Background: Esophagectomy is performed in all patients with resectable esophageal cancer. Transthoracic-Laparoscopic Esophagectomy (TLE) is a minimally invasive method and considered to be the most appropriate method. In this study, we aim to evaluate and compare the perioperative outcome, and 1-year overall survival of TLE and Transhiatal Esophagectomy (THE) approaches. Methods: In this retrospective study, we reviewed the medical records of 108 patients with esophageal cancer undergoing TLE (n=44) or THE (n=64) between 2015 and 2018. The patients were followed for one year. The intraoperative and postoperative findings, as well as 1-year overall-survival, were compared between the two groups. Results: TLE compared to THE had a longer surgery duration (278.63±33.28 vs 223.28±33.99 min, P=0.001), a higher number of dissected lymph nodes (15.06±2.95 vs 10.21±2.58, P=0.001), less blood loss (345.45±178.76 vs 585.15±294.75 mL, P<0.001), and need for transfusion (20.5% vs 45.3%, P=0.006) during surgery as well as lower ICU stay (2.59±0.77 vs 3.90±0.83 days, P<0.001) and ward stay (8.77±0.96 vs 11.42±1.71 days, P<0.001). THE had somewhat higher complication than TLE, but with no significant differences. Conclusion: TLE had a similar rate of complication to THE approach, but with lower blood loss and lower ICU and hospital stay, it is a more appropriate method for esophagectomy.

Transthoracic esophagectomy (TTE) is believed to have advantages for mediastinal lymphadenectomy in the treatment of resectable esophageal cancer despite its association with a greater incidence of pulmonary complications and postoperative mortality. Transhiatal esophagectomy is regarded as less invasive, though insufficient in terms of lymph node dissection. With the aim of achieving lymph dissection equivalent to that of TTE, we have developed a nontransthoracic esophagectomy (NTTE) procedure combining a video-assisted cervical approach for the upper mediastinum and a robot-assisted transhiatal approach for the middle and lower mediastinum. We prospectively studied 22 accumulated cases of NTTE and verified feasibility by analyzing perioperative and histopathological outcomes. We compared this group's short-term outcomes with outcomes of 139 equivalent esophageal cancer cases operated on at our institution by conventional TTE (TTE group). In the NTTE group, there were no proced...

Background: There is a rise in incidence of esophageal carcinoma due to increasing incidence of adenocarcinoma. Probably the only curative option to date is the use of neoadjuvant therapy followed by surgical resection. Traditional open esophageal resection is associated with a high morbidity and mortality rate. Furthermore, this approach involves long intensive care unit stay, in-hospital stay and long recovery period. Minimally invasive esophagectomy could reduce the morbidity and accelerate the post-operative recovery. Methods/Design: Comparison between traditional open and minimally invasive esophagectomy in a multi-center, randomized trial. Patients with a resectable intrathoracic esophageal carcinoma, including the gastro-esophageal junction tumors (Siewert I) are eligible for inclusion. Prior thoracic surgery and cervical esophageal carcinoma are indications for exclusion. The surgical technique involves a right thoracotomy with lung blockade and laparotomy either with a cervical or thoracic anastomosis for the traditional group. The minimally invasive procedure involves a right thoracoscopy in prone position with a single lumen tube and laparoscopy either with a cervical or thoracic anastomosis. All patients in both groups will undergo identical pre-operative and post-operative protocol. Primary endpoint of this study are post-operative respiratory complications within the first two post-operative weeks confirmed by clinical, radiological and sputum culture data. Secondary endpoints are the operative data, the postoperative data and oncological data such as quality of the specimen and survival. Operative data include duration of the operation, blood loss and conversion to open procedure. Post-operative data include morbidity (major and minor), quality of life tests and hospital stay. Based on current literature and the experience of all participating centers, an incidence of pulmonary complications for 57% in the traditional arm and 29% in the minimally invasive arm, it is estimated that per arm 48 patients are needed. This is based on a two-sided significance level (alpha) of 0.05 and a power of 0.80. Knowing that approximately 20% of the patients will be excluded, we will randomize 60 patients per arm.
State-of-the-art of Esophagectomy for Cancer: From Open to Laparoscopic and Robotic Technique
Open Access Macedonian Journal of Medical Sciences, 2020
INTRODUCTION: The results for the meta-analytical review, which contrasted laparoscopic or robotically assisted esophagectomy for cancer against open esophagectomy (OE), indicated feasibility and safety associated with the robotic method. AIM: The objective of this study is to review the current literature on MIE (Laparo-thoracoscopic and Robotic approach) and open approach and check the state-of-the-art of esophagectomy for cancer. MATERIALS AND METHODS: The comparison of studies which contrasted laparoscopic or robotically assisted esophagectomy for cancer against open esophagectomy (OE). RESULTS: This review represented the largest sequence of mini-invasive esophagectomy (MIE) to date and the results appear to be comparable to those attained by the traditional open approach. MIE constitutes a safe procedure with a learning curve of around 36 cases. CONCLUSION: The studies did not reveal variations in mortality and morbidity rate, conversion rate, intensive care unitstay, 1-month ...

