Predictive factors for refractory anastomotic stricture after cervical triangular anastomosis with gastric conduit reconstruction through the posterior mediastinum in minimally invasive esophagectomy. J Gastrointest Surg 2024:S1091-255X(24)00632-2. [PMID: 39303904 DOI: 10.1016/j.gassur.2024.09.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2024] [Revised: 08/28/2024] [Accepted: 09/16/2024] [Indexed: 09/22/2024]
Abstract
BACKGROUND After esophagectomy, anastomotic strictures disturb food passage and increase the incidence of aspiration pneumonia. Multiple endoscopic balloon dilatations are required for stricture treatment. Therefore, long-term quality of life and nutritional status may be adversely affected. This study aimed to identify risk factors for strictures after cervical triangular anastomosis using a gastric conduit among patients who underwent minimally invasive esophagectomy (MIE). METHODS A total of 188 patients who underwent MIE for esophageal cancer between 2010 and 2020 at Kobe University Hospital were retrospectively examined. The incidence of strictures, number of dilatations for stricture, and time to stricture diagnosis were evaluated. Next, the potential independent risk factor for refractory strictures requiring more than 5 endoscopic balloon dilatations was clarified. RESULTS The study included 188 patients who satisfied the inclusion criteria. Anastomotic strictures were observed in 44 patients (23%). Neoadjuvant chemotherapy was significantly more common in patients with stricture than in patients without stricture (75% vs 58%, respectively; P = .041). The median number of endoscopic balloon dilatations was 5 (IQR, 1-31). Of note, 30 patients (68%) underwent their first dilatation within 3 months after MIE. In univariate and multivariate analyses, < 69 days from surgery to first endoscopic balloon dilatation was an independent risk factor for stricture requiring more than 5 endoscopic balloon dilatations after cervical triangular anastomosis in MIE (hazard ratio, 9.483; 95% CI, 2.220-54.274; P = .002). CONCLUSION Early postoperative anastomotic stricture might become refractory, and an appropriate treatment plan should be developed.

Abstract
BACKGROUND Cervical esophagogastric anastomosis is conventionally performed using the McKeown esophagectomy. However, an optimal anastomotic technique has not yet been established. This study aimed to compare the clinical outcomes of triangular anastomosis (TA) and totally mechanical Collard anastomosis (TMCA) for cervical esophagogastric anastomosis during minimally invasive esophagectomy with gastric conduit reconstruction through the retrosternal route. METHODS In this matched- cohort study, 117 patients who underwent minimally invasive esophagectomy between 2019 and 2024 were divided into TA and TMCA groups. The TA technique was performed between September 2019 and December 2021, and the TMCA technique was performed between January 2022 and January 2024. We then compared the surgical outcomes and postoperative complications (pneumonia, recurrent laryngeal nerve palsy, anastomotic leakage, and stricture) between the two groups. RESULTS Propensity score matching revealed that 40 patients were included in both the TA and TMCA groups. The rates of pneumonia, recurrent laryngeal nerve palsy, and anastomotic leakage were not significantly different between the two groups. However, the rate of anastomotic stricture was lower in the TMCA than in the TA group (2.5% vs. 27.5%, respectively, P = 0.003). CONCLUSIONS Compared with the TA technique, the TMCA technique reduced the rate of anastomotic stricture when performing cervical esophagogastric anastomosis during minimally invasive esophagectomy with gastric conduit reconstruction through the retrosternal route.

Abstract
PURPOSE Esophageal cancer is a lethal tumor typically treated by neoadjuvant chemotherapy and surgery. For patients undergoing esophagectomy, postoperative enteral nutrition is important in preventing complications. Sarcopenia is associated with poor postoperative outcomes in esophageal cancer. In this study, we evaluated the benefits of tube feeding intervention and compared its short- and long-term outcomes in patients who underwent esophagectomy. METHODS Propensity score matching was performed in 303 patients who underwent esophagectomy at Kobe University Hospital between 2010 and 2020. Patients were divided into feeding and nonfeeding jejunostomy tube groups (n = 70 each). The feeding jejunostomy tube group was further divided into long-term (≥ 60 days) and short-term (< 60 days) subgroups. The groups were then retrospectively compared regarding postoperative albumin levels, body weight, and psoas muscle area and volume. RESULTS In the long-term feeding jejunostomy tube group, anastomotic leakage (p = 0.013) and left laryngeal nerve palsy (p = 0.004) occurred frequently. There were no significant between-group differences in postoperative albumin levels, body weight, or psoas muscle area. However, significant psoas muscle volume recovery was confirmed in the long-term jejunostomy tube group at 6 months postoperatively (p = 0.041). CONCLUSIONS Tube feeding intervention after minimally invasive esophagectomy may attenuate skeletal muscle mass loss and help prevent sarcopenia.

Comparison of two different methods for lymphadenectomy along the left recurrent laryngeal nerve by minimally invasive esophagectomy in patients with esophageal squamous cell carcinoma: a prospective randomized trial. Int J Surg 2024; 110:159-166. [PMID: 37737902 PMCID: PMC10793764 DOI: 10.1097/js9.0000000000000788] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Accepted: 09/10/2023] [Indexed: 09/23/2023]
Abstract
BACKGROUND Lymph nodes along the left recurrent laryngeal nerve (LRLN) is thought to be highly involved in esophageal cancer. Given the unique anatomical positioning of the nerve, performing lymphadenectomy in this region requires advanced techniques within limited working space. Meanwhile, high incidence of morbidity and mortality is associated with lymphadenectomy. Although several methods have been applied to reduce the technical requirement and the incidence of postoperative complication, the optimal method remains controversial. METHODS This study was a single-center, prospective, randomized trial to investigate the utility of lymphadenectomy along the LRLN during the minimally invasive esophagectomy in esophageal squamous cell carcinoma patients by comparing the surgical outcome, postoperative complication, survival rate, and quality of life (QoL) between the retraction method (RM) and the suspension method (SM) in patients with esophageal cancer from June 2018 to November 2020. QoL was assessed according to questionnaire: EQ-5D-5L. RESULTS Of 94 patients were enrolled and randomized allocated to RM and SM group equally. Characteristics did not differ between groups. The duration of lymph node dissection along LRLN was significant longer in SM group ( P <0.001). No difference was observed about postoperative complications. One of in-hospital death was occurred in each group ( P >0.999). Patients in neither of groups exhibiting difference about 3-year disease-free survival rate ( P =0.180) and overall survival rate ( P =0.430). No difference was observed in postoperative QoL between groups at different time points (all, P >0.05). CONCLUSION Both methods of lymph node dissection along the LRLN during minimally invasive esophagectomy in esophageal squamous cell carcinoma patients are technically feasible and safe. The RM appears more favorable in terms of reducing surgical duration compared to the SM.

