RESUMEN

BACKGROUND: Our aim was to evaluate the influence of staged goal directed therapy (GDT) on postoperative pulmonary complications (PPCs), intraoperative hemodynamics and oxygenation in patients undergoing Mckeown esophagectomy. METHODS: Patients were randomly divided into three groups, staged GDT group (group A, n = 56): stroke volume variation (SVV) was set at 8-10% during the one lung ventilation (OLV) stage and 8-12% during the two lung ventilation (TLV) stage, GDT group (group B, n = 56): received GDT with a target SVV of 8-12% During the entire surgical procedure, and control group (group C, n = 56): conventional fluid therapy was administered by mean arterial pressure (MAP), central venous pressure (CVP), and urine volume. The primary outcome was the incidence of postoperative pulmonary complications within Postoperative days (POD) 7. The secondary outcomes were postoperative lung ultrasound (LUS) B-lines artefacts (BLA) scoring, incidence of other complications, the length of hospital stay, intraoperative hemodynamic and oxygenation indicators included mean arterial pressure (MAP), heart rate (HR), cardiac index (CI), cardiac output (CO), oxygenation index (OI), respiratory indices (RI), alveolar-arterial oxygen difference (Aa-DO2). RESULTS: Patients in group A and group B had a lower incidence of PPCs (7/56 vs. 17/56 and 9/56 vs. 17/56, p < 0.05), and a fewer B-lines score on postoperative ultrasound (4.61 ± 0.51 vs. 6.15 ± 0.74 and 4.75 ± 0.62 vs. 6.15 ± 0.74, p < 0.05) compared to group C. The CI, CO, MAP, and OI were higher in group A compared to group B and group C in the stage of thoracic operation. During the abdominal operation stage, patients in group A and group B had a better hemodynamic and oxygenation indicators than group C. CONCLUSIONS: In comparison to conventional fluid therapy, intraoperative staged GDT can significantly reduce the incidence of postoperative pulmonary complications in patients undergoing McKeown esophagectomy, facilitating patient recovery. Compared to GDT, it can improve intraoperative oxygenation and stabilize intraoperative hemodynamics in patients. TRIAL REGISTRATION: This study was registered in the Chinese Clinical Trial Registry on 24/11/2021 (ChiCTR2100053598).

RESUMEN

BACKGROUND: Second primary esophageal cancer often develops in patients with head and neck cancer, and esophagectomy in patients with a history of total pharyngolaryngectomy (TPL) is challenging. However, the clinical outcomes of these patients have yet to be examined in a multicenter setting. METHODS: We evaluated the surgical outcomes of a nationwide cohort of 62 patients who underwent esophagectomy for esophageal cancer with a history of TPL. RESULTS: Ivor-Lewis and McKeown esophagectomies were performed in 32 (51.6%) and 30 (48.4%) patients, respectively. Postoperatively, 23 patients (37.1%) developed severe complications, and 7 patients (11.3%) required reoperation within 30 days. Pneumonia and anastomotic leakage occurred in 13 (21.0%) and 16 (25.8%) patients, respectively. Anastomotic leakage occurred more frequently in the McKeown group than in the Ivor-Lewis group (46.7% vs. 6.2%, P < 0.001). The adjusted odds ratio for anastomotic leakage in the McKeown group was 9.64 (95% confidence intervals (CI), 2.11-70.82, P = 0.008). Meanwhile, the 5-year overall survival rates were comparable between the groups (41.8% for Ivor-Lewis and 42.7% for McKeown), and the adjusted hazard ratio of overall survival was 1.44 (95% CI, 0.64-3.29; P = 0.381; Ivor-Lewis as the reference). CONCLUSIONS: In our cohort, anastomotic leakage occurred more frequently after McKeown than Ivor-Lewis esophagectomy, and almost half of patients in the McKeown group experienced leakage. Ivor-Lewis esophagectomy is preferred for decreasing anastomotic leakage when oncologically and technically feasible.

RESUMEN

McKeown esophagectomy is a transthoracic esophagectomy with a cervical anastomosis that is an established mainstay for the management of benign and malignant esophageal pathology. It has gone through multiple modifications. The most current version utilizes robotic or minimally invasive ports through both the right chest and abdominal portions. There is decreased pain and hospital length of stay compared to the open technique. However, anastomotic leak and recurrent laryngeal nerve injury continue to occur. Advancements in management of complications has decreased mortality, making this surgical approach a relevant option for esophageal pathologies.

