Feasibility of utilizing mediastinal drains alone following esophageal cancer surgery: a retrospective study.

BACKGROUND: It was typically necessary to place a closed thoracic drainage tube for drainage following esophageal cancer surgery. Recently, the extra use of thoracic mediastinal drainage after esophageal cancer surgery had also become more common. However, it had not yet been determined whether mediastinal drains could be used alone following esophageal cancer surgery. METHODS: A total of 134 patients who underwent esophageal cancer surgery in our department between June 2020 and June 2023 were retrospectively analyzed. Among them, 34 patients received closed thoracic drainage (CTD), 58 patients received closed thoracic drainage combined with mediastinal drainage (CTD-MD), while 42 patients received postoperative mediastinal drainage (MD). The general condition, incidence of postoperative pulmonary complications, postoperative NRS score, and postoperative anastomotic leakage were compared. The Mann-Whitney U tests, Welch's t tests, one-way ANOVA, chi-square tests and Fisher's exact tests were applied. RESULTS: There was no significant difference in the incidence of postoperative hyperthermia, peak leukocytes, total drainage, hospitalization days and postoperative pulmonary complications between MD group and the other two groups. Interestingly, patients in the MD group experienced significantly lower postoperative pain compared to the other two groups. Additionally, abnormal postoperative drainage fluid could be detected early in this group. Furthermore, there was no significant change in the incidence of postoperative anastomotic leakage and the mortality rate of patients after the occurrence of anastomotic leakage in the MD group compared with the other two groups. CONCLUSIONS: Using mediastinal drain alone following esophageal cancer surgery was equally safe. Furthermore, it could substantially decrease postoperative pain, potentially replacing the closed thoracic drain in clinical practice.

Comparison of neoadjuvant chemotherapy or chemoradiotherapy plus immunotherapy for locally resectable esophageal squamous cell carcinoma.

Background: Neoadjuvant chemotherapy plus immunotherapy (nCT + ICIs) and neoadjuvant chemoradiotherapy plus immunotherapy (nCRT + ICIs) both induced favorable pathological response and tolerant toxicities for locally resectable esophageal squamous cell carcinoma (ESCC). However, few studies compared safety and efficacy between the two treatment strategies. Methods: This retrospective study collected clinical data of locally resectable ESCC patients who underwent nCT + ICIs or nCRT + ICIs followed by esophagectomy from November 2019 to December 2022. The incidence of adverse events, surgical outcomes, short and long-term efficacy, and treatment costs were compared. Results: A total of 206 patients were included, with a ratio of 158:48 between nCT + ICIs group and nCRT + ICIs group. The two groups exhibited well-balanced baseline characteristics. Most adverse events were grade 1-2 in both groups. The nCT + ICIs group had a longer operative time (334.00 ± 170.2 min vs 279.60 ± 88.31 min, P=0.020) than nCRT + ICIs group, but there were no differences in surgical complications. Although nCT + ICIs group had a lower pCR rate (32.3% vs 52.1%, P=0.004), the 2-year overall survival (84.42% vs 81.70%, P=0.860), 2-year disease-free survival (83.21% vs 80.47%, P=0.839), and recurrence patterns were similar to nCRT + ICIs group. In addition, nCT + ICIs group had significantly lower expenses (188796.00 ± 107704.00 RMB vs 231808.00 ± 48067.00 RMB, P=0.045). Conclusion: Overall, nCT + ICIs have comparable safety and efficacy compared to nCRT + ICIs for locally resectable ESCC, but with lower hospitalization costs.

Premature mortality for patients after completely resected early adenocarcinoma of the esophagus or stomach.