Abstract
BACKGROUND In the context of esophageal cancers, lymph nodes located along the left recurrent laryngeal nerve (RLN) exhibit significant involvement, posing significant challenges for lymphadenectomy. The objective of this study is to assess the safety and efficacy of a novel technique for lymphadenectomy called "elastic suspension of left RLN" method, comparing it with the conventional approach. METHODS Between January 2016 and June 2020, a total of 393 patients who underwent minimally invasive esophagectomy with gastroplasty and cervical esophagogastric anastomosis were enrolled in the study. Among them, 291 patients underwent the "elastic suspension of left RLN" method, while 102 patients underwent the conventional method. We compared the number of harvested lymph nodes along the left RLN and assessed postoperative complications between these two groups. Additionally, the overall survival (OS) rate was calculated and analyzed for the entire cohort. RESULTS In comparison to the conventional group, the elastic suspension group exhibited a higher yield of harvested lymph nodes along the left RLN (5.36 vs 3.07, P < 0.001). Moreover, the incidence of postoperative hoarseness was lower in the elastic suspension group (10.65% vs 18.63%, P = 0.038). The average duration of lymphadenectomy along the left RLN was 11.85 min in the elastic suspension group and 11.51 min in the conventional group, although this difference was not statistically significant (P = 0.091). Notably, the overall 5-year OS was markedly higher in the elastic suspension group compared to the conventional group (64.1% vs. 50.1%, P = 0.020). CONCLUSIONS The findings suggest that the novel "elastic suspension of left RLN" method for lymphadenectomy along the left RLN in minimally invasive esophagectomy is both safe and effective. This technique holds promise for widespread adoption in esophagectomy procedures.

Abstract
BACKGROUND The effect of lymphadenectomy around the recurrent laryngeal nerve (RLN) in open esophagectomy has been demonstrated with the efficacy index (EI). However, it remains unclear whether this effect exists for minimally invasive esophagectomy (MIE) in the prone position. The purpose of this study was to clarify whether the upper mediastinal lymphadenectomy contributed to improved prognosis in patients with esophageal squamous cell carcinoma. STUDY DESIGN This study included 339 patients with esophageal squamous cell carcinoma treated with MIE in the prone position at Kobe University or Hyogo Cancer Center, Japan, from 2010 to 2015. EIs for each station, correlations between metastatic lymph nodes around the left RLN and RLN palsy, and survival of patients with and without upper mediastinal lymphadenectomy were investigated. RESULTS Among 297 patients treated with upper mediastinal lymphadenectomy, Clavien- Dindo grade ≥ II left RLN palsy occurred in 59 patients (20%). Overall, EIs for the right RLN (7.4) and left RLN (6.6) were higher than EIs for other stations. For patients with upper-third or middle-third tumors, the trend was stronger. Left RLN palsy was more likely in patients with metastatic lymph nodes around the left RLN than in those without (44% vs 15%, p < 0.0001). After propensity score-matching, 42 patients were included in each group with and without upper mediastinal lymphadenectomy. In survival analyses, the 5-year overall survival rates were 55% vs 35% and cause-specific survival rates were 61% vs 43% for the patients with and without upper mediastinal lymphadenectomy respectively. Significant differences were confirmed in survival curves (overall survival: p = 0.03; cause-specific survival: p = 0.04, respectively). CONCLUSIONS Upper mediastinal lymphadenectomy contributes to improved prognosis with high EIs in MIE in the prone position.

Abstract
BACKGROUND Because the robotic arm is located on the dorsal side of the patient, when the esophagus is pulled dorsally for the left recurrent nerve lymph node (LRLN) dissection, the robotic arm interferes with the surgical field. This made it difficult to prepare for the left recurrent lymph node dissection. We developed LRLN dissection in robotic surgery with natural space creation by physiological organ movement and evaluated the short-term results. METHODS In this retrospective study, we analyzed 102 cases of robot-assisted thoracoscopic subtotal esophagectomy (RATE) among radical subtotal esophagectomies performed between December 2018 and December 2022 using medical records. LRLN dissection is preceded by a dissection of the esophagus from the trachea. Leaving the esophagus on the vertebral side and away from the trachea resulted in a physiological elevation of the esophagus, providing space between the trachea and esophagus. RESULTS The thoracic surgery time in RATE was 181 (115-394) min. The number of LRLNs dissected was 4 (1-14). Six patients (6%) had a postoperative recurrence in the mediastinal lymph nodes. Seven patients (7%) had grade ≥ 1 left recurrent nerve palsy. CONCLUSIONS LRLN dissection with RATE using natural space creation was performed safely with a sufficient number of dissected lymph nodes and little left recurrent nerve palsy.

Efficacy and Postoperative Outcomes of Laparoscopic Retrosternal Route Creation for the Gastric Conduit: Propensity Score-Matched Comparison to Posterior Mediastinal Reconstruction. Ann Surg Oncol 2023; 30:4044-4053. [PMID: 37088861 DOI: 10.1245/s10434-023-13345-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Accepted: 02/19/2023] [Indexed: 04/25/2023]
Abstract
BACKGROUND Retrosternal reconstruction has lower risks for severe postoperative morbidities, such as gastro-tracheal fistula or esophageal hiatal hernia. We have previously reported the laparoscopic retrosternal route creation (LRRC) method, but its safety and efficacy remain unclear. METHODS In total, 374 patients with esophageal carcinoma who underwent minimally invasive McKeown esophagectomy in the prone position between 2010 and 2021 were retrospectively reviewed. We performed a propensity score-matched analysis with the simple, nearest-neighbor method and no calipers to compare postoperative outcomes and reconstructed gastric conduit functionality between patients who underwent LRRC and counterparts who underwent posterior mediastinal reconstruction. RESULTS After matching, 62 patients were included in the laparoscopic retrosternal group (LR group) or posterior mediastinal group (PM group). No significant differences were observed between the groups, apart from the number of robot-assisted surgeries, the extent of lymph node dissection, and the method of cervical anastomosis. There were no significant differences in the incidence of Clavien-Dindo grade ≥ 2 complications. Gastro-tracheal fistula (n = 1) and esophageal hiatal hernia (n = 2) occurred in the PM group but not in the LR group. There were no differences in the incidence of pulmonary embolism between the groups (5% vs. 5%). The postoperative anastomotic stenosis rate was similar (16% vs. 27%, p = 0.192). Endoscopic findings of reflux esophagitis (modified Los Angeles classification ≥ M) at 1 year after surgery were significantly better in the LR group (p = 0.037). CONCLUSIONS LRRC for gastric conduit reconstruction is safe and valuable. It is associated with good reconstructed gastric conduit function.

