Clinical Significance of Albumin-Bilirubin Grade in Thoracic Esophageal Squamous Cell Carcinoma.

INTRODUCTION: The albumin-bilirubin (ALBI) score evaluates liver dysfunction severity. However, this score had prognostic effects in patients with hepatocellular, pancreatic, and gastric carcinomas. We aimed to assess the predictive value of the ALBI score in patients with esophageal squamous cell carcinoma (ESCC). METHODS: Data from 154 patients with ESCC who consecutively underwent neoadjuvant chemotherapy (NAC) and subtotal esophagectomy were retrospectively investigated. The ALBI score was calculated as pre-NAC ALBI and categorized into grades 1, 2a, 2b, and 3; low-ALBI group (n = 134) was assigned with ALBI grade 1 and the other grades were assigned to the high-ALBI group (n = 20). RESULTS: The pre-NAC ALBI was significantly associated with relapse-free survival (RFS) and overall survival (P = 0.003 and P = 0.014, respectively). Based on multivariate analysis, pre-NAC ALBI, pathological T factor, and N factor were identified as independent prognostic factors for poor RFS. Multivariate and univariate analyses limited to factors were obtained before treatment, indicating high pre-NAC ALBI as an independent prognostic factor of poor overall survival (P = 0.039) and RFS (P = 0.008). With respect to pathological response to NAC, patients in the high pre-NAC ALBI group had a significantly lower response than patients in the low pre-NAC ALBI group (P = 0.010). CONCLUSIONS: Our results suggested that the pre-NAC ALBI marker predicts the long-term outcome and pathological response to NAC in patients with ESCC consecutively undergoing NAC and a subtotal esophagectomy.

Clinical impact of diarrhea during enteral feeding after esophagectomy.

BACKGROUND: Enteral feeding (EF) is recommended to enhance nutritional status after esophagectomy; however, diarrhea is a common complication of EF. We investigated the clinical and prognostic impact of diarrhea during EF after esophagectomy. METHODS: One hundred and fifty-two patients who underwent transthoracic esophagectomy were enrolled. The King's stool chart was used for stool characterization. The short- and long-term outcomes were compared between a non-diarrhea (Group N) and diarrhea group (Group D). RESULTS: A higher dysphagia score (≥ 1) was observed more frequently in Group D than in Group N (45.7% vs. 19.8%, p = 0.002). Deterioration of serum total protein, serum albumin, serum cholinesterase, and the prognostic nutritional index after esophagectomy was greater in Group D than in Group N (p = 0.003, 0.004, 0.014, and 0.001, respectively). Patients in Group D had significantly worse overall survival (OS) and recurrence-free survival (RFS) than those in Group N (median survival time (MST): OS, 21.9 vs. 30.6 months, p = 0.001; RFS, 12.4 vs. 27.7 months, p < 0.001). In stratified analysis due to age, although there was no difference in OS with or without diarrhea in young patients (MST: 24.1 months in a diarrhea group vs. 33.6 months in a non-diarrhea group, p = 0.218), patients in a diarrhea group had significantly worse OS than those in a non-diarrhea group in elderly patients (MST: 17.8 months vs. 27.9 months, p < 0.001). CONCLUSIONS: Diarrhea during EF can put elderly patients at risk of postoperative malnutrition and a poor prognosis after esophagectomy.

A silicone disc for liver retraction in laparoscopic gastrectomy reduces the postoperative increase in the liver enzyme level.

PURPOSE: To compare changes in liver enzyme levels on postoperative day 1 between patients with and without silicone disc (SD) use during liver retraction in laparoscopic gastrectomy for gastric cancer and laparoscopic gastric mobilization for esophageal cancer. METHODS: This prospective randomized controlled phase II trial was conducted between June 30, 2020, and November 30, 2022, to investigate the benefits of using an SD with a Nathanson liver retractor (NLR) compared with those using an NLR in laparoscopic gastrectomy and gastric mobilization. The primary endpoint was the change in transaminase level on postoperative day 1. RESULTS: A total of 86 patients received randomized assignments and were included in the analysis, with 44 assigned to the SD (-) group and 42 to the SD (+) group. On postoperative day 1, the SD (+) group showed a significantly lower increase in the aspartate aminotransferase levels than the SD (-) group (SD [+], 94.4% vs. SD [-], 179.8%; p = 0.012). Similarly, the SD (+) group showed a significantly lower increase in alanine aminotransferase levels than the SD (-) group (SD [+], 71.6% vs. SD [-], 201.5%; p = 0.014). CONCLUSION: In laparoscopic gastrectomy, the use of an SD combined with an NLR appears to mitigate postoperative liver dysfunction.

