAA group. Recurrence happened in 5 cases (29.4%), including 2 regional relapse. Four patients died after recurrence, with a median time to death of 20 months (range: 10–48 months). Conclusion For aortic arch and brachiocephalic artery variations in esophageal cancer, aberrant right subclavian artery and right-sided aortic arch are the most common types. The surgical strategy is closely related to the aortic arch position. Due to the combined variation of the recurrent laryngeal nerve, the upper mediastinal lymph nodes dissection would be conservative, but with acceptable oncologic results.

Abstract Description Background Lymphadenectomy along the left recurrent laryngeal nerve (RLN) in esophageal cancer is important for disease control but requires advanced dissection skills. Complete dissection of the lymph nodes along the left RLN in a safe manner is important. We demonstrate the reliable method for lymphadenectomy along the left RLN during thoracoscopic esophagectomy in the prone position (TEP). Methods This procedure is performed for all of resectable thoracic esophageal cancers. The essence of this method is to recognize the lateral pedicle as a two-dimensional membrane that inclu replicatedes the left RLN, lymph nodes around the nerve, and primary esophageal arteries. By drawing the proximal portion of the divided esophagus and the lateral pedicle, identification and reliable cutting of the primary esophageal arteries and distinguishing the left RLN from the lymph nodes are simplified. Results We performed 46 TEPs for esophageal cancer using this method with no conversion to an open procedure in 2015 at Kobe University. No intraoperative morbidity related to the left RLN was observed. The mean number of harvested lymph nodes along the left RLN was 6.9 ± 4.2. Left RLN palsy greater than Clavien-Dindo classification grade II occurred in 4 patients (8%), all of them were reversible. The incidence of lymph node metastasis along the left RLN was 22%. Conclusion Our method for lymphadenectomy along the left RLN during TEP is safe and reliable. It has a low incidence of left RLN palsy and provides sufficient lymph node dissection along the left RLN. Disclosure All authors have declared no conflicts of interest.

Abstract Aim The aim of this study is to establish a clinical predictive standard for lymph node metastasis at this location by retrospectively comparing the traditional imaging findings of RRLN lymph nodes in esophageal squamous cell carcinoma with postoperative pathology. Background The right recurrent laryngeal nerve (RRLN) is the zone most prone to lymph node metastasis of esophageal squamous cell carcinoma. Although the survival benefit is large after surgical dissection, however, the postoperative mortality rate is significantly increased if the nerve is injured. How to selectively perform lymph node dissection at this location has always been a clinical problem that needs to be addressed. In the past, clinical evaluations mostly used lymph node short diameter ≥1cm as the diagnostic criteria for metastasis, which significantly underestimated the actual clinical situation. Methods 308 patients with thoracic esophageal squamous cell carcinoma who underwent surgical treatment in Shanghai Chest Hospital from Jan 2018 to Dec 2018 were retrospectively analyzed. According to imaging 1mm layer thickness enhanced CT as a tool, the RRLN lymph node short diameter (ctNd) size was measured. All patients were divided into four groups: (A) CT images without RRLN lymph node, (B) CT images with RRLN lymph node was 0<ctNd<5mm, (C) CT images with RRLN lymph node was 5mm≤ctNd<10mm, (D) CT images with RRLN lymph node was ctNd≥10mm. The RRLN lymph node metastasis of each group was analyzed, and the influencing factors were analyzed to establish a predictive model. Results Among all patients, 87.6% of the patients had lymph nodes detected in the RRLN surgical specimens. The sampling rate was 14.5% (121/832), the RRLN lymph node metastasis rate was 19.48%, and the total lymph node metastasis rate was 48.7%. RRLN lymph nodes (57.1%) (A-132, B-43, C-125, D-9) were seen in the preoperative CT scan of 176 patients. The postoperative pathological RRLN lymph node metastasis rate was 9.1%, 18.6%, 27.2% and 66.7%, respectively (P=0.01). Multivariate analysis showed that ctNd, tumor location and N stage were risk factors for RRLN lymph node metastasis (P<0.05). The risk of upper esophageal cancer metastasis was higher than middle segment esophageal cancer (28.2% vs 18.6%, P<0.05). The higher the risk of right laryngeal lymph node metastasis was detected in the later N stage (cN0-13.2%, cN1-21.5%, cN2-46.7%, P<0.05). The 6.5mm short diameter of RRLN lymph nodes on CT scan is the critical value of metastasis at this position (sensitivity 50%, specificity 83.5%), and the higher the risk of metastasis was seen in the larger the short diameter (P<0.05). Conclusion More than 6.5mm short diameter in the CT scan image should be the clinical predictor of lymph node metastasis of the right recurrent laryngeal nerve. The higher risk of metastasis was seen in the greater short diameter. Upper esophageal cancer and multiple lymph node metastasis increase the risk of RRLN lymph node metastasis.

(1) Background: severe weight loss was reported to be related to unilateral vocal fold paralysis (UVFP) after esophagectomy and could thus impair survival. Concomitant radical lymph node dissection along the recurrent laryngeal nerve during esophageal cancer surgery is controversial, as it might induce UVFP. Early intervention for esophagectomy-related UVFP by administering intracordal injections of temporal agents has recently become popular. This study investigated the survival outcomes of esophagectomy for esophageal squamous cell carcinoma (ESCC) after the introduction of early injection laryngoplasty (EIL). (2) Methods: a retrospective review of patients with ESCC after curative-intent esophagectomy was conducted in a tertiary referral medical center. The necessity of EIL with hyaluronic acid was comprehensively discussed for all symptomatic UVFP patients. The survival outcomes and related risk factors of ESCC were evaluated. (3) Results: among the cohort of 358 consecutive patients who underwent esophagectomy for ESCC, 42 (11.7%) showed postsurgical UVFP. Twenty-nine of them received office-based EIL. After EIL, the glottal gap area, maximum phonation time and voice outcome survey showed significant improvement at one, three and six months measurements. The number of lymph nodes in the resected specimen was higher in those with UVFP than in those without UVFP (30.1 ± 15.7 vs. 24.6 ± 12.7, p = 0.011). The Kaplan–Meier overall survival was significantly better in patients who had UVFP (p = 0.014), received neck anastomosis (p = 0.004), underwent endoscopic resection (p < 0.001) and had early-stage cancer (p < 0.001). Multivariate Cox logistic regression analysis showed two independent predictors of OS, showing that the primary stage and anastomosis type are the two independent predictors of OS. (4) Conclusion: EIL is effective in improving UVFP-related symptoms, thus providing compensatory and palliative measures to ensure the patient’s postsurgical quality of life. The emerging use of EIL might encourage cancer surgeons to radically dissect lymph nodes along the recurrent laryngeal nerve, thus changing the survival trend.