RESUMEN

BACKGROUND: The azygos lobe is a relatively rare anatomical variation, and there have been no reports, until date, of thoracoscopic McKeown esophagectomy for esophageal cancer in a patient with an azygos lobe. The azygos lobe can be diagnosed by chest X-ray or CT, and is usually not associated with any symptoms. However, surgeons should be aware that transthoracic surgical procedures in patients with an azygos lobe could be associated with a high risk of complications. CASE PRESENTATION: An 83-years-old man was brought to our emergency room with fever, severe headache, and difficulty in moving. MRI revealed a brain abscess, which was treated by abscess drainage and systemic antibiotic treatment. Further examinations to determine the cause of the brain abscess revealed esophageal cancer. In addition, CT revealed an azygos lobe in the right thoracic cavity. Although intrathoracic adhesions were anticipated on account of a previous history of bacterial pyothorax, we decided to perform esophagectomy via a thoracoscopic approach. Despite the difficulty in dissecting the intrathoracic adhesions, we were able to obtain the surgical field thoracoscopically. Then, we found the azygos lobe, as diagnosed preoperatively, and the azygos vein was supported by the mesentery draining into the superior vena cava. After dividing the mesentery, we clipped and cut the vessel, and both ends were further ligated. After these procedures, we safely performed esophagectomy with 3-field lymph node dissection. The postoperative course was uneventful, and the patient was discharged on the 21st postoperative day. CONCLUSIONS: Although there was a firm adhesion in the thoracic cavity, preoperative recognition of the azygos lobe could help in preventing intraoperative injury. Especially, esophageal surgeons are required to deal with the azygos lobe safely to avoid serious intraoperative injury.

RESUMEN

PURPOSE: Surgery for esophageal squamous cell carcinoma (ESCC) is characterized by a poor prognosis and high complication rate, resulting in a heavy symptom burden and poor health-related quality of life (QOL). We evaluated longitudinal patient-reported outcomes (PROs) to analyze the correlations between symptoms and QOL and their changing characteristics during postoperative rehabilitation. METHODS: We investigated patients with ESCC who underwent minimally invasive McKeown esophagectomy at Sichuan Cancer Hospital between April 2019 and December 2019. Longitudinal data of the clinical characteristics and PROs were collected. The MD Anderson Symptom Inventory and European Organization for Research and Treatment of Cancer (EORTC) QOL questionnaires were used to assess symptoms and QOL and compare the trajectories of PROs during the investigation. RESULTS: A total of 244 patients with ESCC were enrolled in this study. Regarding QOL, role and emotional functions returned to baseline at 1 month after surgery, and cognitive and social functions returned to baseline at 3 months after surgery. However, physical function and global QOL did not return to baseline at 1 year after surgery. At 7 days and 1, 3, 6, and 12 months after surgery, the main symptoms of the patients were negatively correlated with physical, role, emotional, cognitive, and social functions and the overall health status (P < 0.05). CONCLUSION: Patients with ESCC experience reduced health-related QOL and persisting symptoms after minimally invasive McKeown esophagectomy, but a recovery trend was observed within 1 month. The long-term QOL after esophagectomy is acceptable.

RESUMEN

Objective:To summarize and analyze the clinical outcome of minimally invasive McKeown esophagectomy for esophageal squamous cell carcinoma.Methods:We retrospectively analyzed the clinical data of patients with esophageal squamous cell carcinoma who received minimally invasive McKeown esophagectomy in Peking Union Medical College Hospital from January 2017 to December 2022. Improved anesthesia methods, monitoring of recurrent laryngeal nerve, minimally invasive gastrostomy, and jejunostomy techniques were introduced in surgical procedure. We evaluated perioperative data and long-term follow-up survival in these patients.Results:A total of 226 esophageal squamous cell carcinoma patients who met the inclusion and exclusion criteria were enrolled, of which 48.2% received neoadjuvant therapy. The mean operation time was( 327 ± 68) min, with a total of 40.5(33, 50) lymph nodes and 27(19, 33) thoracic lymph nodes harvested. The postoperative hospital stay was 9(7, 12) days, and the postoperative complication rate was 36.3%. In terms of learning curve, after 50 patients intraoperative blood loss, postoperative hospital stay, and recurrent laryngeal nerve injury rate were significantly decreased. The number of total lymph nodes, thoracic lymph nodes, and the 106tbl harvested was significantly increased. The median follow-up time was 23.5(14, 47) months, with a loss of follow-up rate of 3.5%. The overall 2-year and 5-year survival rates were 82.6% and 71.8%, respectively.Conclusion:Improved minimally invasive McKeown esophagectomy for esophageal squamous cell carcinoma are safe and acceptable. Learning curve can be shortened, with increased lymph node harvested and decreased postoperative complications, which improving the short-term and long-term outcomes of patients.