Ramelteon and suvorexant for postoperative delirium in elderly patients with esophageal cancer.

BACKGROUND: There is no clear evidence on the prevention of postoperative delirium with pharmacotherapy in elderly patients with esophageal cancer. This retrospective study aimed to evaluate the efficacy of ramelteon and suvorexant in preventing postoperative delirium in this patient group. METHODS: Data on 251 patients who received radical esophagectomy for thoracic esophageal cancer were collected from January 2010 to September 2021. In total, 74 patients did not receive preventive intervention, and 177 received ramelteon and suvorexant. After propensity score matching, the rate of postoperative delirium was compared between the two groups. RESULTS: Seventy-two well-balanced patients in each group demonstrated similar clinical and pathological characteristics. The mean ages of the intervention and control groups were 70.8 and 70.3 years, respectively. All the patients underwent McKeown esophagectomy, and in the volume of intraoperative blood loss or operative time did not significantly differ between the two groups. The incidence rates of postoperative hyperactive delirium were 7% (5/72) in the intervention group and 32% (23/72) in the control group (p < 0.001). No severe adverse event potentially attributable to the intervention drug was observed. The multivariate analysis showed that the use of ramelteon and suvorexant was the only independent protective factor against postoperative delirium (hazard ratio 0.157, 95% CI 0.055-0.448, p < 0.001). CONCLUSIONS: Ramelteon and suvorexant may play an important role in reducing postoperative delirium in elderly patients with esophageal cancer.

Prognostic impact of perioperative change in serum p53 antibody titers in esophageal squamous cell carcinoma.

BACKGROUND: The clinical effectiveness of tumor markers for estimating prognosis in esophageal squamous cell carcinoma (ESCC) remains unclear. We assessed the clinical impact of changes in perioperative serum p53 antibodies (s-p53-Abs) titers in ESCC. METHODS: From January 2011 to March 2021, 249 patients were enrolled in this study. Titers of s-p53-Abs were measured before the initial treatment and 3 months after esophagectomy. Patients were divided into a s-p53-Abs decreased or unchanged group (Group D, n = 217) and an increased group (Group I, n = 32). Short- and long-term outcomes were compared between the groups. RESULTS: There was no correlation between the changes in squamous cell carcinoma antigen and carcinoembryonic antigen titers and recurrence site, number of recurrent lesions, and prognosis. However, the recurrence rate was significantly higher in Group I than in Group D (53.1% vs. 28.6%, p = 0.008), especially for distant organ recurrence (37.5% vs. 18.4%, p = 0.019). Furthermore, the rate of polyrecurrence was higher in Group I than in Group D (34.4% vs. 14.3%, p = 0.009). Recurrence-free survival (RFS) was significantly worse in Group I than in Group D (median survival time, 21.2 months vs. 36.7 months, p = 0.015). Multivariate analysis revealed that lymphatic vessel infiltration (hazard ratio [HR], 1.721; 95% CI 1.069-2.772; p = 0.026), blood vessel infiltration (HR, 2.348; 95% CI 1.385-3.982; p = 0.002), advanced pathological stage (≥ III) (HR, 3.937; 95% CI 2.295-6.754; p < 0.001), and increased s-p53-Abs titers (HR, 2.635; 95% CI 1.488-4.667; p = 0.001) were independent predictors of poor RFS. CONCLUSIONS: Elevation of s-p53-Abs titers after esophagectomy can predict polyrecurrence in distant organs and poor prognosis.

Selective Lymphadenectomy for Salvage Esophagectomy in Patients with Esophageal Squamous Cell Carcinoma.

