Comparison of short-term outcomes and three yearsurvival between total minimally invasive McKeown and dual-incision esophagectomy

The Role of Ultrasound-Guided Multipoint Fascial Plane Block in ElderlyPatients Undergoing Combined Thoracoscopic-Laparoscopic Esophagectomy: A Prospective Randomized Study

INTRODUCTION

We estimated the safety and efficacy of ultrasound-guided multipoint fascial plane block, including serratus anterior plane block (SAPB) and bilateral transversus abdominis plane block (TAPB) in elderly patients who underwent combined thoracoscopic-laparoscopic esophagectomy (TLE).

METHODS

The authors enrolled 80 patients in this prospective study after patient selection using the inclusion and exclusion criteria who were scheduled for elective TLE from May 2020 to May 2021. Patients were randomly assigned to the treated group (group N) or the control group (group C) (n = 40 per group) using the sealed-envelope method. Multipoint fascial plane blocks, including serratus anterior plane block (SAPB) and bilateral TAPB, were performed on patients undergoing TLE using a solution of 60 mL 0.375% ropivacaine plus 2.5 mg dexamethasone by 3 injections of 20 mL each (group N) or no interventions (group C).

RESULTS

Systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) at T incision and 30 min after T incision were significantly higher in group C than in group N, and also significantly higher than at baseline (P < 0.01). Blood glucose at 60 min, 2 h after T incision, was significantly higher in group C than in group N and significantly higher than at baseline (P < 0.01). Compared to group N, the dosages of propofol and remifentanil used during surgery in group C were more than those in group N (P < 0.01). The time to first rescue analgesic in group C was earlier than in group N. The total postoperative use of sufentanil, and the number of patients requiring rescue analgesics in group C, were more than in group N (P < 0.01).

CONCLUSIONS

This study showed that applying the multipoint fascia pane block technique in TLE for elderly patients could significantly reduce postoperative pain, decrease the dosages of drugs used in general anesthesia, improve the quality of the awakening, and have no obvious adverse reactions.

Minimally Invasive or Open Esophagectomy for Treatment of Resectable Esophageal Squamous Cell Carcinoma? Answer From a Real-world Multicenter Study

OBJECTIVE

To evaluate the long-term and short-term outcomes of MIE compared with OE in localized ESCC patients in real-world settings.

BACKGROUND

MIE is an alternative to OE, despite the limited evidence regarding its effect on long-term survival.

METHODS

We recruited 5822 consecutive patients with resectable ESCC in 2 typical high-volume centers in southern and northern China, 1453 of whom underwent MIE. Propensity score-based overlap weighted regression adjusted for multifaceted confounding factors was used to compare outcomes in the MIE and OE groups.

RESULTS

Five-year OS was 62.7% in the MIE group and 57.7% in the OE group. The overlap weighted Cox regression showed slightly better OS in the MIE group (hazard ratio 0.93, 95% confidence interval: 0.82-1.06). Although duration of surgery was longer and treatment cost higher in the MIE group than in the OE group, the number of lymph nodes harvested was larger, the proportion of intraoperative blood transfusions lower, and postoperative complications less in the MIE group. 30-day (risk ratio [RR] 0.77, 0.381.55) and 90-day (RR 0.79, 0.46-1.35) mortality were lower in the MIE group versus the OE group, although not statistically significant. These findings were consistent across different analytic approaches and subgroups, notably in the subset of ESCC patients with large tumors.

CONCLUSIONS

MIE can be performed safely with OS comparable to OE for patients with localized ESCC, indicating MIE may be recommended as the primary surgical approach for resectable ESCC in health facilities with requisite technical capacity.

Efficacy of sternocleidomastoid muscle flap in reducing anastomotic mediastinal/pleural cavity leak

BACKGROUND

Anastomotic mediastinal/pleural cavity leak (AMPCL) is a life-threatening postoperative complication after esophagectomy. The objective of this study was to find a safe and effective surgical method to reduce the incidence of AMPCL.

METHODS

A total of 223 patients who underwent surgery in Fujian Medical University Union Hospital from May 2020 to October 2021 were enrolled in this study. Data for preoperative and postoperative test indices, postoperative complications, perioperative treatment were collected. After using 1:1 propensity score matching (PSM) to match two cohort (caliper = 0.1), the relationship between various factors and the incidence of AMPCL were analyzed.

