Large esophageal schwannoma: En-bloc resection with primary closure by esophagoplasty.

ABSTRACT:

Background

Gastrointestinal schwannomas are submucosal tumors accounting for 2-7% of mesenchymal gastro-intestinal neoplasms; the stomach being the most common site. Esophageal schwannomas are more frequent in women, and are usually located in the upper to mid portion. Dysphagia is the main presenting symptom. A definitive diagnosis requires confirmation by histopathological and immunohistochemical studies.

Case presentation

A 50-year-old healthy lady, presented with gradual increasing onset of dyspnea, with minimal dysphagia to solid food, over a period of several years. Enhanced CT scan of the chest revealed a well-defined soft tissue mass arising from the proximal third of the esophagus, measuring 7.8?×?5.4?x?10.5?cm. Esophagogastric endoscopy with ultrasonography showed an elevated, smooth surface lesion, arising from the submucosal layer of the esophagus, with a hypervascular mucosa. Enucleation of this large tumor, with preservation of the overlying mucosa, was difficult to accomplish due to its large size. Making use of a dilated proximal esophageal segment, total en-bloc excision of the mass rendered a 15?cm esophagotomy gap, which was easily closed, in two layers, without affecting the overall caliber thus achieving a good esophagoplasty result. Histologically, abundance of spindle-shaped cells with positive S-100 proteins, confirmed the diagnosis of esophageal schwannoma.

Conclusion

Variations in mesenchymal gastrointestinal tumors is vast, rendering diagnosis by radiology alone difficult. As such, characteristic histologic and immunostaining features are cornerstones in precise diagnosis of esophageal schwannomas. Despite being rare in incidence, symptomatic esophageal schwannoma lesions can be excised entirely, with low rate of recurrence and favorable overall outcomes.

Project description:Objectives:This study sought to determine the clinical and pathological factors associated with perioperative morbidity, mortality and oncological outcomes after multivisceral en bloc resection in patients with colorectal cancer.Methods:Between January 2009 and February 2014, 105 patients with primary colorectal cancer selected for multivisceral resection were identified from a prospective database. Clinical and pathological factors, perioperative morbidity and mortality and outcomes were obtained from medical records. Estimated local recurrence and overall survival were compared using the log-rank method, and Cox regression analysis was used to determine the independence of the studied parameters. ClinicalTrials.gov: NCT02859155.Results:The median age of the patients was 60 (range 23-86) years, 66.7% were female, 80% of tumors were located in the rectum, 11.4% had stage-IV disease, and 54.3% received neoadjuvant chemoradiotherapy. The organs most frequently resected were ovaries and annexes (37%). Additionally, 30.5% of patients received abdominoperineal resection. Invasion of other organs was confirmed histologically in 53.5% of patients, and R0 resection was obtained in 72% of patients. The overall morbidity rate of patients in this study was 37.1%. Ureter resection and intraoperative blood transfusion were independently associated with an increased number of complications. The 30-day postoperative mortality rate was 1.9%. After 27 (range 5-57) months of follow-up, the mortality and local recurrence rates were 23% and 15%, respectively. Positive margins were associated with a higher recurrence rate. Positive margins, lymph node involvement, stage III/IV disease, and stage IV disease alone were associated with lower overall survival rates. On multivariate analysis, the only factor associated with reduced survival was lymph node involvement.Conclusions:Multivisceral en bloc resection for primary colorectal cancer can be performed with acceptable rates of morbidity and mortality and may lead to favorable oncological outcomes.
