  • Mitral valve nonbacterial thrombotic endocarditis: a rare multi-surgery-tolerant survivor of Trousseau's syndrome.
    Surgical case reports, 2018
    Co-Authors: Yoshiharu Soga, Kaoru Taira, Akira Sugimoto, Manabu Kurosawa, Hiromasa Kira, Kazuhiko Doi, Akira Nakano, Yoshihiro Himura
    Abstract:

    Few previous reports have documented cases of nonbacterial thrombotic endocarditis associated with Trousseau’s syndrome for which surgery proved possible for both the primary tumor and the cardiac lesion. The effectiveness of direct oral anticoagulants in patients with Trousseau’s syndrome has also received scant attention. A 69-year-old man with repeated episodes of cerebral infarction was diagnosed as having nonbacterial thrombotic endocarditis after mitral valve replacement surgery. Stroke recurred preoperatively under apixaban administration. A Stomach Biopsy also identified gastric adenocarcinoma, and gastric surgery was performed on the 40th postoperative day. The patient was discharged from the hospital and has been free of thromboembolism under a regime of subcutaneous heparin self-injection thereafter. We have reported a rare multi-surgery-tolerant survivor of Trousseau’s syndrome in whom subcutaneous heparin injection was useful for preventing thromboembolic events over a long period.

  • simultaneous early adenocarcinoma and mucosa associated lymphoid tissue malt lymphoma of the Stomach associated with helicobacter pylori infection
    Gastric Cancer, 2003
    Co-Authors: Takehiro Sakai, Yuta Ogura, Junichi Narita, Takemichi Suto, Daisuke Kimura, Susumu Ainai, Hajime Fujita, Mitsuru Kamada
    Abstract:

    The simultaneous association of gastric carcinoma with gastric lymphoma is a rare event. Recent studies have suggested that not only gastric cancer but also primary gastric lymphomas, especially those of mucosa-associated lymphoid tissue (MALT) type, are associated with Helicobacter pylori infection. We report on a 51-year-old woman who was referred to our hospital for the evaluation of abnormal shadows revealed by an upper gastrointestinal radiography series. Endoscopy of the upper gastrointestinal tract revealed early cancer in the middle body of the Stomach. Biopsy of the lesion subsequently proved it to be a signet-ring cell carcinoma. Total gastrectomy was performed, under a diagnosis of early gastric carcinoma. The resected specimen revealed two grossly separate lesions. Histological examination confirmed that the gastric body lesion was compatible with early moderately differentiated tubular adenocarcinoma of type 0-IIc, while the lesion of the fundus corresponded to MALT lymphoma. H. pylori was detected, and chronic gastritis was also present in the resected gastric specimen. H. pylori infection may have played a major role in the development of both the MALT lymphoma and the adenocarcinoma of the Stomach in this patient.

  • efficacy of a three dimensional printed training simulator for endoscopic Biopsy in the Stomach
    Gut and Liver, 2018
    Co-Authors: S S Lee, Ji Yong Ahn, Minkyu Han, Gin Hyug Lee, Kee Wook Jung, Jeong Hoon Lee, Do Hoon Kim, Kee Don Choi, Ho June Song, Hwoonyong Jung
    Abstract:

    Background/Aims We used three-dimensional (3D) printing technology to create a new Biopsy simulator for the Stomach and investigated its efficacy and realism in endoscopic Biopsy training. Methods A novel Stomach Biopsy simulator, with 10 Biopsy sites, was produced using a 3D printer. We enrolled 26 participants, including 10 residents, six first-year fellows, five second-year fellows, and five faculty members. We recorded and reviewed five training sessions and evaluated the simulator with questionnaires using a 7-point Likert scale. Results The mean completion time (seconds) was 244.8±11.5 for the residents, 107.9±33.4 for the first-year fellows, 106.8±20.1 for the second-year fellows, and 103.8±19.2 for the faculty members. The completion time became shorter with repetition and was significantly lower for residents by the fifth trial (first trial, 347.0±159.5; fifth trial, 169.6±57.7; p=0.007). The faculty members strongly agreed that the simulator realistically reflected endoscopic handling and was reasonable for endoscopic training (scores of 6.2±0.8 and 6.4±0.9, respectively). Importantly, experienced endoscopists reported that the difficulty levels of the 10 Biopsy sites in the simulator were a realistic match for the actual Stomach. Conclusions This endoscopic Biopsy simulator created using a 3D printer is a realistic and useful method to improve the Biopsy skills of trainee endoscopists.
