ABSTRACT
Objective: To investigate the outcome of patients with esophagogastric junction cancer undergoing thoracoscopic laparoscopy-assisted Ivor-Lewis resection. Methods: Eighty-four patients who were diagnosed with esophagogastric junction cancer and underwent Ivor-Lewis resection assisted by thoracoscopic laparoscopy at the National Cancer Center from October 2019 to April 2022 were collected. The neoadjuvant treatment mode, surgical safety and clinicopathological characteristics were analyzed. Results: Siewert type Ⅱ (92.8%) and adenocarcinoma (95.2%) were predominant in the cases. A total of 2 774 lymph nodes were dissected in 84 patients. The average number was 33 per case, and the median was 31. Lymph node metastasis was found in 45 patients, and the lymph node metastasis rate was 53.6% (45/84). The total number of lymph node metastasis was 294, and the degree of lymph node metastasis was 10.6%(294/2 774). Among them, abdominal lymph nodes (100%, 45/45) were more likely to metastasize than thoracic lymph nodes (13.3%, 6/45). Sixty-eight patients received neoadjuvant therapy before surgery, and nine patients achieved pathological complete remission (pCR) (13.2%, 9/68). Eighty-three patients had negative surgical margins and underwent R0 resection (98.8%, 83/84). One patient, the intraoperative frozen pathology suggested resection margin was negative, while vascular tumor thrombus was seen on the postoperative pathological margin, R1 resection was performed (1.2%, 1/84). The average operation time of the 84 patients was 234.5 (199.3, 275.0) minutes, and the intraoperative blood loss was 90 (80, 100) ml. One case of intraoperative blood transfusion, one case of postoperative transfer to ICU ward, two cases of postoperative anastomotic leakage, one case of pleural effusion requiring catheter drainage, one case of small intestinal hernia with 12mm poke hole, no postoperative intestinal obstruction, chyle leakage and other complications were observed. The number of deaths within 30 days after surgery was 0. Number of lymph nodes dissection, operation duration, and intraoperative blood loss were not related to whether neoadjuvant therapy was performed (P>0.05). Preoperative neoadjuvant chemotherapy combined with radiotherapy or immunotherapy was not related to whether postoperative pathology achieved pCR (P>0.05). Conclusion: Laparoscopic-assisted Ivor-Lewis surgery for esophagogastric junction cancer has a low incidence of intraoperative and postoperative complications, high safety, wide range of lymph node dissection, and sufficient margin length, which is worthy of clinical promotion.

Objective To explore the expression of heat shock protein (HSP) 105b in advanced adenocarcinoma of esophagogastric junction (AEG) patients and its relation with clinicopathological characteristics and effect of hyperthermic intraperitoneal chemotherapy (HIPEC). Methods We randomly divided 166 cases of advanced AEG who underwent open radical gastrectomy and lymphadenectomy D2 compartment into treatment group (prophylactic HIPEC of paclitaxel after operation) and control group (conventional treatment). Immunohistochemistry was used to detect HSP105b expression in postoperative tumor tissues, and to analyze its relation with clinicopathological characteristics and effect of HIPEC. Results The expression of HSP105b was only associated with tumor vein infiltration (t=4.002, P=0.045). The 3-year disease-free survival rate of the patients with high HSP105b expression was significantly lower than those with low HSP105b expression (56.5% vs. 64.8%, χ2=35.508, P < 0.001), and the disease-free survival rate of the patients with high HSP105b expression in treatment group was significantly lower than that with low HSP105b expression (60.7% vs. 71.5%, χ2=77.459, P < 0.001). Conclusion HSP105b can be used as a prognostic factor and its expression can predict the efficacy of HIPEC in the patients with advanced AEG.
ABSTRACT
As early as in the 1960s, China has begun to conduct exploratory clinical researches on gastric cancer. In the past 10 years, the research projects have increased significantly. Among them, the minimally invasive surgery represented by laparoscopy (CLASS Trial), the hot spot of the esophagogastric junction cancer (5010 Trial), the perioperative adjuvant treatment of advanced gastric cancer (CGOG1001 and RESOLVE Trials), the conversion treatment of late gastric cancer (DRAGON Trial) and high quality clinical research such as real-world research based on large database have made great progress. But there are still many deficiencies, such as few multi-center prospective research, limited research return, and the quality and innovation of scientific research data need to be further improved. However, it should also be noted that the clinical researches of gastric cancer in China have greater advantages and development space. The characteristics of large population base, rich cases and large proportion of advanced gastric cancer are conducive to real-world research. In the future, we should follow the international frontier and combine with national conditions to deepen clinical research, so that more "Chinese elements" can be introduced into the international guidelines for gastric cancer, and promote the overall level of diagnosis and treatment of gastric cancer in China.
