| 1 | Ultrasound-guided vs endoscopic ultrasound-guided fine-needle aspiration for pancreatic cancer diagnosis显示文摘AIM: To clarify the effectiveness and safety of endo- scopic ultrasound-guided fine-needle aspiration (EUS-FNA) for the diagnosis of pancreatic cancer (PC). METHODS: Patients who were diagnosed with unresectable, locally advanced or metastatic PC between February 2006 and September 2011 were selected for this retrospective study. FNA biopsy for pancreatic tumors had been performed percutaneously under extracorporeal ultrasound guidance until October 2009; then, beginning in November 2009, EUS-FNA has been performed. We reviewed the complete medical records of all patients who met the selection criteria for the following data: sex, age, location and size of the targeted tumor, histological and/or cytological findings, details of puncture procedures, time from day of puncture until day of definitive diagnosis, and details of severe adverse events. RESULTS: Of the 121 patients who met the selection criteria, 46 had a percutaneous biopsy (Group A) and 75 had an EUS-FNA biopsy (Group B). Adequate cytological specimens were obtained in 42 Group A patients (91.3%) and all 75 Group B patients (P=0.0192), and histological specimens were obtained in 41 Group A patients (89.1%) and 65 Group B patients (86.7%). Diagnosis of malignancy by cytology was positive in 33 Group A patients (78.6%) and 72 Group B patients (94.6%) (P=0.0079). Malignancy by both cytology and pathology was found in 43 Group A (93.5%) and 73 Group B (97.3%) patients. The mean period from the puncture until the cytological diagnosis in Group B was 1.7 d, which was significantly shorter than that in Group A (4.1 d) (P < 0.0001). Severe adverse events were experienced in two Group A patients (4.3%) and in one Group B patient (1.3%). CONCLUSION: EUS-FNA, as well as percutaneous needle aspiration, is an effective modality to obtain cytopathological confirmation in patients with advanced PC. | Masato Matsuyama Hiroshi Ishii Kensuke Kuraoka Seigo Yukisawa Akiyoshi Kasuga Masato Ozaka Sho Suzuki Kouichi Takano Yuko Sugiyama Takao Itoi | 2013 | World Journal of Gastroenterology2013，19，15： | 5 |

| 3 | Monomorphic epitheliotropic intestinal T-cell lymphoma presenting as melena with long-term survival: A case report and review of literature显示文摘BACKGROUND Monomorphic epitheliotropic intestinal T-cell lymphoma(MEITL)is a rare primary intestinal T-cell lymphoma,previously known as enteropathy-associated T-cell lymphoma type II.MEITL is an aggressive T-cell lymphoma with a poor prognosis and high mortality rate.The known major complications of MEITL are intestinal perforation and obstruction.Here,we present a case of MEITL that was diagnosed following upper gastrointestinal bleeding from an ulcerative duodenal lesion,with recurrence-free survival for 5 years.CASE SUMMARY A 68-year-old female was admitted to our hospital with melena and mild anemia.An urgent esophagogastroduodenoscopy(EGD)revealed bleeding from an ulcerative lesion in the transverse part of the duodenum,for which hemostatic treatment was performed.MEITL was diagnosed following repeated biopsies of the lesion,and cyclophosphamide,doxorubicin,vincristine,and prednisone(CHOP)chemotherapy was administered.She achieved complete remission after eight full cycles of CHOP therapy.At the last follow-up examination,EGD revealed a scarred ulcer and 18Fluorodeoxyglucose(18FDG)positron emission tomography/computed tomography showed no abnormal FDG accumulation.The patient has been in complete remission for 68 mo after initial diagnosis.CONCLUSION To rule out MEITL,it is important to carefully perform histological examination when bleeding from a duodenal ulcer is observed. | Sotaro Ozaka Kunimitsu Inoue Tomoya Okajima Takako Tasaki Shimpei Ariki Hideki Ono Takeaki Ando Tsutomu Daa Kazunari Murakami | 2021 | World Journal of Gastroenterology2021，27，38： | 3 |
