| 1 | Endoscopic submucosal dissection for early esophageal neoplasms using the stag beetle knife显示文摘AIM To determine short-and long-term outcomes of endoscopic submucosal dissection(ESD) using the stag beetle(SB) knife, a scissor-shaped device.METHODS Seventy consecutive patients with 96 early esophageal neoplasms, who underwent ESD using a SB knife at Kure Medical Center and Chugoku Cancer Center, Japan, between April 2010 and August 2016, were retrospectively evaluated. Clinicopathological characteristics of lesions and procedural adverse events were assessed. Therapeutic success was evaluated on the basis of en bloc, histologically complete, and curative or non-curative resection rates. Overall and tumor-specific survival, local or distant recurrence, and 3-and 5-year cumulative overall metachronous cancer rates were also assessed.RESULTS Eligible patients had dysplasia/intraepithelial neoplasia(22%) or early cancers(squamous cell carcinoma, 78%). The median procedural time was 60 min and on average, the lesions measured 24 mm in diameter, yielding 33-mm tissue defects. The en bloc resection rate was 100%, with 95% and 81% of dissections deemed histologically complete and curative, respectively. All procedures were completed without accidental incisions/perforations or delayed bleeding. During follow-up(mean, 35 ± 23 mo), no local recurrences or metastases were observed. The 3-and 5-year survival rates were 83% and 70%, respectively, with corresponding rates of 85% and 75% for curative resections and 74% and 49% for noncurative resections. The 3-and 5-year cumulative rates of metachronous cancer in the patients with curative resections were 14% and 26%, respectively.CONCLUSION ESD procedures using the SB knife are feasible, safe, and effective for treating early esophageal neoplasms, yielding favorable short-and long-term outcomes. | Toshio Kuwai Toshiki Yamaguchi Hiroki Imagawa Ryoichi Miura Yuki Sumida Takeshi Takasago Yuki Miyasako Tomoyuki Nishimura Sumio Iio Atsushi Yamaguchi Hirotaka Kouno Hiroshi Kohno Sauid Ishaq | 2018 | World Journal of Gastroenterology2018，24，15： | 7 |
| 2 | Gastric and enteric anisakiasis successfully treated with Gastrografin therapy: A case report显示文摘We report a case of a 59-year-old woman who was diagnosed with gastric and small intestinal anisakiasis, which was successfully treated with endoscopic extraction and Gastrografin therapy. She was admitted to our hospital with epigastric pain and vomiting one day after eating raw fish. She exhibited tenderness in the epigastrium without obvious rebound tenderness or guarding. Computed tomography (CT) demonstrated segmental edema of the intestinal wall with proximal dilatation and a small number of ascites. Because enteric anisakiasis was suspected based on the patient's history of recent raw fish consumption and abdominal CT, we performed gastroscopy and confirmed that nine Anisakis larvae were attached to the gastric mucosa. All of the Anisakis larvae were extracted via endoscopy, and the patient was diagnosed with gastric and enteric anisakiasis. Additionally, in the hospital, we performed ileography twice using Gastrografin, which led to shortened hospital stay. Based on the clinical results of this case, we suggest that Gastrografin therapy is a safe, convenient, and useful method to extract enteric Anisakis larvae. | Hiroki Fujikawa Toshio Kuwai Toshiki Yamaguchi Ryoichi Miura Yuki Sumida Takeshi Takasago Yuki Miyasako Tomoyuki Nishimura Sumio Iio Hiroki Imagawa Atsushi Yamaguchi Hirotaka Kouno Hiroshi Kohno | 2018 | World Journal of Gastrointestinal Endoscopy2018，10，3： | 1 |
| 3 | Safety and efficacy of self-expandable metallic stents in malignant small bowel obstructions显示文摘In this report, we present 3 cases of malignant small bowel obstruction, treated with palliative care using endoscopic self-expandable metallic stent(SEMS) placement, with the aim to identify the safety and efficacy of this procedure. Baseline patient characteristics, procedure methods, procedure time, technical and clinical success rates, complications, and patient outcomes were obtained. All 3 patients had pancreatic cancer with small bowel strictures. One patient received the SEMS using colonoscopy, while the other 2 patients received SEMS placement via double balloon endoscopy using the through-the-overtube technique. The median procedure time was 104 min. The technical and clinical success rates were 100%. Post-treatment, obstructive symptoms in all patients improved, and a low-residue diet could be tolerated. All stents remained within the patients until their deaths. The median overall survival time(stent patency time) was 76 d. SEMS placement is safe and effective as a palliative treatment for malignant small bowel obstruction. | Akiyoshi Tsuboi Toshio Kuwai Tomoyuki Nishimura Sumio Iio Takeshi Mori Hiroki Imagawa Toshiki Yamaguchi Atsushi Yamaguchi Hirotaka Kouno Hiroshi Kohno | 2016 | World Journal of Gastroenterology2016，22，40： | 1 |
