Gastrointestinal cancers
Published in Ruijiang Li, Lei Xing, Sandy Napel, Daniel L. Rubin, Radiomics and Radiogenomics, 2019
A further study by Ma et al. developed a radiomics signature based on pre-treatment CT images to distinguish Borrmann type IV gastric cancer (GC) from primary gastric lymphoma (PGL). The radiomics signature showed a higher area under the curve (AUC) (0.886), sensitivity, and specificity than the subjective imaging findings. Moreover, combining the radiomics data with subjective CT findings further improved the discrimination performance (AUC: 0.903; specificity: 1; sensitivity: 0.7) (Ma et al. 2017). In addition, as the first study using 3D radiomics features for differential diagnosis in gastric malignancy, the results of this study support the previous finding that using 3D radiomics features improved the discrimination accuracy compared with using 2D features. By taking all of the available slices into consideration, it provides a more comprehensive view of the whole tumor.

There are numerous case reports describing the efficacy of OverStitch suturing in the management of rare types of fistulas. Benin et al. in 2012 reported successful closure of a persistent esophagopleural fistula from Boerhaave syndrome with OverStitchTM after failed closure with endoclip and stenting [41]. In 2017, Andrews et al. reported closure of a gastropleural fistula in a patient post gastric sleeve [42]. Utilizing OverStitchTM, closure of a cholecystoduodenal fistula in a patient with Crohn’s disease [43] and a gastroretroperitoneal fistula from primary gastric lymphoma were successfully achieved [44]. In a multimodality approach, Chon et al. described a case of successful closure of a gastro-pulmonary fistula utilizing Overstitch suturing device and endoscopic vacuum therapy [45]. As mentioned earlier, there are limited data in regards to OverStitch Sx; however Maselli et al., in a multicenter prospective trial of 107 patients, reported the success rate of OverStitch Sx in fistula closure, perforation repair, post-op leak closure and stent fixation as 61.5%, 94.4%, 80%, and 86.6%, respectively [26].
