Cost burden following esophagectomy: A single centre observational study.

BACKGROUND: Cost analyses of patients undergoing esophagectomy is valuable for identifying modifiable expenditure drivers to target and curtail costs while improving the quality of care. We aimed to define the cost-complication relationship after esophagectomy and delineate the incremental contributions to costs. AIM: To assess the relationship between the hospital costs and potential cost drivers post esophagectomy and investigate the relationship between the cost-driving variables (predicting variables) and hospital costs (dependent variable). METHODS: In this retrospective single center study, the severity of complications was graded using the Clavien-Dindo (CD) classification system. Key esophagectomy complications were categorized and defined according to consensus guidelines. Raw costing data included the in-hospital costs of the index admission and any unplanned admission within 30 postoperative days. We used correlation analysis to assess the relationship between key clinical variables and hospital costs (in United States dollars) to identify cost drivers. A mediation model was used to investigate the relationship between these variables and hospital costs. RESULTS: A total of 110 patients underwent primary esophageal resection. The median admission cost was $47822.7 (interquartile range: 35670.2-68214.0). The total effects on costs were $13593.9 (95%CI: 10187.1-17000.8, P < 0.001) for each increase in CD severity grade, $4781 (95%CI: 3772.7-5789.3, P < 0.001) for each increase in the number of complications, and $42552.2 (95%CI: 8309-76795.4, P = 0.015) if a key esophagectomy complication developed. Key esophagectomy complications drove the costs directly by $11415.7 (95%CI: 992.5-21838.9, P = 0.032). CONCLUSION: The severity and number of complications, and the development of key esophagectomy complications significantly contributed to total hospital costs. Continuous institutional initiatives and strategies are needed to enhance patient outcomes and minimize costs.

Assessing the outcomes of posterior thoracic para-aortic lymph node dissection after induction chemotherapy in patients with esophageal squamous cell carcinoma.

Posterior thoracic para-aortic lymph node (TPAN) metastasis is a distant metastasis of esophageal cancer. Several case reports have shown that radical esophagectomy and lymphadenectomy for posterior TPAN improve the prognosis of patients with cStage IVB esophageal cancer and solitary posterior TPAN metastasis; however, the true value of this procedure is unclear. The primary objective of this study was to evaluate the short- and long-term outcomes of lymphadenectomy for posterior TPAN after induction chemotherapy in esophageal cancer. This study enrolled 15 patients who underwent radical esophagectomy for cStage IVB esophageal cancer with solitary posterior TPAN metastasis after induction chemotherapy between January 2013 and October 2022 at our hospital. The short- and long-term of radical esophagectomy and lymphadenectomy for posterior TPAN were retrospectively evaluated. All patients who underwent radical esophagectomy and lymphadenectomy for posterior TPAN achieved a pR0 in this study. The median operative time and intraoperative blood loss were 385 minutes and 164 ml, respectively. Four patients (26.7%) had postoperative complications of Clavien-Dindo grade II or more. The median postoperative hospital stay was 15 days. The 5-year overall survival and recurrence-free survival rates were 55.6% (95% confidence interval: 23.1-79.0) and 55.0% (95% confidence interval: 25.3-77.2), respectively. We showed that lymphadenectomy for posterior TPAN metastasis was associated with an improved prognosis of some patients with advanced esophageal cancer. This technique may serve as a viable treatment option for patients who respond well to induction chemotherapy.

Low psoas muscle index has a negative impact on survival after minimal invasive esophagectomy for cancer in European men.