BACKGROUND: Extensive lymph node dissection increases the risk of postoperative complications, especially in salvage surgery, after definitive chemoradiotherapy (≥ 50 Gy) in patients with esophageal squamous cell carcinoma. The purpose of this retrospective study is to compare the outcomes of salvage esophagectomy with selective lymphadenectomy of only clinically positive lymph nodes. METHODS: Clinically positive lymph nodes, diagnosed as metastases using computed and positron emission tomography performed before chemoradiotherapy or salvage surgery, were targeted for dissection in selective lymphadenectomy. We compared postoperative complications between 52 patients who underwent salvage esophagectomy with selective lymphadenectomy and 207 controls who underwent nonsalvage esophagectomy with 3-field lymphadenectomy. We also analyzed postoperative recurrence pattern and survival in salvage group. RESULTS: The mean number of dissected lymph nodes was 12.9 in the salvage esophagectomy group compared with 48.1 in the 3-field lymphadenectomy group (p < 0.001). Differences in the number of postoperative complications, comparing Clavien-Dindo all-grade and ≥ grade 3, were not significant between the groups. Both 30- and 90-day mortality were 0% (0/52) in the salvage group. Five cases had recurrence only in the locoregional area without distant metastasis. Of these five cases, only one had recurrence in the subcarinal lymph node without prophylactic mediastinal lymphadenectomy. A 3-year recurrence-free survival and 3-year overall survival from salvage esophagectomy were 43.3% and 46.3%, respectively. CONCLUSIONS: It may contribute to obtaining good short- and long-term outcomes by dissecting only clinically positive lymph nodes in salvage esophagectomy.

Development and Validation of the Optimal Circumferential Resection Margin in Pathological T3 Esophageal Cancer: A Multicenter, Retrospective Study.

BACKGROUND: The clinical significance of circumferential resection margin (CRM) in esophageal squamous cell carcinoma (ESCC) remains unclear. Optimal CRM for predicting the recurrence of pathological T3 ESCC was investigated. METHODS: Seventy-three patients were retrospectively investigated in the development cohort. Patients were divided into CRM-negative and CRM-positive groups, and clinicopathological factors and survival outcomes were compared between the groups. The cutoff value was validated in another validation cohort (n = 99). RESULTS: Receiver operating characteristic analysis in the development cohort showed the cutoff value of CRM was 600 µm. In the validation cohort, patients in the CRM-positive group showed a significantly higher rate of locoregional recurrence (p = 0.006) and worse recurrence-free survival (RFS) (p < 0.001) than those in the CRM-negative group. Multivariate analysis identified positive CRM as an independent predictive factor for poor RFS (hazard ratio, 2.695; 95% confidence interval, 1.492-4.867; p = 0.001). The predictive value of our criteria of positive CRM for RFS was higher than that of the Royal College of Pathologists (RCP) and the College of American Pathologists (CAP) criteria. Stratified analysis in the neoadjuvant chemotherapy groups also revealed that the rate of locoregional recurrence was higher in the CRM-positive group than in the CRM-negative group both in the pathological N0 and N1-3 subgroups. CONCLUSIONS: CRM of 600 µm can be the optimal cutoff value rather than the RCP and CAP criteria for predicting locoregional recurrence after esophagectomy. These results may support the impact of perioperative locoregional control of locally advanced ESCC.

Survival impact of perioperative changes in prognostic nutritional index levels after esophagectomy.

BACKGROUND: The correlation between perioperative changes in nutritional status during esophagectomy and prognosis remains unclear. This study aimed to evaluate the impact of changes in prognostic nutritional index levels during the perioperative period on esophageal cancer patient survivals. METHODS: From January 2009 to May 2019, 158 patients with esophageal squamous cell carcinoma were enrolled. From the time-dependent ROC analysis, the cutoff values of preoperative and postoperative prognostic nutritional index levels were 46.9 and 40.9. Patients were divided into preoperative-high group (Group H) and preoperative-low group (Group L). Then, patients in Group L were divided into preoperative-low and postoperative-high group (Group L-H) and preoperative-low and postoperative-low group (Group L-L). Long-term outcomes and prognostic factors were evaluated. RESULTS: Patients in Group L had significantly worse overall survival than those in Group H (p = 0.001). Patients in Group L-L had significantly worse overall survival than those in Group L-H (p = 0.023). However, there was no significant difference in overall survival between Groups H and L-H (p = 0.224). In multivariable analysis, advanced pathological stage (hazard ratio 10.947, 95% confidence interval 2.590-46.268, p = 0.001) and Group L-L (hazard ratio 2.171, 95% confidence interval 1.249-3.775, p = 0.006) were independent predictors of poor overall survival. CONCLUSIONS: Patients in Group L-H had a good prognosis, similar to those in Group H. This result indicated that increasing the postoperative prognostic nutritional index level sufficiently using various intensive perioperative support methods could improve prognosis after esophagectomy in patients with poor preoperative nutritional status.

The Negative Impact of Preoperative Chemotherapy on Survival After Esophagectomy for Vulnerable Elderly Patients with Esophageal Cancer.

