Esophageal leiomyoma and simultaneous overlying squamous cell carcinoma: a case report and review of the literature

BackgroundSquamous cell carcinoma is the most common epithelial tumor of the esophagus. Upper endoscopy with multiple minimally invasive biopsies should be performed to confirm the diagnosis. Leiomyoma of esophagus is rare, but it’s the most common benign submucosal mesenchymal tumor of the esophagus. The simultaneous occurrence of an overlying epithelial lesion and a mesenchymal lesion is very rare. This study aims to show a case operated due to squamous cell carcinoma of esophagus that was postoperatively diagnosed with coexistent esophageal leiomyoma and give a clear overview of the existing literature on it.Case presentationThe patient was a 41-year-old woman who underwent three field esophagectomy (McKeown). Pathological evaluation was done, and the patient had poorly differentiated squamous cell carcinoma and multiple leiomyomas. A leiomyoma was found with an invading overlying squamous cell carcinoma.ConclusionIt is concluded that esophageal carcinomas may coexist with leiomyomas; preexisting benign tumors may have played an important role in the development of the carcinoma by inducing constant stimulation of the overlying mucosa; endoscopic ultrasonography is recommended to avoid overestimating the extent of tumor invasion and the resultant aggressive radical surgery. As the developing countries had limited equipment, esophageal resection could be the modality of choice in the treatment.

Esophageal Cancer Surgery in Dialyzed Patients: A Single Institution Case Series.

We sought to evaluate the feasibility of esophageal carcinoma (EC) surgery in cases requiring dialysis. Among 250 consecutive patients undergoing surgical resection for EC, three on maintenance dialysis were identified. We retrospectively analyzed their clinical characteristics. The three dialyzed patients were all males, 39-77 years old at EC surgery. The operations were thoracoscopic esophagectomy with nodal clearance (Case 1), cervical esophageal resection without thoracic procedures (Case 2), and thoracoscopic esophagectomy without reconstruction, emergently conducted for tumor bleeding (Case 3). Reoperation had been required for postoperative abdominal hematoma in Case 1. Postoperative tracheostomy had been performed due to severe pneumonia in Case 2. EC surgery for dialyzed patients, despite appearing to be feasible, might be associated with a high risk of life-threatening morbidities. To minimize surgical risk, therapeutic decision-making for such cases should be based on the balance between radicality and safety.

The endoscopic “hide-bound” bowel sign in systemic sclerosis

A 56-year-old woman presented for EGD because of progressive reflux symptoms despite taking high-dose pantoprazole. Her medical history was significant for systemic sclerosis with acro-osteolysis and digital ulcers. Four years earlier, she had undergone distal esophageal resection elsewhere for a refractory stricture. The recent endoscopy indicated Los Angeles grade D reflux esophagitis with an inconspicuous esophagogastric anastomosis and stomach. However, the duodenal lumen appeared grossly dilatated, with peristalsis virtually completely abrogated.

Robotic esophagectomy: results from a tertiary care Italian center.

There is growing evidence supporting the use of minimally invasive resection in esophageal surgery, mainly due to reduced postoperative morbidity and faster recovery after surgery. In recent years, robot-assisted surgery has shown some potential benefits over conventional laparo-thoracoscopic esophagectomy. The purpose of this study is to report our experience with different esophageal resections with a full-robotic approach for malignant disease. All consecutive patients with resectable esophageal malignancy undergoing robotic esophagectomy over a 6-year time frame by a single surgical team were included in this analysis. Perioperative and clinicopathological outcomes were assessed. A total of 76 patients received robotic esophagectomy. Surgeries included 45 Lewis procedures, 25 McKeown procedures, and six transhiatal resections. There were no intraoperative complications and no conversions occurred. The rate of postoperative morbidity was 41%, while the rate of anastomotic leak was 13%. Overall, eight patients required reintervention. All patients received R0 resection, with a median of harvested lymph nodes of 35. 30-day and 90-day mortality was 3.9 and 7.9%, respectively. Our findings support the safety and oncological efficiency of full-robotic esophagectomy. All procedures of esophageal resection were associated with the expected perioperative morbidity while providing excellent pathological outcomes for patients with malignancy.

