RESUMO
BACKGROUND: Minimally invasive esophagectomy (MIE) has been increasingly performed for locally advanced esophageal cancer in place of open transthoracic esophagectomy (OE). This study explored the significance of MIE for esophageal squamous cell carcinoma (ESCC), focusing mainly on the depth of primary esophageal tumors. METHODS: This study retrospectively assessed short- and long-term outcomes of patients who underwent esophagectomy for ESCC from 2005 through 2021. The inverse probability of the treatment-weighting (IPTW) method was used to compare the outcomes between OE and MIE. The outcomes also were evaluated in the subgroups stratified by cT category. RESULTS: Among 1117 patients, 447 (40%) underwent OE and 670 (60%) underwent MIE. After IPTW adjustment, the incidence of any postoperative complications was significantly higher in the OE group than in the MIE group (60.8% vs 53.7%; p = 0.032), whereas the R0 resection rate was significantly higher in the MIE group (98.6% vs 92.7%; p < 0.001). The MIE group showed better 3 year overall and cancer-specific survival than the OE group (p < 0.001). The incidence of locoregional recurrence within the surgical field was significantly more frequent in the OE group (p < 0.001). In the subgroup analysis stratified by cT category, the R0 resection rate was significantly higher and the incidence of locoregional recurrence was lower in the MIE group among the patients with cT3-4 tumors. In the patients with cT1-2 tumors, MIE showed no significant benefit over OE. CONCLUSIONS: For the patients with cT3-4 tumors, MIE showed fewer postoperative complications, better locoregional control, and better prognosis than OE. Compared with OE, MIE is beneficial, especially for locally advanced ESCC.

BACKGROUND: Robotic surgical systems with full articulation of instruments, tremor filtering, and motion scaling can potentially overcome the procedural difficulties in endoscopic surgeries. However, whether robot-assisted minimally invasive esophagectomy (RAMIE) can overcome anatomical difficulties during thoracoscopic esophagectomy remains unclear. This study aimed to clarify the anatomical and clinical factors that influence the difficulty of RAMIE in the thoracic region. METHODS: Forty-five patients who underwent curative-intent RAMIE with upper mediastinal lymph node dissection for esophageal cancer were included. Using preoperative computed tomography images, we calculated previously reported anatomical indices to assess the upper mediastinal narrowness and vertebral body projections in the middle thoracic region. The factors influencing thoracic operative time were then investigated. RESULTS: During the thoracic procedure, the median operative time was 215 (124-367) min and the median blood loss was 20 (5-190) mL. Postoperatively, pneumonia, anastomotic leakage, and recurrent laryngeal nerve palsy occurred in 17.8%, 2.2%, and 6.7% of the patients, respectively. The multiple linear regression model revealed that a narrow upper mediastinum and greater blood loss during the thoracic procedure were significant factors associated with a prolonged thoracic operative time (P = 0.025 and P < 0.001, respectively). Upper mediastinal narrowing was not associated with postoperative complications. CONCLUSIONS: A narrow upper mediastinum was significantly associated with a prolonged thoracic operative time in patients with RAMIE.