BACKGROUND: The standard treatment for patients 75 years of age or younger with cStage 2 or 3 esophageal cancer is preoperative chemotherapy followed by esophagectomy. The optimal treatment for elderly patients, especially those considered vulnerable, remains unclear. METHODS: This study retrospectively reviewed the data for 42 patients ages 75-80 years with cStage 2 or 3 esophageal cancer who underwent esophagectomy between October 2002 and February 2019. The patients who received preoperative chemotherapy were compared with those who did not. The study also examined short- and long-term outcomes and the impact of preoperative chemotherapy on overall survival (OS) stratified by performance status (PS). RESULTS: Of the 42 patients, 18 underwent esophagectomy without preoperative chemotherapy and 24 underwent esophagectomy after preoperative chemotherapy. A significantly greater proportion of the patients with PS 0 received preoperative chemotherapy than the patients with PS 1 (P =0.007). The multivariate analysis showed preoperative chemotherapy to be an independent negative prognostic factor for OS (hazard ratio [HR], 5.025; 95% confidence interval [CI] 1.136-22.222; P = 0.033). Subgroup analysis showed that preoperative chemotherapy had a significant negative impact on the OS of the patients with PS 1 (P < 0.001). CONCLUSION: Preoperative chemotherapy was ineffective for the patients with PS 0 and had a significantly negative impact on the OS of the patients with PS 1. Preoperative chemotherapy should not be administered to patients 75 years of age or older with cStage 2 or 3 esophageal cancer.

Evaluation of Definitive Chemoradiotherapy Versus Radical Esophagectomy in Clinical T1bN0M0 Esophageal Squamous Cell Carcinoma.

BACKGROUND: The standard treatment for patients with clinical T1bN0M0 esophageal squamous cell carcinoma is radical esophagectomy. Definitive chemoradiotherapy is regarded as a treatment option, and recently, good clinical outcomes of this treatment have been reported. This study compared prognosis after definitive chemoradiotherapy with radical esophagectomy. METHODS: From January 2011 to December 2019, 68 consecutive patients who were diagnosed clinical T1bN0M0 squamous cell carcinoma were enrolled and investigated retrospectively. Patients were classified into two groups whether treated by surgery or definitive chemoradiotherapy. Survival outcomes were compared, and subsequent therapies after recurrence were also investigated. RESULTS: Among 68 patients, 39 patients underwent surgery and 29 patients received definitive chemoradiotherapy. No significant difference was noted in overall survival between the two groups. However, the rate of 5-year recurrence-free survival was significantly lower in definitive chemoradiotherapy group than that of surgery group (91.1 vs. 62.7%, hazard ratio 3.976, 95% confidence interval 1.076-14.696, p = 0.039). Patients who had local recurrence after definitive chemoradiotherapy received endoscopic submucosal dissection or photodynamic therapy as salvage therapies, which resulted in no disease progression and a good prognosis. CONCLUSIONS: Definitive chemoradiotherapy may become a promising alternative therapy comparable with radical esophagectomy in patients with clinical T1bN0M0 esophageal squamous cell carcinoma. Early detection of recurrence by frequent follow-up after definitive chemoradiotherapy is important to control disease within local recurrence, and salvage therapy for local lesions could contribute to long-term survival.

Early detection of anastomotic leakage after esophagectomy using drain amylase levels.

BACKGROUND: Early diagnosis of anastomotic leakage (AL) after esophagectomy is essential to minimize postoperative complications. In this study, we hypothesized that drain amylase levels may be useful for early AL detection, and measuring drain amylase levels could reduce severe postoperative AL incidence. We, therefore, analyzed the usefulness of measuring drain fluid amylase levels after esophagectomy, in esophageal cancer patients. METHODS: From January 2016 to March 2020, 134 patients with esophageal cancer who underwent surgical resection with esophagogastric anastomosis in the cervical region were included. The patients were divided into a group whose cervical drain fluid amylase levels were not measured (No-AMY Group) and a group whose cervical drain fluid amylase levels were measured daily until postoperative day (POD) 7 (AMY Group). The incidence of severe AL was compared between groups. In the AMY Group, we also investigated the association between AL and drain amylase levels. RESULTS: Drain amylase levels were significantly higher in AL-positive cases than in AL-negative cases (P < 0.001). Receiver operating characteristic curve analysis revealed the drain amylase level cut-off value for AL diagnosis was 1800 U/L on POD 2 (Area under the curve = 0.835; P = 0.027). The incidence of ≥ grade III AL was significantly lower in the AMY Group than in the No-AMY Group (2 vs. 10%, P = 0.047). CONCLUSIONS: Cervical drain fluid amylase levels can be a useful screening method for early detection of AL after esophagectomy for esophageal cancer and may help reduce incidence of severe postoperative AL.