RESULTS

209 patients were included for further analysis in the end. There were 95 patients in the sternocleidomastoid muscle flap embedding group (intervention group) and 114 in the routine operation group (control group). There was a significant difference in mean age between two groups. Gender, age, body mass index, diabetes, American society of anesthesiologists score, preoperative neoadjuvant therapy, pathological stage were included in performing 1:1 PSM, and there were no significant differences between two groups. Median operative time was significantly less in intervention group. Anastomotic leak (AL) did not present significant difference between two groups (8 [8.6] vs. 13 [14.0], p = 0.247), however, the AMPCL in intervention group was significantly lower than control group (0 [0] vs. 6 [6.5], p = 0.029).

CONCLUSIONS

The sternocleidomastoid muscle flap embedding could significantly reduce the incidence of AMPCL. This additional procedure is safe, and effective without increase in the occurrence of postoperative complications and hospital expenses.

A New Esophagogastric Anastomosis for McKeown Esophagectomy in Esophageal Cancer

For McKeown esophagectomy, hand-sewn and mechanical esophagogastric anastomosis techniques have been improved for constructing esophagogastrostomy. However, postoperative anastomosis-related complication rates remain high in patients undergoing cervical anastomosis. Here, we report an original and reliable hand-sewn cervical tunnel esophagogastric anastomosis technique to maximally reduce cervical anastomotic leakage and stricture rates after McKeown esophagectomy. The key features and innovations of cervical tunnel esophagogastric anastomosis are the right gastroepiploic artery as the center for the esophagogastric anastomosis to reduce ischemia, sufficient width of the anastomotic site for anastomosis without stricture, enfolding of the anastomotic site by the tunnel, and tension- and rotation-free anastomosis.

Minimally invasive esophagectomy via Sweet approach in combination with cervical mediastinoscopy is a valuable approach for surgical treatment of esophageal cancer

OBJECTIVES

To compare the short-, mid-, and long-term outcomes in patients with esophageal cancer between minimally invasive esophagectomy via Sweet approach in combination with cervical mediastinoscopy (MIE-SM) and minimally invasive esophagectomy via McKeown approach (MIE-MC), and to evaluate the value of MIE-SM in the surgical treatment of esophageal cancer.

METHODS

A prospective, nonrandomized study was adopted. A total of 65 esophageal cancer patients after MIE-SM and MIE-MC from June 2014 to May 2016 were included. Among them, 33 patients underwent MIE-SM and 32 patients underwent MIE-MC. Short-term outcomes (including the duration of surgery, intraoperative blood loss volume, ICU stay time, postoperative complications, postoperative hospital stay, reoperation, open surgery, number of dissected lymph nodes, and 30-day mortality), mid-term outcomes, [including Quality of Life Core Questionnaire (QLQ-C30) and the esophageal site-specific module (QLQ-OES18)], long-term outcomes [including overall survival and disease-free survival] were compared between the 2 groups.

RESULTS

Radical resection (R0) were achieved in all patients. There were no significant differences in the duration of surgery, intraoperative blood loss volume, ICU stay time, postoperative complications, and postoperative hospital stay between the 2 groups (all P>0.05). More lymph nodes were dissected in the MIE-SM group (24.1±7.3) than those in the MIE-MC group (17.8±5.0, P<0.001). The emotional function, global health status scale scores in QLQ-C30 scale in the MIE-SM group were significantly higher than those in the MIE-MC group (P=0.025, P<0.001, respectively), and the pain score in the MIE-SM group was significantly lower than that in the MIE-MC group (P=0.013). QLQ-OES18 results showed that the pain score in the MIE-SM group was significantly lower than that in the MIE-MC group (P=0.021). Survival analysis showed that the overall survival and disease-free survival were similar between the 2 groups.

CONCLUSIONS

MIE-SM appears to be a safe surgical approach, which may get better quality of life, suffer less pain, and can achieve the same therapeutic effect as MIE-MC. Therefore, MIE-SM should be considered as a valuable approach for the treatment of middle and lower esophageal cancer.

Minimally invasive techniques for transthoracic oesophagectomy for oesophageal cancer: systematic review and network meta-analysis

BACKGROUND

Oesophagectomy is a demanding operation that can be performed by different approaches including open surgery or a combination of minimal access techniques. This systematic review and network meta-analysis aimed to evaluate the clinical outcomes of open, minimally invasive and robotic oesophagectomy techniques for oesophageal cancer.