A high risk of complications still accompanies gastric conduit reconstruction after esophagectomy. In this narrative review, we summarize the technological progress and the problems of gastric conduit reconstruction after esophagectomy. Several types of gastric conduits exist, including the whole stomach and the narrow gastric tube. The clinical outcomes are similar between the two types of conduits. Sufficient blood supply to the conduit is mandatory for a successful esophageal reconstruction. Recently, due to the availability of equipment and its convenience, indocyanine green angiography has been rapidly spreading. When the blood perfusion of the planning anastomotic site is insufficient, several techniques, such as the Kocher maneuver, pedunculated gastric tube with duodenal transection, and additional microvascular anastomosis, exist to decrease the risk of anastomotic failure. There are two different anastomotic sites, cervical and thoracic, and mainly two reconstructive routes, retrosternal and posterior mediastinal routes. Meta-analyses showed no significant difference in outcomes between the anastomotic sites as well as the reconstructive routes. Anastomotic techniques include hand-sewn, circular, and linear stapling. Anastomoses using linear stapling is advantageous in decreasing anastomosis-related complications. Arteriosclerosis and poorly controlled diabetes are the risk factors for anastomotic leakage, while a narrow upper mediastinal space and a damaged stomach predict leakage. Although standardization among the institutional team members is essential to decrease anastomotic complications, surgeons should learn several technical options for predictable or unpredictable intraoperative situations.
RESUMO
BACKGROUND: Periodontitis is a biofilm-associated inflammatory periodontal disease associated with postoperative complications after esophagectomy. However, few studies have evaluated the inflammatory burden posed by periodontitis quantitively for patients undergoing oncologic esophagectomy. This study aimed to clarify the relationship between periodontitis and postoperative pneumonia using periodontal inflammatory surface area (PISA). METHODS: The study analyzed 251 patients who underwent esophagectomy for esophageal cancer. The patients were classified into low-PISA and high-PISA groups according to preoperative PISA, and the relationship between the occurrence and severity of postoperative pneumonia was investigated. RESULTS: The high-PISA group (n = 69) included more males (P < 0.001) and patients with poor performance status (P < 0.024). Postoperative pneumonia occurred more frequently in the high-PISA group than in the low-PISA group (31.9 % vs. 15.9 %; P = 0.008), whereas the incidences of other complications did not differ significantly. In addition, the incidence of severe pneumonia was significantly higher in the high-PISA group (7.2 % vs. 1.6 %; P = 0.038). In the multivariable analysis for adjustment of preoperative confounders, age older than 70 years (odds ratio [OR], 2.62; P = 0.006), high PISA (OR, 2.45; P = 0.012), and smoking history (OR, 2.78; P = 0.006) were the independent variables predicting postoperative pneumonia. CONCLUSION: Preoperative higher PISA was significantly associated with the occurrence of overall and severe postoperative pneumonia. The quantitative evaluation of periodontitis using PISA is a useful measure for predicting postoperative pneumonia, and intensive periodontal intervention may contribute to decreasing postoperative pneumonia.

BACKGROUND: Oncologic esophagectomy in patients with a history of total pharyngolaryngectomy (TPL) is challenging. There are two different esophagectomy procedures: total esophagectomy with cervical anastomosis (McKeown) and subtotal esophagectomy with intrathoracic anastomosis (Ivor-Lewis). Differences in outcomes between McKeown and Ivor-Lewis esophagectomies for patients with this history remain unclear. METHODS: We retrospectively reviewed 36 patients with a history of TPL who underwent oncologic esophagectomy and compared the clinical outcomes between the procedures. RESULTS: Twelve (33.3%) and 24 (66.7%) patients underwent McKeown and Ivor-Lewis esophagectomies, respectively. McKeown esophagectomy was more frequently performed for the supracarinal tumors (P = 0.002). Other baseline characteristics, including the history of radiation therapy, were comparable between the groups. Postoperatively, the incidences of pneumonia and anastomotic leakage were higher in the McKeown group than in the Ivor-Lewis group (P = 0.029 and P < 0.001, respectively). Neither tracheal necrosis nor remnant esophageal necrosis was observed. The overall and recurrence-free survival rates were comparable between the groups (P = 0.494 and P = 0.813, respectively). CONCLUSIONS: When performing esophagectomy for patients with a history of TPL, if it is oncologically acceptable and technically available, Ivor-Lewis is preferable over McKeown esophagectomy for avoiding postoperative complications.

PURPOSE: Recent reports have suggested that basophils influence allergic reactions and tumor immunity. In this study, we aimed to elucidate the association between preoperative circulating basophil (CB) counts and the outcomes of patients who underwent esophagectomy for esophageal cancer. METHODS: A total of 783 consecutive patients who underwent esophagectomy for esophageal cancer were eligible. The clinicopathological factors and prognoses were compared between the groups stratified by the preoperative counts of CB. RESULTS: There were more advanced clinical T and N stages in the low CB group than in the high CB group (P = 0.01 and = 0.04, respectively). The incidences of postoperative complications were comparable between the groups. The low CB count was associated with unfavorable overall and recurrence-free survivals (P = 0.04 and 0.01, respectively). In the multivariate analysis, low CB count was one of the independent prognostic factors for poor recurrence-free survival (HR 1.33; 95% CI 1.04-1.70; P = 0.02). In addition, hematogenous recurrence occurred more frequently in the low CB group than in the high CB group (57.6% vs. 41.4%, P = 0.04). CONCLUSION: A preoperative low CB count was an unfavorable prognosticator in patients who underwent esophagectomy for esophageal cancer.