Robotic video-assisted thoracoscopic surgery using multiport triangular trocar configuration: initial experience at a single center

BackgroundRecent developments in robotic technology have brought significant changes in robotic video-assisted thoracoscopic surgery (r-VATS) worldwide, particularly including the treatment in the thorax for the mediastinal, esophagus, and pulmonary lesions. Currently, there are only a few reports describing the procedural experience and outcomes with r-VATS. The objective of this study is to provide our initial experience using r-VATS at a single center, with specific attention to safety, efficacy, and procedural details.MethodsWe retrospectively reviewed patients who underwent a newly modified r-VATS procedure for various surgical operations at the thoracic department of our hospital, from July 2018 to January 2020. Multiport trocars were placed in the classic triangular arrangement as in conventional VATS (c-VATS) but with modifications based on the type of surgery. The peri- and postoperative outcomes such as duration of surgery, complications, and duration of hospital stay for these patients were reported.ResultsOverall, 142 patients underwent r-VATS for lobectomy (66), wedge resection (15), thymectomy (22), mediastinal tumor resection (30), pneumonectomy (4), transthoracic esophagectomy (1), esophageal tumor resection or esophageal diverticulum repair (2), diaphragm plication (1), and mediastinal tumor resection plus thymectomy (1). For the entire cohort, the median operative time was 110 min, and the median length of hospital stay was 5 days. Conversion to open thoracic surgery was reported only in a total of 3 (2.1%) patients of pneumonectomy (1.4%) and mediastinal tumor resection (0.70%). All our patients were managed successfully with no postoperative complications and mortality.ConclusionOur method of r-VATS was found to be safe and effective and may be applied to different surgical operations. Adequate and proper training of thoracic surgeons is immediately needed for the transition from c-VATS to r-VATS. The utility and advantages of triangular trocar configuration for r-VATS require further refinement and research before it can be routinely adopted in clinical practice.Trial registrationRetrospectively registered.

Safety comparison of minimally invasive abdomen-only esophagectomy versus minimally invasive Ivor Lewis esophagectomy: a retrospective cohort study.

We report mortality and post-operative complications from esophageal resection in the treatment of gastroesophageal adenocarcinoma or stricture, comparing a minimally invasive abdomen-only esophagectomy (MIAE) approach with a minimally invasive Ivor Lewis esophagectomy (MIILE) approach. A single-center retrospective cohort study of patients with esophageal adenocarcinoma or stricture treated by either MIAE or MIILE was conducted. MIAE was offered for strictures less than five centimeters or cancers that were American Joint Committee on Cancer (AJCC) Stage ≤ T2 without lymphadenopathy. Patients treated with these surgical techniques were analyzed to assess pre-operative risk, intra and post-operative variables, adverse events, and overall survival. This study included 17 patients undergoing MIAE and 32 patients treated with MIILE. There were a fewer median number of lymph nodes resected (p < 0.001) and shorter operative duration (p < 0.001) for MIAE compared to MIILE. MIAE patients also had significantly higher Charlson Comorbidity Index scores and ACS National Surgical Quality Improvement Program (NSQIP) surgical risk values than MIILE patients (p < 0.05). There was no difference in median estimated blood loss, length of stay, pulmonary or cardiac complications between groups. There was no significant difference in 90-day survival. A minimally invasive abdomen-only approach in a specific patient population is comparable in safety to a minimally invasive Ivor Lewis approach, with associated shorter median operative duration. MIAE patients had significantly greater pre-operative comorbidities and higher calculated peri-operative risk of complication but demonstrated similar post-operative outcomes. This suggests that MIAE may be a suitable surgical approach for treating gastroesophageal adenocarcinoma or stricture in patients deemed unsuitable for MIILE.

Manual and mechanical cervical esophagogastric anastomosis after esophageal Resection: A comparison

Anastomotic complications after esophagectomy continue to be a burden jeopardizing the quality of life and of swallowing. However, incidence, mortality and morbidity of anastomotic complications have substantially decreased in recent years. It seems that this is not so much related to the use of a particular conduit, approach or route for reconstruction, but rather related to refinement in anastomotic techniques and perhaps even more to progress in modern perioperative management. Knowledge of surgical anatomy and meticulous technique are of paramount importance and obviously related to individual expertise. Aims 1. To compare the rates of anastomotic leaks after cervical esophagogastric anastomosis (CEGA) done by hand-sewn (end-to-side) technique and by linear stapled anastomosis (side-to-side) technique. 2. To compare the rates of postoperative anastomotic stricture after cervical esophagogastric anastomosis (CEGA) done by hand-sewn (end-to-side) technique and by linear stapled anastomosis (side-to-side) technique. Index terms: Cervical Esophagogastric Anastomosis (CEGA), Esophagectomy, Esophageal Resection, Anastomotic leaks, Hand sewn anastomosis, Stapled anastomosis, gastrostomy.