INTRODUCTION: Sarcopenia, a key component of frailty in cancer patients, is associated with complicated procedures and worse survival after esophageal resection. The psoas muscle index (PMI) has been implicated as a possible sarcopenia imaging marker. This retrospective study aims to elucidate the effect of PMI and BMI in a cohort in Europe after totally minimally invasive esophagectomy for cancer. METHODS: The study included 318 consecutive adult patients (261 men and 57 women) who underwent minimally invasive esophagectomy for cancer between January 2016 and April 2021 in a German University Hospital. The PMI was measured at the third lumbar vertebra in the preoperative CT scan. The endpoints postoperative complication rates and survival rates were analysed and correlated with PMI and BMI according to gender. RESULTS: Male patients with low PMI (< 5.3 cm2/ m2) had a significantly higher rate of postoperative pulmonary and cardiac complications (p = 0.016, respectively p = 0.018). Low PMI and low BMI (<25 kg/m2) were associated with decreased survival rates in the univariate (p < 0.001) and multivariate analysis in male patients (p = 0.024, respectively 0.004). Having a low PMI (< 5.3 cm2/ m2) was significantly associated with worse overall survival in normal and underweight men (p < 0.001), but not in obese men with a BMI ≥ 25kg/m2 (p = 0.476). CONCLUSION: Preoperative PMI and BMI are valid risk factors regarding postoperative survival after minimal invasive esophagectomy for cancer especially in a male European cohort.

Efficacy and prognostic analysis of carbon nanotracers combined with the da Vinci robot in the treatment of esophageal cancer.

BACKGROUND: Traditional methods cannot clearly visualize esophageal cancer (EC) tumor contours and metastases, which limits the clinical application of da Vinci robot-assisted surgery. AIM: To investigate the efficacy of the da Vinci robot in combination with nanocarbon lymph node tracers in radical surgery of EC. METHODS: In total, 104 patients with early-stage EC who were admitted to Liuzhou worker's Hospital from January 2020 to June 2023 were enrolled. The patients were assigned to an observation group (n = 52), which underwent da Vinci robot-assisted minimally invasive esophagectomy (RAMIE) with the intraoperative use of nanocarbon tracers, and a control group (n = 52), which underwent traditional surgery treatment. The operation time, intraoperative blood loss, postoperative drainage tube indwelling time, hospital stay, number of lymph nodes dissected, incidence of complications, and long-term curative effects were comparatively analyzed. The postoperative stress response C-reactive protein (CRP), cortisol, epinephrine (E) and inflammatory response interleukin (IL)-6, IL-8, IL-10, and tumor necrosis factor-alpha (TNF-α) were evaluated. RESULTS: Compared with the control group, the observation group had significantly lower postoperative CRP, cortisol, and E levels (P < 0.05) with a milder inflammatory response, as indicated by lower IL-6, IL-10, and TNF-α levels (P < 0.05). Patients who underwent RAMIE had less intraoperative blood loss and shorter operation times and hospital stays than those who underwent traditional surgery. The average number of dissected lymph nodes, time of lymph node dissection, and mean smallest lymph node diameter were all significantly lower in the observation group (P < 0.05). The rate of postoperative complications was 5.77% in the observation group, significantly lower than the 15.38% observed in the control group. Furthermore, the lymphatic metastasis rate, reoperation rate, and 12- and 24-month cumulative mortality in the observation group were 1.92%, 0%, 0%, and 0%, respectively, all of which were significantly lower than those in the control group (P < 0.05). CONCLUSION: The treatment of EC using the da Vinci robot combined with nanocarbon lymph node tracers can achieve good surgical outcomes and demonstrates promising clinical applications.

Conversion chemoradiotherapy combined with nab-paclitaxel plus cisplatin in patients with locally advanced borderline-resectable or unresectable esophageal squamous cell carcinoma: a phase i/ii prospective cohort study.