The main treatment modality for esophageal cancer remains to be surgery. Over the last decades, surgical strategies have evolved remarkably. When neoadjuvant chemoradiotherapy became standard, discussions about the role, type, and timing of surgery began. In this study, we share results we obtained after operating our patients using various surgical techniques. Material and Methods: Reliable data from 51 esophageal cancer patients were evaluated retrospectively. Of the 51 cases, 31 were operable. These operable cases were further classified according to surgical method and neoadjuvant therapy status. Median survival time in months, complications, hospital mortality, length of hospital stay, and pathology results (total lymph nodes harvested and pathologic tumor node metastasis stage [p_TNM]) were documented for the different surgical approaches. Results: Open surgical methods were performed in 21 cases, while in 10 cases the Minimally Invasive Surgery (MIS) method was used. The MIS group received neoadjuvant therapy more frequently than the open surgical methods group (p=0.013). Although more complications were observed in the MIS group, the difference to the open esophagectomy methods group was not significant. Patients in the MIS group also had longer hospital stays, but again the difference was not significant. Although a pathologic complete response was seen in 8 of the 11 (72.7%) patients in our study who received chemoradiotherapy as neoadjuvant treatment, the surgical results of patients who received chemoradiotherapy were worse, although not to a statistically significant extent. Conclusion: Despite changing trends and treatment options in esophageal cancer surgery, we have yet to see the expected improved results.

Introduction: Esophageal cancer is the sixth cause of cancer related deaths worldwide. Esophagectomy is the standard treatment for non-metastatic esophageal cancer, but is associated with high mortality and morbidity rates. We evaluated the mortality and complications following esophagectomy, and factors affecting it (including the surgical approach). Methods: This retrospective study was performed from 2006 to 2012; the data were collected from medical files of esophageal cancer patients who underwent surgical procedures at Iran's cancer institute and analyzed. Results: A total of 254 operated esophageal cancer patients entered this study. Patients included 105 males and 149 females, with a mean age of 65.70. Of all the operated patients, 121 (47.64%) underwent the trans-hiatal and 121 (47.64%) the transthoracic esophagectomy method, also 12 patients were operated by other surgical methods. Post-operative complications occurred in 61 patients (24.02%). Respiratory complications (20.08%)-including Adults Respiratory Distress Syndrome (9.45 %), pneumonia (6.30%) and ventilator dependency (4.33%)-were the most common complications. Other major complications were anastomosis leakage and fistula (6.30 %), atrial fibrillation (6.30 %), chylothorax (3.15%), bleeding requiring reoperation (1.97%) and pulmonary embolism (1.97 %). In-hospital mortality rate was 5.12 %. Pneumonia, ICU admission and intubation time were significantly higher in transthoracic than trans-hiatal method but mortality was not significantly different. ARDS, ventilator dependency and history of cardio-pulmonary disease were prognostic for in-hospital mortality. Conclusion: Although esophagectomy is a complex surgery and associated with multiple complications, in case of proper patient selection and experienced surgeons, both the transthoracic and trans-hiatal esophagectomy methods have appropriate results.

