Abstract Background The rates of thoracoscopic esophagectomy performed in the prone and left lateral decubitus positions are similar in Japan. We retrospectively reviewed short term outcomes of thoracoscopic esophagectomy for esophageal cancer performed in the left lateral decubitus position under artificial pneumothorax by CO2 insufflation in a single institution. This study aimed to evaluate the feasibility of applying this procedure. Methods Between July 2013 and March 2017, 83 patients with esophageal cancer underwent thoracoscopic esophagectomy in the left lateral decubitus position under artificial pneumothorax by CO2 insufflation. The thoracic procedure is performed as follows: The lymph nodes around the right recurrent laryngeal nerve are dissected. On the cranial side, the lymph node dissection is advanced to the level of the inferior thyroid artery. Then, the assistant rotates the trachea toward the ventral side, and the lymph nodes around the left recurrent laryngeal nerve are dissected. The middle and inferior mediastinal lymph nodes are dissected including supradiaphragmatic lymph nodes and the dorsal lymph nodes around the thoracic descending aorta. Then, the esophagus is transected using an automatic suture device. Finally, the tracheal bifurcation area lymph nodes are dissected. We retrospectively analyzed these patients. Results The completion rate of thoracoscopic esophagectomy was 94.0%, and the procedure was converted to thoracotomy in five patients, due to hemorrhage, severe adhesion. The mean intrathoracic operative time, intrathoracic blood loss, and number of dissected mediastinal lymph nodes were 220.0 min, 130.1 mL, and 22.0, respectively. Postoperative complications included pneumonia (8.4%), anastomotic leakage (16.9%), and recurrent nerve paralysis (8.4%). Postoperative (30d) mortality was 1/83 (1.2%) due to ARDS. Conclusion Standardization of the procedure for thoracoscopic esophagectomy in the left lateral decubitus position under artificial pneumothorax by CO2 insufflation, with a standardized clinical pathway for perioperative care led to favorable surgical outcomes.

Abstract   Standardized thoracoscopic esophagectomy for thoracic esophageal carcinoma in the left lateral decubitus position under artificial pneumothorax is slightly more difficult to dissect the middle and lower mediastinum than in prone position, but it is possible to operate the upper mediastinum with good visual field. In salvage surgery after definitive chemoradiotherapy, it is difficult to complete the operation only by throscopic surgery, and it is thought that sometimes small thoracotomy can be performed safely and reliably. Methods If this procedure is considered feasible, start with thoracoscopic surgery. If it is decided that the procedure cannot be completed, add a small thoracotomy of about 10–15 cm to allow one hand. Thoracoscopy not only reduced invasiveness, shared detailed anatomy, but also improved operability by taping the esophagus and ensured emergency safety. Results This standardized procedure is applied to salvage surgery after definitive chemoradiotherapy from January 2016 to March 2019. Thoracoscopic surgery was performed in 14 of the 27 cases (52%). Thoracoscopic surgery was completed in 10 cases and small thoracotomy was used in 4 cases. There are no serious complications such as bleeding. Conclusion Starting surgery with a thoracoscopy and adding small thoracotomy as appropriate can share the advantages of thoracotomy and throcoscopic surgery. This technique has the advantage that it can be easily converted to thoracotomy even in an emergency, and is considered to be superior to advanced cancer.