ABSTRACT
Objective To investigate the pattern of lymph node metastasis and analyze prognostic factors of Siewert type Ⅱ adenocarcinoma of esophagogastric junction (AEG).Methods The retrospective case-control study was conducted.The clinicopathological data of 368 patients with Siewert type Ⅱ AEG who were admitted to Tianjin Medical University Cancer Institute and Hospital from June 2010 and November 2015 were collected.There were 323 males and 45 females,aged from 35 to 80 years,with an average age of 64 years.Of 368 patients,209 underwent left transthoracic surgery,1 12 underwent thoracoabdominal surgery,and 47 underwent Ivor-Lewis surgery.Observation indicators:(1) total lymph node metastasis and metastasis of various lymph node stations;(2) follow-up and survival;(3) prognostic factors analysis;(4) influencing factors affecting thoracic lymph node metastasis.Follow-up using outpatient examination and telephone interview was performed to detect survival of patients up to November 2018.Measurement data with skewed distribution were represented as M (range).Count data were represented as absolute number or percentage.The survival time and rate were calculated using the Kaplan-Meier method.The univariate and multivariate analyses were done by the COX proportional hazard model.Results (1) Total lymph node metastasis and metastasis of various lymph node stations:the total lymph node metastasis rate was 66.58％ (245/368) in 368 patients.The metastasis rates of abdominal lymph nodes,thoracic lymph nodes,lower mediastinal lymph nodes,and upper mediastinal lymph nodes were 65.49％ (241/368),12.77％ (47/368),12.23％ (45/368),and 1.09％ (4/368),respectively.The order of metastasis rate of various lymph node stations from high to low was 51.99％(170/237) of No.7 left gastric artery,34.23％(89/260) of No.1 right paracardial region,33.88％ (83/245) of No.2 left paracardial region,28.91％ (85/294) of No.3 lesser curvature,27.10％(29/107) of No.1 1 splenic artery,19.75％(16/81) of No.9 celiac trunk,15.25％(36/236) of No.E8Lo lower paraesophageal region,11.94％ (16/134) of No.4 greater curvature,11.76％ (6/51) of No.E8M middle paraesophageal region,11.1 1％(10/90) of No.8 common hepatic artery,4.65％(4/86) of No.E9L left inferior pulmonary ligament and 3.39％ (2/59) of No.E7 subcarinal region.(2) Follow-up and survival:of the 368 patients,309 were followed up for 1-103 months,with a median follow-up time of 38 months.The survival time of 309 patients was 0.7-101.9 months,and the median survival time was 35.9 months.During the followup,the postoperative l-,2-,3-year overall survival rates were 85.9％,68.6％,and 58.7％,respectively.(3) Prognostic factors analysis.Results of univariate analysis showed that tumor differentiation degree,presence of thoracic lymph node metastasis,number of metastatic lymph nodes,T staging,tumor diameter,and length of esophageal invasion were associated factors affecting prognosis of patients (x2 =8.776,26.582,46.057,18.679,22.460,9.158,P＜0.05).Results of multivariate analysis showed that presence of thoracic lymph node metastasis,number of metastatic lymph nodes,T staging,and tumor diameter were independent influencing factors for prognosis of patients [odds ratio (OR) =1.699,1.271,1.422,1.238,95％ confidence interval:1.102-2.621,1.019-1.481,1.090-1.856,0.971-1.481,P＜0.05].(4) Influencing factors affecting thoracic lymph node metastasis:results of univariate analysis showed that tumor diameter,length of esophageal invasion,number of lymph lodes harvested in thorax were related factors for thoracic lymph node metastasis (x2 =5.129,43.140,10.605,P＜0.05).Results of multivariate analysis showed that length of esophageal invasion ≥2 cm,number of lymph lodes harvested in thorax ≥ 4 were independent risk factors for thoracic lymph node metastasis (OR =6.321,1.097,95％ confidence interval:2.982-13.398,1.026-1.173,P＜0.05).Conclusion Lymph node metastasis of Siewert type Ⅱ AEG spreads two regions,mainly at abdominal lymph nodes,followed by the thoracic lymph nodes.Presence of thoracic lymph node metastasis,number of metastatic lymph nodes,T staging,and tumor diameter are independent influencing factors for prognosis of patients.Presence of thoracic lymph node metastasis indicates poor prognosis of patients.Length of esophageal invasion ≥ 2 cm and number of lymph lodes harvested in thorax ≥4 are independent risk factors for thoracic lymph node metastasis.