The Influence of Preoperative Smoking Status on Postoperative Complications and Long-Term Outcome Following Thoracoscopic Esophagectomy in Prone Position for Esophageal Carcinoma. Ann Surg Oncol 2023; 30:2202-2211. [PMID: 36539581 DOI: 10.1245/s10434-022-12898-y] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Accepted: 11/12/2022] [Indexed: 03/22/2023]
Abstract
BACKGROUND Esophagectomy for esophageal carcinoma is associated with higher morbidity and mortality rates than other gastrointestinal surgeries. Smoking is an established risk factor for postoperative complications after esophagectomy. This study aimed retrospectively to investigate the impact of smoking status on short- and long-term outcomes for patients undergoing thoracoscopic esophagectomy in the prone position (TEP) for esophageal carcinoma. METHODS In this study, 234 patients with esophageal carcinoma who underwent TEP between 2012 and 2020 were divided into two groups based on smoking status (current or non-current smokers and the Brinkman index) by patients' declarations. Postoperative complications (Clavien-Dindo classification grade ≥2), overall survival (OS), and disease-free survival (DFS) were compared between smoking statuses. RESULTS The rates of postoperative complications did not differ significantly between the two groups (current smoker vs non-current smoker; Brinkman index ≥800 vs <800). The rate of postoperative pneumonia was higher in the combination group of current and higher Brinkman index (≥800) smokers than in the other group (25.0 % vs 11.8 %; P = 0.036). Multivariate analysis showed that smoking status was an independent risk factor for postoperative pneumonia (hazard ratio, 0.41; 95 % confidence interval, 0.18-0.93; P = 0.037). According to the long-term outcomes, no significant differences in OS and DFS were observed between the smoking statuses. CONCLUSIONS The combination of current smoking and heavy smoking history is a risk factor for postoperative pneumonia in patients who have esophageal carcinoma treated with TEP, although no correlation was observed between the long-term outcomes and smoking status.

Surg Endosc 2022; 36:8834-8842.

Abstract
BACKGROUND Many patients with esophageal squamous cell carcinoma (ESCC) have obstructive ventilatory disorder (OVD), which is considered a risk factor for postoperative pneumonia. It has been reported that thoracoscopic esophagectomy in the prone position (TEP) is less invasive and is associated with fewer postoperative respiratory complications compared with open esophagectomy. This matched-cohort study aimed to elucidate the safety and oncologic outcomes of ESCC patients with OVD who undergo TEP. METHODS In this matched-cohort study, 237 patients with ESCC who underwent TEP between 2010 and 2018 were divided into two groups based on forced expiratory volume in 1 s/forced vital capacity. Postoperative complications (Clavien-Dindo classification grade II or higher), overall survival (OS), and disease-free survival (DFS) were compared between the two groups. RESULTS Based on their propensity scores, 75 patients with normal respiratory function (NRF) and 75 with OVD were selected. The rates of postoperative pneumonia were not significantly different between the two groups (NRF group vs OVD group: 18.7% vs 18.7%; P = 1.000). The rates of recurrent laryngeal nerve palsy and anastomotic leakage were also not significantly different (NRF group vs OVD group: 12.0% vs 18.7%, P = 0.365; 18.7% vs 18.7%, P = 1.000). The 5-year OS and DFS rates in the NRF vs OVD groups were 66.2% vs 54.9% and 63.5% vs 52.9%, respectively, with no significant differences (P = 0.421, 0.197). CONCLUSIONS TEP can be safely performed on ESCC patients with OVD and can result in an oncological efficiency equal to that of the NRF group.

Abstract
BACKGROUND Postoperative complications affect long-term prognosis in patients with esophageal squamous cell carcinoma (ESCC). Although a comprehensive estimator can predict long-term prognosis, the Clavien-Dindo classification system, a widely used approach to evaluate complications, assesses each complication individually. We aimed to clarify the utility of the comprehensive complication index (CCI) on predicting the overall survival (OS) of patients with ESCC following minimally invasive esophagectomy (MIE). METHODS This was a retrospective study of patients undergoing MIE for ESCC in the prone position between January 2011 and December 2018. Multivariate analyses using the Cox proportional hazards model were performed to determine independent risk factors for OS. RESULTS The study cohort included 229 patients who were categorized into patients with CCI values of ≥ 33.7 (CCI high) and < 33.7 (CCI low) by receiver-operating characteristic (ROC) curve analysis. There were no significant differences between the two groups according to clinicopathological factors, such as sex, age, tumor location, tumor depth, lymph node metastasis, and neoadjuvant chemotherapy. The intraoperative transfusion rate in the CCI high group was significantly higher than in the CCI low group. The 5 year OS rate was significantly lower in the CCI high group than in the CCI low group (49.5% vs. 65.7%, p = 0.030). By multivariate analyses, age, tumor depth, lymph node metastasis, and the CCI were independent predictors of OS. CONCLUSIONS Comprehensive assessment of postoperative complications using the CCI was useful in predicting OS of patients undergoing MIE for the ESCC.