BACKGROUND: Although accumulating evidence suggests that an imbalanced gut microbiota leads to cancer progression, few studies demonstrated the implication in patients who underwent oncologic esophagectomy. This study aimed to elucidate the association between gut microbes and the outcomes after oncologic esophagectomy, as well as the host's inflammatory/nutritional status. METHODS: Overall, 783 consecutive patients who underwent oncologic esophagectomy were eligible. We investigated the microbiota detected by fecal culture tests and then assessed the association between the gut microbiota and patient characteristics, short-term outcomes, and long-term survival. RESULTS: Seventeen different species could be cultivated. We comprehensively examined the impact of each detected microbe on survival. The presence of Bacillus species (Bacillus sp.; 26.8%) was associated with favorable prognosis on overall and cancer-specific survival (p = 0.02 and 0.02, respectively). Conversely, the presence of Proteus mirabilis (P. mirabilis; 3.4%) was associated with unfavorable overall and recurrence-free survivals (p = 0.02 and < 0.01, respectively). Multivariate analysis showed that the presence of P. mirabilis was one of the independent prognostic factors for poor recurrence-free survival (p < 0.01). Patients with Bacillus sp. had lower modified Glasgow prognostic score and better response to preoperative treatment than those without (p = 0.01 and 0.03, respectively). Meanwhile, patients with P. mirabilis were significantly associated with higher systemic inflammation scores and increased postoperative pneumonia incidence than those without (p = 0.01 and 0.02, respectively). CONCLUSIONS: Preoperative fecal microbiota was associated with the host's inflammatory and nutritional status and may influence the outcomes after oncologic esophagectomy.

BACKGROUND: McKeown esophagectomy with two-field lymphadenectomy is the treatment of choice for oncologic esophagectomy. A cervical drain is placed in cases after modern two-field lymph node dissection (M2FD) to provide information on anastomotic leakage. However, the necessity of prophylactic cervical drainage during surgery remains unknown. This study aimed to clarify the clinical significance of cervical drainage in patients who underwent McKeown esophagectomy with M2FD. METHODS: A total of 293 patients underwent McKeown surgery with two-field lymphadenectomy at our institute between January 2013 and December 2019. We compared the day of drain removal, amount of drainage volume, and the appearance of drainage fluid between patients with and without anastomotic leakage. RESULTS: McKeown esophagectomy reconstructed through the retrosternal route is 203 patients (69.3%) of all. Nineteen patients (6.5%) experienced anastomotic leakage. The amount of cervical drain discharge was comparable between patients with and without anastomotic leakage. In addition, no purulent or salivary discharge was observed in patients with anastomotic leakage. There was no difference in the median day of drain removal between the groups. The initial clinical findings for the diagnosis of anastomotic leakage were surgical site infection in 10 (52.6%), fever in 5 (26.3%), prolonged inflammation in a blood test in 3 (15.8%), and bloody discharge from the chest tube in 1 (5.3%). There was no mortality due to any cause. CONCLUSION: A prophylactic cervical drain may not be mandatory in patients with esophageal cancer undergoing McKeown esophagectomy reconstructed through the retrosternal route with two-field lymphadenectomy.

PURPOSE: Although C-reactive protein to prealbumin ratio (CPR) can predict the outcomes of several types of cancer surgeries, little is known about the implication of CPR in patients undergoing esophagectomy for esophageal squamous cell carcinoma (ESCC). METHODS: Between 2009 and 2018, 682 consecutive ESCC patients who underwent curative esophagectomy were enrolled. The clinicopathological factors and prognoses were compared between the groups stratified by preoperative CPR levels. A logistic regression model was used to determine the risk factors of postoperative pneumonia. Survival curves were constructed using the Kaplan-Meier method and compared using the log-rank test. The Cox proportional hazards model was used to elucidate prognostic factors. RESULTS: There were more elderly patients, more males, and more advanced clinical T and N categories in the high CPR group than in the low CPR group. Also, the incidence of postoperative pneumonia was significantly higher in the high CPR group than in the low CPR group (32.4% vs. 20.3%, p < 0.01). In multivariate analyses, high CPR was one of the independent predictive factors for postoperative pneumonia (OR, 1.71; 95% CI, 1.15-2.54; p < 0.03). Moreover, high CPR was an independent prognostic factor for overall, cancer-specific, and recurrence-free survivals (HR 1.62; 95% CI 1.18-2.23; p < 0.01, HR 1.57; 95% CI 1.08-2.32; p = 0.02, HR 1.42; 95% CI 1.06-1.90; p = 0.02). CONCLUSION: Preoperative CPR was found to be a useful inflammatory and nutritional indicator for predicting the occurrence of pneumonia and prognosis in patients with ESCC undergoing esophagectomy.