BACKGROUND: To evaluate the efficacy and safety of nab-paclitaxel plus cisplatin as the regimen of conversional chemoradiotherapy (cCRT) in locally advanced borderline resectable or unresectable esophageal squamous cell carcinoma (ESCC). METHODS: Patients with locally advanced ESCC (cT3­4, Nany, M0­1, M1 was limited to lymph node metastasis in the supraclavicular area) were enrolled. All the patients received the cCRT of nab-paclitaxel plus cisplatin. After the cCRT, those resectable patients received esophagectomy; those unresectable patients continued to receive the definitive chemoradiotherapy (dCRT). The locoregional control (LRC), overall survival (OS), event-free survival (EFS), distant metastasis free survival (DMFS), pathological complete response (pCR), R0 resection rate, adverse events (AEs) and postoperative complications were calculated. RESULTS: 45 patients with ESCC treated from October 2019 to May 2021 were finally included. The median follow-up time was 30.3 months. The LRC, OS, EFS, DMFS at 1 and 2 years were 81.5%, 86.6%, 64.3%, 73.2 and 72.4%, 68.8%, 44.8%, 52.7% respectively. 21 patients (46.7%) received conversional chemoradiotherapy plus surgery (cCRT+S). The pCR rate and R0 resection rate were 47.6 and 84.0%. The LRC rate at 1 and 2 years were 95.0%, 87.1% in cCRT+S patitents and 69.3%, 58.7% in dCRT patients respectively (HR, 5.14; 95%CI, 1.10-23.94; P = 0.021). The toxicities during chemoradiotherapy were tolerated, and the most common grade 3-4 toxicitiy was radiation esophagitis (15.6%). The most common postoperative complication was pleural effusion (38.1%) and no grade ≥ IIIb complications were observed. CONCLUSION: nab-paclitaxel plus cisplatin are safe as the regimen of conversional chemoradiotherapy of ESCC.

Esophagectomy for esophageal cancer in patients with a history of total pharyngolaryngectomy: a Japanese nationwide retrospective cohort study.

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.

Preoperative camrelizumab combined with chemotherapy for borderline resectable ESCC: A single-arm, prospective, phase 2 study.

BACKGROUND: We investigated the safety and efficacy of preoperative camrelizumab combined with chemotherapy for treating thoracic borderline resectable esophageal squamous cell carcinoma (Br-ESCC) (ChiCTR2200056728). METHODS: Patients with thoracic Br-ESCC received intravenous camrelizumab plus chemotherapy and underwent esophagectomy. The primary endpoint was the pathologic complete response (pCR) rate. We introduced computed tomography and endoscopic examination into the diagnostic criteria to increase its reproducibility. Additionally, we defined a new resection status, Rbr+/-, for Br-ESCC. FINDINGS: Thirty-one patients with Br-ESCC were ultimately enrolled in this study. Overall, 71.0% (22/31) of the patients underwent esophagectomy. R0 resection was achieved in 81.8% of patients (18/22). pCR and major pathological response were observed in 40.9% (9/22) and 63.6% (14/22) of the resected patients, respectively. Eighteen R0 resection patients were redefined according to our Rbr definition; 61.1% (11/18) were classified as Rbr+ resection, and 38.9% (7/18) were classified as Rbr- resection. With a median postoperative follow-up of 17.9 months, 4 patients out of 11 who underwent Rbr+ resection experienced local recurrence (2 of whom achieved pCR). However, no patients (0/7) who underwent Rbr- resection experienced local recurrence. CONCLUSIONS: Esophagectomy after neoadjuvant immunochemotherapy is a promising radical treatment for Br-ESCC. R0 resection was achieved in 81.8% of patients, and a pCR was observed in 40.9% of resected patients. Even after complete excision, Rbr+ resection leads to a higher rate of local recurrence in patients with Br-ESCC. FUNDING: This study was supported by the Key Scientific Research Projects of the Institutions of Higher Learning in Henan Province (no. 21A320032).

Bilateral transcervical mediastinoscopic-assisted transhiatal laparoscopic esophagectomy compared with thoracolaparoscopic esophagectomy for esophageal cancer: a propensity score-matched analysis.