OBJECTIVE: To establish the life expectancy burden of esophago-gastric cancer by analyzing years of life lost (YLL) for a Western patient population after treatment of early esophageal (EAC) or early gastric (GAC) adenocarcinoma. BACKGROUND: For patients with early EAC or GAC, the short-term prognosis after surgical resection is very good. Little data is available regarding long-term prognosis when compared to the general population. METHODS: Two hundred and fourteen patients with pT1 EAC (n = 112) or GAC (n = 102) were included in the study. Patients with EAC underwent transthoracic en-bloc esophagectomy; those with GAC had total or subtotal gastrectomy with D2-lymphadenectomy. Surviving patients had a median follow-up of approximately 14 years. YLL was calculated using average life expectancy data from Germany. RESULTS: Patients with EAC were younger (median age 61 years) than those with GAC (66 years) (p = 0.031). The male:female ratio was 10:1 for EAC and 3:2 for GAC (p < 0.001). Multivariate survival analysis showed the age of the patients ≥60 years and the existence of lymph node metastasis was associated with poor prognosis. The median YLL for all patients who died over follow-up was 8.0 years. For patients under 60 years, it was approximately 20 years, and for older patients, approximately 5 years (p < 0.001) without difference in tumor stage between these age cohorts. YLL did not differ for GAC vs. EAC. CONCLUSION: After surgical resection, the prognostic burden as measured by YLL is relevant for all patients with early esophageal and gastric adenocarcinomas and especially for younger patients. Reasons for YLL need further studies.

Exploration of lymph node recurrence patterns and delineation guidelines of radiation field in middle thoracic oesophageal carcinomas after radical surgery: a real-world study.

BACKGROUND: Oesophageal squamous cell carcinoma is one of the most commonly diagnosed carcinomas in China, and postoperative radiotherapy plays an important role in improving the prognosis of patients. Carcinomas in different locations of the oesophagus could have different patterns of lymph node metastasis after surgery. METHODS: In this multicentric retrospective study, we enrolled patients with middle thoracic oesophageal squamous cell carcinomas from 3 cancer centres, and none of the patients underwent radiotherapy before or after surgery. We analysed the lymph node recurrence rates in different stations to explore the postoperative lymphatic recurrence pattern. RESULTS: From January 1st, 2014, to December 31st, 2019, 132 patients met the criteria, and were included in this study. The lymphatic recurrence rate was 62.1%. Pathological stage (P = 0.032) and lymphadenectomy method (P = 0.006) were significant predictive factors of lymph node recurrence. The recurrence rates in the supraclavicular, upper and lower paratracheal stations of lymph nodes were 32.6%, 28.8% and 16.7%, respectively, showing a high incidence. The recurrence rate of the subcarinal node station was 9.8%, while 8.3% (upper, middle and lower) thoracic para-oesophageal nodes had recurrences. CONCLUSIONS: We recommend including the supraclavicular, upper and lower paratracheal stations of lymph nodes in the postoperative radiation field in middle thoracic oesophageal carcinomas. Subcarinal station is also potentially high-risk, while whether to include thoracic para-oesophageal or abdominal nodes needs careful consideration.

Pathological response to neoadjuvant chemoradiotherapy for oesophageal squamous cell carcinoma in Eastern versus Western countries: meta-analysis.

OBJECTIVE: Locally advanced oesophageal squamous cell carcinoma can be treated with neoadjuvant chemoradiotherapy or chemotherapy followed by oesophagectomy. Discrepancies in pathological response rates have been reported between studies from Eastern versus Western countries. The aim of this study was to compare the pathological response to neoadjuvant chemoradiotherapy in Eastern versus Western countries. METHODS: Databases were searched until November 2022 for studies reporting pCR rates after neoadjuvant chemoradiotherapy for oesophageal squamous cell carcinoma. Multi-level meta-analyses were performed to pool pCR rates separately for cohorts from studies performed in centres in the Sinosphere (East) or in Europe and the Anglosphere (West). RESULTS: For neoadjuvant chemoradiotherapy, 51 Eastern cohorts (5636 patients) and 20 Western cohorts (3039 patients) were included. Studies from Eastern countries included more men, younger patients, more proximal tumours, and more cT4 and cN+ disease. Patients in the West were more often treated with high-dose radiotherapy, whereas patients in the East were more often treated with a platinum + fluoropyrimidine regimen. The pooled pCR rate after neoadjuvant chemoradiotherapy was 31.7% (95% c.i. 29.5% to 34.1%) in Eastern cohorts versus 40.4% (95% c.i. 35.0% to 45.9%) in Western cohorts (fixed-effect P = 0.003). For cohorts with similar cTNM stages, pooled pCR rates for the East and the West were 32.5% and 41.9% respectively (fixed-effect P = 0.003). CONCLUSION: The pathological response to neoadjuvant chemoradiotherapy is less favourable in patients treated in Eastern countries compared with Western countries. Despite efforts to investigate accounting factors, the discrepancy in pCR rate cannot be entirely explained by differences in patient, tumour, or treatment characteristics.