RESUMEN

Background: This study aimed to evaluate the short-term outcomes of enhanced recovery after surgery (ERAS) protocol in perioperative robotic-assisted McKeown esophagectomy (RAME) among esophageal cancer patients. Methods: For this retrospective study, all patients who had undergone RAME with esophageal cancer using ERAS protocol and conventional management strategy at the surgery center of our hospital from February 2019 to March 2022 were performed for analysis. Results: A total of 211 patients were included. Compared to the conventional group, the ERAS group has shorter median operative time [207 (147.5-267.5) vs. 244 (183-305), P<0.001], time to first flatus (P<0.001), time to out-of-bed activity (P=0.045), and time to liquid diet (P<0.001). In addition, the ERAS group has lower postoperative pain scores (3.62 ± 0.87 vs. 4.54 ± 0.91), shorter duration of analgesia pump [2 (1-3) vs. 3 (2.5-5.5)], shorter postoperative hospital stay [(9 (6-47) vs. 11 (6-79)], shorter postoperative hospital stay within neoadjuvant treated patients [8 (7-43) vs. 13 (8-67], shorter postoperative ICU stay [1 (0-7) vs. 2 (0-15)], and less reoperation rate (7.6% vs. 16.8%). Furthermore, the overall complication rate was significantly lower in the ERAS group (26.1%) than in the conventional group (50.4%). Notably, the ERAS group had lower thoracic fluid drainage volume than the conventional group on postoperative 2-7 days (P<0.05). Conclusions: The application of ERAS protocol in esophageal cancer patients treated with RAME showed advantages of quick postoperative recovery in contrast to the conventional management strategy.

RESUMEN

BACKGROUND: Thoracoscopic-assisted and robot-assisted Mckeown esophagectomy are currently two common surgical methods, but there is no clear statement on the advantages and disadvantages of the two. METHODS: This study conducted a single-centre retrospective analysis of esophageal cancer patients diagnosed and treated at Lanzhou University Second Hospital from 1 February 2020 to 31 July 2022. According to the inclusion and exclusion criteria, 126 patients were finally included in the RAM group and 169 patients in the TAM group. RESULTS: There was no significant difference between the RAM and TAM groups in the number of lymph node dissections, operative time, the length of stay in the intensive care unit after surgery, the incidence of hoarseness, postoperative pulmonary complications, surgery-related complications, use of opioids after surgery, the length of postoperative hospital stay, and 30-day mortality. CONCLUSIONS: RAM is a minimally invasive alternative to TAM and has similar short-term oncological efficacy.

RESUMEN

Anastomotic leakage is a life-threatening complication for esophageal cancer patients who received McKeown esophagectomy. Cervical drainage tube penetrating anastomosis is a rare but noteworthy cause of long-term nonunion of esophagogastric anastomosis. Here we reported two cases of esophageal cancer patients who received McKeown esophagectomy. The first case acquired the anastomotic leakage on postoperative day (POD) 7, and lasted for 56 days. The cervical drainage tube was removed at POD 38, and the leakage healed in 25 days. The second case acquired the anastomotic leakage on POD 8 and lasted for 95 days. The cervical drainage tube was removed at POD 57, and the leakage healed in 46 days. The two cases demonstrated the duration-prolonging effect of drainage tube penetrating anastomosis, which should not be overlooked in clinical practice. We suggested paying attention to the duration of leakage, the drainage fluids amounts and characteristics, and the imaging manifestations to help diagnose. If the cervical drainage tube penetrated the anastomosis, the tube should be eliminated as soon.