Abstract
BACKGROUND Dissecting lymph nodes along the left recurrent laryngeal nerve (LRLN) is the most challenging step in thoracoscopic-assisted esophagectomy. To retract the proximal esophagus in the existing lymphadenectomy methods, either a special trocar is required to insert and take out endoscopic instruments or thoracic punctures are needed to externally retract the esophageal loop. Therefore, advanced skills for esophageal traction are important to facilitate the LRLN lymphadenectomy and to reduce the incidence of trauma to the chest wall. Herein, we present the magnetic anchoring and traction technique, a novel method for LRLN lymphadenectomy during thoracoscopic esophagectomy. METHODS The magnetic anchoring traction system was successfully used to retract the upper thoracic esophagus and to help expose the upper mediastinum in 10 cases of thoracoscopic-assisted esophagectomy. When the external magnet was moved outside of body, the internal magnet was coupled with a magnetic force to pull the proximal esophagus to the appropriate direction, which helped to expose the LRLN and adjacent lymph nodes. The lymph nodes adjacent to the LRLN could then be dissected completely without any damage to the nerve. RESULTS In all surgeries, the LRLN and adjacent lymph nodes were well visualized, and the number of trocars used to pass endoscopic instruments for retraction of the proximal esophagus or the number of thoracic punctures for external traction of the esophagus during the surgery were reduced. CONCLUSIONS In thoracoscopic-assisted esophagectomy, the magnetic anchoring and traction technique can improve the exposure of the LRLN, facilitate LRLN lymphadenectomy, and reduce chest wall trauma.

Abstract
BACKGROUND Esophagectomy with lymphadenectomy is the principal treatment for localized esophageal cancer. Conventional minimally invasive esophagectomy (C-MIE) in prone position has spread worldwide as it is less invasive. However, its efficacy remains controversial. Robot-assisted MIE (RAMIE) can have more advantages than C-MIE. Therefore, the current study aimed to validate whether RAMIE is associated with lower incidence of left recurrent laryngeal nerve (RLN) palsy compared with C-MIE in prone position. PATIENTS AND METHODS In total, 404 patients with esophageal carcinoma underwent MIE (353 C-MIEs and 51 RAMIEs) in prone position at Kobe University between 2010 and 2020. Then, propensity score matching was performed, and results showed that 51 patients should be included in each group. Thereafter, the perioperative outcomes between the two groups were compared. RESULTS The RAMIE group had a significantly longer operative time than the C-MIE group (P < 0.0001). However, the number of lymph nodes resected along the left RLN was similar in both groups. Moreover, the incidence of left RLN palsy was significantly lower in the RAMIE group than in the C-MIE [Clavien-Dindo classification grade II; 0 (0%) versus 32 (9%), P = 0.022 in entire cohort, and 0 (0%) versus 5 (10%), P = 0.022 in matched cohort. Esophagectomy Complications Consensus Group definitions type I; 8 (16%) versus 101 (29%), P = 0.041 in entire cohort and 8 (16%) versus 18 (35%) in matched cohort, P = 0.023]. CONCLUSION RAMIE is superior to C-MIE in prone position in decreasing the incidence of left RLN palsy.

Novel "Modified Bascule Method" for Lymphadenectomy Along the Left Recurrent Laryngeal Nerve During Robot-Assisted Minimally Invasive Esophagectomy. Ann Surg Oncol 2021; 28:4918-4927. [PMID: 33686596 DOI: 10.1245/s10434-021-09738-w] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Accepted: 12/30/2020] [Indexed: 11/18/2022]
Abstract
BACKGROUND Given the worldwide popularization of conventional minimally invasive esophagectomy (C-MIE), robot-assisted MIE (RAMIE) can be expected to provide a finer procedure. However, controversy remains regarding whether RAMIE is superior to C-MIE in preventing recurrent laryngeal nerve (RLN) palsy. Considering the shallow learning curve for RAMIE, a novel procedure for lymphadenectomy along the RLN during RAMIE is needed. METHODS Based on a logical and simple understanding of the left upper mediastinum anatomy, the authors developed a novel "modified bascule method" for RAMIE that could simplify lymphadenectomy along the left RLN and prevent it from being touched and stretched. Between 2018 and 2020, 46 patients with esophageal carcinoma underwent RAMIE using this method at Kobe University. RESULTS The modified bascule method was used to perform RAMIE for 29 men and 17 women with a median age of 67 years (range, 49-82 years). The median thoracoscopic procedure time was 438 min (range, 344-625 min), and the median console time was 351 min (range 273-518 min). The study harvested a median of 24 (range, 8-34) lymph nodes from the thoracic portion and 4 (range, 0-10) lymph nodes from along the left RLN. The mortality rate was 0%. Postoperative left RLN palsy classified as Clavien-Dindo (C-D) grade 1 or higher was observed for 9 patients (19%), whereas grade 2 or higher was not seen (0%). Pneumonia and anastomotic leakage rates higher than C-D grade 2 were respectively 13% and 19%. CONCLUSIONS The novel modified bascule method for RAMIE can promote feasible lymphadenectomy along the left RLN even when performed during the learning period.

Abstract
The incidence of recurrent laryngeal nerve palsy (RLNP) following minimally invasive esophagectomy has yet to be satisfactorily reduced. Use of intraoperative neuromonitoring (IONM), specifically of the RLN, during thyroidectomy has been reported to reduce the incidence of RLN injury. We now apply IONM during curative prone thoracoscopic esophagectomy, and we conducted a retrospective study to evaluate the feasibility and efficacy of intermittent monitoring of the RLN during the surgery. The study involved 32 consecutive patients who underwent esophagectomy with radical lymph node dissection for esophageal cancer. The patients were of two groups: an IONM group (n = 17) and a non-IONM group (n = 15). We chiefly strip around the esophagus preserving the membranous structure, which contains the tracheoesophageal artery, lymph nodes, and RLN. In the IONM group patients, we stimulated the RLN and measured the electromyography (EMG) amplitude after dissection, at the dissection starting point and dissection end point on both sides. For the purpose of the study, we compared outcomes between the two groups of patients. IONM was carried out successfully in all 17 patients in the IONM group. The incidence of RLNP was significantly reduced in this group. We found that both RLNs can be identified by mean of IONM easily, immediately, and safely and that the EMG amplitude attenuation rate is particularly useful for predicting RLNP.

