Abstract The esophagus traverses three body compartments (neck, thorax, and abdomen) and is surrounded at each level by vital organs. Injuries to the esophagus may be classified as foreign body ingestion, caustic ingestion, esophageal perforation, and esophageal trauma. These lesions can be life-threatening either by digestive contamination of surrounding structures in case of esophageal wall breach or concomitant damage of surrounding organs. Early diagnosis and timely therapeutic intervention are the keys of successful management.

Background and study aims Esophageal cancer (EC) is one of the most lethal malignancies worldwide. Staging of EC is performed with computed tomography (CT), positron-emission tomography (PET), and endoscopic ultrasonography (EUS). Patient management mostly depends on lymph node status. Compared to histopathology, the accuracy of EUS for T and N parameters is about 85 % and 75 %, respectively. Errors in staging may change prognosis. The aim of this study was to assess the role of EUS in T2-N0 EC considering the experience of two high-volume digestive endoscopic centers. Methods Two prospectively collected databases were queried to identify all patients with EC, staged as cT2N0 by EUS, with no distant metastases at CT/PET scan and who underwent transthoracic esophagectomy. Preoperative EUS staging (cTNM) was compared to histopathology of the surgical specimen (pTNM) to evaluate accuracy. Results Of 729 consecutive patients with EC between January 2011 and September 2018, 72 (49 men) had cT2N0 disease. CT and PET scans confirmed the absence of distant metastasis. In 43 of 72 patients (60 %), the evaluation was correct, 23 of 72 (31,7 %) were understaged, and six of 72 patients (8,3 %) were overstaged. Among the understaged patients, eight were understaged by tumor depth (35 %), seven by nodal involvement (30 %), and eight by both (35 %). All six patients who were overstaged had T1b-N0 disease. EUS accuracy was 77 % in staging for tumor depth and 82 % in staging for nodal metastases. The positive predictive value (PPV) for cT2N0 EC was 60 % (43 pT2N0 /72 cT2N). Conclusions The accuracy of EUS staging of T2N0 EC is low, with only 60 % of patients undergoing appropriate therapy based on histopathology.

Background: Malignant rhabdoid tumor is a kidney childhood tumor with aggressive clinical behavior and a wide spectrum of histologic, immunophenotypic, and cytogenetic findings. Extra-renal rhabdoid tumors have been reported in the brain, breast, liver, pancreas, bladder, vulva, prostate, and colon. To date, only nine cases of esophageal rhabdoid tumors have been described, all in patients over 50-year old. We add to the current literature the case of an esophageal, poorly differentiated rhabdoid tumor occurring in a young man.Case Report: A 24-year-old man was referred for progressive dysphagia, retrosternal pain, nausea, and food regurgitation. Esophagogastroduodenoscopy showed an obstructing neoplastic lesion of the distal esophagus associated with Barrett's esophagus. Biopsies revealed undifferentiated esophageal cancer with epithelial morphology and immunohistochemistry positive for CK pan, CK 7 e CK 8-18. Minimally invasive esophagectomy and extended lymphadenectomy was performed. Histopathology showed a poorly differentiated tumor, with morphologic characteristics of rhabdoid tumor, central necrosis and transmural infiltration of the esophageal wall. Definitive immunohistochemistry was positive for vimentin, CD34, synaptophysin, and INI1.Conclusion: Esophageal rhabdoid tumor is extremely rare and highly aggressive, with only few patients alive at 1 year follow-up, according to our review. Immunohistochemistry characterization is critical for diagnosis. Minimally invasive esophagectomy is an appealing and possibly less morbid option compared to open surgery. However, further research is needed to investigate the potential role of targeted immunotherapy.

Abstract Background Traumatic, non-iatrogenic esophageal injuries, despite their rarity, are associated with significant morbidity and mortality. The optimal management of these esophageal perforations remains largely debated. To date, only a few small case series are available with contrasting results. The purpose of this study was to examine a large contemporary experience with traumatic esophageal injury management and to analyze risk factors associated with mortality. Methods This National Trauma Data Bank (NTDB) database study included patients with non-iatrogenic esophageal injuries. Variables abstracted were demographics, comorbidities, mechanism of injury, Abbreviated Injury Scale (AIS), esophageal Organ Injury Scale (OIS), Injury Severity Score (ISS), level of injury, vital signs, and treatment. Multivariate analysis was used to identify independent predictors for mortality and overall complications. Results A total of 944 patients with non-iatrogenic esophageal injury were included in the final analysis. The cervical segment of the esophagus was injured in 331 (35%) patients. The unadjusted 24-h mortality (8.2 vs. 14%, p = 0.008), 30-day mortality (4.2 vs. 9.3%, p = 0.005), and overall mortality (7.9 vs. 13.5%, p = 0.009) were significantly lower in the group of patients with a cervical injury. The overall complication rate was also lower in the cervical group (19.8 vs. 27.1%, p = 0.024). Multilogistic regression analysis identified age >50, thoracic injury, high-grade esophageal injury (OIS IV–V), hypotension on admission, and GCS

BACKGROUND:Early suspicion, diagnosis, and timely treatment of anastomotic leak after esophagectomy is essential. Retrospective studies have investigated the role of C-reactive protein (CRP) as early marker of anastomotic leakage. The aim of this systematic review and meta-analysis was to evaluate the predictive value of CRP after esophageal resection. METHODS:A literature search was conducted to identify all reports including serial postoperative CRP measurements to predict anastomotic leakage after elective open or minimally invasive esophagectomy. Fully Bayesian meta-analysis was carried out using random-effects model for pooling diagnostic accuracy measures along with CRP cut-off values at different postoperative day. RESULTS:Five studies published between 2012 and 2018 met the inclusion criteria. Overall, 850 patients were included. Ivor-Lewis esophagectomy was the most common surgical procedure (72.3%) and half of the patients had squamous-cell carcinoma (50.4%). The estimated pooled prevalence of anastomotic leak was 11% (95% CI = 8-14%). The serum CRP level on POD3 and POD5 had comparable diagnostic accuracy with a pooled area under the curve of 0.80 (95% CIs 0.77-0.92) and 0.83 (95% CIs 0.61-0.96), respectively. The derived pooled CRP cut-off values were 17.6 mg/dl on POD 3 and 13.2 mg/dl on POD 5; the negative likelihood ratio were 0.35 (95% CIs 0.096-0.62) and 0.195 (95% CIs 0.04-0.52). CONCLUSION:After esophagectomy, a CRP value lower than 17.6 mg/dl on POD3 and 13.2 mg/dl on POD5 combined with reassuring clinical and radiological signs may be useful to rule-out leakage. In the context of ERAS protocols, this may help to avoid contrast radiological studies, anticipate oral feeding, accelerate hospital discharge, and reduce costs.