Impact of change in the Naples prognostic score after neoadjuvant chemoradiotherapy on survival in esophageal squamous cell carcinoma patients.

OBJECTIVES: To assess the clinical relevance and prognostic value of changes in the Naples prognostic score (NPS) after neoadjuvant chemoradiotherapy (NACR) among esophageal squamous cell carcinoma (ESCC) patients. METHODS: We studied 232 locally advanced ESCC patients who received NACR before undergoing esophagectomy retrospectively. Categorizing individuals into the elevated NPS group and the non-elevated NPS group based on the change in NPS after NACR (ΔNPS > 0 or ∆NPS ≤ 0), we examined and compared the clinicopathological characteristics, survival rates, and postoperative complications between these 2 groups (∆NPS = post-NACR NPS - pre-NACR NPS). RESULTS: Results: Out of the 232 patients enrolled, 105 exhibited elevated NPS levels, while 127 showed non-elevated NPS levels. Survival analyses indicated inferior overall survival (OS) (p=0.024) and recurrence-free survival (RFS) (p=0.047) in the elevated NPS cohort compared to the non-elevated NPS cohort. Subsequent cox regression analyses identified the post-NACR change in NPS as an independent prognostic indicator for RFS (p=0.029) and OS (p=0.036). CONCLUSION: Elevated NPS post-NACR emerged as a significant indicator of worse prognosis for locally advanced ESCC patients who underwent NACR. This finding has great potential to be useful for recognizing high-risk ESCC patients who received NACR before undergoing esophagectomy and making individualized subsequent therapeutic decisions in clinical practice.

Novel reconstruction using pedicled ileocolic interposition with intrathoracic esophago-ileal anastomosis after distal esophagectomy for esophagogastric junction cancer: A report of two cases.

There is no optimal reconstruction after radical distal esophagectomy for cancers of the esophagogastric junction. We designed a novel reconstruction technique using pedicled ileocolic interposition with intrathoracic anastomosis between the esophagus and the elevated ileum. Two patients underwent the surgery. Case 1 was a 70-year-old man with esophagogastric junction adenocarcinoma with 3 cm of esophageal invasion. Case 2 was a 70-year-old man with squamous cell carcinoma of the esophagogastric junction; the epicenter of which was located just at the junction. These two patients underwent radical distal esophagectomy and pedicled ileocolic interposition with intrathoracic anastomosis. They were discharged on postoperative days 17 and 14, respectively, with no major complication. Pedicled ileocolic interposition is characterized by sufficient elevation and perfusion of the ileum, which is fed by the ileocolic artery and vein. As a result, we can generally adapt this reconstruction method to most curable esophagogastric junction cancers.

Successful chimney endovascular aortic repair with reconstruction of three visceral branches for huge saccular juxtarenal abdominal aortic aneurysm after trans-thoracoabdominal esophagectomy.

BACKGROUND: Conventional graft replacement for a juxtarenal abdominal aortic aneurysm (JRAAA) remains challenging for high-risk patients since it often requires the reconstruction of some visceral arteries. CASE PRESENTATION: A 76-year-old woman was diagnosed with an 87 × 48 mm saccular JRAAA. Open graft replacement was contraindicated because of frailty and a past history of trans-thoracoabdominal esophagectomy. Chimney endovascular aortic repair (ChEVAR) with three chimney endografts was successfully performed without any endoleaks, and each visceral circulation was kept intact. The patient was discharged uneventfully on postoperative day 8. Significant shrinkage of the aneurysmal sac and preservation of flow through each chimney graft were observed on computed tomography 6 months postoperatively, with no significant increase in serum creatinine levels on laboratory testing. CONCLUSIONS: ChEVAR can be a useful surgical option instead of conventional operations, especially for high-risk cases.

