AIM:Gastrointestinal autonomic nerve tumors areuncommon stromal tumors of the intestinal tract.Theirhistological appearance is similar to that of othergastrointestinal stromal tumors.We report two cases andperformed an analysis of the literature by comparing ourfindings with the available case reports in the medicalliterature.METHODS:Two patients were admitted with abdominaltumor masses.One occurred in the stomach with largemultiple liver metastases and the second originated inMeckel’s diverticulum.The latter site has never beenreported previously.Both patients underwent surgery.Inone patient gastrectomy,right liver resection and colontransversum resection were performed to achieveaggressive tumor debulking.In the other patient the tumorbearing diverticulum was removed.RESULTS:Postoperative recovery of both patients wasuneventful.Histological examination,immunohistochemicalanalysis and electron microscopy revealed the diagnosisof a gastrointestinal autonomic nerve tumor.The patientwith the tumor in Meckel’s diverticulum died 6 mo aftersurgery because of pneumonia.The patient with livermetastases have been alive 13 years after initial tumordiagnosis and 7 years after surgery with no evidence oftumor progression.In light of our results,we performed athorough comparison with available literature reports.CONCLUSION:Radical surgical resection of gastrointestinalautonomic nerve tumors seems to be the only availablecurative approach to date,and long term survival is possibleeven in large metastasized tumors.
AIM: Gastrointestinal autonomic nerve tumors areuncommon stromal tumors of the intestinal tract. Theirhistological appearance is similar to that of other ofgastrointestinal stromal tumors. We report two cases andperformed an analysis of the literature by managing our together with the available case reports in the medical literature. METHODS: Two patients were admitted with abdominal metastases masses. Onene occurred in the stomach with large multiple liver metastases and the second originated in Meckel’s diverticulum. latter latter has been been previouslyported.Both patients underwent surgery. Oneone gastrectomy, right liver resection and colon transversum resection were performed to achieve agressive tumor debulking.In the other patient the tumorbearing diverticulum was removed.RESULTS: Postoperative recovery of both patients wasuneventful. Histological examination, immunohistochemicalanalysis and electron microscopy revealed the diagnosisof a gastrointestinal autonomic nerve tumor.The patientwith the tumor in Meckel’s diverticulum died 6 mo aftersurgery because of pneumonia. The patient with livermetastases have been been alive 13 years after initial tumordiagnosis and 7 years after surgery with no evidence of metastatic. In the light of our results, we performed athorough comparison with available literature reports . CONCLUSION: Radical surgical resection of gastrointestinalautonomic nerve tumors seems to be the only availablecurative approach to date, and long term survival is possibleeven in large metastasized tumors.