RESUMEN

BACKGROUND: As a novel alternative to the conventional minimally invasive esophagectomy (MIE) to treat esophageal cancer, single-port laparoscopic retrograde three-step gastric mobilization (SLRM) for esophageal reconstruction during MIE to treat esophageal cancer was attempted in our department. The aim of the present study was to explore the preliminary clinical outcomes and feasibility of this innovative surgery. METHODS: From March 2020 to November 2021, patients undergoing SLRM combined with four-port thoracoscopic McKeown esophagectomy for their esophageal cancers were reviewed. Gastric mobilization with abdominal lymph node dissection was performed through SLRM. The clinical characteristics and short-term outcomes were analyzed retrospectively. RESULTS: A total of 120 patients underwent R0 resection without conversion to open surgery. The mean times needed for the thoracic part, abdominal part, and total operation were 43 ± 6 min, 60 ± 18 min, and 230 ± 20 min, respectively. The numbers of mediastinal and abdominal lymph nodes harvested were 13.2 ± 2.7 and 10.2 ± 2.5, respectively. Postoperative pneumonia was encountered in 10 (8.3%) patients. Anastomotic leakage occurred in 3 (2.5%) cases. Temporary vocal cord paralysis was reported in 20 (16.6%) cases. The mean length of hospital stay was 8.5 ± 4.6 days. CONCLUSIONS: The SLRM is a technically feasible and safe treatment for patients with esophageal cancer. It can be considered an alternative method for patients, especially for the ones with obesity and gastric distension.

RESUMEN

Background: Till now there are very few reports about surgical results of Uniportal-VATS esophagectomy and no one about long-term outcomes. This study is the first comparing surgical and oncological outcomes of Uniportal-VATS with open McKeown esophagectomy, with the largest reported series and longest oncological follow-up. Methods: The prospectively collected clinical, surgical and oncological data of 75 patients, undergone McKeown esophagectomy at our Thoracic Surgery Department, from January 2012 to August 2022, were retrospectively analyzed. Nineteen patients underwent esophagectomy by thoracotomy and reconstruction according to McKeown technique while 56 by Uniportal-VATS approach. Gastric tubulization was performed totally laparoscopic or through a mini-laparatomic access and cervical anastomosis was made according to Orringer's technique. Results: The mean operative thoracic time was similar in both accesses (102.34 ± 15.21 min in Uniportal-VATS vs. 115.56 ± 23.12 min in open, p: 0.646), with a comparable number of mediastinal nodes retrieved (Uniportal-VATS:13.40 ± 8.12 vs. open:15.00 ± 6.86, p: 0.275). No case needed conversion from VATS to open. The learning curve in Uniportal-VATS was completed after 34 cases, while the Mastery was reached after 40. Both approaches were comparable in terms of minor post-operative complications (like pneumonia, lung atelectasis, anemization, atrial fibrillation, anastomotic-leak, left vocal cord palsy, chylothorax), while the number of re-operation for major complications (bleeding or mediastinitis) was higher in open group (21.0% vs. 3.6%, p: 0.04). Both techniques were also effective in terms of surgical radicality and local recurrence but VATS approach allowed a significantly lower chest tube length (11.89 ± 9.55 vs. 25.82 ± 24.37 days, p: 0.003) and post-operative stay (15.63 ± 11.69 vs. 25.53 ± 23.33, p: 0.018). The 30-day mortality for complications related to surgery was higher in open group (p: 0.002). The 2-, 5- and 8-year survival of the whole series was 72%, 50% and 33%, respectively. Combined 2- and 5-year OS in Uniportal-VATS group was 76% and 47% vs. 62% and 62% in open group, respectively (Log-rank, p: 0.286; Breslow-Wilcoxon: p: 0.036). No difference in DFS was recorded between the two approaches (5 year-DFS in Uniportal-VATS: 86% vs. 72%, p: 0.298). At multivariate analysis, only pathological stage independently affected OS (p: 0.02), not the surgical approach (p: 0.276). Conclusions: Uniportal-VATS seems to be a safe, feasible and effective technique for performing McKeown esophagectomy, with equivalent surgical and long-term oncological results to standard thoracotomy, but with a faster and unharmed recovery, and a quite short learning curve.