Background: The feasibility and the safety of the thoraco-laparoscopic esophagectomy (TLE) was proved by several prominent academic institutions. This technique is technically challenging and requires advanced laparoscopic and thoracoscopic skills. With experience gained from open esophagectomy as well as laparoscopic surgery, thoraco-laparoscopic esophagectomy was introduced in our hospital in 2016. We report our experience in performing TLE. Materials and Methods: We conducted a prospective, nonrandomized, observational study in Hue central hospital, which is one of the biggest hospitals in Vietnam, from January 2016 to January 2021. This study included the esophageal cancers that were diagnosed by endoscopy and confirmed by pathology. Esophageal cancer with cT1b-3N0M0 using chest CT, ultrasound-endoscopy, abdominal CT was indicated for resection initially, while esophageal cancer with cT4N0M0 or T3N(+)M0 was indicated for resection after neoadjuvant therapy. The patients had the ASA I-III. All the data were analyzed statistically using SPSS software (SPSS, Inc, Chicago, IL). Results: We used the TLE technique to operate for 52 consecutive patients. All patients were in a semi-prone position. The male/female ratio was 47/5. The mean age was 57.3±6.3 years, and the mean BMI was 20.5±3.3 kg/m 2. The preoperative location of the esophageal cancer was the upper one-third in two (3.8%), the middle one-third in 24 (46.1%), and the lower one-third in 26 (50.0%). The majority of our patients had cTNM stage II (30, 57.7%). Only seven patients (13.7%) had cTNM stage I, whereas 15 patients (31.4%) had cTNM stage III. Of the 45 patients (stage II and III) who needed the neoadjuvant therapy, 30 (57.7%) received short-courses, 15 (28.8%) received long-course of chemotherapy. For 24 patients (46.1%), the histopathology was squamous cell carcinoma. The remaining 28 patients (53.8%) had adenocarcinomas. The operative time was 311.2±45.9 minutes. We did not record either conversion or intraoperative events. The mortality and morbidity rates were 1.9% and 23%, respectively. The hospital stay was 15.6±7.2 days. The median follow-up time was 22±1.5 months, and the overall survival rate at one year was 84.7%. Conclusion: Thoraco-laparoscopic esophagectomy for esophageal cancer with the patient in a semi-prone position is safe and effective, including the lower morbidity rate and the shorter operative time while preserving the long-term outcomes.
Background Minimally invasive surgery is becoming widely adopted to decrease surgical morbidity and mortality, however data is still evolving and the optimal approach remains an area of controversy. We compared our unique single-institution experience with transhiatal, transthoracic, and minimally invasive approaches to examine survival and toxicity outcomes among patients treated for esophageal cancer. Methods Consecutive patients undergoing esophagectomy for esophageal or gastroesophageal junction (GEJ) cancer at a single institution between 2008 and 2017 were retrospectively reviewed. The patients were stratified by surgical approach. The Kaplan-Meier method was performed using the log-rank test to calculate two-year overall survival (OS) and two-year progression-free survival (PFS). Results A total of 198 consecutive patients were identified: 118 transhiatal esophagectomy (THE), 34 Ivor Lewis esophagectomy (ILE), and 46 minimally invasive esophagectomy (MIE) with a median follow-up of 30.0 months (range, 0.5-136.9 months). Most tumors were adenocarcinoma (89.9%) located in the distal esophagus and GEJ (94%). Neoadjuvant chemoradiotherapy was received by 75.8% of patients. Length of hospitalization, readmission rate, perioperative adverse events, reoperation rates, tracheoesophageal fistula, anastomotic leak, anastomotic stenosis, and 30-day mortality were comparable. Two-year overall survival rates for MIE, THE, and ILE were 71.7%, 67.8%, and 58.8%, respectively (p=0.003). Progression-free survival at 2 years for MIE, THE, and ILE were 69.6%, 58.5%, and 35.3%, respectively (p=0.002). Conclusion Minimally invasive esophagectomy is an effective approach which results in comparable perioperative complications and long-term survival outcomes to a transhiatal approach. Minimally invasive esophagectomy can safely be performed and should continue to be studied prospectively.