Application of mediastinal drainage tube in intrathoracic esophageal anastomotic leakage for early diagnosis and effective treatment: a retrospective study

BackgroundIntrathoracic esophageal anastomotic leakage (AL) is one of the most fatal complications after esophagectomy. In this study, we placed an additional drainage tube in the esophagus bed and evaluated its effect in early diagnosis and treatment of AL.MethodsFrom January 2010 to August 2020, 312 patients with esophageal or cardia carcinoma underwent esophageal resection with intrathoracic esophagogastric anastomosis. A total of 138 patients with only one pleural drainage tube were divided into the “Control Group” and 174 patients with a pleural drainage tube and an additional mediastinal drainage tube (MDT) were divided into the “Tube Group”. For all patients, the incidence of postoperative AL, the time to diagnosis, time to recovery, and patient outcome were analyzed.ResultsNo significant differences were observed in the AL rate (P = 0.837) and postoperative pain between two groups. However, in the Tube Group, almost all the patients were diagnosed prior to the appearance of hyperpyrexia, which was considered as the earliest and most common symptom after AL. In the Tube Group, a significant decrease was observed in the incidence of incurable fistula, which required re-operation or variable treatments under gastroscopy when compared to the Control Group (P = 0.032). Finally, patients in the Tube Group showed reduced post AL hospital day (P = 0.015) and a lower mortality, however, when compared to the Control Group, no significant differences were observed (P = 0.188).ConclusionsPlacement of an MDT does not prevent AL, but it is an effective approach for earlier diagnosis of AL and facilitates fistula healing and patient recovery.

Outcomes of Esophageal Stent Therapy for the Management of Anastomotic Leaks.

The purpose of this study was to present the optimal patient selection for esophageal stenting after esophageal resection to investigate possible factors leading to treatment success or treatment failure in these patients. This was a prospective, observational study of patients from January 2005 to May 2019 with an esophageal anastomotic leak that were treated with a self-expandable stent (SES). A total of 34 patients were treated. All achieved technical success (100%); 33 (97%) achieved clinical success. No patient had to have reoperative surgery based on their leak management. The stenting in-hospital mortality was 0% with 1 patient (2%) with a 90-day mortality from possible leak-related death. Patients had their stents removed with a median of 106 days. Stenting for an anastomotic leak after resection offers a safe and effective method of treatment and is successful in the majority of cases. Critical to success is optimal patient selection, adequate leak drainage, and optimal stent selection and placement.

Management of chyle leaks following esophageal resection: a systematic review.

SummaryBackgroundChyle leakage is an uncommon but potentially life-threatening complication following esophageal resections. The optimal management strategy is not clear, with a limited evidence base.MethodsSearches were conducted up to 31 December 2020 on MEDLINE, Embase, and Web of Science for randomized trials or retrospective studies that evaluated the management of chyle leakage following esophageal resection. Two authors independently screened studies, extracted data, and assessed for bias. The protocol was prospectively registered on PROSPERO (CRD: 42021224895) and reported in accordance with preferred reporting items for systematic reviews and meta-analyses guidelines.ResultsA total of 530 citations were reviewed. Twenty-five studies, totaling 1016 patients met the inclusion criteria, including two low-quality clinical trials and 23 retrospective case series. Heterogeneity of study design and outcomes prevented meta-analysis. The overall incidence of chyle leak/fistula was 3.2%. Eighteen studies describe management of chyle leaks conservatively, 17 by surgical ligation of the thoracic duct, 5 by pleurodesis, and 6 described percutaneous lymphangiography with thoracic duct embolization or disruption.ConclusionsThe evidence base for optimal management of chyle leakage postesophagectomy is lacking, which may be related to its low incidence. There is a paucity of high-quality prospective studies directly comparing treatment modalities, but there is some low-certainty evidence that percutaneous approaches have reduced morbidity but lower efficacy compared with surgery. Further high-quality, prospective studies that compare interventions at different levels of severity are needed to determine the optimal approach to treatment.

Precut esophageal endoscopic mucosal resection for cervical esophageal cancer to minimize mucosal defect.

A 72-year-old man underwent esophagogastroduodenoscopy (EGD) for heartburn. Two adjacent, iodine-unstained, shallow depressed lesions, 25 mm and 8 mm in size, were found in the cervical esophagus ([Fig. 1]). Biopsies revealed squamous cell carcinoma (SCC). The patient opted for endoscopic resection.