Abstract
BACKGROUND Esophageal squamous cell cancer (ESCC) is one of the deadliest cancers in the world. Esophagectomy remains the principal treatment, and minimally invasive esophagectomy (MIE) has been performed worldwide. This study aimed to clarify whether the lymph node ratio (LNR), defined as the ratio of metastatic lymph nodes (LNs) to examined, is a prognostic factor for ESCC after MIE. METHODS This study included 327 MIEs with the patient in the prone position at two institutions from 2010 to 2015. Cox proportional hazards regression analyses using clinicopathologic characteristics and the LNR were performed for the pN1 patients and the whole cohort. RESULTS In the multivariate analysis for all stages, independent prognostic factors were depth of tumor invasion (P < 0.0001), LNR (P = 0.014), operative time (P = 0.003), and pneumonia (P = 0.012). In the analysis of the pN1 subgroup, the optimum LNR cutoff level for overall survival (OS) was 9 based on receiver operation characteristic analysis. The LNR was significantly associated with depth of tumor invasion (P = 0.004) and number of metastatic LNs (P < 0.0001). The OS curve for the group with an LNR of 9 or higher was significantly worse than for the group with an LNR lower than 9 (P < 0.001). Multivariate analyses demonstrated that the LNR is a unique independent prognostic factor for the pN1 subgroup (hazard ratio, 6.811; 95% confidence interval, 2.009-23.087; P = 0.002). CONCLUSIONS The LNR is an independent prognostic factor in ESCC after MIE. Especially for patients with pN1 status, the LNR is more useful than the number of metastatic LNs for predicting survival outcome.

Abstract
BACKGROUND Patients often experience severe weight loss after oesophagectomy. Enteral nutrition via a feeding jejunostomy tube (FT) is commonly practised. This study aimed to assess the effect of severe weight loss postoperatively and enteral nutrition via an FT on long-term prognosis after oesophagectomy. METHODS This study analysed 317 patients who underwent minimally invasive oesophagectomy at Kobe University Hospital and Hyogo Cancer Center from 2010 to 2015. The patients' body weight was evaluated at 3 months postoperatively. They were organised into the severe weight loss (n = 65) and moderate weight loss (n = 252) groups. Furthermore, they were categorised into the FT group (184 patients who had an FT placed during oesophagectomy) and no-FT group (133 patients without FT). Patients (119 per group) matched for the FT and no-FT groups were identified via propensity score matching. RESULTS The 5-year overall survival (OS) rate in the severe weight loss group was significantly lower (p = 0.024). In the multivariate analysis, tumour invasion depth (pT3-4), preoperative therapy and severe weight loss had a worse OS (hazard ratio = 1.89; 95% confidence interval = 1.12-3.17, hazard ratio = 2.11; 95% confidence interval = 1.25-3.54, hazard ratio = 1.82; 95% confidence interval = 1.02-3.524, respectively). No significant differences in the number of severe weight loss patients and OS were found between the FT and no-FT groups. CONCLUSION Severe weight loss is significantly associated with poor OS. In addition, enteral nutrition via an FT did not improve the severe weight loss and OS.

Abstract
PURPOSE Minimally invasive esophagectomy (MIE) has been increasingly used, but many reports have stated that recurrent laryngeal nerve (RLN) palsy after MIE is a major complication associated with postoperative pneumonia. Prevention of RLN palsy clearly has been a challenging task. The study aim was to determine if a three-dimensional (3-D) stereoscopic vision system can reduce the RLN palsy rate after MIE. METHODS This was a retrospective study of MIE (McKeown esophagectomy) using a 3-D or 2-D stereoscopic vision system to treat 358 patients in the prone position between April 2010 and March 2019. The patients who underwent 3-D MIE (3-D group) or 2-D MIE (2-D group) were matched by using propensity score matching. After matching, the perioperative outcomes were compared between the groups. RESULTS After propensity score matching, 154 patients were analyzed (77 patients, 3-D group; 77 patients, 2-D group). There were no significant differences in the patients' baseline characteristics in the matched cohort. There were no significant differences in the rates of pneumonia (Clavien-Dindo (C-D) grade ≥ II, 3-D vs. 2-D, 11 (14%) vs. 12 (16%)), anastomotic leakage (C-D grade ≥ II, 10 (13%) vs. 18 (23%)) and mortality. The rates of left RLN palsy (C-D grade ≥ IIIa, 1 (1.3%) vs. 7 (9.1%), P = 0.029), right RLN palsy (C-D grade ≥ I, 2 (3%) vs. 8 (10%), P = 0.049), comprehensive complication index (CCI®) (8.5 vs. 14.3, P = 0.011), and postoperative hospital stay period (median: 25 vs. 30 days, P = 0.034) were significantly lower in the 3-D group than in the 2-D group, respectively. CONCLUSIONS In MIE, the 3-D viewing system was one of the factors that reduced postoperative morbidities such as the rates of each RLN palsy and CCI®, leading to shorter postoperative hospital stay.

Abstract
Background We have recently standardized upper mediastinal lymph node dissection (UMLND) using a microanatomy-based concept in thoracoscopic esophagectomy in the prone position (TEPP), and introduced robot-assisted minimally invasive esophagectomy (RAMIE) using the same concept as in TEPP while aiming at solo surgery. The purpose of this study was to investigate the outcomes of RAMIE using the microanatomy-based concept in the initial introduction phase. Methods We have performed more than 500 TEPP procedures as minimally invasive esophagectomy (MIE). After performing about 400 cases of MIE, we established a microanatomy-based standardization of UMLND. In October 2018, we introduced RAMIE, and have performed 75 procedures in 20 months. Two groups were analyzed: a group after microanatomy-based standardization in TEPP (100 cases after completing 400 cases of TEPP) and a RAMIE group (75 cases). Finally, 51 paired cases were matched using a propensity score. Furthermore, the change in postoperative short-term outcome for RAMIE in the initial introduction phase was analyzed. Results Although there were no significant differences between the two groups in the number of upper mediastinal lymph nodes dissected, there was a significant decrease (P = 0.036) in intraoperative blood loss volume with RAMIE, representing a definite benefit for patients. The thoracoscopic operative time for RAMIE decreased by almost 100 min following less than 50 cases of experience, reaching the same level as that for recent TEPP, but with only one-tenth the operator experience. There were no significant differences in the total postoperative morbidity rate including the recurrent laryngeal nerve palsy rate. Conclusion RAMIE has been introduced safely and smoothly using the microanatomy-based concept established in TEPP.