RESUMEN

It is unknown whether Ivor Lewis (IL) or McKeown (McK) esophagectomy is preferred in patients with potentially curable esophageal or gastro-esophageal junction (GEJ) cancer. Patients with mid- and distal esophageal and GEJ cancer without distant metastases who underwent IL or McK esophagectomy in the Netherlands between 2015 and 2017, were selected from the Netherlands Cancer Registry. Patients were propensity score matched for sex, age, American Society of Anesthesiologist classification, comorbidity, tumor type, tumor location, clinical stage, neoadjuvant treatment and year of diagnosis. The primary outcome was a 3-year relative survival (RS). Secondary outcome parameters were number of lymph nodes examined, number of positive lymph nodes, radical resection rate, tumor regression grade, post-operative complications and mortality. A total of 1627 patients who underwent IL (n = 1094) or McK (n = 533) esophagectomy were included. Patient and tumor characteristics were balanced after propensity score matching, leaving 658 patients to be compared. The 3-year RS was 54% after IL and 50% after McK esophagectomy, P = 0.140. The median number of lymph nodes examined, median number of positive lymph nodes, radical resection rate and tumor regression grade were comparable between both groups. Recurrent laryngeal nerve palsy (2 vs. 5%, P = 0.006) occurred less frequently after IL esophagectomy. No differences were observed in post-operative anastomotic leakage rate, pulmonary complication rate and mortality rates. There was no statistically significant difference in the 3-year RS between IL and McK esophagectomy. Based on these results, both IL and McK esophagectomy can be performed in patients with mid to distal esophageal and GEJ cancer.

RESUMEN

BACKGROUND: Postoperative complications related to gastric conduit reconstruction are still common issues after McKeown esophagectomy. A novel endoscopic mucosal ischemic index is desired to predict anastomotic complications after McKeown esophagectomy. AIMS AND METHODS: The purpose of this study was to prospectively evaluate the safety and efficacy of endoscopic examinations of the anastomotic region in the acute period after esophagectomy. Endoscopic examinations were performed on postoperative days (PODs) 1 and 8. The severity of ischemia was prospectively validated according to the endoscopic mucosal ischemic index (EMII). RESULTS: A total of 58 patients were included after evaluating the safety and feasibility of the endoscopic examination on POD 1 in 10 patients. Anastomotic leakage occurred in 6 patients. Stricture occurred in 13 patients. A greater than 67% circumference and lesion length greater than 20 mm of anastomotic ischemic area (AIA) on POD 1 were associated with developing anastomotic leakage after esophagectomy (OR: 14.5; 95% CI: 1.8-306.5; P = 0.03, OR: 19.4; 95% CI: 1.7-536.8; P = 0.03). More than 67% circumferential ischemic mucosa and ischemic mucosal lengths greater than 20 mm of AIA on POD 1 were associated with developing anastomotic strictures after esophagectomy (OR: 6.4; 95% CI: 1.4-31.7; P = 0.02, OR: 5.9; 95% CI: 1.2-33.1; P = 0.03). Patients with either more than 67% circumferential ischemic mucosa or ischemic mucosal lengths greater than 20 mm of AIA on POD 1 were defined as EMII-positive patients. The sensitivity, specificity, and positive and negative predictive values of EMII positivity on POD 1 for leakage were 100%, 78.8%, 35.3%, and 100%, respectively. The sensitivity, specificity, and positive and negative predictive values of the EMII positivity on POD 1 for strictures were 69.2%, 82.2%, 52.9%, and 90.2%, respectively. CONCLUSIONS: The application of an endoscopic classification system to mucosal ischemia after McKeown esophagectomy is both appropriate and satisfactory in predicting anastomotic complications.