Robot-assisted oesophagectomy (Ivor-Lewis) for a complex stenosis previously managed by open gastrostomy tube placement.

A man in his late 50s presented with severe dysphagia caused by a complex refractory benign stenosis that was completely obstructing the middle oesophagus. The patient was unsatisfied with the gastrostomy tube placed via laparotomy as a long-term solution. Therefore, we performed robot-assisted minimally invasive oesophagectomy (video). Mobilisation of the stomach and gastric conduit preparation were more difficult due to the previously inserted gastrostomy tube; thus, the conduit blood supply was assessed using indocyanine green fluorescence. After an uncomplicated course, the patient was referred directly to inpatient rehabilitation on the 16th postoperative day. At 9 months after surgery, the motivated patient returned to full-time work and achieved level 7 on the functional oral intake scale (total oral diet, with no restrictions). At the 1-year follow-up, he positively confirmed all nine key elements of a good quality of life after oesophagectomy.

Early postoperative systemic inflammatory response as predictor of anastomotic leakage after esophagectomy: a systematic review and meta-analysis.

BACKGROUND AND PURPOSE: Postesophagectomy anastomotic leakage occurs in up to 16% of patients and is the main cause of morbidity and mortality. The leak severity is determined by the extent of contamination and the degree of sepsis, both of which are related to the time from onset to treatment. Early prediction based on inflammatory biomarkers such as C-reactive protein (CRP) levels, white blood cell counts, albumin levels, and combined Noble-Underwood (NUn) scores can guide early management. This review aimed to determine the diagnostic accuracy of these biomarkers. METHODS: This study was designed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and registered in the PROSPERO (International Prospective Register of Systematic Reviews) database. Two reviewers independently conducted searches across PubMed, MEDLINE, Web of Science, and Embase. Sources of bias were assessed, and a meta-analysis was performed. RESULTS: Data from 5348 patients were analyzed, and 13% experienced leakage. The diagnostic accuracy of the serum biomarkers was analyzed, and pooled cutoff values were identified. CRP levels were found to have good diagnostic accuracy on days 2 to 5. The best discrimination was identified on day 2 for a cutoff value < 222 mg/L (area under the curve = 0.824, sensitivity = 81%, specificity = 88%, positive predictive value = 38.6%, and negative predictive value = 98%). A NUn score of >10 on day 4 correlated with poor diagnostic accuracy. CONCLUSION: The NUn score failed to achieve adequate accuracy. CRP seems to be the only valuable biomarker and is a negative predictor of postesophagectomy leakage. Patients with a CRP concentration of <222 mg/L on day 2 are unlikely to develop a leak, and patients can safely proceed through their enhanced recovery after surgery protocol. Patients with a CRP concentration of <127 mg/L on day 5 can be safely discharged when clinically possible.

Nutritional responsiveness affects novel neutrophil parameters and reduces in-hospital mortality and costs in elective cancer oesophagectomy - a single centre, prospective, observational study.

INTRODUCTION: Malnutrition in surgical patients remains a common issue affecting the perioperative period. Oesophageal cancer is a disease associated with one of the highest malnutrition rates. Assessment of patient nutritional status remains a challenge due to limited validated tools. Novel parameters to identify malnourished patients and the effectiveness of preoperative nutritional intervention might improve treatment results in the perioperative period. MATERIAL AND METHODS: This was a prospective, observational, single-centre study of patients scheduled for elective oesophagectomy. The primary aim of this study was to establish the correlation between neutrophil reactivity intensity (NEUT-RI) and neutrophil granularity intensity (NEUT-GI) and patients' nutritional status. We divided patients into nutritional responders (R group) and nutritional non-responders (NR group) defined as regaining at least 25% of the maximum preoperative body weight loss during the preoperative period. RESULTS: The R group had significantly shorter intensive care unit (ICU) stays: 5.5 (4-8) vs. 13 (7-31) days ( P = 0.01). It resulted in a lower cost of ICU stays in the R group: 4775.2 (3938.9-7640.7) vs. 12255.8 (7787.6-49108.7) euro in the NR group ( P = 0.01). Between the R group and the NR group, we observed statistically significant differences in both preoperative NEUT-RI (48.6 vs. 53.4, P = 0.03) and NEUT-GI (154.6 vs. 159.3, P = 0.02). Apart from the T grade, the only preoperative factor associated with reduced mortality was the nutritional responsiveness: 11.1% vs. 71.4% ( P = 0.008). CONCLUSIONS: Preoperative nutritional responsiveness affects neutrophil intensity indexes and reduces in-hospital mortality and costs associated with hospital stay. Further research is required to determine the correlation between novel neutrophil parameters and patients' nutritional status.