ABSTRACT
Surgical approaches for adenocarcinoma of esophagogastric junction have become controversial issues in recent years,including complete resection of tumors,negative proximal margin,complete lymph node dissection,safety of digestive tract reconstruction and reduction of perioperative complications.JCOG9502 trial in Japan is a well-known clinical trial on the surgical approach for adenocarcinoma of esophagogastric junction,which provides evidence-based medicine results for the transabdominal or transthoracic approach.However,due to the differences between the left and right thoracic approaches,the choice of a reasonable surgical approach has also become the focus of discussion between eastern and western scholars.With the development of minimally invasive surgery,it is possible to perform the operations combining laparoscopy and thoracoscopy in the future.
ABSTRACT
Objective To investigate clinical effects and prognostic factors of transabdominal laparoscopic-assisted and open radical resection for Siewert type Ⅱ and Ⅲ adenocarcinoma of the esophagogastric junction (AEG).Methods The retrospective cohort and case-control studies were conducted.The clinicopathologieal data of 84 patients with Siewert type Ⅱ and Ⅲ AEG who were admitted to the First Affiliated Hospital of Xiamen University from January 2014 to January 2017 were collected.Among 84 patients,42 undergoing transabdominal laparoscopic-assisted radical gastectomy (LARG) were allocated into LARG group and 42 undergoing transabdominal open radical gastectomy (ORG) were allocated into ORG group.Observation indicators:(1) comparison of intraoperative and postoperative recovery situations between groups;(2)comparison of follow-up and survival situations between groups;(3) prognostic analysis of patients with Siewert type Ⅱ and Ⅲ AEG undergoing transabdominal radical resection.Follow-up using outpatient examination and telephone interview was performed to detect postoperative survival situations,tumor recurrence and metastasis of patients up to January 2018.Measurement data with normal distribution were representde as-x±s,and comparison between groups was analyzed using the t test.Measurement data with skewed distribution were described as M (range).Comparison of count data were analyzed using the ehi-square test or Fisher exact probability.Ordinal data were compared between groups using the Mann-Whitney U nonparametric test.The survival rate and curve were respectively calculated and drawn by the Kaplan-Meier method,and Log-rank test was used for survival and univariate analyses.Multivariate analysis was done by COX proportional hazard model.Results (1) Comparison of intraoperative and postoperative recovery situations between groups:patients with Siewert type Ⅱ and Ⅲ AEG in the LARG and ORG group underwent successful transabdominal radical resection,without conversion to thoracotomy.All patients in the LARG group underwent esophagojejunostomy with circular stapler device,38 and 4 patients in the ORG group underwent esophagojejunostomy with circular stapler and linear cut stapler respectively.Operation time,volume of intraoperative blood loss,length of incision,time of postoperative analgesia,cases with anastomotic bleeding,anastomotic leakage,abdominal bleeding,incisional infection,pulmonary infection,abdominal infection and reflux esophagitis of grade Ⅰ ～ Ⅱ postoperative complications and duration of postoperative stay were respectively (261±50)minutes,(119±111)mL,(7.8±1.6)cm,(2.1±1.3)days,1,1,0,0,1,0,0,(12.8 ± 1.9) days in LARG group and (216 ± 52) minutes,(230± 178) mL,(17.3± 1.8) cm,(3.4±1.2)days,2,0,2,2,2,1,2,(18.4±15.3)days in ORG group,with statistically significances between groups (t =2.357,2.960,2.195,2.013,x2 =5.486,t =2.125,P＜0.05).All patients with complications were improved by symptomatic treatment.(2) Comparison of follow-up and survival situations between groups:81 of 84patients including 41 in LARG group and 40 in ORG group were followed up for 6-48 months,with a median time of 29 months.The postoperative 2-year overall and tumor-free survival rates were respectively 85.1％ and 82.1％ of 41 patients in LARG group and 83.1％ and 79.3％ of 40 patients in ORG group,with no statistically significance between groups (x2 =0.013,0.049,P＞0.05).