Appropriate Candidates for Salvage Esophagectomy of Initially Unresectable Locally Advanced T4 Esophageal Squamous Cell Carcinoma.

BACKGROUND: Standard treatment for unresectable locally advanced esophageal cancer is definitive chemoradiotherapy (dCRT). Although salvage esophagectomy is the only curative treatment available following dCRT failure, the appropriate candidates for salvage esophagectomy remain unclear. PATIENTS AND METHODS: Three hundred seventeen patients who underwent dCRT from April 2004 to December 2016 were stratified into three study groups-a complete response (CR) group, chemotherapy or best supportive care (BSC) group, and salvage esophagectomy group-and compared. We also investigated the clinical outcomes and prognostic factors of salvage esophagectomy. RESULTS: Seventy-one patients (22.4%) achieved CR after dCRT, 18 patients (5.7%) underwent salvage esophagectomy, and 228 patients (71.9%) underwent palliative chemotherapy or BSC. The 5-year overall survival (OS) rates of the CR group, salvage esophagectomy group, and chemotherapy or BSC group were 83.0%, 51.6%, and 1.3%, respectively. Salvage esophagectomy recipients had a worse OS rate than CR patients (p < 0.001) but a better OS rate than those in the chemotherapy or BSC group (p < 0.001). Incomplete resection was the only significant variable associated with poor OS on univariate Cox proportional-hazards analysis (hazard ratio: 7.633, 95% confidence interval: 1.692-34.482; p = 0.008). Patients with tumors in the upper thoracic esophagus were more likely to undergo incomplete resection (p = 0.011). CONCLUSIONS: Patients who achieve R0 resection are good candidates for salvage esophagectomy regardless of their response to dCRT. Those with upper thoracic esophageal tumors are at risk of incomplete resection; careful attention is required when considering these patients for salvage esophagectomy.

Ability of Laparoscopic Gastric Mobilization to Prevent Pulmonary Complications After Open Thoracotomy or Thoracoscopic Esophagectomy for Esophageal Cancer: A Systematic Review and Meta-analysis.

BACKGROUND: Esophagectomy has a high risk of postoperative morbidity, and pulmonary complications are the most common causes of serious morbidity. Thoracoscopic esophagectomy has been reported to reduce postoperative pulmonary complications; however, it remains unclear whether laparoscopic gastric mobilization can reduce the occurrence of postoperative pulmonary complications after open thoracotomy or thoracoscopic esophagectomy. The present meta-analysis assessed the ability of laparoscopic gastric mobilization to prevent postoperative complications after open thoracotomy or thoracoscopic esophagectomy. METHOD: Studies reported between January 2000 and April 2019 in the PubMed and the Cochrane Library databases that analyzed the impact of laparoscopy on postoperative complications were systematically reviewed. In the meta-analysis, data were pooled and the primary outcome was postoperative pulmonary complications. The secondary outcomes were other postoperative complications, operative details, length of hospital stay and postoperative mortality. RESULTS: A total of 13 studies (1915 patients; 1 randomized trial, 1 prospective study and 11 observational studies) were included. Laparoscopic gastric mobilization after open thoracotomy resulted in significantly reduced postoperative pulmonary complications (OR = 0.47, 95% confidence interval (CI): 0.27-0.82, p = 0.008) and postoperative mortality (OR = 0.49, 95%CI: 0.25-0.94, p = 0.03). Similarly, laparoscopic gastric mobilization after thoracoscopic esophagectomy resulted in significantly reduced postoperative pulmonary complications (OR = 0.56, 95%CI: 0.37-0.84, p = 0.005) and anastomotic leakage (OR = 0.59, 95%CI: 0.39-0.91, p = 0.02). CONCLUSIONS: Laparoscopic gastric mobilization could be recommended for reducing postoperative pulmonary complications after esophagectomy irrespective of the thoracic approach.

Contrasting Roles of Programmed Death-Ligand 1 Expression in Tumor and Stroma in Prognosis of Esophageal Squamous Cell Carcinoma.