Minimally Invasive Esophagectomy the Standard of Care: Experience from a Tertiary Care Cancer Center from India.

For localized esophageal cancer, esophageal resection remains the prime form of treatment but is a highly invasive procedure associated with prohibitive morbidity. Minimally invasive esophagectomy (MIE) by laparoscopic or thoracoscopic approach was therefore introduced to reduce surgical trauma and its associated morbidity. We thereby review our minimally invasive esophagectomy results with short- and long-term outcomes. From January 2010 through December 2016, 459 patients with carcinoma esophagus and gastro-esophageal junction undergoing minimally invasive esophagectomy were retrospectively reviewed. The morbidity, mortality data with short- and long-term results of the procedure were studied. Patients were stratified into two arms based on the approach into minimally invasive transhiatal esophagectomy (MI-THE) and minimal invasive transthoracic esophagectomy TTE (MI-THE). Thirty days mortality in the whole cohort was 3.5% (2.5% in MI-THE vs. 5% in MI-TTE arm). Anastomotic leak rates (5 vs. 4.9%), median intensive care unit (ICU) stay (4days), hospital stay (9days), were similar between both the approaches. Major pulmonary complications were significantly higher in MI-TTE arm (18.9% vs 12.5%) (p 0.047). Cardiac, renal, conduit-related complication rates, vocal cord palsy, chyle leak, re-exploration, and late stricture rates were similar between the groups. The median number of nodes resected was higher in the MI-TTE arm (14 vs. 12) (p 0.002). R0 resection rate in the entire cohort was 89% (87.4% in MI-THE, 92% in MI-TTE arm p 0.12). The median overall survival and disease-free survival were also not different between MI-THE and MI-TTE arms (34 vs. 38months, p 0.64) (24 vs. 36months, p 0.67). Minimally invasive esophagectomy either by transhiatal or transthoracic approach is feasible and can be safely accomplished with a low morbidity and mortality and with satisfactory R0 resection rates, good nodal harvest, and acceptable long-term oncological outcomes.

Minimally invasive transhiatal esophagectomy

: While traditionally performed through an open approach, the role of minimally invasive technologies has evolved in its application to esophageal resection. Esophagectomy is associated with significant morbidity, which has led to interest in developing minimally invasive esophagectomy (e.g. , laparoscopic/thoracoscopic approaches) to address this issue. As a result, the role of minimally invasive approaches for esophageal resection has evolved, with a growing body of literature describing these techniques. Minimally invasive approaches have been applied to transhiatal esophagectomy, with application of both laparoscopic and robotic-assisted techniques. Although minimally invasive esophagectomy approaches are well-described in the literature for esophageal malignancies, the efficacy of robotic-assisted esophagectomy is not as well established. Since the initial reports of this application, the adoption of this technology for esophagectomy has continued to expand. As the role for robotic techniques has expanded across esophageal resection approaches, a more defined application to minimally invasive transhiatal esophagectomy (MI-THE) has developed. Our group has sought to adapt laparoscopic and robotic techniques to the transhiatal approach for both malignant and end-stage benign esophageal disease. With growing MI-THE experience, operative technique has been further refined. This report describes the operative technique and best practices for robotic-assisted transhiatal esophagectomy with cervical esophagogastric anastomosis, including preoperative preparation, operative technique, postoperative care, and perioperative outcomes.

The ratio of gastric tube length to thorax length: a vital factor affecting leak after esophageal cervical anastomosis.

BackgroundEsophagogastric anastomotic leak (AL) is a severe complication following esophageal resection. This study aims to explore preliminarily whether the ratio of the gastric conduit length to the thorax length can be regarded as a potential prognostic variable for AL, and if so, a cut-off value can be found to divide the patients into distinct risk groups.MethodsWe retrospectively reviewed the clinical data of 273 patients who underwent esophagectomy. The gastric conduit length, the thorax length, and other covariates were collected. Logistic regression was first conducted to probe the rationality of the ratio as a risk indicator of AL. Then the dichotomizing analysis was applied to find the optimal cut-off value.ResultsThe incidence of AL was 12.5% (34/273). The coefficient of the ratio in the logistic regression equation was –7.901 with P<0.001, which indicated that the larger the ratio, the smaller the risk of AL. Further smoothed scatter plots revealed that a potential step function of the ratio of AL incidence exists, of which the steep part ranges from 1.74 to 1.90. Results of the accurate cut-off value search through a minimum P value approach give the optimal dichotomization point of 1.79.ConclusionsThe ratio of the gastric conduit length to the thorax length can reflect the tension in the anastomosis. The research proposes that surgeons can control the length of the gastric conduit during reconstruction to reduce the tension in the anastomosis and thus lead to a decrease in the incidence of AL.