METHODS

A systematic literature search was conducted for studies reporting open oesophagectomy, laparoscopically assisted oesophagectomy (LAO), thoracoscopically assisted oesophagectomy (TAO), totally minimally invasive oesophagectomy (MIO) or robotic MIO (RAMIO) for oesophagectomy. A network meta-analysis of intraoperative (operating time, blood loss), postoperative (overall complications, anastomotic leaks, chyle leak, duration of hospital stay) and oncological (R0 resection, lymphadenectomy) outcomes, and survival was performed.

RESULTS

Ninety-eight studies involving 32 315 patients were included in the network meta-analysis (open 17 824, 55·2 per cent; LAO 1576, 4·9 per cent; TAO 2421 7·5 per cent; MIO 9558, 29·6 per cent; RAMIO 917, 2·8 per cent). Compared with open oesophagectomy, both MIO and RAMIO were associated with less blood loss, significantly lower rates of pulmonary complications, shorter duration of stay and higher lymph node yield. There were no significant differences between surgical techniques in surgical-site infections, chyle leak, and 30- and 90-day mortality. MIO and RAMIO had better 1- and 5-year survival rates respectively compared with open surgery.

CONCLUSION

Minimally invasive and robotic techniques for oesophagectomy are associated with reduced perioperative morbidity and duration of hospital stay, with no compromise of oncological outcomes but no improvement in perioperative mortality.

Major Postoperative Complications in Esophageal Cancer After Minimally Invasive Esophagectomy Compared With Open Esophagectomy: An Updated Meta-analysis

BACKGROUND

To evaluate the existing literature comparing cardiopulmonary complications after minimally invasive esophagectomy (MIE) with open esophagectomy (OE) and conduct a meta-analysis based on the relevant studies.

METHODS

A systematic search for articles was performed in Medline, Embase, Wiley Online Library, and the Cochrane Library. The relative risks or odds ratios (ORs) were calculated by using fixed or random-effects models. The I² and X² tests were used to test for statistical heterogeneity. We performed a metaregression for the pulmonary complications with the adenocarcinoma proportion and tumor stage. Publication bias and small-study effects were assessed using Egger's test and Begg's funnel plot.

RESULTS

A total of 30,850 participants were enrolled in the 63 studies evaluated in the meta-analysis. Arrhythmia, pulmonary embolism, pulmonary complications, gastric tip necrosis, anastomotic leakage, and vocal cord palsy were chosen as outcomes. The occurrence rate of arrhythmia was significantly lower in patients receiving MIE than in patients receiving OE (OR = 0.69; 95% CI = 0.53-0.89), with heterogeneity (I² = 30.7%, P = 0.067). The incidence of pulmonary complications was significantly lower in patients receiving MIE (OR = 0.54, 95% CI = 0.45-0.63) but heterogeneity remained (I² = 72.1%, P = 0.000). The risk of gastric tip necrosis (OR = 1.48, 95% CI = 1.07-2.05) after OE was lower than that after MIE. Anastomotic leakage, pulmonary embolism, and vocal cord palsy showed no significant differences between the two groups.

CONCLUSIONS

MIE has advantages over OE, especially in reducing the incidence of arrhythmia and pulmonary complications. Thus, MIE can be recommended as the preferred alternative surgery method for resectable esophageal cancer.

Comparison of short-term outcomes following minimally invasive versus open Sweet esophagectomy for Siewert type II adenocarcinoma of the esophagogastric junction

Background

Surgical resection is still the main treatment option for patients with resectable Siewert type II adenocarcinoma of the esophagogastric junction (AEG). This retrospective study evaluated the significance of minimally invasive Sweet esophagectomy (MISE) for the treatment of Siewert type II AEG.

Methods

We retrospectively evaluated 174 patients with Siewert type II AEG who received a Sweet esophagectomy in our center between October 2013 and September 2017. Of these patients, 73 underwent MISE and 101 underwent open Sweet esophagectomy (OSE). The clinicopathologic factors, operational factors and postoperative complications were compared.

Results

The two groups were similar in terms of age, sex, American Society of Anesthesiologists grade, preoperative staging and incidence of comorbidities (P > 0.05). Relative to the OSE approach, the MISE approach was associated with a significant decrease in surgical blood loss (P < 0.001), chest tube duration (P = 0.003) and postoperative admission duration (P = 0.002). The minimally invasive approach was associated with significantly less total morbidity and fewer respiratory complications than the open approach (P = 0.015 and P = 0.016, respectively). Relative to the open approach, the MISE approach was associated with a significant increase in the number of total lymph nodes removed and the locations of the total lymph nodes removed (P < 0.001 and P < 0.001, respectively).