BACKGROUND: Transcervical mediastinoscopic esophagectomy for esophageal and esophagogastric junction cancer is indicated in select institutions because of the complex surgical technique required and the unfamiliar surgical view compared with the standard transthoracic esophagectomy approach. This study was performed to compare the feasibility and efficacy of bilateral transcervical mediastinoscopic-assisted transhiatal laparoscopic esophagectomy (BTC-MATLE) with thoracolaparoscopic esophagectomy (TLE) for esophageal cancer. METHODS: This study involved 392 consecutive patients with esophageal cancer who underwent curative minimally invasive esophagectomy with R0 resection (excluding salvage, conversion, and two-stage operations and open thoracotomy) at the National Cancer Center Hospital from 2017 to 2022. The patients underwent either BTC-MATLE or TE (32 and 360 consecutive patients, respectively). Propensity score-matching analysis was used to balance the baseline differences by covariates of age, performance status, and clinical stage. RESULTS: There were statistically significant differences in age, performance status, cT factor, cN factor, cStage, preoperative treatment, and surgical history for respiratory disease. After propensity score-matching, these significant differences (excluding a surgical history of respiratory disease) were no longer statistically significant, and 27 patients were assigned to each group. The total operation time and the postoperative intensive care unit stay were significantly shorter in the BTC-MATLE than TLE group. There were no significant differences in overall postoperative complications or the three major postoperative complications of recurrent laryngeal nerve paralysis, anastomotic leakage, and pneumonia, even for patients whose preoperative pulmonary function indices (vital capacity and forced expiratory volume in 1 s) were significantly lower in the BTC-MATLE than TLE group. The numbers of total and thoracic harvested lymph nodes were significantly higher in the TLE than BTC-MATLE group; however, there was no significant difference in the recurrence rate between the two groups. CONCLUSION: BTC-MATLE may provide the same feasibility and oncological outcomes as TLE even for patients with significantly lower pulmonary function.

Esophagectomy after definitive chemoradiation in esophageal cancer: a safe therapeutic strategy.

The standard treatment regimen for esophageal cancer is chemoradiation followed by esophagectomy. However, the use of neoadjuvant chemoradiotherapy damages the surrounding tissue, which potentially increases the risk of postoperative complications, including anastomotic leakage. The impact of definitive chemoradiotherapy (dCRT, 50.4 Gy radiotherapy) compared to the standard neoadjuvant scheme (nCRT, 41.4 Gy radiotherapy) prior to surgery on the incidence of anastomotic leakage remains poorly understood. To study this, all patients who received dCRT between 2011 and 2021 followed by esophagectomy were included. For each patient, two patients who received nCRT were selected as matched controls. Outcomes included postoperative anastomotic leakage, pulmonary and other complications, anastomotic stenosis, pulmonary and other postoperative complications (Clavien Dindo Classification ≥1), and overall survival. One hundred and eight patients were included with a median follow-up of 28 months. The time between neoadjuvant treatment and surgery was longer in the dCRT group compared to the nCRT group (65 vs. 48 days, P < 0.001). Postoperatively, significantly more patients in the dCRT group suffered from anastomotic leakage (11% vs. 1%, P = 0.04) and anastomotic stenosis (42% vs. 17%, P < 0.01). No differences were found for other complications or overall survival between both groups. In conclusion, preoperative dCRT is associated with a higher risk of anastomotic leakage and stenosis. These complications, however, can be treated effectively. Therefore, esophagectomy after dCRT is considered to be an appropriate treatment strategy in a selected patient group.

Gastric preconditioning via percutaneous angioembolization before esophagectomy in patients at high risk for esophageal leak.

Anastomotic leaks and stenoses remain critical complications in esophagectomy and are related to conduit perfusion. Surgical gastric preconditioning has been described but requires additional surgery and creates scar tissue, potentially hindering future operation. We sought to evaluate the feasibility and safety of percutaneous gastric preconditioning by angioembolization to improve perfusion of gastric conduits before esophagectomy in a high-risk patient cohort. Patients pending an esophagectomy for cancer and deemed to be high risk for anastomotic complications underwent preconditioning by image-guided angioembolization. Preconditioning was performed on an outpatient basis by means of superselective embolization of the left gastric and short gastric arteries. Intraoperative conduit perfusion evaluation with indocyanine green and postoperative surgical outcomes was reviewed. Seventeen patients underwent gastric preconditioning, with no complications observed. Thirteen of the 17 patients ultimately underwent esophagectomy; the remaining four patients were not candidates for an operation. Patients proceeded to surgery a median of 23 days (interquartile range, 21-27 days) after preconditioning. The intraoperative indocyanine green perfusion of all conduits was appropriate, with no tip demarcation and with a median time to dye uptake of 20s (interquartile range, 15-20s). There were no anastomotic stenoses or leaks noted within the series. Gastric conduit preconditioning by percutaneous angioembolization of the left gastric and short gastric arteries can be performed safely and without operative delay in high-risk patients. Further evaluation of preconditioning for conduit optimization is warranted to limit the critical complications of anastomotic leak and stenosis in esophagectomy.