Feasibility, effectiveness, and safety of endoscopic vacuum therapy for intrathoracic anastomotic leakage following transthoracic esophageal resection

BackgroundAnastomotic leakage (AL) in the upper gastrointestinal (GI) tract is associated with high morbidity and mortality rates. Especially intrathoracic anastomotic leakage leads to life-threatening complications. Endoscopic vacuum therapy (EVT) for anastomotic leakage after transthoracic esophageal resection represents a novel concept. However, sound clinical data are still scarce. This retrospective, single-center study aimed to evaluate the feasibility, effectiveness, and safety of EVT for intrathoracic anastomotic leakage following abdomino-thoracic esophageal resection.MethodsFrom March 2014 to September 2019 259 consecutive patients underwent elective transthoracic esophageal resection. 72 patients (27.8%) suffered from AL. The overall collective in-hospital mortality rate was 3.9% (n = 10). Data from those who underwent treatment with EVT were included.ResultsFifty-five patients were treated with EVT. Successful closure was achieved in 89.1% (n = 49) by EVT only. The EVT-associated complication rate was 5.4% (n = 3): bleeding occurred in one patient, while minor sedation-related complications were observed in two patients. The median number of EVT procedures per patient was 3. The procedures were performed at intervals of 3–5 days, with a 14-day median duration of therapy. The mortality rate of patients with AL was 7.2% (n = 4). Despite successfully terminated EVT, three patients died because of multiple organ failure, acute respiratory distress syndrome, and urosepsis (5.4%). One patient (1.8%) died during EVT due to cardiac arrest.ConclusionsEVT is a safe and effective approach for intrathoracic anastomotic leakages following abdomino-thoracic esophageal resections. It offers a high leakage-closure rate and the potential to lower leakage-related mortalities.Trial registration: This trial was registered and approved by the Institutional Ethics Committee of the University of Heidelberg on 16.04.2014 (Registration Number: S-635/2013).

Mentoring in Pediatric Thoracoscopy: From Theory to Practice.

Introduction: Thoracoscopy represents the most challenging area of pediatric minimally invasive surgery due to its technical difficulty. A standardized training program would be advisable. The aim of this study is to evaluate the results of our surgical training.Materials and Methods: A retrospective, single-center, cohort study was performed. The following four-step program was tested: (1) theoretical part; (2) experimental training; (3) training in centers of reference; (4) personal operative experience. Particular attention was focused on the choice of mentor. Times and modality of adherence to the program were evaluated. The effectiveness and safety of the training were evaluated according to the surgical results of esophageal atresia (EA/TEF) repair and resection of congenital lung malformations (CLM). The study was conducted from January 2014 to May 2020. Attending surgeons with previous experience in neonatal and pediatric laparoscopy were selected for the training program after being evaluated by the head of Department.Results: The training program was fully completed in 2 years. Twenty-four lobectomies, 9 sequestrectomies, 2 bronchogenic cyst resections and 20 EA/TEF repair were performed. Thoracoscopy was always feasible and effective, with no conversion. The operative times progressively decreased. Only three minor complications were recorded, all treated conservatively.Conclusions: A standardized training program is highly desirable to learn how to safely perform advanced pediatric thoracoscopy. The 4-steps design seems a valid educational option. The choice of the mentor is crucial. An experience-based profile for pediatric surgeons who may teach thoracoscopy is advisable.

Effect of Posterior Tracheopexy on Risk of Recurrence in Children after Recurrent Tracheo-Esophageal Fistula Repair