(3) Prognostic analysis of patients with Siewert type Ⅱ and Ⅲ AEG undergoing transabdominal radical resection:results of univariate analysis showed that tumor diameter,tumor TNM staging,tumor T staging,tumor N staging and postoperative adjuvant chemotherapy were related factors affecting prognosis of patients with Siewert type Ⅱ and Ⅲ AEG undergoing transabdominal radical resection (x2 =8.349,14.376,9.732,17.250,8.012,P＜0.05).Results of multivariate analysis showed that tumor TNM staging and postoperative adjuvant chemotherapy were independent factors affecting prognosis of patients with Siewert type Ⅱ and Ⅲ AEG undergoing transabdominal radical resection (risk ratio =4.305,0.031,95％ confidence interval:1.858-9.977,0.004-0.246,P＜0.05).Conclusions Transabdominal laparoscopicassisted radical resection for AEG is safe and feasible,with advantage of minimally invasiveness,having equivalent long-term effects compared to open surgery.Tumor TNM staging and postoperative chemotherapy are independent factors affecting prognosis of patients with Siewert type Ⅱ and Ⅲ AEG undergoing transabdominal radical resection.
ABSTRACT
Objective To investigate the clinical efficacy of jejunal interposed single-tract and doubletract reconstruction after proximal gastrectomy for Siewert type Ⅱ and Ⅲ adenocarcinoma of the esophagogastric junction (AEG).Methods The prospective study was conducted.The clinicopathological data of 108 patients with Siewert type Ⅱ and Ⅲ AEG who were admitted to the Affiliated Tumor Hospital of Shanxi Medical University between August 2013 and November 2016 were collected.All the patients underwent proximal gastrectomy and were allocated into the 2 groups by random number table,including patients using single-tract jejunal interposition reconstruction in the single-tract group and patients using double-tract jejunal interposition reconstruction in the double-tract group.Digestive tract reconstruction:after end-to-side anastomosis between distal jejunum and esophagus and side-to-side anastomosis between posterior wall of the gastric remnant and jejunum,single-tract jejunal reconstruction was done through ligating jejunum at 3 cm below the anastomotic stoma,and then side-to-side anastomosis between proximal jejunum and jejunum was performed in the single-tract group.Patients in the double-tract group used the same digestive tract reconstruction,but jejunum was not ligated.The postoperative pathological examinations showed that patients with positive lymph nodes or tumor invading all layers of gastric wall underwent chemotherapy.Observation indicators:(1) intra-and post-operative situations;(2) follow-up situations.Follow-up using telephone interview was performed to detect postoperative complication,gastrointestinal function and body mass index (BMI) up to November 2017.Measurement data with normal distribution were represented as-x± s and comparison between groups was analyzed using t test.Measurement data with skewed distribution were described as M (range),and comparison between groups was analyzed using the nonparametric test.Repeated measurement data were analyzed by the repeated measures ANOVA.Comparisons of count data were done using chi-square test.Ordinal data were analyzed by the Kruskal Wallis H test.Results One hundred and eight patients were screened for eligibility,including 55 in the single-tract group and 53 in the double-tract group.(1) Intra-and post-operative situations:total operation time,digestive tract reconstruction time,volume of intraoperative blood loss,time to initial anal exsufflation,postoperative complications,cases with gastroesophageal reflux,intestinal obstruction and Visick grading ＞ Ⅱ and duration of postoperative hospital stay were respectively (145±26) minutes,(30±6) minutes,(181±37) mL,(53± 16) hours,1,1,1,(10.0±2.4) days in the singletract group and (139±29)minutes,(26±3)minutes,(176±31)mL,(50±17) hours,3,0,3,(9.4±l.4)days in the double-tract group,with no statistically significant difference between groups (t =0.725,0.219,0.162,-0.576,x2 =2.960,5.830,t =-0.993,P＞0.05).Four patients with gastroesophageal reflux received motilium and omeprazole therapy for 2 weeks,and were improved by symptomatic treatment such as increasing the solid food intake.One patient in the single-tract group had internal hernia-induced intestinal obstruction and was cured by reoperation.There was no anastomotic leakage,bleeding,infection,dumping syndrome and gallstone between groups.Of 108 patients,71 underwent 6-cycle SOX chemotherapy,including 67 with perigastric lymph node metastasis and 4 with tumor invading all layers of gastric wall.