Jejunostomy feeding plus oral feeding versus intravenous nutrition plus oral feeding after esophageal cancer resection: a comparative retrospective cohort study.

Background: There are multiple choices for the nutritional management mode after esophageal cancer surgery. Currently, there is still controversy regarding which nutritional management mode has an impact on the postoperative recovery and overall survival (OS) of patients. This study aims to compare the differences between two commonly used clinical nutritional management modes: jejunostomy feeding plus oral intake (JF plus OI) and intravenous nutrition plus oral intake (IN plus OI), in terms of short-term efficacy and 3-year OS, in order to further explore the optimal mode of enteral nutrition management after esophageal cancer surgery. Methods: We evaluated esophageal cancer patients who underwent radical surgery at Union Hospital of Fujian Medical University between January 1, 2010 and January 1, 2020. The purpose of this analysis was to compare the perioperative complications, Nutritional Risk Screening 2002 (NRS2002) nutritional scores at 1 week, 2 weeks, 1 month, and 3 months after surgery, as well as the 3-year OS rates, between two different nutritional management approaches: JF plus OI and IN plus OI following esophageal cancer surgery. Results: Among the 822 patients included, 668 and 154 patients belonged to JF plus OI and IN plus OI groups, respectively. After propensity score matching, 149 patients per group were evaluated. The amount of gastric drainage fluid was higher in the IN plus OI group (P<0.05), and the incidence of postoperative gastrointestinal emptying disorder and intestinal obstruction was significantly higher in the JF plus OI group (P<0.05). The IN plus OI group had a higher incidence of perioperative hypoproteinemia (P<0.05), and a higher risk of malnutrition in 2 weeks after surgery (P<0.05). The 3-year OS was not significantly different (P>0.05). Conclusions: JF plus OI may be the preferable nutritional management approach after esophageal cancer resection as it can potentially reduce perioperative nutritional deficiency. However, attention should be paid to the risk of gastrointestinal emptying and intestinal obstruction associated with JF.

Preoperative administration of camrelizumab combined with chemotherapy for borderline resectable esophageal squamous cell carcinoma (BRES-1): study protocol of a single-arm, open-label, phase II study.

Background: The prognosis and first-line treatment response of patients with borderline resectable esophageal squamous cell carcinoma (ESCC) are unsatisfactory. We are conducting the borderline resectable esophageal squamous (BRES-1) study to evaluate the safety and efficacy of camrelizumab combined with chemotherapy in patients with borderline resectable ESCC. Methods: A total of 30 patients with borderline resectable ESCC will be enrolled in the BRES-1 study. These patients will undergo three stages of treatment: neoadjuvant therapy, surgery, and adjuvant therapy. Preoperative therapies will include camrelizumab, cisplatin, and nab-paclitaxel. Preoperative therapies will include camrelizumab, which will be given every 3 weeks for 6 weeks at a dose of 200 mg (baseline weight <50 kg, 3 mg/kg), nab-paclitaxel (130 mg/m2 on days 1 and 8 of one period with 21 days, a total of two cycles), and cisplatin (75 mg/m2 on day 1 of one period with 21 days, a total of two cycles). Patients will undergo esophagectomy 3-6 weeks after completing the neoadjuvant treatment. Three weeks after surgery, camrelizumab combined with chemotherapy will continue to be used for two cycles of maintenance therapy. Then, only camrelizumab will be administered for an entire year. The primary endpoint of this study will be pathological complete response (pCR). Discussion: The BRES-1 trial will evaluate the efficacy and safety of camrelizumab combined with chemotherapy for patients with borderline resectable ESCC. Translational research will explore perioperative complications and drug-related adverse events (AEs). Trial Registration: ChiCTR, ChiCTR2200056728.

Short-term outcomes of three- and two-field lymphadenectomy with minimally invasive esophagectomy for esophageal cancer: a propensity score-matching analysis.