Abstract
BACKGROUND In esophageal squamous carcinoma, lymphadenectomy along the left recurrent laryngeal nerve (RLN) is recommended owing to its highly metastatic potential. However, this procedure is difficult due to limited working space in the left upper mediastinum, and increases postoperative complications.
AIM To present a novel method for lymphadenectomy along the left RLN during thoracoscopic esophagectomy in the semi-prone position.
METHODS The fundamental concept of this novel method is to exfoliate a bilateral pedicled nerve flap, which is a two-dimensional membrane, which includes the left RLN, lymph nodes (LNs) along the left RLN, and tracheoesophageal vessels, by suspending the esophagus to the dorsal side and pushing the trachea to the ventral side (named “bilateral exposure method”). Then, the hollow-out method is performed to transform the two-dimensional membrane to a three-dimensional structure, in which the left RLN and tracheoesophageal vessels are easily distinguished and preserved during lymphadenectomy along the left RLN. This novel method was retrospectively evaluated in 116 consecutive patients with esophageal squamous carcinoma from August 2016 to February 2018.
RESULTS There were 58 patients in each group. No significant difference was found between the two groups in terms of age, gender, postoperative pneumonia, anastomotic fistula, and postoperative hospitalization. However, the number of dissected LNs along the left RLN in this novel method was significantly higher than that in the conventional method (4.17 ± 0.359 vs 2.93 ± 0.463, P = 0.0447). Moreover, the operative time and the rate of postoperative hoarseness in the novel method were significantly lower than those in the conventional method (306.0 ± 6.774 vs 335.2 ± 7.750, P = 0.0054; 4/58 vs 12/58, P = 0.0312).
CONCLUSION This novel method for lymphadenectomy along the left RLN during thoracoscopic esophagectomy in the semi-prone position is much safer and more effective.

Abstract
INTRODUCTION The quality of left recurrent laryngeal nerve lymph node dissection is critical in esophageal cancer. We investigated whether esophageal wire traction in three-hole thoracoscopic esophagectomy can improve the same. MATERIAL AND METHODS We retrospectively analyzed the data of 98 patients who underwent thoracoscopic esophagectomy in our center from January 2018 to July 2018: 36 patients with esophageal wire traction and 62 patients without traction (control group). The clearance time for left recurrent laryngeal nerve lymph nodes, thoracic bleeding volume, number of left recurrent laryngeal nerve lymph nodes, and complications were recorded. RESULTS The observation group had a shorter clearance time for the left recurrent laryngeal nerve lymph nodes (15.8 ± 6.9 min vs. 20.00 ± 6.2 min), less thoracic bleeding (55.8 ± 30.2 mL vs. 70.7 ± 30.3 mL), and higher number of dissected left recurrent laryngeal lymph nodes (3.3 ± 1.4 vs. 2.5 ± 1.1) than the control group. There was no significant difference in the incidence of anastomotic leakage, pulmonary infection, arrhythmia, chylothorax, and nerve injury. CONCLUSIONS Esophageal wire traction shortens the clearance time for the left recurrent laryngeal nerve lymph nodes, reduces thoracic bleeding, and improves the quality of left recurrent laryngeal nerve lymph node dissection in three-hole thoracoscopic esophagectomy.

Abstract
BACKGROUND During the past decade, minimally invasive esophagectomy (MIE) for esophageal cancer has been adopted worldwide with expectations of lower invasiveness. However, the rate of postoperative pneumonia, which is an independent risk factor for oncological prognosis in esophageal cancer, remains high. The aim of this retrospective follow-up study is to clarify whether there is a strong correlation between recurrent laryngeal nerve (RLN) palsy and postoperative pneumonia in MIE. METHODS This retrospective follow-up study included 209 patients with esophageal cancer who underwent thoracoscopic esophagectomy in the prone position (TEP) at Kobe University between 2011 and 2018. Inclusion criteria included age 18-85 years; cT1-3, cN0-3 disease; upper mediastinal lymphadenectomy; and ability to undergo simultaneous esophagectomy and reconstruction of the gastric conduit or pedicled jejunum. Univariate and multivariate logistic regression were conducted to identify independent risk factors for pneumonia. RESULTS Among 209 TEPs, pneumonia of Clavien-Dindo classification grade > II occurred in 44 patients (21%). In the pneumonia positive and negative groups, there were significant differences in age (67.9 ± 7.5 vs. 64.9 ± 8.6 years), 3-field lymph node dissection [27 (61%) vs. 67 (41%)], transfusion [20 (45%) vs. 41 (25%)], left RLN palsy [19 (43%) vs. 18 (11%)], and any RLN palsy [20 (45%) vs. 18 (11%)]. In multivariate analysis, any RLN palsy was associated with a higher incidence of pneumonia [odds ratio (OR), 6.210; 95% confidence interval (CI), 2.728-14.480; P < 0.0001]. In addition, age was associated with a higher incidence of pneumonia (OR, 1.049; 95% CI, 1.001-1.103; P = 0.046). Changes in the rate of any RLN palsy over time were quite similar to changes in the incidence of pneumonia. CONCLUSION There is a strong correlation between RLN palsy and pneumonia in MIE for esophageal cancer. Prevention of RLN palsy may reduce the incidence of pneumonia, leading to better oncological prognosis.

Abstract
BACKGROUND Although thoracoscopic esophagectomy in the prone position (TEPP) has become a standard procedure for esophageal cancer surgery, upper mediastinal lymph node dissection (UMLND) on the left side remains an issue. We have recently developed a new standardized approach to left UMLND in TEPP based on the microanatomy of the membranes and layers with the aim of achieving quick and safe surgery. The purpose of this study was to establish and evaluate our new standardized procedure in left UMLND. PATIENTS AND METHODS Patients were divided into 2 groups: a pre-standardization group (n = 100) and a post-standardization group (n = 100). Eventually, 83 paired cases were matched using propensity score matching. In our new standardized procedure, left UMLND was performed while focusing on the visceral sheath, vascular sheath, and the fusion layer between them using a magnified view. RESULTS The thoracoscopic operative time was significantly shorter (P < 0.001) in the post-standardization group [n = 83; 209.0 (176.0-235.0) min] than in the pre-standardization group [n = 83; 235.5 (202.8-264.5) min]. No significant differences were found in the number of mediastinal lymph nodes dissected or intraoperative blood loss between the two groups. There was a tendency for the total postoperative morbidity to decrease in the post-standardization group. Furthermore, the left recurrent laryngeal nerve palsy rate was significantly lower in the post-standardization group (18.1% to 8.7%, P = 0.015). CONCLUSION Microanatomy-based standardization contributes to safe and efficient left UMLND.