Conclusions

Our MISE technique can be safely and effectively performed for intrathoracic anastomosis with favorable early outcomes.

Minimally Invasive Esophagectomy: A Consensus Statement

BACKGROUND

Minimally invasive esophagectomy (MIE) is increasingly performed in various ways. The lack of international definitions and nomenclature makes accurate comparison of outcomes difficult.

METHODS

An international, multispecialty consensus-writing committee constructed definitions and nomenclature for MIE. After a PubMed search, vetting, and review with all authors, a consensus was reached.

RESULTS

The proposed definition for MIE is an operation "that removes part or all of the esophagus, does not retract, lift, spread or remove any part of the chest or abdominal wall and the surgeon's and assistant's vision of the operative field is via a monitor, the patient's tissue is manipulated only by instruments that are controlled by the operating surgeon or team, except for during the neck portion if used." A flexible nomenclature is proposed that attempts to describe current and future operations and systems.

CONCLUSIONS

Definitions and nomenclature for MIE are needed to ensure that future studies accurately compare results and outcomes of similar operations. Nomenclatures allow surgeons, researchers, and patients from different cultures to use a common language to facilitate communication and compare. This process is required in order to improve patient outcomes globally to drive adoption of best of practice, yet is lacking for MIE.

Mapping patterns of metastatic lymph nodes for postoperative radiotherapy in thoracic esophageal squamous cell carcinoma: a recommendation for clinical target volume definition

Background

The clinical target volume (CTV) for postoperative radiotherapy for thoracic esophageal squamous cell carcinoma (TESCC) needs to be defined. The study aim was to map metastatic lymph nodes (LNMs) in a computed tomography (CT)-based atlas and delineate the postoperative radiotherapy target area.

Methods

Sixty-nine TESCC patients with first recurrent regional LNMs after esophagectomy were included. The LNM epicenters were registered onto corresponding anatomic axial CT images of a standard patient in the treatment position, with reference to the surrounding vascular and bony structures. The LNM sites were based on lymph node map of esophageal cancer, AJCC 8th. The lymph metastasis risk for different segments of thoracic esophagus was assessed.

Results

One hundred and seventy-nine LNMs were mapped onto standard axial CT images. The upper-middle mediastinum region (station 1 to 8 M) contained 97% of metastases in the upper segment of thoracic esophagus, 90% in the middle segment, and 66% in the lower one. Advanced pathological stage (≥IIIB) might be a predictive factor for upper abdominal region (UAR) relapse in lower TESCC. Lower cervical para-tracheal LNMs were within a 4.3-cm bilaterally expanded area from the midline of the body and a 2.2-cm expanded area from the anterior of vertebral body, from the superior border of the C7, to the inferior border of the first thoracic vertebra.

Conclusion

A modified target from the upper border of C7 to the lower border of caudal margin of the inferior pulmonary vein level could cover the high-risk area of TESCC underwent postoperative radiotherapy. UAR seems to be an elective irradiation target for lower TESCC at pathological IIIB stage and higher.

A new technology for reducing anastomotic fistula in the neck after esophageal cancer surgery

Background

To explore the risk factors and prevention methods of cervical mechanical anastomotic fistula and stenosis after the radical resection of esophageal cancer.

Methods

From March 2018 to November 2018, 128 patients undergoing mechanical anastomosis of esophageal cancer were selected from the Department of Thoracic Surgery of The First Affiliated Hospital of Zhengzhou University. All the enrolled patients were operated on using the Mckeown method, and a retrospective study was conducted. Data for preoperative and postoperative test indices, intraoperative embedding materials, postoperative complications, and preoperative and postoperative treatment were collected, and the relationship between various factors and the incidence of cervical anastomotic fistula and stenosis was analysed. Univariate analysis was conducted using t tests or Fisher's exact probability method, and multivariate analysis was conducted using logistic regression models.