BACKGROUND: Patients with esophageal cancer are at a high risk of malnutrition after esophagectomy, and nutritional support may at times be required for several months following surgery. In this study, we aimed to clarify the clinical features and preoperative risk factors of patients with long-term insufficiency of oral intake after esophagectomy by evaluating the duration of feeding enterostomy placement. METHODS: A total of 306 patients who underwent esophagectomy, reconstruction with gastric conduit, and feeding enterostomy creation were retrospectively reviewed. We analyzed the clinical features and preoperative risk factors for long-term placement of feeding enterostomy. RESULTS: The feeding enterostomy tube was removed less than 90 days after esophagectomy in 234 patients (76.5%) (short group), whereas 72 patients still needed enteral nutrition after 90 days (23.5%; long group). Although severe malnutrition was observed more frequently in the long group compared with the short group (p = 0.021), overall survival time was comparable between the groups (p = 0.239). Multivariate analysis revealed that higher age (odds ratio [OR] 1.04; 95% confidence interval [CI], 1.01-1.07; p = 0.021), poor performance status (OR 2.94; 95% CI, 1.10-7.87; p = 0.032), and lower preoperative body weight (BW) (OR 0.96; 95% CI, 0.94-0.99; p = 0.009) were the independent variables predicting the long-time placement of feeding enterostomy. CONCLUSION: Nutritional support via feeding enterostomy for more than 90 days after esophagectomy was required in 23.5% of patients. The elderly, poor performance status, and lower BW were the independent preoperative factors for predicting the long-term placement of feeding enterostomy.

Robot-assisted minimally invasive esophagectomy (RAMIE) for esophageal cancer has been performed increasingly frequently over the last few years. Robotic systems with articulated devices and tremor filtration allow surgeons to perform such procedures more meticulously than by hand. The feasibility of RAMIE has been demonstrated in several retrospective comparative studies, which showed similar short-term outcomes to conventional minimally invasive esophagectomy (cMIE). Considering the number of harvested lymph nodes, RAMIE may be superior to cMIE in terms of left upper mediastinal lymph node dissection. However, whether or not the addition of a robotic system to cMIE can help improve perioperative and oncological outcomes remains unclear. Given the lack of established evidence from randomized controlled trials, we must await the results of ongoing studies to reach any meaningful conclusions. Further advancements in robotic platforms, as well as the reduction in medical expenses, will be essential to demonstrate the real benefit of RAMIE.

BACKGROUND: Squamous cell carcinoma antigen (SCC-Ag) is a widely used tumor marker of SCC. However, the clinical significance of serum SCC-Ag levels in recurrent esophageal SCC (ESCC) remains unclear. This study aimed to investigate the clinical relevance of serum SCC-Ag levels in patients with recurrent ESCC after surgery. METHODS: This study retrospectively analyzed 208 patients who experienced recurrence after curative resection for ESCC. Serum SCC-Ag levels at the time of recurrence were collected from the patients' records. The patients were classified into tertiles based on the serum SCC-Ag values (low, middle, and high), and the clinical characteristics and outcomes were compared among the groups. RESULTS: Significant differences in sex (p = 0.001), pathologic T (p = 0.034), and N stages of primary cancer (p = 0.015) were observed among the groups. Although the recurrence patterns did not differ significantly, a high SCC-Ag was significantly associated with multiple recurrences (p = 0.019). The high-SCC-Ag group patients demonstrated a shorter time to recurrence than the other groups (p = 0.044). The SCC-Ag levels were significantly associated with overall survival after recurrence (p = 0.036). Multivariate analysis showed that serum SCC-Ag value at recurrence was an independent poor prognosticator (p = 0.031). CONCLUSION: Elevated serum SCC-Ag levels at recurrence were significantly associated with a reduced time to recurrence, multiple recurrences, and a poor prognosis after recurrence. An alternative to the current standard treatment is required to improve the outcome for patients with high serum SCC-Ag levels at recurrence.