RESUMEN

INTRODUCTION: Thoracic paravertebral block (TPVB) and subcostal transverse abdominis plane block (TAP) have been considered to provide an effective analgesic effect for laparoscopic and thoracoscopic surgery, respectively. The purpose of this randomized, controlled, and prospective study was to evaluate the analgesic effect of TPVB combined with TAP in patients undergoing total minimally invasive Mckeown esophagectomy. METHODS: Between February 2020 and December 2021, a total of 168 esophageal cancer patients undergoing McKeown esophagectomy at the Cancer Center of Sun Yat-Sen University, China, were randomly assigned to receive patient-controlled epidural analgesia alone (group PCEA, n = 56), patient-controlled intravenous analgesia alone (group PCIA, n = 56), and TPVB combined with TAP and patient-controlled intravenous analgesia (group PVB, n = 56). The primary outcome was a visual analogue scale (VAS) pain score on movement 48 h postoperatively. Secondary endpoints were pain scores at other points, intervention-related side effects, surgical complications, and length of intensive care unit and hospital stay. For the VAS pain score, the Kruskal-Wallis method was conducted for comparison of 3 treatment groups and further pairwise comparison with Bonferroni correction. RESULTS: On movement, the VAS in the PVB group was higher than that in the PCEA group at 48 h, 72 h, 96 h, and 120 h postoperatively (p < 0.05) except in the postoperative anesthesia care unit (PACU) and 24 h postoperatively. The VAS in the PCIA group was higher than the PCEA and PVB groups in the first 4 days after surgery. The pulmonary complication rate in the PCIA group was significantly higher than the rate in the PCEA [95% Confidence Interval 0.214 (0.354, 0.067), p = 0.024]. CONCLUSIONS: Combined TPVB and TAP was more effective than intravenous opioid analgesia alone, while PCEA was more effective than TPVB combined with TAP and intravenous opioid analgesia for patients after McKeown esophagectomy. TRIAL REGISTRATION: Chinese Clinical Trial Registry; ChiCTR2000029588.

RESUMEN

Objective:To investigate the surgical treatment and prognosis of thoracic esophageal squamous cell carcinoma (ESCC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 2 766 patients with thoracic ESCC who were admitted to Sichuan Cancer Hospital & Institute from January 2010 to December 2017 were collected. There were 2 256 males and 510 females, aged (62±8)years. All patients underwent surgical treatment. Observation indicators: (1) treatment; (2) postoperative complications; (3) postoperative survival. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represented as M( Q1, Q3). Count data were described as absolute numbers or percentages. The Kaplan-Meier method was used to draw survival curve and calculate survival rate, and the Log-Rank test was used for survival analysis. Result:(1) Treatment. Fifty-two of the 2 766 patients underwent neoadjuvant therapy. There were 1 444 patients undergoing open surgery, including 44 cases conversion to thoracotomy, and there were 1 322 patients undergoing minimally invasive esophagectomy. There were 1 991, 729 and 46 cases with McKeown, Ivor-Lewis and Sweet esophagectomy, respectively. One thousand two hundred and seventy-one of the 2 766 patients underwent postoperative adjuvant therapy. The number of lymph node metastases, the number of lymph node dissected, rate of R 0 resection, operation time of 2 766 patients were 2.1(0,3.0), 22±12, 94.722%(2 620/2 766), (237±66)minutes. (2) Postoperative complications. The overall incidence of postoperative complications was 25.850%(715/2 766). The top two postoperative complications were pneumonia and anastomotic fistula, with incidence rates of 8.604%(238/2766) and 7.484%(207/2766), respectively. One patient may have more than two kinds of postoperative complications. (3) Postoperative survival. The 1-, 3-and 5-year overall survival rates of 2 766 patients were 86.2%, 57.5% and 46.8%, respectively. Further analysis indicated that the 5-year overall survival rates of 510 female patients and 2 256 male patients were 62.0% and 43.3%, respectively, showing a significant difference between them ( χ2=48.94, P<0.05). The 5-year overall survival rates of 693 cases with upper thoracic ESCC, 1 479 cases with middle thoracic ESCC and 594 cases with lower thoracic ESCC were 49.5%, 46.7% and 44.1%, respectively, showing no significant difference among them ( χ2=3.21, P>0.05). The 5-year overall survival rates of 68 cases with stage 0 thoracic ESCC, 259 cases with stage Ⅰ esophageal ESCC, 885 cases with stage Ⅱ thoracic ESCC, 1 222 cases with stage Ⅲ thoracic ESCC, and 332 cases with stage Ⅳ thoracic ESCC were 95.6%, 76.4%, 61.4%, 35.6%, and 14.5%, respectively, showing a significant difference among them ( χ2=500.40, P<0.05). The 5-year overall survival rates of 1 444 patients undergoing open esophagectomy and 1 322 patients undergoing minimally invasive esophagectomy were 42.5% and 51.8%, respectively, showing a significant difference between them ( χ2=31.29, P<0.05). The 5-year overall survival rates of 1 991 cases undergoing McKeown esophagectomy, 729 cases undergoing Ivor-Lewis esophagectomy, and 46 cases undergoing Sweet esophagectomy were 49.5%, 41.2%, and 32.3%, respectively, showing a significant difference among them ( χ2=19.19, P<0.05). Conclusions:Compared with open esophagectomy, minimally invasive esophagectomy brings survival benefits to patients with thoracic esophageal ESCC. Among different esophagectomy methods, the McKeown esophagectomy has also brought survival benefits to patients with esophageal ESCC compared to the Ivor-Lewis esophagectomy and the Sweet esophagectomy.