Background: Whether patients can benefit from three-field lymphadenectomy (3-FL) in minimally invasive esophagectomy (MIE) remains unclear. This study retrospectively compared short-term outcomes between 3-FL and two-field lymphadenectomy (2-FL) in MIE for patients with esophageal cancer (EC) and aimed to evaluate the clinical significance of 3-FL. Methods: There were 284 patients enrolled in the study (124 patients with 3-FL and 160 patients with 2-FL). The cases were matched based on their propensity scores using a matching ratio of 1:1, the nearest neighbor matching protocol, and a caliper of 0.02. Patients were propensity-score matched for sex, cancer location, Age-adjusted Charlson Comorbidity Index (ACCI), and neoadjuvant treatment. The short-term outcomes were postoperative complications, operation characteristics, pathology results and postoperative hospital stay. Results: There were no significant differences in intraoperative hemorrhage, postoperative hospital stay, or postoperative complications between the 2-FL and 3-FL groups. The operation time of the two groups was significantly different (227.1±46.2 vs. 248.5±45.9 min, P=0.001); the operation time of the 3-FL group was about 20 minutes longer than that of the 2-FL group. The number of lymphatic nodes (LNs) obtained in the 3-FL group was significantly higher than that in the 2-FL group (31.3±12.9 vs. 54.6±18.0, P<0.001). Pathological N stage was also significantly different (P=0.002); the 3-FL group was more advanced than the 2-FL group. Conclusions: Compared to 2-FL MIE, 3-FL MIE does not increase postoperative complications, can obtain more LNs, and improves the accuracy of tumor LN staging.

The anastomotic leak triad: preoperative patient characteristics, intraoperative risk factors, and postoperative outcomes.

BACKGROUND: The aim of this study was to determine perioperative risk factors associated with anastomotic leak (AL) after minimally invasive esophagectomy (MIE) and its association with cancer recurrence and overall survival. METHODS: This retrospective observational study of electronic health record data included patients who underwent MIE for esophageal cancer between September 2013 and July 2023 at a tertiary center. The primary outcome was AL after esophagectomy, whereas the secondary outcomes included time to cancer recurrence and overall survival. Perioperative patient factors were evaluated to determine their associations with the primary and the secondary outcomes. Propensity score-matched logistic regression assessed the associations between perioperative factors and AL. Kaplan-Meier survival curves compared cancer recurrence and overall survival by AL. RESULTS: A total of 251 consecutive patients with esophageal cancer were included in the analysis; 15 (6%) developed AL. Anemia, hospital complications, hospital length of stay, and 30-day readmissions significantly differed from those with and without AL (P = .037, <.001, <.001, and.016, respectively). Moreover, 30- and 90-day mortality were not statistically affected by the presence of AL (P = .417 and 0.456, respectively). Logistic regression modeling showed drug history and anemia were significantly associated with AL (P = .022 and.011, respectively). The presence of AL did not significantly impact cancer recurrence or overall survival (P = .439 and.301, respectively). CONCLUSION: The etiology of AL is multifactorial. Moreover, AL is significantly associated with drug history, preoperative anemia, hospital length of stay, and 30-day readmissions, but it was not significantly associated with 30- or 90-day mortality, cancer recurrence, or overall survival. Patients should be optimized before undergoing MIE with special consideration for correcting anemia. Ongoing research is needed to identify more modifiable risk factors to minimize AL development and its associated morbidity.

Safe Transition from Open to Total Minimally Invasive Esophagectomy for Cancer Utilizing Process Management Methodology.