BACKGROUND: Anastomotic leakage (AL) is one of the most common complications after esophagectomy. Although some patients have a history of peptic ulcers or other prior stomach diseases, the influence of a damaged stomach (DS) on AL incidence remains unclear. Therefore, we investigated the association between DS and incidence of AL in patients who underwent esophagectomy. PATIENTS AND METHODS: Between 2015 and 2019, a total of 447 consecutive patients who underwent cervical esophagogastrostomy using gastric tube following esophagectomy were enrolled. DS was defined on the basis of endoscopic findings of ulcers or scars due to medical history or prior treatment. We compared the incidence of AL between patients with DS and those with a healthy stomach (HS). Univariate and multivariate logistic regression analyses were used to identify factors that could predict AL incidence. RESULTS: Fifty-one patients (11.4%) had DS. Causes of DS included peptic ulcer (n = 36), endoscopic resection for early gastric cancer (n = 9), percutaneous endoscopic gastrostomies (n = 5), and post-chemotherapy scar for gastric malignant lymphoma (n = 1). Overall, AL occurred in 35 patients (7.8%). The incidence of AL in the DS group was significantly higher than in the HS group (15.7 vs. 6.8%, p = 0.03). DS was one of the independent predictive factors for AL (odds ratio, 2.75; 95% confidence interval, 1.10-6.92; p = 0.03) on multivariate analysis. Further, the diseases in the lower third of the conduit were associated with AL. CONCLUSIONS: Presence of DS can predict AL in patients who underwent cervical esophagogastrostomy after esophagectomy.

BACKGROUND: Esophagectomy with lymph node dissection is a choice of additional treatment after noncurative endoscopic resection (ER) of T1N0 esophageal squamous cell carcinoma (ESCC). The efficacy and safety of esophagectomy in this situation remain unclear when compared with upfront esophagectomy. METHODS: We investigated the short- and long-term outcomes of 321 patients with clinical T1N0M0 ESCC who underwent curative esophagectomy, and compared the status of lymph node metastasis, surgical results, and the prognosis between the ER and non-ER groups. RESULTS: The ER group consisted of 57 patients (17.8%), while the non-ER group consisted of 264 patients (82.2%). The incidence of lymph node metastasis was not significantly different between the ER (24.6%) and non-ER groups (30.7%), and there was no significant difference in surgical outcomes between the groups. The distribution of metastatic lymph nodes was very similar between the groups. However, 13 of 14 patients (93%) with lymph node metastasis in the ER group and 63 of 82 patients (77%) with lymph node metastasis in the non-ER group had pN1 disease, while the remaining 18 patients (23%) with lymph node metastasis in the non-ER group had pN2 or N3 disease. Overall and relapse-free survival rates were significantly better in the ER group than in the non-ER group (p < 0.05 and p < 0.01, respectively). To date, no patients in the ER group experienced disease recurrence. CONCLUSIONS: Additional esophagectomy is a safe and effective treatment modality for patients after noncurative ER.

BACKGROUND: Although squamous cell carcinoma antigen (SCC-Ag) is a tumor marker widely used to estimate the progression of esophageal SCC (ESCC), only a few studies have focused on the relationship between serum SCC-Ag levels and the therapeutic effect of neoadjuvant chemotherapy (NAC). OBJECTIVE: This study aimed to elucidate the clinical significance of pretherapeutic serum SCC-Ag levels in patients who underwent NAC followed by esophagectomy. METHODS: Data of 453 patients who underwent NAC followed by esophagectomy were collected from the esophageal cancer database of two high-volume Japanese centers. Serum SCC-Ag levels were measured prior to NAC, and the pathological therapeutic effect of NAC and patient survival were evaluated. Patients were classified according to the tertiles of the serum SCC-Ag value (low, middle, and high groups), and the outcomes among the groups were compared. RESULTS: The levels of serum SCC-Ag were significantly associated with tumor stage (p < 0.01). With regard to the pathological therapeutic effect, the levels of serum SCC-Ag were negatively correlated with the therapeutic effect (p = 0.02). Moreover, increased levels of serum SCC-Ag negatively influenced relapse-free survival (p < 0.01). Multivariate analyses revealed the 'high' group as the independent factor for both the unfavorable therapeutic effect (p = 0.01) and the increased risk of disease recurrence (p < 0.01) when compared with the 'low' group. CONCLUSION: Elevated levels of pretherapeutic serum SCC-Ag are significantly associated with advanced tumor stage, poor response to NAC, and increased risk of disease recurrence.