Background: As a novel alternative to the conventional minimally invasive esophagectomy (MIE), more minimally invasive single-port laparoscopic retrograde 3-step gastric mobilization (SLRM) for esophageal reconstruction during MIE to treat esophageal cancer was attempted by our department. This study explored the preliminary clinical outcomes and feasibility of this innovative surgery. Methods: The data of 120 patients who had undergone SLRM combined with 4-port thoracoscopic McKeown esophagectomy for their esophageal cancers from March 2020 to November 2021 were reviewed. Gastric mobilization with abdominal lymph node dissection was performed via SLRM. The clinical characteristics and short-term outcomes were retrospectively analyzed. The data of operating time, blood loss, harvested lymph nodes, postoperative hospital stay and complications are presented as the mean and standard deviation. Results: A total of 120 patients underwent R0 resection without conversion to open surgery. The mean times for the thoracic procedure, abdominal procedure, and total operation were 43±6, 60±18, and 195±20 min, respectively. The numbers of mediastinal and abdominal lymph nodes harvested were 13.2±2.7, and 10.2±2.5, respectively. Postoperative pneumonia occurred in 10 patients (8.3%). Anastomotic leakage occurred in 3 patients (2.5%). Temporary vocal cord paralysis was reported in 20 patients (16.6%). The mean length of hospital stay was 8.5±4.6 days. Conclusions: SLRM is a technically feasible and safe treatment for patients with esophageal cancer. It can be considered an alternative method for patients, especially those with obesity and gastric distension.

RESUMEN

We aim to review the available literature on patients with esophageal cancer treated with robot-assisted (RAME) or video-assisted McKeown's esophagectomy (VAME), to compare the efficacy and safety of the two approaches. Original research studies that evaluated perioperative and oncologic outcomes of RAME versus VAME were identified, from January 1990 to July 2022. The 90-day mortality, the R0 resection rate, the dissected lymph nodes, the perioperative parameters, and the complications were calculated according to a fixed and a random effect model. The Q statistics and I2 statistic were used to test for heterogeneity among the studies. Seven studies were included, incorporating a total of 1617 patients treated with RAME or VAME. The 90-day mortality was similar between the two groups. No difference was found regarding the R0 resection rate and the number of dissected lymph nodes. In addition, the perioperative parameters, along with the total complications were similar between RAME and VAME. Nonetheless, the incidence of postoperative pneumonia was higher in the VAME group (OR:0.67 [95% CI: 0.49, 0.93]; p = 0.02). Finally, our outcomes were further validated by sensitivity analysis including only studies performing propensity score-matched analysis. Our meta-analysis showed that RAME was equivalent to VAME in terms of safety, feasibility, and oncologic adequacy. These results should be interpreted with caution due to the small number of included studies. New Randomized Controlled trials, that are currently active, will provide further evidence with greater clarity to assess the effectiveness and safety of RAME for esophageal cancer.

