Objective: To study the clinical, endoscopy and pathogical characteristics of colorectal cancer at Da Nang Hospital. Methods: A retrospectively descriptive study, performed from 01/01/2016 to 31/12/2017 at Da Nang Hospital. Results: During two years, there were 205 cases of colorectal cancer patients hospitalized to Da Nang Hospital. Male: 59.51%, female: 40.49%, mean age: 65.8 ± 16.07. Male is higher than female, male/ female ratio is 1.4/1. The period from the first symptoms to admission < 3months predominated (83.8%). The predominant symptoms: Abdominal pain (85.85%), bloody stool (63.41%), defecation (62.44%), anemia (34.63%), weight loss (25.85%), fatigue (17.56%), abdominal distention (12.19%), nausea and vomiting (5.36%). Location of Lesions: Rectum (43.42%), sigmoid colon (20%), right colon (10.73%),cecum (10.73%), transverse colon (7.80%), left-colon (7.32%). Type of lesion on endoscopy: Exophytic (63.41%), ulceration-Exophytic (21.95%), ulceration (7.32%), polyp chemotherapy (7.32). Tumor size: ≥ 3/4 perimeter (39%), occupying the whole circumference (37.0%), occupying ≥ 1/2 perimeter (15.6%), accounting for 1/4 Perimeter (8.4%). The colon completely narrowed rate: 70.73%., incompletely was 29.27%. Histopathological classification: adenocarcinoma (85.85%), Mucinous adenocarcinoma: (9.27%) and non-differentiated epithelial carcinoma was 4.88%. Conclusion: Colorectal cancer was quite popular and was usually detected at advanced stages.Therefore, screening for subjects with risk factors for early detection and treatment is recommended. Key words: Colorectal cancer, endoscopy, pathogical characteristics...
Benign tumors of the esophagus are rare. Among them, leiomyomas are common. Surgical enucleation is indicated in cases, which have symptoms or large tumors. The enucleation through video assisted thoracoscopic surgery has been developed as a preferred approach for the majority of lesions in recent years. However, the complete thoracoscopic enucleation for an esophagus leiomyoma at the level of the azygos vein without cutting the vein and nor using artificial pneumothorax by CO 2 insufflations is a challenge for thoracic surgeons. This case report was a 64-year-old female who presented dysphagia and chest pain. Chest computed tomography and esophageal endoscopy displayed an esophageal mass. We used complete thoracoscopic enucleation to treat this condition. The tumor was at the level of the azygos vein. Therefore, it was difficult to remove the tumor without cutting the azygos vein without utilizing the artificial pneumothorax. However, we enucleated it completely with no complications. The complete thoracoscopic enucleation of the esophageal leiomyoma at the level of the azygos vein without cutting the vein without using the artificial pneumothorax should be applied. A methylene blue swallowing study is an alternative method to a barrium swallowing study while the chest tube is still placed in the pleural space.