Abstract
INTRODUCTION Recurrent laryngeal nerve (RLN) paralysis is a major complication of esophageal cancer surgery. The free jaw clip (FJ clip) was developed as an organ-retracting device, and it can also reduce the number of ports required during surgery. Here, we describe a new technique for lymphadenectomy along the left RLN using the FJ clip. MATERIALS AND SURGICAL TECHNIQUE After the middle and lower mediastinal lymph nodes were dissected, the upper esophagus and other tissues, including the lymph nodes and left RLN, were retracted by cutting the tracheal arteries between the esophagus and trachea and then pulling the upper esophagus to the dorsal side with the FJ clip. The esophagus was transected at the upper mediastinum, and the proximal esophagus was drawn by the FJ clip. This technique helped provide a good field of view during lymphadenectomy along the left RLN. The data of nine consecutive patients who underwent video-assisted esophagectomy in the left lateral decubitus position by the same surgeon were reviewed. Postoperative left RLN paralysis occurred in only one patient in whom the RLN could not be preserved. DISCUSSION Given the excellent short-term outcomes with respect to left RLN paralysis, lymphadenectomy along the left RLN using the FJ clip was safe and feasible.

Abstract
Background The objective of this study was to compare three kinds of lymphadenectomy methods along the recurrent laryngeal nerve (RLN) and assess the safety and effectiveness of the new method. Methods A total of 194 patients with esophageal cancer who underwent minimally invasive esophagectomy (MIE) at our institution from May 2013 to May 2017 were analyzed retrospectively. According to the method of lymphadenectomy along the left RLN, the patients were divided into three groups: 75 cases underwent the conventional method (A group), 80 cases the skeletonized method (B group) and 39 cases the modified Bascule method (C group). The number of dissected lymph nodes and surgical outcomes were recorded and compared to identify differences among the three groups. Results The frequency of metastasis to the LRLN lymph node was 18.6% among all patients, and 12%, 20% and 28% in groups A, B and C, respectively. The number of harvested lymph nodes (total/chest/LRLN/LRLN+) in group B and group C were significantly greater than that of group A, but not significant between group B and group C. The hoarseness rate in group C was 15.4%, which was lower than the rate in group B (21.3%) and higher than the rate in group A (13.3%), but there was no statistical significance. Conclusions The new method for lymphadenectomy along the left RLN during MIE in the semi‐prone position is safe and reliable. It provides sufficient lymph node dissection along the left RLN.

Abstract
In order to perform the total mediastinal lymphadenectomy during minimally invasive esophageal resection, doing the lymphadenectomy along the left recurrent laryngeal nerve (LRLN) may be a difficult part of this intervention. One reason is the need for the correct visualization of the area; another is not wanting to compromise the integrity of the nerve. In this review article the different modalities for approaching this upper mediastinal area by thoracoscopy are described.

Abstract
Based in the anatomical concept of the mesoesophagus, that at subcarinal level all the vessels come through a by-layer connective tissue plane from the aorta to the esophagus whereas supracarinally these structures will come from both sides, with vagal and recurrent laryngeal nerves, a minimally invasive mesoesophageal (MIME) resection model may be described. Based on this surgical plane concept, dissection of esophagus and mediastinal lymphadenectomy can be performed along these structures establishing clear anatomical modules for an adequate oncological resection.

Abstract
BACKGROUND Because the thoracic esophageal carcinoma has a high metastatic rate to the upper mediastinal lymph nodes, especially along the recurrent laryngeal nerves (RLN), it is crucial to perform a complete lymphadenectomy along the RLN without complications. Although intraoperative neural monitoring (IONM) during thyroid surgery has gained widespread acceptance as a useful tool for visual nerve identification, utilization of IONM during esophageal surgery has not become common. Here, we describe our procedures, focusing on a lymphadenectomy along the RLN utilizing the IONM. METHODS Eighty-seven patients who underwent prone esophagectomy between December 2009 and September 2017 were included in this study. We divided patients into two groups: neural monitoring group (Nm, n = 31) and conventional method group without IONM (Cm, n = 56). We first dissect around the esophagus, preserving the membranous structure; mesoesophagus, which contains tracheoesophageal artery; RLN; and lymph nodes (mesenterization). In Nm group, we next identify the location of the RLN, which runs in the mesoesophagus using IONM before visual contact. Next, we perform lymphadenectomy around the RLN, preserving the nerve itself. Early surgical outcomes were retrospectively compared between two groups. RESULTS In all 31 cases in the Nm group, we detected the location of the RLN before the visual contact. The sensitivity and specificity of the IONM to detect the RLN paralysis were 67% and 96%, respectively. Postoperative RLN paralysis was observed in 3 cases in the Nm group (9.7%), which was lower than that in the Cm group (32.1%, p = 0.03). Clavien-Dindo grade 2 and over aspiration were seen in 2 (Nm, 6.5%) and 16 (Cm, 28.6%) cases (p = 0.01), respectively. The postoperative hospital stay was shorter in the Nm group (22 days, median) than in the Cm group (39 days, median, p = 0.0002). The number of dissected mediastinal lymph nodes was similar in both groups (25 vs. 20, median, p = 0.12). CONCLUSIONS The combination of IONM and the concept of the mesoesophagus have substantial advantages in allowing accurate and safe mediastinal lymphadenectomy during prone esophagectomy.

Mesenteric excision for esophageal cancer surgery: based on the concept of mesotracheoesophagus. Int Cancer Conf J 2018; 7:117-120. [PMID: 31149528 DOI: 10.1007/s13691-018-0329-y] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2018] [Accepted: 05/07/2018] [Indexed: 10/16/2022] Open
Abstract
The fundamental principle of surgery for intestinal cancer is mesenteric excision. It has been widely accepted as radical surgery for colorectal cancer, and it comprises procedures such as complete mesocolic excision for colon cancer and total mesorectal excision for rectal cancer. So far, the concept of mesenteric excision of the esophagus has not been well documented, but our surgical experience with a magnified view using a thoracoscope and understanding of the surgical anatomy based on embryologic foregut development has led us to introduce the concept of mesotracheoesophagus. Using this concept, our technique is reproducible, effective, and safe for lymph node dissection along the left recurrent laryngeal nerve. Here we report our concept, procedure, and results of thoracoscopic esophageal cancer surgery.