RESUMEN

Objective: To compare and analyze the perioperative clinical effects of minimally invasive Ivor-Lewis esophagectomy (MIE-Ivor-Lewis) and minimally invasive McKeown esophagectomy (MIE-McKeown). Methods: A total of 147 patients who underwent endoscopic esophageal cancer surgery from April 2018 to August 2019 were selected, including 85 patients undergoing MIE-McKeown surgery and 62 patients undergoing MIE-Ivor-Lewis surgery. The measurement data were expressed as (x±s), the comparison of normally distributed measurement data was performed by independent sample t-test, and the comparison of count data was performed by χ(2) test or Fisher's exact test. Results: The operation time of McKeown (M) group and Ivor-Lewis (IL) group were (219.2±72.4) minutes and (225.8±65.3) minutes. The mediastinal lymph node dissection number of M and IL groups were 13.3±4.8 and 11.6±6.5, respectively. The number of left recurrent laryngeal nerve lymph node dissection were 3.5±1.2 and 3.1±1.4, respectively. The intraoperative blood loss were (178.3±41.3) ml and (163.2±64.1) ml, respectively. The number of patients reoperated for postoperative bleeding were 1 and 0, respectively. The number of patients with postoperative gastric bleeding were 0 and 1, respectively. The postoperative chest tube retention time were (2.8±1.3) days and (3.1±1.2) days, respectively. The number of patients with anastomotic leakage were 7 and 1, respectively. The number of patients with lung infection were 13 and 5, respectively, and with chylothorax were 2 and 1, respectively, without statistically significant difference (P>0.05). The number of patients with hoarseness were 11 and 3, respectively. The total incidence of complication were 41.2% (35/85) and 17.7% (11/62), and the postoperative hospital stay were (14.7±6.5) days and (12.3±2.3) days, with statistical difference (P<0.05). Conclusion: MIE-Ivor-Lewis and MIE-McKeown are safe and effective in treating esophageal cancer, but the complication of MIE-Ivor-Lewis is less than that of MIE-Mckeown, and the perioperative clinical effect of MIE-Ivor-Lewis is better than that of MIE-McKeown.

RESUMEN

Objectives: Even underwent radical resection, some patients of thoracic esophageal squamous cell carcinoma (ESCC) are still exposed to local recurrence in a short time. To this end, the present study sought to differentiate patient subgroups by assessing risk factors for postoperative early (within one year) local lymph node recurrence (PELLNR). Methods: ESCC patients were selected from a prospective database, and divided into high- and low-risk groups according to the time of their local lymphatic recurrence (within one year or later). Survival analysis was conducted by the Cox regression model to evaluate the overall survival (OS) between the two groups. The hazard ratio (HR) and 95% confidence interval (CI) of different variables were also calculated. Logistic regression analysis was used to explore the high-risk factors for PELLNR with the odds ratio (OR) and 95% CI calculated. Results: A total of 432 cases were included. The survival of patients in the high-risk group (n = 47) was significantly inferior to the low-risk group (n = 385) (HR = 11.331, 95% CI: 6.870-16.688, P < 0.001). The 1-year, 3-year, and 5-year OS rate of the patients in high/low-risk groups were 74.5% vs. 100%, 17% vs. 88.8%, and 11.3% vs. 79.2%, respectively (P < 0.001). Risk factors for local lymph node recurrence within one year included upper thoracic location (OR = 4.071, 95% CI: 1.499-11.055, P = 0.006), advanced T staging (pT3-4, OR = 3.258, 95% CI: 1.547-6.861, P = 0.002), advanced N staging (pN2-3, OR = 5.195, 95% CI: 2.269-11.894, P < 0.001), and neoadjuvant treatment (OR = 3.609, 95% CI: 1.716-7.589, P = 0.001). In neoadjuvant therapy subgroup, high-risk group still had unfavorable survival (Log-rank P < 0.001). Multivariate analysis demonstrated that upper thoracic location (OR = 5.064, 95% CI: 1.485-17.261, P = 0.010) and advanced N staging (pN2-3) (OR = 5.999, 95% CI: 1.986-18.115, P = 0.001) were independent risk factors for early local lymphatic recurrence. However, the cT downstaging (OR = 0.862, 95% CI: 0.241-3.086, P = 0.819) and cN downstaging (OR = 0.937, 95% CI: 0.372-2.360, P = 0.890) for patients in the neoadjuvant subgroup failed to lower PELLNR. The predominant recurrence field type was single-field. Conclusions: Thoracic ESCC patients with lymph node recurrence within one year delivered poor outcomes, with advanced stages (pT3-4/pN2-3) and upper thoracic location considered risk factors for early recurrence.