Association between preoperative anxiety states and postoperative complications in patients with esophageal cancer and COPD: a retrospective cohort study.

BACKGROUND: Esophageal cancer brings emotional changes, especially anxiety to patients. Co-existing anxiety makes the surgery difficult and may cause complications. This study aims to evaluate effects of anxiety in postoperative complications of esophageal cancer patients with chronic obstructive pulmonary disease (COPD). METHODS: Patients with esophageal cancer and co-existing COPD underwent tumor excision. Anxiety was measured using Hospital Anxiety and Depression Scale (HAD) before surgery. Clavien-Dindo criteria were used to grade surgical complications. A multiple regression model was used to analyze the relationship between anxiety and postoperative complications. The chi-square test was used to compare the differences in various types of complications between the anxiety group and the non-anxiety group. A multinomial logistic regression model was used to analyze the influencing factors of mild and severe complications. RESULTS: This study included a total of 270 eligible patients, of which 20.7% had anxiety symptoms and 56.6% experienced postoperative complications. After evaluation by univariate analysis and multivariate logistic regression models, the risk of developing complications in anxious patients was 4.1 times than non-anxious patients. Anxious patients were more likely to develop pneumonia, pyloric obstruction, and arrhythmia. The presence of anxiety, surgical method, higher body mass index (BMI), and lower preoperative oxygen pressure may increase the incidence of minor complications. The use of surgical methods, higher COPD assessment test (CAT) scores, and higher BMI may increase the incidence of major complications, while anxiety does not affect the occurrence of major complications (P = 0.054). CONCLUSION: Preoperative anxiety is associated with postoperative complications in esophageal cancer patients with co-existing COPD. Anxiety may increase the incidence of postoperative complications, especially minor complications in patient with COPD and esophageal cancer.

Surgical vs nonsurgical treatment for esophageal squamous cell carcinoma in patients older than 70 years: a propensity score matching analysis.

PURPOSE: With the rising life expectancy and an aging population, it has become increasingly important to investigate treatments suitable for older adult patients with esophageal cancer. This study investigated whether older adult patients who underwent esophagectomy had better clinical outcomes than those who were nonsurgically treated. METHODS: We retrospectively analyzed patients with esophageal squamous cell carcinoma (ESCC) who were 70 years or older and underwent esophagectomy, radiotherapy (RT), and/or chemoradiotherapy (CRT) between January 2018 and December 2019. Patients were divided into 2 groups: the surgery group (S group) and the nonsurgery group (NS group). We then compared the clinical outcomes of the 2 groups. RESULTS: After a median follow-up duration of 36.6 months, the S group showed better overall survival (OS). The 3-year OS was 59% in the S group and 27% in the NS group (hazard ratio [HR], 0.397; 95% CI, 0.278-0.549; P < .0001). In the S group, the median progression-free survival was 38.3 months (95% CI, 30.6-46.1) compared with 12.3 months in the NS group (HR, 0.511; 95% CI, 0.376-0.695; P < .0001). In addition, the number of adverse events in the NS group was higher than that in the S group (P < .001). CONCLUSION: Overall, patients with ESCC at the age of ≥70 years who underwent esophagectomy had significantly better clinical outcomes than those who underwent nonsurgical treatment with RT and/or CRT.

Contemporary outcomes for resected type 1-3 gastroesophageal junction adenocarcinoma: a single-center experience.