Background: The global shift from open esophagectomy (OE) to minimally invasive esophagectomy (MIE) for treating esophageal cancer is well-established. Recent data indicate that transitioning from hybrid minimally invasive esophagectomy (hMIE) to total minimally invasive esophagectomy (tMIE) can be challenging due to concerns about higher leakage rates and lower lymph node counts, especially at the beginning of the learning curve. This study aimed to demonstrate that a safe transition from OE to tMIE for cancer is possible using process management methodology. Methods: A step-change approach was adopted in process management planning, with hMIE serving as an intermediate step between OE and tMIE. This single-center, case-control study included 150 patients who underwent the Ivor Lewis procedure with curative intent for esophageal cancer. Among these patients, 50 underwent OE, 50 hMIE (laparoscopic procedure followed by conventional right thoracotomy), and 50 tMIE (laparoscopic and thoracoscopic approach). A preceptored training scheme was implemented during execution, and treatment results were monitored and controlled to ensure a safe transition. Results: During the transition, the tMIE group was not worse than the hMIE and OE groups regarding operation duration (p = 0.135), overall postoperative complications (p = 0.020), anastomotic leakage rates (p = 0.773), 30-day mortality (p = 1.0), and oncological outcomes (based on R status (p = 0.628) and 2-year survival (p = 0.967)). Additionally, the tMIE group showed superior results in terms of major postoperative pulmonary complications (p = 0.004) and ICU stay duration (p < 0.001). Conclusions: Utilizing managerial methodology and practice in surgery, as a bridge between interdisciplinary and transdisciplinary approaches, demonstrated that transitioning from OE to tMIE, with hMIE as an intermediate step, is safe and feasible without compromising outcomes.

Esophagectomy in patients with esophageal squamous cell carcinoma and distant nodal metastasis.

The role of surgery in oligometastatic esophageal squamous cell carcinoma (ESCC) remains controversial. This study evaluated the oncological outcomes after esophagectomy in patients with ESCC with distant lymph node (LN) metastasis. Patients with ESCC and nodal metastasis treated with chemoradiotherapy or chemotherapy followed by esophagectomy between 2010 and 2020 were included. Overall survival (OS) and recurrence-free survival (RFS) were compared between patients with distant LN metastasis (dLN+) and exclusively regional LN metastasis (dLN-). The cohort comprised 69 dLN+ and 111 dLN- patients. Survival was significantly better in the dLN- group than in the dLN+ group (5-year OS, 51.9% vs. 25.5%, P < 0.001; RFS, 47.2% vs. 18.1%, P < 0.001). Stratified by the yp stage, 49 (44.1%) dLN- and 30 (43.5%) dLN+ patients achieved a pathological complete response (pCR). In the dLN- and dLN+ groups, the OS rates were significantly higher in the pCR group than in the non-pCR group (dLN-: 76.7% vs. 32.4%, P < 0.001; dLN+: 39.6% vs. 14.2%; P = 0.002). The dLN-/pCR group had the best OS, significantly outperforming the dLN-/non-pCR and dLN+/pCR groups. OS did not differ between the dLN-/non-pCR and dLN+/pCR groups. The dLN+/non-pCR group had the worst OS. The RFS analysis paralleled the OS findings. Patients with dLN+ disease had worse outcomes than their dLN- counterparts, irrespective of the pCR status. The survival rates were poor but comparable between the dLN+/pCR and dLN-/non-pCR groups. Adjuvant therapy may be required for dLN+ patients following systemic treatment and surgery, even after achieving pCR.

Clinical impact of postoperative changes in body composition on long-term outcomes in patients with esophageal cancer.

BACKGROUND & AIMS: This study aimed to investigate the temporal changes in body composition following esophagectomy in patients with esophageal cancer using bioelectrical impedance analysis and to assess the prognostic implications of these changes. METHODS: Our study included 528 patients who underwent esophagectomy and preoperative body composition measurements between January 2013 and June 2020. Postoperative body composition was measured in 493 patients at discharge as follows: 184 at 1 month, 144 at 2 months, 143 at 3 months, 103 at 6 months, 58 at 9 months, and 78 at 12 months. RESULTS: Body weight (BW) continuously decreased until the 6 postoperative months (POMs), reaching -11.5% compared with preoperative levels. Subsequently, almost no change was observed at 12 POMs. Skeletal muscle mass (SMM) decreased until 3 POMs but gradually recovered after 3 POMs. Conversely, body fat mass (BFM) consistently decreased over time post-esophagectomy. The patients were categorized into moderate (>-10%) and severe (≤-10%) groups based on % BW, % SMM, and % BFM losses at 3 POMs. Severe SMM loss at 3 POMs correlated with reduced overall survival (OS) (3-year OS: 85.9% in moderate vs. 75.1% in severe, p = 0.035). BFM loss was associated with reduced recurrence-free survival (3-year RFS: 83.3% in moderate vs. 62.0% in severe, p = 0.011). Multivariate analysis identified pStages Ⅲ and Ⅳ, % SMM loss ≤ -10%, and % BFM loss ≤ -10% as independent factors for worse OS. CONCLUSION: Post-esophagectomy, distinct temporal changes in BW, SMM, and BFM are observed. Significant reductions in SMM and BFM 3 POMs indicate a poor long-term prognosis.