A recurrent tracheo-esophageal fistula can complicate esophageal atresia and tracheo-esophageal fistula (TEF) repair in children. Therapeutic approaches and the rate of recurrence vary widely. Most reports are limited by small cohorts and short-term follow-up, and rates of re-recurrence are substantial, making it difficult to select the treatment of choice. We aimed to review our experience with the treatment of recurrent TEF using posterior tracheopexy, focusing on operative risks and long-term outcomes. We conducted a retrospective review of patients with esophageal atresia TEF with recurrent TEF treated at 2 institutions from 2011 to 2020. We approach recurrent TEFs surgically. Once the TEF is divided and repaired, the membranous trachea is sutured to the anterior longitudinal ligament of the spine (posterior tracheopexy) and the esophagus is rotated into the right chest (rotational esophagoplasty), separating the suture lines widely. To detect re-recurrence, patients undergo endoscopic surveillance during follow-up. Sixty-two patients with a recurrent TEF were surgically treated (posterior tracheopexy/rotational esophagoplasty) at a median age of 14 months. All had significant respiratory symptoms. On referral, 24 had earlier failed endoscopic and/or surgical attempts at repair. Twenty-nine required a concomitant esophageal anastomotic stricturoplasty or stricture resection. Postoperative morbidity included 3 esophageal leaks, and 1 transient vocal cord dysfunction. We have identified no recurrences, with a median follow-up of 2.5 years, and all symptoms have resolved. The surgical treatment of recurrent TEFs that incorporates a posterior tracheopexy and rotational esophagoplasty is highly effective for preventing re-recurrence with low perioperative morbidity.

Generation of a surgical field at the mid-lower mediastinum for thoracoscopic esophagectomy in the left lateral decubitus position: Case series

IntroductionThe generation of a good surgical field at the mid-lower mediastinum during thoracoscopic esophagectomy in the left lateral decubitus position is often complicated. Here, we developed a simple and useful technique for surgical field generation. MethodsAmong 225 patients who underwent esophageal resection from April 2015 to December 2019, 154 underwent thoracoscopic esophagectomy using our following-described method.The patients are placed in the left lateral decubitus position similarly to open thoracotomy, and a 12-mm port is inserted at the midaxillary line in the third, fifth, and seventh intercostal spaces and anterior to the inferior angle of the scapula in the ninth (scope port). A 5-mm port is inserted at the inferior angle of the scapular line in the sixth and eighth. The mid-lower mediastinal procedure is performed first, with the operator and camera holder positioned at the ventral side and the assistant at the dorsal side of the patient. A camera displays the surgical field on the monitor as in the prone position. Thoraco-cotton with a stainless-steel shaft is inserted through the third port to compress the upper and lower lobes of right lung and simultaneously make counter traction to the ventral side of the esophagus. ResultWe hardly encounter any difficulty with surgical field generation in the middle-lower mediastinum without one patient having abnormal divergence of right superior lobar branch, or any patients with intraoperative complications. ConclusionOur newly described method is very simple and easily adapted for thoracoscopic esophagectomy in the left decubitus position.

Enteral immunonutrition versus enteral nutrition for patients undergoing esophagectomy: a randomized controlled trial.

In recent years, immunonutrition has been introduced and proposed to have a positive modulatory effect on inflammatory and immune responses and gut function for surgical patients, especially for patients undergoing gastrointestinal cancer resection. We conducted this parallel-group, randomized and double-blind clinical controlled trial to investigate the efficacy of perioperative enteral immunonutrition (EIN) on clinical and immunological outcomes of patients undergoing esophageal resection. A randomized, parallel-group, double-blind, clinical trial was conducted between December 1, 2017 and March 1, 2018. This study enrolled 120 patients with esophageal cancer. And 112 patients were divided into two groups randomly: EIN group and enteral nutrition (EN) group. The EIN contained extra immunonutritional substrates, including a consistent combination of arginine, RNA and the omega-3 fatty acids compared with EN. Immune indicators were measured at preoperative day 7, postoperative day (POD) 1, 3, 7 and post-discharge day (PDD) 30. There were 56 participants randomized to each group. Finally, 53 patients in EIN and 50 patients in EN were analyzed. Immune indicator was the primary outcome in this study. EIN yielded a significantly lower rate of CD8/CD3 (%) at POD 3 compared with EN group (P=0.005). The rate of CD4/CD8 (%) in EIN group was higher than that in EN group at POD3 (P=0.004). The serum levels of IgM at POD 3 and 7 were significantly higher in EN group compared with EIN group (P=0.025 and P=0.009, respectively). The rate of NK (%) and the serum level of IgA were significantly higher in EIN group compared with EN group at PDD 30 (P=0.022 and P=0.041, respectively). No significant differences were found in 2-year progressionfree survival and overall survival. Immunonutrition is a safe and feasible nutritional treatment, which has a positive modulatory impact on immune responses after esophagectomy. Although no significant difference was found in clinical and survival outcomes between EIN and EN groups, immunonutrition could still have a positive effect on immunological function of patients undergoing esophagectomy.