Abstract
PURPOSE Esophageal cancer is one of the deadliest cancers worldwide. Esophagectomy with lymphadenectomy is regarded as the only curative option for resectable esophageal cancer, but it is associated with high morbidity and mortality. Multidisciplinary team (MDT) management was recently associated with improved outcomes after surgery for esophageal cancer. The aim of this study was to investigate the effect of standardizing procedures for minimally invasive esophagectomy (MIE) in the MDT setting. METHODS This was a case-matched control study of 154 patients with esophageal cancer who underwent thoracoscopic esophagectomy in the prone position (TEP) between 2012 and 2016. Surgery was performed by two attending surgeons (surgeons A and B) who began working together in the same MDT in 2015. At that time, the following surgical procedures were standardized between surgeons A and B: mediastinal lymphadenectomy, abdominal procedures, and estimation of the blood supply of the gastric conduit. Short-term outcomes were compared between the following paired groups using propensity scores: surgeon A's pre- and post-standardization groups, surgeon B's pre- and post-standardization groups, and surgeon A's post-standardization group and surgeon B's post-standardization group. RESULTS Concerning surgeon A, the estimated total blood loss in the post-standardization group (142 ± 87 mL) was significantly lower than that in the pre-standardization group (376 ± 215 mL, P = 0.006). The rate of left recurrent laryngeal nerve palsy in the post-standardization group (13%) was significantly lower than that in the pre-standardization group (47%, P = 0.046). Concerning surgeon B, the rate of anastomotic leakage in the post-standardization group (0%) was significantly lower than that in the pre-standardization group (11%, P = 0.039). Comparing the post-standardization groups of surgeons A and B, there were no significant differences in operative outcomes or morbidity. CONCLUSIONS Standardizing procedures for MIE improved and homogenized surgical short-term outcomes.

Abstract
BACKGROUND A clear operative view of the middle and lower mediastinum is possible in prone position during video-assisted thorocoscopic surgery of esophagus (VATS-E), but the working space in the upper mediastinum is limited and lymph node dissection along the left recurrent laryngeal nerve (RLN) is difficult in this position. METHODS Esophagectomy and lymph node dissection are performed for pneumothorax by maintaining CO2 insufflation in the prone position. Working space in the left upper mediastinal area for lymph node dissection around RLN is limited in this position. To create space, the residual esophagus is stripped in the reverse direction and retracted toward the neck after the stomach tube is removed through the nose. Lymph node dissection is performed after stripping the residual esophagus. RESULTS We could obtain a clear operative field in the upper left mediastinum by stripping the residual esophagus in the prone position, enabling safe and straightforward lymph node dissection along the left RLN. The rate of permanent RLN paralysis was 1.2%. CONCLUSIONS Lymph node dissection along the left RLN after esophageal stripping is possible in the prone position during VATS-E.

A new method (the "Pincers maneuver") for lymphadenectomy along the right recurrent laryngeal nerve during thoracoscopic esophagectomy in the prone position for esophageal cancer. Surg Endosc 2016; 31:1496-1504. [PMID: 27492431 DOI: 10.1007/s00464-016-5124-2] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2016] [Accepted: 07/13/2016] [Indexed: 12/16/2022]
Abstract
BACKGROUND In esophageal squamous cell carcinoma, the number of dissected lymph nodes (LNs), including those along the recurrent laryngeal nerves (RLNs), influences prognosis and nodal staging accuracy. However, dissection of LNs along the RLN increases the risk of complications, especially RLN palsy. Therefore, complete dissection of these LNs with prevention of RLN palsy is recommended. We present herein a new method for lymphadenectomy along the right RLN, named the Pincers maneuver, during thoracoscopic esophagectomy in the prone position (TEP). METHODS The fundamental concept in this new method is to first exfoliate the two-dimensional membrane (lateral pedicle), which includes the right RLN, LNs along the right RLN, and the primary esophageal artery, from the right side of the trachea toward the neck. Using a Pincers strategy, closing in from the inner and outer sides of the two-dimensional membrane (lateral pedicle), lymphadenectomy along the right RLN toward the right inferior thyroid artery should be easy. This technique was evaluated in 30 consecutive cases of TEP for squamous cell cancer. RESULTS There were 15 patients who underwent the new method (Pincers maneuver; Pm) and 15 patients who underwent the conventional method (Cm). There were no significant differences between the two groups in the duration of the thoracic procedure and dissection along the right RLN. No intraoperative and postoperative morbidity related to the right RLN was observed in either group. The Pm group had a higher number of dissected LNs along the right RLN than the Cm group (6.3 vs 3.1, p = 0.044). CONCLUSIONS The Pincers maneuver for lymphadenectomy along the right RLN during TEP is technically safe and feasible. It increases the number of dissected LNs along the right RLN.

Abstract
BACKGROUND Due to limited space in the left upper mediastinum, complete dissection of lymph nodes (LN) along left recurrent laryngeal nerve (RLN) is difficult. We herein present a novel method for lymphadenectomy along the left RLN during thoracoscopic esophagectomy in the semi-prone position for esophageal carcinoma. The method, suspension the esophagus and push aside trachea, allows en bloc lymphadenectomy along the left RLN from the below aortic arch to the thoracic inlet. METHODS Between September 2014 and September 2015, a total of 110 consecutive patients with esophageal carcinoma were treated with thoraco-laparoscopic esophagectomy with cervical anastomosis in the semi-prone position. Outcomes between those who received surgery with the novel method and conventional surgery were compared. RESULTS Fifty patients underwent the novel method and sixty received conventional surgery. The operative field around the left RLN was easier to explore with the novel method. The estimated blood loss was less (23.7±8.2 vs. 34.2±10.3 g, P=0.001), and the number of harvested LNs along the left RLN was greater (6.4±3.2 vs. 4.1±2.8 min, P=0.028) in the novel method group, while the duration of lymphadenectomy along left RLN was longer in the novel method group (28.2±3.9 vs. 20.3±2.8 min, P=0.005). The rate of hoarseness in the novel and conventional groups was 10% and 16.7%, respectively. No significant difference in postoperative morbidity related to the left RLN was noted between the groups. CONCLUSIONS The novel method during semi-prone esophagectomy for esophageal carcinoma is associated with better surgeon ergonomics and operative exposure.