BACKGROUND: Surgical resection remains the mainstay of treatment for tumors of the gastroesophageal junction (GEJ). However, contemporary analyses of the Western experience for GEJ adenocarcinoma are sparsely reported. METHODS: Patients with GEJ adenocarcinoma undergoing resection between 2012 and 2022 at a single institution were grouped based on Siewert subtype and analyzed. Pathologic and treatment related variables were assessed with relation to outcomes. RESULTS: A total of 302 patients underwent resection: 161 (53.3%) with type I, 116 (38.4%) with type II, and 25 (8.3%) with type III tumors. Most patients received neoadjuvant therapy (86.4%); 86% of cases were performed in a minimally invasive fashion. Anastomotic leak occurred in 6.0% and 30-day mortality in only 0.7%. The rate of grade 3+ morbidity was lower for the last 5 years of the study than for the first 5 years (27.5% vs 49.3%, P < .001), as was median length of stay (7 vs 8 days, P < .001). There was a significantly greater number of signet ring type tumors among type III tumors (44.0%) than type I/II tumors (11.2/12.9%, P < .001). Otherwise, there was no difference in the distribution of pathologic features among Siewert subtypes. Notably, there was a significant difference in 3-year overall survival based on Siewert classification: type I 60.0%, type II 77.2%, and type III 86.3% (P = .011). Siewert type I remained independently associated with worse survival on multivariable analysis (hazard ratio, 4.5; P = .023). CONCLUSIONS: In this large, single-institutional series, operative outcomes for patients with resected GEJ adenocarcinoma improved over time. On multivariable analysis, type I tumors were an independent predictor of poor survival.

Robot-Assisted-Minimally Invasive-Transhiatal Esophagectomy (RAMI-THE).

The authors review the development and steps of the robotic-assisted minimally invasive transhiatal esophagectomy. Key goals of the robot-assisted approach have been to address some of the concerns raised about the technical challenges with the traditional open transhiatal esophagectomy while keeping most of the steps consistent with the open approach.

Minimally Invasive Modified McKeown Esophagectomy.

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.

Conduit Selection for Reconstruction After Esophagectomy for Esophageal Cancer.

The reconstruction of the esophagus after esophagectomy presents many technical and management challenges to surgeons. An effective gastrointestinal conduit that replaces the resected esophagus must have adequate length to reach the upper thoracic space or the neck, have robust vascular perfusion, and provide sufficient function for an adequate swallowing mechanism. The stomach is currently the preferred conduit for esophageal reconstruction after esophagectomy. However, there are circumstances, where the stomach cannot be utilized as a conduit. In these cases, an alternative conduit must be considered. The current alternative conduits include colon, jejunum, and tubed skin flaps.

Management of Major Complications After Esophagectomy.

Esophagectomy remains a procedure with one of the highest complication rates. Given the advances in medical and surgical management of patients and increased patient survival, the number of complications reported has increased. There are different grading systems for complications which vary based on severity or organ system, with the Esophageal Complications Consensus Group unifying them. Management involves conservative intervention and dietary modification to endoscopic interventions and surgical reintervention. Treatment is etiology specific but rehabilitation and patient optimization play a significant role in managing these complications by preventing them. Management is a step-up approach depending on the severity of symptoms.

Robotic-Assisted Ivor Lewis Esophagectomy.

Robotic-assisted surgery is a safe and effective approach to minimally invasive Ivor Lewis esophagectomy. Outcomes are optimized when surgeons are familiar with the fundamentals of minimally invasive surgery of the esophagus and after gaining sufficient experience with robotic surgical techniques.

Minimally Invasive Ivor Lewis Esophagectomy.

Minimally invasive Ivor Lewis esophagectomy is a technically demanding operation that requires an experienced surgeon, assistant, and anesthesiologist. The preoperative workup should focus on the extent of disease and extent of resection required, as well as the cardiopulmonary fitness of the patient. Surgical outcomes show decreased postoperative pain, decreased morbidity largely due to a reduction in respiratory complications, and decreased length of stay. Quality metrics and 5-year overall survival are equivalent to traditional open esophagectomy.