Abstract Description Because esophagectomy with radical lymphadenectomy is highly invasive, thoracoscopic esophagectomy (TE) is attracting attention as a less invasive procedure. We first performed TE with the left decubitus position in 1996. In 2009 we developed a hybrid of the prone and left lateral decubitus positions for TE, and a total of 420 patients underwent TE with a hybrid position. We introduced TE with a hybrid position for the following three reasons: (1) Mobilization and lymphadenectomy around the middle and lower esophagus are easier in the prone position. Thanks to artificial pneumothorax and the gravity, the middle and lower mediastinum are opened, and which give us good surgical field. (2) Lymphadenectomy along the left recurrent laryngeal nerve (RLN) is more reliable and precise when performed in the left lateral decubitus position. We can dissect lymph node around the RLN higher position in the upper mediastinum. (3) Unexpected events requiring conversion to thoracotomy (e.g. massive bleeding, injury of other organs, dense intrathoracic adhesion, resection of adjacent organs) are easier to deal with in the left lateral decubitus position. The patient is fixed on the operating table with the semi-prone position and we can easily change patient positions from the left lateral decubitus position to the prone position and vice versa using rotation system of the operation table. The upper mediastinal procedure including lymphadenectomy along the right and left RLN is performed with the patient in the left lateral decubitus position, while the middle and lower mediastinal procedures are performed with the patient in the prone position with artificial pneumothorax (7mmHg). The abdominal procedures have beenwere performed by hand-assisted laparoscopic surgery (HALS) and gastric tube reconstruction in thethrough a posterior mediastinal route was performed as s a standard surgical procedure in our institution. The magnifying effect of thoracoscope enables us to perform more precise surgery and preserve nerve and vessels, and a hybrid position is thought to be feasible and effective methods.

Abstract Background We initially performed minimally invasive esophagectomy in a left lateral decubitus position through 5 ports in 1996, and we have now treated over 900 cases using this approach. This position has many benefits, but it also has some drawbacks. We were able to operate with good results after we introduced artificial pneumothorax with CO2 insufflation in 2010. We investigated the short- and long-term outcomes of thoracoscopic surgery for esophageal cancer in the left lateral decubitus position at our institution. Methods From 1996 to 2016, 807 esophageal cancer patients were treated with minimally invasive esophagectomy in the left lateral decubitus position at our hospital. We compared the 289 cases treated in the early period (1996–2005) and 518 cases treated in the late period (2006–2016), in which the procedure was standardized and operator training was established Results The completion rate of thoracoscopic surgery was 99.5%, with the procedure switched to thoracotomy in only 3 patients in whom hemorrhage occurred. The mean intrathoracic operative time was 205.0 min, mean intrathoracic blood loss was 127.3 mL, and mean number of dissected mediastinal lymph nodes was 24.7. The postoperative complications were pneumonia (8.5%), anastomotic leakage (7.5%), and recurrent nerve paralysis (7.8%). The 5-year overall survival rate was 69.5%. Comparison of 289 cases treated in the early period (1996–2005) and 518 cases treated in the late period (2006–2016), revealed significant differences in mean intrathoracic blood loss (174.0 vs. 94.2 mL); number of dissected mediastinal lymph nodes (20.0 vs. 28.4); postoperative hospital stay (33.4 vs. 20.0 days, all P < 0.001); and postoperative anastomotic leakage (13.9% vs. 1.6%, P < 0.0001). In recent operation, we do not have recurrent laryngeal nerve paralysis and hoarseness after we take care of the micro anatomical layer, stretch and thermal damage of recurrent laryngeal nerve when we dissect the lymph node. Conclusion These data indicate significant improvements in intrathoracic blood loss, number of dissected mediastinal lymph nodes, anastomotic leakage, and postoperative hospital stay, reflecting continued improvement of minimally invasive esophagectomy performed in the left lateral decubitus position at our institution.

Objective: We reviewed the surgical outcomes of minimally invasive esophagectomy (MIE), especially the number of lymph nodes retrieved, for the patients with esophageal cancer to clarify the surgical benefits of MIE in patients with esophageal cancer. Material and Methods: A systematic literature search was performed, and articles that fully described the surgical results of MIE were selected. Parameters such as operative time, blood loss, the number of lymph nodes retrieved, and postoperative complications were compared among patients undergoing minimally invasive esophagectomy (MIE) in the left lateral decubitus position (MIE-LP), MIE in the prone position (MIE-PP), and open thoracic esophagectomy (OE). Results: The conversion rate from MIE to OE was very low. MIE-PP was associated with lower blood loss than OE and MIE-LP. Results of a multicenter randomized controlled trial demonstrated that pneumonia and recurrent laryngeal nerve paralysis in MIE-PP significantly reduced compared with OE. Although postoperative complications were not different between MIE-PP and MIE-LP, the number of lymph nodes retrieved in MIE-PP was higher than that in MIE-LP. Conclusion: MIE-PP has potential benefits in terms of less surgical invasiveness and improvement of mediastinal lymph node dissection. A prospective randomized control trial using a large number of cases and long-term follow-up is recommended for analyses of appropriate mediastinal lymph node dissection and its impact on oncological benefit.