(2) Follow-up situations:108 patients were followed up for 12.0-48.0 months,with a median time of 28.6 months.During the follow-up,bowel sound in the double-tract group and single-tract group was 8 times / minute (range,5-12 times / minute) and 3 times /minute (range,2-5 times/ minute),with a statistically significant difference between groups (Z=-0.692,P＜0.05).The single food intake,serum gastrin level,ratio of serum pepsinogen Ⅰ and Ⅱ levels and BMI from preoperation to postoperative 12 months were from (1 117± 129)mL to (817± 127)mL,from (12±5)pmol/L to (41±13) pmol/L,from 11.3±2.8 to 5.1±2.2,(65±7)kg to (63±5) kg in the single-tract group and from (1 095±118)mL to (783±80)mL,from (10±4)pmol/L to (40±10)pmol/L,from 12.4±2.9 to 4.2±1.3,from (63±6) kg to (58±6)kg in the double-tract group,respectively,with no statistically significant difference in single food intake,serum gastrin level and ratio of serum pepsinogen Ⅰ and Ⅱ levels between groups (F =0.468,0.108,0.161,P＞0.05).There was a statistically significant difference in changing trend of BMI between groups (F=24.930,P＜0.05).Conclusion Jejunal interposed single-tract and double-tract reconstruction after proximal gastrectomy for Siewert type Ⅱ and Ⅲ AEG have the same surgical safety and don't affect secretion function of gastric remnant,but there are frequent bowel sounds and obvious weight loss.
ABSTRACT
The incidence of adenocarcinoma of the esophagogastric junction (AEG) has been raised in recently years.Comprehensive treatment based on surgical treatment is currently a general strategy for the treatment of AEG.As a minimally invasive treatment,laparoscopic surgery has been gradually applied to the treatment of AEG.Because of the particularity of the anatomy and pathology of AEG,laparoscopic radical resection still has many difficulties and controversies.Up to now,there are a few high-level evidences for the range of lymph node dissection and gastrectomy and the selection of digestive tract reconstruction,and the treatment strategy of total laparoscopic surgery for AEG has not reached a consensus.Therefore,laparoscopic surgery for AEG has gradually become a hot topic in clinical research.Here,combined with the experience of laparoscopic surgery for AEG and the latest guidelines and literatures,authors presented the general strategies for the laparoscopic treatment of AEG in our center.
ABSTRACT
The world-wide incidence of adenocarcinoma of the esophagogastric junction has been on a rise in recent years.Surgical resection plays the most important role in the multimodal management for adenocarcinoma of esophagogastric junction.However,due to distinct anatomical position,biological features,epidemiology and surgical teams,many controversies and different cognitions exist among surgeons from the East and the West,including tumor staging and classification,regional lymphadenectomy,surgical approaches and extents of esophageal and gastric resection.A new TNM classification has renewed the staging system,while traditional Siewert classification still decides clinical surgical strategies.With the development of minimally invasive surgery and early detection for the lesion,it is possible to perform the operations combining laparoscopy and thoracoscopy in the future.A multidisciplinary team from digestive surgery,oncology,radiology and anesthesiology will be essential for optimal diagnosis and management.
ABSTRACT
Esophagogastric junction (EGJ) tumor involves thoracic and celiac cavities due to special lesion location,and its epidemiology and clinical characteristics are different from that of esophageal cancer and gastric cancer.There are many controversies on the etiology,location,staging and surgical treatment of EGJ tumor in the digestive surgery field.Surgical resection is a core method for EGJ tumor,but different surgical procedures are much controverted between thoracic surgery and abdominal surgery.Authors updated the cognition of EGJ tumor and summarized the research progress of surgical treatment through reviewing the recent literatures.