Nomogram for predicting pathologic complete response following preoperative chemoradiotherapy in patients with esophageal squamous cell carcinoma.

Background: In patients with esophageal squamous cell carcinoma (ESCC), accurately predicting a pathologic complete response (pCR) to preoperative chemoradiotherapy (PCRT) has the potential to enable an active surveillance strategy without esophagectomy. We aimed to establish a reliable multiparameter nomogram model that combines tumor characteristics, imaging modalities, and hematologic markers to predict pCR in patients with ESCC who underwent PCRT and esophagectomy. Methods: We retrospectively reviewed the medical records of 457 patients with ESCC who received PCRT followed by esophagectomy between January 2005 and October 2020. The nomogram model was developed using logistic regression analysis with a training cohort and externally validated with a validation cohort. Results: In the training and validation cohorts, 44.2% (126/285) and 48.3% (83/172) of patients, respectively, achieved pCR after PCRT. The 5-year rates of overall survival, progression-free survival, and freedom from local progression in the training cohort were 51.6%, 48.5%, and 77.6%, respectively. The parameters included in the nomogram were histologic grade, clinical N stage, maximum standardized uptake value on positron emission tomography, and post-PCRT biopsy. Hematologic markers were significantly associated with survival outcomes but not with pCR. The area under the receiver operating characteristic curve of the nomogram was 0.717, 0.704, and 0.707 for the training cohort, internal validation cohort, and external validation cohort, respectively. Conclusion: Our nomogram model based on four parameters obtained from standard clinical practice demonstrated good performance in both the training and validation cohorts and could be useful to aid clinical decision-making to determine whether surgery or active surveillance strategy should be pursued.

Efficacy and outcomes of per oral plication of the (neo)esophagus (POPE) for impaired emptying in achalasia and post-esophagectomy patients.

BACKGROUND: Per-oral plication of the (neo)esophagus (POPE) is an endoscopic procedure used to improve emptying of the defunctionalized esophagus or gastric conduit, with the hope of improving symptoms and quality of life. As this procedure has only been performed in the United States for the past 4 years, safety and efficacy have not been well established. METHODS: This is a retrospective case series for patients who underwent POPE from a single institution between 2019 and 2023. Data collected included demographics, preoperative diagnoses and treatments, imaging, endoscopic data, operative intervention, 90-day complications, and response to treatment. Quality of life and patient satisfaction data were collected by phone survey. RESULTS: Seventeen cases were identified, encompassing 13 primary procedures and 4 repeat POPEs (re-POPE). Eight patients had end-stage achalasia and 5 had impaired gastric emptying after esophagectomy with gastric conduits. Median age was 65 years and median ASA was 3, with 38.5% female patients. POPE was performed with 2-6 plication sutures in an average of 75 min. The majority of patients discharged home the same day. For the 17 procedures, there were 4 complications. Two patients required antibiotics for pneumonia, while 4 required procedural intervention. There were no deaths. Preoperative symptoms improved or resolved at initial follow up in 82.3% of patients. Four patients experienced symptom recurrence and required re-POPE, 1 with achalasia and 3 with gastric conduits. Although all achalasia patients had an "end-stage esophagus," none have required esophagectomy since the introduction of POPE. CONCLUSIONS: POPE is an endoscopic procedure that is efficacious in relieving emptying difficulties for the end-stage esophagus and gastric conduit. It may obviate the need for esophagectomy or conduit replacement. Also, it can be repeated in select patients. While the risk profile of complications is favorable compared to alternative operations, patients with gastric conduits are at higher risk.
