| 1 | Endoscopic retrieval of a gastric trichobezoar显示文摘A 9-year-old girl presented with a chief complaint of abdominal pain. Esophagogastroduodenal endoscopy (EGD) identifi ed a long and large gastric trichobezoar extending into the duodenum. We attempted endoscopic retrieval after informed consent was obtained from the patient's mother. Initially, a gasper with 5-prolongs, com monly used for retrieval of endoscopically excised poly ps, failed to remove the whole trichobezoar. When a net was used instead, it proved impossible to remove the trichobezoar completely. Therefore, we withdrew the scope from the mouth, leaving the net grasping the tri co bezoar firmly in the stomach. Subsequently, we were able to retrieve about 70% of the trichobezoar manually by grasping the snare part of the net directly. A second pass found no deep laceration or perforation endoscopically. The remaining trichobezoar was completely retrieved with the net. The procedure was completed within 15 min. The retrieved specimens were34 cm in length and 100 g in weight. The patient was discharged uneventfully 5 d thereafter. She was advised to visit a psychiatrist to avoid suffering from a relapse. Follow-up EGD showed no trichobezoar, and the patient' s frontal hair grew back. | Hironori Konuma Kuangi Fu Takashi Morimoto Takayoshi Shimizu Yuko Izumi Satoko Shiyanagi Masahiko Urao Akihisa Miyazaki Sumio Watanabe | 2011 | World Journal of Gastrointestinal Endoscopy2011，3，1： | 4 |
| 2 | Alpha-fetoprotein-producing colon cancer with atypical bulky lymph node metastasis显示文摘Alpha-fetoprotein (AFP)-producing colorectal cancer is extremely rarely reported until now. All of the reported cases harboring synchronous hematogenous spread including liver and/or lung metastasis had a poor prognosis and died within 12 mo. We here describe a 71-year old man with AFP-producing colon cancer who presented with an unusual bulky lymph node metastasis instead of hematogenous spread. He underwent adjuvant chemotherapy in addition to curative surgical resection, which prolonged his survival. | Kuangi Fu Akihiro Kobayashi Norio Saito Yasushi Sano Shigeharu Kato Hiroaki Ikematsu Takahiro Fujimori Yasushi Kaji Shigeaki Yoshida | 2006 | World Journal of Gastroenterology2006，12，47： | 3 |
| 3 | Mallory-Weiss tear during gastric endoscopic submucosal dissection显示文摘A 78-year-old woman was referred to our department for treatment of an early gastric cancer. Esophagogastroduodenoscopy (EGD) demonstrated a flat elevated lesion and a polypoid lesion on the greater curvature of the antrum. Histological analysis of, endoscopic biopsy samples taken from these lesions revealed an adenocarcinoma and a hyperplastic polyp, respectively. ESD was conducted for removal of the lesions. Carbon dioxide (CO2) in- stead of room air was used for insufflation, and the patient was adequately sedated without struggling or vomiting during the treatment. No significant bleeding from the lesion was observed during ESD, but fresh blood was identified endoscopically. Surprisingly, a Mallory- Weiss tear with active bleeding was detected on the lesser curvature of the gastric corpus. A total of eight hemoclips were applied for hemostasis. Both lesions were completely removed en bloc, and no bleeding or perforation developed after ESD. Histologically, the first lesion was apapillary carcinoma limited to the mucosal layer and without lymphovascular invasion or involvement of the surgical margins, while the second lesion was a benign hyperplastic polyp. | Hiroki Hongou Kuangi Fu Hiroya Ueyama Taiji Takahashi Tsutomu Takeda Akihisa Miyazaki Sumio Watanabe | 2011 | World Journal of Gastrointestinal Endoscopy2011，3，7： | 2 |

| 5 | Combination of concurrent endoscopic submucosal dissection and modified peroral endoscopic myotomy for an achalasia patient with synchronous early esophageal neoplasms显示文摘Achalasia is generally accepted as a condition associated with an increased risk for developing esophageal squamous cell carcinoma. In our paper, we introduced an achalasia patient combined with synchronous early esophageal neoplasms. We performed a combination of concurrent endoscopic submucosal dissection(ESD) and peroral endoscopic myotomy(POEM). No complications other than postoperative pain that needed morphine treatment for two days had occurred. Dysphagia was significantly improved. Neither reflux nor cough occurred. The short-term efficacy and safety of our case is favorable and suggests that concurrent ESD and POEM could be a treatment option to such patients. | Sha Shi Kuangi Fu Xin-Qian Dong Yu-Jing Hao Sen-Lin Li | 2017 | World Journal of Gastrointestinal Endoscopy2017，9，2： | 1 |
| 6 | A novel endoscopic ablation of gastric antral vascular ectasia显示文摘An 80-year-old woman was admitted to our hospital because of tarry stool with iron deficiency anemia. Her past history included autoimmune hepatitis. Esophagogastroduodenal endoscopy was performed to investigate the bleeding source and revealed multiple linear gastric vascular malformations in the antrum and cardia, compatible with Gastric antral vascular ectasia (GAVE). Endoscopic ablation was carried out with the tip of the hot biopsy forceps without opening at soft coagulation mode of 80W. The patient tolerated the procedure well and there were no complications associated with endoscopic therapies. After two sessions of endoscopic ablation her anemia improved to around 10 g/dL, an increase of 3.6 g/dL. Various endoscopic treatments have been described to manage GAVE. The most popular is argon plasma coagulation (APC), although APC is associated with over-distension induced by the argon plasma gas. To avoid over-distension and to reduce the abdominal discomfort/pain of this patient,we have used hot biopsy forceps instead of APC. Our case suggests that this procedure is effective, easy and convenient,as no special equipment or skill is necessary. | Masae Komiyama Kuangi Fu Takashi Morimoto Hironori Konuma Toshifumi Yamagata Yuko Izumi Akihisa Miyazaki Sumio Watanabe | 2010 | World Journal of Gastrointestinal Endoscopy2010，2，8： | 0 |
| 7 | Youngest case of an early gastric cancer after successful eradication therapy显示文摘A 28-year-old woman visited our clinic with a chief complaint of epigastralgia. She had received successful Helicobacter pylori (H. pylori ) eradication therapy 5 years before. We repeated esophagogastroduodenoscopy, and a discolored depressed area with reddish spots and converging folds, 20 mm in size, was detected. No atrophic change including intestinal metaplasia or nodular gastritis was seen endoscopically. Two endoscopic biopsies revealed undifferentiated adenocarcinoma. No H. pylori was found, and the 13 C-urea breath test was also negative. Abdominal computed tomography demonstrated no nodal involvement, distant metastasis or fluid collection. She underwent a laparoscopyassisted distal gastrectomy. Histologically, the resected specimen revealed an early undifferentiated gastric cancer that had invaded deeply into the submucosal layer. Nodal involvement was histologically confirmed.No atrophic change or H. pylori infection was evident histologically. This is the youngest patient ever reported to have developed a node-positive early gastric cancer after eradication of H. pylori . | Hironori Konuma Ichiro Konuma Kuangi Fu Satoshi Yamada Yutaka Suzuki Akihisa Miyazaki | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，6： | 0 |