Abstract Background While thoracoscopic esophagectomy is a widely performed surgical procedure, only few studies regarding the influence of body position on changes in circulation and breathing, after the surgery, have been reported. This study aimed at evaluating the effect of body position, during surgery, on the postoperative breathing functions of the chest. Methods A total of 266 patients who underwent right-sided transthoracic esophagectomy for esophageal cancer from 2004 to 2012 were included in this study. Fifty-four of them underwent open thoracotomies in the left lateral decubitus position (Group O), 108 underwent thoracoscopic esophagectomy in the left lateral decubitus position (Group L) and 104 patients were treated by thoracoscopic esophagectomy in the prone position (Group P). Two patients in Group P, who presented with intra-operative bleeding and underwent thoracotomy, were subsequently excluded from the pulmonary function analysis. Results Two patients in Group P had to be changed from the prone position to the lateral decubitus position and underwent thoracotomy in order to control intra-operative bleeding. Despite the significantly longer chest operation period in Group P, total blood loss was significantly lower in this group when compared to Groups O and L. Furthermore, patients in Group P presented with significantly lower water balance during the perioperative period and markedly higher SpO2/FiO2 ratio after the surgery. The incidence of respiratory complications was significantly higher in Group O when compared to the other two groups; however, no significant differences were observed between the Groups L and P. Conclusion From a surgical point of view, artificial pneumothorax and gravity improves the operative field view in the prone position without any compression of the right lung, thereby resulting in no mechanical damage to the lungs. Prone position esophagectomy is a useful surgical technique, which appears to preserve the postoperative pulmonary function. The patients are able to endure the surgical procedure and present with less respiratory complications. Disclosure All authors have declared no conflicts of interest.

Abstract   Thoracoscopic esophagectomy (TE) is becoming a common surgical method for esophageal cancer. TE is performed with the patient the left lateral decubitus position, prone position, or hybrid position combining the left lateral decubitus and prone positions. However, only few studies have compared the clinical utility of these TE positions. Methods In our institute, we introduced TE in the prone position (prone TE) in 2014, and have performed TE in the hybrid position (hybrid TE) since March 2017. The present study compared the short-term outcomes of prone TE versus hybrid TE. One-hundred-and-three patients with esophageal or esophagogastric junction cancer who underwent TE between March 2014 and December 2019 were included. Patients were divided into those who underwent prone TE (prone TE group; n = 43) and those who underwent hybrid TE (hybrid TE group; n = 60). Clinicopathological data were retrospectively reviewed and compared between groups. Results There were no differences between groups in age, tumor histology, and tumor location. Compared with the hybrid TE group, the prone TE group had a smaller tumor depth (P &lt; 0.001), lower grade of lymph node metastasis (P = 0.003), and less severe tumor stage (P = 0.001). The operation time for the thoracoscopic procedure was shorter in the hybrid TE group (318.9 vs 249.2 min, P = 0.002). The rate of recurrent laryngeal nerve paralysis (Clavien-Dindo grade I–III) was significantly lower in the hybrid TE group (41.9% vs 11.7%, P &lt; 0.001), whereas there were no differences between groups in the rates of anastomotic leakage, atelectasis, or pneumonia. Conclusion The most significant differences between prone TE and hybrid TE involved the upper mediastinal procedures. In hybrid TE, the motion of the assistant’s forceps causes less interference with the operative field, and the angle at which the operator's forceps approach the upper mediastinal lymph nodes enables the maintenance of appropriate traction. These advantages of hybrid TE appeared to result in a shorter operation time and less recurrent laryngeal nerve paralysis compared with prone TE.