The assessment of programmed death-ligand 1 (PD-L1) expression in esophageal squamous cell carcinoma (ESCC) has become increasingly important with the rise of immune checkpoint inhibitors (ICIs). However, challenges persist, including subjective interpretation and the unclear significance of staining intensity, as well as contrasting roles in tumoral and stromal regions. Our study enhances the understanding of PD-L1 in ESCCs by analyzing its expression in tumors and stroma with H-scores, highlighting its distinct clinicopathological impacts. In a retrospective cohort of 194 ESCC specimens from surgical resection, we quantified PD-L1 expression in tumoral and stromal compartments using H-scores, analyzing whole slide images with digital pathology analysis software. Kaplan-Meier analysis demonstrated that higher PD-L1 expression is significantly associated with improved postoperative overall survival (OS) and recurrence-free survival (RFS) in both tumoral and stromal areas. Multivariable analysis identified high tumoral PD-L1 expression as an independent prognostic factor for prolonged OS and RFS (HR = 0.47, p = 0.007; HR = 0.54, p = 0.022, respectively). In a separate analysis, high stromal PD-L1 expression was found to correlate with less advanced pathological stages and a prolonged response to cytotoxic chemotherapy, with no similar correlation found for ICI treatment response. This study reveals PD-L1's contrasting role in the ESCC tumor immune microenvironment, impacting prognosis, tumor stage, and treatment response.

Tissue Oxygen Saturation during Gastric Tube Reconstruction with Cervical Anastomosis for Esophagectomy: A Case Series.

BACKGROUND: One cause of anastomotic leakage after radical esophagectomy is blood flow insufficiency at the cervical anastomosis site. . METHODS: Eighteen patients, who underwent radical esophagectomy with gastric tube reconstruction, were studied. The regional tissue oxygen saturation (rSO2) was measured at the tip (point pre 0) and 2, 4, and 6 cm on the distal side of the tip (point pre 1, pre 2, and pre 3, respectively) before the gastric tube was raised to the cervical site through the retrosternal route. After that, rSO2 was measured at the tip, 2 and 4 cm on the distal side of the tip (points post 0, post 1, and post 2), the actual anastomotic site (point AN), and the chest skin as an indicator of whole-body oxygenation. The relationship between rSO2 scores and the rate of anastomotic leakage was determined. RESULTS: The mean rSO2 at pre 0, pre 1, pre 2, and pre 3 were 48.9%, 52.3%, 54.8%, and 56.9%, respectively (p < 0.05). The mean rSO2 at post 0, post 1, and post 2 were 47.8%, 50.5%, and 52.3%, respectively, and the rSO2 at point AN was 52.1%.Anastomotic leakage was found in 6 patients. The rSO2 at points pre 0, pre 1, and pre 2, post 0 and point AN were significantly lower in patients with anastomosis leakage than those without (p < 0.05). CONCLUSION: Tissue oxygen saturation monitoring was a useful indicator of blood flow insufficiency in the gastric tube during radical esophagectomy.

Difficult to treat esophageal perforation after endoscopic balloon dilation for stenosis due to endoscopic submucosal dissection followed by chemoradiotherapy: A case report.

INTRODUCTION AND IMPORTANCE: There is no clear consensus on a specific treatment for esophageal perforation. The surgical approach is deemed necessary for local severe infection and pleural contamination requiring debridement. PRESENTATIONS OF CASE: We have reported herein the case of a patient with esophageal perforation with severe mediastinal and thoracic abscess after endoscopic balloon dilation for stenosis due to endoscopic submucosal dissection and chemoradiotherapy. A surgical approach with primary closure was performed, but not found effective; while conservative treatment with mediastinal drainage via posterior neck and recovery of nutritional status was found to be effective. For the recovery of nutritional status, enteral nutrition was assessed using a polymeric formula through a percutaneous endoscopic gastrojejunostomy tube. DISCUSSION: Esophageal perforation is a life-threatening condition. Iatrogenic injuries are the frequent cause of esophageal perforation. For esophageal perforation, not only surgical interventions but also conservative treatments including various endoscopic approaches have been performed. If the inflammation is not localized, surgical intervention is often needed; however, if the patient's general condition is stable, conservative treatment with drainage, antibiotics, and nutritional management may be considered, even in cases of esophageal perforation. CONCLUSIONS: Esophageal perforation with a large perforation site with widespread inflammation can be improved with proper thoracic and mediastinal drainage and adequate nutrition support if the patient's condition is mild.