Results

All 128 patients successfully underwent surgery without dying. The enrolled patients were evaluated using the Stooler classification, with 28 patients having grade 0, 41 patients having grade 1, 34 patients having grade 2, 21 patients having grade 3, and 4 patients having grade 4 stenosis. Patients with stenosis of grade 3 or above had obvious choking sensation, which could only be relieved by balloon dilation. Symptoms in all patients with stenosis were relieved by balloon dilation. There were no significant differences between the two groups regarding embedding materials, preoperative choking history, history of alcohol consumption, history of hypertension, history of coronary heart disease, history of diabetes, postoperative calcium concentration, average albumin concentration, average platelet concentration, body mass index, anastomotic fistula, preoperative chemotherapy, postoperative chemotherapy, or postoperative cough (P>0.05). There were significant differences in postoperative reflux (χ²=11.338, P<0.05) and scar constitution (χ²=12.497, P<0.05). The effects of embedding materials in patients with anastomotic fistula were significantly different (χ²=4.372, P<0.05).

Conclusions

Postoperative reflux and scar constitution may be risk factors for postoperative anastomotic stenosis after resection of esophageal cancer. There was almost no difference in the effects on esophageal anastomotic stenosis between embedding materials and the omentum majus, but Neoveil^® may have certain advantages in preventing cervical anastomotic fistula, and thus may have certain clinical application value.

Synchronous carcinoma of oesophageal and lung treated with laparoscopic-thoracoscopic cooperative surgery: A case report

Traditional open surgery has been used and was regarded as suitable alternatives to synchronous carcinoma of oesophageal and lung. However, few previous reports described laparoscopic-thoracoscopic cooperative surgery for it. In this present case, we report synchronous carcinoma of oesophageal and lung with laparoscopic-thoracoscopic cooperative surgery, showing new successfully approach treated with minimally invasive laparoscopic-thoracoscopic surgery.

Value of the preoperative neutrophil-to-lymphocyte ratio as a prognostic factor for long-term survival in postoperative esophageal squamous cell carcinoma patients

BACKGROUND

This study investigated the relationship between the neutrophil-to-lymphocyte ratio (NLR) and clinicopathological features and prognosis in patients with postoperative esophageal squamous cell carcinoma (ESCC).

METHODS

The preoperative NLR was evaluated in 419 patients who underwent esophagectomy for ESCC. A receiver operating characteristic (ROC) curve was plotted to verify the accuracy of the NLR for predicting survival. Correlation between the NLR and clinicopathological characteristics was analyzed using the χ2 test. Prognostic influence was calculated by using the Kaplan-Meier method and the difference was assessed by log-rank test. Multivariate Cox regression models were applied to evaluate the independent prognostic value.

RESULTS

The cutoff value of the NLR was 2.998, the area under the curve was 0.735, and the sensitivity and specificity were 69.3% and 69.3%, respectively. Tumor length (P = 0.0317), lymph node metastasis (P = 0.0352), pathological tumor node metastasis (pTNM) stage (P = 0.0271), and postoperative radiotherapy (P = 0.0385) were significantly different between the groups. Multivariate analysis showed that pTNM stage (P = 0.0098), lymph node metastasis (P = 0.001), and NLR (P = 0.0022) were independent prognostic factors for survival. Moreover, when patients were stratified by TNM stage, the adverse effects of preoperative NLR on cancer-specific survival were greater in patients with stage II and III ESCC and in patients with lymph node metastasis.

CONCLUSIONS

The preoperative NLR is significantly correlated with long-term prognosis in postoperative patients with ESCC, particularly in patients with lymph node metastasis and stage II and III ESCC.

Left minimally invasive esophagectomy in a patient with synchronous esophageal and lung cancers: Case report

RATIONALE

Minimally invasive esophagectomy (MIE) have been increasingly used and are regarded as suitable alternatives to open esophagectomy. However, few previous reports described minimally invasive esophagectomy using a left-sided approach.

PATIENT CONCERNS AND DIAGNOSES

A 71-year-old man was admitted to our hospital because of progressive dysphagia. Synchronous double primary thoracic esophageal and left lung cancers were considered before the operation.

INTERVENTIONS AND OUTCOMES

A lobectomy and MIE, via a left video-assisted thoracoscopic approach, was performed. Preparation of a gastric conduit and an intra-abdominal lymphadenectomy were completed by laparoscopy and a cervical anastomosis was made. In addition, a cervical mediastinoscopy was performed to dissect the lymph nodes along the bilateral recurrent laryngeal nerves. No postoperative complications were observed. The patient achieved a favorable short-term outcome.

LESSONS

This is the first report of a patient with synchronous esophageal and left lung cancers treated with minimally invasive resection via left thoracoscopy, laparoscopy, and cervical mediastinoscopy. Our results showed that the left MIE approach in combination with cervical mediastinoscopy is potentially most appropriate for some esophageal cancer patients, when the right MIE approach is not applicable in certain conditions.