BACKGROUND: Endoscopic resection (ER) has been widely implemented for cT1N0 esophageal squamous cell carcinoma (ESCC). Additional therapy, including esophagectomy and chemoradiotherapy (CRT), is sometimes required after noncurative ER. METHODS: We retrospectively reviewed 108 patients who received any additional treatment following noncurative ER (positive vertical margins, lymphovascular invasion, or invasion depth of submucosa or more), and compared the short- and long-term outcomes between the two treatment modalities. RESULTS: Of 108 patients, 56 underwent esophagectomy (E group), and 52 received CRT (CRT group). A positive vertical margin was observed in 17 (14.8%) patients and high risks of occult lymph node metastasis were observed in 91 (85.2%) patients, as well as lymphovascular invasion in 35 (32.4%) patients, invasion depth of the submucosa or more in 27 (25.0%) patients, and both in 29 (26.9%) patients. The E group patients were significantly younger (p = 0.046) and tended to present with larger tumors than those in the CRT group (p = 0.057). Lymphatic invasion was more frequent in the E group (p = 0.019), and, furthermore, one treatment-related death was observed in the E group. There were no significant differences between the groups in overall and disease-specific survival (p = 0.406 and 0.151, respectively), however, recurrence was only observed in the CRT group. CONCLUSION: Both esophagectomy and CRT are safe and effective as additional treatments after noncurative ER in patients with ESCC. Esophagectomy is oncologically safe, whereas a risk of postoperative morbidity and mortality remains. Although the adverse events are acceptable, CRT has a certain degree of risk of disease recurrence.

BACKGROUND: Pharyngolaryngectomy with total esophagectomy (PLTE) is often indicated for patients with synchronous head and neck cancer and thoracic esophageal cancer or those with head and neck cancer extending to the upper mediastinum. A long conduit is required for the reconstruction, and the blood flow at the tip of the conduit is not always sufficient. Thus, reconstructive surgery after PLTE remains challenging, and optimal reconstruction methods have not been elucidated to date. METHODS: This analysis investigated 65 patients who underwent PLTE. The short-term outcomes among the procedures were compared to explore the optimal digestive reconstruction methods. RESULTS: We used a simple gastric conduit for 7 patients, a gastric conduit with microvascular anastomosis (MVA) for 10 patients, an elongated gastric conduit with an MVA for 20 patients, a gastric conduit combined with a free jejunum transfer (FJT) for 25 patients, and other procedures for 3 patients. Postoperatively, 17 (26.2%) of the patients experienced severe complications, classified as Clavien-Dindo grade 3b or higher, including graft failure for 3 patients (6.2%). Anastomotic leakage was found in six patients (9.2%), and all leakages occurred at the pharyngogastric anastomosis. The reoperation rate was 15.4% (n = 10), and three patients (4.6%) died of massive bleeding from major vessels. The patients who underwent simple gastric conduit more frequently had graft failure (P = 0.04), anastomotic leakage (P < 0.01), and reoperation (P = 0.04) than the patients treated with the other reconstructive methods. CONCLUSION: Additional procedures such as MVA, gastric tube elongation, and FJT contribute to improving the outcomes of reconstruction after PLTE.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is known to be a risk factor of pneumonia after esophagectomy. In this study, we investigated the relationship of airflow limitation with the occurrence and the severity of pneumonia in esophageal cancer patients who underwent esophagectomy. METHODS: We enrolled 844 patients who underwent curative esophagectomy between 2009 and 2018. The airflow limitation was evaluated using the percent-predicted forced expiratory volume at 1 s (%FEV1) with spirometry. RESULTS: There were 597 (70.7%), 141 (16.7%), 68 (8.1%), and 38 patients (4.5%) with %FEV1 of ≥ 90%, 80-90%, 70-80%, and < 70% categories, respectively. One hundred and ninety-one patients (22.6%) occurred pneumonia, and the incidences of pneumonia in each category of patients were 18.8%, 28.4%, 29.4%, and 50.0%, respectively. In multivariate analysis, the categories of 80%-90%, 70-80%, and < 70% were significantly associated with a higher incidence of postoperative pneumonia (OR 1.57; 95% CI 1.02-2.43, OR 1.87; 95% CI 1.04-3.36, OR 3.34; 95% CI 1.66-6.71, respectively), with the %FEV1 category of ≥ 90% as reference. The incidence of severe pneumonia of Clavien-Dindo grade III or higher was also significantly associated with the %FEV1. In patients without COPD, the incidence of pneumonia was significantly higher in those with %FEV1 < 90% than in those with %FEV1 ≥ 90% (32.2% versus 17.5%, p < 0.001). CONCLUSIONS: The airflow limitation can help predict the occurrence of pneumonia after esophagectomy in patients with and without COPD. Exclusive preventive measures should be considered in patients with reduced %FEV1 undergoing esophagectomy.