ABSTRACT
Objective To investigate the application value of the curved cutter stapler device combined with trans-orally inserted anvil (OrVil) in the radical resection of Siewert type Ⅱ adenocarcinoma of the esophagogastric junction (AEG).Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 206 patients with Siewert type Ⅱ AEG who were admitted to the Henan Tumor Hospital between March 2011 and March 2016 were collected.All the 206 patients underwent radical resection and 3-step clock wise total gastrectomy + D2 lymph node dissection.Observation indicators:(1) surgery and postoperative recovery situations:surgical approach,overall operation time,hammer anvil placing time,esophagojejunal anastomosis time,volume of intraoperative blood loss,number of lymph node dissected,time to anal exsufflation,postoperative complications and duration of postoperative hospital stay;(2) postoperative pathological examination and chemotherapy;(3) follow-up and survival situations.Follow-up using telephone interview and outpatient examination was performed to detect tumor-free survival of patients up to April 2016.Measurement data with normal distribution were represented as x±s.The survival rate was calculated by the Kaplan-Meier method.Results (1) Surgery and postoperative recovery situations:all the 206 patients received successful operations,including 85 with abdominal operation,50 with abdominal incision through the diaphragmatic muscle into thoracic surgery and 71 with thoracic-abdominal surgery.Overall operation time,hammer anvil placing time,esophagojejunal anastomosis time,volume of intraoperative blood loss,number of lymph node dissected,time to anal exsufflation and duration of hospital stay were (113.7± 15.4)minutes,(3.5± 1.2)minutes,(10.4±2.9)minutes,(128±25) mL,32± 6,(2.4 ± 0.9) days and (12.3 ± 1.9) days,respectively.Of 206 patients,15 with postoperative complications were cured by conservative treatment,including 6 with implicit anastomotic fistula,3 with dominant anastomotic fistula,2 with pancreatic leakage,2 with intestinal obstruction,1 with anastomotic stenosis and 1 with thoracic and abdominal infection.There was no reoperation due to perioperative complications.(2) Postoperative pathological examination and chemotherapy:postoperative pathological results showed that distance from resection margin of the esophagus to tumor was (5.2±0.4) cm,without cancer cells in the resection margin.Among 206 patients,171 received postoperative chemotherapy by S1 single agent combined with oxaliplatin for 6-8 cycles or oral S1 single agent for 1 year.(3) Follow-up and survival situations:206 patients were followed up for (2.7± 0.3)years,with a tumor-free 3-year survival rate of 58％.During the follow-up,there was no recurrent anastomotic tumor.Conclusion The curved cutter stapler device combined with OrVil in the radical resection of Siewert type Ⅱ AEG can simplify the difficulty of esophagojejunal anastomosis and guarantee the safe resection margin of the lower esophagus.
ABSTRACT
The definition,staging and optimal treatment of adenocarcinoma of esophagogastric junction (AEG) have long been in controversy.Surgery is still the primary treatment for resectable AEG,and surgical procedures depend on its classifications.However,the efficacy of surgery alone is barely satisfactory.Neoadjuvant chemoradiotherapy and perioperative chemotherapy can improve the survival of patients.Simplified 2 cm principle is presented in the 8th edition of American Joint Committee on Cancer for TNM staging system of esophageal cancer.In addition,the new edition provides clinical staging and pathologic staging after neoadjuvant therapy,improving the clinical practicability of new staging system.
ABSTRACT
The incidence of adenocarcinoma of esophagogastric junction is increasing worldwide during recent decades.The therapeutic strategies have been transformed from surgery alone to multimodal treatments involing also perioperative chemoradiotherapy.Although there are still many problems on preoperative staging,surgical approach,excisional extent and perioperative chemoradiotherapy regimen,multidisciplinary team collaboration can provide an optimal diagnosis and treatment to achieve the principles of standardization and individualization in malignant tumor,which will prolong the survival and improve the quality of life for every patient.
ABSTRACT
The incidence of esophagogastric junction cancer (EGJC) is rising dramatically both in western countries and in China.For type Ⅱ EGJC,controversies over the optimal surgical approach still remain.More and more studies support the abdominal transhiatial extended gastrectomy to be superior to the abdominothoracic combined approach.The aim of this report is to evaluate the feasibility and safety of laparoscopic transabdominal hiatal extended gastrectomy for surgical treatment of type Ⅱ and Ⅲ esophagogastric junction cancer.Based on clinical experience of 95 patients who underwent laparoscopic tansabdominal hiatal extended gastrectomy,we conclude that laparoscopic transabdominal hiatal extended gastrectomy is feasible and safe,offering a safer and simpler way of intramediastinal dissection and digestive tract reconstruction at experienced hands as compared with open surgery.This procedure also offers the merit of longer esophageal resection length without entering the pleural cavity.