PURPOSE: This study evaluates surgical outcomes of Ivor Lewis esophagectomy (ILE) in our institution, with the transition from open ILE to hybrid or totally minimally invasive ILE (MI-ILE). METHODS: Selected patients who underwent ILE for esophageal cancer between 2013 and 2020 were included. We retrospectively investigated the patients' background characteristics and the short-term surgical outcomes. RESULTS: In this period, among a total of 858 esophagectomies, selected seventy-one patients (8.3%) underwent ILE, consisted of 17 cases with completely open procedures, 27 with hybrid MI-ILE, and 27 with total MI-ILE. The major indications for ILE were adenocarcinoma of the distal esophagus or esophagogastric junction (33.8%) and patients with prior treatment of head and neck cancer (31.0%). Among these approaches, there were no significant differences in the characteristics including age, body mass index (BMI), tumor location, preoperative therapy, and clinical TNM stage, except for histology. Compared to the completely open and hybrid groups, incidences of both total and severe complications in the total MI-ILE group were significantly lower (total 70.6 vs. 66.6 vs. 37.0%, p=0.036; severe 35.3 vs. 44.4 vs. 11.1%, p=0.023), and also, those of pneumonia (41.2 vs. 29.6 vs. 7.4%, p=0.026) and postoperative stricture (11.8 vs. 18.5 vs. 0%, p=0.001) were significantly fewer in the total MI-ILE group. CONCLUSIONS: We have been able to achieve the transition from completely open to total MI-ILE with better short-term outcomes. Total MI-ILE with linear-stapled anastomosis can be a good alternative to open procedures for the selected patients with reducing the incidence of postoperative pneumonia and anastomotic stricture.

BACKGROUND: A limited number of studies have evaluated the risk of developing venous thromboembolism (VTE) during neoadjuvant chemotherapy (NAC) for esophageal cancer and the efficacy of a D-dimer (DD)-based VTE screening (DBS). In the present study, we aimed to clarify the changes in DD levels and the effectiveness of DBS. METHODS: We included 234 patients who underwent esophagectomy between August 2017 and July 2019 and evaluated the changes in DD levels before and after NAC. We had introduced the DBS strategy in August 2018, in which we recommended ultrasound (US) of the leg or computed tomography (CT) with the deep vein thrombosis (DVT) protocol. We then evaluated the incidence of VTE detected by DBS compared with that in the clinical practice as a control. RESULTS: The DD levels were significantly increased after NAC. After the introduction of DBS, the proportion of patients who underwent US and CT after NAC was significantly increased. VTE was more frequently detected in the DBS group than in the control group (16.7% vs. 3.0%, p < 0.02) among patients who underwent NAC. Pulmonary embolism (PE) during NAC was also more frequent in the DBS than in the control group (7.6% vs. 1.5%, p = 0.06). The DD levels after NAC were significantly higher in patients with VTE than in those without. CONCLUSIONS: NAC for patients with esophageal cancer increases the risk of developing VTE. DBS is useful in identifying asymptomatic DVT and may contribute to improving patient safety.
